To form buttonholes in the length of braid, plates 30 on a chain 12, driven from the common drive to the bobbin driving gears 18 and take-off mechanism, move switches 4 to the position of Fig. 1, to divide the raceway into two parts. Half the bobbins then circulate in one part and half in the other part. The length and spacing of the buttonholes may be varied by arrangement of the plates 30 on the chain 12. The plates 30 operate a slide 33 connected with one of two interconnected spindles 5 bearing the switches 4, by way of magnifying lever 35 and links 37, 38. A spring 41 tends to restore the noses 7 of the switches 4 to notches 8, in which position they guide all bobbins along the whole raceway. The plates 30 are in the form of trapezia, as shown, to allow them to pass around the sprockets over which the chain runs. Longitudinal cores are fed through holes 11.

Title: Improvements in or relating to the conversion of hydrocarbon oils in the presence ofpowdered contact materials
IPC: C10G11/18

Abstract: 544,366. Cracking oils. STANDARD OIL. DEVELOPMENT CO. Aug. 21, 1940, No. 13275. Convention date, Aug, 31, 1939. Addition to 542,989. [Class 32] In the process for the catalytic cracking of hydrocarbon oils according to the parent Specification, petroleum coke is used as the absorbent and abrasive contact material. Gas oil having a boiling range of 450-1400F. is vaporized in a tubular furnace 2 and the vapours are mixed with with a dispersion of coke in steam from the chamber 4. The mixture is cracked at 1000F. and at 100 lb. per square inch pressure for ten seconds in a coil 6. The cracked products pass through line 8 to a cyclone separator 9 and the separated coke passes downwardly over baffles 11 while being treated with steam injected through line 31. The steam and recovered oil vapours are mixed with the cracked vapours and passed through a further separator 16 to a fractionator 18 from which fractions of gasoline boiling range are recovered through line 19 and cooler 20 to storage tank 21. The coke may be deflected by damper 37 into discharge line 42 or fed to grinding chamber 32 having grinding rolls 33 from which it passes to hopper 35 and is discharged by conveyer 38 or recycled to dispersion chamber 4 by conveyer 36 where it is dispersed by steam fed through line 22 and super-heater 23.

Title: Improvements in radio receivers
IPC: H03D1/22
Filed: 1963-04-04
Abstract: 1,031,216. Multiplex radio signalling; automic frequency control systems; telephone transmission systems. GENERAL ELECTRIC CO. April 4, 1963 [April 19, 1962], No. 13437/63. Addition to 815,601. Headings H3A, H4L and H4R. A multiplex system comprises means for transmitting a first information signal as a double sideband suppressed carrier signal, and means for transmitting a second information signal as an effective single sideband signal. In Fig. 1, the first information signal comprising a band of frequencies of width f m  passes through a low-pass filter 3 and amplitude modulates a carrier frequency f 0  in unit 4 the carrier frequency being suppressed. A second information signal in the form of D.C. pulses triggers a tone oscillator 6 of frequency f 0 Œf 1 , where f 1  lies outside the band f m . The second signal may, for example, be used for dialling purposes. The two signals from modulator 4 and oscillator 6 are added in unit 5 and sent by wire or radio to the receiver. At the receiver the received signal passes to two phase-shifting circuits 7 and 8 so that the inputs to detectors 9 and 10 are 90 degrees out of phase with each other. A second input to the detectors is provided by a local oscillator 15 which restores the carrier frequency f 0 . The outputs of the detectors pass through low-pass filters 16, 18 and amplifiers 17, 19 to a phase detector 21 which generates an error signal having a polarity and magnitude determined by the direction and magnitude of the phase difference between the local oscillator wave and the suppressed carrierwave. This signal passes through a filter 22 to correct the phase of the local oscillator. When the local oscillator is locked in phase to the carrier-wave the output of amplifier 17 is a faithful reproduction of the first information signal f m . Filter 16 is designed to cut-out frequency f 1 whilst filter 18 passes this frequency. The signal f 1  does not affect the phase detector 21, partly because it is cut-out by filter 16 and partly because it is in effect a single sideband modulation. The signal f 1  is recovered from amplifier 19 via an amplitude detector 20. In a modification, Fig. 2 (not shown), the tone oscillator 6 is arranged to transmit three digit information, the frequency f 0  + f 1  for one digit, frequency f 0  - f 1  for a second digit, and zero for the third digit. At the receiver, filters 16 and 18 each pass signals of frequency f 1 , and the frequency f 1  is rejected from the other modulation f m  by a notch filter. The outputs of amplifiers 17 and 19 pass through phase-shift circuits, similar to circuits 7 and 8, to a signal phase detector which produces a positive, negative, or zero output according to whether the transmitted second information signal is f 0 +f 1 , f 0  - f 1 , or zero.

[Class 38 (v).] In time switches operated by tappets on a day dial in which the tappets are automatically adjusted throughout the year by suitably shaped cams 13, 14 on a year wheel, the cams engage pins 15, 16 on rectilinearly guided racks 17, 18 which have toothed engagement with cog wheels carrying the two tappet arms 30 (only one shown). There are also two manually adjusted tappet arms and normally the arms are so arranged that if one arm switches the current on, the succeeding arm switches it off. If it is wished, however, to have only one " on " and " off " operation during the day, two arms may be moved into the same angular position so as to compensate each other, the automatically-adjustable arm carrying the other along with it. The year wheel is driven from the day dial by means of a fixed eccentric on the axis of the day disc, and a two-fingered pawl on the eccentric which rotates a ratchet wheel mounted in the day disc, one tooth a day, the ratchet wheel in turn engaging teeth on the year wheel.
