Title: Improvements in electrical circuit control devices
IPC: H01H51/08
Filed: 1933-11-21
Abstract: 432,100. Electromagnetic switches and contact-making relays. WESTERN ELECTRICAL INSTRUMENT CORPORATION, 614, Frelinghuysen Avenue, Newark, New Jersey, U.S.A.-(Assignees of Lamb, A. H.) Nov. 21, 1933, No. 32422. Convention date, Sept. 8. [Class 38 (v)] In an electric circuit control device the pointer of an instrument sensitive to variations in a characteristic has a magnetic rider or armature displaceable into the range of a magnet, the rider and magnet also forming contacts to complete a controlled circuit, contact-separating means being provided to force said contacts apart in opposition to the magnetic attraction of said rider and magnet. As shown in Fig. 1 the moving coil 1 of an instrument which may be supplied by currents from a thermo-couple in an electric furnace carries a pointer 2 bearing contacts, a magnetic armature 3 which also acts as a movable contact. Pivoted below the pointer is a permanent magnet 5 the ends of which also act as contacts and which, with the armature 3 may be plated with gold or silver to form contacting surfaces. As the pointer moves towards the left owing to decrease in the furnace temperature the armature comes within the range of attraction of the left-hand pole of the magnet 5 causing a final rapid movement of the pointer to engage contacts. This completes the circuit of a stepping magnet 13 which moves around a cam disc 9. The movement of the cam disc swings over the magnet 5 to the dotted position. The instrument pointer is prevented from following the movement of the magnet by means of a non-magnetic stop 4 so that contact between the armature and magnet is broken, the former being removed from the range of attraction of the latter. At the same time the circuit of magnet 13 is broken. The movement of the cam disc also closes contacts 18 in the heater control circuit of the furnace which on heating up causes a movement of the instrument pointer to the right hand. On the maximum predetermined temperature being reached the armature 3 is drawn to the right-hand pole of the magnet 5 and a similar sequence of operations occurs which restores the parts to the position shown. Various modified arrangements are also described. In Fig. 2 the armature 3 is attracted by a fixed magnetic contact 5<a> on approaching its left-hand position. After contacting a circuit is completed through a heating coil 20 of a bimetallic strip 19 which on bending moves the pointer to the right removing the armature from the influence of the magnetic contact 5<a>. In other forms the pointer may be moved from a magnetic contact by an electromagnet under manual or automatic control or by means of a constantly-rotating clockwork-actuated arm. The instrument may, alternatively, be sensitive to variations in factors other than heat, for example, light, humidity &c.

Abstract: 1272352 Cable KABEL-UND METALLWERKE GUTEHOFFNUNGSHUTTE AG 7 July 1970 [10 July 1969 7 Aug 1969] 32908/70 Headings H1A and A4D A low-temperature cable comprises superconductors 2 attached to the inside of a carrier 1. The cable is formed on a core made of an inflated resin tube wrapped with paper or synthetic resin tape, the tube being deflated and removed after the cable is formed. The super-conductors 2 are wound with a synthetic resin foil 3 which may be of a polyterephthalate and the carrier 1 may be an ionomer applied by extrusion. As the cable cools down on passage of cooling liquid helium in use the super-conductors 2 under the foil 3 and hence not attached to the carrier 1 deflect inwards due to the different coefficients of expansion of the carrier 1 and super-conductors 2, allowing the cooling liquid helium to flow round both sides of the superconductors 2. The carrier 1 is enclosed in a plurality of coaxial tubes for thermal protection. The carrier 1 may alternatively be attached to the super-conductors 2 by an adhesive synthetic resin in which case the carrier 1 may be a polyolefin. The super-conductors 2 may be strips of a suitable material carrying a layer of lead or niobium, and the strips may be overlapped, abutted, or applied with spaced edges. Apertures may be formed in the carrier 1 to allow for the passage of the cooling liquid helium which saturates the surrounding insulation (7), Fig. 3 (not shown) which may be paper or synthetic resin, and whose dielectric strength is increased by the liquid helium.
