A door latch operating handle assembly comprises a handle 7, a shaft 5 fast with the handle and capable of operative connection to a second handle 7a through an intermediate mortise latch 27, a housing 9 in which the shaft is mounted so as to be capable of both rotary movement for operating the latch and for longitudinal movement so as to be displaceable out of connection with the second handle, a spring 20 mounted in the housing to bias the shaft towards the position of engagement with the second handle and means for locating the shaft in its alternative longitudinal positions. In the construction shown the locating means comprises a V-shaped projection 18 at the end of the handle 7 which is engageable with either of a pair of V section recesses 16 and 17 formed in a bush 8 journalled in the housing 9, the groove 16 being of greater depth than the groove 17. Both of the handles 7 and 7a have bores of square cross-section and the shaft 5 has portions 23 and 24 of square cross-section in the vicinity of its two ends and another square section portion 25 intermediate the ends, the remainder of the shaft, except for a tapering end portion. being of circular section smaller in diameter than the width of the square section. The portion 23 is engageable with the bore 22 of the handle 7a in the position of the shaft defined by the engagement of the projection 18 with the recess 16 and is out of engagement with the bore 22 when the projection 18 is in the recess 17. Similarly the portion 25 of the shaft is engaged with a square section bore in a follower 26 of the latch when the portion. 23 is in engagement with the bore of the handle 7a and disengaged from the follower in the other position of the shaft. Both of the handles are provided with centering springs 15 (not shown) and 15a and plates 11, 11a which co-operate with the housing 9 and 9a to limit the rotary movement of the handle.

Abstract: 976,242. Counters. PLESSEY CO. Ltd. March 14,1961 [Dec. 31, 1959], No. 44363/59. Heading G4A. A bi-directional pulse counting device reverses its counting logic dependent upon gating circuits controlled by pulses derived from the pulses to be counted. A binary cascade counter, Fig. 2, comprises bi-stable circuits 1-4 which add or subtract in conventional manner provided the add or subtract lead 11 or 12 is marked when input pulses are applied to lead IC. Read-out is effected over leads 1A-4A. In Fig. 3 the add or subtract pulses are applied to leads 14, 13.

Abstract: 1,248,836. Antiskid braking systems. SHARP K.K., and AISIN SEIKI K.K. 11 Sept., 1969 [11 Sept., 1968 (2)], No. 44857/69. Heading F2F. An antiskid control device for a road vehicle braking system includes a signal generating circuit with a tachogenerator 1 in the form of a quadratic differentiation generating device providing a voltage proportional to the angular acceleration of the wheel, a stage II circuit consisting of a Schmidt circuit and a signal inverting circuit, a stage III circuit which is a charging and discharging circuit, a stage IV circuit which is a release signal circuit, a stage V circuit which is a release circuit including a solenoid 33 operating a brake release valve in response to a signal from stage IV and a stage VI circuit which is a release signal shortening circuit. When the wheels are braked slowly, the output signal due to retardation is small and insufficient to produce an output signal from the Schmidt circuit of stage II, but when the wheels are braked quickly the signal exceeds the preset level of the Schmidt circuit and an output signal therefrom causes a capacitor 19 in stage III to be charged through a diode 18, the potential of the said capacitor being applied to the base of a transistor 23 in stage IV to exceed the preset level of a Schmidt circuit in the stage and cause a brake release signal to be applied to the release circuit of stage V causing a transistor 32 to conduct and a large current to flow in the solenoid 33 to release the brakes. Acceleration produces a negative signal and as the charge on capacitor 19 becomes lower solenoid 33 becomes disabled and the brakes are re-applied. The rate of acceleration varies with the friction coefficient of the road surface and by means of the negative signal applied to stage VI the collector potential of transistor 39 increases until it causes a transistor 22 in stage III to conduct and shorten the discharge time of capacitor 19, thus shortening the brake release time in accordance with the road surface.

The switch comprises reed relays each operating six contacts A1-A6, B1-B6. A potentiometer R3 across the oscillator output terminals ensures that when the coupling member is such that coupling between C1 and C2 is at a maximum the voltage in coil C1 is cancelled to give a zero output to the level detector. Resistor R1 and potentiometer R2 similarly ensure the correct output level when the coupling between C2 and C3 is at a maximum and when the coupling member is midway between C1 and C3. The coupling member preferably comprises a soft iron armature slidable within a tube on which annular coils are mounted. Flat, semicircular or C shaped coils may be used or the coils may be located within the coupling member. The apparatus may be used in a coarse and fine positioning system by moving the coupling member until first equality occurs between the count in counter 23 and a coarse desired position and then until equality occurs between the input OP to the level detector and an output of oscillator 27 attenuated by a desired fine amount.
