Title: Improvements in and relating to rolling mills
IPC: B21B13/00
Filed: 1935-06-04
Abstract: 436,783. Rolling wire rods. SCHLOEMANN AKT.-GES., 13, Steinstrasse, Diisseldorf, Germany. June 4, 1935, No. 16264. Convention date, June 4, 1934. [Class 83 (iv)] A number of wire rods b are passed in parallel through the roughing stands 11 to 16 of a rolling mill and thereafter each rod is led to individual roll stands, e.g. 17 and 20 bridged by a guide 23 for the last two finishing passes, the guides 23 crossing each other. This eliminates the irregularity when finishing all the wires in a mill with a number of grooves where one pass adjustment could not compensate for the different wear of the individual grooves. There may be more roughing stands to compensate for the fewer finishing passes. A single wire a may be passed through all the stands as shown.

Title: Plant for the treatment of vegetable and animal raw materials with an extraction or lixiviation liquid
IPC: C11B1/10
Filed: 1930-05-27
Abstract: An apparatus for treating vegetable or animal raw materials with an extraction or lixiviation liquid consists of two extractors or two sets of extractors, connected together at their bases by a conduit through which the extraction liquid passes, said conduit having a heating device inserted therein.  Two sets of extractors 1, 2, Fig. 1, are connected together by pipes 3, 4, and to a pump 12, <PICT:0358536/III/1> <PICT:0358536/III/2> a heater 13 through which low-pressure steam passes, and a centrifuge 14.  A pressure cylinder 15 is connected at the remote ends of the pipes 3, 4 and to a multiway cock 11, whereby a difference in pressure between the pipes 3, 4 moves the piston which reverses the cock 11.  In operation, the vessels 1, 2 are filled with the material to be treated, e.g. whale blubber and a suitable extraction liquid is added.  A pump 12 draws the extraction liquid from the vessels 2 through the pipe 4, heater 13 and centrifuge 14 to the vessels 1 through the pipe 3.  When the pressure in the vessels 1 reaches a predetermined limit the piston moves to the right whereby the intake of the pump 12 is connected to the pipe 3 and the liquid returns through the heater &c. to the vessels 2.  In the centrifuge 14 air and extracted oil are separated from the extraction liquid; the liberated air passing through a purifier 20 wherein vapours are condensed, and the separated liquids passing to separators 16, 17.  A minimum level of liquid is maintained in the separators by a pressure regulator 23.  The apparatus may be employed in the digestion of wood pulp or in a leaching process.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also an apparatus suitable for domestic washing.  The clothes are placed in vessels 1, 2, Fig. 2 (Cancelled), which are connected at their bases by a double-walled tube 3 heated, for example, by an electrical resistance, and are connected by a tube 9 at the top.  The vessels are mounted on a pivotal support 31. In operation one vessel is filled with the extraction liquid, and the apparatus is tilted at intervals, the liquid being heated during passage between the vessels.  This subject-matter does not appear in the Specification as accepted.

Patent GB-476649-A (GB)
Title: Improvements in the manufacture of films, foils, coatings and the like
IPC: B29C48/08
Filed: 1936-06-12
Abstract: Fancy films, foils, and the like are formed on a surface by evaporation of a volatile solvent from a solution of a film-forming base in said solvent, and during evaporation, numerous small bubbles are caused to form in said solution with the aid of a powder adapted to provide nuclei for said bubbles and previously applied to said surface.  The film-forming base may comprise cellulose esters or ethers, or natural or artificial resins.  The powder and the film-forming solution may be applied to a surface travelling along a closed path through a heated atmosphere.  In a modification, the powder is applied to, and the solution is extruded on to, an at least partially dried layer of said solution supported on an endless band and applied <PICT:0476649/IV/1> <PICT:0476649/IV/2> during a previous revolution of the band.  Suitable powders are cellulose derivatives, natural and synthetic resins, organic substances of high melting point, dyestuffs, pigments, and metal powders, and a number of these are specified.  It is preferable that the powder should be compatible with the film-forming base. The powder 9 contained in the hopper 8 is measured out by means of the perforated rotating disc 13, and allowed to fall into the duct 30 through which flows a stream of air from the fan 29.  The mouth of the duct opens on to the endless band 32 to which is subsequently applied the film-forming solution.  The fan 29 and the measuring disc 13 are connected by suitable gearing 24, 26 and 27.  In examples, ground cellulose acetate, which may be plasticized with diethyl phthalate, is distributed on to a surface to which is subsequently applied a solution of cellulose acetate in acetone.  The temperature at which drying takes place may be from 30 to 60 DEG  C., according to the bubble size desired. Specifications 396,424 and 396,723 are referred to.

