Title: Improvements in or relating to air directing devices for use in connection with ventilating or air supply systems
IPC: F24F13/065
Filed: 1936-03-04
Abstract: 471,524. Ventilators. MARSHALL, J., and WYLIE, T. March 4, 1936, No. 6519. [Class 137] An air-directing device of the kind in which the air can be directed in any direction varying through a portion of a hemisphere for example as described in Specifications 228,440 and 282,323, [both in Class 137], is made from a mouldable organic plastic the universal mounting and the air duct containing members comprising at least two complementary parts moulded separately. The device, apart from a metal liner 2 and ring 3 of a ring assembly 1, comprises five parts, two cheek portions 5, 5a, two halves of the member enclosing the air duct 15 and the stepped ring 1, all of which are made from mouldable organic plastic. Each cheek member consists of a hollow spherical front shell 6, and a rear flat portion 7 between which and a ring 4 are webs 8, and the cheek members are held together by lugs 12 and countersunk screws, and by the rings 1, 2 and 3. The cheek members are rotated by sliding the bearing ring 4 in the ring assembly 1, 2, 3, and they form a mounting for the air duct 15 and consist of inwardly projecting rings 18 and circular bearing surfaces 19 which receive the upper and lower circular edges 20 of the duct containing member which can thus rotate in the cheek members 5 about an axis in a plane at right angles to the plane of the axis about which the ring 4 rotates. Extensions 9 mask the air passage to an amount dependent upon the angular position of the 'duct-containing member. Bars 21 are provided in the rear half of the duct. Each half of the cheek member and of the ductcontaining member is moulded in one piece, these halves being subsequently joined together. Specification 203,456, [Class 137], also is referred to.

Title: Forging machines
IPC: B21J7/16
Filed: 1973-02-09
Abstract: 1365654 Forging MASCHINENFABRIK SACK GmbH 9 Feb 1973 [18 Feb 1972] 6611/73 Heading B3H A control device for a forging machine of the type with a set of co-operating dies 1 driven by respective piston-cylinder devices 3, 4 includes a device 48 for measuring the position of each die and an electrical controller 46 responsive to signals from the device 48 to control a servovalve 42 in the hydraulic line to a compensating piston-cylinder device 35 to vary the quantity of hydraulic fluid in the line 21 between a pistonpump 22 and the piston-cylinder devices 3, 4. The controller 46 compares the actual value of the innermost position of the die with a nominal value. The position of a piston-rod 38 of the compensating device 35 is also fed to the controller 46. A pair of transmitters 50, 58, feed signals to the controller to indicate the full retracted and fully advanced condition of the pump piston 24 which is driven by a crank 26 common to all the pump pistons of the dies. The signals from the transmitters 50, 58 cause the controller to receive the signal from the device 48 when the die is innermost and to move the valve 42 when the die is outermost and the line 21 is not pressurized. The position of the pistonrod 37 of the compensating device 35 determines the volume of the chamber 34 and thus the amount of fluid in the line 21 and hence the die and stroke positions.

Title: Improvements in duplex signalling systems
IPC: H04L5/14
Filed: 1928-03-02
Abstract: 287,048. Siemens & Halske Akt.- Ges. March 12, 1927, [Convention date]. Duplex signalling. - Relates to duplex telegraphy in which currents of different ranges of frequencies are used for the two directions, the sending circuit zl for frequencies f1 - - f2 and the receiving circuit z2 for frequencies #3 - - #4 being connected to the line l by a balanced repeater a, u1. According to the invention, the circuits z1 or z2, or both, are connected to the repeater a, u1 by a bridge arrangement selective as to frequency so as to reduce the passage of currents from circuit z1 to circuit z2, or viceversa, due, for example, to imperfect balance of the bridge at all frequencies. Thus the alternating-current resistances r1, w1 of the 'bridge b1 associated with the sending circuit z1 are so dimensioned as to stop all frequencies above f2, whilst the bridge b2 stops all frequencies below f3. Amplifiers are shown at v1, v2. Fig. 2 shows the invention applied to a system using a four-wire connection, currents from line l1 passing through the repeater a1, selective bridge b1 and amplifiers v1 to line l2, while currents from line l2 pass via b2, v2, a1 to line l1. Specification 222,852 is referred to.

Abstract: 307,074. Rehillet, M. J. A., and Ecureux. A. March. 2, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Spray-carburettors.- The apparatus described in Specification 277,304 is improved by the addition of means for throttling or cutting off the fuel supply in order particularly to prevent the engine from exceeding a predetermined speed. Three methods of applying the means are described. (1) A pipe a branched from the outlet of the centrifugal fuel pump 4 leads to a cylinder b in which is a spring-loaded piston c. Movement of fuel behind the piston is permitted by a pipe j. A cock g in the pump discharge passage 7 has an arm f normally held by a spring h against a stop i. At excessive speeds the piston c is raised, and its rod e engages the arm f and throttles the fuel flow to the nozzle. The cock g may be applied to the pipe 11 shown in the earlier Specification. (2) The cock is applied to the pipe 17 near its entry into the inlet passage of pump 4. The pipe 17 is in the fuel-return passage or it may be applied to pipe 16, in which case it must normally be half-open. (3) The pipe 11, Fig. 3, supplying the nozzle leads into the casing of the valve 13 the outlet from which is controlled by a needle valve n carried by valve 13. This arrangement may also be applied to the alternative position of the casing shown in broken lines.
