Patent GB-287498-A (GB)
Title: Means for indicating the position of electric switches
IPC: H04Q9/04
Filed: 1927-11-30
Abstract: 287,498. Siemens & Halske Akt.-Ges. March 22, 1927, [Convention date]. Switching-systems.-Devices for indicating the position of a line switch, which can be released by a line protection relay, are arranged to be operated not only by the line switch but also by the relay, thus indicating, when the switch has been closed on a short circuit, that the switching-in and the automatic switching-off have occurred. An oil-switch in a secondary room N is arranged for operation in a main control room H by means of a switch 19 and contact discs 17, 18, the arms 15, 16 of which are arranged to move synchronously. To close, the switch 19 is moved over to contact 20 to send a + current impulse through contacts 23, 24, and polarized relay 29, and by means of a contact arm 8 engaging a contact 31, energizing a switch closing coil 3. This coil pulls over the armature 2, which is keyed to the operating spindle 1 of the switch, and the switch is latched in by a lever 5. When the arms 15, 16 leave contacts 23, 24, the arm 8 returns to zero position and cuts out the coil 3. The return of the arm 8 is delayed by a hold-on coil 46 which is cut out after a certain time-interval by a bimetallic strip 48 and switch 49. To open the switch, the switch 19 is moved over to contact 21 and a - impulse is sent through the polarized relay 29, thus closing a circuit through the contact 32 and coil 7, which attracts the lever 5 and allows the switch to open. The indicator device 43 is operated through a polarized relay 42 and contacts 40, 41 by means of a two-way switch 35 coupled to the armature 2. According to the position of this switch a + or - impulse is sent through the relay 42 to operate the indicator. A current transformer 51 is arranged, on overload or short-circuit, to close a circuit at 53 through the coil 7 to open the main switch. Simultaneously the coil 55 is energized to indicate if the switch was switched into a shortcircuit, even though it may have been tripped open again before the arms 15, 16 had reached the contacts 40, 41 and given an indication. In these conditions, the tripping current passing through a coil 55 attracts an arm 44 on to a contact 57, thereby sending a + impulse to the indicator to show that the switch has been closed. This movement of arm 44 also cuts in a holding coil 58 and a bimetallic strip 61, the latter cutting out the coil 58 after a lapse of time for the operation of the indicator. After the de-energization of the coil 58 a - impulse is sent to the indicator by way of arm 44 and contact 45, thus indicating that the switch was switched out again. The return of the arm 44 could alternatively be effected by the indicator current impulses or mechanically by the arm 16. The circuit of the hold-on coil 3 may be adapted to be controlled by the circuit at 53 so that the armaturee 2 may not be held on too long.

Title: Improvements in cylinder locks
IPC: E05B55/00
Filed: 1947-12-09
Abstract: 635,174. Barrel locks. DISSING, H. C. Dec. 9, 1947, No. 32455. Convention date, July 14, 1945. [Class 44] A barrel lock comprises a lock casing, inner and outer cylinders both rotatable relative to the casing and to each other, rotation of the outer cylinder being resiliently restrained, the arrangement being such that unless the correct key is inserted, the outer cylinder turns with the inner cylinder and prevents coupling means engaging to release the lock. The inner cylinder 17 is secured to discs 7, 8 united by pins 9, 10, 11. The outer cylinder 16 has a lug 18 containing a series of tumblers which is received in a quadrant cut out of the casing wall. The sleeve 14 is secured to the disc 8 and turns with the inner cylinder, the slot through which the lug 18 passes being wide enough to allow some relative movement. The sleeve 25 has a narrow slot engaging the lug 18 and therefore moves with the outer cylinder. An arm 27 on this sleeve is spring loaded to bias the lug against the vertical end of the cut-out. A lever 31 mounted on the pin 11 is spring loaded to urge a tongue 32 towards a notched projection 29 but is normally held out of contact by a stop 33 on the case. When the correct key is inserted and turned the inner and outer cylinders are disconnected and the inner cylinder and the discs rotate, the outer cylinder being detained by the spring 28. The end of the lever leaves the stop 33 and rises to engage the tongue 32 in the notch 30 so that the hooked end 42 engages a pin 38 and transmits the rotation to a lever 37. The lever 37 abuts a shoulder 39 to retract the bolt. If the wrong key is used, the inner and outer cylinders turn together so that when the lever 31 is released from the stop 33 the tongue 32 engages the projection 29 and prevents the hook 42 engaging the pin 32. Rotation of the key will then be ineffective to retract the bolt.

