Title: Improvements in or relating to joints and terminal connections for high voltage electric cables
IPC: H02G15/103
Filed: 1929-09-12
Abstract: 339,654. Reyrolle & Co., Ltd., A., Mirrey, J., and Christie, J. Sept. 12, 1929. Cable joints and terminals. - A joint or terminal connection for an oilfilled sheathed high tension cable, particularly for use in lead-in connections to switchgear, transformers, or other electrical apparatus, comprises a length of in. sulated cable between the joint and the sheath, which is stripped back so far as to prevent flash over, the insulated cable length being surrounded by a condenser type insulator having the conducting layers arranged in two groups in series. The innermost conducting layer at the insulator end adjacent the sheath is electrically connected to the sheath, and the innermost conducting layer at the other end of the insulator is electrically connected to the conductor. In the construction of Fig. 1 a sealing bell joint for use with apparatus out of doors, comprises a high tension conductor A with bared insulation B and lead sheath C which is earthed and connected, preferably by a wiped joint, to a metal gland D. A tubular condenser type insulator E surrounds the bared insulation B, and preferably consists of built-up layers of impregnated paper with embedded conducting foil E'. The layers of foil E' are arranged in two groups, the innermost layers of the groups being electrically connected to the bared end of the conductor A, and the sheath C, respectively. The layers in each group are stepped, and the outermost layer is common to the two groups. The lower end of the insulator E, which is surrounded bv a shedded insulator G mounted with, preferably, oil-tight joints, between the gland D and a cap H, is held in a ring F which may form part of the gland D. In a modified construction of lead-in for indoor use in which the insulator G is omitted, the insulator E forms the external covering of the point and fits, with oil-tight joints, into rings attached to the gland and cap respectively. In a further modification in which the insulator G is omitted, thejoint is contained in an oil-tight metal casing which may form part of, or be attached to, the casing of oil-filled switchgear. Fig. 4 shows a joint between two high tension cables. Two condenser insulators E fit within an insulating tube M, and the whole joint is contained in a metal casing L<1> which is joined to glands D and intended to contain oil. The conductors A of the cables are joined by a sleeve and by braid or sliding connections. Connections J<1> join the inner most layers of the insulators E to the conductors, and connections N join the innermost layers of the insulators E to the glands D. In the construction of Fig. 5, the two condenser insulators of Fig. 4 are replaced by one long condenser insulator E<2> with four groups of stepped conducting layers, two sets for each cable. The inner layers adjacent to the conductor ends have a common innermost layer E<3>. A metal sleeve 0, within the insulator E<2>, has an electrical connection J<2> to the conductors A.

Title: Improvements in hydraulic servomotor control means to control the reversal and vary the capacity of variable capacity pumps for use with hydraulic presses
Inventor: BERG FRITZ
IPC: F04B49/12
Filed: 1957-09-06
Abstract: 873,579. Fluid-pressure servomotor-control systems. DREMASCHINENWERK LEIPZIG VEB. Sept. 6, 1957, No. 28145/57. Class 135. Apparatus controlling the operation of hydraulic presses comprises a variable capacity pump 2 including a member 1 displaceable to vary the pump capacity by an hydraulic servomotor piston 4 operable by a piston valve 6 under the control of pump delivery pressure and a further hydraulic servomotor piston 14 whose piston valve 13 is positioned by a synchromotor 10 in response to the hand positioning of a remotely disposed synchro-generator 9. The setting of the generator 9 determines the position of the servomotor piston 14 which through a rack 16 and a toothed quadrant positions a lever 17. The lever 17 engages a collar 18 fixed on the spindle 6b of the piston valve 6, and against the loading of a spring 19 transmitted to the piston valve through a pivoted lever 21, positions the piston valve 6 and the servomotor piston 4 to predetermine the eccentricity e1 of the displaceable member 1 and hence the pump delivery and the speed of the working stroke of the press. When the press approaches the end of its working stroke pressure in the ram cylinder builds up and this pressure is transmitted through pump delivery line 25 and a line 26 to act on a differential piston 23 against the spring 19, which through the lever 21 moves the piston valve 6 and the servomotor piston 4 to reduce the eccentricity of the member 1 and hence pump delivery. When the press reaches the end of its stroke, a reversing valve 27 may be operated either manually or electrically to direct pressure liquid from a pump supplying the servomotors on to a piston 20, whence the piston valve 6 is moved to its extreme leftward position and through the servomotor piston 4 the member 1 is displaced its maximum amount of eccentricity e2 in the opposite direction limited by a stop 6a on the spindle 6b to reverse the pump and cause a rapid reversal stroke of the press. The loading of the spring 19 may be adjusted by an electric motor in circuit with a differential relay and controlling and receiving potentiometers. A further synchro-generator may be included in circuit with the synchro-generator 9 and the synchro-motor 10, the synchrogenerator 9 being set to give a high approach speed of the press and the further synchrogenerator an independent pre-set operational speed thereof.

Title: Surgical table
IPC: A61G13/04
Filed: 1961-08-03
Abstract: 990,737. Surgical tables. RITTER CO. Inc. Aug. 3, 1961 [Sept. 19, 1960], No. 28259/61. Heading A4H. [Also in Division F1] In a hydraulically operated surgical table, all control valves are arranged on a single manual 34 which is carried on an arm 102 rotatable to either side of the head end of the table. The sliding spool type valves, such as 53, are connected through flexible plastic tubing 133, 137 to the remainder of a conventional hydraulic system (Fig. 22, not shown) including pump and electric motor unit 79, sump 69 and five double-acting hydraulic rams, such as 51. The system also includes overload relief valves and locking valves (Fig 12, not shown) for each ram. Before ram 51 can be actuated by lever 36, plate 149 must be held down to compress bellows 152 and thus close bellows-operated motor switch 157. The rams 48, 49 and 51 (Fig. 15) control the height and angular position of the pelvic section 42 which supports all the rest of the table top. Rams 46 and 47 (Fig. 2) mounted on the underside of the pelvic section adjust the inclination of the spinal and femoral sections, respectively, relatively thereto. The pelvic section 42 is carried on pillar 186 and rams 49, 51 extending together with stabilizing pillar 187 from vertically movable platform 179. Universal joints at both ends of the rams 49 and 51 and at the top of pillar 186 enable section 42 to be tilted about longitudinal and transverse axes. Platforms 176 and 182 are locked together on sleeves 180 which slide on vertical pillars 183 secured to the base 163. Platform 179 is slidably mounted on sleeves 180. Platforms 176 and 182 move with ram piston rood 174. Their motion is transmitted to platform 179 by pulleys carried by platform 176 and 182 and steel tape 196 anchored to platform 179 at 197 and to the stationary cylinder of ram 48. The vertical displacement of platform 179 is thus thrice that of platforms 176, 182, thus allowing the amplitude of the movement of piston rod 174 to be kept small. Specifications 990,736, 990,738 and 990,739 are referred to.
