Title: Improvements in and relating to the preparation of impregnated or medicated aggregates of water-soluble fibres and articles made therefrom
IPC: D06M16/00
Filed: 1953-08-05
Abstract: An aggregate of water-soluble fibres impregnated with one or more chemicals or other substances, more especially for medical purposes, is prepared by applying to a mass of fibres the desired substance, dissolved or dispersed in a <PICT:0765457/IV(a)/1> <PICT:0765457/IV(a)/2> liquid in which the fibres are insoluble, and thereafter treating the fibres, if initially insoluble in water, to render them water-soluble without materially affecting the substance with which they are impregnated.  Examples of fibres which are initially insoluble in water are calcium alginate and alginic acid, which may be rendered water-soluble by converting them into ammonium alginate.  An impregnated mass of water-soluble fibres may be prepared by applying to a mass of water-soluble fibres such as ammonium alginate a solution or emulsion of an impregnant such as a mixture of castor oil and ricinoleic acid in a non-aqueous liquid such as alcohol, the solvent or carrier liquid being subsequently evaporated off.  As shown in Figs. 1 and 2, a web or sliver 5 composed of teased-out impregnated alginic acid fibres is passed through a sealing bath of mercury 6 over the first set of guide rollers 7, then over the hollow rotatable unglazed pervious ceramic rollers 1 in the chamber 2 and finally over the second set of guide rollers 7 in the sealing bath 6. Gaseous ammonia is fed via the distribution pipe 10, the short branch pipes 4 and the hollow shafts 3 of the hollow rollers 1 into the interiors of these rollers.  Each roller may comprise an inner former of metal gauze or perforated metal sheet supporting on its outer surface two ceramic semi-cylinders (or a greater number of segments) attached to the former by screws and/or end-plates one such end-plate being closed and provided externally with a short solid shaft and the other with a hollow shaft 3 rotatably supported on the ammonia inlet pipe 4.  The mercury sealing bath may be replaced by two mercury seals of U-section and the impregnated fibres may be supported on an endless perforated carrier belt.  Specifications 722,629, [Group VI], and 736,595 are referred to.

Title: Force variation marker for tyres
IPC: G01M1/26
Filed: 1971-04-19
Abstract: 1310466 Testing tyres GENERAL TIRE & RUBBER CO 19 April 1971 [17 Feb 1970] 22005/71 Heading B7C [Also in Divisions B6 and G1] A point at which maximum force variation of a tyre 8 is detected by a dynamic balancing machine is marked on the tyre whilst it is rotating by marking fluid ejected from a marker head 24. Transducers 6 coupled to the shaft 4 of a load drum 2 detect the maximum force variation, indicating a tyre construction deviation, and a signal is processed by a unit 12 and passed to a marker 18 angularly spaced from the contact point between the drum and the tyre. When the point giving rise to the force variation passes beneath the marker, a solenoid 20 is briefly energized to pivot the marker head 24 towards the side wall of the tyre, the head stopping abruptly to eject fluid, supplied by hose 26, on to the tyre, de-energization of the solenoid allow the head to return to its rest position under the action of a return spring (52). If the marker should contact the tyre, it is swung away with the tyre movement in an arc so that the tyre is not damaged. Handle 56 and screw 62 co-operate with bevel gears 58, 60 to allow adjustment of the position of the marker 18 to accommodate tyres of different sizes.

Filed: 1966-05-18
Abstract: 1,145,111. Conveyers. MANNESMANNMEER A.G. 18 May, 1966 [18 May, 1965], No. 22163/66. Heading B8A. Tubing pieces from a mill 10 are moved in single file along a conveyer section A by motor driven rolls, the pieces then passing on to central portions 17.1 of driven rolls 17 in a section B. These rolls have reduced diameter end portions 17.2, 17.3. Fingers 20 may be shifted, by an air actuator (22), from the position indicated in Fig. 4 (not shown), to that in Fig. 5 (not shown), a tubing piece (P) thus being moved from roll portions 17.1 to portions 17.2 for travel along a path 15. The fingers 20 are shifted with a harmonic motion and damage to the tubing in its heated condition is minimized. The next piece (P) is transferred by the fingers 20 to the roll portions 17.3 and travels along a path 16. The speed of the pieces (P) is approximately halved since the peripheral size of the roll portions 17.2, 17.3 is approximately half that of the roll portions 17.1. A conveyer section C provides a continuation of the paths 15, 16 by means of driven rolls 25 having conveying portions 25.2, 25.3. A skid trough 28 is provided intermediate the paths 15, 16 and receives tubing shifted from the path 15 by a plurality of kickers 29 having harmonic motion. A section D comprises a number of driven shafts 35 having spiral fins (35.1), Fig. 7 (not shown), for engagement with and transport of the pieces (P). For transferring the pieces from section C to section D, cradles 37 are moved in an orbital path by motor driven cranks (41), Figs. 7-10 (not shown). Figs. 12-14 (not shown) illustrate circuitry for controlling the conveyer sections (A-D), the fingers 20 and the kickers 29. The circuits include sensing devices (53, 53a, 164) which are responsive to the heated tubing pieces.

