Title: Improvements in or relating to refrigeration apparatus
IPC: F25D21/00
Filed: 1951-01-17
Abstract: 678,075. Thermal switches; snap-action switches. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Jan. 17, 1951. [Feb. 11, 1950] No. 1261/51. Class 38 (v). [Also in Groups XIII and XXIV] A defrosting control responsive to a predetermined number of refrigerator operations e.g. opening and closing of the door, comprises a switch blade 58 for snap-action movement into two positions, one for normal working and the other for defrosting, and actuated by a sliding pin 34 which lies in the path of the free end of a spring 32 secured by a screw 28 to the switch housing and deflected by a cam 52 turned by successive door &c. operations. When the spring 32 is released by the cam it passes beyond its normal positions and moves the pin to snap the switch to the defrosting position. Each time the door is closed a slide 16 projecting from the switch housing 18 is pressed inwardly against a spring 50 and moves a pawl 40 to turn a ratchet wheel 22 carrying the wedge shaped cam 52. A dog 48 on the pawl prevents clockwise movement. The cam is thus gradually forced under the leg of the spring 32 and releases the spring after the predetermined number of operations. When defrosting is complete a thermostatic bellows 80 moves a pin 78 to snap the switch blade 58 to the position for normal working. The switch blade 58 has an inverted U-shaped slot 60 forming an upwardly extending tongue 62 the top of which is connected to the blade 58 by a C-shaped compression spring 64. The pin 34 acts on the tongue 62. Two doublefaced contact buttons 66 fixed to the upper end of the switch blade bridge either one of two pairs of contacts 70, 68 in the circuit of the refrigerator motor and an electric heater for defrosting respectively. For systems in which the refrigerating unit operates during the defrosting period the contacts 70 are omitted. A part 30 of the spring 26 retains the ratchet wheel 22 in place. The pawl 40 comprises an L-shaped spring 36 fixed at 35 and bowed at 39 to engage a cam surface 44 on the slider 16, the free end being notched to engage the teeth of the ratchet wheel.

Title: Improvements in the desulphurization of hydrocarbons
IPC: C10G65/08
Filed: 1928-01-14
Abstract: 315,439. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Jan. 14, 1928. Mineral and tar oils. purifying.-Crude hydrocarbons are freed from sulphur-bearing impurities by treatment in liquid or vapour form with hydrogen or gases containing the same in the presence of metallic sulphides which are stable under the conditions of working employed, namely, that no hydrogenation will occur by operating at temperatures between 200‹-300‹ C., and simultaneously keeping the pressure applied lower than that at which hydrogenation occurs. The catalysts may be used alone, or admixed, or admixed with activators, such as compounds of metals of the 4th to 8th groups of the periodic system, especially their oxides, and if desired, deposited on carriers, e.g. pumice or active charcoal. The purified hydrocarbons may be employed in other catalytic processes, e.g. hydrogenation, a poisoning of the catalysts being avoided. In an example, benzene containing organic sulphur compounds is - mixed with sufficient hydrogen for desulphuration and subsequent hydrogenation, and passed over a mixture of molybdenum sulphide and cobalt oxide in equimolecular proportions at a temperature of 300‹ C. and under 60 atmospheres pressure. The pressure is decreased to 10 atmospheres, and the gases freed from sulphur compounds by washing with 60 per cent caustic soda solution at 100‹- 120‹ C. They are then passed over a hydrogenation catalyst. Alternatively, the hydrogen for hydrogenation may be added after the removal of sulphur. Other examples are given. Specification 258,576 is referred to.

