Title: Means for indicating an excess current condition in any of the anodes of a multiple anode ionic valve
IPC: H02M7/08
Filed: 1963-11-21
Abstract: 1,056,458. Protective arrangements. ALLM€NNA SVENSKA ELEKTRISKA A.B. Nov. 21, 1963 [Nov. 29, 1962]. No. 45946/63. Heading H2K. [Also in Division F2] An arrangement for indicating excess current at an anode of a multiple anode ionic valve, e.g. due to unbalanced loading, comprises for each anode a thermal release device 5 energized in proportion with the anode current, and a gas valve 11a ... 11d controlled by the device 5. The valves 11a . . . 11d are connected in an insulating pipe line 14, 20 extending between a gas reservoir 15 and a pressure-operated switch 23. Under normal conditions the valves 11a ... 11d are open so that pressure gas from reservoir 15 acts on the switch and holds it open. In the event of overload at an anode, the associated device 5 releases its valve 11 which shuts off the gas supply from the reservoir 15 and vents the rest of the gas system to atmosphere. The switch 23 closes to cause a signal to be given. The valves 11a ... 11d may be connected in series as shown to control a common switch 23; but reference is made to an alternative arrangement in which the valves 11a ... 11d are connected in parallel and operate independently.

Abstract: 1,059,005. Frequency changing. MULLARD Ltd. Nov. 2, 1965, No. 46325/65. Heading.H2F. A microwave frequency doubler comprises a waveguide arrangement having a first, section A of normal aspect ratio receiving input energy at, say, 9 Gc/s., a second section B of reduced height (Figs. 2 and 3, not shown) and a third section E of normal aspect ratio transmitting energy at 18 Gc/s., the section B containing a diode D. A rectangular metal member I is disposed across, but insulated from, the waveguide at the beginning of the section B. This member, which has a width L1 of # out /4 prevents energy at 18 Gc/s. being transmitted back. The diode D is placed at one of four electric field maxima for 18 Gc/s. in the TE 02  mode D, F, G, H, and is on the axis of the output section E. The septum M provides a short circuit to energy propagating at 9 Gc/s. The waveguide portion C acts as a terminating section for energy in the lower portion of the waveguide so that this energy propagates along the portion E in the TE 01  mode. Input impedance matching probes P are provided. The manner of mounting the diode is disclosed (Fig. 4) not shown.

Abstract: 1330939 Injection moulding KRAUSSMAFFEI AG 7 Oct 1971 [31 Dec 1970] 46724/71 Heading B5A Synthetic plastics material is injected by an injection unit 2 into a mould 3 in a mould closing device 1 by way of a plate 7 containing passages 8 connecting the injection nozzle 2a to the runners 5 of the mould, the plate 7 being removable after the mould is filled to reduce heat exchange with the mould while the plastics material sets. With thermosetting plastics the temperature of the plate 7 is kept below the curing temperature whilst the mould is kept above this temperature. With thermoplastics the mould may be cooled and the plate heated to keep the plastics fluid. In the embodiment shown a plate 7 containing passages 8 is moved by an hydraulic ram 13 to lie between upper mould half 3b and upper platen 10 of hydraulic mould closing and clamping device 1. The nozzle 2a of the injection device 2 is placed against the passageway 9 in plate 7 and plastics material injected through into the mould. After injection the injection unit is lowered, the plate 7 withdrawn, and the platen 10 moved down to contact the mould while the plastics material sets. In a similar embodiment (Fig. 3, not shown), the plate 7 is permanently connected to the end of the injection barrel and the whole assembly is moved to and from the mould. The injection may be mounted to rotate about a vertical axis between a series of moulding stations. In a further embodiment (Figs. 4 and 5, not shown) material is injected into a mould (17) in the direction of mould closing. The plate (20) containing the injection passages is contiguous with a second plate (29) so that when the plate (20) is displaced by an hydraulic ram (30) from the mould, it is replaced by the second plate (29) which may be heated or cooled to keep its temperature close to that of the mould.
