Patent GB-1111391-A (GB)
Title: Solid propellants
IPC: B01F13/10
Filed: 1962-10-26
Abstract: Solid propellant is made by a continuous process in which a stream of resin binder is introduced into a moving stream of an oxidizing material, followed by mixing to obtain a uniform composition.  The process prevents pressure build-up and short-circuiting of the resin, and reduces the danger of explosion.  As shown in Fig. 1, the solid oxidizer is fed at a controlled rate from hopper 14 to screw conveyer 18 and mixer 26; the oxidizer may be recycled in a fluidized state via line 22. The mixer comprises a rotating screw-bladed shaft and stationary teeth 28.  Components reacting to form a polyurethane binder are introduced into the mixer through inlet 30, the isocyanate ingredient from tank 32 which is at low pressure, and a slurry of additives in the polyol ingredient from vessel 38 in which an inert atmosphere is maintained.  The inlet 30 extends into the stream of oxidizer and is constructed as shown in Fig. 4. The isocyanate feed enters at 105 and flows through tube 106; the polyol slurry enters at 112 and flows through annular space 114 around the tube 106 and so surrounds the isocyanate stream on introduction through inlet 30 into the mixer.  A radioactive tracer may be added at 111, so that tests may be carried out to determine the efficiency of the mixing.  The mixed propellant passes from the mixer through <PICT:1111391/C1/1> <PICT:1111391/C1/2> pipe 63, Fig. 1, to cooled deaerator 68 which is connected to a source of vacuum.  The mixture is then tested in instrumentation section 80 and either passed to waste or to the curing section, for example being discharged directly into a rocket casing and cured in situ.  Compositions.-Suitable compositions containing polyurethane are described in Specification 984,960.  The Specification includes lists of suitable isocyanates, isothiocynates, hydroxy and thiol compounds, and cross-linking agents; preferably the isocyanate component is used in slight excess over the hydroxy or thiol component. The binder may also be asphalt, or polyester or other resins as described in Specifications 579,057 and 883,586 and United States Specification 2,563,265.  Suitable oxidizing agents are chromates, dichromates, permanganates, nitrates, chlorates, and perchlorates of alkali or alkaline earth metals, ammonia, hydrazine, or guanidine.  Aluminium powder may be included in the composition. Other standard additives specified are plasticizers, catalysts, burning rate modifiers, antioxidants, wetting agents, and antifoaming agents.  A suitable igniter for the propellants is described in United States Specification 3,000,312.

Abstract: 961,607. Shifting sheets. BAU-STAHLGEWEBE G.m.b.H. Nov. 14, 1961 [Dec. 6, 1960], No. 40734/61. Heading B3M. [Also in Division B6] Welded structural steel mesh reinforcements are delivered from a welding machine on to a table 1 and are then lifted manually from the table and formed into a stack. Like sides of the reinforcements are placed adjacent to each other in the stack so that the maximum number of reinforcements may be stacked in a given height and to facilitate this alternate reinforcements delivered to the table 1 are inverted by arms 3 mounted on a rotatable shaft 4 and normally resting in grooves in the table. The shaft 4 is rotated, by power or by hand, through about 100 degrees in order to raise a reinforcement off the table 1 and bring it into engagement with an inclined wall 5 connected to the table; the shaft is then rotated in the opposite direction and as the arms 3 reach their rest position the reinforcement slides down from the wall 5 back on to the table 1 in an inverted position. The inverted reinforcement is prevented from over-shooting the table by an abutment strip 8 secured thereto. If the turning device is power-driven its operation may be automatic and controlled hydraulically, electromagnetically, pneumatically or electronically.

A second electrode spacedly juxtaposed with the first electrode is immersed in the bath of sludge. When electric potential is applied across the electrodes, water flows from the sludge through the surface perforations and a consolidated sludge deposit is formed on the surface of the displaceable electrode. Downstream from the bath, means are provided for removing the sludge from the surface of the displaceable electrode. In one form of the apparatus sludge is introduced via conduit 1 to vessel 2 forming a bath 2a. The bath contains a stationary electrode 3 and the second displaceable perforated electrode 4 passes along the path shown via the rollers 5a-5e. An electric potential source 6 is connected to electrodes 3 and 4, the latter via 5b. Sludge d is deposited on the electrode 4 reducing the water content to 90- 96% and the separated water is drained to tank 12. The deposited sludge passes to a heat chamber 7 in which a hot air current reduces the water content of the sludge to about 60%. The dried sludge is then subjected to an air blast from nozzle 9 and to a scraping action from the rotary brush 10. The sludge removed is collected in receptacle 11. Preferred embodiments include an incinerator downstream from the heating chamber, means for controlling both the thickness and water content of the deposited sludge and means for providing a porous film of non-conductive material on the belt. The recovered sludge may be used for fertilizer, fuel or as raw material for producing activated carbon.

