Patent GB-938317-A (GB)
Title: Improvements in or relating to electronic decade counting circuits
Inventor: ARNOLD JOHN SPENCER
IPC: H03K23/00
Filed: 1962-03-06
Abstract: 938,317. Electronic counters. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. March 6, 1962, No. 8493/62. Class 106 (1). A decade counter with a 2-out-of-5 output comprises five toggles, the first four being arranged as a cascade counter logical circuits being so arranged that a second input to the first stage will turn off said stage at the end of the pulse to be counted only when the first, second and fifth stages have been turned on, further gating means reversing the fifth stage only when the first or third stages assumes the " on " condition. In the quiescent condition all stages MA-ME are in the off condition and transistor T12 is conducting. When counting commences earth pulses superimposed on a negative potential are applied from terminal IP through diode gates D1, D2 to both sides of the stage MA. The pulses from IP are also applied to cut-off inverter T11 connected to a 3-AND gate feeding T1. The counter operates as a cascade counter up to a count of 6 except that the fifth stage ME reverses over diodes D9, D10 when MA or MC changes to on whereby two of the leads A-E are marked for each count. The seventh pulse initially registers as 11101 but as the pulse ends the re-operation of inverter T11 adds one to the cascade part of the counter to change the registration to 00011. Similarly, the tenth pulse initially registers as 11011 which is changed by the addition of one and the turning on of the third stage to reverse the fifth stage to 00110. Counting down is effected by bringing the counter first to the quiescent state 00000 and by applying short pulses to those leads A-E which are not marked in the ordinary 2-out-of-5 representation of the digit concerned. Counting down involves an additional 3-gate GM and proceeds in 3-out-of-5 code until a zero state is reached with all five leads A-E marked.

Title: An improved construction and arrangement of reversing gear for carding engines either flexible or non-flexible bend type
IPC: D01G15/36
Filed: 1925-04-01
Abstract: 252,503. Benson, R. April 1, 1925. Carding-engines.- In a reversing-gear for the main cylinder of a carding-engine to enable it to be driven for grinding, the driving-pulley 7 is provided with an internal gear 8 meshing with planet-pinions 9 carried by a housing 4 mounted on a fixed boss 3 projecting from the bearing 2 of the cylinder shaft 1. The pulley 7 turns loosely on the sleeve 5 of the housing 4. The planet-pinions 9<a> gear with the sun-wheel 10 on the shaft 1. A plate 12 is mounted on the boss 3 so as to engage the sleeve 5, and carries sliding locking-members 14 adapted to engage notches 13 in the boss 6 of the pulley 7 and thereby cause the plate, the housing 4, and the pulley 7 to rotate together. A second plate 11 is mounted loosely on the boss 3 and is provided with inclined slots into which project pins 18 on the members 14. The pins also pass through slots 20 in the plate 12. Rotation of the plate 11 causes the pins 18 to move up or down the slots and so raises or lowers the members 14. The slots are so positioned that, when the members 14 are raised and the housing 4 is freed from the pulley 7, a pin 17 on the fixed bearing can pass into a slot in the plate 11 and lock the parts in position. The belt is placed on the loose pulley, whilst the plate 11 is being turned to reverse the direction of the drive.

