Title: Improved electric switching arrangement for the remote control of rotary machines
IPC: G01G23/00
Filed: 1934-11-12
Abstract: 445,952. Operating clutches. SIMON, Ltd., H., and BRIAN, J. C., Bird Hall Lane, Cheadle Heath, Stockport. Nov. 12, 1934, No. 32548. [Class 80 (ii)] [See also Group XXXVII] Mechanism for the electrically-effected remote control of machines comprises a rotary member with two interconnected levers thereon, abutment means being movable to one or other of two positions by energization automatically or at will of one of a pair of electromagnets, said abutment means being adapted to engage one or other of said levers according to the position of the abutment means and move the lever either to complete the drive to the driven member or to break the driving connection. Movement of either of the levers by the abutment means is arranged simultaneously to break the circuit containing the energized electromagnet and close a switch in the circuit of the other magnet. As shown, a pair of interconnected rings h are supported on the driving member and rotate continuously in the direction of the arrow. On these rings are supported a pair of levers j, n, on pivots g, o, the levers being connected by a lever m. Normally a toothed projection f secured to the lever j engages a cushioning spring r attached to a projection e on a shaft d so that the latter is driven. When, however, an abutment t is swung to the position shown in full lines by energization of one c of a pair of electromagnets c, c<1>, an operating face t<1> of the abutment engages a roller k attached to the outer end of the lever j. The latter is then rotated to disengage the driving projection f from the arm e on the driven shaft and at the same time a roller p on the end of the interconnected lever n is swung outwardly. This roller engages a projection 6 on one of a pair of interconnected switch plates 2, 3 carrying mercury switches in the circuits of the electromagnets c, c<1>. The circuit of the electromagnet c<1> is not, however, completed until another series-connected switch in this circuit is completed as, for example, a switch controlled by the accumulation of grain in a mill grinding bin. When this control is effected the electromagnet c<1> is energized and the abutment t brought into the dotted position in which its surface t<2> can engage the roller p. The clutching to the shaft d is then again completed and the switches returned to the positions shown. The electromagnet circuits may, alternatively, be adapted for manual control.

[Class 87 (i).] Fig. 1 shows a top plan of the tile, Fig. 2 an underside plan, Fig. 9 the top corners of two adjacent tiles in a course, and Fig. 10 a four-tile corner-joint with three of the tiles in position. The tile is of the kind having a continuous groove n, h formed by pairs of lateral ribs l, m and head ribs f, g upstanding from its upper surface, and having a raised roll c to overlap an adjacent tile. According to the invention the tiles of each set of four adjacent tiles are adapted to overlap so that the head ribs of adjacent tiles of a course meet to form joints which are staggered, Fig. 9, in the longitudinal direction of the tile, thus providing a seal against the entrance of rain &c. Any water which penetrates to the head-groove hand runs down the lateral groove n, meets a rise o whereby most of it is deflected through an opening s in the rib m on to the surface a of the tile, while any residue which runs down the raised part of the groove n is returned to the tile surface by a downwardly sloping opening p. The openings s, p and the groove n are protected from wind pressure by the downwardly directed edge d of the roll c which is adapted to bear on the flat, slightly raised margin b of the tile. The underside of the roll c is provided with a rib 7, Fig. 2, which engages, but only partly fills, the groove n of the adjacent tile. The undersurface of the foot of the tile is provided with a rib 4 to engage the groove h of the tile below, and a rib 3 to rest on its margin b. Additional short ribs 5, 6 bear on the head ribs f, g of the tile below. The lower end of the tile is curved downwardly over its entire width. A reinforcing rib 2 is formed below the groove n.

