Title: Improvements in or relating to reinforced concrete construction
IPC: B28B23/04
Filed: 1941-01-10
Abstract: 540,714. Reinforced concrete. SCHORER H. Jan. 10, 1941, No. 356. Convention date, Feb. 11, 1940. [Class 20 (iv)] In the production of a reinforced concrete structure in which such portions of the concrete which are subject to tensile and shearing stresses when under load are pre-compressed, units are employed each having a rod-like compression member 1 and wire tension members 3, 4 arranged around the member and placed in the mould before the concrete is poured. The tension members are looped round lugs 6 on nuts 5 through which, at one end, pass screwed bolts 7 bearing, with the interposition of balls 9, on the ends of the rods 1. The wires pass around spacers 2 and are wound in helices in opposite directions and, by tightening the bolts 7, are uniformly pre-stressed. The rods may be enclosed sheaths 10 of paraffined paper and may be withdrawn after the concrete has set and the bolts 7 released, the compressive force in the rods being transferred to the concrete. The tension wires are cut along the exterior face and the holes formed by the bolts filled with cement mortar. In Fig. 5, the compression member is formed by a number of rods 21 held together by ties 22, and the wires 23 are passed inside members 27 and over spacers 24. The ends of the wires are preliminarily held by screws 35 until the setting is corrected when cover plates 36 are placed over the wires and screws 38 tightened to hold the wires firmly between the cover plates and the body of the securing means. The screws 43 are then tightened and the wires stretched as before.

Title: Improvements in and relating to rotating wing aircraft
IPC: B64C27/04
Filed: 1944-01-10
Abstract: 580,008. Helicopters. ATHERTON, L. G., and ATHERTON, K. E. Jan. 10, 1944, No. 419. [Class 4] A helicopter comprises at least, two rotating blade systems on normally vertical shafts rotating in opposite directions and tiltable to a limited extent in the same or opposite senses in planes parallel to the longitudinal axis of the aircraft, means also being provided for adjusting the pitch of the blade systems differentially or in the same sense. As shown, two rotor hubs 3, 3a having blades articulated for flapping and relative horizontal movements are driven in opposite directions with their blades intermeshing. Each hub comprises a member 14, Fig. 8, rotatable in a member 12 secured to a tubular member 9 by which it is tiltable about bearings 10, 11. in an extension 5a of a fixed tubular casing 5 extending across the aircraft. The member 14 is driven by bevel gear 13 from a tubular shaft 7 having a bearing 11<1> within the member 12. The member 14 has bearings for three blade roots 15 each having a crank pin 24 engaging spaced plates 23 on a vertical shaft 22 which is movable axially, to vary the pitch of the blades, by a bell crank lever 17, 19 movable by a rod 16 extending through the tube 7. The tubular shafts 7 extend to the centre of the casing 5 where they are driven by chain gear engaging sprockets 8, Fig. 4. The inner ends of the tubular shafts 9 have arms 34, 34a connected by links to arms 31, 31a on bevel wheels 29, 29a loose on a transverse shaft 28 upon which a vertical column 26 is mounted, the shaft 28 being carried by a torque tube 35, Fig. 5, rotatable in bearings, not shown, by lateral movements of the column 26. A wheel 32 on the column is geared to a shaft 27 having a bevel wheel 30 meshing with the wheels 29, 29a so that rotation of the wheel 32 causes opposite movements of the arms 31, 31a and consequently also opposite rotations of the shafts 9, and fore and aft movements of the column 26 cause simultaneous rotations of the shafts 9 in the same sense. The inner ends of the rods 16 are connected to a link pivoted to an arm 36 on the torque tube 35 so that transverse movements of the column 26 cause opposite changes of pitch in the two sets of rotor blades. Adjustments of pitch in the same sense are effected by an additional manual control acting upon a linkage interposed between the arm 36 and the ends of the rods 16 by which the latter may be moved simultaneously outwards or inwards. The chain gear is driven by a hydraulic motor through a free wheel clutch, the motor being driven from a pump coupled to the engine which is movable by screw gear longitudinally of the aircraft to trim it to suit the load distribution. The connection between the pump and motor is flexible to allow for such adjustment. The free wheel clutch enables the rotors to continue to rotate, when suitably adjusted in pitch, upon failure of the engine.

Title: Improvements relating to tyre-pressure regulating apparatus on vehicles
IPC: B60C23/00
Filed: 1961-01-05
Abstract: 899,790. Regulating tyre pressures. DAIMLER-BENZ A.G. Jan. 5, 1961 [Jan. 5, 1960], No. 572/61. Class 144 (2). In an arrangement for controlling the tyre pressures of a vehicle in motion wherein each tyre 11 is connected via a three-way cock 19 to a supply pipe 18, containing air at a pressure which is regulated according to vehicle speed and/or load by control means 38-4, the said cock 19 is automatically moved at predetermined time intervals to place the tyre in communication with the pipe 18 for a short time to maintain the tyre at the desired pressure. As shown, the operating lever 21 of the cock 19 is actuated against a return spring 22 by a solenoid 26 periodically energized by a time-switch 33 which is electrically driven through the vehicle ignition circuit. Alternatively the time intervals could be determined by an apparatus operated in accordance with the distance travelled by the vehicle. Fig. 2 shows the non-return valve 13 fitted to the tyre 11. The valve 13 comprises a stepped piston 45 operating in a stepped housing 52 with its small diameter end actuating the stem 47 of a valve head 48 sealing the tyre chamber 12 from the valve housing. The piston has an air passage 46 therethrough and its large diameter end is acted upon by the pressure prevailing in the pipe 17 connecting the valve to the cock 19. Normally the pipe 17 is vented to atmosphere by the cock 19 but when the cock 19 is actuated to connect the pipes 17 and 18, the pressure in pipe 18 acts on the large diameter piston end to raise the valve 48 against its spring 50 and the tyre pressure even though the latter may be greater than that prevailing in pipe 18. Equalization of pressure then occurs in the tyre and the pipe 18 via the passage 46, and when the cock 19 is restored to vent the pipe 17 the valve 48 is reseated to seal the tyre.

