Patent GB-1135173-A (GB)
Title: Improvements in automatic telephone call sending devices
Inventor: BUCKLEY NORMAN IAN
IPC: H04M1/27
Filed: 1966-03-23
Abstract: 1,135,173. Automatic exchange systems, transistor circuits. SHORROCK DEVELOPMENTS Ltd. 17 March, 1967 [23 March, 1966], No. 12738/66. Headings H3T and H4K. An alarm message sender adapted when triggered to call a plurality of subscribers in succession has a magnetic tape on which is recorded a plurality of dialling codes and messages separated by end of dialling code, end of message and closing down signals. As shown the tape is in the form of a closed loop MT and carries a series of messages, each comprising a series of short impulses spaced in accordance with dial pulses of a required subscriber, an end of dial pulse signal, a verbal message and an end of message signal. The last message is followed by a sign off signal. Each of these signals is in the form of a conductive strip placed at a corresponding transverse location of the tape so as to bridge a corresponding pair of contacts or transparent regions detected by photo-electric means. Tripping of the alarm energizes a relay (not shown) completing a circuit between terminals 11 and 12. A relay A/6 is energized from battery BB closing contacts A1 to A6 thus connecting the apparatus to a telephone line 8, 9, 10 and starting the tape drive motor. Pulses detected by the reading head P are amplified at TR1, TR2 and used to trigger a transistor TR3 set to a threshold determined by the setting of a resistor R10. The trigger pulses are fed via a diode D1 to a mono-stable pulse lengthening circuit TR4, TR5 and TR6 switching transistor TR4 to conduction and transistors TR5 and TR6 off for a period determined by the setting of a resistor R19 for each pulse. Transistor TR4 when conducting energizes a relay B/1, opening its contact B1 in the telephone line to simulate dialling. At the end of the dialling pulses the first conductive strips bridge contacts K1 energising relay XC/4 operating its contacts XC1 to XC3, contact XC1 removes a short circuit from the secondary of a transformer T1. Contact XC2 removes a suppressor resistor R31 from across the telephone bell, and contact XC3 disables the trigger circuit. The spoken message is now transmitted to line via amplifying transistors TR7 and TR8 and transformer T1. At the end of the spoken message a conductive strip bridges contacts K2 energizing a relay E/2 operating its contacts E1 and E2. Contact E2 releases relay A/6 but maintains the charge on a capacitor C14 while contact E1 closes energizing a relay in a circuit (Fig. 2) not shown. This circuit includes a timing circuit comprising a capacitor which charges up until it breaks down a Zener diode the output of which, after transistor amplification, energizes a relay which again bridges the contacts 11 and 12 and effects the transmission of the next message recorded on the tape. After the last message has been transmitted a third magnetic strip bridges a pair of contacts disabling the timing circuit and releasing the apparatus. Valves may be used instead of transistors and a clockwork delay may replace the timing circuit.

Title: Locking means to prevent unauthorized use of cycles and motor cycles
IPC: B62H5/16
Filed: 1935-04-30
Abstract: 450,897. Locking cycle wheels. MURRAY, J., 8, Kew Road, Formby, Lancashire. April 30, 1935, No. 12825. [Class 79 (iii)] To prevent unauthorized use, one of the wheels of a motor or other cycle is adapted to be locked by means of a T-shaped element D radially slidable in a squared centre part of the bearing spindle A and normally withdrawn within the wheel hub J which is surrounded by an outer casing L. A rocking lever E, mounted in a slot in the spindle and actuated through cables F by a control lever M, is adapted to raise the element D so that the head I thereof bears against the inside of the rotating hub J until it is able to emerge through an opening Q therein, the control lever at the same time temporarily applying the wheel brake. The hub is slotted for nine-tenths of its circumference to the width of the stem of the element D so that rotation may continue to enable the head I, which is serrated on its under-surface, to be brought down, by return movement of the control lever M, into engagement with serrations J<1> formed on the outer surface of the hub, springs K attached to the inner surface of the casing L assisting the action. To facilitate re-housing of the locking element in the hub, the cycle wheel may be marked in the manner of a clock face, so that the position of the wheel at which the head I will be above the opening Q in the hub may be noted. A spot light is provided for night use.

Title: Improvements in or relating to aerial systems
Inventor: LAWSON WILLIAM DONALD
IPC: H01Q21/24
Filed: 1948-05-10
Abstract: 653,018. Aerials. MINISTER OF SUPPLY. May 10, 1948, No. 12840. [Class 40 (vii)] An aerial system with a polar diagram similar to that of a #/2 dipole in which the radiation emitted in the median plane is circularly polarized comprises a coaxial feeder with a flange 3 extending from the end of the outer conductor 2, the inner conductor 1 extending #/4 beyond the flange and a pair of diametrically opposite axial slots 4 and 5 of length #/4 being formed in the outer conductor, the slots 4 and 5 being continuations of radial slots 6 and 7 also of length #/4 formed in the flange. The slots 4, 5, 6 and. 7 are energized by probes 9 which extend radially inwards from the end of the outer conductor and are covered by a cylindrical dielectric block 8 with a radial dimension d given by d(##-1) = #/4, where # is the dielectric constant. The unipole 1 in conjunction with the flange 3 has a polar diagram similar to that of a #/2 dipole with the electric vector parallel to the unipole and the resultant radiation from the slots 4 and 5 has a similar polar diagram with the electric vector perpendicular to the unipole and since the dielectric mass 8 retards the phase of the radiation from the slots by 90 degrees, the resultant radiation from the unipole and the slots will be circularly polarized. Alternatively the outer surface of the dielectric block might be part spherical and the block may be associated with the unipole instead of the slots. The aerial is stated to be of use for installation on craft subject to erratic movements, e.g. balloons.

Title: Improved processes for making magnesium hydroxide
IPC: C01F5/20
Filed: 1933-05-03
Abstract: Magnesium hydroxide is obtained in readily filterable condition and in good yield by treating a solution of a magnesium salt such as the sulphate or chloride with a large excess of ammonia, say three times the quantity theoretically necessary, which is preferably added in the gaseous form.  Excess ammonia is recovered from the mother liquor, which may then be concentrated to obtain the ammonium salt remaining in solution.  A light form of hydroxide may be obtained by treating a solution containing at least 8 per cent of MgS04 with ammonia gas in an amount say 3.23 times that theoretically necessary; whilst a heavier, crystalline form may be produced by adding a solution containing 16 per cent of Mg S04 gradually and with agitation to an equal volume of water, whilst slowly introducing ammonia gas in an amount double the theoretical quantity, a further quantity of ammonia being then added more quickly.  The heavy form of hydroxide may be used in the preparation of fertilisers.
