Title: Improvements in or relating to cells for spectroscopy
Inventor: HUGHES ALBERT COLIN
IPC: G01N21/03
Filed: 1952-10-28
Abstract: 722,967. Spectrometers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 28, 1953 [Oct. 28, 1952], No. 27016/52. Class 97 (1). A cell for use in spectroscopy of the kind in which one wall is movable to adjust the gap between the walls has a wedge member or members arranged for movement in a direction transverse to the direction of movement of the movable wall to effect such movement. As shown, the movable cell wall 17, for example of rock salt, is supported by screws 9 carried by a plate 20 attached to a member 14 sliding within a body 1 to which the fixed wall 6 of the cell is attached. The lower surface 27 of the member 14 is conical and rests upon the inclined ends of f bridge members 24 supported by a base plate 32 and urged outwardly by springs 25 so that their ends are pressed against the conical inner surface 29 of a barrel member 28 engaging a screw thread 2 on the outer face of the body 1. Rotation of the barrel 28 causes it to traverse the screw thread 2, whereby the conical surface 29 causes sliding movement of the wedges which themselves slide the member 14 within the body 1 to vary the gap between the plates 6, 17. The barrel 28 may be calibrated at 35 to indicate the width of the gap. A metal bellows 22 completes the cell, access to which, for the introduction of liquids, is attained through apertures normally closed by screws 13.

Title: Improvements in or relating to the formation of staple products from continuous filaments and to the use of such products
IPC: D01G1/10
Filed: 1935-09-30
Abstract: 463,485. Stapling continuous filaments. BRITISH CELANESE, Ltd., and DREYFUS, H. Sept. 30, 1935, No. 27017. Addition to 424,830. [Class 120 (iii)] Continuous filaments, e.g. of cellulose acetate, viscose, natural silk or a mixture thereof are converted into a staple fibre product capable of being subjected to a drafting operation for transformation into yarn by causing a bundle of continuous filaments of a total denier of 3,000 to 50,000 denier or more to pass in contact with a cutting surface movable in the same general direction as the bundle but at a different speed therefrom pressing the bundle against the cutting surface substantially at a point in the length of the bundle and collecting with little or no twist the continuous fibrous product thus formed. Alternatively, each of a number of bundles of continuous filaments having a total denier of the order desired may be so treated the continuous fibrous products thus formed being assembled and collected as a single product with little or no twist. The stapling operation resembles that described in Specifications 424,683, 424,752, 424,830, and 424,879 but differs therefrom in respect of the total denier of the material treated and in respect of the resulting product which is capable of being drafted. If the material treated contains a higher degree of twist than that desired the staple fibre product may be collected by a device inserting a reverse twist. Large slivers, i.e. from 20,000 to 50,000 denier may be collected in cans while rovings, i.e. 3,000 to 10,000 denier may be wound on flanged or flangeless bobbins, or on tubes by a flyer twisting device. In drafting the slivers or rovings produced as described above some of the longer staple fibres produced by the cutting action may be broken to a shorter length. The drafting may be performed in two stages, the first breaking the longer fibres and the second reducing the length of the fibres as a whole. The staple fibre product may be mixed with cotton or wool or a contrasting thread doubled therewith. The continuous filaments may be crimped or the material crimped after conversion into staple fibres, e.g. as described in Specifications 424,880, 442,073, and 459,781.

Title: Process and apparatus for the production of pile fabrics
Inventor: EWING HENRY
IPC: D04H11/00
Filed: 1950-11-07
Abstract: 697,738. Pile fabrics. BRITISH CELANESE, Ltd. Nov. 5, 1951. [Nov. 7, 1950] No. 27200/50. Class 140. In making pile fabrics by adhering loose fibres to an adhesive-coated.travelling web and hardening the adhesive, the fabric 1, withdrawn over guide roll 3 from supply roll 2, after application of a layer, 0.015in. thick, of adhesive from applicator 5 followed by flexible doctor 6, which adhesive is rendered tacky by heating elements 7, is run through two high voltage fields in succession. In the first field, established between condenser plate 12 and earthed wire grid 10, loose fibres 9 are applied to the coated fabric from perforated rotating drum 8, through grid 10, and become orientated by the field, while the path of the fabric therethrough is at an angle greater than 45 degrees to the vertical, preferably horizontal as shown. In the second field, established between earthed condenser plate 15 and plates 18, 19, 20, through which the fabric travels downwardly at an angle greater than 45 degrees to the horizontal, preferably 70-85 degrees thereto as shown, a more even distribution of the fibres is obtained, by causing fibres, which were merely supported by adhering fibres, to adhere. After the second electric field, the pile fabric passes round roll 33 and excess fibres are collected in box 35 while beater 38 assists in this removal, and finally passes through a hardening or vulcanising chamber. Condenser plates 12, 18, 19, 20, may be fed from a magneto, through a fixed spark gap and variable spark gaps 25, 26, 27, 28, to give an alternating voltage, e.g. 10,000- 100,000 at 8-15 cycles, of the character applied to the condenser in Specification 650,988, and condenser plates 12 and 15 may carry a layer of insulating material e.g. polyvinyl chloride or polystyrene. The field in the first condenser may also be constant in direction and intensity. The backing fabric or film may be the same materials as referred to in Specifications 697,739 and the fibres may also be any of these materials. The adhesive may be plasticised polyvinyl acetate as disclosed in Specification 644,002, plasticised butadiene-acrylonitrile copolymer, (see Specification 697,739) a gellable polyvinyl chloride or polyvinyl acetate paste, a heat hardenable polymer of diallyl or allyl phthalate, rubber latex, or aqueous polyvinyl acetate dispersions.

