Title: Improvements in Gear Shift Mechanisms for Change-Speed Gear Boxes
IPC: F16H63/18
Filed: 1967-01-24
Abstract: 1,165,993. Change speed control. ROBERT BOSCH G.m.b.H. 24 Jan., 1967 [25 Jan., 1966], No. 3520/67. Heading F2D. In a gear-shift mechanism, particularly for motor vehicles, wherein a cross-shifting cam and a gear-establishing cam are simultaneously rotated by an electric motor, the cross-shifting cam extends substantially in the form of a helix or spiral each convolution of which corresponds to one gearestablishing element, and the gear-establishing cam has a continuous contour extending 360 degrees. In Fig. 1, the cross-shifting and gear-establishing cams comprise grooves 15, 21 respectively in the periphery and an end face of a cylinder 14 which is driven by a reversible electric motor 13 through reduction gearing in a casing 12. The groove 15 comprises three circumferential portions 16 (reverse), 17 (1-2), 18 (3-4) connected by helical portions 19, 20. The groove 15 is engaged by a pin 26 extending through a slot in a bearing block 24 from a rod 27 longitudinally displaceable in said block. The groove 21 is substantially oval and is engaged by a roller 22 carried by an arm 23 mounted on a hollow shaft 25 rotatably mounted in the block 24. A fork 28 carried by the rod 27 and extending through slots in the block 24 and the hollow shaft 25 engages an annular groove 29 in an actuating rod 30 so as to transmit longitudinal movements thereto. Pivotal movements of the hollow shaft 25 are transmitted to the rod 30 by a cross-pin 31 extending through the latter and engaging longitudinal slots 32 in the hollow shaft. The rod 30 is connected to a gear-box actuating rod moving in accordance with an H - shape with one side branch to provide four forward ratios and one reverse. The two helical groove portions 19, 20 effect axial cross-shifting movement of the rod 30 when the arm 23 is midway of its gear-establishing movement, i.e. in Neutral. In Fig. 3, the ends of the cross-pin 31 selectively engage axially extending grooves 53, 54, 55 in hubs 50, 51, 52 of pivotal arms 46, 47, 48 which are connected by rods to gear-establishing levers (40), (41), (42) pivotally mounted on a gear-box. Since the hub 50 serves only for reverse, the groove 53 therein is made wider to provide circumferential lost motion, so that, with a gear-box in which 1st and reverse are engaged in the same direction, shift therebetween may be effected by a full revolution of the cylinder 14 without interruption. In an alternative embodiment, wherein for cross-shift and gear-establishment a member is respectively rotated and axially shifted, the cross-shift and gear-establishing cams respectively comprise a spiral end-face groove and a peripheral groove which latter may have a centre position detent or notch.

Abstract: 991,285. Spraying fusible materials. F. W. BERK & CO. Ltd. Feb. 1, 1962 [Feb. 1, 1961], No. 3816/61. Heading B2F. In a pistol for spraying fusible materials wherein the material is conveyed to the pistol outlet by a conveying gas, fused in a flame and sprayed from the pistol by a projecting gas, valve 5, Figs. 1 and 4, is provided whereby when the pistol trigger 9 is operated to stop the flow of projecting gas through the pistol the supply of a material supplying gas and hence the material is thereby indirectly cut off. The material may be in powder form fed from a hopper 2 into a conveying gas stream in pipes 3, 4, or it may be in wire or strip form (not shown), the conveying gas actuating a turbine to advance the wire to the spraying nozzle. The cylindrical valve assembly 5, Fig. 4, has a conveying gas inlet 12 and outlet 13, projecting gas inlet 14 and outlet 15, and piston heads 16, 17. In operation the piston head 17 lies in chamber 11 and head 16 in chamber 10. When the trigger 9 is operated to stop the flow of the projecting gas through the pistol the projecting gas pressure on piston head 17 builds up and overcomes the opposing pressure of conveying' gas on head 16 so that the piston slides to close inlet 12 and stops the flow of conveying gas to pipe 4 and hence stops the supply of material to be sprayed.

Title: Improvements in or relating to gas detection method and apparatus
IPC: G01N27/416
Filed: 1954-02-11
Abstract: 776,770. Electric tests. MINE SAFETY APPLIANCES CO. Feb. 11, 1954 [Feb. 26, 1953], No. 4024/54. Class 37. A cell for the electrochemical detection of the percentage oxidizing component (e.g. oxygen) of a gas mixture comprises a zinc electrode, and a carbon electrode whose surface is insulated except for a small window area, the gas being passed through a central bore of the carbon electrode to permeate through the untreated window area and react with a liquid electrolyte, producing an E.M.F. which is indicative of the percentage oxygen content of the gas mixture, and is measured in a circuit giving a substantially linear response characteristic. Cell construction.-The cell container 1 (Fig. 1), of insulating material contains a liquid dielectric, a zinc electrode 3 supported by a stainless steel rod 4, and a carbon electrode 5 whose external surface is coated with enamel 5b except for recessed windows 6, which may be one to four in number depending on the percentage oxygen content to be measured. The gas is passed through a hole 5a running through the middle of the carbon electrode 5, the gas and the liquid electrolyte diffusing through the window 6 of the carbon rod 5 to give an output voltage dependent on the percentage oxygen content. The liquid dielectric is a 2-5 per cent solution of ammonium chloride with hydrochloric or sulphuric acid added to a pH of 3.0. Measuring circuit.-In one embodiment (Fig. 14), the output current of the cell 1 is made proportional to the percentage oxygen content by backing off the current at zero oxygen content with an auxiliary battery 16, which produces a substantially constant P.D. across the tapped-off part of a potentiometer 17 to oppose the zero current, whereupon the current shown in meter 22 is made substantially proportional to the oxygen content of the gas passing through the cell 1 by a predetermined choice of circuit component values. In another method using the same circuit and based on the fact that the percentage oxygen content is proportional to the electrical power developed, the voltage on meter 27 and the current on meter 22 are made constant by adjustment of potentiometers 17 and 21, whereupon the oxygen content is proportional to the current in the auxiliary circuit as indicated by meter 25. The circuit may also include an adjustable shunt resistor 28 (Fig. 11), across the auxiliary battery 16 to simulate the ageing of the cell 1, and a zero adjusting circuit 31 which supplies a small zeroizing current through the meter 22. Specifications 749,147 and 776,771 are referred to.
