Title: Rail mounting pushbutton locking terminal block - has conductor clamped between forked sprung prongs of button with insulation cutting knife edge and accepting different wire sizes
Inventor: HOHORST WOLFGANG DIPL ING
IPC: H01R9/26
Filed: 1980-09-11
Abstract: The terminal joins or connects together conducting wires irrespective of whether they are insulated or of the wire diameter. It consists of a conducting rail (15) fixed in an insulating body (13) with at least one locking spring (16) which is mounted in the body and holds the one locking spring (16) which is mounted in the body and holds the wire electrically and mechanically in contact with the rail. The spring takes the form of a push-button (26) which slides into the body and locks in the engaged position like a fork with the conductor held in the U-shaped gap between the prongs and the ends of the prongs (20) in contact with the rail. The connector is located by a guiding channel at either side of the spring. The insides of the prongs have symmetrically stepped sharpened edges which remove insulation and make contact with the conductors of different section. The prongs may be guided by their outer edges between elastic jaws in the conducting rail, and are curved to increase the locking force as the button is pushed further. The knife edged ends of the prongs cut the insulation, the insides clean the oxide layer of the wire by friction, and then make sharp edged contact as the button is locked in place. The connector is mountable on a supporting rail (14) and the push-button may be lockable in three positions to take account of three conductor sizes.

Patent DE-3039619-A1 (DE)
Inventor: GASSER HANS-H
IPC: E04C3/14
Filed: 1980-10-21
Abstract: Upper and lower flanges (3, 4) of the girder consist of solid wood and are connected to the web (6) by means of wedge-type finger jointing (11). The web (6) has to absorb essentially transverse forces and is therefore subjected principally to shear forces. Intersection of the stress trajectories in the central axis at 45 DEG takes place in webs which are subjected purely to compression. The shear strength of the webs is improved in that the wood-grain directions of each of the layers (7, 8, 9) of the webs do not run parallel and perpendicular to the longitudinal axis of the girder, but at 45 DEG . A possible variant is the arrangement of the central layer (9) at 45 DEG  and of the two outer layers (7, 8) perpendicularly to the girder axis. A third variant, which is, however, not equivalent in terms of statics, consists in the central layer (9) being inclined by 45 DEG  with respect to the longitudinal axis, while the two outer layers (7, 8) are arranged parallel to the longitudinal axis. In any case, even the advantage in terms of statics of this third variant is considerable with respect to the conventional web layers which are glued perpendicularly to one another. The wooden girder is simple and inexpensive to construct, and therefore to produce. It has a greater bending strength and flexural rigidity than the known wooden girders. <IMAGE>

Title: Detecting coal mine rock fall danger - involves face coal movement and convergence of seam floor and roof measuring
Inventor: SCHAEPERMEIER EGBERT DR
IPC: E21F17/00
Filed: 1980-11-18
Abstract: The detection of possible rock fall danger in a coal mine uses measurement of relative displacement of coal (2) at the face w.r.t. adjacent rock, and of convergence near the face (1), i.e. approach of seam roof (3) to seam floor (4). The quotient of the displacement divided by the convergence in the same vertical cut is determined. Risk of rock fall is derived, and only when such risk is apparent, standard test drillings are made, to establish the risk. Torsion of roof in relation to floor may also be taken into account.

Title: Coin-operated gambling machine for games of skill
Inventor: GAUSELMANN PAUL
IPC: G07F17/38
Filed: 1981-02-07
Abstract: In this machine, in which a number of shots can be fired at targets, symbol-designated by alphanumeric elements, with a slingshot device during a game, is provided with display elements visibly allocated to the targets by means of the symbols, which form a hit field and indicate the hits achieved during the current game. If a predetermined occupancy pattern is achieved on the hit field, an interrogating and weighting device generates bonus signals. The gambler can change the symbol designation of the targets, an influenceable symbol allocating device differently activating the alphanumeric elements of the targets and the display elements of the hit field. This makes it possible to place the targets to be hit for a preferred occupancy pattern so that they can be hit more easily.