Title: Improvements relating to systems for the automatic application of compressed air brakes for railway vehicles under the control of automatic train control apparatus
IPC: B60T7/18
Filed: 1953-08-12
Abstract: 743,033. Fluid-pressure railway brakes. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd., and SIMMONS, A. W. Sept. 13, 1954 [Aug. 12, 1953], No. 22194/53. Class 103 (1). In a fluid-pressure brake system for railway vehicles comprising a driver's brake valve 10 and a feed valve 12 connected to a main reservoir by a pipe 14, and wherein an emergency operation of the brakes is brought about, if the train should pass a stop signal, by the de-energization of a circuit controlling a magnet valve 1 governing a valve 3 which vents the brake pipe 4, service applications are brought about, if the driver does not acknowledge an adverse distant signal, by a discharge valve 5 governed by an equalizing reservoir 6, and the de-energization of a second circuit by operation of valve 15 cuts off and releases main reservoir pressure from above the pistons in valves 7 and 9. This enables pressure from the equalizing reservoir 6 to vent to atmosphere through orifice 8 and close the feed from the valve 12 to brake valve 10. The brake pipe 4 is isolated from the apparatus when the isolating cock 21 is shut. Pressure switches 16 and 18 indicate when valves 3 or 7 have operated. In two other arrangements described, the functioning of valves 7 and 9 is governed by separate magnet valves.

Title: Methods of printing or decorating the surfaces of plastic materials
IPC: H05K3/04
Filed: 1963-06-04
Abstract: 1,070,573. Printing processes; ornamenting. C. P. STUTCHBURY. June 1, 1964 [June 4, 1963], No. 22212/63. Headings B6C, B6G and B6J. The surface of a plastic material is printed upon or decorated by applying to the surface a solvent for the plastic, and a foil, the foil thus being bonded to the surface. The foil employed is a blocking foil used in hot-stamping presses and comprising a backing strip, a heat-release coating and a thin coating of foil. The foil may be of copper, aluminium, or gold, or a pigmented foil. In one method of printing with the foil, the parts of the surface of the plastic not required to receive foil are protected by a resist wax applied by an engraved plate. The foil is now dipped into a solvent for the plastic, or the solvent is applied to the plastic surface, or both, and the foil is applied to the plastic A roller is pressed over the foil, which adheres to the non-protected parts of the surface. The foil backing is now stripped from the plastic, and the wax removed by washing with paraffin. The removed backing strip with parts of the foil adhering thereto may be employed for printing a reverse image on a plastic surface. In another arrangement, the plastic surface is coated with foil using a solvent as before, and the foil is etched away to give the required print. The plastics may be warmed during the transfer operation. Instead of using a resist wax on the plastic, the pattern to be printed may be formed on the foil before transfer to the plastic surface. This may be done by applying a resist wax to the foil and etching with hydrochloric acid or with potassium hydroxide and methylated spirits, or the foil may be pressed on to an engraved plate to which adhesive has been applied. In the latter case, the foil is stripped off the backing at the non-pattern parts leaving the pattern in foil on the backing. The method may be employed for printing on cellulosic, acrylic and vinyl plastics, specific examples given being celluloid, " Perspex " (Registered Trade Mark) and " Cobex " (Registered Trade Mark), and may be used for. the printing of labels, business cards, watch faces and printed circuits. For printed circuits, gold foil may be employed and a second application may be necessary to obtain the desired thickness of metal. Paper, glass, " Formica " (Registered Trade Mark), or plastics such as polyethylene or polypropylene for which it is difficult to find a suitable solvent, may be coated with a plastic for which a suitable solvent is readily available, and then printed as described above. Mirrors may be produced by applying a coating of aluminium or gold foil to a plastic in the manner described above.

