Title: Improvements in and relating to the spreading of plastic substances on cakes, wafers, and other foodstuffs
IPC: A21C15/00
Filed: 1928-05-03
Abstract: 321,403. Vicars, Ltd., T. & T., and Crosland, E. M. May 3, 1928. Rolling-machines.-Relates to apparatus for sheeting plastic confectionery material, and more particularly for spreading jam, cream, or the like, on to wafer, cakes, or other foodstuffs. The material 1 is taken from a hopper 2 by a pair of rolls 3, 4, which form with a roll 5, substantially touching the roll 4, a chamber 13 in which the material is compressed either because the space between the rolls 3, 4 exceeds the space between the rolls 3, 5 or because the peripheral speed of one or both of the rolls 3, 4 exceeds that of the roll 5. A scraper 6, having a short concave face ending in a sharp-edged recess, which ensures that the material will leave the scraper, is arranged to remove the sheet from the roller and deposit it on a wafer 14 on the conveyer 15. A scraper .7, having a sharp edge on each side to break the contact with the substance, is pivotally mounted to engage either with the roller 3, as shown in Fig. 3, or with the roller 5, in which case the material returns with the roller 3 to the hopper. The rollers 3, 4 may be roughened or grooved to grip the material, and the roller 3 is journaled in a frame pivoted about the axis of the roll 4 so that the space between the rolls 3, 5 is variable by screws 44. The rolls 3, 4 are geared together and the rolls 4, 5 are driven by worms on a vertical shaft carrying a friction disc 36 which is slidable thereon to vary the speed of the rolls. The friction disc 35 is slidable on the driving pulley shaft and is moved into contact with the disc 36, to start the machine, by means operated by the handle 46, rod 39 and crank 56. The conveyer 15 is trained over a drum driven by worm gearing 19, 20 and variable-speed friction discs 16, 17. The shaft of the roller 18 carries cams, one of which actuates the extension 39a of the rod 39 to stop the machine, and the other raises an adjustable swinging fence 27 which retains the wafer until it is correctly positioned on the conveyer 15, and then rises to allow it to pass. The lever 25 of the scraper 7 is oscillated by a cam plate 23 which is reciprocated by a cam on the shaft of the roller 18. The duration of the dwell of the scraper 7 on the rollers 3, 5, and consequently the length of the cream sheet deposited on the goods, is regulable. In operation, the attendant pushes the handle 46 and starts the machine, the roller 18 revolves once, the scraper 7 and rolls 3, 4, 5 apply a coating to one wafer and the machine is automatically stopped. The machine is restarted for another cycle of operations by pushing the handle 46. The rollers may be heated electrically or otherwise. Specification 321,414 is referred to.

Abstract: 627,135. Heating and cooling liquids in bulk. CALOMAX (ENGINEERS), Ltd., and PEARSON, G. May 15, 1947, No. 13058. [Class 64(iii)] A self-feeding water heater and boiler is provided with a heating chamber from which boiling water is delivered into a receiver having an open tapless delivery nozzle. Further, the lower part 2 of a cylindrical body 1 forms a water-heating chamber and a receiver 6 having an open top is disposed within the heating chamber above the normal water level, the base 13 of the receiver being inclined towards the open delivery nozzle 15. A steam heating coil 4 is arranged in the heating chamber and surrounds a centrally disposed displacement tube 3. When the steam valve (not shown) is opened, steam is admitted to the coil and heats the water in the heating chamber to boiling point and the expansion and turbulence of the boiling water causes it to pass up the passage 17 and into the receiver 6 from whence it passes to the delivery point the displaced water being automatically replaced from a float controlled supply tank 5. Deflectors 8 and 10 prevent condensate formed on the upper part of the body 1 from flowing into the receiver and holes 9 in the deflector 8 direct the condensate back to the heating chamber. The deflector 8 also serves to assist in directing the boiling water into the receiver 6. The cylindrical body 1 is surrounded by glass silk insulation.

Title: Metallurgy of tin
IPC: C25C1/14
Filed: 1926-05-27
Abstract: 254,284. Guggenheim, D., Guggenheim, M., Guggenheim, S., R., Guggenheim, S., Macgowan, J. K., and Smith, E. A. C., (trading as Guggenheim Bros.), (Assignees of Smith, E. A. C.). June 27, 1925, [Convention date]. Tin and ferric chloride, obtaining. - Ores, concentrates, and other materials containing tin in the metallic state are leached with a mixed solvent containing 25 gms of acid per litre; the resulting solution is electrolyzed. Slight variations in the composition of the leaching solvent may be made according to the material to be treated. The material should be granular and not sintered. The acid is preferably hydrochloric or sulphuric. When sulphuric acid is used an appropriate chloride is preferably also added. The resulting electrolyte contains stannous and ferrous chlorides. It is electrolyzed in cells without diaphragms with cathodes of tin or other metal and anodes of graphite or other non-corrodible material. The flow of electrolyte is regulated so as to regenerate a solvent of t:he original constitution. The ferrous chloride acting as a depolarizer enables the voltage to be reduced from 3.0 to 1.4. The acid content should be sufficient to prevent hydrolysis of the iron and tin chlorides. A small amount of glue or other colloid may be added to improve the character of the deposit, but is omitted when there is sufficient silicic acid obtained from the ore or concentrate. The residue from the first leaching, containing tin sulphide, may be dissolved by leaching with a solvent containing ferric chloride. A suitable solvent may be obtained by electrolyzing the solvent previously described in a diaphragm cell or by passing chlorine gas into it. The solution is electrolyzed for deposition of tin in a diaphragm cell resistant to acid corrosion. Before entering the cell it is diluted by the addition of liquid from the anode compartments until the concentration of tin is reduced to 25 gms per litre. The spent catholyte is passed through the anode compartments to regenerate the leaching solvent. A colloid agent may be added to improve the cathode deposit. Bismuth and antimony are left behind in the first leaching, provided all the tin is not dissolved, but are dissolved in the ferric leaching solvent. When the concentration has become sufficiently high they are removed by cementation on tin. Any excess of iron salts in the solvent is removed from time to time by crystallization or otherwise. Small losses of acid are made up from time to time.

Abstract: 788,645. Temperature-responsive actuating-elements. ROBERTSHAW-FULTON CONTROLS CO. May 2, 1956 [Aug. 5, 1955], No. 13562/56. Class 64(2) A temperature-responsive apparatus comprises an expansible and contractible member 10 having a part 18 arranged for movement upon expansion or contraction of the member, a temperature sensitive bulb 14, and a tube 12 connecting the bulb and the member in a closed system filled with fluid, the bulb having at least one portion formed of materials having different co-efficients of thermal expansion so that its volume is unaffected when all of its wall has undergone a temperature change. The bulb may be formed from a sheet of bimetallic material with the high expansion side forming the exterior surface and have a recess 26 filled with a flexible insulating substance 32. Upon an increase in temperature, the chamber 23 within the bulb contracts due to flexing of the legs 30, 30 of the uninsulated portion so that fluid is injected into the member 10 to provide an instant response in anticipattion of the fluid expansion, the legs 30, 30 being restored to their original positions after the increased temperature has reached and expanded the portion 26. A fall in temperature produces a temporary increase in the volume of the chamber 23. The substance 32 may be removed to provide a chamber of constant volume for all temperatures. The element 10 may consist of a pair of corrugated discs connected to a support by a threaded stud 16 and arranged to operate a valve or switch. The bulb 14 is welded or soldered to the tube 12 and has an end 22 which is flattened or crimped after the system has been charged with fluid under pressure.
