Abstract: 506,972. Hydraulic transmission of power. GENERAL MOTORS CORPORATION. July 8, 1938, No. 20256. Conventiondate, July 16, 1937. [Class 69 (ii)] [Also in Groups XXXIV and XXXI] A master cylinder comprises a return spring so mounted that the mechanical advantage of the operator's foot against it increases as the plunger is depressed thus ensuring that the resistance to the operator's foot does not increase. The spring 59 is coiled round the connecting pivot 53 of two links 49, 43 pivoted to the master cylinder pedal 37 at 47 and a fixed point 41 respectively. The ends of the spring are each hooked round a link. Each link is fixed to one part of the pivot 53 which is in two parts having notch and lug engagement, in order to prevent alignment of the links and locking of the piston in the outermost position. In a modification this is prevented by an extension of the pivot 53 which is adapted to engage the piston 23. The piston 23 is guided in guides 21, 67 and a packing sleeve 77. A check valve 91 allows liquid to be drawn from the reservoir into the cylinder by the suction created on brake release. This liquid is returned through passages in the end of the piston which register with passages 71, 103 in release position. Passages 103, 69 supply fluid to the space behind the piston.

Title: Means for piston-skirt lubrication in reciprocating engines
IPC: F16J1/08
Filed: 1965-05-13
Abstract: 1,096,646. Bearings; lubricating; pistons. HEDEMORA VERKSTADER A.B. May 13, 1965 [May 13, 1964], No. 20350/65. Headings F2A and F2T. The amount of lubricant which is supplied to a space formed between a piston skirt and the wall of a cylinder in which the piston moves, is controlled by a temperature-sensitive valve so that, as the temperature rises to a predetermined temperature, the flow of lubricant is reduced or terminated. In an embodiment, a piston 11, Fig. 1, is mounted in a cylinder liner 10 and has a transverse bore therein which receives a piston-pin 12 having a connecting- rod 13 journalled thereon. A disc 17, having a peripheral groove 8 which receives a sealing ring 20 therein is mounted at each end of the transverse bore of the pin 12. Each disc 17 is retained by a snap-ring 18 and has radial recesses 9 therein. The pin 12 has four circumferentially-spaced bores 14 which are supplied with pressurized lubricant from a passage 15 in the connecting-rod 13 and has radial bores 16 therein which convey lubricant to the bearing surfaces of the pin and its bore. Lubricant is also conveyed from the bores 14, through axial passages 21 in the pin 12, through a gap 19, Fig. 2, in the sealing-ring 20, to a space formed between the disc 17, Fig. 1, a cylindrical liner 10, a piston-ring 22 and a piston-ring 23. Passages 7 and 24 in the piston dissipate excess pressure and lubricant respectively. As the engine temperature rises after starting, the sealing-ring 20 expands and the gap 19 is reduced, thus decreasing the flow of lubricant therethrough. In modifications, each disc 17 has no sealing-ring, is made of material such as P.T.F.E. and expands to seal the bore when the temperature reaches the required limit; each disc seals the bore, has holes therethrough which coincide with an annular groove therein which receives a splitsealing ring; each disc has an axial bore which, when the engine temperature rises, is closed by one end of an expandable rod; and plugs, having an axial bore therein, are mounted at each end of the bore of the pin, the axial bore of each plug being blocked by an expandable rod when the temperature rises a required amount.

Title: Null dependent symbol recognition
IPC: G06V30/192
Filed: 1962-05-28
Abstract: 973,429. Automatic character reading. SPERRY RAND CORPORATION. May 28, 1962 [June 5,1961 No. 20421/62. Heading G4R. In an automatic character reader characters are sensed to produce a characteristic waveform which is sampled e.g. in a tapped delay line 7, Fig. 1, and the samples applied in parallel to correlation circuits 10a-10n designed so that positive and negative peaks of the waveform are interconnected through resistors so as to produce a balance or null condition when the corresponding character waveform is applied. The interconnections are made twice as shown in Fig. 3 for the "0" wave, Fig. 2C, one set being connected through diodes 50-61 to a positive lead 46 and the other through diodes 64-75 to a negative lead 47. Any out-ofbalance will produce a non-recognition signal. In addition the tapping C, which at the instant the character is properly registered, should be at zero potential is connected through resistors 51, 65 and diodes 52 and 66 to the two output leads. An appropriate characteristic waveform produces a null output on both leads, or at least a minimum signal. The signals on each pair of leads are combined in an amplifier 11a-11n and applied as a positive signal to a comparator. The other input comes from a variable gain amplifier 20 connected via diodes 19 to each output, the diodes being biased by a battery so that the signal nearest to zero passes to the amplifier 20. One of the comparators 12a-12n produces an output which identifies the character. If more than one output is produced a circuit 21 responds to pass a signal to gate 22 which normally applies an enabling signal to gates 13a-13n. The signal from unit 21 closes these gates and blocks the output. If the gates are open the signal identifying the character is applied to a delay 14a-14n device comprising an integrator. these cause short spurious pulses to be ignored. When the output of one of the units 14a-14n reaches a certain level a mono-stable unit 15a-15n is set to give an output on one of the final output leads Lo-Ln. If there is already an output on one of these leads circuit 23 causes the gating signal from gate 22 to be blocked. Another circuit responds if a character identifying signal does not appear at the correct time in a succession of signals to indicate that a character has passed unrecognised.

