Abstract: 805,414. Fishing rods. BUSI, G., CONTESINI, G., and TAGLIARINI, L., [trading as Z.O.R.T.A.C.]. April 17, 1957 [April 17, 1956], No. 12559/57. Class 48. A fishing rod having an automatic line retraction and release device comprises a reciprocating member 22 slidably movable from a rest position to a set position against the action of spring means such as an elastic thread 26, means controlled by the tension of the line 33 for locking the reciprocating member in the set position and means on the reciprocating member for gripping the line when the reciprocating member is in the set position and rendered inoperative when the reciprocating member is in the rest position. The reciprocating member 22 is slidable in a tubular part 14 of the rod and has a portion 45 which projects through a longitudinal slot 24 therein. The elastic thread 26 is secured to the lower end of the reciprocating member and extends through the tube 14 and through a further tube 16 to a plug 28 secured to the end of the further tube. The reciprocating member is locked in the set position by a hook 37 on its end engaging a hook 36 on a member 35 slidable in a box 25 connected to the tube 14. A trigger 30 having an eye 32 through which the line 33 passes is pivoted to the box and has a nose 34 engaged in a recess in the sliding member 35 so that movement of the trigger towards the rod, due to a fish biting, causes disengagement of the hooks 36, 37. Outward movement of the trigger is limited by a second nose 38 thereon abutting the box 25. The trigger, when not in use, may be secured to the rod by a clip 39. The means on the reciprocating member 22 for gripping the line comprises a cross-shaped member including a sleeve 43 through which the line passes and a cylindrical member 44, Fig. 5, connected to the sleeve 43 and slidably mounted in the projecting part 45 of the reciprocating member. A screw 46 passes through the end of the projecting part 45 and through two longitudinal slots 47, 48 in the slidable member 44 and a spring 55 abuts the screw 46 and is attached to a rubber or cork piston 49 within the slidable member 44. When the sleeve 43 is pushed towards the rod the spring 55 is compressed and the line is clamped between the piston 49 and the sleeve. The sleeve is held in this line-gripping position by a projection 53 on the free end of a blade-spring 52 secured to the sleeve engaging in a hole 51 in a member 50 secured to the reciprocating member. The projection 53 is disengaged from the hole 51 by striking a release-rod 54 connected to a bush 62 mounted on the free end of a helical spring 61 located at the rest position of the reciprocating member and adapted to cushion the force of the reciprocating member. A handgrip 15 is secured to the tube 16. Means for connecting a reel includes a sleeve 18 surrounding the tube 16 and provided at its ends with nuts 19, 20.

Title: Improvements in quilting machines
IPC: D05B11/00
Filed: 1960-04-12
Abstract: 941,923. Load handling. A. SCHWARZBERGER. April 12, 1960, No. 13015/60. Heading B8H. [Also in Divisions D1 and E2] A work-holding frame, mounted on a carriage arranged to be moved under the needle of a sewing-machine for producing a predetermined pattern of stitching, is automatically transferred, on completion of the pattern to an adjacent table, and a freshly-loaded frame is automatically transferred from the latter to the carriage. Work 50 is held by a frame 51 supported by a carriage 40 arranged to move frame 51 under a sewing-machine 21 mounted on a fixed overhead frame 20. A table 60 carries a pivoted shaft 72 to which is fixed a pair of spaced arms 73 each of which is formed at its free end with a hook 73a closable by a pivoted finger 73b. During the sewing operation the arms 73 are inclined away from the sewing- machine. At the end of the sewing operation, when carriage 40 is nearest to table 60, a pattern. follower closes a switch, whereby a valve 65 is opened to admit compressed air via a conduit 66 to the upper end of a pneumatic jack 79, the piston-rod 79a of which is pivoted to the arms 73. The latter are thereby swung towards the carriage 40, and on reaching their position nearest to carriage 40 a detent 73f on an arm 73 engages a plunger 73e to reverse the valve 65 for supplying compressed air via a conduit 66a to the lower end of the jack 79. The arms 73 then swing away from the carriage 40, and pins 75 projecting laterally from the frame 51 are engaged by the fingers 73b. Frame 51 is thereby transferred to table 60, its trailing end being supported intermediately by pins 77d projecting laterally from brackets 77 rising from table 60. While a sewing operation is in progress, a second frame 51, supported on table 60, is loaded with fresh work. Said frame abuts the vertical arm 105b of an L-shaped bracket projecting through a slot 60c in table 60. The horizontal arm 105 of the bracket is coupled by a lug 105a to a screwed shaft 103a adapted to be rotated by a chain 102 from a motor 100. When the arms 73 reach a position C in their return stroke, an arm 73 closes a switch 97 to start motor 100, whereby the freshly-loaded frame 51 is pushed from table 60 on to the carriage 40 under the frame 51 which is being transferred from the latter to table 60. At the end of its forward stroke, lug 105a operates a reversing switch 107, and at the end of its return stroke it operates a limit switch 108 to stop motor 100. Specification 941,021 is referred to.

