Patent GB-802168-A (GB)
Title: Synthetic bitumen compositions
IPC: C10C3/02
Filed: 1957-01-26
Abstract: A synthetic bitumen is prepared by mixing up to 75 per cent of a dry solid carbohydrate with a catalyst of sulphur, sulphuric acid, lime, or caustic soda or potash, and an asphaltic fuel oil containing 10-60 per cent asphalt, and heating to, and maintaining at, a temperature at which polymerization occurs.  Specified carbohydrates are mono- and di-saccharides, starches, hemicelluloses, and dextrines, pure or as by-products, e.g., cane, beet, or wood molasses or waste sulphite liquor, but such by-products must be dehydrated.  The bitumen acts as a binder for broken stone, gravel, slag, shale, sand, soil (particularly adobe), and fibres, e.g., wood fibre, sawdust, paper fibre, jute, cotton linters, hemp, hair or asbestos, Other optional additions include tall oil, lignin, pigments, and sodium chloride. The bitumen may be used as such, as a cut back, or as an emulsion.

Title: Ducted centrifugal fan
IPC: F04D29/42
Filed: 1975-01-23
Abstract: So as to be able to employ, in an elongated flow duct (10), a centrifugal blower which is more powerful and produces less noise than a conventional axial blower, the centrifugal blower is disposed in such a way that the rotational axis (15) of its impeller (14) extends at an acute angle to the longitudinal axis of the flow duct (10). A casing wall (11), which contains the inlet port (12) of the blower, is designed as a partition in order to subdivide the flow duct (10) into a suction side and a discharge side. The inlet port (12) is approximately funnel-shaped, but with a radius of the funnel-shaped region which is greater towards the centre of the flow duct. It opens out into an inlet (13) assigned to the impeller (14). The impeller (14) is surrounded by a spiral-shaped chamber (18) which downstream in the direction of the longitudinal axis of the flow duct (10) opens out into an outlet (20). <IMAGE>

Title: Hydraulic control valves
IPC: B23B47/22
Filed: 1958-02-05
Abstract: 870,592. Hydraulic control systems. TYDEMAN, C. W. Feb. 5, 1958, No. 3785/58. Class 69 (2). An hydraulic control device for machine tools and the like comprises a valve body 14 having a bore 36 in which directional control means 38, 40 are mounted for reciprocating movement and are operative in one position to connect an intake conduit 32 leading from a source 18 of hydraulic fluid and a drain conduit 110 to first and second conduit means 100, 102, respectively, connected one to each end of a cylinder 20, and in a second operative position to connect the intake conduit to the second conduit and the driven conduit to the first conduit. The directional control means consist of spools 38, 40 urged apart by a spring 48 and individually moved to their alternative positions by solenoids 42, 44. In the position shown, a piston 22 carrying a tool 24 is moved in the direction of the arrow by energization of the solenoid 44, the spools connecting conduit 32 to conduit 100 and conduit 110 to conduit 102 by means of conduits 72 and 104 and a by-pass valve 76 which, in one position, connects conduits 72 and 104 to conduits 100 and 102, and in an alternative position determined by energization of a solenoid 78 interconnects conduits 100 and 102 to permit the piston 22 to be manually or mechanically adjusted to position the tool relative to a workpiece 112. Reverse movement of the tool is effected by de-energizing solenoid 44 and energizing solenoid 42, the fluid from intake conduit 32 passing through a conduit 106 to the conduit 104. Energization of both solenoids 42, 44 connects the intake conduit to a conduit 114 which is closed by the spool 40 and provides a stand-by condition for the tool. Deenergization of both solenoids connects the conduit 104 to conduit 114 leading to a second drain conduit 62, which is connected directly to the sump 16, for rapid return movement of the tool. The drain conduit 110 is connected to a pressure regulator 108 consisting of a spring- controlled piston and cylinder arrangement. Fluid through the regulator passes to a conduit 126 to one or more bleed valves 128 having tapered V-shaped grooves 148 controlling the flow through orifices 150 connected to conduit 154, the valves being rotatably adjusted by graduated drums 142. Flow through each bleed valve is controlled by solenoid-operated valves 130 which in one position permit the fluid to pass through its respective bleed valve to a conduit 34 leading to a sump 16, and in the other position stop the flow of fluid through the bleed valve. The bleed valves may be of the same or different sizes and any combination may be used to obtain a desired rate of flow and speed of movement of the piston 22 and tool 24. Leakage past the end of the spools is prevented by 0-rings and grooves around the spools connected by radial and axial passages in the spools to a driven pipe leading to the sump.

