Title: A mechanical warp stop-motion having a braking arrangement for jute looms
IPC: D03D51/20
Filed: 1938-06-16
Abstract: 515,326. Warp stop-motions. FLEISCHMANN, H., and GELLER, J. June 16, 1938, No. 17950. Convention date, June 16, 1937. [Class 142 (i)] In jute looms wherein there is a considerable difference in height between the back rail and shuttle box, warp stop motion droppers arranged in step formation are used. Carrier heads b are used with stepped recesses c for accommodating the U-shaped guides W<1> in which the usual toothed rails W are reciprocated, the guides W<1> also guiding the droppers. The rails are reciprocated by lever mechanism e.g., and a cam on the shaft d, a stop k being also normally moved vertically by lever mechanism h, i so as not to be struck by a lay stop m. On warp breakage the vertical movement of the stop k ceases and it is struck by the stop m, the starting handle being thereby moved to the off position pulling with it the horizontal arm of the weft fork lever. An angle lever resting on this then falls and by means described a brake band attached to a weighted lever is caused to press against a brake disc to stop the loom.

Abstract: 375,992. Printing-machines. M A I - LANDER, W., 68, Hallstrasse, Cannstatt, Stuttgart, Germany. June 22, 1931, No. 18013. [Class 100 (i).] Sheet-registering devices.-Metal sheets d are fed to the grippers b of the impression cylinder of a rotary printing-machine from a feed table c by means of a constantly driven roller which is spring-pressed against the table c, and registration of the sheets is effected by means of a rising stop e which rises to release the sheet just before a curved registering- device f on t h e grippers b attains the position shown in Fig. 2. The speed of the sheet is controlled by the rate of outward swing of the stops e, and the sheet is accelerated until it attains the speed of the cylinder a. The registering- device f is so shaped that, as the grippers close on the sheet, the sheet is constantly in a position normal to the curved surface of the registering-device. The lower surface of the stop e is formed with a surface which is inclined downwardly in the direction of movement of the sheet and preferably takes the form of a rotatable roller k, thus permitting of the acceleration of the sheets as the stop rises without danger of the sheets clinging to the stop.

Title: Improvements in and relating to thermosetting aminoplastic moulding compositions
Inventor: BROOKES ALFRED
IPC: C08K5/42
Filed: 1948-07-06
Abstract: In a moulding composition for producing products with a translucency comparable with that of natural horn and comprising at least 50 per cent by weight of urea-formaldehyde resin, a filler which is wholly or mainly finely comminuted regenerated cellulose and an acidic or potentially acidic accelerator, there is included as mould lubricant a highly sulphonated castor oil soluble in the resin or resin solution and stable in the presence of the accelerator.  The regenerated cellulose may be fibre, yarn, foil or trade waste. Preferably, the sulphonated oil is soda or ammonia finished.  Up to 1 per cent of the lubricant may be used. Colouring materials soluble in the resin or pigments of high tinctorial value but low opacity may be included.  Plasticizers which do not render the products opaque are described in Specifications 567,705 and 581,702.  Small proportions of usual lubricants (e.g. zinc stearate or carnauba wax) may also be added, but the amount must not be sufficient to cause opacity. Preferably, aqueous solutions of the resin are employed in production of the moulding powder, but alcohols may also be added if desired. In the example, monopole oil ARH, a soda finished sulphonated castor oil, is added to a urea-formaldehyde syrup, and the mixture used to impregnate guillotine trimmings from reels of regenerated cellulose wrapping foil.  The mass was dried and ground, hexamine thiocyanate and hexamine base were added as curing agents and a little zinc stearate as supplementary mould lubricant.  Specifications 531,446, 590,955 and U.S.A. Specification 2,056,442 also are referred to.

Title: Separation of ferro-magnetic particles from non-magnetic particles
Inventor: JENSEN EJLER
IPC: B03C1/22
Filed: 1966-04-26
Abstract: 1,077,436. Magnetic separators; separating granular materials. F. L. SMIDTH & CO. A/S. April 26, 1966, No. 18241/66. Headings B2H and B2J. Ferro-magnetic particles are separated from non-magnetic particles in a mixture of finegrained materials by causing the mixture to flow as a gas-fluidised stream beneath an endless belt-type magnetic separator. In Fig. 1, the mixture of materials is fed via a chute 1 on to a gas-permeable bottom of a fluidised-bed conveyor which is closed at the top partly by a cover 7 and partly by an endless belt 8 within which is mounted a magnet 9. Fluidising air is introduced through a pipe 3 leading to distribution chambers 4, 5. Magnetic particles carried by the belt are released from magnetic attraction when the part of the belt comes over a chute 10 down which the magnetic particles fall. The non-magnetic particles are discharged through a chute 6. Transverse ribs 12 are provided on the belt to cause the magnetic particles to be carried by the belt beyond the edge 11 of the magnet 9. In another embodiment Fig. 2 (not shown) the chute (1') has a gas-permeable, steeply sloping bottom (2') and baffle plates (16, 17, 18) are provided to cause the material itself to form a gas seal at the entrance to the fluidised-bed conveyor. The bulk of the material passes over baffle (17) and heavy particles pass through the narrow clearance (21) which may be adjusted by adjusting the plate (17). The size of the entrance (19) for the material may be adjusted by adjusting the plate (16). The magnetic separator comprises a magnetic drum (9') over which a belt (8') passes. Magnetic particles are discharged through a chute (10') and non- magnetic particles through a chute (6'). Non- magnetic particles entrained with magnetic particles are removed from the belt by compressed air blown through a pipe (13). Dustladen gas is discharged via an outlet (14).

