Title: A foldable floor panel for motor vehicles
IPC: B60N2/30
Filed: 1961-08-15
Abstract: 923,198. Vehicle seat backs. FORD MOTOR CO. Ltd. Aug. 15, 1961 [Sept. 14, 1960], No. 29382/61. Class 103(2). A vehicle floor panel in a station wagon is comprised of sections 12, 18, Figs. 1 and 2, hinged together at 17, Fig. 3, the section 12 being hinged through brackets 13 to the vehicle body so as to be raisable from the position shown in Fig. 2 into a substantially upright position, Figs. 1 and 3, in which the sections 12, 18 are folded together to form a seat back for a seat cushion 11, a support member 25 being pivotally connected at 26, Fig. 5, to the free end of the section 18, so as to provide vertical support for that end when the panel is extended as shown in Fig. 2, and linkage means 31 to 36 are connected between the support member 25 and the section 18 and arranged to fold the support member against the section 18 as it is folded and erected to form the seat back. The section 12 is provided with pivotal legs 15 to support it when the panel is extended, the panel sections being counterbalanced by springs 19. Referring to Fig. 5, the linkage means comprise a link 31 parallel to the section 18 and pivoted at 33 to the support 25, the link also being pivoted at 36 to a link 34 pivoted at 35 to the section 18, and also pivoted at its end, at 32, to a spring steel link 28, pivoted at 29 to the section 12. The pivots 26, 33, 35 and 36 form a parallelogram and as the section 18 in raised in Fig. 5, the link 31 causes the support to fold against the section 18 until finally the parts assume the positions shown in Fig. 3. As the sections are extended to form the floor panel, the support is caused to pivot away from the section 18. The section 18 has a catch 21 to coact with the section 12 when the sections are folded and serving as the seat back. The section 18 also has a bracket 22 thereon to coact with a latch mechanism (not shown) on the vehicle wheel housing 23, Fig. 1, to lock the seat back in its upright position.

Title: Adaptive equalisers anaesthetists ventilator
IPC: H04B3/14
Filed: 1972-06-23
Abstract: 1432766 Transversal equalizers DEFENCE SECRETARY OF STATE FOR 12 July 1973 [23 June 1972] 29444/72 Heading H4R In an adaptive transversal equalizer for delta-modulated signals, the correlation and weighting of the derived error signal with digital delay line taps is performed in analogue fashion in coincidence gates 24, 23 or their equivalents, such as Exclusive-Or gates or modulo-two address. The error signal is derived from the difference 16 between the quantized 14 and unquantized outputs of an adder 20 receiving the outputs from correlation, integration and weighting circuits M1, M2 associated with shift-register delay lines SR1, SR2. The analogue error signal is converted 21 to duty-cycle format (i.e. pulse-width modulated) before analogue multiplication with the delay line tap signals in the gates 24 and 23. The analogue to duty-cycle converters (Fig. 2, not shown) each consist of a sawtooth generator (4a) feeding a threshold circuit (4b) in synchronism (8) with the delta-modulator (3), the input analogue signal (2) either modifying the threshold level or being added to the sawtooth prior to threshold detection to produce duration modulated pulses. The integrators (Fig. 7, not shown) each consist of an R-C smoothing circuit (31, 32) voltage follower amplifier (33) controllable bridge-rectifier (34) and integrating op-amp (36) in series, the duty cycle of the bridgerectifier being controlled to be high when errors are large to give high gain and short time constant in the loop containing the integrator, and thereby accelerate convergence.

Abstract: 705,731. Automatic frequency and phase control systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 17, 1951 [Dec. 20, 1950], No. 29475/51. Class 38 (4) The valve 1 of a blocking oscillator, or one of the valves of a multi-vibrator or other relaxation oscillator, comprises at least five electrodes of which the cathode 2, inner control grid 3, and screen 4 are inter-connected to constitute the blocking oscillator ; synchronizing pulses A being applied to the outer control grid 5 to yield at the anode 6 a series of pulses whose area varies according to the phase relation between the sync pulses and the relaxation pulses generated by the blocking oscillator. The anode voltage is smoothed by a condenser connected across the anode resistor 8, and is applied to the inner control grid 3 to adjust the frequency of the blocking oscillator and so to obtain a desired phase relation between the sync pulses and the relaxation pulses. The sync voltage A may be of saw-tooth or sinusoidal form. When a multivibrator is used as the relaxation oscillator, Fig. 2 (not shown) the second valve may be a triode reciprocally coupled to the electrodes 3, 4 of the valve 1, the resistance-condenser couplings being arranged to render the valve 1 conductive for a shorter time than the triode. The synchronizing voltage is fed to the outer control grid 5 of the valve 1, and the correcting voltage is fed from the anode 6 to the inner control grid 3 as in Fig. 1.