Title: Improvements in and relating to adjustable beds and the like

IPC: A61G7/002
Filed: 1960-02-03
Abstract: 878,597. Adjustable beds. DURA CORPORATION. Feb. 3, 1960, No. 3787/60. Class 52(2). [Also in Group XXIX] Two bed-operating double-acting hydraulic motors are interconnected by solenoid operated valves and a reversible pump that, by the operation of electrical switches alone, a single reversible electric motor can be used to operate either hydraulic motor separately or both motors together. As shown, a double-acting hydraulic ram 44 is pivoted at 46 to a stationary frame 10 and controls the angle of inclination of a U- shaped back-rest frame 20 pivoted at 26. The piston rod 42 of the ram acts on bell-crank lever 40 to turn shaft 32 and rotate frame 20 by means of connecting links 38. A second hydraulic ram 76 operates a foot section 56, Fig. 2, through a similar bell-crank lever 72 and links 82. The part 58 of the section is connected by pivots 88 and links 64 are constrained to lift the end 24 to about the level of the pivots 88. The rams 44 and 76 are operated by power unit 48 which consists of a reservoir, reversible pump and electric motor. In one direction of rotation of the motor the pump output enters lines 50 and 78 and in the other direction, the output enters lines 52 and 80. Solenoid operated valves are mounted in the cylinder heads of rams 44 and 76 (see Group XXIX) and the fluid cannot enter the cylinder to operate the ram piston until the appropriate solenoid or both solenoids are energized. A pushbutton switch control assembly, 142. Fig. 8, is connected with the forward and reverse field coils 178 and 176 of the motor and the solenoids of the valves in rams 44 and 76. The four buttons, when depressed, hold the switches 212, 214, 216 and 218 in the dotted line position. The circuit through the motor field coil 178, established by depressing switch 216 or 212, is broken if either switch 218 or 214 is simultaneously depressed. Neither can field coil 176 be energized by switches 218 and 214 while either switch 216 or 212 remains depressed. Depression of each switch operates a valve solenoid through lines 162, 202 and 210, 160.

Title: Method of honing gears

Filed: 1960-02-03
Abstract: 884,844. Gear - finishing. NATIONAL BROACH & MACHINE CO. Feb. 3, 1960 [March 23, 1959], No. 3817/60. Class 83 (3). A method of honing a gear at crossed or parallel axes consists in using a gear-like tool such that the teeth of the work gear engage the bottoms of the tooth-spaces of the tool. The tool may be made of equal parts of an epoxy resin and a silica filler, with an aliphatic polyamine, such as diethylene triamine, as an accelerator. The gear G, on a table 42 pivoted at 48, is raised into contact with the tool H by a fluid-pressure device 68 the piston of which may be held by a fluid-pressure operated friction pad while relative traverse is effected along the gear axis. The radial force between the gear and hone may be up to 125 lbs. and is mostly taken by the engagement between the tops of the gear teeth and the roots of the hone teeth. The diameter of the hone is reduced periodically, to prevent the tops of the hone teeth contacting the bottoms of the gear tooth spaces. The hone is rotated to give a pitch line velocity of about 850 <SP>1</SP>/min. The gear acts upon the hone somewhat as a crushing roller to maintain the correct shape of the hone. Until several gears have been finished, the hone may not contact the bottom of the gear tooth spaces.
