Patent GB-1279571-A (GB)
Title: Improvements in work transfer mechanisms
Inventor: WALLIS BERNARD JOSEPH
IPC: B21D43/05
Filed: 1970-01-14
Abstract: 1279571 Feeding metal workpieces B J WALLIS 14 Jan 1970 [13 March 1969] 1767/70 Heading B3W In a transfer mechanism for indexing workpieces through successive stations of a punching press, gripper bars 72, 74 are mounted on pairs of rods 68, 70, respectively, one rod of each pair being mounted on respective carriages 64 and 66. Racks (76) on the inner faces of rods 68 and 70 engage a common pinion (78), Fig. 14 (not shown), so that they move along parallel paths but in opposite directions. Carriages 64 and 66 are slidable on rods 60 and 62, respectively, and are interconnected by a shaft 44. Reciprocation of the shaft 44, through a drive cam 30, follower roller 40, lever 36 and clutch 42, reciprocates the carriages and thus moves the bars 72, 74 longitudinally. Rotation of the shaft through cam 30, follower 46, rack 52 on a slide 48, gear 54 and a clutch 56 moves the bars 72, 74 towards or away from work-engaging position. The throw of cam groove 32 is such as to produce a feed stroke a, i.e. the distance between punching stations of die 20. The throw of cam 34 is such as to move the bars a distance b. The cam 30 is driven by a shaft 28 in a housing 26. If the shaft is prevented from reciprocating a spring-urged detent 108 is cammed out of engagement with a notch 104 in the disc 94 of the clutch 42, the disc 94 rotating until notch 102 or 106 engages the detent 108, and the press is stopped by means of a cut-out switch (116), (118) and lever 36, Fig. 6 (not shown). If bars 72, 74 jam, a spring-urged detent (138) associated with the shaft 44 engages in a socket (140), Fig. 9 (not shown), disengaging the clutch 56 and an electrical device stops the press. In an alternative embodiment, Figs. 15-17 (not shown), carriage (64<SP>1</SP>) is stationary, the gripper bars sliding in blocks 204, 206. In a further embodiment, Fig. 18 (not shown) the drive housing is outside the carriage (64<SP>1</SP>) rather than between the carriages.

Title: Method and apparatus for measuring fibres
Inventor: BAKER LIONEL RICHARD
IPC: B05C17/02
Filed: 1968-01-12
Abstract: 1,246,099. Measuring diameters of fibres. SIRA INSTITUTE. 9 Jan., 1969 [12 Jan., 1968], No. 1956/68. Heading G4H. [Also in Division G1] The diameter of a fibre or wire is measured by directing a beam of monochromatic radiation on to the fibre to form a diffraction pattern and photo-electrically measuring the intensity of at least two portions of the pattern. A laser may be used to provide a coherent monochromatic beam 10 which is focused by lens 14 to form a diffraction pattern of the fibre 12 in a plane 18. A pair of adjacent photo-cells, connected in a differential arrangement, are located in a reference position several maxima away from the centre maximum 26. An increase (or decrease) in diameter of the fibre causes the selected maximum to move towards (or away from) the optical axis, resulting in a difference signal from the photo-cells indicating the sense of the diameter change. The output can control the rate of drawing of glass fibres when these are monitored by the apparatus. In an alternative arrangement, the photocells may be one on either side of the central maximum symmetrically disposed with respect to it. For large changes in diameter involving movement of a number of maxima at the detectors, counting circuitry may be provided. A number of fibres angled with respect to one another may be monitored, Fig. 3 (not shown), the mean diameter being measured. A movable photo-cell pair as in the Fig. 1 arrangement, or a pair of annular photo-cells, Fig. 3 (not shown), movable along the optical axis, may be used for this purpose. Alternatively a segment of the annular device may be used.

Title: Apparatus for impregnating porous materials with fluids
IPC: B27K3/02
Filed: 1976-01-22
Abstract: It permits the impregnation according to the double-vacuum, the vacuum-pressure and the Lowry processes, in particular for the protective treatment of solid wood and wooden materials with liquids for protection against biological and atmospheric damage. In known apparatus of this type, the time required for filling and emptying the impregnation cylinder is quite considerable, so that, apart from the variation in absorption due to the material, further variation in absorption results from the impregnating process itself. In the apparatus according to the invention, the cross-section of the connecting line (d) between the impregnation vessel (JG) and the supply vessel (VG) arranged above it is dimensioned in such a way that a period of only 6 minutes, preferably 4 minutes, is sufficient to completely fill the impregnation vessel. The same pipe dimensioning and therefore also the same times apply to the emptying of the impregnation vessel, for which a collecting vessel (AG) is arranged below the same, so that during both the filling and emptying of the impregnation vessel the free fall of the liquid can be utilised and thus work can be carried out in an energy-saving manner.   <IMAGE>