Title: Improvements in or relating to absorption refrigerating apparatus
IPC: F25B37/00
Filed: 1932-03-24
Abstract: 382,867. Refrigerating. HOOVER, Ltd., Perivale, Greenford, Middlesex.-(Assignees of Nelson, R. S. ; 1020, Crosby Street, Rockford, Illinois, U.S.A.) March 24, 1932, No. 8771. Convention date, April 2, 1931. [Class 29.] Absorption systems.-In continuous-cycle apparatus having a cooling system for the absorber A or other element of the apparatus comprising a jacket 30 or equivalent pipe coils supplied with refrigerant from the condenser C through pipe 49 which is preferably finned, the portion of the refrigerant vaporized by the absorption of heat from the absorber A rises to a gas separating chamber 51 carrying with it the unvaporized portion, the liquid refrigerant leaving this chamber through pipe 53 to the evaporator E and the gas returning to the air-cooled condenser C to be recondensed. Both the evaporator E and absorber C are provided with central passages 27, 32 to increase their heat exchange surface. The inert gas used in the system leaves the absorber A through a pipe 37 and absorbs heat from the gas returning to the absorber in heat exchanger 38. It then flows downwards through an air-cooled part of the pipe and, before it enters the evaporator E, imparts heat to the gas leaving the evaporator in heat exchanger 39. The gas that has been warmed in exchanger 39 is further heated in pipe 16 passing through the gas separating chamber S, air cooled in pipe 41, cooled in exchangers 38, 23 and returned to the absorber A. The changes in density produced by these heat exchanges assist the circulation of the inert gas which is further aided by a jet J supplied from the auxiliary boiler B2 through pipes 60, 63. The refrigerant expelled from the main boiler B1 is separated in chamber S, the liquid passing to boiler B2, while the gas passes to the condenser C to be liquefied and passed on to the evaporator as previously described. Pipe 66 is provided to allow liquid deposited in the gas circulation system to return to the absorber A.

Patent GB-754383-A (GB)
Title: Improvements in or relating to travelling wave tubes
IPC: H01J23/083
Filed: 1954-03-26
Abstract: 754,383. Travelling-wave tubes. WESTERN ELECTRIC CO., Inc. March 26, 1954 [April 3, 1953], No. 8910/54. Class 39 (1). The wave propagating circuit of a travelling- wave tube comprises a coaxial line 44, 45, Fig. 5, the inner conductor, along the interior of which the beam flows, being provided with a plurality of pairs of diametrically opposite slots 46, alternate pairs of slots being in the same circumferential positions and adjacent pairs of slots being displaced by 90 degrees so that the arrangement functions as an electrostatic focusing device for focusing the beam successively in different axial planes. It is shown that the system is equivalent to a " quadrupole " system of electrodes, Fig. 1 (not shown), and focuses the beam alternately in two mutually perpendicular planes, so that magnetic focusing means is not necessary. The number of slots around the circumference may be increased to obtain " sextipole " or " octopole " focusing. The circuit is particularly suitable for spatial harmonic operation in a mode having a positive or negative phase velocity, i.e. as a " forward " or " backward " wave amplifier, Fig. 5, or as a " backward " wave oscillator, Fig. 6 (not shown). The coaxial line conductors may be corrugated to slow up the wave. The analogy with prior art " quadrupole " magnetic focusing arrangements is discussed. In the form shown the slots 47 are rectangular and of equal size; their length is slightly less than the axial spacing between adjacent pairs of slots which spacing is small compared to the operating wavelength. The inner conductor 44 is positive with respect to outer conductor 45 and the slots 47 in the inner conductor each extend over about 90 degrees of the circumference. The mathematical conditions for synchronism are given for " forward " and " backward " waves of the first spatial harmonic modes. For " forward " wave amplification a coating of loss material, e.g. colloidal graphite, is provided on either of the coaxial line conductors. In a backward wave oscillator, Fig. 6 (not shown), the downstream end of the line has a reflectionless termination inside the tube comprising an annular wedge of dielectric material coated with lossy resistive material. In such a tube the frequency depends on the beam velocity so that if a signal source is connected between the cathode and the inner conductor of the line a frequency modulated output is obtained. The shapes of the line conductors and slots may be modified if desired.

