Title: Improvements in or relating to rotary pipe joints
IPC: F16L27/08
Filed: 1957-05-17
Abstract: 838,940. Pipe joints. JACOBSON, F. May 17, 1957, No. 15841/57. Class 99(1). [Also in Group XXIX] A rotary pipe joint comprises a tubular housing 10 within which a hollow shaft end 33 rotates and a header of bronze &c., screwthreaded to the housing and having an elastic element in the form of a bellows permanently attached made of spring brass, monel metal &c., which is spaced from the housing and compresses sealing means on to the shaft end. The sealing means includes a support member 25 to which the bellows is welded with tapering side walls to receive spaced from a transverse wall 31 a seal ring 40 of graphite or graphite impregnated metal with a wearing face 42 in contact with the shaft end, the amount of compression being externally adjustable by screwed insertion of the header 13, the depth of adjustment locked by a set screw, Fig. 2 (not shown). The shaft end 33 is of steel and has a hardened, enlarged head 34 carried in the housing 10 by an antifriction bearing 36 locked in the housing by a ring 37, the inner surface of which engages a collar 38 on the shaft to minimize lateral movement. The portion of member 25 unfilled from the seal ring to the transverse wall 31 constitutes a pressure equalizing chamber M dimensioned so that the hydraulic pressure within is smaller than the sum of the hydraulic pressure in and the compressive pressure of the bellows, and the longitudinal thickness of the seal ring 40 provides constant wear both on the face 42 and at the other tapered end to maintain the chamber M. An additional recess 42a in the seal ring provides a pressure reducing chamber dimensioned to reduce to a minimum wear on faces 42 and 35. If internal pressure is excessive, the bellows acts as a safety valve and is thereby lifted, leakage taking place and venting to atmosphere through a space 37a. Fig. 1 shows a joint for a syphon system the flow taking place from an inlet 18, through bore 23, bellows and seal ring to bore 33a of shaft end 33, condensate returning through a syphon tube 45 to elbow 46 which may be replaced by a closure cap if no return is required. In a modification, Fig. 3, the end of bellows 48, support member 49 and seal ring 50 are positioned within the enlarged head 51 of a shaft 52 to reduce wobbling of wearing surface 55 in event of shaft misalignment. Leakage may be vented through space 52a.

Abstract: 975,488. Ski bindings. H. MARKER. April 23, 1963 [April 30, 1962], No. 16013/63. Heading A6D. A safety release device for ski bindings comprises a plate 2 bolted to the ski 1 and a twopart housing 5, 6 pivotally mounted on the plate 2 by meansof pin 4 but normally restrained from moving relative to the plate by ball detents 11 engaging recesses 13 in the plate. The detents are urged into engagement with the recesses 13 by a block 9 of elastic material located within the housing, a nut 8 being provided for adjusting the pressure exerted by the block on the detents. The device also comprises a member 15 for engagement with the skier's boot, the member being fast with a pin 14 rotatably mounted in the housing 5, 6, and having an extension 18 normally abutting one face of the block 9. In the event of an excessive torque being applied to the skier's boot or leg, the detents 11 are urged out of engagement with their respective recesses, and the housing 5, 6 together with the member 15 rotates about the pin 4. Movement of the member 15, however, is restricted by its contact with the skier's boot, with the result that the pin 14 and member 15 pivot relative to the housing and block 9 to an extent which is limited by the abutment of a part 16 of member 15 against the housing 5, 6. In this position, one edge of extension 18 elastically deforms block 9, so that on removing the boot from the binding, the resilience of the block returns the fastening to its central position. In a modification, the member 15 comprises three parts, two for abutting the side edges of the skier's boot and one for abutting the toe cap, all three parts being mounted on the pin 14 and being provided with extensions for abutting the block 9.

