Abstract: 1308625 Compression moulding concrete &c H JAEGER 26 May 1970 [30 May 1969] 25169/70 Heading B5A [Also in Division B8] Articles of concrete or like mouldable material after moulding in a mould open at the top and bottom, the latter resting an a support surface, are slid in the mould along the support surface and removed from the mould and stacked on a platform in a stacking zone, the platform being lowered as the articles are removed. As shown, liquid mouldable material 3 is fed from a hopper 2 via an outlet 4 controlled by a regulating flap 7 into a container 5. The container 5 is moved by a piston 6 to overlie a mould 9 having compartments 14 and resting on a support surface of a table 10. The liquid material is discharged from container 5, which is then withdrawn, and is subjected to vibrations from a means 12 for a predetermined time and to pressure from heads 15 of a press 11. When the material has set, the mould and press are slid across the support surface to overlie a layer 22 of articles made in the preceeding cycle and stacked on a pallet 26 on a lift 17 operated by a ram 18. The lift 17 and heads 15 are lowered to eject the articles and the press and mould are returned. The lift 17 is rotated through 180 degrees to acheive staggered layers of articles and a means 23 places a sheet 25 of chemically treated paper, plastics, metal, cardboard, or wood over the top 24 of the layer.
Patent GB-253213-A (GB)
Abstract: 253,2.13. Shannon, D. M. Feb. 13, 1925. Cylinders, arrangement of ports in.-In a twostroke-cycle engine, scavenging ports are arranged to be connected by control valve to the exhaust pipe at one part of the cycle, for providing additional opening for exhaust, and to the scavenging- air pipe at another part of the cycle. Fig. 1 shows a double-acting engine having exhaust ports E and scavenging ports F, each occupying one-half of the circumference of the cylinder. the annular chamber surrounding them being provided with diametrically opposite control valves G<2>, Figs. 1 and 1A, which are shown in the closed position, separating the ports E and F. When the ports are first uncovered by the piston, the valves G<2> are open, so that exhaust occurs through both sets of ports; when the cylinder pressure falls to that of the scavenging- air, the valves G<2> are closed automatically, and scavenging-air enters the ports F from the main J and past a valve H. The valves G<2> are flap valves controlled by springs g<6> and actuated automatically by the pressure of the exhaust gases and scavenging-air. Figs. 4 and 5 show a combined valve G<3>, H<3> for performing the functions, the butterfly portion G<2> controlling the connection between the exhaust space B and scavenging space C by engaging seats g<7>, g<8>, and the oscillating disc portion H<3> controlling ports h<3>, r<1> which admit the scavenging-air to the ports F when the portion G<3> is closed on to the seats g<7>, g<8>. In another form, a double flap valve acts automatically to perform both functions. Fig. 7 shows an oscillating or intermittently rotated disc valve H<@5> arranged near the ports F so as to control the admission of scavenging- air thereto; the semi-annular space C is divided into two portions, each of which is fitted with a valve H<5>. The valve H<5> may be spherical. The ports F may be longer than the exhaust ports E, so that supercharging is obtained after the piston has closed the latter. Fig. 11 shows a double-acting engine having exhaust ports E E<1> and scavenging ports F<5>, F<6> on the same side of the cylinder, supplementary exhaust and scavenging ports being arranged at F<3>, F<4>. In modifications of this form, the ports F<5>, F<6> may be combined into a single set. The air entering through ports F<3>, F<4> is deflected at an acute angle to the cylinder axis by a bridge piece arranged around the ports.

Abstract: 659,376. Testing physical qualities of materials. LAING, J. W., and STARNES, P. E. Oct. 7, 1949, No. 25841. [Class 106 (ii)] [Also in Group II] Apparatus for measuring the consistency of paste or slurry in a revolving mixing pan comprises an arm or frame mounted to pivot about a vertical axis over the pan and carrying a pointer over a scale, means such as a spring presenting an opposing force to pivotal movement of the arm or frame, and a blade carried by an arm depending from the frame for immersion in the paste or slurry. As described, the frame B is mounted on bearings C to pivot against the pull of a helical spring P. The blade H which is immersed in the paste or slurry is carried by means, including an arm G, which permit the blade to be swung to an inoperative position and to be adjustably positioned at any radial distance along the frame B. A pointer F secured to the frame B moves over a scale marked on a fixed peripheral rail E, the displacement of the pointer giving a reading of consistency. The apparatus is stated to be of particular advantage in the manufacture of chemically-aerated cellular concrete from pulverized fuel ash.

Abstract: 1311897 Valves WESTINGHOUSE BREMSENUND APPARATEBAU GmbH 29 May 1970 [29 May 1969] 25948/70 Heading F2V An hydraulic control valve having an inlet 7 which can communicate with either of two outlets 20, 22 comprises a spool having a bore 28, a valve member 35 and latching means 31a, 31b. When the spool is in the neutral position, as shown in Fig. 1, fluid at the inlet passes to the reservoir via line 19. When the spool is moved upwards by the control rod 3, fluid pressure opens the non-return valve 35 and passes via line 20 to one side of a motor 21. The fluid pressure difference acting on a sleeve 29 within the spool causes it to move relative to the spool and force the locking balls 31a, 31b into grooves in the body. Should pressure build up in the outlet 20, the valve member 35 returns to its seat and the spring 38 forces the sleeve 29 into the spool. A spring 41 is then able to return the spool to its neutral position. A latching device may be provided at either end of the spool (Fig. 3, not shown) or the spool may be locked in either end positions by a common latching device (Fig. 4, not shown).
