Abstract: 1,263,959. Multiplex pulse signalling. STANDARD TELEPHONES & CABLES Ltd. 2 Sept., 1970 [30 Sept., 1969], No. 48096/69. Heading H4L. In a frame synchronization system for a time division multiplex system, in which one or more preselected time positions in a frame are used for sync. signals, bit streams arriving over highways H1, H2, H3 co-operate with frame sync. counters 1S, 2S, 3S, respectively, which indicate the current synchronization condition of the highways to which they correspond. The counters and corresponding highways are scanned by equipment SE, SEM, SET so that each counter and its highway are scanned at the same time under the control of pulses from the local clock, the results of each counter scan being supplied from SE to a synchronization monitor SM which also receives the output of the bit stream scanner SET. If the monitor SM finds a loss of synchronism an output is supplied to a gate GD. The bit stream scanned by SET is also supplied to a dummy sync. search unit DSS which continuously searches for the sync. code and when it finds it, delivers a pulse to a dummy sync. counter DSC. If, at the end of a monitoring period, an out-of-sync. condition has been detected the signal supplied to gate GD causes via the scanning equipment SEM the resetting of the frame sync. counter for the highway being dealt with and the transference of new sync. information from DSC. The scanning equipment then steps to the next highway.

Filed: 1964-12-02
Abstract: 1,091,767. Fluid-pressure servomotor systems. DOWTY MINING EQUIPMENT Ltd. Feb. 25, 1966 [Dec. 2, 1964], No.48994/64. Heading G3P. [Also in Division F1] A mine roof support assembly comprises a series of roof supports 1, each having at least one pilot valve 19 operable to cause its support to undergo an advancing operation and each valve being responsive to a different predetermined frequency of fluid-pressure pulses in a pilot line 15 whereby a selected roof support may be caused to advance by setting an electromagnetic pulse generator 17 to emit pulses of the required frequency in the pilot line 15. In the assembly described, each roof support has two independently operating pilot valves 19, 21 which when operated by the receipt of the correct frequency of pressure pulse, cause pressurization of respective lines 8, 11 from a supply line 5. The pressurization of the lines 8, 11 results in operation of control valve units 7, 12 which in turn control the advancing sequence of the support. Each pilot valve 19 comprises a cantilever mounted reed 23 deflectable in a transverse direction when subjected intermediate its ends to the pressure pulses in a branch pilot line 25, 22. When the frequency of the pulses coincides with the natural frequency of the reed 23, the amplitude of vibration is sufficient to open a flow path between an emitter nozzle 27 connected to the pilot line 15 and a receiver nozzle 28 forming the inlet to a cylinder 29. The subsequent pressurization of the cylinder 29 moves a spring loaded piston 31 to open a valve 32 to connect the supply line 5 to the line 8. The reed may be replaced by a flattened and twisted tube arranged to vibrate in torsion and comprising a fixed end open to the pressure pulses and a closed end which oscillates in response to the pulses to cause operation of a rotary valve.
Patent GB-1121868-A (GB)
Title: Lithographic plate and method of manufacturing same
IPC: D21H19/58
Filed: 1965-11-18
Abstract: A lithographic printing plate is produced by applying to a base sheet, e.g. high wet strength paper, a surface coating, e.g. in the form of a dispersion in water, having a solids content of 50-75% by weight and containing an inert filler (e.g. clay), zinc oxide and an ammonia neutralized polymerised acrylic acid having an average molecular weight in excess of 60 000 and sufficient ammonium ion to maintain the acid in solution in the presence of the zinc oxide, and thereafter drying the coating on the base sheet at least to a non-tacky condition without direct physical contact of the exposed surface of the coating with the drying means whereby the evaporation of the liquid solvent of the coating is effected in a region away from the exposed surface of the coating to form a continuous hydraphilic water-insoluble lithographic surface.  Drying may be effected by infra-red heaters and/or drum dryers, these latter only contacting the coating when this has been dried at least to a non-tacky condition, otherwise contacting the base sheet.  The coating composition may contain 10-13% by weight of the polymerised acrylic acid and also a dispersing agent, e.g. sodium hexametaphosphate and may be applied to the base by blade coating. The base sheet may have one or two base coatings of inert filler (e.g. clay) starch, zinc oxide and melamine resin applied thereto at the rate of 6-9 pounds of dry solids of coating composition of a first coating per 3300 square feet of paper base surface and 3-4 pounds of a second coating per 3300 square feet of surface.  The surface coating may be applied at the rate of at least 4 pounds of dry solids for 3300 square feet of surface.  Other suitable supports for the lithographic surface may be fibreboard, textile fabrics, plastic sheet and metal strips.

Title: Fluid Flow Measurement System and Method
IPC: G01F1/66
Filed: 1967-11-03
Abstract: 1,181,907. Acoustic measurement of fluid flow. WESTINGHOUSE ELECTRIC CORP. 3 Nov., 1967 [25 Nov., 1966], No. 50096/67. Heading H4D. In a system for measuring flow parameters of a fluid in a conduit of irregular cross-section, acoustic energy is repeatedly transmitted upstream and downstream to respective receiving transducers during their movement along predetermined respective paths, for each transmission a value dependent on the difference #T in travel time of the energy to the respective transducers is derived, and the values are summed. In the embodiment of Figs. 4 and 5 for measuring the average flow velocity, mass or volume flow rate, or total flow of water in a canal 10 of trapezoidal cross-section, transducers 13 and 14 are driven along tracks 15 and 16, preferably at a constant rate and such that the line joining the transducers makes a constant angle with the flow direction. Each transducer transmits towards the other and subsequently receives the pulse from the other. Circuit 45 comprises a gate which is opened on receipt of the downstream pulse and closed on receipt of the upstream pulse to feed the output of oscillator 42 to a digital counter for the interval #T which is equal to 2LV/C<SP>2</SP> (where L is the transducer spacing for a particular transmission cycle, V is the component of flow velocity in the line of acoustic propagation, and C is the sound velocity in static water). The #T counts for successive transmission cycles are summed in circuit 45 to provide a value proportional to the average flow velocity over the whole cross-section of the canal. From a knowledge of the number of #T counts and the canal geometry the volume flow rate and total flow can then be found; appropriate weighting factors are applied by circuit 45 to give read-outs of these flow parameters. Since the #T values are dependent on variations of C with the temperature and mineral content of the water, a fixed pair of auxiliary transducers 13<SP>1</SP>, 141 is provided to give an auxiliary #T count which varies with C and is used to control oscillator 42 such that the oscillator frequency is proportional to C. This results in a first order compensation for variations of C. A second order compensation to make #T wholly independent of C is provided by a circuit (56) (Fig. 7) which employs an additional oscillator and counter to correct the #T count. If transducers 13<SP>1</SP> and 14<SP>1</SP> are disposed with their joining line normal to the flow direction a simplified circuit for correcting the oscillator 42 frequency can be used (Fig. 10, not shown). The techniques for the first and second order compensations are described in detail and are essentially those disclosed in Specifications 1,166,771 and 1,180,978.
