Title: Improvements in or relating to control systems for the sequential operation of two or more fluid-pressure operated piston and cylinder assemblies
Inventor: HALL RICHARD WILSON
IPC: F15B11/20
Filed: 1953-05-07
Abstract: 781,284. Engine valve-gear. UNITED STATES METALLIC PACKING CO., Ltd. July 12, 1954 [May 7, 1953], No. 12702/53. Class 122 (2). [Also in Groups XXVIII and XXIX] The Provisional Specification describes a fluid pressure operated piston engine having valve gear comprising a main distributing valve 10 actuated by pressure fluid controlled by pressure-fluid operated differential pilot valves 37, 38 controlled by movement of the engine piston 33 relative to ports 32, 32<SP>1</SP> in its cylinder 22. The main valve 10 comprises a piston valve 11 in a cylinder 12 having a pressure fluid inlet port 17, two exhaust ports 23, 24, two end ports 15, 16 respectively connected to ports 36<SP>1</SP>, 36 of pilot valves 37, 38, and two further ports 18, 19 each connected to one end of the cylinder 22 via ports 20, 21 and to the outer ends of one of the pilot valves 38, 37 which are connected at their inner ends to the ports 32<SP>1</SP>, 32 in the cylinder wall. Each pilot valve has a piston formed by a smaller diameter portion 27 that controls the port 36 and a larger diameter portion 30, the space between the two portions being vented through a port 35. In operation, when the main piston valve 11 is in its lower position as shown, pressure fluid flows through the port 19 to force the piston 33 down and hold the pilot valve piston 28 in its left or normal terminal position in which the upper end of the main valve is connected to exhaust through ports 36, 35; the lower end of the cylinder 33 being open to exhaust through ports 20, 18 and 24. As the piston 33 reaches the inner end of its stroke it uncovers the port 321 and the pilot valve 37 is moved to the right, as shown, to allow pressure fluid to flow through ports 361, 15 and force the main valve 11 upwards. The upper end of the cylinder 22 and the outer end of the pilot valve 38 are then connected to exhaust through ports 19 and 23 and fluid is supplied through ports 17 and 18 to act on the larger portion 30<SP>1</SP> of the piston of the pilot valve 37, which is thereby returned to its normal position, and to force the piston 33 upwards until it uncovers the pilot port 32 and the piston of pilot valve 38 is moved to the right so that pressure fluid flows through ports 36 and 16 and forces the main valve to its lower position and the cycle recommences; the pilot valve piston 28 being returned to its normal position by fluid acting on its larger portion 30.

Title: An improved toe for seamless hose and half hose and means for producing the same
IPC: D04B9/46
Filed: 1956-04-28
Abstract: 811,794. Knitting. MORLEY Ltd., I. & R., GILBERT, W., READER, HAND & CO. Ltd., and READER, R. A. July 10, 1957 [April 28, 1956], No. 13082/56. Class 74 (2). To enable the toe of a circularly knitted seamless sock to conform to the shape of the foot one or other of the narrowing pickers is rendered inoperative so that narrowing and widening to form the toe pouch on the usual group of needles only occurs at one end of the group. The needles at the other end are operative for the whole of the formation of the toe and this results in an opening B being formed along the inside edge of the sock which is subsequently linked to close the side of the toe. The inside edge of the toe therefore extends in line with the edge of the foot whilst the. outer edge is shaped in the normal way. The pickers of a circular machine are operated from the pattern drum of the machine and may be rendered inoperative as desired in the production of successive socks in order to produce socks for a right or left foot.

Title: Improvements in junction fittings for coaxial cables
IPC: H01R9/05
Filed: 1938-05-03
Abstract: 495,689. Junction boxes. STANDARD TELEPHONES & CABLES, Ltd. May 3, 1938, No. 13159. Convention date, May 25, 1937. [Class 38 (i)] A junction box for interconnecting coaxial conductors consists of a housing containing a plurality of coupling devices, to which the conductors are connected, each device being provided with safety means operable to connect the inner conductors to the body of the coupling device or to short circuit the inner conductors, and to release a guard which normally prevents access to the inner conductors. The coupling devices 38, 39, are mounted on an insulating plate 60 in a housing 11. The.outer conductors of the coaxial conductors 26, 27, are electrically connected to projections 44 and 45 on the coupling devices 38 and 39 by sleeves 43 respectively. Similarly the conductors 28 and 29 are connected to the coupling devices by slidable sleeves 46 and 47 respectively. Thus the electrical circuit for the outer conductors is through the conductors 26, the coupler 38 and conductors 28 to a repeater (not shown) and then through conductors 29, the coupler 39 and conductor 27. The inner conductors 40 and 41, Figs. 7 and 8, are supported by insulating bushings 48, 49, 50 and 51 within the couplers and are provided with extensions 52, 53 confined in removable metallic caps 54. The extensions are used for testing purposes when the caps are removed. The holes 55 in the couplers allow plungers 56, Fig. 6, to contact with the conductors 40 and 41 and to short circuit them when the button 65 or 66 is pressed. A protective device comprising guard plates 64 and 73, Figs. 4 and 5, joined by side pieces 70 and 71 normally prevents removal of the caps 54 and will not allow the sleeves 46 and 47 to be slid away from the coupler and break the outer conductor circuit. When both buttons 65 and 66 are pressed, however, the device is released and is moved to one side by the spring 74. The caps 54 can then be removed and the sleeves 46 and 47 slid to one side. The latch mechanism 75, Fig. 6, releasing the protective device maintains the plungers 56 in contact with the inner conductors. The binding posts 34 and 35, Fig. 4, on the insulated panels 36 and 37 are for interconnecting the quadded conductors 30, 31, 32 and 33.

