Abstract: 1459271 Spot-type disc brakes for steerable driven wheels SOC ANON AUTOMOBILES CITROEN 7 March 1974 [7 March 1973] 10326/74 Heading F2E A vehicle wheel and brake assembly includes a brake disc 7 having a single, inwardly facing, friction surface 7a. As shown, the assembly comprises a wheel support 1 pivoted by means of two knuckle joints 3a, 3b respectively on arms 2a, 2b, rigid with the structure of a motor vehicle. A hub 11b driven by element 11a rigid with a transmission shaft 4, is rotatably mounted in the wheel support 1, and has secured to it by bolts 13 under tension a radially-extending plate 12 on whose inward side is secured brake disc 7 and on whose outward side is secured an annular member 6a which forms with rim 6 a wheel whose opening is directed inwards. Relative rotation between plate 12 and disc 7 is further prevented by engagement of bolt heads in certain disc grooves 16. Two brake pads 21a, 21b, Fig. 6, are applied by pistons 19a, 19b respectively in cylinders fed at 20, Fig. 1. A mechanical emergency brake 9, Fig. 1, is applied by a cable and scissor-levers (Fig. 8, not shown). The disc may be integral with the plate, (Fig. 4, not shown) and ventilating openings provided for centrifugal cooling; co-operating orifices in annular member 6a are provided. In Fig. 5 (not shown) where the disc and plate are separate, oblique openings in the plate communicate with the disc grooves shown in Fig. 2 at 16. In Fig. 3 (not shown) the central transverse part of plate 12 is omitted and hub 11b is extended outwards and has a radially extending shoulder between which and the hub bearing the axial part of plate 12 is fixedly located. In all cases the plate 12 has radial ribs, and these, together with the bolts 13, Fig. 1, or equivalent bolts, or the Fig. 3 arrangement, are sufficiently strong to resist the axial force generated by braking on face 7a. The hub and plate may be integral.

[Class 83 (i)] An independently portable sand-holding cartridge for interposition between an air reservoir 6, having a discharge port controlled by an air valve 14, and a core-box C and supporting platform, comprises a charge-holding body portion 27 shaped so as to keep the sand concentrated, and a short base portion 28 of increased width for spanning the core-box C, said base portion being provided with an opening or openings for registering with the opening or openings in a particular core-box or series of core-boxes. The cylindrical body portion 27 preferably contains just enough sand to fill the core-box and is filled by hand from a conveniently placed heap. The air reservoir 6 is capable of vertical movement by operation of a handle 10 through a rack 7 and a pinion 8, thus allowing the container to be gripped between the core-box and the bottom of the reservoir where it seats on the sealing-ring 31. Opening of the valve 14, Fig. 5, which in a preferred construction has a flange 18 normally held closed on a gasket 20 by air pressure and a spring 21 and opened by hand operation of a handle 22 through a valve stem 24, forces sand through openings 29 in the base 28 of the container and into the core-box cavities 25. Sand containers are made to fit any type, size or shape of core-box, the machine set up remaining unchanged. The machine is stated to be suitable for the use of sand with a moisture content of from two to five per cent.

Abstract: 1,092,341. Hydraulic shock absorbers. GIRL. ING Ltd. June 10, 1964 [March 15. 1963], No. 10429/63. Heading F2S. An hydraulic shock absorber comprising a piston and cylinder assembly 15, 10 is provided with a piston by-pass 18, 19 through which, in normal reciprocations of the piston, liquid passes freely from one end of the cylinder to the other. An inertia mass 20 is mounted in the shock-absorber assembly such that, on sudden shock, the mass actuates a valve means which at best partly restricts the by-pass. The mass is spring-loaded into its equilibrium position by a single spring 21 or two springs are mounted at each end of the mass. The by-pass may be constituted by a passage through the piston-rod, the mass being slidably mounted about the piston-rod. The valve means may comprise a rotary valve 25 which is attached, through an arm 27 to the inertia mass 26<SP>1</SP>. The by-pass consists of two flexible pipes 30 and the rotary valve, the valve being mounted on the frame 11  of a vehicle. The valve is spring-loaded by means of a rubber bush through which the spindle of the valve passes. The housing of the valve may be mounted on the shock-absorber cylinder (Fig. 2, not shown). Two rotary valves may be mounted in series (Fig. 5, not shown) or parallel, the arms of the inertia masses having different lengths and the inertia masses being of different mass. The inertia mass may form part of a reciprocating valve member (Fig. 4, not shown).

[Class 97 (i)] A range or height finder for aircraft, ships, &c. having a known dimension comprises a rod or stick a, or a pencil, pen, or a tubular case for a pen, pencil &c. having a scale b on each of one or more sides, together with the names of the aircraft or ships for which the scale is appropriate. The rod is held at a predetermined distance from the observer's eye and the apparent length of the aircraft &c. is measured on the scale appropriate to its type. Measurement may be determined by using the observer's thumb nail or by a sliding cursor j reading on all scales ; the cursor enables identification of the aircraft to be postponed until after measurement has been made. A loop of cord secured to a split pin e driven into a plug d may be provided to facilitate holding the rod at the predetermined distance, the eye f of the pin being placed against the observer's cheek and the loop being taughtened round a groove k in the rod. The cord, when out of use, may be wound round the pin e and the plug d may be inserted in an open end of the rod. The scales may show height when the observation is vertical, or distance. Additional scales may show heights for observations at given angles of elevation, or the length of the pin and plug may be such that, if they are used to determine an extension of the observation distance, the scales for vertical observation may also serve for observations at a given angle of elevation.

Abstract: 1520833 Charge coupled device GENERAL ELECTRIC CO Ltd 16 March 1977 [16 March 1976] 10495/76 Heading H3U In a charge coupled device some charge is unavoidably left behind at each transfer. This can be counteracted by only putting charge packets into the input of the device at every rth cycle of the stepping voltages, the charge left behind does not interfere with the next input packet, and is itself stepped along the device. By summing at the output the main output packet and the succeeding r-1 packets the efficiency of the charge transfer is increased. The summing may be carried out by sequentially stepping r times with one output electrode or by parellel readout fom r electrodes (not shown).
