Title: Cable spool winding
IPC: B66D1/30
Filed: 1953-08-31
Abstract: 737,352. Cable winding drums. LE BUS, F. L. Aug. 31, 1953, No. 24048/53. Class 78 (5). A cable winding drum 18 is provided with end brake flanges 22, 24, grooves 30 having a space 32 between their ends, an end filter 46 at one end of the space, the inner face being curved to guide the cable to the beginning of the adjacent groove, and at the other end of the space a rise and filler 38 with a diminishing groove to receive the last wind of the first layer of cable and raise the cable to start the second layer. The brake flange 24 has an aperture 26 and two chocks 28 for the end of the cable 60. The filler 46 has an aperture 49 for the cable to pass to the aperture 26 to be secured by an end clamp 62 and the filler 38 has its wider end grooved to abut and coincide with the end groove 30 on the drum. Kickers 54, 56 are provided on the flanges in line with the ends of the part 32. The edges of the kickers are chamfered and the ends of the grooves 30 at the part 32 are sloped to enable the cable to be wound smoothly on the drum in a helical path as the drum is rotated. At the end of the second wind the end kicker 54 effects the reverse movement, and at the end of the third wind the kicker 56 is effective to reverse the direction. The winding proceeds in a helical path, the cable being laid in the grooves formed by the previous wind. In an alternative construction the grooves are continuous on the surface, as shown in Fig. 17. The grooves are formed by two identical arcuate grooved members 85 secured to the drum and by a curved member 86. The members 85, 86 have slotted ends and chamfered lower edges for securing to the drum. End fillers 95 and 101 are secured to the drum. The filler 95 is a tapered member fitting against the brake flange 83. The rise filler 101 has a groove 107 at one end; it has an inner curved surface and a raised part 109. A pair of kickers are provided on each brake flange, the kickers having a curved surface.

Abstract: 738,762. Extruding. COMPAGNIE GENERALE DU DURALUMIN ET DU CUIVRE. Sept. 30, 1952 [Oct. 2, 1951], No. 24454/52. Addition to 643,857. Class 83 (4). The extrusion apparatus of the parent Specification is modified in that the mandrel has portions of a diameter greater than that of the forward cylindrical portion so that the extruded tube has at least two parts of different but uniform internal diameter. The mandrel comprises a cylindrical front portion 5 followed by a tapered portion leading to a part-spherical portion of which the part from C to E is of larger diameter than the cylindrical portion. During the extrusion operation the internal diameter of the tube will at first be determined by the diameter of the cylindrical portion as with the apparatus of the parent Specification, but when the portion C to E has passed through the die 10, then this enlarged portion will determine the internal diameter of the remainder of the extruded tube.

Title: Improvements in or relating to frequency dividing circuits
Inventor: ROGERS MICHAEL JOHN
IPC: H03K3/288
Filed: 1968-05-22
Abstract: 1,273,536. Frequency dividers. SMITHS INDUSTRIES Ltd. 21 May, 1969 [22 May, 1968], No. 24465/68. Heading H3T. A bi-stable frequency divider comprises two transistors 1, 2 cross-coupled between collector and base, a capacitance 6 coupling their emitters, and switching means such as 7, 8 for connecting the emitters to a supply source under the control of input signals. As shown, when transistor 2 has been conducting and 1 off capacitor 6 is charged with the right-hand plate positive. 7 and 8 are normally off so that the circuit draws no current and capacitor 6 holds its charge. When the next input pulse at 14 makes 7 and 8 conduct the charge in the capacitor causes transistor 1 to become conductive and 2 to remain off so that the conductive states reverse. The charge on 6 is also reversed so that the next pulse causes the initial state to be restored.

