Abstract: 410,974. Calculating-apparatus. HOGFORS, H. F. B., 134, Sara Moraeas Võg, Skarpnõck, Sweden. June 2, 1933, No. 16051. [Class 106 (i).] Transfer mechanism. -In calculating- machines and cash registers in which the totalizer shaft is moved to and fro to engage or disengage the numeral wheels with or from the actuating racks which are slidably mounted on the main differential actuators transfer between the numeral wheels is effected by a transfer tooth 10, Figs. 1, and 3, which displaces a release slide 1 and a catch or lever 18 pivotally mounted on the actuating rack 16, Fig. 2, of the next higher denominational actuator 23 so as to position the catch into operative position with respect to a transfer actuating member 31. Each slide 1 is provided with a roller 3 guided in a slot 4 of a frame plate 2 and with a bent end 5 engagmg a notched recess 6 in the said plate. When a slide is displaced by a transfer tooth it is held in its operated position against the action of the spring 8 by the end 5 engaging the part 13 of the recess. After the differential setting movement of the actuators 23 the totalizer pinions are moved into engagement and on the return movement of the actuators the setting is imparted thereto. On reaching their normal position the rollers 21 of the spring controlled catches 18, if a transfer is to be effected, are acted upon by the rollers 3 which hold the catches in their displaced position. The transfer movement is effected before disengaging the totalizer, by the engagement of a lip 30 on the catch 18 with a pivoted latch 37 on a corresponding slidable carrier member 31, thereby imparting an additional step movement to the appropriate rack 16. The carriers 31 are guided on shafts 32, 33 and each has a roller 49 co-operating with a cam element 41 .. or 44 arranged in staggered relation on the shaft 33 and rocked by a linkage operatively connected to the main operating shaft 57. To ensure that the racks 16 return to their upper position in the event of a spring 19 failing a positive restoring lug 50 is provided on each of the carrier members to engage the lip 30 and a roller 51 on each of the cams 41 ... 44 ensures the return of the carrier members.

Abstract: 1,049,450. Multiplex sound and vision transmission systems. A. BELTRAMI. Dee. 11, 1963 [Dec.11, 1962], No. 41300/65. Divided out of 1,049,449. Headings H4F and H4L. In a television system the composite video signal includes, in each line fly-back period, a plurality of time-displaced line-frequency pulses, the pulses being individually amplitude modulated by a corresponding plurality of separate, e.g. different language, sound signals and one of the pulses also serving as a line synchronizing signal. The pulses occupy an amplitude range in the same direction but exceeding that of the picture signal. The individual pulses are amplitude modulated over separate amplitude ranges so as to facilitate separation at a receiver. The composite signal is completed by a frame frequency pulse which occupies an amplitude excursion opposite to that of the picture signal. At a receiver the sound modulated pulses are separated by a plurality of valve or transistor circuits provided with different biases so that succeeding circuits pass one, two, three &c. of the pulses, antiphase coupling of the pulses from each circuit to the preceding circuit being employed to effect pulse cancellation so that each circuit eventually provides only one of the pulses for an associated sound reproducer.

Title: Improvements in or relating to the vacuum de-gassing of metals
Inventor: FARRER SYDNEY
IPC: F27B5/04
Filed: 1961-11-17
Abstract: <PICT:0965472/C6-C7/1> <PICT:0965472/C6-C7/2> A vessel for the vacuum degassing of molten metal is discharged through two or more barometric legs which open separately into the vessel but which are joined together at or near a common discharge orifice, and which are so arranged that molten metal on the floor of the vessel flows first into one leg displacing air through the remaining legs before the metal enters therein, means being provided for inducing an electric current in the loop formed by the metal in the legs and the pool in the base of the vessel.  The barometric legs may have the same cross-section, or one may have a smaller cross-section than the remainder whereby metal in the former is heated to a higher temperature and circulation occurs by convection. After suitable calibration it is possible to determine the quantity of metal remaining in the vessel by determination of the impedance of the secondary circuit from measurements of the voltage and current in the primary.  As shown in Fig. 1, barometric legs 12 and 14 combine to give a common discharge orifice 22 and leg 14 is surrounded by yoke 24 associated with winding 26.  Weir 32 ensures that metal accumulating in the well of vessel 10 runs first into leg 12, projection 34 giving protection against direct entry of metal into leg 14.  In the variant shown in Fig. 5, the legs discharge from points widely spaced in the vessel.

