Title: Improvements in or relating to magnetic trigger devices
Inventor: BREWSTER ARTHUR EDWARD
IPC: H03M1/00
Filed: 1958-11-13
Abstract: 847,334. Circuits employing bi-stable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. Nov. 13, 1958, No. 36489/58. Class 40 (9). [Also in Group XL (c)] In a circuit in which a group of bi-stable magnetic cores are biased to different extents so that only one core at any time has its bias substantially cancelled by the instantaneous level of an amplitude-modulated signal, and in which the core so influenced by the instantaneous level is switched by a periodically-applied triggering pulse so as to produce an identifying output pulse, each core such as 1, 3, Fig. 1, is paired with an auxiliary core 2, 4 and the respective output windings 8 are connected in series opposition, the arrangement causing the spurious outputs produced by both cores of a pair when the signal level fluctuates in the periods between triggering pulses to neutralize each other in the output circuit. The circuit may be applied to a coder in which sampling of the amplitude modulated signal is being effected at periodic intervals by a trigger core 15 applying a triggering pulse to windings 5. The energy content of a triggering pulse is only sufficient to change the magnetic state of the main core 1, 3 in which the signal and bias currents substantially neutralize each other. Since the trigger and output windings 5, 8 are wound in opposite respects on the main and auxiliary cores forming a pair, while the signal and bias windings 6, 7 are wound in the same sense, the triggering pulse is without effect on the auxiliary core. As described in the prior Specification, the trigger core 15 is controlled by a sinusoidal voltage from a sampling source 13, and the signal and bias currents are derived from sources 9 and 10 respectively. The main and auxiliary cores of a pair may be constituted by a single ferrite ring 18, Fig. 4, formed with a radial aperture 18, the signal and bias windings 6, 7 encircling the whole structure, while the trigger and output windings 5, 8 are threaded together through the aperture as shown so as to form two separate windings around each of two magnetic flux paths corresponding to the cores 1 and 2.

Abstract: 338,018. Dehn, F. B., (Lewis, A. T., Gant, H. P., and Taliaferro, R. R.). Nov, 28, 1929. Forced ventilation; air, heating, humidifying and treating.-Apparatus for controlling the condition of the air in a room or the like, comprises a self-contained water spray chamber, a superposed air heater, and means to cause the air to pass through said chamber both in the direction of, and contrary to the direction of, the water spray and finally through the air heater. The spray chamber consists of a removable open-top tank 26 within a frame 25 upon which is mounted centrally a casing 17 carrying heating coils 16, fans 14 and air outlets 15. Air enters the tank through openings 13 and travels in the direction of and in contact with water from sprays 47, round depending baffles 48 and then contrary to the direction of the spray water, past baffles 68 for the removal of moisture, and finally past heating coils 16 to be discharged into the room. A supply of water to the bottom of the tank 26 is regulated by a float-controlled valve and from this supply water is drawn by a pump 27, Fig. 3, driven hy a motor 31 and is passed through a heater 41 with heating-coils 42 and thence to the spray nozzles 47. For regulating the humidity of the air, the temperature, of the spray water is automatically controlled by a valve 50 in the steam pipe leading to the heater 41, said valve being controlled either by a humidostat 53 located in the room or by a thermostat in the water of the tank 26. For automatically maintaining a constant room temperature, a valve in the steam pipe leading to the air heater 16 is controlled by a thermostat in the room. A screen plate 70 is provided near the bottom of the tank 26 for filtering the spray water. In a modification, the air heater casing 17 is mounted at the front of the spray chamber, the air entering through a single inlet behind the casing. The apparatus may be used for dehumidifying by shutting off the steam supply to the heater 41 and thus allowing cold water to be discharged by the sprayers.

Abstract: 758,906. Centrifugal fans. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Dec. 21, 1954 [Dec. 31, 1953], No. 36860/54. Class 110(1) A centrifugal fan comprises hollow aerofoil blades having openings through which gas can be discharged from the blade interior at a variable rate to produce a variable degree of boundary layer flow separation at the blade surfaces, for the purpose of varying the volumetric flow through the fan..Fig. 2 shows a fan having aerofoil blades 23 secured, as by welding or riveting, to a back plate 21 and a shroud 20. Compressed gas from a source 37 flows by way of a valve 33, a pipe 32 and a gas seal 27 to the space between the back plate 21 and a disc 26 attached thereto. The gas enters the interior of each blade 23 by way of a hole 35, Fig. 4, in the back plate 21 and flows out through slots 24, 25 causing flow separation as shown. The resultant reduction in the volumetric flow through the fan is controllable by means of the adjusting handle 38 of the valve 33. A scale 39 may be calibrated in terms of fan volumetric flow. In the modification shown in Fig. 3 the holes 35 are substantially nearer the fan axis than the slots 24, 25, so that gas is drawn in through the holes 35 and discharged from the slots 24, 25 by a centrifugal action, control being effected by a damper ring 40 which is carried by rods 41 slidable in bearings 42 and can be moved towards or away from the holes 35 by means of a lever 50, pinion 49 and rack 48. In a further modification, the supply of gas through the holes 35 is effected by an auxiliary fan attached to the back plate 21 and controllable by a cylinder concentric with the fan shaft and movable axially to obturate the eye of the auxiliary fan to a variable extent. Fig. 8 shows a doubleinlet fan comprising blades 23 on either side of a centre disc 66. Compressed gas from the source 37 is supplied by way of an adjustable valve 79 and an annular seal 80 to holes 77 in one shroud 20 which open into the interiors of the adjacent blades 23. Holes 78 allow gas to pass to the interiors of the blades 23 on the other side of the centre disc 66. The gas passes out through slots 24, 25 in both sets of blades. In a modification, the compressed gas is supplied through an axial bore in the fan shaft, followed by radial passages in the thickened centre disc, each radial passage opening into a transverse bore which opens at each end into blades on either side of the centre disc. A double-inlet version of the fan shown in Fig. 3 is described.
