Patent DE-3817109-A1 (DE)
Title: Coupling device
Inventor: MUELLER HANS
IPC: B29C45/17
Filed: 1988-05-19
Abstract: In the case of known coupling devices, releasing takes place with the aid of a sickle spanner (hooked wrench), which has to be held by hand, to be precise whenever the coupling returns with the hydraulically operating ejector mechanism. Owing to confined conditions, this action is very laborious, and there is a considerable risk of a working accident. The novel coupling device is intended to permit troublefree use with no risk of any working accident. The coupling device comprises a coupling pin (2), which can be connected to the injection mould and bears grooves (30), and a coupling housing (1), which can be connected to a machine and has a number of profiled jaws (10) for engagement with the coupling pin (2). Each of the jaws has in an opening (9) a sloping face for engagement with a conical face (28) of an annular piston (20), which is mounted movably in an annular space (39) in the coupling housing (39). The piston is sealed off from the space (39) and is actuated by means of pressure medium which acts on the piston depending on the intended action. For safety, a number of helical springs (29) are provided, which hold the jaws (10) in the closed position even if there is a loss in pressure. The coupling device has, furthermore, a connection part (16), which can move slightly for the purpose of centring perpendicularly with respect to the longitudinal axis of the coupling device. <IMAGE>
Patent DE-3818802-A1 (DE)
Inventor: BUETTNER WILLIBALD
IPC: F16N13/04
Filed: 1988-06-03
Abstract: The invention relates to a lubrication pump, having a stroke movement of a supply piston (10) with adjustable proportioning for the quantity of the lubricant supplied by one pump stroke, the supply piston, which is operated by the pump, sucking the lubricant into an induction chamber (12), whose volume can be adjusted, the lubricant furthermore being supplied from this induction chamber, via an intermediate holding chamber (33), to the lubricant outlet or lubricant circuit, and a non-return valve being provided in the aforesaid supply path of the lubricant. In order to feed the supply quantity, which is adjusted with the aid of the positioning arrangement, tolerably accurately, i.e. with only small quantity deviations per supply stroke to the lubricant circuit, it is provided that the non-return valve (20) is arranged, seen in the supply direction (32) of the lubricant, connected to the holding chamber (12) and in front of the intermediate holding chamber (33). This prevents air entering into the intermediate holding chamber and renders the adjusted supply quantity precise.

Patent DE-3830671-A1 (DE)
Inventor: GROEGER RUDOLF
IPC: B24D18/00
Filed: 1988-09-09
Abstract: In a method for manufacturing grinding devices (26) using a mould (1), in which method the grinding compound (24) consists of a binding agent mixed with abrasive grains (27), the profiled surface (18) of the casting chamber (9, 10) has an open structure. Thus the abrasive grains (27) adjacent to the profiled surface (18) assume a random position after the solidifying in the binding agent, their sharp corners and edges preferably being orientated at right angles to the grinding surface. The grinding device (26) is thus immediately ready for use without the uppermost layer first having to be removed by dressing. <IMAGE>

Title: Process for preparing a moist mixture of plaster of Paris and waste-paper fibres
Inventor: BOLD JOERG DIPL PHYS
IPC: C04B18/24
Filed: 1989-02-26
Abstract: In the preparation of a moist mixture of plaster of Paris and waste-paper fibres, the waste (used) paper delivered in bales is first reduced in size to about the size of a postage stamp. In this state, it is moistened up to 200% (percentages are by weight, dry substance = 100%). Only then are the pulping and the mixing with plaster of Paris carried out. The "moist digestion" of the waste-paper fibres has, in comparison with the known dry digestion, advantages in respect of handling and fibre quality.
Patent DE-3906808-A1 (DE)
Title: Security box
Inventor: MATOUSCHEK THOMAS
IPC: G08B13/14
Filed: 1989-03-01
Abstract: The security box is a further development of the conventional pyrotechnic security container ("money bomb"). It is used for transporting cash, cheques and the like. The security box consists of a plastic basepart and a cover part, in both of which electrical conductors are laid and are connected to one another via plug connections. When the box is closed, the plug connections are initially mated, the monitoring electronics are switched on immediately after this, automatically, via a microswitch and the electrical conductors are made live, operated by a battery. A voltage failure caused, for example by breaking the box open or the like, results in a pyrotechnic object being detonated by the monitoring electronics, the gas pressure of which pyrotechnic object sprays a coloured liquid over the contents of the security box so that they are permanently marked. The security box is provided with a combination lock (code lock). The box, which is closed by pressing it to before transportation, can be opened only via an accessory unit, after entering the correct, multi-digit numerical sequence, as a rule at the bank.

Title: Device and method for measuring three-dimensional objects
Inventor: MUEHLBERGER KLAUS
IPC: G01B11/24
Filed: 1989-04-04
Abstract: The invention relates to a method for contactless measurement of the outer contours of three-dimensional objects, having a distance measuring unit which operates by means of electromagnetic rays, measures the distance of an object in the Y-direction along the measuring beam and is moved in the Z-direction. In this method, the object to be measured is rotated about an axis of rotation parallel to the Z-direction, which can be crossed by the measuring beam, and/or the measuring unit is moved in the X-direction. The rotary position of the object and the X-position and Y-position of the measuring unit are known for each individual measurement, so that the relative position of the point measured on the object can be calculated with respect to a reference point using geometrical principles.
