Title: Improvements relating to the spinning and winding of elastic filaments
IPC: B29D99/00
Filed: 1936-06-13
Abstract: <PICT:0481589/IV/1> Artificial elastic filaments particularly those from mixtures of rubber latex and viscose, are obtained by extruding the spinning solution through spinnerets into a coagulating bath, passing the filaments directly from the bath on to the surface of a revolving heated drying cylinder, then through powdered vegetable or mineral matter such as chalk maintained in heated condition, and cross-winding the dried filaments on to spools.  Preferably, the spinning solution is passed under gravity or air pressure from one or more containers and through interchangeable nozzles. Longer capillary nozzles are used when finer filaments are required.  After leaving the drying cylinder the filaments may pass through powdered chalk on a heated tray connected with a traverse motion by which the dried filaments are crosswound on to winding spools.  If desired, the filaments may be subjected to a re-winding operation during which they are again passed through powdered vegetable or mineral matter such as chalk.  They may then be vulcanized.  As shown in the Figure, spinning solution passes under gravity or air pressure from container A to and through the removable nozzles D into a coagulation bath C. The container A is provided with a cover a, filling aperture a1 and a row of tubes B leading to the nozzles D.  The filaments E leave the coagulating bath and pass directly to the surface of a revolving heated drying cylinder F.  They pass from the drying cylinder to a guide roller F1 and along a reciprocating tray G containing chalk or similar powdered vegetable or mineral matter and heated by gas, electricity, or steam.  They are then wound on the spools H by means of the rollers J.  The drying cylinder, the spool driving rollers J, and the reciprocating mechanism for the tray G are driven from a main shaft K.  The movement of the tray is facilitated by mounting it on wheels g which travel along guideways.  The rollers J may be covered with a yielding material for protection of the filaments.  The thickness of the filaments may be varied by adjusting the speed of the drying cylinder or of the spool driving rollers.  Specification 419,021 is referred to.

Title: Hydro-pneumatic lifting jack
IPC: B66F3/42
Filed: 1946-06-01
Abstract: 612,763. Lifting-jacks. BROOKE, H. L. June 1, 1946, No. 16709. [Class 78 (iii)] In fluid-pressure actuated jacks of the kind in which the ram is raised by liquid forced into the cylinder from a reservoir surrounding it by pressure fluid supplied from an external source, the reservoir is of low height, holds all the liquid required for lifting purposes and communicates with the cylinder only through a single valve chamber containing a spring-pressed ball valve which can be unseated by mechanical means to permit lowering. The reservoir 19, Fig. 1, comrnunicates with the cylinder 13 through ports 46 which open into a valve chamber 45 containing a spring- pressed ball valve 47, Fig. 4. This valve can be unseated by the head 50 of a pull-push control 49 which is mounted on the hollow handle 23 of the jack. In the position shown, the head restricts the flow of liquid from the reservoir to the cylinder. The pushpull device has means for locking it in either of two positions comprising a projection on the cable and two recesses in the sheath. The handle is connected to the supply of pressure fluid by quick release means 27 and contains a triggeroperated valve 28, Fig. 3, which in the position shown connects the port 36 of the handle leading to the jack to exhaust through the port 35 but when raised connects the part 36 to the supply of pressure fluid through the passage 39. In a modification, the head 50, Fig. 6, is moved by partial rotation of a rod 59 which is slidably mounted in a bracket 60 on the handle to which is secured a pin having a sharp edge 70, forced by the spring 72 into engagement with an axially-extending cam 66 secured to the rod 59. Rotation of the rod 59, limited between fixed stops by the cam 66, forces the axially-extending surface of said cam to react against the edge 70, thus sliding the rod 59 through the bracket 60 and actuating the ball valve by means of the movement imparted to the rod 64 through a bracket 63. Specification 346,684 is referred to.

