Title: Improvements in or relating to the production of articles from highly polymerised substances
IPC: C08F291/00
Filed: 1937-07-08
Abstract: Mechanically shaped, especially extruded and moulded, articles are obtained from highly polymerized substances, i.e. solid and tough polymerizates, by first adding to the highly polymerized substance a monomeric or slightly polymeric polymerizable substance which is freely liquid or of a viscosity insufficient to render it self-supporting in shape, next working up and mechanically shaping the mixture, and then submitting the shaped mass to a final polymerization treatment.  Polymerization accelerators and small quantities of unpolymerizable softening agents may be added to the mixture.  In examples: (1) a solid, tough polyacrylic acid ester is swelled with about 25 per cent of a viscous monomeric or slightly polymeric ester, e.g. vinyl acetate, isobutylene, acrylic acid methyl, ethyl, or butyl ester, extended to form a shaped article and the latter finally polymerized in a mould at 70-80 DEG  C.; (2) tough natural or synthetic rubber is admixed with a liquid butadiene polymerizate, shaped and finally polymerized during vulcanization; (3) a solid, tough polyacrylic acid ester is mixed with about 20 per cent of liquid, slightly polymeric styrol and finally polymerized at about 120 DEG  C., after extrusion.ALSO:Mechanically shaped articles are obtained by mixing rubber with a monomeric or slightly polymeric polymerizable substance which is liquid or of a viscosity insufficient to make it self-supporting in shape, shaping that mixture, e.g. by extrusion, and finally submitting the shaped mass to a final polymerization treatment. Polymerization accelerators and small quantities of unpolymerizable softening agents may be added to the mixture.  In an example (2) tough natural or synthetic rubber is admixed with a liquid butadiene polymerizate, shaped and finally polymerized during vulcanization.

Abstract: 478,251. Dynamo mountings. LUCAS, Ltd., J., and HUYTON, A. July 14, 1936, No. 19517. [Class 35] A dynamo is angularly movable on a spindle carried by a bracket on a cycle frame, the bracket also carrying a spring-controlled pawl co-operating with a ratchet fixed to the dynamo and a finger lever is provided to control the engagement of the pawl and ratchet. In the form shown, the dynamo c is held in the inoperative position by the engagement of pawl with the tooth h of the ratchet g. When the lever k is moved away from the left-hand stop l its cam surface m removes the pawl from notch h by pressure on the pawl projection n and a spring coiled about the fixed spindle b and disposed in the generator casing then moves the dynamo into engagement with the tyre f. The movement of the dynamo is limited by the engagement of the pawl in the second ratchet slot i. Pressure of the lever k on the left-hand stop l rocks the dynamo about its pivot and returns it to the inoperative position.

Filed: 1972-04-27
Abstract: 1369742 Power boost mechanism for brakes DEUTSCHE BENDIX AUSRUSTUNGS GmbH 27 April 1972 [25 May 1971] 19677/72 Heading F2F A power boost mechanism for an hydraulic braking system comprises a servo-valve member 26 movable in a valve housing 40 for controlling a variable working fluid pressure acting on an output piston 82 which is sealingly received in a working chamber 76 of an output servo-motor housing 72. The servo-valve member 26 is responsive to a control pressure of an incompressible fluid contained in an enclosed control chamber 84, and actuated thereby, the control pressure varying as a function of the displacement in the chamber 84 of an input plunger 90 and of an output plunger 88 connected or operatively connected to the output piston 82. In the construction shown the servo-valve member consists of a spool and the housing 40 has ports 22, 28 and 38 for connection to a power steering pump 12, a power steering gear 14 and a reservoir 34 respectively. In the rest position of the valve member 26 fluid pressure from the pump 12 passes to the power steering gear 14 through a groove 24 in the valve member, the working chamber 76 being vented to the reservoir 34 through holes 56 in the valve member. On actuation of the valve member 26 flow through the groove 24 is throttled further, holes 58 in the valve member are uncovered and pressurized fluid from the pump flows through the holes 58 and into the working chamber 76 to actuate the output piston 82. As shown the output piston 82 is intended to be connected to the piston of any type of master cylinder by a push rod 100. However output piston 82 may form the piston of a master cylinder or a piston of a tandem master cylinder. The servo-valve member 26 is provided with a relief valve, a valve member 62 of which opens should the servo-valve member fail to move to allow fluid to bleed from the control chamber 84 and allow the input plunger 90 to operate directly the output plunger 88. If the pump 12 fails the servo-valve member 26 will be operated but fluid will pass through the relief valve and into the working chamber 76 until the input plunger engages the output plunger. In a further embodiment the servo-valve and servo-motor are formed as an integral assembly, the output plunger passing through the servo-valve member to engage the output piston (Fig. 2, not shown).

Abstract: 651,392. Impedance networks. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 2, 1946, No. 19710. [Class 40 (viii)] [Also in Group XL (c)] A band-pass circuit, forming one of a number of stagger-tuned coupling circuits, is arranged to pass a broad band of video signals and to cut off sharply at the frequency of the audio carrier. Fig. 1 shows a coupling between R.F. amplifying valves 1, 2, comprising a parallel resonant circuit 5, 6-the capacitance 6 being provided by the stray capacities of the valves- and a series-resonant circuit 3, 4, which is tuned to the audio carrier frequency. The circuit 5, 6, is tuned so that the whole circuit 3, 4, 5, 6 acts as a parallel resonant circuit at a frequency just above that of the audio carrier. The inductance 3 is large and the capacitance 4 small compared with the inductance 5 and the capacity 6 respectively. In a modification, Fig. 3, the circuit 3, 4 is connected to a tapping on the inductance 5, and the audio carrier signal voltage developed across condenser 4 is taken off by lead 7 to a separate amplifier via condenser 11. In further modifications, Figs. 4 ... 6 (not shown), the lead 7 is connected to the junction between condenser 4 and a further condenser interposed in the earth lead, or the position of components 3, 4, is reversed and the lead 7 connected either to their junction or to a tapping on the inductance. In further modifications, Figs. 9 ... 11 (not shown), a parallel resonant circuit corresponding to 5, 6 of Figs. 1 and 3 is retained, but various further parallel resonant circuits tuned to the audio carrier frequency replace the series-resonant circuits. Specifications 514,064 and 516,252 are referred to.
