Abstract: 1,205,497. Moulding concrete building units. STRESSED STRUCTURES Inc. 23 Jan., 1968, No. 3388/68. Heading B5A. [Also in Division E1] In a method of producing a monolithic, threedimensional concrete structure having at least two adjoining slabs forming an edge or corner junction 1 through which extends a reinforcement network 6, Fig. 17, the mould cavity is defined by internal and external forms 35 and 23 respectively, Figs. 8 and 9, and the reinforcement network is located in the cavity which is then filled with a concrete which is allowed to expand and set to develop an initial bond with the reinforcing network. A relative movement takes place between the structure and at least a part of the forms before further expansion and complete setting is effected, this movement may be a partial collapsing of the forms. The forms 23, 35 are backed by stiffening ribs 25 and girders 26. The forms 23 are joined at the corners by locking means 27, 28. The tops of the form 23 are secured to the base support 34, Fig. 8, by flanges 32. The internal form 35 comprises four side forms 36 the comer parts 37 of which define a slot for a channel-shaped form 38, Fig. 9, movable by a fluid motor 39 to an extent determined by stops 46. A ceiling form 47 and bridging beams 30 are provided. Corner fillets have reinforcing bars 12, Fig. 6, to which the gridwork 6 is bonded. The eave girders 13, Fig. 16, formed by extensions of the roof-ceiling slab are each provided with reinforcing bars 14. The windows and door openings are formed by metal frames attached to the gridwork. The gridwork of the floors of adjacent rooms are interconnected as shown in Fig. 5. Electricity and water conduits are located in the mould cavity prior to casting. The building units may be stacked to form a multistorage structure. If a single storage structure is desired the ceiling form can be used as a floor form by raising the wall and ceiling unit to the appropriate extent after casting. The ceiling may have a layer of insulation e.g. of rigid foamed plastics protected by a coating e.g. of plaster coating.

Title: "method and means for ultrasonic cleaning"
IPC: B08B3/12
Filed: 1959-01-30
Abstract: A method of removing oil from oil bearing <PICT:0847451/III/1> articles and aggregate materials comprises dropping them into a solvent for oil and ultrasonically activating the solvent to the degree necessary to cause cavitation as they fall through it.  The cavitation can be detected by the method described in Specification 806,216.  The solvent is preferably made to flow upwardly as the material being treated flows through it.  The process is applicable to the degreasing of small machine parts and the recovery of oil by extraction of oil from oil-bearing materials such as clay, sand or silt.  In the Figure oil-bearing sand is dropped from conveyer 50 into cylindrical tank 10 and removed from the bottom thereof by screw-conveyer 38.  Solvent (kerosine) from tank 24 enters the system through valves 32 and 34 and flows in countercurrent to the sand, being finally removed by pump 40.

Title: Improvements in devices for distributing the loads between the various power stations of a system of mains or between the various generators of a power station
IPC: H02J3/46
Filed: 1941-03-14
Abstract: 617,234. Running generators in parallel ; automatic control of power. UNION D'ELECTRICITE, and COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. March 14, 1941, No. 3514. Convention date, July 3, 1939. [Class 38 (iv)] The separate regulators for parallel-connected generators A-C are controlled to maintain a prescribed load division by the voltage drop across impedances RA-RC carrying, respectively, a current proportional to the actual output of its associated machine, a further controlling current supplied by a device D modifying the voltage drop in all of the impedances in such a way as to ensure that the total output of the machines is in agreement with that programmed. The device D provides a current proportional to the difference between the actual and programmed powers. The values of impedances RA-RC are inversely as the power ratios of the machines so that they have equal volt drops when the load division is correct. These impedances are in series with similarly proportioned impedances R<SP>1</SP>A-R<SP>1</SP>C, through which, under conditions of incorrect division, pass currents proportional to the difference in voltage drops in RA-RC. These currents operate devices CA-CC actuating the regulators to effect correction. Similarly, the regulators are actuated by current passed through the impedances R<SP>1</SP>A-R<SP>1</SP>C by the device D.

