Title: Hydraulic surface treating process and apparatus
IPC: B28C5/06
Filed: 1960-09-07
Abstract: 965,551. Blasting. AJEM LABORATORIES Inc. Sept. 7, 1960 [Feb. 19, 1960], No. 30841/60. Heading B3D. [Also in Division B2] A process for surface reforming an article with a liquid jet which has surface-reforming particles entrained therein, comprises the steps of maintaining a supply of said particles in a zone, forming a high velocity liquid jet, entraining the particles from said zone in the jet, said jet being formed with high velocity for imparting surface reforming energy to the entrained particles, and directing the resulting combined blast of liquid and entrained particles through a guide tube and against the surface of the article to be treated with surface reforming energy, said guide tube providing a substantially unconstricted path for said blast. A combined hopper and hydraulic purifier 1, Fig. 1, is in the form of a truncated cone. In the bottom is adjustably mounted a jet tube 2 having an orifice 2<SP>1</SP> and communicating through a pipe 4 with a source of clear water under high pressure. Above the jet tube 2 is a vertically adjustable guide tube 5, of circular cross-section, which does not extend quite to the bottom of the hopper but does extend above the liquid level in the hopper. The upper part 6 of the guide tube is of larger diameter than the lower part. The high velocity stream emerging from the port 6 strikes a workpiece directly above it. Spent blast liquid is kept from scattering by a hood 7 and drains into the hopper causing an overflow at the periphery into a gutter 8. The overflow carries with it particles having lower settling rates, while the re-usable grains settle and are re-used. Make-up grains, and chemical agents if used, are introduced into the hopper as necessary. The effluent may be run off to a settling basin in which any remaining abrasive is allowed to settle out before it is pumped. In a modification, Fig. 2, the jet tube 2a, guide tube 5a and hopper 1a are of rectangular cross-section. The jet tube 2a may comprise a number of cylindrical tubes arranged side by side. In a further modification, Fig. 4, a low velocity pump and mixer feed a suspension of surface-reforming grains through a pipe 12 to the hopper 1b. Preferred dimensions, velocities and pressures are stated.

Abstract: 1467363 Change speed control DAIMLER BENZ AG 15 July 1974 [20 July 1973] 31285/74 Heading F2D A valve for varying hydraulic pressure applied to friction clutches and brakes in an automatic transmission on a motor vehicle in accordance with the valuable excitation of a solenoid 1, controlled by e.g. engine torque as manifested by engine intake depression or fuel control rod stroke, comprises an iron casing 4, 5, 6, enclosing the solenoid winding 1 and terminating in two concentric cylindrical pole pieces 7, 8 forming an annular gap into which is variably drawn an armature 21, preferably formed as a ring of segments, attached to a support 12 which is of a material, e.g. aluminium, the same as, or having the same thermal expansion coefficient as, that of a housing 9 accommodating the solenoid and its iron casing. The armature segments 21 are attached to the support 12 by rivets 20 integral with the latter. The armature support 12 is integral with a stem 11 supported for axial movement at both ends by resilient diaphragms 14 which may have expansion slots and may seal the magnetic section from the valve section, and may carry paper filter discs. The valve section comprises a seat 19 screwed in a flanged support 22 secured in the housing, the seat co-operating with a closure member 18 attached to the armature support 12, to control a valve gap for variably exhausting liquid supplied through the bore of the support 22 to a concentric surrounding exhaust outlet shown by the arrows. The armature and closure member 18 are loaded downwardly to close the valve gap by an adjustable spring 17, the gap being variably opened in accordance with the energization of the solenoid. To protect the lower diaphragm 14 from the dynamic force of liquid passing through the valve gap, the closure member, which is prismatic in section, passes with slight clearance through a fixed partition 25. The solenoid space between the two diaphragms 14 is filled with a liquid of low viscosity and thermal expansion coefficient, and the two spaces lying above and below that space communicate through a bore 13 in the armature support stem 11. In Fig. 2, not shown, the solenoid valve is screwed from the outside into a threaded bore in the transmission casing, and regulates pressure in a loading chamber of a regulator valve 34 inside the casing, communication with the chamber being through a hollow extension plug on the regulator valve body slidably and sealing- ly entering the bore of the solenoid valve in place of the magnetized insert 26 which latter is now installed in the inlet to the regulator valve. An additional loading spring (38) of the latter sets a minimum pressure sufficient for engine braking.

