Title: Prodn. and checking of permit cards - forming coding by surface impressions and checking by sensing block positioned like original punch
Inventor: STOCKBURGER HERMANN
IPC: G07B11/11
Filed: 1979-04-27
Abstract: Access or permit cards are produced on a hand-operated press unit and the cards are checked by a sensing system when used. The card (23) is inserted onto guide pins (21, 22) on a bearing block. The coding is formed on the card by a punch (31) with projections that make a surface impression on the card. Force is applied to the punch by operating a lever (36) to move the actuator rod (28) downwards. Adjusters (41, 42) control the amount of motion to limit the depth of the impressions. The card checking unit has a sensor head of the form of the punch. Proximity sensors are used to check that the sensor head moves the required distance ensuring that the impression coding is correct.

Patent DE-2931709-A1 (DE)
Inventor: SCHMIDT KLAUS-DIETER
IPC: G01R31/333
Filed: 1979-08-04
Abstract: It is known to test electric circuit breakers synthetically for power switching characteristic and insulation strength in the same test circuit. The insulation strength test necessitates a great effort and is carried out more infrequently than the test for power switching characteristic. To eliminate this disadvantage, it is proposed to test for insulation strength in a first test circuit and for power switching characteristic in a second one. In addition to a normal test circuit for power switching capability, a circuit for testing for insulation strength is used wherein the circuit breaker (1) is connected to a high-current source (30) via safety switches (32) of relatively low voltage strength and a resonant circuit (34, 36). The chambers (5a, 5b) are supplied with the short-circuit current and opened. An oscillating switching surge is applied to the encapsulation (2) via a resonant circuit (50, 52) by means of a surge generator (46). The two terminals (4) are loaded virtually identically compared with the metal encapsulation. No blocking switch is necessary and a high-current source of relatively low power can be used. <IMAGE>

Title: ultrasonic scanner for objects and medical use - has additional variable delay elements in each channel for fine phase correction
Inventor: ANDERSON WESTON ARTHUR
IPC: G10K11/34
Filed: 1980-02-08
Abstract: The sound energy reflected from various points within the body arrives at the transducers at different angles and has to be phase corrected. The delay elements normally used for this purpose are supplemented here by additional variable delay elements in each channel to provide fine and precise phase correction. Isolating inverters may be switched into each channel to prevent crosstalk, esp. for very small or very large angles of incidence. The additional delay elements for fine adjustment are wire in series with the main delay elements whose output may be switched by FET's depending on whether the angle of incidence is zero or very large. A correction of within 1/8 of a wavelength at a frequency of 10 MHz may be achieved.

Title: Paper carton container for alcohol-free beverages - with internal jointing edge thinned down and folded over
Inventor: TAKE YOSHIAKI
IPC: B29C65/00
Filed: 1980-06-25
Abstract: The laminated material forming the body of a cylindrical container has an innermost layer of synthetic thermoplastic resin. The end of the blank which is to be glued inside, is reduced in an edge zone to about half its thickness. A long groove is cut along the centreline of the edge zone, and after the application of an adhesive, the end is folded over at the groove, so that the two ends of the blank can be glued together with the folded over edge inside. Circular end covers with double flanges are then fixed on the ends of the cylinder. From the outside to the inside, the laminate may comprise a layer of synthetic thermoplastic resin, a layer of paper, a layer of adhesive, a layer of metal, a layer of heat resistant adhesive and a layer of synthetic thermoplastic resin. The process is eminently applicable to the production of containers for alcohol-free drinks. The fitting of a covering strip for the joint inside is made unnecessary and its loosening during subsequent processing of the container so that leaks occur, is avoided.

IPC: A47J37/12
Filed: 1981-02-02
Abstract: A deep-fat fryer having a transparent lid, in which a filter pad is arranged so as to be exchangeable, is to be improved to the extent that, despite a considerable simplification in manufacture, a very good view into the closed deep-fat fryer is made possible. In order to achieve this object, the transparent lid (2) of the deep-fat fryer according to Figure 1 is designed in two parts and consists of a hood (6) made of non-transparent material with at least two window openings (5) and of a receiver (6) with at least two window openings (5) and of a receiver (9) for the filter pad (10) and of an insert (8) which, in turn, is produced from transparent material and, in the region of the window openings, has projections (7) which can be snapped into the window openings (5). Additionally, the insert (8) is fitted with a counter bearing (11) for the filter pad (10). It is achieved by means of this design that the production of the transparent lid (2) is simplified and made less expensive since that part is used for forming and sealing the window (4) which is also used for fixing the filter pad (10). Furthermore, the advantage is achieved that the view into the closed deep-fat fryer is improved since at least two window openings (5) are provided, thus increasing the incidence of light into the interior of the deep-fat fryer. <IMAGE>

Title: Heat exchanger for liquids
Inventor: SONJE BERND
IPC: F28D7/02
Filed: 1981-02-06
Abstract: The invention relates to a heat exchanger for liquids. The object is to provide between two fluid media a heat exchanger of variable output which is easy to fit in conjunction with a simple design, and guarantees effective heat transfer between the fluids. In order to achieve this object, the essence of the invention is that the heat exchanger produced from plastic or metal consists of a channel block having juxtaposed channels, as well as of two covers which have an inlet and outlet for the liquids, there being provided in the inlet or outlet in each liquid path at least one cross-sectional constriction for the purpose of matching the resistance of the channels, which are situated parallel to one another in terms of flow. The technical advance hereby achieved is to be seen in that the channel member can easily be varied for the purpose of achieving different output stages, without the connections thereby having to be altered. The heat exchanger can be produced using the modular system.
