Abstract: 920,764. Cutting-out presses. F. SCHROTER. June 2, 1959 [June 2, 1958], No. 18825/59. Class 31(1). [Also in Group XVI] In a cutting-out and embossing press in which sheet or web material S is fed to the operating stations of the press by means of two intermittently fed spaced endless conveyer belts 1, the longitudinal side edges of the material are attached to the conveyer belts by impaling them on shouldered needles 11 carried by the belts. The belts pass over rotatable guide discs 2 provided with pins 3 to engage holes 4 in the belts. The discs 2 are adjustable transversely of the machine by means of rotatable spindles 8 provided at their ends with screw threads of opposite hand. The discs are driven intermittently from a drive shaft 24 by means of gearing 25 to 28 and an oscillatory gear crank 29 which engages a pinion 32 mounted about a freewheel on a shaft 6 carrying the discs whereby movement of the crank in one direction is transmitted to the shaft 6 while movement of the crank in the opposite direction is made ineffective by the freewheel. The machine has a feed table at station A comprising two shafts 12, 13 carrying a number of transversely-movable longitudinal rods 14. The sheets are aligned against a member 15 by first raising the feed table by pivoting the shaft 13 about the shaft 12.

Title: Betatron-started synchrotrons
IPC: H05H11/04
Filed: 1949-07-18
Abstract: 661,247. Magnetic induction accelerators. AKT.-GES. BROWN, BOVERI & CIE. July 18, 1949 [July 28, 1948], No. 18830/49. Class 39 (i). In a betatron-started synchrotron accelerator, separate supply sources are used for the excitation of the magnetic guiding field and of the magnetic accelerating field in the central core. An auxiliary winding in series with the excitation winding for the guiding field compensates the flux induced by it in the central core. For exciting the accelerating flux in the central core, a current of higher frequency is used than that for exciting the guiding flux. The excitation of the accelerating flux becomes effective when the guiding flux passes through zero. The transition from betatron to synchrotron operation does not involve saturation of the central core. In one embodiment, Fig. 1, the winding 9 for the accelerating flux surrounds one limb of an iron core 8<SP>1</SP>, magnetically separate from the iron core 1 for the guiding flux. The compensating winding 10 has the same number of turns as the winding 4 for the guiding flux. In another embodiment, Fig. 3, a single iron core 1 is provided, and the current pulses for producing the accelerating flux are injected into the compensating winding 10. The winding 10 has less turns than the winding 4 for the guiding flux, but may have an equal number, if an air gap is provided in the central core, or if the winding 10 is shunted by a resistance 21. These current pulses are supplied through an auto-transformer 16 and thyratrons 17, 17<SP>1</SP> which are ignited periodically when the guiding flux passes through zero under the control of a current transformer 20. The wave form of the current pulses may be varied by means of the resistance 22.

Title: Improvements in or relating to the casting of metals
IPC: B22D27/13
Filed: 1956-06-18
Abstract: 796,980. Casting-processes. LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT. June 18, 1956 [June 16, 1955], No. 18840/56. Class 83 (1). Gas-pressure is produced in a dead-head or heads by one or more gases formed by the interaction of at least two inorganic-substances contained in said dead-head or heads, which react with one another as a result of at least one of said substances melting at the temperatures developed in the dead-head or heads during casting. CO 2  gas may be produced by a mixture of an alkali metal-carbonate and silicon-dioxide, e.g. quartz or boron-trioxide or an alkali metal-bichromate. When casting magnesium, the gas produced is sulphurdioxide which may be evolved from an alkali metal-bisulphite and an alkali metal-bichromate. Slag-forming constituents, e.g. calcium-oxide or fluoride may be added. The gas-generating substances are preferably in powder form and may be contained in perforated metal, perforated or porous ceramiccasing, or in a calcined asbestos-casing 10 in tablet form, e.g. as tablets 11, Fig. 2, compressed from a mixture of two parts by weight of SiO 2  powder and one part of sodium-carbonate powder, or as a tablet 13, Fig. 3, of sodiumcarbonate and a tablet 14 of quartz powder. Hollow spaces in the casing, e.g. as in Fig. 3, are preferably filled with asbestos-wool. The generation of gases is thereby delayed so that an impervious metal-skin may form on the wall of the dead-head 4, a process which is expedited by the metal-caps 6, 6<SP>1</SP>. In a modification, gas-generation is further delayed by placing one of the substances in a metal dish so that the substances do not interact until said dish melts.

[Also in Division B8] An apparatus for dispensing a measured quantity of gaseous liquid, such as beer, comprises a liquid measuring vessel 30 connected to inlet and outlet valves A, C and a gas expansion chamber 32 having a valve 42 for admitting liquid therein and communicating with the vessel via ports 52, 53, the arrangement being such that when the liquid has filled the vessel and has reached a level in the chamber determined by the balance of the liquid and gas pressures, the supply of liquid to the vessel and chamber is cut off and the discharge valve is opened whereupon the gas under pressure passes by way of the ports 52, 53 to effect discharge of a measured quantity of the liquid from the measuring vessel through the outlet valve C. The inlet and outlet valves A, C and the valve 42 are actuated by means of cams 24, 25, 48 mounted on a shaft 20 which is rotated via a handle 81; the inlet and outlet valves each have a resilient washer 12, Fig. 3 (not shown), and the cams act on the ends of the valves via a cup 14. The valve 42 is provided with an extension 49 slidable in a guide 51 having bores 53, 70, the bore 53 being normally closed by a spring-loaded needle valve 60, Fig. 5 (not shown). The valve 60 is opened by a diaphragm 62. In operation, with the inlet valve A and valve 42 open as shown in Fig. 1, beer under pressure is fed into the vessel 30 and rises into the expansion chamber 32 until the gas pressure therein balances the pressure of the beer. The cam-shaft is then rotated to close the inlet valve and valve 42 and open the outlet valve C. The pressurized gas in the expansion chamber 32 then flows through port 70, past the needle valve 60 and then through port 52 to thereby assist in the dispensing of the beer from the measuring chamber; a pair of identical measuring chambers and associated valves are mounted side by side so that as one chamber is filling the other is dispensing. Additional pressurized gas may be fed via a manifold located in the base 1 of the apparatus in order to accelerate the dispensing operation.
