Title: Improvements in adhesive transfers and in the manufacture thereof
IPC: B44C1/16
Filed: 1966-03-15
Abstract: 1,115,805. Transfer. J. F. SIMPSON, and R. D. SIMPSON. 15 March, 1966 [15 March, 1965; 17 June, 1965], No. 11253/66. Heading B6C. A transfer comprises a back sheet of blotting paper, a water-soluble release coating on the forward face of the back sheet, a transferable film on the forward face of the release coating and a coating of contact or pressure-sensitive adhesive on the forward face of the transferable film. A water-permeable pre-coat of size or filler, e.g. cooked starch may be formed on the forward face of the back sheet below the release coating. In a preferred form the precoat and/or release coating cover that area of the base sheet below the transferable film and project only marginally, if at all, beyond the edges thereof. The adhesive coating then covers the face of the transferable film and projects only marginally, if at all, beyond the edges thereof. A non-adhering removable cover sheet, e.g. silicone coated paper may protect the pressure-sensitive adhesive layer until the transfer is used. The transfer is produced by lightly adhering a sheet of blotting paper to a rigid mounting plate, e.g. with an adhesive of cooked starch, clay and water, and forming on this sheet successive superposed layers of a pre-coat (starch), a release coating (e.g. potato gum and water with small amounts of glycerine, a non-ionic detergent and methylated spirits), a transferable film and a pressuresensitive adhesive. The coatings of size, release coating, transferable film and adhesive may be applied to the back sheet using a nylon or wire screen. The transfer is applied by securing it to a receiving surface by means of the pressure-sensitive adhesive while the back sheet is dry, applying water to the rear face of the back sheet to dissolve the release coating and then removing the back sheet.

Title: Improvements in and relating to pulse radar equipment

Filed: 1946-04-12
Abstract: 610,664. Wave-guides; impedance networks. BLACK, D. H. April 12, 1946, No. 11359. [Class 40 (viii)] [Also in Group XL (c)] In a pulse radar system employing a rotating aerial system having two directions of maximum reception providing two sets of receiver signals which are equal when the reflecting object lies on a bearing midway between the two directions, means for obtaining the sum and difference of the two signals and passing the sum to an indicator only when the difference is below a certain magnitude comprises two independent wave-guide feeds 2, 3 of substantially equal length, terminating at the ends remote from the aerial at points A and B one-half wavelength apart on an endless annular guide 1 which has an electrical length of 3#/2. The output from a guide 4 connected at point C midway between points A and B represents the sum or difference of the input signals, depending on the relative polarities of these at points A and B, while the output from guide 5 connected at point D, spaced #/4 from point B, similarly represent the difference or sum of the input signals. An alternative to the annular waveguide shown is a hybrid-T, Fig. 2 (not shown), the two input signals being applied to the ends of the straight section while the difference signals are obtained from the series-T junction and the sum signals from the shunt-T junction. For lower frequency operation an annular structure of coaxial feeders may be employed.

Abstract: 346,993. Weighing - apparatus for feeding testile fibres. KERSHAW, A., 24, Moseley Avenue, Seedfield, Bury. April 16, 1930, No. 12002. [Class 143.] In a weighing mechanism for automatic hopper feeding machines for textile fibres, a portion of each trunnion of the scale pan is in the form of, or carries, a knife-edge which rests on the bottom of a transverse V-shaped groove or slot in the scale arm, or in a link depending therefrom during the filling of the scale pan, and the frame of the machine carries fixed bearings to receive the cylindrical portions of the trunnions and to support the scale pan after recovering its charge, so that after subsequent depression of the scale arm by cam or other mechanical means the V-shaped groove is removed from contact with the knifeedge, and the. pan may then be rotated on its trunnions to discharge its contents. The knifeedged trunnions a of the scale pan A are supported in V-shaped grooves in 'the scale beam B or, as shown, in blinks B<1> slung from the beam. When the requisite weight of fibre has entered the pan the feed thereto is cut off by the downward movement of the pan, and the cylindrical part of the trunnions descends on to stationary bearings C. A cam-operated hook f descends and pulls down the end of the beam, thus leaving the trunnions entirely supported in the stationary bearings, and a hook H operated by a runner e<1> holds down the trunnions whilst the usual rack-and-pinion gear inverts the pan to discharge its contents. A spring K cushions the downward movement of the beam. An adjustable weight W is mounted on the beam in the usual manner or may be suspended by a pair of links with knife-edged bearings.

Radio interference from a source S is measured at a receiver E in a chamber 1 and the chamber side-walls or lateral boundaries of the path between the source Sand receiver E are covered with radio wave absorbing material 3 to prevent reflected energy affecting the measurements. Moreover, the chamber ends behind the source S or receiver E may be parabolic or ellipsoidal surfaces of revolution or cylinders to focus radiation on them only towards the receiver E, and in addition a reflector in front of the source S and/or receiver R may prevent direct transfer of radiation, or the end walls may only have wave-absorbing material. The absorbing material may be applied on to acoustic absorbing material or may be graphite or other material impregnated in the sound-absorbing material, the latter having conical projections. It may be in several layers of varying conductivities. The chamber walls may be adjustable and the chamber 1 may be vertically located in a staircase well.

Abstract: 559,254. Floating toys. STANTON, J. A. Aug. 31, 1942, No. 12237. [Class 132 (iii)] A toy comprises a floatable vessel having an aperture below the water line, means controlled by the striking of a target on or in said vessel for uncovering or opening said aperture and allowing water to enter said vessel and cause it to become wholly or partially submerged, and float-controlled mechanism in the hull of said vessel adapted to produce subsidiary effects as said vessel becomes submerged and said float is caused to rise. As applied to a toy submarine, when a target 10 is hit, a rod 12 uncovers an aperture 11 and water enters the hull. Float 20 rises to rock bellcrank 17 whereby trap-door 14 is released and springs open, and as the float rises further, a spring 21 is released to project objects such as figures 24 out of the conning tower. A water-tight compartment 5 causes the submarine to sink by the stern. The vessel may be propelled by a motor, which is braked by the upward movement of the float. The upward movement of spring 21 may launch a life-boat.

Articles, e.g. soles and heels, are moulded from rubber or thermoplastic material by compressing the material in a three-part mould under the action of pressing mandrels, air being driven out through microscopic apertures provided on the contacting faces of the mould parts, the top part of the mould then being opened and the finished article pushed out of the bottom and intermediate parts by the pressing mandrels and seized by fork members and pushed into a magazine. The mould comprises a top part 24 slidably engaged in guideways 23 under a tiltable top heating plate 22, an intermediate part 19 connected with a bottom part 17 which is slidably engaged in guideways 15 on a bottom heating plate 14, a piston-controlled lifting table 5 fixed to the plate 14, and piston-controlled pressing mandrels 8 passing through this plate. With the lifting table 5 and pressing mandrels 8 in their lower position and the top heating plate 22 tilted outwards, a rough blank of the raw material is placed on a relief 20 provided in the intermediate part 19 and the mould closed. The pressing mandrels 8 are then raised into the material until this completely fills the closed mould. In this condition the material, if rubber, is vulcanized. After opening the mould the pressing mandrels 8 are raised to push the finished moulding 40 out of the intermediate and bottom parts of the mould and a fork member 35 is moved into position beneath the moulding so as to catch them when the mandrels are withdrawn. Finally the fork member 35 is moved clear of the mould and the machine is ready for receiving new blanks. The mouldings 40 remain on the fork member but when the latter is again returned to the mould, they are pushed by a spring-loaded pivoted ledge 39 into a magazine 41.
