Title: Mechanically activatable suction device for raising and holding air-permeable articles
Inventor: MANG PAUL
IPC: B66C1/02
Filed: 1984-11-13
Abstract: Mechanically activatable suction device for raising and holding non-magnetic air-permeable articles, having a casing (2), a suction chamber (14) and a suction aperture (20) in the underside of the casing. The new and innovative nature of this invention resides in the fact that an on-off valve is assigned to the suction aperture (20) and has a valve element (22) which seals the aperture off from atmospheric pressure and has a valve tappet (24) which penetrates the aperture (20) in a downward direction and projects from the casing, and an operating piston (6) which is connected to the valve element (22) and is acted upon by atmospheric pressure on the side facing away from the valve element (22), over its entire diameter (26) when the aperture (20) is sealed off and over a reduced diameter (28) when the aperture (20) is unblocked, and that the surface of the entire diameter (26) of the operating piston is significantly larger than the surface of the aperture (20), which is in its turn significantly larger than the surface of the reduced diameter (28) of the operating piston. An aggregation of such suction devices is especially useful for manipulating pre-drilled printed circuit boards. <IMAGE>

Title: Moulding from plastics wastes and process for the production thereof
Inventor: SCHROEDER HORST
IPC: B29B17/04
Filed: 1985-01-15
Abstract: Mouldings consisting entirely or substantially of plastics wastes are described. In addition, a process for producing these mouldings is also described. The essential feature of the invention is that plastics wastes which were hitherto not reusable, such as thermoplastic-coated paper and in particular polyethylene-coated paper can for the first time be subjected to a recycling to obtain products with a high utility value. This is achieved by mixing different waste materials together in specific quantities and under specific conditions and extruding them to form the desired mouldings. Especially preferred mouldings according to the invention are reinforced fencing posts.

Patent DE-3503321-A1 (DE)
Title: Device for measuring a pressure difference, in particular in air filters
Inventor: BAUMANN PETER
IPC: B01D35/143
Filed: 1985-01-31
Abstract: In order to determine the pressure difference between two spaces, it is known to use the deflection of a diaphragm (6) inserted in an opening of a partition between the two spaces as a measure for the pressure difference between the two spaces. Such a device is designed to the effect that, upon reaching a specific deflection which corresponds to a specific differential pressure, the diaphragm (6) permanently interrupts or establishes the electrical connection between two contact points (8). In this way, it is possible at any time by applying an electrical continuity tester to control whether the predetermined differential pressure has been exceeded or not at any given instant. Such a device is intended for use, in particular, in controlling the pollution severity of an air filter. <IMAGE>
Patent DE-3503585-A1 (DE)
Title: Multi-chamber light for motor vehicles
Inventor: PETERSEN PETER
IPC: B60Q1/26
Filed: 1985-02-02
Abstract: The invention relates to a multi-chamber light for motor vehicles, in which a light chamber is formed by a lens which has a meander-shaped cross-section, and a parabolic reflector. The filament of a fog tail light filament lamp is arranged at the focal point of the reflector. In the light chamber, a tail light filament lamp is additionally inserted at a distance from the fog tail light filament lamp. A second lens with light-directing prisms is arranged between the two filament lamps and the lens with a meander-shaped cross-section. Areas of the second lens with light-directing prisms are each connected in front of the sections, extending parallel to the optical axis of the reflector, of the lens constructed with the meander-shaped cross-section. The prisms concentrate the light emerging directly from the filament of the tail light filament lamp onto the optical axis of the parabolic reflector. The light beams, directed in parallel by the reflector, of the fog tail light filament lamp pass through the areas remaining free from a light-concentrating optical system between the prisms on the second lens.
Patent DE-3507100-A1 (DE)
Title: Operational network for a parallel processor
Inventor: GLAESER WINFRIED DIPL ING
IPC: G06F9/308
Filed: 1985-02-28
Abstract: The operational network can be used for the parallel processing of character strings stored in a memory. The operational network consists of a number, corresponding to the number of the character strings (ZK) to be processed in parallel, of field modules (FMOD) of identical construction, of a logical network (VW) and of a controller (SW). The operations which can be executed separately for each character string are carried out in the field modules (FMOD). This includes, for example, the determination of the largest or smallest key word or the sorting of the key words. If operations are to be carried out in which the character strings must be used jointly, the logical network (VW) works together with the field modules (FMOD). The logical network receives the processing bits (VBIT) taken from the character strings from the field modules and from these generates the logic operation word (KBT). Such operations are, for example, the OR function or the NAND function. Using the controller (SW), the bit-by-bit evaluation of the characters of the character strings is controlled either in the field modules alone or jointly in the field modules and in the logical network. <IMAGE>

