Title: Dental modelling system avoiding inaccuracies due to expansion of plaster - incorporates pin plate with perforated holes held onto impression tray by adaptor ring
Inventor: SCHREIBER HANS DR DR
IPC: A61C9/00
Filed: 1992-06-04
Abstract: The modelling system is used by dentists to produce impressions of teeth and tooth stumps for prodn. of crowns etc. After prodn. of the wax model in the modelling tray (1) a positive model is produced by pouring plaster onto the wax mould. The models of the tooth stumps are reinforced by pins (10). The pins fit into a pin tray (3) which has perforations to accommodate the top ends of the pins. The plate is held on the modelling tray by an adaptor ring. The top parts (6) of the pin holes are cylindrical, leading into conical portions (5) with the larger part at the bottom. The pins may burn away when the plaster sets and is fired. USE/ADVANTAGE - Dental modelling system avoiding inaccuracies due to expansion of plaster.
Patent DE-4218500-A1 (DE)
Inventor: BORGHETTO LUIGI
IPC: G05B19/02
Filed: 1992-06-04
Abstract: A remote control uses a recognition code which consists of a fixed portion and a portion varying with time. The time code is generated simultaneously by a counter (7) in the transmitter (2) and a counter (30) in the receiver (3), both counters being synchronized with each other at the customization stage and subsequent to each operation of the remote control. The recognition code transmitted is thus correlated at all times with the instant in which the code is transmitted, and so varies with time for safeguarding against unlawful entry by copying the recognition code. <IMAGE>

Title: Wood preservative contg. copper salts of di:carboxylic acid hydrazide - are solubilised in base for application, but revert to insoluble, fixed form in the wood, resistant to leaching by rain etc.
IPC: C07F1/00
Filed: 1992-08-01
Abstract: Copper contg wood preservative consists of water-insoluble, or sparingly soluble, copper salts (A) of internal dicarboxylic acid hydrazides (mole ratio 1:2) dissolved in an excess of base. These solns are applied to wood, or wooden articles, by standard methods. In the wood the sparingly soluble or insoluble salts are reformed, so become fixed. Preferred solns ready for use contain 0.05-3 (esp 0.2-0.5)% copper and pref hydrazides are from maleic or phthalic acids (opt substd on C atoms). USE/ADVANTAGE - The compsns are used to preserve wood (claimed) against a wide variety of fungi and insects. When the insoluble salts are reformed, the copper becomes non-extractable and will resist leaching by rain, soil moisture and flowing water. Fixation is significantly better than in known preservative and a fixative, eg chromium, is no longer needed.

The sleeve is then pushed against the inflated bag to force the filler (F) against stop-ring and bead core (W) to bond to the latter. d) After bonding and releasing pressure, drum is turned opt. to position (C). A cut length of reinforcing strip of e.g. rubberised cotton cloth, is wound onto a drum opposite drum. The bead core (W) and filler (F) are transferred megnetically over the strip, which is shaped over both sides of the bead by heated, inflated bags. After bonding, the bead assembly is returned to drum. e) The drum turns to position (D) where is is released by segments and transferred magnetically to a storage rail where it is interleaved with separators, which are transferred by suction pad. USE/ADVANTAGE - Automatic prodn. of tyre bead assemblies. Increased productivity. Small floor space. Increased and uniform quality. Increased dimensional accurac

Title: Change-speed gearbox screwing bottle caps home - uses lower speed for fitting and final tightening than for remainder of operation
Inventor: MAYER EBERHARD DR
IPC: B67B3/20
Filed: 1992-09-29
Abstract: The velocity ratio is varied during the screwing operation. It gives a lower output speed during the initial fitting of the cap and its final tightening, and a higher one during the rest of the operation. Speed-changing may be performed by a feeler pin (10) bearing against the cap (8) and actuating a clutch (3) of the sliding-wedge type. There can be a slipping clutch or friction brake reducing the speed of the tool head to the lower level, and also limiting the final tightening torque. USE/ADVANTAGE - Automatic bottling machine with simple mechanical gearbox change speed mechanism to vary screwing speed during fitting and screwing up of caps.

Title: Method and device for detecting an inaminate object having dynamic properties in the ground
Inventor: FISUN OLEG IVANOVIC
IPC: G01S13/02
Filed: 1993-03-22
Abstract: A description is given of a detection method for an inaminate object with dynamic properties below a floor area on the basis of evaluating the frequency spectrum of microwave radiation irradiated into the floor area and reflected from the structure. In the method, the evaluation is performed with respect to a frequency spectrum which is modulated onto the reflected microwave radiation by means of mechanical vibrating processes inside the structure.
