Title: Iterative D:A converter - avoids unwanted output voltage rise from constant current sources when latter are switched to resistor network
Inventor: HOEFER ERNST
IPC: H03M1/00
Filed: 1975-12-23
Abstract: The iterative D/A converter is designed so that the constant current sources exhibit no unwanted rise in their output voltages when switched to and from the R-2R resistor network. Each of the constant current sources has a normally-closed short-circuiting switch assigned to it. Each of these switches only opens when a switch of one of the group of current supply switches assigned to the corresponding current source is closed, over which the corresponding constant current source can be connected to the R-2R resistor network.

Title: Seat belt tension cancelling mechanism - achieves web clamping by spring pressure and releasing by operating car body-fitted buckle
Inventor: WOLFF HANS-DIETRICH
IPC: B60R22/19
Filed: 1976-07-06
Abstract: The mechanism is fitted with encased springs (1, 2) acting on the clamping element (10) by intermediary of rods (6, 7) seated in swivelling hubs (4, 5). The clamping element is pulled upwards against the webbing and the bracket body (12). In order to cancel the closed condition of the bracket it has to be pulled upwards over the webbing until the cushioned part (3c) of the slide (3) touches the web deflecting buckle and further, until the slide (3) is moved completely upwards against the bracket body (12). In this position the springs (1, 2) and the springs fitted on the rods (6, 7) as well, are compressed to their max. When the pull on the webbing discontinues, the springs (6a, 7a) expand downwards and open up the clamping element (10) via stirrups (8, 9) and pins (10a, 10b). The clamping element is swung downwards. The expanding action of springs (1, 2) is retarded by an assembly consisting of slides (13a) fitted in slide head (3d) working in conjunction with a bakelite retarding wedge (13b, 13c).

Title: Control circuit for stepper motor drive - combines switching circuit and current regulator using transistors for both purposes and employing motor winding as choke
Inventor: BORGONOVI BRUNO ING GRAD
IPC: H02P8/12
Filed: 1976-07-31
Abstract: The circuit combines a bipolar end stage and an electronic current regulator into one unit. The motor field (LM) lies in a bridge diagonal with the current sensing resistor (S) in the supply. In one direction of rotation both appropriate transistors (T1, T7) are turned on. When the sensor and comparator (K) show that the current set level has been reached the positive side transistor (T1) turns off. The current free wheels through the other transistor T7) and a diode (D3). When the current again falls below the set value the process is repeated. The whole operation is under the control of a logic circuit which dictates which transistors shall conduct and at what frequency. It also determines the delay time necessary to allow for current decay in the windings when changing direction of rotation.

Title: Agitation of sample ampoules - having internal agitator with rotational drive from friction against stationary beam as ampoules are conveyed
IPC: G01N35/00
Filed: 1977-03-28
Abstract: Sample ampules have internal agitators to mix the liq. dispersion of the sample. They are held in a rack and conveyed along. The relative motion between the conveyor and a static bar mounted above it serves to induce a rotational motion in the agitators. The motion can be converted by friction drive or keyway. The agitator can have a wheel attached to the end which presses against a stationary beam past which the conveyor moves the ampules in their rack. The agitator shaft is mounted in the neck of the ampoule by means of a coverplate over the rack. This acts as a bearing and as the wheel rubs against the beam, the stirrer rotates, agitating the contents of the ampules. Esp. for agitating analytical samples. Various types of shaking devices are known which are noisy and require a lot of space. The system described allows the agitation to take place automatically, being combined with a conveying operation and not interfering with this.
