Abstract: 1,053,685. Selective signalling. SIEMENS & HALSKE A.G. July 9, 1965, No. 29112/65. Heading G4H. In road traffic survey apparatus, detectors produce parallel coded signals indicating vehicle categories, e.g. speed, private, commercial, and after recoding, the signals operate recording apparatus, e.g. a tape punch to produce a record which is usable in conventional data processing equipment. Other information-such as timemay be entered from appropriate devices, these and the detectors being selected one at a time by line finding apparatus. When the traffic density is high, counters may be employed to record only every 10th vehicle in a given category. When the traffic density is low each vehicle category is represented by five different code combinations, the one chosen being determined by which one of five successive time intervals it occurs in, every fifth time interval being recorded, whereby the same time resolution is obtained without having an unduly high proportion of actual time recordings.

Abstract: 1,228,445. Hydraulic turbines. INTREPRINDEREA PENTRU RATIONALIZAREA SI MODERNIZAREA INSTALATIILOR ENERGETICE. April 10, 1968 [April 10, 1967], No.17172/68. Heading F1T. A method of operating a hydraulic turbine plant . having first and second control means and a speed control for controlling the speed of the turbine by varying the first control means comprises the steps of operating the first control means to maintain the speed constant and then temporarily operating the first control means as a power control to maintain the turbine output power, instead of speed, constant at its immediately previous value, varying the second control means until the minimum flow through the turbine for that power has been found, and thereafter again operating the first control means as a speed control to maintain the speed constant. The plant includes a Kaplan type axialflow turbine 25 driving a generator 26 supplying a load 27, the turbine having adjustable guide and rotor blades. During normal operation the speed of the turbine 25 and hence the frequency of the generator 26 is maintained constant by comparing the actual frequency f with a reference frequency f o  in a comparator 28, the error signal E f  causing the governor 14 to alter the angle α of the guide blades so reducing the error to zero. A proportional element 15, which may be a cam, is arranged to alter the rotor blade angle # by an amount appropriate to the change in α so as to maintain maximum turbine efficiency. When the guide blade angle α exceeds a predetermined value a transducer 24 emits a signal p causing switching elements 11, 12, 13 to switch over. Governor 14 now acts to maintain generator power, instead of speed, constant by comparing in unit 29 the actual power P monitored by a sensor 20 with a value P c  fed from a memory 21 and corresponding to the power immediately before switch over, the error signal E p  causing governor 14 to adjust the guide blade angle α until the power returns to P c . Simultaneously element 12 switches control of the rotor blade angle from cam 15 to a sampling system comprising a servomotor 16, signal generator 17, derivative element 18 and sensor 19. The element 18 compares the change in flow dQ with the change in rotor blade angle d# and the sensor 19 acts to ensure that the angle # is altered to reduce the flow Q to the minimum value for the selected power and thus increase efficiency. The signal p from the transducer 24 accordingly disappears and the switches 11, 12, 13 return to their original positions thereby returning the turbine to speed control. The change from speed to power control may also be initiated by devices 22, 23 detecting changes in the upstream and downstream water levels in excess of predetermined amounts. In a modification, control of the turbine blades is inter-changed so that the rotor blade angle # is controlled by the governor 14 and the guide blade angle α by the cam 15 or sampling system. In a further modification the sampling system is replaced by a manual control of the blade angle.

Abstract: 1,229,883. Ground testing space vehicles. FIAT S.p.A. 17 May, 1968 [18 May, 1967], No. 23625/68. Heading B7W. [Also in Division G1] In apparatus for ground testing the attitude control system 7 of a space vehicle 1, a programme unit 9 supplies input signals to the control system 7 whereby actuators 8 apply a torque to the vehicle 1 that deforms a bar 4, which deformation is converted by a pick-up device 5 into an electric signal from which a data processing unit 6 calculates the angular displacement that would be undergone by the vehicle in free flight, signals representing this information then being compared with the input signal from the unit 9. In the embodiment shown, the space vehicle is movable in a fluid bearing 2 about a single axis. In a modification (Fig. 2, not shown) three degrees of freedom are provided in that a partially spherical member attached to the vehicle moves on a fluid cushion in a partially spherical cavity. In the embodiment of Fig. 3 (not shown), a device simulates a celestial reference and a sensing device sends to the control system 7 signals representing the variations in the vehicle attitude with respect to the simulated celestial reference. For simulation of relative motion between the space vehicle and the reference, a computer processes signals from the actuators 8 and transmits signals that move the reference device mechanically.

A movable part of an injection mould on a platen 8 is closed on to a stationary part, not shown, in two stages by an hydraulically operated piston and cylinder 5, 1; in the first stage pressure liquid supplied at 17 to chamber 6 moves the piston and hence the platen, which is connected thereto by rods 9, during which liquid flows from chamber 7 to chamber 6 via a bore 22 in the piston which houses a slidable valve sleeve 36. When the mould approaches the closed position a pin 20 operates a switch to open a valve 19 to connect the chamber 7 to exhaust, e.g. a liquid supply reservoir; at the same time a valve member 38 on a valve stem 23 enters the valve sleeve to close the bore 22 whereupon the second closure stage is effected. The platen 8 is retracted by hydraulic pistons 14 connected to the platen 8 by rods 15, and during this retraction hydraulic liquid is transferred via the piston bore to the chamber 7. A screw 23<SP>1</SP> provides an adjustable stop for the valve stem 23 which is slidable through the cylinder cover 4. In the embodiment of Fig. 3 the valve sleeve 22 is spring-urged against one end of the piston so that the transfer of liquid from the chambers does not displace it. The valve member 45 is adjustably supported in the cylinder end wall and the piston-rods 15 are coaxial with the rods 9.
