Title: Improvements in or relating to transportable habitable constructions
IPC: E04B1/344
Filed: 1954-04-23
Abstract: 761,276. Portable buildings. TERRAPIN, Ltd., [formerly TERRAPIN DWELLINGS, Ltd.]. April 23, 1954 [Sept. 8, 1953], No. 11805/54. Class 20(1)  A rigid framework comprising a floor, roof, and end walls with aligned doors, includes a set of flaps hinged to each of two opposing sides of the framework which can be opened out to provide further floor, roof, and end wall sections, and side walls. The opposing doors in the end walls enable a number of the expanded structures to be placed end to end with the doors in alignment, thereby providing a continuous communication between the structures. The floor of the framework consists of transverse bars 102, Fig. 1, connected to longitudinal bars 100, 101, and uprights 103 which support a roof 105 comprising girders 106 and tie bars 107. Cross-bars 109, 110, Fig. 2, connected to the uprights 103 strengthen the framework. End wall flaps 113 are pivoted on vertical axes to the uprights, and side floor flaps 118 are pivoted on horizontal axes to the longitudinal floor bars. Side wall flaps 121 are hinged to the flaps 118 and roof flaps 124 are hinged to the roof 105. Fig. 3 shows the flaps in folded position. Angle plates are secured to the lower edges of the flaps 113 and provide a seating for the floor flaps. Vertically extending plates on flaps 113 provide abutments for the side wall flaps 121 which are bolted thereto. Bracing straps 130 extending across flaps 113 are bolted to bars 132 secured to the uprights. When a number of such structures are aligned the small gaps therebetween are covered with felt joined to wooden fillets attached to the outer edges of flaps 113.

Patent GB-569888-A (GB)
Title: Improvements in or relating to control gear for 3-phase induction motors
IPC: H02P1/34
Filed: 1943-07-21
Abstract: 569,888. Control of A.C. motors. IGRANIC ELECTRIC CO., Ltd., and TAYLOR, J. R. July 21, 1943, No. 11864. [Class 38 (iii)] Automatic slow speed running of a threephase induction motor for driving a skip hoist or the like is obtained by unbalancing the stator circuits by means of an autotransformer. As shown in Fig 1, for normal speed the stator windings A-C of the motor M are supplied directly from the lines L-L3 through either forward or reverse contactors Fc, Be and a twopole high speed contactor HS. Slow speed is obtained by opening the contactor HS and closing a triple-pole contactor LS which connects an auto-transformer T across the lines L2, L3 and thereby applies a voltage greater than the line voltage to the winding B and a voltage to the winding C which is connected to the transformer by an adjustable tap Tc. The rotor windings D-F are connected to starting resisances R which are cut out by accelerating contactors 2R-5R. The controller is connected across lines L1, L2 and includes a forward pushbutton FWD, Fig 2, which, on depression, energises the self-holding directional contactor Fc. A control relay CR is thereby actuated to cause energisation of the high speed contactor HS and to open the energising circuit of the slow speed contactor LS which is normally closed by the back contacts of the relay. Timing relay contacts on the contactor HS then close with delay and energise the accelerating contactor 2R which cuts out the first section of rotor resistance and also closes timing relay contacts for the next contactor 3R. Contactors 4R, 5R are similarly closed in turn. When the motor is to slow down, a forward slow down limit switch SDF.LT is opened. The control relay is thus de-energised and the contactors HS, 2R-5R, in consequence, drop out, whilst the .back contacts of the control relay close the energising circuit of the contactor LS. A forward final limit switch FLT is also provided, on the opening of which the forward directional contactor Fc drops out and the motor stops, with or without the aid of an electromagnetic brake. Reverse motion is controlled by a "backward" push button BACK, a slow down limit SDB.LT and a final limit switch BLT.

