Abstract: 1,252,684. Feeding tobacco. M. L. STRYDOM. 16 May, 1969 [22 May, 1968], No. 25224/69. Heading A2C. [Also in Divisions B8 and G3] Tobacco or other material fed from a hopper 3 onto a variable speed endless conveyer belt 4 is conveyed between a pair of plates 6, which measure the dielectric constant and hence the mass of the material, the output being used to control the speed of the conveyer in a sense to keep the mass rate at a predetermined value. The tobacco is then fed onto a constant speed endless conveyer belt 7 and is thereby delivered to a stationary plate 8 having an angled discharge edge (9) Fig. 2 (not shown), for delivering the tobacco to a further conveyer (not shown) driven at a faster speed than the conveyer 7. The angle # of the edge (9) is such as to smooth irregularities in the mass rate of the tobacco caused by the varying speed of the conveyer 4 and is calculated from tan #=W, D where W is the width of the tobacco stream and D=T f  V, where T f  is the response time of the speed control system of the conveyer 4 and V is the speed of a finitely short length of material taken transversely of the material passing the plate 6 at the said constant rate. In alternative embodiments the conveyer 4 may be driven at a constant speed and the area of an orifice 5 varied to control the mass rate and the plates 6 may be replaced by a neucleonic detector.

A switching filter whose switching frequency is to be synchronized with a frequency of an input signal has a control loop which comprises: a controlled oscillator 22 providing the switching signal; a phase discriminator 28 fed with the oscillator and filter outputs; and control means for bringing the oscillator within the coverage range of the discriminator and maintaining within that range if the filter output corresponds to predetermined conditions. If the oscillator is not within the coverage range, a logical " 1 " signal Q opens gate 36 to feed a sweep signal from generator 38 to sweep oscillator 22 by varying varactor 23. When the frequency of the oscillator 22 is sufficiently near to the input frequency the output from comparator 28 passes through AND gate 32 to open gate 34 and close gate 36. The comparator output then controls the oscillator in place of the sweep signal. If the level of the rectified filter output is less than a threshold set by 26, or if the error signal from comparator 28 is outside limits set by 30, then the output Q from AND gate 32 becomes " 0 " making Q " 1 " to restart the sweep.

Abstract: 1289307 Reducing vibration in floating structures NATIONAL RESEARCH DEVELOPMENT CORP 8 Dec 1969 [10 Dec 1968] 58600/68 Heading B7S [Also in Division F2] An apparatus for damping engine-induced or wave-induced vibrations in the hill of a floating vessel, particularly an oil tanker, consists of a damped mass-spring system in which the spring is constituted by gas and both the mass and the damping medium are constituted by liquid. The gas is trapped in a receptacle partly filled with the liquid, the receptacle being so constructed that the gas expands and contracts as the liquid is displaced in response to vibrations of the hull. Fig. 2A shows one of two such receptacles which are arranged on opposite sides of the fore- and-aft axis of a ship, preferably amidships. Hull vibrations will cause the liquid surface 50 to rise and fall thereby varying the gas pressure in the space above the surface 50 and between the walls 24. The valve 38 may be closed, with an over-pressure in the space above the surface 50, the valves 40 being open so that the space above the liquid surface 52 is at atmospheric pressure. However, the spaces may have any suitable pressure (positive, negative or atmospheric) subject to the condition that the pressure in at least one entrapped gas space will vary with liquid movement. The receptacle shown is a modified ballast tank designed for use with water as the liquid and air as the gas. In an oil tanker, the vessel's own oil tanks may be modified for use as vibration dampers, the oil itself being the liquid employed and nitrogen being the gas. In Figs. 4 to 6, which are transverse sections of ships, dampers are incorporated which respectively damp vertical, transverse and torsional vibrations, liquid displacement causing expansion of gas in pockets 90, Fig. 4; 148, Fig. 5; and 348, Fig. 6. A complete vibration damping system for a ship may comprise a combination of the dampers shown in Figs. 4 to 6, tuned (by appropriate adjustment of the gas pressure and/or volume) to appropriate frequencies. In particular, a damper tuned to the engine frequency may be located at the stern and one tuned to wave frequency located further forward.

