Abstract: 1,243,433. Selective signalling. TEXACO DEVELOPMENT CORP. 24 June, 1969 [17 July, 1968], No. 31726/69. Heading G4H. [Also in Divisions G1 and H3] In a pulse height digitizer an input .pulse 10, Fig. 1, if it is above a minimum level 14, is inverted 18 and amplified A1 to establish a potential on a hold capacitor corresponding to its peak height, which potential is amplified 20 and digitized by a conventional self-balancing closed loop 24, 26, 28, 30 At the end of the conversion a control trigger 16 is turned off which closes both a switch S2-to discharge the hold capacitor 22- and a switch S3-to allow a balance capacitor C2 to charge to the output level of the digitizer comparator (which theoretically should be zero) so as to act as a compensatory bias for the next digitizing cycle. The amplifier A1, a following amplifier 20 and a feed-back loop to a summing junction + (details in Fig. 2, not shown) form an operational amplifier of gain -1. In operation when a pulse height is to be sampled a switch S1 is closed and switches S2 and S3 are opened (S2 details Fig. 3, not shown). The potential on the hold capacitor 22 then follows the leading edge of the pulse and remains at its peak-reverse current flow being prevented by a diode D1-and at the end of the pulse the switch S1 responds to the output of amplifier Al going positive and opens, thereby preventing the entry of subsequent pulses until the switch is closed by control means not described.

Winding-machines. - Relates to drum winding-machines of the type described in Specifications 205,550 and 254,398 in which, as the winding- spindle moves away from the friction-drum due to the growth of the yarn package, the angular relation of the axes of the spindle and friction-drum is varied by guiding and controlling means, and comprises an arm 30, Fig. 1, to which the spindle 21 is pivoted about an axis 29 lying transversely to the axis of winding, the arm 30 being pivoted at 35 so as to swing away from the drum 15 during the progress of winding, and a cam track 40, 45, Fig. 4, which guides and controls the motion of a roller 47 so as positively to tilt the yarn spindle 21 to a determined extent about the axis 29 as it moves away from the drum 15 during winding, and positively to prevent any undesired tilting. The cam track 40, 45 is concentric to the axis 35 and is carried by an arm 38 rotatably adjustable there about to suit cone-holders 20 of different size or taper. When set, the arm 38 is secured by a bolt 42, while the roller 47 is carried by an arm 46 of the bearing-member 22 in which the spindle 21 is hinged. The spindle 21 is maintained at right-angles to the member 22 by the engagement of a projection 24 on a spring 25 in a notch 23. The member 22 is secured on the stud 29 by a split collar 31 while the supporting- arm 30 and the arm 38 are secured on the shaft 35, as shown in Fig. 2. The arm 30 swings upwardly with the cone-holder 20 during winding, and dogging-mechanism comprising a toothed sector 50, Figs. 1 and 5, attached to the arm 30 and engaged by a spring-controlled pawl 56 is provided to prevent retrogression. The sector 50 is also engaged by a spring-pressed frictiondog 65. An adjustable screw 67 serves as a stop when the cone-holder 20 is carried down against the drum 15. The cam-groove is formed with a progresively changing pitch to wind coils having an increased pitch toward the apex end of the cone so that the taper on the surface of the package gradually increases. The cone-holder 20 is tilted to maintain the surface in full contact with the drum 15 by the action of the cam-groove 45. It is also moved bodily longitudinally to the right relatively to the drum 15 and yarn-guide 10, and the resulting package has concave-convex ends, as shown in dotted lines in Fig. 4.

Title: Improvements in or relating to drinking straw and method and machine for making the same
IPC: A23P10/10
Filed: 1955-11-08
Abstract: 789,766. Drinking straws. RABIN, S. F., SCISOREK, M., and BAYARD, J. Nov. 8, 1955, No. 31908/55. Class 14 (2). A drinking straw comprises a tubular body element having resilient side-walls, a self-sustaining elongated flavour-coated strip element positioned longitudinally in said body with portions in frictional engagement with corresponding opposed inner side walls of the body, one of the elements being held resiliently distorted by engagement with the other element whereby the strip is frictionally retained in the body. In operation of an apparatus for making the flavoured straws, straws 11 are fed from a hopper 15 to grooves 36 in feeder rolls 28. Detent mechanism 35 associated with a segmented gear drive 30, 31 intermittently rotates and aligns the grooves 36 with a knife channel 60 formed by a cutting edge 55 and a wall 59. A knife 54 cuts off strips 10 from flavoured sheet material 56 fed from a container 80, Fig. 2, not shown, by means of a chain-drive 83. The knife 54 remains spaced above the strip 10, thus providing a guide into which a finger 62 is rapidly reciprocated by links from a driven shaft 32. Strips are thereby moved into the grooves 36 in which a straw has been deposited, after being compressed by a stationary member 44 which partially extends into a groove 43 at one end of the roll 28. The finished straws are ejected from the grooves by finger 39. The strip may be coated with any additive it is desired to introduce into the liquid passing through the straw.

