Title: Process for densifying nitrocellulose
Inventor: SAPIEGO JOHN JAMES
IPC: C08B5/04
Filed: 1967-01-11
Abstract: 1,137,653. Densified particulate nitrocellulose. HERCULES Inc. 11 Jan., 1967, No. 1628/67. Heading C3A. Densified, finely-particulate nitrocellulose is made by (a) forming a slurry substantially free of fibre aggregates by agitation of fibrous nitrocellulose which is substantially water-free in a mixture of a hydrocarbon diluent and an organic nitrocellulose solvent which is soluble in the diluent to the extent of at least 2À5% by weight, said mixture being capable of softening but not dissolving the fibres, (b) subjecting the slurry to shear agitation whereby the fibres are softened and swollen and break down into particles, (c) initiating hardening of the particles by diluting the slurry with a hydrocarbon diluent while continuing the shear agitation, and (d) removing substantially all of the solvent by distillation in the presence of excess hydrocarbon diluent to complete the densification and hardening. In one embodiment high shear agitation is used to produce particles in the size range 15-150Á and a density of 1À58-1À62 g/c.c.; in another embodiment a water-soluble protective colloid (preferably 0À1-0À2%) is added at stage (b), mild shearing agitation is used, and the final particle size is 150-600Á with a density of 1À3- 1À38 g/c.c. Heptane is the preferred hydrocarbon using methyl ethyl ketone or acetone as solvent, and gum arabic or methyl cellulose as colloid. Long lists of alternatives are given. The starting nitrocellulose is preferably subjected to a fibre-beating step before step (a) and may have an N-content of 10À9-13À5%.

Abstract: 1,260,142. Sound activated doll. HALAS & BATCHELOR ANIMATION Ltd. 8 Jan., 1969 [11 Jan., 1968], No. 1648/68. Heading A6S. A dolls head 11 has lips 12 and 13 which are movable and linked to an electromechanical transducer such that the extent of movement of the lips is proportional to the amplitude of an electric signal derived from a sound effect. Lip 12 is linked to a lever arm 14 by a peg 15 and a strip 16. The lever arm is pivoted at 17 on a rod secured in the head, and is biased by spring 18 towards a position in which the lip is in the closed position. A wire 19 connects the lever arm to the armature 21 of a solenoid 22. Lip 13 is connected through a double lever arrangement to solenoid armature 32 so that its direction of movement is opposed to that of lip 12. Eyes 53 are connected, as a pair to solenoid 46 by a linkage similar to that described above. Fig. 2 (not illustrated) shows the electronic arrangement by which a sound effect is used to activate the solenoids 22, 23 and 46 as well as being branched at 37 to supply speaker 39 via audio amplifier 38. The solenoid activating circuit is divided in turn into three branches 42, 43, and 44 after being fed through audioamplifier 41. The electrical signal in channel 42 is rectified by diode D1 and the output fed to an output amplifier 45 via averaging network 57, which serves to eliminate continual lip-quivering, and finally the output from this amplifier is applied across solenoid 22. Channel 44 has an identical circuit arrangement and activates solenoid 33. Channel 43 which activates the eyes via solenoid 46 is identical to those of 42 and 44 except that the averaging circuit is arranged to scan over a wider range of frequencies than in the other cases causing the eyes to move slowly to a central position while speech is being received and to move slowly to one side when speech dies away Figs. 3 (not illustrated) shows a modification in which a light sensitive resistor 48 replaces the diode rectifier and averaging circuit, Fig. 4 (not illustrated) a modification in which audio signals are carried on a 50KHz signal from an oscillator or Fig. 5 (not illustrated) a modification to use Bowden cables for actuating solenoids when the head is small.

Title: Improvements in or relating to word printing apparatus
IPC: B41J7/90
Filed: 1956-01-18
Abstract: 807,311. Typewriters &c. HANDLEY, J. Jan. 17, 1957 [Jan. 18, 1956], No. 1653/56. Class 100(4) A key-operated word printing typewriter which rapidly prints in succession the letters of the "word" or phrase selected has a rotating cam which completes electrical circuits to the required characters and a clutch for driving the cam from a continuously rotating shaft. Cam 28 on continuously rotating shaft 29 closes contacts 4. When a key is depressed, a circuit is completed through 2, 3, 4, 5, 30. Armature 31, moved by clutch magnet 5, releases pawl 33 which engages 37 so that cam 6 on shaft 35 rotates with wheel 37 which is itself driven from shaft 29 through 39, 40, 38. Armature 31 also closes contacts 9 to energize check magnet 8 which remains energised through holding contacts 27 as long as a key 1 is held depressed. Lock bar 10 is moved in behind bar 42 of armature 31 by 45 and armature 44 which moves up to magnet 8. By this time magnet 5 will be de-energized as contacts 4 will be open again. Cam 6 can thus make one revolution only however long a key is held depressed since 10 prevents 31 from releasing pawl 33. When key 1 is released armature 44 is spring- returned to rest. When a relay 3 operates, its eight contacts 11-18 all close. Contacts 11 are hold-contacts for relay 3 through contacts 19 which close when cam 6 revolves. Contacts 12-18 are connected to contacts 20-26 and through 7 to relays associated with the letters of the word to be printed. Contacts 20-26 are closed in succession as cam 6 rotates and corresponding letters are printed in the order required. Specifications 789,742, 791,432 [Group XL(a)] and 798,093 are referred to.

