Abstract: 1,226,713. Radio receiving apparatus. I. KOCUBEJ. 18 July, 1969, No. 36204/69. Heading H3Q. In a combined car radio and tape recorder having a housing 10 with an opening 12 in front closed by a shutter 15 embodying a tuning scale 16, the shutter 15 is adapted to be deflected by tape cassette insertion (Fig. 1). When the tape cassette 13 is inserted (Fig. 1) actuating lever 47 is deflected upwards and actuates slide bar 39 of a change-over switch 38 via spindle 46, radial arm 45 and spring 44 so as to change switch 38 to the tape recorder position. On removal of the tape cassette 13 (Fig. 2, not shown) the lever 47 swings down and slide bar 39 is moved by spring 43 to operate switch 38 to its forward position for radio reception. A tuning knob 30 is geared to a spindle 31 which drives the tuning capacitor 29 via a cord 32. Also the tuning knob 30 is coupled to a pointer, e.g. by means of a worm arranged concentrically with the hinge axis of the shutter 15 so as to move the pointer along the dial 16. The housing 10 includes, below the space 14 for tape cassette insertion, printed circuit radio receiver and amplifier elements (18, 17, Fig. 3, not shown), and a tape drive wheel (25) coupled via a belt (26) with an output wheel (24) of the tape electric drive motor 22. Also within the housing 10 is a tape drive spindle 27 and record and replay head 28. In the tape recorder position of switch 38 (Fig. 1) the tape recorder can record sound being received and played by the radio, can record by a microphone or can replay a tape. The radio may be a two channel stereophonic type and the recorder can use one channel while the other channel is used for the radio. For recording by microphone or replaying a tape the other channel may be switched off or the radio detuned. Input transistors 58 may be mounted on the rear of the housing.

Abstract: 1,229,068. Digital transmission systems. NETHERLANDS POSTAL & TELECOMMUNICATION SERVICE, DIRECTOR GENERAL OF. 29 April, 1969 [10 May, 1968], No. 21806/69. Heading H4P. In a digital transmission system in which errors are corrected by requested repetition, reduction in the useful character rate on the transmission channel owing to the repetitions is at least partially compensated by making the actual rate on the channel higher than the character rate of the overall system. As characters are received from the channel at a greater rate than they are delivered to the output printer a buffer store precedes the printer. To prevent the buffer from overflowing idle signals are transmitted when necessary.  Transmitter.-5-bit characters read from a store are passed to a radio transmission channel at a character rate V#a. Each time a character is read out a counter is incremented. The counter is decremented by clock pulses at a rate equal to the rate Va at which characters are read from the receiver buffer to the printer. The instantaneous count consequently represents the number of characters in the receiver buffer at the corresponding point in the received sequence of characters. If the count reaches 5 the buffer will be full. To prevent overflow, read out from the store is stopped while an idle signal is transmitted. Receiver.-The received signals, except idle signals, are passed to the first stage of a shift register buffer which has 5 stages, each of which can store one character. A counter is incremented at rate V#a and decremented at rate Va, as at the transmitter, and causes the appropriate stage of the buffer to be read to a shift register which passes serial-bit characters at rate Va to the printer. In the event of an isolated 4-character repetition cycle the printer will receive an uninterrupted flow of characters, characters being supplied from the buffer during the 4-character period in which input to the buffer is prevented.

Abstract: 1325851 Rolling mills ALCAN RESEARCH & DEVELOPMENT Ltd 10 Jan 1972 [13 Jan 1971] 1767/71 Heading B3M [Also in Division C5] A method of operating an aluminium rolling mill involves charging the lubrication system of the mill with an oil in water emulsion, periodically checking the average particle size of the oil phase, and if necessary increasing or decreasing the particle size to maintain it within an optimum range. The oil phase of the emulsion includes a hydrocarbon oil base, a substantial proportion of a free fatty acid and an amino-soap. The particle size is increased by adding multi valent metallic ions (e.g. aluminium sulphate) to the aqueous phase, and is decreased by adding an alkoli metal soap (or a material which will generate such a soap by reaction free fatty acid), such as sodium hydroxide. By keeping the particle size constant, the surface finish of the rolled products does not deteriate after a few days. The particle size, which can be determined by measuring the metallic ion content, is sufficiently small that the emulsion can be filtered to remove metallic particles with effecting the particles of the oil phase. An example of a suitable lubricant is an aqueous emulsion containing 6% by weight of an oil phase, the phase comprising about 12% oleic acid, and 5% triethanolamine which forms an amine soap emulsifier. An extreme pressure lubricant, such as tricresyl phosphate, and a coupling agent, e.g. diethylene glycol, may also be used.

Abstract: 1330351 Sonar apparatus BRITISH AIRCRAFT CORP Ltd 15 Sept 1971 [15 Sept 1970] 44073/70 Heading H4D Sonar pulses are transmitted by energizing from a single source a line of transducers with a phase difference between successive transducers to produce a narrow beam pulse wherein the phase differences are varied for each pulse to swing the beam across a wider sector. In a ship mounted sonar system the transducer array comprises nine horizontal strips containing sixtyfour transducers. In each strip the transducers are energized at a prf which is varied to swing the beam in azimuth and the relative timing of the energization of each strip moves the beam in elevation. Unit 10 receives inputs at the transmitter prf (1 Hz) and the beam stepping frequency (5 KHz) and produces an azimuth demand signal at the transmitter prf which comprises sixty six-bit digital words each word corresponding to a particular azimuth appearing at the beam stepping frequency. A left/right command signal is also produced which commands the transducers to be energized in the opposite direction after one-half of the required sector has been swept out-thus enabling a smaller range of phase differences to be utilized. In the unit 12 a counter is started at a time selected by the required beam elevation and the counter output is compared with the instantaneous azimuth demand. At equality a comparator produces a pulse which resets the counter and advances a six-bit counter. Thus the six-bit counter is clocked at a frequency dependent on the azimuth demand. The six-bit counter output is passed to a gate control which specifies the direction in which the transducers are to be energized. The gate control output is passed to the transducer drive circuits which decode the output and fire each transducer in turn, the repetition rate being dependent on the azimuth demand. As the unit 10 changes the azimuth demand, the rate and direction of energizing the transducers is varied to sweep the beam across the required sector.
