Patent DE-3413074-A1 (DE)
Title: Method and device for generating an ultrasonic echo pattern by means of a linear array
Inventor: BIRK ADALBERT DIPL ING
IPC: G10K11/34
Filed: 1984-04-06
Abstract: The linear array (LA) contains a first and a second aperture (A1, A2). Both are activated with predetermined ultrasonic transmitting frequencies (f1, f2) at predetermined times. As a result, they radiate in each case a first and respectively second ultrasonic transmitting pulse (S1, S2) into the scanning plane. The two directions (a1, a2) of the transmitting pulses (S1, S2) differ from one another. The ultrasonic echoes received by the two apertures (A1, A2) after each ultrasonic transmitting pulse are converted into echo signals which are combined with one another in a geometrically correct manner in a combining circuit (V) to form pattern display signals. In this manner, a pattern is built up which contains information which is obtained by insonification from different directions (a1, a2). In this manner, round structures (R) such as, for example, vessels in the body of an organism can also be represented pictorially as a closed, round structure without loss of information. When different ultrasonic transmitting frequencies (f1, f2) are used, speckles can be largely avoided in the pattern. <IMAGE>

Patent DE-3434930-A1 (DE)
Title: Ophthalmic surgical instrument (capsulotome) for perforation of the crystalline capsule of the eye
Inventor: GEUDER VOLKER
IPC: A61F9/007
Filed: 1984-09-22
Abstract: The capsulotome comprises a control device and a handpiece having a needle guided so as to be longitudinally movable in a cannula which is driven at an adjustable puncturing frequency and can be operated between a puncturing position in which the needle tip projects from the cannula end remote from the handpiece and a restoring position in which the needle tip is retracted into the cannula. The needle is driven independently of the set puncturing frequency at an essentially constant puncturing speed which is dimensioned such that perforations are produced in the crystalline capsule of an eye to be operated on. In one embodiment, the needle is operated in the puncturing position counter to the action of a restoring spring, and an electromagnet is used as a drive means, the magnet switching from one terminal position to its other terminal position due to the action of pulses. The control device can be used to vary the cycle frequency of the pulse actions of the electromagnet and hence the puncturing frequency. The switching-over speed of the magnet and hence the puncturing speed are independent of the puncturing frequency.

Title: Cat transporting basket
Inventor: KUEPPER CHRISTEL
IPC: A01K1/01
Filed: 1984-10-26
Abstract: My CAT TRANSPORTING CASE has the external appearance of a conventional plastic case for cats and other small animals as well. As is explained below, my transport case is substantially different from all conventional types of basket in that my COMBI CAT can be converted by a single action into a travelling case which is almost twice as large. As a result of this, space is made in the main case housing for a cat toilet with some litter, and the said toilet can also be cleaned out from outside, at the front, in such a way that no animal can escape. Hazardous cleaning manoeuvres while on a journey are no longer necessary. Owner, animal and vehicle are no longer soiled, because in my COMBI CAT, the cat can leave its sleeping corner and pay a visit to the toilet inside the case at any time. Furthermore, the extended case can also render valuable service at home in the field of animal protection, by acting as a SICKNESS OR OBSERVATION BOX. The indispensable ROBUST SEPARATING SLIDE made of plastic or metal is used as an accessory for the extensible lattice box, so that veterinary surgeons and those involved in the protection of animals are able to help abandoned and especially feral cats without danger of injury. In the separated-off part, the animal can be made to inhale substances in a controlled manner, be irradiated and be sprayed to protect against vermin at least, without difficulty. My floating DRINKING BOWL (to be suspended on the lattice entrance door and lattice wall) consists of two hemispheres. The first hemisphere is stationary, while the second hemisphere is mm smaller and is situated ... Original abstract incomplete.

Title: Control circuit for a coolant compressor
Inventor: HEIDER ALEXANDER
IPC: F04B49/06
Filed: 1984-11-27
Abstract: A control circuit for the electric drive motor of a compressor incorporated in a coolant circuit of a cooling appliance is to assume control of the drive motor in a simple manner without interfering with the space to be cooled. To this end, the instantaneous power consumption of the motor is compared, in a switching device, with a given but variable setpoint and, when it falls below or exceeds the setpoint, the motor is switched off. The setpoint comprises a linkage of time-dependent operating sequences and exists in the form of, for example, setpoint curves 1 to 4 or as a constant-level setpoint line PSoll. <IMAGE>

Title: Mechanical actuating device for functionally correct fast running in an audio tape apparatus with reverse operation
Inventor: HAPKE WALTER
IPC: G11B15/44
Filed: 1985-12-17
Abstract: In an audio tape apparatus with reverse operation, in order to ensure that the fast-running buttons are always assigned the same function irrespective of the respective tape-running direction which can be set by a reverse slide, a switching cross which has two switching arms and is rotatably mounted at its crossing point is provided. Actuating the fast-running buttons induces a turning of the switching cross, which is transferred to a control slide for a switching gear mechanism. The control slide is connected by means of a follower to the one horizontal switching arm of the switching cross, the switching arm serving as a guide for the follower, which can be moved by the reverse slide along the switching arm. Consequently, in dependence on the two switching positions of the reverse slide, the control slide executes opposite control movements in response to the same turning movement of the switching cross, whereby the functionally correct assignment of the fast-running buttons is accomplished.
