Abstract: 1,227,093. Incinerating waste material. R. STONE. 24 March, 1969 [29 March, 1968], No. 15217/69. Heading F4B. Waste material 10, dumped in a conbustion pit 20 is burnt from the top downwardly, by having air from blower 32 forced through it from the pressurized air space 30 above it. The combustion gases produced pass through the unburnt material below the burning layer, and the adjacent soil layer 23, which act as filters and coolers, and then through layers 40 of organically treated soil, such as manure-loam mixtures, which act as biological filters. The gas temperature in these layers 40 is kept below the dew point and pasteurization temperatures for optimum biological filtration. A layer of earth 25 covers the burning material, and the air space 30 is defined by a removable fireproof canvas cover 26. Impermeable polyethylene membranes 36 prevent the combustion gases percolating back to the pressurized air space 30. The pressurized air flow is used to dry the material prior to its ignition by gas or electric means (not shown). The method of incineration may be applied to industrial or domestic apparatus (Fig. 3, not shown) in which case downdraught combustion gases from a first incinerating container are passed through a second filtration container containing successive layers of gravel, soil and organically treated soil. The waste material may be refuse, coal, industrial or sewage sludges, animal or vegetable residues or nuclear residues.

Abstract: 1,231,866. Producing filamentary material by fibrillation. CELANESE CORP. 1 Aug., 1968, No. 36676/68. Heading B5B. Filamentary material is produced by simultaneously melt extruding through an extrusion head adapted for forming a conjugate filament or a laminated film two or more polymeric materials which differ from one another in composition or properties, the melt extrusion being carried out in such a manner that the extrudate is in the form of a conjugated filament or a laminated film and the extrudate being then fibrillated, e.g. by drawing it at a sufficiently high draw ratio while maintaining its temperature above the glass transition temperature of at least one of the polymeric components making up the extrudate. At least one one of the polymers used contains a foaming agent which is or which generates a gas during extrusion so that at least one component of the extrudate is foamed. One or both of the polymers extruded may be polypropylene. The polypropylene may be extruded simultaneously with cellulose acetate or an acetal polymer. If the extrudate is drawn to effect orientation, it may then be mechanically worked to effect or increase fibrillation. The fibrillated product is in any case preferably subjected to drawing to improve its physical properties. The polymeric materials, of which at least two are employed in preparing the product of the invention are of different composition or properties by which, in this Specification is meant that the polymeric materials are: (1) polymers of the same type, but differing in molecular weight or containing different additives; (2) polymers of different types; (3) polymeric combinations wherein one polymer is foamed prior to extrusion and another is not; (4) polymeric combination wherein one of the components has experienced a different thermal history. Suitable polymers are polyolefines, polystyrene, polyamides, polyurethanes, acrylic polymers, polyethers, halogenated polymers, cellulose esters of organic acids, polycarbonates and polyacetals. In an example, two polypropylenes which differ from one another in molecular weight and melt viscosity are separately mixed with 1% by weight of a blowing agent (azodicarbonamide) and separately melted, foamed and metered through separate entrance ports into a die assembly adapted for the production of laminated films. The two polymer streams are kept separated until they are extruded from the die, at which point the two molten films contact one another to form a laminated film. The foamed laminate is then drawn while passing through a quench zone maintained at a temperature above the glass transition temperature of polypropylene whereby it is converted into a fibrillated network structure.

