Title: Improved fluid pressure power steering mechanism for a motor vehicle
IPC: F15B9/08
Filed: 1958-09-18
Abstract: 834,761. Vehicle power steering. GENERAL MOTORS CORPORATION. Sept. 18, 1958 [Oct. 2, 1957], No. 29901/58. Class 79(5) In a fluid pressure power steering system operating through a screw shaft 48, Fig. 1, and nut 42 the control valve is actuated by the relative movement between the screw shaft 48 and a manually rotated steering member 16 interconnected by a torsion bar spring 78. The steering member 16 is rotated by a steering wheel (not shown) mounted on a steering shaft 12 connected to the member 16 through a flexible coupling 10. The torsion bar spring 78 passes through the valve body 24 and is connected to the screw shaft 48 which has a recirculating ball connection 50 with the nut 42 and operates the steering gear through a rack and pinion 44. The nut 42 is formed ,as a power piston sliding within the cylinder 40. The servo valve mounted within the body 24 is rotary and comprisesan inner sleeve 70, Fig. 2, mounted on the steering member 16 and positively rotated therewith through a pin connection 72. An outer sleeve 30 is coupled for positive rotation with the screw shaft 48 through a pin and slot connection 60, 62 and is positively connected to the torsion shaft 78 through a flanged end plate 90, 94 having pin connections 88, 102 with the shaft 78 and sleeve 30. Lost-motion connection between the steering member 16 and screw shaft 48 is provided by tangs 100 integral with the shaft 48 and extending with slight clearance into slots of a flanged end 17 of the member 16. The outer sleeve 30 has a central peripheral groove 110 communicating with the power supply line 120 and has a pair of peripheral grooves 112, 114 communicating through passages 130, 132 with opposite ends of the power cylinder 40. The supply groove 110 is connected through radial passages 134, Fig. 7, with axial grooves 140 on the inner face of the sleeve 30 and the power cylinder grooves 112, 114 are connected to slanting passages 136, 138 circumferentially spaced around the sleeve 30 and opening in the region of longitudial slots 146, 148 on the outer face of the sleeve 70. Intermediate lands 162 of the sleeve e 70 have passages 150 communicating with the exhaust line 158 through an annular chamber 54 and Belleville spring 32. Lands 160, Fig. 6, between the grooves 146, 148 have chamfered edges 161 to provide for the circulation of pressure fluid when the servo valve is in the neutral position. In operation, steering effort causes initial twisting of the torsion bar spring 78 with a resultant relative movement between the sleeves 30, 70 to create a pressure differential on opposite ends of the piston 42 to balance the steering resistance. The chamfering 161 provides for gradual increase of fluid pressure so that the feel on the steering wheel is proportional to the steering resistance until the full deflection of the torsion bar spring 78 is taken up.

Title: An improved spring balance or the like
IPC: G01G3/04
Filed: 1924-12-15
Abstract: 232,888. Linsdell, J. M. Dec. 15, 1924. Spring balances.- A portable or pocket spring balance for weighing suspended articles is provided with a number of springs which may be selectively employed for the weighing operation. The load hook 12, Fig. 2, is connected by a square bar 3 and a shank 4 to a light spring 9. By turning the bar 3 and shank 4 through a right angle a cross pin 10 on the shank bridges a rectangular aperture 5 in a plate 6 attached to the stronger springs 7, and in this position all the springs are operative to resist the pull of the load. In the position shown, the cross pin 10 passes through the aperture 5, and the light spring 9 only is operative. A pointer on the base of the casing indicates the weight in co-operation with graduations on the bar 3. A notch is provided in the periphery of the base of the casing to allow the point of the load hook to be slipped over the base for convenience in carrying the pocket. In a modification, Fig. 5, the springs act in compression, the weaker spring a being arranged within a stronger spring c. The load on the hook 12 draws down an outer case e and also a rod b surmounted by a triangular head j. In one position, for weighing small loads, the triangular head passes through a triangular aperture i in a plate f arranged above the stronger spring, and only the weaker spring is then operative. For weighing heavier loads the outer casing is turned so that the triangular head j engages the plate f thus bringing both springs into action. The outer case e is pierced by an elongated U-shaped slot the vertical limbs of which are graduated to give readings of the light and heavy weights respectively.

