Title: Improvements in or relating to card sets for use with spinning plants
IPC: D01G15/64
Filed: 1955-01-26
Abstract: 793,611. Carding fibres and spinning yarns. CECCHI, B. Jan. 26, 1955 [April 17, 1954; Sept. 7, 1954], No. 2332/55. Drawings to Specification. Classes 120(1) and 120(3) In a card set for the direct supply of slubbings or equivalent form of fibrous material to a spinning plant, the machine which produces the slubbing &c., has two or more units in respect of the machines which feed (carded) material thereto and is operated at reduced speed to enable the slubbings &c. to be fed directly to a continuous and/or discontinuous spinning plant e.g. if three such units feed slubbing to separate spinning means, then any two units can absorb the output of carded material fed thereto and the remaining unit may be stopped so that spinning spindles associated therewith may be changed, Fig. 4 (not shown). The carding member(s), doffer and associated elements of a finisher card and/or the web-dividing apparatus and rubbing leathers may be located at a higher level than the spinning plant and with the. two latter apparatus of the card directly thereover, Figs. 2, 3, 5 and 6 (not shown): fibrous material from preceding machine in the card set or carded web from the doffer is raised to the required height by inclined conveyer belts. The spinning frames may be fixed or mounted to slide vertically or horizontally on tracks or rails according to the flexibility of operation of the particular plant provided by the associated card set. If discontinuous spinning plant is used, slubbings are conveyed thereto via recovery means which can be alternately displaced in the vertical direction synchronously with the horizontal movement of the machine carriage in order to accommodate lengths of slubbing and feed them into the spinning machine during the run-out stroke of the carriage. Specification 793,612 is referred to.

Title: Improvements in or relating to echo sounding apparatus
IPC: G01S15/14
Filed: 1936-01-24
Abstract: 469,417. Echo-sounding and distancemeasuring apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and MYERS, L. M. Jan. 24, 1936, No. 2352. [Class 118 (ii)] The time interval in an echo-sounding apparatus is measured by the charge built up on a condenser, the condenser commencing to charge when the impulse is transmitted and being discharged when the reply signal is received. The charge-measuring instrument is shunted by a large condenser so that a continuous record of depth is given. When a pulse is transmitted a corresponding pulse is passed by winding 15 to the control triode 10, so that the grid glow discharge device 4 of the type known under the Registered Trade Mark " Thyratron " is triggered and condenser 6 begins to charge. The echo signal is passed through band-pass filter 17 to control triode 10, which now causes the " Thyratron " 4 to be extinguished, and to " Thyratron " 20 which triggers and discharges condenser 6. The charge built up on the condenser 6 is passed by amplifying valve 27 to electrostatic voltmeter 30. The condenser 31 is large enough for the leakage to be slow and acts as a smoothing condenser so that the needle of the voltmeter continuously indicates depth. The circuit parameters are made adjustable to enable the apparatus to be used over a large range of depths.

