Patent DE-3116216-A1 (DE)
Title: Apparatus for accurate positioning of an element
Inventor: KITTELL DAVID H
IPC: G03F7/20
Filed: 1981-04-23
Abstract: A method and an apparatus are proposed for aligning the pattern of an opaque mask with a previously exposed pattern on a silicon slice or a silicon wafer. Three separate optical channels are so aligned that their axes coincide with three targets on the slice. The objectives are also aligned at the same vertical distance from the slice. The optical channels then remain stationary. The slice is withdrawn a short distance and replaced by the mask, which also has three targets. The mask is then displaced in order to align the targets with the previously aligned optical axes. Once the alignment of the mask is complete, the mask and the slice are removed as a unit and taken to an exposure station.

Title: Process and moulding for the sterilisation of plastic pourers
Inventor: HEINLEIN HANS
IPC: B65B55/06
Filed: 1981-05-14
Abstract: Plastic pourers, which can be inserted into the mouth orifice of bottle-like containers closable by means of a cap, often have to be sterilised, particularly also together with the corresponding containers. So that the dimensional stability especially of the parts of the pourers essential for the sealing effect can be preserved during sterilisation, according to the invention a stabilising moulding made of sterilisable plastic heat-resistant in the temperature range of sterilisation is inserted in the hollow-cylindrical wall part before heating to approximately 120 DEG to 130 DEG C. If polyurethane is used as the plastic material for the pourer, polypropylene is used as the material for the stabilising moulding. There is proposed as an aid for sterilisation a stabilising moulding which is designed as a thin-walled cylindrical ring (13) which can be inserted into the hollow-cylindrical wall part (3) of a pourer (1) and of which the axial length corresponds approximately to the axial length of the inner cylinder part (7) and the outside diameter corresponds to the inside diameter of the hollow-cylindrical wall part (3) which is formed from sterilisable plastic heat-resistant in the temperature range of sterilisation. In a pourer (1) made of plastic, for example polyurethane, the moulding is designed as a metering element, for example a drip-feed insert (14), can be inserted into the inner cylinder part (7) of the pourer (1) and is produced from a sterilisable plastic heat-resistant in the temperature range of sterilisation. Polypropylene is used as the plastic material for the stabilising mouldings. <IMAGE>

Patent DE-3125690-A1 (DE)
Title: Roadway comprising ground-covering slabs
Inventor: HENNING ALFRED DR ING
IPC: E01C9/08
Filed: 1981-06-30
Abstract: The invention relates to a machine-layable roadway comprising ground-covering slabs, in particular hexagonal slabs known per se, which can be releasably interconnected by mutual hooking and to the production of jointedly interconnectable roadway sections comprising loosely hooked-together single slabs, these sections being secured against disassembly. It was hitherto necessary for the said hexagonal ground-covering slabs to be joined together manually one at a time to form roadways. The laying, repair and recovery of these roadways requires a very high number of personnel and is very time-consuming. The invention makes it possible for the handling of the hexagonal slabs during storage, during transport and, above all, for tactical use to be improved insofar as the personnel and time requirements for laying, for repairing and for recovering such roadways can be minimised. According to the invention, interlocked roadway sections with straight terminating edges are produced which, having been joined together, can then be laid and recovered by machine.

IPC: E06B9/68
Filed: 1981-07-27
Abstract: The invention relates to a closure device for windows, doors or similar openings, which can be moved from a compact, stored position into a sheet-like extended position and vice versa. The closure device has pressure chambers which can be actuated by pressure medium, with the result that the movement procedure of the closure device can be carried out by means of supply and discharge of pressure medium (see Figure 1). The decisive advantage of the invention is that a multiplicity of closure devices can be supplied by a single pressure-medium unit and only one drive motor is thus necessary for a multiplicity of closure devices. <IMAGE>

Title: Serial interface
Inventor: HADERER ANTON ING GRAD
IPC: H04W88/10
Filed: 1981-09-25
Abstract: The invention relates to a serial interface for data transmission between central control devices (FDS) and a multiplicity of peripheral units (FKS). An interface of this type is to be produced for data exchange between the radio data controller (FDS) and the peripheral units (FKS) within one radio concentrator for a mobile radio network with a number of radio concentrators (stationary switching devices) spatially disposed in relation to one another in the manner of a cellular system. For this purpose, the invention provides for data to be transmitted from the peripheral devices (FKS1... FKS120) to the central control device (FDS1, FDS2) via a controllable multiplexer (M1, M2) connected upstream from the central control device (FDS1, FDS2) and in the opposite direction via permanent lines (party lines). The multiplexers (M1, M2) are controlled in an adjustable time plan. The individual peripheral devices (FKS1...FKS120) are checked for the presence of a message to be transmitted or are informed of the presence of a message intended for them. <IMAGE>

Title: Latent heat storage elements
Inventor: STEFFEN GERD DIPL ING
IPC: F28D20/02
Filed: 1981-10-07
Abstract: A latent heat storage element consists of a closed container capable of expansion and containing the latent heat storage material. The increased storage capacity of this element consists in the utilisation of the melting point of the latent heat material, which means: for each temperature level use is made of a different latent heat storage material. The supply and removal of heat is performed by means of the fluid medium surrounding the latent heat storage element. A store consists of many of these latent heat storage elements, which are stacked in a tank and surrounded by a fluid medium. This invention can be applied wherever heat is to be stored in large amounts and in small containers, in order to keep it at a constant temperature and to extract it once again at a different time. <IMAGE>

Patent DE-3145923-A1 (DE)
Title: Anchoring system for an anchor tension member, in particular for a rock anchor
IPC: F16B31/02
Filed: 1981-11-20
Abstract: In mining, the rock pressures are only held temporarily, e.g. for the support of roadways, in the course of which the rock continues to deform. On the one hand, these deformations must be permitted so that a new state of equilibrium can set in; on the other hand, the extent of the deformations exceeds the extensibility of the steel anchor bars. According to the invention, the anchoring element (5) for a steel bar (1) provided with force-transmission ribs is elastically deformable in at least one radial direction. It undergoes an expansion as a result of the ring tensile force occurring when a certain longitudinal tensile force, caused by the sloping flanks of the force-transmission ribs (2), is exceeded. The force-transmission ribs (2) are thereby disengaged from the recesses of the anchoring element (5), which is displaced be a certain distance along the steel bar in a sliding manner via the force-transmission ribs. As a result of accompanying reduction in the longitudinal force, the force-transmission ribs come into engagement again at an another point with the recesses of the anchoring element. With regard to a larger rock pressure area, a uniformly continuous relief of the surface under the rock pressure is thereby obtained when there are several anchors of this type. <IMAGE>

Title: Roadway support system
Inventor: WELCH MICHAEL ADRIAN
IPC: E21D23/04
Filed: 1982-01-11
Abstract: The invention relates to a roadway support system, in particular for use at the road head or in the area of a gate road, with elements which underpin the roof and are formed in a curved shape like the roof. The surface of each element is formed by a curved steel plate, to the underside of which I-section girders are fastened which extend across the element at each end of the same. The lower portions of the elements underpinning the roof are straight and are supported on base elements. Each base element is coupled to the element underpinning the roof via two lifting cylinders which are fastened to the base element in an articulated manner. In addition, each base element is coupled to the element underpinning the roof via a sliding guide which limits the relative movement between both elements to a movement in the operative direction of the lifting cylinders.
