Title: Rotation-thrust joint
IPC: H02B11/02
Filed: 1981-03-31
Abstract: The invention relates to a rotation-thrust joint by means of which a heavy and tension-loaded retaining component (such as a retaining plate) can be pushed out of a housing and can subsequently be pivoted, in that a sliding bolt which supports the retaining component is displaceable in at least two bearing blocks which are firmly connected to one another by means of a tube, which sliding bolt is secured in the pushed-out state, against being pushed in inadvertently, by means of a return lock having a locking pawl and a locking element interacting with it. <IMAGE>
Patent DE-3117375-A1 (DE)
Title: Relay circuit
Inventor: NIEFNECKER ALBERT
IPC: H01H47/22
Filed: 1981-05-02
Abstract: A relay circuit for a relay, especially for a current-surge relay, has an RC circuit which is connected in series with the winding of the relay. A changeover element or changer of the relay is connected in series with either one or the other winding of the relay, which is constructed with two windings, and with the RC circuit. Loads (Ll; Lr) can in each case be connected in parallel with the relay winding and RC circuit. When the relay (A) is driven, for example via a key (T1), the RC circuit (R1, C) enables the capacitor (C) of the RC circuit to make it possible for a large current surge to flow through the relevant relay winding and to switch the changeover element (a1) over very quickly. Very high switching speeds can be achieved using this relay circuit. <IMAGE>

Patent DE-3145073-A1 (DE)
Title: Reciprocating piston engine with devices for the formation of fuel aerosols
Inventor: SCHAICH JOSEF
IPC: F02B23/10
Filed: 1981-11-13
Abstract: In the case of known internal combustion engines of this type an air-coal dust mixture is introduced into the cylinder or into an auxiliary chamber connected to the cylinder and ignited by means of the air heated by compression. In these engines solids occur on the oil-wetted cylinder wall before, during and after combustion. Accurate dosing of the coal dust and control of the combustion are not possible in the known engines. In order to permit control of the combustion and to prevent solids coming in contact with the cylinder wall it is advisable to use external ignition and to enclose the mixture in an air ring. A characteristic feature is that on the inlet device (2) a spigot (6) projecting into the compression chamber is provided with at least one fuel nozzle (10) and, essentially during the compression cycle, a fuel-solids-air mixture is blown into the circulating air in such a way that a mixing zone enclosed by solids-free air is produced and the combustion is initiated by means of an external ignition source (12) and a gaseous fuel-air mixture. Reference is made to the attached drawing (Fig. 1). There are possible applications of the invention in internal combustion engines of all types. <IMAGE>

Title: High-speed circuit breaker
Inventor: POHL FRITZ-RICHARD
IPC: H01H77/10
Filed: 1982-03-05
Abstract: The high-speed circuit breaker is provided with an electrodynamic contact system having contact supports (2, 4) which move relative to one another, one of which is supported in a contact holder (6), which is connected via a switching shaft (8) to a latching mechanism, by means of a contact shaft (10), such that it can rotate. According to the invention, the contact support (4) is provided in the region of its contact shaft (10) with two cam discs (12, 14) which are arranged eccentrically and are opposite one another and parallel, and whose ends facing the switching shaft (8) are in each case provided with a cam section. By means of this measure, it is intended that the contact spring force which is detrimental to high-speed automatic contact opening should no longer counteract the opening movement of the contact support (4) after a short opening movement and, if required, that a force component supporting the opening movement of the contact support (4) should come into effect. <IMAGE>

Abstract: The invention relates to a hollow plastics profile as a spacer profile for multi-pane insulating glass. The hollow profile is disposed in the edge region of the insulating glass unit between two glass panes. Moisture which may be present in the pane interspace or which may penetrate into this is bound by desiccant contained in the spacer profile. This is effected by the advantageous design of the spacer profile, which consists in the wall directed towards the pane interspace consisting of vapour-permeable plastic and the other sides enclosing the hollow space of the spacer profile being provided with a vapour barrier.
Patent DE-3307445-A1 (DE)
Title: Process for the friction welding of parts
Inventor: ALT CLAUS-CHRISTIAN
IPC: B23K20/12
Filed: 1983-03-03
Abstract: The invention relates to a process for the friction welding of parts, in which the two parts to be welded are rotated relative to one another during a heating phase under slight mutual pressure; after sufficient friction heating of the parts, their relative rotation is braked, and the parts, which are stationary relative to one another, are pressed together with high axial force. In order to shorten the braking time, it is proposed to rotatably mount both parts and to apply the requisite braking or acceleration work to both parts to be welded, which braking or acceleration work is necessary to bring about the relative stoppage of both parts. This can be done by the part stopped first in the heating phase being accelerated in the braking phase in the direction of rotation of the rotating part. According to another proposal along the same lines, the two parts are driven in opposite directions of rotation during the heating phase and are then braked approximately at the same time and equally rapidly. Owing to the two proposals which can be used alternatively, a shorter braking time can be achieved, as a result of which materials with a low melting point and high thermal conductivity, such as, for example, aluminium, can also be welded without glazing of the weld structure in the peripheral direction. Such glazing would impair the strength of the welded joint.
