Title: Massecuite crystalliser column - with alternately inverted conical deck plates and cooled paddle mixer
Inventor: MATUSCH SIEGFRIED ING GRAD
IPC: C13B30/02
Filed: 1978-05-13
Abstract: A crystalliser column for massecuite in the sugar industry has several decks of conical plates, with every other cone inverted. Each apex of an inverted cone forms with a vertical paddle mixer shaft, and the outward edge of each normal cone forms with the column wall the annular slots for the massecuite passage. The paddles are hollow and receive, together with their shaft, a coolant in counter flow to the massecuite. This creates a clearly defined passageway for the massecuite so that the heat transmission is improved and a high throughput is achieved without excessive input for the paddle mixer.

Title: Audio frequency transmission system - connects loudspeakers to radio receiver and tape recorder and has two interconnected audio channels
Inventor: DURST KLAUS DIPL ING
IPC: H03H11/04
Filed: 1978-12-23
Abstract: The transmission system has two voltage dividers (RI/R3 and RII/R3) connected between earth and the outputs of the input amplifiers in each audio channel. The shared tapping of the dividers can be earthed via a controlled impedance (20) and is also connected via a band-pass filter (15) and rectifier (16) to the control inputs of the low pass filters at the outputs of the two audio channels. An integrator (21) is connected to the output of the rectifier and produces the control signals for the controlled impedance. The advantage lies in the attenuation experienced by the audio signals being almost independent of the source of those signals.

Title: Mask positioning system for semiconductor manufacture - uses symbols on each layer supplying positional information for computerised control system
Inventor: HAHN KURT DIPL ING
IPC: H01L21/66
Filed: 1979-06-13
Abstract: The method of checking the positions of a set of masks used in integrated circuit manufacture uses a special identifying symbol for each mask. The structure of each mask is formed so that the symbol projects at a given point different from the others, which identify different components on each mask layer. When the layers are superimposed, the location of the symbols ensures that the conductors on each layer line up with the conductors on other layers at required positions. The individual stages of alignment are carried out by a computer system, and the symbols are used to provide positional information which is fed into the computer.

Title: Fast computation of direction finder angle tangent - repeatedly adding and shifting two components to generate binary fraction
Inventor: SAUR HERMANN ING GRAD
IPC: G01S3/30
Filed: 1979-06-26
Abstract: In a direction finder system, the amplitudes of the X and Y signals are converted to binary numbers. The ratio of the smaller to the larger is computed as a 10-place binary fraction, i.e., the tangent of the direction finder angle in an octant. The numbers are read serially into two 10-place stores, (2,3), the larger into (2), the smaller into (3), until a '1' appears in the most significant bit of (2). Both numbers are then added repeatedly to the lowest 10 places of two 20-place stores, (4,5) i.e., (2) into (4), (3) into (5). Whenever a carry occurs from the 11th to the 10thplace of store (4), both stores are shifted up one place before the next addition. The cycle stops when the top 10 places of one store (4) are all unity. The top 10 places of another store (5) is then the required binary fraction. The process works by multiplying both numbers by the same amount to make the larger equal to 1023.

Title: Sewing machine spool winder - has thread guide assembly in a compact unit near spool winder
Inventor: PAPAJEWSKI REINHOLD
IPC: D05B59/00
Filed: 1979-08-01
Abstract: The thread guide, for spool winding, is so mounted in relation to the winding mechanism that the thread guide opening lies in a plane which is vertical to the axis of the spindle at an intermediate point along its length. There are a number of spaced guides to deflect the thread path, each having an upper surface on a friction arm. The arm is straight and parallel to the spindle axis, and is long enough to be at least the length of the spool carrier. The thread path starts at the guide opening and then passes in succession round the guides to end at the spindle. The length of the thread path is in a specific relationship to the spool carrier length of the spindle and the gap between the guide opening and the spindle equals or is less than the gap between any guide unit and the spindle. The design gives a very compact spool winding mechanism on the sewing machine.

Title: High or medium voltage switchgear cabinet - has line of weakness along top sheet for forming tongues bent outwards by arcing gas pressure
Inventor: HOYER PETER DR
IPC: H02B13/025
Filed: 1979-12-21
Abstract: High or medium voltage switchgear cabinets are fitted with top sheets, each of which has a weak zone so that it is easily forced open in the event of arcing which would cause damage if confirmed. This weakness can be formed by a zig-zag or meander shaped line formed by stamping or by perforations. The shape ensures that alternative sections are swung upwards about hinge points on opposite sides of the top surface. In an alternative, the breakage line can be curved, with large loops spaced a certain distance away from one edge, and narrower necked parts closer to the other edge. The necked end remains intact, while the loop of each section is forced upwards. In another design, with a zig-zag line, parts of the edges overlap.
