Abstract: 1288122 Fertilizers from polysaccharidecontaining materials AMERICAN REFINING Ltd 20 Jan 1970 [31 Jan 1969 24 June 1969] 2696/70 Heading C1B [Also in Division C6] A controlled decomposition of polysaccharidecontaining organic materials is achieved by contacting the organic material in an inanimate environment with a symbiotic mixture of microflora capable of metabolizing cellulose, e.g. Cellulomonas and sufficient protozoa capable of feeding on both the cellulose-metabolizing microflora and putrefactive micro-organisms to maintain a stable population of the cellulosemetabolizing microflora, in an amount sufficient to cause decomposition of the organic material and under conditions favouring the growth of the cellulose-metabolizing microflora. The product may be applied as a liquid fertilizer. The symbiotic mixture may comprise the undigested contents of the intestines, rumen or caecum of insects and mammals (specified). Mushroom tissue may be included to promote the decomposition of proteinaceous material autolytically rather than putrefactively. An exemplifying procedure involves fermenting with the symbiotic mixture in an air-tight concrete pit a mixture comprising cereal grain, corn stalks, sorghum cane, wood waste, inorganic mineral supplements, manures, vegetable waste and fish meal. A reactor comprising a hoppershaped chamber provided with mechanical bellows in its side walls may be employed when faster production of the break-down products is desired. Examples are directed to the fermentation of orange, grapefruit or banana peels, peanut shells, pine wood, milk, urine and faecal material. Specification 1,281,111 is referred to.

Title: Improvements in or relating to liquid pressure remote control systems, more particularly for operating soot blowers of boilers and the like
IPC: F28G15/00
Filed: 1940-02-16
Abstract: 538,880. Fluid-pressure soot-blowers &c. AUTOMOTIVE PRODUCTS CO., Ltd., and EVES. F. S. Feb. 16, 1940,No. 2938. [Class 99 (ii)] [Also in Group XXIX] A liquid-pressure remote control system, particularly for soot-blowers, comprises a double-acting fluid-motor unit 19 connected with a reversing-valve 13 by a pair of interchangeable supply and return pipe-lines 15, 16, the reversing valve being actuated by pressure-liquid fed thereto through a shunt pipe-line 38 under the control of the unit 19. Valve-reversal is effected when the shunt-conveyed fluid acts through passages in the valve on the piston 42 of a double-acting auxiliary motor. A quickthrow of the valve is obtained by the snap-over action of the linkage shown to the left of Fig. 1. The valve-stem 70 is hollow and formed with radial and peripheral channels controlling not only the action of the shunt 38 and motor 42, but the supply and circulation of pressureliquid from the pump 10 and reservoir 11 to the flow and return pipes 15, 16. Pressure is set up in the shunt 38 when the double-acting piston 24, 25 engages one of the pins 32, 33 and opens the corresponding ball valve 30, 31, further ball-valves 34, 35 also being fitted to prevent neutralizing action through the pipe 32. In a modification intended for soot-blowers of the non-retractable type, the drive is through ratchet-gearing which occurs during the movement to the right of the pistons 24, 25. Each piston is moreover provided with a resilient face for engaging the pins 32, 33, producing a quicker opening of the associated ball-valves. In a soot-blower of the retractable type, Figs. 3 and 4, the nozzle-shaft 140 is actuated through a screw-and-nut gearing from a gear wheel 155. A double-acting unit 166 of the general type described above oscillates a pinion 169, axially and obliquely bored to receive rods 76, 179, the latter of which penetrates into a recess on the hub of the wheel 155. Dowels 186, designed to shear under excessive torque, such as that occasioned by jamming of the blower nozzle, are also lodged in the adjacent end faces of the wheel 155 and shaft 168. Such shearing dislodges the rod 179 and moves the rod 177 axially to push aside the support for the roller 201. The valve 194 in the pressure feed-line 18S, 188a is then closed by the spring 196 and the unit 166 is brought to a standstill. Reciprocation of the double-acting piston is in this construction effected by mechanism comprising a gear 218 integral with a drum 221 the surface of which is grooved as a cam to be engaged by a spring-pressed finger 223. Tilting of the finger about its pivot 224 moves the roller 233 and opens one or other of the valves 29, 30, bringing into use the shunt 38. The cam groove provides for both long and short nozzle strokes, and is stepped at the junctions to ensure unidirectional travel of the pin 222. Specifications 538,881 and 538,882 are referred to.