Abstract: 1,001,041. Transistor amplitude-discriminating circuits; pilot-controlled A.V.C. GENERAL ELECTRIC CO. Ltd. Oct. 23, 1963 [Nov. 1, 1962], No. 41377/62. Headings H3T and H4R. A circuit for producing a predetermined response when the voltage level of an input signal (e.g. a pilot signal in a communication system) falls outside defined limits, comprises two bi-stable trigger circuits one of which changes state when the input signal voltage increases positively to exceed a first voltage level but which does not return to its initial state until the input signal has fallen below a level less positive than the first voltage level and the other of which changes state when the input signal voltage increases negatively to exceed a second voltage level but which does not return to its initial state until the input signal has fallen below a level less negative than the second voltage level. Thus both trigger circuits remain in their initial states so long as the input signal voltage remains within the limits defined by the first and second voltage levels; however, once a circuit has changed state its state is not restored until the input signal voltage has returned to within limits narrower than those defined by the first and second voltage levels. The circuit may form part of terminal receiving equipment in which a pilot signal transmitted with the intelligence signal is used to effect gain control, the circuit serving to indicate when excessive changes on the pilot-signal amplitude, such as would be due to a fault, have taken place. The two bi-stable circuits 43, 44 comprise Schmitt-trigger circuits constituted by transistors 2, 6 and 13, 16 respectively and so biased that for input-signals levels within the defined limits, transistors 6 and 13 are conducting. The circuit 44 includes an inverting output transistor 24, so that for normal levels of input signal, the output transistors 6 and 24 of the circuits 43, 44 are both conducting. The outputs from the two trigger circuits are applied via diode gates 11, 28 to emitter-follower transistor 29; thus for normal input-signal levels both transistors 31 and 36 are conducting and relay 39 is energized. Reversal of the state of either of the bi-stable circuits results in a considerably more negative voltage being established at the base of emitter follower 29, this switching transistors 31 and 36 and so releasing relay 39 to cause an alarm to be operated and/or some other control to be effected. Transistor 22 forms part of the load for transistor 13 and serves to delay the onset of bottoming in that transistor.

Title: Oxo process
IPC: C07C45/50
Filed: 1961-11-20
Abstract: Cobalt is recovered from the degassed liquid product of a cobalt-catalysed oxo reaction by heating the product at a temperature of 100-190 DEG F. and at an absolute pressure of 10-25 p.s.i. with steam, separating from the resulting mixture an aqueous phase substantially free of cobalt, and removing cobalt from the remainder of the mixture.  In one embodiment of the invention the steam is provided at atmospheric pressure or slightly above, and the mixture separates into three phases-a clear top organic phase, a clear aqueous phase and at the interface between the layers a thick black suspension containing the cobalt and referred to as the cobalt "interfacial rag".  The liquid layers can be separated leaving the interfacial rag which can be recovered as a cobalt soap and recycled to the oxo reactor. In another modification the cobalt is converted into a form which passes into the organic layer by passing an oxygen-containing gas into the mixture either at the same time as or subsequently to passing in the steam.  The organic layer is then separated and distilled to give a bottoms fraction containing cobalt which can be recycled to the oxo reactor.  The oxygen-containing gas may be commercial oxygen, air, air diluted with inert gas.  The interfacial rag may be converted to a form suitable for use as catalyst in the oxo reaction by treating it with sulphuric acid to form the sulphate, treating the sulphate with an alkali metal hydroxide and then adding an acid such as oleic acid, linoleic acid, stearic acid or tall oil acid.  Alternatively the interfacial rag may be treated direct with the organic acid while passing oxygen into the mixture.  Specification 682,177 is referred to.