A machine for cutting a profile comprises a spindle 11 including means, such as a nut 3 and bushes, for securing a master profile 1 and workpiece 2 thereto, a quill 4 relative to which the spindle is rotatable, a follower roller 5 fast with the quill carrier 8 for engagement with the master profile and a cutter 6 for engagement with the workpieee, the quill and quill carrier being relatively movable and the distance between the axes of the roller 5 and cutter 6 being fixed. The quill 4 is slidable in the quill carrier 8 under the action of the roller 5 engaging the master profile 5. The distance between the axis of the roller and cutter can be adjusted by screw 9. In a modification (Figs. 5 and 6, not shown), spindle 11 can be rotated by an electric motor (61) (Fig. 6, not shown), through reduction gearing (59) and a worm (28). An annular brake pad (57) is pressed adjustably against a top surface of the worm to prevent chatter. Also, the pressure with which the spindle and master profile are drawn towards the roller 5 can be adjusted by an adjustment nut (78) threaded on a piston-rod (70) of a piston-and-cylinder arrangement incorporating a spring (72) urging the quill 4 into the quill carrier 8. Further, a microswitch (30) normally closed, willbe opened if the roller 5 moves to the right due to its lack of engagement with the master profile, whereby the machine stops. In another modification (Fig. 7, not shown), a carrier 3 for a drum cam is provided, and the spindle is horizontally arranged in a carrier which is steadied by a steady bar.

Abstract: 795,684. Contacting gases with liquids. AMERICAN AIR FILTER CO., Inc. Aug. 26, 1955, No. 24557/55. Class 55 (2). Apparatus in which gases are contacted with liquids, e.g. an air cleaner in which dust-laden air is contacted with oil, comprises a housing having spaced walls 11 and 12, two filter pads of crimped wire 13 and 14, an apertured plate 20 on to which a controlled amount of liquid is fed through a central pipe 22 and means to pass the gas upwardly through the apertures of the plate at a velocity suflicient to entrain liquid accumulating about the edges of the aperture, entrained liquid being separated by the pads 13 and 14 and draining by a pipe 18 to a tank 19. The apertures 21 may be formed by punching holes in a plate leaving upwardly bent tabs 27 for each hole attached to the plate. The size of the apertures may be from # to 1<SP>1</SP>/ 2  inches and may, e.g. be # inch holes on ¥ inch centres, such a plate would require a minimum gas velocity of 725 feet per minute. In a modification the apertures in the plate 20 are provided with flapper valves hinged to the plate. Alternatively, the plate may be of thin flexible material, e.g. rubber, plastic or thin metal, and cut to provide triangular or square flaps. An apparatus may comprise a number of apertured plates, each having flapper valves adapted to open at a different pressure and thereby progressively increase the operative capacity of the apparatus as the load on the apparatus increases.

Abstract: 1472495 Transistor amplifier; amplitude limitation NIPPON GAKKI SEIZO KK 9 June 1975 [11 June 1974] 24691/75 Heading H3T To prevent breakdown by excessive current excursions in a non-saturating (triode-like) FET Q 1 , a circuit includes in series with the source of Q 1  a conventional saturable FET Q 2  or a bipolar transistor (Q 3 , Fig. 6, not shown), the input signal SG being applied between the gate of Q 1  and the remote side of Q 2  (or Q 3 ), and a bias being applied to the control electrode of Q 2  (or Q 3 ). If Q 2  (or Q 3 ) is of the same conductivity type as Q 1  its drain (or collector) is connected to the source of Q 1 ; if of complementary type (Fig. 5, not shown), its source (or emitter) goes to the source of Q 1 ; in each case a variable bias supply B 1  is connected between its gate (or base) and source (or emitter), a voltage bias for a FET but current bias of opposite sign for a bipolar transistor of similar conductivity type. The device Q 2  has quiescent working point halfway up its non-saturating range below pinch-off; any excursion of Q 1  tending to take the current beyond the saturation level of Q 2  as set by its bias causes a large rise in the drop across Q 2 , which drop appears in series with the signal SG at the gate of Q 1  to oppose the current rise. The working point may be set by a D.C. bias (not shown) in series with SG. The output appears at T 5  across load Z on the drain of Q 1 . Amplitude limitation may be suppressed above a given frequency by a by-pass capacitor across Q 2  (Fig. 7, not shown), or near one or more resonance frequency by a series tuned circuit or a plurality in parallel across Q 2  (Fig. 9, not shown). The load Z may be a tuned tank circuit comprising a transformer with tuned secondary (Fig. 10, not shown). All devices may be reversed in conductivity type with associated reversal of power and bias supplies. The circuit may be integrated.
