Title: Improvements in and relating to the attachment of a metal or other workable tag to a tape or the like
IPC: B68G7/12
Filed: 1946-10-25
Abstract: 618,137. Binding edges of non-metallic sheet material. PAPER FASTENERS, EYELETS & METAL SMALLWARES, Ltd., and WLASSAK, A. Oct. 25, 1946, No. 31664. [Class 42(i)] Metal, plastic or fibre tags are attached to tapes by securing an end of the tape in an overlapped end of the otherwise flat plate, wrapping the tape around the tag, mechanically folding the other end of the enclosed plate over the tape, and pressing one folded end into close physical contact with the wrapped middle portion of the plate. A machine for performing the folding and pressing operation comprises a base 9 with an overhanging arm 8. A die 13 having a slot therein for reception of the tag, and carrying a pressing slide 15, is mounted on the base, while a verticallymoving plunger 12, to which is fixed a head 24, is carried by the arm 8. A blade 14, in a slot in the head 24, is normally held in position by a bolt 28 pivoted on the arm 30 of a bell-crank lever, while a peg 37 on the head 24 is provided with a slanting face for engagement with a ramp formed on one side of an aperture in the slide 15. The end of a tape 2 is inserted in the bent-over end 4 of a tag 1, the tape then being rolled about the tag, which is placed above the slot in the die, and the plunger depressed. The blade 14 then folds the other end of the tag, at the same time compressing the springs 18a. The bolt 28 is then withdrawn as a result of the stops 23 turning the bellcrank lever 30, 34, and the springs 18a force the released blade 14 upwards. Further downward movement of the plunger causes the slide 15 to be operated by the ramp on the peg 37 to compress the fold. Release of the plunger 12 allows the slide 15 to be retracted by the spring 19, and the blade 14 to be returned by the spring 47 until re-engaged by the bolt 28. For additional security, the tag may be further bent between dies 43, 44, as shown in Fig 6.

Title: Improvements relating to cinematograph and other projection apparatus
IPC: G03B15/08
Filed: 1929-10-18
Abstract: 341,533. Kinematograph projection apparatus. LAWSON, Sir D., 15, Lower Regent Street, and WILSON, J. C., 22, Laurence Pountney Lane, both in London. Oct. 18, 1929, Nos. 31682/29 and 13770/30. [Class 97 (i).] In apparatus comprising one or more curtains in front of a projection screen and one or more shutters for cutting off the projection beam, the movement of the shutters is automatically effected by moving the curtains ; the shutters may also be rapidly opened and closed, independently of the curtains, when desired, and the shutters of two projectors may be connected so as to facilitate changeover. As shown in Fig. 6, pairs of shutters 3, 4 for two projectors are connected by rods 15, 19 and bell cranks 181 to arms 171 on a rock shaft 16 so that one pair opens as the other closes. The members of each pair of shutters may be mounted on links forming a parallel motion system so that downward and upward movements of the rods 15 cause the shutters to move to and from one another, or may be suspended, as shown in Fig. 2, by links 10, and by bell cranks 11 engaging a common pin 12 on a plate 13 connected by a spring-pressed bolt 14 to the rod 15. The bolts 14 may be released from the rods 15 when it is desired to open the shutters temporarily for inspection of the film &c. Changeover of the projectors is effected by manually closing a two-way switch 23 to cause one or other of two electromagnets 22 to attract its armature and quickly rock the shaft 16 through an arm 21. The curtains 1 covering the screen are opened and closed by means of a motor 2. The shutters are slowly opened and closed simultaneously with the movement of the curtains by a motor 5 operating through a belt 28, worm gearing 27<a>, crank 25, link 24, and arm 20 on the shaft 16. The arm of the crank 25 is in the form of a guideway for a block 26 carrying the crank pin 27, and means are described whereby, when the crank is in its normal position, as shown, the block may be rendered free to slide in the guideway and permit rocking of the shaft 16 for change-over of the projectors. By means of the electrical connections shown, and described in the Specification, the temporary closing of a switch 46 by hand causes the motors 2, 5 to start in unison to produce opening movements of the curtains and shutters, and the temporary closing of a switch 66 causes them to produce closing movements of the curtains and shutters which are completed together. According to the first Provisional Specification the electromagnets 22 may be axially disposed.