[Also in Divisions B6 and B8] A dispenser for tape which is cut off into predetermined lengths to form labels has a housing 2, an actuating lever 6, a lever 10 carrying a knife edge 12 which co-operates with a resiliently yielding backing 14 carried on another lever 18 connected to lever 10 by a spring 22 providing insufficient pressure for cutting, a self adhesive tape 26 carried on a roll 28 and a printing unit 40 slidable in a slot 2b of the housing 2 so that when lever 6 is operated the jaws formed by members 12, 14 move clockwise gripping the tape so that a length is drawn from the spool. Contact of a follower 18b on lever 18 with a stationary cam 24 on the housing causes lever 18 to move slightly in a counter clockwise sense and increase pressure between members 12, 14 and sever the tape. A cover tape 34 is separated from tape 26 by a deflector 36 and the tape 26 moves over a roller 50 into the nip between members 12, 14. Movement of lever 6 causes the printing roller to descend and press the tape against a backing plate 54 so that a label is printed as the tape is dispensed. The severed label can be applied to the article by means of a roller 16.

Title: High speed printers with column spanning hammers
IPC: B41J9/12
Filed: 1961-11-24
Abstract: 992,590. Selective printers. POTTER INSTRUMENTS CO. Inc. Nov. 24, 1961 [Nov. 25, 1960], No. 42142/61. Heading B6F. [Also in Division G4] A high-speed printer wherein a number of type faces are moved past printing positions in a printing line has a printing hammer which spans at least two type positions on the printing line, the arrangement of type faces being such that they register with the hammer one at a time, and the hammer being operated each time a required type face is in register therewith. As shown in Fig. 1, each hammer such as 13 spans three circumferential rows of type 6, 7, 8 on a continuously rotating cylinder 1, each row comprising a complete set of characters to be printed, and the type faces being staggered circumferentially so that only one type face at a time is in register with a hammer. For each complete line of printing, the cylinder makes three revolutions, and the timing of the hammer 13 is such that during the first revolution it prints a selected type in row 6, during the second revolution it prints a selected type in row 7, and in the third revolution a character is printed in row 8, this cycle being repeated for the next line. Rotating with the cylinder 1 are a hammer tone wheel 22 and clock tone wheel 34. A fixed contact 37 engages contact segments 35 on the wheel 34 so as to transmit tc a counter 41 a pulse for each character passing the printing line, and the character count is applied to comparators 52, 53, 54, one for each character row, connected to storages 60, 67, 74 to which information regarding characters to be printed is supplied. The wheel 22 has contact segments 23 co-operating with fixed contacts 24, 25, 26 corresponding to the three rows and provides timing signals to the hammer operating circuits. By suitable circuitry (see Divisior G4) the operation of the hammers is effected as required. In a modified construction (Fig. 4 not shown), each hammer spans two rows of type and is moved axially a distance corresponding to two rows of type after printing from the first two rows, and then prints from the adjacent two rows, so that four revolutions of the cylinder are required for each line of print. Type on endless bands. According to another construction, Fig. 2, the type are arranged on an endless band 117 in repeated sets of three, each type being separated from the next by three letter spaces and each hammer 124. . . 129 spanning three letter spaces. The paper moves perpendicularly to the band 117 for line spacing, and a complete line is printed during three complete traverses of the belt, each hammer being operated once during each traverse. In a modification of this construction (Fig. 3, not shown), the band is provided with one set of characters only, the spacing of the characters and the span of each hammer being three letter spaces. In this case, a line is printed during one complete traverse of the band, and if a particular character is required to be repeated in adjacent column positions, a hammer is actuated twice in quick succession as the character passes over it.

Title: Improvements in and relating to cryogenic devices and to methods of producing them
Inventor: CLARK TERENCE DANIEL
IPC: H01L39/22
Filed: 1963-10-25
Abstract: <PICT:1023519/C6-C7/1> A cryogenic device comprises a thin striated discontinuous superconductive film in which the distances between the islands in one direction is small enough to permit tunnelling; separation between islands in the direction normal to the first, is greater. Fig. 7 shows a device comprising a layer 4 of lines of isolated islands of superconductor material deposited on a substrate 1 between electrodes 2 and 3. The island structure of the layer, which may be 100-5000<\>r thick, is produced by evaporation of the superconductor material at a high angle of incidence on to the substrate; a pre-coating of a nucleating material in the desired pattern may be used to assist island formation or deposition may be effected through a slotted mask.  Alternatively, the surface of the substrate may be machined to form parallel lines, such as by subjection to an electron beam.  The superconductor material may be Al, Pb, Ni, Ta, Sn, Ti or Va.  The terminals may be of superconductor material, a superconducting ground plane may be provided, and the layer may be protected by a layer of silicon monoxide. The substrate temperature is maintained substantially at the melting temperature of the coating material.
