Title: Apparatus for measuring the distortion of data signals
IPC: H04L25/02
Filed: 1974-09-18
Abstract: 1479053 Data transmission: distortion measurement SIEMENS AG 18 Sept 1974 [22 Nov 1973] 40608/74 Heading H4P Data distortion is measured by apparatus comprising a counter operable continuously from a set initial to a set final value during, or overlapping each data signal element, which count is inserted into a store at measuring pulse instants coincident with flanks of each data signal during which signal an interrogation pulse produced intermediately of the flanks, causes issue of the previously stored count to a decoder which controls a display device.  Counter ZA is operated by a clock pulse train ZT, from say a quartz crystal oscillator, and counts from a set initial to set final e.g. 0-99, normally an expected pulse duration from flank to flank. If incoming signal is distorted, then flanks arrive earlier or later hence count Z is indicative of distortion measurement. Data signals DS are applied to input stage EI which produces measuring pulses MI at each signal flank which enable SP to intermediately store instanteous count Z. In the middle of the following data signal DS, an interrogation pulse AI enables gate SS to pass stored count in SP to decoder D.C. output from which is applied to display device AZ. Pulse AI is produced from middle signal pulses MS via generator SM. Each SM pulse indicates the middle of a data element and is for example of 6% data signal duration; MS is also conducted to a blocking gate in E1 which prevents production of an MI pulse during occurrence of an MS signal thus prevents stored count in SP changing during decoding. If timing is correct a 0% signal is displayed. If transition is late relative to one complete cycle of ZA then the output represents percentage distortion. If the transition is early a measuring pulse causes instantaneous count e.g. of 75 to be placed into store SP. At a time t10 (see Fig. 3 not shown) count 2 again reaches its final value and resets. At the next interrogation pulse the stored count is transferred via SS to decoder D.C. hence a leading distortion of 25% will be displayed. If distortion value is to be displayed only on change from 1#0 or 0#1 this can be achieved by introducing a signal (PS or NS = 0) into E1. Gate SS alternatively may be placed after decoder D.C. or eliminated if a switchable decoder is used.

Title: Electric switches
Inventor: LOWE SIDNEY ROLAND
IPC: H01H21/36
Filed: 1958-12-23
Abstract: 871,122. Snap-action switches; switch covers. MIDLAND ELECTRIC MANUFACTURING CO. Ltd. Dec. 21, 1959 [Dec. 23, 1958], No. 41433/58. Class 38 (5). A switch enclosed in a casing has mounted on the exterior of the movable lid an angularlymovable operating member and on the interior of the lid a pivoted arm moved by the operating member and having at its free end a laterallyextending fork which coacts with projections on a contact-driving member to close the switch, and with a fixed abutment on the casing to prevent the lid being opened whilst the switch is closed. Closure of the lid whilst the switch is in the closed position is prevented by the engagement of the fixed abutment with a projection on the contact-driving member. The movement of a hand-operated lever 25 mounted on the lid 6 rotates an associated arm 23 bearing a fork member 24 which bears against a projection 19 to rotate a member 11 mounted on the switch casing. As the member 11 rotates, a slot 12a therein moves a lug 14 to rotate the contact spindle 8. Continued movement of the hand lever 25 causes an over-centre spring 17, engaging a projection 16 on the contact spindle 8, to snap movable contacts 7 into engagement with stationary contacts 9. The arm 23 is now beneath an abutment 22 mounted on, or part of, the switch casing and the lid 6 is thereby prevented from being opened (Fig. 4). Should the spring 17 fail to close the switch, abutment of the fork 24 against projection 20 provides a positive closing action. When, in order to open the switch, the handlever 25 is returned, fork 24 strikes first an abutment 21 and then projection 20 to rotate the member 11. After a while the slot 12a in member 11 overtakes the lug 14, spring 15 being weak, and so drives the contact spindle 8 until the over-centre spring 17 snaps open the contacts. When, with the switch in the open position (Fig. 2), the lid 6 is opened it is possible for test purposes to insert a tool through an aperture in the abutment 22 and so operate the contact-driving member 11 to close the switch. If an attempt is then made to close the lid 6, the fork 24 will strike either the fixed abutment 22 or the abutment 21 (Fig. 4), on the contact member 11 according to the position in which the hand-lever 25 has been left. The hand-lever 25 is biased by an over-centre spring into each of its two limit positions, and may be locked in either position by passing the staple 29 of a padlock through its stem, thus depressing a spring-loaded stop 28 to prevent movement of the fork 23.

