IPC: F15B5/00
Abstract: 1,053,943. Fluid actuation of switches; thermal switches. AMERICAN AIR FILTER CO. Inc. June 28, 1963, No. 25865/63. Heading H2B. A control switch of the type wherein a movable contact is moved between two fixed contacts by variations in fluid pressure, temperature, or mechanical or electrical pressure, has the two fixed contacts mounted on respective carriages which are adjustable in unison to determine the operating points of the switch and are relatively adjustable to set the switch differential. The casing 25 of the fluid-pressure switch illustrated is secured to a mounting plate 30 and carries two guide rods 35 on which rectangular plates C and D are slidingly supported and carry respective contact arms 50 and 60 by means of insulating posts (Fig. 5, not shown). The ends of arms 50 and 60 form fixed contacts 10 and 12 respectively on either side of the stirrup-shaped moving contact 20 attached to a diaphragm 18. A spindle 70, engaging the carriages C and D by means of threads 71 and 72 of opposite sense, is carried in a support plate E and extends outside the casing for rotation by a screwdriver in slot 97. This varies the spacing between contacts 10 and 12 and hence controls the switch differential. The plate E is slidable on rods 35 by means of the threaded portion 81 of a sleeve 80 coaxial with spindle 70 and rotatable by a knob 95 having a pointer 96 co-operating with a range scale on mounting plate 30. Collars 73 and 74 on spindle 80 ensure that it moves with plate E and thus moves both carriages C and D in unison to alter the range setting of contacts 10 and 12. The casing may be sealed or have a breather hole 27<SP>1</SP> as required. Springs 90 and 91 are provided to take up back-lash. Instead of diaphragm 18 a bi-metallic element may move contact 20.

Abstract: 1,072,517. Making filter medium. JOHNS-MANVILLE CORPORATION. Oct. 12, 1964 [Jan. 2, 1964], No. 41478/64. Heading BIT. [Also in Division Dl] In a process for producing a felted body from attenuated glass fibres, a stream of hot gases carrying the fibres is separated into two parts of which one comprises a substantial proportion e.g. 45% of the gases but a small proportion of the fibres, whilst the other comprises a substantial proportion e.g. 99% of the fibres. A heat-curable binder is then introduced into the latter stream, and the fibres in it are collected to form the body. As shown, glass is melted in a chamber 10, drawn into primary filaments 12, and attenuated into fine fibres 15 by a blast of hot gas from the burner 14. The fibres are carried by the gas into and through the tube 35, which is bent so that the fibres are deflected as shown. Part of the tube 35 is surrounded by a heatexchanger 11, to cool partially the gas stream. A divider 72 divides the outlet into two parts 74 and 76. Part of the gas and substantially all of the fibres emerge at 74 and are sprayed with liquid binder, e.g. a phenol-formaldehyde resin, from a nozzle 46. The fibres are collected on a foraminous belt 38 with the aid of a suction box 41. Gas from the diversion discharge nozzle 76 contains few fibres and passes to chamber 77 where heat may be recovered from it. The fibres in it are removed by a cyclone device 75. The mat 40 of fibres is removed from the belt 38, passed through an oven 52 to cure the binder and rolled up. In other embodiments; (Fig. 2, not shown) the tube 35A is divided near its outlet end, from one arm part of the gas and most of the fibres emerge and are collected as in Fig. 1, the few fibres passing into the other arm are removed by a foraminous belt and collected in a bin; (Fig. 3, not shown) the discharge nozzle 74B for the fibres is above the diversion tube 76B and empties into a chamber 90, the few fibres in this stream fall to the bottom of the chamber, and can be collected; (Fig. 4, not shown) a rotating foraminous member 100 is placed in the tube 35C, diverted air is drawn off through it, any fibre fines collected on it are blown off by cold air and so returned to the main stream of fibres; (Fig. 6, not shown) air is discharged into the tube 35D at its first inflexion to obviate friction between the fibres and the wall of the tube; (Fig. 8, not shown) several burners may be mounted side by side, with a conveyer tube 35 for each, feeding the fibres to a common collection belt; (Figs. 9 and 10, not shown) the divider 72 is adjustable to vary the relative volume of air to be diverted; (Fig. 11, not shown) the divider 72A has ports through which air is blown to remove any fibres that may collect upon it; and (Fig. 12, not shown) the divider 72B is a cylinder rotated either by the air stream or by external means so that any fibres that may collect on it are projected back into the main fibre stream. More than one separation point may be incorporated.

Abstract: 1,225,421. Transistor inverters. WESTERN ELECTRIC CO. Inc. 19 March, 1968 [29 March, 1967], No. 13202/68. Heading H3T. In an inverter including switching transistors 13, 14 having a transformer 22 providing regenerative feedback from the emitter-collector path to the emitter base path of the transistors, a series resonant circuit comprising an inductor 23 and a capacitor 24 are connected in series between the primary winding 22-1 of the transformer 22 and the input 10 so as to provide a starting wave train of magnitude sufficient to overcome the residual magnetization of the transformer core and the series resonant circuit has a resonant frequency such that it presents an impedance at the operating frequency of the inverter sufficient to isolate the series resonant circuit from the operating frequency determining means 19-3, 20, 21 and 22-1. When switch 12 is closed a damped sinusoidal voltage occurs in the resonant starting circuit 22-1, 23 and 24. The first half-cycle of this may be positive which may increase the residual positive flux in the transformer 22 so as to drive it into saturation. The feedback from the transformer is insufficient to cause the transistors to conduct. As soon as the starting transient has passed through its positive peak and reverses towards its negative peak the magnetization in the transformer changes to a negative flux to produce a starting impulse to turn ON transistor 13 and cut OFF transistor 14. The current now flows through primary 19-1 of the output transformer 19 which is coupled to the starting circuit via 19-3. This causes the tunable tank circuit 19-3, 20, 21, 22-1 to start oscillating and maintain the regenerative feedback to the transistors 13, 14 which conduct alternately. The frequency at which the starting circuit 22-1, 23, 24 oscillates is lower than that of the inverter so that the starting circuit becomes isolated from the inverter when in operation. The frequency of the inverter may be varied by an adjustable inductance transformer 21 or through synchronizing signals applied at 21. Alternatively, synchronizing signals may be fed to other inverters via transformer 21. Resistor 18 provides a discharge path for capacitors 16, 17, 24.
