Abstract: 444,490. Moulding pulp sheets &c. BASLER, H., 7, Am Zirkus, Berlin. Sept. 20, 1934, No. 27085. [Class 87 (ii)] In moulding sheets or slabs from pulp wherein the pulp is given a preliminary pressing and then subjected to a final pressing with the simultaneous application of pressure, vacuum and heat, the pulp is introduced into a pre-shaping mould having a closable perforated base 4, 5 while the base is closed, the base is rapidly opened, and pressure is simultaneously applied to remove the greater portion of the liquid. The pre-shaping press comprises a mould frame 3 and the base is formed by a fixed perforated plate 4 and a horizontally-movable perforated plate 5 which can be displaced into a groove 7 by a pinion 7a so as to place the perforations out of register and close the base. A loose perforated plate 10 is placed on the plate 4. The plates are supported by a carrier frame 9 mounted on a ram 8. In use, pulp is supplied from a container 2 by a rotatable feed pipe 2a and a cover 11 is lowered and fixed on the frame 3. The plate 5 is displaced to open the base, the interior of the frame 9 is connected to vacuum by a pipe 9<a> and the ram 8 is raised. The sudden opening of the base creates a vortex effect to cause some of the fibres to assume a sloping or vertical position After pressing, the cover is raised and a trolley carrier is wheeled over the mould. The carrier comprises a U-iron frame carrying displaceable knife-edged sheets adapted to engage under the moulded slab. The slab and plate 10 are ejected by the ram and are passed through the carrier, secured thereon and removed to a final pressing apparatus, Fig. 6. The final pressing plates 21, 26 are secured on a ram table 19 and a press cover 25 respectively. The plates 21, 26 are provided with grooves or slots 21a and with heating coils 22 and are covered by perforated plates 27. The grooves 21<a> are connected to a vacuum pipe 24 and the coils 22 to heating conduits 23. The table 19 is carried by a ram 18 and the plates are pressed together within a frame box 16 slidable on rods 17. The plate 21 is adjustable on the table 19 by screws 20. The perforations on the plates 22, 27 are greater in number per unit surface and the heating coils are closer towards the centre of the plates. This enables drying to be uniform across the slab Soft porous slabs, heat and sound insulating slabs or hard slabs are produced according as the pressure is increased. Before the final pressing the slab may be re-impregnated with 25 to 30 per cent of water and then pressed at temperatures above 160‹ C.

A constructional toy comprises two plates, one adapted to be superimposed on the other, and both having slots for receiving a locking member which also engages a main component, the plates being capable of relative movement which results in the locking together of the plates and the locking member which member also secures the main component. A toy car consists of a plate constituting a chassis 8 having a slot 8D and provided with strips 8A, axle slots 8B and guide lugs 8C, the lugs locating a locking plate 7 having three T-slots S<SP>1</SP> and a front bumper member 7D. A main body member 14 is adapted to rest on ledges L formed on wings 9-12 and to engage over the rear end of a bonnet 15 which has lugs 15A for engagement in slots 16A<SP>1</SP> of a radiator 16. To assemble the toy the wheel axles are dropped in slots 8B and the chassis 8 is superimposed on the plate 7 so that the slot part 7A and slot 8D coincide. Wings 9-12 are then placed in position with their ledges L within the chassis strips 8A. After placing lugs 13A<SP>1</SP> of a main lock member 13 in slots 14A<SP>1</SP> of the body 14, the body is placed on the already set-up parts so that the T-head of the lock member 13 passes through the slot part 7A and slot 8D. The locking plate 7 is then slid rearwardly for a limited amount relative to the chassis and the assembly thus locked. In this initial locked position the front slot S<SP>1</SP> is fully exposed between the bumper 7D and the front edge of the chassis whilst at the other end of the chassis, the part 7C only of the rear slot is exposed. The bonnet 15 is next secured by passing its rear below the front of the body 14, the bonnet front being held by the radiator 16 of which the lower T-portion passes through the slot part 7B. Further rearward movement of the locking plate 7 now locks the radiator, side slots 16B<SP>1</SP> engaging in the slot part 7B. Finally, a rear lock plate 17 and a rear bumper 18 are positioned in the rear slot of the locking plate 7. The assembly is broken down by removing the rear bumper and rear lock plate, sliding the locking plate forwardly to enable the radiator to be withdrawn, and further sliding said plate until the main lock member 13 can be released.
