Title: Improvements in or relating to counting devices
Inventor: ROBINSON TREVOR CYRIL VICTOR
IPC: G06M1/08
Filed: 1960-08-24
Abstract: 914,234. Counters. PRYOR & SON Ltd., EDWARD. Aug. 23, 1961 [Aug. 24, 1960], No. 29196/60. Class 106 (1). [Also in Group XXIX] A pneumatic device can be set to perform a predetermined number of operations. The predetermined number is indicated by a pointer registering with a scale plate, the pointer being manually rotated by a knob 5. In operation, the movement to be counted applies a pressure pulse to an inlet 28 to drive a piston 13 and piston-rod 12 to the right in Fig. 3, whereby a set of balls 18 are lifted over a ridge between adjacent grooves 19. At the end of the pulse constant air pressure from 34 returns the assembly slightly so that the balls 18 now engage the next groove and a rack 36 has rotated a pinion 37 one step. This proceeds until a port 2 in a plate 1 coupled to the setting knob engages with a port 4 so that further pressure pulses pass directly out of connection 50. Transfer and resetting. The connection 50 may be connected to the inlet of a like device to provide transfer to a higher denomination. Automatic resetting is effected by the supply of pressure air to connection 52. Various modifications are described.

Abstract: 468,175. Motor-vehicle transmission gearing. FORD MOTOR CO., Ltd. Oct. 27, 1936, No. 29201. Convention date, Dec. 2, 1935. [Classes 79 (ii) and 79 (iv)] [Also in Group XXXIV] In a motor vehicle, a solid propeller shaft of small diameter is supported by end and intermediate bearings in the torque tube. The torque tube 17 is rigidly attached to the flanged end of a bearing sleeve 12 formed integrally with one part of a conventional differential housing 10, a pair of spaced bearings 13, 14, in the sleeve supporting a shaft 15 with an integral pinion 16 driving the crown wheel 42 of the differential. The propeller shaft 21, connected to the pinion shaft 15 by a splined sleeve 20, is supported in a bearing 19 at the forward end of the torque tube and, intermediately therein, by a bearing 26. The bearing 26, Fig. 2, comprises an annulus of rollers 24 surrounding an enlarged portion 22 of the propeller shaft and enclosed by an outer race ring 23 with end packing rings 25. The race 23 is engaged by a sleeve 26 around which is vulcanized a resilient rubber ring 28-located by an shaped sheet metal sleeve 36 secured in position in the torque tube by spot welding. The sleeve holds the rubber ring 28 in compression, the bearing being assembled on a pilot and pushed in from the axle end of the torque tube, over a ridge 35 in the sleeve into a seating portion 34 and against a stop flange 33. Annular spaces are provided between the sleeve portion 34 and the torque tube and between the race ring 23 and the inner sleeve 26, an annular channel 29 being also provided in the rubber ring 28. Thus with radial intercommunicating openings 30, 31, 39, and an external fitting 38, the interior may be filled with lubricant.

Title: Selective and anti-parasitic system for the reception of constant frequency electro-magnetic waves or electric currents
IPC: H03G11/00
Filed: 1923-08-29
Abstract: 225,867. Marrec, Ltd., (Assignees of International Wireless Appliances Corporation), and Marrec, Y. Sept. 6, 1922, [Convention date]. Thermionic amplifiers and detectors; atmospherics and undesired signals, eliminating or limiting.-Relates to wireless-receiving systems of the type in which a group of aperiodic circuits is used for discriminating between signals and parasites, the desired signals being finally selected by means of another group of resonant circuits tuned to signal frequency. According to the present invention, the rectified output from an ordinarv receiver A is fed first to a group 1, 2, 3 of highly-damped amplifying circuits in which both signals and parasites are amplified simultaneously, without, however, their pitch being modified. The amplified currents are then fed to a series 4, 5, G of resonant circuits tuned to the note of the desired signals, or to a multiple or submultiple thereof. The filament temperature of these circuits is decreased to a point where (1) a limiting effect is imposed upon the parasites and (2) sustained local oscillation at signal frequency (autodyne) only sets in and persists during the period of the desired (signal. This ensures an intense reception of selected signals without " tailing," whilst the amplitude of atmospheric disturbances is relatively weakened.