Title: Improvements in or relating to apparatus for the detection of discharges in high-power transmission channels
Inventor: SCHELISCH ERNST FRIEDRICK
IPC: H01P1/30
Filed: 1962-08-28
Abstract: 982,700. Fault testing. MARCONI CO. Ltd. July 11, 1963 [Aug. 28, 1962], No. 32979/62. Heading G1U. Apparatus for detecting corona and arcing discharges in a high power high frequency transmission line or waveguide comprises means for tapping energy from the line or waveguide, means for rejecting from the energy tapped off energy within the frequency band which the line or waveguide is designed to transmit, and means responsive to energy outside the band for indicating the occurence of discharging or arcing. In Fig. 1 energy is tapped off a waveguide by a connection 2, which is shown as a loop but is preferably a coupling hole, and passed through a filter 3 to a noise detector 4 and indicator 5. The filter 3 is preferably a length of waveguide having its lower cut-off frequency above the frequency of propagation in waveguide 1. In operation any discharge in the waveguide will produce noise signals over a wide frequency band which will be detected by the apparatus 5 and may be used to switch off the energy propagated in the waveguide. In a modification, Fig. 2 (not shown) a filter tuned to pass energy at a harmonic of the frequency of the energy in the waveguide is included between the filter 3 and detector 4. In a further modification, Fig. 3 (not shown), the output of filter 3 is fed in parallel to three filters tuned respectively to the frequencies at which peak noise signals may occur in three sections of a waveguide channel, the frequencies being different due to different dimensions, different obstacles &c. and in this way the faulty section of waveguide can be located. In another arrangement, Fig. 4 (not shown), applied to a coaxial line, the output of noise detector is supplied to a frequency spectrum analyser; this again gives an indication of the location of the fault.

Title: Improvements in or relating to planetary gear trains
IPC: F16H47/08
Filed: 1961-09-14
Abstract: 994,662. Change speed gear. FRANCAISE DU FERODO S.A. Sept. 14, 1961 [Sept. 14, 1960], No. 33053/61. Heading F2D. A change-speed planet gear for a motor vehicle providing three forward ratios and reverse comprises intermeshed planets 28, 29 which mesh an input element 24, a sun 25 which is held by a brake 3 for first and second ratios and a ring gear 26, which ring gear 26 and a planet carrier 27 are selectively clutched to an output shaft 2. As shown, the planets 28 mesh a sun 24 fast with a shaft 1, driven from an input shaft 13 either through a torque converter H and one-way clutch 21 or through a by-pass clutch 20 in which case the one-way clutch 21 overruns. The planets 29 mesh the sun 25 and a ring gear 26 which is connected through a friction clutch 5 and a dog clutch 9, 10 to the output shaft 2 for second ratio and is held by engaging the clutch 5 and a positive brake 11, 12 for reverse. The planet carrier 27 is clutched at 8 to the output shaft for first and reverse ratios. For direct drive the sun 25 is clutched at 22 to the torque converter turbine 15 and either the clutch 5 or clutch 8 or both is/are engaged. The clutch 20 may be disengaged in all ratios for fluid drive. The clutch 20 which may be engaged automatically in the absence of "kickdown" when the torque converter reactor 17 rotates forwardly and when the vehicle speed exceeds 10 km/h drives the shaft 1 directly to provide all mechanical first and second ratios and a split torque direct drive when either the clutch 5 or clutch 8 is engaged with the clutch 22. The control for the clutch 20 may include a valve controlled by the auxiliary torque of the reactor. In Figs. 4-6 (not shown), the clutch 20, shaft 16 and clutch 22 are omitted and the turbine 15 of the torque converter is connected directly to the shaft 1. In Figs. 5 and 6 (not shown), the ring gear 26 may be clutched directly to the output shaft whilst the planet carrier is clutched thereto through the clutches 5, 9, 10 or held at 11, 12.

Title: Improvements in or relating to electric condensers of the variable capacity type
IPC: H01G5/06
Filed: 1933-11-27
Abstract: 425,329. Condensers. SULLIVAN, Ltd., H. W., 72, Leo Street, Peckham, and GRIFFITHS, W. H. F., 220, Court Road, Eltham, both in London. Nov. 27, 1933, No. 33128. [Class 38 (ii)] Some or all of the plates of one system together with some or all of the plates of an interleaving system in a variable condenser are differently shaped so that the number of plates of opposite systems which are interleaved varies throughout the working movement of the condenser, the capacity being varied according to some definite law, other than linear. In the example, the fixed plates 11 are of ordinary semicircular shape. The moving plates 1-10 are shown in minimum capacity position. On rotation plate 1 is interleaved as far as the forward outer edge before plate 2 starts to enter and similarly for the succeeding plates, the inner commencing point of the leading edge of each plate being on the same radius as the outer point of the leading edge of the preceding plate. References are given in the Specification to mathematical data for calculating the shape of the edges, for smooth continuity of capacity change according to any desired law. To obviate the necessity for very narrow plates as at 9, 10, the edges of the fixed plates between which they enter may be backed off.

