Title: Adhesion of rubbery polymers to fibrous materials
IPC: C08J5/06
Filed: 1956-12-04
Abstract: A fibrous material made from, for example, cotton, rayon, silk or nylon, is coated in the first place with a phenol-aldehyde resin, and in the second place with a chlorinated butyl rubber having a chlorine content of from 0.5 per cent by weight to not more than one atom of chlorine per molecule of multi-olefine in the butyl rubber.  The chlorinated butyl rubber may be compounded with up to 10 parts of mould release agent, e.g. stearic acid, up to 150 parts of fillers such as carbon black, clay and silica, up to 50 parts of a basic metal compound such as zinc, calcium and magnesium oxide, and up to 5 parts of anti-oxidant such as phenyl b -naphthylamine per 100 parts by weight of rubber, and may be dissolved in a solvent such as kerosene, naphtha, mineral spirits, gasoline, hexane, heptane, benzene, toluene, ethyl chloride, chloroform, carbon tetrachloride and carbon disulphide.  The chlorinated rubber may be prepared from butyl rubber containing 85-99.5 isobutylene with butadiene, isoprene, dimethyl butadiene and piperylene, by reacting a solution of the copolymer with chlorine, alkali-metal hypochlorites, sulphur chlorides, pyridinium chloride perchloride, N - chlorosuccinimide, phthalimide in gaseous form or as a solution in alkyl chloride and carbon tetrachloride.  The phenolic compounds used to produce the resins may be phenol, cresol, phloroglucinol, xylenols, trimethyl phenols, mono- or di-chlorophenols, diamyl or diisopropyl, p-t-butyl and p-phenyl phenols, hydroquinone or resorcinol with aldehydes such as acetaldehyde, propionaldehyde and furfural. The fibrous material in the form of tyre cords, or fabrics are embedded in natural or synthetic rubbers and vulcanized, to yield material suitable for tyres or conveyer belts.ALSO:Fibrous materials, e.g. cotton, rayon, silk and nylon cords, are coated in the first place with a phenol-aldehyde resin and then further coated with a chlorinated butyl rubber having a chlorine content ranging from 0.5 per cent to not more than one atom of chlorine per molecule of multiolefine present.

Title: Improvements relating to fire extinguishing apparatus
IPC: A62C35/60
Filed: 1928-12-17
Abstract: 302,591. Martin, J. Dec. 16, 1927, [Convention date]. Alarms operated by fusible devices.-A. device for operating from a distance, both automatically and by hand, extinguishers mounted, for example, on aircraft, comprises a tubular casing A in which is slidable a piston B formed with a groove C, a frusto-conical part C<1> with a flat K, a groove 1, a shoulder C<11>, and a cylindrical part Y, The piston is connected by a cable J to the extinguisher, is urged to the left by a spring E, and is held from movement by a ball D engaging the groove C. The ball D is movable in a slot in a cylinder G in which works a piston F formed with a groove 2. The piston F is urged to the left by a spring H held under compression by a cable I embodying' fusible devices arranged at dangerous points. The piston B is provided with a handle L and with a stop device M carrying a pointer N and engageabie in a slot, Fig. 3, in the casing A. The device is in the ready position with the parts arranged as in Fig. 1, the stop M being at the point 4, Fig. 3. In case of fire melting a fuse in the cable I, the piston F moves to the left until the ball D can rise into the groove 2. The piston B then moves to the left, so that the extinguisher is operated by the cable J. The piston F, in moving, pushes down a shutter P to expose a signal disc O. For hand operation, the handle L is turned until the flat K is beneath the ball D, when the piston B is again free to move under action of the spring E. The automatic piston F is unaffected by hand operation of the piston B. To reset the apparatus, the piston B is pushed right in and turned until the stop M is in position 3, Fig. 3. The piston F and fuses are then reset, and the piston B turned to position 4, Fig. 3. The pointer N works over a disc Z bearing indications of the position of the pointer B. A suitable fuse consists of a plunger S held in a cylinder R by fusible solder T, Fig. 4, or of two members U, U' held together by solder V, Fig. 6. The Specification as open to inspection under Sect. 91 (3) (a) states that the melting of the fuses may also set into operation a light or like signal. This subject-matter does not appear in the Specification as accepted.

