Abstract: 1,114,461. Tape cable connectors. AMP Inc. 11 Oct., 1966 [23 Oct., 1965], No. 44984/65. Heading H2E. In a tape cable connector, the rear of each contact comprises a pair of hinged arms formed with lances which pierce the cable when the arms are closed around it, the contacts being looked by tongues in an insulating body. In one embodiment, Fig. 7, the hinged arms 8 are parallel to forward plug portions 10 of the contacts and slots in the edge of the cable 13 receive the hinges. In another embodiment, Figs. 1, 13, the hinged arms 4 of the contacts, when closed, are perpendicular to their plug portions 2, the lower arms 4 being received in apertures in the cable so that, on closing, the arms 4 lie perpendicular to the cable conductors. Resilient lances 22 on the body snap through apertures in a panel 26 to clamp the cable between the panel and connector housing. Instead of passing through apertures in the cable, the arms 4 may be closed around its edge (Fig. 10, not shown), to lie along and parallel to the cable conductors.

Abstract: 1427057 Polyester resins GENERAL ELECTRIC CO 4 Oct 1973 [29 Nov 1972] 46288/73 Heading C3R A high molecular weight linear or substantially linear polyester resin is prepared by subjecting a bis ester of a glycol and terephthalic acid to self-condensation in the presence of a minor amount of a fatty acid of the formula C n H 2n+1 COOH where n = 8-30. The preferred amount of fatty acid used is from 0À20 to 2À5% wt. based on the bis ester. Suitable fatty acids include caprylic, capric, lauric, palmitic and stearic acid. Suitable glycols are ethylene glycol, 1,3-propanediol, 1,4-butanediol, 1,4-dimethylol cyclohexane, 2,2-bis[4-(#- hydroxyethyl)phenyl]propane or a mixture thereof. The bis ester may comprise up to 15 mol. per cent of groups derived from other polyols, such as glycerol, and/or up to 15 mol. per cent of groups derived from other dicarboxylic acids, such as, isophthalic acid, succinic acid and napththalene dicarboxylic acid. The intrinsic viscosity of the product ranges from 0À6-2À0 dl./g. measured for example on a solution in a 60 : 40 mixture of phenol and tetrachloroethane at 30 C. The self-condensation may be carried out in 3 stages by (i) heating the bis ester under reduced pressure at a temperature of 250-300 C. preferably until the partially condensed polyester produced has an intrinsic viscosity of 0À3-1À0 dl./g., (ii) adding the fatty acid to the partially condensed polyester, (iii) continuing heating under reduced pressure. In the examples polyesters are produced by the 3-stage process using (a) a bis ester prepared by heating dimethylterephthalate and 1,4-butanediol in the presence of tetra-2-ethylhexyl o-titanate and (b) stearic acid as the fatty acid. Uses.-Moulding powders either alone or mixed with other polymers and fillers, e.g. glass filaments, wood flour, cloth fibres and clays and other conventional additives.

Abstract: 1394100 Mass spectrometers PERKINELMER CORP 17 Oct 1972 [18 Oct 1971] 47838/72 Heading H1D A multichannel mass spectrometer for determining the proportional quantities of the components of a gas mixture, has a plurality of collectors 22a, 22b, and 22c for collecting ions of the respective components, each with an associated output circuit for generating an output voltage proportional to the ion current, and means for maintaining the sensitivity of the spectrometer constant, regardless of collector ageing, temperature variation &c., in which a voltage proportional to the difference between a reference voltage and the sum of the output voltages from the collectors is employed to vary, by the same amount, gain control means in each collector circuit. As shown, the outputs are summed and compared with the reference voltage in the summing amplifier 30, the output from which is employed to vary the pulse length of square wave oscillations produced by circuitry 33, the pulses of which short out amplifiers in each gain circuit for the duration of the pulses, integrating circuits associated with the amplifiers providing the collector outputs. The reference voltage applied to the summing amplifier 30 may either be constant, or, as shown, proportional to the total pressure of the gas mixture, a variable resistor (R 9 , Fig. 2, not shown) in each output circuit permitting initial adjustment of the apparatus to provide readings from the various collectors proportional to the partial pressures of the constituents of the particular gas mixture under examination. Further circuitry is provided to energize an alarm-e.g. the lamp 40-if the output from the summing amplifier 30 exceeds a predetermined value. As described, the gas under examination is ionized by an electron beam projected through the chamber 10, and the resulting ions are accelerated into a magnetic analyser 20.

The invention relates to a gas turbine engine, the turbine comprising a stator blade assembly by which gases are directed on to the rotor blades, the gases discharging from the rotor blades when the rotor is stationary having a component of velocity in the circumferential direction. A set of blades is provided downstream of the rotor blades for causing the gases discharging from the rotor blades with a circumferential component when the rotor is stationary, to flow in a substantially axial direction, there being means responsive to the speed of rotation of the rotor for rendering the straightener blades ineffective at a certain rotor speed. The invention is applied to a gas turbine engine of the kind having a separate power turbine which is utilized for driving a vehicle, the power turbine being held stationary when the vehicle is stationary but the compressor and turbine ass - embly continuing to rotate so that gases pass to the power turbine even when it is stationary. The inlet guide blades of the separate power turbine are shown as 23, Fig. 2, the turbine rotor blades at 24, the rotor being shown in the stationary position, and the blades for causing the gas flow discharging from the stationary rotor blades with a circumferential component of velocity to issue in an axial direction being shown at 25.

Excess powder may be removed by a vacuum scavenging system. Each mould 1 may be in two parts, hinged as shown. A plurality of moulds may be arranged on the arms 6, Fig. 1 (not shown), of a table 5 and the spraying nozzles 2 may depend from arms 11 mounted on a hub 12 which is rotatable and vertically reciprocable. The flow of the material from nozzles 2 is preferably laminar and the perforations 3 may be grouped to assist the deposition of powder, particularly in the case of angular articles. Nozzles 2 may be axially rotated during the spraying action, and to determine the amount of material entering each mould, each arm 6 may be supported on a balance which can actuate switches to control the supply means.
