Abstract: 977,107. Metal melting furnaces. BROWN, BOVERI & CO. Ltd. March 19, 1963 [March 21 1962], No; 10788/63. Heading F4B. Plant for refining metals comprises a cupola furnace, at least two tiltable induction furnaces, and a pivotable or displaceable pouring channel for alternately filling each induction furnace with metal which has been melted in the cupola. In a first embodiment, Fig. 1, molten metal is discharged from a cupola 1 via a channel 3 having a discharge hole 4 into a collector space 5 of a pouring channel 7 which pivots about block 6. The metal then pours down the inclined channel 7, through a discharge hole 8 and through an aperture 20 in the furnace cover 19 of one of two low-frequency induction furnaces 9 or 10 depending upon the position of pouring channel 7. Each of the furnaces 9, 10 comprises a body 12 with a pouring spout 14 below which is a spindle 13, mounted in supports 21, about which the furnace can be tilted by hydraulic cylinders 16. When in its basic position, the body 12 rests on a support 15. In another embodiment, Fig. 3, and Figs. 4, 5 (not shown), the transfer of molten metal from the cupola alternately into one of the two induction furnaces is effected by a laterally displaceable, arcuate pouring channel 23 which moves on a supporting block 24 provided with a spindle 25 which slides in two guide segments 26, 27 fixed to channel 23 so that the latter has two end positions which afford paths for molten metal between the end of the cupola discharge channel 22 and furnaces 9, 10 respectively. In yet another embodiment, Fig. 5, and Figs. 6, 7 (not shown), means are provided for lifting and lowering the induction furnaces 9 and 10 as well as tilting them.

Title: Improvements in stapling devices
IPC: B25C5/02
Filed: 1937-04-17
Abstract: 482,483. Stapling. PARROT SPEED FASTENER CORPORATION. April 17, 1937, No. 10979. Convention date, Jan. 2. [Class 89 (iii)] In a bench stapler, a cover member is hinged to the magazine so that it can be turned away therefrom to permit loading of, or access to staples in, the magazine. A base 11, which includes an adjustable anvil 19 adapted to be locked in either of two positions by a stud 29 on a leaf spring 30, is hinged at 43 to the body 12 of the stapler and normally is locked thereto by a latch 32 held by the spring 30. The staple magazine comprises a trough-like member 45 in which a rail 14 is held in fixed position by rivets 51, Fig. 7, and a tongue 61, so as to define a driver passage 69 between the front walls 46 and 67 of the trough and rail. A staple strip is slidably supported on the rail, as is a pusher 15 having flanged side walls interlocking with the sides of the rail. The trough also comprises a locking opening 40 for the latch 32 and ears 49 pivoting on the pivot pin 43. The body 12 is also pivoted on the pin 43 and comprises a rear part 16 and a sheath or front part 17 which are interconnected by a bayonet joint 79 and a pin 94. The part 17 constitutes a guide for the plunger 18, which carries a driver 96 operating in the passage 69. Normally, the body 12 is held, in a position enclosing the magazine, by a latch 131 slidable in slots 132 in the body and slots 135 in ears 48 on the trough 45. In this position, the lower edges of the sheath 17 are flush with the front edges 162 of the trough, while the lower edges of the part 16 are received within the side walls of the trough and overly the staples on the rail. The latch is held in locking position by the pusher spring 150. When the latch is moved forwardly, the body 12 may be swung away from the magazine, Fig. 3. The spring 150 then holds the pusher 15 at the rear of the magazine, permitting easy loading. When the body 12 is returned to closed position, cam surfaces of the ears 48 return the latch to locking position. A full-stroke mechanism comprises a bracket 84 secured in the sheath 17 and carrying slidably a latch member 100 which is urged forwardly by a spring 107. In the position of rest, the latch abuts the rear face of a lug 101 on the plunger 18. If the plunger makes a partial stroke, the latch moves forwardly above the lug, preventing a full return stroke of the plunger. If the latter makes a complete stroke, a cam surface 111 on it engages projections on the latch, moving the latter into a slot 103, so that it cannot obstruct the return stroke of the plunger. At the end of such stroke, however, shoulders on the plunger release the latch from the slot 103, permitting it to return to the rest position shown. The plunger is raised by a leaf spring 112 disconnectably associated with the plunger and the bracket 84.

Title: Improvements relating to inductive control of the steering of vehicles
IPC: G05D1/02
Filed: 1969-03-03
Abstract: 1,263,993. Leader gear systems. ROBERT BOSCH G.m.b.H. 3 March, 1969 [2 March, 1968], No. 11106/69. Heading H4U. In a system for controlling the steering of a vehicle in accordance with the electromagnetic field of a conductor arranged along the route of the vehicle, the vehicle carries a first pick-up coil 20, Fig. 1, positioned with its axis horizontal and transverse to the direction of travel and second pick-up coil 22 with its axis vertical and in front of the first coil, voltage induced in the first coil providing a phase reference for voltage induced in the second coil. The output of the reference coil 20 is supplied via tuned amplifier 21 to a trigger circuit 28 which supplies a squarewave output to AND gates 30 and 31. The signal coil 22 via tuned amplifier 23 controls a trigger circuit 29 supplying a square-wave signal to AND gate 30 and this signal inverted to AND gate 31. The arrangement is such that if the signals from the coils 20, 22 are in phase the vehicle is deviating to the left and the gate 30 supplies a signal via R.C. stage 32 to a trigger 34 to provide an input to an AND gate 36. If the outputs of the coils are in antiphase the vehicle is deviating to the right and an output is supplied via gate 31, R.C. circuit 33 and trigger 35 to an AND gate 37. When the vehicle is on course there is no output from coil 22 and neither gate 30 nor 31 will open. A control device 63 switches off the vehicle driving motor if the vehicle deviates from the route by an excessive amount. The tuned amplifiers may be switched by relays to operate at different frequencies, Fig. 9 (not shown), so that the vehicle may follow conductors energized by different frequencies. A pulse width control device 38 supplies pulses via whichever gate 36 or 37 is opened to control the direction and in accordance with the pulse width the number of revolutions of the steering motor 40. Narrow pulses from a multivibrator 39, Fig. 10, charge a capacitor 41 which blocks a transistor 49 until the capacitor is discharged via a variable impedance 50 which may be a transistor, the impedance 50 being controlled by the output of coil 22 via amplifier 23 and terminal 45 so that its value is reduced as the output of amplifier 23 increases and vice versa. By this means widthmodulated pulses are supplied via terminal 47 to the appropriate gate 36 or 37. An output from trigger 34 or 35 is differentiated at 54 and supplied to the base of transistor 49 so that initially a short correcting pulse is provided, the fine correction then taking place as described.
