IPC: B41F3/58
Filed: 1954-03-18
Abstract: 753,746. Cylinder printing-machines. SOC. NEBIOLO. March 18, 1954 [March 25, 1953], No. 7976/54. Class 100 (2). The cylinder 2 of a stop-cylinder press has a circumference substantially greater than the stroke of the flat bed 4, and between the end of the operative part of one impression stroke and the beginning of the operative part of the succeeding impression stroke the cylinder is driven by a drive which produces the rest period and transmits to the cylinder the angular movement necessary to bring it into position for re-engagement by the bed for direct drive. In the machine shown the bed is reciprocated by a crank 9, a connecting rod 8, and a toothed wheel 6 located between a fixed rack 7 and a rack 5 on the bed. At the end of impression a rack 11 driving the cylinder 2 anti-clockwise reaches the end of a toothed sector 12 and the cylinder drive is continued by a cam-actuated toothed sector 15 which engages a sector 13 fixed to the cylinder shaft, the motion imparted being a deceleration to stop at the position shown, and later an acceleration to the correct speed for reengagement of the rack 11 and sector 12; the stop point may be after, and the re-start point before, the respective reversal points of the bed 4. The cam mechanism shown (which may be replaced by cams acting directly on the sector 15) consists of complementary cams 20, 21 fixed to the driving shaft 10 one at each side of a free guide block 19 on which slides a slotted follower link 17 having rollers 22, 23 which engage the respective cams. The sectors 13, 15 may be elliptical, parabolic, &c., to supplement the cams 20,-21 in obtaining the required motion.

Title: Improvements in or relating to electrical protective systems
IPC: H02H7/08
Filed: 1959-03-09
Abstract: 873,809. Control of D.C. motors; controllers. IGRANIC ELECTRIC CO. Ltd. March 9, 1959 [March 10, 1958], No. 8022/59. Class 38 (3). A protective system for a skip hoist driven by an electric motor forming part of a Ward- Leonard set comprises a relay 10 which is connected in series with a group of contacts 12 . . . 26 responsive to conditions damaging to said motor, and with a further group of contacts 28 . . . 48 responsive to excess speed and abnormal location of the load. An emergency brake coil 52 is connected in series with the second group of contacts. Thus, if an overload contact in a set 24 is opened, the relay 10 is de-energized and opens its contact 10. This causes the hoist to stop in a normal manner by decreasing speed and braking. When, however, the hoist-car fails to reduce speed at a slow-down point due to circuitfailure, a contact 30 remains open, and when a limit switch 34 or 36 (depending on direction) opens as the car passes the slow-down point, the coil 52 is de-energized causing quick stoppage by an emergency brake. At the same time, the relay 10 is de-energized. A test light 56 and selector switch 58 is used for finding which of the contacts 12 . . . 26 has been opened. A similar test light 60 and selector switch 62 is used for the contacts 28 . . . 48. After the relay 10 has dropped out, a first attempt at re-energization is made by closing push-button 50. If the stoppage was caused by a momentary opening of a self-setting contact, there is no need to use the faultfinding selector switches.

Title: Improvements in or relating to the production of boranes and organically substitutedboranes
Inventor: JENKNER HERBERT
IPC: C07F5/02
Filed: 1962-03-05
Abstract: Borane is produced by mixing a boron trihalide with monosilane or an inorganically substituted silane in the presence of active carbon. The reaction, which preferably proceeds at atmospheric pressure, generally necessitates intense cooling of the reaction vessel and/or dilution of the reactants with inert gases or liquids.  It is advisable to employ a reaction temperature of 20 DEG  to 150 DEG  C., conveniently controlled by the rate of addition of reactants. The active carbon should be free from moisture and oxygen.  Very pure diborane can be produced by mixing 4 parts by volume of boran trihalide with 3 parts of monosilane at a temperature below 50 DEG C. in the presence of dry active carbon and passing the emerging gas mixture through a washer charged with an organosilane.  Halosilanes produced as secondary products can be readily converted into silanes for re-use with boron halides by reaction with an organo-boron or organo-aluminium compound as described in Specification 823,483. The term "inorganically substituted silane" is defined to mean a halosilane containing at least one hydrogen atom.  Specification 907,462 also is referred to.ALSO:Organically substituted boranes containing one or two organic radicals are produced by mixing a "boron halide" with monosilane or an inorganically substituted silane in the presence of active carbon.

Abstract: 1372412 Parking brake actuator; valves GIRLING Ltd 30 March 1972 [2 April 1971] 8552/71 Headings F2E F2F and F2V A vehicle brake control valve arrangement comprises a control valve 10 connected between a pressure source and a wheel brake cylinder, and a control valve 11 connected between a pressure source and a lock actuator unit, both of which valves 10, 11 are actuated by a common control lever 12 movement of which is constrained by a gate 13 ;the gate 13 has first and second parallel legs 1, 2 movement of the lever 12 along either of which varies the setting of the control valve 10, and first and second cross legs 3, 4 movement of the lever 12 along either of which varies the setting of the control valve 11; and the gate also includes first and second one-way latching devices 5, 6 of which the device 5 prevents movement of the lever 12 from end E of the second leg 2 into the first leg 1 except through the second cross path 4 and the device 6 prevents movement of the lever 12 from the first leg 1 into the second leg 2 except through the first cross path 3. In use during a parking application the lever 12 is moved from A to B which causes a pressure less than the maximum to be applied through the control valve 10 to the brake cylinder, such maximum being obtainable by movement from A to C. From B the lever 12 is moved to D which operates the valve 11 to cause the lock actuator unit to be relieved and thereby hold the brake applied. The brake cylinder pressure is then relieved by moving the lever 12 from D to E. To release the lock the lever 12 is moved from E to F, where it is checked by the latching device 5, to supply pressure to the actuator to relieve the lock of load, and then from F to G to restore normal pressure to the lock actuator unit to release the lock. The device 6 prevents a parking operation with insufficient parking brake effort. As shown the devices 5, 6 comprises a swinging arm lightly spring biased against a stop.
