A strip P of photo-conductively coated material is fed through cutting knives 5 which cut the strip into ticket lengths, which are fed past a corona charging device 13 by endless belts 11a, 11b. A synchronous motor 15 drives an original carrier 16 in the form of a transparent disc carrying first originals 17, Fig.5, relating to fixed items of information. Variable items are carried on a carrier 18 and carriers 30a and 30b. The selected items are exposed to Xenon lamps 20, 25 and 32 to produce a composite latent image on the ticket length P 1 . The required items of information are selected by opaque trigger marks 40 and start marks 41 detected photo-electrically which feeds pulses to a control circuit, Fig.7 (not shown), which controls a clutch in the ticket feed, the knives 5 and charging device 13. Latent images produced are developed by liquid developer in a container 67 above which is a supply plate  (79), Fig.8 (not shown), across which tickets carrying images are fed by rollers (70, 71); the plate 78 is supplied with developer by a roller 79. Photo-sensitive paper e.g. blue print paper may replace the photo-conductive material. In other embodiments, Fig. 9 (not shown), two carriers (16a and 95) are provided; Fig.10 (not shown), one carrier (16a), and a stationery plate (101a) carrying originals as well as pulsed needle electrodes (106) are provided.

Abstract: 1383639 Spectroscopic apparatus BECKMANRIIC Ltd 27 Jan 1972 [27 Oct 1970] 50975/70 Heading G1A In a infrared spectroscopic apparatus utilizing an interferometer of the Michelson type for determining the absorption coefficient or refractive index of a sample as a function of frequency, two identical parallel beams, which are modulated at different frequencies by choppers 9 and 10, are each split into two components (reflected and transmitted) and recombined by a semi-reflector 3 and two mirrors 4 and 5 arranged as shown, at least one mirror being movable to vary the path difference between the reflected and transmitted components, the two resulting beam being received by a photo-cell 15 (Golay type) whose output is processed by circuitry, Fig. 3, for giving a measure of the amplitudes of the components of the detector outputs of each beam. The sample is positioned in the path of either the reflected component or the transmitted component for refractive index determination, or, for absorption measurements, the sample is positioned in the path of one of the beams before splitting or after recombination. The output of the detector 15 is fed to a band pass filter 16 or 17, which is arranged to pass frequencies corresponding to the frequency of one of the choppers 9 or 10. The filtered signal is then amplified and fed to phase sensitive detectors 20 or 21 also receiving reference signals from photocells, one adjacent each chopper Fig. 2 (not shown) which periodically interrupt radiation from a corresponding source on the opposite side of each chopper blade. The phase sensitive detectors output is then smoothed in a low pass filter 22 or 23 to provide a D.C. signal proportional to the amplitude of the component of the respective beam incident on the detector, and this D.C. signal is passed under the control of a logic circuit 24 to an analogue to digital converter 25 whose digital output is recorded on paper/magnetic tape etc.

Abstract: 1,236,069. Electronic counters. HITACHI Ltd. 31 Oct., 1968 [6 Nov., 1967], No. 51630/68. Heading G4A. [Also in Division H3] A cross-coupled type bi-stable circuit, shown in Fig. 8 as T1, T5, T9, T10, and connectible in a chain with similar circuits is switched by two trigger circuits driven by an inverter. Each trigger circuit comprises two field-effect transistors in series, T2, T3 and T6, T7 the gate of one being fed from the output of an inverter 3 and the gate of the other being fed via a further field effect transistor T4 or T8 with the switching signal supplied to the input of the inverter. A common transistor (T2<SP>1</SP>, Fig. 10, not shown) may replace transistors T2 and T6. In operation, when T1 is off and Vin is zero T4 conducts and charges the gate capacitance of T3. Accordingly when Vin becomes negative T3 remains on and as T2 becomes conductive conduction through T2 and T3 switches over the bi-stable circuit to the state in which T1 conducts. The next negative excursion of Vin again reverses the state. False operation due to T2 and T4 conducting together is avoided as the switching of the output of the inverter 3 is delayed with respect to the input.

Abstract: 1447623 Internal shoe-drum brakes; wear adjustment GIRLING Ltd 15 Nov 1973 [17 Nov 1972] 53120/72 Heading F2E An internal shoe drum brake has the shoe 2 adjustable to take up lining wear by the cooperation of an inherently resilient pawl member 10 and a co-operating member 7 formed with teeth 9 with which the pawl member 10 is in engagement, one member being mounted on or forming part of the web 8 of the shoe 2 and the other member being mounted on the stationary back plate of the brake. In the illustrated embodiment, the cooperating member 7 is the form of a satchet plate secured to the web 8 and having a raised central port formed with satchet teeth 9. The pawl member 10 is a C-shaped member formed from resilient sheet metal; one limb 11 engages the web opposite the satchet plate 7 and the free end of the other limb 12 engages the ratchet teeth 9. The free end of this limb 12 is divided by slots (13) to form three tongues (14, 15, 16) of progressively varying length to provide a fine adjustment with a relatively coarse tooth pitch on the rachet plate 7. The pawl member 10 is mounted on a pin 17 fixed in the backplate 5 which pin 17 passes through aligned holes 18 in the limbs 11, 12 these holes 18 allowing free radial movement of the pawl member 10 equal to the desired clearance between the shoe 2 and the drum. The pawl member 10 can move axially on the pin 17 so that it maintains its correct position relative to the rachet plate 7 if there is axial movement of the shoe 2. If sufficient wear on the brake lining has occured then during a brake application the limb 12 rides over one or more teeth 9 and holds the shoe 2 in a new adjusted position when the brake is released. The brake shown is two leading-shoe brake with shoes 1, 2 actuated at one end by hydraulic actuators 3, 4; the other end of each shoe 1, 2 engages on inclined torque-taking abutment 6 on the actuator for the other shoe.