Filed: 1925-01-16
Abstract: 227,858. Westinghouse Electric & Manufacturing Co., (Assignees of O'Brien, B.). Jan. 16, 1924, '[Convention date]. Void [Published under Sect. 91 of the Act]. Low - pressure metallicvapour apparatus; vacuum tubes.-A discharge tube in which the current is carried by a stream of electrons emitted from a cathode is provided with means whereby the anode is caused to emit positive ions. For this purpose a substance such as caesium may be inserted in an exhausted bulb, and the anode heated to a temperature at which caesium atoms striking it are evaporated as positively-charged caesium ions; the adsorbed film of caesium produced on the cathode also improves the electron emissivity. The arrangement enables lower voltages to be used between the electrodes. Tungsten is a suitable metal for the electrodes. As shown, a cylindrical cathode 21 is mounted around a control electrode 19, preferably of tungsten, and an anode consisting of a metallic core 16 with a winding 17 and a cylindrical cover 18. The bulb is exhausted and is in communication with a side tube 9 containing caesium 11. The anode is heated inductively by the winding to a temperature above the critical temperature at which the Richardson work function exceeds the ionizing potential of caesium. The cathode is heated by radiation from the anode. In another arrangement une cathode and anode consist of filaments, and the anode is heated to a higher temperature than the cathode which is only slightly heated.

IPC: G01N3/42
Filed: 1926-01-18
Abstract: 263,636. Dunlop Rubber Co., Ltd., and Simpson, E. Jan. 18, 1926. Testing hardness of materials.-Relates to apparatus of the type employing a spring- loaded penetration member operatively connected to registering means, the spring opposing the pressure of the specimen, and consists in giving the spring a great initial compression. The lower part of the device is formed as a cylinder 1 which is connected by a stem 3 to a handle 2. Slidably mounted in the cylinder is a piston 4 retained by a spring washer 5 and provided with an extension 6 of small diameter which positions as the penetration member. A flange 7 is adapted to contact with the specimen when the maximum penetration has been achieved. The piston is preferably hollow to provide an anchorage for a compression spring 9, the other end of which is anchored to an abutment 10. In use the device is placed on the vulcanized rubber or like to be tested and pressed into the material until the latter is engaged by the flange 7. The movement of the piston is transferred by engagement of the piston with a pin 16 on a sliding rack 11 and hence to a pinion 13 and pointer 14 moving over a scale. A plate spring 18 retains the rack in the position reached. A spring plunger 19 serves to reset the rack.

Title: Boilers
IPC: F23J1/00
Filed: 1954-01-25
Abstract: 773,693. Clinker removal from boilers. SMITH, W.H. Jan. 18,1955 [Jan. 25, 1954; April 29, 1954; July 15, 1954], Nos. 1426/55, divided out of 771,921, 12504/54 and 20719/54. Class 51 (1). A boiler having water spaces 2, 3 has a central fuel hopper 4 below which is a water space 5 extending from front to rear of the boiler and presenting surfaces 6 upon which fuel falls before its delivery to firebars 7. Associated with each set of bars 7 is a reciprocable clinker ejecting ram 8 operated periodically in accordance with the time the forced draught fan for the boiler has been operating by the oscillation of a motor 15 driven shaft 11. Each set of five bars 7 is adjustably supported at one end on a channel member 17, whilst at the other end the bars are spring-supported, a channel member 20 on which they rest being subjected in an upward direction, through the agency of a bell-crank lever 22, to the force of a spring 26. The ram 8 associated with the bars is thus pressed against the boiler wall, so limiting the leakage of air into the boiler in that region. Members 28, adjustable vertically on the hopper walls, control the depth of fuel bed. When the rams 8 are operated they push clinker on to crusher rolls 30. These comprise projections 31 mounted on shafts 32 which are geared by pinions 34 and chain-drive 35 to a motor 36 which only operates when either of the ram motors 15 is operated. The chamber 33 having the rolls 30 is closed, when the rolls are stationary, by a slide 37 which is operatively connected to one of the rolls by means comprising rack 38, quadrant 39 and rod 41 such that when the rolls are rotated the slide is withdrawn to allow the crushed clinker to fall on to a bucket conveyer (not shown) which also operates when the rolls are operating. Primary air is supplied by a fan 45 to an inlet 46 below the water space 5. Combustion products pass through fire tubes 27 in the spaces 3 to flue spaces 47 from the rear of which they pass to an outlet 48. Fly-ash &c. drops into a chamber 50 from which it may pass to the ash pit through a flap 51. Operation of the flap 51 for this purpose cuts off the air supply from the fan 45. The air supply may also be cut-off automatically every time either one of the rams 8 is used. Secondary air is supplied through hand controlled (handle 55) slots 52. Fuel is supplied to the hopper 4 by a conveyer (not shown) which is controlled by a member 56 mounted so as to lift and operate a " conveyer stop switch " when the fuel level rises and to fall and operate a " conveyer go switch " when the fuel level drops.

