IPC: B62D11/08
Filed: 1961-12-12
Abstract: 932,334. Change-speed gear. GENERAL MOTORS CORPORATION. Dec. 12, 1961 [Feb. 24, 1961], No. 44409/61. Class 80 (2). [Also in Group XXXI] A transmission, especially for driving and steering an endless track tractor, comprises an input shaft and two output shafts which are connectible by a reverse gear whereby, when the drive shaft is disengaged from one output shaft and the reverse gear connects the output shafts, the latter are rotated in opposite directions. The input shaft 10 drives through gears 11 and 12 a cross shaft 14 which drives a ring gear 16 of a planetary gear set whose planet pinions 18 are rotatably mounted on a carrier 19 and mesh with a sun gear 21, the carrier 19 being connected to an output shaft 22. The sun gear may be braked by a brake RL to establish a low gear in the planetary gear set and is connectible to the output shaft 22 by a clutch RH to establish a direct drive in the planetary gear set, so providing a second gear ratio. The output shaft 22 is connected through the carrier 19 to a vehicle brake RB. The shaft 14 is also connected to a ring gear 36 of a planetary gear set whose planet pinions 32 are rotatably mounted on a carrier 33 connected to an output shaft 34 and mesh with a sun gear 37 brakeable by a brake LL to establish a low gear and connectible by a clutch LH to the output shaft 34 whereby a direct (high) gear ratio is obtained. The output shaft 34 is connected by the carrier 33 to the vehicle brake LB. The shaft 22 drives a shaft 53 through pinions 51 and 52 and the shaft 34 drives a shaft 61 through pinions 56, 57 and 59. The shafts 53 and 61 drive, through pinions 63 and 66 respectively, spur gears 64 and 67 connectible by a clutch D and rotatable about shaft 14. The transmission may be operated to provide forward low speed or high speed drives by engaging clutches LL and RL, or LH and RH, respectively, brake steering being possible by disengaging the gear and braking on that side and pivot steering in either gears being obtainable by engaging the gears on one side, disengaging the gears on the other, and engaging the clutch D. In a modification, Fig. 2, the gears 63, 64, 66 and 67 are omitted and the shafts 53 and 61 are connected by a clutch D<SP>1</SP>. In a second modification, Fig. 3, the output shaft 22 is connectible to a spur gear 74 by a clutch D<SP>11</SP> mounted in its hub, the gear 74 meshing with a pinion 73 connected by a shaft 72 to pinion 59.

Title: Improvements relating to non-linear electrical resistance elements
Inventor: JOHNSON FREDERICK LAWRENCE
IPC: H01C7/118
Filed: 1961-12-15
Abstract: 1,037,822. Non-linear resistors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 12, 1962 [Dec. 15, 1961], No. 45032/61. Heading H1K. A resistance element consists of an electrically insulating lamina containing a single layer of particles of non-linear resistance material each of which projects from both faces of the lamina to engage electrodes at said faces. The granules may be spread in a single layer on a polythene lamina and then pressed into it or a polythene lamina and a layer of granules may be sandwiched between sheets of rubber and the sandwich heated under pressure so that the polythene deforms to leave the granules projecting from its surfaces. In a further method described a layer of granules is held under pressure between two rubber surfaces, a resinous material introduced around the granules by vacuum impregnation, and the rubber surfaces removed after solidifying the resin. The resinous material may, however, be mixed with the granules, then solidified whereupon opposed surfaces of the lamina so formed are teased or ground to expose the granules at these surfaces. A composite lamina with projecting granules may be produced by applying pressure to abutting laminµ with a layer of granules in an adhesive layer between the faces. In one embodiment (Fig. 1) a layer of granules of silicon carbide 1 embedded in a lamina 2 is contacted by opposing rigid conductive plates 3a and 3b separated by an insulating washer. A second embodiment (Fig. 2, not shown) utilizes two conical washers which insulate two rigid conductive discs in contact with the granules from a centrally disposed bolt passing through the discs and forming with them a composite unit. A third embodiment utilizes an insulating lamina in strip form (Figs. 3 and 4, not shown) with granules embedded in a central longitudinal portion of the strip and conductive connection to the granules provided by a conductive coating. Any form of the non-linear resistance elements disclosed may be encapsulated in a suitable resin.