Title: Improvements in Starting Mechanism for Internal-combustion Engines.
IPC: F02N15/06
Filed: 1916-03-11
Abstract: 100,246. British Westinghouse Electric & Manufacturing Co., (Assignees of Conrad, F., and Wilson, C. E.). April 6, 1915, [Convention date] . Turning-gear.-A pinion 12, carried by a shaft 11, passing through the armature shaft 10 of an electric motor, is moved into engagement with teeth 2 on the engine fly-wheel by an electromagnet 18 in series with the motor windings. A solenoid 19 is formed on the end of the shaft 11, which is held in its retracted position by a spring 20. To prevent undue rotation of the armature shaft during the engagement of the pinion, shortcircuited damper windings 7 are provided adjacent the field windings 6, the damper windings preventing a sudden increase in the intensity of the field upon the closing of the circuit. If the operator fails to open the circuit switch when the engine is running normally, the increase in the back electromotive force enables the spring 20 to overcome the effect of the electro-magnet and thus disengage the pinion 12.

Title: Pulse processing system
IPC: G01T1/36
Filed: 1973-01-26
Abstract: 1413204 Analysis of materials using radiation UNITED STATES ATOMIC ENERGY COMMISSION 26 Jan 1973 [17 Feb 1972] 3965/73 Heading G1A [Also in Divisions G4 and H3] Pulses too close to be resolved by succeeding equipment are separated by applying the pulses to two channels 21, 23 which clip the width respectively to wider and narrower values, the narrower channel being selected when a "pulse pile-up detector" detects excessive closeness. This enables the better noise discrimination provided by the wider pulses to be used when they are not too close. The invention is described as used in a system for continuously analyzing coal but is also suitable for borehole logging. Coal is irradiated with neutrons from a Californium 252 source and the resultant gamma radiation is picked up in a Ge(Li) or Na(T1) detector, the output pulses of which are passed through a circuit 15-27 according to the invention to a pulse height analyzer. The width clippers may be of the delay line or R C type and the gates which select the outputs from the channels may be of diode bridge type followed by an integrator to stretch the pulse width and a double delay line to make the pulses bi-polar, Fig. 2 (not shown). Automatic gain control of the output level of the radiation detector may be effected by a signal derived from the wide channel Fig. 3 (not shown). "Pile-up" of pulses is detected by utilizing the narrow pulse to set a bi-stable circuit which resets after a time delay. The outputs from the bi-stable circuit changes over the channel selection gate so that if a further pulse occurs during the delay, the narrow channel is selected. The selection gates block both channel outputs if the pulses from the detector are too large or too small Fig. 4 (not shown). The channel selection gates are also controlled by their output and by the output from the "pile-up" detector, to prevent the changeover during the presence of an output pulse.

Title: Improvements in or relating to the treatment of protein fibres
IPC: D06M13/335
Filed: 1961-02-02
Abstract: The dimensional stability and chemical reactivity of protein fibres, e.g. wool, hair and precipitated protein fibres, alone or in admixture with cellulosic fibres, and yarns and fabrics made therefrom, are improved by reacting them with an acidic solution of an aminocarboxylic acid, aminophenol, amino-aryl sulphonic acid, amides of an amino-aryl sulphonic acid or a reaction mixture containing amino acids, e.g. a hydrolyzate of protein-containing materials prepared by acid hydrolysis, and reacting them with formaldehyde in the same solution to impart to the protein molecule at least one new reactive site which in turn is capable of further reaction with other substances and continuing the reaction with the formaldehyde solution until the treated material shows a weight increase of at least 6%.  The treatment may be effected in stages by first treating the fibres with acidic solution of the amino compound preferably with heating at 90 DEG -100 DEG C. and then adding the formaldehyde solution.  The pH of the bath may be adjusted by the addition of formic or acetic acid and yarns and fabrics may be stretched either during the bath treatment or during drying.  The process may also include a steaming treatment.  The fibres may subsequently be optically brightened by treatment with anthranilic acid derivatives, proofed by reaction with dichlorobenzyltriphenylphosphonium chloride, 2,21-dihydroxy3,5,31, 51-tetrachlorotriphenylmethane-211sulphonic acid or a salt thereof or 3,4dichlorobenzene-1-(Nmethyl) sulphonamide, crosslinked by reaction with synthetic resins, e.g. urea- or melamine-formaldehyde condensation products or reacted with water-proofing, fire-proofing or antistatic reagents.