Title: A separately controlled inverter
IPC: H02M7/53862

Abstract: 940,597. Transistor oscillators. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. Nov. 17, 1961 [Nov. 25, 1960], No. 41239/61. Addition to 931,322. Heading H3T. [Also in Division H2] A main inverter controlled by a self-excited inverter whose D.C. circuit includes a controlled semi-conductor device, such as a transistor p3, which is made conducting by a rectified portion of the main inverter output according to the parent Specification has an additional circuit including capacitor k4 and at least one amplifying member, such as p8, p9, p10, arranged so that the first mentioned controlled semi-conductor device is made to conduct briefly when the D.C. supply 20, 21 is switched on, so as to make unnecessary the starting push-button of the main patent. The main inverter comprises parallel operated transistors p4, p5 and p6, p7 and the centre-tapped primary winding of transformer t2 whose secondary supplies load circuits 3, 4, 5, 6, 7, such as fluorescent lamp p23, through an antiresonant circuit having capacitor k1 and inductances d1, d2 to improve the output waveform and through thermistor r21 which damps the starting current through the compensating capacitors such as k7. The self-excited inverter comprises transistors p1 and p2, and the centre-tapped primary of transformer t1 whose secondaries supply the control signals for the main inverter. Both inverters are supplied from a common D.C. source, the self-excited inverter being supplied through transistor p3. The frequency is determined by the ganged variable resistors r22, r23, and variable resistor r24, r26, r27 permit the half-waves to be made symmetrical. The network of elements N6, k5, r8 and the network N5, k3, r9, whose components are not necessarily of the same values, serve to reduce excess voltages at the transistors pl and p2. When transistor p9 is conducting p10 is blocked, and consequently transistor p3 conducts. The transformer t3 and bridge rectifier make transistor p9 conduct when there is a voltage between the output conductors 1, 2. Transistor p8 normally conducts and therefore tends to block transistor p9 and hence transistor p3, but when the inverter is first switched on the charging of capacitor k4 causes blocking of transistors p8, and hence transistors p9 and p3 become conducting, so starting the inverter.

Abstract: 1,076,035. Extrusion / blow - moulding. M. A. J. VERLINDEN. Oct. 9, 1964 [Oct. 10, 1963], No. 41330/64. Heading B5A. [Also in Division B8] A plastics barrel (see Division B8) is formed by moulding, e.g. blowing, a spherical portion from an extruded parison 62<SP>1</SP> and bonding the spherical portion to end members 2 already located in the mould. Polyethylene particles are fed from a hopper (13), Fig. 6, by a screw conveyer (11) between grooves (17), Fig. 6A, in a valve head (16) to fill a duct (14), a bore (19<SP>1</SP>) and a space (24) surrounding the rod of a thickness controller in the form of a piston (26). A stroke regulator (32), operated hydraulically, pneumatically or by means of an eccentric plate, controls the piston (26) during extrusion to vary the thickness of the parison. Increased thickness of the parison wall (at 62<SP>2</SP>), Fig. 8, causes the wall of the moulded barrel to be uniform. The die, formed of two movable halves 33, 34 co-operates with an extrusion head (28). The plastics material, heated by a member (C), is extruded under pressure from a piston (22) which also causes the valve head (16) to close against a seating (16<SP>2</SP>), Fig. 6A. Each half 33, 34 of the die has a movable ring 40, 41 respectively, which holds the respective end member 2 in place. A plug 46, formed with a cone 48, and a plug 51 carrying a pipe 49 form bung-holes, the pipe 49 being connected to a source of compressed air. After extrusion of the parison, the die halves are moved together, edges 63 on the rings 40, 41 cutting off the plastics material. The spherical portion of the barrel is then blown into contact with the die and end members 2 by means of the pipe 49. Alternatively, the spherical portion of the barrel may be formed by injection, casting or centrifuging, the end members 2 being subsequently united thereto. In a modification, the barrel may be formed of glass-fibre reinforced polyester by the following steps. Glass-fibre reinforcing elements are pre-formed by spraying the fibres, with resin, into a rotary mould having a suction wall to hold the fibres in place. These elements are then introduced with polyester resin into a hydraulically operated mould to form the main parts of the barrel. After compression, the parts are cured in an oven before being bonded together. The joint may be further reinforced externally by glass-fibre polyester.
