Title: Protective coating for carbon electrodes in electric furnaces - having high aluminium content and fixed with electric arc stabilized with magnetic field
IPC: H05B3/64
Filed: 1973-02-09
Abstract: Electric arc is formed between the carbon electrode to be coated and a side electrode, which moves along the carbon electrode whilst the latter is rotated so that the path of the ore on the surface of the carbon electrode is helical (and overlapping). The current is pref 1000-1250A. and the width of the path is 10-18 mm. Magnetic field is used in such a manner that the electric core is broadened, whereby its path is widened and, hence the coating process is accelerated.

Title: Pneumatic piston - with solid lubricated synthetic bearing and seals for long oil free use
IPC: F16J10/02
Filed: 1973-04-17
Abstract: The piston associated with anodised cylinder is split to incorporate a pair of wear seals of rubbery material filled with a solid lubricant (MoS2) and supported by an interventing hoop of a rigid plastic material to prevent the seals 'spreading'. The ram passes through twin outer seals also of lubricant filled rubber. Pref. the ram bearing comprises a mixture of PTFE and mica and is mounted in a cartridge holder readily released/inspected/replaced. Pref. the piston head carried compressible pads (rubber) on each end to damp the impact at the end of each stroke. For mfr. of pumps with long life maintenance - free duties without wet or mist lubrication, e.g. for food mfr. or medical applications. Rate of wear with elastic seals less against anodised Al than plain Al surfaces, allowing >=106 cycles continuous running. Coupling design allows for ram rotation w.r.t. the cylinder and its supply lines, to facilitate installation.

Title: Sample analysis support - having vessels which can rotate when installed in an analysing appts
IPC: G01N30/24
Filed: 1974-05-06
Abstract: A support made of a plastic material, e.g. polypropylene and moulded in a single part, comprises an assembly of small vessels for contg. the samples. The vessels are held at the ends of radial arms, which are all connected to a central disc that has a hole for mounting on an axial shaft, which enables the support to be periodically rotated a short distance. Each radial arm has an inner rigid section and an outer flexible section so that the vessels can be moved parallel to the central axis. The angle between each radial arm is equal except for between the first and last radial arm when it is more than the angle of constant value. The sample-carrying vessels all have upper parts which open out towards the top and lower parts which open out towards the bottom. A cylindrical ring, integral with the support, carries coded information in perforations on the ring concerning the sample in each vessel at the end of the radial arms. Used for carrying a number of samples to be analysed or treated, e.g. by gas chromatography. The support can be easily and rapidly installed in the analysing appts., and can be used for taking and stocking samples over a period of time. It can be easily mass produced by moulding.

Title: Pre-paid access system - is able to perform credit cancellation of access ticket during use via magnet transducer heads
IPC: G07B15/02
Filed: 1975-04-24
