Title: Improvements in or relating to the manufacture of vulcanized cellular rubber and of vulcanisation accelerators therefor
IPC: C08L21/00
Filed: 1936-08-25
Abstract: Vulcanization accelerators with a low curing temperature for use particularly in connection with the production of sponge rubber are produced by the reaction of a secondary amine, an aliphatic carboxylic acid and carbon bisulphide.  This reaction product may be used as such or after treatment with a metallic salt such as zinc chloride, or corresponding salts of other heavy metals, or with an alkali metal hydroxide.  Carboxylic acids mentioned include oleic, stearic, palmitic, lauric and caproic acids.  Secondary amines mentioned include diethylamine, dimethylamine, and dipropylamine. The accelerators are incorporated into the aqueous dispersion before the foam is produced.  In an example, oleic acid is first added to an aqueous solution of diethylamine, and when solution is complete, carbon bisulphide is stirred in at room temperature.  The solution which results may be used directly by addition to an aqueous dispersion of rubber.ALSO:Vulcanization accelerators with a low curing temperature for use particularly in connection with the production of sponge rubber are produced by the reaction of a secondary amine, an aliphatic carboxylic acid and carbon bisulphide.

Abstract: 1302106 Film-flow milk coolers E LAIKE 14 May 1970 [14 May 1969] 23526/70 Heading F4S Milk is cooled by flowing it in a thin film over a cooled surface, the cooled milk collecting in a pool from which it is drained at an adjustable rate. This arrangement is combined with replaceable filter means at the milk inlet enabling the milk flow rate at the cooler inlet to be altered, and the overall cooling of the milk is thereby controlled. The drawing shows one preferred arrangement comprising a vessel 4 cooled externally by liquid jets 5. The milk is poured into a pan 1 having outlets 2 each covered by a replaceable throw-away filter (not shown). From the outlets 2 the milk is cooled as it flows in a film down the inner wall-surface of the vessel 4 and collects in a pool at the bottom of the vessel where there is a flexible outlet tube 11. By forming a U-bend in the tube 11 and raising or lowering the level- 12 of said bend, the depth of the pool, cooled film area, and the rate of draining, may be varied. By changing the filters in the pan I to filters of different mesh, the inlet flow rate may be altered. The wall of the vessel 4 may be corrugated to provide an unduing flow path for the milk. One or several of the vessels 4 may be detachably mounted in a heatinsulated container 9 from which there is a coolant drain 8.

Title: Improvements in reversing mechanism
IPC: F16D33/00
Filed: 1937-08-27
Abstract: 501,365. Hydraulic transmission of power; washing - machines; motors. SINCLAIR, H. Aug. 27, 1937, No. 23576. [Class 69 (ii)] [Also in Groups VIII and XXXVII] In reversing mechanism of the kind in which a driven member having substantial inertia is required to be moved continuously in one direction for a limited period, brought to rest, immediately moved in the opposite direction, after a limited period again brought to rest and immediately moved in the original direction, this cycle of operations being repeated, the driven member is driven by a reversible driving motor through a hydraulic coupling of the kinetic type. As applied to a laundry washing machine, the rotatable receptacle containing the articles being washed is oscillated by a squirrel-cage electric motor 17 driving it through a Vulcan- Sinclair traction type coupling, as described, e.g. in Specification 385,086, and reduction gearing 12, 13, 14, 15. A reversing switch 24 for the motor has a control lever 25 actuated by solenoids 26, 27, alternatively rendered operative by a two-way toggle switch 32 thrown over by a stud 33 on a worm-wheel 34 meshing with a worm 35 on the shaft 16. Lever 25 is connected by a lost-motion device 38 to an adjustable dashpot 36; the lever 25 is thus movable quickly to its neutral position in which the motor is de-energized, but its further movement to the " forward " or " reverse " positions is delayed by the dashpot. In operation, when the motor is de-energized, the motor and the receptacle continue to rotate owing to their inertia ; the damping imposed on the receptacle by its contents causes it to be retarded relatively more rapidly than the motor, despite its larger inertia. The dashpot 36 is preferably so adjusted that the switch 24 causes the motor to be energized by current urging it in the opposite direction before the container, and therefore also the motor, has come to rest. The arrangement is stated to result in a substantial reduction in the duration, and to a lesser degree the amplitude, of the cyclic power peaks. The invention is applicable to other kinds of apparatus such for example as drying and heat treatment machines, furnace charging machines, manipulating roll devices and conveying and process machinery.

