Abstract: 387,060. Muffle furnaces. SMALLWOOD, A. and FALLON, J., British Mills, Cornwall Road, Smethwick, Birmingham. Nov. 10, 1931, No. 31100. [Classes 51 (i) and 51 (ii).] A muffle furnace is heated by a series of refractory tubular combustion chambers disposed transversely around and within the working chamber e and each making a complete interior circuit thereof. As shown, the combustion chambers are of rectangular form, each one being built up of lower, upper, and side tubes a .. d, connected by socket joints g which are so arranged that they are maintained gastight by gravity. Adjacent combustion chambers are traversed by the heating gases in opposite directions, the burners f, which each deliver into one of the lower tubular members a, being arranged in staggered formation along the opposite side walls of the furnace. The waste gases escape through outlets h to a pair of offtake flues i, j in which may be disposed means for heating air for secondary combustion. This heated air is delivered from side flues k, l to opposite ends of the lower members a of adjacent combustion chambers through ports m. Each combustion chamber may communicate with one of the waste gas flues i, j so that recirculation of the gases may take place.

Title: Apparatus for the electrolytic deposition of metals
IPC: C25D17/24
Filed: 1930-12-29
Abstract: 362,191. Electroplating. SOC. ANON. WALDBERG, 223, Boulevard Pereire, Paris. Dec. 29, 1930, No. 39100. Convention date, Dec. 27, 1929. [Class 41.] Barrel apparatus.-An inclined rotatable vat for plating small articles is provided beneath its base with magnets for holding the articles in firm contact therewith, the magnetic action being periodically varied to allow mixing of the articles. When permanent magnets are employed the variation is effected by movement of the poles or by deflection of the flux by a movable yoke piece ; when electromagnets are employed, the field current is periodically interrupted. In the apparatus shown the vat b is mounted on a shaft d carrying a worm wheel d<1> driven by a worm d<2>. The shaft carries a pinion g<1> driving a pinion g which engages a contact supplying current to the electromagnet e and is provided with an insulating segment for interrupting the current. An electrode h for insertion in the vat is mounted on a carriage k sliding on a rail l and is counterbalanced by a weight m. After plating has proceeded for some time with the electrode h connected as anode the circuit of the electromagnet e is broken and that of an electromagnet i on the electrode h is made so that the articles are attracted to the electrode h ; the electrolizing current is simultaneously reversed so that plating proceeds on parts of the articles previously covered. On completion, the electrolizing current is broken and the part h is raised carrying the articles with it. At the uppermost position, a contact n on the carriage k leaves the contact rail o, riding on to an insulating strip p so as to break the circuit of the electromagnet i whereupon the articles are dropped into a shoot r adapted to be placed beneath the electrode h. The electrode h is provided with a lead liner j and the vat b with a brass plate c to prevent the effects of residual magnetism. As an alternative to provision of the shoot r the electrode h may be pivoted to allow the goods to fall free of the vat. A flange u provided with a spout v is mounted above the vat to receive overflow of electrolyte. Cool electrolyte may be supplied to the vat by a pump. Specification 341,093 is referred to.

Title: Method of applying a mirror to a plastics box

Abstract: 1446073 Coating with pre-formed sheets ELI LILLY & CO 21 Aug 1973 [12 Sept 1972] 39605/73 Heading B6G A mirror-like reflective surface is applied to a plastics box by placing a foil strip having a light reflective foil on a backing over a predetermined area of the plastics box, applying a die under simultaneous pressure and heat on the backing, the application of said pressure commencing on a limited area of said foil strip and progressing on said foil strip only toward the perimeter of the predetermined area to force air to escape beyond said area's perimeter as the die completes its compressive action over the predetermined area, thereby effecting a stamped-outer portion of the foil on the foil strip to become affixed in a smooth relationship with the box. As shown in Fig. 4 a die 16 having heating means 17 is used to stamp a foil strip having a suitable foil 19 on a polyethylene terephthalate backing 20 on to the lid 14 of a box. Die 16 has a stamping surface 21 which is of a convex configuration as shown in Fig. 3. The centre of the die is therefore the first point to make contact with the foil strip and then upon further downward movement of the die this pressure progressively advances toward the perimeter of the predetermined area into which the foil is to be affixed so that all air that would otherwise be trapped between the foil and the box is forced to the outside. The elimination of air results in a flat reflective area of foil which has no discoloration, wrinkles or other imperfections that would reduce the reflective properties of the foil.

Title: Cooling substances or generating power by use of liquefied  gas

Filed: 1972-08-25
Abstract: 1378555 Gas turbine plant K IMAI 25 Aug 1972 39686/72 Headings F1G and F1Q [Also in Divisions F3 and F4] In apparatus for cooling a fluid medium, substance or the engine of a ship or vehicle or for utilizing the heat of such medium as a source of energy for the generation of power, a liquefied gas e.g. Na, CO, CO 2 , O 2 , CH 4 , or air is used as working medium in a cycle wherein the liquefied gas is heated, expanded adiabatically and reliquefied. The liquefied gas is disposed below its critical temperature and pressure in a closed container 1 and heated by means of a heat exchange system 3 ... 7 to its critical temperature whilst its pressure is regulated to a specific value above its critical point by a high pressure tank and valves 10, 10'. Thereafter the gas is heated in a heat exchanger 17 which directly or indirectly in a heat exchanger 22 removes the heat from the medium, substance or engine to be cooled. The heated gas passes to a turbine or piston engine 16 for adiabatic expansion wherein the released energy is converted into another energy form to reduce the gas temperature to below its critical temperature, which gas thereby or thereafter is liquefied to pass to a reservoir tank 37 for controlled return to the container 1. At least a portion of the power generated by the turbine or the like is used to effect the flow of the liquefied and gaseous working medium in the system. Liquefaction of the gas may occur solely by temperature drop occurring during the adiabatic expansion or, as shown in Fig. 2 (not shown), may occur by compression to its critical pressure and cooled by heat exchange with the gas immediately after expansion. The fluid medium to be cooled or the source of heat may be ambient atmosphere or sea water.
