Abstract: 964,170. Telegraphy. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 23, 1961 [Feb. 23, 1960], No. 6673/61. Heading H4P. In a frequency or phase shift signalling system a special frequency or phase shift is transmitted preceding the message as a start signal which from the signal detector, e.g. frequency discriminator 12, produces zero output, the detector output being rectified at 14 and applied to an AND circuit 18 so that the latter is operated only by zero output from the detector 12 and only when its other input, from a carrier signal amplitude detector 16 of short time constant indicates that a carrier signal is present. The AND circuit 18 therefore produces an output pulse during a short starting signal interval. The special frequency may be the centre frequency or a frequency at one side of the transmission bandwidth producing zero output from the discriminator. In phase shift signalling a starting phase at 90 degrees to the signal phases (at 180 degrees phase difference) may be sent producing zero output from the phase discriminator (instead of positive and negative D.C. voltages). Alternatively a carrier frequency lying at one end of the transmission bandwidth may be sent for starting, whose mean value from the phase discriminator is zero.

Abstract: 418,483. Methods of and apparatus for bottling carbonated beverages. McKENNA BRASS & MANUFACTURING CO., 1st Avenue, Pittsburg, U.S.A.-(Assignees of Moberg, E. L.) March 5, 1934, No. 6943. Convention date, March 6, 1933. [Class 125 (ii).] In a method of bottling carbonated beverages supplied under pressure to a bottling machine, fluid such as air is supplied under pressure to the machine, the fluid supply being varied directly in accordance with and proportionately to the variation of the pressure of the gas in the carbonated water supply unit. The bottling apparatus comprises a carbonating unit C connected by a pipe 2 to a bottling unit B. Air under pressure is supplied from a compressing unit A to a connection 3 on the bottle filling machine B, through a regulator unit D which controls the pressure of air supplied to the bottles to keep it equal to the pressure of the gas in the carbonating unit. The regulator unit D comprises a casing 9 in which is housed a diaphragm 10 and valve 11. The diaphragm 10 separates two chambers 12, 13 and is con. nected by a lever 14 pivoted at 15 to the valve 11. One arm of the lever 14 is longer than the other to increase the sensitivity of the device. The chamber 12 is connected by a pipe 16 to the carbonating unit, and the chamber 13 by a pipe 7 to the fluid supply unit A and by a pipe 8 to the bottling machine B. Increase in the pressure of the gas in the carbonating unit depresses the diaphragm 10 and opens the valve 11 to permit more air to enter the pipe 7, and to pass through the pipe 8 to the bottling unit B. On the other hand if the pressure in the bottle exceeds that of the gas in the carbonating unit, the diaphragm 10 is pushed upwardly and the valve 11 is closed.

Abstract: 1,045,613. Valves. DANFOSS A.S. Feb.19, 1964 [Feb. 20, 1963], No. 6996/64. Heading F2V. Fuel is supplied to a nozzle connected to a port D, Fig. 3, of a cut-off valve 16 from a pump connected to a port P of a pressureregulating valve 14; some of the pump output is returned to the input via a conduit R and a port S. The valve 14 has a piston closuremember 17 loaded by an adjustable spring 18 in opposition to the pressure in a chamber 20 open to the port P so that the member 17 assumes a position in which one face 21 controls the opening of port S and hence the quantity of fuel fed to the nozzle. The chamber 20 leads to the cut-off valve 16 which consists of a fixed seat 23 having a parallel port 29, Fig. 4, merging into a tapered port 30 and over which is slidable a spring- urged ring 31, Fig. 3; a piston 25 loaded by an adjustable spring 27 embodies a flexible insert 24 that co-operates with the end of the tapered port 30 to control flow through the seat 23 to the port D. The conduit R opens into the chamber 37 behind the piston 25. Upon starting the pump the ring 31 and an abutting sleeve 34 are moved a distance Y, Fig. 4, which causes the piston 25, Fig. 3, to travel a smaller distance X on to a stop 28; however, the sleeve 34 continues to move with the ring 31 until axial slots 35 therein open into chamber 37. If the ring 31, Fig. 4, is moved further into the dotted-line position by the fuel pressure the fuel flows through an orifice 32 between the ring and tapered port 30 to the port D as well as through the slots 35 to the conduit R and port S. The ring 31 adjusts itself in dependence on the pressure difference thereacross. Should the quantity of oil decrease the pressure drop across the orifice 32 is reduced and the valve is closed by the spring 27 urging the piston 25 to the left, which piston carries with it the sleeve 34 since the latter are frictionally coupled.

A generator comprises a tubular core 40 having a plurality of magnetizable metal strips 48 mounted thereon and angularly-spaced from one another about the axis of the core, a wire coil 50 wound around the core, permanent magnets 30 positioned around the core with pole faces located adjacent the ends of the strips which project beyond the core, and means for vibrating the strips so that a voltage is induced in the coil. As shown, the means for vibrating the strips comprises a rotatable head 22 carrying permanent magnets 24. Rotation of the head by a motor 16 distorts the flux extending between the magnets 30 and the strips causing the ends of the latter to vibrate. This vibration when transmitted along the strips, produces consequential distortion of the flux around the strips and extending through the coil. The coil has several layers, as shown in Fig. 4, and between each layer is a cylinder of brass or aluminium foil 55 . . . 59. surrounded by a layer of dielectric tape 60 ... 64, theseveral cylinders and layers of tape condensers on which a charge is built up by the field produced by the voltage induced in coil 50. The ends of the foil cylinders are connected to common leads 70, 71, Fig. 5, which, together with the output leads 72, 73 from the coil, are connected to: terminals 74, 75 connected together through an intermittently operated switch 76 and a resistor R. Motor 16 is connected across resistor R through a twoposition switch 78 also operated intermittently. In one position of switch 78, a battery 80 supplies the motor to activate the generator and produce a voltage at torminals 74, 75. It is stated that after motor 16 has been started, switch 78 is moved to its second position in which motor 16 is connected across terminals 74, 75, the switch 76 being closed long enough to permit the charge appearing thereon to be discharged through the motor after which it opens to. allow the charge to build up again. It is also stated that a further load may be connected in parallel with resistor R.
