Filed: 1975-04-01
Abstract: 1463936 High absorbency clays CULLINAN HOLDINGS Ltd 1 April 1975 [8 April 1974] 13142/75 Heading C1A [Also in Division A5] Clays are treated to produce compositions having a greater liquid absorbency by forming a cake comprising an intimate mixture of the clay in a finely divided form together with finely divided asbestos, diatomite or heat expanded perlite and heating the cake to a temperature between 450‹ and 780‹ C. The mixture may contain more than 70 wt. per cent of clay, and the mixture may be formed by comminuting together the components of the mixture so that they pass through a 150 ASTM screen. The mixture may be held at the firing temperature for up to 3 hrs., and the fired cake so formed may be comminuted to yield a granular product. The preferred clay is attapulgite; a flint clay, a plastic clay, kaolin and shale are also exemplified. The clay containing materials with the increased liquid holding capacity may be used in granular form as a carrier for pesticides. Examples illustrate the absorbency of clays with and without the additions and the dependence of this property on particle size, firing temperature and heat-soaking treatments.

Abstract: 611,581. Angle measuring. WILD SURVEYING INSTRUMENTS SUPPLY CO., Ltd., H. May 3, 1946, No. 13548. Convention date, May 15, 1945. [Class 97 (ii)] An arrangement for transferring a horizontal direction, e.g. a line D, Fig. 1, at the bottom of a pit to a horizontal plane at a different level comprises a vertical telescope L2, whereby the line D is simultaneously viewed directly and through a deflecting prism P, and a horizontal telescope L1, the whole being turnable about a vertical axis Y1, Y2. The angle between the line D and a reference line at the surface defined by an aiming mark Z is measured by adjusting the base of the prism P to lie perpendicularly to the reference line by autocollimation in the telescope L1 and subsequently measuring the angle through which the apparatus must be turned in order that the direct and deflected images seen in the telescope L2 may be in parallel alignment. Alternatively, the apparatus may be used at a bottom of a pit and both telescopes may be horizontal, an inclined mirror being provided for vertical sighting. In the arrangement shown in Fig. 6, a single horizontal telescope is employed into which direct rays from the object line and rays deflected by the prism P are reflected by mirrors G1, G2, the mirror G1 is retracted for viewing the sighting mark for establishing the datum line at the level of the telescope. As shown in Fig. 1, the deflecting system P comprises a prism in the form of an isosceles trapezoid, but any deflecting system with an odd number of reflections, such as that shown in Fig. 11, may be used. A plane parallel plate may be provided for lateral displacement of the direct image of D for finer adjustment with the displaced image. The telescopes may be mounted in a frame provided with polygonal shaft ends by means of which they may be sighted upwardly or downwardly, the support including an indexed rotatable plate which co-operates with a fixed plate on the base.

[Class 40 (ii)] In a magazine gramophone the records 1 to be played are stacked on supports 2, 3 and a centre post 4 above the turntable and the lowermost record is fed from the stack by being displaced to bring its central aperture in register with the top of the post 4 and to clear supports 2, the movement of any other record being prevented by a stop 11 which is positioned by afeeler 13 which resiliently engages the lowermost record. In the examples described, stop 11 and feeler 13 are constituted by a single pivoted member mounted in a slot on post 10 and acted on by a coil spring, not shown. Supports 2, 3 are carried on posts 5, 6 having pushers 19, 20 for displacing the lowermost record and conical tops co-operating with guide 9 on post 10 to position records in the magazine. The under surface 16 of guide 9 limits the movement of member 11, 13 under its spring in the absence of records. After playing, records may be removed up post 4 by lifting their edges over supports 2, 3, but members 9 and 11, 13 may be arranged to yield to allow records to be lifted straight off the post, Fig. 4 (not shown). In this case, member 11, 13 is not biassed fully upward by its spring, but to an intermediate position. In order to counterbalance the retarding effect of feeler 13 on the falling records, the post 4 may - be inclined, Fig. 6 (not shown). The rising of feeler 13 in the absence of records may control a stopping device for the machine. Posts 5, 6 and 10 may be'movable manually to accommodate stacks of records of different sizes.
