Title: Improvements in cutting heads for cropping machines
Inventor: JONES HAROLD
IPC: B23K7/00
Filed: 1964-09-24
Abstract: 1,125,763. Cutting by fusion. BRITISH OXYGEN CO. Ltd. 15 Sept., 1965 [24 Sept., 1964], No.39012/64. Heading B3V. A cutting head for a cropping machine includes a carriage on which a support is mounted for free movement about two axes at right angles, the support carrying a burner and a work contacting probe, the movement serving to protect the burner from damage due to contact with a workpieoe. The work contacting probe 20 for a flame or plasma torch cropping machine is mounted in collars 74 and 76 forfree vertical movement and is supported about an axis 82 extending transversely to the longitudinal axis of a workpiece W. A cutting burner 18 is mounted beside the probe and is pivotable about a separate transverse axis 60. Both the burner and probe assemblies project from a fixed support 10, Fig. 2, by way of a pivot 22 and adjusting screw 24. Relative rotation of the parts 16a and 16b due to contact between the probe and workpiece, as the probe approaches the workpiece and pivots anti-clockwise (Fig. 1), causes contacts 90 and 92 to be closed to increase the speed of travel of the burner to its normal value. Such contact between the probe and a workpiece causes the probe to pivot anti-clockwise, as seen in Fig. 2, about the axis 82 to cause a supporting arm 80 and bracket 84 to turn about an axis 85. This causes a rod 40 to be pulled to the left to actuate a control switch 46 which can initiate a starting sequence for the burner. Tilting of the sector 42 caused by contact of its surface 58 by an oversize workpiece can be used to initiate a warning signal, if desired. Clockwise pivotal movement of the probe can freely occur without operating the switch. Pivotal connections between the supporting arm 80 and bracket 84, and between the parts 16a and 16b of the switch assembly prevent accidental damage if the apparatus is inadvertently struck by a workpiece. The burner 18 is similarly protected from impact with a workpiece by a counterbalanced sector 42 attached to the burner for movement about the axis 60. The sector will be struck first and will rotate the burner out of the path of the work.

Abstract: 1364005 Measuring shaft rotation electrically CHELYABINSKY POLITEKHNICHESKY INSTITUT IMENI LENINSKOGO KOMSOMOLA 24 Aug 1972 39520/72 Heading G1N An apparatus for converting a shaft rotation angle to an A.C. voltage phase comprises an angle resolver 1 producing an electrical signal dependent on the angular position of a shaft (supplied to a mechanical input 2); a phase splitter 3 having first and second terminals for providing or receiving two voltages differing in phase which first and second terminals are connected to respective terminals of the angle resolver and a modulator, constituted by an inverter 6 or commutator 4, arranged periodically to invert the phase of at least one of the two voltages applied to or received from the resolver. In the Fig.1 embodiment the phase splitter 3 has a first output directly connected to an electrical input of the angle resolver and a second output of the phase splitter (in phase quadrature with the first) is connected to another electrical input of the resolver through the phase inverter 6. In the Fig.2 embodiment the modulator is a commutator 4 which inverts both outputs of the phase splitter relative to the inputs of the angle resolver. It is stated that the phase of the output voltage from the apparatus is the sum of a variable component in linear relationship with the angle of rotation of the shaft and of a constant error caused by the non-orthogonality of the voltages from the phase splitter. In alternative embodiments Figs.3, 4 (not shown) two electrical outputs are taken from the angle resolver and fed to two electrical inputs of the phase splitter, in the Fig. 3 embodiment one of the outputs is periodically inverted by phase inverter 6, in the Fig. 4 embodiment both outputs are periodically inverted by the commutator 4. A phase servo-system Fig.7 (not shown) utilizes at its input and output apparatus as set and above to convert input shaft 2 rotation angle and output shaft rotation angle to A.C. voltages which are fed to a comparator (20) from which an error signal controls servo-motor (22) coupled to the output shaft. Practical details of the resolver, phase splitter are illustrated in Figs. 5, 6 (not shown).
