Title: Improvements in and relating to hair pieces
Inventor: PORTMANS MARCEL LEON DIEUDONNE
IPC: A41G3/00
Filed: 1966-10-07
Abstract: 1,089,789. Hair pieces. PALBAR CO. Ltd. Oct. 7, 1966, No. 45001/66. Heading A4V. Means for attaching and holding a hair piece on the head of the user comprise a band having a portion of non-extensible or substantially non-extensible fabric or other material and gripping means for engagement in the hair of the user attached to flexible portions so as to be extensible to permit lengthwise displacement of the gripping means between an extended position and a gripping position in which the band extends over the head of the user with the gripping means embedded in the natural hair. Suitably the gripping means 2 consist of a plurality of prongs which may be made from a continuous length of wire or from synthetic plastics material and which are arranged side by side, each extending lengthwise in the direction of the band and having at their outer ends loops 4, whereby they may be secured to the band by stitching 5. Optionally the band 1, which conveniently is made from elastic or other flexible material, extends through a sleeve 6, being secured at an intermediate point by stitching 7, the sleeve having its inner side 9 made from a material having a roughened surface or nap of the kind which permits a similar material to be held face to face therewith simply by pressing and which therefore increases the grip of the band in the hair of the user. Conventional hairpieces made by attaching natural or synthetic hair to wire formers are attached to the outer surface of the band or to the corresponding surface of the sleeve, if present, by stitching.

Title: Turbine engine starting fuel control system
IPC: F02C7/26
Filed: 1976-11-10
Abstract: 1507798 Gas turbine engines - starting GENERAL MOTORS CORP 10 Nov 1976 [1 Dec 1975] 46752/76 Heading F1G [Also in Divisions F4 and G3] A starting control system for a gas turbine engine has a spray pilot fuel burner which is initially ignited by an ignition plug after a starter motor has rotated the turbine and a main burner manifold which is supplied with fuel after the turbine speed reaches a pre-set level. The starter motor and pilot fuel supply are stopped once the compressor output pressure reaches a pre-set level. A thermal switch ensures that fuel is supplied only from the main burner manifold when the burner wall temperature is high enough to vapourize the fuel for ignition immediately on starting. The circuit described is for starting an automobile gas turbine and includes an ignition switch (58) and a start button (62) which causes relays (66), (86) to close respective contacts to energize starter motor (70), ignition exciter (98) and after a 1 second delay to operate relay (220) to open valve (44) to supply fuel to the spray pilot nozzle (28). At 35% of operating speed switch (134) will close to energize relay (140) and open valve (50) to supply fuel to manifold burner (20) which is ignited by the pilot flame. When the compressor pressure reaches 6 p.s.i. at about half operating speed the pressure switch (78) opens to de-energize motor (70) and close valve (44). The igniter circuit remains operational for a further 30 seconds to ensure that the prechamber walls have reached a temperature at which the fuel will vapourize and thus prevent flameout. Under hot start conditions a thermal switch (146) will be closed to open contact (206) and thus inhibit the supply of fuel to the pilot burner and the fuel from the main burner will be ignited directly by the ignition plug (200) which is maintained in operation again for 30 seconds to prevent flameout.

Title: Improvements in or relating to Welding Thermocouples
Inventor: DOWNS ARTHUR
IPC: H01L35/08
Filed: 1965-11-04
Abstract: 1,162,137. Welding by fusion; making thermocouples. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 21 Oct., 1966 [4 Nov., 1965], No. 46871/65. Headings B3A and B3R. [Also in Divisions H2 and H5] In welding the casing 7 of a thermocouple 1 by the heating effect of electrons derived from a plasma arc generator 3; the sealing of the casing 7 stops current flowing through a circuit ineluding a wire 6 of the thermocouple and the arc plasma and this is detected and automatically causes the welding to be stopped. Six thermocouples are mounted in one end of a glass enclosure 2 connected through a buffer volume 10 to a vacuum pump 11. The plasma arc generator 3 using argon is located at the other end of the enclosure 2 and the plasma is directed towards a steel deflector 4 having a concave end 5. Flow of electrons to the workpieces is controlled by the voltage applied to them. The wires 6 are connected in turn through switch 36 to a battery 44 which provides a preheating current and charges a condenser 42 which provides the welding current. The casings 7 are welded by connecting them in turn by a switch 37 to a generator 46 producing a steadily increasing voltage. A checking circuit from a source 47 through a wire 6 and the plasma to the anode 12 of the plasma generator 3 is broken when the end of the casing closes due to fusion, whereupon a trip device 48 disconnects the generator 46 after a predetermined delay. The thermocouple cables are prepared for welding by drilling out the magnesium oxide insulation and the wires 6 to a depth of 1 mm., removing a further 0.5 mm. of the oxide insulation and bending the wires towards each other. The plasma arc generator consists of an insulating block 21, Fig. 2, mounting a conductive insert 25 carrying a tungsten cathode 14. An annular silver anode 12 is held by a threaded boss 13 against an alumina sleeve 20 surrounding the cathode 14. Cooling water inlet and outlet pipes 18, 19 are provided and argon is fed through a tube 27. A starting electrode is located downstream of the anode 12.

Filed: 1972-10-12
Abstract: 1385537 Digital transmission; error detecting STANDARD TELEPHONES & CABLES Ltd 12 Oct 1972 47027/72 Heading H4P A receiver compares locally-generated test patterns of bits with matching ones included by the transmitter in the message signal, in order to monitor any degradation in the transmission path. Six 6-bit test patterns (Fig. 2, not shown) are included in sequence (1, 2, 3) between blocks of message bits (X, Fig. 1, not shown). The receiver Fig. 3, extracts the data rate from the received signal and uses it to control both the "local standard" generator of test patterns, and also a gate G which feeds message bits to a retimer and reshaper 8 and the received test bits to a comparator 9. The phase of the locally generated patterns is automatically adjusted by the comparator, to hold them in phase with the received patterns. An excessive phase difference at the comparator output however operates an alarm (not shown). The error signal at 11 represents differences in waveform characteristics of the test patterns, this being approximately proportional to channel distortion. The output 11 has a high time constant to render it sensitive only to long term changes in received signal quality. It is said that the retainer 8 may be connected to the output 11 of the comparator 9 which then receives test and message bits but is inhibited during the message bits.
