Title: Process of making polymeric fibres
IPC: D21H13/10
Filed: 1974-03-11
Abstract: 1458703 Flash-spinning CROWN ZELLERBACH INTERNATIONAL Inc 11 March 1974 [12 March 1973] 10819/74 Heading B5B [Also in Division D2] Polymer fibres are prepared by flash-spinning a mixture of the polymer and a solvent at a temperature above the boiling point of the solvent and sufficiently high to render the polymer plastic or in solution. The flash-spinning is accomplished by passing the mixture from a zone of higher pressure into one of a pressure of at most 600 mm. Hg. so that substantially all the solvent evaporates precipitating the polymer as a fibrous mass. The low pressure zone is in direct communication with a disc refiner, so that the fibrous mass is refined at a pressure which is also below 600 mm. Hg. A non-solvent such as water is optionally present in the original mixture and a hydrophilic water-dispersing agent such as polyvinyl alcohol is preferably also included. The use of polyethylene and polypropylene is exemplified.

A mirror carried or moved by the coil directs light beams through a slot to produce, for each half-oscillation, one or more points on sensitized paper or other material to which rectilinear or other movement is given, so that a photographic reproduction of the elements of the picture &c. is obtained. Light from a source A passes through slots F and lenses D and is reflected by mirrors C on to a mirror carried at B by the oscillograph coil mounted between the poles of an electromagnet J. From this mirror the light is directed through a focusing- lens E and slot K on to sensitized material on a support G in a light-tight casing H. The support G receives rectilinear, rotary, or other movement. Arrangements are described whereby each halfswing of the mirror produces one, two, or four points on the sensitized material.

Title: Improvements in and relating to variable speed power transmitting mechanism
IPC: F16H61/02
Filed: 1921-04-19
Abstract: 181,193. Enard, H., and Heyl, W. J. April 19, 1921. Variable-speed toothed gearing, in which the speed changes are effected by the operation of clutches, is rendered automatic by a yielding coupling. The effect of the change of load on a shaft 5, Fig. 2, is to cause a ball 13, Fig. 7, to move over the ends of a set of rods 10, 11, 12, which operate different friction clutches in succession. In the high-speed position, as shown in Figs. 1 and 2, the springs 26 of the coupling are not compressed, and the balls 13 act on the ends of the rods 10 of the highest gear. Spur-wheels A, B, C secured to a driving-shaft 2 mesh with wheels a, b, c loose upon the driven shaft 5. The balls are carried in pockets upon one coupling- member 14 secured to the shaft 5. The other coupling-member 24 is secured to the hubs 21 of the gears a, b, c and to abutment clutch members 19. These gears have webs 18 adapted to be gripped between the members 19 and sliding members 29, 30, 31 adapted to receive thrust from the rods 10, 11, 12, respectively. In the lowestspeed position, as shown in Figs. 5 and 6, the springs 26 are compressed to the maximum extent and the balls 13 are moved round into engagement with the ends of the farthest and shortest rods 12. The thrust pressure for the friction clutches is obtained from a spring 34, which pulls the members 14, 24 together and in effect transmits thrust through a thrust ring 32 to the balls 13 and clutch-operating rods.

Filed: 1921-04-19
Abstract: 178,005. White, A. E., (Goodrich Co., B. F.). April 19, 1921. Tyres, elastic, special apparatus for making.-A machine for stripping tyres from cores is characterized by a semicircular series of fingers 38 which are moved radially but are held against circumferential movement relatively to the core. The whole operation is completed in one revolution of the shaft 11 and the action is automatic. The shaft 11. which is mounted in bearings 12 and in the fixed chuck member 13, is rotated by two reciprocating racks 64, connected to the piston 59 and each driving one of two gear wheels 68, which are in turn connected to the shaft by pawls 72, and stops 76. Pressure fluid is admitted to the cylinder through a fourway valve 93 controlled by a lever 101, which is moved to start the machine by admitting the fluid to the lower part of the cylinder. Stops 104, 105 are provided on the rack-bars and coact with an extension 103 of the control lever, first to reverse the lever at the end of the upward stroke and second to throw the lever into neutral position and stop the machine at the end of an operation. The chuck 13 for holding the core comprises two fixed points 17 and an adjustable point 18, the adjustment of which is made automatically at the beginning of the operation by a gear and rack device driven, through spring connections, from a, rock-shaft 29 actuated by a cam 78 on the rack. bar. The point 18 is retracted at the end of the operation to release the core by the spring 82. The push fingers 38 are loosely connected to levers 33 by pins 37, slots 36, springs 41 and stops 42, 43, and move between fixed guide-plates 40 the ends of the pins 37 traversing slots 39 substantially parallel to the contour of the core. The levers are held by springs 35 against a cam consisting of a semicircular part 31 and a volute part 30 by which they are successively thrown out to the position shown in dotted lines. In this position the levers are held by spring latches 47 engaging behind the stop shoulders 46. The latches are carried by a spring-controlled sleeve 49 which is moved at the end of the operation to release the levers by a lever 56a which is actuated by a push-bar 83 provided with a gate-latch 88 coacting with a cam 92<1> on the rack-bar.

Title: Improvements in and relating to line scanning circuits for television and like apparatus
IPC: H03K4/28

Abstract: 666,900. Saw-tooth generating circuits. COURT, P. R. J., and PYE, Ltd. April 28, 1950 [April 29, 1949], No. 11409/49. Class 40 (vi). An electromagnetic scanning circuit comprises a valve having at least two grids between cathode and anode with a feed-backtransformer connected with one winding between the second grid and H.T.+ and a second winding connected in series with a resistor between the control grid and cathode and wherein the anode of the valve is coupled to the deflecting coils with which an efficiency diode is associated. Fig. 3 shows a line scanning circuit for television apparatus which oscillates by virtue of the transformer coupling T2 between the screen and control grids and in which a portion of the scan is provided by an efficiency diode D, the D.C. voltage produced across the load of which may be used to supplement the H.T. supply or for any other purpose. The resistor R in the control grid circuit limits the positive excursion of the grid voltage swing and the proportion of the total scan during which valve V is conducting may be adjusted by varying the bias of the valve, the value of resistor R or the ratio of transformer T2. In a modification shown in Fig. 5 negative-going synchronizing pulses are applied to the control grid circuit at point E and the amplitude of scan is adjusted by variation of inductor L2 connected in series with the defecting coils, a damping circuit comprising a series-connected capacitor and resistor being connected across it. The frequency may be varied by alteration of the inductance of the windings of transformer T2 by either varying the gap in the iron circuit, varying an inductance in parallel with one of the transformer windings or by varying an inductance L1 which is connected in parallel with a third winding on the transformer T2. E.H.T. voltage may be derived from the line fly-back voltage produced across the scanning output transformer.
