Title: Mould for continuous casting copper billets - where water flows from base of mould onto the cast billet
Inventor: DOMPAS JOHN
IPC: B22D11/049
Filed: 1974-11-15
Abstract: The mould is provided with a cooling jacket with side inlets for a coolant (e.g. water) flowing between the mould wall and the jacket and leaving the mould via a cone at the base of the mould so the water flows onto the billet as the latter leaves the mould. An additional wall is located in the cooling jacket and fitted with ribs so that many channels are formed and the water is forced to travel upwards, through the ribs, forming laminar flow and then travelling out via the cone. The ribs pref. exceed 17 in number, with height 10-60 mm and even distribution round the additional wall. Two diametrically opposed water inlets are pref. used and the cross-section area of the outlet cone is pref. less than 0.9 times the total inlet cross-section area. Simple construction with uniform distribution of the coolant and thus uniform cooling of the billet.

Title: Transformer tap changing switch selector contacts - are fixed to hard laminated paper bars by cotter pins and retainers
Inventor: WIDMANN WERNER
IPC: H01F29/02
Filed: 1975-02-14
Abstract: The contacts of selectors on tap changing switches of transformers can be attached to the hard paper bars (2) so that higher temperatures during the necessary drying operation cause no slackening of the contacts and that the paper shrinkage is fully compensated. The contact (1) is held by a cotter pin (3) which passes through the paper bar (2) at right angles to the laminations. Another bearing face (4) prevents any displacement around the pin centre line. A retainer (5) is pressed into a recess of the contact (1), and over the pin end. The threaded bore (6) is used to connect the leads from the contact to the tapping of the transformer winding. Other versions surround the bar additionally at rear or use wedges for additional fixing.

Title: Rotating magnetic key for vehicle cylinder lock - has split screened magnets for preventing interaction generating directed magnetic fields
Inventor: HEIMANN GEORG DR
IPC: E05B47/00
Filed: 1975-09-06
Abstract: The magnets inserted into the key each consist of two part magnets. Between each magnet is placed a screening layer (3) made of ferromagnetic material. This screens the field of individual magnets from each other and prevents a displacement of the magnetic fields by interaction of the magnets. The component magnets can be made from an isotropic material. In this case the screening layer is used as conducting layer for magnetic force lines. Magnetic fields of each magnet emerge at right angles to the magnet surface and are directed to the magnets of the associated lock tumblers. The magnetic system is accurately matched to the given key circuit, and no angular shift of magnetic field occurs due to interaction of the magnets.

Title: Magneto:optical current measurement transducer - uses polarisation plane rotation to avoid shape birefringence from angled photoconductor coil
Inventor: FELDTKELLER ERNST DR
IPC: G02F1/09
Filed: 1975-10-28
Abstract: A magneto-optical current converter for measurement of currents uses a photo-conductive coil of fibres surrounding a current conductor carrying the current to be measured. It is developed to compensate for shape double refraction or birefringence. The device is constructed without inbuilt mechanical stress as in 2445369 to eliminate stress birefringence. A linear polarised light ray is passed through the fibre coil and its polarisation plane is rotated by the magnetic field of the current in the conductor (10) to give a measure of the current. The degree of rotation may be affected by birefringence due to the coil shape. The coil is constructed with a helix angle greater than thirty degrees.
