Filed: 1973-07-11
Abstract: 1386719 Treated ethylene/acrylic films; laminates GULF RESEARCH & DEVELOPMENT CO 11 July 1973 [12 July 1972] 32988/73 Headings B5B and B5N A film formed from a copolymer of ethylene and acrylic and/or methacrylic acid is treated to convert at least a portion of the surface carboxyl groups to salt forms, which preferably contain a cation derived from a Group I, II or III element, ammonia or an organic base. The treatment which is preferably with sodium or potassium hydroxide renders to film more suitable for use in the construction of laminated windscreens. In examples an ethylene/ acrylic acid copolymer is used to form a film which is treated with potassium hydroxide to convert the surface carboxyl groups. The films thus obtained were laminated between two sheets of window glass 3 mm. thick by pressing the sheets at 135‹ and 107‹ C. at a pressure of 14 kg./cm.<SP>2</SP>.

In an electrically heated iron, timing means is wound up by movement of the iron in use which deenergizes the iron after an interval when it is left unused but switched-on. As shown, the iron is heated by a spiral element 2 controlled by temperature regulator 5 comprising a bimetallic strip 7 operating through a plunger 8 on a snap action spring 9. The circuit of elements 2 is completed by contacts 11a, 12a on springs 11, 12 which are clamped at one end. The free end of spring 12 is connected, through an omega spring 13, with a spring 14 whose free end 14a engages a ratchet wheel 15. Wheel 15 is biased anti-clockwise by a spring which is wound up by a pendulum 17 operating, when the iron is in use, through an escapement. If the iron is left switched on and stationary, wheel 15 runs down until the edge 15b of the next tooth engages end 14a so that eventually spring 13 snaps over and separates contacts 11a, 12a. The element 2 can not be re-energized until end 14a is disengaged.

Title: Improvements in or relating to method of and apparatus for making cellular rubber articles
IPC: B29C35/12
Filed: 1947-12-17
Abstract: Cellular rubber articles are made by frothing an aqueous dispersion of a vulcanizable rubber, gelling the froth in the desired shape, subjecting the wet gelled froth to a high-frequency electrical field to vulcanize the rubber, and thereafter drying the article.  In an example, an aqueous dispersion of sulphur and zinc diethyl-dithiocarbamate was added to a concentrated natural latex and then zinc mercaptobenzthiazole added to form a master batch.  Part of this master batch was stirred and the following ingredients added in the order named:-piperidinium pentamethylene-dithiocarbamate, potassium salt of castor oil, potassium oleate, zinc oxide, and sodium silicofluoride, after beating, the mix was poured into moulds and vulcanized at approximately 212 DEG  F. by high-frequency heating, as described (see Group XI).  When neoprene latex is used, the foamed mass is heated to approximately 300 DEG  F.  Other synthetic rubbers which may be used are copolymers of butadiene with styrene or acrylonitrile, polybutadiene and butyl rubber.

Abstract: 464,652. Fluid-pressnre servomotorcontrol systems. MORRIS INDUSTRIES, Ltd., and DAVEY, B. A. Dec. 4, 1935, No. 33580. [Class 135] A piston b operating a throttle or like valve for controlling the fuel supply to an internalcombustion engine according to changes in barometric, induction pipe or other variable fluid pressure has a control valve d of piston form which allows the operating liquid to pass it continuously and has enclosed diaphragms or pistons attached to its ends for balancing extraneous forces. The valve d has three annular grooves f, g, h the valve parts between which are of less width than passages n, o leading to opposite sides of the piston b so that in the intermediate position shown a liquid such as oil can pass freely from an inlet through the grooves f, g, h and openings j, k to a passage l communicating with an outlet m. A spring g presses the valve d against a barometric device p exposed to the variable fluid pressure existing-in a chamber v. The ends of the valve d pass into chambers r, s closed by diaphragms t, u or pistons attached to the valve. The adjacent sides of these diaphragms or pistons are exposed to the pressure in the passage l whilst their, remote sides are under the pressure in the chamber v, a passage w enabling this latter pressure to act on the diaphragm t. The effective forces acting on the valve are therefore those due to the spring q and the barometric device p. Specification 447,198 is referred to.

Abstract: 1473420 Fluid-pressure control circuits PEINER MASCHINEN UND SCHRAUBENWERKE AG 30 July 1974 [31 July 1973] 33652/74 Heading F1P In the circuit shown, Fig. 1, actuators 15, 16 are supplied by a reversible pump 1 and liquid is returned to or withdrawn from a reservoir 26 as required to compensate for the difference in volume between the chambers on opposite sides of the pistons. Assuming that the pump is acting to supply liquid to chambers 11, 12, through lines 4, 9, the return path from chambers 13, 14 is blocked by check-valves 45, 47. The resultant rise in pressure in the line 4 opens the pilot-controlled check-valve 47 through a pilot line 49. This allows liquid to return through a line 50 and a check-valve 51 to the pump, the excess flowing through a filter 34 to the reservoir. If the supply from the pump is reversed, pressure in a line 32 opens a pilotoperated check-valve 52 through a pilot line 44 so that the return from chambers 11, 12 can flow to the pump through lines 9, 4. The extra liquid required is drawn from the reservoir through a valve 2. Relief valves 6, 36 are provided. The valves 47, 52 are hydraulically locked by supplying pilot pressure to both sides of the operating piston through lines 48, 49 and 43, 44 respectively. Fig. 2 shows an embodiment in which liquid from chambers 11, 12 flows through a pilot-controlled checkvalve 27 and lines 29, 28, 17 directly to the chambers 13, 14 without going through the pump. Extra liquid is drawn from the reservoir as before. Return from chambers 13, 14 is as described with reference to Fig. 1.

[A Specification was laid open to inspection under Sect. 91 of the Acts, July 26, 1948.] Class 38 (iv). A system for automatically controlling the speed of a motor-alternator in response to alternator frequency is rendered effective by means responsive to motor input voltage. To maintain constant the frequency of a threephase alternator 2 driven by a D.C. motor 1, a rectifier 18, supplied in series with an ironcored inductance 37 from one phase 25, 26 of the alternator output, energizes the operating coil 15 of a carbon pile regulator 9 in series with the motor shunt field winding 7, while, to maintain the alternator voltage constant, a rectifier 49, supplied from the same phase of the alternator output, energizes the operating coil 46 of a carbon pile regulator 40 in series with the alternator field winding 24. The frequency control is naturally voltage responsive and a condenser 52 included in series with the supply to rectifier 49 makes the voltage control frequency responsive, the senses of these secondary effects being such as to produce stable voltage and frequency. To cut out frequency control during starting a relay 33 is insufficiently energized from the lowered voltage of a battery 6 supplying the motor so that relay contact 31 short circuits carbon pile 9 and disconnects the supply from rectifier 18, but, when the motor is up to speed, rise of battery voltage causes changeover of contact 31 to introduce frequency control.