Vehicle washing apparatus comprises a horizontal rotary brush 12 for cleaning the roof of a vehicle 15 and a set 13a of vertical brushes 13 for washing the sides of the vehicle 15, the apparatus also including either an additional horizontal brush disposed so that the vertical brushes are between vertical planes through the rotational axes of the horizontally disposed brushes, or, as shown, an additional set 13b of vertical brushes 13 disposed on the opposite side of a vertical plane through the rotational axis of the horizontal brush 12 to the set of brushes 13a. The brushes 12, 13 are supported on a gantry 11 movable on rails 16 along the length of the vehicle 15 and the vertical brushes 13 are fitted to the gantry by pairs of pivotal arms 14 one at the top and one at the bottom of each brush 13. The brushes 13 are held against the vehicle with a predetermined pressure but during a pass of the gantry 11 along the vehicle 15 to the right of Fig. 1 means are provided for holding the set of brushes 13a away from the vehicle and during a pass to the left for holding the set of brushes 13b away from the vehicle 15 or alternatively, in the arrangement comprising an additional horizontal brush, means are provided for holding that horizontal brush which is in advance of the set in the direction of movement of the brushes relative to the vehicle away from the vehicle. The pivotal arms 14 associated with the set 13a or 13b cause the brushes of the set to maintain contact with vehicle 15 to clean the ends thereof until the arms 14 are at right angles to the direction of gantry movement when further gantry movement separates the brakes 13 from the vehicle. In the embodiment of Fig. 2 (not shown) the pivotal axes (17a) of the pivot arms of a set of vertical brushes 13a or 13b are off-set relative to each other along the vehicle. In the modification of Fig. 4 and Fig. 5 (not shown) an auxiliary vertically disposed brush 21 is fitted between each pair of upper and lower pivot arms 14 intermediate the pivotal axis of the pivot arms 14 and the axis of the vertically disposed rotary brush 13 associated therewith. Each auxiliary brush 21 is of smaller height than its associated vertical brush 13 and rotates in the opposite direction thereto i.e. in the same direction as the movement of the gantry 11.

Abstract: 1362902 Nuclear power plant; cooling reactors GES ZUR FORDERUNG DER FORSCHUNG AN DER EIOG TECHN HOCHSCHULE 21 Jan 1972 [25 Jan 1971] 3029/72 Heading G6C Following a nuclear reactor emergency trip, after-heat is removed by opening a by-pass line across a coolant-driven turbine so as to increase the flow of coolant through the reactor. In the nuclear power plant embodied in Fig. 1, the reactor is cooled by gas passing through three circuits in parallel, only one being shown in full. Hot gas passes, in each circuit, through a high pressure turbine 6 driving compressors 10, 12 and a generator 19, thence through heat exchangers 8, 9 to low pressure compressor 10, heat exchanger 11, high pressure compressor 12, heat exchanger 8, then back to the reactor. Following rupture, as at 30, in one circuit, a pressure gauge 17 initiates the emergency trip and causes a by-pass valve 16 across turbine 6 to open. The valve 16 is also controlled from a speed governor 20 on the compressor drive shaft 4. A further by-pass valve 24 is controlled in dependence upon the inlet/outlet pressure across the compressor 12, and another by-pass valve 27 is controlled in dependence upon measurements from a temperature gauge 28. These valves are opened successively to ensure effective heat removal from the reactor. A pony motor 22 can be energized to maintain or increase the speed of shaft 4. In a second embodiment (Fig. 2, not shown), the single turbine is replaced by a low pressure turbine (62) which drives the generator by way of a governor-controlled shaft (42), and a high pressure turbine (61) having a common drive shaft with the compressors. The reactor pressure gauge controls a by-pass valve (161) across the low pressure turbine, while the by-pass valve (162) across both turbines is controlled from the governor (202) of the compressor drive shaft. The reactor is of the fast breeder type.