Two control conductors 7, 8, extend from the point of control C throughout the whole of the district and at each signalling device 1 the energizing windings of the relays A, B, are connected to the conductors 7, 8 through a change-over switch 9. The control conductors 7, 8 are arranged to be alternately connected to the positive supply conductor 5 by means of rotating drum switches 27, 28 operated by a clock actuated mechanism 29, a manually controlled switch 30 being provided so that both conductors 7 and 8 can be simultaneously de-energized. The contacts of the A and B relays are so arranged that when the A relay is energized and the B relay is deenergized as shown in Fig. 2 the element 2 only of the signalling device 1 is supplied with current, whilst when the A relay is de-energized and the B relay is energized the signal element 3 only is supplied with current, and when both the relays A and B are de-energized the caution signal element 4 only is supplied with current. By reversing the position of the switch 9 at any signalling device 1 the conditions of operation will be reversed for the particular device. The switch 9 at any signalling device 1 may also be set into an intermediate or " off " position so that both the relays A and B are de-energized and the caution signal is given continuously by the signal Element 4 thus permitting of non- automatic control of traffic at this point. If it is desired to give a general caution signal throughout the district the switch 30 can be opened. A modified signalling system is described by means of which a special danger signal such as a bell can be made operative at each signalling device throughout the district by means of a switch at the point of control.

Title: A method of detecting and correcting tensile and compressional stresses arising in the rolled stock between consecutive roll stands of a line in a continuous rolling mill, and apparatus for performing the same
IPC: B21B37/52
Filed: 1963-04-24
Abstract: 1,031,037. Rolling. SCHLOEMANN A.G. April 24, 1963 [May 11, 1962], No. 16114/63. Heading B3M. A method of detecting and correcting tensile or compressive stresses is rolled material between the stands of a continuous mill includes measuring the speed of the material continuously or intermittently after the final stand of the mill and altering the screwdown or speeds of the individual stands in order to eliminate such stresses in a subsequent length of material. The speed of a strip 5 after passing stands 1-4 is measured by a roller 7, the roller driving a tachometer dynamo 8 whose output is measured by an instrument 9. Alternatively the roller may be connected to a pulse generator and associated counters. Speed measurement using the roller 7 as the trailing end of the strip leaves stand 1, for example, indicates whether tension or compression existed between stands 1 and 2. If the stands 1-4 have a common drive the appropriate screwdowns are altered, but if the stands are individually driven the stand speeds can also be adjusted.

Title: A machine for adjusting, testing, and stacking electrical valve sockets
IPC: H01J9/46
Filed: 1959-05-11
Abstract: 881,162. Turret machines for assembling electron valve bases. SYLVANIA ELECTRIC PRODUCTS Inc. May 11, 1959 [May 9, 1958], No. 16131/59. Class 39(2) [Also in Group XVII] The invention relates to a machine in which sockets for electron valves are fed from a socket assembly turret into a device that adjusts or flares the pins extending from the socket, then tests the socket to determine the presence of the correct number of pins, and then transfers the accepted sockets on to backing strips where they are grouped together in a pre-arranged order. The completed sockets 27, Fig. 10, housed in an intermittently rotating turret 24 are ejected from the turret by a plunger 38 into a pair of gripping arms 40. The arms 40, pivoted at 74, swing the sockets into alignment with a recess 100 in a vertical turret member 98, the sockets being forced into the recess 100 by a reciprocating bar 122 which, on moving to the right, draws a stripper finger 132 under a cam surface 136 such that the finger 132 rotates anti-clockwise to push the socket from the arms 40 into the recess 100. The finger 132 and the arms 40 then revert to their original position and the vertical turret 98 rotates through 60 degrees to a position where a pin adjusting or flaring tool 158 moves axially towards the socket to deflect the pins to the required amount. The turret 98 then rotates to a further position where a pin detecting device 162 is reciprocated against the pins of the socket. If a pin is missing an electrically operated solenoid 178 operates a plunger 192 to eject the faulty socket from the turret 98. The turret 98 then rotates the socket to a further position where a plunger 194 pushes accepted sockets on to a longitudinal strip 198. The sockets 27, Fig. 5, are grooved at 31 such that they slide on to and are held by the packaging strip 198. When the strip is full the leading socket contacts a switch which causes hydraulic means to index the strip 198 away from the plunger 19 and present a new strip to this loading position. The strips 198 are each mounted in a channel 206, there being a plurality of these channels mounted on a common axle 204, Fig. 4, by means of discs 202. The stacking strips 198 are held in the channels 206 by means of arms 210, Fig. 4, pivoted at 212. As the discs 202 rotate the arms 210 eventually contact a cam surface 218 causing the arms to pivot about their points 212 and so release the filled stacking strip from the channel 206. Empty channels 206 are filled manually with fresh stacking strips 198. The channels 206 are rotated intermittently about their common axis 204 and means is included to stop the flow of socket members from the turret 24 to the turret 98 whilst there is no channel 206 aligned with the ejecting pin 194.
