Abstract: 507,623. Perambulators ; ventilating. CHEMA, Ltd., and SIGMUND, J. Oct. 25, 1938, No. 30879. [Class 108 (i)] [Also in Group X] A perambulator, for use during gas attacks, comprises an air-tight chamber 1 or contains an air-tight protective bag, and is fitted with blowing means for supplying filtered air to the chamber or bag, said means being driven by a member, such as a handle 12, when the perambulator is stationary and by mechanism, such as a crank on the axle 11 of the road wheels, when the perambulator is in motion. In the construction shown, the crank actuates a double-acting blower 4 which draws in air through valves 6, 7, and forces it through valves 8, 9, to a conduit 10 leading to a filter 2. The handle 12 is connected to a bellows 5 which also forces the air through the filter 2 and thence into the chamber 1. The blower 4 may be arranged in front of or beneath the perambulator and the entire filtration apparatus, with the exception of the handle 12, may be so arranged that it is completely covered in.

Title: Improvements in or relating to Hydraulic Machines for Handling Variable Loads and Drawworks Comprising such Hydraulic Machines
Inventor: BROWN CICERO COLUMBUS
IPC: B66D1/08
Filed: 1966-11-14
Abstract: 1,160,678. Hydrostatic transmission; band brakes. C. C. BROWN. 14 Nov., 1966 [24 Jan., 1966], No. 51012/66. Heading F2C, F2D and F2E. In a hydrostatic transmission for a winch wherein a manually controlled variable displacement swash-plate pump 18 supplies pressure liquid to one or two variable displacement swash-plate motors 40, 41, a pressure sensitive device 48 causes an increase in the motor displacement when the supply pressure exceeds a predetermined value and thereafter, for a given input power, maintains a constant output power as the load varies. The pump 18 and motors 40, 41 are connected by lines 36, 38 and the high pressure line is connected by a shuttle valve 58 to the pressure sensitive device 48. When the load and thus the high pressure exceed a predetermined value a piston 54 of the pressure sensitive device 48 is moved down against the bias of a spring 52. The downward movement of the piston 54 moves down the spools of follow-up valves 62<SP>1</SP> which supply pressure liquid from a pump 102 to displacement adjusting servos (74<SP>1</SP>), (Fig. 2, not shown) of the motors 40, 41. The pump displacement is varied by supplying pressure air through a manually operated valve (65) to a chamber 64 having a spring centred piston (66) fast with the spool of a follow-up valve 62 which supplies pressure liquid from the pump 102 to a displacement adjusting servo (74). A one-way valve 134 in the line 38 which is the high pressure line when the winch is hauling-in prevents reverse flow in the event of the system failing and therefor brakes the motors. When reeling out the pressure in the line 36 opens a valve 136 in parallel with the valve 134 and permits flow from the motors 40, 41 to the pump 18 through the line 38. Relief valves 114, 142 are provided. An air pressure operated valve 138 isolates the pump and motors when the winch is not in use. A valve 140 operated simultaneously with the valve 138 supplies make-up fluid from a pump 104 to the motor circuit when isolated from the pump. Liquid returning to a reservoir 130 passes through a cooler 128 and filter 132. A motor 124 driven by the pump 102 operates a fan 126 which blows air through the cooler 128. Band brake.-A band brake (166), Fig. 7 (not shown), for the winch drum (42) is engaged by springs (160) acting through a rod (162) and lever (164) on the end of the brake band. When the pump control valve (65) is moved from a neutral position to a forward or reverse drive position compressed air is supplied to a cylinder (168) which acts through a lever (170) on the rod (162) to disengage the brake.

Title: Cathode ray tube display system and method

Abstract: 1,033,239. Cathode-ray tube circuits. FORD MOTOR CO. Ltd. Dec. 19, 1964, No. 51735/64. Heading H4T. In a single-beam cathode-ray tube display arrangement, the beam of which is sequentially directed towards different areas of the screen and at each area caused to draw a particular part of the complete display with a trueing speed which may vary from area to area, the overall brightness of the display is maintained constant by making the brightness with which the different areas are traced individually adjustable. Considering four areas, the trace for each area is rendered visible by the " ON " condition of one of four bi-stable multivibrators 2 ... 5, the other three being " OFF," all of which feed respective voltage clamps 6 ... 9 the output of each of which during the " OFF " condition is equal to Vc volts. These outputs are fed to one end of respective potentiometers 10 ... 13, the other ends of which are connected to a constant source of Vc volts so that a p.d. exists only across the potentiometer appropriate to the multivibrator in the " ON condition, the " ON " voltage being greater than Vc. An output from such potentiometer at a level determined by the setting of the appropriate slider 14... 17 is then fed via summing amplifier 18 to control the beam brightness in tube 1, the voltage at the other three sliders at this instant, each equal to Vc volts, being cancelled by a voltage equal to - 3Vc supplied to amplifier 18 from a constant source. The invention is stated to be applicable in the designing of motor vehicles whose different parts of a vehicle traced on the tube screen are liable to oscillate at different frequencies in response to varying road conditions as represented by signals derived from a computer.

Title: Method for rolling hot metal workpieces

Filed: 1971-11-15
Abstract: 1373375 Rolling and coiling metal STEEL CO OF CANADA Ltd 15 Nov 1972 [15 Nov 1971] 52995/71 Headings B3M and B3E A method of rolling a hot metal workpiece'in a mill plant including a first mill comprising a reversing mill stand 28, e.g. a roughing mill, a coiler 29, and a second mill 19-24, e.g. a finishing mill, comprises rolling the workpiece in the first mill, so that after its third last pass, from the side remote from the coiler to the side nearer the ooiler, it is of a length less than the distance from the stand to the coiler, and after its last pass, in the same direction, it is of a length greater than that distance, coiling it in the coiler, and uncoiling it and passing it to the second mill. A shear 18 is provided, and the final product is wound on one of coilers 25, 26, 27. The coiler 29 is shown in Fig. 8, together with entry and exit tables 73, 75, and hot metal detectors 78, 79. On its final pass from the stand 28, the workpiece 30e, which may be strip or rod, passes through pinch rolls 54, 55 and guide 56 to a three roll bender 57, 58, 59, so that the leading edge of the strip forms a coil supported on rolls 69, 70. As the coil grows, it falls on to rolls 68, 69. The table rolls, rolls 54, 55, and rolls 57, 58, 59 are all driven at the same peripheral speed, and rolls 68, 69, 70 slightly faster. When detector 78 senses the leading end of a workpiece, the table roll drive is stopped unless detector 79 indicates that the coiler is clear. When the leading edge reaches the bending rolls, roll 54 is raised slightly so as to function as a guide rather than a pinch roll. When detector 78 senses the trailing edge of the workpiece, rolls 58 and 59 are raised so that the coil is left with a straight end to facilitate uncoiling, and when the trailing edge leaves rolls 54 and 55, rolls 68-70 are decelerated so that the trailing end passes over the top of the coil and falls on to table 75. Uncoiling starts automatically, but if it is necessary to delay uncoiling, the coil is slowly rotated. When detector 79 senses the leading end of the workpiece, rolls 58 and 59 are reset, and the shear may be actuated. A retainer is inserted into the coil to retain it as the last few turns are unwound. When detector 79 senses the end of the workpiece, the retainer is withdrawn and the shear again actuated. A turn peeling device may be moved into operative position if uncoiling fails. The workpiece may be of steel or aluminium.
