[Also in Division H2] In apparatus comprising an indicator 33, 34 of the rate of travel of a motor vehicle and an indicator 20, 21 of its engine speed, gearing 7, 8, 9,10 in the transmission from the engine is so chosen that at the optimum or maximum permissible speed of the engine the pointer 20 indicates one hundred per cent on the scale 21 which is adapted to indicate ratios between actual and optimum or maximum permissible engine speed. As shown in Fig. 3, the dial 21 and central area of chart 22 are graduated in percentages from 70 to 120, the lower range being suppressed by prestressing the return spring 14 acting on the eddycurrent bell 13 of a tachometer measuring engine speed. Another tachometer measures rate of travel which is indicated on scale 34 and recorded in the outer area of chart 22. A stack of charts, (Fig. 4 not shown) may be provided for a week's recording. In another embodiment engine speed is recorded over the full range one side of a chart and rate of travel on the reverse side. The idle time of engine can be recorded as shown in Fig. 5 by using an electric circuit including a snap-action switch 42 and heating wire 43. The switch 42 is closed by a frame part 17<SP>11</SP> through a switch part 45 and snap-action spring 48 while a spring 49 holds a frame part 17<SP>1</SP> against a stop 57, which the stylus 19 in zero position. When the ignition 41 is switched on the wire 43 heats up and expands, allowing a spring 52 to rock a lever 50 and lift the frame 17<SP>11</SP>, this raises the stylus 19 slightly and opens contacts 46, 47. The wire 43 cools, stylus 19 returns to zero and the contacts 46, 47 remake. A bar diagram 58 is thus produced while the engine is idling, but as soon as the engine speed rises the wheel 16 drives the rack 17 and the stylus records a graph 59 of its rotation speed. The speed measuring systems may be of eddycurrent or centrifugal pendulum type.

Abstract: 939,632. Steering vehicles. ZAHNRADFABRIK FRIEDRICHSCHAFEN A.G. Dec. 11, 1961 [Dec. 14, 1960], No. 44280/61. Class 79(5). In a power-assisted steering system, a steering worm 1 co-operates with a steering nut 2 which is formed as a valve member, pressure fluid being admitted through a port 5 to the steering housing 3 which is formed as, a cylinder for the working piston 4 to one side or the other of which pressure fluid is directed to assist the steering action and which co-operates with the steering nut through reaction pistons 34 acted upon by pressure fluid and by springs 33. In the straight ahead position the pressure fluid passes through the passages 6, 12 and 13 into the worm chamber 14 and thence to the reservoir or return line to the pump. At a steering action, the nut 2 moves relatively to the piston 4 whereby the valve mechanism is actuated to direct fluid to one side or the other of the piston through the passages 8 or 10 and pressure fluid passes to the chambers 32 containing the reaction pistons 34 by way of pressure reduction valves 22a, 22b, each of which comprising the spool 22a, 22b urged to the right by spring 25, the bores 28, 29 and 24 and the pressure surfaces 36 and 37, the surface 37 being of greater area than the surface 36 so that the spool is moved to the left by fluid pressure until the admission of fluid through the passage 28 is checked by the sleeve 23 and an equilibrium position is reached at which the fluid pressure in the reaction chambers is lower than that being supplied to the power piston. If the latter pressure increases, the pressure on surface 36 increases and the spool 22a, 22b moves to the right so that fluid at a higher pressureis admitted and the process is repeated at a higher pressure value. When the fluid pressure being supplied to the power piston drops, e.g. by return to the straight ahead position, the valve member 22a, 22b moves to the left to the point where the. pressure fluid from the reaction chambers can escape through the passage 28 and space 40 and thence to the space 14.