Title: Planographic printing plate
IPC: B41N3/03
Filed: 1963-06-13
Abstract: 981,767. Printing plates. MILLEN INDUSTRIES Inc. June 13, 1963 [June 20, 1962], No. 23694/63. Heading B6C. A direct-image paper base planographic printing plate comprises a high wet-strength paper base serving as the support of said plate, a continuous microporous intermediate coating on said base consisting of from 10 to 50 parts of adhesive binder per 100 parts of mineral pigment and a continuous top coating over said intermediate coating consisting of alkalistabilized colloidal silica. The mineral pigment of the intermediate coating consists of from 20 to 40 parts of zinc oxide (all parts are by weight) and from 80 to 60 parts of hydrous clay whilst the adhesive binder is a zinc ammonia casein complex containing from 1 to 6% of zinc metal by weight of the casein. The silica particles of the colloidal silica are coated by the stabilizing alkali and have a silica to alkali ratio of from 60:1 to 130:1, the silica being deposited from aqueous colloidal dispersion at alkaline pH by treating with volatile acid, evaporating and calendering after drying. The microporous intermediate coating provides adequate " tooth " for imaged impression from a type writer with the zinc therein resisting discolouration of the unimaged portions when used as a direct-image printing master. The paper base support may be poster board primed with a coating mixture of a copolymer of butadiene and styrene with polystyrene. The microporous coating may contain 75 parts of kaolinite and 25 parts of zinc oxide combined with 25 parts of zinc ammonia casein composition as a binder, these ingredients being mixed in water to a solid content of about 25-45% prior to coating. The coating may be thinned by diluting with 10 to 12% ammonia hydroxide. The zinc compound used in the zinc ammonia casein composition may be an oxide, carbonate or cyanide. The alkali-stabilized colloidal silica is in the form of dispersed particles having a particle size of 1 to 100 millimicrons, the particles being coated by the stabilizing alkali and an average molecular weight, as determined by light scattering, of at least 500,000. The present type of colloidal silica -is described in detail in U.S.A. Specifications 2,244,325, 2,574,902 and 2,597,872 and may be prepared by passing a silicate through an ion exchange resin to remove the alkali as described in U.S.A. Specification 2,244,325. The colloidal silica top coating must be used in an aqueous acid environment in order to provide the desired adhesive bond to the zinc ammonia casein composition with the zinc oxide-hydrous clay base coating. A preferred volatile acid is acetic acid, formic acid, propionic or butyric acid. Hardening resins such as urea formaldehyde resin or melamine formaldehyde resin or mixtures thereof may be used with the colloidal silica. U.S.A. Specifications 2,346,812, 2,534,650, 2,635,537 and 2,778,301 also are referred to.

Abstract: 677,017. Electric tests. FIELDEN (ELECTRONICS), Ltd., and FIELDEN, J. E. Sept. 8, 1950 [Sept. 15, 1949], No. 23802/49. Class 37. A device for recording voltages, or other quantities which can be represented as voltages, comprises a motor-driven potentiometer arranged to deliver a voltage balancing the voltage to be measured, a galvanometer which is deflected in accordance with the out-ofbalance voltage, a variable condenser comprising a fixed plate and a movable plate attached to the moving element of the galvanometer, a capacity-sensitive circuit actuated by the variable condenser and controlling the motor driving the potentiometer whereby the potentiometer is driven to a position of balance with respect to the voltage to be measured, and a recording element attached to the driving motor. The voltage output of a thermo-couple c is balanced against that from a potentiometer R3, the difference voltage actuating a galvanometer a, the movable element of which includes a condenser plate b associated with a fixed plate d. The variable condenser thus produced, forms, together with condenser C1, a potential-divider across the grid-cathode circuit of a Hartley-oscillator valve VI, whereby, depending upon whether the variable condenser is greater or less than condenser C1, negative or positive feed-back to the grid of V1 is obtained. When positive feed-back occurs, valve V1 oscillates in alternate halfcycles-and the valve V2 is cut-off by virtue of the rectifying action at its grid producing a biasing-off voltage. Pulses of current are consequently applied to the two-phase motor m to drive the potentiometer to a position of balance and the recording pen i to a corresponding position. When the feed-back is negative, valve V1 does not conduct while valve V2 conducts in alternate oppositelyphased half-cycles whereby the motor m is driven in an opposite direction to a position of balance.