Title: A Laminar Flow Fluid Control Device
IPC: F15C1/14
Filed: 1967-08-14
Abstract: 1,187,287. Fluid switch. TEXTRON Inc. 14 Aug., 1967 [27 Sept., 1966], No. 37244/67. Heading G4P. [Also in Division G3] A proportional amplifier, Figs. 1, 3A, 3B, 3C (also Figs. 2A, 2B, not shown) is characterized in that it uses lamina flow, this being achieved by a relatively long inlet channel 20 which progressively tapers, see Fig. 3C, in a vertical plane, from just beyond the interaction region 30 up to the output channel, and also in that the control signal is arranged to produce a static pressure which acts along a length of the power jet longer than its width. In operation, with no control signal the main jet flows direct to the main outlet (Fig. 3A). With an increasing control signal the main jet is progressively displaced towards a side vent 43, until, with a sufficiently large control signal, the main jet flows entirely into the vent (Fig. 3B). The control pressure/input pressure characteristic (Fig. 4, not shown) for the arrangement displays a significant linear portion. A modification with an off-centre outlet is described (Fig. 7, not shown). A switch having a characteristic (Fig. 6, not shown) with no significant linear portion, is produced by coupling the two vents 42, 43 of the proportional amplifier shown in Fig. 1. The main jet then flows either direct to the main outlet, Fig. 5A, or to the vented loop, Fig. 5B, and it is substantially impossible to divide the main jet between the main outlet and the vented loop because once flow commences in the loop it exerts positive feed-back and causes rapid switching.

Title: Machine for washing mussels
IPC: A22C29/04
Filed: 1928-12-20
Abstract: 303,155. Debackere, A. Dec. 29, 1927, [Convention date]. Fish, treating.-In a machine for washing mussels, the mussels, contained in a vessel, are displaced and simultaneously acted upon by jets of liquid. As shown in Fig. 1, the mussels are contained in a rotary drum consisting of side plates 2 and cross bars 1, the drum having a solid shaft 3 journaled in a bearing 5 and a hollow shaft 4 journaled in a bearing 6. The bearings are supported on a frame 10 carrying a bracket 9 which supports a watersupply tube 8 passing axially into the drum. The tube 8 has slots which deliver jets inclined to the vertical plane passing through the axis of the drum, in the direction of rotation of the drum. The mussels tend to accumulate to this side of the said vertical plane, and the jets thus impinge on the thickest part of the heap of mussels, which are agitated by the rotation of the drum. The water passes out through the bars and is guided by a metal plate into a receptacle in which the foreign matter accumulates whilst the water escapes. A section of the bars 1 is hinged to the drum to provide a charging and discharging door.

IPC: G01R31/02
Filed: 1958-11-25
Abstract: 848,750. Testing electrical insulation. OKONITE CO. Nov. 25, 1958, No. 37908/58. Class 37 Imperfections such as voids or air spaces in electric insulation, for example the insulation of an electric cable, are detected by passing the insulation through a tank containing a conducting fluid with a high voltage source connected between a continuous internal conductor of the insulation and the fluid. The insulation is also subjected to a radiation source as it moves through the fluid to ionize the gas in the voids a device being connected between earth and the high voltage source for indicating variations in the dielectric stress of the insulator. Fig. 1 shows an apparatus for continuously testing the insulation of an electric cable 10 which is drawn-off from a drum 8 on to a drum 12 and has its centre conductor earthed. The cable is passed through a tank of insulating material 2 filled with a conducting fluid 4, for example water, and a high voltage source from a transformer 18 is connected between earth and an electrode 32 immersed in the fluid so that as the cable progresses through the tank a progressive and continuous electric stress is applied across the insulation. A device 6 in the tank radiates any voids or gaps in the cablefrom a source of gamma, X-rays or beta rays thereby ionizing any gas in voids in the insulation. The source of radiation may be a conventional X-ray tube, Fig. 2 not shown, or a source of gamma rays if the insulation is shielded. If the insulation is unshielded a source of beta rays may be used. The gamma or beta rays may be produced from a source of radio active material suitably housed, Fig. 3 not shown. Any variation in the dielectric stress of the insulation due to the presence of air gaps or voids is detected by a radio receiver 34 which may be associated both with an aural recording means or a recording galvanometer 40 and from the record both the presence and location of a fault is recorded.
