Abstract: 812,155. Tread-applying apparatus. DUNLOP RUBBER CO. Ltd. Oct. 18, 1956 [Nov. 1, 1955], No. 31143/55. Class 144 (1). A tread band 7, formed from a predetermined weight of extruded stock 1, is applied to a tyre carcass 8 on a drum or former 12 by being expanded into contact with a substantially non-distortable air-permeable lining 15 on the inner periphery of a cylinder 11 and retained thereagainst by a vacuum means 16, the cylinder 11 then being located coaxially around the carcass 8 and the vacuum released to permit contraction of the band 7 on to the cascass. As shown, the tread-band 7 is expanded by an annular air bag 10 carried on a cylinder 9 which is located within the cylinder 11 so that the tread peaks, at the junction of the concave tread surface 3 with the concave bevelled edges 4, 5 of the tread, seal against projections 14 on the inner periphery of the cylinder 11 and the surface 3 of the tread is engaged by the complementarily convex surface of the lining 15 between the projections 14. With the air bag 10 deflated and the cylinder 9 removed, the cylinder 11 is mounted around the drum 12 by means of axially-directed tubes 17 equi-spaced on the outer periphery of the cylinder 11 and slidably sleeved over corresponding rods 18 which extend from a baseplate 19 coaxially mounted on the drum spindle 21. Adjustable stops 22 on the rods 18 locate the cylinder 11 accurately around the carcass 8. Specification 786,162 is referred to.

Abstract: 804,441. Magnetic recording apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 1, 1955 [Nov. 1, 1954], No. 31172/55. Class 40 (2). A magnetic recording transducer mounting comprises a gas-stabilized head 12 positioned to urge a transducer 11 toward a movable magnetic record 10 and a spring means 17 to bias the head away from the record. As shown, the record 10 is a disc, and the head 12, which may be such as is disclosed in Specification 763,815 which is referred to, is drawn toward the disc by Bernoulli effect resulting from air supplied from a pump 14 via a hose 15 escaping from the head. Should the air pressure provided by the pump fall severely the piston 20 of a valve 16 is urged by its compression spring 21 to close two contacts 22 which complete a circuit from an electrical power supply 23 to an electromagnet 19 whose armature lifts a latch 18 to permit the torsion spring 17 to pivot an arm 13 carrying the head away from the disc 10 thereby preventing the transducer 11 from scraping or gouging the disc surface.

Abstract: 1,154,579. Thermoelectric materials. COMMISSARIAT A L'ENERGIE ATOMIQUE. 13 July, 1966 [13 July, 1965], No. 31551/66. Heading H1K. [Also in Division C7] Germanium-silicon alloys for use in thermoelectric conversion of energy are prepared by melting a mixture of Ge and Si powders together in this presence of a solvent metal at a temperature of not more than 1450 C., keeping the melt at this temperature for sufficient time to ensure homogenization and then cooling it to co-precipitate the Ge and Si and to allow crystals to grow followed by further cooling to ambient temperatures and separation of the crystals and solvent metal. Solvent metals mentioned are As, Sb, Ga, In, Bi, Sn, Pb, Tl, Ag, Au, Zn, Cd and Al. Traces of the solvent metal remaining in the alloy act as dopants and determine its conductivity type. The melting may be carried out under pressure if the solvent metal is too volatile. The solvent metal may be removed by vacuum or chemical treatment or by filtration of the solid crystals from the molten solvent metal. The final alloy may be heated to its solidus temperature in an atmosphere of SiCl 4  and GeCl 4  to obtain slugs of suitable size for thermoelectric use. The melting may preferably be carried out in a crucible of vitreous carbon, beryllia or zinc silicate.

Title: Improvements in devices for the automatic control of the speed or power of engines
IPC: G05D13/00
Filed: 1936-11-18
Abstract: 485,574. Regulating. PEARCE, A. W. Nov. 18, 1936, No. 31615. [Class 7 (vi)] [Also in Group XXXV] A throttle control device for an internalcombustion engine comprises a link in the actuating-mechanism which is altered in length when electric controls are actuated by a speedindicating instrument, either at maximum or minimum speed limits, to exercise a positive throttle closing or opening action overriding the setting imposed by an operator and limiting the effective travel of the mechanism at the upper or lower end of its range. One or more speed-indicating instruments may co-operate in the control in respect of the speed of the engine or of the propelling-members of a vehicle, or of the land, water, or air speed of the vehicle. A locking-device may maintain the normal condition of the link when limiting action is not required, and this may be released electromagnetically. A dashpot or other energy-absorbing device may be incorporated to prevent sudden speed changes. When the throttle is fully open, a release member such as a switch may be actuated to render the linkadjusting means inoperative. Figs. 3 and 7 show an element inserted at the points 2, 7 in a throttle member actuated longitudinally. The closure of contacts (not shown) by a speedsensitive indicator 20 energizes an electromagnet 17, whereby a latch 9 is disengaged and contacts 13 closed to energize an electromagnet 1. A plunger 4 is thus attracted against a spring 8, whereby the throttle link is shortened and the throttle 24 partly closed. The shortening may be effected pneumatically or hydraulically, as shown in Fig. 10, where the latch forms part of a valve slide 9a connecting cylinder 3a with atmosphere at 33 or with the induction manifold of the engine at 34. The pressure in the lubrication system of the engine or of a supercharger may be utilized.

Induction motor meters. - In an integrating meter of the induction type the damping is effected by alternating-current electromagnets and is automatically controlled so as to compensate the meter for frequency errors. Part of the damping flux is supplied by the pressure magnet 13, the strength of which is increased as described in Specification 274,134. The remainder of the damping flux is supplied by an electromagnet 22 connected across the mains through an adjustable condenser 23. The energizing circuit of the magnet 22 is tuned so as to operate on the ascending slope of the resonance curve over the variable frequency range, so that the damping due to the magnet 22 increase with increase of frequency, thereby compensating for the decrease of damping due to the pressure magnet 13. On a 60-cycle circuit the magnet 22 may supply about one-third of the total damping.
