Patent GB-1151137-A (GB)
Title: Power Driven Presses.
Inventor: JEAVONS DANIEL
IPC: F16P7/02
Filed: 1966-12-06
Abstract: 1,151,137. Machinery safety devices; external shoe drum brakes; automatic brakes. TAYLOR & CHALLEN Ltd. 30 Nov., 1967 [6 Dec., 1966 (3)], Nos. 54505/66, 54506/66 and 54507/66. Headings F2E, F2F and F2J. In a crank-shaft-driven power press having its stroke adjustable by a double eccentric (5, 6) (Fig. 1, not shown), the crankshaft is braked if the press overruns or reverse-runs when its guard is open, the brake being actuated by a cam 35 synchronized to rotate with the crank-shaft but phase-adjustable relative thereto to correct the cam timing after alteration in the press stroke, the double eccentric causing a phase alteration between the crank-shaft and the tool. The brake comprises external shoes 17 pivoted together at 18 and embracing a brake drum 16 on a shaft (13) geared to the crank-shaft. One shoe has a fixed pivot and the other is pivoted to a toggle linkage 20, 21, the lever 21 having a fixed pivot 22. For normal braking, compressed air is admitted to a cylinder 23, the piston of which acts on the lever 21 to straighten the toggle. When the brake wear reaches a predetermined amount, the lever 21 closes a micro-switch 49 on brake application to energize a warning lamp indicating the need for brake adjustment using the turnbuckle 19. A follower 34 for the cam 35 is formed on a plate 30 pivotable about a substantially horizontal axis on a pin 31 which is in turn pivotally mounted on the lever 21. The plate 30 is connected to the press guard (not shown) by a rod 28, a lever 26, and a rod 25, so that when the guard is closed, the follower 34 is held clear of the cam, but when the guard is open, the follower is in the path of the cam. If the crankshaft over-runs top dead centre (T.D.C.) position when the guard is open, the nose 37 of cam 35 strikes the follower 34 to pivot it anti-clockwise until a pin 38 on the plate 30 engages a shoulder 39 on the lever 21 and the brake is applied by the inertia of the rotating parts. At the same time the follower 34 actuates a micro-switch 40 to cut off the current supply to an electric motor (11) driving the crank-shaft. If the crank-shaft reverses at T.D.C. a notch 45 in the cam 35 engages a pawl 43 pivoted to the lever 21 to apply the brake. The cam 35 is mounted on the crank-shaft, a key 41 engageable with notches 42 allowing the phase-adjustment. After overrun braking, the brake is jammed on, and the crank-shaft must be forced back past T.D.C. by the motor. To allow this, which would normally be prevented by the pawl 43, compressed air is admitted to a cylinder 46 to pivot the pawl 43 clear of the cam and to actuate a micro-switch 48 which changes over the motor connections ready for reverse running.

Abstract: 1527227 Copying by scanning CROSFIELD ELECTRONICS Ltd 12 Dec 1975 [18 Dec 1974] 54670/74 Heading H4F A method of reproducing coloured originals comprises scanning the original to produce colour signals, producing colour-component signals representing the effect of scanning a set of standard colour patches passing both signals through an adjustment unit to a display whereby the operator can correct the reproduced colour using the adjustment unit, sampling the adjusted colour patch signals and applying the sampled signals to a modifying means which then applies a colour correction to the signals from the original so that a reproduced print generated under control of the modifying means has the same colour as shown on the display. In one embodiment, Fig. 3, colour patches 48 mounted with the original 49 on a rotating drum are scanned and the signals collected in store 64 for readout and display on monitor 70 so that an operator can control display adjustment unit 68 to correct the colour. A sampling circuit 72 controlled by colour computation unit 56 (modifying means) samples the displayed colour patch signals and passes them to the unit 56 which then applies a correction to the original scanning signals. In a further embodiment (Figs. 1 and 2, not shown) a separate picture (8) and set of colour patches (9) are scanned by a TV camera and passed through an adjustment unit to a C.R.T. display. The adjusted colour patch signals are sampled and stored on tape for subsequent use as comparison signals in a set up period of the main analysing system (Fig. 2) wherein further colour patches are mounted with the original to be reproduced on a drum (50). Alternatively signals equivalent to adjusted colour patch signals may be generated electronically.

Abstract: 1,214,345. Cooling granular material. SNIA VISCOSA SOC. NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA. 19 Nov., 1968 [22 Nov., 1967], No. 54806/68. Heading F4U. Granular material of low thermal conductivity which is conveyed in a pneumatic circuit is cooled by the interposition of a rotary cooling drum in the circuit. As illustrated, the drum 10 has internal lifter blades 14, is arranged with its axis inclined to the horizontal, and is connected by an inlet 33 and outlet 34 into the pneumatic circuit. A conical baffle 40 aids the distribution of the incoming material over the surface of the drum. Due to the large diameter of the drum compared with that of the pneumatic circuit pipes, material is moved along the drum solely by the action of gravity and the lifter blades rather than by the gas stream. The drum is made of metal and is externally cooled by water which is sprayed from a pipe 23. The granular material may be a polyamide material which is to be cooled in a nitrogen atmosphere after drying.
