Title: Improvements in or relating to viscosity compensators for hydraulic shock-absorbers
IPC: F16F9/14
Filed: 1952-01-31
Abstract: 711,644. Hydraulic shock absorbers. GIRARD, A. A. L. Jan. 31, 1952 [Feb. 8, 1951], No. 2607/52. Class 108(3) A compensator for viscosity variations in an hydraulic shock absorber comprises a rectilinear bi-metallic strip 5 secured edgewise by one of its ends to the wail 1 of a compression chamber, and carrying a light plate 7 at its other end which obturates an escape aperture 4. In operation, a temperature change results in a tendency for the strip 5 to bend and move the plate 7 in relation to the aperture 4. The movement occurs during low pressure phases in the compression chamber when there is thus no great friction between the plate 7 and the wall 1. In the rotary damper shown in Fig. 6, two vanes 17, 18 rigid with an operating shaft 16. each carry a non-return disc valve 25 ccntrolling flow through three ports 27. The vanes 17, 18 together with a bame 20. define working chambers x, y and z. Also passing through each vane 17, 18 is a port 4, Fig. 3, controlled by a plate 7 carried by a bimetallic strip 5 secured to the vane at 6. In the modification shown m Fig. 9 the port 4 is formed in the valve 25 in alignment with one of the ports 27. The plate 7 and strip 5 are carried by the valve. Instead of the plate 7 being profiled as at 11, it may completely cover the port 4 and may itself be formed with a suitably shaped port to co-operate with the port 4, Fig. 4, (not shown). A non- return valve may be disposed at the end of the port 4 opposite to that at which the plate 7 is mounted. The orifice 4 may also be of square, triangular, or elliptical cross-section. The bimetallic strip may be of V, U, semi-circular, or spiral shape. The plate 7 may control flow through more than one port. The plates 7 and associated ports 4 may be disposed in the baffle 20. Chambers x, z and y, z are connected by respective restricted passages 28, 29. Chambers x, y are connected by a passage 30 having an adjustable restriction 31. The invention is applicable to rectilinearly-acting dampers.

Title: A pneumatic memory device
Inventor: FEDOSEEV ROBERT JURJEVICH
IPC: F15B21/00
Filed: 1964-01-23
Abstract: 1,056,244. Fluid-pressure servomotor systems. NAUCHNO-ISSLEDOVATELSKY INSTITUT TEPLOENERGETICHESKOGO PRIBOROSTROENIJA. Jan. 23, 1964, No. 2927/64. Heading G3P. A pneumatic memory device is adjusted by a pressure P3 to be memorized and thereafter supplies this pressure to an outlet P4. Initial adjustment is effected in response to a control pressure P1 which raises a diaphragm 12 to release a locking device 9 to permit axial movement of a spindle 6. The pressure P1 also acts in a chamber 25 to cause upward movement of a triple-diaphragm assembly to close a port 22 and open a port 24 so that the pressure P3 can pass into the outlet P4 and gain access to a chamber 14 surrounding a spring-loaded bellows 2 the free end 4 of which thereupon takes up a position corresponding to the pressure P3 . When the control pressure P1 is removed the spindle 6 is again locked by the device 9 and the triple-diaphragm assembly is moved down by loading pressure in a chamber 26 so that the outlet P4 is cut off from the pressure P3 and is connected through the port 22 to an atmospheric bleed 21. The consequent reduction of pressure in the outlet P4 allows the bellows 2 to expand to bleed air past a ball valve 7 which is connected by a flexible tube 33 with a chamber 15 having a restricted connection 18 with a pressure supply P2. The lowering of the pressure in the chamber 15 causes a diaphragm 16 to open a port 20 and supply pressure from P2, through the ports 20, 22, to the outlet P4 to maintain the pressure acting externally on the bellows 2 and at the outlet P4 at the value corresponding to the locked position of the spindle 6.

The whole assemblage of frames and plates is sprayed with metal by means of a spray gun and the frame finally stripped from the plates.  According to the Provisional Specification the masking frame may also be of shellacked paper, and the metal coating may be applied by cathode sputtering or electrolytic deposition.  Specifications 599,009 and 599,010, [both in Group XXXVI], are referred to.ALSO:The marginal edges of a condenser dielectric or other plate are initially masked by a frame secured thereto by an adhesive or sealing material, and a metal coating then applied by spraying, in order to ensure an even coating right up to sharply defined edges. The masking frame may be formed from a permeable material in which is absorbed a thermoplastic sealing material, e.g. paper impregnated with paraffin wax, and may be secured to the plate by heat and pressure.  For mass production, an apertured suction chest is used to locate and hold a number of plates (see Group III), and two apertured masking frames which may constitute a single sheet are secured to the two sides of the plates by means of a heated platen.  According to the Provisional Specification, the masking frame may also be of shellacked paper and the metal coating may be applied by cathode sputtering or electrolytic deposition.

Title: An improved process for the catalytic conversion of hydrocarbons
IPC: C10G11/18
Filed: 1950-02-10
Abstract: <PICT:0669711/III/1> In the catalytic conversion, e.g. cracking of hydrocarbons wherein the catalyst is separated from the conversion products and the oil-occluded catalyst passed through a stripping or drying zone and then through a regeneration zone while maintained as a fluidized mass, fluidization of the oil-occluded catalyst in the stripping zone is facilitated by the admixture therewith of hot dry spent or hot regenerated catalyst particles.  As shown, an oil feed stock containing suspended catalyst is subjected to cracking under pressure and elevated temperature in conversion coil 18 and the cracked oil-catalyst mixture is passed to fractionating tower 22 wherein the lower boiling fractions are removed at 27, 271 and the high boiling fractions with the catalyst are withdrawn at 28.  The catalyst-oil mixture is cooled at 30 and separated on the rotary or other filter 38.  The separated catalyst is passed by a screw or other conveyer 41 to a stripper or dryer 42 weherein the occluded oil is removed at 600 DEG -1000 DEG F. by the upward passage of a hot stripping gas, e.g. steam or the hot combustion gases from regenerator 44, from line 48, a controlled amount of oxygen-containing gas, e.g. air, being introduced at 50.  A fluidized catalyst bed is maintained in the stripper and the gases pass-off through separator 58 to vent 62. The dried or stripped catalyst is withdrawn through a standpipe 64 provided with fluidizing gas inlets 68 and is passed into regenerator 44 wherein the carbonaceous deposits are removed by the upward passage of an oxygen-containing gas at 1000 DEG -1150 DEG F. from lines 79, 80.  A fluidized catalyst bed is also maintained in the regenerator and combustion gases are withdrawn through separator 100, a portion being recycled through line 46 to stripper 42.  Catalyst from the regenerator is withdrawn and recycled to the regenerator through stand-pipe 92 and line 80, provided with heat-exchanger 98, a portion of the hot material being bled-off through line 70 and recycled to the stripper through line 48.  Alternatively, hot dry spent catalyst is withdrawn from the stripper 42 and passed to screw-conveyer 41 wherein it is admixed with the oil-occluded catalyst being fed to stripper 42.  Regenerated catalyst is finally withdrawn at 106 and cooled and slurried in feed stock, if desired, with the addition of fresh catalyst in drum 110. Various catalysts for the cracking of light or heavy naphtha, gas oil, overhead or distillate stock or mixtures thereof, are specified.
