Title: Improved driving device for a machine for casting stereotype plates and the like
IPC: B41D3/00
Filed: 1932-06-06
Abstract: 384,913. Printing-surfaces. SCH€FLEIN, K., 2, Kornhausstrasse, and MASCHINENFABRIK WINKLER, FALLERT, & CO. AKT.-GES., 35, Wylerring- strasse, both in Berne, Switzerland. June 6, 1932, No. 15939. [Class 100 (ii).] In a machine for casting stereotypes or for backing electrotypes, the opening and closing of the mould and of the valve controlling the flow of metal from the melting - pot are effected by means of one or more pistons, actuated by fluid pressure, the flow of fluid to ensure the periods of rest and motion being controlled by a slowly-rotating part. The three-cylinder pump is driven by a motor 1 which also drives a shaft 24 slowly through worm gearing 25 .. 28, the shaft carrying cams 20 .. 23 acting on valves 16 .. 19 controlling the flow of pressurefluid through pipes 12 .. 15 leading to cylinders 29, 30. The cylinders are provided with outlets at each end controlled by valves 32, 33 and 34, 35 respectively, acted on by cams 36 .. 39 on a shaft 40 driven from the shaft 24, the outlets communicating with a pipe 31 draining into the storage tank 5. In use, the cam 21 first opens the valve 17 and allows fluid to be forced through the pipe 14 to the lower end of the cylinder 30 to raise the piston and through the connections 46 .. 50 closing the mould. The valve 18 is then opened by the cam 22, and the fluid, flowing through the pipe 18, raises the piston in the cylinder 29 and through the parts 52, 53 opens the cock 51 in the melting-pot. A cam 45 on the shaft 24 then opens all the valves leading from the tank 5 to the pump so that no more fluid is forced into the cylinders 29, 30. By altering the length of the raised portion of the cam 45, the time for cooling can be regulated. When the plate is cool, the cam 45 releases the valves controlling the flow from the tank, the cam 23 opens the valve 19 to permit the flow of fluid to the top of the cylinder 29, and the cam 39 opens the valve 33 to cause the piston to descend and close the cock 51. The valve 16 is then opened by the cam 20 to permit the fluid to pass to the upper end of the cylinder 30 and the valve 35 is opened by the cam 38, the resulting movement of the piston opening the mould. A cam 43 on the shaft 24 then disconnects the clutch 44 and stops the pump and shaft 24. The speed of the shaft 24 can be adjusted by changing the worm gearing 25 .. 28, and if desired, the shaft 24 can be driven by a separate motor. In a modification, the piston-rods of the cylinders 29, 30 can be provided with racks gearing at the correct times with gear-wheels on a shaft which carries cams controlling the opening of the inlet valves to the cylinders. In a further modification, a single pressure cylinder is employed, the piston-rod being connected to a toothed segment which controls directly the opening of the cock and is in gear with a wheel driving the mould, the segment passing out of gear with the wheel before the cock is opened, and re-engaging with it when the cock is closed.

Title: Process for the manufacture of yeast-containing baking powders
IPC: A21D8/04
Filed: 1925-06-22
Abstract: 236,210. Pollak, A. June 24, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Baking-powders.-A yeast-containing baking- powder is made by intimately mixing the usual constituents of baking-powder with yeast which has been liquefied, the yeast or the mixture being dried at a low temperature. The liquefaction may be effected by the aid of sacchariferous bodies such as dry sugar, concentrated syrups or malt extract, or by the use of organic acids, such as lactic acid, preferably in conjunction with sacchariferous substances. To expedite the drying process, to render the mass less hygroscopic, and to increase the enzymatic content of the baking-powder, substances such as amylaceous bodies, albumen, fat, starch flour, ordinary flour, casein, dried milk, malt extract or powder, phosphates or other salts, diastase of fungi or the like, &c. are preferably added to the liquefied mass prior to drying.

Abstract: 313,161. Vereinigte Eisenbahn- Signalwerke Ges. June 8, 1928, [Convention date]. Friction apparatus on permanent way.- Relates to brakes for railway vehicles of the kind comprising shoes or jaws mounted on the track and adapted to grip the wheels of passing vehicles and consists in arrangements whereby the wheel as it enters between the brake shoes tends by its rotation to release the brake, and as it it leaves the shoes tends to increase the grip, thereby preventing the tendency of the wheels to leave the rails. As shown in Fig. 1, the brake comprises a shoe 3 connected by a lever 10 to the piston rod 5 of a compressed air cylinder 4 and a second shoe 2 pivoted at 7 to the cylinder 4 and held normally in raised position against a stop 8 by a spring 9. The wheel 1 as it enters between the shoes depresses the shoe 2 against the action of the spring 9, thus reducing the braking pressure, and as it leaves tends to lift it again to increase the grip. The arrangement shown in Fig. 2 comprises a roller 11 bearing against the wheel 1 and also against a roller 14 disposed in a wedge-shaped recess 13. The entering part of the wheel 1 rotates the roller 11 in the direction of the arrow, thus causing the roller 14 to move upwardly in the recess 13 and so relieving the pressure on the wheel, while the leaving part of the wheel acts to force the roller into the recess and increase the pressure. In a further construction, a roller such as' 11 is spring mounted for vertical and slight lateral movement, and bears directly against a fixed inclined surface down and up which it is respectively forced to travel by the entering and leaving parts of the wheel.

Title: Improvements in aerials for use in wireless signalling
IPC: H01Q21/12
Filed: 1923-06-21
Abstract: 226,246. Franklin, C. S. June 21, 1923. Directive signalling; aerials.-Directive aerials are constructed from a number of vertical wires or rods spaced apart a fraction of a wavelength and connected together at the top and bottom by horizontal wires. Each vertical part together with the wires connecting it to the next is tuned to the wavelength to be used. The system is fed at equidistant points with currents in the same phase by means which do not affect the tuning and then radiates two beams at right-angles to its plane in opposite directions. Two or more such systems may be arranged one above the other, as shown in Fig. 1. The systems are coupled by small condensers k or by the capacity of the horizontal wires d, e. Oscillations in the horizontal wires are prevented bv breaking them at intervals or by inserting resistances r. To provide for uni-directional working a similar system, spaced an odd multiple of #/4 behind the first, is provided, to act as a reflector, and according to the, Provisional Specification may be fed with current. The reflector may be much higher than the radiator and may be in the form of a cylindrical parabola with its focal line horizontal and coincident with the aerial. Examples of practical dimensions and the effect of varying them are given in the Specification. A method of feeding the aerial at a number of points to ensure that the parts are in the same phase is shown in Fig. 2. The electrical distance of each transformer a .. d from the source must be the same, and the transformer ratios are arranged to prevent reflection at the feeding points. The cables may be built up of parallel tubes or rods like a Lecher wire svstem and enclosed in metal conduits. The transformer may be inserted between the ends of the vertical parts or between the wires d, e. In the case where the resistance of the portion being fed is nearly equal to the critical resistance necessary at the cable terminals to prevent reflection, transformers need not be used. Specification 128,665 is referred to.