Abstract: 1294956 Radio signalling ROBERT BOSCH ELEKTRONIK GmbH 20 Feb 1970 [22 Feb 1969] 8312/70 Heading H4L In a calling arrangement for radio telephony, in which a calling signal consists of a sequence of audio-frequencies, a plurality of resonant circuits tuned to the audio-frequencies forming the calling signals are switched into circuit under the control of a counter, a single counter being used both for transmission and reception of the calling signals. Reception of calling signal.-As shown in Fig. 1, the subscriber's station normally is prepared to receive a calling signal with the counter 22 at its start position supplying an output 24 and bi-stable 35 supplying an output 49 so that transistors 18 and 21 are conductive to tune the circuit 7, 8 to the first audio-frequency of the sequence. The calling sequence, demodulated at 45 is fed via a limiter 9 and coupling coil 10 to the tuned circuit 7, 8. If the first audiofrequency is correct the output of the tuned circuit is rectified at 30 and supplied via normally closed switch 32, delay 31 and OR gate 33 to step the counter 22 to its second position, and to set a monostable 34. This opens transistor switch 18 and closes switch 19 so that the circuit 7, 8 is tuned to the second audio-frequency of the sequence, which if it is correct, causes the circuit 7, 8 to be tuned to the third and last audio-frequency. If the third audio-frequency is correct, the counter is stepped to position 4 and the resulting output via delay 36 returns the counter to its initial position and via a lead 59 triggers a bi-stable 38 to switch on a warning lamp 42 and connect the loud-speaker 47 via switch 46. When the conversation is terminated, a switch 41 is manually operated to reset the bi-stable 38 and mute the receiver. If an incomplete calling signal is received the monostable 34 is reset to its stable state and returns, the counter to its initial position. Transmission of calling signal.-To initiate a call the call button 37 is depressed momentarily to set a bi-stable 48, thereby to change over bi-stable 35 to open switch 21 and close switch 17. The output of bi-stable 48 also opens switch 32, opens switch 5 to disconnect microphone 6, closes switch 29 to switch on an audio-frequency oscillator 12 whose output frequency is determined by the circuit 7, 8 and starts a multivibrator 40. Initially, the counter 22 is at position 1 so that transistor switch 14 is conductive, the resulting audio-frequency modulating the transmitter via input 70. The counter 22 is stepped up at each period of the multivibrator 40 whereby the transmitter is modulated by a predetermined sequence of audio-frequencies forming the calling signal. When the counter reaches position 4, the counter is reset to its start position via delay 36 and bi-stables 35, 38, 48 are also triggered to their other stable state. This reconnects the microphone, disconnects the oscillator 12, closes switch 32, connects the loudspeaker and switches on the lamp 42. When the conversation terminates the switch 41 is operated to return the circuit to its normal state prepared to receive a call.

Abstract: 1295840 Inverter WESTINGHOUSE BRAKE & SIGNAL CO Ltd 6 Nov 1970 [26 Nov 1969] 57921/69 Heading H2F [Also in Division H3] In a self commutating inverter circuit for use with a resonant load 6, an auxiliary commutating device 8 is provided. The inverter comprises four bridge connected thyristors 1 to 4 connected between a D.C. supply in the load. When the inverter is first switched on the oscillations in the load are insufficient to commutate the thyristors. To commutate the thyristors at starting, a capacitor 87 in parallel with an auxiliary voltage source 89 and resistor 88, is connected to thyristors 81 to 84 connected in a bridge configuration. These thyristors are switched to provide a conducting path to capacitor 87 at the point when commutation is required. These thyristors short across the D.C. supply cutting the current through the thyristors 1 to 4. The capacitor 87 is charged in the reverse direction during this process so that the commutating action of the auxiliary commutating device is decreased over a number of cycles following starting. The inverter is started by triggering thyristor 91, as soon as the current through the sensor 94 reaches a predetermined value; main inverter thyristors 1 and 3 are triggered by pulse generator 15. During operation the thyristors 1 to 4 and 81 to 84 are triggered by the oscillations generated in the load which are detected by control circuit 10 which in turn activates pulse generators 11 and 12. In a Fig. 4 (not shown) an additional voltage source 16 is provided and diode 17 is connected across circuit 8; auxiliary commutation is provided during the conductive period of diode 17.