Filed: 1971-09-24
Abstract: 1354587 Welding by fusion KOBE STEEL Ltd 24 Sept 1971 [26 Sept 1970] 44628/71 Heading B3R [Also in Division H2] A method of consumable electrode vertical arc welding comprises repeatedly alternating (a) welding for a period t 1  using a current A 3  and (b) welding for a period t 2  (> t 1 ) using a current A 1  (< A 3 ), consumable electrode wire being fed at a greater speed during t 1  than during t 2 . The higher current A 3  allows a large amount of molten metal to be supplied to the molten pool, and the lower current A 1  allows the molten metal to cool and thereby prevents molten metal from dropping down. Change of wire feed speed to meet current change provides for a constant arc length. A 3  = 150 to 450 amps, A 1  = 30 to 150 amps, A 3 -A 1  = 120 to 300 amps, t 1  = 0À2 to 3 seconds, and t 2  = 0À2 to 5 seconds. Preferably the wire feed rate is directly proportional to current. Wire feed rate adjustment is carried out mechanically or electrically before current change. The method may include the use of a self-shielded flux-cored electrode wire; vertically upward, constant-speed torch movement accompanied or not by weaving thereof; and A.C., D.C. or pulse current. In Fig. 2, a torch 3 and workpiece 5 are connected in a circuit comprising the secondary winding 2 of an A.C. transformer T, and two inversely connected, parallel, controlled rectifiers 6. The latter are controlled by a gate circuit 7 which is connected in the transformer primary winding 1, determines A 1 , A 3 , and is connected to a timer 8 determining t 1 , t 2 .

Abstract: 1,154,590. Hydrostatic transmission. CHRYSLER CORP. 12 Oct., 1966 [21 Oct., 1965; 13 Dec., 1965], No. 45582/66. Headings F2C and F2D. In a hydrostatic transmission for a motor vehicle wherein a pump cylinder body 20 is fast with an input shaft 30 and has pistons 32 engaging a fixed inclination swash-plate 24 fast with a motor cylinder body 22 which is fast with an output shaft 40 and has pistons 56 engaging a variable swash-plate 26, a valve 262 is provided to block the high pressure line 174, 179 between the pump and motor when the motor swash-plate is vertical and thus reduce hammering noises, vibrations and leakage in direct drive. The motor swash-plate 26 pivots about cylindrical surfaces 96, 98 and its inclination is automatically varied by a servomotor 118 supplied with pressure liquid from a control (not shown) responsive to transmission pressure, accelerator pedal position and engine speed. When the swash-plate 26 is vertical it closes a valve 266 whereupon pressure builds up in a duct 364 and chamber 318 (Fig. 1Q) and moves a piston 302 right against the bias of springs 312, 314. The piston 302 acts through a rod 330 to move right a spool 274 of the valve 262 whereupon a surrounding sleeve is urged by a spring to follow the movement of the spool 274 to close a part 158 between the pump and motor high pressure lines 174, 179. A valve plate 146 which interconnects the pump and motor high pressure lines and connects the motor low pressure line to a chamber 178, is rotated through 180 degrees for reverse ratio by selectively supplying pressure liquid to servomotors 251, 252 the pistons 257, 258 of which act through a rack 264 and pinion 248 to rotate the valve plate. High pressure liquid passes through ducts 372, 380, 382 to a modulator valve 462 (Fig. 1P) in a stationary end plate 220 and modulated pressure passes through ducts 483, 442, 436 to the control for the servo 118. The modulated pressure moves a shuttle valve 478 (Fig. 1P) left whereupon make-up liquid is supplied to the chamber 178 through ducts 472, 476, 394, 396, 398. During overrun the higher pressure which is in the low pressure ducts acts through a duct 480 to move the shuttle valve 478 right whereupon the higher pressure is supplied to the control whilst make up fluid is supplied through ducts 472, 484 to the normally high pressure ducts. A by-pass valve (402), (Figs. 1 and 1T, not shown) in the duct 382 is normally held closed by pressure liquid supplied to a piston (404) but in neutral the pressure supply is cut whereupon the valve opens to short circuit the high and low pressure lines.
