Abstract: 1,205,401. Punching; hold-downs. HOUDAILLE INDUSTRIES Inc. 6 Nov., 1967 [14 Nov., 1966], No. 50421/67. Heading B3W. A toggle-operated hydraulic punch comprises a ram 15 detachably connected to a punch tool 22 by engagement of a T-head 33 on the punch head 31 with a T-slot 32 in an adapter 30 screwed to the ram. A detachable head 14 screwed to the upper arm 12 of a C frame supports the toggle linkage 18 and an hydraulic actuator 19 is pivotally mounted in a bracket 56 on the head by means of a trunnion 55. An upper tool holder 16 detachably secured to the head (by means not shown) and adjustable relative to it supports an annular hold-down 24, surrounding the punch tool, which is actuated to clamp a workpiece 23 against a die 13 by a pair of pistons 36 engaging members 62 secured to ears 61 on the hold-down 24. Hydraulic fluid is supplied to each piston through a tubular rod 37 and the piston is retracted by engagement of the ears 28 on the ram 15 with an adjustable abutment 38 on each rod. When not engaged by the piston the hold-down is raised by springs 60 acting between the holddown and the heads of screws 59 secured to the holder 16. Detachment of the tool holder from the head 14 automatically disengages the T-slot connection between the ram and the punch tool and the punch tool is prevented from falling out of the hold-down when this occurs by yieldable support means 67 comprising a U-seotion member 68 abutting against a recess in the punch body 64 and a shoulder 69 on the hold-down and urged downwardly by springs 70 which also act against a ring 71 screwed to the punch body 64.

Title: Lasers

Filed: 1972-11-02
Abstract: 1412473  Lasers L E DAHLSTROM 2 Nov 1972 [5 Nov 1971] 50552/72 Heading H1C A laser resonator M, M<SP>1</SP>, Fig. 1, contains a polarization-selective output coupler P which, in conjunction with retardation elements R1, R2, R3 and a Kerr or Pockels cell C, provides an output non-linearly related to the generated radiation intensity within the resonator. As described, an output is only obtained when the generated radiation has a sufficiently high intensity, but the converse may apply. Q- switched and mode locked output pulses are obtainable. As shown, radiation from an active medium LR such as neodymium glass becomes plane polarized in its passage through a Glan prism P and is then elliptically polarized by a retardation element R1. The ellipitical polarization is rotated in its passage through the cell C, after which it passes through retardation elements R2 and R3 to a resonator mirror M. The radiation is reflected by the mirror and passes back to the Glan prism through R3, R2, the cell C arid R1, in that order. With a suitable length of cell L, and an anisotropic content such as carbon disulphide or nitrobenzene having a refractive index determined by the intensity of incident radiation, the reflected radiation is plane polarized on arrival at the Glan prism if the intensity is low and elliptically polarized if the intensity is high. Consequently low intensity radiation passes directly to the active medium, while high intensity radiation is deflected out of the resonator. The converse is also possible by suitable choice of component parameters, in which case the output radiation is obtained after a further reflection at reflector M<SP>1</SP>. The laser may be Q switched by a rotating prism or by a saturable cell (not shown). The retardation element R3 may be omitted by using a prism RP as reflector M, Figs. 2a-2c, the prism having a roof angle which may be equal to, greater, or less than 90 degrees. In Fig. 2d a further prism replaces the remaining retardation elements. The operational characteristics of the arrangement may be determined by the measuring system shown in Fig. 4 in which the radiation intensity in the resonator is indicated by the output through a resonator mirror M<SP>1</SP>, this output being reflected towards a photodetector PD where it is compared with the Glan prism output. Filters F1 and F2 are respectively provided in the two output paths. In the system shown the retardation plates R1, R2 form windows for cell C and a bleachable Q-switching cell QC, respectively.
