Abstract: 480,389. Shock-absorbers; stamping- presses. CARTER SHOCK ABSORBER CO., Ltd., and CARTER, A. Nov. 28, 1936, No. 32628. [Class 108 (iii)] [Also in Group XXII] Relates to a cushioning or pressure-controlling appliance. for use, for example, in connection with metal-working presses for drawing, cupping, pressing, or blanking sheet-metal articles, to yieldingly support a lower tool or work-support against an elastic or yielding resistance, the appliance being of the kind n which a plunger 2 or the like working in a cylinder or chamber 28 moves under the applied force against the resistance and is returned when the force is relieved. According to the invention the upper end of the cylinder 28 is connected to an external fluid reservoir 33 through a conduit 32 provided with a pressure-controlling device adapted to be byepassed by a one-way valve 19 so that during downward movement of the plunger 2, which is cushioned by displacing air through a pipe 28a into a separate container, oil or other fluid flows freely from the reservoir 33 past the valve 19 into the upper end of the cylinder while during upward movement of the plunger, due to expansion of the compressed air, the valve 19 closes and the fluid is forced to return to the reservoir past the controlling device. As shown, the reservoir 33 is connected by the conduit 32,.with an auxiliary cylinder 29 mounted above the cylinder 28 and containing a piston 31 mounted on a stem 27 connecting the plunger 2 and platen 1. The controlling device comprises a rotary regulating valve 20 which may be operated manually or automatically from the press by means of links, rods, &c., or by the cam mechanism shown in Fig. 6 comprising a vertically-'sliding rod 34 spring-pressed upwardly and carrying at its upper end a roller 36 engaging a cam 37 on a shaft 38 driven from the crank-shaft of the press, a pin on the rod engaging the arm 22 of the regulating valve. As the depressed portion of the cam comes opposite the roller, the spring 35 operates to close or partially close the valve. The stem 27 passes, at the upper end of the cylinder 29, through a gland comprising two packing-rings 39, 40 spaced apart on either side of an annular groove 41 by a spring 42, the groove being in communication with a pipe 43 which connects with a pipe 44 in communication with the lower end of the cylinder 29 and then passes to a pump arranged below the cylinder 28. The pump comprises a cylinder 45 communicating through a one-way valve 50 and pipe. 51 with the reservoir 33 and containing a piston 46 carried by a rod 47 connected to the lower end of the stem 27. Any oil leaking past the packing-ring 40 or piston 2 is thus drawn into the pump cylinder and then returned to the reservoir.

Transmission holograms are produced by simultaneously exposing a light-sensitive layer to a coherent reference beam and a coherent beam of radiation reflected from a subject, and then photographically processing the layer to produce a coloured holographic pattern. The colour may be imparted by at least one dyestuff which preferably has a different refractive index from the binder of the layer in which it is present. If desired the background to the holographic pattern may also be coloured preferably with at least one dyestuff having a similar absorption curve to the dyestuff(s) used to colour the holographic pattern. The layer may be bathed in the dyestuff either before or after exposure. The coloured background is formed by making the reference beam have greater intensity than the reflected subject beam. The lightsensitive layer may comprise two or more different light-sensitive silver halide emulstion layers each sensitized to a different region of the visible spectrum. Examples are given of producing a negative cyan coloured hologram, a negative magenta coloured hologram, and a positive magenta coloured hologram. The holograms can be reconstructed using white light.
