Title: Process for the hydrogenation under pressure of distillable carbonaceous materials
IPC: C10G1/08
Filed: 1932-09-24
Abstract: The production of hydrocarbons by the heat treatment of distillable carbonaceous materials with hydrogenating gases under pressure is carried out in the presence of organic sulphonic acids together with metals or their compounds of groups 4--8 of the periodic system.  The sulphonic acids may be added before or during the treatment and, when applied to materials having a basic or alkaline reaction, are added in sufficient quantities to neutralize at least partly the alkaline constituents.  Other neutralizing agents, e.g. acids may be added, e.g. by soaking therewith active carbon, silicic acid, pumice stone &c. and supplying these materials to the reaction chamber.  Examples are given of the treatment at 450 DEG  C. and 200 atmospheres of finely divided brown coal soaked with a mixture comprising equal parts of benzine, sulphonic acid and molybdic acid, and of a distillation residue mixed with 1 per cent of small coke soaked with molybdic acid which is preheated to 470 DEG  C. and then admitted to the reaction chamber in admixture with sulphonated paraffin.ALSO:The production of hydrocarbons by the heat treatment of distillable carbonaceous materials with hydrogenating gases under pressure is carried out in the presence of organic sulphonic acids together with metals or their compounds of groups 4--8 of the periodic system.

Abstract: 1506188 Hydraulic reciprocating pumps and motors VOITH GETRIEBE KG 23 June 1975 [22 June 1974 24 May 1975] 26612/75 Heading F1A A radial piston pump or motor comprises a casing 10, 1a, 11b mounting a control pintle 38, 39, 40, a cylinder block 13 rotatable on the pintle part 38, pistons 16 reciprocable in respective radial bores 15 in the block 13, a piston guide ring 20 rotatably mounted in the casing and having an inner periphery 21 composed of flat surfaces each contacted by a shoe 17 on the outer end of a respective piston, and opposed surfaces 42, 46 on the pintle part 40 and casing, respectively, the surfaces being separated by a hydrostatic bearing pad 50 and being positioned so as to oppose the force R representing the resultant of the hydrostatic forces acting on the pistons during operation. In the embodiment shown the pintle part 40 is rectangular in cross-section, the surface 42 and an opposed surface 43 thus being planar whereby the pintle is slidable between casing surfaces 46, 47 to adjust the eccentricity e between the axes 14, 25 of the pintle and guide ring 20. A bolt 60 movable by a handwheel or hydraulic cylinder causes movement of the pintle against a spring-loaded plunger 61. In a second embodiment, Figs. 7 and 8 (not shown), the pintle part 40 is cylindrical and is eccentric with respect to the part 38, whereby angular adjustment of the pintle changes the eccentricity e. Working fluid flows into and out of the bores 15 through slots 34, 35 in the pintle, the slots being connected by bores 36, 37 either to radially opening inlet and outlet ducts 18, 19 (as shown) or axially opening ducts, Figs. 6 and 7 (not shown). The resultant force D on the pintle due to the pressure in the ducts 18, 19 acting with the forces R, E produces only a slight turning moment on the pintle. The force D acts in an axial direction in the embodiment with axially opening ducts and is resisted by pressure pads (74, 75) between the surfaces 44, 48 of a flange part (139) of the pintle. A pressure pad 54 loads the pintle axially. Drive is transmitted between the guide ring 20 and a shaft 30 by a drive disc 32. Hydrostatic bearing pads 28 are provided for supporting the guide ring 20 in the casing 10.

Abstract: 789,659. Making turbine and like blades. GENERAL MOTORS CORPORATION. Aug. 31, 1956, No. 26657/56. Class 83 (2). A metal turbine or like blade having curved faces is made by machining one face 27 of a blank B, Fig. 2, bending the blank to shape the machined surface 28, Fig. 9, so that over its entire area its distance from an assumed reference surface 36 corresponds to the desired thickness of the finished blade, machining the opposite face 34 of the bent blank to the reference surface 36, and then bending the blank to form both faces 25, 26, Fig. 12, to the desired blade contour. The starting blank B, Fig. 2, having a blade portion 21 and root portion 22, may be trimmed from a rolled blank A, Fig. 1 (not shown), produced by hot rolling in gap rolls; alternatively the blank may be cut transversely from rolled or extruded strip having a thickened edge or it may be formed by upsetting. This blank may taper longitudinally. The surface 27 is machined by milling which may also be used to produce a longitudinally tapered blank. After annealing the blank is bent cold in dies to form a curved blank D, Fig. 6 (not shown). This blank has its root milled to length and the sides thereof rough machined and the second face 34, Fig. 9, is then machined by milling. The resulting blank E is annealed and then cold bent and twisted between dies 41, 42, Fig. 12, to the finished blade contour. This bending may or may not deform the root. The latter is subsequently finish-machined and the blade is then polished and heat treated. The machined surfaces 27, 36 are preferably plane but may be cylindrical or conical. The dies may bend the blade in two directions if desired.

