Title: Improvements in and relating to porous ceramic objects
IPC: C04B38/06
Filed: 1934-08-30
Abstract: Highly porous ceramic objects are produced by moulding a mixture of clay, fine sand and a finely divided combustible material, in the absence of fluxing materials, pricking the surface of the objects and baking at a fairly low temperature. The objects may be hollow spheres of 2 to 6 ins. diameter, the interior of which contains a pad or sponge impregnated with perfume, deodorizer, insecticide, disinfectant and the like, or rounded lumps of about 1/2 in. diameter for use as pipe plugs.  The pipe plugs may be pricked so that there are one or more passages extending completely therethrough and a pin may be incorporated to hold them more firmly in the pipe.  An example of a mixture is 3 parts of marl clay, 1 part of sand and 2 parts of sawdust, both the latter passing a 100 mesh sieve.  The moulded objects are then fired at 500 to 600 DEG  C.  For pipe plugs Cherrywood sawdust is preferably used as the combustible material.ALSO:Highly porous ceramic objects are produced by moulding a mixture of clay, fine sand, and a finely divided combustible material, in the absence of fluxing materials, pricking the surface of the objects and baking at a fairly low temperature.

Class 78 (4) The pivoted rams 1 which swing a rear door 4 to push refuse into the body of the vehicle shown are disposed near the roof of the vehicle so as not to impede the passage of the refuse. The arms 3 carrying the door 4, over which the refuse is tipped into an intermediate chamber 14, are pivoted at their upper ends to the ramrods 2 and at 6 to a pair of links 5 formed with stops (not shown), for limiting movement of the arms 3 about the pivots 6 so that when the rams 1 are retracted from the position shown in Fig. 1, the arms 3 and links 5 are swung about pivots 7 on the sides of the vehicle to open the rear of the body of the vehicle for discharge by tipping. Suitable stops prevent downward movement of the links 5. Prongs 16 are retracted, during the inward movement of the door 4, into an inner door 8 which is pivoted on the links 7 coaxially with the arms 3 and is fitted with spring-pressed plungers which normally engage stops 9 on the vehicle sides to prevent the inner door from swinging outwardly. When the arms 3 and links 5 are swung about the pivots 7 the inner door 8 is raised and the spring-pressed plungers escape from the stops 9 to allow the inner door to swing out when the body is tipped. The plungers subsequently re-engage the stops 9 on the first inward stroke of the door 4. A control separate from that for the compression movement of the door 4 may effect the opening movement of the door. Shields around the rams 1 may protect them from the refuse. Specification 441,599, [Group XXXII], is referred to.

An apparatus for punching or cutting-out articles from sheet material comprises a fixed plate 15 carrying a cutting-device 17, 18, a stripper plate 13 resiliently separated from the fixed plate and having an aperture to allow the cutting-device to protrude therethrough, and a punch pad 24 which is maintained separated from the stripper-plate by a predetermined gap 26 having a width at least equal to the thickness of the sheet material as the material is being severed, so that excessive penetration of the punch into the pad is avoided. The punch cutters 17, 18 (which, as shown, are for cutting washers) are located in a plate 15 resting on a channel-shaped base 11, and an annular stripper ring 19 slidable between the cutters is supported by rods 22 from a pressure-plate 12. The stripper plate 13, which is connected to the pressure plate 12 by pins 14, is held apart from the plate 15 by springs 16, and attached to the stripper plate is a guide channel 23 in which the punch pad 24 is inset so as to provide the gap 26 between it and the stripper plate. The material to be cut is fed into the gap 26 so that as the assembly 23, 24 is forced down over the cutters the gap 27 between the plates 13, 15 is closed; the gap 27 is substantially equal in thickness to the gap 26. Upon return of assembly 23, 24, the stripper plate 13 and ring 19 are raised by their springs and the cut-out washer is ejected back into the sheet material while the centre scrap slug is retained in the centre of the inner cutter 18. Alternatively, the punch pad 24 may be replaced by an endless belt which can be fed through at the same speed as the material to be punched. If desired, a resilient " take-off " sheet 25, which is perforated to accommodate the cutters, is secured to the upper face of the stripper plate, the prescribed gap 26 then being provided between this sheet and the punch pad. Instead of using concentric inner and outer cutters 17, 18, a single annular cutter may be provided and fitted internally with an annular stripper ring.