Title: Coating compositions and applications thereof
IPC: C08K3/00
Filed: 1949-12-19
Abstract: A coating composition for use in preparing water-impermeable water vapour permeable coatings is obtained by dispersing in a dispersion of a water-insoluble coating material a finely-divided, solid, non-porous filler having a wet density in toluene of not more than 80 pounds per cubic foot in an amount not less than that represented by the formula X=45.87+21.44y-0.938y2+1.625ys in which X equals grams of filler per 100 c.c.s. of the coating material and y equals one-tenth the wet density, in pounds per cubic foot, of the filler in the dispersing medium of the dispersion.  The fillers may be calcium carbonate, particularly in the precipitated form, bentonite, Irish moss, water ground mica, magnesium carbonate, graphite, silica, titanium dioxide, air-floated fibrous magnesium silicate, iron oxide, channel black, semi-reinforcing furnace black, conductive furnace blacks, ultrafine blacks, pyrophyllite, aluminium silicate, clay and talc.  The coating materials may be polymers of chloroprene, isoprene, butadiene; and copolymers of butadiene-1,3 or isoprene with styrene, acrylonitrile or acrylates; polyvinyl chloride; copolymers of vinyl chloride with vinylidene chloride, vinyl acetate, diethyl fumarate, diethyl maleate and acrylates; polyvinyl butyral; polyvinyl alcohol; copolymers of isobutylene with butadiene or isoprene; polyamide polyesters; and polymers of methyl acrylate, methyl methacrylate, or methyl chloracrylate.  The coating materials may be used in aqueous dispersion or in organic solvent dispersion and plasticizers, age resisters, accelerators, waxes and resins may be added.  The coating composition is preferably used on a water vapour permeable support such as fabrics made from cotton, regenerated cellulose, cellulose acetate, linear polyamides, linear polyesters and glass and also on paper and leather.  The proportion is normally 2 1/2 to 5 ounces per square yard.  In an example 100 parts of polychloroprene, 5 parts of carbon black, 5 parts of wax, 12 parts of zinc oxide, 2 parts of phenyl beta naphthylamine are dispersed in toluene and 155 parts of specially precipitated calcium carbonate added.  After mixing 2 parts of catechol is also added.

Abstract: 364,725. Pressure-relieving devices. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., BRAZIER, L. G., and VINCENT, R. S., Hamilton House, Victoria Embankment, London. Oct. 29, 1930, No. 32492. [Class 135.] In an impregnated cable having a series of gasfilled pressure compensators disposed within a hollow conductor or within the spaces between the cable cores, the compensators are formed as closed flat cylinders, each having one or both of its end walls made of thin corrugated metal, preferably of an alloy of copper and nickel with or without zinc. The compensators may be formed by two concentrically corrugated diaphragms 8 united at their edges by flanging or by a ring 10, as shown in Figs. 2 and 3. Groups of compensators may be arranged within containers 6, as shown in Fig. 1. To allow flow of impregnating material to or from the groups, the end walls 14 of the containers are provided with apertures 25 and 'the compensators are spaced from one another by rings 12 having radial holes 13. The apertures 25 are preferably formed near the centre of the end walls 14 so that any leakage gas from the compensators cannot easily leave the container through these apertures. In the modified arrangement of Fig. 4, the apertures 25 are replaced by a tube 18 which projects internally from the surface 16 of the container and terminates at the centre of the container. As shown in Fig. 5, the use of a container is avoided by forming the group of compensators and spacing rings 12 as a unitary structure, the end compensators of the group being provided with thicker end walls 21. Specification 347,819, [Group XXXVI], is referred to.

Title: Gold deposition
IPC: C23C14/34
Filed: 1969-07-01
Abstract: 1,207,946. Gold deposition. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. July 1, 1969 [July 4, 1968], No.33104/69. Heading C7F. Gold is sputtered on a substrate of metal or an insulating material, the target cathode being electrolytically coated with an alloy consisting of gold and a small amount of a metal which is capable of forming a compound by reaction with molecular oxygen. The metal alloyed with the gold may be Co or Ni, the substrate may be Ti, Ta, Cr, Mo, a ceramic, quartz, ferrite, or glass and the target may be of steel coated electrolytically with the gold alloy. Two methods of sputtering are disclosed. Where the substrate permits diffusion of metal thereinto, the deposition apparatus is evacuated to 10<-6> Torr, flushed with argon, reevacuated, and sputtering is started so that an intercrystalline adhering layer is formed on the substrate which layer becomes subsequently coated with the gold alloy layer. Where the substrate does not permit of diffusion the vessel is evacuated to 10<-3> to 10<-4> Torr, and the procedure described above is followed, except that a little oxygen may be added to the Ar. This gives rise on subsequent sputtering to a substrate coated with, in order, a cobalt oxide layer, a cobalt oxidecobalt-gold layer, and a final thicker coating of Au-Co.
