Title: An improved machine for cleaning and digging ditches, canals and the like excavations
IPC: E02F5/04
Filed: 1954-02-08
Abstract: 760,254. Earth-excavating apparatus. POUGNET, J. L. E. Feb. 8, 1954 [Feb. 9, 1953], No. 3645/54. Class 68 (1). In a machine for excavating or cleaning ditches and the like the lower end of plates 12 are pivotally attached to laterally adjustable plates 10a coupled to a plate 10 secured to the bottom of a deflector 8 supporting a frame 1 whilst the upper ends of the plates 12 are so secured to the deflector and frame that they can be adjusted laterally thereof to permit of the forwardly directed cutting edges of the plates 10, 10a and 12 matching the desired cross section of the ditch. The material dislodged by the cutting edges is pushed laterally by the deflector 8 into a screw conveyer mounted on each plate 12 and is raised by the conveyor 16 and ejected clear of the trench by a bladed rotor 26. Rotary cutters mounted on the frame 1 shape the upper parts of the sloping side of the ditch. The moving parts of the machine are driven from a prime mover on the frame 1 and stabilizing members 46, 47 extend to the sides and the rear of the frame.
Patent GB-673725-A (GB)
Title: Method of recovering metallic oxides
IPC: C01B13/30
Filed: 1950-02-13
Abstract: The temperature of the reaction gases containing oxides formed by the decomposition of metallic halides, e.g. titanium chloride with oxygen-containing gases is reduced at least to 600 DEG C., even to 100 DEG C. or lower, by adding a colder inert gas, and the oxide is thereupon removed from the reaction mixture.  The reduction in temperature by this means is sufficient to permit further withdrawal of heat from the reaction mixture by indirect cooling without the material of which the cooler is made being attacked by the halogen present.  The cooling walls may be made of aluminium which may have been pretreated to provide an oxide film.  The indirect cooling may take place at least in part simultaneously with the removal of the metal oxides by employing cooled dust separators made of metals. Cooled air or dust-free reaction gas, or inert gas (including liquified inert gas) or the halogen of the reaction gas may be used for the temperature reduction. Specification 661,685 is referred to.

Title: Improvements in light-sensitive steering and direction-finding devices
IPC: G05D1/06
Filed: 1947-02-07
Abstract: 653,431. Automatic steering control systems. MELIN, F. L. Feb. 7, 1947, No. 3696. Convention date, Feb. 7, 1946. [Class 38 (iv)] [Also in Group XL (b)] In an automatic system for steering towards or indicating the direction of a body, light from the body is focused on to a dome-shaped system of light-sensitive cells, each of triangular or trapezoidal form, arranged symmetrically with respect to the major axis of the focusing system, and the output of the cells is amplified to actuate the steering or indicating means. In Fig. 1 an annular light source 7 co-operating with a projector 6 illuminates a body (not shown), reflected light rays 4, from which are focused by a concave mirror 1, co-operating with an auxiliary mirror 2, to a spot D on a dome-shaped group of light-sensitive elements 3 arranged symmetrically with respect to the major axis O of mirror 1. Fig. 3 shows a suitable arrangement of triangular light-sensitive elements A1-A12. Each light-sensitive element is associated with an amplifier energizing two sets of opposed coils electromagnetically moving the light-sensitive system to indicate the direction of the body or steering a moving body on which the system is mounted so that the spot D is symmetrical with respect to axis O. The number of amplifiers may be reduced by grouping the light-sensitive elements. The light-sensitive elements may be further sub-divided into annular trapezoidal elements which may vary in resistance according to their distance from axis O to introduce a damping effect. To reduce the effect of variation of distance from the luminous body, non- linear operation of the elements may be utilized. Light source 7 and its projector 6 may be adjustable and/or associated with screens or stops, while if the object is itself luminous the light source is dispensed with. Restriction to infra-red, visible or ultra-violet light is referred to. A biconvex lens may be substituted for mirrors 1 and 2.

The bars 18 are moved outwardly by axial movement of cam bars 24 carried by an actuating rod 26 extending through the main shaft 14, inclined surfaces 22 on the cam bars 24 engaging inclined surfaces 20 on the bars 18. A nut 67 on the shaft 14 is engaged by the ends of the bars 18 to take up longitudinal force exerted thereon from the rod 26. The rod 26 is reciprocated by four sets of toggle levers 32 spaced therearound. The outer ends of the levers are pivoted at 50, 52 to thrust blocks 54, 56 respectively, the block 54 being rotatably mounted but not allowed axial movement on an extension 58 of the shaft 14 and the block 52 being similarly mounted on'the rod 26.

Title: Improvements in the construction of contact lenses for the eye
IPC: G02C7/04
Filed: 1946-02-09
Abstract: 607,641. Contact spectacle lenses. FORKNALL, A. J. Feb. 9, 1946, No. 4083. [Class 97 (i)] The corneal lens is mounted with its edge in a groove of the scleral rim so shaped that the sides thereof contact the corneal lens surfaces. The groove may be formed by an extended lip which acts as a seat for the corneal lens which is secured thereon by a ring attached to the rim. As shown in Fig. 2, the scleral rim A as of synthetic resin is grooved to allow insertion of a corneal lens C as of glass, the rim being moulded around the lens which before insertion in the mould is coated around its peripheral margins with a material formed as from a rubber base. This material allows of slight movement in the rim and thus obviates any cracking of the lens. To provide better adhesion for the material, the edge of the corneal lens may be roughened or annular grooves E may be formed therein. In another form, the corneal lens and scleral rim may be formed separately, the rim A having an opening G and an extended lip 4 forming a seat for the corneal lens which is retained thereon by a retaining ring K, Fig. 6. This embodiment allows of the use of trial lenses to determine the corneal lens having correct refractive properties, since a lens may be seated by the application of a suitable wax to the rim and the lens. The corneal lens may be formed of synthetic resin having a coefficient of expansion substantially the same as that of the synthetic resin of rim A, and thus obviating the use of the resilient material.
