Filed: 1973-10-12
Abstract: 1490194 Sheet forming PLASTONA (JOHN WADDINGTON) Ltd 4 Oct 1974 [12 Oct 1973] 47848/73 Heading B5A [Also in Division B8] A bead 24 is formed on a component of thermoformable synthetic plastics material, e.g. a lid, by heating a sheet of material and clamping it between one-piece male and female dies 48 and 28 respectively, moving the dies together to perform a shearing opeation on the material and forcing it into the bead cavity, the clearance between the dies in the region of the cavity being less than the initial thickness of the material. The operation of forming the component can be assisted by gas under pressure, and forced cooling can be used. The dies have air vent passages (46) and (62), Figs. 4 and 5, not shown. The male die in Figs. 9 to 11, not shown, has a frusto-conical face (52A) without a step. The bead can be in the form of a screw-thread. The plastics material can be polypropylene, polystyrene, PVC or polyethylene.

An elongated steel workpiece 1, e.g. axle shaft or bolt, is inductively surface heated by rotating it about its axis in the heating position, e.g. mounted between centres 2, 3 under a liquidcooled inductor 8-10, and subjecting it at its mid-point to a biasing load, e.g. by urging a strut 4 carrying rollers 5 into contact with the workpiece, to produce a deflection in the workpiece, e.g. 0À02-0À5% of the workpiece length, during and preferably also before heating, then quench hardened. The strut 4 may be lifted and lowered electrically, hydraulically or pneumatically, and at least one of the rollers 5 may be provided with drive means. The inductor may comprise two elongated heating conductors (11, Fig. 3) fitted with magnetic yokes (12) arranged to form a closed loop above the workpiece.

Title: Catalytic reaction apparatus
IPC: C01B3/38
Filed: 1977-11-18
Abstract: The catalytic reactor plant is to work at high thermal reactor efficiencies and be of compact construction. It contains annular reaction chambers (26) which are arranged within a furnace (12). The heat for the reaction is supplied in part by hot furnace gas which, in countercurrent to the stream through the reaction chamber (26), flows within a narrow ring (48) which is arranged coaxially to, and in immediate contact with, the outer wall face (22) of the annular reaction chamber (26). In addition, regenerative heat is produced from the reaction products which leave the reaction chamber (26) and, in countercurrent to the stream through the reaction chamber (26), flow within a narrow ring (48) which is arranged coaxially to, and in immediate contact with, the inner wall (24) of the reaction chamber (26) and carries the reaction products which are essentially insulated from the heating effects of the hot gases within the furnace (12). A large number of reactors (20) can be accommodated in a compact furnace volume. <IMAGE>

Abstract: O,O - Dimethyl S - (1,2 - dicarbethoxyethyl) phosphorodithioate, and other sulphur-containing phosphorus insecticides mentioned in Specification 960,013, are deodorized by treating, in the presence of oxygen or an oxygen donor, with a chelate complex compound formed by a metal exhibiting more than one valency state, e.g. Cu, Cr, Co, Pb, Mn, or Hg, and an organic compound of the general formula <FORM:1084835/C2/1> where R and R1 are hydrocarbon radicals. Specific organic compounds are esters of acetoacetic acid and pentan-2,4-dione. Specified oxygen donors are organic peroxides, e.g. methyl ethyl ketone peroxide.ALSO:A deodorised insecticidal composition comprises a sulphur-containing phosphorus insecticide which forms thiol groups on decomposition e.g. Malathion (Registered Trade Mark) a chelate complex compound formed by a metal exhibiting more than one valency state, such as copper, cobalt, lead, chromium, manganese or mercury, and an organic compound of the general formula: <FORM:1084835/A5-A6/1> where R and R\sv are hydrocarbon radicals, and oxygen or an oxygen donor.  Specified organic compounds are esters of acetoacetic acid and pentain-2,4-dione.  Specified oxygen donors are organic peroxides, e.g. methyl ethyl ketone peroxide.  A composition comprising the sulphur-containing phosphorus insecticide and the chelate complex compound, when stored in the presence of air, will become deodorised.  When the insecticide is deodorised, the presence of the chelate compound, together with air or other source of oxygen, will keep the insecticide free from disagreeable odour.

Filed: 1966-10-29
Abstract: 1,145,523. Circuits employing bi-stable magnetic elements. FERRANTI Ltd. 5 Oct., 1967 [29 Oct., 1966], No. 48589/66. Heading H3B. In a coincident current storage matrix comprising two or more pairs of bit planes, Fig. 2, each row conductor X traverses one row of storage elements in each one of the bit planes and each column conductor traverses one column of storage elements in each of a pair of bit planes and has a connection at a point between the two columns of storage elements traversed by it to a corresponding point on one only of the other column conductors traversing columns of storage elements in the same pair of bit planes. Each bit plane, Fig. 1 (not shown) is divided into four parts, each part having a separate sensing wire which passes through all the cores in that part of the bit plane. Each end of a Y conductor in a single pair of planes p, q is connected to a switch a, c, b, d to semiconductor Y drive selection circuitry, Fig. 3. In order to write information into rp, rq current in the X conductor is caused to flow from right to left in plane p and left to right in plane q, switches a and c are closed, Fig. 3a, and current caused to flow upwards along the left hand Y conductor. Cores sp and sq are switched by closing switches b and d and reversing the current flow in the X conductor. In order to write current into only core rp switches a and d are closed, Fig. 3b, so that current flows through cores rp and sq and the current in the X conductor is the same as in Fig. 3a. The two half currents combine at core rp and cancel out at core sp so that no core in plane q is switched. Core rq may be switched, Fig. 3c, in a similar manner by closing switches b, c. In order to read out, corresponding bits in each plane are interrogated simultaneously. The Y conductor current is caused to flow downwards, Fig. 3d, and the X conductor current flowing in the direction shown causes cores rp, rq to be interrogated. Cores sp, sq are interrogated by reversing the flow of current in the X-conductor. During read out the four sense wires of each plane are strobed so that only the output from the required sense line is used so as to eliminate noise in the other three sense wires. The two planes of a pair may be located on opposite sides of an insulating plate. The system may be used with a two-wire store in which one of the sets of conductors is used both for writing and sensing purposes. The storage elements may be thin films or apertures in plates of magnetic material.

[Class 40 (iv)] In a system in which a calling party's number is transmitted by impulses of alternating current from identifying apparatus at the originating exchange to ticketing equipment at a central exchange, the impulses are sent over the junctions in a simplex circuit and are byepassed around the feed bridges at the originating and tandem exchanges. As shown, the junctions have bridge terminations with a grounded mid-point and are coupled to the A.C. signalling circuits through transformers ST1 -4. When the ticketing equipment ATM is ready, relay Bi sends back a signal of 50 cycles to the tandem exchange, where Ci, Ch repeat the signal to the originating exchange. First, a relay (not shown) responds and causes a switch CS to connect the signalling circuit to the junction, and then the signal operates Sf, which connects both direct current and 450 cycle current to the fourth wire of the switch train. Relay Id energizes and a switch ILF associates the identifying apparatus. The calling party's number is now sent forward over the fourth wire by impulses of A.C. of 125 cycles, which pass through transformer GT2 and valve RV .to relay A, and corresponding impulses of 50 cycle current are sent over the junction by Is2.