Title: Process for covering a floor, wall or ceiling surface
IPC: C08L67/06
Filed: 1969-03-06
Abstract: 1,262,524. Ornamenting. GLASURITWERKE M. WINKELMANN A.G. 6 March, 1969 [8 March, 1968], No. 11978/69. Heading B6G. A floor, wall or ceiling surface is covered by applying a liquid, solvent-free cold-curing synthetic resin composition and a curing agent for the resin selected so that the hardening of the resin by the curing agent is not instantaneous, electrostatically depositing textile fibre flock on the surface of the resin before it has hardened to an extent such that the flock particles cannot penetrate, at least partially, the surface and thereafter allowing the completion of the cure of the resin at room temperature. The surface can be jointless composition flooring, a cementbound jointless composition, compositions based on binders such as lime and gypsum and on bitumen or asphalt, concrete, artificial stone, plaster and wood, particularly wooden floors. The term "solvent-free" is defined as not containing a volatile organic solvent. Solvents that participate in the curing reaction may be present, e.g. styrene, vinyl toluene, acrylic acid esters, methacrylic acid esters. Suitable solventfree compositions are those based on non- thermoplastic polymers such as (1) hydroxyl group-containing compounds such as polyethers, polyesters, alkyd resins, acrylic and epoxy resins (which cure with polyisocyanates), (2) epoxy resins (which cure with the aid of polyamines, amidoamines or ketimines), (3) acrylic compounds or unsaturated polyesters mixed with copolymerizable monomers, e.g. styrene, vinyl toluene, acrylic acid esters, methacrylic acid esters (which cure with peroxides), (4) polysulphides (which cure with heavy metal peroxides, e.g. lead peroxide or manganese dioxide). The curing agent may be admixed with the resinous materials before processing, or alternatively a curing agent and the resinous material can be applied separately on to the surface by a two-component spray device, or the curing agent can be applied first followed by, in a separate operation, the application of a layer of the resinous material. The resinous materials may contain pigments and/or fillers such as talc, barium sulphate, mica, asbestos, quartz or sand. The compositions may be applied by brushing, roller, spraying, casting or trowelling. Suitable textile fibres are of cotton, coconut, wool, goat hairs, viscose rayon, triacetate or polyamide flock, and are preferably of length 0À3 to 12 mm. The flocking may be carried out using screen diffusers in an electrical hightension field or by means of electrostatic spray guns. The fibres may be of uniform or varying length, or fibres of different length can be incorporated by flocking in two or more successive operations, and fibres of different colours can be used.

Title: Improvements in or relating to apparatus comprising one or more gas-oxygen burners
Inventor: NELSON EVAN HERBERT
IPC: H01J9/32
Filed: 1956-04-19
Abstract: 830,339. Oxygen-combustible gas burners; turret machines. GENERAL ELECTRIC CO. Ltd. April 11, 1957 [April 19, 1956], No. 11981/56. Classes 39(2) and 75(1) [Also in Groups XXIX and XXXVI] In an oxygen-combustible gas burner the effect of blow back is reduced or eliminated by introducing under pressure an inhibitor gas (i.e. a gas or mixture, such as air, which does not form a highly explosive mixture with oxygen) to the oxygen feed line to the burner to effect a scavenging of this latter feed line between the oxygen control supply valve and the burner with a flow of the inhibitor gas when the oxygen supply valve is closed. When the burner or burners is or are used for forming a seal between a conductor rod and a quartz wall, the seal region of the wall is heat softened and pressed into contact with the conductor, the flame extinguished by turning off the oxygen and gas and the inihibtor gas passing through the burner is directed on the seal to cool it. To carry out the steps in the formation of such a seal a "lapped" valve assembly 7 consisting of two relatively rotating discs 8, 9 is employed, the disc 8 being fixed and the disc 9 being rotatable as by a handle 16 about a stud 10 secured in the disc 8, a spring washer 11 holding the discs resiliently in contact. Bores 12, 13 extend through the disc 8 and connect up the oxygen and gas supply lnes 20, 21 through corresponding bores 14, 15 in the disc 9, when suitably positioned to conduits 5, 6 leading to a mixing chamber 4 from where the combustible mixture passes through pipes 3 to burners 1 having jets 2. The bore 13 registers with an arcuate groove 24, Fig. 2 (oxygen and gas valves open) in the undersurface of the disc 9 and terminating the bore 15. The disc 9 also has a bore 17 communicating at its inner end with an arcuate groove 25, Figs. 2 and 5, in the undersurface of the disc 9 and connecting at its outer end through a tube 18 to the oxygen line 5 at a point near to the disc. The groove 25 registers with a bore 19 in the disc 8 connected to a compressed air supply line 22. The arrangement is such that when the oxygen and gas supplies are cut off as in the position of the discs shown in Fig. 5, a slight flow of air passes from the groove 25 through the bores 19, 17 to the tube 5 through the pipe 18 and out through the burner jets 2 which may be directed on to the seal located therebetween. Clockwise rotation of the disc 9 first admits gas from the bore 13 through the arcuate groove 24 bores 13, 15 and pipe 6 to the mixing chamber 4 and then oxygen through the bores 12, 14 whilst there is still a flow of air, and further rotation cuts off the supply of compressed air through the bore 19 and groove 25 and bore 17 to the pipe 18 and only oxygen and gas reach the burners, which are lit by a pilot flame 23.

