Title: Gas purifying apparatus
IPC: F04B39/16
Filed: 1962-05-15
Abstract: 964,927. Tube-type heat exchangers. R. P. ADAMS CO. Inc. May 15, 1962 [May 23, 1961], No. 18602/62. Heading F4S. [Also in Divisions B2 and F2] A gas-purifying apparatus comprises heatexchangers 10, 11 connected in series and a gasliquid separator (see Division B2) in series with the heat-exchanger 11 and delivering purified gas through an outlet pipe 127 to the heat-exchanger 10 whereby the purified gas is heated by the incoming gas to be purified. Compressed air laden with oil and water vapour is introduced through an inlet pipe 15 into the heat-exchanger 10 where it undergoes preliminary cooling by the counterflow of the purified gas and then passes through the heatexchanger 11 where it is further cooled by circulating water. The oil and water vapour is thereby condensed out and is removed from the air as it passes through the separator 12. The heat-exchanger 10 comprises finned air-carrying tube 27 supported within a shell 20 between headers 25, 28, the header 25 being clamped between flanges 17, 21, respectively, on the cover 16 and the shell 20, and the header 28 being sealed to the shell by asbestos packing compressed by a gland 48. A longitudinally extending chamber 41, defined by an arcuate wall 40, Fig. 4, connected to the underside of the shell, serves for the passage of purified gas which enters through an opening 42 into the shell where it follows a tortuous path in flowing towards the outlet 145 due to the arrangement of baffles 35, 38 supported on stay rods 32, 37. The heat-exchanger 11 is of similar construction except that the tubular gland 92 at its outlet end serves also as a connection between the heat-exchanger and the separator 12 and sealing is effected by a pair of packings between which is interposed a vent ring (see Division F2) serving to vent the packing to atmosphere and to detect gas or water leakage. Cooling water is introduced through a conduit 80 equipped with control valves 81, 82 and leaves through a conduit 78 having a control valve 79. Thermometers are provided at 18, 57, 85, 115 and 146.

Filed: 1923-07-20
Abstract: 215,227. Lamont, J. July 20, 1923. Lawn-tennis net supports. - A device for clamping the strained cord that carries a lawntennis net comprises a cylindrical block A housed within the post and provided with an axial bore B and a central cavity C. A bellshaped member D, bored at E, is housed in the cavity C, and a square projection F thereof is internally screw-threaded to receive a bolt H. The cord is passed through the bores B, E, which register with one another before the clamp is applied. The cord is clamped by the rotation of the bolt H, which draws the member D forward and causes the inner end of the bolt to bite into the cord. The bolt is prevented from riding forward bodily by means of a wing- nut J which bears against a washer inserted between it and the post. The wing-nut is finally tightened to secure the parts in their adjusted positions.

Title: Improvements in or relating to conveyor systems
IPC: B65G47/61
Filed: 1939-06-27
Abstract: 531,263. Conveyers. KING, Ltd., G. W., and KING, D. M. June 27, 1939, No. 18716. [Class 78 (i)] Articles such as coils of wire A are hung on hooks 12 pivoted to members which are incorporated in the run of an endless driving chain 10 and carrying rollers engaging the channelled guiding and supporting bar 11. The coils are delivered one at a time down a shoot to the lift cage 22. As each empty hook registers with the lift, it closes a contact switch temporarily and starts the motor 26 to lift the loaded cage. The coil tilts the horns 13 of the hook in its upward movement until the main hook portions pass inside it. When the cage is lowered again by the actuation of a second contact switch the coil remains suspended on the hook. Depending bars on the framework may maintain the horns 13 in their tilted position for a short time to assist the transfer. The suspended coil is carried, for example, through a treating bath C and is then delivered to a carry-off belt conveyer D by the horns 13 contacting skid surfaces which causes the hooks to tilt. Fig. 9 shows the means for feeding the lift cage. The coils are placed on arc-shaped rests 31 carried by an inclined endless chain. The weight of the coil rotates the chain by gravity. Side guides 32 maintain the coils approximately upright during the journey. A stop, synchronized with the cage, is lowered to allow one coil to move into the cage when the latter is at the bottom of its travel.

