Abstract: 545,007. Discharging static from vehicles. UNITED AIR LINES TRANSPORT CORPORATION. July 15, 1940, No. 11733. Convention date, May 10. [Class 79 (iii)] [Also in Groups XXXIII, XXXV and XXXVI] Apparatus for discharging static from a vehicle comprises an electric conductor having one end connected to the vehicle and the other carried by a projector mechanism normally retained in retracted condition, means being provided within the vehicle to release the mechanism to eject the conductor which then acts by brush discharge to dissipate the charge on the vehicle. Two such devices are shown mounted side by side in an aircraft, one being held in reserve against the failure of the other. Each comprises a removable container 11 or 12 secured in position and electrically grounded by locking members 15. A sliding plunger 21 is held against the compression of a spring 25 by a wire 32 connected to a trigger 31 which is normally held fixed by a fusable wire 33. The plunger has a head 22 provided with grooves to engage the cables 41 of a wind cone 42 having a ring 44 which flexibly engages projections 45 on the container. The cables 41 are connected to a cable 42 united to the end of a thin conductor 37 united in turn to a thicker resistor 36 both of which are wound around fixed rods 34. The forward end of the resistor is grounded by connecting it to a pillar 39 on an end plate 17. The wire 33 is connected to an insulated contact 52a electrically connected to a sleeve 52 in contact with a brush 54, and a concentric sleeve 5'1 contacting with a brush 53 is connected to a normally open switch contact 50 co-operating with a spring plate 49. The rear end of the container is closed by a parchment disc 47 held in position by a ring 46. To release the conductor 37, current is sent through the wire 33 which fuses and releases the trigger 31, whereupon the spring 25 projects the plunger 21 until it is arrested by a stop after rupturing the disc 47. The wind cone then withdraws the conductor 37 and resistor 36 the last turn of the resistor being drawn against the spring plate 49 to cause it to engage the contact 50. Test circuits with signal lamps indicate whether the wire 33 is intact and the device consquently not projected, or whether the switch 50 is closed and the device consequently in use. The resistor 36 comprises strands of jute or hemp impregnated with colloidal graphite, such as that known under the Registered Trade Mark "Aquadag", and subsequently dried, the completed resistor having a waterproof cover of rubber.

Title: Means for stripping ingots from bolster plates or the like
Inventor: JONES JOHN FREDERICK ROBERT
Filed: 1961-04-04
Abstract: 928,098. Ingot strippers. WALTER SOMERS (MATERIALS HANDLING) Ltd. April 2, 1962 [April 4, 1961], No. 11904/61. Class 83 (1). A device for stripping ingots from a bolster comprises a box-like holder 20 open at its upper and lower ends. A lifting member 30 of inverted U-shape has limbs 33 which straddle the holder 20, each limb being pivotally mounted at its lower end by a pin 34 to one end of a foot lever 35. Each foot lever is pivotally mounted, intermediate its ends, to the holder 20 by pin 37 and at its other end by a support bar 38 welded to the holder side 21. A downwardpushing U-shaped member 40 is positioned within the lifting member 30 and is provided with an upstanding push rod 42 which engages a push rod 15 associated with crane lifting tackle 10. Depending limbs 43 of the pusher member 40 straddle the holder 20 but lie inside the limbs 33 of the lifting member, said limbs 43 being provided with guide bars 44 permitting relative vertical movement between members 30 and 40 but preventing undue transverse movement. Associated with members 30 and 40 is an automatic locking and releasing device 47 of known construction similar to that referred to in Specification 642,100 which is referred to. The stripping action is effected by placing the holder 20 over the ingot with the device 47 locking members 30 and 40 together. The pusher member 15 of the crane tackle 10 exerts a downward pressure on the push rod 42 which is conveyed to the holder 20 at the pivot part 45 and simultaneously a lifting effort is applied to raise the member 30 which results in rocking the foot levers 35 about a fulcrum 36 and tipping the holder about a fulcrum 29. Continued upward movement of the lifting member in co-operation with the device 47 causes pads 24, 25 of upper and lower jaws 22, 23 respectively to bear against sides 26, 27 of the ingot 16 causing said ingot to be tipped about a lower corner thus stripping the lower face thereof from the bolster 17.

Abstract: 234,103. Kutzbach, K. May 19, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Steam-engine and like indicators.-Comprises a method and apparatus for indicating the average pressure or average power of piston engines characterized in that for each working space one terminal voltage is made dependent on the one hand on the piston pressure and on the other hand either on the sine of the crank angle or on the momentary piston speed. A voltage E<1> is applied to the points 1, 2 of a resistance 5, Fig. 2. the resistance 5 are a stationary contact 7 and a contact 6 moved by a crank and guide mechanism 8, 9 from the engine. The contact 6 is thus moved proportionally to the sine of the crank angle "a" so that the potential difference E2 across points 3. 4 is proportional to sine a. The contact 7 is adjusted so that this potential difference is zero when a is zero. In a similar arrangement. Fig. 3, a contact 6<1> is moved by a steam engine indicator 10 so that the potential difference E3 is proportional to E2 x p where p is the pressure of the working fluid. If both circuits are connected in series by connecting the terminals 1<1>, 2<1> of Fig. 3 to the terminals 3, 4 of Fig. 2 the potential difference E3 will be proportional to E1 x p x sin a. In a modification the voltage is similarly varied by varying the resistance in one arm of a Wheatstone bridge. In a further form a coil is rotated in a uniform magnetic field and generates a current proportional to the speed x sin a or the coil may be reciprocated by a crank and link mechanism to cut across a magnetic field.

Abstract: 858,314. Pipe couplings. BRIEDEN, K. W., and KUHME, E., [trading as MASCHINENFABRIK K. BRIEDEN & CO.], April 22, 1958 [April 25, 1957], No. 12674/58. Class 99(1). In a pipe coupling, e.g. for pipes of a pneumatic stowage system for mines, coupling members 6, 7 are moved to engage tightly pipes 1, 5 by the action of a wedge surface 12 on a wedge member when the latter is driven in one direction and to loosen the coupling by the action of a further wedge surface 13 on the same wedge member when the latter is driven in the opposite direction. As shown, the members 6, 7 comprise two half-yokes pivotally connected by a pin 8, the half-yoke 6 being provided at its free end with a tongue 9 which passes between prongs 10, 11 of the forked end of the half-yoke 7 when the coupling is assembled, openings being provided in the tongue and the prongs for reception of the wedge member. The wedge surfaces are disposed in different planes on the wedge member and are unequally spaced from the axis of the pipes. When coupling the pipes the wedge surface 12 engages abutment surfaces 14, 15 in the tongue 9 and the prongs 10, 11 respectively whereby the half-yokes 6, 7 are drawn tightly on flanges 2, 4 on the pipes 1, 5 respectively, locking of the wedge member being provided by a spring loaded plunger 20 engaging a recess 19 in the member. When uncoupling the pipes the wedge surface 13 engages abutment surfaces 16, 17 in the tongue and prongs respectively causing the half-yokes to be moved to loosen the coupling. A lug 18 adapted to abut against the prong 10 prevents the wedge member from being withdrawn completely from the coupling.
