Title: Improvements in or relating to open wire carrier current transmission systems
IPC: H04J1/18
Filed: 1946-09-04
Abstract: 616,459. Telephone transmission circuits. STANDARD TELEPHONES & CABLES, Ltd., and THORNTON, A. M. Sept. 4, 1946, No. 26555. [Class 40 (iv)] An electric carrier current transmission system comprises means for transmitting over a circuit a side-band occupying a broad band, means for transmitting over the same circuit two or more separate side-bands simultaneously, all lying within the frequency range of the firstmentioned side-band and being inverted with respect to it, and switching means to connect either the first- or the second-mentioned means to the said circuit. A multiplex system connecting two stations A, B employs a lower band of frequencies for sending in direction A-B and a higher band in direction B-A. As shown in Fig. 1, adjacent lines using systems (a) and (b) respectively employ the lower sidebands 1, 2, 3 derived from carrier waves represented by the adjacent full-line arrows to transmit from A-B, the side-bands in the two systems being relatively staggered. In addition, six telegraphic frequencies, represented by a square, can be employed simultaneously. Alternatively, either line may be used to carry the upper side-band of a broadcast with the minimum of cross-talk. For the direction B-A, the lower side-band of the broadcast and the upper side-bands of the telephone channels may be employed. Known circuits and switching means are employed (Fig. 2, not shown) to feed line terminating circuits at each station, the two stations being connected if necessary by repeaters. Fig. 10 shows part of a repeater circuit modified to bring out the broadcast or one of the other channels. Four coil bridges 69A, 69B, 70A, 70B form balancing networks adapted to divide the energy from the input circuit between two output circuits in any desired proportions. If it is desired to drop off the broadcast channel, a broadcast receiving circuit is connected to branch rA or rB according to whether it is to receive from station A or B. To drop off a telephonic or telegraphic channel received from station A lines rA, tA are connected to an appropriately tuned channel terminal circuit, Figs. 5, 6 (not shown). Specification 558,758 is referred to.
Patent GB-1152061-A (GB)
Title: Pelleting Apparatus
IPC: G05D15/01
Filed: 1966-06-14
Abstract: 1,152,061. Tabletting machines. UPJOHN CO. 14 June, 1966, No. 26559/66. Heading B5A. [Also in Divisions G1 and G3] In a rotary table, multiple die, opposed plunger pelletizer machine for producing tablets by compressing powder in a die, the applied force is measured by a first strain gauge, and the force required to eject the tablet by a second strain gauge. As shown (Fig. 2), the powder is fed into a die between an upper punch 1 and a lower punch 2, mounted with others on a rotating table. Compression is produced by pressure rollers 14, 41. The former is eccentrically attached to a shaft 12, carrying at the other end a crank with a roller 21 resting on a crosshead 23. An identical assembly is mounted on the other side of the crosshead 23, and the complete unit is supported by a plunger 24 urged upwards by spring 26 and fluid pressure F, counterbalanced by screws 28, 29 bearing on the rollers 21, 22. As the table is rotated an upper punch 1 is forced down by roller 14 as its mating lower punch 2 is raised by an eccentrically mounted lower pressure roller 41, to compress a predetermined quantity of powder fed between them. During compression, roller 14 is partially rotated, reducing the strain in screw 28, and this change in strain is measured by a semi-conductor resistance strain gauge 31 (Fig. 4) bonded to the screw, and associated with a similar strain gauge 84 and two static resistors 83, 86 in a bridge circuit 32 whose output is indicated on a CRO 39 or a recorder. Ejection of the formed tablet is effected by the lower punch 2 passing along a ramp 51 (Fig. 6) secured to a flange 53. A block 56 is mounted below the flange, carrying screws 59, 61 which protrude through holes in the flange to abut the pump 51. Thus as the lower punch 2 is forced up the ramp, the force needed to eject the formed tablet increases the compression on screws 59, 61 and is measured by a strain gauge resistor 71 mounted on screw 61 and connected in another bridge circuit. The measured compression force in the punches may be averaged and compared with a reference value to regulate (a) the compression force (Fig. 9, not shown) by adjusting the vertical position of roller 41, (b) the volume above punch 2 to be filled with powder (Fig. 10, not shown), by adjusting the vertical position of punch 2 when the powder is introduced, (c) the quantity of powder for each tablet by adjusting the pressure of a fluid controlling the powder feed (Fig. 11, not shown).

