Title: Directional relay for unearthed networks - has control for reference voltage generating binary test signal and directional memory at output
Inventor: RAGETH PAUL DIPL ING
IPC: H02H1/00
Filed: 1975-03-13
Abstract: The directional relay is intended for short interruption and receives a switching command signal in the form of an overcurrent and reference voltage combination for generating a non-directional overcurrent signal, together with an overcurrent signal indicating the network fault in front or behind the relay. The relay has a control device used for transmitting a binary test signal for the reference voltage. The output for the directional overcurrent signals contains a directional memory which incorporates a switching command signal store and a logic circuit, controlled by the test signal, for storing a switching command signal in case of reliable reference voltage for a preset time period. This circuit reads out the stored switching command signal in case of an unreliable reference voltage.

Title: Conveyor for moving articles to a packaging station - downwards from rotating brush and reciprocating grippers, then forwards between rotating discs
Inventor: SLACH JAROMIR
IPC: B65G47/88
Filed: 1975-03-18
Abstract: A conveyor for feeding e.g. cigarette packets to a packaging and 'cellophane' (RTM) wrapping station has a horizontal overhead trough conveyor with a bend terminating in a vertical portion. The packets travel past a brush rotating about a horizontal shaft, while a gripper block each side guides their downwards movement. Each gripper is rotated by an attached roller mounted on a common spindle, rotated in turn by eccentric wheels at right angles, mounted on the brush drive shaft. They are thus conveyed further downwards onto two horizontal rotating discs driven from underneath, and carrying raised segments around their edge with vertical pins in the gaps between. These advance the packets to a take-off conveyor. The rollers actuated by the eccentrics are retained by springs.

Title: Semiconductor matrix of photoemitter elements prodn. - by ion implantation of zinc in gallium arsenide structure and diffusion tempering
Inventor: AKIMOW JURY STEPANOWITSCH
IPC: H01L27/15
Filed: 1975-06-18
Abstract: In the prodn. of a semiconductor matrix of photoemitter elements based on an epitaxial structure of a p+ - GaAs substrate with cons4cutive p-Ga1-xAlxAs- and n-Ga1-yAly-As- layers forming a photoemitting pn-junction, by producing a mask in the n-layer, introducing an acceptor through the former into the n-layer and diffusion tempering for a time and at a temp. sufficient to produce p-zones in the n layer having an penetration depth at least equal to the thickness of the n-layer, the mask is produced by applying a photoresist coating to the n-layer, followed by exposure and etching, and the acceptor is introduced by ion implantation and, before diffusion tempering, the photoresist coating is removed and a SiO2 coating is applied to the n-layer. The process extends the useful range of the matrix and is also more economical. It is not necessary to use a dielectric Al2O3 coating, introduction of Zn and diffusion tempering in an ampoule. Photoemitter elements with linear dimensions of under 70-100 mu m can be produced.

Title: Crystallisation from solvents more volatile than water - e.g. dimethyl-terephthalate from soln. in methanol
Inventor: BENNETT RICHARD CHISHOLM
IPC: B01D9/00
Filed: 1975-10-31
Abstract: In a plant for crystallisation of dissolved material from a solvent substantially more volatile than water at a temp. substantially higher than the b.pt. at atmos. press., crystallisation is achieved by cooling of the soln. The plant includes a vessel contg. the crystallisation system having a normal effective lever, with an outlet for crystal slurry, an inlet for a mixed stream at the normal effective level, a pump and pipework for recirculation from outlet to inlet at high velocity, a cooler for the vapour and/or the recirculation flow, a bleed-off for crystal slurry out of the recirculation system or vessel and a means of introducing an additional (feed) stream into the recirculating stream. In order to prevent an excessive formation of fine crystals, the hydrostatic press. of the recirculation stream at the pt. at which it is mixed with the additional stream at the recirculation pump is maintained at a level equal to or greater in the recirculation flow and that in the additional stream prevailing at the mixing point. Minimisation of small crystal formation permits optimum sepn. of crystals from slurry.

Title: Heavy single phase starting circuit - is for polyphase motors regulated by cam switch in combination of Ott's and Steinmetz circuits
Inventor: KEMMERICH KARL-HEINZ
IPC: H02P1/16
Filed: 1976-06-24
Abstract: The special circuit for heavy starting loads in case of a single-phase operation of a polyphase motor, is based on a combination of characteristics of the Ott's and Steinmetz' circuits. This lead to a high pick-1p torque. The normal manual switch or pole changing switch can be employed with slight modification, with the former linked to a protective contactor due to high amperage maintained through long periods of time. In the case of a pole-changing switch or a star-triangle switch, the star bridge connections are removed. The combination allows one to use smaller capacitors since the circuit of Ott provides a double winding for the auxiliary coil as a transformer for voltage rising.

Abstract: The synchronous machine is supplied from an invertor. Nominal current values for a phase current controller are generated in a stator current nominal value generator. Stator flux indicator is oriented along the field by two independently variable components, of which one is always perpendicular, and the other always parallel to the rotating field axis. Two orthogonal field components related to the stator, determining the instantaneous position of the rotating field axis, convert the field oriented nominal value components into two stator related nominal value components which are applied to the stator current value generator. Nominal value component (Iwcurrent component generating the torque, is limited to a value at the most corresponding to the machine instantaneous excitation current value.

Title: Automatic echo recognition and coordinate determination - employs all-round target detection and tracking system and has all-round rangefinder
Inventor: SCHEER KURT DIPL ING
IPC: G01S7/292
Filed: 1976-10-05
Abstract: Binary integration for target extraction is carried out on the moving window and/or pulse pattern principle simultaneously. Echo recognition and decoding is carried a in real time by n-from-m correlation by means of integration tables implemented in read-only memories or in programmed logical arrays. After quantisation, the video signal is carried to the moving window memory by the provision of a first threshold whose height is adjusted selectively by the passage of a noise detector. The range and azimuth are decoded and evaluated by selectively adjustable correlation. The moving window memory can be made from semiconductor elements with random access.