Title: Process for the separation of the solid substances in products and residues of the destructive hydrogenation of distillable carbonaceous materials
IPC: C10G21/14
Filed: 1934-10-22
Abstract: Solids are separated from the residues obtained in the destructive hydrogenation of carbonaceous materials by adding thereto aliphatic hydrocarbons rich in hydrogen and boiling below 50 DEG  C., in small proportions up to 20 per cent so that substantially all the solids, but only part of the asphalts, contained in the residues are precipitated.  Preferably liquefied hydrocarbons are used, e.g. liquefied propane or butane.  The asphalts remaining in the oil may be converted into valuable products by further destructive hydrogenation or they may be precipitated in known manner by the addition of liquefied hydrocarbons.  100 parts of an oil obtained by centrifuging destructive hydrogenation residues and containing 11,3 per cent asphalt and 10 per cent solids are mixed at 90 DEG  C. with 10 parts of commercial butane.  67 parts of oil free from solids are obtained while the residue contains 20 per cent of solids and 20 per cent of the asphalt contained in the original material.  The treatment may be repeated to obtain further precipitation of solids. Specification 409,278 is referred to.

Title: Web handling system

Filed: 1965-07-16
Abstract: 1,110,545. Fluid-pressure-electric servomotor systems. CANADIAN GENERAL ELECTRIC CO. Ltd. July 16, 1965 [July 25, 1964], No. 30374/65. Headings G3P and G3R. [Also in Divisions B6 and F2] Variations in the length of a web loop 6 in a suction column 5 are detected by a light-sensitive arrangement, the output of which is fed to a lead circuit and amplifier which controls the operation of a hydraulic valve 94 Fig. 10 governing the hydraulic pressure applied to a brake 18 on the web-roll 9. Valve: Liquid is pumped from the reservoir via a flow valve 82 to the cylinder of the brake 18, and the pressure is varied by allowing the liquid to bleed off via orifice 101 under the control of valve member 103. High-pressure liquid flows from a tube 91 and through an orifice 93 to impinge on the upper surface of the valve member 103. By deflecting the tube 91 with an electromagnet 109 controlled by the lead circuit and amplifier, the amount of liquid impinging on the upper surface of the valve member 103 can be varied. The equilibrium position of the valve member 103 is therefore varied, thereby varying the bleed off of liquid from the orifice 101. The pump pressure is controlled by an adjustable pressure relief valve 84, having a safety valve 85 placed in parallel therewith. . Suction column: A series of lamps 56, Fig. 6, are positioned alongside an inner glass wall 52, <SP>"</SP> so that light rays 58 passing through that portion of the suction column not occupied by the loop strike a reflecting surface in the column. Some of the reflected rays 59 impinge on a lightsensitive device 60 such as one or more semiconductor cells, which converts the light energy to electrical energy. The electrical signal obtained from the device 60 represents the position of the loop 6 relative to the column, and this signal is fed into the lead circuit and amplifier to control the brake. To compensate for the change of inertia of the web-roll 9 as the diameter thereof decreases, a mask (117, Fig. 12) may be placed in the light gathering box 55 of the column, so that the pattern of light transmitted through the box is altered, so that the signal is modified according to loop length. To compensate for friction between the web loop and the side of the column, the suction column may have a pair of converging side walls (121 and 122) Fig. 13 which converge according to the expression ° = 2 sine<SP>-1</SP> Á, where ° is the angle between the side walls and 4 is the apparent coefficient of friction between the web and the side wall in frictional engagement with the web during withdrawal from the column. To accommodate webs of different width, each end wall of the suction column may be mounted for transverse movement on a "scissors jack" (140) Fig. 15.
