Title: Improvements in elastic multi-ply fabric and process of making the same
IPC: D06B1/10
Filed: 1938-01-28
Abstract: 488,699. Elastic compound fabrics. INTERNATIONAL LATEX PROCESSES, Ltd. Jan. 28, 1938, No. 2756. Convention date, Feb. 12, 1937. Addition to 448,669. [Class 140] An elastic fabric is made by uniting two layers of fabric by a rubber-containing substance in a non-elastic condition, condensing the fabrics, and causing the rubber to assume properties which will enable it to maintain the fabrics permanently united in a condensed condition. Two lengths of woven or knitted fabric 12 and 13 are sprayed with latex by nozzles 14, partly dried by a fan or heated coils 15, brought into proximity between rolls 16, and thereafter united and condensed between elastic belts 18 and 19 which are extended lengthwise between rolls 21 and 20 and allowed gradually to contract with the fabrics interposed under diminishing pressure exerted by belts 27 and 28. The rubber layer is set or vulcanized by heaters 32 and 33. The rubber may be applied to the fabrics as a liquid, plastic, dough, vulcanized or vulcanizable dispersion. A latex - coagulating acid may be applied to the fabrics between the nozzles 14. Belts 18 and 19 are of rubber, woven elastic webbing, or constant-width belts, e.g. as described in Specification 488,694. The sides of the belts 18 and 19 which contact with belts 27 and 28 may be coated with powdered talc.

Title: Solar energy collector
IPC: F24S23/74
Filed: 1977-01-25
Abstract: In a glass jacket tube (40) which is transparent or translucent over its entire circumference and one end of which is closed, a glass absorption tube (41) is inserted, leaving an interspace, the closed end of which is adjacent to that of the jacket tube. At their ends opposite their closed ends, the two tubes are interconnected in a sealed manner by fusing together and a vacuum is created in the intermediate space. On the outer surface of the absorption tube, there is a coating which absorbs solar energy and has an absorption capacity of 0.8 or more and an emissive power of 0.1 or less. A conducting pipe (43) extends through the absorption tube to its closed end in such a manner that a fluid, on flowing back through the annular space between the two tubes, can carry the absorbed energy away. The design makes possible free mutual length changes of the two tubes in operation while avoiding sealing problems; it also makes possible economical manufacture. <IMAGE>

Abstract: <PICT:0944337/C3/1> A heterogeneous abradable material, particularly for the inter-stage sealing of turbines, consists of 2.5-10% by weight of dispersed particles of graphite and/or mica in a matrix of porous aluminium, and may be produced by flame spraying.  A low-porosity bonding layer of heat resistant material such as molybdenum, chromium, nickel, niobium, tantalum or tungsten may first be applied to the surface to be coated, and this may be followed by one or more layers of the ductile matrix metal of graduated porosity. The material may be attached either to the fixed or to the rotating member of the turbine; it may be deposited directly on to the said part, or may be produced separately and subsequently attached thereto mechanically.  As shown in Fig. 3, seal material 12 is attached by key 29 to member 23, a channel 33 being formed by relative motion of member 23 and blade 28.

Title: Method of removing contaminating metals and metalloids from zinc-bearing materials
IPC: C22B1/08
Filed: 1935-01-31
Abstract: In a process for eliminating cadmium and lead from zinc-bearing pre-roasted materials, zinc concentrates &c. by heating with chlorides, such as sodium, calcium, or magnesium chloride, in one working stage, the comminuted dry charge of zinciferous material, chloride, and carbon is mixed with so much water, say 12 per cent, that coherent lumps can be formed by compressing the mixture, and the moistened mixture is immediately charged into a sintering furnace in order to minimize solution of the chloride, and blast sintered at 1050--1500 DEG  C.  A preferred composition of the initial charge mixture is 93 per cent ore carrying 56--72 per cent zinc, 4 per cent carbon, and 3 per cent of sodium chloride.  Before being mixed the ore and chloride are passed through a 200 mesh sieve, and the carbon, preferably coke, through a 10 mesh sieve. Specifications 355,840 and 359,923 are referred to.