Title: Improvements in or relating to two-speed reducing gears, notably for washing machines
IPC: F16H9/04
Filed: 1961-01-06
Abstract: 909,285. Change-speed gear and control; belt pulleys. SOC. ESSWEIN ET CIE. Jan. 6, 1961 [Jan. 9, 1960], No. 673/61. Classes 80 (1) and 80 (2). A two-speed belt gear for a washing-machine comprises a horizontal drum selectiively driven through a V-belt 40 from either of two pulleys 5, 27 which have one flange 6; 28 rotatably fast with, and the other flange 4; 6 freely rotatable on a driving shaft 1, and sleeve 19 respectively, the latter being driven at a reduced ratio from the shaft 1 through a belt 24 and pulley 18, and the twospeed ratios are obtained by selective axial movement of the flanges 6, 28 into engagement with the belt 40 and other flanges 4, 26 respectively. The flange 6 and a hub 7 integral therewith are biased away from the flange 4 by a spring 11 and the flange 28 is connected to a hub 29 by pins 36 surrounded by springs 38 so that axial movement of the hub 29 is transmitted through the springs 36 to move the flange 28 into engagement with the flange 26 against the action of a return spring 36 and thereafter the pins 36 engage recesses 39 in the flange 26 to positively drive the latter. In Fig. 4 the hubs 7, 29 are selectively moved towards the engaged position by turning a control lever 44 which acts through cables 46, 47 on levers 49, 50 pivoted to the casing of a driving motor and the levers act in turn through balls 41, 43 on the hubs. In Figs. 9-11 (not shown) a single lever pivoted between the hubs is biased by a spring into engagement with one of the hubs and is rocked into engagement with the other by a centrifugal servo which is manually connected through a friction idler to the driving shaft to initiate ratio shift.

Title: Improvements in the manufacture of hose-pipes made of rubbered fabric such as fire hoses
IPC: B29D23/00
Filed: 1958-01-08
Abstract: 831,362. Hose pipes. SOC. DES ETABLISSEMENTS SIEBOLD-DOUSINELLE. Jan. 8, 1958 [Jan. 8, 1957], No. 758/58. Class 99(2). A method of manufacture of hose pipes made of rubbered fabric, such as fire hoses, consists in introducing the solution of rubber under pressure into the pipe, then evacuating it therefrom, filling the pipe with compressed air and revolving it around its axis while dispersed horizontally so as to obtain a uniform distribution of the layer of rubber upon the internal wall of the pipe. The hose pipes to be treated will normally have been impregnated externally with rubber and are disposed in parallel lines upon a platform while resting on the rotatable rollers d. The platform comprisess articulated sections e, e 1 , e 2  &c. With the platform in the inclined position shown the solution of latex is introduced under pressure from the lower end of each pipe and the air contained in the pipes is withdrawn at the upper end. When the pipes are full of latex, solution air pressure is applied so as to make the latex penetrate well into the textile material of the pipe wall. The pipes are then emptied of the latex solution. In order to accelerate the draining of the solution compressed air may be made to enter at the upper end of the pipe: The inclination of the pipes may be further increased during the draining. Thereafter the hose pipes inflated with air under pressure are brought to a perfectly horizontal position and are rotated around their axes so that the latex will be distributed in a uniform layer upon the internal walls. In the interior of the hose pipes there is produced a circulation of compressed air which becomes charged with vapour and is evacuated to the exterior. The direction of flow of the air is reversed several times. The operation may be performed in a heated enclosure such as a tunnel formed by a heat insulating casing so as to accelerate the drying. Any desired thickness of the layer of latex may be obtained by repeating several times the method of manufacture described above. Rollers d 1  allow longitudinal displacement of the pipe. They can be raised during latex injection to allow the pipe to stretch out.

Title: Pressure accumulator
Inventor: NISHIMURA SHIYUNICHI
IPC: F15B1/08
Filed: 1979-01-09
Abstract: PURPOSE: To extend the life of diaphragms by partitioning a pressure accumulator into two chambers by diaphragm to provide a chamber enclosing a compressed gas and an induction chamber operated by the pressure differentials between a liquid pressure and the atmospheric pressure for allowing the liquid to come in and go out.  
     CONSTITUTION: A valve 36 is closed by a spring 38 as the pressure at the outlet side 22 of the pump unit becomes slightly lower than the pressure switch closing pressure so that the connection between the outputside 22 and the induction chamber 24 is intercepted and the pressure of the induction chamber 24 is maintained above the valve closing pressure of the valve 36. Therefore, if the pressure of the output side 22 may reduce further, the pressure of the induction chamber 24 is maintained the same with the operating pressure of the valve unit 26 and the connected of the pump unit and the pressure accumulator 8 is intercepted. Accordingly, the pressure of the induction chamber is maintained between the operating pressure of the valve unit 26 as the lower limit and the pressure switch opening pressure as the upper limit so that the deformation of the diaphragm is limited to a narrow range, thus extending the life of the diaphragms.
