Title: Coin operated stacking supermarket trolley - with plug which connects into socket on second trolley, released by inserting coin which is returned only when restacked
Inventor: FUCHS PETER ING GRAD
IPC: G07F7/06
Filed: 1980-10-10
Abstract: The supermarket trolley (10) has parallel supports struts between the base frame (11) and the basket. On the rear strut is a horizontal plug piece (20) while on the front strut is a locking socket (22). When the trolleys are stacked, the plug connects into the socket on a second trolley. The trolleys can only be released by the insertion into the socket piece of a hireable special key or a large coin which can only be removed when the trolley is restacked. This ensures that trolley are always returned to the store in order to retrieve the coin or return the hired key, thus freeing the car park of loose trolleys and avoiding the employment of collectors.

Title: Contactless measurement of contact lenses by topographical evaluation - using parallel and perpendicular collimated lens transmission and interferometry
Inventor: ACHATZ MANFRED DIPL PHYS DR
IPC: G01B11/06
Filed: 1980-12-22
Abstract: A collimated light beam is passed through the lens perpendicular to and parallel to the optical axis. The outer shape of the lens is determined from the perpendicular beam shadow image. The radial thickness variation of the lens is determined from the local phase variation of the parallel beam on being passed through the lens. The phase variation is determined interferometrically. The internal shape of the lens is derived from the external shape and the radial thickness variation. The interferometric evaluation involves reference or object wave variation.

Title: Arrangement for detecting the number of actuations of an actuating part of a device which is moved relative to the device body
Inventor: NAGEL GERHARD
IPC: G07C3/10
Filed: 1981-01-28
Abstract: An arrangement for detecting the number of actuations of a device, particularly a labelling device, is described in which each actuation triggers an electric pulse which is supplied to a counting circuit in the form of a static frequency divider. This counting circuit can be connected to an evaluating unit which exhibits a pulse generator which, when activated, supplies a sequence of pulses, the number of which is equal to the magnitude of the divider ratio of the frequency divider, and a counter, the counter input of which is connected to the pulse generator and the begin-counting input of which is connected to the signal output of the frequency divider. The single-pulse generator with the frequency divider requires only minimal space and can be accommodated in the device to be monitored, whilst the evaluating unit with the display, which takes up space, is normally separated from that and only needs to be connected for reading the count.

Title: Process for producing plastic film elements
Inventor: WINTER HEINZ ING GRAD
IPC: B29C67/00
Filed: 1981-03-02
Abstract: The production process relates to plastic film elements which are used in particular in multi-pane thermal glazing. A plastic film is pretensioned homogeneously and flatly on a special device and in this state applied to a metal frame. The metal frame does not undergo any shape change as a result of the tensile forces of the film. By this means the flat state of the film is retained faultlessly. The absorption of the tensile stress without elastic deformation of the frame is achieved by pretensioning the frame in the opposite direction by means of a force corresponding to the tensile stress. The deflection occurring during the frame pretensioning remains low with an appropriate frame construction.

Patent DE-3116485-A1 (DE)
Title: Heat pump
Inventor: STEPHAN ERNST-WILHELM DIPL ING
IPC: F25B41/06
Filed: 1981-04-25
Abstract: In heat pumps, it is customary to make the flow cross-section of the expansion valve (3) adjustable and to increase it, in the case of rising evaporation temperatures, by means of a temperature sensor (5) behind the evaporator (4). As a result, a greater coolant throughput takes place, which leads to greater evaporator capacities. In order optimally to use the evaporator surfaces, the temperature sensor (5) is exposed to a higher temperature by means of an external heating system (6). Even at relatively low evaporation temperatures, it therefore brings about an increase in the flow cross-section. The external heating system (6) can in this case be regulated by a temperature sensor (7) which measures the evaporation temperature directly. <IMAGE>

