Abstract: 345,950. Pneumatic separating. GROVES, W. W., 30, Southampton Buildings, London.-(Falkiner, R. S. and Charley, W. G. ; 103, William Street, Melbourne, Australia.) Dec. 30, 1929, No. 39765. [Class 117.] In machines of the type described in Specifications 251,739, 284,683, 317,352, and 318,674, [all in Class 6 (iii), Harvesting appliances], in which the cane is cut into short lengths or trashed the trash is separated from the cut cane by repeatedly elevating and dropping the cut cane and trash through an air current. The chaffed cane is carried by an elevator 52 to the separating devices comprising a drum 53 mounted to rotate in brackets 54. The drum is provided on its interior with helically-arranged slats 76 that carry the cane and trash upwards and discharge it to be acted upon by a current of air drawn through the drum by a fan 71. The lighter trash is thus drawn through the drum and discharged at the rear of the machine. The heavier cane is gradually worked by the slats 76 to a discharge space 77 situated between the drum 53 and a similar drum 62 preferably arranged to rotate in the opposite direction. The discharge space is covered by a hood 91 that is only provided with openings to permit the passage of an endless bandconveyer which travels round a frame arranged on the machine and carries the cut cane to carts. The air sucked in through these openings removes the last traces of trash from the cut cane being carried out on the conveyer. The drum 62 is fitted with vanes 94 arranged to move any good cane which reaches that drum back to the discharge space 77.

Title: Process for preparing halogenated hydrocarbons
IPC: C07C17/281
Filed: 1946-06-14
Abstract: Halogenated hydrocarbons containing fluorine are prepared by treating a fluorinated hydrocarbon, containing not more than one hydrogen atom and one chlorine atom per two carbon atoms, at an elevated temperature of at least about 85 DEG  C. in the absence of water such that a different compound is produced having no less carbon atoms than the starting material.  The latter is preferably a fluorine-containing chloroethylene or perfluorobutadiene), in which case the heating is advantageously performed in the presence of a polymerization catalyst or an oxygen or peroxide promoter. The temperature employed is preferably at least 100 DEG  C. and may correspond to pyrolysis conditions.  The products are principally dimers and trimers, but in some cases C2 starting materials yield C3 products, whilst pyrolysis conditions may result predominantly in the formation of cyclic compounds with the same number of carbon atoms as or a higher number than in the starting material.  The products may be subjected to the following further reactions: (a) dehalogenation (e.g. CF2 = CF-CFClCF2Cl with zinc in alcohol yields CF2 = CF-CF = CF2); (b) replacement of allylic chlorine by a functional group, e.g. one derived from an alkali metal salt (e.g. sodium cyanide) or from ammonia or an amine.  Apparatus suitable for the dechlorination process is described with the aid of a drawing.ALSO:Fluorinated olefines or diolefines, which may also contain not more than one hydrogen atom and one chlorine atom per two carbon atoms, are polymerized by heating them to at least about 85 DEG  C. in the absence of water and in the presence or absence of a polymerization catalyst or an oxygen or peroxide promoter.  The products may be in part resins, which may be plasticized by the additions of products of low or intermediate degrees of polymerization, and may be used as insulating covering for wires or for the manufacture of moulded articles.  Preferred starting materials are those free from hydrogen, especially perfluorobutadiene and trifluorochloroethylene.

Abstract: 1,160,172. Pulse circuits. INTERNATIONAL STANDARD ELECTRIC CORP. 7 Sept., 1967, No. 40948/67. Heading H3T. Pulses produced at a remote control station by opening and closing contacts are fed to a receiver in which they are differentiated to provide pulses at the opening and closing of the contacts and these are fed to difference inputs of an OR gate followed by a low pass filter which so flattens input pulses that short and steep interfering pulses do not affect the controlled equipment. Pulses produced by opening and closing contacts 1-R of a telecontrol system are differentiated by C 1 -C n  and the circuit resistance. Negative and positive pulses respectively pass through diode D11 and through a diode D12 followed by an inverter transistor T to the two diodes Da, Db of an OR gate. The gate includes a low pass filter capacitor CT which so reduces the length of narrow interfering pulses (a, Fig. 2, not shown) that they are insufficient to operate a succeeding Schmitt type threshold detector controlling a start circuit.

Heading H3T. [Also in Division H2] A permanent magnet synchronous motor operating from a D.C. supply has field coils which form part of a switching circuit and are coupled to a control circuit in the form of a tuned buffer circuit which provides a variable phase and frequency output and allows for easy synchronizing of the motor to an external signal. The motor 1 comprises a permanent magnet rotor 4 co-operating with centre-tapped field windings 8, 8<SP>1</SP> which are supplied from the transistor oscillator circuit including transistors 6, 61 supplied from battery 9 and feedback windings 7, 7<SP>1</SP>. The feedback windings are connected either directly or in series with secondary windings 12, 12<SP>1</SP> of coupling transformer 11, by means of switches 10, 10<SP>1</SP> depending on the type of operation required. This motor forms the subject of the invention of Specification 1,068,843. The speed of the motor may be synchronized with a signal which is applied through the control circuit to primary 13, 13<SP>1</SP> of the coupling transformer. A feedback signal corresponding to the rotor speed is also applied to the input of the control circuit. As shown the control circuit comprises a buffer oscillator 3 and amplifier 14 and is supplied from a stable signal oscillator 2. The provision of feedback signal A causes the phase and frequency of the output of oscillator 3, whose centre frequency is approximately equal to that of oscillator 2, to vary in accordance with the motor rotor speed and phase and thereby prevent hunting of rotor 4. In a modification, Fig. 5 (not shown) a twin-tee bandpass filter circuit is used to replace the buffer oscillator described previously, the remaining parts of the circuit being substantially the same. In an alternative arrangement, Fig. 3 (not shown) a twin-tee buffer oscillator is used to control the operation of the switching transistors for supplying current to the motor field windings. The pick-up coils supplying a feedback signal to the input of the oscillator, thus eliminating the oscillatory circuit formed at the motor. In this application it is stated that controllable rectifiers may be used.
