A magnetic marker for use with electronic article surveillance systems in which a very high order harmonic response is obtained with postage-stamp sized pieces of high permeability material shaped to have a narrow switching section within which flux is concentrated by larger sections on each end of the switching section, the concentrated flux being sufficient to result in a high harmonic response.

A dual status magnetic marker for use in electronic article surveillance systems, in which a piece of low coercive force, high permeability material is positioned adjacent to a piece of remanently magnetizable material. The first piece is configured such that no characteristic response is produced when the magnetization of the entire piece is reversed by an alternating magnetic field in an interro...

One of the executing instructions entered into the CPU includes two words. One word includes an operation code field for identifying the instructions as one which the CPU will execute, and an escape code field for identifying a class of instruction including extended integer instructions and commercial instruction processor instructions. The second word includes a data type field for identifying...

The apparatus performs a shifting operat-on operand signals and is characterised by; a control store responsive to said instruction signals and generating corresponding control signals; shift distance control and also logic systems responsive to the shift control signals for generating the shift signals indicative of the number of bit positions which the operand signals are shifted during the oper...

The CMOS circuit comprises a first dynamic inverter and a second inverter which may be static, dynamic, or selectably static or dynamic, with a clamping device connected to the output of the first inverter. The information processor portion of a microcomputer has an instruction register, a multiplexer, a micro instruction address register, a ROM storing micro instruction, a control register, an a...

The record-layer has a pck-up transducer which is movable tangentially by a transducer to correct for errors in the relative velocity between the transducer and the record, the transducer being part of a velocity correction servo which is responsive to a first signal component reproduced from the disc indicative of the relative velocity. For a video disc player that first component is the burst c...

The detection system has a light detector having 4 light receiving regions arranged in a far field of an information track. The regions are divided about an optical axis of an incident light beam in orthogonal directions. Output signals are obtained from the diagonally aligned regions and supplied to a first adder to produce a sum. Two other signals are supplied to a second adder from the other ...

A process for the maintenance of chain-type bottle conveyor belts in beverage-filling plants, more particularly in breweries, wherein the chain-type bottle conveyor belts are lubricated with belt lubricating agents with a base of neutralized primary fatty amines and are cleaned with cationic cleaning agents or organic acids. The invention enables a smooth, continuous bottle conveyance operation.

Structure is produced by firing a multilayered structure in which patterns of copper based paste and ceramic layers are laminated alternately. The ceramic layers are glass ceramic green sheets contg. a thermally depolymerisable resin binder. Firing is conducted in two stages, the first being in an inert atmosphere contg. water vapour at a partial pressure of 0.005-0.3 atm. at a temp. at which th...

The formation of fibrous wadding, e.g. of mineral fibres is effected by a gas stream which carries the fibres on to a conveyor belt. Part of the gas current is drawn off by suction from the periphery of its flow. The arrangement provides control of thermal conditions for the fibres, and alters the compression of the wadding by reducing the piling of fibres on to the wadding layer.

The transport of e.g. mineral fibres by gas streams effects the deposition of the fibres on a conveyor belt. The distribution of the gas stream carring the fibres is improved by enveloping the stream in a gaseous layer whose direction of flow in a taugential plane is not the same as that of the gas stream. The gaseous leyer widens out the fibre-bearing stream. The method improves the distributi...

The invention relates to a solid stud or hollow stud arranged in the tyre of a vehicle. The solid stud or hollow stud 20 is configured in such a way that when the stud is in a state of rest, the region A which is in contact with its rubber 14 is substantially smaller than the total area of the corresponding region in the stud, the flow of rubber 14 around the solid stud or hollow stud 20, which fl...
