Title: Improvements in and relating to systems operating by means of wave trains
IPC: G01S15/34
Filed: 1944-06-09
Abstract: 604,429. Radiolocation. HUGHES & SON, Ltd., H., SPROULE, D. O., and HUGHES, A. J. June 9, 1944, No. 11108. [Class 40 (vii)] [Also in Group XXXVIII] In a pulse radar system the reflected wave train is rendered distinguishable from random disturbances by increasing its amplitude relatively thereto, with consequent reduction in duration, by " slurring " its initial frequency (Fig. 2) and applying the combined " noise " and wave train oscillations to dispersing means in which the velocity of propagation depends upon the frequency, so that-the elements of the wave train coalesce (Fig. 3) and appear, relatively to the " noise," with an enhanced intensity. The dispersing effect may be obtained by using wave-guides of suitable dimensions.

Title: Process for obtaining cured or curable masses containing a low percentage of polyester resin and product obtained by said process
IPC: C08K3/00
Filed: 1963-03-20
Abstract: Cured or curable masses containing from 3 to 35% by weight of polyester resin are prepared by adding a catalyst to a homogeneous liquid mixture of an unsaturated polyester resin dissolved in a copolymerizable monomer, and mixing under vacuum a dried inert substance and said catalyst-containing liquid until a pasty and hydrorepellent mass is obtained.  The mass obtained is essentially composed of polyester resin, inert filler, pigments, catalyst and other additives which may be added to the mass in the form of inserts.  The inert fillers which may be mineral, metallic, vegetable or synthetic materials in fibrous, powdered or granular form used in the examples are powdered marble and metallic fillers.  If the desired thickness of the final product is 1.5 cm. or less, the treated mass formed after mixing under vacuum is passed through an extruder in order to preform it and the preformed mass is poured into moulds which have been heated to 105 DEG  to 110 DEG C.  The moulds are then subjected to vibration to eliminate any air between the mould and the conglomerate surfaces. To effect polymerization it may then be necessary to place the moulds in a stove.  If the thickness of the material is greater than 1.5 cms. the mass is poured directly into cold moulds which may be heated if necessary to hasten the polymerization.

Title: Improvements relating to preserving foodstuffs in containers
IPC: A23L3/10
Filed: 1940-07-04
Abstract: 543,090. Polyvinyl chloride compositions ; packing ; closures. ENGEL, W. July 4, 1940, No. 11239. [Class 2 (iii)] [Also in Group XVII] A process of hermetically sealing foodstuff, e.g. fruit or vegetables, in a container formed by, or the mouth of which is closed by, a flaccid homogeneous shell of polyvinyl chloride plasticized with a non-toxic plasticizer, consists in subjecting the container, or container-closure, to the action of boiling water and subsequent cooling. Suitable plasticizers are phthalates and citrates, e.g., dimethylglycol phthalate or dibutyl citrate. When used as a closure, the sheet is stretched over the mouth of the container and tied with string, the heating during the sterilization causing the sheet to soften and conform to the shape of the mouth of the container, in which shape it sets upon cooling. When used as a container, the borders of the sheet are gathered together and enwrapped with string, the gathered-in borders softening and sealing during the heating. Specifications 422,957, 478,965, 483,657 and 499,931 are referred to. According to the Provisional Specification the sheet may be formed of any thermo-plastic resin plasticized with a non-toxic plasticizer.
