Title: Nut cracker with ornament-type design - has spring-biased firing pin requiring minimal force for cracking
Inventor: ZIMMERMANN OTTO
IPC: A47J43/26
Filed: 1980-01-23
Abstract: The nut is placed in a socket (3) which is then contacted by a pressure plunger (5) which is connected to a firing pin (4) which moves axially in a bolt guide (3) which is linked to the socket (1). A bolt spring (6) impinges upon the firing pin in the direction of the socket. Thus with the nut in the socket the firing pin is drawn back against the bolt spring and when released jumps back to crush the nut between the pressure plunger and the wall of the socket. The force used for breaking the shell is not a direct result of the force applied by the user but the energy required for cracking is first stored in the bolt spring and converted into kinetic energy.

Patent DE-3040762-A1 (DE)
Inventor: BECKER KURT DR ING
IPC: C03B9/193
Filed: 1980-10-29
Abstract: An arrangement for adjusting the mass of gobs of thermoplastic material, especially molten glass, which are deformed in a positive manner in the mold of a molding machine by means of a pressing member which penetrates into the gobs. A distance transducer mechanically detects the maximum depth of penetration reached by the pressing member during each molding-machine operating cycle. The distance transducer is connected with a metallic actuating element for a differential transducer, at whose output is produced an electrical signal proportional to the maximum penetration depth reached, this signal being applied to an automatic regulating circuit which adjusts the setting of a dosing structure which controls the mass of the gobs. The regulating circuit includes, at the output of the differential transformer and connected one after the next, a measurement transducer, a maximum-value storage, a sample-and-hold circuit, a summing junction, a PI- or PID-regulator and an adjusting motor which drives an adjusting member for the dosing structure, as well as a feedback transducer. The feedback transducer is connected to the PI- or PID-regulator via a rotary-angle-to-voltage converter. A control and display panel is connected to a control logic circuit, the latter connected to the maximum-value storage and to the sample-and-hold circuit, the control logic circuit receiving a machine synchronization signal once per machine operating cycle. A desired-value potentiometer furnishes a desired-value voltage representing the optimum penetration depth for the pressing member, this voltage being applied to the summing junction. A weighting circuit can be provided to take into account the different maximum diameters of different pressing members which may from time to time be used. The feedback transducer is automatically returned to a middle angular setting thereof. The distance transducer can be constructed in several different ways, disclosed.

Title: Flexible container for bulk materials which do not flow easily
Inventor: FRANK HANS-ALBRECHT
IPC: B65D88/16
Filed: 1981-02-20
Abstract: The containers according to the invention are suitable for transporting and storing bulk materials which do not flow easily and which clump or cake together. The aim and object are to combine the good characteristics prevailing hitherto in flexible containers, such as low empty weight, low empty volume and long service life, with the suitability for emptying bulk materials which do not flow easily with sensible load distribution, and simple producibility. The solution according to the invention provides the point-type connection of the cylindrical outer surface of the container to the bottom lid between outer surface and bottom reinforcing straps, partly in a releasable and partly in a fixed manner. Via carrying loops attached to the outer surface reinforcement straps there is a continuous force transmission by belts made of material which is resistant to tension, but is flexible. The container is sealed off well by a sealing apron which is fixed to the outer surface and is folded in when the container is closed. <IMAGE>

Title: Method of generating isothermal useful heat
Inventor: STREICH MARTIN DIPL PHYS
IPC: F25B29/00
Filed: 1981-03-27
Abstract: A method of generating virtually isothermal useful heat by means of mainly sensible low-temperature waste heat of a fluid is indicated. In this case, the fluid is brought into heat exchange with a circulation medium consisting of a mixture of two or more components with different boiling points, which medium in this connection is evaporated and subsequently compressed, cooled in heat exchange with a liquid, condensed, relieved and again brought into heat exchange with the fluid. In order to be able to convert sensible waste heat into virtually isothermal useful heat with justifiable investment expenditure, the evaporated circulation medium is compressed in at least two stages, the part of the circulation medium which is condensed during the heat exchange after the respective compression is separated and the vaporous part is supplied to the next compression stage. In this case, the liquid evaporates in heat exchange with the compressed circulation medium.

Title: Battery-operated electronic apparatus with the voltage supply being protected for sub-functions
Inventor: SPAHRBIER DIETER DIPL PHYS DR
IPC: G04C10/00
Filed: 1981-04-18
Abstract: As apparatus batteries (1) become increasingly discharged, it is intended that the actual basic functions of the apparatus be maintained on reaching a lower limiting voltage, while the additional functions, which consume considerably more energy, are switched off. In the case of an electric clock, in this way, additional loads (4) (such as display lighting and the alarm) are automatically switched off, so that they no longer work despite the operation of the function keys (7) and of the internal setting devices. The actual clock mechanism (2) continues to operate, however. At the same time, the user is informed of the state of the battery (1). The additional loads (4) cannot be brought back into use again until, possibly after the battery (1) has recovered, a voltage value is reached which is above the lower limiting voltage, by closing the controllable switch (6). <IMAGE>

Title: Method for driving a runout-type liquid crystal strip display
Inventor: TAUER KARL M DIPL ING
IPC: G01R13/40
Filed: 1981-05-12
Abstract: Runout-type liquid crystal strip displays can be subdivided into three groups: in the first group (3), all liquid crystal cells are switched on, in the second one (2), some are switched on and some are switched off and in the third group (1), all liquid crystal cells are switched off. For matrix addressing, the row conductors (B) must therefore be supplied with three different voltages which can only be achieved with great expenditure. According to the invention, this expenditure can be reduced by the fact that the drive voltages are generated by constant-height length- and/or phase-modulated pulses (x1, x2; y1, y2, y3). The invention can be used, for example, for analog measuring instruments. <IMAGE>

Title: Crossmember profile for roof and wall shelves
Inventor: BALS REINER RUDOLF DIPL ING
IPC: E04D3/36
Filed: 1981-05-30
Abstract: For shell structures for walls and roofs, the invention provides crossmember profiles which make it possible to connect inner and outer shells and to produce a connection with a load-bearing structure. Said crossmember profiles are not thick-walled rolled products, but consist of thin-walled metal sheets. In order to impart the necessary rigidity and the necessary section moduli to them, the webs of the profiles are designed to be hollow, but closed cross-sections being obtained nevertheless. As a result, considerable savings in terms of weight and costs can be achieved. At the same time, the crossmember profiles can be integrated into the interior architecture since their flanges can be easily designed such that the fastening points of the wall or roof shells are covered over.
