Abstract: 438,904. Belt - tensioning pulleys. HADDAN, R., 31, Bedford Street, Strand, London.-(Western States Machine Co. ; Salt Lake City, Utah, U.S.A.) June 25, 1934, No. 18742. [Class 80 (i)] The spindle 7 of a resiliently-urged pulley 8 is universally adjustable, as for example by spherical washers 9, 10 and clamping nut 11, on a movable support 5.

Patent GB-918532-A (GB)
Title: Improvements in or relating to automatic telephone systems
Inventor: KEATING JOHN HENRY
IPC: H04Q3/00
Filed: 1958-06-13
Abstract: 918,532. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. June 1, 1959 [June 13, 1958], No. 18896/58. Class 40 (4). The invention relates to the adaptation of a junction relay set so that it can provide signals similar to those provided by a selector switch, so that when a preceding selector having facilities whereby it can step on if faulty outlet is seized, can do so not only when the outlet is to a selector but also when the outlet is to a junction. Such a step on selector relies on the reversion of a holding earth over the P-wire from the selected outlet, whereby the switching relay is held until a forward holding earth is provided from a preceding selector consequent upon the release of the holding relay when the switching relay operates. If the backward holding earth is not present the switching relay releases and the selector is stepped on. The Figure illustrates a junction relay set accessible from a 2nd- or 3rd-code selector of the type mentioned above. Idle- 100 V. battery is reverted over the P-wire. When such a selector tests the junction, its switching relay operates to this battery and applies a momentary lowresistance guarding earth to the P-wire. The selector also applies a calling loop over the junction and if the latter is in good order JA operates therein to the battery at the distant exchange. Rectifier MR1 isolates the second winding of JA so that its operation is not delayed. Relay JA reverts full earth on the P- wire to hold the switching relay and maintain the guarding condition. Relay JA operates slow-to-operate relay JB. Relay JA now releases slowly due to the short circuit of its lefthand winding. This release lag gives time for the forward holding earth from the 1st codeselector to be extended over the P-wire to hold JB. The latter is released when the calling party clears. If due to a fault no battery is present on the junction JA and JB fail to operate so that holding earth is not reverted on the P-wire and when the holding earth for the switching relay is momentarily removed the latter releases and steps on. If the junction conductors should be reversed, JA operates over its left-hand winding but immediately is counter-energized over its right-hand winding and releases before JB can operate. The consequent removal of the holding earth on P releases the switching relay in the preceding selector which thus steps on. The junction may be " busied out " by the insertion of an insulating peg in the jack BJ whereby JB operates to extend earth from the jack to the P-wire.

Title: Improvements in or relating to the manufacture of neutral ammonium sulphate
IPC: C01C1/249
Filed: 1921-07-16
Abstract: 187,320. Marr, J., and Coke Oven Construction Co., Ltd. July 16, 1921. Gaseous currents, materials carried by. - A process of drying granular material applicable to the manufacture of neutral ammonium sulphate, consists in conveying the material through a conduit within a section of which it is exposed to a current of hot gas, pneumatic action being used for introducing and withdrawing the material to and from the drying-section, while the material is conveyed through the drying-section mechanically. In carrying out the process for the manufacture of neutral ammonium sulphate, the crude salt is drawn by a fan H through a flexible feedconduit A having inlets a, c for ammonia and hot gas respectively, into an inclined rotary drier B and from the drier through a conduit C to a receiver D from which the dried salt is discharged through a rotary discharge drum, while the gas passes through a filter F and pipes J, K to an acid-bubble L, wherein the pyridine and ammonia are absorbed. The areas of the conduits and drier are such that the suction effect of the gas on the material within the drier is annulled. The material is deflected to the bottom of the drier by a baffle d co-operating with a fixed scraper or a ball-mill, and conveyed through the drier by shelves e which terminate at a distance from the end of the drier. The temperature of the salt within the drier is not allowed to exceed 80‹ C. When drying other material such as coal-dust, the bubbles are dispensed with, and the temperature within the drier may reach 100‹ C, the temperature of the hot gas being 200‹ C. Specification 9835/95 is referred to.