Filed: 1960-04-13
Abstract: 946,074. Photo-electric direction finders. CONTINENTAL ELEKTROINDUSTRIE A.G., [trading as CONTINENTAL ELEKTROINDUSTRIE A.G. ASKANIA-WERKE]. April 13, 1960 [April 15, 1959], No. 13251/60. Head. ing H4D. [Also in Division G1] In an optical instrument in which alignment of the line of sight, with reference to at least one co-ordinate, on to a luminous object, and accurate reading of such alignment on a graduated scale, are each effected by a measuring device incorporating photo-electric means, a switch member is provided such that at least part on one device is constituted by part of the other device. The switch may comprise a mirror 11, Fig. 1, which allows light either from the luminous body or from the scale 9 to pass to an image splitting edge 2. This edge divides the beam into two components whose fluxes are different by an amount indicative of the degree of misalignment of the beam and the optical axis. The beams are modulated, for example by a rotating shutter 3, and passed to a photo-cell 5. A generator 7 gives a reference signal of frequency equal to that of the modulation, and this signal is mixed in unit 6 with the output of the photo-cell The resultant signal actuates an indicator 8 which shows the degree of misalignment. The indicator reading is brought to zero in one position of switch 11 by moving the instrument as a whole and in the other position by altering an optical micrometer 12. In a second embodiment, Fig. 2 (not shown), the switch is an electric one. In this case an image splitting edge, a modulating shutter, a reference signal generator, and a photo-cell are required for both the alignment of the instrument and the reading of the scale. The outputs of the photo-cells are successively switched to a single mixing stage and indicator. The invention may be modified to allow alignment with reference to two co-ordinates, and here two scales are required. The individual channels will then be switched to the mixer. An optical and an electrical switch may be used in the same apparatus, and the reference signals need not be of the same frequency.

Title: Improvements in or relating to electrical variable condensers
IPC: H01G5/06
Filed: 1925-05-21
Abstract: 243,618. Lombardi, G. Dec. 10, 1924, [Convention date]. Wireless tuning- apparatus, adjustment devices for. -Condensers of the variable type have one or more stationary plates and a shaft carrying one or more movable plates, an operating knob connected to the shaft, and a second operating knob connected to the shaft by a reducing gear connection including a frictional drive arranged to slip so that the first knob may be used to operate the shaft independently of the second knob. The movable plates are carried on a hollow shaft 19 through which extends a second shaft 21 carrying a pinion 33 which is tapered to provide a bearing for theinner end of the shaft 19. The sleeve 22 is also tapered at 24 to form a bearing for the outer end of the shaft 19 by means of a collar 25 thereon. The shaft 21 projects into a bearing block 26 having a socket 28 in which is a ball thrust bearing 29 held against the shaft by a spring 30 and a plunger 31. Wear at the bearing 24 is thus automatically taken up by the spring 30 and the tapered bearings ensure correct alignment. Pivoted to the plate 11 at 35 is an arm 36 carrying a pin 37 on which is a sleeve 37<1> carrying a gear 38 adapted to mesh with pinion 33. The sleeve also carries a pinion 39 meshing with a gear 40 loose on the shaft 19, the meshing being aided by a spring 39<1>. The gear 40 is located between a nut 42 and washer 41 and a nut 44 and spring plate 43. Rotation of the knob and dial 46, 45 effects direct drive of the shaft 19, the frictional connection between the gearing and shaft 19 slipping so that the latter rotates independently of the gear 40. When the shaft 21 is rotated by the knob 47, fine adjustment of the shaft 19 and movable plates is effected through the reduction gear train, the gear 40 by means of its frictional connection 43 moving the shaft 19 a very small distance.