The slide supports the tool assembly 16 which has two tool holders 17, 18 arranged to be brought alternately into engagement with the blank by movement of a lever 22 on a shaft 21 of the assembly effected by a cam 25 driven by gearing 26, 27 and a chain drive 28 from a shaft 15 connected by gearing 13, 14 to the shaft 7. The cam moves the lever and shaft 21 so that during a first forward movement of the slide a coning or gathering tool mounted in the holder 17 forms a cone on the blank and during the second forward movement of the slide a finishing tool in the holder 18 forms a hexagonal washer head on the blank. The coning or gathering tool 102, Fig. 9, is slidable in the mount 17 and is urged into contact with the blank during the first forward movement of the slide by a part 110 engaged by a backing plate 85 on the assembly. The part 110 also engages a member 109 in turn engaging the knock-out 107 for the tool, the knock-out upsetting the end of the blank 101. As the slide is retracted, the knockout 107 is held stationary to prevent the blank being withdrawn from the die 19 by a lever 37 pivoted on the assembly and engaged by a roller 36 which is mounted on a member 40 and movable into engagement with the lever by a rod 55 connected by a bell-crank 45 and rod 41 to a cam 43 on the shaft 7. The roller moves against a spring-pressed lever 60 and its movement is adjustable by a tappet 53 on the bellcrank and an eccentric by which the rod 55 and member 40 are connected to the lever 60; a spherical bearing 56 permits the adjustment effected by the eccentric to slightly pivot the rod 55. After retraction of the tool 102 in mount 17, the assembly 16 is swung by the cam 25 to bring the finishing tool 124, Fig. 11, in the mount 18 into alignment with the blank, the knock-out 123 for the tool 125 forming a cylindrical recess 135 in the blank which is shaped with washer and hexagonal parts 131, 133 by the tool 124. During the retraction of the tool, the lever 37 for tool 124 engages the roller 36 to hold the knock-out 125 stationary and prevent the blank being withdrawn from the die 29. Specification 881,020 and U.S.A Specification 2,599,053 are referred to.

Abstract: 876,490. Electronic counting apparatus. ERICSSON TELEPHONES Ltd. June 25, 1959 [June 30, 1958], No. 20925/58. Class 106 (1). In a reversible counter comprising a series of cascaded multi-cathode counting tubes, means are provided to effect transfer additively or subtractively in a higher order tube when the discharge in the next lower order tube reaches one or other of two cathodes, the cathode which is effective in the lower tube being dependent on whether addition or subtraction is taking place. As shown, Fig. 1, a counter comprises multicathode tubes D1, D2, D3, and has an additive input A and a subtractive input S, the inputs being supplied with non-coincident positive pulses for addition and subtraction. On receipt of a pulse input, pulse modifying devices P1-P6 provided for each counting tube are adapted to step the associated tube additively (P1, P3, P5) or subtractively P2, P4, P6) respectively. The devices P3, P5 are connected to the "O" cathode of the respective preceding tubes and the devices P4, P6 are connected to the " 9 " cathode of the respective preceding tubes. The first additive input pulse at the terminal A is supplied to the device P1 to step the tube D1 and also to a thyratron T1 which is thereby fired to raise the potential of a line M thereby rendering the devices P3, P5 responsive on receipt of a transfer-representing input pulse to step their associated tubes additively. When the first subtractive pulse is supplied to the terminal S, it steps the tube D1 subtractively via the device P2 and also fires a thyratron T2 thereby cutting off the thyratron T1 which is cathode-coupled to the thyratron T2 and raising the potential of a line N to render the devices P4, P6 responsive on receipt of a transfer-representing input pulse to step their associated tubes subtractively. Various minor modifications of the circuit details are described (Figs. 2-4, not shown). Specifications 712,171 and 751,952 are referred to.
