Patent GB-1375102-A (GB)
IPC: B25B23/145
Filed: 1972-01-20
Abstract: 1375102 Riveting; nut-runners CHICAGO PNEUMATIC TOOL CO 20 Jan 1972 [8 March 1971] 2757/72 Headings B3U and B3N A nut running tool having a combined nut running and crimping mechanism 27 and a drive means for operating said mechanism both for running down a nut and crimping the same, whereby the mechanism is operable in a first stage of operation to run down a work nut on a threaded member to a predetermined degree of tightness, and in a second stage of operation to crimp the nut. In operation compressed air from a hose 14 is passed into a piston chamber 42 via chamber 47, side port 46 and hose 45, to cause a piston 41 to slide a dog 34 into driving engagement with a drive nut 37. The air is also passed from the chamber 47 to a motor 13 which rotates the drive nut 37 via bevel gears 25, 26 and dog 34. Helical splines on the drive nut engage helical grooves of a travel wedge 54 so that rotation of the drive nut causes the wedge to move upwardly and frictionally lock its shoulder 60 against the gear 26. The bevel gears, drive nut and travel wedge thus rotate as a unit and act through a splined wedge head 58 to rotate a sleeve 57 so as to run down the nut to the required torque. The motor is then driven in the opposite direction to reverse the rotation of the drive nut 37 relative to the travel wedge 54. The wedge 54 is driven downwardly against the form of a spring 66 and simultaneously the sleeve 57 is restrained against a fixed surface 59. The downward moving wedge head 58 co-operates with jaws 68 via cam surfaces to pivot their ends 75 towards the axis of the sleeve and crimp the nut. The motor is stalled by resistance of the jaws to further pivoting when their backs stop against the wall of the sleeve. A pneumatic circuit (Fig. 9, not shown) is described for automatic actuation of the tool.

Title: Improvements in apparatus for cooling gases
IPC: F25J3/04
Filed: 1937-02-08
Abstract: 495,200. Refrigerating. LEVIN, I. H. Feb. 8, 1937, No. 3661. [Class 29] [Also in Group XXVIII] Cold - air machines.-Gases are cooled, especially for subsequent liquefaction and rectification, by expansion in the cylinder of an engine coupled without the use of a mechanical change-speed . device to an electric alternator. The primary winding of the alternator is located on the rotor and the secondary winding on the stator, while a speedregulating winding on the rotor is connected with the commutator which is itself connected through rockable brushes to the stator winding. Air to be liquefied passes through a heat exchanger 27 and is divided, part of the air passing through a second exchanger 28 and the expansion valve 30, while the other part passes through an engine 4 and joining the first part is led into the liquefying and separating column 29 ; the separated oxygen and nitrogen flow back through the exchangers. The engine has a mechanical emergency brake 13, the brake applying spring 14 being normally held off by a solenoid 15. The engine valves can be set for varying cut-off by a hand wheel 16 on a shaft carrying cams for this purpose. The engine is connected by belts and a pulley 18 to the rotor of the alternator. The commutator brushes are mounted on relatively rockable arms 23<1>, 24<1> adjustable by a hand wheel 25. The alternator may be started as a motor by closing the main switch 35 and the starting button 33 ; the rockers being set in the low-speed starting position with pilot contact 31 bridging terminals 32, circuit is made through the energizing coil 36 of the primary circuit contactor 37 and across the secondary thermal over-current relay 38 and the stopping and starting buttons 34, 33 ; the contactor is thus closed, and current passes to the slip-ring brushes 20 and the primary winding on the rotor. Ammeters 39, 40 are provided in the primary and secondary circuits. On overloading, the relay 38 will open the circuit; the rotor will then be driven by the expansion engine, while the braking of the circuit allows the brake 13 to be applied, preventing excessive speed. The brake solenoid 15 may be replaced by an electric warning horn 41 in a switchcontrolled circuit. Specification 469,940 is referred to.
