Patent GB-789680-A (GB)
Title: Improvements in and relating to shaft sealing arrangements
Inventor: BOWDEN ANDREW THOMPSON
IPC: F04D29/14
Filed: 1955-04-21
Abstract: 789,680. Stuffing-box substitutes. PARSONS & CO., Ltd., C. A. April 12, 1956 [April 21, 1955], No. 11513/55. Class 122 (5). A shaft sealing arrangement comprises a sealing means 10, 11 which prevents leakage of fluid along the rotating shaft 4 where it passes through the wall 6 of an enclosure containing the fluid, a supplementary seal 12 for preventing the escape of fluid from the housing 6 when the shaft is stationary and the seals 10 and 11 are not functioning, and means 14 for moving the shaft axially to bring an O-ring 28 on a collar 13 into sealing contact with the wall 6 to form the supplementary seal 12. As shown, the shaft 4 of the blower 1 is driven by a prime mover 6a and enclosed in a housing 7. The seal 10 is of labyrinth type and the seal 11 is of the liquid-film thrust-collar type, comprising a sealing ring 15 which is maintained in contact with the face of a collar 18 by springs 17. An annular groove 19 in the sealing face 16 of the ring is fed with oil under pressure from a reservoir 20 via holes 21, 22 to the face 16. Radial grooves extending outwardly from the groove 19 carry most of the oil from the sealing face 16 but a small amount flows inwardly over an ungrooved inner portion of the face to a clearance 24 around the shaft and thence to a collecting space 25 for separation from the working fluid. U-shaped sealing rings 26 prevent the leakage of oil from the annular space 27 between the ring 15 and housing 7. Maintenance access to the latter rings 26 or to the sealing face 16 may be achieved without reducing pressure or evacuating the enclosed blower system, by moving the shaft, when stationary, axially by the means 14, to close the seal 12, so that the upper part of the housing 7 may be removed for the withdrawal of the shaft bearings 8 and 9. The collar 18 can also then be moved along the shaft and the U-rings 26 withdrawn and cut away; new rings housed in a container 31 are then moved into place along the shaft. The seal 11 may be replaced after withdrawing the bearing 9 while the shaft is supported by a strap placed immediately to the right of the bearing. After replacing the seals, the shaft is moved back to its original position by the means 14 which, if the pressure in the enclosed system is high, may be augmented by the introduction of a pressurized fluid into the space 5 between the labyrinth seal 10 and the collar 13.

Abstract: 723,355. Towelling dispensers. AMERICAN LINEN SUPPLY CO. May 13, 1952, No. 12085/52. Class 18. The support 21 for a roll of towelling is pivotally mounted between side plates 2, 3 of a dispenser in order that the support may be swung outwardly of the plates when the cover 5 is removed to facilitate access to and reloading of the dispenser. In operation with the support 21 in its inner position and the cover closed, towelling is withdrawn through a slot between the front edge of the cover and the upturned edge 7 of a bottom plate 4. As the towelling is withdrawn, it passes over a feed roller 9 into contact with which it is pressed by a pressure roller 14 and is guided to the slot by an apron 17 attached to the roller 14. A pawl and ratchet is associated with the roller 9 to prevent reverse movement of the roller. Attached to the roller 9 is a stop member 40 which engages a corresponding member 41 after a length of towelling has been withdrawn to prevent further withdrawal. This member 41 is associated with a time delay mechanism 45, 46 which delays disengagement of the members 40, 41 and causes a delay between each successive withdrawal. A hand wheel 12 is also attached to the roller 9 and is adapted to be operated after a length of towelling has been severed on the lower edge of the cover to advance the towelling sufficiently to enable its end to be grasped. Alternatively, a spring is so attached to the wheel 12 that after the time delay mechanism has released the members 40, 41, the wheel is turned by the pull of the spring to advance the towelling. A combined brake and indicator 30 is spring pressed against the supply roll to prevent undue rotation and at the same time registers against a scale through a slot in the cover to indicate the amount of towelling remaining on the roll.

Title: Improvements in starting means for mercury vapour rectifiers and like apparatus
IPC: H01J13/48
Filed: 1927-05-06
Abstract: 280,438. General Electric Co., Ltd., and Weintraub, E. May 6, 1927. Low - pressure metallic - vapour apparatus.- In mercury vapour rectifiers or like apparatus having one or more side tubes F each containing one or more electrodes H and having a starting electrode C dipping into the mercury cathode B when the rectifier is inoperative and separated from the cathode B to initiate a starting arc, this separation is effected by the thermal expansion of a member D placed in the path, in one of the tubes F, of an arc other than a starting arc. The member D may be a bimetallic strip heated by the starting current or otherwise to separate the electrodes B, C initially in known manner. The electrode H is a principal or sustaining anode and lies directly in the tube F or in a bulb G. The strip D is heated, to maintain the electrode C permanently out of contact with the cathode B during operation of the rectifier, directly by the arc from the anode H and also by radiation from the anode and, if the electrode C is also a sustaining anode, additionally by the sustaining current.

IPC: G09C1/04
Filed: 1922-05-01
Abstract: 180,653. Scherbius, A. May 23, 1921, [Convention date]. Electric machines for coding and decoding.-Relates to ciphering and deciphering apparatus for translating two-figure combinations into characters, one of which is a vowel and the other a consonant, and in which the vowels are arranged to correspond to two groups of figures, and the consonants to a set of figures, so that when one consonant is used the vowel is represented by one figure, and when another is used the same vowel is represented by a different figure. Two rows of electrical contacts VII, VIII are provided for the figures and two series of indicators I, II for the characters. The row of contacts VII is divided into two groups, every pair of contacts, one for each group, being connected to a common character indicator in the series I. Each contact of the row VIII is electrically connected with two character indicators in row II, which are combined into one group electrically connected to the rows of divided contacts in row VII. An electrical contact is arranged in parallel with each indicator, one side of each contact and one side of each indicator being connected to the group lines so that change-over for decipering can be effected, figure indicators and character contacts being then joined up. The change-over is made by mechanically coupled switches 17, 18, 19. Multiple switches 11, 12 may be employed to vary the fortuitous electrical connections through the apparatus. On making a figure contact in each of the rows VII, VIII, character indicators in rows I, II are actuated when enciphering, and for each pair of contacts made, separate electric circuits are completed either by way of the top or bottom of the switch 19. The contacts are coupled mechanically so that subsequent depressions of the key member release the previously depressed keys, thereby breaking one circuit before the next is made. Instead of lamp indicators, type-wheel or type-lever mechanism can be employed to give a printed record. In a type-wheel arrangement half of the indicators in row II are arranged on the periphery of one typewheel and the other half on another type-wheel, exciting electromagnets located in the group lines arbitrarily selecting either type-wheel.