Title: Digital shift register
IPC: H01L27/07
Filed: 1973-09-04
Abstract: 1435347 Transistor switching circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 4 Sept 1973 [7 Sept 1972] 41477/73 Heading H3T [Also in Division G4] A digital shift register comprises a chain of series connected emitter followers 1-5 (Fig. 1), the inputs of which are each connected to a storage capacitor 22, 33, 44, 55 and an electronic switch 10, 24, 34, 45, 56, the inputs of adjacent emitter followers being connected to separate clock lines via variable capacitors 12, 13, 14, 15. The shift register which is preferably integrated in a semi-conductor body may comprise three stages per bit and three clock lines but as described four stages per bit each having insulated gate type FET emitter followers and switches, and two clock lines 40, 41, are used. In a first time interval t 1 , the voltage of clock line 41 is E voltage and if a "1" exists at the gate of transistor 1 the capacitance at junction 80 constituted by the sum of the capacitors 12, 22 will be charged. During the second time interval t 2 , the voltage on line 42 is also E volts so that transistor 24 conducts to discharge the capacitance at junction 81. In a third time interval t 3 , only clock line 40 is at E volts and transistor 2 conducts so that the capacitance at junction 81 is charged and in a fourth time interval t 4  clock line 43 is also at E volts so that transistors 10, 34 conduct to discharge the capacitances at junctions 82, 80. Consequently the input data has been shifted to junction 81. After a further four time interval the data is shifted to junction 83 and new data may be entered.  By including a diode between the variable capacitance 12 and drain of transistor 2 to ensure the transistor 2 passes current in only one direction the read in rate may be doubled. Alternatively the diode may be connected between the source of transistor 2 and the drain of transistor 24.

In a dynamo-electric machine, e.g. turbo alternator or synchronous condenser, comprising on a cylindrical rotor a winding whose electrical conductors A1 . . . B2, Fig. 2, carry D.C. excitation current and are cooled by direct contact with a liquid e.g. water, the liquid is fed into and removed from the conductors at places of substantially equal potential. Such places are formed by cross-connections C 1 , C 2  at the mid-points of the winding to which the current is applied at connections D, E which also convey the liquid from two conductors 10, Fig. 14, extending along the shaft from slip rings 23, 24; the current may be derived from rotating rectifiers fed by an A.C. exciter, instead of the slip rings. Each winding and shaft conductor has two passages through which the liquid flows in opposite directions, and the rotor may be in a hydrogen atmosphere.

Title: Apparatus for the continuous heat treatment of elongate material
Inventor: MORGAN ROBERT FREDERIC JENKIN
IPC: C21D9/56
Filed: 1961-11-21
Abstract: In apparatus for the continuous heat treatment of elongate metal the latter is guided in turn through a preheating chamber, past a heating means, and through a cooling chamber, each chamber consisting of an elongated duct through which the strand passes. The apparatus furthermore includes means for circulating a heat-transfer fluid from the cooling to the heating chamber, the fluid flowing through each chamber in a direction opposite to the movement of the material under treatment.  As illustrated in Fig. 1, strip 11 enters the apparatus through rolls 13, passing then through preheating chamber 18, past induction heater 46 and through cooling chamber 19, being reheated if necessary by heater 47 before leaving by pinch rolls 48.  Heat transfer fluid, which may be lead-bismuth alloy, is circulated from reservoir 36 in the arrowed direction by pump 37.  Superstructure 17 may be filled with an inert gas.  The construction of chambers 18, 19 is shown in Fig. 2; each chamber consists of two ducts e.g. 20, 21, unrestrained at their upper ends and attached at their lower ends to cylindrical vessel 22.  This vessel has detachable end plates 28 carrying bearing blocks 30 in which are mounted guide rolls 31; the plates also are provided with annular channels 50 through which cooling liquid is passed to prevent leakage of molten metal. <PICT:1006998/C6-C7/1> <PICT:1006998/C6-C7/2>