Title: Variable-gain pulse amplifier
Inventor: GORWAT PIOTR
IPC: A61B7/04
Filed: 1981-06-23
Abstract: For measuring pulse curves, particularly for phonocardiography, the gain must be adjustable within wide ranges for covering curves of different amplitude. To be able to carry out this adjustment automatically, fast and thus gently, for example for patients to be examined, a divider (1) is provided as amplifier which is supplied with the signal to be amplified as numerator (11) and a signal, corresponding to an amplitude range sampled within a particular time, as denominator (12) via a memory (6). The memory content can be exchanged by comparison in a comparator (7). The pulse curve evaluation is further simplified by a calibration signal generator (8). <IMAGE>

Patent DE-3133048-A1 (DE)
Title: Position sensor
Inventor: IWASAKI SHINICHIRO
IPC: G01B7/00
Filed: 1981-08-21
Abstract: A position sensor for detecting an offset (misalignment) of an object is specified which has a movable member connected to the object, a permanent magnet connected to the movable member, and a magnetically soft part surrounded by an electric coil and fixed in the vicinity of the zone of movement of the permanent magnet. Voltage pulses are applied to a turn end of the electric coil, whose other turn end is connected in series with a resistor. The voltage drop across the resistor is determined for each pulse applied to the coil, and the delay time between the rising edge of the applied pulse and the corresponding voltage drop across the resistor is measured by means of a processing circuit which outputs an analog voltage signal or a digital code signal which represents the delay time. An offset of the object produces a change in the magnetic field at the magnetically soft part, which causes a corresponding change in the delay time, which therefore represents a measure of the offset of the object.

Title: Conveying apparatus for bulk materials tending to form bridges
Inventor: TEBBENHOFF EBERHARD DR
IPC: B65G33/18
Filed: 1982-05-17
Abstract: The invention starts from an apparatus for conveying bulk materials tending to form bridges, which consists of a screw pump having at least two spindles lying with their axes in one plane. The spindles have screw profiles engaging in one another and are driven in the same direction. When the bulk material forms a bridge, there forms along the sealing line between the screw profiles a plug which at least partially prevents a take-up of the particles of the particular bulk material in the direction of rotation of the screw spindles and which thereby allows conveyance when the spindles are in synchronism. The plug formed by the bridge of bulk material is now to be compressed towards the delivery point or outlet side of the apparatus. This is achieved by reducing the pitch of the screw profiles, engaging in one another, of the spindles towards the outlet side.
Patent DE-3221739-A1 (DE)
Title: Hollow profile
Inventor: QUANTE HEINRICH
IPC: E04C3/36
Filed: 1982-06-09
Abstract: Structural elements, in particular supporting and bearing elements, can absorb high tensile and compressive forces or flexural forces with considerably reduced use of steel by using a hollow profile which has a cavity closed on all sides and a filling nozzle and an outlet valve, in order to fill the hollow profile with an alpha hemihydrate or a similar construction material which absorbs high compressive forces. In this case, two, preferably opposite, walls are to be designed as rigid and dimensioned essentially corresponding to the precalculated tensile forces, while the side walls connecting these two rigid walls are designed to be stretchable, foldable or slidable one into the other. A corresponding surface-covering hollow profile can be used preferably in underground mining as a lagging element, its special shaping making it ensure a tight connection to the rock both of the hollow profile and of the roadway support. Fig. 1 is intended for publication. <IMAGE>
Patent DE-3223167-A1 (DE)
Title: Method of examining water containing decomposable carbon compounds
Inventor: DUVE HANS
IPC: G01N27/02
Filed: 1982-06-22
Abstract: Decomposable carbon compounds present in the water to be examined are continuously detected, the inorganic carbon compounds being decomposed by acid and the organic carbon compounds by photochemical oxidation during UV irradiation. The volatile decomposition products are continuously partially expelled by circulating gas from the water to be examined. The IR absorption of the circulating gas is then measured and/or the circulating gas is passed into a conductivity cell with fully demineralised water continuously flowing through it and partially dissolved therein, as a result of which the conductivity of the water changes. The inorganic carbon compounds do not have to be removed beforehand in order to detect the organic carbon compounds. The detection time is less than one minute and the limit of detection is down to 1 ppb C, depending on the nature of the carbon compound.