Title: Improvements in and relating to methods and apparatus for corrugating metal tubes
IPC: B21C37/20
Filed: 1936-10-28
Abstract: 480,893. Making corrugated tubes ; spinning. LIVSEY, D. M. (Brinkman, L. H.) Oct. 28, 1936, No. 29278. [Classes 83 (ii) and 83 (iv)] A tube is corrugated by forming therein by rotary, exterior, lateral pressure a number of grooves, and subjecting the end wall of each groove successively to longitudinal pressure, while limiting the radial outward movement of the surface connecting said wall and the wall of the preceding groove. A tube P is progressively corrugated as it passes through the machine. In a sequence of operations, radial gripping jaws 110 engage the corrugations last completed, an annular groove is formed by tools 9, and tools 10 enter the groove last formed by the tools 9, whereupon the tools 110 release the tube and the head 7 carrying the tools 9, 10 is advanced by the distance between successive corrugations. The tools 110 again close on the tube, and the head 7 continues to advance, and a further corrugation is completed between the tools 10, 110. The tube is guided by an annular member 6a and by a guide S which serves as a clamping device which is used during the formation of the first set of grooves in the tube, before the automatic sequence of operations is commenced. The tool-supporting head 7 is secured to a hollow shaft 6 rotated through gearing 5g, 6g from a shaft 5, and is reciprocated thereon by oscillation of a pinion 59a engaging a rack 59t. The pinion is controlled by a rocker arm 59r actuated from a cam 58c on a shaft 58 which is driven through spur and worm gearing from the shaft 5. A cam 61c on shaft 58 moves a flanged sleeve 12 through levers 61, 62 against the action of a spring 12s, which carries surfaces 11, 11a engaging the ends of the tools 9, 10 to effect their inward movement, the tools being returned by springs 9s, 10s. The gripping-tools 110 are similarly controlled by a sleeve 111 reciprocated by a cam 158c through levers 161, 162. In a modification, gripping jaws 210, Fig. 6, carry pins 210a engaging in grooves 211b in an oscillating annulus 211a surrounding the support in which the tools are slidably mounted. The fixed position of the frame 103 supporting the gripping-jaws 110 and their associated mechanism, and the mean position of the sliding frame 4, are adjusted by rods 103r, 3r engaging respectively in projections 103s, 3s.

Title: Means for determining the brittleness of materials
IPC: G01N3/30
Filed: 1945-11-06
Abstract: 631,449. Testing physical qualities of materials. SCHNADT, H. Nov. 6, 1945, No. 29500. Convention date, May 27, 1942. [Class 106 (ii)] In brittleness tests, compression stresses in the test-piece in the region of rupture are reduced or obviated so that more accurate results are obtained. This is effected by boring or recessing the test-piece d, Figs. 7 and 16, at f opposite the section to be stressed, and either inserting a hard core therein, or shaping the knife or other stressing or impact member k at the end g to fit within the recess. Notches e of Charpy, Izod, or other form, may also be provided in the test-piece according to the apparatus to be used. It is stated that as during the process of rupture the instantaneous axis of rotation is in the core or in the end g, compression stresses in the test-piece are eliminated. In a modification, test-pieces such as thin metal plates or wires j, Fig. 19, are not notched, but are fitted on two-part supports m, recessed in each part to fit about a core g. The blow of the knife &c. c is applied opposite the core, and the test-piece breaks by rotating about the axis of the core. Instead of imparting an impulsive blow to the test-piece, the knife &c. may exert a slow, progressive force thereto.