Abstract: 468,420. Helical springs. CORNIERE, P. Sept. 28, 1935, Nos. 26862, 26863, and 26864. Void. Convention dates, Oct. 1, 1934, April 5, 1935, and July 11, 1935. [Class 108 (iii)] [Also in Group XXIV] Relates to a helical spring for use, for example, in rotary force-transmitting devices and constructed by cutting helical slots in a tubular member. As shown in Fig. 1, the coils are of trapezoidal cross-section and the walls of one of the slots 1 gradually come together along a line 5 at their ends 4, 4<1>, thus providing unbroken end faces 7, 8 for attachment to adjacent parts of a transmission device. Fig. 7 shows such a device having one portion formed as a spring in accordance with the invention. In another construction, Fig. 10, the coils 12 are of stepped formation in cross-section. Fig. 14 shows a spring in which the width of the rectangular-section coils d increases from the centre to the ends. In modified forms of this last construction, the coils have substantially triangular sections or sections as shown in Fig. 10. In a further construction of a spring having triangular section coils, the outer periphery of the spring is curved inwardly instead of the inner periphery being curved outwardly, as shown in Fig. 14.

Title: Improvements relating to refrigerators
Inventor: FURY CHARLES EDMUND
IPC: F25D17/04
Filed: 1961-07-25
Abstract: 1,026,533. Refrigerators. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 23, 1962 [July 25, 1961], No. 26910/61. Heading F4H. A refrigerator comprises a lower main storage compartment and an upper compartment containing air evaporator 4, a manually adjustable thermostat 11 for controlling the temperature of the evaporator, and an adjustable damper 21 located in a restricted passage 33 between the upper compartment and the main storage compartment, adjustment of the damper being effected in conjunction with adjustment of the thermostat. The arrangement is such that when the thermostat is set to its coldest position the damper is open and is progressively closed as the thermostat control is moved to its warmest setting. As shown, natural circulation passes air from the main compartment through passage 32, over the evaporator, through restricted passage 33 and back to the main compartment via wire grid 27. Passage 33 is controlled by damper 21 in control box 10, which in turn is controlled by cam 18 mounted on spindle 17, e.g. of plastics material, which is pressed on to the thermostat spindle, both being shaped, e.g. of D-shaped cross-section, to prevent relative movement. The outer end of spindle 17 passes through the front of control box 10 and carries a control knob 20. The wire grid 27 protects lamp 28 which gives illumination to transparent indicating inserts 24 arranged round the control knob (Fig. 3, not shown). A coloured sector disc 19 is mounted on spindle 17 and serves as an indication of the position of the spindles. The disc is of such a width as to cover partially two indicating inserts 24 at once (Fig. 3, not shown). This ensures that the user turns the control knob to the fully off position in which case no coloured light is transmitted to the penultimate insert. In a modification (Figs. 6 and 7, not shown) the control box is situated at the side of the upper compartment and communicates therewith through a damper controlled hole in a separating wall. In this arrangement the damper is held against the cam by a spring.

Abstract: In the zone refining or crystal pulling of silicon in a quartz crucible, the crucible is provided with an aperture through which refined and/or residual silicon is forced under pressure in the molten state after the zone-refining or crystal pulling operation. The aperture may have a diameter of 1/16 -\ba3/32 inch. As shown in Fig. 1, a rod <PICT:0886976/III/1> <PICT:0886976/III/2> 4 of silicon is withdrawn in an atmosphere of wet hydrogen from a molten mass 3 of silicon in a quartz container 1 having an aperture 1a.  The gas pressure is then increased and residual silicon is forced through the aperture 1a, a cooling chamber 12, a gas lock 19, and a further cooling chamber 21 in which it is collected either as individual pellets or as a solid rod of substantially uniform composition.  The drawn rod may be remelted and the process repeated.  The finally produced rod may be remelted in the crucible and treated in the same was as the residual silicon.  As shown in Fig. 2, silicon is zone-refined in an atmosphere of wet hydrogen in a quartz crucible 101 having an aperture 110 by electric induction heating, after which the crucible and its housing 106 are turned through 90 degrees and the silicon progressively melted in fractions and forced through the aperture 110 and a gas lock 115 into a cooled crucible 109 of quartz or tantalum.  Each fraction may be collected in crucible 109 as above, i.e. as individual pellets or as a solid rod.

Abstract: 1,186,353. Storage circuits. ENGLISH ELECTRIC CO. Ltd. 4 July, 1967 [14 July, 1966], No. 27122/67. Heading G4H. A circuit arrangement for storing incoming signals on lead 14 (Fig. 1) in a second store 36 when the contents of a first store 10 are being read out to, for example, a printer 12 includes a control circuit 22 which enables a gate to the first register 10 when the printer is inoperative and enables a gate to the second register 36 when the printer is operating. In the embodiment described electrical pulses on lead 14 are normally fed through a gate 16 and an OR gate 18 to the counter 10. When the printer is operative the control circuit 22 enables a gate 30 so that the pulses on lead 14 are accumulated in the counter 36. When the printer next becomes inoperative the gate 16 is again enabled so that incoming pulses on lead 14 as well as being fed to the counter 10 are fed via a gate 42 (enabled when the counter 36 is storing a number other than one), a delay 46 and OR gate 18 to the counter 10 and also on lead 48 to decrement the counter 36. In this way each incoming pulse on lead 14 is accumulated twice in the counter 10 until the count stored in counter 36 whilst the printer was operative has been counted down to one. The enabling signal on lead 38 is then removed. The counter 36 comprises ten transistorized bi-stable circuits 301A . . . 301K (Fig. 2A) interconnected so that pulses on lead 44 successively render the light-hand transistor of the transistor pair in each bi-stable circuit non-conducting and the left-hand transistor conducting. Pulses on the lead 48 successively remove the pulses stored by the bi-stable circuit.
