Inventor: BUEHLER KNUT
IPC: H02B1/052
Filed: 1980-04-30
Abstract: The method of assembly does not require screws or similar clamps for covering the ends of an assembly of switches (14) on a support rail.

Patent DE-3028947-A1 (DE)
Inventor: BARTHOLDTSEN DIETER ING GRAD
IPC: B29C43/58
Filed: 1980-07-30
Abstract: A method for manufacturing high information density storage disks, suitable for optical reading, out of transparent synthetics having a high glass temperature and high dimensional stability. The present injection molding method avoids potential double diffraction disruptive effects created by frictional or shearing forces. The synthetic material which is to be pressed is injected into one of the mold halves at a temperature that significantly exceeds the pressing temperature of the compression form and is injected so as to form a lump of the material. The pressing step wherein the compression form is closed down to a squeezing gap width is initiated prior to the termination of the injection operation. Likewise the cooling operation is initiated prior to the termination of the pressing step and both the cooling and pressing operations chronologically proceed at approximately an exponential rate.

Title: LV push-pull switch for hand or foot usage - has spring assisted operation and magnet or catch release for pull and hold position
Inventor: SCHLEYER MEINOLF ING GRAD
IPC: H01H3/02
Filed: 1980-11-15
Abstract: Positive action from one switch state to the other is achieved without the possibility of the operating action causing a double-operation of the switching mechanism resulting in an unintentional fall back to the first state. The switch may have a magnetic click stop assist or be purely mechanical. The magnetic version has a central column (1) with a defined operative distance (I,O) located above the switch (20) plunger (21). The column (1) is held in position by a compression spring (4) between collars (15,5) at one end and a permanent magnet (10) stopped against a switch housing shoulder (11,17) at the other. To operate, the knob (2) is pressed and the magnet (10) and the column (1) are moved together so that the magnet (10) is released from its pole piece (11). The spring (4) takes over to pull the column down onto the switch plunger (21) and hold it in position. To switch off the knob (2) is pulled and the magnet (10) returned to hold against its pole piece (11).

Title: Circuit arrangement for extending telephone PABX systems
Inventor: SCHNABEL HARALD DIPL ING
IPC: H04M7/14
Filed: 1981-03-20
Abstract: The circuit arrangement for extending telephone PABX systems essentially comprises a higher-order, matrix-shaped switching network (KFÜ) with full availability, to which a plurality of sub-systems (TA) can be connected.

Title: Polarization haploscope
Inventor: ECKERT GEORG DR MED
IPC: A61B3/08
Filed: 1981-03-25
Abstract: The polarization haploscope is a universal device which permits binocular functions to be demonstrated and quantified, and special training of binocular vision to be carried out. It will primarily be used for patients with squint. Determination of the central visual acuity is possible as are aniseikonia determinations, i.e. differences in image size can be recorded for each eye. Use of the so-called Haiding's brush in free space expands the diagnostic possibilities. In addition, amblyopia can be accurately recorded and classified. Furthermore, accurate recording and follow-up of paralytic strabismus is possible. It is to be emphasized, in particular, that the natural conditions of vision, i.e. the conditions in free space, can be perfectly simulated and that work can be carried out virtually without any dissociation.
Patent DE-3114007-A1 (DE)
Title: Reversing circuit
Inventor: BUCKSCH WALTER
IPC: H02P7/03
Filed: 1981-04-07
Abstract: The invention relates to the field of reversing drive motors, relating especially to a reversing circuit for a drive motor, which reversing circuit is supplied with a supply voltage (one polarity) which is derived from an operating voltage (which can be varied in order to control the rotation speed) of the drive motor and is supplied to an input terminal. In order to allow the drive motor to rotate optionally in one direction or the other, a switching device is proposed which is always in one of two stable setting positions which each define one rotation direction of the drive motor. In these setting positions, it applies the operating voltage to the drive motor in each case such that it rotates in the desired direction. This switching device can be switched over into its other stable setting position in each case by means of a switching pulse which is superimposed on the operating voltage. The switching device contains a non-volatile read-only memory element (30) in which information characterising one rotation direction of the drive motor (1) is stored. In addition, it contains a bistable, electronic switching element (16) which can in each case be changed into its other switching state by the switching pulse and whose respective switching state defines the rotation direction of the drive motor (1). The switching element (16) can be switched over into the switching state corresponding to the information contained in the read-only memory element (30), by means of a setting device. A switch changeover device (12) causes the switching element (16) to change over into its other respective switching state, and a transmission device (31, 62, 65, 72) is used to transmit to the read-only memory element (30) the rotation-direction information which is represented by the respective switching state of the switching element (16). The invention can be used for reversing the drive motor used in a toy locomotive. <IMAGE>

Title: Method of conveying pallets and skeleton containers which rest on pallets or trucks
Inventor: BINNENBRUCK WERNER
IPC: B62B3/065
Filed: 1981-05-26
Abstract: The proposed method enables pallets - even pallets with bottom boards - to be conveyed in the low-lift range and in the adjoining stacking range with the use of a novel conveying means, a fork-lift truck with two lifting devices placed one above the other (Fig. 1/1/2/3/4/5/6). The bottom lifting device, which is that of a conventional fork-lift truck, serves to convey the pallets in the low-lift range, and the top lifting device serves to convey the pallets in the adjoining stacking range. The method permits for the first time especially manoeuvrable conveying of corresponding auxiliary conveying means in both ranges. <IMAGE>

Title: Structural body with net-like chamber system of self-hardening casting compound, such as, for example, concrete, and method of producing it
Inventor: KOZENY ERIK DR
IPC: E01F8/02
Filed: 1981-07-17
Abstract: The invention relates to a structural body as well as a method of producing it, which enables natural plant growth to be achieved even on perpendicular concrete surfaces such as, for example, retaining or noise-protection walls. For this purpose, a net-like chamber system open to the top for watering, filled with a nutrient substrate and partly open to the visible plane (planting or growing holes) is produced under the (perpendicular) surface by means of "permanent formwork" consisting of reinforced nutrient substrate and integrally cast in the concrete. Already existing (concrete) walls can be made suitable for plant vegetation by half-shell-shaped structural bodies which are broken in two and are filled with nutrient substrate and the open rear side of which is thus closed off by the existing wall. The invention not only permits novel designs in garden and landscape architecture but in particular also enables technological structures of large area, such as, for instance, retaining and noise-protection walls, to be integrated in nature in an environmentally friendly manner.
