Abstract: 439,677. Watches. MEYER & STUDELI SOC. ANON., Weissensteinstrasse, Soleure, Switzerland. May 7, 1934, No. 13751. Convention date, May 8, 1933. [Class 139] In a self-winding wrist watch wherein the mainspring is coupled to an oscillatory weight pivotally mounted near the periphery of the substantially rectangular movement, the weight is shaped like a shallow cup substantially enclosing the movement. The movement 2 is carried by a movement plate 1, Figs. 1, 2, to which the oscillating weight 5 comprising a bottom plate 19 and side walls 191 surrounding the movement is pivoted at 4. A bridge 7 secured to the movement block 2 is located in an aperture 6 in the plate 19, and houses a ratchet wheel 8 which drives the mainspring ratchet 12 through gearing 10, 9, 11, 12. Pivoted coaxially with the ratchet wheel 8 is a lever 13 which carries a spring pressed driving pawl 14 and is oscillated by the weight to wind the mainspring through a blade spring 16 fixed at one end to the plate 19 and at its other end engaging between the arms of a fork 15 rigid with the lever. A stop pawl 18 prevents backward rotation of the ratchet wheel 8 and the blade spring 16 is adapted to yield against the reaction of the mainspring when the latter is fully wound to prevent overwinding. The Specification as open to inspection under Sect. 91 also describes other embodiments. In one the moving weight 24, Fig. 3 (Cancelled), is pivoted at 23 to the plate 20 carrying the movement 21, and the driving pawl 28, pivotally mounted on the weight 24, rotates a ratchet wheel 29 geared to the mainspring ratchet 33. In a modification of this embodiment the driving pawl 35, Fig. 5 (Cancelled), is mounted on a slide 36 engaging in a slot 37 in the moving weight and a spring 38 normally maintains the slide at the upper end of the slot. When the mainspring is fully wound however, the spring 38 yields and the slide oscillates in the slot 37. In another embodiment, the driving pawl 41, Fig. 6 (Cancelled), is mounted on a lever 39 rotatably mounted coaxially with the ratchet wheel 29, the lever having a fork 42 engaging a pin 51 on the moving weight 24. The pin 51 may be rigid or it may be adapted to yield to prevent overwinding. In Fig. 7 (Cancelled), the driving pawl 45 is mounted on a lever 43 pivoted at 44 to the movement 21, and similarly rocked by a pin 51. In a further embodiment the pivotal lever carries two driving pawls to advance the ratchet in both directions of movement of the oscillating weight. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to thermionic tube circuit arrangements
Inventor: CROWTHER GERALD OFFLEY
IPC: H03F3/52
Filed: 1955-05-13
Abstract: 769,169. Pulse amplifying circuits. MULLARD RADIO VALVE CO., Ltd. May 13, 1955. No. 13897/55. Class 40(6) The Figure shows a cathode-follower stage 1 in which when a negative-going step-wave is applied at input 5 to its control grid the fall in voltage at the cathode is limited by the time constant of the network 9, 10 where 10 is the stray capacitance associated with the cathode load resistor 9. Discharge-tubes 12 and 19 form a conventional flip-flop circuit in which in the stable state, tube 12 is cut-off and tube 19 conducting. When a negative pulse is applied at input 5 a negative voltage is produced across resistor 9 and stray capacitance 10 commences to discharge, simultaneously the flip-flop is triggered to its unstable state by the voltage across load 9 so that tube 12 conducts and passes a substantial current to discharge stray capacitance 10. Preferably the fall of voltage is such that cathode 8 just follows grid 4. After a period determined by the constants of the circuit the flip-flop reverts to its stable state and the circuit is ready to receive a further input signal. Instead of a flip-flop a trigger circuit based on the blocking oscillator or transitron may be used. Specification 708,169 [Group XXXV] is referred to.

Patent GB-711545-A (GB)
Title: Improvements in or relating to dull lacquers
IPC: C09D161/20
Filed: 1951-06-14
Abstract: A lacquer comprising a urea-formaldehyde or melamine-formaldehyde lacquer resin, an alkyd resin, and cellulose nitrate in a solvent medium is subjected to conditions promoting further condensation of the resins, if desired in the presence of a catalyst, until a dulling effect is imparted to the lacquer. The further condensation may be promoted by heating the lacquer, and if an acid catalyst is present, the reaction may be stopped by adding a neutralizing agent.  As catalyst, there may be used hydrochloric acid in alcohol solution, phosphoric acid, oxalic acid, or zinc chloride.  Triethanolamine may be used for neutralizing the catalyst.  In an example, a clear lacquer consisting of a castor oil modified non-drying alkyd resin, urea-formaldehyde resin, cellulose nitrate, and a solvent mixture of xylol, butyl acetate, ethylene glycol, and ethyl alcohol is prepared and to it is added a catalyst preparation comprising hydrochloric acid and phosphoric acid dissolved in alcohol.  The lacquer is left to stand for 3-4 days at room temperature to allow condensation of the resins to proceed until the lacquer has a paste-like consistency. It is then neutralized with a solution of zinc stearate in toluene. This lacquer may be mixed with a clear cellulose lacquer to produce a lacquer of the desired dulling effect.  In another example, a lacquer comprising oil-modified alkyd resin, urea-formaldehyde resin, cellulose-nitrate, and solvent, is mixed with a solution of hydrochloric acid in an organic solvent.  The mixture is heated to 100 DEG C. and maintained at that temperature for several hours while being stirred.  On cooling, the lacquer is of a pasty and slightly grainy consistency.  It is pulverized and then mixed with a clear lacquer to form a lacquer of the desired dully effect.  Specification 711,543 is referred to.
