Abstract: 1,232,236. Hydraulic shock absorbers. ARMSTRONG PATENTS CO. Ltd. 25 May, 1968, No. 25098/68. Heading F2S. In a tube-within-a-tube hydraulic pistoncylinder shock absorber of the kind in which the direction of flow between the inner (cylinder) and outer (reservoir) tubes is the same for both directions of piston movement, the one-way circulating flow is controlled by non-return valves 44, 52 in the piston 22 and cylinder end 46 respectively, and damping is achieved by causing the fluid to pass through a passage 58 located in the outer tube. Flow through this passage is restricted by a damping valve 62. In addition to the non-return flow-control valves 44, 52 and the damping valve 62, there are two safety valves 54, 56 which act in the opposite sense to the flow control valves 44, 52 and bypass the latter if the piston is abruptly loaded.

Abstract: 1,251,117. Dividing circuits. INTERNATIONAL BUSINESS MACHINES CORP. 3 Oct., 1969 [18 Oct., 1968], No. 48702/69. Heading G4G. A circuit suitable for use with a photosensitive device for character or mark reading systems, providing amplified contrast signals indicative of the presence or absence of a character or mark, includes a non-linear device for connection to the photo-sensitive device, which non-linear device is also connected to one input of differential voltage amplifier, the other amplifier input being connected to a negative feedback circuit which includes a voltage comparator feeding a peak voltage storage device, whereby the steady state amplifier output is independent of the input current, whereas the transient amplifier output upon a change of input current from a first to a second value is a function of the ratio of those two current values. As shown, the currentgenerating light-sensitive device 10, utilized to detect the presence or absence of a mark on a document is connected to one input of an amplifier 20, and to both the base and one N-type region of an NPN transistor, the other N-type region of which is earthed; the latter arrangement provides an approximately logarithmic characteristic, whereby a voltage signal compressed with respect to the current signal from device 10 is applied to the amplifier input 21. In the absence of a mark on the document, device 10 will generate maximum current, and the output of amplifier 20 will initially be a positive voltage which, applied to the comparator formed by the two transistors 44 and 45, causes transistor 44 to conduct more current than transistor 45, whereby the collector voltage of transistor 45 rises, increasing the current through transistor 65 and charging the capacitor 27, the emitter voltage of transistor 65 being fed back to amplifier input 30 to produce a substantially zero output voltage at terminal 24. When the presence of a mark on the document reduces the light input to device 10, the output of amplifier 20 goes negative, causing transistor 45 to conduct more current than transistor 44, and biasing the transistor 65 to off. Thereafter, discharge of the capacitor 27 maintains the feedback signal to the amplifier 20 substantially constant for a sufficient length of time to permit the amplifier output at terminal 24 to exhibit a pulse resulting from and indicative of the change in light input to device 10 associated with the change from a mark-free document surface to the presence of a mark. An alternative circuit is disclosed (Fig. 3, not shown) which provides output pulses of the opposite sense.

A spring 14 biasses the element 13 2  into engagement with a further toothed element 13, which is carried by a gear wheel 9. The shaft passes freely through the element 13 1  and the gear wheel 9. The wheel is driven, through further gears by the motor 5. The teeth on the elements 13 1  and 13 2  are shallow and have inclined faces so that at a given mix viscosity the elements slip relative to each other. The two compartments may contain different mixes.