Filed: 1959-12-08
Abstract: 870,242. Spinning tops. FUCHS, F., [trading as FUCHS, M., [Firm of]]. Dec. 8, 1959 [Dec. 10, 1958], No, 41706/39. Class 132(3)... A spinning top comprising a transparent upper part a has a hoop f which normally lies loose on a disc e but which, during spinning of the top, rotates and rides up and down a guide member g. Due to centrifugal force the hoop rides up the sloping surface of the guide member g until it reaches the position shown in dot and dash lines. Thereafter, as its momentum diminishes, gravity causes the hoop to drop again on to the disc whereupon the action is repeated during spinning of the top. As shown, the hoop represents a hula hoop rotating around a doll h which may be stationary, the guide member g being of transparent synthetic material. In an alternative, the doll may rotate, e.g. at a slower speed to that of the upper part of the top, a disc supporting the doll being connected to a reduction gear rotating with the top's driving spindle. In further embodiments, several differently coloured hoops, which may be of different diameters, surround the guide member g and the movement of these hoops produces a colour effect. A soundproducing device may be built into the top's casing.

Abstract: 1446946 Cooling steel wire DEMAG AG 7 Sept 1973 [7 Sept 1972] 42145/73 Heading C7N [Also in Division B3] A method of cooling hot metal wire or rod leaving the final stand of a rolling mill, wherein the wire or rod 3 is wound under tension into a coil 5 composed of a plurality of superimposed layers of turns, the innermost layer of the coil being supported during winding; the winding operation being carried out by rotating the coil about its axis, the cooling operation being carried out using liquid coolant M applied to the coil, either (a) in one or more regions of each layer of turns, Fig. 4, the or each region advancing axially of the coil, or (b) throughout the entire length of the coil, Fig. 5 (not shown), after the winding of each layer has been completed. In one embodiment the lower part of the coil is enclosed within a trough 6 with hollow beams 7 extending alongside a drum 2. The beams 7 are provided with nozzles 8 for discharging water as sprays 9 on to the coil 5. The beams are displaceable and the discharge from the nozzles may be controlled. The wire or rod is subjected repeatedly and alternately to both cooling and temperature equalization phases while it is being wound on to the drum until it is covered by a subsequent layer. In a modification, Fig. 5 (not shown), the nozzles are dispensed with and the trough is filled with a coolant (11) to allow partial immersion of the coil The method provides a reasonably short cooling period and yet the transformation of the steel is such that the structure is predominantly pearlitic, Fig. 1 (not shown).

Title: Process for the removal of asphaltenes and ash-forming constituents from residual petroleum fractions
IPC: C10G53/04
Filed: 1961-11-27
Abstract: Asphaltenes and ash-forming constituents are removed from a residual petroleum oil fraction by precipitating these constituents with a hydrocarbon with 4 to 9 carbon atoms in the molecule, with or without substituted polar groups, and having a surface tension with respect to air of less than 24 dynes/an (at 25 DEG C.), and completely or partially separating the precipitated constituents from the oil by passing the mixture through one or more hydrocyclones and/or multicyclones.  Suitable precipitants include paraffins such as pentane, hexane, heptane, and iso-octane, methyl cyclohexane, dimethyl cyclopentane, diethyl ether, ethyl acetate, and mixtures thereof.  Technical mixtures, especially those which contain pentane, such as are obtained in the straight run distillation of crude oil, may be used.  The oil phase and/or the asphaltene suspension phase may be passed through further cyclones, further precipitant being added to the asphaltene suspension if desired.  Specification 634,135 is referred to.

Abstract: 1,094,952. Automatic brake adjuster. WAGNER ELECTRIC CORPORATION. Oct. 6, 1965 [Jan. 27, 1966], No. 42488/65. Heading F2E. A brake adjuster includes rotatable adjustable means having a notched peripheral surface and a radially extending follower surface, lever means pivotally mounted adjacent the adjustable means and having spaced driving and follower means thereon normally engaged with the said peripheral and follower surfaces, respectively, at spaced locations and spring means connected with the lever means exerting a force to urge the driving means into engagement with the peripheral surface and urging the follower means on the follower surface towards the said peripheral surface. The hydraulically operated actuator shown has two levers 49 each loosely pivoted on a pin 54 and having foot portions 52 abutting the side faces of the star wheels 40. During brake application the pistons 41, 41a move outwards with the star wheels, allowing the bell crank levers to rotate under the action of spring 64. Excessive movement of a piston due to shoe wear allows the portion 51 to fall behind a star wheel tooth and turn the wheel, as the brake is released, to reduce the clearance. The spring 66 has its centre engaged below a lug 66 so that it acts obliquely on the bell cranks 49; this and the disposition of the foot portions 52 cause the cranks to tilt on their pivots when the star wheels are rotated manually to position each foot on top of the teeth with the portion 51 disengaged therefrom to permit easy manual adjustment. In a second embodiment (Figs. 6 and 7, not shown) a mechanical wedge type actuator is described, wherein a single bell crank is provided with a coil spring.

