Title: Improved driving gear for mixing machines
IPC: B28C5/08
Filed: 1937-06-07
Abstract: 497,055. Driving-gear for mixing-machines. NEAL & CO., Ltd., R. H. (Faure, J.) June 7, 1937, No. 15708. [Class 86] [Also in Group XXIV] A self-contained driving-gear unit for concrete &c. mixing machines comprises a driving shaft 5 connected to the flywheel 8 of a prime mover, a transversely arranged driven shaft 16 for rotating the mixing drum 25 in either direction and a second driven shaft 6 for imparting a drive to a pulley 9 to operate a feed hopper. A pinion 10 on the driving shaft 5 drives a gearwheel 11 freely-mounted on a fixed shaft 4 and secured to a bevel wheel 13 which drives freelymounted bevel wheels 14 on the shaft 16 in opposite directions. A clutch member 17 keyed to the shaft 16 is adapted to engage friction surfaces on the bevel gears 14 for effecting the drive of the shaft 16 in either direction, which drive is transmitted to the drum 25 through a pinion 24 gearing with teeth 25a. Rollers 26 are mounted upon the ends of the shaft 16 for supporting the mixing drum. The shaft 6 is driven through a gear 30 from a pinion 29 which is formed on a sleeve 28 loosely mounted on the fixed shaft 4 and carrying friction cones 27, 32 co-operating with friction surfaces 12, 31 on the gear wheel 11 and the casing respectively so that it can be clutched to the gear wheel 11, or braked, by movement in opposite direction. The pulley 9 can thus be controlled to raise the feed hopper by winding up a wire rope attached thereto or to lower it under its own weight under control of the brake 32, 31.

Title: Arrangement for transmitting signals selectively to series conne ted receivers
IPC: H04Q9/16
Filed: 1972-04-05
Abstract: 1392615 Signalling on trains GERMANY MINISTRY OF TRANSPORT 5 April 1972 15743/72 Heading B7N [Also in Division G4] In a system for controlling the selective uncoupling of railway vehicles, a command message is passed through a chain of seriesconnected receivers each of which modifies the message and passes it on until the modified signal arrives at the selected receiver, whereupon the desired uncoupling is effected. In the embodiment of Fig. 1, the message consists of N 'address' pulses followed by a long interval and then an uncoupling pulse, each receiver decreasing the number of pulses by one until the Nth receiver is reached. The first pulse sets a monostable Ma and passes via lines 22, 23 and gates O3a, A6a, 08 to set a monostable M9. The trailing edge of this pulse sets a bi-stable Ba to enable gate A7a for subsequent pulses. The second pulse passes through gates A7a, 013 znd A11 to set a bi-stable B10 which enables gate A12a through which the second and all subsequent pulses pass to line b and the next receiver. The "address" pulses are followed by a long interval and then by the control pulse. The dwell time of M9 is less than the long interval, so that in the selected (Nth) receiver the last address pulse is suppressed by Ba but B10 is not set: thus the control pulse passes via gate A7a to gate Al5a and control output e. The pulses may be fed in from the other direction on line b (to Mb and Bb) and out on line a or d, the circuit operating as above, since each receiver is symmetrical with respect to lines a and b. The various switching elements in the above may operate electronically, pneumatically or hydraulically.

Such crinkling would occur when the stacks comprise a limited number of articles, say one or two newspapers. In the apparatus of Specification 1,282,257, a wrapper 6 is passed over a stack and applied around the top and sides of the stack by movement of the stack into a frame 4. The projecting front free end of the wrapper is then tucked under the stack by movement of an endless rol'er conveyer 3 after which the rear free end of the wrapper is tucked under the stack by movement of the stack and frame on to a receiving roller table where the projecting ends of the wrapper are folded around the ends of the stack. In order to prevent crinkling during tucking of the front free end, a pair of doublearmed levers 10 are provided which are pivoted, prior to the tucking operation, to a position under the front free end of the wrapper. Thus the wrapper is folded during the tucking operation around the levers rather than the front edge of the stack. Each lever is actuated in time with the conveyer 3 by an eccentric cam disc 16 carried by a sprocket 19 driven by the drive 12 of the conveyer. The disc is engaged by a roller 15 mounted on one end of the lever the roller being kept in contact with the cam by a biasing spring 18. Reference has been directed by the Comptroller to Specification 1,283,663.

Abstract: 1,172,855. Extruding composite articles; metal powders. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 12 April, 1967 [14 April, 1966], No. 16341/66. Heading B5A. [Also in Division C7] A process of forming a sintered fibre reinforced metal body comprises extruding a first plastic mixture of a metal powder and metal or refractory fibres and simultaneously extruding a second plastic mixture of a metal powder, said second extruded mixture forming a sheath in the first extruded mixture, treating the composite extrusion to solidify the plastic media and then heating to remove the plastic media and sinter the metal powder. The metal powder may be Ni, Fe, Cu, Ag or age hardenable Ni-Cr alloys and the fibres may be Si 3 N 4 , 5i0 2  or Al 2 O 3 . The plastic medium may be ammonium alginate or a cellulose derivative in an aqueous solution and the solidification of the medium is effected by gelling with a mineral acid. Alternatively the plastic media may be a thermo softening plastic e.g. methylmethacrylate or a thermosetting plastic e.g. epoxy resins. As shown in Fig. 3 the plastic mixture of powder and fibres is extruded from an inner container 1 through nozzle 5 and the plastic powder mixture is extruded simultaneously from an outer vessel 2. The composite extrusion is gelled in dilute HCl at 8 to form a tape 9 which is washed at 11, dried at 13 and 14 and sintered at 800-900 C. at 15. The sintered tape is then hot rolled at 16. Several of the sintered tapes may be stacked together and hot pressed to form composite assemblies in which the alignment of the fibres may be varied by adjusting the position of the components of the stack.

Abstract: 1425299 Fluid pressure brake systems BENDIX CORP 16 April 1974 [16 May 1973] 16492/74 Heading F2F [Also in Division F1] A vessel 32 for storing and releasing fluid under pressure comprises a housing 68 having a closed end connectible to a fluid pressure source, a composite piston 74 slidable in the housing and forming a variable volume chamber 72 with the closed end, resilient means 90 urging the piston toward the closed end and stop means 104 against which the piston is urged when the pressure and volume of fluid in the chamber have attained predetermined values respectively; the piston is responsive to an increase in volume of fluid above the predetermined value to cause volumetric expansion of the chamber and thus compensate fluid expansion due to temperature rise. The vessel which provides an auxiliary fluid source in the event the primary source of fluid is inadequate may be included in a vehicle hydraulic power brake system incorporating a power brake boost mechanism (10), Fig. 1 (not shown), connected between an engine driven pump (12) and a steering gear mechanism (14) pressurization of the fluid within the vessel (32) and release therefrom being controlled by a charging valve (34). As shown, the differential piston 74 comprises outer and inner pistons 78, 80 and admittance of pressure fluid to the chamber 72 moves the piston against the pressure of the pre-loaded spring 90 until the piston abuts the stop 104. Due to a temperature rise of the stored fluid the resultant pressure increase due to fluid expansion is effective over the differential area between the pistons 78, 80 to move the piston 78 against the pressure of the spring to compensate for the volumetric increase of the fluid in the chamber.
