Title: Improvements in the production and use of battings
IPC: D04H3/02
Filed: 1967-07-26
Abstract: 1,182,674. Forming filamentary batts. CELANESE CORP. 26 July, 1967 [29 July, 1966], No. 34233/67. Headings D1F, D1N and D1R. A process for the production of a batting comprises continuously feeeding on to a moving surface a continuous web of crimped filaments which are generally parallel to the length of the web, which web is traversed across the surface to be deposited in partly overlapping folds, gaseous currents being used to determine the length of the web laid before each fold occurs. The web may be fed to the moving surface through an oscillating chute which confines the web sufficiently for a current of air to emerge with the web and carry the web beyond the point it would reach at the end of each oscillation by falling from the chute. Alternatively, the chute may be stationary, and gaseous blasts may be directed towards the web to force it beyond the position it would take in free fall. A pad for filling a cushion or like article is preferably made by folding or rolling a randomly folded web inside a batt made by the above process.

Title: Automatic-gain and bandwidth control system for transistor circuits
IPC: H03G9/24
Filed: 1960-10-06
Abstract: 937,536. Transistor amplifying circuits. HAZELTINE CORPORATION. Oct. 6, 1960 [Nov. 19, 1959], No. 34365/60. Class 40 (6). In an automatic gain control circuit for a radio receiver a gain controlling bias is applied from signal detector 11 to the base of I.F. stage transistor 29, via smoothing circuit 25, 27. The collector circuit of transistor 29 includes, in series with the primary of I.F. transformer 13 a D.C. load 35 and the amplified gain control voltage appearing across this is applied to a diode 37 to control its impedance. The diode 37 is supplied with a delay bias by means of potentiometer 43 and is coupled by condenser 39 to form a variable impedance shunt across the input circuit 7 of the I.F. stage. The transistor 29 is given a standing base bias by means of resistor 36. The component values may be chosen so that the decreasing impedance of the diode just compensates for the increase in input impedance of the transistor as the controlling bias increases; alternatively they may be chosen so that the diode impedance variations also compensate for the overall change in bandwidth due to change in both input and output impedance of the transistor. The Specification refers to the I.F. stage transistor 29 and the transistor in the preceding converter stage 5 as comprising portions of a multiple zone semiconductor device, the collector terminal of the converter and emitter of the I.F. stage sharing a common zone.

Title: Improvements in or relating to a fixed drum reel for fishing rods
IPC: A01K89/06
Filed: 1956-11-19
Abstract: 835,276. Fishing reels. MAUBORGNE, P. Nov. 19, 1956 [Dec. 1, 1955], No. 35251/56. Class 48. In a reel of the kind in which during casting the axis of the reel is disposed parallel to the fishing rod and the reel 14 is stationary as the line unwinds and in which the reel is movable from the casting position to a position nearly at right angles to the rod for reeling in, the reel rotates at reeling in about its axis and also about an axis nearly parallel to the fishing rod. The reel is detachably secured to a drum 15 rotatably mounted on a spindle 13 mounted on a cranked-arm 12 secured to the end of a worm 10 rotatably mounted on a fixed shaft 2, secured to a support 1. The drum 15 carries a gear 16 which meshes with a gear 17 rotatably mounted on a spindle 18 secured to the arm 12 and the gear 17 meshes with a non-rotatable gear 19 secured to the end of the fixed shaft 2. A shaft 4 having a handle 5 is rotatably mounted on the support 1 and carries a pinion 11 which engages the worm 11. On rotation of the handle the reel 14 rotates in the direction F<SP>1</SP> about the shaft 2 and the gear 17 runs around the fixed gear 19 to cause rotation of the reel 14 about its own axis. The first of these two reel rotations causes the line to twist in the direction F, thereby removing twists made by casting. Since the axis of the reel is not exactly at 90 degrees with the rod the line is uniformly distributed over the reel. The support 1 is rotatably mounted on a shank 3 supporting a cradle 6 for attachment to the rod. A catch on the support engages in two notches 7, 8 in the shank to determine the casting and reeling in positions. Alternatively a locking screw 9 is used to hold the shank and support in adjusted position. In another construction the shaft 2 is detachably secured to the support 1 and can be inserted in an axial housing in the shaft 4 of the handle 5. In a modified construction, Figs. 3, 4, 5 (not shown), the support is rotatably mounted on a spindle fixed to the cradle and is urged by a spring to the reeling-in position in which a stop on the support abuts a fixed stop on the cradle. The casting position is determined by the stop on the support abutting a manually movable stop on the cradle. The spindle also carries a cam which acts on a latch adapted to engage in a notch in a member secured to the worm, the arrangement being that when the reel is in winding-in position the cam holds the latch out of the notch but when the reel is in casting position the latch can be engaged with the notch to hold the reel stationary. In another embodiment the support is integral with the cradle and the reel is constructed as shown in Fig. 7. The hub 223 is keyed to a rotatable shaft and the cylindrical portion 213 of the reel is pivoted by means of screws 226, 227 to the hub. Thus the cylindrical portion can occupy the position shown for reeling-in or a position rotated through 90 degrees for casting. The two positions are determined by a spring-urged pin 215 on the cylindrical part engaging notches in the hub.

In Fig. 11 the pretreatment apparatus comprises bellows-like bodies 104 mounted in a tank containing the liquid, the upper ends of the bodies being attached to a float 102 which maintains the bodies below the liquid level. The bodies 104 may be made of glasswool, natural or synthetic fibre, wire gauze, permeable steel or semi-permeable membrane e.g. "Cellophane" (R.T.M.).
