Abstract: 582,815. Calculating - apparatus. ARENCO AKTIEBOLAG. July 4,1944, No. 12772. Convention date, July 3, 1943. [Class 106 (i)] Relates to an apparatus for computing the length of one of the cathetii of a right-angled triangle in dependence of the angle between this side and the hypotenuse, e.g. for use in gunfire control apparatus, comprising a triangulation element movable in proportion to the cathetus and a guide member, having a spiral curve controlling the movements of the triangulation element, and is characterized in that the triangulation element is displaced in accordance with the rotary movements of the guide member at a ratio of tan #/k, when # denotes the angular displacement of the guide. member from a position of origin and k is a constant greater than 1. The course of a target F, Fig. 1, is represented on a horizontal plane A of known height k, and the position of its image on the plane is located by the azimuth angle sv and its distance p from the origin C, p being a function of the angle of elevation (hv), thus : p=ho.cot hv. A rotatable cam disc 7, Fig. 2, has a spiral curve 6 engaged by a roller 4 on a longitudinally slidable bar 3 carrying a stylus 2 which, as the cam disc 7 is turned in proportion to the complement of'the angle of elevation hv, is positioned a distance r from the centre of a disc of glass 11 equivalent to the cathetus p. The disc 11 is coated with non-drying paint underneath and is itself rotated according to the angle of azimuth sv of the target, so that a representation of the path of the target in the plane A is traced by the stylus 2. A frame 13 (see also Fig. 3) having parallel wires 9 is manually rotated to keep the wires parallel with the traced path of the target and this setting is introduced into the fire control instrument through bevel wheels 20. In the embodiment shown in Fig. 6, a roller 22 engaging the spiral groove 6 is restrained by a fixed guide 24 and slides also in a slotted arm 27 pivoted at a point 28 collinear with the pivot 38 of an arm 37. A shaft 40 is manually rotated to set the cam disc 7 to a position proportional to the angle of elevation and the arm 37 to the actual angle of elevation. A worm gear 45 is manually operated to vertically position a frame 30, slidable on a rod 29, in accordance with the altitude h of the target, and the point of intersection of a wire 36, carried by the frame 30, with the arm 37 is plotted on a translucent plate mounted above the wire. The vertical movement of the frame 30 effects the horizontal displacement of a pin 33 which slides in the pivoted arm 27 and is attached to a horizontal rack 32 engaging a pinion 34 and rotating it in proportion to the horizontal displacement of the target. To cater for angles of elevation less than a certain minimum alpha, the spiral groove 6 is modified beyond the point representing this angle to conform to the formula and the arm 37 is held by a stop 47.

Title: Improvements in the manufacture of building blocks and the like products from slag
IPC: C03B19/08
Filed: 1947-05-15
Abstract: 648,832. Moulding building blocks from slag. MARTIN, E. M. May 15, 1947, No. 13140. [Classes 22 and 87 (ii)] Building blocks &c. are formed from molten slag by aerating it and shaping the aerated slag in a mould, one or more of the walls of which are movable under pressure to allow for a change in volume of the aerated slag during cooling. Molten slag fed into a hopper 20, Fig. 7, is aerated in a chamber 21 by divergent jets of gas or air from a nozzle 25, Fig. 8. It then flows through an outlet 22 having a swinging gate 23 into a mould. The core of the mould, Figs. 3 and 5, is made of four corner members 3 joined by studs and slots to T-members 4 whereby both longitudinal and lateral expansion of the core is possible. The core is maintained in expanded position by weights 11, 15 joined respectively by links 7, 8 to angle-irons 10 on the corner members 3. The outer part, not shown, of the mould is a simple box, preferably having sloping sides. In a modified process, the molten slag is poured into a mould 32, Fig. 11, having along its bottom and preferably down one of its ends a channel 33 through which the aerating medium is forced, the channel having outlet apertures arranged to direct the aerating medium both outwardly and upwardly to ensure aeration of the slag throughout its width. The mould has a swinging cover 36 which may be closed after the pouring but which is permitted to move outwardly during solidification. A thermostat may be provided which prevents expansion of the mould until solidification begins.