Title: Plant for the production of foundry moulds
Inventor: GEISSLER HORST
IPC: B22C15/30
Filed: 1981-02-26
Abstract: The plant is employed in foundries in which castings are produced by means of horizontally split sand moulds. The aim of the invention is to provide a plant for the production of foundry moulds which allows a high degree of flexibility and a high production rate and, with a small requirement for machinery and control instrumentation, takes up a small area. The object of the invention is to achieve any length of core insertion time and the possibility of performing operations on the upper part of the mould and the production without any great modification to the machinery of boxed or boxless sand moulds. This object is achieved by virtue of the fact that the plant has a moulding-material compaction station for the alternate production of upper and lower parts of the mould and a two-part conveying track for lower and upper mould frames, the first part passing through the moulding-material compaction station and the second part moving in the opposite direction, parallel to and at a distance from the first part, and both parts being connected by three transfer (changeover) devices. Arranged on the second part of the conveying track is a lowering and insertion station corresponding to a casting-mould conveyor, this station being replaced, when boxless moulds are being produced, by a knock-out station. <IMAGE>

Patent DE-3118969-A1 (DE)
Title: Process and device for producing the angular guide channel for the pliant element of a corner deflection means of locking rod arrangements on windows, doors or the like
IPC: B21D53/74
Filed: 1981-05-13
Abstract: In this process and this device for producing the angular guide channel, having a cross-sectional profile of a C, for the pliant element of a corner deflection means, an elongate C-profile piece with U-shaped longitudinal edges is bent in an L-shape in its longitudinal direction and produces, in the L-apex, a bend in the guide channel. The pliant element to be introduced in the guide channel is used for coupling longitudinally movable driving rods of two locking rod arrangements which are fitted in the right angle of a window leaf or door leaf. In order that satisfactory guide actions are obtained even if space saving, sharp bends are produced and an inexpensive material is used, the U-longitudinal edges of the profile piece are to be supported, during bending, in the direction of the clear U-height in the profile interior, in the region of the L-apex to be formed, as a result of which an inexpensive bending process is obtained.
Patent DE-3119333-A1 (DE)
Title: Metering device for lubricant
Inventor: KEMNER AXEL ING GRAD
IPC: B61K3/02
Filed: 1981-05-15
Abstract: The invention relates to a metering device for lubricant, in particular for lubricating the wheel flange of rail vehicles. Two chambers for receiving lubricant, the volume of which can be varied by means of pistons, are provided in a housing. The chambers are connected to one another via a common passage serving as a lubricant inlet. The chambers can be connected to a lubricant reservoir via a slide valve arranged in the passage. The outlets of the two chambers are closed by means of respective non-return valves which can be opened in the direction of the outlet. The slide valve and the two pistons are actuated by means of a common actuating element. When the actuating element performs a working stroke, the slide valve is moved into the closed position before the pistons are displaced to bring about a reduction in the volume of the chambers. The positive pressure which arises in the chambers opens the associated non-return valves and applies the lubricant under pressure, via corresponding conduits and nozzles, to the wheel flanges. During the subsequent return stroke of the actuating means, the slide valve is first of all moved into the open position. The negative pressure caused by the subsequent stroke of the piston to bring about an enlargement of the volumes of the chambers draws lubricant into the chambers.

Title: Process and device for producing V-belts open at the flank
Inventor: BRAND WILHELM
IPC: B29D29/10
Filed: 1981-07-16
Abstract: The invention relates to a process and a device to enable the production of V-belts which are open at the flank and trapezoidal in cross-section, for example for motor vehicles. V-belts open at the flank are cut out of an already vulcanised coil which is tubular in structure; hitherto this was done on rigid or expandable cutting drums. Expandable or rigid drums therefore had to be held in stock for each V-belt length. According to the present invention, the vulcanised coil is tensioned over two rolls arranged so as to be adjustable axially parallel to one another and is cut to form individual V-belts, it being possible for the rolls to be held either horizontally or else vertically. The cutting operation is carried out by means of circular knives rotating at high speed.

Title: Vibrating machine for screening and/or conveying, in particular single-mass vibrating machine
Inventor: DUETZ FRIEDRICH
IPC: B01D29/03
Filed: 1981-10-02
Abstract: Vibrating machines for screening and/or conveying are very limited with regard to the design of their working surface and in particular with respect to their width. The excitation of vibrating machines provided with side pieces is also associated with a relatively high expenditure of energy. These disadvantages are eliminated according to the invention in that the working surface is divided up into at least two working surface segments which are located next to one another and/or one behind the other in the flowing or conveying direction of the material and are capable of vibrating independently of one another, and in that each working surface segment has a bearing which is capable of vibration and a driveable vibration exciter. <IMAGE>