Abstract: 1370342 Copying by scanning MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 14 Sept 1971 [16 Sept 1970] 42858/71 Heading H4F A facsimile transmitter, Fig. 2, codes the run lengths of successive black and white marks on a scanned document 10 into digital form at 3, only one, or at most nine, marks being coded during each line scan. The fibre optics scanning tube 7 continuously scans one line of document 10, and the output from a phot-ocell 11 is fed to a control circuit 2. One (or more) mark signal is read by circuit 2 and passed to encoder 3 and while this mark is being encoded the tube 7 continues to line scan but circuit 2 does not read the resulting output. As the penultimate coded bit is fed through a register 6 a signal is generated to cause the circuit 2 to read the next mark (or group of marks). When all the marks related to one line have been encoded a signal causes sub-scanning control circuit 4 to advance the document 10. The correct mark (or group of marks) to be read is selected by use of a coincidence circuit (28, Fig. 6, not shown) and two binary counters, one (25) counting pulses related to the length of a specific line already read, and the other (26) counting pulses from the beginning of the required line scan of tube 7, circuit 4 being operated by overflow of the first counter (25), the equivalent receiver (Fig. 10, not shown) using similar counters and coincidence circuit as well as receiving the stepping pulses which are amplitude modulated on to a carrier, the coded marks being transmitted on a carrier at a different frequency. The coding of the pulses is such that mark run lengths of 1 and 2 (as measured by clocking pulses) are coded as 10 and 11 respectively whereas a number n # 3 is coded by taking the binary number of n-1. This binary number has m digits and m - 1 zeros are added in front of the binary number n-1, e.g. if n = 3, n-1 = 2, binary n-1 = 10 so m = 2, m-1 = 1, and coded number = 010. The resulting signal is decoded by counting zeros to determine the divisions between coded marks as shown in Fig. 9.

Title: Recovery and production of cyclohexanone
IPC: C07C45/00
Filed: 1960-12-14
Abstract: Cyclohexanone is recovered from a mixture consisting mainly of cyclohexanol and cyclohexanone by fractionating the mixture to separate an overhead fraction consisting predominantly of cyclohexanone and a cyclohexanol-enriched bottoms fraction, dehydrogenating the bottoms fraction to produce a further amount of cyclohexanone and recycling the dehydrogenated bottoms fraction to the fractionating stage.  The starting material may be the product mixture derived from the partial oxidation of cyclohexane with molecular oxygen from which unreacted cyclohexane has been separated. Preferably the fractionation takes place in two steps, in the first of which a heavy ends fraction is removed and in the second of which the mixture is separated into a cyclohexanone fraction and a cyclohexanol fraction, the latter being dehydrogenated and the product being recycled to the first step of the fractionation. The mixture is preferably treated with an aqueous alkali solution (for example as in Specification 966,546) prior to the separation into cyclohexanone and cyclohexanol fractions. The fractional distillation steps are preferably effected at sub-atmospheric pressure and the cyclohexanone fraction may be further fractionally distilled at a higher pressure than the preceding distillation, but not above atmospheric pressure, to recover substantially pure cyclohexanone. The dehydrogenation may be effected at 200 DEG C. to 550 DEG C. and 3 to 50 p.s.i. absolute using a dehydrogenation catalyst, such as zinc oxide (as described in Specification 909,227) copper or brass.  The process may be batch-wise or continuous.  In an example, an oil feed obtained by the oxidation of cyclohexane and augmented by the products of dehydrogenation of the cyclohexanol fraction is distilled at 16 mm. to separate a cyclohexanol-cyclohexanone mixture from heavy ends, the product is scrubbed with sodium hydroxide solution, the oil phase is fractionated at 16 mm. and the overhead is further fractionated at 60 mm. giving cyclohexanone; the bottoms comprising cyclohexanol is dehydrogenated at 420 DEG C. using zinc oxide catalyst and the dehydrogenation products, after removal of hydrogen, are recycled to mix with the oil feed.  Specification 975,949 also is referred to.