Title: Desacetylthiolutin, amides and salts thereof
IPC: C07D495/04
Filed: 1953-10-05
Abstract: An antibiotic, desacetylthiolutin, is produced by reacting thiolutin with an inorganic acid having an ionization constant of at least 10-2 in a two-phase organic solvent-aqueous system, preferably at 50 DEG to 100 DEG  C.  It is preferred to treat thiolutin in refluxing dioxane with concentrated hydrochloric acid.  The desacetylthiolutin, which separates, is dissolved in dilute hydrochloric acid, decolorized with activated carbon and crystallized.  Desacetyl thiolutin monochloride monohydrate displays ultraviolet absorption maxima at 226, 309 and 381 mm ; has a pKa value of 2.9 and formula C6H6ON2S2.  Desacetylthiolutin base is obtained from the hydrochloride by dissolving the hydrochloride in (a) water and adding a base such as ammonia, pyridine or sodium hydroxide; or (b) chloroform and treating with anhydrous ammonia. Thiolutin is reformed by treating an aqueous or organic solution of desacetylthiolutin with an acetylating agent such as acetyl chloride, acetic anhydride, ketene or acetylbromide.  A propionylating agent such as propionyl chloride, propionyl bromide or propionic anhydride converts desacetylthiolutin to aureothricin.  Desacetylthiolutin forms salts with acids such as hydrobromic, phosphoric, sulphuric, tartaric and citric. Specification 692,066 is referred to.

Title: Method and devices for the production of artificial sausage skins
IPC: B29C48/03
Filed: 1934-09-24
Abstract: <PICT:0433245/IV/1> In the extrusion of sausage casings from a plastic kneadable mash of animal or vegetable substances, the fibres of the mash are orientated in the annular die to give maximum strength to the casing, by means which impart a rotary movement to the material in the die.  As shown, the mash is fed, under pressure, to the annular die space 4 by a number of tangentially arranged tubes 11, 13 spaced circumferentially, and the rotation of the material is effected by the rotation of a portion 3 of the die which is driven by gears 26, 22, 21.  The rotation is in the same direction as the tangential feed of the material.  In the part of the die influenced by the rotary part 3, the fibres become orientated in transverse or circumferential directions.  The fibres at the surfaces of the casing are re-orientated in longitudinal or axial directions, to produce an interlocking of the fibres, by arranging a stationary bush 6<1> in front of the part 3 to form a stationary nozzle.  Circumferential grooves 31 in the bush 6<1> or in the bush 30, or in both, allow the material to accumulate therein to increase the friction, this effecting an additional re-orientation of the fibres.  Air is blown through the bore 10 to inflate the extruded casing.  The packings 32, 33 are adjustable by screws 34, 35.  The inner core 5 on which the part 3 rotates is integral with the frame 1<a>.