Abstract: 353,825. Loom dobby and take-up driving mechanism. WOOD, A. E., Dobcross Loom Works, Dobcross, Yorkshire. -(Crompton & Knowles Loom Works; Worcester, Massachusetts, U.S.A.) Jan. 16, 1931, No. 1481. [Classes 142 (i) and 142 (ii).] In looms having a head motion or dobby driven by an upright shaft 19, operation of a single handle 30 causes the shaft 19 to be unclutched from its drive by a lever 61, 64, 68 and simultaneously causes the take-up drive 24, 25, 27 to be reversed by a lever 41. A sub-control handle 66 may be turned to unclutch the shaft 19 without reversing the take-up. By means of a pin 21 fixed to a slide 22 a collar 20 fixed to the shaft 19 is normallv driven by a bevel gear 18 loose on the shaft but driven by bevel and eccentric gearing from the crank shaft 11. The take-up is driven from a shaft 28 having a bevel gear 27, which is normally driven by the bevel gear 24 so that the take-up mechanism is driven forwardly. When the lever 30 is moved to the position shown on dotted lines, its upper end operates mechanism for reversing the pattern chain drive, whilst its lower end operates adjustable lever mechanism 51, 45 and through a give-way device rocks a lever 41 which raises a sleeve 23, whereby the bevel gear 25 is brought into gear with the gear 27 and the take-up drive is reversed. The lever 45 by means of a slotted link 72 operates the three-armed lever 61, 64, 62, whereby simultaneously the slide 22 is raised and the operating pin 21 is withdrawn from the driven gear 18, thus stopping the driving of the shaft 19. Operation of the sub-control lever 66 rocks the lever 61, 64, 68 by means of an adjustable connector 65, but owing to the lost-motion connection 69, 70 does not rock the lever 41.

Title: Improvements in the manufacture and production of fertilizer salts
IPC: C05B7/00
Filed: 1929-01-16
Abstract: 329,641. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Jan. 16, 1929. Manures.-Fertilizing-salts or mixtures of salts suitable as fertilizers are obtained by double decomposition of salts of strong mineral; acids in a medium of liquid ammonia or by treating mixtures of salts with gaseous ammonia. The mixture of salts may be freed from ammonium or the separate salts may be isolated. Other fertilizing substances or salts which absorb ammonia such as ammonium nitrate or alkaline-earth chlorides may be added. In examples, sodium chloride is treated at about 100‹ C. in a closed vessel with a solution of ammonium nitrate in liquid ammonia. The solution may be separated by filtration from excess of sodium chloride, and is evaporated to yield a mixture of sodium nitrate ammonium nitrate and ammonium chloride, or is cooled to separate crystals of sodium nitrate. Potassium chloride is shaken at 0‹ C. with ammonium nitrate dissolved in liquid ammonia, and yields a solid residue of potassium nitrate and a solution of ammonium chloride. Dipotassium phosphate is treated with ammonium nitrate dissolved in liquid ammonia. After evaporating off the ammonia, a mixture of di-ammonium phosphate and potassium nitrate remains. Mono- or di-potassium phosphate mixed with ammonium nitrate is treated with gaseous ammonia yielding mixtures of ammonium phosphate and potassium nitrate. Gypsum is stirred at room temperature in a solution of ammonium nitrate in ammonia. Solid ammonium sulphate is precipitated. The solution of calcium nitrate may be evaporated or may be treated with carbon dioxide to precipitate calcium carbamate.

