Patent DE-2724077-A1 (DE)
Inventor: SCHIMMER ADOLF ING GRAD
IPC: H04Q3/545
Filed: 1977-05-27
Abstract: In order to reduce memory costs in the program memory and/or in the assigned subprogram memory, a parameter memory (PS7) is assigned as a read-only memory to every change of state (H) resulting from every state (PS5) and every switching procedure or stimulus. All these parameter memories (PS5, PS6, PS7) have the same range of information. The performance of a switching procedure in the event of a change of state takes place with the aid of the parameter memory (PS7) and thus the commands for functional steps performed by the central controller with the aid of a program memory, and every performance of all commands for functional steps which are present in the parameter memory (PS7) again lead to a new state, i.e. new parameter memory (PS8, PS17, PS19), or to the cleardown or forwarding of the connection. <IMAGE>

Title: Bottle handling grab mechanism - has sliding cylinders closing sockets moving down against sides of bottles
Inventor: RUDOLPH HANS
IPC: B65B21/12
Filed: 1977-06-15
Abstract: The grab mechanism handles bottles and similar items, having grip sockets on bolts fitted over the items from above and widening towards the bottom when open. On fitting over the items cylinders slide over the sockets, compressing them in the radial direction. The axial closing movement of cylinder (8) and/or socket (7) is continued after closing of the socket until the lower cylinder edge bears against the bottle. This prevents the bottles swinging in the sockets when lifted, so that they can be handled more rapidly during packing and other operations. There can be protruding ribs on the inside of each cylinder where it moves over the socket.
Patent DE-2728270-A1 (DE)
Inventor: BUZZARD CLAIR ALAN
IPC: G06F11/00
Filed: 1977-06-23
Abstract: A memory array, having a plurality of intersecting rows and columns, stores digitized speech. Each row and column intersection consists of a binary storage cell for storing one bit of digitized speech. Incoming digitized speech is loaded into columns of the memory array in a plurality of repetitive loading sequences, each loading sequence including: reading out the bits stored in successive rows of binary storage cells, replacing in each successive row of bits, a predetermined one of the bits in the read out row with a successive one of the bits of the digitized speech and writing each read out row of bits including the replaced bit back into the row. Multibit binary grunts (digitized speech segments) stored in the array are read out therefrom by applying the bits of the grunts to time slots in frames on a time-division highway, each frame being of n bits duration and including one bit from each of n grunts stored in the array. A selected grunt is extracted from the highway by commencing a count of the bits on the highway with a first bit of the selected grunt and by extracting the first bit and every nth bit thereafter. Memory malfunction is indicated when the number of rows in the array containing parity errors exceeds a predetermined threshold number.

Title: Variable frequency solid state controller for AC motor - gives constant motor flux at all speeds using RL circuit controlled by given parameters
Inventor: BLOECHER CHRISTIAN ING GRAD
IPC: H02P21/00
Filed: 1978-02-16
Abstract: The object is to give constant motor flux at all speeds thus improving the utilisation of the machine. It is achieved by a controller simpler than previously in use. The basic approximation used for the regulator is:- U1X = square root 3.Uh + square root 3.R1.I1.cos phi1. Where Uh - is the required voltage for magnetising, and frequency dependant, and R1 - is the stator winding ohmic resistance, and I1 - is the fundamental frequency motor current, and U1X - is the motor terminal voltage and cos phi1 - is the motor power factor. Uh is in effect the reference voltage and U1X is the controlled voltage. The equation can readily be simulated by a simple operational amplifier circuit. The error introduced by the approximation can be shown to be less than 4% at rated torque and at a low frequency of 2Hz.

Title: Controlled modification of printed circuits - using cutter for removing conductor material and solder tip for connecting new wire
Inventor: WARMUTH JOHANN
IPC: H05K3/22
Filed: 1979-06-22
Abstract: The equipment is used when finished printed circuit cards have to be modified but time does not permit the design and mfr. of a new one, e.g. when circuit changes are found necessary during tests on a complete installation. The equipment eliminates hand work on circuit cards and thus reduces the risk of accidental incorrect cuts or damage to other circuit components. A work bench has a circuit mounting base with coordinate adjustment for exact positioning of the card under a fixed milling head. With the card in the correct position the miller, which has automatic depth control, is brought down manually to make the required cut. A soldering head is similarly in a fixed mounting. It is manually actuated to solder the new wire or connection into position with a preset pressure and time cycle. There is no solder feed and thus no risk of any surplus metal causing short circuits. Numerical controls can be added to the coordinate table for automatic positioning of the circuit card.
