Title: Improved synchronizer clutch mechanism
IPC: F16D23/06
Filed: 1962-08-17
Abstract: 955,937. Positive clutches; change-speed gear. FORD MOTOR CO. Ltd. Aug. 17, 1962 [Oct. 23, 1961], No. 31716/62. Headings F2C and F2D. A split-spring ring synchronizer 90 is carried by a clutch element 86 and is maintained in position by extensions 94 of clutch teeth 70. The ring is provided with tapered friction surfaces on its outer periphery which are engaged by the inner periphery of clutch teeth 76 of an axially slidable clutch sleeve 74 when it is shifted to engage the clutch teeth 70. An anvil 98 has a portion 100 situated in a gap 93 in the synchronizer ring 90, and when the ring is engaged and contracted by the sleeve 74 it rotates therewith until one end of the ring engages the portion 100 of the anvil and shifts the anvil to engage a shoe 110 or 116 fixed to the end of an undulated spring 122. The spring is thus shifted and the other shoe 116 or 110 engages an anchor member 106 which is fast with the clutch element 86 which is thus caused to accelerate or decelerate until the speed of the clutch element 86 is the same as that of sleeve 74. During the synchronization interval the spring 122 is also expanded radially and acts upon the synchronizer ring 90 to augment the synchronizing action. The teeth 76 are formed with a recess 128 which is engaged by the apex defined by the friction surfaces of the ring 90 when the clutch teeth 70, 76 are engaged, in order to resist disengaging movement of the sleeve. The ring 90 may be pre-stressed. In a modification the shoes 110, 116 at the ends of the spring 122 are dispensed with, the ends of the spring being bent over to engage the anvil 98 and the anchor 106. In another modification the spring 122 is replaced by a number of arcuate spring segments separated by spacers which transmit tangential forces to the next segment. The clutches may be employed in a constant-mesh change-speed gear comprising an input gear 20 meshing a countershaft gear 52 fast with gears 54, 56 meshing gears 30, 40 clutchable by synchronized dog clutches to an output shaft 28. A synchronized dog clutch 72, 76 connects the input and output shafts for direct drive, and a gear 58 is axially slidable to engage a reverse idler which meshes a countershaft gear 60 for reverse.

Filed: 1928-11-12
Abstract: 325,475. Johason, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Nov. 12, 1928. Ammonia, catalytic oxidation of.-Nitrous oxide is prepared by the catalytic oxidation of ammonia. Ammonia, mixed with oxygen, air or gases containing oxygen, preferably in excess of that required to produce nitrous oxide, is passed over a catalyst such as platinum, iron oxide mixed with bismuth or manganese oxide, or copper oxide mixed with manganese dioxide to which silver may be added, heated to a temperature below 550‹ C. and preferably between 200 and 400‹ C. The gases are passed over the catalyst at a low speed whereby reaction products practically free from higher oxides of nitrogen are obtained, the higher oxides being obtained if the speed is increased. Nitrous oxide may be separated from the reaction gases by compression or cooling or by absorbents or solvents. A reaction mixture rich in nitrous oxide may be obtained by passing the gases in succession through several catalyst chambers, ammonia being added at intermediate stages, or, when using pure oxygen, by passing the gases in a closed circuit over the catalyst part of the gases being withdrawn from one part of the circuit and fresh gases added at another part. Specifications 4080/99 and 19074/00 are referred to.