Title: Apparatus for treating sugar solutions and other liquids
IPC: C13B20/14
Filed: 1966-01-13
Abstract: 1,139,692. Purifying sugar. BRAUNSCHWEIGISCHE MASCHINENBAUANSTALT. Jan.13, 1966 [Jan.15, 1965], No. 1714/66. Heading C6B. [Also in Division B1] In a continuous process for purifying sugar solutions (or other solutions) in which the steps of sugar purifying, washing and regenerating are being carried out concurrently, the cells containing the impurity-removing material (i. e. absorbent, adsorbent or ion-exchange material) are cyclically treated with sugar solution, washing liquid, regenerating solution and washing liquid. The cells may be drained between the liquid treating steps. In one embodiment a suitable apparatus comprises two circular rows of anionic (A, A1 &c.) and cationic (K, K1 &c.) exchangers. The exchangers are connected in groups and at any one time each group has a fluid (e. g. sugar solution, washing liquid) passing through it. Beneath the exchanger are two circular channels 2, 5 divided into compartments 3, 4 and 14, 15 respectively to correspond with the number of exchangers. Channel 2 is movable. Sugar solution is supplied by feed line 22 which is movable along with channel 2. Solution from line 22 is passed into a compartment 14 where it is mixed with sugar solution draining from exchanger A, K. From compartment 14 the solution is pumped by pump 11 via line 23 to exchanger K1 from where it overflows via pipe 17 into compartment 3 and thence to a compartment 14. The sugar solution is then similarly and successively pumped through exchangers K2 &c. When it is passed through the last cationic exchanger of the group receiving the sugar solution it is directed via a compartment 3 and line 24 to a compartment 15 from where it is pumped by pump 7 to exchanger A1. The solution is successively pumped through the anionic exchangers in the group in a way similar to its passage through the cationic exchangers. The sugar solution from the last anionic exchanger is discharged via a conduit connected to channel 2 to a collecting tank. Simultaneously the other liquids e. g. (regenerating and washing liquids) are passed in a similar manner through their respective groups. After a period of time channel 2 and feed line 22 are moved such that exchangers A1, K1 are now in the drainage position and valves 20, 21 (e. g. solenoid operated valves) are opened and exchangers A, K are now part of the group of exchangers receiving the washing liquid. Simultaneously the composition of the other groups have changed in a similar way. The channel 2 and feed line 22 are moved intermittently such that the exchangers are cyclically treated with the different fluids and the process is continuous.

Title: Improvements in or relating to fluid fuel injectors
IPC: F02M67/12
Filed: 1936-01-20
Abstract: 469,182. Fuel injectors. OFFEN, A. Jan. 20, 1936, Nos. 1774 and 9918. [Class 7 (iii)] [Also in Group XXVI] A fuel injector more particularly for introducing fuel into a gas turbine such as described in Specifications 445,550 and 469,180, [both in Group XXVI], comprises one or more jets and a pressure controlled flap valve co-operating with each jet to produce a centrifugal discharge from each jet and to regulate the delivery according to the change of pressure of the fuel supply. Fig. 1 shows an injector in which fluid supplied through a pipe 30 passes through holes 16 parallel to the axis and impinges against a valve 18 provided with spring tongues 37 as shown in the lower part of Fig. 5. These tongues are opened by the pressure of the fuel, and give a whirl to the escaping fiuid. Fig. 6 shows a form in which air passing through the central tube 22 is whirled by a helical strip 23 and escapes through an opening 27. Fuel, admitted through a pipe 30, passes to a chamber closed by a disc 25 having peripheral inclined slots 35, Fig. 5, which in conjunction with the tongues 37 on the valve 18 give a whirl to the fuel. Fig. 7 shows an injector provided with a regulator for cutting off the fuel supply under predetermined conditions. The air supply tube 22 is formed as a double seated valve which in the position shown closes ports leading to a passage 56. On pressure rising in a pipe 46 leading, e.g. from a compressor driven by the turbine, the rod 47 rises, causing the lever 50 to snap over and lower the tube 22, closing the outlet 28 and connecting the fuel supply 30 to the byepass 56. Immediately the pressure in the pipe 46 falls the tube 22 is raised and atomized fuel is again delivered.

