A carding machine comprises a fibre material inlet 1, 2, 3, a plurality of worker rolls 4, 5 a suction roll 8 downstream of the drum 3 and a compressed air nozzle 7 which produces an air stream flowing in the rotational sense of the drum and tangential thereto and which transports fibres detached from the drum 3 to the suction roll 8. The nozzle 7 is directed downwardly. The range 10 in which the fibres fly is limited by a baffle 11 which extends approximately radially and closely to the drum 3. The space traversed by the fibres in flight is free of a housing and unenclosed. The fibres impinge on the suction roll 8 in an approximately vertical direction. The baffle 11 can be provided with an obtuse flange 12. Compressed air (supplied independantly of that fed to nozzle 7) can be supplied to a row of small orifices 13 positioned between the nozzle 7 and the drum 3 and can be supplied to nozzles in the baffle 11.

Abstract: 1,227,797. Automatic speed control. STEWART-WARNER Corp. Aug. 16, 1968 [Aug. 24, 1967], No.39285/68. Heading G3R. In a method of synchronizing a motor driven device with fixed frequency pulses, further pulses are generated whose frequency is dependent on the speed of the device; the two pulses are compared and their degree of overlap used to reduce the speed of the motor which normally runs faster than the synchronizing speed, the speed of the motor then rising steadily towards the normal speed until the next coincidence of pulses. The method is applied to synchronizing facsimile transmission equipment. The synchronizing pulses are transmitted between lines of video information Fig. 2a (not shown). The speed pulses are generated by a photo-cell 36, amplified and applied with the synchronizing pulses to an AND gate 43. Coincidence of the pulses causes a capacitor 58 to charge rapidly and it thereafter discharges slowly through a high resistance 64. The voltage on capacitor 58 is applied as a control voltage Ec to a variable frequency oscillator 24 feeding the synchronous motor 26. The oscillator normally generates 61À5 c/s but the maximum voltage on capacitor 58 reduces this below 60 c/s; as capacitor 58 discharges it rises just above 60 c/s, the mean frequency of 60 c/s representing synchronism. The pulses are dimensioned to avoid interference with the video signal and synchronism has to be achieved during the pretransmission period when only the synchronizing pulses are transmitted. It is also possible to run the motor normally below synchronizing speed and cause the speed to be increased by voltage Ec; switch 90 provides the necessary circuit modifications. The synchronous motor and V.F.O. may be replaced by a D. C. motor (26a) Fig. 1a (not shown) with a regulator (24a) controlling the speed in accordance with the output of a tachogenerator (94). The voltage Ec then provides an automatically varied datum for the regulator. In a complete transmitter-receiver Fig. 3 (not shown) a second pulse generating photo-cell 124 is employed to generate the transmitted synchronizing pulses. The outputs of both pulse generators are applied to a pulse blanking circuit which cancels the pulses in the video amplifier 18 preventing them appearing on the facsimile.

In processing a photographic silver halide colour material, the developed, bleached and fixed material is treated before or during washing with propionic acid, butyric acid or their alkali-metal salts; itaconic acid, aconitic acid, citraconic acids, mesaconic acid or the alkali-metal salts, anhydrides or esters thereof; or phthalic acid, phthalic anhydride or alkali-metal phthalates. The treatment enables a shorter washing time to be used and reduces staining. The acids may be added to the washing water or may be used in a hardening bath or stabilizing bath or in aqueous solution to form a bath with which the material is treated between fixing and washing.

A device for preventing wheel lock, when the brakes of a motor vehicle are applied, by controlling the hydraulic pressure in the brake circuit comprises a sensor 2 rotatable with a wheel of the vehicle and having an output providing a measure of the rotary deceleration of the wheel and a control unit 3 including a differentiating circuit to which the sensor output is applied, the output of the circuit being such as to trigger an electronic switch to actuate an electromagnetic valve 4 to reduce the pressure in the brake circuit before the wheel becomes locked. The unit 3 includes two differentiating circuits 6, 7, the output voltage of which, when a limiting value is exceeded triggers an electronic switch 8. Valve 4 includes a piston 11 slidable in a cylinder against a spring 13 under the influence of a moving coil magnet arrangement 14. When brake pedal 1 is actuated, the control unit 3 is energized by means of a switch 9 and fluid is fed to both sides of piston 11 and to the brake shoes via lines 16, 17, 19, 20. When the control comes into action the piston 11 is pushed in the direction A against the hydraulic pressure, the connection between lines 16, 19 being interrupted so that brake pressure cannot be increased, until the magnetic force balances the hydraulic pressure. If pressure in the hydraulic circuit is still too high, a connection between lines 18, 19 allows fluid to flow back to the reservoir. In a modification, the regulation is independent of the pedal pressure.

Abstract: 1,251,424. Lasers. DEFENCE SECRETARY OF. 19 Feb., 1970 [21 March, 1969], No. 14934/69. Heading H1C. A laser has an electro-optical Q switch controlled by a step waveform so that each step alters the laser cavity Q by a discrete amount and produces a laser output pulse. The laser rod L, Fig. 1, is pumped by a flash tube F, each flash being initiated by a pulse from a timing circuit activates generator G to apply a stepped waveform being separated by a time interval short compared with the fluorescence lifetime of the laser material. The Q switch comprises a Pockels or like cell P2 and a calcite polariser P1, oriented so that with a voltage applied to the cell light is not transmitted through the switch. The voltage is derived from a supply rail through a high resistance R1, Fig. 2, and the cell may be shorted by pentodes V1, V2. The timing circuit T applies two pulses to the pentodes so that first V1 then V2 conducts and a step waveform appears across the cell. The first part of the waveform renders the Q switch partially tranmitting, and the second part renders it wholly transmitting. The two laser output pulses thus produced may be made the same amplitude by adjusting R5. The time between pulses may be altered in the range 30 nanosecs to 6 Á sees without loss of efficiency. The pentodes of Fig. 2 may be replaced by cold cathode discharge tubes or by thyratrons.

Abstract: 1,264,370. Pulse circuits. MARCONI CO. Ltd. 23 Sept., 1970 [9 Dec., 1969], No. 59924/69. Heading H3P. In a triggerable pulse generator of the type in which a pulse forming network 3 comprising inductance 7 and distributed capacitance 8 is periodically charged from a current source 1 and subsequently discharged into a load 5, an auxiliary inductor 9 in series with a unidirectional conductive device 10 is associated with the network 3 whereby, when network 3 is charged a voltage is induced in the inductor 9 which causes device 10 to conduct and to clamp the voltage across inductor 9, and thus by induction the voltage across network 3, to substantially the voltage of the current source. It is explained that, without the auxiliary inductor, the voltage across the network 3 would be V+V1 where V is the supply voltage and V1 is any negative charge remaining after discharge. The network is discharged after a period following the commencement of charging equal to twice the transit time of the network, and to be recharged after a period following commencement of discharge equal to the transit time.

The apparatus may have a recording device to give a permanent record of the selections. In the particular embodiment, the apparatus may be used for playing a game and comprises a board 4 having a number of externally identical sockets 5 into which are inserted plugs A which may complete signalling circuits through the points 6 and 7 and thus result in the switching on or off of a lamp illuminating an illustration such as a diapositive, on the working surface or sounding a buzzer, or having no action at all.
