Abstract: 896,642. Dashpots; maintaining constant vehicle height REGIE NATIONALE DES USINES RENAULT. Nov. 18, 1958 [Dec. 6, 1957], No. 37068/58. Classes 108(2) and 108(3). Valves 22, 23 (Fig. 3) for controlling the admission and exhaust of air from a telescopic pneumatic vehicle road-wheel spring are adapted to be operated by movement of a plate 18 connected by a spring to one of the telescopic spring members 13, 14. The plate, on movement up or down from the position shown, corresponding to normal vehicle height, engages the valve 22 or the valve 23 respectively. For rapid movements of the vehicle axle, connected to the member 14, the plate 18 is held from movement by a dashpot 1 which has piston rods 3, 3<SP>1</SP> (Fig. 2) rigid with the member 13. Movement of the piston 2 relative to the cylinder 1 forces liquid through a flow restriction 9<SP>1</SP> into a chamber bounded by a flexible diaphragm 5. On return movement, liquid can flow back freely to the cylinder 1 via a non- return valve 11.

Abstract: 1314436 Moulding powder WOLVERINE PENTRONIX Inc 3 Aug 1970 [10 Nov 1969] 37315/70 Heading B5A Apparatus for the production of fluid saturated compacted articles comprises one or more die cavities 28 in a die-plate 22 supplied with powder 29, an anvil 31 which closes the powderfilled cavities, punches 54 which compress the powder in the cavities, and means for injecting a fluid into the powder in the cavities prior to compacting the material comprising a passage 74 which opens into each cavity between the anvil and a punch 54, which punch closes the passage during compaction to meter the amount of fluid injected. The fluid is supplied from a pressure source 76 and passages 70, 74 in a stationary core rod 62, and the punches are secured to a holder 42 raised by a member 48 and slidable in a housing 30 bolted to the dieplate. In the embodiment of Fig. 3 the core rods are omitted and the fluid is supplied to the punch housing 30a from a pressurized source 87 via a valve 89 actuated by a rotary cam 91, and a supply line 88. The fluid is held above the holder and injected into the powder filled cavities via passages 90, 92. A predetermined amount of fluid is supplied to the housing and die cavities on timed actuation of the valve 89 whereby the fluid is supplied from the source by a pump 99; during the greater part of the press operation the line 88 is connected via the valve 89 with a line 85, and provides for refilling of the housing when the punch holder moves down to the powder-fill position. In a further embodiment the fluid is fed into the die cavities via passages formed between the upper ends of the punches and the inner walls of the dies, Figs. 5 and 6 (not shown). An embodiment is described in which core-rods with axial bores and transverse injection passages extend axially into the die cavities similarly to that shown in Fig. 1, but which are slidably disposed in the punch housing, and fluid to be injected is supplied to the housing below the punch holder and passes through further transverse bores in the core rods to their axial bores. In Fig. 9 the fluid is injected through orifices 112 of an axially reciprocable core rod which recedes as the punch is raised and so that the rod and punch form a single unit during the final compression stroke.

Abstract: 1,259,883. Semi-conductor devices. SIGNETICS CORP. 25 July, 1969 [26 July, 1968], No. 37426/69. Heading H1K. A semi-conductor assembly 49 comprises a plurality of circuit elements 29 formed in a body of semi-conductor material and has beam leads 43 connected to the circuit elements, there being a layer 14 of insulating material encapsulating the body. The circuit elements are isolated from one another, in the various embodiments described, by reverse biased PN junctions, air, or solid dielectric material, and from an integrated circuit. The semi-conductor material used is silicon. The method of forming the assembly in the embodiment wherein isolation is provided by reverse biased junctions comprises etching grooves in a wafer of monocrystalline silicon, covering the grooved surface with a layer of silicon dioxide, and growing a support body of polycrystalline silicon over the surface. The monocrystalline silicon is then removed by grinding to expose the polycrystalline silicon at the bottom of the grooves so that islands of monocrystalline silicon are formed in which the circuit elements are provided in conventional manner. Following this a layer 28 of silicon dioxide is grown over the surface and a beam lead construction is formed by etching contact windows 42 in the layer 28 and sputtering platinum over the whole surface to form a platinum silicide layer which is etched away except for the parts 44 in the windows, a layer 46 of titanium is then deposited, followed by a layer 47 of platinum and a final top layer of gold which may have a greater thickness at its outer extremities which form the beam leads than it has elsewhere. Finally the support body of polycrystalline silicon is removed. Silicon nitride and aluminium oxide may also be used as the insulating layer material. Methods of forming assemblies with air and dielectric material isolation are also described.

Title: Aquasols containing hafnia or zirconia
IPC: C01G25/02
Filed: 1965-09-03
Abstract: Aquasols of hafnia or zirconia or both are prepared by replacing anions from an aqueous solution of a basic salt of hafnium or zirconium or both by hydroxyl ions for a time that is sufficient for the specific conductance of the dispersion to become constant.  The anions may be replaced by electrodialysis in which case the aqueous solution is maintained at 50-70 DEG  C. or by contacting the aqueous solution with an anion exchange resin in the hydroxyl form in which case the temperature is 50-80 DEG  C.  The aquasols are colourless and translucent, contain less than 30% solids in the dispersed phase, and the particle size is within the range 3 to 10 millimicrons.  The dispersed phase, which may be separated from the aqueous phase, is amorphous.