Title: Parachute Equipped Aeroplane.
Inventor: UTTZ WILLIAM ANDREW
IPC: B64D25/08
Filed: 1918-06-01
Abstract: 116,498. Uttz, W. A. June 1, 1917, [Convention date]. Parachutes. - A parachute carried in a container under the fuselage of an aeroplane is connected to a detachable seat for the pilot in such a way that, when the parachute is released and allowed to open, the seat is drawn rearwards and downwards free of the machine. The container 19, Fig. 4, is carried by a movable section 7 hinged at 8 underneath the fuselage and normally held secured to the fuselageby a catch 9. The seat 3 is mounted on inclined rails 13 and normally rests on a projection 5 on the fuselage and a cross-bar 6 on the section 7. The parachute comprises smaller and larger members 41, 39, Fig. 3, connected together by cords 51, 52, the cord 40 of the larger member being connected by a link 26, Fig. 6, to a carriage 23, which runs on a track on the container 19 and is further connected bv a link 25 to a cord 26<a> which normally passes round a pulley 27, Fig. 4, on the section 7, and is attached bv a bail 15 to the seat. The smaller parachute 41 is of umbrella type opened by a spring 46, Figs. 6 and 7, and is normally held in the container, against the pressure of springs 50, by a cross-bar 48 engaging bayonet-slots in the opposite sides of the container. The bar 48 is released from these bayonet-slots by movement of a yoke 33 formed at opposite sides of the container with reversely inclined slots 34, the yoke being actuated by means of a cord 35 connected to a hand-lever 37, Fig. 4, near the pilot. When the parachute 41 is thus released, it is forced out of the casing by the springs 50 and opened by the spring 46, drawing out the larger parachute as shown in Fig. 3. The carriage 23 is thus drawn rearwards, so that the cord 26<a> becomes taut and pulls the seat rearwards and downwards, at the same time releasing the catch 9 and allowing the section 7 to fall, as shown in Fig. 4.

Abstract: 1,218,723. Compressors. TECUMSEH PRODUCTS CO. Feb.20, 1969 [Feb. 21, 1968], No. 9137/69. Heading F1N. A motor-compressor unit 18 resiliently mounted in a sealed housing 12, 14 comprises a piston 38 reciprocated in a cylinder 40 by a crank 32 disposed in a crank-case 44, the crank-case being vented to the housing 12, 14 through passages so directed that gas pulsations therethrough, produced by the piston reciprocations, tend to reduce vibration of the unit. The cylinder 20 and crankcase 44 are formed as an integral casting, Fig. 7, the vent passages 500, (502) being disposed at the intersection between the top wall 50 and the side walls. Thus, gas passes obliquely through the passages, and the forces 504, 505 due to such flow are arranged to resolve into two vertically upward components 506, 508 and two components 514, 516 directed parallel to the cylinder axis in a direction towards the cylinder. The vertical components 506, 508 tend to balance forces due to the downward suction flow in intake pipes 70. The other two components tend to balance the reaction forces of gas acting on the low-pressure side of the piston. The vent passages may be completely in the crankcase side walls, Figs.3 and 4 (not shown), or completely in the top wall, Fig. 5 (not shown), whereby only selected vibration forces are balanced.

Abstract: 728,294. Forging; rolling. ELMEG ELEKTRO-MECHANIK GES. April 9, 1952 [April 9, 1951], No. 9149/52. Classes 83 (2) and 83 (4). A process for manufacturing pressed parts consists in that the metal to be treated 13 is held between electrodes 11, 12, heated wholly or in part by resistance heating to a point slightly below melting point, released and immediately shaped thereafter by impact. The part 13 is dropped into a die 14 by lateral movement of the electrodes which switches on the current to energize the impact coil 3, thus causing the die 10 to descend and shape the part. In a modification, the electrodes hold an elongated workpiece with its axis in the direction of die movement and are then respectively raised and lowered and swung clear of the dies as these are relatively moved. In a further modification, the electrodes may be carried on discs 51, 56, Fig. 5, and the dies also carried on rotary discs. One or more dies may be arranged to act at the same time. For producing needlebearings and screw threads, a part 81, Fig. 8, may be acted on by grooved dies 85, 86. Yet again, an electromagnetically operated plunger 90, Fig. 9, may force a heated part 89 into one or more dies 94 through one or more passages 93.
