Title: Furnace for the combustion of domestic refuse and other inferior-grade fuels
IPC: F23J1/02
Filed: 1953-03-25
Abstract: 726,582. Refuse-consuming furnaces. VON-ROLL AKT.-GES., L. March 25, 1953 [April 26, 1952], No. 8239/53. Class 51 (1). A furnace for the combustion of domestic refuse &c. having a continuous and automatic cycle of operation comprises a pre-drying grate, a combustion grate, a clinker producing gas generator and a scraper chain which both supports the contents of the generator and continuously removes clinker therefrom. In the furnace shown, refuse from the hopper 1 passes to the pre-drying grate 3 and then falls to the combustion grate 5 from whence it passes into the gas generator 7 in which clinker is formed and the lower end of which extends into a water bath 12 for clinker quenching purposes. Drying is effected on the grate 3 by the hot gases arising from grate 5 and the generator 7. Additionally, gases from the grate 5 following the route 4 may be insufflated below the grate 3 or clean air may be blown up through the grate to produce combustion there also. Combustion upon grate 5 is effected by injecting into zone 6 cold or preheated air whilst combustion in the generator 7 is effected by injecting steam or air through the nozzle 88. Clinker from the generator is taken by a continuously moving endless scraper chain 10 to tipping wagons 17. At least one side wall 11 of the generator is inclined, preferably the rear wall as viewed in the direction of travel of the chain. The inclination of the wall or walls may be adjustable.

Title: Improvements in the manufacture of artificial filamentary materials of high bulk from copolymers of acrylonitrile and vinylidene chloride
Inventor: GREBBY JOHN WILLIAM
IPC: D01F6/18
Filed: 1956-03-16
Abstract: Voluminous artificial filamentary materials are produced by extruding an acetone solution of an acetone-soluble copolymer of vinylidene chloride and acrylonitrile in the form of filaments into an aqueous acetone coagulant, washing the filaments formed until they are substantially free from acetone, stretching the washed and dried filaments while in a softened condition at an elevated temperature and then heating them to a temperature below that at which they became softened while allowing them to shrink by at least 50% of the amount by which they will shrink when completely free from restraint. Copolymers containing 52-60% of vinylidene chloride and 40-48% of acrylonitrile are preferably used, spinning solutions containing 18-25% of the copolymer preferably being fed to the spinning jet face at room temperature, i.e. 18 DEG -25 DEG  C.  The coagulant is preferably a 9-20% aqueous solution of acetone at a temperature of 40 DEG -60 DEG  C.  After coagulation, the filaments, in the form of a bundle or yarn are washed with water preferably at a temperature not above 50 DEG  C. while passing round a pair of thread-storage thread-advancing rollers or a thread-storage thread-advancing reel and are then dried preferably at a temperature below 50 DEG  C. after which they may be packaged and given a low degree of twist, e.g. 1-4 turns per inch.  The yarn is then stretched preferably at a stretch ratio of between 3 : 1 and 12 : 1 while softened by hot water or wet steam at 85 DEG -120 DEG  C. or softened by dry heat, preferably at 160 DEG -230 DEG  C. while passing through a slot in a metal block maintained at constant temperature by electric heating.  The yarn is then heated either while allowed to shrink freely, or by at least 50% of the amount by which it would shrink when free from tension either under dry conditions at 115 DEG -160 DEG  C. for 5 minutes to 3 hours or in hot water or wet steam at 90 DEG -130 DEG  C. for 1/2 -2 minutes or for up to 2-3 hours.  The yarns may be cut into staple lengths which may be converted into spun yarns either alone or blended with other fibres, e.g. cotton, regenerated cellulose or cellulose acetate fibres.  Both continuous filament and spun yarn of suitable denier may be used for carpet yarn. Specifications 643,198, 674,323, 709,995 and 720,187 are referred to.

Title: Improvements in or relating to electric storage batteries
IPC: H01M10/12
Filed: 1941-07-04
Abstract: 550,334. Accumulator batteries. VARLEY DRY ACCUMULATORS, Ltd., FULLER, L., and LARK, H. D. July 4, 1941, No. 8442. [Class 53] A method of making a lead-acid accumulator of the " dry type consists of assembling the electrodes whilst still unformed and the separating material within the container and subsequently forming the electrodes by passing a current. Preferably the electrodes are pasted with the usual lead oxide and acid mixture. Owing to the active material being held on to the plates by the filling of separating material used in " dry " accumulator batteries, the acid employed for the forming charge may be of normal strength without causing disintegration of the plates, so avoiding the necessity of replacing it after the forming charge. Preferably the mixtures used for pasting the negative and positive plates are such that they become completely formed simultaneously, a suitable mixture for the negative plates being 75 parts by weight of litharge and 25 parts of red lead and for the positive plates 50 parts each of litharge and red lead, moistened in each case with sulphuric acid of 1.100 specific gravity. Before filling the cell with acid, air trapped in the pores of the electrodes and filling material is drawn off by a vacuum. Single cells may be immersed in acid during the forming charge. The cell shown comprises a cylindrical lead container 10 in an outer insulating casing 19, a layer 11 of negative active material, separating material 13, a layer 15 of positive active material, and a central conductor 14. A porous ceramic disc 17 held by a lead ring 18 burnt to the container maintains the contents under pressure. Specifications 257,019, [Class 53], 432,775, and 506,062 are referred to.

Title: Improvements in or relating to control-units for electric cookers
IPC: H05B1/02
Filed: 1944-05-08
Abstract: 578,709. Control systems for heating resistances. McAULEY, G. May 8, 1944, No. 8645. [Class 38 (iv)] An electromagnetic contactor supplying power to a cooker, may be closed and opened automatically at desired times and is manually controllable at will. The contactor may control at the same time auxiliary circuits, for example for an electric fire or audible alarm device. The time switch shown in the Figure, comprises a motor M, driving at a slow speed, two independently adjustable cams CN and CF, which close and open respectively, in their zero positions, a mercury switch MS. Operation of the "auto" push-button switch, energises a relay A through normally closed contacts of the "on" push-button switch, normally open contacts of the " auto " pushbutton switch and normally closed contacts of the " off push-button switch. The relay locks in over its contact A3 and contacts A1 and A2 operate respectively to light an indicating lamp L1 and start the motor M. Relay contact A4 operates to transfer the energising circuit for the contactor coil C from the " on " push-button switch to the mercury switch MS, which closes and latches in to energise the contactor after an interval determined by the cam CN. The closure of the contactor lights an indicating lamp L2. The latch is released after a further interval determined by the cam CF. Operation of the " off " pushbutton switch at any time, will de-energise the relay and the contactor. Operation of the " on " push-button switch at any time, will de-energise the relay and energise the contactor through normally closed contacts of the "auto" and "off" push-button switches in series, relay contact A4 and normally open contacts of the " on " push-button switch. Closure of the contactor effects a locking circuit for coil C through the contactor blade C3, relay contact A4 and normally closed contacts of the "off" and " auto push-button switches in series. P1 and P2 are sockets for connecting auxiliary apparatus in parallel with the cooker. Audible warning of the operation of the contactor to closed or open positions, may be obtained by connection of a transformer BT through a selector switch ALS as shown, so that the time switch may operate to give alarm clock service.