Abstract: 1,273,000. Heat-shrinkable plasticized polyvinyl chloride film. UNION CARBIDE CORP. 29 May, 1969 [29 May, 1968], No. 27355/69. Heading B5B. A biaxially oriented heat shrinkable plastcized polyvinyl chloride film containing 25 to 50 parts of plasticizer per 100 parts of polyvinyl chloride resin exhibits a shrinkage of 18 to 60% at 90 C. and a permanent deformation of up to 15% when tested at ambient conditions of from 15 to 33 C. upon being stretched up to 75% after such shrinkage. The polyvinyl chloride resin may have an inherent viscosity of 0.8 to 1.4 and may be a homopolymer or a copolymer with vinylidene chloride, vinyl acetate, or acrylonitrile. The plasticizer may contain 5 to 10% of epoxidized soybean oil in addition to conventional plasticizers. The film may exhibit minimum shrink forces on heat shrinking at 90 C. of 45 g./mil. in the longitudinal direction and 25 g./mil. in the transverse direction and may exhibit a minimum oxygen transmission rate of 180 cc./mil./24 hr./100 sq. in./atmos. In Example V films having water vapour transmission after shrinking of 24 and 11 gm./mil./ 24 hrs./100 sq. in./atmos. are described. The film is made by conventional processes of tubular melt extrusion followed by transverse and longitudinal stretching and may be used for packaging food, when the film is fabricated into packages by conventional heat sealing methods and heat-shrunk on to the food. The packages may be used for display and "cook-in" purposes as the film exhibits good elastic recovery at refrigeration temperatures and good stability at temperatures at least up to 107 C.

Title: Improvements in and relating to radio signalling systems
Inventor: SPENCER HERBERT CYRIL
IPC: H04B7/12
Filed: 1956-09-07
Abstract: 856,972. Radio signalling. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Aug. 30,1957 [Sept. 7,1956], No. 27518/56. Class 40(5). In a frequency diversity radio signalling system at two carrier frequencies each modulated by the same signals are transmitted alternately, and the receiver has a bandwidth capable of receiving the two carrier frequencies. Fig. 2 shows a multivibrator circuit combined with two crystal controlled Colpitts oscillator circuits which are utilized at the transmitter to provide the two carrier frequencies. The multivibrator which is arranged to have a switch-over frequency of 5 kc/s., is of conventional design and includes the triodes 30, 31, which also act as oscillators controlled by the crystals 49 and 54 respectively. The alternate bursts of oscillation from the output leads 55, 56, are fed via respective buffer amplifiers, Fig. 1 (not shown) to a common amplifier and frequency multiplier, the output of the multiplier consisting of carrier frequencies of 100 mc/s. and 106 mc/s. which are modulated from a common audio-frequency source and applied to the aerial. At the receiver the received signals are applied to a radio-frequency amplifier having a frequency response with two peaks at the carrier frequencies of 100 and 106 mc/s. respectively and centred on the mean frequency of 103 mc/s. The output of the amplifier is fed to a mixer which is supplied with oscillations at a frequency of 103 mc/s. from a local oscillator, thus providing an intermediate frequency of 3 mc/s. for each carrier frequency. After demodulation the resulting audio frequency signals are amplified and fed through a low-pass filter cutting off at 4 kc/s. and thus removing the 5 kc/s. switching frequency. Instead of the transmitter having two separate oscillators two crystals may be switched alternately in and out of a single oscillator, or a single oscillator may be frequency modulated under the control of a further source of oscillations of rectangular waveform.

Abstract: 692,811. Control of D.C. motors. ENGLISH ELECTRIC CO., Ltd. Nov. 9,1951 [Nov. 14, 1950], No. 27826/50. Class 38 (iii) Relates to an electric motor control system for setting a motor-driven member to an intermediate position or to either of two extreme positions. The motor 10, which may be coupled to a three-way air valve, has reversing field windings 10a, 10b, and is supplied through cam-operated limit switches 12, 13, and control switches 14, 15. The switches 12, 13, are respectively actuated by motor-driven cams 16, 18, and have operating plungers 12a, 13a, so arranged that the limit switches are tripped and re-set at different positions of the plungers. As shown, the field winding 10a is energised for clockwise rotation through contacts 12b which are opened when the valve reaches the zero-degrees-position, the contacts 12c then being closed to connect field winding 10b to one pole of an emergency switch 15. If the switch 14 is now changed over, the field winding 10b is energised for anti-clockwise rotation to drive the valve to the 180-degrees-position whereupon contacts 13b are opened and contacts 13c are closed. During this movement the cam 16 will re-set the switch 12 as it passes through the 90-degrees-position. With the valve in either of the extreme positions, movement of the emergency switch from the position shown will result in one or other of the motor field windings being energised through contacts 12c or 13c. The valve will then be moved to and stopped in the 90-degrees-position. Subsequent return of the switch 15 will result in the valve being driven to one of the extreme positions in accordance with the position of the switch 14. The switch 15 may be replaced by intermediate contacts on the switch 14. The plungers of the limit switches may be operated through levers, as shown, or directly from the cams. A single-cam arrangement is referred to.
