Filed: 1919-05-13
Abstract: 138,466. Forsyth, B. March 13, 1919. Grinding-surfaces; disk and like mills; roller mills.-In grinding or pulverizing ores, clinker, &c., soft-metal grinding-members having line or narrow area contact are rotated so as to have different speeds at their points of contact, particles of the pulverized material being thereby embedded in the soft metal so as to form a grinding- surface. In the form shown in Fig. 2, two frusto-conical disks 4, 5 are rotated at the same speed in opposite directions. The disks are pressed together by a spring 11, the pressure of which can be adjusted by means of screw collars 12, 13. In a modification, two rollers rotated in opposite directions at different speeds are employed.

Title: Improvements in or relating to machine for sorting articles
Inventor: BOYER JEAN JACQUES
IPC: G01N21/55
Filed: 1961-02-22
Abstract: 964,432. Photo-electric sorting apparatus. S.A. SCIPER. Feb. 22, 1961, No. 6462/61. Heading G1A. [Also in Division B8] In a machine for sorting objects, e.g. fruit or oysters, according to their size by means of a light beam intercepted to a greater or lesser extent by the object before impinging on a photoelectric cell, and including means operated by the cell to control a sorting device,the source of light is associated with an optical arrangement to produce a hollow tubular beam of light incident on the object at the examining station. In the diagrammatic arrangement Fig. 1, located at an examining station, light from an electric lamp 1 at the focus Fe of a parabolic mirror 2 is directed as a parallel beam 2a on to the objects such as OM, Om at the position YY, and with varying obstruction passes to a photo-cell 8 located near the focus Fe of a second parabolic mirror 5. The transmitter and receiver mirrors 1, 2, 5 are provided with annular diaphragms 4, 7 to limit the area of the examining beam, and also with stop discs 3, 6 obstructing the beam over a central section Zn, corresponding to the object Om of the minimum size to be detected. The light incident on a cell 8 is arranged to operate a thyratron 10, Fig. 2 (not shown), to energize a relay 11 controlling a valve 25, Fig. 4, operating a deflector 24 to divert an article 0 from a main conveyer 21 to an auxiliary endless conveyer 22 comprising a number of partially overlapping discs 23 fixed at their centres to a chain moving along a closed path. Alternatively the relay-controlled valve may control an air jet which deflects a selected object into a side passage, Fig. 3 (not shown). As shown in Fig. 4 a number of examining stations A, B, C, D are spaced along the main conveyer 21 and the biasing voltages of the associated thyratrons are set at progressively different levels so that the largest objects are selected at station A and objects of progressively smaller size are selected by stations B--D, objects which are too small to be selected being ejected from the right-hand end of the main conveyer 21. In order to sort asymmetrical objects, one or more of the examining stations, e. g. station D as shown in Fig. 4, may be provided with two or three projection-receiver arrangements 11 81; 12, 82 having mutually perpendicular axes, the corresponding photo-cells being connected in series. At each examining station the voltages applied to the lamp and photo-cell may be adjusted to suit the size of the object to be selected. Objects deflected to any one of the auxiliary conveyers 22 are transferred therefrom manually into a packing case 33, Fig. 5, resting on a frame 32 biased upwardly by a spring 36 into the position shown by dashed lines, the case 33 being lowered when full on to a conveyer band 37 by actuating a pedal 35.

Title: Improvements in or relating to jointing arrangements for high-frequency multi-layer cables consisting of alternate thin layers of metal and insulation
IPC: H01P3/18
Filed: 1955-03-04
Abstract: 771,339. High-frequency transmission systems. SIEMENS & HALSKE AKT.-GES. March 4, 1955 [March 4, 1954], No. 6511/55. Addition to 744,104. Class 40 (4). [Also in Group XL (b)] In an arrangement for terminating a transmission line comprising alternate layers of conductor and insulation, a number of layers are connected to tappings, on an impedance network so arranged as to maintain the voltage distribution throughout the layers more nearly in keeping with that required for the mode in which propagation is taking place. By this means the termination is made more efficient due to the reduction in energy loss due to conversion of energy from its existing mode to higher order modes. As described, the tappings, having appropriate impedance matching ratios, are made on the secondary of a transformer. Fig. 4 illustrates the case of a cable comprising inner and outer conductors which are both of the laminated type. Fig. 7 illustrates the case of a cable comprising a solid central core surrounded by the laminations. In this case two such cables are shown, one for each direction of transmission, the inner cores also acting as feeders for power supply to amplifiers for the system.

Title: Improved method and means for handling and transporting coal
IPC: B65D88/12
Filed: 1935-03-04
Abstract: 452,667. Load - containers ; skips. LAURENT, A., 44, Rue de la Fosse, Nantes, Franco. March 4, 1935, No. 6728. [Class 78 (iv)] An open-topped container, for transporting coal &c., of the type having a hinged door at the bottom of one of its sides, has the sides 1, 5, 6 of wire mesh or expanded metal. Across the top of the container are two parallel channel-iron braces 3 having inclined faces and each provided at the middle with a reinforced hook-receiving hole wider at the bottom than at the top. The door 7 is supported by two pintles near the top resting in vertical slots, and means are provided for lifting the door, whereby the pintles rise in said slots and pivoted catches hanging from the bottom of the door are released from engagement with the base 2 and allow the door to swing out under the pressure of the coal. The door-lifting means consists of side levers 13 pivoted to the door pintles and to a double bell-crank 14 the other arm of which is pivoted to a link 17 having a slotted curved free end engaged by the pin of a crank 18. Each crank 18 is carried by a shaft 19 the middle of which is formed with a cranked portion 21. On lifting the crank 21 by a cable or other means the pins of the cranks 18 first move with lost motion in their slots and then pull the links 17 to raise the door 7. The container may be tipped by further action of this cable, a bar being fitted across the crank-webs 21 to abut against the hook in the rear brace 3. The lost motion slots allow the crank 21 to he turned down below the container top level during storage or transport. A stop 26 prevents the door 7 from swinging too far inward.

