Abstract: 1470959 Laminated safety glass TRIPLEX SAFETY GLASS CO Ltd 28 May 1974 [4 June 1973] 26480/73 Heading B5N Flat or curved laminated glass windscreens are made by maintaining glass sheets, assembled with a transparent thermoplastic interlayer therebetween, at an elevated temperature whilst applying pressure to the major faces of the sheets for full bonding and cooling the bonded assembly, the pressure at the periphery of the interlayer being maintaned at a controlled amount lower than the aforesaid pressure for at least part of the period at elevated temperature. The reduced pressure may be applied via a flexible peripheral hollow rubber ring communicating with a pressure source or a vacuum pump. The interlayer may be polyvinyl butyral, in which case the bonding and peripheral pressures are both above atmospheric; bonding may be carried out in an autoclave at 2À0-14À0 kg./cm.<SP>2</SP>. Alternatively, the interlayer may be an ethylene copolymer as described Specification 1,166,443, when bonding is carried out in an oven at atmospheric pressure and the peripheral pressure is sub-atmospheric. When an autoclave is used, several assemblies may be stacked vertically therein (a suitable support being illustrated) and connected to a pressure manifold for applying the reduced pressure to the peripheral hollow rings. Preferably the assemblies are subjected to a pre-bonding process in which the peripheral zone is subjected to a vacuum via the hollow rings, e.g. at room temperature and at 90-120‹ C.; full bonding is then carried out at 120-160‹ C. with the desired peripheral pressure in the rings. When an autoclave is used, pre-bonding may take place inside or outside the autoclave. When bonding takes place at atmospheric pressure, the peripheral vacuum is maintained after prebonding. The pressure differential may be controlled at 0À14-1À05 kg./cm.<SP>2</SP> (a suitable control circuit for use with an autoclave being illustrated) and may be constant or gradually increasing; it may be applied during part or all of the full bonding stage and also during pre-heating, cooling or increase or reduction of the bonding pressure. The bonded laminate may be reheated and quenched to minimize haze, and interlayer edge portions which are extruded during bonding may subsequently be trimmed.

Abstract: A gas jet emitter (20) emits, through a series of orifices (21), a row of gas jets which are diverted and spread by a deflecting plate (40). The spreading of the jets is however limited by impact with the adjacent jets, which gives rise in each jet to counter-rotatary vortices (45, 48) surrounding a laminar flow zone (44) at low pressure, into which a thin stream (S) of molten thermoplastic material is sent. The jets are directed against a main gaseous flow (18) into which they penetrate, forming interaction zones. The thin streams are thus stretched successively in two steps, but the second step may be omitted. The method applies in particular to manufacturing glass fibres. <IMAGE>

Abstract: A communications system is disclosed including a radio junction box controlling a number of radios and a number of crew boxes all linked by a ring circuit consisting of a single coaxial cable which provides both power supply and information. The various communication channels between the crew boxes and the radios and an intercom channel linking the crew boxes are provided by time division multiplexing. The microphone of each crew box is coupled to the coaxial line by a current generator. Each current therefore generates an appropriate voltage signal across the impedance of the cable which is assumed to be constant. Thus, when more than one crew box feeds current onto the line, the currents add and generate a correspondingly greater voltage signal on the line. Therefore, the attenuating effect which would take place if each crew box output were in the form of a voltage (in such a case each output would be loaded by the relatively low output impedance of the other voltage output or outputs on the line) is avoided. Time multiplexing of the crew boxes is therefore not required. Each signal transmitted on the line is pre-distorted to offset any distortion it will undergo upon transmission along the line. The signal received by each crew box is regularly clamped to effect signal separation and provide a known mean signal reference level.

Abstract: Method and apparatus for improving the operation of forced-air-cooled steam condensors having a bank of air-cooled heat exchangers connected between steam lines and condensate conduits. Air is forced through the heat exchangers by fans and shutters are provided to either discharge the spent air to atmosphere or to recirculate the spent air into the fan inlets to mix with fresh outside air. The steam pressure in the steam line is sensed along with the temperatures of the condensate in each exchanger and of outside air. The condensate conduits are in the recirculation path of spent air, and the fan is adjustable to control the quantity of air forced through the exchangers. By controlling the shutters and the fans in response to the pressure and temperatures, a highly-efficient cooling effect is achieved. According to the invention there are provided sensor-governed motor-driven roll-shutters (11), which more or less can screen the heat exchangers (12) and thereby create a recirculation channel (17) for the warmed up air, and there are furthermore provided sensor-governed adjustments of the blade angles of fans (13). The condensor (2) has an upper steam pipe-line (9) and connected thereto the heat exchangers (12), which preferably are arranged trapezoid-like in two parts covering the lower fans (13), one for each so called module, whereby a roll-shutter (11) is arranged outside of and at distance from each heat exchanger part, and whereby the roll-shutters are rolled up close to the steam pipe-line (9).

Abstract: A method for monitoring structural changes in a binder in contact with a solid object, while the binder is curing. Conductivity measuring pick-ups are placed in the binder mass and at the boundary between the binder and the solid object. A low amplitude AC voltage is applied to each pick-up at a low frequency, and the pick-up output signals are compared by a differential inductive bridge. The difference between the output signals is indicative of the extent of adhesion of the binder to the solid object. Preferably, only those components of the pick-up signals which are in phase with the applied AC voltage are employed for the comparison.
