Title: Improvements in machines for forming wafer cornets
IPC: A21B5/02
Filed: 1929-01-31
Abstract: 325,974. Winzer, H. C. Jan. 31, 1929. Making wafer biscuits. - Wafer cornets are formed from flat square blanks which are laid with their diagonals over the hinge of a pair of half-moulds, the blank being wrapped around a conical core, which is laid thereon, by the closing of the half-moulds. As shown the cores 17 are carried on stems 19 which are pivoted on brackets carried on an endless chain 7. The stems 19 have rollers 20, at their free ends, which run in a track 21 and normally maintain the cores projecting radially from the chain 7. A section 22 of the track 21 is carried by toothed segments 24 which are oscillated by sectors 26 operated through links by a cam 30. The blanks are removed singly from a magazine 39 by a reciprocating pusher 38 and laid on the half moulds 40, the bottom wafer in the magazine having been moistened, to facilitate bending, by a stem or water spray. The guide section 22 then swings the core 17 into a substantially horizontal position on to the blank, and the half moulds 40 are closed around the core by levers &c. operated by a cam 42. The edges of the blank are joined by a bar 61 which passes through a gap between the free ends of the hinged half moulds and presses the edges together. The bar 61 is slidable in a frame carried by a cranked bar 60 extending between extensions 23 of the segments 24 so that the bar follows the core as it is swung over on to the wafer blank. The bar is normally kept away from the core by springs, but when the halfmoulds have wrapped the wafer blank around the core, the bar is pressed on to the edges by fingers 83 which are actuated by a cam 41 and levers 52, 54, 56. The bar 61 may be fitted with a detachable stamp to impress a name on the joint. The conveyer chain 7 is moved intermittently by a Maltese-cross gear 8, and, when the comet has been formed, conveys them through a drying-chamber 62 having heaters or supplied with hot air. The cornets are removed from the cores 17 by roller brushes 66, 67 between which the cores stop. The cornets fall on to a discharge conveyer 69. The cornets. being formed of square blanks, each have a projecting lip.

Title: Improvements relating to weighing machines or balances
IPC: G01G3/04
Filed: 1925-02-06
Abstract: 246,671. Salter & Co., Ltd., G., and Hughes, J. B. Feb. 6, 1925. Indicating mechanism; spring balances.-In a weighing-machine or balance the connecting mechanism between the pointer-operating-mechanism and the platform or load-carrying member comprises at least three relatively movable members resiliently interconnected by one or more tension or compression springs which determine the maximum force capable of being imparted to the pointer-operating mechanism in either direction, a pair of the relatively movable members being also positively interconnected so that one moves the other with it in a downward direction, and another pair of the relatively movable members being similarly connected so that one moves the other with it in an upward direction. As applies to a platform weighing-machine, Fig. 1, wherein the draw-rod 2 is attached to an H-shaped member 11 supported by weighing-springs 9, the H-shaped member carries a T-shaped slide 15 which in turn carries an inverted T-shaped slide 17. Springs 13 tend to hold the head of the slide 15 against the top of its guides 16, and springs 25 draw the two T-shaped slides together until the slide 17 abuts against the bottom of a rib 22 on the inner slide 15. A rack 18 attached to the outer slide 17 actuates the spindle 20 of the indicating pointer. If a load is suddenly placed on the platform the sudden descent of the H-shaped member leaves behind the slides 15, 17 until these are caused to follow-up by the action of the springs 13, at the same time actuating the indicating pointer. Upon the sudden removal of the load the H-shaped member carries up the slide 15 but the slide 17 is left behind until restored to contact with the rib 22 by the spring 25 at the same time returning the pointer to zero. In a modification, when the load is placed on the platform the central slide is carried down by the rear slide, and the front slide together with the indicating rack follows under spring action. Upon the removal of the load the central slide is left behind and follows under spring action taking the front slide with it. In a further modification, Fig. 10, applied to a spring balance, the load-supporting member 28 carries a cylinder 29 containing a spring through which a rod attached to the indicating rack 18 is actuated. Sudden upward or downward movements of the member 28 cause a compression of the spring to cushion its effect upon the indicat. ing rack. In a further modification, Fig. 12, the indicating rack 18 is actuated through two compression springs 44, 47 contained in a cylinder divided by a central partition 40.

Abstract: 174,955. Akt.-Ges. Brown, Boveri, et Cie. Feb. 5, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Vapours, utilizing for effecting further evaporation; rectifiers; water, distilling; hydrocarbons, distilling.-In evaporating or distilling liquids, the vapours generated in a still a, Fig. 2, are passed through a heat-exchanger f in which they generate vapours from an auxiliary liquid, and these vapours are utilized to effect further evaporation in the still a by being circulated through a compressor d and a coil e in the still. The vapours from the still a may be compressed before passage through the heat exchanger, when compression of the vapours in the auxiliary circuit may be dispensed with. The heat-exchanger may be arranged in the upper part of the still. The vapours from two or more stills may be utilized in separate heat-exchangers to generate auxiliary vapours which are compressed in the same compressor and utilized to heat all the stills. The compressor may be a multi-stage centrifugal compressor, the vapours being admitted at different stages according to their pressures. In evaporating water under reduced pressure, carbon bisulphide or sulphurous acid may be used as auxiliary liquids. The vapour of the auxiliary liquid may be injected into the liquid undergoing evaporation; for example, in distilling oils, the oil vapours may be used to generate steam which is compressed and injected into the oil. Vapours containing two or more constituents may be fractionally condensed by passage from a still a, Fig. 7, through two or more heat-exchangers f<1>, f<2> in succession, the auxiliary vapours from which are compressed in different stages of a compressor d, and utilized separately in heating-coils e<1>, e<2>.
