Title: Improvements in and relating to hydraulically operated machinery
IPC: B66B1/04
Filed: 1925-08-31
Abstract: 259,354. Knutsen, J. B. M. Aug. 31, 1925. Fluid-pressure apparatus.-In hydraulic lifts, cranes, &c. means is provided for allowing the load to descend at a constant speed. The delivery pipe of a multicylinder constant volume hydraulic pump is connected to the pipe 7, Fig. 2, and the hydraulic ram, &c. is connected to the end 8 of the pipe 10. A spring-controlled valve 11 in the pipe 10 controls the opening to a passage 12 which ends in a fish-tail nozzle 17 projecting slightly into a cylinder 18, Fig. 1. The hollow piston 19 is controlled by an adjustable spring 22, and is formed with a flat 20, Fig. 5, in which is cut a triangular slot 21. The passage 37 leads to exhaust. A cylinder 24 coaxial with the cylinder 18 and containing an independent piston 25 is entered by a plunger 26 and is connected by a pipe 31 to the pipe 10. Ports 27, 27<a> at the ends of the cylinder 24 open into a passage containing a valve 28 and connected to exhaust by a pipe 38. The valve 28 is actuated by a solenoid against an adjustable spring. A narrow passage 13 in the valve 11 connects the pipe 10 to a chamber 14 which communicates with the exhaust by a spring-controlled valve 15 operated by a solenoid 16. A bye-pass passage 32 is provided on the pump side of the check valve 9 on the delivery pipe 7 and its opening is controlled by a solenoid actuated valve. When the motor is cut. off, the load is held by the valve 9. When it is desired to lower the load. the valve 15 is opened, fluid escapes from the chamber 14 to exhaust and the valve 11 opens. The opening of the latter valve allows the fluid held up by the valve 9 to issue through the nozzle 17, slot 21 and openings 36 in the piston 19 to the passage 37 leading to exhaust. At the same time the plunger 26 is moved upwards and displaces the piston 19 until the, area of the nozzle 17 has been reduced to the desired extent by the movement of the triangular slot. If the sizes of the nozzle 17, slot 21 and plunger 26, and the strength of the spring 22 have been suitably proportioned, any load will be lowered at the same speed. If the valve 28 is actuated to interrupt communication between the ports 27, 27<a> and to connect port 27 with the port 28, the piston 25 will rise and engaging the plunger 26 will push the piston 19 to its highest position, thus reducing the area of the nozzle 17 to a minimum. The load will now descend at a reduced speed and accurate stopping will be facilitated. If an accurate stop is desired when the load is being raised, the speed of ascent is reduced by allowing a part of the fluid being pumped to issue through the bye-pass 32. The solenoids actuating the valve 28 and the valve controlling the bye-pass may be energized by cams and switches provided in the lift well.

Title: Turret assembly
IPC: B23Q16/10
Filed: 1971-04-19
Abstract: 1335241 Turret lathes; indexing WARNER & SWASEY CO 19 April 1971 [9 March 1970] 22113/71 Headings B3B and B3T In a turret lathe means is provided for operating the turret to successively present each one of a plurality of tools, carried by the turret, to a working position and which comprises an actuating shaft 76 which is supported in a turret carrier 32 and carries a cam 58 and the operating arm 154 of a Geneva mechanism 136. The rotation of the shaft 76 causes the cam 58 to displace a wedge member 56 transversely to the turret shaft 64 which permits axial displacement of the turret shaft 64 by the action of spring 60. The axial displacement of the turret shaft moves the turret 18 to disengage the interengageable teeth 34, 36 between the turret 18 and carrier 32 thus releasing the turret from its clamped position against the carrier 32. Continued rotation of the shaft 76 subsequently engages the arm 154 with the Geneva wheel 140 which indexes the turret to bring a fresh cutting tool into its operative position, the cam 58, due to its profile retaining the wedge member 56 in its displaced position to maintain disengagement between the teeth 34, 36 while the turret indexing is effected. Further rotation of the shaft 76 subsequently permits retraction of the wedge 56 and hence clamping of the turret against its carrier by engagement between the teeth 34, 36. The above operation is effected each time it is required to index the turret to present a fresh tool in the operating position. Although in the embodiment described the actuating shaft is shown as being manually operable by way of handle 44, the shaft may alternatively be power operated by way of a motor. Also, the mechanism may be actuated in both directions so as to permit indexing of the turret in either direction of rotation.

Title: System for identification of burst signal phase in pal television  system
IPC: H04N9/465
Filed: 1972-05-12
Abstract: 1336698 Colour television SONY CORP 12 May 1972 [14 May 1971] 22422/72 Heading H4F A PAL colour television receiver includes a one (or 3 or 5...) line delay line 19 and a switch 20 operated at the end of each line period and controlled so as to pass only received lines which have a positive (R-Y) modulation axis and the corresponding bursts, which are fed to demodulators 22 and burst gate 27, incorrect mode of operation of the switch 20 at the start of reception being corrected by a circuit 26. Circuit 26 uses the fact that for periods of nine lines, which include the vertical synchronizing intervals, the bursts in a PAL transmission are missing, and the bursts immediately preceding and following each such interval are at +135 degrees phase. Thus there is a ten-line interval between bursts of + 135 degrees phase, but a twelve line interval between bursts of - 135 degrees phase. Due to the action of one-line delay line 19 these intervals in the signal from burst gate 27 are nine and eleven lines respectively. Circuit 26 compares the length of a square wave pulse whose leading and trailing edges coincide with the start and finish of each such interval, with a square wave pulse of ten lines duration from a multivibrator triggered simultaneously with the other square wave pulse. If the pulse from the multivibrator is the shorter, flip-flop 25 is caused to change switch 20 over to its other (desired) mode. The subcarrier oscillator is caused to operate at the phase of the bursts from burst gate 27, phase-shifters of 45 and 90 degrees being included in series between the oscillator and demodulators. A colour killer 32, automatic chroma control 31 and colour control between switch 20 and amplifier 21 are included.
