Abstract: 1289306 Locks WILMOT-BREEDEN Ltd 2 Dec 1969 [3 Dec 1968] 57393/68 Heading E2A A vehicle bonnet latch comprises a release member 6 to which is attached a key operated lock assembly 1 which is slidable to release the latch, turning the key between unlocking and looking positions moves a blocking member 4 of the assembly from an inoperative to an operative position which, when the latch is in use, fouls a fixed part of the vehicle body structure and thus prevents sliding release movement of the lock assembly. The lock assembly 1 is mounted to be accessible through an aperture in a radiator grille and is depressed to release the latch by the member 6 pivotally attached to the body 2 of the lock. An inner cylinder 2 is rotated by the key to move the blocking member 4 projecting from one end of the cylinder to a position where it abuts part of the vehicle structure and so prevents inward movement of the body 2 and hence release of the latch. A plastics shield 18 pivotally mounted on the body is spring urged to cover the end of the body and is pivoted to uncover the keyhole for insertion of the key.

Abstract: 1289364 Can openers AlCHIDENKIKOSAKUSHO KK 31 Dec 1969 [23 April -1969] 63448/69 Heading B8D A detachable hand lever or arm 23 carrying a cutter wheel 40 is pivotally-mounted on the body frame 10 of a can opener by a shaft 24, which is releasably-retained in a body frame bearing 26 by a spring-biased holding mechanism engaging a groove 29 in the shaft. The mechanism comprises a plate 30 having an aperture 32, the edge of which is urged into engagement with the groove by a spring 34 once the coned end 27 of the shaft has been pressed through the aperture. Depression of a button 33 urges the plate downwardly out of engagement with the groove and permits a spring 37 to shift the shaft axially outwards. The arm together with the shaft and cutting wheel may then be removed for cleaning of the wheel. The body frame mounts an electric motor M driving a traction wheel 18. The arm mounts a magnet 46 and is adapted to operate a motor-energizing button 50 when lowered to its operative position. In another embodiment, Figs. 6 and 7 (not shown), the holding mechanism comprises a curved spring strip 30 having an intermediate portion whose engagement with the shaft groove may be released by raising a free end portion of the strip to facilitate removal of the shaft and arm. In a similar embodiment, Figs. 8 and 9, the groove is provided in only a part of the shaft circumference so that rotation of the shaft on pivoting the arm 23 upwards causes the disengagement of the strip from the groove.

Abstract: 1290537 Electro-medical apparatus F HOFFMANN-LA ROCHE & Co AG 2 Oct 1969 [2 Oct 1968] 48382/69 Heading GiN In apparatus for detecting a respiratory distress condition, a signal representative of heart-beat activity is applied to a sensor 32 which produces a signal when the heart-beat falls below a predetermined frequency level, and a signal representative of respiratory activity is applied to a sensor 43 which produces a signal when a respiratory arrest exceeds a predetermined time interval, an AND gate 33 being responsive to coincidence of the signals from the sensors to actuate an alarm 18. As shown, a heart-beat signal is applied, via a transducer, to electrodes 21, amplifier 25, filter 26 and pulse-shaper 27 to produce identical pulses at a frequency corresponding to the heart-beat frequency, Fig. 3c (not shown). This pulse signal is integrated at 28, over a pre-selected period and the integrated signal, Fig. 3d (not shown), is applied to a meter 31, calibrated in beats per min., and to a level sensor 32 which produces an output pulse, Fig. 3e (not shown), when the integrated signal falls below a preset value, e.g. representative of 90 beats/min. A respiratory signal is applied, via a transducer to electrodes 34 energized by a high frequency source 35 to produce a high frequency carrier amplitude-modulated signal, Fig.3f (not shown), which is applied to amplifier 36, high pass filter 37, demodulator 38, zero-crossing detector 39 and pulse shaper 41 to produce identical pulses at the breathing frequency. The pulses are applied to a multivibrator 43 which produces an output if breathing stops for a period exceeding a pre-set time. The pulses from 41 may also be applied to an integrator 47, similar to integrator 28, the integrated signal being applied to a meter 49 and a sensor 51 whose output, when breathing rate is below a pre-set minimum, is applied to a delay circuit 54 and whose output, when the breathing rate is above the pre-set minimum, is applied to reset the delay circuit. If the delay circuit is not reset within a period set by the delay circuit, the alarm 18 is actuated via OR gate 45.

In Fig.2 the fan blades 2 are in the reverse thrust position in which air is being discharged through the forward air intake 8, air under pressure tapped from the engine compressor is discharged through openings 20 in the inner wall of the fan duct andthrough openings 24 in the outer wall of the fan duct, also through an opening 21 at the forward end of the fairing cone 9, whereby the fan air is urged towards the engine axis. In a second embodiment pivotally mounted flaps are provided at the inner surface of the fan duct which flaps are pivoted inwardly during the reverse thrust mode of operation whereby the fan air is again urged towards the engine axis. The object of the invention is to prevent the fan air from discharging laterally and possibly rearwardly from the duct during reverse thrust operation.

As described, a number of circular electromagnets 2 are loosely mounted on a shaft 3, each electromagnet having a coil 2a and a polepiece (the discs), the latter being attracted by the electromagnet immediately to its left. A double acting pneumatic or hydraulic ram 6 is operative to collapse and extend the device. The degree of travel of each electromagnet is limited by stops mounted on rods 4 the lengths of which are arranged according to a coded progression, e.g. binary. In operation the device is collapsed, the required electromagnets are energized in accordance with a digital input signal, and the device is then extended, the total extension being determined by the sum of the movements of the non-energized magnets. For heavy loads where the inertia of the load at the end of the extension might separate energized magnets a damper is provided. The damping device may be pneumatic. A brake may be provided to lock the device in its extended position. The ram 6 may be replaced by an electric solenoid, an electric or linear motor.

Abstract: 1347776 Analogue signal generators INTEGRATED PHOTOMATRIX Ltd 9 Oct 1972 [29 Oct 1971] 50396/71 Heading G4G Apparatus for converting a sequence of current pulses into a sequence of steady voltage levels comprises an integrator for integrating in turn each current pulse and a feedback circuit for simultaneously applying to the integrator a re-set signal proportional to the integral of the preceding pulse. The apparatus includes a normally-open gate 24 and normally-closed gates 26, 29 whose conditions are reversed for the duration of control pulses 3B from generator 31. Such control pulses occur at the start of every operative time cycle, each of which may or may not contain an input current pulse 3C. Assuming the preceding pulse to be zero, integrator 23 will invert and integrate input pulse 3C from zero level throughout the duration of cycle 1 to produce voltage signal 3D which is gated to a follow-and-hold circuit 25 during the portion of cycle 1 not occupied by the control pulse 3B. Circuit 25 thereupon stores the voltage signal 3E. At the start of cycle 2 gate 26 is opened to transfer the amplitude of signal 3E to a second follow-and-hold circuit 27. At the same time, a signal 3F having a charge proportional to the stored voltage 3E is transferred by the gate 29 to the input 22 of the integrator 23 where it is added to the next succeeding input pulse. If the next pulse is zero (as shown), the integrator is completely discharged, or if a pulse occurs, this is effectively integrated from zero level. The width of the control pulse is such as to allow the second follow-and-hold circuit 27 to attain the voltage stored in the first circuit 25 within the duration of the pulse. At the start of cycle 3, the circuit 27 acquires a voltage proportional to the integral of the next succeeding pulse (as shown, this is zero), and so forth. The output stage 28 provides amplication and filtering of transients. An output signal of changing levels is obtained (as shown, a positive level between two zero levels).