Abstract: 168,452. Kawakami, S. June 18, 1920. Tappet gears; fluid-actuated gears. - A duplex-acting pump, driven by steam or water power, is provided with a mechanical or fluid-actuated valve-gear, the action of which is independent of the length of the pump stroke. The gear operating the valve of an adjacent cylinder becomes operative at the piston midstroke position and completes the valve movement during a short portion of the stroke. The piston completes its stroke and half of the return stroke before the valve is again operated. Each piston pauses at the end of each stroke until its valve is operated. In the mechanical gear shown in Figs. 4, 5, 12, and 15, the piston-rods 4, 4' are provided with oscillating tappets c, d, c', d<1> the arms of which alternately engage arms a, b, a', b<1> secured in pairs to arms 14, 14' which carry short levers 13, 13<1> connected to the valves 5<1>, 5 of the adjacent cylinders B, A. In the fluid-actuated gear shown in Figs. 19, 23, and 25, the valves 5, 5<1> of the cylinders A, B are worked by auxiliary pistons 23, 24, 23', 24<1> which work in cylinders 25, 26, 25<1>, 26<1> communicating at their outer ends by pipes 27', 28', 27, 28 with auxiliary distributing-valve chests 18', 18, Figs. 29 and 30, which have passages 22<1>, 22, 19', 19 communicating respectively with the exhaust passages by ports 9<1>, 9 and with the main cylinders by central ports 16'. 16. The plug valves 18, 18' are connected by links and levers 15, 15<1>, 12, 13, 12', 13<1> with the piston-rods of the auxiliary pistons. When the piston in cylinder A passes the port 16, fluid is supplied to one of the pistons 23<1>, 24<1> to move the distributing-valve 5<1> and the auxiliary valve 18' into position to effect the reversal of the valve 5 when the piston in the cylinder 13 passes the port 16<1>. A modification is described wherein auxiliary slide valves are used.

In a coin- or token-operated subscriptiontelevision system a transmitter transmits simultaneously to receivers debit signals related to the price of a programme and the price is compared at each receiver with the amount of credit outstanding so as to actuate an acceptance mechanism allowing reproduction of the programme and to debit the cost to the credit means, only if the credit exceeds the price, the debit signals being transmitted alternately with debit-cancelling signals restoring the credit to its initial value if the programme is not accepted. Should a programme be accepted but not broadcast in its entirety credit signals are sent out restoring the credit balance to its initial or any other value as determined at the transmitter. At the end of the programme, signals preventing further reproduction are transmitted preferably modulated on a control carrier wave together with the debit, debitcancelling and credit signals. The system may also include an audience measurement unit. Reference has been directed by the Comptroller to Specification 928,855.

In the form shown in Fig. 2, a fan 12 supplies air to the gas or oil burner 10 and to the combustion chamber, and forces the combustion gases through the pipes. Alternatively, the fan may be at the pipe outlet, or at an intermediate position. In the stove shown in Fig. 3, solid fuel is burnt in a combustion chamber 25 surrounded by a lagged air jacket 24. A fan 26 supplies air to the jacket and a valve controls the flow of air through a pipe 30 into the combustion chamber. A filter or cyclone separator may be provided in the piping near the stove. A cooking and water-heating stove may be used to supply the combustion gases and a boosting stove may be provided between the main stove and outlet.
