Title: Components for watch and clock mechanisms and method for the manufacture thereof
IPC: G04B1/10
Filed: 1957-06-03
Abstract: Frictionally engaged surfaces of components for watch or clock mechanisms which are subject to sliding engagement with another part of the mechanism, or with themselves are coated with tightly adhering thin layers, not exceeding 1 micron in thickness, of chemically-inert non-sticky synthetic resins or plastics, which constitute dry lubricants.  Specified coating materials include polysiloxane resins, modified, e.g. benzylated phenoplasts, polyethylene resins, polyvinyl chloride resins, aminoplasts, furan resins, polyesters, polyamides, polyurethanes, ethoxylin resins, polystyrene, polyvinylcarbazole, polyvinylidene chloride, polychlorofluorocarbons, polyvinyl acetate, alcohol, formal, acetal and butyral, polyacrylonitrile, polyacrylic esters, polymethacrylic esters, aldehyde resins, ketone resins, cellulosic esters and ethers, and polyfluorocarbons.  Other lubricating substances such as graphite and molybdenum disulphide may be added.  Specified methods of application include (1) dusting with a powder of the plastic, followed by sintering under elevated pressure; (2) rubbing e.g. by rumbling with a powdered plastic in a rotating cylinder, followed by sintering; (3) applying the plastic by rolling; (4) dipping in, or spraying with, a solution or dispersion of the plastic, drying, and, if desired, sintering. Silicone resins may be applied by moistening the components and subjecting them to the action of organohalosilane vapours. Ultrasonic vibrations may be applied during coating, e.g. during immersion in a bath of polytetrafluoroethylene dispersion.  The invention is particularly applicable to the coating of mainsprings, but such parts as levers and pallet wheels, toothed wheels, spindles and bearings may also be treated.

Patent GB-774751-A (GB)
Title: Improvements in the production of concentrated formic acid from formates
IPC: C07C51/02
Filed: 1955-06-21
Abstract: Concentrated formic acid is obtained by the decomposition of formates by means of a mineral acid, especially concentrated sulphuric acid, by suspending the solid formate in an inert liquid which is not miscible with formic acid and which has a boiling point higher than that of formic acid, adding the mineral acid to the suspension and distilling off the formic acid as an azeotrope with the inert liquid. Specified inert liquids are 2-methyl heptane, 3-methyl heptane, n-octane, cumene, tetrachlorethane and perchlorethylene.  It is advantageous to use liquids having a specific gravity of between 1.3 and 1.8 preferably between 1.5 and 1.8.  In an example a stream of concentrated sulphuric acid is allowed to flow into a stirred suspension of sodium formate in perchlorethylene.  The temperature rises to 85 DEG  to 90 DEG  C. and an azeotropic mixture of formic acid and perchlorethylene distils over.  After all the sulphuric acid has been added the reaction mixture is heated and a mixture of formic acid and perchlorethylene corresponding to the partial pressures distils over.  The condensed vapours form two layers, the upper layer comprising formic acid being recovered whilst the lower perchlorethylene layer is returned continuously to the reaction vessel.

Title: Improvements in or relating to apparatus for, or a method of dispensing sheet material
IPC: A47K10/28
Filed: 1945-07-13
Abstract: 608,601. Towelling &c. dispensers. STEINER SALES CO. July 13, 1945, No. 17917. Convention date, July 14, 1944. [Class 18] In a device for dispensing towelling or other sheet material, means are provided for releasing a stop mechanism so that a number of lengths can be drawn off successively, and then for preventing release of the towelling until the end of a predetermined time. The towelling is pulled by hand around a pinch roll 14 and measuring roll 7, and the stop mechanism comprises a lever 23, one end 26 engages a shoulder 22 on a disc 21 carried by the roll 7. When the pull on the towel is released a spring rotates the roll 7 and disc 21 backwardly so that a pin 33 on the disc engages a stop member 34 and releases the lever 23 from the shoulder 22 so that a further length of towelling can be pulled from the supply. The lever 23 can be held in locking nosition to restrain movement of the roll 7 by a spring arm 50 carried by a shoe 47 which also supports the movable member 49 of a vacuum device 41, 49. The device 41, 49 forms the timing control for the lever 23 and is provided with an adjustable needle valve 58 by which the time during which towelling cannot be taken can be controlled. The vacuum device is closed by a piston 56 sliding in a cylinder 57, also having an adjustable needle valve 58, and the piston is raised when towelling is pulled down from the supply by a pawl 62 engaging one of a number of notches 63 in the piston. The pawl 62 is pivotally mounted on a slide 61 secured by a link 31 to a crank pin 30 on the disc 21. The number of notches 63 and the stroke of the slide 61 determine the number of consecutive releases of the stop mechanism prior to the engagement of the arm 50 with the lever 23 and the bringing into operation of the timing device 41, 49.

Title: Improvements in or relating to electric sawtooth wave generator circuits, time-base circuits and the like
Inventor: SKOYLES DEREK ROBERT
IPC: A22C7/00
Filed: 1955-06-21
Abstract: 821,517. Converting. MULLARD RADIO VALVE CO. Ltd. Aug. 31, 1956 [June 21, 1955], No. 17917/55. Class 38 (2). [Also in Group XL (c)] A D.C. voltage for external use is provided by a circuit in which a sawtooth current is generated in an inductance by charging a capacitance during the forward stroke, discharging it through the inductance and a transistor during the flyback and then permitting the energy in the inductance to discharge at a constant voltage during the next forward stroke. In Fig. 3, a capacitor 61 is charged resonantly from the H.T. supply during the forward stroke through an inductor L2, a diode D2 being provided when necessary to prevent the capacitor discharging through the supply. At the end of the forward stroke a synchronizing pulse applied to the base of a transistor T renders the transistor conducting for a sufficiently long period for the capacitor to discharge resonantly through an inductor L1. The current in the inductor accordingly rises to a peak whereupon the voltage across its terminals reverses and a linear discharge commences through a diode D1 and a substantially constant voltage source V, so producing the forward stroke and charging the capacitor C2 in the source. The voltage across this capacitor may be used in an external circuit. In an alternative circuit operating in a similar manner (Fig. 2, not shown), the positions of the capacitor C1 and transistor are interchanged. The transistor may be operated in an avalanche manner. This may be effected either by causing the input pulses to pass the base voltage through a value at which avalanche multiplication occurs or by applying the pulses through a blocking capacitor to the collector so that the collector potential is suddenly brought to a sufficiently high value to initiate avalanche multiplication. Preferably, the base is simultaneously biased in the forward direction by regenerative reaction between the collector and base. A rectifier connected between the inductance L1 and the junction of the collector and blocking capacitor will prevent the synchronizing pulses discharging through the inductor. A capacitor may be connected between collector and base to improve the avalanche operation. Specification 642,910 is referred to.
