Title: Multichannel feed for single beam measurement oscillograph - has low level multiplexer followed by stepped voltage addition to raise signals to display level
Inventor: SCHMID ANTON DIPL ING
IPC: G01R15/09
Filed: 1977-07-01
Abstract: The operational method is for multichannel measuring equipment, esp. one with a single beam oscillograph and a multiway input switch in which the various measurement signal sources are connected to the inputs of a multiplexer and passed on to the oscillograph in sequence under the control of a clock signal.

Title: Spinning method - using air currents to direct fibres into a yarn-forming zone between revolving cylinders
Inventor: LENK ERICH DR ING
IPC: D01H4/16
Filed: 1977-07-20
Abstract: The spinning appts. comprises a delivery device where a ribbon or tow of fibres is introduced through the entry orifice. The ribbon or tow is drawn in by the feed roller and broken or sepd. into fibres by the toothed cylinder. The fibres are collected in the flow channel in an opened, parallel arrangement by an air flow. Flying freely, they descent to the line of fibre formation where they are twisted into yarn by contact with the cylinders, and the action of the air flows passing through the cylinder walls. By a gradation of pressure of the air on the appts., an improved air flow is provided by which the individual fibres formed from the ribbon or tow are directed at high speed for collection uniformly at the yarn formation line, which is the gap between the two cylinders.

The comparator also supplies signals through an OR gate and NOT gate to another relay (R) which operates the change-over switch.
Patent DE-2749226-A1 (DE)
Inventor: HOERDER ALEXANDER DIPL ING
IPC: G06F15/167
Filed: 1977-11-03
Abstract: A data exchange control in full-duplex mode is proposed for two microcomputers (MR1, MR2) which in each case essentially consist of a microprocessor (CPU1, CPU2) controlled by a clock generator (TG1, TG2). The data bus is connected to a system memory (SSR1, SSR2) for programs and data and input and output units which are activated by addresses conducted via an address bus and separate control signals. For this purpose, each microcomputer is equipped with a FIFO (first-in-first-out) memory which, with the aid of program-controlled signals, allows the required data exchange during a data transmission between the two microcomputers in the transparent mode in block traffic to be decoupled in time. The transmitted data words are not themselves used for controlling the transmission. <IMAGE>

Title: Open-mouthed cans feeding method - includes synchronising movement of cans, supported on conveyor, with rotational speed of turret for transferring cans into turret
Inventor: JACKSON JOHN MAXWELL
IPC: B65G47/84
Filed: 1978-04-24
Abstract: The method is of feeding open-mouthed cylindrical cans of a predetermined size onto a turret having a number of can holding units for reception of cans fed to it in a direction parallel to the rotational axis of the turret. The method compises supporting the cans by suction on locating surfaces on a conveyor and continuously driving the conveyor so as to move the cans transversely to the axes along a path passing through a transfer station. The latter is arranged so that a can can be transferred into a holding unit in the loading station by axial movement of the can. Axial movement is imparted to each can in the direction towards the loading station upon register of the can in the transfer station. Movement of the cans along the path is synchronised in accordance with the rotational speed of the turret so that one of the can holding units one turret is in register with the loading station for receptions of each can fed to it from the transfer station.

IPC: B01D9/00
Filed: 1978-05-18
Abstract: A method of lining a hollow object (e.g. of silicone rubber) with synthetic crystals by lowering the temp. of aq. salt solutions is as follows. The object is filled to the desired level of the lining with an aq. soln. of >=1 salt having a concn. which is above the seed crystal-forming limit at a predetermined temp.; the temp. is then lowered to reduce the salt concn. at a temp. not higher than the final temp. of the first soln. but having a lower salt concn. The concn. of this salt soln. is then lowered by further reducing the temp. Pref. the second salt soln. has the same composition as the first. The starting temp. of the second soln. may be lower than the final temp. of the first. Used esp. for the prodn. of ornamental hollow objects, in which the internal crystal lining produces optical effects. An example of the mfr. of paperweights. The method enables a uniform reflective crystal lining to be obtd. in a simple manner in a single process without trial crystallisation and subsequent rejection of unsuitable results.