Title: Improvements in and relating to the regulation of air compressors
IPC: F04B49/24
Filed: 1934-02-07
Abstract: 423,396. Air compressors. BORSIG MASCHINENBAU AKT.-GES., A., 19, Berlinerstrasse, Tegel, Berlin. Feb. 7, 1934, No. 4097. Convention date, Nov. 1, 1933. [Class 8 (i)] A method of regulating the delivery of air compressors consists in keeping the suction valve 2 open for an adjustable part of the compression stroke. This is attained by admitting air at each compression stroke through a throttle valve 5, Fig. 1, to a piston 3 behind the suction valve 2. On the suction stroke the air trapped in the space 4 holds open the suction valve but leaks out through the adjustable throttle 5, 6, 8 until a point in the next compression stroke when the pressure has equalized, at which point the suction valve will close and allow the compressor to deliver air. The point at which the suction valve closes is determined by the adjustment of the throttle screw 8 which may be by hand or automatic. In a modified arrangement, Fig. 2, air is delivered at each compression stroke through the pipe 10, past a non-return valve 12 to pipes 11, 13 and 23 and behind the piston 3. On the next suction stroke this air is trapped by the non-return valve 12 and leaks from behind the suction valve piston 3 past controlling edges 20, 21 on a piston 15, which is controlled by a diaphragm 31 subjected to pressure derived from the air reservoir or varied by a temperature-sensitive device.

Title: A process for the production of carbide particles
Inventor: BILDSTEIN HUBERT
IPC: G21C3/02
Filed: 1967-01-27
Abstract: Carbide particles are produced by individually coating particles of a carbide-forming metal or a compound thereof other than the carbide with carbon black, packing into a crucible, heating to melting point in an O-free inert atmosphere and leaving to cool.  Carbides of U and Th (for nuclear fuels), Groups IVa, Va, VIa (e.g. Zr, V, Mo), B, Gd and Eu may be produced.  To produce nuclear fuel carbides, a solution containing U and/or Th and synthetic resin components may be sprayed to form spherical particles which are converted to oxides by heat treatment: impregnation with a solvent, e.g. a paraffin and a surfactant in petroleum ether, may be carried out.  After evaporation of solvent, the particles are rolled in carbon black, e.g. lampblack, in a drum or on a pelletizer plate.  Sub-stoichiometric amounts of carbon may be present in the starting particles.  Sufficient carbon black should be used to isolate the melt droplets from one another. The particles are heated relatively quickly in a single operation and left to cool. U-containing particles melt at 2450 DEG  C.  Carbide particles so produced are surrounded by a crystalline layer of structure similar to graphite.

Abstract: 1,131,202. Aircraft instruments. SPERRY RAND CORP. 31 Jan., 1966 [1 Feb., 1965], No. 4165/66. Heading B7W. In a head-up display in which an image of a runway is projected from a cathode-ray tube 10<SP>1</SP> into a pilot's field of vision to overlay a real runway during landing, the optical apparatus is pivotable so that the image can be projected into areas of the pilot's field of vision that cannot be covered by fixed optical apparatus. For example, at extreme angles of drift and incidence the runway image would normally be off the edge of the cathode-ray tube, and the cathode-ray tube and associated mirrors and lenses are pivoted about yaw and pitch axes to compensate for this, biasing signals corresponding to the pivoting angles being applied to the tube to maintain the runway image overlaying the real runway. This pivoting may be done manually, or by servos 36, 38 responsive to angles of incidence and drift. These biasing signals are also applied to a horizon line (63, Fig. 10, not shown) but further correcting signals are applied to this to move it in the direction of its length as the aircraft rolls, so that it remains on the C.R.T. screen even though it has finite length. Other information, for example altitude, may be displayed by the C.R.T.