IPC: C21C5/46
Filed: 1962-05-15
Abstract: 956,192. Variable throw cranks. PINTSCH BAMAG A.G. May 15, 1962 [May 18, 1961], No. 18750/62. Heading F2K. [Also in Division F4] An oxygen blowing lance 9, Fig. 1, is moved to and fro in a cage 13 which is swung about pivots 46 on the hood of a steel converter 1. The swinging motion is controlled by a crank disc 19 through a connecting rod 18. The disc 19 has a slot 20 of T-section, Fig. 3, so that the stroke may be adjusted. The connecting rod 18 is very short, Fig. 2, so that it can be arranged that the swing of the lance varies. The swing drive is mounted on a pivoted platform 22, so that the centre point of the lance swing can be adjusted by altering the length of link 23.

Title: Improvements in and relating to electric generating equipments
IPC: H02J7/16
Filed: 1944-10-02
Abstract: 582,384. Electricity supply; selfcontained supply systems. PARTING- TON, W., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Oct. 2, 1944, No. 18796. [Class 38 (iv)] In an axle-driven generating equipment for railway locomotives, or other vehicles, the armature winding 1 of an alternator is connected through a rectifier 7 to a battery 3 supplying an auxiliary load 4. The alternator field winding 2 is also connected across the battery through a voltage.relay 14 and a switch 12. The contacts of relay 14 are normally closed, but are opened in response to the battery voltage attaining its fully-charged value, whereupon a resistance 10 is inserted in the field circuit. The switch 12 is adapted to be closed by means of a reciprocating lever 21 connected to the regulator 22 of the locomotive so that only when the regulator is moved to start the locomotive, will switch 12 close and the alternator generate current. A substantially constant-current output is obtained from the alternator by designing it so that except at low speeds the battery voltage and hence the alternator output is a small proportion of the internal reactive drop in the. latter, so that over a wide range of normal running speeds the alternator output current is substantially equal to its short-circuit current. The switch. 12 may be operated by a piston working in a cylinder connected with the main steam pipe between the regulator 22 and the cylinders of the locomotive, or any means responsive directly or indirectly to the condition of a control member governing the application of driving power to the locomotive. A swamping resistance 23 may be connected in the alternator field circuit to reduce variations in excitation with temperature changes.

Title: Device for changing knitting density and changing speed of feeding  yarn according to changes in knitting density in circular knitting  machines
IPC: D04B15/48
Filed: 1973-04-19
Abstract: 1380224 Knitting; yarn feeding ELITEXZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI 19 April 1973 [26 April 1972] 18907/73 Heading D1C In positive yarn feeding the yarn passes in an S shaped path round two rollers 21 which do not touch (Fig. 1) the roller driving the other through gears 24. To vary the feeding speed with knitting density in a circular knitting machine a rod 12 is moved lengthwise as the needle cylinder changes height. A friction driven disc 2 on the rod then moves across the face of a driving disc 3 to alter the gear ratio, and thus the speed of the rollers 21. To stop feeding, one roller may be swung in an arc round the other so that the yarn's S shaped path becomes straight (Fig. 3, not shown), the yarn then passing between the rollers but not touching either of them. In other embodiments (i) two rollers are in contact (Fig. 5) pinching the yarn between them, one roller also being in contact with and driven by the disc 3; (ii) in a multifeed device (Fig. 6) a shaft 18 is driven by the disc 3, and a plurality of rollers 20 may be moved into contact with the shaft independently, each roller feeding a yarn independently.

Title: Improvements in telescopic and expanding tables
IPC: A47B1/05
Filed: 1930-06-20
Abstract: 349,804. Expanding tables. POUNDS, A. W., 21, Grove Road, and GREENLAND, H., 3, Bank Side, Hafod Road, both in Hereford. June 20, 1930, No. 18920. [Class 52 (iii).] In an expanding table of the kind wherein means are provided to raise and lower a central leaf to enable end leaves to be inserted or withdrawn (for example, the table described in Specification 210,469, [Class 52 (iii), Tables &c.]), the end leaves are connected by hinges 18 to sliders 19, the undersides of which are horizontal and move on rollers 21 and a transverse bearer 22. Between each pair of sliders is a rod 23 ; these are fixed at their outer ends to the end leaves, and bear " cam " surfaces 25. When an end leaf is drawn out, the rod 23 tilts in the slot 24, and the upwardly-sloping part 26 of the cam 25 rides over a roller 28 on an abutment 27. This tilting raises the end leaf on its hinges 18 until it is clear of the central leaf ; at the same time, wedges 29 on the sliders 19 engage with wedges 30 attached to the underside of the centre leaf and raise it to the level of the fixed panel 13. When the end leaf is fully out, the inner end of the rod 23 falls upon the bearer 22, thus enabling the leaf to fall to the level of the upraised central leaf.

