IPC: E04B2/86
Filed: 1924-11-26
Abstract: 246,949. Hurden, E., and Hurden, A. P. Nov. 26, 1924. Walls.-Buildings are constructed by erecting a series of uprights a, to which roof and floor joists and beams are secured, and concrete is cast between inner and outer facing elements of asbestos cement or similar material, the inner sheets being fixed to the uprights and the outer sheets being arranged around the outside of the uprights and anchored in the concrete. The uprights a have wood fillets f, Fig. 2, attached by nails to their inner faces and the inner covering g is secured to such fillets. The inner covering g is prevented from bulging by skirting boards k, Fig. 1, and temporary stiffening boards. The concrete is poured between each course of outer covering elements h, usually of trough-section, and the inner covering elements, before the adjacent upper course of elements h is placed in position. Vertically disposed bars having projecting bolts or pins adapted to extend over the flanges of the trough units, are employed to support the trough units in position during casting of the wall. Angle-irons v, v<1> secured to the stanchions are adapted to support the floor joists or beams in position. Metal rods r, arranged if desired in openings in the stanchions, as in Fig. 2, are adapted to reinforce the concrete filling j. The outer covering, g may be secured in position by transverse ties consisting of pieces of wire, atttacbed respectively to pins or holes in the covering and to the wood fillets and having their ends twisted together. A lining of tarred paper or a coating of moisture-proof material may be applied to the inner face of the inner lining. Wood fillets tor supporting the inner sheets may be placed intermediately of the stanchions. The stanchions may be of U, H-. or T-section, and they may be of wood, as in Fig. 5, and have dowel pins a<1> or openings for keying with the concrete. Wood stanchions are connected at the base by a girder t. Asbestos cement sheets are secured to the undersides of joists and soffits. Partition walls are formed by casting breeze concrete in a frame work consisting of asbestos cement sheets secured to light uprights.

Title: Inductive loop vehicle detector
IPC: B61L13/04
Filed: 1965-07-06
Abstract: 1,118,964. Road traffic detectors. GENERAL PRECISION Inc. 6 July, 1965 [6 July, 1964], No. 28657/65. Heading G4Q. An inductive loop vehicle detector of the kind wherein the output of a loop oscillator (11, Fig. 1, not shown) is mixed with the output of a reference oscillator (13) to develop a voltage which controls the frequency of the oscillator (13), is characterized in that a voltage corresponding to the A.F.C. voltage is stored and the instantaneous value is compared with the stored value to operate an output relay (26) when the former is less than the latter. The store may comprise a capacitor (127, Fig. 2, not shown) charged with a short time constant through a diode (125); if the input voltage decreases the diode cuts off and the capacitor discharges through a Darlington amplifier (131-133) which has a very long time constant. Thus signals due to a vehicle parked within the loop may eventually be cancelled when the capacitor (127) discharges, but if the vehicle leaves the loop the system is quickly restored to normal operation. In another mode of operation which may be selected by a switch (126), the store comprises a capacitor (142) in parallel with a resistance (143) giving a short discharge time, and the relay (26) is then operated for a brief interval during the passage of each vehicle.

In an embodiment for separating three wires, the two clamping members are identical and each has a lug to take a spring member. The clamps preferably have smooth surfaces and the bolts which clamp the two halves together fit in recesses in the surface. To dampen vibrations the spring member 40 preferably has a flexible cartridge inside the spring said cartridge containing a flowable material such as sand which preferably half fills the cartridge. The spacer is preferably of conducting material in order to keep the cables at the same potential. Reference has been directed by the Comptroller to Specification 827,743.

Title: Improvements in or relating to high-frequency furnaces
IPC: H05B6/04
Filed: 1947-10-30
Abstract: 639,608. Automatic control systems for highfrequency furnaces. RADIOTECHNIQUE. Oct. 30, 1947, No. 28982. Convention date, April 7, 1945. [Class 38 (iv)] In a high-frequency furnace using a valve generator the intensity of the heating field is stabilized by controlling the heating current of at least one of the valves of the generator in accordance with a voltage varying with the field. In the embodiment described a current transformer 1 energized by the high-frequency heating current produces a voltage across resistance R9, which is fed to a Class C detector L1, the output of which is fed to the diode L2. This diode and filter circuits C10, R16 and C11, R17 remove the 50-cycle modulating voltage to produce a D.C. control voltage across the ends A, B of a resistance, the centre of which is earthed. A manually-controlled D.C. comparison voltage, indicated by voltmeter V, is derived from potentiometer R1, fed from the power unit A2. The comparison voltage is applied in opposition to the control voltage across the points A, B and balances it when the desired high-frequency field is produced in the furnace. When the field alters, one of the relays E1 or E2 is operated by the appropriate D.C. amplifier L3, L5 or L4, L6, respectively, fed from the points A, B, respectively. The relay contacts AE1, AE2 close circuits to energize motor M in the appropriate direction to correct the high-frequency field intensity by rotating the rheostat controlling the heater current of one of the valves in the highfrequency generator. When the output of the high-frequency furnace is reduced by cutting of the heating current off one or more of the generator valves the motor M is de-energized by the opening of contact AE3 of relay E3, which is normally energized by valve L7 but is de-energized when the control voltage is reduced and the comparison voltage cuts off valve L7. When the high-frequency current is cut-off, the switch G is opened to cut off valve L7 and open contact AE3, the switch being a delay-action mercury switch which introduces a time lag upon reconnection into the circuit.

Abstract: 502,752. Sweetening hydrocarbon oils. STEVENS, A. H. (Phillips Petroleum Co.) Oct. 23, 1937, No. 29006. [Class 91] Hydrocarbon oils containing mercaptans are sweetened by first removing hydrogen sulphide by any known method and then mixing with a gas containing free oxygen and contacting the liquid oil with an' adsorbent impregnated with a maintained solution phase containing cupric and chloride ions. Suitably, air is 'dissolved continuously in a stream of the oil passing to a filter packed with adsorbent impregnated with a solution of cupric chloride or of sodium chloride and copper sulphate. If the solution dries, water is added to the stream of oil, e.g, by injecting the desired proportion of steam; if the solution becomes diluted, e.g. when treating wet gasoline, air at 150‹ F. is passed through the filter or the adsorbent is removed and exposed to the atmosphere until the solution is again of the desired strength. Oils treated include gasoline, solvent naphtha, and liquefied petroleum -gases. Adsorbents specified are fuller's earth, charcoal, silica gel, alumina, and pumice. It is stated that the reagent is automatically renewed and remains active indefinitely or for a prolonged period.
