Inventor: HALLAM THOMAS BERTRAM
IPC: B07C5/16
Filed: 1957-01-22
Abstract: 853,582. Weighing-apparatus. SPERRY GYROSCOPE CO. Ltd. Oct. 29, 1957 [Jan. 22, 1957], No. 2285/57. Class 143 [Also in Group XXX] In a check weigher the articles to be weighed are fed to a weighing platform 13 by transfer mechanism comprising a vertically movable platform 12 on which the articles are received in turn from a feed channel 11 with which the platform is aligned in its uppermost position, a trigger 35 carried by the platform 12 which when contacted by an article causes the platform to be lowered to a position in alignment with the operating platform, and opposed pusher fingers 14 adapted to move in a horizontal plane midway between the levels of the feed channel and the operating platform for engaging an article on the platform 12 when the latter is lowered and transferring it to the weighing platform. The weighing platform controls means for operating a deflector to determine which of two paths 15, 16 will subsequently be taken by the article. The article is pushed off the weighing platform by a following article being transferred to the weighing platform. The pusher fingers 14 are carried by endless driven chains 43 on either side of the path of the articles, each finger comprising a bell-crank lever 44 pivoted at 45 to the respective chain 43, one end of the lever carrying a roller 47 which is urged into engagement with a track 49 by a spring 48. The track 49 has a dip 51 at a point corresponding with the position at which the fingers engage an article on the lowered platform 12 so that the fingers are swung first backwards and then gradually forwards at this point to engage the article without shock and accelerate it smoothly from the platform 12 to the weighing platform. The lowering mechanism for the platform comprises a rotating cam 26 acting via a follower roller 25 on a pair of parallel pivoted links 22, 23 carried by a support 21. A depending stem 19 of the platform 12 is pivoted at spaced points to the links 22, 23 to form a parallelogram linkage. The platform is normally retained in its upper position by the engagement of a vertical strut 27 pivoted on the support 21 with a notch 29 in an arm 31 extending from the stem 19. When an article engages the trigger lever 35 it acts on the strut 27 through a link 37 but the strut is retained by the notch 29 until the cam 26 is in the position corresponding to the uppermost position of the platform 12 whereupon the notch is just clear of the strut and the article pushing against the trigger pushes the strut away to allow the platform 12 to descend. A link 33 between the stem 19 and the strut and having a slotted connection with the latter prevents the strut re-engaging the notch until the platform 12 has returned to its upper position after removal of the article by the pusher fingers 14. Specification 853,583 is referred to.

Filed: 1936-01-24
Abstract: 469,121. Methods of generating steam. NIXON, I. G. Jan. 24, 1936, No. 2344. [Class 123 (ii)] In generating purified steam from saline waters, feedwater is passed through continuous coils 5, 8 in a firebox 1, the heat supplied being so controlled that the steam generated is in equilibrium at the pressure prevailing at the outlet 10 with a concentrated but not saturated solution, the foul steam being passed through a de-salineator 16 in which it is washed by a counter-current of water supplied by a pump 25a. The purified steam may be superheated in furnace coils 11. A throttle valve at the generator coil outlet may maintain a slightly less concentrated solution at an excess pressure in the coil in order to avoid deposit in the coil. Liquid passing the throttle flashes to steam and a slightly more concentrated solution. The de-salineator has bubble trays and caps, or packings, e.g. Raschig rings, clay shapes, dephlegmator pans, or distribution baffles. In a modification the steam is washed by reflux condensed on a bank of feedwater tubes at the top of the de-salineator. Pressure in the de-salineator is caused to control the feedwater pump speed and a temperature control instrument of potentiometer type is preferably employed at the generator coil outlet.

Jan. 23, 1931, No. 2345. Convention date, Jan. 24, 1930. Void [Published under Sect. 91 of the Acts]. [Class 35.] Armatures, cooling; casings.- In an induction motor, more particularly for driving heavy rotating masses such as rolling mills which have to be started or reversed frequently, part of the rotor winding projects outside the casing and the winding is designed so that the greater part of the heat generated therein is produced in the projecting part. As shown applied to a squirrel cage motor, one end is completely enclosed but the casing at the other end comprises a fixed wall a and a wall b secured to the rotor with a narrow gap between the walls. The bars c of the rotor winding extend through the wall b and are electrically connected together by lugs d formed on a ring, the material and cross section of the lugs being such that the greater portion of the heat is generated therein. The lugs may be constructed to dissipate as much heat as possible and to act as fan blades or a current of air may be directed on those parts of the winding from a separate fan on the machine or from an external source. A mului-squirrel cage or a phase winding may be employed in the rotor. The resistance of the rotor winding is such that the torque is a maximum at standstill or at a speed far below synchronism.

