Patent DE-3137058-A1 (DE)
Title: Temperature-compensated liquid-crystal display
Inventor: LEENHOUTS FRANS DR
IPC: C09K19/54
Filed: 1981-09-17
Abstract: In liquid-crystal displays (LCDs) having a twisted liquid-crystal structure, the threshold voltage is temperature-stable if the helix pitch decreases in a certain manner with increasing temperature. In order to achieve such a temperature behaviour, it is proposed to use the following mixture for the liquid-crystal: a chiral compound whose molecules contain at least three chiral centres (centres of chirality) is added to a nematic carrier. At least one of these centres is laevorotatory and at least one further centre is dextrorotatory. The admixed molecules preferably have a bicyclic structure with two wing groups, each of which contains at least one asymmetric carbon atom in the even or odd position - counted from the ring end of the group.

Patent DE-3207867-A1 (DE)
Title: Concrete or rock anchorage as adhesive anchor
Inventor: SCHNABEL WINFRIED DIPL ING
IPC: F16B13/14
Filed: 1982-03-05
Abstract: The invention relates to an anchorage as an adhesive cartridge, in order to anchor threaded rods or the like in concrete or rock by means of a two-component plastic. The object is achieved according to the invention by two flexible tubes which are arranged concentrically to each other being filled separately from each other through the walling of the inner tube with the components of a thermoset plastic. Both flexible tubes are closed against running-out on both sides by means of just one closure clip in each case. As backing fabric, a perforated metal tube sleeve having sharp-angled edges envelops the tubes of plastic. The metal tube sleeve is closed by closure plugs, the one closure plug acting in a self-spreading, centring and sealing manner. When a threaded rod is screwed in, the flexible tubes are destroyed into tiny parts by the tip of the threaded rod and by the sharp-angled edges of the metal tube sleeve. Due to the mixing of the two components of the plastic and due to the displacement by the perforated metal tube sleeve, a bond is established between threaded rod and concrete/rock by means of the two-component plastic.

Title: Data processing system with connected moving recording carriers as peripheral devices and carrying out input/output operations in streaming mode
Inventor: DEUBLER HANNS-HELMUTH DR
IPC: G06F3/06
Filed: 1982-08-31
Abstract: To make the data transfer in streaming mode as independent as possible of the length of the block gaps in magnetic tapes and the speed of the recording carrier, or in order to save unused revolution times in magnetic discs, in a sequence of several input/output commands of the machine programme controlling the streaming mode, at the beginning of such a sequence in each case two input/output commands are processed by the processor (CPU) without in the meantime waiting for a command execution acknowledgement (T-INT) by the input/output unit (IOP) and transferred as commands (SDV) to the input/output unit (IOP), the second command and possibly subsequent commands as a rule being temporarily stored so that one command is always provided in advance and after an input/output operation has been completed can be immediately forwarded to the recording device (PEx). Control by device lists (PE-LIST1) in the processor (CPU) for determining the commands within a sequence. Use of two different logic device addresses in alternating sequence for the same device (PEx) in order to avoid rejection of the command processing in the processor (CPU) and/or input/output unit (IOP) which are weighted as uniform device addresses (PE-AD) at the relevant processing level (e.g. IOP, CH or CE/PE). Manyfold possibilities of adaptation to given or predetermined sequence conditions within the data processing system. <IMAGE>

Title: Shopping trolley
Inventor: WANZL RUDOLF
IPC: B62B3/18
Filed: 1982-09-02
Abstract: At the upper region of the side walls (7) of the shopping trolley (1), stops (13) are arranged which are directed towards the centre of the basket or to the side walls (7) lying respectively opposite one another. Said stops extend inwards to such an extent that the flap (10) which is mounted on the rear wall of the basket so as to be capable of pivoting upwards into the inside of the basket strikes the stops (13) when swivelling upwards, cf. dot-dashed lines in illustration. By means of this measure, the flap (10) is prevented from being wilfully turned as far as the handle (24). In the past, this led to the flap (10) being damaged. <IMAGE>

Title: Transport stage for the production of paintbrushes
Inventor: GAVA LUCIO
IPC: B65G37/00
Filed: 1982-11-06
Abstract: The present invention relates to a transport stage for the production of paintbrushes. The problem to be solved is to provide a transport chain which is improved in relation to the prior art and which performs all the phases of production of the paintbrush automatically, especially the blocking of the handle and the coating of the bristles in the ring with glue. The solution to the problem is achieved by means of two mutually parallel guides (2, 3), at least one of which is assigned a drive formed by a driving disc (13), on which guides (2, 3) are mounted in series a multiplicity of jaws (6) which have essentially one engagement part of a shape complementary with the guides (2, 3) but which are formed at the front such that they can receive the lateral ends of the ring (10), the ring (10) being transported over the entire work cycle for the reception of the handle (15) and of the bristles (14) due to the fact that the jaws (6) on each guide (2, 3) are permanently located opposite one another. <IMAGE>

Title: Automatic device for connecting at least two model subassemblies, in particular fuselage and wing halves
Inventor: KULPE WALTER
IPC: A63H27/18
Filed: 1983-02-01
Abstract: Medium-sized and large model aircraft are mostly equipped with split wings on account of the transport problems. In flight operation it is essential to hold the fuselage and wings together securely but to absorb reliably movements caused by fluttering components or mechanical loads. The automatic device for connecting model aircraft wings fulfils this purpose by a coupling pin on the wing being inserted into the other part of the device on the fuselage. In this arrangement, the coupling pin is connected to balls in a positive-locking manner, and a tensile force caused by a spring is exerted on the coupling pin, which force (clarity) reliably draws together the two subassemblies of the model aircraft.

