Title: Gas discharge display with selective discharge point excitation - uses opposite cell faces of electron highly reflecting material
Inventor: BYRUM JUN BERNARD WILLIAM
IPC: H01J17/49
Filed: 1974-06-06
Abstract: The multiple gas discharge display panel has a gas chamber filled with ionisable gas and formed by two opposite dielectric charge stores. Behind each dielectric component are mounted electrodes in such alignment as to form a number of individual discharge cells. The discharge point (12) of a selected gas discharge cell is controllably arranged on each of the opposite dielectric charge storage surface (10, 11), via opposite surfaces (1) of material of high electron reflectivity. Each surface on or near a cell discharge point is surrounded by material with low electron radiation (2). The surfaces with high electron reflectivity are preferably formed by spot surfaces of such material, provided in pairs on opposite dielectric charge storage surfaces.

Abstract: The purpose is to improve protection for personnel in the building in the event of explosion, while providing simplification of the structure, in an electric transformer or similar station with medium voltage switchgear where there might be a risk of explosion, in a single-cell building, which may be of the transportable type, with walls of concrete, sheet metal or plastics etc., and where the switchgear extends along a wall, close to it, with pressure release openings provided above this. The space (5) above the switchgear (3) is partitioned off by bulkheads (14) from the rest of the interior (6). The partition consists pref. of reinforced asbestos cement panels, running vertically between the switchgear and the roof (7). The openings are pref. provided only in the part of the building partitioned off, above the switchgear.

Title: Powder-coated contact melt-adhesive granules - have an integral melt coating surrounded by a layer of powder
Inventor: STOCK HEINZ
IPC: B29B9/16
Filed: 1974-07-23
Abstract: Powder-coated granules of a contact melt-adhesive feature an integral coating of a powder material (sic) obtd. from liq. melt-adhesive droplets, and a layer of powder surrounding same. Hitherto, such adhesives had to be stored in siliconised containers. It was not possible to granulate then like other melt-adhesives, and store and ship them in drums or bags. With this invention, the contact adhesive granules are prevented from sticking together by virtue of the powder coating.

Title: Connection monitor for teleprinter exchanges - has timing capacitor discharged by incoming signal and actuating relay operation
Inventor: BLAUERT HANSS DIPL-ING
IPC: H04L12/02
Filed: 1974-08-09
Abstract: The connection monitor for teleprinter exchanges has a discharge circuit consisting of a first transistor (T1), a first resistor (R1) and a first diode (G1) to discharge the timing capacitor (C1) charged from the voltage supply (MTB,-Ub). This capacitor is charged via a charging circuit consisting of a second transistor (T2), a second resistor (R2) and a second diode (G2). The first transistor is turned on, the signal being monitored is received, and the second transistor is biassed off. When the capacitor voltage reaches a given level, the transistors (T3, T5) in the evaluator and amplifier stages are driven into conduction and cause a relay (R) to operate.

Filed: 1974-08-17
Abstract: The cutter has a blade (2) formed by a bar pivotal about a longitudinal axis and cooperating with a stationary blade so that a web (1) passed between the blades is severed when the pivotal blade is turned by means of an electromagnet. The cutting edge of the pivotal blade has a length such that a part (1c) of the width of the web remains uncut and the receipts (1b) remain partly connected together unless a further electromagnet is energised to withdraw a stop limiting the stroke of the first magnet to bring a further edge portion of the pivotal blade into operation and effect complete severance of the web.
Patent DE-2448550-A1 (DE)
Title: Electromagnetically operated shears - for cutting vine-stocks, fruit -trees and other wood-bearing growth, have their power transmitted by means of bowden wire
Inventor: ROTH HERBERT ING GRAD
IPC: A01G3/00
Filed: 1974-10-11
Abstract: The operator of the shears carries a small, light frame on his back, containing the electromagnet and the accumulator necessary for supplying the current. The power is transmitted from the electromagnet to the shears by means of Bowden wire. The electromagnet is switched on and off by means of push button in the handles of the shears. The shears are highly efficient because they do not depend on the muscular force of the user, and use a low current consumption, since only a short period of impulse is needed for each cutting operation.

Patent DE-2460018-A1 (DE)
Title: Sockets with radial grooves formed on plastic pipes - using heated mandrel-outer mould with sprung pressing rollers
Inventor: RIEGEL KARL-HEINZ
IPC: B29C57/08
Filed: 1974-12-19
Abstract: Sockets with radial peripheral grooves are formed on plastic pipes by (a) pushing the heated pipe end over a guide mandrel, (b) applying a first radially acting, variable pressing force on the unheated pipe zone, to fix the pipe onto the mandrel, this being combined with the closing of an outer mould around the periphery of the heated pipe end, (c) pushing the heated pipe end in the axial direction, and (d) applying a shaping force by the outer mould, this being effected during or after (c). Step (c) is effected in two separate, successive axial pushes within the mould cavity. The first push is converted into a radial holding/consolidating force that acts in a centering manner on the inner peripheral region of the heated tube end, before the grooves are formed, and strongly presses this region onto the wall of the outer mould. The second push effects an additional reinforcement of the pipe wall cross-section over the remaining socket/groove region.

Title: Two or three dimensional copy milling machine - ensures independent of inter-dependent transmission of stylus movements to milling head
Inventor: MORENO Y CACHO D JOSE MARIA
IPC: B23Q35/10
Filed: 1974-12-30
Abstract: The two or three dimensional copy milling machine has means for transmitting dimensions on different scale independently in each coordinate direction and these reductions or magnification in relation to stylus movements on master pattern are transmitted to the workpiece. This arrangement ensures that the shape, for example of a shoe making mould, can be readily modified. The moving elements or slides moving in three different coordinate directions can move independently and each of those can be connected by a given lever system to the milling head. The slides can also be connected to each other by mechanical lever system for generating certain relative movements and for modifying the stylus movement transmission to the milling cutter.

Inventor: HERPEL HANS-WALTER
IPC: E01F13/08
Filed: 1975-03-26
Abstract: The barrier post is designed to prevent vehicles from entering forest tracks, which must nevertheless be accessible to prams and wheelchairs, as wells as to walkers. It comprises a bottom part for ground anchorage, and a hinged top part foldable from a vertical barrier position into a clear-way horizontal postion, being lockable in the former. It is fitted with a flush axially displaceable bolt (5), thrust when locked into a setting where it rigidly connects the top and bottom parts (1, 3) of the post. With the top part (3), the bolt is locked by means of a fixing media (7, 8) fitted at a set distance from the ground (2), in connection with the locking mechanism (10). When the latter is released, the bolt is moved into a hinge-(4)-releasing position, to enable the top part to fold downwards. The bolt may be mounted inside the post (5). This is easily manipulated, but cannot be operated by people without authority, and is protected from dirt, rust and snow.
