Title: Improvements relating to permanent magnets
IPC: H01F1/06
Filed: 1959-09-28
Abstract: A permanent magnet has as a constituent a phase which has been produced by a thermal treatment and which contains at least 60% Mn with the remainder substantially Al, the phase having a tetragonal crystal structure with an axes ratio c/a of >1 and <2. An example of this phase is that occurring in a binary Mn-Al alloy (Mn: Al atom ratio 5:4) and having the required structure with an axes ratio about 1.3 and an occupation of the lattice points 0, 0, 0 and 1/2 , \ba1/2 , \ba1/2 with a preference of the Mn atoms for one of these points. The Mn-Al alloy may be heat-treated to obtain the tetragonal phase by either (1) heating at a temperature below 1000 DEG C. for a sufficient time, or (2) cooling between 825 DEG and 600 DEG C. at a rate of 0.5-100 DEG C./second, or (3) cooling to below 825 DEG C. at a rate of more than 100 DEG C./second and then heating between 825 DEG and 600 DEG C. for a sufficient time. Homogenization before and annealing at 200-600 DEG C. after the phase-production heat treatment is beneficial. Particles for the production of the magnet may be produced by either (1) effecting solid state diffusion of powders of the constituent metals or pre-alloys thereof or (2) pulverizing a cast or sintered Mn-Al body with or without a prior heat treatment so that the brittle b phase is obtained. The particles are then heat-treated to produce the tetragonal phase. Alternatively the body may be pulverized after the phase-production heat treatment. The particles are formed into a magnet by compression with or without sintering they may be oriented in a magnetic field before or during compression. Specification 771,538 is referred to.

Title: Excitation system for generators
IPC: B21B35/14
Filed: 1967-02-15
Abstract: In a rolling mill coupling wherein a spindle 1 is universally connected to an externally splined block 3 and an internally splined sleeve 5 connects the block 3 to an externally splined hub 7 on a roll journal 9, a pneumatic or hydraulic servo (24), Fig. 4 (not shown), moves the sleeve 5 axially to disengage the coupling. A tongue 10 on the end of the spindle 1 lies between slippers 2 journalled within a cylindrical bore in the block 3. Springs 16 press a lubricant retaining sealing ring 12 into engagement with a flange 11 on the spindle 1 and urge the spindle into engagement with a thrust pad 17 on the block.

Title: Knitting machines
IPC: D04B15/78
Filed: 1967-11-11
Abstract: A pattern mechanism for a flat machine comprises an member displacable towards the ends of needle jacks and having means controlled at the distates of a pattern and held by electromagnets for selectively preventing their contact with the jacks. The displacable member 1 carries two rows 2, 3 of apertures oppositt needle jack 13. The apertures are selectively coverable by pivoted levers 5 actuated by electromagnets 9. Selected jacks are moved on displacement of member 1 by the surface 12 of levers covering selected apertures. The remaining jacks pass through the apertures. The levers may be locked in the positions shown. In the embodiment of Fig. 4 levers 21 pivotally mounted on member 27 are pivoted towards holding magnets 29 by cams 26 fixed to shafts 25. To prevent stray magnetic flux reaching the jacks the levers may include a non-magnetisable insert adjacent the jacks, or may be non-magnetisable with a magnetisable insert opposite the magnet. Alternatively the jacks may be non-magnetisable. The member 27 is of non-magnetic material. In a further modification the electromagnet influences a coupling connecting a drive to the members covering the apertures. To ensure the lever will fall away from the magnet when released it may be de-magnetised when held, by a pulse of opposite polarity or an alternating current of decreasing strength in the magnet, or a pulse applied to a second winding. The electromagnets may be controlled by perforated cords or film, or magnetic tape. The perforations required for each course may be arranged in several rows across one narrow cord.