Title: Improvements in variable speed epicyclic gearing
IPC: F16H3/54
Filed: 1925-01-27
Abstract: 251,030. Rendell, E. D. Jan. 27, 1925. Variable-speed epicyclic gearing comprises a simple spur train C, D, F adapted to yield a solid high-speed drive and two reductions. The planet gears D are carried by a driven sleeve B which rotates on a non-rotary shaft A spigoted into the aligned driving-shaft P. Operation is effected by two sliding systems, one of which comprises a clutch member I sliding on the squared end of the shaft P and having a circular groove engaged by radial pins K which register with holes in a non-rotary dog stopping-member M. The other system comprises a simple dog member T sliding on a squared part S of the shaft A The configuration shown yields the low speed, the sun gear C being driven by inner dogs J upon the member I, and the internallytoothed ring F being held fast by the dog member T. For the solid drive, the member T is disengaged and the gear C and ring F are driven simultaneously by the two sets of dogs J. The pins K are adapted to be traversed by telescoping links L connecting to a control shaft Z, which also carries a cam plate X, which, through a linkage W, V. R., operates also the member T. In a modification, the dual control is effected by an annular cam encircling the gearing. In a further modification, driving and driven members are arranged on the same side of the gearing by making the non-rotary shaft corresponding to A, hollow, and passing the driving-shaft therethrough. Specifications 12873/09 and 7991/13 are referred to.
Patent GB-411070-A (GB)
Title: Improvements in or relating to direction indicators for vehicles
IPC: B60Q1/34
Filed: 1934-01-23
Abstract: 411,070. Road-traffic signals on vehicles. GORLER, E., 53, Muhlenstrasse, and FUCHS, H., 32, Christinenstrasse, both in Berlin. Jan. 23, 1934, No. 2400. [Class 118 (ii).] A direction indicator of the semaphore type is moved into its operative position and back to normal by the same spring, the point of application of the spring to the arm being moved from one to the other side of the axis of the arm to enable the two operations to be performed. A plate 9, with an arcuate slot 10, is rigidly connected to the arm 3. A pin 13 connected to a plate 12 pivoted at 11 carries the end of spring 14 and moves in the slot 10. If the arm is in the position of rest shown in Fig. 1 and the arm 19 is moved through 90‹ in the direction indicated by the arrow (Fig. 5) the plate 25 is rotated from the position shown in Fig. 5 to that shown in Fig. 4 and pin 28, which is on plate 12, carries plate 12 so that 13 moves to the right hand side of pivot 4 and the arm is swung up by the spring into the position shown in Fig. 2. The handle 19 is spring returned to its initial position, the end 18 being sprung to allow it to ride over one of the teeth 17. If now the handle 19 is again operated, 25 moves through a further quarter revolution back to the position shown in Fig. 5, the projection 26 first releasing 27 and then acting on 30 so that the edge 31 forces 28 back. The pin 13 is thus moved to the left of pivot 4 and the spring 14 pulls the arm into its normal position. When the arm is in signalling position, pin 28 coincides with the pin 4 so that the arm swings up and down under the oscillating movement of spring 14. A lamp 5 carried by the arm is-illuminated when the arm is in its operative position, the lamp being fed through spring 6 which rests on insulated contact 7 when the arm is normal.

Filed: 1939-01-24
Abstract: 524.212. Drum controllers. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 24, 1939, No. 2447. Convention date, Jan. 24, 1938. [Class 38 (iii)] Sequential contactors 1, 2 have pawl and ratchet connections 4, 5 and 7, 8 with a shaft 11, driving through a spring 18 a control drum 19. so that when one contactor is energized, e.g., by closure of a switch 23, the drum is moved to a position in which the next contactor 2 receives energization from a contact 22 on the drum. In this way, closure of the switch 23 causes sequential closing of a series of contactors. The drum is retarded by a gear driven air vane 26. A spring 12 returns the driver and ratchet shaft to the zero position when the system is deenergized. By providing suitable segments on the drum 19 and a number of notches in the ratchets 5, 8 a number of successive switching operations can be effected with only two contactors, other contactors being operated either electromagnetically from the drum, or by cams.

Abstract: 964,364. Rotary piston engines. DAIMLERBENZ A.G. Jan. 23, 1962 [Jan. 27, 1961], No. 2481/62. Heading F1F. A rotary I.C. engine of the n and n+1 lobe type having a substantially triangular piston 3, Fig. 1 mounted in a two-lobed housing 1 with its axis eccentric and parallel to the engine shaft axis, has the substantially equidistant inner boundary 2 of the housing from the contour envelope 8 of the piston, just beyond a zone nearest to the axis brought closer to the contour envelope. In one embodiment, the inner boundary 2 shown chain-dotted in Fig. 3, is turned forwards through an angle a (0À5 to 1 degree) to take up the full line position 2<SP>1</SP>. At the zone nearest the axis the outwardlyurging forces on the sealing strips 9 are at their minimum. The movement of the boundary nearer to the contour envelope is said to ensure better sealing and alleviates chatter and wear as the outwardly urging forces increase. In another embodiment, the profile of the inner boundary is altered in the region of the said zone to reduce the distance between it and the contour envelope.

