Abstract: 377,737. Waxing sewing threads. BRITISH UNITED SHOE MACHINERY CO., Ltd., Union Works, Belgrave Road, Leicester. April 29, 1931, No. 12577. [Class 112.] The liquid wax receptacle has an airtight cover and means for admitting the thread while preventing the circulation of air within the receptacle. In one form, Fig. 2, the receptacle is mounted on a bracket on the sewing-machine. The cover 10 supports the wax-pot 12 and carries thread guides 14, 16 and a tensioning device 18. The wax-pot 12 is made of glass, its rim fitting against a gasket 20 under the cover. The ends of a member 24 of relatively rigid material are pivoted to diametrically opposite points in the edge of the cover, the member swinging under the wax-pot. This member carries a screw 30 for pressing the wax-pot up to the gasket to seal the joint. The cover has a screw threaded opening into which a tube 48, extending well into the pot, is screwed. On the lower part of the tube is a member 52 with fingers 56, 58 enclosing a folded sheet of felt 60. The thread 62 is passed round a pulley 68, traversing the whole length of the felt pad twice. This pad, being almost wholly immersed in the liquid wax 64, thus ensures a thorough waxing of the thread. The projection of the tube 48 well into the wax seals the entrance aperture of the thread against air. The exit is sealed by two members 76, 78, adjustable by a thumb-screw to the exact diameter of the thread. These members also strip off excess of wax. The member 76 is spring held so as to allow passage of knots &c. The tube has a funnel 84 at its upper for permitting the replenishing of the wax-pot. In applying the invention to boot sewing machines, a series of units, for wax &c., Fig. 8, may be secured to the machine. Each unit has a main supporting frame 116, a cage 124, a spring 132 to press the pot upwards to form an air-tight joint, a thread guide 140 and tension 138. The various units may be used for different coloured threads with wax &c. of corresponding colours.

Title: Long-cycle continuous annealing of strip metal
IPC: C21D9/56
Filed: 1958-04-22
Abstract: 840,992. Heat treating strips. SENDZIMIR, T. April 22, 1958, No. 12705/58. Class 72 A process of continuously annealing metallic strip material comprises bringing a single strand up to the desired annealing temperature followed by causing it to drop freely on to a conveyer moving at a slower speed than the strip in a soaking zone, thus causing an accordion-like accumulation of folds of the strip to be formed, subjecting said accumulation to soaking temperatures, and then turning said accumulation upside down at a position remote from the point of formation and withdrawing the strip in a single strand upwardly from the said accumulation. As shown (Fig. 1) strip 1 of coil 3 passes through pinch rolls 2 into welder 4, through pinch rolls 5, to looper 6, pinch rolls 8, and into zone 7a of heating zone 7 where an oxidizing atmosphere may be maintained to free the strip from oils or grease, and thence through partition or seal 9 into reducing portion 7b which is connected to the principal furnace zone 10. Alternatively a chemical pre-cleaning step employing wetting and drying may be used. The strip passes over roller 12 and falls in an accordion-like fashion on to conveyer 14 which feeds towards conveyer 13 by which it is inverted, and travels thereon through the furnace until it is withdrawn over roller 18, and through pinch rolls 21 into zone 20 where it may be cooled by cooling tubes 22 and thence it may pass through a coating metal bath 23 followed by withdrawal over further rollers and recoiling at 29. An alternative embodiment, Fig. 2, shows a modification of the conveyers where conveyer 14 is replaced by chain conveyer 30 and in Fig. 3 it is shown replaced by wheel 37. Specification 453,803 and U.S.A Specification 2,197,622 are referred to.

Title: Improvements in and relating to direct positive silver halide photographic emulsions
Inventor: MATSUO TATSURO
IPC: G03C1/485
Filed: 1969-03-11
Abstract: 1,212,142. Direct-positive silver halide photographic emulsion. RICOH K.K. March 11,1969 No.12825/69. Heading G2C. A direct-positive, photographic material comprises a support coated with a silver halide gelatine emulsion which contains less than 3% by weight of gelatine. The said material may be a colour material where the silver halide is dye-sensitized. The material may be a tripack direct-positive colour photographic material wherein each layer comprises a silver halide gelatine emulsion containing less than 3% by weight of gelatine. The directpositive material of the present invention is prepared by dispersing silver halide in an aqueous solution containing less than 3% by weight of gelatine, ripening the emulsion at temperatures between 50‹ C and the emulsion boiling point, coating the ripened emulsion on to a support and immediately air drying the product at a temperature between 50‹ C and 140‹ C. In the case of the said colour-material the ripened silver halide gelatine emulsion is mixed with a sensitizing dye and a  coupler before coating it on to the support. The sensitive material thus obtained shows a strong tendency to solarization, i.e. considerable reversal of tonal contrast when exposed to light.