Title: A process for manufacturing hydrogen chloride
IPC: C01B7/01
Filed: 1947-07-18
Abstract: <PICT:0624974/III/1> p  Hydrochloric acid is produced by burning a mixture of hydrogen and chlorine in a metal combustion chamber, in an atmosphere of dry hydrochloric acid gas which may be a part of the product recycled after cooling and drying.  The ratio of hydrogen chloride to hydrogen-chlorine mixture may be from 0.5 to 3.0.  In the illustrated embodiment, the reaction takes place in a finned ferrous chamber 1, fitted with refractory burner 3 and explosion door 22. The chlorine and hydrogen, preferably oxygen free and dry, enter mixing chamber 5 through pipes 6 and 7 respectively; 4 is a gauze flame arrester.  The burner 3 of refractory material becomes incandescent and so maintains the flame.  The products pass through air cooler 11 and water cooler 12 and are scrubbed with concentrated sulphuric acid in tower 14.  A portion of the dry hydrogen chloride is recycled through pipe 19 either to the mixer as shown or to the base of the combustion chamber.

Title: Method and apparatus for treating textiles
IPC: D06M23/10
Filed: 1964-05-08
Abstract: 1,059,985. Textile treating apparatus. M. BOHLER & F. WEBER, [trading as BOHLER & WEBER KOMM GES]. May 8, 1964 [May 8, 1963], No. 19342/64. Heading D1L. In treating textiles with an organic solvent containing an emulsifier and dispersed water the solvent is circulated by means of a pump through a closed pipe-circuit directly to the treatment vessel and back to the pump and the emulsifier and water are added to the circulating solvent on the inlet side of the pump. With the apparatus shown, woven or knitted material to be milled is loaded through opening 14 into drum 12 and the door 15 closed. Programme controller 41 is started to energise motor M, which runs throughout the processing cycle, rotates the drum 12 and drives pump 13. Controller 41 also operates valve V 1  so that solvent flows from tank 24 to the washing housing 11, the quantity of solvent being regulated by a float control. Valve V 1  is then closed and valve V 3  opened, valve V 2  also being operated so that pump 23 may pump dry cleaning solvent from housing 11 and back to it in a closed circuit. Simultaneously with or shortly after the operation of valve V 3 , valve V 4  is opened in order to feed water and surface active substances from the addition device 33 to the solvent stream in the drain pipe 31, upstream of pump 23. The pump acts as a dispersing means producing a fine dispersion of the water in the solvent. The drum is then rotated at a low speed for about five minutes after which valves V 2  and V 4  are closed. Valve V 3  stays open and either valve V 5  or valve V 6  is opened. Solvent from the housing 11 is then pumped directly or via filter F to tank 24. After draining, valve V 5  or V 6  is closed, V 7  opened, clutch C operaed to drive the drum 12 at a higher speed and distillation unit D started. Liquid remaining in the textiles 13 is thus extracted by centrifugal force and pumped via valve 7 to distillation unit D. When the extraction is completed valve V 7  is closed and clutch C switched off so that the drum 12 again rotates at the lower speed in order to tumble the textiles 13. Valve V 8  is then operated to conduct a heated drying-air stream to the housing 11. While the textiles are drying, the solvent vapour containing air is conducted to the condenser of the distilling unit D where the solvent is recovered. At the end of the cycle, motor M is switched off and the textiles are taken out. The treating solvent may be heated by heater 42 under thermostatic control. In another embodiment continuous lengths of cloth are fed into and out of an open solvent container through which solvent is circulated. The temperature of the solvent is preferably maintained between 20‹ to 60‹C. and the weight of water used may range between 5% and 30% of the weight of textiles. A water-soluble or water-dispersible sizing or other finishing agent e.g. a commercial silicone-ester for abrasionresisting finish may be added with the emulsifier and the water.
