Title: Improvements in or relating to feed control mechanism for automatic lathes
Inventor: JAUCH KURT
IPC: B23B7/02
Filed: 1951-12-10
Abstract: 723,117. Lathes. SCHMID, R., SCHMID, C., SCHMID, J., and BRUNNEMANN, F. W., [trading as AUTOMATENWERKE STEINHAEUSER]. Dec. 10, 1951, No. 28833/51. Class 83(3). Feed control mechanism for automatic lathes, particularly those with sliding headstocks, having a main control shaft which rotates once during the production cycle of a workpiece is characterized by (a) interchangeable individual feed-control cams carried by their own control shafts and driven by a friction clutch from the main control shaft at an adjustable speed ratio, the cams controlling longitudinal and/or facing feeds; (b) stops which rotate with the cams and by which the cams may be brought to rest while traversing or facing operations are performed and (c) dogs on the main control shaft for disengaging pawl means holding the said stops when the secondary operations are completed, the speed ratio between the feed cams and the main control shaft being such that the former rotate once during each rotation of the latter despite the idle periods due to the stops and pawl means. The drive for main control and auxiliary cam-shafts 8 and 32, 132, respectively, is derived from the work spindle 1 through a change-speed box 3 and belt-gearing 4. The shaft 8 is driven through worm gearing 7 from the shaft 5 and gearing 6. The drives and control gear for the longitudinal and transverse feed movements are similar. For longitudinal feed the shaft 5 drives through change gears 21 and worm gearing 22, the outside part 23 of clutch 24 which is adjustable for slip through a spring 28 and which may be engaged and disengaged by a lever 27. The inner shaft 29 of the clutch drives, through a pinion 30, a gear integral with a dog-drum 39 forming part of a control device for limiting the rotation of the hollow auxiliary cam-shaft 32 which carries a cam disc 35 for, the longitudinal feed. This cam disc engages a follower 36 connected to the lathe slide. A further cam disc 144 moves this slide and is secured to the end of a shaft which passes through the hollow shaft 32 and is driven by gearing from the hollow auxiliary cam-shaft 132 carrying the dog-drum 138 and cam disc 135 for the transverse feed. A similar interconnection with a cam disc 44 on the end of shaft 43, driven by gears 41, 42 enables either the transverse feed to be superimposed on a longitudinal feed or vice versa, thus enabling conical portions to be cut on any desired portion of a work.

Abstract: 1344959 Shaping yarn package carriers R CROTTI 21 June 1972 [25 June 1971] 29075/72 Heading B5A [Also in Division B8] Yarn package carriers 1 of plastics material which have been axially compressed following a yarn treatment operation, are reformed to their original length by heating, stretching and then cooling them. Apparatus for this purpose comprises endless conveyers 4, 9 composed of hinged plates 5, each supporting a device 6 which clamps the end of a carrier; thus each carrier is clamped between a pair of devices 6. During conveyer movement the clamped carriers are taken through a heating station comprising electric heating elements and fans, after which the clamps of each device 6 are axially separated to stretch the carrier which is then cooled by a fan. The lower clamp is disconnected from the treated carrier which is conveyed by the upper clamp to a position beyond the end of the lower conveyer where it is released. Each device 6, Fig. 5, includes a sleeve 16 secured to a conveyer plate in which an inner sleeve 19 is slidably mounted. One end of a carrier is clamped between a ring 29 on the sleeve 19 and a number of annular sectors 30 which are forced radially outwardly against the action of a spring 32 by pins 31 engaging a cam portion 27 on a stem 25. Axial movement of the latter by cam surfaces 35 open or close the clamp, whilst axial movement of the sleeve 19 by cam surfaces 34 either brings the clamping means of opposed devices 6 of a pair towards or away from one another. The carriers are initially loaded and clamped to a device 6 on the lower conveyer.

Title: An improved apparatus for measuring the internal power absorption by materials when subjected to oscillatory strains
IPC: G01N3/38
Filed: 1935-10-23
Abstract: 448,667. Testing physical qualities of materials. SIEMENS & HALSKE AKT.- GES., Siemensstadt, Berlin. Oct. 23, 1935, No. 29259. Convention date, Oct. 26, 1934. [Class 106 (ii)] A test piece is subjected to oscillatory strains and the phase displacement between two cross-sections removed from each other along the test piece measured electrically to serve as a measure of the internal power absorption of the material. The test bar 1 is fined at one end 2. On the free end 3 a double-pole magnet armature 4 is fined and is arranged inside a double pole magnet system 5, having a winding 6. The armature 4 carries a steel tube 8 surrounding the bar 1 and carrying on its free end a coil 9 disposed opposite to a magnet 11 fixed to the bar. The coil 9 is so formed that the amplitude of the potential produced by the magnet 11 is proportional to the relative amplitude of oscillation between the coil 9 and magnet 11. In circuit with the coil 9 is a direct current instrument 13 and an externally excited synchronous rectifier switch 12. An exciting winding 14 for the rectifier 12 is connected to the secondary side of a phase shifter 15 the primary side of which is connected to the winding 6. This winding 6 is excited from a source 7 of alternating current. At first the oscillations are kept small so that stresses in the bar are below the elastic limit, and the cross-sections all along the bar oscillate in like phase with each other. An alternating current or like phase is excited in the coil 9. If now the phase shifter 15 is so adjusted that the measuring instrument 13 reads zero, there will flow through the instrument portions of like amount of each half wave of the current impulse induced in the coil 9 and these cancel each other. As the oscillations are increased, a point is reached, where a phase displacement occurs between the crosssections under comparison and the instrument 13 shows a deflection. This deflection depends not only on the phase displacement, but on the frequency and amplitude of the oscillations, but correction factors for this may be used or a record is obtained of the amplitude of oscillate and phase difference in a single recording.

Class 100(2) Type-bed cushioning apparatus for a cylinder printing machine comprises an air compressor coupled to the bed drive, and consisting of an oscillating vane 11 in a closed casing 12. As shown the bed 1 is driven by an oscillating shaft 9 through a gear 4 and rack 3, and the vane 11 is fixed to the shaft 9 and supported by a ring 10 so as to oscillate through about 270 degrees in the casing 12 which has a cross piece 13 the top of which forms a seal with the ring 10; non- return valves 14 are situated at the bottom of the casing. The casing 12 may have a single ventilating slot 21, for a stop- or swinging-cylinder press (sinusoidal type bed motion), or two slots at, say, the 10 and 2 o'clock positions (Fig. 3, not shown), for a single or two revolution press (uniform type bed motion with short reversing movement). If the shaft 9 oscillates nearly 360 degrees or more for driving purposes, a reduction gear is inserted between it and a separate shaft for the vane 11.