Abstract: 1,215,932. Rotary switches. PLESSEY CO. Ltd. 13 March, 1968 [15 March, 1967], No. 12054/67. Heading H1N. The rotor spindle 1 is rotatably coupled to the output 17 of a spring-ball type index mechanism 16 through flats (18, Fig. 2), and a shaft 19 connected to the input of the index mechanism is rigidly connected to a knob 20 through a screw 21. Spindle 1 is axially clamped through a plug 25, and after removal of this plug 25, a tool inserted in a hole 28 in the spindle facilitates withdrawal of the spindle 1 through the knob 20 from mechanism 16 and from the rotor assembly 3, 4, 5 and double sided printed contact stators 7, 8, in order that the stators, 7, 8 can be replaced. The stators slideably fit in grooves in the switch casing. The insulating rotor supports 5 are locked together by studs and holes (11, 12, Fig. 2). In an alternative arrangement (Fig. 3), the switch spindle (30) is coupled to the actuating mechanism through an Oldham coupling (31). An actuating spindle (36) may be coupled to the input of the index mechanism (32) while the output is connected to the Oldham coupling, or the spindle (36) may be secured to the Oldham coupling and actuate the index mechanism through co-operating flats. The rotor spindle (30) and switch members can be disconnected from the parts 31, 32 and 36 by displacing the switch assembly in a direction perpendicular to the rotor spindle, this being facilitated by co-operating surfaces 37, 38. The rotor spindle (30) can thereafter be axially withdrawn from the switch members.

Abstract: 536,007. Welding chains. GORDON, S. H. July 23, 1940, No. 12068. [Class 83 (iv)] In making a welded chain link from two part links and a transverse stud, the two part links are abutted along a line displaced from the minor axis by an amount equal to half the width of the stud with the ends of the longer part link and of the stud shaped so that the stud is located and locked at least in one direction, the stud is assembled with the part link and the two part links are then united by automatic electric-resistance welding. In Fig. 1 the studs 14 are formed with toric ends to fit between the limbs of the larger part link 10 being concave in the longitudinal direction and convex in the transverse direction. The stud is sprung into place prior to welding by forcing it endwise between the free ends of the part link 10. The ends of the part links 10, 12 are provided with extra metal 18, 20 which is burnt out during welding and the final weld line is about level with the corners 22 between the stud and the sides of the link. In Fig. 2 the part link 10 is formed with flat seating surfaces 26 with transverse grooves 28 having closed ends, in which fit similar projections 30 on the ends of the stud. As the stud in this case is only retained in one direction by the closed end of the groove the extra metal 18 is positioned and the part 20 formed with projections 32 so that during welding of the part links, the part 12 is also welded to the ends of the stud. Longitudinal grooves may replace the Transverse grooves.