Apparatus for slitting a plastics sheet wound on a spool 55, Fig. 1, into a number of strips, e.g. as recording tape, which is drawn off on to take-up spools 119 comprises a cutter head 52 in which cutters 51, Fig. 2, e.g. razor blades, are clamped together between plates 29 ... 31, Fig. 6, the head being secured to a swinging arm 60 and driven by a motor via an eccentric and connecting rod. A co-operating grooved roller 53 is mounted in bearings on an eccentrically displaced shaft 39 secured on a swinging arm 2, so that it may move backwards and forwards in an arc, and is swung in, by a lever 44, for cutting to commence. A lever 7 effects the cutting movement of the grooved roller, and a lever 12 the swinging movement of the cutter 54 head, the levers being controlled by a disc 14 carrying push-rods 15, 16 in a double eccentric arrangement, driven by a pulley 21. The oscillations of the grooved roller are 90 degrees out of phase with those of the cutter head, so that the cutters in operation move in an endless curve in continuous relative movement with respect to the sheet being slit, so that the point of cutting on the cutting edge is continuously being changed. The take-up apparatus for the spools 119 comprises a hollow shaft 121, Fig. 5, and a main shaft 101 arranged so that when the thickness of the tape to be severed is constant the shafts run at the same speed, but may be compensated for different thicknesses of tape by changing the speed. Both shafts are driven by a pulley 101 via clutches 108a, 108b by belt drive from a variable-speed motor. Up to four tapes may be wound simultaneously on each shaft. The tape is cleaned before being wound up, by duster rollers, blowing or suction.

Title: Improvements relating to the operation of gas producers
Inventor: BURKE SHULDAM ARCHIBALD
IPC: C10J3/72
Filed: 1951-01-24
Abstract: 702,917. Regulating fuel supply to gas producers. C.U.R.A. PATENTS, Ltd, and KENT, Ltd., G. April 17, 1952 [Jan. 24, 1951], No. 1883/51. Class 51 (2). [Also in Group XXIX] In a gas producer, the temperature of the producer gas is maintained at a desired value-by regulation of the coal feed, the latter being subject to an automatic system under the control of a plurality of variables including the producer gas temperature and a producer load signal. An indication of the load on the producer is given by the rate of flow of the air blast to the producer or of the gas flow, the pressure drop across the fuel bed, the steam flow or pressure in the case of steam blown producers, the steam flow or fan speed in the case of steam turbine-driven air fans, or by the power or current consumption or motor speed in the case of electrically driven fans. In an embodiment, the signal from a thermocouple 18, Fig. 1, in the producer outlet is applied to a measuring instrument to operate a pneumatic controller and produce a pressure which is applied to a bellows 8. Movement of the bellows is transmitted through a bell crank 9 to one end of a floating lever 6. The flow of air in the blast main 3 leading to the producer is measured by means of an orifice plate and a meter 5, and the indication so obtained is applied to the other end of the floating lever 6. The latter is connected through an adjustable link 11 to a flapper 12 controlling the leak of air from a nozzle 13 fed from a pressure supply through a resistance 15, and the resultant pressure upstream of the nozzle is applied through an amplifier 17 and a line 20 to the coal feed regulator 21 of the producer. This amplified pressure is also applied to one side of the bellows 8 to bring it back to its neutral position. In a modification, the air pressure obtained from the temperature signal is applied only to a bellows which varies the position taken up by link 11 along the floating lever. The temperature indication may be applied direct to the floating lever and the signal corresponding to the air flow is then applied to the bellows. The rate of coal feed is proportional to the load, and a temporary variation in this proportional factor is obtained by inserting a variable resistance in the line leading from the amplifier to the bellows and connecting the inside and outside, respectively, of a further bellows to the ends of the resistance. A similar result is obtained by inserting the device shown in Fig. 4 into the pressure line 20. The pressure from amplifier 17 is fed directly into chambers A, C and through a variable resistance R into a chamber B1 the various chambers being defined by diaphragms a ... f of varying area connected to a central core. Movement of the latter actuates a valve controlling an independent, regulated, air supply 28, and the control pressure so obtained is taken off as the output pressure to line 20a.
