Title: Improvements in the manufacture of rocket motors
Inventor: BRYANT ROBERT WILLIAM
IPC: F02K9/34
Filed: 1963-07-22
Abstract: 1,084,995. Rocket motors. MINISTER OF TECHNOLOGY. Oct.22, 1964 [July 22, 1963], No. 28870/63. Heading F3A. In a rocket motor having a casing lined with e.g. phenolic resin containing asbestos or chlorosulphonated polyethylene, failure of the bonding to the propellant charge, comprising a polyurethane or polybutadiene binder, is prevented by facing the inner surface of the lining material with a layer of metal foil, e.g. tin, copper, or aluminium having a thickness between 2 and 5 thousandths of an inch and bonded to the lining with synthetic rubber resin, e.g. neoprene based adhesive, and casting the propellant charge directly in contact with the foil. The surfaces of the foil and lining material to be bonded are degreased with ethyl methyl ketone and, after brushing the adhesive on to both surfaces, the foil is applied in pieces with the edges overlapping and excess adhesive wiped from the surface thereof and the foil pressed into contact by an inflated pressure bag.

Filed: 1975-08-21
Abstract: 1517161 Implantable bone clamps M R V RAGHAVA 21 Aug 1975 [29 June 1974] 28985/74 Heading A5R [Also in Division E2] An implantable apparatus for use in repairing bone fractures comprises a rigid bar 18 and spaced clamps 20 which grip the bone on each side of the fracture. The bar is of a metal suitable for implantation and has apertures 30 which accommodate threaded shanks of claws 24. This apparatus is implanted about the fractured bone and second claws 26 are screwed onto the shank so claws 24 and 26 fit within recesses 34 in bar 22 and thus are prevented from pivoting about the shanks. A locking device in the form of a strip fixed between bar 22 and claw 26 and bent over to abut nut 32 may be used. The claws may have different shapes such as a crossed shape for use with various fractures and have a knurled or roughened surface 36.

Title: Aerobic biological treatment of wastewater
IPC: B03D3/00
Filed: 1975-07-10
Abstract: A solids-liquid mixture, such as waste water, containing biologically degradable material is treated in a circulatory system having alternating upward and downward flow kept in motion by injection of gas such as air. Mixture is diverted from the system into a separating chamber in which solids-enriched mixture is separated by flotation and/or sedimentation. A solids-rich mixture, preferably recycled from the separation chamber, is fed into the system hydrostatically and thereby the concentration of such solids in the system is maintained and/or such solids are transferred from one location to another without mechanical pumping.

Title: Production of sulfur dioxide
IPC: C01B17/60
Filed: 1969-06-09
Abstract: 1275266 Sulphur dioxide CHEMICAL CONSTRUCTION CORP 9 June 1969 [14 June 1968] 29160/70 Heading C1A Sulphur dioxide is removed from waste gas streams by scrubbing with an aqueous magnesium sulphite solution, a part of the scrubbing solution being subsequently treated with Mg(OH) 2  to convert Mg(HSO 3 ) 2  to MgSO 3  and then recycled to the scrubbing stage, and a second part being treated for the production of MgO with liberation of SO 2  which can be further processed. In the embodiment illustrated in Fig. 1 gas stream 4 is contacted with aqueous MgSO 3  in scrubber 5 and the outlet stream 9, which contains some Mg(HSO 3 ) 2  is filtered, 10, and divided into two streams 13 and 14. Stream 13 is treated with Mg(OH) 2  from slaker 27 to convert Mg(HSO 3 ) 2  to MgSO 3  and this solution is then recycled to scrubber 5. Stream 14 is treated in reactor 15 with MgO from calciner 21 to convert Mg(HSO 3 ) 2  to MgSO 3  which is filtered (18), the solid MgSO 3  being calcined (21) and the liquor being returned to the scrubber 5. The MgO produced in calciner 21 is partly used in reactor 15 and partly is slaked (27) and the Mg(OH) 2  produced used to convert Mg(HSO 3 ) 2  to MgSO 3  in the feed to scrubber 5. The gas stream leaving calciner 21 contains a high proportion of SO 2  and can be converted to useful sulphur products such as liquid SO 2 , H 2 SO 4 , and elemental sulphur. In the embodiment of Fig. 2, that portion of the outlet liquor from scrubber 5 which is not recycled to the scrubber, is filtered (41) and the liquor, which contains MgSO 3  and Mg(HSO 3 ) 2  is concentrated in evaporator 44 to produce a slurry which is passed into a fluidized bed of MgO maintained in chamber 48 where conversion of Mg(HSO 3 ) 2  to MgSO 3  and the calcination of MgSO 3  occur to produce MgO, some of which is led off to slaker 59 as before described. The SO 2  containing gas stream 51 leaving chamber 48 is cooled in heat exchanger 52, where it heats the inlet air stream which maintains the fluidized bed in chamber 48, and can then be converted into useful sulphur products such as liquid SO 2 , H 2 SO 4 , or elemental sulphur.

Filed: 1930-10-02
Abstract: Soft fruits such as raspberries and blackberries are desiccated by first adding pectin to the amount of 0,25-9 per cent of the weight of the fruit and then drying, e.g. by means of hot air. The pectin may be added in the form of pectin extract, or of apple pulp mixed with a proportion of skin, or a quantity of the enzyme pectase sufficient to produce the pectin required from material already present in the fruit may be added.  The fruit is pulped and may be deprived of its pips, seeds, stones, stalks, and other unrequired parts before drying.  The fruit may be subjected to the drying in the form of spray or of pressure extruded streams.

Abstract: 997,461. Expanding wheel gears. W. REIMERS. July 26, 1963 [July 31, 1962], No. 29710/63. Heading F2D. A belt or chain tensioning torque responsive axial force on the flanges 8, 10 of an expanding pulley is varied with effective pulley diameter by dividing the driving torque into two components, the magnitude of which varies with pulley diameter and one of which acts directly on one flange whilst the other acts through an axial force-producing ball 7 between cam surfaces, on the same as the other flange. The driving torque is divided into two components by a pin 2 which engages a rocking rod 4 at a point which varies with pulley diameter. As shown, the pin 2 is fast with a shaft 1 and carries a roller 3 which engages parallel rocking rods 4 pivoted to a sleeve 5 connected by pins 14 to the flange 8 and to a ring 6 of the axial forceproducing means 7. Axial movement of the flanges 8, 10 controlled by levers 13, 18 for ratio shift is accompanied by axial movement of the sleeve 5 and rocking rods 4 to change the point of contact between the rods 2, 4 and thus the magnitude of the torque component through the force-producing means 7. In Fig. 2 (not shown), the rocking rods are arranged radially between a sleeve integral with one pulley flange and a sleeve on which the cam surfaces are formed, whilst the pins 2 are fast with a ring secured to the shaft 1 and are arranged in pairs at an oblique angle to the axes of the shaft with the rocking rods therebetween. In Fig. 3 (not shown), the rooking rods are pivoted in a ring and the outer end of the sleeve 5 and the balls 7 are interposed between cam surfaces on the ring and sleeve 5. The axial force produced is transmitted through the rocking rods and a bearing to the pulley flange. In Figs. 4 (not shown), only one flange is axially movable for ratio shift and an extension thereof carries the pin 2 which engages a rocking rod pivoted between a ring fast with the shaft 1 and a ring 6 which acts through balls 7 on the other flange. In Fig. 5 (not shown) only one flange is axially movable for ratio shift and an extension thereof carries a curved rod 2 which engages a radial rocking rod pivoted between the shaft 1 and a sleeve formed with cam surfaces which cooperate with the ball 7.