Title: Improvements in or relating to Electrical Switching Means.
Inventor: GRAHAM EDWARD ALFRED
IPC: H01H37/68
Filed: 1919-05-21
Abstract: 136,101. Graham, E. A., Rickets, W. J., and Sanftleben, E. A. May 21, 1919. Relays. - A thermally-operated switch or relay has resilient supporting means for the thermal element adapted, in the event of rupture of the latter, to modify the circuit which would subsist in its absence; the supporting means remains stationary during the normal operation of the switch. In Fig. 1 the thermal element a is stretched between a fixed member b and a spring lever c. The normal circuits are that of the thermal element between terminals A, B including the lever c, and a relay circuit between terminals A, C including the lever c, spring contact lever d operated by the thermal element a, and a spring contact g. Should the thermal element break, the relay circuit is prevented from closing by the spring lever c which interrupts it at c<1> and may connect a resistance r between the terminals A, B in substitution for the thermal element a, or short circuit it. Fig. 2 shows a form in which the oblique action of the thermal element operates the contact lever d. Fig. 3 shows two resilient supports c, c<3> for the wire a, a substitutional substance r being introduced by the lever c<3>, whilst the lever c interrupts the relay circuit which would otherwise close if wire a should break. Fig. 4 shows a form in which the spring lever d is arranged to break circuit on the expansion of the thermal element, the lever c in this case closing at m<1> the relayed circuit between terminals C, D if the wire a should break. Fig. 5 shows an application to an interrupter for advertising purposes, the terminals A, B being periodically short-circuited between the members d, g. Should the wire a break, the lever c opens the circuit including these members, and the controlled lamps l consequently are prevented from receiving current. The main elements of the relay structures may be of the same metal as the thermal element to avoid gradual temperature variations affecting the apparatus. The relays may be enclosed in exhausted vessels or vessels filled with gas or non-electrolytic liquid. The thermal element need not be a wire, or it may consist of several wires in parallel. It may be thickened at or near its points of attachment by coating it with metal, such as copper, or providing it with a metal sheath, for example, of lead, at these parts. To prevent broken portions of the wire making undesirable connexions, a guard piece s, Fig. 1, of insulating-material may be used.

Patent GB-133331-A (GB)
IPC: B64C17/00
Abstract: 133,331. Macy, A. J. July 23, 1917. Balancing.-Relates to automatic stabilizers for both the longitudinal and lateral control of aeroplanes, means being also provided to maintain the machine at a safe angle of incidence when vertical gusts are encountered. To control the longitudinal and lateral stability, two sets of mechanism, each substantially the same as that described in Specification 133,330, are employed, the pendulum board of one set being arranged transversely and the other longitudinally of the machine; the driving-shaft 46, Fig. 17, for the clutch elements is, however, normally driven from the main engine 48 of the machine through a clutch 78, 80, a subsidiary motor 95 being provided to drive the shaft through a belt 97, should the engine 48 stop or slow down excessively. When the engine 48 is running normally, a conductor plate 84 is drawn into contact with a brush 85 by the pull of a centrifugal governor 83 so that a circuit is closed through a generator 86, driven from the engine, and a storage battery 90, which is thus charged. When the engine 48 stops or slows down, the governor 83 thrusts the plate 84 into contact with a brush 93, and the circuit is completed through the storage battery 90 and the motor 95. The means for maintaining the machine at a safe angle of incidence comprise a small auxiliary plane 101, Fig. 2, which, when vertical gusts are encountered, brings about a movement of the pendulum board 18 controlling the longitudinal stability. The plane 101 is mounted on a transverse horizontal shaft 102 provided at its end with a switch arm 103, Fig. 19, moving over an insulated plate 105 provided with suitable contacts. When vertical gusts are encountered, the movement of the plane 101 causes the arm 103 to close the circuit to a double solenoid 111, which tilts the pendulum board 18 through a rod 109. Specifications 133,332 and 133,333 are referred to.
