Title: A method and apparatus for performing thread and like machining operations
IPC: B23G1/46
Filed: 1962-08-23
Abstract: 1,015,173. Thread-cutting. J. B. BARBEAU. Aug. 23, 1962, No. 32427/62. Headings B3B and B3N. [Also in Division F2] A method of machining consists in storing energy obtained from rotation of the workpiece subsequently to be used to increase the speed of the tool. A screw-threading or tapping device for use in the method is housed in a casing 27 threaded for axial adjustment on a mounting portion 25 and clamped by a ring 28, the adjusted position being indicated by graduations on the casing. A steel, tungsten or lead flywheel 36 is mounted on the portion 25 and carries an axially-adjustable hub 48. The tap 22 is held in a collet 51 clamped by screws 53 in a head 52. The collet has an extension to receive a squared end of the tap. The head 52 is movable axially within a front bearing 55, movement being limited by a shoulder 152. The head carries four planetary friction rollers engaging the casing 27 and the hub 48, and also carries a clutch member 170 to engage a clutch 173 which can be threadedly adjusted on the flywheel 36 and secured by a screw 74. In use, the easing 27 is clamped in a lathe turret which is advanced towards the rotating work. The tap 22 is engaged and rotated by the work and axial feed pressure causes the rollers 66 to convey rotation to the hub 48 and hence the flywheel. Consequent retardation of the tap causes the thread to be cut. When the hole has been tapped, the turret is withdrawn causing the flywheel to rotate the tap through the clutch 170, 173, the rollers 66 being moved out of driving engagement.

Title: Circuit Arrangement for the Clock-Pulse Control of a Circuit Element such as a Bistable Trigger Circuit
IPC: H03K3/28
Filed: 1966-07-20
Abstract: 1,157,795. Transistor pulse and bi-stable circuits. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 20 July, 1966 [27 July, 1965], No. 32549/66. Heading H3T. In an arrangement for controlling a circuit element (e.g. bi-stable circuit A) by the charging and discharging of a capacitor 14 as the result of a pulse at E 1  and a clock pulse at T 2 , the charging of capacitor 14 is delayed so as to prevent false operation due to spurious delay in the tuning of clock pulse T 2 , but discharge of 14 is not delayed. The pulse 23, Fig. 4, at E 1  may be obtained from a previous stage B, controlled by clock pulse T 1 , via AND gate 25 and OR gate 26. Capacitor 14 and diodes 22, 18 should delay the triggering of circuit A by one period of clock pulse T 2 . If clock pulses T 1  and T 2  were simultaneous, diode 22 would prevent capacitor 14 from charging to the voltage at E 1  until the end of the negative-going clock pulse T 2 , but if clock pulse T 2  is delayed with respect to T 1  and 23, charging of capacitor 14 is delayed by a delay line, diode or choke 30. The subsequent discharge current (at t 1 <SP>1</SP>) is then insufficient to trigger bi-stable circuit A, provided the spurious clock delay (t 1 <SP>1</SP>-t 1 ) is shorter than the delay (#t v ) imposed at 30. Capacitor 30 is again prevented from charging until the end of clock pulse T 2  when it slowly charges, as shown at P 1 . Clock pulse T 2  ends at t 3 <SP>1</SP> so that capacitor 14 finally discharges via diodes 16, 32 and 22, thus turning off transistor 1 and setting the output 7 of the bi-stable circuit A. The circuit is reset by a further pulse at E 2  after a further delay of one period of clock pulse T 2 . In Fig. 5 (not shown) chokes 30 and 31 are replaced by a single choke in series with bias supply + U v .

Title: Improvements in or relating to hydraulic presses
Inventor: VOGT PAUL
IPC: B30B15/16
Filed: 1959-09-25
Abstract: 882,514. Cutting-machines. PAPIERVERARBEITUNGSMASCHINENWERK PERFECTA VEB. Sept. 25, 1959, No. 32653/59. Class 31 (1). [Also in Group XXIX] An hydraulic press system for fast cutters, comprises a pump 1 which is connected by valves 5, 25 to the press cylinder 12, and an hydraulic storage cylinder 21 connected to the main control valve 5 so that the press cylinder is filled by the storage cylinder in preparation for connecting the pump to the cylinder for the full-pressure operation of the press plunger 18. The cylinder is connected by a line 30, the valve 25, and a line 28 or 29 to the valve 5 which communicates with a pressure line 4 from the pump and a line 33 connected to a reservoir 2. A line 19 is joined to the line 4 and supplies fluid pressure to the bore 16 of a stationary piston 13 in the bore 17 of the plunger 18, which may be connected to a cutter for cutting paper or the like. A space 12a above the plunger is connected by a line 11, the valve 5, and a line 20 to the storage cylinder 21 which has a piston 22 connected by a line 23 to an air, gas, oil or like pressure source. The cylinder 21 is also connected by a line 31 to the line 28. In operation, with the valves in the position shown, fluid pressure from the pump passes to a space 12b at the lower end of the plunger 18 and to the bore 16 of the piston 13. Since the area F1 of the press piston is greater than the area F2, the plunger moves upwardly, fluid in the space 12b passing through the line 11 and valve 5 to charge the cylinder 21. When the cylinder is fully charged, the excess fluid passes through a pressurerelief valve 15 to the reservoir. When the valve 25, which is a preliminary control valve, is operated, the space 12b is connected to the exhaust line 33 and pressure in the bore 16 of the piston 13 moves the plunger 18 downwardly, the space 12a being filled with fluid from the storage cylinder 21. When the main control valve 5 is actuated by means of a magnetic slide 10, the pressure from the pump is immediately effective in the chamber 12a which has been maintained full by the storage cylinder 21.
