Title: Improvements in and relating to gas fired water heaters
IPC: F23N1/08
Filed: 1933-05-01
Abstract: 411,274. Geyser valves. EWART, J. H., 26A, North Audley Street, London. May 1, 1933, No. 12687. [Class 135.] In a gas-fired water heater, a valve 5 for controlling the flow of gas to the main burner 1 can only be opened when water is actually flowing to the heater and the jet of the pilot burner 8 is alight. The flame of the burner 8 impinging on a bi-metallic thermostat element 9, anchored at 10 and having its free end engaging a slot in a belt crank lever 12 pivoted on a bracket 14, causes the element 9 to expand outwardly and the lever 12 to move a doublearm lever 16, pivoted at 17 on a tubular member 19, beneath an actuating member 25 for the gas valve 5. The lever 16 is urged against the member 25 to open the gas valve by an actuating- member 24 projecting from a water-flow device 20 comprising a valve 21 urged upwardly when water is admitted to the inlet 22 by a control cock (not shown). The pivot 17 is arranged to allow a certain amount of pivotal motion in a horizontal plane. The actuating members 24, 25 operate their respective valves in the manner described in Specification 411,276. Failure of the gas supply releases the lever 16 at once from the member 25 so that the valve 5 is yieldingly urged to its seating, where it remains until the water supply has been cut off, the burner 8 re-lit, and the water supply turned on again. Failure of the water supply alone causes the valve 5 to close until the supply is restored. The lever 16 has a counterweight 26 to prevent sticking. A gas cock 6 is provided on the inlet side of the valve 5. Preferably an additional pilot tube 7 is provided for the main burner so that the thermostat 9 may be arranged away from the main burner.

Title: Improvements in scraper conveyors
IPC: B65G19/28
Filed: 1949-05-13
Abstract: 665,661. Endless-chain scraper conveyers. HOUILLERES DU BASSIN DU NORD ET DU PAS-DE-CALAIS. May 13, 1949. [July 16, 1948] No. 12779/49. Addition to 651,908. Class 78 (i). The invention consists in modifications of the conveyer disclosed in the parent Specification. Framework. Figs. 1, 2, 6, 7. One of the gusset plates d of each pair is replaced by a member c which projects beyond the plane of contact of the assembled elements, the projecting part being shaped as shown, Fig. 1, to permit horizontal and vertical swinging of the elements relative to one another. Each member c has in addition a sloping face c<SP>4</SP> while a similar sloping face d<SP>2</SP> is provided on a bracket secured upstream of the gusset plate d so that mining machinery which may rub against the side of the conveyer is deflected away from the joints. Side plates for increasing the trough depth may be secured to the sections by means of the tapped holes c‹ and d<SP>4</SP>. The members c are secured to the flap b<SP>1</SP> which is shaped such that the upper surface comprises two parts b<SP>3</SP> and b<SP>5</SP>, the former being curved to an arc having the point O<SP>1</SP> as centre and the latter being straight and inclined at an angle a/2 to the horizontal, where a is the maximum angle between sections in the vertical plane which the sections can assume. A tapered member b<SP>2</SP> is secured to the downstream end of each section, this member also extending slightly beyond the plane of contact OO<SP>1</SP> of the sections. The upper surface of each member b<SP>2</SP> is inclined at angle a/2 to the horizontal and its lower surface is curved to an arc having the point O as centre, this lower surface co-operating with the surface b<SP>3</SP> of the flap b<SP>1</SP>. The guides i, k and l are as in the parent specification. Guides k, however, may be of resilient material or may be formed as spring blades, thus preventing jamming of the scrapers. Each of the sloping surfaces of the guides i, k and are inclined at angle a/2 to the horizontal. At the downstream end of each element a bar a' is secured which is bent downwardly at the angle a. Thus it is only necessary to support one of the adjacent ends of two adjacent sections as the other adjacent end is supported by either flap b<SP>1</SP> or by the bar a<SP>4</SP>. Transverse members a<SP>2</SP> are provided for supporting the elements. The surfaces c<SP>6</SP>, c<SP>7</SP> and c<SP>8</SP> of the members c limit the angular adjustment of the sections and so determine their maximum values. Push-plates. Figs. 10 and 11. The pushplates e have forward sloping faces e<SP>1</SP> and are attached to a bracket e<SP>3</SP> at each end by a pin e<SP>2</SP> engaging a slot in the bracket, the brackets being mounted on the parallel chains f. The slotted connection allows the push-plates to take up a slanting position with respect to the chains.

