Title: Apparatus for the winding of roller-driven cross-wound bobbins
IPC: B65H54/74
Filed: 1964-03-04
Abstract: 1,010,755. Winding roller-driven crosswound bobbins. ALGEMENE KUNSTZYDE UNIE, N. V. March 4, 1964 [March 7, 1963], No. 9094/64 Heading D1J. The invention relates to winding machine in which a package 3 Fig. 1 is in contact with a driving drum 1 and in which the thread is traversed by a grooved traverse drum 5. The object of the invention is to rotate the traverse drum 5 at a speed that is not in constant relationship with that of the drive drum 1 and in which the traverse drum 5 derives its rotation directly from the driving drum 1 without relying on frictional forces between the package 3 and the drum 1. In Figs 1 and 2 the package 3 is mounted on an arm 8 that swings about the axis 6 of the traverse drum 5 as the package 3 increases in diameter. Mounted freely on the shaft 4, of the package 3, is a pulley 9 bearing against the side of the drive drum 1 on the line where it engages the package 3. As the package 3 increases in diameter the shaft 4 moves away from the driving drum 1 and the resulting increase in the radial setting of the drive point on the pulley 9 slows down the speed of rotation fo the pulley 9. The pulley 9 has a hollow hub having teeth 11 that engage a timing belt driving a pulley 13 coupled to the traverse drum 5. Fig. 4 shows a cross-section through a pulley 9, the hollow-hub 10 containing a weight 18 that is axially displaceable but not rotatable therein. Threaded in the weight 18 is a screw threaded member 9 coupled by a universal joint to the shaft 4. The bearing 16 is designed to permit the pulley 9 to tilt with respect to the shaft 4 of the package 3. If the speed of the shaft 4 varies, from that of the pulley 9, the weight 18 will be displaced on the screw-threaded end 19 and as a result the reaction of the weight 18 acting on the screw threaded end 19 varies the preasure of the pulley 9 on the driving roller 1. As the pressure increases the pulley will move readily adapt the speed of the driving roller In Fig. 5 the pulley 24 is driven by contact with a pulley 22 universally mounted on the shaft 2 of the driving roller 1. The pulley 24 is rotatable on an eccentric brushing 26 which may turn on the spindle 4. Bevel toothed rings 27, 28, 29 and 30 are attached, respectively to the pulley 24, to the spindle 4, and to an intermediate wheel mounted rotatably on said spindle. The toothed rings 27 and 29 are inter-coupled by a planetary wheel 32, the shaft of which is attached to the eccentric brushing 26. The toothed rings 28 and 30 are interconnected by a wheel 31 attached to the machine frame. If a difference in speed occurs between the pulley 24 and the spindle 4, the brushing 26 will turn at a speed which is equal to half the difference in speed between the pulley 24 and the spindle 4. If the brushing 26 so turns that the distance between the pulley spindle and the driving shaft 2 increases, then the rotation of the pulley 24 is retarded.

In a swing door assembly comprising a plurality of independently mounted swing doors, each formed of a glass panel and metal frame, and movable from an in-line position across the door opening to a staired out-of-use position at one side of the opening a spring door closer incorporating a fluid check is coupled to the top of each door and means is provided to disconnect the coupling when the panels are slid to one side to the stowed position. The doors may be coupled to the door closer in pairs. The lower pivot 19 is mounted on wheels 13 to run in a casing 14 and the upper pivot 27 is carried by a platform 21 slidable on rods 23 to the stowed position. The pivot 27 carries a plate 30 in which the coupling means is mounted, the door closer 9 being mounted along the lintel and having a depending spindle 10. To uncouple the door and its upper pivot from the closer 9 the door is swung through 90‹ to the open position when the door and its pivot 27 and the plate 30 can be slid away from a block 35 clamped around the spindle 10. A wedge plate 32 having an inclined slot 33 guided by pins 34 provides clearance once the door has started to move sideways. A latching device locks the plate 30 to ensure that the plate and the block 35 will re-engage when the doors are returned to the "in-line" position. Chains 48 along the upper and lower guideways are connected to a vertical shaft (49 Figs. 8 and 9) at the side of the door opening to ensure even running of the doors in the top and bottom guideways. The end doors adjacent the door jambs can have spring closers mounted in the floor since these doors are not slid sideways when stowed.

Abstract: 595,247. Electron discharge apparatus. BROADWAY, L. F., and ATHERTON, A. H. May 20, 1944, No. 9796. [Class 39 (i)] An electron discharge device comprises a resonator having a fixed wall 4 supported by sleeves 12 on rods 11 depending from the upper part of the envelope 1 and a flexible wall 5 which is deformable to adjust frequency by a sleeve 16 attached to a flexible disc 2 forming part of the envelope ; movement of the walls 4, 5 due to thermal expansion of the supports is in the same direction and variation of frequency from this cause, thus reduced or eliminated. The device shown, which operates by velocity modulation, comprises an electron gun 9 supported by a mica plate 10 from the rods 11, grids 6, 7 and a reflecting electrode 14 mounted within the sleeve 16. A further grid 8 is provided for acceleration of electrons from the gun. The lower ends of the rods 11 are supported from the pinch by relatively flexible connections 13. The sleeve 16 and the reflecting electrode 14 are secured to a mica disc 15 attached to a rod 17 secured to the disc 2. The lead 24 from the reflecting electrode 14 is led through the base of the device. The centre of the disc 2 is secured to a threaded rod 18 engaging a member 19 threaded in a disc 20 secured by screw 22 in a cup 21 attached to the outer part of the disc 2. The screws 22 engage inclined slots in the cup 21, whereby coarse adjustment for tuning is effected ; fine adjustment is effected by rotation of the member 19, the threads on this and the rod 18 being so chosen as to give differential movement. Energy is withdrawn from the resonator by a concentric line 27, the inner conductor of which terminates in a loop 28. The outer conductor is sealed to the ring pinch at the bottom of the device and should be flexible. If insufficiently flexible it should terminate a short distance from the oscillator which is then provided with a quarter-wave spaced sleeve surrounding the line. The electron gun 9 may be supported from below instead of by the rods 11. The envelope 1 is surrounded by a metal shield 25. According to the Provisional Specification, the compensation may be further improved by making the supports of different materials.