Title: Catheters and like drainage tubes and the manufacture thereof
IPC: A61M25/00
Filed: 1953-01-29
Abstract: 749,753. Catheters. MANSELL, E. A., and FRANKLIN & SONS, Ltd., J. G. Jan. 26, 1954 [Jan. 29, 1953], No. 2643/53. Class 81(2). [Also in Group V] A catheter body has its tube wall and integral end wall produced by dipping and has a preformed solid end plug incorporated in and secured within its distal end wall. The catheter C is made of latex or an organosol and is provided with a plug the inner end of which is hollow and merges with the wall of an eyelet D. The distal end of the catheter is cylindrical, bulbous or olivary. The catheter is made by dipping a former A elongated by the plug B, which is made of uncured or semicured rubber or plastic, into a tank containing latex (which may contain prevulcanising agents) or an organosol e.g. polyvinyl chloride powder in liquid plasticizer. After a sufficient coating has formed on the former A it is removed from the tank and the former A is withdrawn leaving the plug B in the distal end of the catheter c. Additional coatings may be applied in the same way. After drying, the catheter is vulcanised if necessary and eyelets D are cut in the required position. When latex is used, coagulants such as a 50 per cent solution of calcium nitrate in water or alcohol may be added or the latex may be gelled by the application of heat. Alternatively the former together with the plug may be introduced into a tube having an internal shape the same as the external shape of the finished catheter and containing or supplied with latex or an organosol. After gelling, the former and the coating are withdrawn and the catheter finished as in the first-described method. The catheter may alternatively be formed with a hollow distal end into which a plug is introduced through the eyelet. The former may be so shaped that the catheter is given a flared proximal end. Specifications 193,451, 248,608 and 330,520, [all in Class 70], are referred to.

Title: Infinitely variable cone pulley gear
IPC: F16H61/662
Filed: 1962-01-25
Abstract: 929,326. Expanding pulley gearing. W. REIMERS. Jan. 25, 1962 [Jan. 25, 1961], No. 2914/62. Class 80 (2). In an expanding pulley gearing each of two pulleys has a single movable flange urged axially by a mechanical device when that pulley is the driven pulley, and a separate hydraulic turning device to transmit torque to the pulley when that pulley is the driving pulley, the flexible driving member being held in equilibrium by the pressure in the hydraulic device which also controls the transmission ratio. Two pulleys comprising conical disc members 3, 4 and 5, 6 are substantially identical and are coupled by a link chain 11. The discs 3, 4 are rotatably mounted on a shaft 1 having a shoulder 9, preventing rightward movement of disc 3, and a cam ring 18 having a helical cam track 16 engaged through balls 20 with a corresponding track 14 on the axially movable disc 4. A sleeve 38 rigid with the disc 4 is splined to a housing 28 rotatable on the shaft 1 and having radial partitions 31 corresponding with similar partitions 27 rigid with the shaft to provide a pressure chamber 33 fed from a bore 34 in the shaft 1. A piston control valve 42, fed with pressure oil from a pump 40 through a relief valve, controls the admission and exhaust of fluid to the pressure chambers 33 through lines 55, 56; exhaust being maintained at a slight positive pressure by a second relief valve 54. The valve is controlled to vary the transmission ratio by a manual lever acting at 61 on a balance link 60 actuated at 62 by the position of the disc 6 to produce equilibrium in the system. The arrangement is such that when shaft 1 is driving shaft 2 at a predetermined ratio, the position of the flange 6 is determined by the load torque acting through the cam tracks 15, 17 and the torque through pulley 3, 4 is transmitted by the hydraulic turning device which rotates the flange 4 to prevent overrun of the cam tracks 14, 16. On torque reversal due to overrun the hydraulic device of pulley 5, 6 prevents overrun of cam tracks 15, 17 and the cam tracks 14, 16 determine the position of the flange 4.
