Title: Improvements in or relating to roller mills
IPC: B29B7/56
Filed: 1932-03-16
Abstract: 382,862. Roller mills. SIMON AKT.- GES., Nossen, Saxony, Germany. March 16, 1932, No. 7858. Convention date, March 16, 1931. [Classes 59 and 86.] In rolling mills for mixing and disintegrating plastic masses, more particularly soaps, toothed strippers a are disposed between each two successive passes of rollers b .. g so that stripshaped shavings are detached and conveyed away over the stripper, whilst the strips passing through the teeth remain adhering to the roller, each roller of which rotates more rapidly than the one preceding it. The strippers may be parallel or inclined to the roller axis and in the latter case may be arched so as to retard and displace the material into the previous pass as shown or may strip the material off the roll before it reaches the pass so that the stripped material is mixed and carried through the pass with the material adhering to the roll.

Title: Improvements in the transmission of motor vehicles
IPC: F16D41/20
Filed: 1929-03-12
Abstract: 327,549. Stancliffe, C. W. March 12, 1929. Locking by frictional detents.-In an automobile, a free-wheel coil clutch of the expanding or contracting type is provided between the gear box and the cardan shaft. A sprag to prevent undesired reverse movement of the vehicle may also be provided and in the preferred form the device is combined with the gear box as shown in the figure. A driving shaft 2 projects through the end-wall 1 of the gear box and has splined to it a drum 5, held in position by nuts 10. The inner surface of the drum forms one element of the free-wheel clutch, spring coils 14 of which are tapered as shown and are attached at the outer end 14a to a collar 13 splined to the driven shaft 11. The end of the driven shaft is chambered to receive the end of the driving shaft with the interposition of a flanged, phosphor-bronze bearing sleeve 12. Splined to the driven shaft and retained in position by a nut 20 is a member 15, having clutch teeth to co-operate with teeth on a slidable dog member 30 splined to the drum 5 and operated externally to give a positive, bidirectional drive when required. A pinion 19 provides a speedometer drive. A member 22 which forms one element of the sprag device is mounted on the drum 5 with the interposition of a bearing sleeve 21, and has secured to it the outer end of the coil spring 23, which co-operates with a fixed drum 24 bolted to the gear box casing. In order that the sprag may be put out of action when required, the member 22 is provided with clutch teeth 25 to engage teeth on the dog member 30 and so put it into, or out of, driving connection with the driving shaft 2. The dog 30 is adapted to be set in three positions to give a bi-directional drive, a neutral position in which free-wheeling is permitted, and a connection to the sprag. The casing 32 may, if desired, be integral with the gear-box casing. Specification 318,474, [Class 80 (ii), Gearing, Variablespeed, &c.], is referred to.

Filed: 1941-06-27
Abstract: 548,574. Hats. ASHWORTH, W. A. June 27, 1941. No. 8096. [Class 63] In a machine for stretching felt and other hat hoods, of the kind wherein the hood is gripped near the edge of the brim by a rim of clips while pressure is applied to the crown, the hood being kept moist by steam or hot water, the clips grip the hat after the commencement of the stretching, each clip gripping the brim as the edge thereof is about to be withdrawn from the clip.

IPC: B65H20/08
Filed: 1925-03-26
Abstract: 234,060. Spiess, G. May 17, 1924, [Convention date]. Feeding webs.-In web-feeding apparatus for cutting or other machines, in which the feed rollers or other devices draw the web continuously from a supply roll and also move bodily so as to arrest temporarily the part of the web being acted upon by the cuting &c. device, the bodily movement of the feed device is effected substantially at right-angles to the direction of feed of the web. In one form, Fig. 5, a pair of feed-rollers 1 are mounted on a slide 9 which is reciprocated by a cam 24 and lever 41 in a path substantially perpendicular to the web 3. The upper roller 1 is driven by a belt 6 passing round a pulley 8 on the slide 9, pulleys 7, and a driving-pulley on a uniformly driven shaft 5, whereby the rollers 1 are rotated continuously at a varying speed, the speed decreasing as the slide 9 descends and increasing as it ascends. A countershaft 14 driven by a belt 13 from the shaft 5 drives, through gearing 15, 16, 17, a shaft 18 which carries the cam 24 and also a cam 19 operating the cutter 23. In a second form, Fig. 6, the feed-rollers 1 are carried by a pivoted arm 28 connected by a link to a second pivoted arm 29 carrying the belt pulley 8 and oscillated in a vertical plane by a cam 24. Specification 205,576 is referred to.

Title: Semiconductor comprising silicon and method of making it
IPC: H01L21/18
Filed: 1956-03-16
Abstract: <PICT:0803830/III/1> A method of making crystals of silicon having two distinct crystalline formations with a transformation junction therebetween comprises maintaining a molten mass of silicon in an atmosphere free of carbon or carbon compounds placing a monocrystalline silicon seed in contact with the mass and pulling the seed to form a mono-crystalline growth on it, and then introducing into the atmosphere at a desired transformation point a gaseous carbon compound so that the material crystallizing thereafter is multicrystalline in structure.  The container 11 (Fig. 1), which may be, e.g. of quartz, alumina, titania or beryllia is heated by a molybdenum heater 13 in a furnace 12 of carbon free alumina protected by molybdenum baffles 15.  A current of helium, neon, nitrogen, or a non-carbonaceous reducing gas such as hydrogen is flowed through the chamber over the molten silicon.  The pure monocrystalline seed 20, which is rotated at 100 revolutions per minute, is air water-cooled so as to maintain a temperature gradient between it and the melt.  As the crystal grows, crucible 11 is lowered by the hydraulic ram 28. The growth may be watched through observation tube 25 and controlled amounts of activator impurities such as boron added to the melt if desired, via tube 19.  After a predetermined time a controlled amount of carbon monoxide is introduced into the inert gas circulating through the chamber so as to cause the silicon crystallizing thereafter to be multicrystalline.

Abstract: 1,042,284. Linkwork. STANDARD TELEPHONES & CABLES Ltd. Feb. 28, 1964, No. 8375/64. Heading F2K. [Also in Division H4] In an electromechanical vibratory device, a driving member and a driven member are connected by a resilient intermediate member which is in frictional contact with either the driven or driving member, the value of limiting friction being such that the intermediate member will slip under a force which would otherwise displace either or both of the driving member and driven member from their equilibrium position by more than a predetermined amount. A telephone receiver (Fig. 1) includes a rocking armature 13 provided with a lug 16 which is gripped by a U-shaped wire spring 19 which passes through apertures 18 in a diaphragm 17 and is secured thereto by " Araldite " (Registered Trade Mark). The value of the pressure of spring 19 upon lug 16 sets an upper limit to the force which can be transmitted between the diaphragm 17 and armature 13. Only one arm of the spring 19 may be resilient. Lug 16 may be notched for location of the wire 19 (Fig. 4, not shown) and the notches may be enlarged beyond the exact size to fit the spring 19. Alternatively, the U-shaped spring 19 may bear on the inside of a slot or hole in the armature lug 16 (Fig. 5, not shown). The closed end of the U-spring may be located with the closed end of the U rigidly secured to the armature lug 16, the arms then being in frictional contact with the diaphragm 17 within the two holes 18 (Fig. 6, not shown). Alternatively the spring 19 may be J-shaped (Fig. 7, not shown). Strip may replace wire for the spring 19. Alternatively, a multi-pronged resilient member may have frictional contact at more than two points.
