Patent GB-564619-A (GB)
Title: Improvements in or relating to key-operated digit transmitting apparatus
Filed: 1943-03-31
Abstract: 564,619. Card punching systems. BRITISH TABULATING MACHINE CO., Ltd. March 31, 1943, No. 5191. Convention date, April 1, 1942. [Class 40 (i)] [Also in Group VIII] In a system for setting up multi-digit numbers with different numbers of digits from a single keystrip, each digit is first registered on the units register, each operation of a key after the first causing the digits so far registered to be transferred to the registers of the next higher order (units to tens, tens to hundreds, and so on). By this means the number can be keyed from left to right in the ordinary way without initial zeros to ensure registration of the digits in their proper places. The invention is described with reference to the control of a card punching machine of the kind described in Specification 362,529, [Group VIII]. In the drawings, the same relay may be shown in full lines in its energizing circuit and in dotted lines in various other positions adjacent certain of its contacts. Circuit operations. Operation of a digit key energizes the corresponding relay KC1 ... KC9 and completes a common circuit for a group of sequence controlling relays R1, R1<1> . . . R5. These relays operate in succession as indicated in Fig. 2, and remain operated while the key remains depressed and then fall in succession. The cycle is completed even if the key operation is very brief since the common key-actuated contact is shunted by a circuit closed by R1 and opened by R5. The digit relays complete circuits over one or more of four leads for the units group of register relays 101 ... 104, in the auxiliary or A section of the registering equipment. On the operation of R3, R3<1>, the relays 103-308 of the main or B section are unlocked and the setting of the A units register is taken up by the B units register. The A register remains locked until the next operation of a key, whereupon it takes up the new setting. On the operation of R1<1> the setting of the B units register is taken up by the A tens register. On the operation of R3, R3<1>, the B registers are cleared and the units and tens registers therein take up the setting of the units and tens A registers. On the depression of another key, the setting of the B units and tens registers is transferred to the A tens and hundreds registers and then the B register takes the setting of all three A registers. A number is then entered on an additional register set providing for a maximum of five digits, a key 120 being operated first, to cause the momentary operation of R11 which energizes R12, which locks. When the number has been registered, the key 120 is operated for a second time to operate R13 which initiates the transfer of the registered digits in turn to the punching magnets of the machine. When the machine completes its operation, all relays are unlocked. If a key is pressed while the punching machine is in action, a buzzer is sounded. If fewer than the maximum number of digits are keyed, the machine punches zeros for the unoperated registers.

Patent GB-608532-A (GB)
Title: Improvements in centre weft-fork stop-motions for looms for weaving
IPC: D03D51/34
Filed: 1946-02-26
Abstract: 608,532. Centre weft-fork stop-motions. BLOMFIELD, M. A. Feb. 26, 1946, No. 5938. [Class 142(i)] A centre weft-fork stopmotion is characterized in that when the loom is running with weft the slide A that is mounted on the front of the sley and receives a reciprocating endwise movement through a connection with a fitting on the breast rail, has its movement curtailed in one direction by a stop B thereon abutting against a downwardly-extending tongue D on the tippler C which carries the weft fork prongs E. When such movement of the slide is arrested, the incline thereon engages a finger on the tippler so that the weft fork is lifted at the beginning of the return movement of the slide. When the weft fork is unsupported by weft the tongue D moves out of the way of the stop B so that the slide continues its movement until arrested by a stop G abutting against one end of the bracket K in which the slide is mounted. The slide during its continued movement moves a slotted stationary member U<SP>4</SP> which in turn moves a pin J<SP>1</SP> on a lever J so as to knock the spring handle out of its starting position and actuate a brake to stop the loom. The movement of the slide in the reverse direction is arrested by an adjustablymounted stop H abutting against the other end of the bracket K. The slide is reciprocated by means of a rod M which is frictionally-operated through a plate O<SP>2</SP> attached to the rod and subjected to pressure between two cork or other frictional pads P mounted in a holder S pivoted on the breast rail. If the loom is required to run when the weft fork is unsupported by weft, the member U<SP>4</SP> is raised until it rests on a projection V on a displaceable lever V' in which position the pin J' is free to move in the slot in the member U<SP>4</SP>

Title: Improvements in or relating to shock absorbers
IPC: F16F9/26
Filed: 1945-03-12
Abstract: 589,453. Shock-absorbers. VANDERVELL PRODUCTS, Ltd., and JOHNSON, E. W. March 12,1945, No. 6163. [Class 108 (iii)] In a double-acting shock-absorber in which a restricted passage for the flow of damping fluid in both directions between two fluid containers 28, 29 is provided between the opposed surfaces of a metering rod 94 and a bore 32 into which the rod 94 reaches and in which a bye-pass is provided through the interior of the rod 94, travel of fluid through the bye-pass in each direction is controlled respectively by one of two valves 115, 116, operated by the pressure of the fluid. In the construction shown in Fig. 1, the metering rod 94 passes through a sleeve 32 located in the main piston the heads 30, 31 of which reciprocate respectively in the containers 28, 29. A conduit 112 permits fluid to pass in both directions between the container 29 and the interior of the rod 94 and conduits 113, 114 in the opposite end of the rod 94 co-operate with the valves 115, 116 to control the flow of fluid respectively to and from the container 28. The valve 115 is slidable upon the valve 116, a single spring 117 urging both valves into a position to isolate the conduits 113, 114 from the container 28. A predetermined pressure in the container 28 uncovers the port 114 by acting against the right-hand end surface of the valve 116 which is designed to have greater area than its area exposed to pressure from the opposite direction. A predetermined pressure in the container 29 acts through conduits 112, 113 against the end wall of a recess 120 in the valve 115 to open the conduit 113 to the container 28. The valve 116 has longitudinal clearance grooves 119 to prevent turbulence and both valves may have their bores enlarged in the region of their associated conduits so that full flow will occur with a minimum valve opening thereby avoiding valve chatter. In a second construction the metering rod 94 is mounted in a separate casing formed in the wall of the casting of the main casing each end of which is connected by respective passages to the containers 28, 29. In a third construction, a separate spring is employed for each of the valves 115, 116. Fluid in the containers 28, 29 is replenished from a recuperator chamber 16 through ball-valve-controlled passages 121, 122 which are arranged at right angles to the surfaces of the coned inner portions of the piston heads 30, 31 in such manner that each of these passages can be drilled through from the open end of the recess in the piston head. Each ball 123 is retained in its passage by a forcefitted castellated bush 125, and tends to fall by gravity on to its conical seat. The general construction is similar to that described in Specification 548,011. Specifications 541,179 and 541,201 also are referred to.