Title: Two detector neutron porosity and water salinity apparatus and methods
IPC: G01V5/10
Filed: 1974-05-01
Abstract: 1471788 Borehole logging SCHLUMBERGER Ltd 1 May 1974 [1 May 1973] 19103/74 Heading G1A Borehole logging apparatus, operating by irradiating the formation with neutrons and monitoring (thermal) neutron populations in the formation at two locations by means of two detectors spaced at different distances along the logging tool from the neutron source, is used to measure formation porosity # and formation fluid salinity, WS by deriving a neutron population measurements ratio R and, combining this with a neutron absorption characteristic such as thermal neutron decay time # or microscopic capture cross-section #, in accordance with predetermined relationships to calculate the required quantities. In the embodiment described, Fig. 1, the near and far detectors 20, 22 are sodium-iodide scintillation crystal detectors coupled to photomultipliers monitoring 7-radiation from thermal neutron capture. Alternatively, thermal neutron sensitive detectors e.g. He-3 filled proportional counters may be used. The neutron source 18 is arranged to produce discrete pulses of 14MeV high energy neutrons of one decay time (#) duration, at intervals of 10#. The neutron population is sampled in the interval between the irradiation pulses: at 2# after the irradiation pulse has ended for a duration of #; at 3# after irradiation has ended for a 2# duration; and at 6# after irradiation has ended for 3# duration. The first and second sample period counts N 1 , F 1  and N 2 , F 2  represent neutron population counts and the third N3, F3 represent gamma backgrounds to be subtracted from N 1  and/or N 2  and F 1  and/or F 2  during calculations. # is calculated from the ratio of the net N 1 , N 2  counts by adjusting the sample intervals until the ratio equals 2À0 when the first interval is of length # and may be used to control the timing and duration of neutron source energization in order to optimize the measurement system. The neutron population function calculated is R, equal to N<SP>1</SP>-<SP>1</SP>/ 3 N 3 /F 1 +F 2 -F 3  a more accurate function than the simple ratio of the net N 1 , F 1  counts, and is calculated using the circuitry shown in Fig. 1. A suitable computation circuit for combining # (obtained from #) and R to calculate # and WS is detailed in Fig. 4 (not shown), or an appropriately programmed computer may be used. The quantities shown in Fig. 1 at 40 may be recorded on magnetic tape or visual recording apparatus. Parts of the circuit may be on the borehole tool. The invention need not be carried out using a pulsed source and measuring neutron populations in the intervals between pulses. A steady state system using a continuously operating source may be used and R obtained from counts for the near and far detectors, in which cell #, or #, is derived by other appropriate apparatus.

Title: Improvements in variable speed electric drives
IPC: H02P7/06
Filed: 1948-07-16
Abstract: 658.282. Motor control systems. WARNER & SWASEY CO. July 16, 1948, No. 19118. Convention date, July 25, 1947. [Class 38(iii)] [Also in Group XXIV] A shaft 61 is rotatable over a wide range of speeds, and over which the power transmitted remains substantially constant, by a D.C. motor 10 and epicyclic speed-change gear 13 in association with a controller 40, 41 by which both the motor excitation may be varied and the gear ratio controlled. The range of speed of the shaft extends both above and below the motor speed under conditions of full armature and field excitation. Clockwise rotation of the controller from the zero speed position first progressively cuts out resistance 21 of rheostat 19 to increase the voltage applied to the armature of the motor and then inserts resistance 32 of a rheostat 20 to reduce the field excitation, which had previously been maintained at its maximum value. During this stage a relay R has been de-energized and its normally closed contact R-2 maintains an energizing circuit for a stationary electromagnet 62, 63 which locks the outer ring wheel 50 of the gear, so that the gear effects aspeed reduction. Upon further slight rotation of the controller the initial armature voltage and field excitation conditions are restored by resistors 24, 34 but the relay is now energized over contacts 44, 45. and closure of its normally open contact R-1 energizes an electromagnet 53, 54 to lock gear ring 50 to the shaft 61, thereby effecting a solid drive 'between the armature shaft 49 and shaft 61. Further rotation of the controller again. accelerates the shaft by progressively cutting cut resistor 24 and then inserting resistor 34 to increase the applied armature voltage and weaken the field excitation.

