Patent DE-2430453-A1 (DE)
Title: Explosion-proof capacitor with cut-out - has housing consisting of two containers snapping together via recess and ridge on walls
Inventor: SCHILLING RAINER KARL DIPL ING
IPC: H01G2/14
Filed: 1974-06-25
Abstract: The explosion-proof capacitor has a cut-out device that operates when a given pressure is reached inside the capacitor housing. The housing consists of two sealed containers that slide together, as in 2430437. The two containers have recesses and corresponding ridges on their opposing walls to form a snap-on connection. The outer container is of plastics and is shrunk onto the inner container. The snap-on arrangement ensures that the two containers are not held together by the cut-out device alone and also that they maintain the required relative position.

Title: Retaining member for coal pick shaft and bore coupling - shaft retained in bore by spring urged insert
Inventor: DENMAN DENNIS
IPC: F16B2/16
Filed: 1974-11-26
Abstract: The shaft of the coal pick is inserted into a bore formed in a box for retaining the pick in an automatic coal mining machine. The bore is of rectangular cross section to prevent rotation of the pick head and axial movement of the shaft is prevented by means of a cylindrical rod bearing on the shaft and located in an inclined slot in the box wall. The rod is urged against the shaft by a rubber cushion disposed in the slot. The pick is inserted by pushing it into the bore but is prevented from dropping out by a self servo action generated by cooperation between rod, inclination of slot and rubber cushion. In alternatives rod is replaced by a ball bearing or other inserts.

Title: Ribbed steel rod for concrete reinforcing grids - where cold formed rod is subjected to alternate bending to restore ductility
Inventor: STRIEPENS HEINZ
IPC: B21D3/05
Filed: 1974-11-27
Abstract: Process for mfg. cold-formed ribbed steel rod for concrete reinforcing grids, where a cold-rolled ro cold-drawn wire or rod is subjected to one or more forming operations to obtain a uniformly distributed rib profile on its surface. forming the ribs and attaining te final dimensions, the rod undergoes a rapid sequence of alternating bending operations to raise its elongation value which drops during rib-formation and also to reduce the yield point and tensile strength of the rod. During the alternating bending operations at least the outer portions of the rod are pred. stressed beyond the elastic limit into the plastic range, and the pref. plant includes relaxation- and straightening rolls. The process is an inexpensive method of restoring the elongation to the required min. of 8% afer rib-formation without the use of heat treatment.

Title: Railway safety signalling system - has two way transmission between control centre and train
Inventor: GELLERMANN WOLF DIETER DIPL IN
IPC: B61L3/22
Filed: 1975-01-15
Abstract: The system uses track-side receivers and transmitters placed at intervals along the rails to identify train positions. The control centre circuit comprises a counter and register which holds a location signal corresponding to each train position along the track. A clock pulse generator provides a continuous strobe for counters and registers. Interrogation signals also synchronised by the same timing pulses are sent to line via a send/receive terminal and received and decoded by the locomotive via the track pick-up devices. By means of the continuous comparison of incoming and outgoing pulses, train movement can be indicated and controlled. The arrangement can also provide an indication of train speed.

Title: Pneumatic tyre with beadings clamped in one groove - has two pairs of contact surfaces between beadings
Inventor: TANGORRA GIORGIO
IPC: B60C15/02
Filed: 1975-04-04
Abstract: A wheel and pneumatic tyre for an automobile comprises a tyre with a non-stretch reinforced tread and with two lateral walls, the centre lines of which, as viewed in cross-section, are convex inwards so that the walls are predominantly loaded in compression and bending; the two beadings of the side walls are both seated in a common channel at the wheel rim, which has undercut edges, the width of the open mouth of the channel being less than the maximum internal width of the channel, and the total width of the beadings being such that they are compressed together when in the channel; this arrangement is improved by the beadings having mating axial surfaces at their radially inner edges which are closer together, when the beadings are not compressed, than a second pair of mating surfaces, which are radially further outwards. By bringing the two halves of the rim, together, the beadings become compressed and the surfaces are brought into contact. In a variant, there is a separating element, e.g. an inverted U-section, i.e. a channel section open radially inwards, situated between the mating faces of the two beadings. This intermediate section m ay be of a highly thermally conducting material. The anchorage of the tyre beadings in the wheel rim is still further improved.

Title: Portable radiation dose meter - using small ionization chamber which discharges electrostatic plates
Inventor: BAUSER HERBERT DIPL PHYS DR
IPC: G01T1/14
Filed: 1975-08-04
Abstract: The simple portable radiation dose meter of a few centimetres diameter depends on the amount of charge removed from two charged plates across an ionization chamber. The dose meter can be used either as a routine radiation dose monitor or as a danger warning depending on its construction. It has the advantages associated with ionization chamber radiation measurement, combined with small size. The meter consists of a small disc shaped chamber (1, 6) containing two charged plates (4', 4") separated by a spacing ring (5) and clamped in place by another ring (2). Between the plates is a gas filled chamber (12) and the radiation dose received is measured by the field strength remaining between the plates after exposure to radiation.

Title: Plastics thread wound silo core - has coil heads generating horizontal and vertical relative movements in winding
Inventor: BRUEMMER HEINZ
IPC: E04G21/12
Filed: 1976-03-26
Abstract: In the process for silo construction, a previously assembled silo core has a plastic-saturated thread, emerging from one or more coil heads, wound round it, with a vertical relative motion between core and coil head superimposed on a continuous horizontal motion. The silo core is mounted in a fixed position, each relative movement being generated by a movement of the coil heads. For this a circular working platform (3) with one or more coil heads, can be rotatably fastened relative to a circular stage (2) suspended on a support structure (1) and movable up and down. The vertical movement can be effected by cables wound up and unwound on a single cable drum, and the support structure may comprise towers (4) symmetrically mounted round it and connected at their top ends. Difficult transport of wound silo cores onto site is eliminated, and diameters in excess of 4m can be produced without difficulty.

Title: Air pressure loss warning system for vehicle tyre - has valve dust cap formed as contact switch which closes warning device actuating circuit
Inventor: TRUPP ANDREAS
IPC: B60C23/04
Filed: 1977-02-04
Abstract: The air inflation valve dust cap is formed as a contact switch which responds to air pressure loss by completing an electrical circuit. The circuit then actuates an audible or visual warning device in the drivers cab. Current is passed from the air valve dependent switch to the warning device by means of fixed and rotating capacitor plates. The one plate is fixed to the chassis exactly opposite to the second plate which rotates with the wheel. The two plates form a capacitor whose capacity continually alters. For twin rear tyres, parallel leads from the respective air valve caps lead to the second plate.