Title: An improved method of and apparatus for moistening rotatable packages, such as yarn cops and bobbins
IPC: D06B1/00
Filed: 1953-09-28
Abstract: Yarn cops or bobbins are moistened by passing them through a chamber wherein water is sprayed on to them, the cops or bobbins being conveyed through the chamber by means which simultaneously causes them to rotate about their axes.  In a first arrangement, Figs. 1 and 2, the cops or bobbins are placed within a hopper 1 from which they fall on to a comparatively slowly rotating disc 3. From this they pass to a more rapidly rotating disc 7, being held by a wall 8 at the innermost edge of the disc until the outlet channel 8a is reached. The cops or bobbins are turned so that they progress axially along the channel 8a and hence, due to the rotation of the disc 7 they also rotate about their axes.  Water is sprayed on to them in the channel 8a.  In the embodiment of Fig. 4, the cops or bobbins in the hopper 1 pass to a first conveyer belt 15a, thence to a more rapidly moving belt 15b and thence to a yet more rapidly moving belt 15c from which they pass, suitably spaced apart, into the treatment chamber 22.  The cops or bobbins are directed to be moving axially before they pass into the chamber 22 which contains the spraying nozzles 10 and also a rotating drum 20 and an inclined guide rail 21 by means of which the cops or bobbins are made to progress from one end of the chamber 22 to the other and simultaneously rotate about their axes.  In addition, a further set of spraying nozzles fed from a pipe 23 and spraying on to the drum along the line at which it makes contact with the cops or bobbins is provided to prevent threads from sticking to the drum.  In one modification, Fig. 7 (not shown), the belts 15 are replaced by a large number of rollers while in another, Fig. 8 (not shown), a hollow rotating cylinder serves both as the rotating drum 20 and as the treatment chamber 22, the cops passing within the cylinder.  In a third <PICT:0739130/IV (c)/1> <PICT:0739130/IV (c)/2> <PICT:0739130/IV (c)/3> <PICT:0739130/IV (c)/4> embodiment, shown in plan view in Fig. 12, the cops or bobbins from the hopper 1 are guided across a conveyer belt 30 by means of guide rails 31 on to a second conveyer belt 34 which they cross at an angle so that rotation of the cops or bobbins also occurs.  The cops or bobbins are sprayed while crossing the belt 34 and are then conveyed away by the belt 36.

Title: Liquid fuel control valve assembly
Inventor: FLEMING WILLIAM
IPC: F02C7/232
Filed: 1952-10-27
Abstract: 739,076. Gas turbine plant. LUCAS (INDUSTRIES), Ltd., J. Oct. 23, 1953 [Oct. 27, 1952], No. 26885/52. Class 110 (3). [Also in Group XXIX] A control valve assembly for controlling the supply of liquid fuel to the atomizer of an enginestarting turbine comprises a spring-closed closure member d controlling communication between a fuel supply passage b and a return passage f, a spring-closed closure member h controlling communication between the passage b and a cylindrical chamber having an outlet o to the atomizer and a drain outlet q, a spring- loaded valve piston m slidable in the chamber j to control the inlet i to the chamber and also the drainage outlet q, and a pair of solenoids or electromagnets t, u for imparting opening movements to the closure members d, h respectively. After both solenoids have been energized and the supply pump started, a restricted flow of fuel passes through the valve seat c to the return passage f but the piston m maintains the inlet i closed after a predetermined time, the solenoid t is de-energized due to the operation of a time switch and the closure member c engages its seat c. The sudden rise of pressure thus caused in the passage b is sufficient to open the passage i so that fuel then passes to the atomizer. At the same time the piston m engages a seat r to cut off the drainage outlet q. Once the passage i is open, the fuel pressure acting on the full area of the piston m keeps it open. To interrupt the fuel supply to the atomizer the solenoid u is de-energized by opening a further switch. If sufficient clearance is provided between the piston m and the wall of the chamber j, the passage p between the outlet o and the drainage outlet q may be dispensed with.

Filed: 1968-06-07
Abstract: 1,167,450. Motor vehicle transmission gearing. BOISE CASCADE CORP. 7 June, 1968 [7 June, 1967], No. 27237/68. Heading B7H. [Also in Division F2] A differential gear for distributing drive between the axles of a motor vehicle and permitting overrun of either of two driven members 34, 36 comprises facially toothed clutches 57, 58 between a central driving element 24 fast with a driving shaft 45 and two driven elements 28, 29 splined, through a sleeve 33 and directly, to driven members 34, 36 and moved axially outwards, against springs 41, 42 to disengage either clutch when the corresponding driven member overruns, by inclined facial camming teeth 61, on the driven elements 28, 29 meshing similar teeth 62 on opposite faces of a freely rotatable but axially fixed outer cam ring 26, and hold-out rings 30, 31 carried by the driven elements cooperated with the cam ring 26 to maintain clutch disengagement whilst overrunning continues. The hold-out rings 30, 31 are connected to the driven elements 28, 29 by spring rings 32 which permit relative rotation whilst preventing relative axial movement therebetween. Axial projections 69 on the hold-out rings 30, 31 normally engage with limited circumferential movement in slots 71 in the central cam 26. When, on overrun, the driven element is cammed away from the driving element the projections 69 are moved axially out of the slots 71 and friction drag between the driven element and its corresponding hold-out ring rotates the projections 69 until they engage radial projections (66) on the driving element 24 whereupon the projections 69 are out of register with the slots 71 and abut the sides of the central cam 26 to prevent clutch re-engagement until overrun ceases and drags back the hold-out ring. The clutch teeth 57, 58 have sufficient circumferential clearance to permit the clutch disengaging movement. The driven member 34 is a shaft which drives the front axle whilst the driven member 36 is a gear driving through a parallel shaft (39) tandem rear axles (14, 15).
