Title: Motor vehicle suspension
Inventor: DREISZIGER JOSEF LASZLO
IPC: B60G3/24
Filed: 1962-12-12
Abstract: 987,778. Road vehicle spring suspension. FORD MOTOR CO. Ltd. Oct. 2, 1963 [Dec. 12, 1962], No. 46845/62. Heading B7D. In a motor vehicle suspension each rear wheel is rotatable on a hub 13, a transverse link 1 is pivotally connected about longitudinal axis to the hub 13 and to the vehicle, a combined shock absorber and spring unit 23 is connected rigidly to the hub 13 and resiliently to the vehicle, and a trailing link 43 is pivotally connected to the hub 13. For a driven wheel, as shown, the transverse link 1 consists of a drive shaft connected by universal joints 3, 5 to the output member of a differential (not shown) and to the spindle 7 of the wheel. The resilient connection of the unit 23 to the vehicle includes an annular rubber mass 34 permitting limited axial and pivotal movement of the unit. The pivotal connection of the trailing arm 43 to the hub 13 includes polyurethane bushes 5 permitting limited universal movement and is disposed on an axis parallel to a line between the universal joint 3 and the centre of a pivot 45 which connects the trailing arm to the vehicle and includes a rubber bush 47. The universal joint 3 may be adjusted longitudinally of the vehicle to provide desired steering characteristics, and the arrangement is such that upward deflection of the wheel imparts toe-in to the wheel and causes camber change so that the wheel assumes a vertical position when the vehicle is cornering with maximum roll.

Title: Sulphomethyl derivatives of polymxin
Inventor: WILKINSON SAMUEL
IPC: C07K7/62
Filed: 1962-12-13
Abstract: The invention relates to a salt of a sulphomethyl derivative of polymyxin B or E with a pharmaceutically acceptable cation, characterized in that the salt has a LD50 (intravenous in mice) value of between 100 mg./kg. and 250 mg./kg. and is soluble in water to give a solution of pH 7.3 to 8.0, which solution forms no precipitate if acidified to pH 5.0.  The salt is prepared by treating a water-soluble salt of polymyxin with formaldehyde at pH 6.6 to 6.8, and dissolving the precipitate formed thereby in the aqueous medium with 1.2 equivalents of a bisulphite at pH 6.4 to 6.7 and then ageing the solution, e.g. at 50-55 DEG  C. for 30 minutes, until the pH rises to 7.3 to 7.5 and a sample no longer forms a precipitate when acidified to pH 5.0 and then freeze-drying the solution. A 2N alkali metal hydrogen carbonate/carbonate buffer of pH 8.5 is used in the formaldehyde treatment step.  The sulphomethyl polymyxins have high antibacterial activity and negligible pain and local effects on injection.  They may be incorporated in pharmaceutical compositions.ALSO:A therapeutic preparation for oral, parenteral or topical administration comprises a carrier and a salt of a sulphomethyl derivative of polymyxin B or E (amino groups replaced by NH,CH2SO3) having a LD50 (intravenous in mice) value of between 100 mg./kg. and 250 mg./kg., which is soluble in water to give a solution of pH between 7.3 and 8.0 and which forms no precipitate if acidified to pH5.  The preparation may be a tablet, lozenge, ampoule, solution, oil-in-water emulsion or ointment.  Neomycin, hydrocortisone or zinc bacitracin may also be present.  Sprays or aerosols may be used for inhalation.