Patent GB-816506-A (GB)
Title: Improvements relating to the stiffening of textile fabrics
IPC: D06M15/693
Filed: 1955-11-07
Abstract: Poor-quality gauze or muslin-type loose woven fabrics are impregnated with aqueous dispersions substantially free from rubber containing a thermosetting synthetic resin intermediate at a water-insoluble stage and preferably a catalyst, and are heat-treated to harden the resin and provide an elastic, resilient material.  The fabrics are composed of cotton or regenerated cellulose or of both.  The resin may be an alkyd resin, obtained from a polyhydric alcohol and polybasic acid wherein one component is unsaturated, copolymerized with another monomer, e.g. styrene; an alkyd resin modified with linseed oil or an addition of styrene and linseed oil; or an etherified urea-formaldehyde or melamine-formaldehyde resin insoluble in water but soluble in an organic solvent such as butanol.  The resin dispersion, which may be applied by immersion, spraying or other methods and may be in the form of a foam, may also contain pigments, dyes, optical brightening agents, softening agents, waterproofing agents, mothproofing agents, flame inhibiting agents or bactericidal substances.  The fabrics may be treated with an aqueous solution of a watersoluble aminoplast, e.g. melamine-formaldehyde, or phenoplast before or after the treatment with the resin dispersion, the fabrics being dried between the successive treatments and both resins being insolubilized in a final heating stage.  Alternatively, the water-soluble phenoplast or aminoplast may be incorporated in the dispersion of the insoluble intermediate.  In another alternative, a small amount of resin dispersion may be insolubilized upon the fabric prior to the main application.  Open-mesh muslin fabric may be arranged in several superposed layers, possibly cross-wise, and treated to give a composite structure.  In Example (1) a fabric is impregnated with an aqueous dispersion of a urea-formaldehyde intermediate etherified with butanol and containing casein in solution; in other examples the resin intermediate is obtained from (2) phthalic acid and glycerol and is modified with oleic acid; (3) melamine and formaldehyde and is etherified with butyl alcohol; (5) ethylene glycol-maleic acid polyester dissolved in monomeric styrene and butylacetate, the aqueous dispersion thereof also containing a water-soluble urea-formaldehyde intermediate.

Abstract: 654,817. Moulding processes; mould and core materials; patterns. VITKOVICKE ZELEZARNY, NARODNI PODNIK, and PETRZELA, L. Dec. 10, 1948, Nos. 32012 and 32013. Convention dates, Dec. 12, 1947, and Feb. 5, 1948. [Class 83 (i)] A method of preparing moulds or cores, patterns or other casting equipment from sand, carborundum, glass powder or other powdered, granular, pasty or fluent material is characterized in that the basic material is mixed with an auxiliary material, e.g. a binder, which is hardened, after the basic material has the required shape imparted thereto, by the action of a further substance. The further substance, which may constitute or contain the hardening agent, may be in the form of a gas, vapour, or liquid, which is blown into the mould or core, or is used to wet the latter. In a modification, a substance containing silicon or silica in suitable chemical combination is added to sand and after the sand mass has been shaped it is penetrated by a gas, vapour, or liquid which causes silica to separate out from the added substance in the form of a gel, so that solidification of the shaped body takes place. The added substance or binder may be sodium silicate, ethyl silicate, or methyl silicate. The precipitant may be carbon dioxide, ammonia, hydrochloric acid, methyl alcohol, ethyl alcohol, or acetone. In another modification a material containing the hardening agent in a chemically-combined innocuous form is incorporated in the mixture of basic and auxiliary material, prior to or during the shaping thereof, in a solid form and is thereafter broken up into components by heat or other means, one at least of the components constituting the hardening agent. In a further modification the basic material is mixed with a material which causes separation of a gel from a material containing silica which is introduced into the shaped body in the form of a gas or vapour.

Class 80 (ii). Shafts 1, 2, e.g. between a marine turbine, an intermediate shaft and a reduction-gear, are universally coupled by three spheroids 8 compressed between a set of three radially-inward claws 6 in a surrounding housing 12 on one shaft 1, and three pairs of mid-loaded axial beams 9 supported circumferentially at their ends on two sets of three radially-outward claws 7 on the other shaft 2 arranged on each axial side of the claws 6, so that drive in both directions is always transmitted through all three spheroids 8. Parallel faced hardened inserts 10 on the claws 6 and beams 9 eliminate the radial component of the torque acting on the spheroids 8 which latter are retained radially by the housing 12 which also has hardened inserts 11. Axial movement of the spheroids and shafts is restricted by pegs 13, 14, and radial movement of the beams 9 is prevented by hooks 9a. The beams 9 are such as not to bend unduly under the torque-load and, to equalise the stress on each set of claws 7, the spheroid-plane is nearer to the inner set or, alternatively, Figs. 5 and 6 (not shown), the claws 7 may be circumferentially wider than those 6, and the beams 9 may be correspondingly thicker at their mid-region.

Filed: 1936-11-26
Abstract: 475,699. Fluid - actuated valves. BRONZAVIA SOC. ANON. Nov. 26, 1936, No. 32394. Convention date, Dec. 10, 1935. [Class 135] In a vacuum or compressed-air system for actuating one or more instruments, apparatus, or machines on an aircraft by virtue of the pressure difference between the system and the surrounding atmosphere, regulating means are provided to vary this pressure difference in accordance with the pressure of the surrounding air to ensure correct operation of the apparatus at high altitudes. In Fig. 1, various apparatus 2 are actuated by suction from a chamber 3 which is maintained at a desired vacuum by a pump or the like 4 working at a predetermined normal rate, the degree of vacuum being regulated by an air-admission device A which is shown more fully in Fig. 2 as a balanced valve 6 controlled by a barometric capsule 7. Thus, at high altitudes the capsule 7 expands and tends to close the valve 6 to provide an increased degree of vacuum in the chamber 3 for operation of the various apparatus. In the arrangement shown in Fig. 5, the vacuum in the chamber 3 is regulated independently of the rate of operation of the pump 4 by means of a diaphragm 11 carrying a valve seating 9 and moving against a spring 10 to regulate an air-admission opening between the seating 9 and a valve member 8, the position of which is regulated by a barometric capsule 12. This arrangement thus provides a constant pressure or vacuum regulation of the chamber 3 which is modified in accordance with the surrounding air pressure to give an increased pressure or degree of vacuum at higher altitudes.
