Title: A new or improved electromagnetic control device for the periodic operation of electric switch contacts
Inventor: HALL RICHMOND ERNEST
IPC: H01H51/32
Filed: 1954-12-29
Abstract: 781,316. Electromagnetic interrupters. PLESSEY CO., Ltd. Dec. 29, 1955 [Dec. 29, 1954], No. 37514/54. Class 38 (5). An interrupter employing the electromagnet disclosed in Specification 779,951 comprises an armature 13 pivoted at 14 and attracted towards the position shown adjacent polepiece 12 upon energization of the winding 11. A spring blade 16 fixed at one end by a screw 17 to the armature lies, when in its unstrained condition, flat along the upper surface of the armature, the other end of the blade being connected to a link 18 pivoted at 19 to an arm 6 having a pivot 7. A toothed segment 2 on the arm 6 co-operates with a pinion 3 fixed to a plate 1 carrying a pin 30, spring arms 5 on the plate having frictional driving engagement with a flywheel 4. Initially, the arm 6 has the position shown and a moving contact blade 23 operated by a rocker 26 is held closed against a contact biade 31 to complete a circuit through the winding 11. Attraction of the armature 13 causes straining of the spring 16 as shown, this spring stress being relieved as the arm 6 rotates the flywheel 4, the corresponding clockwise movement of the pin 30 through a complete revolution causing movement of the rocker 26 from its position against stop 29 to a position against stop 28, the blade 23, provided with an undulation 24, being snapped over-centre to the open condition to de-energize the magnet. When the energy imparted to the flywheel has been absorbed by its frictional coupling with the plate 1, a spring 20 acting on the arm 6 to the right of its pivot 7 restores the parts to their initial condition and the cycle repeats after the flywheel energy has once again been absorbed. The pin 30 controls a further snap-acting contact blade 33 by engaging a slot 38 in a rocker 37 causing a changeover action of the contact 32 between contacts 34, 35, movement of the rocker 37 being normally prevented by a cylindrical cam 39 coaxially mounted with the plate 1, a flat portion 40 on the cam permitting the rocker movement when the pin 30 enters the slot.

Abstract: 1474504 Printed circuits NORTHERN ELECTRIC CO Ltd 12 Sept 1975 [23 Sept 1974] 37629/75 Heading H1R Printed circuit boards 10 of e.g. GRP having circuits printed thereon at 12 and locating holes 15 and handling apertures outpunched, are formed in multiple from a sheet 11; the periphery of each board being delineated by a shear line 14. The printed circuits 12 are formed by coating, masking and etching, and using holes 15 for location the boards 10 are outpunched in a press against a spring plate, which returns the boards into the apertures in which they are retained by frictional adhesion. Thereafter the sheets 11 are stacked and heated at a predetermined temperature under weighting pressure for flattening, and allowed to cool under pressure. Then the copper circuitry is protected by a layer of natural resin deposited from alcohol solution, and the sheets with boards in situ are translated to assembly stations where components are automatically or manually inserted, and to wave soldering stations for connection and fixture. The boards are pressed out mechanically while the surrounding sheet is held stationary. The synthetic resin of the sheets is capable of thermosoftening over a defined temperature range and may be e.g. bischlorophenyl A resin.

Patent GB-941129-A (GB)
Title: Process and apparatus for electrically resolving oil-continuous dispersions
IPC: B01D17/06
Filed: 1961-10-24
Abstract: Dispersions of particles in oil, as the continuous medium, are removed by passing the oil through an inter-electrode space of large length to gap ratio and applying a high voltage direct current, in which the bulk of the dispersed particles are coalesced and separate out in the early stage, and at a later stage particles are deposited on the electrodes by electrophoresis. Preferably the inter-electrode space is defined by a rod electrode centrally mounted in a tube of length to gap ratio 8 to 30:1 and preferably at least 12 to 25:1.  A unidirectional voltage of 6 to 30 k.v. per inch of treating space is applied.  A suitable apparatus consists of a cylindrical vessel 10 the cross-section of which is occupied by a cellular electrode assembly comprising tubes of circular or hexagonal or other cross-section 16 and mounted <PICT:0941129/C3/1> between upper and lower zones 13, 14.  Each tube contains a rod electrode 17 suspended centrally therein and attached to a frame 19 connected to a high-voltage source of D.C.  The oil dispersion may first be treated to remove coarse suspensions in a high turbulence electric treater 40, and then enters a manifold system 29 discharging streams of the oil through the vertical tube electrodes; spreaders 31 may be used. In the lower region, the oil is submitted to some turbulence and the bulk of the dispersed particles are coalesced, and then enters a quiescent zone 24 of higher voltage gradient, where finer particles are deposited on the tube electrode surface by electro-phoresis. Deposited material sinks slowly downwards on the tube surface to the bottom zone 32. In a modification, the level of the collected dispersed material is arranged to submerge the lower ends of the electrode tubes at L-L and forming a seal, by adjusting level control devices 35 controlling the discharge valve 34.  The upper zone 13 may be in the form of a header provided with a collector pipe with openings to receive the rising oil discharged from each tube electrode. The lower inlet zone 14 may also have a series of vertical barrier walls against which the dispersion impinges before entering the tube electrodes, and replaces the manifold 29.  The process may be applied to petroleum oils containing dispersed particles of water or caustic soda solution.

Title: Improvements in the bonding of rubber to metal
IPC: C08J5/12
Filed: 1963-09-30
Abstract: A rubber composition is bonded to a metal surface by adding to the rubber a minor proportion, e.g. 5-25%, by weight, of an epoxidized rubbery polymer and vulcanizing whilst in contact with the metal. The epoxidized rubbery polymers are those obtained by treating a rubbery polymer with a per-acid, e.g. perbenzoic acid, monoperphthalic acid or performic acid, or with hydrogen peroxide in the presence of a catalyst.  Suitable epoxidized polymers include the epoxidation products of natural rubber, polystyrene, polyisoprene, polybutadiene, polybutadiene-styrene or the halogenated or sulpho-chlorinated derivatives of the above polymers and other polymers such as polyethylene and ethylene-propylene terpolymers. Rubber compositions include natural rubber or synthetic rubbers such as polyisoprene, polybutadiene and polybutadiene-styrene, together with the usual reinforcing fillers and vulcanizing agents.  Said compositions with additives of epoxidized polymers are bonded directly, without priming, to brass, aluminium, iron or steel. Examples demonstrate the improved bonding obtained by the use of epoxidized polymers as additions, such additions being in amounts that give an epoxide oxygen content of 0.1 to 1.3% by weight of the total composition.  The invention may be applied to the making of tyres with steel cord inserts, driving belts, pressure rollers, torsion elastic springs and reinforced hoses.ALSO:A rubber composition is bonded to a metal surface by adding to the rubber a minor proportion, e.g. 5-25%, by weight, of an epoxidised rubbery polymer and vulcanizing whilst in contact with the metal.