Title: Improvements in and connected with the automatic control of combustion furnaces
Inventor: BURCKHARDT CHRISTOF WALTER
IPC: F23N5/20
Filed: 1956-06-20
Abstract: 869,876. Photo-electric control. RHEOSTATIC CO. Ltd. June 6, 1957 [June 20, 1956], No. 19118/56. Class 40(3) [Also in Group XI] In a safety control circuit for a burner including a photo-cell 18 illuminated by the burner and adapted to energize a relay 16 holding closed a switch 1, energizing a motor 2 supplying oil and air to the burner, the relay is biased by a permanent magnet 25 to open switch 1 and is magnetized in reverse direction, also to open switch 1, if the photo-cell is short-circuited. In normal operation the current through the photo-cell, when illuminated, is just sufficient to demagnetize the relay and to allow the relay to hold the switch 1 closed. At starting the switch is closed by a bimetal strip 3 heated by an electric heater 4 energized by a switch 6 which is opened by the relay 16 when the photo-cell is illuminated. The switch 6 also energizes an igniter transformer 8 simultaneously with the heater 4. The relay 16, when demagnetized, also closes a switch 10 in series with a heater 11 in parallel with a thermostat 7 responsive to a temperature to be controlled. If damage to the photo-cell causes the switch 1 and the switch 10 to remain closed after the stopping of the burner by the opening of the thermostat 7 the heater 11 is energized and heats the bimetal strip 3 which eventually opens a lock-out switch 5. In a modification, Fig. 2 (not shown), the photo-cell is in parallel with the relay 16. The Provisional Specification also describes two further circuits in which the relay bias magnet is omitted. In the first of these two circuits the photo-cell and the relay are in series and a resistance having a negative coefficient of resistance is shunted across the relay. If the photo-cell is short circuited the temperature of the resistance increases so that it short circuits the relay and consequently the relay is demagnetized and the contacts are moved to the no-flame condition. In the second of these two circuits the relay coil is divided into two sections, one of which is in series with the photo-cell. If the photo-cell is short circuited the increased current in the series section of the relay coil forces current through the other section against the opposition of a battery and the relay becomes demagnetized. Specification 836,119 is referred to in the Provisional Specification.

Title: Procedure and apparatus for monitoring the pressing force of a tablet press
IPC: G01L1/22
Filed: 1976-05-10
Abstract: 1511792 Controlling tabletting presses WILHELM FETTE GmbH 10 May 1976 [9 May 1975] 19138/76 Heading B5A In a rotary table tabletting machine, the pressing force is monitored by obtaining a mean A of the pressing force based on successive maxima and comparing the mean with upper and lower pre-set limits (not shown in Fig. 3). Also a pair of limits B, C are derived from the mean A and the maxima of successive tabletting operations are compared with these limits. The former enables the press to shut down should the mean move beyond the pre-set limits whilst the latter enables the press to shut down should an event occur which significantly effects an individual maximum but does not significantly effect the mean (for example a broken ram or double filling). In the preferred embodiment, the force of the rams 1, 2 as they are pushed together to effect a pressing operation by rolls 3 and 4 is measured by measuring strips 5, 5<SP>1</SP> on the roll supporting frame. The resultant signal is sent via a Wheatstone Bridge and an amplifier to a logic device which derives the mean value and the various limits and effects the desired comparisons. The device is operative to shut the press down if necessary and to numerically indicate at which ram a fault is occurring.

Abstract: 1379686 Radio direction-finders INTERNATIONAL STANDARD ELECTRIC CORP 25 April 1972 [7 May 1971] 19143/72 Heading H4D In a two-channel direction finder, the relative gain and phase of receivers 6, 7 is adjusted while their inputs are connected to artificial antenna circuits 9, 10 fed from a common signal source, e.g. sense antenna 45. The artificial antenna circuits simulate loops 1, 2. Adjustment ensures that the receiver output signals ratio U6/U7 = U1/U2 (or is a known multiple thereof), the signals U1, U2 being from loops 1, 2, the loops being disconnected during adjustment periods. In an alternative embodiment (Fig. 5, not shown), a circuit (55) determines which loop (1), (2) is giving the strongest signal and feeds this signal, via a transformer (56), to the artificial antenna circuits, in place of the sense antenna signal. If cables 4, 5 are well matched, the interconnecting switches 40, 41, (54), (41) (Fig. 5) may be inserted at the receiver end of the cables.
