Abstract: 654,192. Moulding asbestos cement pipes. MAGNANI, A. July 20, 1948, No. 19466. Convention date, July 23, 1947. [Class 87 (ii)] Socket pipes of cement and asbestos or other fibrous substance are made from two tubular sections 1, 2 adapted to form the body and the socket respectively, the sections, whilst still in a wet condition, being partly fitted into each other and then pressed together in the region of overlap to unite them, suction being applied from the inside and pressure from the outside. The pipe 1 is mounted on a rotatable mandrel 4 and the socket on a rotatable porous sleeve 3 through which suction is applied. Pressure is applied by means of profiled shaping rollers 6, 6<SP>1</SP> which are moved axially towards the joint. The other end of the pipe is supported by rollers. In a modification the two rollers 6, 61 are replaced by a single roller of appropriate profile which is displaced radially with respect to the pipe against the portions to be joined.

Title: Improved protective control system for gas turbine plant

IPC: F02C9/16
Filed: 1962-05-21
Abstract: 1,037,324. Gas turbine engine fuel systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 13, 1963 [May 21, 1962], No. 19516/ 62. Heading F1G. In a protective control system for gas turbine engines utilizing an air/fuel ratio trip valve, the air flow signal for operating the valve in opposition to the fuel flow signal is derived from the difference in pressure between the total head in the ducting through which air passes to the compressor and the static head in the inlet annulus to the compressor blading. In the engine shown air is supplied through the ducting 2 to the inlet annulus 3 of the compressor 1 and the static pressures in the ducting 2 and inlet annulus 3 are measured by tappings 7b, 8b, the pressures being communicated through lines 7a, 8a to the compartments 7, 8 at either side of the diaphragm 6. Fuel is supplied to the engine through an air/fuel ratio trip valve 5, fuel being supplied thereto through inlet 5a and discharging therefrom through outlet 5b. The valve member is connected to the diaphragm 6 by means of a rod 6a. The valve 5 is thus subject to a signal of fuel flow derived from the fuel pressure drop and to a signal of air flow in the engine. The velocity of the air flow in the ducting 2 is assumed to be negligible so that the static pressure signal measured by the tapping 7b is substantially a measure of the total head in the ducting.

Filed: 1920-07-09
Abstract: 147,937. Signal Ges. Feb. 29, 1916, [Convention date]. Subaqueous audible signals.-The diaphragm p of a subaqueous sound transmitter or receiver is connected to the exciting or detecting device through an intermediate vibratory structure, such as the system n, f , m, which is closely coupled to the diaphragm and may have much smaller damping. The amplitude of vibration at the exciter or detector is thus made large compared with that at the diaphragm. The diaphragm and the intermediate structure may have the same or different individual frequencies, and the system as a whole vibrates with frequencies which lie above and below the individual frequencies, and with dampings which lie between the individual dampings. A second intermediate structure may be introduced, and the system as a whole may have several frequencies of vibration, at any of which the exciter or detector may be worked. The diaphragm may be so shaped, or formed with ribs, or centrally loaded, as to vibrate with maximum amplitude over an annular zone.

Abstract: 1353351 Isolating cross-linkable resins from their solutions BAYER AG 19 April 1971 [7 Feb 1970] 20380/71 Heading C3P [Also in Division B1] A process for the production of a substantially solvent-free, spontaneously cross-linking, highly reactive resin from a solution of the resin comprises continuously concentrating the solution through evaporation, optionally under reduced pressure, for 2 to 6 minutes residence time in a self-cleaning screw evaporator, the resin being heated both by external heating and through internal friction to a temperature not exceeding 120C. The resin, which has a softening point of from 75 to 110 C. and which begins to cross-link at a temperature of around 120 C., is the reaction product of a copolymer of (a) an olefinically unsaturated monomer containing a hydroxyl group, (b) an alkyl or cycloalkyl ester of an α,#-olefinically unsaturated carboxylic acid having 3 to 5 carbon atoms and optionally (c) one or more other comonomers, and an alkoxymethyl isocyanate having 1 to 18 carbon atoms in the alkoxy group or allyloxy methyl isocyanate. The resins are used as reactive powder lacquer binders. Monomer (a) may be mono- or di- (hydroxy methyl) norbornene, phenyl allyl alcohol, a hydroxy alkyl ester of acrylic, methacrylic, fumaric or maleic acid, trimethylol propane mono allyl ether or glycol monovinyl ether. Monomer (b) is suitably an acrylate or methacrylate ester.