Title: Automatic optical target tracking
IPC: G01S17/66
Filed: 1974-03-05
Abstract: 1468237 Optical tracking BOFORS AB 5 March 1974 [13 March 1973] 9939/74 Heading H4D In an optical target tracking system, wherean image of the target is projected by an optical system on to a light sensitive detector surface the image comprising light emitted from or reflected, by means of, e.g. a laser, from the target, the image size of the target is increased when it is less than a predetermined size on the detector surface by increasing the unsharpness or blur of the image. The light from the target is received in receiver (Fig. 1) through optical system 5 and narrow band filter 7 which admits light exclusively in the laser transmitter spectrum, e.g. infra-red, on to four part photodetector 6 which may be photo avalanche semi-conductor diodes, arranged as sectors 6a, 6b, 6c, 6d. In one embodiment, Fig.2, the image falling on the detector plate 21 is varied in size by positioning the detector plane 23 away from the infocus image plane 29 to a degree determined by rotatable screw 25 driven by motor 27. In another embodiment, Fig. 4, the image in the detector plane is made unsharp by the interposition of a frosted glass plate 43. In a further embodiment (Fig. 3, not shown), a four quadrant prismatic disc (33) is interposed in the optical axis, to form four images of the target, each slightly displaced from the centre (Fig. 3c, not shown). The degree of blur may be controlled by target distance information obtained in the target tracking system, or elsewhere, and/or depending on detector signals indicating that the target image has reached a predetermined size on the detector surface. In the detector 6, Fig. 1, the quadrants 6a- 6d are individually electrically connected to produce from difference circuit 8, error signals corresponding to lateral angle error and elevational angle error plus a sum signal #, being the sum of signals from the four quadrants. The pulsed error signals 9, 10 are amplified at 12, 13 respectively, and converted into continuous servo signals by circuit 15. The sum signal 11 is gated through circuit 15 to circuit 17  which measures the time difference between a pulse from pulse unit 2 which enables laser transmitter 1 and the received pulse signal, to calculate the target distance which may be utilized to determine the target image size. This value is used to gate circuit 25 when the next received pulse is expected. AGC circuit compensates for changes in received signal strength.

Title: Improvements in or relating to processes of preparing fatty oils
IPC: C11B7/00
Filed: 1933-04-03
Abstract: <PICT:0402651/III/1> Fatty oils are freed from high melting point constituents such as stearin, palmitin and free fatty acids, by dissolving the oil in a liquefied normally gaseous organic solvent, chilling the solution and separating the precipitated substances. Solvents specified are butane, propane, butylene, isobutylene, isobutane, propylene, ethane, ethylene, dimethyl or methyl ethyl ether or ethylene oxide.  A fatty oil such as lard, cotton seed, sperm, soya or corn oil is fed through a pipe 1 and heat exchanger 4 to a tank 6 to which liquefied propane is admitted from a storage 56. The mixture passes to one of the heat-insulated chilling chambers 11, and the valve 12 or 13 is opened allowing the propane to vaporize, whereby the temperature of the solution is lowered to about 0 DEG  to - 10 DEG  C.  If desired liquid propane may also be p  injected into the bottom of the chamber.  The vapours pass to a condenser 15, and the chilled mixture containing precipitated stearin &c. is forced through a filter press 21 which has been pre-cooled by liquid propane.  The resulting wax cakes are washed with cold propane and are forced by an expeller 23 into a heater 26 provided with a steam coil 27.  The propane vapours thus formed pass through a pipe 28 to a compressor 52 and condenser 53, and the melted stearin passes to a stripping tank 32 where the stearin is treated with live steam.  The melted stearin is discharged through a pipe 35, and may be further treated to recover stearic acid.  The filtrate consisting of a solution of stearin-free oil in liquid propane, passes from the filter press 21 through a coil 16 to a flash tower 38 in which pressure is released and propane vapours pass to the condenser 53. The oil is then heated in a second flash tower 41, and is freed from final traces of solvent in a stripping tank 45 supplied with live steam.  The purified oil then passes through a cooler to storage.  If desired the precipitated stearin may be separated from the solvent and oil by centrifugal treatment.  The purifying treatment may be combined with an extraction process, in which seeds, animal tissue, plant fibre &c. are treated with the liquefied normally gaseous organic solvent under pressure, and the resulting solution of oil is filtered and treated with decolorizing carbon, clay, sulphuric acid or alkali and then submitted to the purification process, The low cold test fatty oils thus obtained are suitable for use in the manufacture of soft soap. harness oil or lubricating oil.  The process may also be applied to the separation of palmitic, stearic and other high melting point acids from the mixture obtained in fat-splitting processes.