Title: Rangefinder, rangefinder-sight, or sight of the overlapping-image type with image-distortion having no moving parts
IPC: F41G3/06
Filed: 1953-10-27
Abstract: 772,658. Range-finders. BEACONING OPTICAL & PRECISION MATERIALS, CO., Ltd. Oct. 27, 1953 [April 15, 1953], No. 29719/53. Class 97(1) [Also in Group XXI] A short home-base range-finder, giving two overlapping images has an optical distorting device comprising a pair of prisms 1, 2, angularly displaced relatively to one another about axis Z, in front of each or one of the objectives 5, so that two point images of a point on the target can be made to coincide in the field of view -of eyepiece 9. Preferably the prisms are chromatically corrected. As shown in Fig. 1, one of the overlapping images of a set of parallel straight lines may be distorted so that the separation D is varied progressively across the field of view or if two distorting devices are used (Fig. 5) both images may be distorted by equal or unequal amounts. The distance of the point of intersection of the images from a base line is a measure of their range and a scale in reticle 8 can be calibrated so that the range may be read directly. If the range-finder is to be used only as a sight for a firing weapon the relative rotations of the prisms 1, 2 are adjusted so that the range callibration fits the ballistic curve of the weapon and the range scale is then replaced by a single vertical hairline in order to train the weapon laterally.

Patent GB-841962-A (GB)
Title: Logical binary powering circuits
IPC: G06F7/552
Filed: 1957-09-24
Abstract: 841,962. Digital electric calculating-apparatus. SPERRY RAND CORPORATION. Sept. 24, 1957 [Oct. 8, 1956], No. 29944/57. Class 106 (1). In a logical circuit for obtaining a power (e.g. the square or cube) of a binary number, the number is entered in an input register, intermediate storage registers receive from the input register, at a set of spaced stages, electrical signals representing the digits of the number and, at another set of stages, electrical signals representing the logical combination of different digits, and an adder combines digit representing signals from the intermediate storage registers, the output of the adder representing the power of the number. The circuit shown produces the square of a 4-digit binary number abcd set up on bi-stable flip-flops of input register 10. The " 1 " outputs of the flip-flops are applied through clock-pulse-controlled gates 7a-7d to lines a, b, c, d which are connected as indicated directly and through coincidence gates 17-21, to certain of the flip-flop stages of intermediate storage registers 15 and 16, to cause these stages to be set when the values of the corresponding digits are " 1." The connections correspond to the coefficients of different powers of 2 for the squared number (a23 + b2<SP>2</SP> + c2<SP>1</SP> + d2<SP>0</SP>)<SP>2</SP>. Thus, e.g. the coefficient of 2<SP>0</SP> will be d<SP>2</SP> = d which is entered in the lowest stages of register 15, and the coefficient of 22 will be C<SP>2</SP> + cd, the factors c and cd therefore being entered in corresponding stages of 15 and 16. In the case of 2<SP>4</SP> only, there are three coefficient factors b, bc and ad, which cannot all be entered directly in the two registers; the factor ad is entered in register 16, but the factors b and bc are first combined in half-adder 23 whose sum and carry outputs are applied to adjacent stages 25, 27 of register 15. Alternatively, coincidence gates may be connected to cause these stages to respond to #bc and bc respectively (where c indicates c = o). After the factors have been entered in registers 15, 16, further clock-pulse-controlled gates 8a-8g and 9a-9g cause the register contents to be passed simultaneously to parallel adder 28 which then supplies the required square at its outputs. In a similar circuit (Fig. 2, not shown) for squaring a 6-digit number, the factors are stored in three intermediate registers and the parallel addition is performed in two successive steps. In the case of an odd number of digits, the square has an extra factor in three places (instead of one), these factors being dealt with by additional logical circuitry associated with one of the intermediate registers (Fig. 3, not shown). In general, to obtain the square of an N-digit number, K intermediate storage registers and K-1 parallel additions are required, where K = N/2 when N is even and K = N-1/2 when N is odd. An arrangement employing three intermediate registers for finding the cube of a 4- digit binary number also is described. Reference is made also to finding higher powers.
