Abstract: A method of constructing a gallery in which a trench is excavated and the gallery is either constructed in or lowered into the excavation. The gallery is braced internally to withstand external loads applied. Thereafter a controlled backfill is applied around and over the gallery in such manner that with removal of the bracing the backfill acts effectively to form an arch above the gallery which together with the gallery is sufficient to support the overlying covering material up to the ground surface.

Abstract: A piston type throttle valve carburetor which is provided with a pilot fuel feed system and more than one main fuel feed systems is disclosed. This carburetor smoothly responds to from light load to full load operation of the engine and can be manufactured without great working accuracy required.

Abstract: A packing for use in a steel-pipe hydraulic testing apparatus, consisting of: an annular body having an annular cut in its inner peripheral portion; a plurality of backing pieces fastened to the wall of the annular cut at a given circumferential spacing and directed in the radial direction; and a plurality of adapter pieces embedded in the inner peripheral walls of the annular body of the packing at a given circumferential spacing and exposed to the annular cut, so that the aforesaid plurality of backing pieces may be each slidable on the surfaces of a pair of adjoining adapter pieces. This packing is contracted due to a hydraulic pressure being applied to the outer periphery of the body of the packing, and as a result the respective adapter pieces will slide on the surfaces of the adapter pieces in the circumferential direction of the packing.

Abstract: A dredge profile computer for a cutter suction dredge converting the measured swing angle into the width of the cut in feet and the measured cutter-ladder angle to the depth of the cut in feet, being provided with an indicating unit to show the position of the cutter head with respect to a planar profile, and with a signalling unit to indicate the position of the cutter head by means of signalling lamps with respect to the centerline and with respect to the end of cut SB and PS, and with an adjustment and control unit presetting of warning and correction facilities.

Abstract: A lamp assembly has a reflector body formed of an injection moulded, low profile, thermoset polyester moulding composition with an integral sleeve having a stop internally of the body. A tubular bulbholder has an external flange engaging against the stop and carries a bulb. The reflector body has upper and lower paraboloidal portions of different focal length joined together by a step facing the lower paraboloidal portion. The step decreases in width inwardly from the periphery of the reflector body. The lower paraboloidal portion has a greater focal length than the upper paraboloidal portion which projects forwardly away from the rear of the reflector body to a greater extent than the lower paraboloidal portion. A mounting flange around the reflector body has a planar surface against which a lens element engages. The mounting flange is disposed between shield and the rear of the reflector body.

Abstract: A tetraalkylthiuram disulfide is prepared in a higher yield without formation of by-products by subjecting the corresponding alkali metal dialkyldithiocarbamate to electrolytic oxidation, which is carried out in a two-layer electrolytic solution consisting essentially of either (1) water and carbon disulfide or (2) water and a mixture of carbon disulfide and a halogenated alkane of higher density than water, the carbon disulfide being predominant in the mixture, by means of electrodes placed in the aqueous layer containing the dialkyldithiocarbamate. The resulting disulfide is extracted to the lower layer of the electrolytic solution and is recovered from the layer. The dialkyldithiodicarbamate can be continuously produced in situ by adding carbon disulfide and dialkylamine gradually to the aqueous layer of the electrolytic solution, which contains an alkalimetal hydroxide produced during the electrolytic oxidation of the dialkyldithiocarbamate.

Abstract: A cutter head the entire cutting width of which is divided into a few parallel cutting strips defined by respective sets of cutting knives. The diameters of the cutting circles of the knives of the different sets increase stepwise in the direction away from the log. The angle of inclinaton of the main cutting edge of the knives in relation to the axis rotation of the cutter head is large in the case of the knives defining the cutting strips placed closest to the log and small in the case of the knives defining the cutting strips placed more distant from the log.

Abstract: Cobalt or cobalt alloy composite materials reinforced with continuous silicon carbide fibers, which have a high tensile strength, a low elongation, a high Young modulus and a high tensile strength at a high temperature, are produced by filling spaces in piles of the continuous silicon carbide fibers containing 0.01%-30% by weight of free carbon with melted or powdery metallic cobalt or cobalt alloy and integrating the said fibers with the said metal.

Abstract: In a gas burner ignition device for a gas-operated refrigerator, the ignition electrode of a high voltage generating unit and the flame detecting rod of a flame detector are formed into one unit to miniaturize the device. The device comprises timer means which when the flame detector or the high voltage generating unit is out of order, operates to suspend the supply of gas to the gas burner.

Abstract: A method for transferring a liquid, particularly liquid metal, from a supply to a receiver. The transfer is carried out by means of at least one suction pump located in the receiver. The outlet of the pump is covered by the liquid being pumped. A buffer zone in shape of a two phase liquid/gas zone is established and maintained between the pump and the supply and liquid from the supply is supplied to the gas phase portion of the buffer zone by discharging the liquid from liquid phase portion of the buffer zone by means of said pump. Precaution is taken that the pump outlet is covered by liquid at all times.

Abstract: A dispensing apparatus for installation in refrigerator or refrigeration units wherein said apparatus comprises a housing, a door slidably connected to said housing, a coin or token receiving opening in said housing and said door, a door unlocking mechanism adaped to be activated when a coin or token is inserted into said opening, a coin or token exit and a guard to prevent the removal of more than the permitted number of articles, said guard being adapted to cooperate with said door such that when said door is opened said guard closes off the dispensing compartment.

Abstract: A counterweight supported on the tone arm of the record player in which a weight member making an inertial motion is movably incorporated so as to apply a damping resistance to the tone arm.

Abstract: Air is passed through the product being processed, thus absorbing solvent. The air stream is then split into a main stream and a subsidiary stream. The main stream is heated by a heater. The subsidiary stream passes through a condenser which cools it, condensing out the solvent. The main and subsidiary streams are then combined and recycled to the product.

Abstract: A flexible vehicle track section for an endless vehicle track has two parallel spaced track belts mutually connected by transverse bars which also serve for transferring drive power from a vehicle wheel to the track. Each section comprises two juxtaposed moulded track units of rubber or similar material each extending over a substantial number of bars, e.g. having a length about 0.5-2 m or more. The outer side face of the unit pad carries spacingly arranged transverse gripping ribs. Apertures with suitable guide sleeves are provided in the track unit pad between the gripping ribs for mounting the transverse bars on the side face being opposite to the ribs. The transverse bars have wing portions with arcuate convex guide cleats thereon projecting in direction away from the track unit pad. In each unit pad a tension wire cable is embedded in the rubber material in shape of an endless loop extending around the peripheral portion of the unit pad.