Title: Improvements in automatic fire-arms
IPC: F41A17/66
Filed: 1946-11-07
Abstract: 626,502. Automatic firearms. LIPPERT, H. Nov. 7, 1946, No. 33182. Convention date, Nov. 7, 1945. Addition to 612,182. [Class 92 (ii)] The invention of the parent Specification is now modified by forming the energy accumulator in two parts and by fitting the breechblock locking member 7 in a seating 8 of the breech-casing 2. The mechanism shown in Fig. 2 is duplicated, one on each side of the breech-block 4, each mechanism consisting of relatively movable parts 10, 11, both acted on by a spring.J.2. As the breech-block approaches its closed position each of its two ribs 4a strikes a lever 15 whose lower end engages in the part 11 thus moving part 11 and a rod 22 thereon to the rear, and also compressing the spring 12. A projection 11a on the rod 22 is thus moved clear of the locking member 7, which it was formerly holding down as shown, and when the part 10 is then moved to the rear by the part 11 a surface 7a on the latter causes the member 7 to rise into locking engagement with a surface 4b on the breech-block. The part 10 is then moved by the part 11 underneath the locking member 7 to support it in the locked position. On a shot being fired, a gas-driven rod 20 rotates a lever 19 whose upper end engages in a socket of the part 10. The support for the member 7 is thus removed and as the coacting surfaces of this member and the breech-block are selfunlocking, the breech-block is driven rearwards. Also, under the action of the spring 12, the part 11, the rod 22 and the lever 13 return to their original positions. In a modification Figs. 7-11 (not shown), the lever 19 is replaced by one which is pivoted on the breech-casing and which is rotated by striking against a projection on the gun cradle.

Filed: 1954-11-18
Abstract: 783,344. Ironing-machines. RICHARDSON, D. Feb. 20, 1956 [Nov. 18, 1954], No. 33370/54. Class 138 (2). [Also in Group XXIV] In an ironing or other machine a carriage 12 is reciprocated along a rail 9 in a frame 3 by being clamped alternately to the upper and lower spans of a motor-driven endless belt 7 passing around spaced pulleys 6, 8. The belt 7 straddles a pulley 15 eccentrically mounted on the carriage 12, and outer pulleys 16, 17 are mounted on spring-loaded slotted members 18, 19 slidable on the carriage, said members coacting with preferably adjustable stops 23, 24 on the frame 3. When the belt commences to move in the direction shown, the pulley 15 is turned clockwise until it wedges the lower span of the belt against the pulley 16 to clamp the carriage 12 to the belt 7. The carriage is then carried to the left until the member 18 strikes the stop 23 and is moved, against spring 20, to disengage the pulley 16 from the wedging position. The carriage 12 then stops and the pulley 15 is rotated clockwise until it wedges the upper span of the belt against pulley 17 and causes the carriage 12 to be carried to the right until it is released by the member 19 striking stop 24. The carriage 12, which has brackets 14 to support an iron (not shown) is thus continuously reciprocated across the ironing board 4, the frame 3 being rotatable about a pillar 2 and being depressed for ironing pressure, against spring action, by a hand- or foot-operated cam (not shown). The amplitude of reciprocation may be reduced to any extent required by arresting the member 18, before it reaches stop 23, by means of a handle 22. The carriage 12 is mounted on the rail 9 through four rollers 13. The pulley 6 is driven by an electric motor 5 through reduction gearing and the belt tension is adjusted by movement of the rail 9, carrying the pulley 8, on studs 10 on the frame 3. It is stated that two or more belts may be provided. According to the Provisional Specification, the eccentric pulley is replaced by a semicircular or mutilated pulley coacting with spring-loaded catches which are manually or automatically actuated to lock the pulley in an upper or lower position in which it clamps the belt against an upper or lower jockey pulley.
