Title: Improvements in and connected with actuating mechanism for fluid pressure controllers, governors and the like
IPC: F15B9/08
Filed: 1920-08-09
Abstract: 170,698. Stone & Co., Ltd., J., and Davis, S. L. B. Aug. 9, 1920. Pilot-valve apparatus.-A servo-motor device particularly applicable for operating large flat or D valves or the eccentric track of hydraulic motors or pumps, of the type wherein a rotor body is formed with cylinders having pistons engaging an eccentric track, comprises a differential ram controlled by a slide valve mounted on it and adapted to be moved transversely to it by an inclined guide actuated by hand or automatic means so that the subsequent movement of the ram restores the control valve to its neutral position. The ram e, which is connected at e<2> to the apparatus to be actuated, has a large part e<1> adapted to work through a packing f<1> held in position by a closed cap g, and a smaller part e adapted to work through a packing f held in position by a perforated spigot h' on a detachable member h provided with a stuffing-box k for the ram. The control valve 1 slides in a groove in the ram and is held against a seat r by a spring 5 housed in sockets on the back of the valve and in a member having a face 4 bearing against a detachable cap 6 fitted with a packing 8. The valve seat has ports q, t whereby fluid pressure entering at n may be admitted through a duct p to the large end of the ram or passed to exhaust w through ducts p, s, z. The control valve is actuated by a bridle 9 having an inclined slot equal in length to the travel of the ram and held against a flat on the ram bv the cover 6. In the form shown, the control valve is actuated by a ram d connected to the bridle and adjustably loaded by one or more springs 23, 23a acting through a rod 20 and lever 14 linked to the casing at 18 and provided with an adjustable abutment 16. The linked end of the lever may be spring supported. The ram d may be replaced by any mechanical moving part or by a hand-actuated rod balanced if desired by passing it out at both sides of the casing. The hand-lever may work in a quadrant and be fitted with locking-means, and may be acted on by springs to return it to its initial or to an intermediate position.

Title: Improvements in or relating to frequency modulated communication systems
Inventor: GUANELLA GUSTAV
IPC: H04B7/165
Filed: 1951-10-09
Abstract: 698,018. Automatic frequency control systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 9, 1951, No. 23513/51. Class 38 (iv). [Also in Group XL (c)] A self-excited high-frequency re-transmitter 14 of a radio relay station is constrained to follow the frequency modulation of the wave received at the station, by heterodyning both waves to the same mean intermediate frequency and utilizing the phase variation between these intermediate frequencies to regulate the instantaneous frequency of the self-excited source 14. As shown, the F.M. wave received on the aerial 10a is mixed at 10 with a heterodyne source 11, and the resulting IF is amplified at 12 and applied as one input to a phase-comparing balanced bridge 13. The other input to the bridge is an I.F. derived by mixing the output of the self-excited magnetron 14 with a second heterodyne source 17 in the mixer 16. The bridge output is applied to a frequency control element 15 associated with the magnetron 14; this element may comprise a thermionic reactance valve, or, as shown, a splitanode magnetron 40 operating as a variable capacity coupled into the cavity of the magnetron oscillator 14 through the loop 38. The change in the mean frequency of the relayed F.M. wave is determined by the difference between the frequencies of the heterodyne sources 11, 17. These may be independent crystal-controlled sources, or their frequencies may be derived by frequency conversion or multiplication from a single source. If the output carrier from the source 14 is of the same frequency as the input carrier at 10a, the same source 11 serves for heterodyning both.

Abstract: 1420591 Twistlocks E C COLE 21 Dec 1972 [29 Sept 1971 19 May 1972] 45252/71 and 23572/72 Heading E2B In a twistlock of the kind comprising a bolt 120 having a shaft 122 mounted for axial movement in a hollow housing 104 and rotatable about its longitudinal axis, the bolt having a head 124 provided with at least one radial projection and being movable between a withdrawn position in which the head is inside the housing, a release position in which the head is outside the housing and a locking position wherein the head is outside the housing and has been rotated so that the or each radial projection extends in a direction different from that in which it extends when the bolt is in its release position, axial movement of the bolt from its withdrawn to its release position is effected by linear movement of a bolt operating means 169 disposed externally of the housing and below the head, and clamping means is provided and which is operative, when the bolt is in its looking position, to cause the or each projection to be tightened against the base of a corner fitting of a freight container. As shown, the bolt 120 is fully retractably into the housing 104 and adjustable for various thicknesses 102a --- 102c of corner fitting by a clamping nut 162 screwed on the shaft 122 and provided with arms 166 between two of which, when the bolt is in a locking position, is disposed a locking peg 174. The shaft is slidable in a spacer sleeve 132 the lower end 138 of which is engaged by a catch 152 to retain the bolt in the release position thereof. Rotation of the bolt by the handle 169 to the locking position causes a pin 136 carried by the shaft to displace the catch, against the bias of a rubber pad 154a so that when the bolt is again turned to the release position the bolt and sleeve can move downwardly by gravity to the fully retracted position; the pin is engageable in grooves in the end 138 of the sleeve in both the release and locking positions of the bolt. A compression spring 168 which urges the head 124 towards the housing is capable of being compressed into a solid condition to form a washer and the sleeve is urged by a spring 140 towards the pin 136.

Abstract: 1456873 Controlling vehicle suspension height; preventing body roll NISSAN MOTOR CO Ltd 30 May 1974 [30 June 1973 4 July 1973] 23999/74 Heading B7D In a vehicle suspension system including hydropneumatic suspension units 24 which each incorporate a levelling 40 communicating through supply lines 20, 22 with a fluid pressure source 10 comprising a pump 10, a pressure control valve 14 and an accumulator 16 and with a reservoir 18 respectively, communication between the lines 20, 22 and the pressure source 10 and reservoir 18 is controlled by solenoid valves 48, 50, 56, 58 energizable by a control circuit including a manually-operated switch S1 which has a normal position wherein the solenoid valves are operated to block the lines 20, 22 and inhibit levelling operations whenever a sensor 42 indicates that the vehicle body is tilted by an excessive amount, and has a jacking position wherein the return line 22 from the units 24 is connected to the pressure source 10 so that all the units are extended to raise the vehicle body for servicing or repair. The sensor 42 is a pendulum switch having a movable contact in the form of a pendulum 52 which can swing between stops 56 to co-operate with a fixed contact 54. The pendulum 52 may be disposed to respond to either roll or pitch of the vehicle body and when a predetermined value is reached an electrical signal is sent through a delay circuit 44 which filters out unwanted transient effects to a transistor control circuit 46 which energizes a relay coil 62. When a movable contact 64 of the switch S1 is in the normal position engaging a contact 66, switch contacts 62b, 62e moved by the coil 62 energize the coils 49, 51, 57 of the values 48, 50, 56 so that the valves block communication between the lines 20, 22 and the pressure source 10 and the reservoir 18. When the movable contact 64 of the switch S1 engages a contact 68 the coils 51, 57 of the valves 50, 56 are energized so that both lines 20, 22 are connected to the pressure source 10. The contact 64 may also be moved into engagement with a contact 70 for connecting both lines 20, 22 to the reservoir 18 so that all the units 24 are retracted to lower the body, or with a contact 72 for energizing a coil 60 to open a switch 60a which disables the coil 62 in the event of a failure in the system. In another embodiment, the four solenoid valves are replaced by a single valve assembly.
