Title: Method and apparatus for making a cementitious wedge shaped slab
IPC: C04B28/04
Filed: 1973-11-01
Abstract: 1450719 Pressing and vibrating wedge-shaped slabs CALIFORNIA CEMENT SHAKE CO Inc 1 Nov 1973 [2 Nov 1972 6 Nov 1972] 50773/73 Heading B5A A wedge-shaped cementitious slab is formed by casting a slurry into a mould having vertically disposed side walls 44a, 44b (Fig. 5) and a screen floor 44 inclined to the horizontal, the screen floor 44 is placed on a support that is vibrated horizontally in the direction of inclination of the screen floor, and excess water is squeezed from the slab. A. described to mould a wall slab or roof shingle, slurry is cast from a hopper 37 (Fig. 3) into the mould 29 with the screen floor inclined, the upper surface of the slurry being free to assume a horizontal position. A support 46 is vibrated as above while supporting the mould, which is then moved by an endless, perforated conveyer 57 beneath interconnected rollers 52 that apply increasing pressure to the slurry through a patterned plate 50 (Fig. 3) and plastics sheet 49, to squeeze water out into a trough 56 (Fig. 3). The plate 50 and mould wall portions 44b are removed and the slab scooped off the screen floor (see Fig. 8, not shown). The mould &c. is placed on a return conveyer 60. A further conveyer feeds the slab through an oven having radiating heat and air drying. The slurry comprises a mixture of Portland cement, perlite (volcanic glass powder), an aqueous mixture of glass fibre and cellulose (e.g. cardboard), slaked lime (e.g. quick lime, water and tallow), water, accelerator, colorant and an air-entraining agent; the mixture is claimed in the Divisional Specification 1,450,720. The slab has a striated and stepped surface.

The surfaces 2-5 may be aerodynamic control surfaces but are preferably jet deflectors located in the XY and XZ planes of the missile, Fig. 1, in a YZ plane not passing through the centre of gravity, and in response to a binary signal α representing a roll command and binary signals # and γ representing combined pitch and yaw commands in planes bisecting the XY and XZ planes, each deflector receives a binary signal of the Boolean form α(# + γ) + #γ. The deflectors can assume positions causing the missile to turn to the right or left or dive or climb, each in combination with a roll in one direction or the other, Figs. 3-10 (not shown), each of these eight combinations of the deflector positions corresponding to one of the eight possible combinations of α, # and γ. The appropriate signal to each deflector may be produced by one of electric circuit groups (20)-(23), Fig. 11 (not shown), the signals α, # and γ each controlling a switch in each group, or by a computer, Fig. 12 (not shown), comprising fourteen NOR gates. Alternatively the appropriate function α(# + γ) + #γ for each deflector may be calculated by one of four slide valves (100), Fig. 13 (not shown), each having four compartments either receiving an hydraulic or pneumatic pressure or being vented, depending on the respective valves of α, # and γ, and a fourth compartment receiving a constant pressure, causing the slide to move in the direction of the resultant pressure, and so directly or otherwise actuate a deflector. In a further embodiment, Figs. 14-23 (not shown), the nozzles and their deflectors are located in planes through the X-axis bisecting the XY and XZ planes, and α, #, γ represent respectively roll, pitch and yaw command signals. These may be error signals from gyroscopes or accelerometers.