Filed: 1969-04-09
Abstract: 1,261,399. Magnetic compositions. STAMICARBON N.V. 9 April, 1969 [9 April, 1968 (2)], No. 18245/69. Heading H1H. [Also in Divisions C1 and C7] Supported permanently magnetizable metal (s) or alloy(s) are produced by suspending a finelydivided carrier material in a solution containing the metal ions and gradually generating OH<SP>1</SP> ions homogeneously in the solution at a sufficient rate to deposit the active element(s) on the carrier but not fast enough to get nucleation of the pure precipitate in the solution, the precipitate being hydroxide or hydrated oxide, removing the carrier from the solution and then reducing the precipitate to give metal or alloy particles of size in the single-domain range. The reduction may be by means of hydrogen, optionally in the presence of water vapour, or by hydrazine and the precipitate may be calcined in air before reduction. The loaded carrier materials may be impregnated under vacuum with a polymerizable monomer or molten polymer for application to tapes or for the production of sheets or moulded bodies to form magnetic recording material. The examples refer to the deposition of Fe or Ni- Co alloy on SiO 2  particles.

Title: Electrooptical modulations employing chromatic polarization
IPC: G02F1/03
Filed: 1973-04-16
Abstract: 1396828 Modulating light THOMSON-CSF 16 April 1973 [17 April 1972] 18306/73 Addition to 1364274 Heading H4F When an electric field is applied across the thickness of a perpendicularly aligned nematic liquid crystal film, to alter the direction of molecular alignment and the birefringence of the film, the uniform alignment may be lost and a plurality of differently aligned domains produced, each having the same degree of birefringence but different principal directions. Such a film would not be suitable for placing between crossed polarizers for modulating the intensity of monochromatic light or the colour of polychromatic light. In a first method of overcoming such difficulty, #/4 plates or the equivalent thereof are placed between each polarizer and the nematic film and may form the plates bounding the nematic film. In a second method a further continuous constraint is applied to the nematic material to ensure that the alignment remains uniform as the molecular orientation alters. The surfaces of the film may be in contact with surfaces which have been uniformly scratched by rubbing, to an extent insufficient however to influence the initial molecular orientation. Alternatively a magnetic or electric field is imposed parallel with the plane of the film.

Title: Process of treating dilute aqueous rubber dispersions
Inventor: BAGNALL WILLIAM HENRY
IPC: C08J3/03
Filed: 1953-07-02
Abstract: A dilute aqueous rubber dispersion, e.g. latex skim, is floculated by adding, e.g. sulphuric, hydrochloric, formic or acetic acid, the flocculated rubber filtered, washed, and drained, and a non-ionogenic surface active agent is added to the flocculated rubber to redisperse it.  The acid latex produced on redispersion, may be treated with concentrated sulphuric acid to cyclise it, reacted with hydrochloric acid to form rubber hydrochloride, treated with chlorine to form a chlorinated rubber, or treated with sulphur dioxide or acidic oxidants.  The amount of the agent used may be from .5 to 5 per cent by weight of the rubber solids.  The agent may be a condensation product of polyethylene glycol with a long chain carboxylic acid, alcohol, organic amine, organic amide or alkyl phenol.  The latex may be subsequently made alkaline by adding ammonia.  Specification 553,249 is referred to.
Patent GB-968057-A (GB)
Title: Process for the preparation of cation-exchange membranes
Inventor: COOKE BRIAN ALFRED
IPC: C08J5/20
Filed: 1962-05-14
Abstract: Cation-exchange membranes are prepared by treating sheeted thermoplastic polymers containing styrene in polymeric form with a cation-exchange group donor reagent and 0.01-5% of formaldehyde. The polymer may be, e.g. 10-35%, polymeric styrene and a carrier of polyethylene or polypropylene.  The membranes may be manufactured by causing the carrier polymer in comminuted form to imbibe a quantity of styrene until the styrene is fully absorbed, heating the mixture to polymerize the styrene, e.g. using benzoyl peroxide as catalyst, forming the polymer into a sheet and treating the sheet with a sulphonating agent, e.g. chlorosulphonic acid, sulphuryl chloride or ether complexes of sulphur trioxide or a complex of sulphur trioxide and 1:4 dioxane, and the formaldehyde.  The membrane may then be immersed in sodium hydroxide solution to hydrolyse e.g. the sulphonyl chloride groups and to convert the membrane to its sodium form.

Title: Improvements in or relating to the treatment of crude oils, tars, bituminous residues and the like
IPC: C10C3/02
Filed: 1928-03-23
Abstract: 319,718. Bolgar, L. March 23, 1928. Divided on 319,673. Pitch and tar.-Crude oils, tars, and bituminous residues are mixed with a reagent such as sulphuric acid, waste acids, or substances containing sulphuric acid such as acid sludges and the mixture is heated to over 180‹ C. Stearin pitch is added before or during the acid treatment and the mixture is further heated, after which filling materials are added and the composition is pressed to form an ebonite-like product. The filling materials comprise sand, stone meal, steatite meal, fibrous substances, asbestos or mixtures of these materials. To prevent foaming during the acid treatment, high temperatures between 250-260‹ C. for petroleum residues and 180-220‹ C. for coal tar residues may be employed. The quantity of sulphuric acid may amount to 25 per cent by volume for treating petroleum pitch and should not exceed 6 per cent for coal or brown coal pitch. For decreasing brittleness, escape of oils may be prevented by means of a backflow cooler or other oils may be added. The temperature may be raised to over 200' C. to decompose the acid and a fluxating agent added. The acid-treated substance may be treated with bases such as soda lye to raise the melting point. In an example 6 per cent by volume of sulphuric acid of 50‹ Beaume is added at 200' C. to a mixture of 1 kg. of coal pitch and 5 dkg. of stearin pitch. The product is heated to 250‹ C. and 3 kg. of stone meal and 15 dkg. of asbestos are then added, the composition being pressed hot..
