Abstract: 962,782. Electrical transformers. WESTINGHOUSE ELECTRIC CORPORATION. Jan. 18, 1963 [Feb. 13, 1962], No. 2277/63. Heading H1T. A transformer has first and second windings 410 and 420 (Figs. 6 and 7), comprising insulated turns of conductive strip material, the first winding 410 being made up of first and second winding sections 410A and 410B, at least a portion of which are wound together to provide a predetermined capacitance 432, the inner end of one of the sections (410A) and the outer end of the other (410B) having terminals for connection to a circuit, the other ends being left unconnected, and both ends of the second winding having terminals L401 and L402. The series capacitance so provided may compensate for at least a part of the inductive drop in the supply line as well as the drop in the transformer. The thickness of the conducting path is varied in steps by varying the number of layers of conducting strip according to the current flow in the parts of a winding section. The turns of the second winding 420 are interleaved with the portion of the winding section 410B which is not interleaved with the winding section 410A, hence providing a capacitance 434 between 410B and 420, which may compensate for the reactive voltage drop due to the exciting current. The end of 410B, with which 420 is interleaved, is connected to 420 (e.g. both may be earthed, 492) so as to provide a charging path for the capacitance 434. The second winding 420 may be in two sections, which can be connected in series or parallel, and may have one or more sections formed of conductors other than sheet.

Filed: 1973-01-17
Abstract: 1423373 Photo-electric measurement HUNTER ENG CO 17 Jan 1973 2372/73 Heading G1A The angular disposition of a body relative to a reference line is measured by sweeping a light beam across the line from a source on the body and detecting when the beam is along the line to gate a signal generated in accordance with the beam angle to a display, the gating only being operative for one sweep direction.  To measure the toe of vehicle wheels, frames  25, 25A adjustably mounted on respective wheels are aligned to define the reference axis R. Each frame contains a photo-cell 61, light source 50 and a lens assembly oscillated in a horizontal plane by an electric motor 35 and eccentric cam 39. A chopper disc 44 produces light pulses at 1KHz to reduce extraneous light interference and a potentiometer 42 driven through 1:1 gears produces a ramp output proportional to beam angle. The photo-cell outputs are amplified (62), Fig. 10 (not shown), sharpened by a monostable and differentiator and fed to a comparator which only passes pulses occuring in one sweep direction to a gate allowing the ramp voltage at that instant to be displayed and held in a memory until the next  reading.

Filed: 1930-01-27
Abstract: 338,443. Happel, O. Jan. 27, 1930. Forced ventilation; air, heating and conditioning. - In a method of heating a hot-house, air from the hot-house, with the optional addition of fresh air is drawn with relatively high velocity through hot-water or steam heaters, the condenser apparatus of a power-house preferably forming the source of heat, and is returned to the hot-house through underground chamber, said chambers preferably having openings at the top in order that a portion of the hot air may pass into the hot house through the soil, which is thereby heated and aerated. As shown in Fig. 6, a blower 7 draws air through heaters 5 into flues 12 from which it passes through chambers 11 roofed with slabs 3 of ferroconcrete, preferably porous or perforated, upon which the soil 4 is placed. The chambers 11 communicate with return flues 12<1> roofed with grids 15 for the return of the. air to the atmosphere of the hot-house. The walls of the supply flues 12 are based on the levelled subsoil or on a dressing of ash applied thereto and their roofs may be formed as paths for trucks and the like. Each chamber 11 may be partially or wholly cut off by means of dampers. A ventilating shaft 17 with dampers 18 allows a quantity of fresh air to be drawn in, this addition being balanced by the normal leakage of air from the hot-house. The air may be humidified by water sprayed on to the heaters by sprayers 19. Each heater has a nest of quincuncially disposed tubes of elliptical cross section at the middle portion, Fig. 5, and with cylindrical ends adapted to fit, into water chambers. When supplied with hot water or steam from a power house, the ordinary condenser may have in parallel with it a water cooled condenser, the water from which is pimped through the hot-house heaters, or, alternatively the heaters themselves may be used as supplementary condensers. In a modification, Fig. 9, a mixing chamber 7<1> communicating with an air shaft 17<1> is disposed between the heating elements 5 and the blowers 7. Admission of fresh air into this chamber is controlled by a damper 18<1> and the admission of air from the hot-house by a damper 22<1>. In hot weather the damper 18' may be opened and the heaters partially or wholly cut off, the blowers then serving merely to ventilate the house.

Title: Improvements relating to explosion protection systems and to pressure detectors for use in such systems
IPC: A62C99/00
Filed: 1953-02-04
Abstract: 786,871. Actuation of switches. GRAVINER MANUFACTURING CO., Ltd., MATHISEN, A., and WILKINSON SWORD CO., Ltd. Feb. 1, 1954 [Feb. 4, 1953; April 1, 1953; July 20, 1953], Nos. 3161/53, 9080/53 and 20135/53. Class 38 (5). An explosion protection system is adapted to respond both to a predetermined pressure, however slow the onset of this may be, and to a predetermined rate of rise of pressure. Preferably a single member such as the diaphragm 11, Fig. 1, is caused to move by either of the above conditions to close a circuit, e.g. through contacts 19, to bring into action means for suppressing, relieving or diverting the explosion. In Fig. 1, the increasing pressure acts upwards on a diaphragm 12 so increasing the pressure of fluid between the diaphragms 11, 12, but a bleed hole 11b allowing escape of fluid prevents movement of the diaphragm unless the rate of rise of pressure is sufficient or unless the final pressure on the diaphragm 12 is sufficient to bring a projection 12a into engagement with the contact 11a on the diaphragm 11 and move it upwards. In a modification, Fig. 2 (not shown), a bellows replaces the diaphragm 124 the diaphragm 11 has a snap action, and in another modification, Fig. 4 (not shown), both diaphragms are replaced by bellows, the contact-carrying one being more flexible than the other, which may be reinforced by a spring, Fig. 5 (not shown). In a further modification, Fig. 6, the bellows are filled with liquid instead of gas and a third bellows 75 is provided which communicates by means of an orifice 74 with the bellows 70 to which the changes of pressure due to the explosion are applied. The bellows 75 is more flexible than the bellows 72 and therefore on a slow rise of pressure it alone moves until a stop 76 is encountered after which bellows 72 expands to engage the contacts 73. With a quick rise of pressure bellows 72 responds immediately since the orifice 74 cannot pass fluid quickly enough. In a modification the bellows 72 and 75 are equally flexible and the bellows 75 carries a pair of normally open contacts, the lower of which can be engaged by a stud on the top of bellows 72. With slow rise of pressure both bellows 72, 75 expand equally till the upper contact engages a fixed contact. Further movement then causes the contacts to engage. With a quick rise of pressure, bellows 72 expands more quickly than 75 and its stud presses the contacts into engagement. Specifications 643,188, 702,919, [both in Group XXI], 719,622, 749,583, [Group XXI], and 786,872, [Group XXIX], are referred to.
