Abstract: 1,234,055. Stud and socket fastenings. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. 4 Oct., 1968 [6 Oct., 1967], No. 47255/68. Heading E2B. [Also in Division F2] A coupling 6..9 between a drill string 3 and a drill mandrel 1 is automatically disengaged when a predetermined pull is applied to the drill string 3 for a predetermined time. As shown teeth 8 integral with flexible strips 6 secured to the mandrel 1 are held in engagement with teeth 9b on a rod 9 by a locking ring 7 fast with the drill string 3. When a predetermined pull is applied to the drill string 3 it moves up relative to the rod 9 against the bias of a spring 15 until the ring 7 releases the strips 6 to permit disengagement of the coupling. To prevent a short pull releasing the coupling accidentally the spring chamber 12 is filled with oil which discharges through a restricted passage 24 into a chamber 10 to slow the upward movement of the drill string relative to the rod 9. In the event of an excessive pull on the drill string 3 a one-way valve 29 opens to discharge oil from the chamber 12 rapidly. The drill string may be a conventional rigid string or may as shown be a flexible drill string with the mandrel supporting a driving motor for the drill bit. The mandrel 1 may be keyed to the drill string 3 for the transmission of torque. The teeth 8,. 9b may be circular as helical ribs. In Fig. 3 (not shown) the locking ring (7) presses balls (36) carried by the mandrel (1) into engagement with a recess (38) in the rod (9). In Fig. 4 (not shown) catches (42) pivoted to the rod (9) engage a circumferential rib (41a) on the mandrel (1).

Abstract: 1,258,657. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 8 July, 1969 [18 Oct., 1968], No. 34267/69. Heading H1K. [Also in Division C7] A monocrystalline semi-conductor region supported on a substrate is produced by depositing a film of crystallizable semi-conductor material on said substrate and irradiating a selected portion or portions of the film with a pulsed laser beam of intensity sufficient to cause the formation of a monocrystal or monocrystals in the crystallizable material, but insufficient to evaporate the latter. The crystallizable semi-conductor material may be Si, Ge, In, Sb, gallium arsenide or CdS, and it may be deposited by sputtering, vapour deposition, or thermal decomposition techniques on a substrate which may be alumina, silica, silicon carbide or nitride, diamond or ruby. The thickness of the semi-conductor film is preferably 1-10 Á, and the substrate should be chemically polished. A semi-conductor layer 10 may be made monocrystalline and doped by placing on it a glass plate 20 with dopant 22 thereon (Fig. 5), irradiating (Fig. 6), and removing the glass plate to leave the doped layer 10 (Fig. 7) which may be coated with a further semiconductor layer which will deposit epitaxially over the monocrystalline doped areas 24 but will be polycrystalline or amorphous elsewhere.

Abstract: 1,264,464. Controlling heating elements in electric kettles. OTTER CONTROLS Ltd., and J. C. TAYLOR. 18 April, 1969 [18 April, 1968], No. 18446/68. Heading H5H. [Also in Divisions A4, H1 and H2]  An electric kettle, jug or pan has two easily replaceable thermal control units 1 and 27, 28, of which unit 1 is a safety cut-out and comprises a modified plug of the type described in Specification 1,254,273 and is connected to the hollow mounting head 2 for the kettle immersion heater element 3, whilst unit 27, 28 includes a switch actuated by a bi-metal 47 upon which steam impinges via an outlet 54 from the water container when the water boils, this latter unit being removably mounted on unit 1 and providing a socket for the connection of power to the heater element 3, electric connection between the two units being made automatically upon the mounting of said second unit on unit 1. Steam can be led via a tube 64 to impinge on bimetal 47 (instead of exiting via outlet 54), as described in co-pending Application 19888/69. Separation of contacts 39, 40 causes energization of a neon lamp 46 to indicate that the water has boiled, and a push-button 59 resets the switch and bimetal 47 when depressed. Alternatively, the switch automatically resets. A second heater element (not shown), for simmering purposes may be provided, and is continuously energized or is energized only when the main heater supply is interrupted. The actuating bimetals 47, 18, Fig. 3 (not shown), are as in Specification 657,434 and operate with a snap action. Specification 1,064,643 is also referred to. The shroud 63 enclosing bimetal 47 has a narrow gap 71 between it and the kettle wall 48 for the flow of convection air over the bimetal to evaporate any moisture formed thereon and to accelerate its cooling once it has operated.

A roll of wallpaper comprises a paper substrate having a printed or embossed surface carrying a flexible transparent protective and release layer of synthetic resin and coated on its other surface with a permanently tacky pressure sensitive adhesive, the protective layer on one turn of the roll contacting the adhesive on an adjacent turn and being readily separable therefrom to allow unrolling of the roll without delamination. The paper may be made from chemical or mechanical pulp or from fibres of rayon, cellulose acetate, polyamide, polyester or glass, and may be impregnated with styrene-butadiene resin or acrylic ester copolymer emulsion. The synthetic resin coating may be of acrylic ester polymer or copolymer with vinylidene chloride or styrene, copolymers of butadiene with styrene, acrylonitrile or methyl methacrylate, vinyl acetate copolymers, plasticised polyvinyl acetate, or a polymer latex or emulsion together with a polysaccharide and mineral filler. The resin layer may contain, or be coated with, a wax or silicone emulsion as release agent. The pressure sensitive adhesive may be an acrylic ester polymer or copolymer with vinyl acetate or another acrylic ester, an ester gum, polyisobutylene, polyvinyl alkyl ether, vinyl acetate copolymer or natural or synthetic rubber usually compounded with a tackifying resin such as poly-#-pinene.

Abstract: 1288949 Binding tool MAX CORP 18 Dec 1969 [25 Dec 1968] 61789/69 Heading F2G A tool for binding a plurality of articles with a loop of tape comprises a base 1 pivotally attached to both a pin magazine 2 and a pin presser 3, the parts being urged apart by springs 5, 6. A push rod 9 is adapted to pivot a spring-returned tapeholding plate 13 away from a tape-receiving plate 15, and an operating member 12 affixed to the presser is adapted to depress the push rod when the parts are closed together by handle 7, a release mechanism 19 being actuated to control the longitudinal movement of the push rod when so depressed. Tape A is fed from a reel 28 through gap 26, 27 and is allowed to project slightly. On operating the handle 7 the push rod 9 is depressed and the release mechanism 19 allows the rod to move rightwards away from plate 13, thereby allowing projection 14 to grip the tape in a hole 16 in plate 15. Release of the handle 7 allows the base 1 and pin frame 2 to separate, a length of tape being pulled out between these members. Reoperation of the handle 7 bends the tape into a loop between the "jaws" into which loop the articles are positioned. On closing the "jaws" a pin B is forced by the pusher 3<SP>1</SP> to pierce the tape and its ends are turned under by the anvil 25 while cutter 29 severs the tape. The release mechanism 19 forces the rod leftwards to disengage the holders 13, 15 and release the tape. Release of handle 7 allows separation of the "jaws" the push rod 9 being returned past gap 21 by pivoting of lever 20, a small tail of tape is left.