Abstract: 1403106 Joint prostheses F C EWALD 7 July 1972 [9 July 1971] 31942/72 Heading A5R A joint prostheses for replacement of an amputated human joint comprising a male component with a convex articulating surface and a mated female component having an elongated concave surface the portions thereof which contact the male surface during flexion having the slightly greater radius of curvature and the concave surface being so shaped that, in response to the vector forces surrounding the implanted prosthesis, the male component slides thereon with continuously shifting substantial points of contact. In a knee joint a femoral cap 30 has lateral and medial condyles 31, 32; an intermedullary stem 33 and a troclear surface 34. A co-operating tibial plateau 20 has concave surfaces 21, 22 in which during joint flexure, the condyles move with combined rolling and sliding motion as the femur moves through flexion relative to the tibia. To simulate the action of a natural knee wherein the lateral condyle 31 pivots in cavity 26 whilst the medial condyle 32 moves through the anterior, posterior arc of the cavity 27 simultaneously with rolling and sliding during flexion. In an elbow joint prosthesis a huneral cap (72) Fig. 12 (not shown) co-operate with an ulnar component (73). The natural bone radial head is removed in surgery and its function preferably performed by the radial head 82 Fig. 11 b (not shown). In producing a knee joint a life size replica of a femoral cap is made of stainless steel, cobalt chromium or titanium alloys, and an # inch layer is removed from its outer surfaces. It is then pressed into softened high density polyethylene to form a tibial plateau and the two parts are held in contact whilst being moved as nearly as possible in the manner desired for the completed joint when positioned in the natural leg. To obtain a joint with minimum operating friction the mated components may be operated together to simulate natural action whilst errosion rate is measured until a minimal errosion rate is reached. The tibial plateau is adhered to the tibia by methyl methacrylate cement 17 and may also be attached by screws or pegs 18. Ankle shoulder finger and toe joints may be provided.

Title: Improvements in or relating to refrigerating apparatus
IPC: F25B49/02
Filed: 1938-11-04
Abstract: 518,055. Regulating air &c. compressors. WESTINGHOUSE ELECTRIC & MANUFACTURING CO. Nov. 4, 1938, No. 31951. Convention date, Nov. 5, 1937. [Class 8 (i)] [Also in Groups XIII and XXXVII] In compression refrigerating apparatus a control means responsive to a predetermined high difference in pressure between the high and low pressure sides renders the compressor motor incapable of being started and permits it to operate, once it is started, independently of the pressure difference, thus dispensing with the use of an unloader. As shown applied to a system for cooling air forced over the evaporator 10 by a fan 24, bellows 27, 28 connected by pipes 29, 31 to the high and low pressure sides 16, 15 respectively operate bell-crank levers 48, 42. A movable contact 54 carried by a support 56 connected to the bell-crank 48 is adapted to engage a movable contact 55 carried by a spring 57 on a lever 58 one end 59 of which is held in engagement with the bell-crank 42 by a spring 61. The contacts 54, 55 are separated when the pressure differential between the high and low pressure sides exceeds a predetermined value and break a low voltage circuit between lines' L1, L2 which includes a relay 64 and a normally closed snap switch 34 operated by the bellows 27, 28 through the bell-cranks 48, 42 lost-motion connections 46, 43, a pivoted arm 32 and a spring 33. In operation, with the switch 34 and contacts 54, 55 closed as shown a master switch 72 is closed by a thermostatic control when the temperature of the air being treated has increased to a predetermined value and energizes the relay 64 to close the switch 66 of the compressor motor 13 and a switch 67 shortcircuiting the contacts 54, 55. During the running period the contacts 54, 55 separate due to the rising pressure difference and the switch 34 will be opened to stop the compressor in response to abnormally high condenser pressure and abnormally low evaporating pressure. When the temperature of the air reaches a predetermined low value the switch 72 is opened, and during the inactive period the contacts 54, 55 remain separated preventing starting of the compressor, until the pressure difference has been lowered to the predetermined value. The system may thus be operated without an unloading device and the capacity of the motor need not be above that necessary for the running operation.

Abstract: 158,145. Down, T. M. Dec. 20, 1919. Copying-telegraphs.-In a method of telegraphic transmission of pictures by code messages, the original picture is projected, greatly enlarged, upon a subdivided screen, and is analysed square by square, account being taken if necessary, of the distribution of tone in a single square. This is done by the use of a key square such as is shown in Fig. 1. For example, if "2 " is. the symbol for black, the code signal 3E2.5 would indicate a black patch in the centre of the square designated 3E. A code for colour may also be used. The operator at the distant point sets up the picture, also greatly enlarged; from the message, and retouches it as may seem requisite. The lines on the receiving operator's screen may be non-actinic, or may be temporarly projected upon it, so as not to appear in the final reduced photograph. Pads or stamps may be used to apply the necessary tone or colour in the various squares.