Abstract: 1,179,255. Teaching equipment; controlling tape recorders. W. H. SIMS (TROWBRIDGE) Ltd. 17 Dec., 1968 [23 Oct., 1967], No. 48106/67. Headings G5G and G5R. Teaching equipment comprises a control circuit 2 connected to a twin-track magnetic tape recorder 1 and responsive to marker signals recorded on one track, at the intervals between the stages of a lesson recorded on the other track, to stop tape movement until a switching circuit 7, 73 is manually operated by a teacher at a monitoring station, the students wearing headphones 76 connected to the audio output of the tape recorder. As shown, the marker signals pass through a low-pass filter 26 to a transistor amplifier, whose D.C. supply is derived from a tape recorder output 3, to render driver transistor 41 conducting. Relay contacts 61, 62 thereby close to operate a pause-relay in the recorder and a self-holding relay 7. Depression of switch 73 allows the tape to recommence. The marker signals may also be connected to a control circuit 100 operating a film strip-or automatic slide-projector 101, and the recorder may have a rewind facility (not detailed).
Patent GB-1135550-A (GB)
Title: Improvements in or relating to electric circuit arrangements providing earth leakage protection
IPC: H02H3/16
Filed: 1967-10-25
Abstract: 1,135,550. Protective arrangements. G. A. D. GORDON. 25 Oct., 1967, No. 48394/67. Addition to 1,105,027. Heading H2K. The earth leakage protective arrangement of the main patent is provided with a bi-stable transistor circuit TR2, TR3 which normally completes the circuit for the coil 10 of a reed relay to maintain its contacts 9 closed. These contacts complete the triggering circuits of controlled rectifiers SCR1, SCR2 which are in series with the primary winding of a transformer 2 supplying a load 3. In the event of earth leakage, current flowing in the reactive impedance 7, C1, is filtered and rectified and biases, an amplifying transistor TR1 to conduction. This causes the bi-stable circuit to change its state so that the transistor TR3 ceases to conduct and the relay 9, 10 releases so that the controlled rectifiers SCR 1, SCR2 cease to conduct and interrupt the primary circuit. Interruption and restoration of the supply is necessary to cause the bi-stable circuit to reset to its initial condition, a capacitor C5 ensuring that more current flows initially to the base of the transistor TR3 to render this transistor conductive.
Patent GB-1005020-A (GB)
Title: Improvements in or relating to radar display apparatus
IPC: G01S7/22
Filed: 1962-12-21
Abstract: 1,005,020. Radar display. ALBISWERK ZURICH A.G. Dec. 21, 1962 [Dec. 22, 1961], No. 48502/62. Heading H4D. In radar display apparatus displaying both echo signals and range marks, the demodulated echo signals are passed by a final amplifier to one control electrode of a cathode-ray tube through a first diode, and the range mark pulses are fed to said one control electrode through a second diode, the first and second diodes being connected to form an OR gate. Fixed range marks, Fig. 2A, are applied to input A, Fig. 1, where they are differentiated by capacitor C1 and resistor R1, and the resulting negative pulses passed via diode G1 to trigger a blocking oscillator arrangement, comprising a transistor H1 and feed-back pulse transformer T1. The thus-produced negative pulse of fixed duration is picked off by winding W (the positive oscillations being passed to ground by diode G2) and passed via gate diode G7 to output terminal D. Resistors R14 and R5, together with the potentials applied thereto, provide a potential of + 12 volts at terminal D when the gate diodes are not passing any signal. A movable range mark, Fig. 2B, applied to input B, similarly produces a negative pulse at terminal D. At the output terminal D the fixed range pulses extend down to - 6 volts and the movable pulse extends down to - 10 volts. Demodulated pulse echo signals, Fig. 2c, are applied to input C for application at a bias voltage of - 28 volts to the base of transistor H3, via a biasing Zener diode Z1. Capacitors C4 and C5 provide increased gain with frequency, such that the pulse echo signals are amplified more than the extended clutter signals. The amplification of the transistor H3 is adjustable by means of potentiometer R11 whilst potentiometer R12 is adjusted such that with no echo signal present the potential of the collector of transistor H3 is +10 v., representing the black level. Output terminal 10 is thus normally at a potential of 10 volts. Diode G10 and Zener-diode Z2, with- 12 volts supply resistor R13, limit the negative swing of the output to - 18 volts to prevent overloading the C.R.T. The combined output signal at terminal D is shown at Fig. 2D.