Abstract: 719,148. Bridges. ENGINEERING & INDUSTRIAL EXPORTS, Ltd. April 29, 1953 [Jan. 29, 1952], No. 2392/52. Class 20 (1) A method of increasing the load-bearing capacity of a bridge built of standard units 1 forming a braced girder structure, including upper and lower articulated chord members 13, 3, comprises providing tension members 2, e.g. rods of high tensile steel, which are arranged and pretensioned to pre-stress at least the main members of the bridge opposite to the stresses therein due to the dead-load. The rods 2 are in lengths corresponding to the units 1, adjacent lengths being connected by coupling blocks 5, 6 and pins. the rods 2 extending the length of the bridge below the members 3. Hydraulic jacks may be used to tension the rods 2, the threaded ends of which are subsequently secured by nuts 12 against the inclined faces 9 of anchorages 8. Depending struts 4, readily attachable to the bridge at 15, have holes 14 in which the blocks 5 are slidably engaged, the holes 14 being vertically spaced to permit variation in the angular disposition of the rods 2. The effect of the pretensioned rods 2 is to pre-compress the member 3 and pre-tension the member 13, thus counteracting the stresses set up in these members by the natural sag of the bridge. In a modification in which the bridge has intermediate supports, the tension members extend beneath the bridge as before except at the supports, where they are above the bridge.

Title: Improvements in timing devices
Inventor: KENDON SIDNEY PETER
IPC: G03D13/00
Filed: 1954-01-27
Abstract: 773,498. Time-alarm signals; electric measuring systems. VENNER, Ltd. April 27, 1955 [Jan. 27, 1954], No. 2541/54. Classes 40 (1) and 118 (2). [Also in Group XX] A timing device of the kind arranged to cause a desired operation (e.g. an alarm) to be effected after the lapse of a period of time commencing with the instant at which the device is rendered operative is arranged so that the period of time is varied automatically in accordance with changes in the value of some other variable quantity. An embodiment is described as applied to photographic development where a period of time must be varied in accordance with the temperature of the developing bath. The basic timer comprises a synchronous motor 3 driving a shaft 1 via a friction clutch 2 to move a pointer 25 over a time-scale 26. Contacts 6 and 7, co-operating with cams 4 and 5 on shaft 1, are carried on a disc 9, through which the shaft 1 passes freely and to which is attached scale 26 by means of rods 27 and 28. The device is set by pushing button 20 to rotate the shaft 1 until an arm 21 engages a stop 22 adjustable from outside the case (not shown) by worm 24. The motor 3 then drives the shaft 1 back until at zero indication of the pointer 25 the cam 5 allows contacts 7 to close and energize a buzzer 16, and a little later (e.g. one minute) cam 4 opens contacts 6 to disconnect the supply from both buzzer 16 and motor 3. The start-position of shaft 1 is thus determined by the adjustable stop 22 and the end-position by disc 9 which is also adjustable by means of gearing 66. The time interval therefore depends upon both these adjustments and the pointer 25 always indicates on scale 26 the nett time interval. The setting of disc 9 is made by servomotors 53, 54 driving a bevel gear 59 via clutches 57 and 60 respectively. Servomotors 53, 54 are arranged to drive the gear 59 in opposite directions and are controlled by contacts of a moving-coil relay 38 connected between the sliders of two potentiometers 32, 39 forming a bridge network. Potentiometer 32 is varied by a temperature-sensitive bellows 29 mounted on a developing tank, and the potentiometer 39 is caused to follow-up by having its slider 44 driven from the train of gears between servomotors 53, 54 and disc 9. The balanceposition of slider 44 will be in accordance with the temperature of developer and a pointer 64 may be provided to indicate the temperature on a scale 65. The winding of potentiometer 39 is graded to produce the desired relationship between temperature and movement of disc 9.

Suitable friction insert materials may include iron, bronze and aluminium oxide. The friction inserts may be continuous or discontinuous and of various shapes with oil channel gaps between. The inner and outer members may be of steel, cast iron or cast steel. As shown, the outer member comprises parts 1, 2 screwed together and journalled directly on the shaft 10, on cylindrical extensions of the transmission casing, or, as shown, by bearings 4, 5, 24, 25 on the inner members 8, 9. Constant disengaging pressure is supplied to chambers 17, 18 through passages 12-16, inevitable leakage being centrifuged through drains 30 from oil traps 28 and through peripheral drains 26, 27. Engaging pressure is supplied to the chamber 23 through passages 19, 20, 22. The friction material pads 31, 32 are located in recesses to free securing bolts 33 from shearing stress. Whilst the pads 31, 32 are shown in line they may be staggered. The oil pressure may be so adjusted as to provide a torque-limiting clutch slipping on overload.