Title: Improvements in pulverizer mills
IPC: B02C15/08
Filed: 1920-06-21
Abstract: 145,497. Fuller-Lehigh Co., (Assignees of Fuller, J. W.). June 1, 1918, [Convention date]. Mills and apparatus; ball-and-ring mills.-In a pulverizing-mill comprising grinding-elements within a grinding-zone, a settling-zone is provided above the grinding-zone and a superposed chamber above the settling zone having means for directing air currents outwardly, the settling-zone being of sufficient height to permit of the separation of insufficiently-ground particles by gravity before the pulverized material reaches the superposed chamber. The invention is described in connexion with a ball-and-ring mill. The grinding- ring 15, Fig. 1, is supported upon the base of the casing 13 but is spaced from the vertical wall thereof, or furnished with apertures along its outer edge to provide passageways 16 opening into the fan chamber formed between the casing 13 and the top of the standard 11. The cylindrical wall 17 of the separating- chamber or settling-zone 17<1> has depressions or ridges 18 to engage corresponding ridges or depressions on the top of the casing 13 and ring 15, and is held in position by bolts 20 passing through flanges 19. A screening-chamber comprising a circular frame 22 carrying a screen 24 and outer wall 25 is bolted to the top of the section 17. The frame or yoke 34 on the central vertical shaft 31 is provided at its lower end with radial arms 35 carrying members for 'driving the grinding-balls 36. A number of inclined lifting-blades 37 carried by the intermediate portion of the frame 34 extend through the settling-zone 17<1>, the lower ends of the blades terminating above the contacting surfaces of the balls 36 and ring 15 and the upper ends terminating below and just inside the lower ends of the radial fan-blades 38 mounted within the screening - chamber upon vertical standards formed at the upper end of the yoke 34. A funnel. 29 attached to the underside of the cover-plate 28 directs the material fed by the feeding-device 27 towards the centre of the apparatus and out of the path of the pulverized material. The pulverized material is lifted by the upwardly-moving currents of air due to the action of the fans, and the finer particles pass through the screen 24 and down through the communicating passageways 21, 16 to the chamber beneath the ring 15 whence they are discharged through a spout 26 by fan blades 40 carried by a disk 39. In a modification, Fig. 2, the separating-zone and the superposed chamber are formed within an integral casing 50 attached at its lower end to the top of the casing 13. In some cases, the screen is dispensed with; or it may be replaced by a series of baffles 52.

Title: Improvements in electrical control for mechanisms for setting or displacing a tool or other device by a predetermined amount
Filed: 1922-09-15
Abstract: 210,355. August, J. R. C., and Hunter, E. K. Sept. 15, 1922. Gauging-devices; indexing. -In an electrical control arrangement for a setting mechanism for displacing a tool or other device to a predetermined amount such as that described in Specification 200,127, the tool &c. which is normally locked to a stationary element is first connected to a movable element, then disconnected from the stationary element and finally, after partaking of the movement of the movable element, is again connected to the stationary element before being disconnected from the movable element. The carriage 18 to be displaced may be coupled electromagnetically either to a fixed member 20 or to a spindle 17 which is reciprocated accurately between set limits by means of a setting device comprising a number of cam elements 15 loosely arranged between a fixed abutment 97 and a collar on the spindle 17 and having cam projections provided with accurately ground spacing parallel ,surfaces 23, 24. The sleeves 15 coact with sliding bushes 16 having pins 25, each sleeve with its bush forming an element capable of expansion in length by the distance between the surfaces 23, 24. The sleeves 15 are rotated bv means of feathered six-toothed ratchet wheels 13 operated by pawls mounted on a spindle carried between end flanges 2, 3 which are constantly oscillated from a shaft 8. The pawls are brought into engagement with their ratchet wheels by means of electromagnets 5 mounted on a bridge-piece 4. The energizing of the magnets is controlled by a number of drums 99, 100 each having six segments of different lengths adapted to co-operate with brushes 102 mounted on levers 103 which are normally held against the commutator surfaces by springs. By means of cams 106 the levers 103 are lifted once for each revolution of the drums into the range of a locking catch 108 and are withdrawn on energizing the magnets 110 to free the brush 102 so as to energize the desired magnet 5. A master switch drum 111 rotating at six times the speed of the drums 99, 100 &c. is provided with overlapping contact strips one of which operates the magnet 21 while the other operates magnet 19. Thus for each revolution of the drums 99, 100 the spindle 17 may be displaced by any amount between unity and six times the sum of the distances between the spaced parallel surfaces on the sleeves 15. These distances are arranged in the geometrical series 1, 7, 49, 343 - - - in which the ratio is one plus the number of commutator segments. The circuits of the magnets 110 are controlled by keys which are numbered in units of displacement as shown in Fig. 13.

Title: High speed switching circuits
IPC: H03K17/0412
Filed: 1972-04-12
Abstract: 1335795 Switching circuits CPS Inc 12 April 1972 [3 May 1971] 16933/72 Heading H3T [Also in Division H2] A switching circuit for rapidly reversing the voltage across a capacitive load 11 comprises opposite polarity voltage sources 12, 13 connectable to the load by switches A and D and an inductance for resonantly reversing the capacitor voltage while the switches are open. The circuit is described as applied to switching the voltage of the supply to the cathode and anode of a C.R.T. tube of the type in which the colour depends upon the electron velocity. Assuming switch A to be made, the load is charged to 2 kV. Switch A is now opened and switch C closed. Resonant reversal of the capacitor voltage now takes place via diode 17, inductor 14 and switch B. After a time equal to the reversal time switch B is opened and switch D closed so that the reversed voltage (- 2 kV) is retained. Restoration of the original voltage is similarly effected. Each switch operation takes place under zero voltage and/or current conditions. Switch C may, as shown in the upper part of Fig. 4, comprise a series chain of transistors paralleled by diodes 56, resistors 57 being provided for equalising the transistor voltages. Resistors 61, together with diodes 62, assist switch-off and diodes 62 maintain the transistor chain non-conductive when the voltage across the chain is reversed. A similar circuit, shown in the lower part of the Figure, is used for switch D. The voltage charge command is applied to a pair of bi-stable circuits 43 which remember the required state. The complementary outputs of these circuits are applied directly or via a monostable circuit 64 to AND gates 47, 48 to switch switch B for a period sufficient for the reversal to be effected and a delay 63 switches on switch D after this period. Fig. 3 shows two such voltage reversal circuits 27 and 28 to provide 1KV and 2KV levels respectively for the cathode and final anode of a penetration type colour cathode-ray tube, whereby, when combined with a 9 KV supply from 34, voltages between cathode and anode of 6, 8, 10 and 12 KV may be provided and corresponding colour changes are effected. The 9 KV supply derives its input from a low voltage supply 32 via an isolating transformer 33, the supply being stabilized by a feedback circuit comprising an isolating high link 36. The high voltage components are contained in a copper mesh screen 37, and an earthed copper mesh screen is provided at the input.

