Title: Vehicle suspension systems
IPC: B60G11/36
Filed: 1936-07-31
Abstract: 456,328. Vehicle spring-suspensions. GENERAL MOTORS CORPORATION, Grand Boulevard, Detroit, Michigan, U.S.A. July 31, 1936, No. 21225. Convention date, Aug. 5, 1935. [Class 108 (ii)] In a vehicle-suspension system a main spring and an auxiliary spring are arranged as a toggle which is straight in the normal load position so that the auxiliary spring reduces the effective rate of the main spring at and adjacent its normal load position and as a deflection in either direction proceeds the force of the auxiliary spring decreases permitting the rate of the main spring to increase. As shown the axle 1 is carried by the mainspring 3 which is pivoted to the frame at 4 and to a shackle 5 at 12 while the auxiliary spring 7 is pivoted also to the shackle 5 at 12 and to the bracket 10 secured to the frame. The auxiliary spring 7 is at its maximum compression in the position shown and on deflection of the main spring 3 the auxiliary spring force assisting deflection decreases. In another arrangement the spiral spring 7 is replaced by a Belleville washer spring the washers of which may be arranged in series and in parallel to alter the characteristics of the spring. Fig. 3 shows an auxiliary spring combined with a hydraulic shock absorber. The auxiliary spring assembly is pivoted at 47 which is offset from the main spring pivot 46 on the shackle 6 so that the effect of expansion of the spring 8 during deflection of spring 3 is modified. The spring 8 is arranged between thrust seatings 20, 21 which have a sliding fit in the bore of the member 15. The spring surrounds a member 16 and the whole is enclosed by a housing 17 with bellows 24 and filled with oil. The stem 16 is provided with a bore 26 communicating by ports 27 with annular chamber 29 and with the chamber 30 through ports 28 and valves. Valve 31 is pressed on its seating 33 by a weak spring 32 and a valve 35 with spring 36 is arranged in the valve 31, these valves permitting under restraint flow of oil from chamber 29 to chamber 30 on relative movement of the members 15, 16. After a predetermined deflection head 22 contacts with thrust seating 20 and the seating 21 contacts with stopped ring 23 so that further deflection causes the spring 8 to resist such deflection and adds resistance to the main spring.

Abstract: 914,316. Transistors. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 23, 1959 [June 26, 1958], No. 21493/59. Class 37. The Specification relates to the method of making transistors wherein two superimposed zones 4, 5, Fig. 2D, of different conductivity type, e.g. P (Al) and N (Sb) respectively are formed by diffusion on a body 1 of conductivity type N (Si) and comprises the steps of, prior to this diffusion treatment, diffusing in an impurity, e.g. boron, producing a zone 2, 3, Fig. 1A, of a conductivity type P opposite to that of the body 1 and removing this zone over part of the surface, Fig. 1B, this impurity having a greater solubility and at least the same diffusion coefficient as that of the impurity producing the outer zone 5. A portion of this remaining zone is removed, either after the simultaneous diffusion of zones 4, 5 or prior to the diffusion of a collector contact 8 to the body 1. In the former case this contact 8 is directly in contact with the body 1 and in the latter case contact 8 contacts the body through a layer 10 of the impurity antimony diffused in when forming the layer 5. Emitter and base contacts 7, 9 are thus provided. The body may be of germanium, the initial impurity arsenic, and the two differing conductivity type zones of antimony and indium.

Title: Improvements in or relating to controllable pitch propellers
IPC: B64C11/42
Filed: 1937-08-04
Abstract: 505,077. Fluid - pressure servomotor - control systems. UNITED AIRCRAFT CORPORATION. Aug. 4, 1937, No. 21532. Convention date, Aug. 4, 1936. [Class 135] [Also in Group XXXIII] In hydraulic-actuated pitchadjusting means for the blades of screw propellers, adjustment in the normal range is obtained with low pressure, stops preventing movement outside the range, whilst with higher pressure the blades are moved beyond to greater pitch positions for feathering. The blades 14 carry at their roots bevel wheels 162 meshing with a bevel wheel on a cam sleeve 30 having grooves each of two pitches 82, 88. Concentric with cam sleeve 30 is another 28 also having grooves of two pitches 78, 86. The piston 20 which is formed of concentric sleeves 21, 23 joined by a web 25 carries drive members 22 having ball-bearings 24, 26 engaging the cam surfaces' of the two sleeves whereby longitudinal motion of the piston produces rotation of the inner cam sleeve 30 and pitch adjustment. The piston 25 moves in a cylinder 18 and has packing 44 to maintain fluid tightness. Oil of low pressure from a pump 142 controlled by a centrifugal governor passes by pipe 150 to openings 32 and 36 in plugs 34 and 38 and thence through passages 40 to the side of the piston facing the propeller to alter pitch oppositely to the control imposed by the centrifugal force on the blades. The oil is free to pass to the cams and pitch actuating gear. The oil pressure is sufficient to move the piston so that the pins 22 follow the first pitches 78 and 82, but insufficient to utilize the steeper pitch grooves which act virtually as stops for. the normal range of pitch change To pass beyond this range to full feathering position, a pump 156 working at higher pressure is used, the oil moving through a chamber 152 to close a valve 160 'and cut out the pipe line 150 from the supply pipe to the propeller. With this higher pressure the piston is moved and the pins 22 pass along the higher pitch grooves 86, 88 in the cam sleeves. When a still higher pressure is used, oil passes through the valve 92 by passages 100 and holes 102 to the forward face as well as the after face of piston 25, which by reason of the annulus 90 has a greater area on the after face whereby the piston is moved back and the blades are returned from feathering position to the normal range. The tube 64 acts as a return conduit and is connected to the sump 140. A valve 108 is held open bya spring to allow oil to drain from the cylinder through holes 110 and tubes 52 and 64 when the pressure is released, but when pressure oil is passed to the cylinder it acts on the valve to close it. In addition when the piston has moved to the limit to the right, the nut 128 thereon contacts with a flange 130 on the valve 108 to open it. The cam sleeves have projections which may be engaged by discs which determine the high and low pitch positions. Specifications 355,329, 399,205, 416,255, and 470,284 are referred to.