Title: Improvements in or relating to control and protective systems for electrical apparatus
IPC: E04G7/02
Filed: 1941-05-26
Abstract: 549,679. Protective cut-out arrangements. REYROLLE & CO., Ltd., A., and FELCE, A. May 26, 1941, No. 6734. [Class 38 (v)] In a protective and control system for mining or other apparatus L which is connected to a main switch D1 over a trailing cable including a pilot circuit having, at the apparatus-end, a rectifier Kl for normally passing unidirectional current only, an earth - leakage protective arrangement for the power conductors is combined with similar protection for the pilot circuit itself. The core-balance transformer M in the main circuit has a secondary M1 connected to a leakage-relay H with its contacts H1 in the pilot circuit, and a further winding M2 in the pilot circuit. If, due to a leak between the pilot conductor B4 and the earth-sheath return, the normal unidirectional current is replaced by an alternating current, the winding M2 causes relay H to open the pilot circuit, thus de-energizing the pilot relay F and opening the main switch. In order to ascertain the location of the fault, the isolating switch Cl is opened, relay H is reset, and the isolating switch reclosed, and if the relay H again trips, the fault is in the pilot circuit since the main switch is open. The control switch K is of the type in which a resistance K2 is inserted in the running position to ensure that the main switch, when opened, cannot be reclosed without moving K to the starting position in which K2 is shortcircuited. Winding M2 may be shunted by a choke having low resistance to unidirectional, but high impedance to alternating, current, or it may be shunted by relay coil F, in which case the smoothing condenser or rectifier F2 may be omitted. There may also be provided a testswitch N and overload windings O1 ... 03, and a modification employing current-balance trans-' formers is also referred to. Transformer G may alternatively be connected to the busbars A1 ... A3 through a separate isolator operated conjointly with, or separately from, the isolator Cl.

Title: Improved method and means for stripping and stemming tobacco leaves
IPC: A24B5/12
Filed: 1932-03-07
Abstract: 377,612. Tobacco-stemming machines. UNITED CIGARETTE MACHINE CO., Inc., 2501, Greene Street, Lynchburg, Virginia, U.S.A.-(Assignees of Gooch, C. W. ; 1020, Federal Street, Lynchburg, Virginia, U.S.A.) March 7, 1932, No. 6875. Convention date, Dec. 19, 1931. [Class 130.] To regulate the amount of stem to be retained in a tobacco leaf, a cutting or creasing knife is controlled by a tension or pull force transmitted through the leaves under treatment. As shown in Figs. 1 and 4, the leaves fed into the machine are held at their butt ends by grippers 1, 2 carried by chains 81, 82, and are tensioned by being pressed between a brush 42 and a segment 29. The brush 42 is raised out of the path of the grippers by a cam 38 and then allowed to descend upon the leaves, while the segment 29 is moved into the position shown in Fig. 1 by a roller 36 which then releases the segment. The tension of the leaf retains the segment 29 in its forward position until the tip of the leaf is pulled out from between the segment and the brush, when a spring 31 pulls the segment 29, together with a finger 60, in the direction of the arrow, Fig. 1, so that the finger engages a projection 83 on an arm 58. The arm 58 moves a rod 52 to the left to cause a tooth 54 to engage a continuously rotating ratchet wheel 55, which raises the rod 52 and lifts a hook 24, Fig. 7, to release a pawl 21. The pawl is forced by a spring 23 into a continuously rotating ratchet wheel 22, which through the pawl drives a cam 16, and a sprocket wheel 15 keyed to the cam, and a chain 14 and a sprocket wheel 7 to rotate the knife 3. A roller 26, after a complete revoluion of the knife 3, falls into a depression 28 in the cam 16, so that the hook 24 catches the pawl 21 and disengages it from the ratchet wheel 22. By setting a hand-wheel 8, any length of stem may be retained in the leaf, a corresponding adjustment being made to the setting of the ratchet wheel 22 by a hand-wheel 65, Fig. 8. If desired, a definite length of stem may be removed from the tobacco leaf regardless of its length by lifting a roller 76 on the hook 24 through a pin 75, Fig. 8, carried by a gear wheel 71, which meshes with teeth 70 on a hand-wheel 65. By pushing in the handwheel 65, it is disconnected from the shaft 17 carrying the wheel 15, and the setting of the gear wheel 71 may be altered.

A strip rolling mill incorporates a 4-high stand positioned between strip tensioning units 1 and 3, the work rolls 9 of the stand being frictionally driven by backing rolls 10. The rolls 2 or 4 of each individual tensioning unit are driven at the same speed, but a constant speed ratio is maintained between the rolls of the two units. The rolls are driven through gearing from a common motor, but a variable speed gear unit may be associated with the rolls of one set, to permit adjustment of the speed ratio. The rolls are driven with a constant but adjustable value of torque, either through a slipping clutch or by a constant torque motor. Two 4-high stands may be employed, but only one stand is operative at any one time. By selecting a suitable value of driving torque for the tensioning units, a desired tension is applied to the strip during rolling and the flatness of the strip can be controlled. This control is possible by using work rolls whose crown varies with the force exerted on them by the strip.