Abstract: 970,722. Tube-type heat exchangers. P. LEGRAND. Jan. 13, 1961 [Jan. 22, 1960], No. 1573/61. Heading F4S. A heat exchanger comprises a casing (not shown) containing a nest of straight tubes such as T 3 , T 4 , T 5 , having transverse fins 8, and arranged in polygonally-shaped groups (Fig. 1), guide plates P fitted on each tube groups and so shaped to comprise at least one discontinuous helical surface winding about the tube axis and imparting a transverse gyratory motion to the external fluid g, thus forcing it between the tube fins 8, each guide plate P being of polygonal shape with cut-out portions to fit the tubes of a group (see Fig. 4, not shown). As shown, the baffles may be omitted from the tube group at the centre of the nest and, to provide for uniform flow resistance in all the tube groups, these latter tubes t 1  may be larger and more closely spaced than the remaining tubes. The pin shape and spacing may be such that, according to Fig. 5, two complementary vortices j and k rotating in opposite directions are formed between adjacent fins. The tubes of each group may lead to an intermediate header and all the intermediate headers may then lead to a main header (Fig. 1, not shown). Alternatively, all the individual tubes may connect directly to the main header.

Abstract: 927,572. Valves. FAIREY CO. Ltd. Jan. 5, 1960 [Jan. 15, 1959], No. 1579/59. Class 135. A valve 10, Fig. 1, controlling fluid flow to a double-acting jack connected to delivery passages 11, 12 in the jack body 13, is mounted on the latter, and includes a pair of platens 15, 16 having opposed, parallel plane bearing-surfaces 17, 18, polished to a standard optical flat and spaced by rings 19 similarly polished. Platen 15 has a central inlet port 20 connected to a high-pressure inlet 22, and alternative delivery ports 23, 24 connected to passages 11, 12 respectively; the platen 16 is provided with alternative delivery ports 29, 30, also connected to passages 11, 12 respectively, and situated opposite ports 23, 24. The closure member is in the form of a slide 35, Fig. 3, comprising an annular sleeve mounted between the platens to move perpendicularly to the sleeve axis, the annular end faces of the slide 35 constituting bearing surfaces. When the slide is moved in either direction from the closed position shown it progressively uncovers one of delivery ports 23, 29 or 24, 30, Fig. 1, to connect them with the inlet 22 via the central opening in the slide, and at the same time closes the other pair of delivery ports. The slide 35 has end lugs with keyways by means of which operating and balancing spindles 39, 40 are attached thereto, and a return passage, not shown, is connected to the annular spacer 45 outside the slide but between the platens. Each annular end surface of the slide is formed with a circumferential band 50, Fig. 3, of 50-60 micro-inches depth leading to a step 52 of 0.052 inch radial width, the distance across the steps 52 at each end of the slide being less than the height of the rings 19, Fig. 1, so that the slide has a limited end float between the platens. In use there will be a continuous seepage of fluid outwardly across the bands 50, 52, Fig. 3, between the slide and the platens and draining into the spaces 45, so providing a lubricating film and on which the slide floats and producing a self-centering action tending to return the slide to its central position between the platens. Any foreign bodies in the fluid enter the relieved bands and give rise to an hydraulic force which lifts the slide and increases the effective gap between the platen and trapped body whereby the latter may be forced into the space 45. The step 52 may also incorporate an outer relieved band 54. In another form the delivery ports 71, 72, Fig. 6, in the upper platen are blind and communicate with the two delivery ports 73, 74 in the lower platen via cross bands 75, 76 in the slide so balancing the hydraulic forces acting on the two ends of the slide and by seepage across the blind ports 71, 72, increases the total flow through ports 73, 74. Each end face of the slide is provided with a pair of inset arcuate relieved bands. The slide may be replaced by a piston closure of dumbbell shape.
