Title: Grinding edges of lenses - involves toothed belts to rotate upper and lower lens supports at same speed
Inventor: BORN ERNST
IPC: B24B9/14
Filed: 1990-07-21
Abstract: The edge (6) of a lens (1) is ground on a machine which is provided with a turntable (30) which has a ring of through holes (31) with ledges to support the lenses (1). Each lens is brought in turn to the grinding station by the rotation of the turntable. During the grinding operation the lens (1) is held between a fixed upper support (5) and a lower support (2) which is pressed upwards by a hydraulic or pneumatic cylinder (3). The lower support (2) is pushed upwards through the hole (31) in the turntable (30) so that it is held clear of the turntable. The upper (5) and lower (2) supports are rotated at the same speed by means of a motor (27), a driving shaft (21) and toothed belts (7, 26). USE - Grinding the edges of lenses.
Patent DE-4025477-A1 (DE)
Inventor: ROTH HEINZ DIPL ING
IPC: E05B49/00
Filed: 1990-08-10
Abstract: What is described is an access control device for doors which are equipped with an electrical door opener (11). To prevent an unauthorised actuation of the door opener, for example by applying a supply voltage, each door opener is activated from a central control unit (10) by means of an individual selection code. The absence of any coincidence between the transmitted selection code and a code preset in the door opener prevents the possibility of actuation. <IMAGE>

Title: Profile measurer for elongated materials - uses laser light with division of reflected light and focussing into lines perpendicular to two receiver lines at right angles
Inventor: MOLL REINHARD DR RER NAT
IPC: G01B11/24
Filed: 1990-08-14
Abstract: Measuring the profiles of elongated material involves passing a light spot (8), pref. of laser light, over the profile at an angle and detecting the reflected light in the plane defined by the material and light source. The reflected light is focussed (12) to form a line (13) perpendicular to a one-dimensional receiver line (14) connected to an evaluation device. A beam splitter (11) arranged in front of the focussing device deflects light via a second focussing device (12') to form a second line (13') perpendicular to a second receiver line (14') and to the first line. USE/ADVANTAGE - Contactless measurement arrangement improved to enable high accuracy measurement in two dimensions with equal accuracy.

Title: Data processor with insert circuit boards - has central battery for supply of all memories on circuit boards, with individual circuit boards fitted with buffer batteries
Inventor: KUGLER ROLAND
IPC: G11C5/14
Filed: 1990-08-24
Abstract: The processor has control points to a higher unit and to peripheral appts.. A central battery supplies all semiconductor memories (4) on all inserting circuit boards (1) of the system. In addition each individual circuit board has its own buffer battery (14). At a higher voltage on the supply voltage terminal (3) it is decoupled by a diode (11), which is polarised opposite to the forward direction. The buffer battery is pref. in series with the diode and at least one PTC resistor (12) and a normal resistor (13). One resistor limits the current fed into the buffer battery to a permissible value on short circuiting the diode. Typically, the buffer battery on each circuit board is coupled to such sockets of the 24 V control position, which is not used for data exchange. ADVANTAGE - Highly reduced data loss in semiconductor memories on central failure or circuit board withdrawal.

Title: Furnace for the combustion of solids, waste materials, other residues - and the recovery of heat energy
Inventor: HARLANDER NORBERT
IPC: F27B3/00
Filed: 1990-12-04
Abstract: In a two-stage furnace in which solid wastes are burned a solids separator is located after the prim. section in which materials are pyrolysed or calcined.

Patent DE-4107217-A1 (DE)
Inventor: LEONHARD VOLKER DIPL CHEM DR
IPC: G01N27/41
Filed: 1991-03-07
Abstract: The limiting-current probe proposed has a fixed-ion conductor (1) fitted with electrodes (2, 3) on two opposite faces. By fixing its porosity, the fixed-ion conductor not only fulfils its function as an ion-conducting medium but also acts as a porous diffusion barrier. The probe also has, located on one (2) of the two electrodes, a layer (4) which is impermeable to the test gas, this electrode (2) being the measurement electrode at which the electrochemical reaction from the gas phase into the fixed-ion conductor takes place, the electrode being negatively biased when it conducts anions and positively biased when it conducts cations. This gives a compact probe which can be manufactured using screen-printing techniques and in which a separate diffusion barrier is not necessary.

Patent DE-4117099-A1 (DE)
Inventor: FEY WOLFGANG
IPC: B60T8/88
Filed: 1991-05-25
Abstract: A circuit (3) for an electronic regulator (1) is fitted with a monitoring circuit (4) which, on recognising a defect, an error in operation or a defective power supply, holds the operating components controlled by the regulator, like the magnetic valves (L1, L2 ... Ln) of an anti-lock braking system, to their inoperative position or resets them to this position. Before a power supply relay (Rel) is switched on, the monitoring circuit (4) first checks the connection of the relay to the power supply (IGN), the locked position of a switching transistor (TR) via which the power supply relay (Rel) is switched, and the separated position of the power supply contact (a). In addition, the monitoring circuit (4) reacts to overvoltages (SÜ).

Title: Hard porous granulate - comprises clay with combustible fibres which burn on firing to leave pores
Inventor: FREY ALFRED
IPC: C04B18/02
Filed: 1991-05-31
Abstract: For the production of a hard and porous granulate material, clay is thoroughly mixed with combustible fibres and water into a wet mass which is then reduced and granulated to form a wet mass of rounded particles to be dried at least partially. The dried particles are fired so that on one side, the clay is fired, and on the other side, the fibres are burned out to form the pores. The pref. fibres contain cellulose, such as paper fibres or sawdust. For the clay, at least the clay content of a gravel wash sludge is used. The fired clay contains burnt residue within its pores. USE/ADVANTAGE - The material has a high water absorption but does not compress and, when it degrades, its material is returned into the earth without damage. The material absorbs high volumes of water, and is cheaply produced.
