Abstract: 1301938 Electro-plating copper; immersion nickel plating UDYLITE CORP 13 May 1970 [19 June 1969] 23270/70 Headings C7B and C7F An adherent non-flaking Cu electro-plate is formed on a steel surface e.g. tube by treating it with an immersion Ni plating bath to form a displacement Ni deposit on the surface prior to electro-depositing Cu from an aqueous acidic Cu electro-plating bath, e.g. containing copper sulphate, fluoborate, nitrate, sulphamate, alkyl sulphonates or disulphonates, with one or more brightening and levelling additives. The steel surface may be prior cleaned with alkaline, acidic or organic solvent by scrubbing, spraying, vapour degreasing, or steam or ultrasonic cleaning, followed by applying an electrolytic Ni or Cu strike; the Ni strike bath may be the same as the immersion Ni plating bath, which is first electrolyzed then the current discontinued to form the displacement Ni deposit. The Ni plating bath may be an aqueous solution comprising NiCl 2  with or without NiSO 4  and H 3 BO 3 ; the immersion Ni plating bath may contain 100-600 g/l NiCl 2  6H 2 O, 0-150 g/l NaCl and 0-50 g/l H 3 BO 3 , with or without up to 1 g/ l anionic wetting agent e.g. nonyl benzene sulphonic acid, and one or more additives for ductilizing and/ or grain refining e.g. saccharin.

Title: An automatic stopping device for talking machines of disc type
IPC: G11B17/02
Filed: 1922-09-01
Abstract: 208,753. Findlay, R. M. Sept. 1, 1922. Starting and stopping.-Relates to devices of the kind in which a spring-operated brake is automatically applied to the machine when movement of the tone-arm across the record ceases, the release of the brake occurring when a circuit is closed through two contacts, one of which is carried by a motor-driven part, and the other being moved by connection with the tone-arm at a speed which is not less than that of the other contact. The mechanism comprises a disc A intermittently or continuously driven from the machine motor C<1> (for example by gearing C - - B) through a light friction clutch, which as shown in Fig. 2 may be constituted by pressing together the parts A, B by a spring B<2>. The disc has an arm A<1> carrying a contact A<2>, adapted to coact with a contact finger D'. This is mounted on an insulating arm D, on which is pivoted a link F having a pin-and-slot connection with the tonearm G. The contacts A<2>, D<1> are arranged in circuit with an electromagnet K<3>, controlling a detent N for the brake L<2>, contacts j, J<1>, one of which is fixed and the other carried bv the tone-arm, being also included in the circuit. In the arrangement shown, additional contacts K<1>. K<2> are also provided, the member K<2> being a hand-lever which, when moved to the contactclosing position shown, takes the brake off and shifts a part N<2> of the brake-mechanism into engagement with the detent N. On swinging the tone-arm clear of the turntable, and then placing the stylus on the record, the link F first causes the contacts D', A<2> to be drawn round together and then separated, the contact A<2> being left behind. During the playing of the record, the contact A<2> follows the contact D<1>, but does not overtake it until the movement of the tone-arm ceases. Meanwhile the contact J<1> has come into engagement with J. When the circuit is finally established at A<2>, D<1>, the magnet K<3> is energized, the detent N is attracted, releasing the part N<2>, and the bra.ke L<2> is moved by spring L<3> so as to stop the motor. In a modification, an electromagnet normally holding the brake is short-circuited when the contacts are closed. The Provisional Specification refers also to the use of similar mechanism to that described above for stopping the motor mechanically.

Filed: 1970-05-15
Abstract: 1299934 Braid and braiding machines BRINEX SA 15 May 1970 [16 May 1969] 23769/70 Headings D1C and D1K A sheath A is braided from threads of absorbent fibres 1, 2 round, a mass of powder C and an axial core B, the powder being highly hygroscopic, its grains being of a transverse dimension at least equal to the widest gaps in the braiding of the sheath. The sheath is braided on a braiding machine with carriers for bobbins 8 which move in the usual maypole fashion on a bed 6 so that threads 1, 2 from the bobbins form a braid on the surface of a ring 10. Threads 5 to form the core are fed from one or more bobbins 11 through a hole 18 in a driven screw 17 which feeds powder 13 down from hopper 12 into the braid as it is formed. The completed braid is drawn-off by pulley 15. The core may be braided and a further braid may be immersed in the powder. These will be absorbent too. The threads 1, 2 may be grouped in twos, Fig. 1, threes or fours, Fig. 5 (not shown). Threads 1, 2 may be of cotton or polyvinyl alcohol or of fibres of polyesters and acrylic resins treated with sodium derivatives. Powder C must form a gel or the like and bond the fibres to the wall of a tube to be sealed by a length of the braid when used as a wick. The powder must be stable at sterilization temperature, resistant to micro-organisms and non-toxic. Polyvinyl alcohol is best but starch, dextrin casein or cellulose esters may be used. The lengths of wick may be ten times their diameter and are compressed into tubes of glass, metal or plastic containing semen for artificial insemination or other liquid.

Title: Improvements in fluid pressure reducing and regulating valves
IPC: B60T15/04
Filed: 1932-08-25
Abstract: 403,181. Fluid actuated valves. CONSOLIDATED BRAKE & ENGINEERING CO., Ltd., and PORTER, A. S., Windsor Works, Slough. Aug. 25, 1932, No. 23826. [Class 135.] Valves controlled by pilot or relay valves.- In the pressure regulating and reducing valve described and shown in Specification 177,195, [Class 135, Valves &c.], the lower pressure, in the train-pipe, which is applied to the space 16, is exhausted through a relief valve 19 if the pressure rises too high owing to leakages from the reservoir through the main valve 1. The relief valve is carried in a plunger 10 bearing against the diaphragm 7. The relief valve is urged towards the open position by a spring 20, but is normally prevented from opening by its stem 21, which abuts against the stem of the auxiliary valve 6. When the pressure in the train-pipe rises too high, it forces the diaphragm to the left from the position shown, so that the seat in the plunger 10 is withdrawn from the relief valve 19. Air then passes between the valve-stem 21 and the aperture in the diaphragm clamping-screw 23, past the neck 27 of the valve 19, and through ports 24, 26 to atmosphere. If, on the other hand, the pressure in the trainpipe falls too low, the diaphragm 7 is moved to the right by its spring 8, and, through the stem 21, opens the auxiliary valve 6, thus admitting high pressure from the conduit 13 through conduit 18, and behind the piston 2, which then opens the valve 1 and admits air to the conduit 14 connected to the train-pipe.
