Patent DE-3215777-A1 (DE)
Title: Fluid cement mortar
Inventor: GREGOR ALEX DR
IPC: E04F15/12
Filed: 1982-04-28
Abstract: The classical method for laying cement screeds is very time-consuming, because the individual working steps involve laborious spreading, compacting, skimming and smoothing. The self-flowing and self-levelling fluid screeds save all these working steps, by means of simple casting or pumping. The invention relates to the composition of a mortar, using particularly cheap additives, which allow masses free of strains and cracks to be produced. According to the invention, this object is achieved by replacing the Portland cement, which greatly shrinks during solidification and hardening, by an easily expanding binder mixture. In addition to the Portland cement, the binder mixture also contains alumina cement, calcium sulphate, hydrated lime and hydraulic additives.

Title: Optical target tracking device
Inventor: ACKROYD JOHN
IPC: G01S17/66
Filed: 1982-09-14
Abstract: In an optical target tracking device, an electronic spatial real-time light modulator 4 stores an image of a scene viewed, and in accordance with this image, a beam of coherent radiation 21, which is generated in the device, is modulated. The resultant signal beam is subjected to a Fourier transformation, for example through an objective 8, and supplied to an optical transformation filter which is adapted to an object, for example a possible target, which is to be detected within the field of view. The transformation filter can be a photographically preshaped image which is adapted to the general characteristics of a possible target. Preferably, however, a further electronic spatial real-time light modulator 9 is provided for this purpose, in which a Fourier transformation hologram image, which corresponds to the target, is generated during an image generation or updating stage. This is done by using an optical switch 11 in order to supply a reference beam 20 of coherent light to the further modulator alongside the signal beam.

Patent DE-3304673-A1 (DE)
Title: Sheet piling method
Inventor: BAUCKE HORST
IPC: B65H31/32
Filed: 1983-02-11
Abstract: The invention relates to a method for the exchange and removal of a pile of sheets formed on a pallet without losses and with continuous feeding and piling of sheets on another pile. When a pile of sheets has been completed, several sheets are clamped by a pair of clamping jaws which have been slid on. An air fin is inserted between the pile of sheets and the sheets held in the clamping jaws, and this supports the new pile of sheets which is being formed. After removal of the finished pile of sheets, a pallet is pushed underneath the air fin, and the air fin is pulled out. When the pallet supporting the new pile of sheets which is being formed has been lowered somewhat, the pallet is displaced until it extends slightly further than the rear edge of the pile of sheets, while clamping is continued. <IMAGE>

Patent DE-3320083-A1 (DE)
Title: Device for pneumatic (hydraulic) displacement of machines or machine parts, having integrated electronic measurement of the displacement path and control (positioning) by means of the (preselectable) electronic path-measuring pulses
Inventor: GRESSER GERMAN
IPC: G01B7/02
Filed: 1983-06-03
Abstract: In the displacement of machines or machine parts with the aid of a pneumatic cylinder, path measurement of the displacement path that is as exact as possible is frequently required for the purpose of precise positioning. Reed contacts are frequently used here, but they have a relatively high switching-point inaccuracy. In order to solve this problem, use is made according to the invention of an incremental rotary position transducer having a gauge roll, and in this case the linear motion of the pneumatic cylinder is transmitted by means of a steel cable onto the gauge roll of the rotary position transducer.

Title: Artificial bait for fish and process for producing such a bait
Inventor: FRENZEL BERND DR
IPC: A01K85/01
Filed: 1983-09-14
Abstract: In an artificial bait for fish, which bait contains a base substance in which additives such as flavour substances, colorants or the like can be incorporated, it is provided that the base substance is composed of proteins and/or polysaccharides and/or lipids as a gel. As a result, a bait is produced which matches in overall consistency the natural feedstuffs of the fish, can be produced without difficulty in any desired shape, indicates optically to the angler the continuing loss of flavour and/or aroma substances in the water and at the same time can be cheaply and simply produced. Furthermore, a process for producing such an artificial bait in maggot shape is described, in which an aqueous solution at a concentration of 0.5 to 3% by weight of sodium alginate is pumped by means of a peristaltic pump through a tube into a 5% strength Ca solution. By this means, a continuous extrudate of the artificial bait is produced in maggot shape having a completely uneven diameter over its entire length, which results in a particularly good approximation to the natural shape of the maggots.

Title: Arrangement of integrated line semiconductor circuits in a module housing
Inventor: BRESCH WERNER
IPC: H03K17/732
Filed: 1983-10-01
Abstract: The known turn-off back-up to shorten the critical hold-off interval in the case of main thyristors fired by auxiliary thyristors requires an auxiliary terminal on the component for feeding negative control pulses. In the arrangement of integrated main thyristors with auxiliary thyristors in standardised module housings there is generally no space available for auxiliary terminals. The solution according to the invention provides for each integrated circuit (2) to have a diode (5) arranged inside the module housing (1), which makes it possible to feed both positive firing pulses and negative control pulses to the module (1) via a common control terminal (G, HK). <IMAGE>

Title: Modulation method for mains-dependent signal transmission and a circuit arrangement to carry out the method
Inventor: KUTSCHERA KARLHEINZ DR
IPC: H02J13/00
Filed: 1983-12-27
Abstract: In the modulation method according to the invention, signals are transmitted at frequencies which are proportional to the mains frequency. Each signal comprises a plurality of simultaneously transmitted narrowband sub-signals whose frequencies f00 to f13 differ from one another, are proportional to the mains frequency and do not correspond to the harmonics of the mains frequency. Each receiver accepts a signal when it simultaneously receives a predefined number of these sub-signals. Since the individual signals may be designed in narrowband form, the signal noise level remains low. The system is highly immune to indeterminate signal attenuation and interference signals. <IMAGE>