Title: Improvements in or relating to rotary wing parachutes
IPC: B64D19/02
Filed: 1948-05-13
Abstract: 647,569. Rotary wing parachutes. TUSTANOWSKI, J. May 13, 1948, No. 13133. [Class 4] Each blade of a rotary wing parachute is provided with an automatic regulator which operates, during launching, and under the control of forces derived from the rotational motion of the rotor, to change the blade setting angle from a first value, providing a high auto-rotational moment for accelerating the rotor, to a second value appropriate for stabilized flight at a low velocity of descent. The regulator may also on landing increase the blade setting angle from its second value to a third value providing an increased lift force and braking of the rotor. The blade setting control may be quasi-reversible or irreversible and may comprise mechanical or hydraulic operation. In the arrangement shown in Fig. 10, which is of the mechanical and quasi-reversible type, the part 21 is secured to the rotor hub (not shown) and the part 22 forms part of the blade root and transfers axial and torsional loads therefrom through a shell 23 to a multi-start quick-pitch thread cam 24 co-operating with a threaded part 125 fast with the part 21 and free to rotate on interengaging internal sleeves 229 and 71. Members 28, 30 which are secured together and are bonded to a rubber bush 27 are free to rotate on the sleeve 229, a washer 31 being provided to cater for end thrust. The effect of centrifugal force acting on the rotor blade as a result of initial high auto-rotation causes the members 22, 23 to move outwards a distance a to effect an increase of blade pitch to a predetermined angle limited by the abutment of members 23 and 28. The manually controlled mechanism which provides for a further increase of blade pitch prior to landing comprises a tapered ring 73 composed of a number of segments held in engagement with the tapered faces 74 of the member 71 and a washer 75 by a sleeve 72 which, when moved in the direction d frees the segments 73 and permits the members 71 and 229 to move outwardly a distance b to permit the further increase of blade pitch. Fig. 4 illustrates an irreversible hydraulically - operated regulator which does not include provision for a further increase of blade pitch prior to landing. The member 22 is attached to a threaded cylinder 35 interengaged at 44 with an inner member 41 fast with the member 21. The annular cavity formed between the members 35 and 41 contains liquid which, under load created by outward movement of the blade, opens a spring- loaded valve 36 and flows into a cylinder 38 to displace a spring-loaded piston 40. Should the balance of pressures be upset the valve 36 will reseat and to reset the regulator to its initial position the valve must be raised manually. Specification 647,564 is referred to.

Filed: 1976-04-01
Abstract: 1523021 Mixture strength control in carburetters NISSAN MOTOR CO Ltd 1 April 1976 [8 April 1975] 13239/76 Heading F1H The strength of air-fuel mixture supplied to an engine 10 is monitored and controlled by a sensor 40 located in the engine exhaust pipe 36 and sensitive to the concentration of a component of the exhaust gas, whose concentration is representative of the air-fuel ratio of the mixture supplied to the engine combustion chamber. An electrical signal generated by sensor 40 is compared with a reference signal (corresponding to the desired air-fuel ratio) and the resulting difference signal is applied to means 60 operative to control the supply of fuel to the engine. The means 60 may be an on-off solenoid valve controlling emulsify air to the main jet 22 and slowrunning jet 28 of a carburetter 16. Alternatively, the fuel flow can be directly controlled (not shown) and such control is applicable to fuelinjection engines. The signal is applied to the solenoid valve 60 as a train of rectangular pulses of constant frequency, but with a pulse width proportional to the difference signal (i.e. deviation from desired air-fuel ratio). When a stoichiometric air-fuel ratio is desired the sensor may be a CaO- stabilized ZrO 2  oxygen sensor with Pt electrodes. For richer than stoichiometric air-fuel ratios a ZrO 2  oxygen sensor with gold electrodes, a TiO 2  oxygen sensor or a CO-sensor (using SnO 2  or ZnO) can be employed. For leaner than stoichiometric air-fuel ratios a CoO oxygen sensor can be used. Reference has been directed by the Comptroller to Specifications 1431694 and 1450177.