Title: Improvements in or relating to paper machine calender stacks
IPC: D21G1/00
Filed: 1958-10-16
Abstract: 881,239. Calenders for paper. BELOIT IRON WORKS. Oct. 16, 1958 [Jan. 29, 1958], No. 33068/58. Class 96. The rolls 29 of a calender stack of a papermaking machine are mounted in bearings 29a supported by arms 29b, 29c from pivots P secured to the machine frame 11. The bearings of the rolls can be raised for shut-down or servicing by overhead lifting links L, and also, some or all of the load may be supported, e.g. by the arrangement illustrated, i.e. by a pneumatic cylinder 45, the piston 45a of which exerts pressure against an arm 29d having a pivot 43 at one end and a hemispherical cap 47 at the other, a cable C being threaded through the cap 47 so that the cap may move upwardly along the cable, but its downward movement is limited by a spherical stop S which is in two halves 50a, 50b which clamp together on to the cable C. Pneumatic pressure at 45 thus urges the bearing 29a upwardly with slight movement about pivots P, 43, 44 and 46.
Patent GB-620175-A (GB)
Title: Improvements in or relating to calculating, accounting and similar machines
IPC: G06C7/10
Filed: 1946-11-07
Abstract: 620,175. Calculating-apparatus. NILSSON, R. S. Nov. 7, 1946, No. 33103. [Class 106 (i)] The carriage of a calculating machine is moved step-by-step in one direction under the action of a spring and returned to its initial position by a second spring. A bracket 9 contains number of rollers 10, one under each key 3, so that when a key is depressed its end engages the corresponding roller and moves the bracket rearwards. This, via a connection 13, depresses a bell-crank lever 12 which releases a comb 1a and allows the carriage 4 to move one step to the left under the influence of a spring 37. One end of the spring is fixed at 38 and the other fastened to a pin 39 on the end of a bell-crank lever 40, the pin bearing against the end 43 of an operating bar 33, which is connected via a pin-and-slot arrangement 30, 31, a lever 27 and a link 28 to the carriage. At the end of the setting operation the main shaft 5 is rotated anticlockwise (Fig. 1) moving cams 16 and allowing type sectors 6 to be moved by springs 17. The noses 23 of the sectors move down until they abut the displaced setting elements (not shown), and a sector stop latch 24 engages a slot in a rack 25 to prevent the carriage returning. At the same time a release arm 44 is swung upwards and a pin 45 on it lifts a sector 47 which turns a bell-crank lever 41 and moves the pin 39 away from the end 43 to engage a shoulder 53 on a locking lever 52 which is urged upwardly by a spring 54. The spring 37 and a spring 50 connected between the pin 39 and a pin 51 on the operating bar 33 are thus tensioned. Subsequent clockwise rotation of the main shaft transfers the reading to the totalizer wheels, and the cams 16 and 19 return the type sectors 6. When the noses 23 are all clear of the carriage setting face 4a a balance weight 26 lifts the latch 24 and the carriage is returned to its initial position by the spring 50 which pulls the bar 33 rearward. Clockwise rotation of the main shaft also swings the arm 44 downwards and this depresses the locking lever 52 allowing the spring 37 to pull the pin 39 against the end 43 of the bar 33. Instead of employing the arm 44 to release the locking lever, the bar 33 may have a pin at its rear end which rides on a cammed surface of the locking lever to depress it.

Abstract: 1422052 Image pick-up tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 25 Jan 1973 [28 Jan 1972] 33180/75 Divided out of 1422051 Heading HID An elongate TV camera tube comprises a target 4, an electron gun to produce a beam scanning the target due to a magnetic field within a portion of the tube, a qauze electrode 5 adjacent the target and an odd number of at least three substantially straight, elongate gauze-electrode connection conductors (one at 6) extending along the inside of the tube to contact the gauze electrode, the conductors being disposed uniformly about the axis. Three straight gauze connectors, when part of an electrical loop for applying direct voltage between gauze and target, can suppress all interference signals originating from twopole, four-pole, eight pole &c. fields, independent of the angular position of the tube. An odd number of gauze connection wires greater than three may inhibit interference caused by all multiple fields and also be insensitive to the angular and axial positions of the tube in the deflection field. The gauze connection wires may be between a pair of sleeves in the tube which sleeves respectively encircle the gun and support the gauze. Reference is made to fourpole fields for deflection amplification. Target 4 may contain a photoconductive material such as antimony trisulphide or lead monoxide or a disc of semi-conductor such as Si with a mosaic of P-N junctions. Gauze 5 may be a few mms. from target 4. Coil system 9 provides line and deflection fields, and the beam is magnetically or electrostatically focused. Ferromagnetic screen sleeve 10 may be of Mu-metal (Registered Trade Mark). Gauze supply 12 (part of which may be the camera chassis) and target supply 13 are interconnected by conductor 11 and resistor 14 provides the video-signal. Conductors 6 and 11 form loop 16 with capacitive interruption 17 and similarly the gauze conductors paralleled with conductor 6. In shaded area 19, coil system 9 may generate a deflection field returning in sleeve 10 (denoted as circles 21). Reference is made to colour TV cameras of three tube type.
