Title: Improvements in and relating to roller conveyors
IPC: B65G47/26
Filed: 1960-06-27
Abstract: 903,999. Roller conveyers. RAPIDSSTANDARD CO. Inc. June 27, 1960 [Dec. 2, 1959], No. 22517/60. Class 78 (1). The rollers of a roller conveyer are driven by a propelling member held in driving engagement with the rollers by a vertically movable support disposed beneath the propelling member, the support being lowered to stop the drive of the rollers of one part of the conveyer in response to the presence of an article on another part of the conveyer. As shown, the rollers 12 constituting the conveying surface are driven from beneath by a belt 15 held in contact with the rollers 12 by pressure-rollers 16 and each group of four adjacent rollers 12 includes a sensing roller 12a which is normally raised slightly above the other rollers 12 with its axle 13a supported by the pivoted lever 18. Whenever an article rests on a sensing roller 12a, the lever 18 is tilted to pull the coupling-rod 40 against the action of spring 47 and thus tilt the lever 32 about its pivot pin 35. Pivotally connected at 33 to the lever 32 is a yoke 30 which carries a pair of pressure-rollers 16 normally held by the spring 47 to keep the belt 15 in driving engagement with a group of rollers 12 " upstream " of the sensing roller 12a connected to the other end of the same rod 40. The pull on a rod 40 caused by an article on its roller 12a thus lowers the appropriate pair of pressure-rollers 16 to stop the drive of an " upstream " group of rollers 12 so that pile-ups due to stationary articles are prevented and a regular spacing of articles during normal running of the conveyer is ensured. The initial pressure exerted on the belt by rollers 16 and height of rollers 12a above rollers 12 are adjustable by longitudinal movement of the supporting brackets 44 and manipulation of the nuts 43 at the end shown, or the other end, of each rod 40. Figs. 9 and 12 (not shown) depicts alternative embodiments in which both the lever 18 (as shown in Fig. 11) and the lever 32 comprise a vertical limb offset from a horizontal limb pivoted to the side of the conveyer framework. In these forms the connection 33 between the lever 32 and yoke 30, as shown in Fig. 3, is replaced by a hanger 55 joining the horizontal limb of the lever 32 to the mid-point of a modified yoke 30a (Fig. 13). Specification 873,033 is referred to.

Title: Improvements in and relating to selective radio-frequency transmitting systems
IPC: H03C1/52
Filed: 1936-08-17
Abstract: 481,962. Modulating systems. WIRED RADIO, Inc. Aug. 17, 1936, No. 22648. Convention date, Nov. 19, 1935. [Class 40 (v)] A selective radio frequency modulating arrangement in which H.F. modulated in one of a number of possible ways is transmitted to a load, includes at least one valve, e.g. 4, having an anode a cathode and several other electrodes, H.F. energy being applied to the control grid and a selective switching system being provided for controlling connections to the other electrodes whereby the carrier may be modulated in one of several ways. A source 1 of H.F. is connected to an amplifier stage 2 the output of which is applied in pushpull to the control grids of a pair of pentodes 4, 5. A change-over switch 11 controls connections of the other grid electrodes and to the anodes of the valves 4, 5 and grid electrodes 9, 10 are connected permanently in parallel. A source 46 of audio-frequency modulation energy supplies an amplifier 48 the output from which is applied either in push-pull or in parallel to the grids 13, 14 of the valves 4, 5 through the switch 11. Rectified modulation energy may be applied to the grids 9, 10 through a rectifier unit 53 and a change-over switch 55. With the switch 11 in the righthand position and the switch 55 in contact with contact 56, ordinary amplitude modulation with the anode circuits of valves 4, 5 in push-pull is obtained, output being taken from a transformer 40, 41. The modulating voltages are applied from a winding 50 to the electrodes 13, 14 in parallel. If the switch 55 is changed over to contact 54 rectified modulating energy is obtained on the grids 9, 10 and " floating carrier " modulation is obtained. With the switch 11 in the lefthand position the modulating energy is applied in push-pull to the electrodes 13, 14 from the transformer 50, 51 and the anodes 22, 23 of the valves 4, 5 are connected in parallel through a tapped resistance across terminals 27, 28 of switch 11 and through the windings 38, 39 of the transformer 40 in parallel. Suppressed carrier modulation is then obtained, control switch 55 being ineffective in this position and electrodes 9, 10 being connected directly to the supply source.

