The beam may also be used for the interferometric measurement of the position of the parts. Two of the bearings 7, 8, are adjustable horizontally and vertically, the other two bearings 9a, 9b are adjustable vertically only. The column 10 is mounted on the bearings between which is suspended a detector flange 11 on ball joints and a spherical pivot to enable it to move relative to the bearings. Mounted on the detector flange 11 are detectors 12, 13 in a tube 57 and a detector in a tube 89. A light source 16 has its beam split to form beams R1, R2 to define an x-z plane. The detector flange 11 also carries a light source 50 which is split into beams R3, R4 to define a y-z plane for the vertically movable slide 19. A spindle arm 27 is mounted to the slide 19 similar to the mounting of the column 10 to the slide 6. The drill slide 29 has an end face maintained in the x-y plane by means of bearings 30, 31 which are ajustable horizontally and vertically, and bearings 32 apply a torque to the slide 29. The detectors include photo-diodes arranged in pairs or a quadrant arrangement.

Title: Take-down and Tension Device for a Circular Knitting Machine
IPC: D04B15/88
Filed: 1979-04-23
Abstract: A circular knitting machine, particularly a double-cylinder knitting machine for the manufacture of sock goods, has a take-down and tension device comprising vertically and independently displaceable rod- shaped take-down elements (6) arranged in a circle, the lower ends of which co-operate with a conical flare of an inner withdrawing tube (10) and the upper ends follow a horizontally arranged cam track (12) provided with a single actuating drive-on lobe. The actuating drive-on lobe is formed by a short ascending portion and an immediately following long slowly descending portion and is located in an area between knitting sections where the needles pass in their raised positions, with old stitches under the needle latches. The cam ensures a continuous tensioning effect along almost the entire circumference of the needle cylinder, as it is the case when using a pneumatic take-down device, and they simultaneously ensure identical conditions for stitch formation. The device in accordance with the invention can be used in single- cylinder circular knitting machines for the manufacture of sock goods too. <IMAGE>

Patent GB-2049174-A (GB)
Title: Photo-electric position or pressure measurement
IPC: G01D5/34
Filed: 1980-04-25
Abstract: Pressure-sensing apparatus has a pressure capsule 1, on which is mounted a movable plate 4 having an aperture 8. One edge 23 of the aperture defines, with a similar edge 24 of an aperture 9 in a fixed plate 5, a slit 6. The slit is illuminated to produce a diffraction pattern that is incident on the end 52 of a fibre-optic cable 55 located offset from the centre of the diffraction pattern. As the pressure changes, the movable plate is displaced, thereby altering the width of the slit and hence the diffraction pattern. A vibrating member 30 is located in front of the slit so as periodically to cover and uncover the slit at a frequency dependent upon temperature. The number of fringes displaced over the fibre end during each period of vibration is counted so as thereby to given an indication of the width of the slit and hence the pressure. <IMAGE>