Title: Improvements in or relating to banding machines
IPC: B65B27/08
Filed: 1945-07-03
Abstract: 602,808. Banding - machines. CAMCC (MACHINERY), Ltd., and LANGFORD, J J. July 3, 1945, No. 16958. [Class 94 (i)] In a machine for securing bundles of paper sheets or like articles, the article: are stacked on a band of binding material previously laid on the upper surface of a vertically movable work table urged up wardly by resilient means, the stack ther being pressed down by a mechanically operated presser until its upper surface lies at a chosen level, whereupon the ends of the band are mechanically folded in turn across the stack in overlapping relationship and secured together. Binding material 24 from a reel 23 is fed over the work-table 10 by manually rotating a handle 34 in an arcuate slot 35 between stops 38, 39, whereby a feed roller 26 is rotated, ratchet mechanism 32 avoiding rotation on retraction of the handle, and the stop 39 being adjustable to vary the length of the band according to the size of the stack. The table 10 is of cruciform shape and its limbs 10b are bestraddled by side lays 14, 15 adjustable according to the width of the stack. A pedal 48 is then depressed, when by link-and-lever mechanism the knife 40 of a guillotine 40, 41 moves down to sever the desired length of band, and an adhesive-applying roller 53 whose bearings are linked to the knife 40 moves out of contact with a supply roller 52 and into contact with the severed band, whence as the band is drawn down during the banding operation the roller 53 rotates and applies adhesive up to the end of the band. The roller 52 is rotated by connection with the feed roller 26 so as to supply adhesive from a bath 50 to the roller 53. The pedal 48 also operates a trip clutch 70 effective only for one revolution of the gear wheel 68 mounted loosely on the shaft 69, whereby the wheel 68, driven by an electric motor through a pulley 58, is put into operative connection with the shaft 69. The shaft 69 through a cam 83 and link- and-lever mechanism 85, 89 causes a bracket 91 to be depressed, whereby the stack, having been manually placed on the band on the table 10, is depressed by two saddle members 92 until its upper surface is level with the top of the side lays 14, 15, the table 10 being depressed against the action of springs normally urging it upwards to the position shown. Through similar bevel wheels 74 at each end of the shaft 69, cams 75, and link-and-lever mechanism, folding blades 21, 22 are moved in turn over the top of the stack, passing between the saddles 92 and folding the ends of the band over the stack in overlapping relationship, the ends being secured by the adhesive on the lower side of the upper band end. The blade 22 is slightly higher than the blade 21. A hinged guide 21' is deflected by the blade 21 and in its normal position prevents the end of the band when fed over the table from fouling the blade 21. The blades are in turn retracted and the saddles raised by continued rotation of the shaft 69, and the completed package removed by hand.

Abstract: 957,019. Phase modulation; single sideband systems; frequency changer systems. L. R. KAHN. May 13, 1960 [May 15, 1959], No. 17058/60. Drawings to Specification. Headings H3F, H3R and H4L. In a phase modulated carrier, e.g. S.S.B. system in which the carrier is transmitted after frequency multiplying by one (say N) of several preselected factors the phase modulating signal frequencies are kept constant by frequency dividing, by a fixed large factor D, the initial modulated carrier and then multiplying by an D D integer - where - is switchably selectable in N N accordance with the final frequency multiplying factor N of the transmitter. Thus, if N D equals 1, 2, 4 or 8, D may be 8 and - then N equals 8, 4, 2 or 1. Frequency changing may be operated selectively with the first frequency multiplying stage so that the transposed frequency lies within the pass band of subsequent amplifiers, each frequency changing oscillation being derived by selectable frequency multiplying stages from a crystal oscillator. Frequency changing may also be provided to progressively change the carrier frequency in the pass-band before final frequency multiplication. A single sideband (with its full carrier) limited to constant amplitude may be used and the multiplied transmitted frequency amplitude modulated by the modulation envelope of the initial single side-band plus carrier derived from a diode detector; or amplitude modulated by only the fundamental frequency of the envelope of the sideband plus carrier, obtained by beating the latter with the carrier frequency in a product demodulator; the latter system being compatible with reception either in a single or a double sideband receiver.