Abstract: 1,131,834. Selective printing. ING. C. OLIVETTI & C., S.p.A. 23 May, 1966 [24 May, 1965], No. 22809/66. Heading B6F. Type-wheel machines; summation and aggregation type-selecting mechanism; power assisted type-selecting actions; type-head carriages.-A teleprinter is provided with a carriage 5 on which is mounted a type carrier 26, the type characters on which are selectively displaced into printing position by vanes 101 . . . 106 (Fig. 3) which are tilted into one of two end positions, in response to a telegraph code representative of the character to be printed, so as to enable a summation mechanism to rotate and/or raise the type carrier 26 into the selected printing position. Setting of vanes 101 . . .106 causes axial displacement of lugs 119, 120 on driven members 117 which are associated with driving members of halfrevolution clutches 111 . . . 116, whereby one or the other of the lugs 119, 120 are placed into the path of driving dogs 123 disposed on the driven members 117, which cause mutilated gears 118 to be engaged by gears 122 on the half-revolution clutches 111 . . . 116. Clutches are driven by a continuously rotating fluted shaft 13. Rotation of clutches 113, 112 jointly or selectively (Fig. 3) causes shafts 77, 78 to be rotated through 180 degrees whereby cranks 74, 76, Fig. 1, which are connected to levers 72, 73, cause an aggregate movement of a transverse lever 62 coacting with a rack 37 to displace the rack which in turn through a gear 36 causes rotation of a sleeve 33 which carries the type carrier cage 28 to place one of the four type drums 23 in the printing position. Rotation of clutches 114, 115, 116 (Fig. 3) jointly or selectively causes shafts 92, 94 and sleeve 99 to rock lever 81 which in a similar manner to lever 62 displaces a rack 43, which in turn through a gear 42 rotates a shaft 42 having a further 39 which meshes with gears 41 on the type drums 23 to displace the selected character on the selected drum 23 into the printing position. Rotation of clutch 111, Fig. 1, rotates the shaft 61 through 180 degrees, which in turn rocks the crank 59 to raise or lower the type carrier 26 to present one or the other of character columns at the printing position. Clutches 111 . . . 116 are rotated, selectively and simultaneously to select the character. Impression of the type carrier against platen 6 is effected by universal bar 133 co-operating with bellcrank 134 which engages driven member 137 with clutch 136 to rotate shaft 52 whereby complementary cams 51 rock a lever 48 (Fig. 2) to impact the type carrier 26 against the platen through a yoke 46. Type-wheel construction.-Type carrier 26 comprises a cage 28 having four symmetrically spaced shafts 24 on which are mounted respective type drums 23 one end of which terminates in a gear 41 which meshes with a gear 39 passing through the axis of rotation of cage 28 and meshing with all gears 41.

Title: Improvements in and relating to friction clutches
IPC: F16D43/18
Filed: 1949-09-07
Abstract: 683,130. Friction clutches. SELF-CHANGING GEAR CO., Ltd., and MILLER, A. A. Dec. 7, 1950 [Sept. 7, 1949], No. 23158/49. Class 80 (ii). In a multi-plate clutch in which engagement pressure varies with torque, a nut 11, Fig. 1, is threaded on a sleeve 8 secured to an oil-containing casing 1 rigid with the driving shaft 2 so as to move axially under torque to apply pressure through springs 26 to the clutch reaction plate 22 and is extended to form a drum 18 carrying the outer plates 19 of the clutch, the inner plates of which are carried by the driven shaft 5, the nut itself forming the piston of a dashpot arranged so that the pressure-applying movement of the nut is retarded to minimise the effects of sudden torque increases. For this purpose, the nut 11 has restricted orifices 17 and a non-return valve 14 which permits free flow of oil through the nut when it moves in clutchreleasing direction. The pressure - applying movement of the nut is limited by a stop flange 12 while that of the reaction plate 22 is limited by stop lugs 24. Clutch engagement is effected by centrifugal weights 34 movable radially between spring-loaded guide plates 29, 31 so as to apply axial pressure via a thrust bearing 46 and plate 44 to the clutch presser plate 28. Each weight 34 comprises a set of three rollers freely mounted on a common spindle 35, the outer discs 36 being of smaller diameter than the middle disc 37 which latter fits in radial grooves in the plates 29, 31. The grooves in plate 29 are deeper than in plate 31, so that the discs 36 roll on plate 29 only while the disc 37 rolls on plate 31 only. In the form shown in Fig. 4, the piston 59 is connected to the driving casing 50 through inclined ball-ended rods 63 so as to be moved axially under torque. The piston is slidable on a cylindrical part 60 of casing 50 while its outer periphery has a slight clearance 61 from the casing, the piston being fitted with a non-return valve (not shown). In addition to the springs 74 between the piston and the clutch reaction plate 72, there are springs 76 between the casing 50 and the plate 72. Clutch engagement is effected by arcuate spring-loaded pivoted centrifugal weights 79 having inwardly-extending arms 81 with teeth meshing with a common freely-mounted ring 83. Camming balls 93 are interposed between cam surfaces 89, 90 on the casing and ring 83 respectively, so that on outward movement of the weights and consequent rotation of ring 83, pressure is applied via a thrust bearing 96 and a plate 95 to the clutch presser plate 78.