Coal dust &c. is briquetted in an eccentric ring-roll press by at least one compressing element movable relative to the ring and the roll so that it can be forced into or against the coal particles while they are held under pressure by the ring and roll to cause angular shear strain of such magnitude and distribution as to produce a strong briquette. In the embodiment of Fig. 1, spring-loaded plungers 6, located in the ring 2, are forced inwardly by roller 4 at the point X and compress the coal dust against roll 1 to form briquettes B. In the embodiment of Fig. 7, two outer disc-like members 111 and a central disc member 1 are eccentrically mounted with respect to each other and to a ring 2 so that maximum compression occurs at the bottom of the press. In other embodiments (not shown) plungers may be located in the roll, or shaped moulding rings may be provided on either side of the ring and the roll. Specification 807,433 is referred to.

Abstract: 138,987. Cable Accessories Co., Reeves, F. H., and Crawford, A. Feb. 12, 1919. Switches, quick-break; covers. - In a quickbreak iron-clad switch of the kind in which the movable contact member and the operating handle-lever are hinged outside the box on the same pivot as the lid, the quick break is produced by a spring operating between the contact-arm and the hinged lid. As shown, the box carries lugs c which receive a hinge-pin d passing through similar lugs on the lid, through the contact-member e which projects through the box, and through the operating-lever h located between the double arms of the contact-member. The contact-member has a projection g between which and the lid the free end of a spring q coiled round the pivot pin acts to produce the quick break. The operating-lever is bent so as to overlie the lid when the switch is closed; opening the lid under these conditions opens the switch. Some lost motion is provided between the operating-lever and the contact-member, the surfaces k, l co-operating for the closing movement and the shoulders j, i for the opening movement.

The pressure surface may be the end of an axial blind bore in the piston into which a tube 12 slidably fits, Fig. 2 (not shown), or loosely fits, with the addition of a plunger slidable therein, Fig. 3 (not shown), for transmitting the pressure to the surface. Spring or fluid pressure from a source 10 acting permanently on piston surface 27 moves the piston leftwards and pressure from 10 supplied through the valve 8 and a line 11  moves the piston rightwards. Non-return valves 25, 26 ensure pressure changes in the signal line only at the stroke ends. The signal line may be fitted with adjustable throttle valves (58, 59) to cause a delay at the stroke ends. A modifier valve may be provided to allow fluid to flow in or out of the signal line and thereby cause the valve 8 to changeover before the full end of stroke piston position is reached.

Title: A reed organ
IPC: G10B1/08
Filed: 1964-01-28
Abstract: 1,043,121. Reed organs. Y. FUKUSHIMA. Jan. 28, 1964, No. 3674/64. Heading GSJ. A reed organ includes a key-operated valve mechanism which varies the volume of sound propagated by the reed chamber according to the speed or violence with which the key is depressed and sustaining means to maintain the valve open after release of the associated key. When the valve 1 is opened there is an inrush of air, due to the partial vacuum in sound box 22, causing the reeds 21 to vibrate and set up pressure waves. The arm 6 carrying the valve can be flicked or gently lifted upwards according to the violence with which the key 10 is depressed so admitting more or less air to the reed chamber 19 and so varying the volume of sound. The valve may be maintained open to thereby sustain a note either by maintaining the key depressed to cause the lip 14 to meet the curved face of the valve and prevent it from falling back, the degree of depression of the key determining the extent of the valve's opening, or by moving the lip 25 under the lip 5 of the valve by the action of the pedal 44 enabling the key to be released. The individual lips 25 carried on the spring-biased beam 24 have a slot 25<1> (Fig. 5, not shown) underneath, enabling their ends to be bent upwards but not downwards so that closed valves may be opened when the sustaining pedal has been operated. A damper pad acts on a metal diaphragm 41.