Patent GB-877725-A (GB)
Title: Preparation of cyanuric acid
Filed: 1957-10-07
Abstract: Free-flowing granular cyanuric acid is prepared by heating urea in a rotary kiln to a maximum temperature in the range 240 and 360 DEG C. The peripheral speed of the kiln may be 50-1000 inches per min.  The kiln may be cylindrical stainless steel, with a horizontal, or slightly inclined, axis, of length equal to, to 4 1/2 times, the diameter, heated by external gas flames or by a flame, or current of preheated gases, passed into the kiln. The process may be batch, or continuous, and in the latter case a bed of pellets is established in the kiln and maintained at a constant level.  The yield of cyanuric acid is increased by passing inert gas, e.g. air, N2, or flue gas through the kiln, or by partial evacuation of the kiln.  The crude product from the kiln, after grinding, if desired, is digested in hot dilute aqueous strong acid, e.g. 1-25%, HCl, HBr, H2SO4, HNO3 H3 PO4, or alkyl, o aryl, sulphonic or phosphonic acid, preferably boiling 3-15% HCl, to dissolve basic impurities and hydrolyse amides and ureides of cyanuric acid to cyanuric acid.  Digestion may be at atmospheric, or super-atmospheric, e.g. up to 100 lbs/sq. in., pressure.  The effluent gases from the kiln may be scrubbed with water to recover ammonium cyanate, which is converted to urea by heating the scrubbing water.  The urea may be returned to the kiln.

Title: Improvements in appliances for measuring the gaps of piston rings in cylinders
IPC: G01B5/08
Filed: 1935-11-18
Abstract: 455,677. Linear - dimension gauges. SPARK, M. A. M., 31, Mealmarket Street, Aberdeen. Nov. 18, 1935, No. 31887. [Classes 106 (ii) and 106 (iv)] A device for measuring the gap of angle cut piston rings in the operative position comprises means for supporting the ring in a plane normal to the axis of the bore in which it is to be used, a member adapted to be deflected by the flexing of at least one of the piston ring ends and a gauge pointer for indicating this deflection when the ends touch. Straight edge members 1, 2 are grouped around and connected to a common hub formed by a headed spindle 3 on which is an upper boss 4 prevented from axial movement on the spindle. The lower end of the spindle is threaded into a hub 5. The boss and hub are connected to the members 1, 2 by lazy-tongs mechanism 6, 7 so that the device can be inserted into a bore and expanded against the surface. The upper ends of the members 1 determine a plane so that when the piston ring 11 to be tested is pressed down on to these ends the ring lies in its proper position normal to the axis of the bore. The element 2 is shorter than the members 1 and receives the socket 12 of a frame 13 supporting a gauging device. This consists of a rock-shaft 15 lying parallel to the above-mentioned plane, normal to the axis of the cylinder and carrying at its outer end a cross-piece 16 fitted with two feeler pins 17. The inner end of the shaft carries a saddle 18 supporting a pointer 20, the end of which has a hole engaging from below the pointed end of a screw 19. When the device is properly assembled in the cylinder, the pointer is at zero and the uppermost generator lines of the pins 17 are in the normal plane to the axis previously mentioned. If now the end having the acute angle is depressed until the gap in the ring is closed, the shaft 15 will rotate and the pointer 20 indicate the width of the gap. The pointer reads at either side of " zero " to enable both right and left cut rings to be gauged. Square cut rings are gauged by using a frame 13 which merely acts as a support together with the usual gap gauges. In a modification, the ring is held in the normal plane and only one end depressed, this end moving a spring-pressed feeler connected to indicating mechanism.