Patent GB-223067-A (GB)
Abstract: 223,067. White, A. E., (Compuling-Tabulating-Recording Co.). Nov. 15, 1923. Factory and like time recorders, card-type; time and cost, computing.-In machines having a time-driven type-wheel and means for manually resetting the type-wheel to zero, means are provided which prevent any record being taken after a second or elapsed-time record has been made, until the type-wheel has been reset to zero. The type-wheel 13, having rows of type for the elapsed time and the cost or wages, is fixed to a shaft 12 which also carries a resetting knob 36 outside the casing 10. Fixed to the type-wheel are a clock spring 17 tending to turn it clockwise and an aligning-wheel 18 carrying a pawl 19 engaging a ratchet wheel 20 on a sleeve 22 rotatably mounted on the shaft 12. This sleeve also carries an escapement wheel 21 advanced periodically by a device 23 actuated from a master clock by electromagnets 24. One recorder is assigned to each workman, job or machine and a card is inserted into a receiver 25 to rest against an abutment 26 on a lever 27. The type-wheel having been set to zero by the knob 36 the handle 28 is operated, the initial movement actuating links 39, 40 to rock an aligning-pawl 41 into engagement with the aligning wheel 18. Further movement of the handle causes a pawl 30 to engage a block 31 fixed to the shaft 20 of a hammer 32 and retract the hammer against a spring, the pawl then disengages from the block and the hammer makes the record. The tvpe-wheel is then advanced by the escapement and a cam 44 on the aligning- wheel moves off a projection on the card-abutment lever 27 so that this lever is raised against a stop by a spring 45. An elapsed-time record may then be taken at any time and will be printed below the zero record, and on the return movement of the handle 28 the pawl 30 will be engaged by a spring-pressed pivoted Lever 47 as shown in Fig. 5, this lever having been released by the upward movement of the card-abutment lever 27. Operation of the printing hammer is therefore prevented until the type-wheel has been reset to zero so as to return the parts to the position shown in Fig. 2.

Abstract: 517,618. Phenol recovery. JOHNSON, G. W. (I.G. Farbenindustrie Akt.-Ges.). July 27,1938, No. 22361. [Class 2 (iii)] Phenols are removed from oils and waste aqueous liquors by first extracting the oil at elevated temperature and pressure with a waste aqueous liquor containing phenols, separating the extract by cooling into water and water containing phenols and finally treating the latter with known, extraction or adsorption agents for phenols, e.g., tricresyl phosphate, benzene or active carbon. Thus, oils obtained from the distillation of coal' or tar, coking, low temperature carbonization, destructive hydrogenation or solvent extraction are mixed in the ratio of 1:¢ to 1:5 with the waste aqueous liquors to be freed from phenols and heated to 200-280‹ C. at 30-80 atmospheres ; the aqueous extract is first separated at the prevailing pressure and then cooled to give two layers of which one consists mainly of phenols and the other of water containing 10-15 grams of phenols per litre, from which the .phenols are extracted in known manner with organic solvents or adsorbents. The layer formation is assisted by the addition of readily boiling hydrocarbons before or after the cooling. A part of the water separating from the extract may be freed from phenols as described, and the remainder returned in circulation to the extraction vessel. Examples are given.

Abstract: 720,345. Radar. LEVELL, D. A. Aug. 18, 1953 [Sept. 5,1952], No. 22396/52. Class 40 (7). To prevent the side lobes of the pattern of a directional radar receiving aerial causing spurious indications, two receiving systems are used, each capable of handling signals over a wide range of amplitude. The sensitivity of the first receiving system is made directional and exceeds, in its region of maximum sensitivity, the sensitivity of the second system while for other directions the sensitivity of the second system is the greater. The output from the second system is subtracted from that of the first to yield an output only from objects in the region of maximum sensitivity of the first system. In one embodiment the radar system is provided with a rotating transmitting aerial 1 to which is mechanically coupled a directional receiving aerial 2 and a substantially omnidirectional receiving aerial 3. The aerial 3 is shown as rotating but need not do so, it should have substantially the same characteristic in the plane at right angles to the plane of rotation as the aerial 2. Signals received by aerial 2 are mixed with oscillations from a common local oscillator 4 to give signals amplified in I.F. amplifier 6 and video amplifier 7 before being applied to mixer 11. The signals from aerial 3 are mixed with oscillations from unit 4 at 8 and the signals produced amplified in I.F. amplifier 9 and video amplifier 10 before being applied in negative sense to mixer 11. The output from 11 is fed to a suitable display unit. Amplifiers 6 and 9 are preferably logarithmic amplifiers.
