Patent GB-489954-A (GB)
Title: Improved manufacture of rubber chloride and like compositions
IPC: C08C19/14
Filed: 1937-02-05
Abstract: A solution of rubber in carbon tetrachloride or other halogenated solvent is boiled until its viscosity is permanently lowered, and chlorine is passed in while maintaining the solution at boiling point under reflux.  The rubber may be milled to plasticity before boiling. The time of boiling is generally not less than six hours; longer than 48 hours is not necessary.  In the first stages of the boiling, solvent may be permitted to escape to remove any moisture. Chlorination may be facilitated by the use of catalysts and ultra-violet rays.  When chlorination is complete, boiling is continued for a time to remove hydrochloric acid and free chlorine. Lime or the like is now added to neutralize any remaining traces of acid, and the clear solution is decanted from precipitated impurities.  The chlorinated rubber may be removed from the solvent by precipitation in boiling water, alcohol, or petroleum. Specification 328,818, [Class 70], is referred to.

Patent GB-470010-A (GB)
Title: Process of generating saw-tooth electric vibrations or triangular wave-forms
IPC: H03K4/00
Filed: 1936-02-06
Abstract: 470,010. Valve generating circuits. MICHAELIS, E. (Kinne, E.) Feb. 6, 1936, No. 3624. [Class 40 (v)] Oscillations of saw-tooth or triangular waveform are produced by a back-coupled valve circuit tuned to the desired frequency by a condenser and with the back-coupling effected by an iron-cored transformer. A stepped wave-form is produced by a circuit of the super-regenerative type. As shown in Fig. 5, the grid circuit of a valve R is tuned by a condenser C1, and a coil L2 connected to the valve anode is coupled to the grid coil L1. The oscillations are taken off across a resistance W2, or a tuned circuit, in the anode supply circuit. For producing saw-tooth oscillations, the core of the coils L1, L2 is solid and may be of nickel-iron alloy or of steel. If a laminated or divided core is used, e.g. alternate laminae of chemically-pure iron, and steel stampings, a triangular wave-form results. The coils may also carry a direct current. The condenser C1 may be constructed so that its plates resonate mechanically at the desired frequency or at a multiple thereof. Fig. 6 shows a superregenerative circuit in which, in addition to the back-coupling L3, L4, tuned to the desired frequency, a second back-coupling is afforded at a higher frequency by a circuit L5, L6, C6, the coil being centre-tapped to the valve cathode. This introduces steps in the waveform at the higher frequency of the circuit L5, L6, C6. The Specification states the dimensions of the various elements for operating at line or frame frequencies in television.

[Also in Divisions H3 and H4] In a modification of the circuit arrangement including a bulk effect semi-conductor device 616, 716 as claimed in the parent Specification, an antenna 618 (Fig. 1) is coupled to the device 616, to emit radiation of frequency fLSA and to receive reflected radiation Doppler shifted in frequency by a frequency fa or a sound responsive means such as a diaphragm 726 (Fig. 2) is arranged to vary the Q of the resonant circuit of the circuit arrangement. As shown in Fig. 1, the reflected radiation fLSAŒfa is mixed with fLSA produced by the bulk effect diode oscillator so as to obtain fa at the output 613 which may be a frequency meter calibrated to indicate the velocity of the target. Alternatively, the output may feed a speaker 613<SP>1</SP> to give an audible output and may be used for a burglar alarm. In an alternative embodiment (Fig. 2), a microphone is formed by a diaphragm 726 which is attached to a conductive plunger 725. The plunger 725 vibrates with the diaphragm to modulate the resistive loading of the cavity 715. This modulates the quality factor Q of the resonator so as to provide an amplitude modulated output via a transformer 714 to a load 713. A waveguide may be used for transmitting the output to a load and this filters out low frequency components in the output. An equivalent circuit of Fig. 2 is disclosed (Fig. 3, not shown).

Title: Improvements in or relating to arrangements for stopping rapidly moving record carriers
IPC: G11B15/48
Filed: 1961-02-03
Abstract: 895,302. Feeding magnetic tapes. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 3, 1961 [Feb. 6, 1960], No. 4101/61. Drawings to Specification. Class 40 (2). [Also in Group XIX] A rapidly-moving record tape is decelerated when a stop signal issues, the number of certain marks passing the reading head thereafter until the tape stops being counted, the total being used to control reversal of the tape at slow speed until the tape is in the appropriate position to begin sensing of a selected group of data. Deceleration may be initiated by a stop character on the tape or by an external signal, and while deceleration is going on either the number of characters or the number of sprocket-holes passing the sensing station is counted. The counter is then complemented and the tape reversed at slow speed, the sensing of each character or sprocket hole, as the case may be, causing the counter to be incremented until a comparator determines that one more pulse would set the counter to zero. The tape is then stopped and is in a position to begin sensing the data following the stop mark. Two counters may be used, one recording the forward count and the other the reverse count, the tape being stopped when a predetermined difference in their counts is reached. The sprocket holes may be sensed capacitively or photo-electrically. If capacitively, the condenser sensing the holes is rectangular in shape, rather longer than the diameter of a hole. It is stated that although the invention is described in connection with punched paper tape, it may also be applied to magnetic tape and that marks on the feed rollers may be counted to determine deceleration distance.