Title: Beneath-roof element
Inventor: JOSS SANDRO
IPC: E04B7/22
Filed: 1985-03-16
Abstract: The beneath-roof element which can be laid directly on roof rafters is a combination of a flexible beneath-roof sheet (2) on a supporting layer (3), of a core layer (5) which consists of fibre insulating material and is reinforced by webs (6), and of a visible-underside layer (7) which acts as a vapour barrier. The visible-underside layer (7) is designed as a supporting hard layer, e.g. as a polyester panel. The fibre insulating material (5), e.g. rock wool or glass wool, has a compressive strength of at least 2 x 10<4> Pa at 10% compressive strain. The beneath-roof sheet (2) is adhesively bonded to the fibre insulating material (5) via a fixed supporting layer (3), e.g. a polyester layer, which serves, in particular, as a backing for welding the flexible beneath-roof sheet (2). This beneath-roof element, with optimum heat insulation, does not have the disadvantage of cold bridges and, having conventional dimensions, is additionally designed as a self-supporting element. By connection of the uppermost layer, the beneath-roof element permits a roof, which is to be erected, to be sealed off in a watertight manner towards the outside. <IMAGE>

Title: Amplifier circuit for a high-impedance sensor
Inventor: PALATA JAROMIR DIPL ING
IPC: G06F3/033
Filed: 1986-01-15
Abstract: The amplifier circuit for a high-impedance sensor, for example a piezoelectric sensor (1), exhibits an operational amplifier (7). A positive feedback loop which consists of a first resistor (R1), a second resistor (R3) and a capacitor (C1) is connected between the positive input (5) of the operational amplifier (7) and its output (11). The output (11) of the operational amplifier (7) is connected to the negative input (9). A switch (17) connects the positive feedback loop to earth in dependence on the signal (A) at the output (11) of the operational amplifier (7) and, as a result, renders this loop ineffective. As a criterion for this disconnection of the positive feedback loop, the change in the sign of the slope of the signal (A) at the output (11) can be used, for example. The advantage of the circuit is a very high input impedance whilst at the same time eliminating the risk of unwanted switching processes due to damped slow oscillations at the output (11). The amplifier circuit is preferably used with a touch-sensitive device. <IMAGE>

Title: Oscillating-vane pump with a sensor cell
Inventor: HOELTER HEINZ DIPL ING
IPC: B60H3/06
Filed: 1986-02-12
Abstract: In the main application P 3514588.9, a sensor cell with oscillating-vane pump gas metering is described. It is known that semiconductor sensors exhibit sensitive reactions to temperature fluctuations and different air-flow speeds. In addition, their response times are too high particularly in the region of low concentration, and their decontamination times are too high to be used for example to control the air feed of vehicle cabins in road traffic. It has been discovered that a substantially more rapid rinsing away of the extraneous material located on the surface of the sensor is achieved if the air masses in front of the surface of the sensor are made to oscillate.

Title: Conveying zones with buffer behaviour
Inventor: HOLZHAEUSER DIETER ING GRAD
IPC: B65G47/26
Filed: 1986-03-18
Abstract: The conveying zone according to the invention is subdivided into a plurality of conveying sections 2 over which the unit loads can be conveyed only in the form of uniform groups which are formed by the sources 1. Since the groups can be transferred from section to section for as long as entirely empty sections are present in the conveying direction, the entire conveying surface of the system is used as a unit load store. The system works automatically, since it is possible to differentiate with certainty between a section filled with a group and an emptied section since, for this purpose, only the stored information concerning previous correct transfers is used and not a current, possibly unreliable, interrogation of a light barrier. <IMAGE>
Patent DE-3617277-A1 (DE)
Title: Forward-feed device for a ribbon saw
Inventor: REIFENHAEUSER TONI
IPC: A22B5/20
Filed: 1986-05-23
Abstract: A conventional ribbon saw (1) is assigned a forward-feed device which consists essentially of a guide channel (3). A length of material can be moved axially against a stop (5) via the guide channel (3) by means of a forward-feed plate (4) in such a way that one end of the length of material intersects the plane of an active side (7) of the ribbon saw (1). The guide channel (3) can be displaced perpendicularly to its longitudinal extent from its initial position into a limit position. In this process, a disc-shaped piece is cut off from the length of material by the side (7) of the ribbon saw (1). Before being guided back in the direction of the initial position, the guide channel (3) is moved away coaxially from the ribbon saw (1) and only subsequently pushed back perpendicularly to its longitudinal extent. The guide channal (3) finally reaches its initial position by means of renewed axial displacement in the direction of the plane of the side (7) of the ribbon saw (1). <IMAGE>
