In a preferred embodiment, the cross-reinforcing laminations extend lengthwise of the member a limited distance only adjacent the anchorage portion thereof. The reinforcing laminations may comprise glass or carbon fibres or metal wire and the matrix may be of an epoxy resin, a ceramic material or metal. The strands or fibres of the cross-reinforcing laminations may be formed of an homogeneous material, e.g. metal, the preferred cross-reinforcing members comprising strands or fibres of identical composition with the lengthwise reinforcing laminations. The anchorage portions preferably each comprise a plurality of longitudinally spaced parallel grooves or ridges extending transverse to the length of the member. The tension member may be used in combination with an anchorage having formations to engage in and mechanically key with the anchorage formations on the member, the anchorage optionally including a metal plate or part shaped to co-operate with the anchorage formations, a resin binder being optionally hardened in situ in the gap between the anchorage unit and the anchorage formations. In the embodiment described, the tension member 10 comprises a number of closely spaced laminations each comprising a large number of parallel glass fibre filaments, spun yarns or rovings extending continuously parallel to the length of the member and impregnated and bonded with an epoxy resin. The member 10 is provided at each opposite end with a large number of interleaved cross-reinforcing laminations 12 extending over a limited length of the member, those adjacent the centre line of the member being preferably larger than those adjacent the surfaces. Each anchorage unit comprises a metal yoke or cap 15 with an internal socket having two opposed walls 16, a metal anchorage plate 17 having a corrugated toothed surface being interposed between the member and each wall and attached to the wall by pins 18.

Title: Telegraphic keying circuits
Inventor: SKOBRANEK N
IPC: H04L17/02
Filed: 1972-07-03
Abstract: 1363553 Telegraph keying circuits SIEMENS AG 3 July 1972 [2 Aug 1971] 31015/72 Heading H4P  Single current signalling in a subscriber teleprinter connection line AnL is effected by a keying contact bk which in one position (as shown) connects the battery TB to the line AnL, and in the other position simultaneously cuts off the battery and shorts the line AnL through a diode, D in parallel with the RC circuit R1, C1. The keying contact bk is operated by a receiving relay B responsive to double current signals from a trunk FL. The diode D permits current to flow to discharge the capacitance of the line AnL; and the capacitance rings with the inductance of a receiving magnet EM connected to the line and thereby accelerates dropout thereof by cancelling remanent magnetism. The diode D is blocked during ringing. A resistor R2 across C1 is larger than R1 and discharges C1 when the keying contact is switched back to the position shown by a suitable double current signal received at B. The diode D also serves to decouple the subscriber line AnL when it is disconnected, and is therefore exhibiting voltage and current fluctuations, from the transmitting relay AI, AII in order to prevent erroneous operation thereof. The transmitting relay AI, AII operates contact a in response to subscriber teleprinter key sk, to send double current signals to the trunk, FL. The current in the subscriber connection line AnL, when bk is as shown, is kept constant by an automatic control circuit K, which also serves to conduct holding current for transmitter relay AI when bk cuts off the subscriber line AnL. The latter function may be performed by an adjustable extension line resistor (R H , Figs 3, 4, not shown); and contact bk may be replaced by a pair of simultaneously operated contacts (bk1, bk2).

Abstract: 1,196,682. Semi-conductor devices. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 5 July, 1967 [8 July, 1966; 21 July, 1966 (3); 29 July, 1966], No. 31051/67. Heading H1K. A solid state oscillator element comprises a thin film 32 of polycrystalline semi-conductor material situated on a conducting substrate 31 and having an upper electrode 35. The semiconductor material is of the type having two energy minima in the conduction band at different wave-vector values, electrons in the higher energy minimum having a lower mobility than in the lower one so that Gunn-effect oscillations can occur. Suitable materials are GaAs or GaSb, and Si, Ge and InSb are also referred to. The film 32 may be uniformly polycrystalline, or may include preferentially oriented polycrystalline regions 33, and the inclusion of deep level impurities such as O 2  or Au is stated to decrease the threshold field for production of oscillations. A method of making such an element comprises depositing a thin film 32 of GaAs on a Ta substrate 31 by vacuum evaporation from separate sources of Ga and As, the Ga: As atomic ratio varying in the range 0À2 to 3À0. Mo or SnO 2  are alternative substrate materials, and gas or liquid phase reactions may also be used to produce the GaAs body. O 2  may be incorporated into the film 32 from a heated gallium oxide source, gallium chloride also being heated in the same silica tube. The upper electrode 35 is formed by evaporation of Au, A1 or Sn. For operation the element is mounted in a resonant cavity.

Title: Improvements in or relating to controlling the flow of liquids in dish washing machines
IPC: A47L15/06
Filed: 1956-10-15
Abstract: 814,417. Dish washing machines. SHEPHERD, T. C. R. Oct. 7, 1957 [Oct. 15, 1956], No. 31331/56. Class 138(1). A dish washing machine comprises a receptacle in which the dishes are washed with liquid agitated by an impeller, a waste outlet leading from the receptacle to a comminuting device for solid waste coupled to the impeller drive, and a centrifugally-actuated valve, controlling the flow of water from the receptacle to the comminuting device, which is arranged to be closed on rotation of the impeller. As shown, a quantity of hot water controlled by the valve 27 (Fig. 1) and solenoid 33, operated by timer 34 and switch 29, is fed to the receptacle 5 through pipe 28, and the impeller 15 (Fig. 2) is rotated by the motor 8 and shaft 9 which also causes the weights 21 pivoted at 22 to fly outwards thereby lifting the conical valve member 19 into contact with seat 20 to close the outlet and allow the receptacle to fill with hot water. Solid waste removed from the dishes, settles to the bottom of the receptacle 5, accumulates in the chamber 7 and when the motor 8 is switched off by timer 34 the water drains through chamber 13 and outlet 14 whilst the solid waste is retained on the breakers 10, keyed to shaft 9, and jaws 11 of the comminuting device, so that when the machine is restarted for the second, longer wash, the solid particles are reduced to a small size. Hot water is fed to the receptacle and the motor is started when the second wash is initiated by the timing mechanism, but the water in-flow is allowed to continue and a quantity of water passes through the overflow pipe 23, 24 to the inlet 25 and flushes through the comminuting device thereby removing the treated waste. The motor 8 is stopped, the receptacle is drained and the cycle is repeated to rinse the dishes. In a modification, cold water is supplied to the comminuting device through pipe 39 and valve 37 instead of through overflow pipe 24. The Provisional Specification describes a similar apparatus in which the valve member is a centrifugally operated ball valve and in which the'liquid agitator and valve mechanism may be removed as a single unit from the rest of the apparatus into which it is sealed by a push-fit and states that the invention is also applicable to clothes washing machines and to a liquid agitating machine for industrial or laboratory purposes.