Title: Improvements in Temperature-Controlled Expansion Valves
Inventor: FLITSCH ERNST
IPC: F25B41/06
Filed: 1968-03-15
Abstract: 1,192,695. Valves. E. FLITSCH. 15 March, 1968 [15 March, 1967], No. 12841/68. Heading F2V. [Also in Division G3] A temperature-controlled expansion valve for a refrigerator has two coaxially interposed contacting sleeves 9, 10 controlling the flow of refrigerant from an inlet 2 to an outlet 3 leading to the evaporator. Each sleeve is formed with peripheral ports 15 whose degree of overlap varies the flow through the valve. The inner sleeve 10 is rigidly connected to a tube 27 which is moved axially through a tappet 43 by a diaphragm 5 responsive to the pressure in a temperature sensor and the pressure in a chamber 6 that is connected to the evaporator exit by passage 19 or to the outlet 3 by passage 4. The outer sleeve 10 is rotatable by a gear 22 on a shaft 21 carrying a control knob 20 and meshing with a gear 18 fast with the sleeve, a pin 24 preventing axial movement of the sleeve 10. In order to seal the space within the sleeves from the inlet when the refrigerator is closed down, a spring-loaded piston 29 sits on the end of the outer sleeve 9, the piston normally being held in the position shown by the high inlet pressure acting on the end of the piston. A capillary tube 30 connects the inlet with the interior of the piston which is maintained at the pressure of the outlet 3 by the connection through tube 27. The upward movement of the diaphragm on the result of close down causes due to the abutment of the inner sleeve on stop 48, a closure member 37 on the end of rod 35 having a flange 40 to close the outlet end of tube 27 allowing the pressure to rise inside the piston 29 and so moving it down to seat on the end of sleeve 9. The upper part of the valve casing may be rotated relatively to the lower part to cut off communication of the chamber 6 with the outlet 3.

Patent GB-855751-A (GB)
Title: A process for the preparation of aromatic dicarboxylic acids
IPC: C07C51/487
Filed: 1959-04-16
Abstract: Aromatic dicarboxylic acids are prepared by a process wherein oxygen or a molecular oxygen-containing gas is passed through a solution of an aromatic compound (i.e. any aromatic compound which can be oxidized to an aromatic dicarboxylic acid with the formation of formic acid as a by-product) in acetic acid in the presence of a heavy metal compound as catalyst, formic acid is removed from the mixture comprising reaction product, acetic acid, formic acid and water by selective decomposition of the formic acid, and the acetic acid present in the mixture is returned to the oxidation zone after removal of the formic acid.  The selective decomposition of the formic acid is preferably effected in the presence of oxygen by means of a catalyst, such as platinum, iridium, osmium, ruthenium, palladium, rhodium, aluminium oxide and copper chromite, with or without a carrier. The mixture from which formic acid is removed may be vaporous or liquid and may contain aromatic intermediate products. Examples of liquid mixtures are condensates of the vapours from the oxidation zone and mother liquors from which the dicarboxylic acids are separated.  The liquid mixture which contain aromatic intermediates may be partially evaporated and the vapours treated to decompose formic acid, the unevaporated portion being recycled. Specified starting materials are alkyl- or acyl-benzoic acids and dialkyl-benzenes.  The processes of the invention, and prior art processes are described in detail.  Specification 737,439 is referred to.

Abstract: 951,708. Orientating metal inserts. GROOV-PIN CORPORATION. April 6, 1962 [Oct. 9, 1961], No. 13337/62. Addition to 944,668. Heading B8S. A control system is provided for operating the device shown in the parent Specification which orientates inserts. Inserts fall from magazine 62 into aperture 19 formed in feed plate 12 operated by fluid cylinder 49. The cylinder is caused to move left or right according to whether the insert bridges the contacts 35. Thus, inserts of one orientation are taken to the left and are discharged and inserts of the other orientation are taken to the right by feed plate 12 and then discharged. The two orientations are thus separated. The control system includes three cams 71, 72 and 73 carried by shaft 74 driven by motor M. The cams control respectively switches 71<SP>1</SP>, 72<SP>1</SP> and 73<SP>1</SP>, the current being supplied at 75 and 76. The fluid cylinder 49 is controlled by valves 77 and 78 which are operated by magnets 86 and 87 included in the electrical circuit. The magnets are controlled by relay 91 which is provided with arms 92, 93 and 94 simultaneously operated by coil 95 thus making or breaking contacts a-a<SP>1</SP> to f-f<SP>1</SP>. Cylinder 49 operates switch 61 via finger 55 carried by plate 12. Operation.-When contact 35 is made by an insert of the first orientation, coil 95 is operated to move relay 91. At the same time motor M starts, and shaft .74 commences to rotate. Firstly cam 71 operates to close switch 71<SP>1</SP> to hold the circuit. Then cam 72 operates to close switch 72<SP>1</SP> which operates magnet 86 to rotate the valve 77 to cause the fluid cylinder to move feed plate 12 to the left to discharge the insert to the left shoot. The cylinder returns rightwards and comes to rest at its original point when finger 55 strikes switch 61. Again, when the insert is in the second orientation, motor M starts but switch 35 fails to operate. The cams therefore rotate in the same manner, but the effect is that magnet 87 is operated to move the feed plate to the right to discharge the insert there; and then magnet 86 is operated to return the feed plate leftwards to the original position. In this way, the circuit controls the movement of the feed plate to separate the inserts in the two orientations.