Title: Improvements in or relating to Radiation Scanning Recorders.
Inventor: WOLLER PETER
IPC: G01T1/166
Filed: 1966-10-10
Abstract: 1,151,758. Counting apparatus. MEDIZINISCHE AKADEMIE " CARL GUSTAV CARUS." 10 Oct., 1966, No. 45174/66. Heading G4D. [Also in Division H4] The invention relates to a system for plotting simultaneously a plurality of scintigrams with different degrees of contrast amplification. In the Fig. 1 embodiment, radiation from a radioactive tracer selectively stored in body tissue of a patient is detected by a scintillation counter SZ feeding output pulses (at a variable rate I s ) to forward-counting inputs v of divideby-ten counters ZD. Pulses at a rate I M  are produced by a generator MG, divided down to <SP>1</SP>/ 12 , <SP>2</SP>/ 12 , <SP>3</SP>/ 12  and <SP>4</SP>/ 12  of this rate and then applied to adding stages A together with pulses from a generator NG at the radiation background rate IN. The different summation pulse rates from stages A are applied to reversecounting inputs r of the counters ZD. Counters ZD thus produce output pulses with respective rates (I S -I N )/10; (I S -I N -4I M /12)/10; (I S - I N -3I M /12)/10; (I S -I N -2I M /12)/10 and (I S -I N -I M /12)/10 and control printing mechanisms DW which thereby print symbols with a density representing radiation intensity. The printing mechanisms DW are scanned over a recording medium in synchronism with scanning of the scintillation counter SZ over a region under examination. In an alternative embodiment (Fig. 2) the counter SZ pulses, after rate-division by a constant, pass through a delay stage (V<SP>s</SP>) and charge up a capacitor (C) in parallel with a resistor (R). The capacitor voltage controls a plurality of Schmitt-trigger stages (ST) which have different threshold values and when in their triggered state open gates (To) to feed the rate-divided pulses through further rate-dividers to the corresponding printing mechanisms DW. The output pulse rate appearing at each printer will thus be a function of the counter SZ pulse rate, the function being different for each printer due to the different Schmitt threshold values and to the statistical distribution of the counter SZ pulses. In either embodiment the number of pulses fed to the printing mechanisms DW is effectively increased for high pulse rates from counter SZ and decreased for low pulse rates, thus providing the contrast amplification.

Abstract: 1,184,959. Folding and finishing edges of non- metallic sheet material. PODOLSKY MEKHANICHESKY ZAVOD IMENI M. I. KALININA. 4 Oct., 1967, No. 45213/67. Heading B5K. The edge of a leather workpiece is treated by advancing the workpiece while the flesh side of the leather is in contact with a heating tool 6, intermittently halting the advance of the workpiece and pressing the tool 6 into the workpiece so as to pierce the workpiece. As shown, an edge-folding machine comprises an electrically-heated tool 6, a clamp 7, a hammer 10 and a mechanism for intermittently feeding the workpiece comprising a toothed rack 24 and a plate 25. The workpieee is placed with its grain side down on a platform 1 and is brought under the tool 6. The drive to the main shaft 5 of the machine is started and the rack is moved in an elliptical path by a combination of a vertical reciprocation, imparted through shafts 5, 38, 37, 36, a cam 35, a connecting rod 33, a crank 34, a shaft 32 and a fork 31, and an oscillating movement, imparted through shafts 5, 38, 37, 36, 27. Simultaneously, the plate 25 is reciprocated by shafts 5, 38, 37, 36, 27, a crank 26 and a lever system. The tool 6 is mounted so that its pointed end lightly contacts the flesh side of the leather edge to cause its partial contraction. During the intervals in which the workpiece is stationary the tool 6 descends and pierces the leather to cause the flesh side of the leather to contract and the grain side to rise. The reciprocation of the tool 6 is effected by the shaft 5, a cam 19, a connecting rod 20 and a rod 21 attached to jaw 22, 23 holding the tool 6. To hold the workpiece at the moment of piercing, the clamp 7 is lowered simultaneously with the tool 6 by the shaft 5, a cam 12, a lever 18, a shaft 16, a crank 15, a connecting link 14, a lever 13 and a rod 11. The rack 24 and the plate 25 then return to their initial position. As the workpiece is advanced further the raised grain side is pressed over on to the flesh side of the leather by the hammer 10 which drops simultaneously with the rack 24 through cams 30, 35 on the shaft 36.

Abstract: 1408472 Fishing gaff B JOHANSSON 27 Sept 1973 45359/73 Heading A1A A gaff for removing caught fish from the water comprises a yoke 3 integral with a limb 1 and pivotally attached to a second limb 2. Spears 11 are pivotally secured to the limb 1, each spear having a shoulder 14 which holds it at an acute angle to the said limb and inclined towards the yoke 3. A locking yoke 15 pivoted on the limb 2 may seat in one of a number of grooves in the outer edge of the limb 1, to hold the limbs at a preselected angle to each other, the rotary motion of the pivoted limb being hindered owing to the pressure exerted on the yoke 3 by the 'bolt 8. In use, the device is lowered over the body of the fish causing the spears to fold against the fixed limb 1. On raising the gaff, the weight of the fish causes it to become impaled upon the spears after which it can be lifted from the water. The limbs may be folded together for transit, in which case the spears are located in a protective longitudinal groove 18 in the pivotal limb 2. The number of limbs may be extended to more than two and the spear bearing limb may also be pivoted to the yoke. In addition, each spear may be spring held in its operative position.