Title: Process for milking and apparatus for carrying out the process
Inventor: BILLHARDT JOERG
IPC: A01J5/007
Filed: 1983-07-01
Abstract: The invention relates to a stimulation process without compressed air, which can be used in all milking installations. The process is suitable, in particular, for two-chamber teat cups in the constant or variable pulsation milking process with or without phase shifting. In this process, the alternating compressed air stimulation is replaced by a frequency stimulation differing from the milking pulsation rate, while in contrast to other milking processes, milk is withdrawn immediately and thus the milking time is shortened. The associated control device is suitable for any membrane pulsator. The pulsator is essentially unchanged and only a timer and a switching valve are provided upstream.

Patent DE-3326098-A1 (DE)
Title: Cylinder with closed hydraulic system
Inventor: TEPASS HEINZ
IPC: E21D15/45
Filed: 1983-07-20
Abstract: The control and safety valves of a cylinder with a closed hydraulic system are arranged as a complete control system in the base of the cylinder housing or are integrated in the latter, in which case they are designed altogether or partly as a push-in valve cartridge in order to permit easy installation and beneficial servicing. The necessary pressure passages are likewise integrated in the base of the cylinder housing, regulation of pressure being possible in a simple manner via a hand pump likewise designed as an insert cartridge. A cylinder of this type is thereby especially suitable for installation in underground mining and tunnelling, since its control system is accommodated so as to be safe from damage and improper treatment. Extension of the inner tube with maximum setting force against the cylinder-head stop is reliably prevented via the special design of a tube reaching into the hydraulic storage space as well as the special design of the annular space between outer and inner tube.   <IMAGE>
Patent DE-3331064-A1 (DE)
Inventor: OBSTFELDER GUENTHER
IPC: B60T1/093
Filed: 1983-08-29
Abstract: A hydraulic brake having an electrohydraulic antiskid system with a high switching frequency which is speed-proportional. The switching frequency is determined from the number of cross holes in a gear and the gear speed. The cut-in time is electronically determined in a computer and control circuit by a speed comparison of all wheels, whereby the switching frequencies of the passing teeth of a transport gear to a sensor are used as control impulses. If the computer and control circuit determines a deviation, e.g., if a wheel is being braked too sharply and, therefore, runs slower than the other wheels, a camshaft is rotated only in a forward direction, thus activating an antiskid system. If the difference is zero, the camshaft falls back into its initial position, the antiskid system is cut-out and only the braking system of the piston is operating.

Title: Circuit arrangement for call evaluation
Inventor: LEISTNER RUDOLF DIPL ING
IPC: H04M1/654
Filed: 1983-10-17
Abstract: The invention relates to a circuit arrangement for call evaluation in order to connect an answering machine to the subscriber station in a line-powered telephone station. The object of the invention is to design a circuit of this type in simple fashion, all the criteria required to operate the telephone station being met. This object is achieved by arranging that a tone generator module which is connected upstream of said station and is provided with a filter through which only the tone generator frequency can pass, terminates the subscriber line, when the station is in the idle condition and an AC voltage is supplied by the tone generator module to a rectifier bridge, which generates DC current pulses therefrom when the key provided for connecting the answering machine is pressed and tone ringing is present, as a result of which counting pulses are supplied via a first capacitor for a counter module, the feed voltage for the counter module is supplied via a second capacitor, and a reset pulse is supplied via a third capacitor at the start of the counting. When the answering machine is connected after a specific number of pulses, the tone generator module is deactivated, and, at the end of the call answering, the tone generator module is reconnected by an answering machine pulse. The advantage is that only one input filter is required.
Patent DE-3339066-A1 (DE)
Title: Magnetic field sensor
Inventor: NIEBLER ERICH J
IPC: F42C11/00
Filed: 1983-10-28
Abstract: A magnetic field sensor (1) having two pick-up coils (2, 3) which are connected in opposition in series, especially for obtaining a detonating signal (7) for explosive devices (9) such as mines, is intended to be designed for a high response sensitivity. To this end, it is equipped with two flat coils (2, 3) which are arranged concentrically one inside the other and have very different diameters (d, D), the numbers of turns on which coils are inversely proportional to the mean coil cross-sectional areas. Since, in consequence, both coils (2, 3) - independently of direction in the coil planes - detect parts of the range-dependent response of the field strength originating from the object moving past it, which parts are highly different from one another, the result is a voltage difference (du), which is large in comparison with the noise level, for driving the evaluation circuit (4) and nevertheless for good compensation of the interfering effects from the earth's magnetic field. Higher frequency electromagnetic interfering effects are suppressed by the coils (2, 3) being surrounded by a housing (8) consisting of material which is electrically conductive but cannot be magnetised. <IMAGE>