Abstract: 1,237,950. Laminated spring unit. PNEUMATIQUES CAOUTCHOUC MANUFACTURE ET PLASTIQUES KLEBER COLOMBES. 23 Dec., 1968 [29 Dec., 1967; 21 March, 1968; 28 March, 1968], No. 61174/68. Heading B5N. [Also in Divisions B7 and F2] A spring unit consists of two spring elements each consisting of metal plates 5 or 6 alternating with rubber layers 3 or 4, the two elements being so arranged that when an axial load in direction C compresses the unit, the individual elements flex and approach one another so that either (as in Fig. 1) they eventually contact each other or if (as in Fig. 2, not shown) the space between the elements contains compressible material such as sponge rubber, the material in this space is compressed. The effect of this is that the stiffness of the spring unit when deformed in shear in direction B at least increases with the compressive loading in direction A. In the unloaded state, the unit may be convergentdivergent as in Fig. 1, or simply convergent (Fig. 3, not shown). In Fig. 10, the central layers 18, 19 in each of the two stacks of rubber layers 3, 4 are of rigid material and the block 9 located between them is resilient. Figs. 11 to 15 (not shown), depict units generally similar to that of Fig. 10, but with the parallel-sided layers 18 and 19 replaced by wedge-shaped members (24, 25). Figs. 7 to 9 (not shown, but see Division B7) depict spring units, similar to those described above, embodied in a rail vehicle suspension system.

Abstract: 1,239,524. Automatic control of speed. AUTOMATIC SWITCH CO. July 14, 1969 [Nov. 19, 1968], No.35317/69. Heading G3R. The average frequency of the output of an alternator is maintained equal to that of a separate A. C. source by controlling the governor of a prime mover driving the alternator by a signal proportional to the difference in frequency between pulses which are a sub-multiple of the alternator and separate source frequencies respectively. It is desired to maintain synchronism between electric clocks 16 on a load power system and a master clock 11 controlled by a tuning fork oscillater 10 which comprises the separate source. The alternator and oscillator outputs are squared in pulse shapers 17, 12 and then sub-divided, e.g. down to 0À123 Hz before comparison in a phase detector 22 in which each signal alternately changes the state of a transistor bi-stable circuit (Fig. 3, not shown). This is coupled to a further transistor switching circuits to produce a square wave of 0-20 volts whose mark/space ratio depends upon the lag or lead of the alternator frequency; if this is correct the ratio is unity. The output 22 is integrated by a capacitor network 23 to produce a D.C. voltage which deviates above or below 10 volts according to the lag or lead, and which is compared with a reference voltage of 10 volts from zener diodes in an output stage 24 so as to produce a positive or negative (or zero) voltage to control the governor of the prime mover.

Abstract: 1,250,891. Radiation source containers. NATIONAL RESEARCH DEVELOPMENT CORP. 15 April, 1969 [15 Jan., 1968], No. 2052/68. Heading H5R. A radioactive source container includes a radiation shield formed of a fixed part and a movable part which abuts against the fixed part in the closed position and which is spaced from the fixed part in the open position; a fixed radiation source holder positioned to lie wholly within the movable part of the shield in the closed position; opening means for moving the movable part away from the fixed part against continuously acting closure means urging it towards the fixed part; and a latching mechanism for holding the movable part in the open position against the action of the closure means. In the arrangement of Fig. 3c the source-holder is mounted in a central axial bore of the shield which is formed by a fixed cylinder 1 and a cylinder 2 which is axially slidable against the action of springs 4 to expose the source which, as shown, lies in the middle of the gap in the exposed position, but is offset from the plane of abutment of the portions 1 and 2 when the latter are in the closed position. Cylinders 1 and 2 may be of uranium, tungsten, or lead, and cylinder 2 may be arranged such that either the whole cylinder can be withdrawn, as in Fig. 3c, or optionally a sector 14 only, as in Fig. 3b, to expose the source over only a limited circumferential angle. A modified arrangement for withdrawing cylinder 2 from the closed position of Fig. 4a includes a rod 3, with attached collars 27 and 29, slidable within a collar 28 attached to the cylinder 2. Movement of rod 3 to the right initiates the operation of a timer, and compresses springs 21 and 22 until the rod is retained in position by the movement of collar 27 beneath the latch 24, Fig. 4b. At a time determined by the timer the solenoid 25 is energized to raise the latch 23, whereupon cylinder 2 is urged to the right into the expose position (Fig. 4c, not shown) under the action of the spring 21, which initiates the operation of a second timer to cause the energization, after a predetermined interval, of the solenoid 26, to raise latch 24 and permit cylinder 2 to return to the closed position under the action of the spring 22. The use of hemispherical shielding bodies instead of cylinders 1 and 2 is referred to.
