Abstract: An air brake system for a vehicle includes both automatic braking and direct braking. The equipment for direct braking requires the installation of a main air reservoir pipe in the longitudinal direction of a train. A single pipe serves both as the brake pipe for automatic braking and as the main air reservoir pipe for direct braking. A control valve for automatic braking is connected to the air pipe via a pressure-adjust valve for adjusting the pressure of the air supplied to the control valve to a specified value, and via a check valve arranged parallel thereto. An air pipe supplying the pressure from the control valve to the brake cylinder and an air pipe supplying the pressure from the direct brake equipment to the brake cylinder are respectively connected to the brake cylinder via a double check valve.

Abstract: The present invention relates to improved heat insulating particles with a high heat insulating effect and high mechanical strength. The particles are smooth cells formed around hollow or solid grains of a low heat-conducting material such as silica, alumina, glass, or a synthetic resin like nylon or teflon, which are coated with a material that can readily reflect the heat radiation such as aluminum, copper, gold, silver, stainless steel or titanium. The cells thus-formed are bound together by sintering in the form of a block or any other desirable shape so that the metallic surface cells are bonded together at their points of contact through molecular dispersion of the metal molecules of the respective surfaces.

Abstract: There is disclosed a set of current collecting elements used for a current collecting roller which feeds current to a transportation apparatus. The set of current collecting elements comprises a plurality of electroconductive elements arranged in juxtaposed relation to one another, said electroconductive elements being tightly and rigidly secured to each other by a lead wire at the lower portion of said elements.The current collecting roller using the present sets of current collecting elements is protected from being damaged by heat being generated between current collecting member and each of the electroconductive elements.

Abstract: A system for issuing instructional signals to individual cars of a train for causing actuation of a device such as a container locking device of the individual car. A plurality of instructional signal lines and a plurality of feedback lines extend through each car in a direction parallel to the direction of travel of the car, the number of lines being at least as great as the number of cars in the train. The one ends of the lines are connected to terminals at one end of each car in positional correspondence with the lines, and the other ends of the lines in each car are connected to terminals offset by one from the terminals in positional correspondence with the respective lines. The other end of the line on one edge of each array of the plurality of lines extends across the array and is connected to the terminal in positional correspondence with the line on the other edge of the array. The terminals in adjacent cars are connected.

Abstract: A control method for charging ready-mixed concrete additives batchwise which aims at keeping the slump of ready-mixed concrete within a certain range and making longer transportation by truck mixer possible without degrading the quality, where the slump of ready-mixed concrete is detected electrically as a change in the mixing torque so that, when this detected value reaches a value set beforehand, a motor receives a control instruction to charge additives for adjusting slump into the ready-mixed concrete and so that the operating time of the motor for charging additives and the interval until control operation is reset may be adjusted with a timer.

Abstract: There is described a control device particularly suitable for use in the construction of buildings such as continuous girder or truss bridges, elevated highways and the like, for the purpose of controlling vertically imposed loads, more particularly, for the purpose of attenuating mechanical vibrations or impacts as will be caused by braking or starting land vehicles or earthquakes, dispersing horizontally an acting forces at the joint of an upper structure of a bridge such as a girder and a lower structure such as a pier, particularly at a fixed shoe (bridge bearing) on the pier.

Abstract: A styrene-butadiene-styrene block copolymer containing 50 to 70% by weight of butadiene can be used as a base material of an element capable of detecting leakage of petroleum products by detecting to the change in an electrical signal. By use of this detecting element any leakage of petroleum products from a transportation pipe line may be detected and located quickly and precisely.

Abstract: The present invention relates to a cargo transfer apparatus of load-shifting type. The load-shifting type cargo transfer apparatus according to the present invention consists of a stationary unit and a mobile unit. The stationary unit comprises a series of equally spaced parallel projections of equal width and height. The mobile unit comprises a main frame of a hollow square section with a rectangular top, and a support equipped with a plurality of tines integrally attached like comb-teeth at equal intervals perpendicularly to the longitudinal direction of said main frame, the tines having a H-shaped cross section and having rotatable rollers fitted to a plurality of shafts fixed at both ends to both ends of the underside of the tine at the same height. A cargo holder covers the top and both side surfaces of the tines in their longitudinal direction and has elliptical guide holes to engage a plurality of knock-pins provided at equal heights on the upper sides of tines.

Abstract: A method of and an apparatus for detecting the all make busy state of a line concentrator or an exchange in which all outgoing circuits are divided into a plurality of groups, at least one circuit is specified from each of the groups, the specified circuits are successively scanned with a scanning signal producing therefrom a plurality of phase pulse signals having phase ranges resulting from dividing phase ranges by at least the number of the specified circuits of the groups corresponding to the latter phase ranges which are one period of the scanning signal divided by the number of the groups, the busy state of the specified circuit of a group is detected to decide the busy state of the group, and the busy states of all groups at one cycle of the scanning are detected to detect the all make busy state of the line concentrator or the exchange.

Abstract: A signal checking system for use in a hardware system having a converter for converting coded input signals consisting of a plurality of bits into corresponding individual signals, wherein undesirable selection of an erroneous output and multiple outputs by the converter is detected by means adapted for checking the relation between the input to the converter and the output of a first coder connected to the converter and checking the complementary relation between the output of the first coder and the output of a second coder connected to the converter.

Abstract: A pad comprising at least one sheet of material having a thermoplastic resinous composition and a heater actuable to heat and soften the sheet, the pad being for use in alignment of machine equipment, rails, beams, girders, or other constructional elements relative to a horizontal base, vertical or inclined line, or to other constructional elements. In use the pad is placed between the equipment, rail or the like and a support or abutment therefor, and the heater is actuated so as to soften the pad just sufficiently that the weight of object or a force thereon reduces the thickness of the pad an amount equal to the desired movement of the object necessary to achieve the desired alignment.
