A fuel filter unit which can be used for separating water from the fuel comprises a pleated synthetic resin-impregnated paper cylindrical element 1 (Fig. 1) co-axial with but spaced from a centre imperforate tube 5, the upper end of element 1 being sealed to annular end cap 3 which is sealed to the upper end of tube 5, the lower end of the element being sealed to annular end cap member 4 which is radially spaced from the centre tube, and the lower end has sealed thereto a co-axial annular base plate member 8 which extends below the lower end cap member 4 and is axially spaced therefrom to form therebetween a shallow annular outlet passage 9 which at its inner end opens into the annular space 11 between the element 2 and tube 5 and its outer end opens substantially adjacent the outer periphery of the element. The end caps 3 and 4 may be made of plastics material or metal. In the embodiment of Fig. 3 in which a filter unit is incorporated in a housing fuel entering at 47 travels inwardly through the element 32 where water separates out by coalescing, downwards through space 40 and ports 39, the fuel then travels upwards inside tube 35 while the water collects in vessel 44, and the fuel leaves the housing.

Title: Improvements in or relating to finger splints
IPC: A61F5/058
Filed: 1948-03-31
Abstract: 634,069. Surgical splints. GODFREY, J. DE L. March 31, 1948, No. 9128. [Class 81(ii)] A finger splint, primarily for holding the distal phalanx in the hyperextended position in cases where the breakage of the bone has resulted in detachment of the entensor tendon, comprises a frame extending along each side of the finger and two adjustable slings for supporting the intermediate and distal phalanges. As shown, attached to a forefinger, the yoke or frame comprises a loop 34 engaging the back of the proximal phalanx and legs 33 in which are slots 39, 51 by which are adjustably attached the intermediate sling 37, engaging the back of the intermediate phalanx, and a front sling 45, engaging the front of the distal phalanx. The screws 41, 52 holding these slings extend through to the opposite leg of the yoke and between the legs, they carry tubular spacers. Preferably all the parts, except the screws, are made of a synthetic plastic material so that the parts can be readily moulded to shape and can be set into 'a rigid whole by the application of a solvent or cement at the junctions of the slings with the yoke. It also facilitates cutting off the superfluous length from the legs of the yoke after the splint has been set.

Abstract: 1,254,206. Light modulation. COMMISSARIAT A L'ENERGIE ATOMIQUE. 20 Feb., 1969 [1 March, 1968], No. 9148/69. Heading H4F. An electro-optical cell for the phase displace. ment of a polarized light beam particularly for use in a fast light shutter for triggering a pulsed laser beam comprises two flat outer electrodes 44, 46 inserted in the outer conductor of a coaxial cable and a flat central electrode 124 inserted in the central conductor of the cable, and two crystals 120, 122 which exhibit the Loches effect, e.g. potassium dihydrogen phosphate or potassium nitrate, are diposed between the electrodes with their principal crystallographic axes at right angles to the electrodes and are rotated at 90 degrees to each other so that the successive phase displacements of the polarized beam passing therethrough are additive. The cell may be completely impedance matched with the coaxial cable, which can form part of a D.C. circuit or terminate in a short circuit, so that a voltage step giving a phase displacement of 180 degrees and having a rise time of e.g. 0À5 nsec. may be applied without any resultant deformation. The flat electrodes are provided with apertures 130, 132, 134 for the light beam, and layers of copper and flexible indium plates 125 are inserted between the crystals and electrodes except at the apertures. Placed between crossed polarizers, the cell acts as a light shutter.

[Class 37] A wire-wound rheostat of tubular or rod form utilizes a roller contact which is inherently resilient, for example, a coiled spring. In Fig. 2, movement of the slider 6 along the control worm 5 by rotation of crank 7 rolls the central convolutions of the coiled spring 18 along the resistance element 2 and the central convolutions of the coiled spring 23 along a current collecting rod 8. As shown in Fig. 3 the end convolutions of the coiled spring 18 are secured to opposite. ends of a hub 19 screwed on to the spindle 15 which latter rotates in bearings 14 enclosed in mounting 13 which is secured through insulation 12 to the slider 6 ; the coiled spring 23 which is identical with the spring 18 is similarly mounted. The parts are relatively positioned and assembled to ensure balanced arrangement of the two rollers 18, 23 with respect to the slider 6 and sufficient pressure to ensure that the central convolutions are deformed to the shape of their tracks on their corresponding raceways. In a modification the member with which the roller 23 makes contact is a tube and the current collector the control worm 5.

Abstract: 942,133. Pulse radar. ELLIOTT BROS. (LONDON) Ltd. March 11, 1960 [March 19, 1959], No. 9633/59. Drawings to Specification. Heading H4D. In a pulse radar target and missile-tracking system, the aerial system follows the target automatically and the missile bearing and elevation relative to that of the target and range are displayed on a C.R.T. The target range unit scans downwards from maximum range until it detects and locks on to a target. The missile range unit scans from a minimum range. The target and missile echo signals in elevation and bearing are passed through receiver channels, the gains of which are selectively controlled to permit the alternate transmission of target and missile echoes during alternate intervals between transmitted pulses. The receiver output serves to control the aerial setting and to produce the display signals. The missile is directed towards the target by correcting signals from the ground, transmitted either by an observed or automatically by means not shown.
