Title: Improvements relating to aircraft seat harnesses
IPC: B60R22/46
Filed: 1963-02-27
Abstract: 1,012,354. Safety harness. J. MARTIN. Feb. 7, 1964 [Feb. 27, 1963], No. 7934/63. Heading A3V. In a seat-harness arrangement one or more spring loaded reels carrying shoulderstraps coact with a manually operable ratchet mechanism to rotate the reel(s) in the winding direction to tighten the straps. As shown, shoulder straps 3 are wound on reels 2 integral with a shaft 1 loaded by a spring 8 to tend to wind in the straps. Secured to the shaft 1 is a ratchet wheel 11 engageable with and rotatable in the direction of winding in of the straps by a reciprocable pawl 18. The pawl is pivotally mounted on a piston 16 which is normally spring loaded to maintain the pawl out of engagement with the wheel 11 but is reciprocable by means of a cable and hand lever (not shown) against the action of spring 20 to allow the spring urged pawl 18 to engage the wheel 11 and step by step rotate it in the winding-in direction. Rotation of the wheel in the opposite direction is prevented by a control pawl 12 normally engaged with the wheel. To allow the wearer of the harness to reach forward the pawl 12 can be disengaged from the wheel by means of a hand lever and cable (not shown) connected to a shaft 13 on which the pawl is mounted. The pawl 12 also forms part of an inertia locking device, Fig. 4. An acceleration-sensitive spring toggle mechanism 14 and a weight 15 cause the shaft 13 to rotate and move the pawl 12 into engagement with the wheel 11.

Abstract: 726,656. Automatic control systems for cathode-ray oscillographs. METROPOLITANVICKERS ELECTRICAL CO., Ltd. April 4, 1952 [April 5, 1951], No. 7939/51. Class 38 (4). [Also in Group XXXVI] In a cathode-ray oscilloscope of the kind disclosed in Specification 713,842, [Group XXXVI], in which a generated waveform is displayed point-by-point, means are provided for automatically centralizing the display along the time base axis by maintaining the long-term average value of the time base deflecting voltage (or current) substantially constant. The time base deflecting voltage is applied via a potential divider R1, R2, R3 to a valve V1 which alternates between conduction and non-conduction, depending upon whether the X deflection is instantaneously to the left or the right of the centre of the screen. The output of V1 is integrated by a Miller integrator V2 which controls the deflection amplitude by varying the duration of the scan (see below). Large deviations are corrected by rapid charge or discharge of the integrator condenser C1 via diodes V9, V10. If the deflection voltage rises unduly the potential at A never exceeds earth potential, the normally conducting diode V3 blocks, condenser C2 discharges, valve V4 cuts off, valve V5 conducts, diode V9 conducts and charges C1 A fall in deflection voltage causes V6, V7, V8, V10 to operate similarly. The duration of the scan is determined by a variable delay circuit which adjusts the point at which the scan is terminated relative to the point at which it is initially triggered by a master pulse. This delay circuit is actuated in recurrent sweeps so as to plot successive points along the waveform in successive cycles, and the output of V2 also controls this delay circuit to maintain the average scan, over many cycles, constant. Specification 711,734, [Group XL (c)], also is referred to.
