Title: Safety gate for press
IPC: F16P3/04
Filed: 1970-03-13
Abstract: 1310181 Machinery guards M KOMORI 13 March 1970 [24 March 1969 10 Sept 1969] 12254/70 Heading F2J  Safety apparatus for a press comprises a guard G supported by a parallel lift assembly of interconnected links 28, 29, 31, 32, 34, 36 and 37, springs 25, 39 which, on release of a latch L, urge the assembly into a guarding position, and a link 27 connected to link 28 and adapted to be moved to the left in order to move the guard to its non-guarding position. A crank member 24 is pivotally mounted on a pivot pin 26 and has one arm attached to the link 27 and the other arm 23 engaged by a lever 20 which is pivotally mounted on an axle 19. One end of the lever 20 is adapted to be engaged by latch L, which is controlled by a solenoid 8, and the other end of the lever 20 is adapted to engage a pivotally mounted hook 21 carried by a pivotally mounted plate 10 to which is connected a cable 13 connected to the operating clutch of a worm W which effects movement of the press ram. On actuation of a switch H, solenoid 8 releases lever 20, thereby causing the guard G to be moved to its guarding position, and simultaneously the ram clutch is actuated. When the ram ascends, the cable 13 rises and causes the hook 21 to rotate the lever 20 clockwise, thereby causing descent of the guard G and re-engagement of the lever 20 by the latch L. If it is required to move the guard downwardly into a guarding position, link 27 is connected to crank member 24 in the manner shown in Fig. 8. The latch mechanism L may be replaced by a pump 41 and piston 42, the link 27 being coupled to the piston 42, as shown in Fig. 9. In another modification, the gate is operated electrically by solenoids 48, 49, and a pantograph-type linkage is employed, Fig. 10. The solenoids may be replaced by a latch mechanism similar to that shown in Fig. 1. In a modification shown in Fig. 17, a guard G is carried by parallel bars 106a, 106b and is moved to its guarding position by a pneumatic motor 109. A spring assists the return of the guard to its former position. A lever 115 operates a switch 119 controlling movement of the ram. Micro-switches may be associated with a drive shaft so that should the ram accidentally begin to fall, the gate will be raised immediately. In a further modification, a parallel bar type gate is controlled by a solenoid operated latch. Fig. 23 shows an embodiment in which a reversible motor 140 drives a rotary arm 142 coupled to a pivot block 105b.

Title: Improvements in or relating to braking mechanism
IPC: F16D65/54
Filed: 1936-04-30
Abstract: 472,666. Brakes; linkwork. ASSOCIATED EQUIPMENT CO., Ltd., and TRENCH, J. T. April 30, 1936, No. 12344. [Class 103 (i)] [Also in Group XXIV] The hand lever 14 and shaft 12 are connected by ratchet mechanism 15, 17, the angular setting being adjustable by a telescopic control rod 21, 22. The rod is secured at 20 to a toothed section 15 splined on the cross-shaft 12 and the pawl is pressed into the sector sufficiently strongly to ensure that the lever 14, sector, and shaft move as one during ordinary manipulation. An arm 19 connected to the brakes is also splined on the shaft. The rod 21 has ratchet teeth 26, and an inter-engaging spring-pressed key 27 is contained in a casing 29 on the tube 26, which is slotted at 24 to engage a pin 25 on the frame 10. As the linings wear and the " on " position of the lever moves to the right there comes a time when the end 24a of the slot strikes the pin, with the result that the rod is shortened. The shaft 12 is therefore prevented from returning to its former setting, whereas the lever 14 does so. Specifications 359,068 and 382,125 are referred to.

Filed: 1966-03-23
Abstract: 1,145,355. Inverting. LICENTIA PATENTVERWALTUNGS G.m.b.H. 23 March, 1966 [24 March, 1965], No. 12788/66. Heading H2F. In an inverter circuit of the type in which a resonant circuit is maintained in oscillation by triggering a bridge of thyratrons, the disadvantages due to imprecise determination of the voltages across the thyratrons are avoided by centre tapping the capacitor, and connecting it to the centre tap of the power supply. The whole capacitance may be formed by two series connected capacitors (2, 2<SP>1</SP>), the junction of which is connected to the junction of two power sources, Fig. 2 (not shown). Alternatively, the two series connected capacitors (2, 2<SP>1</SP>) may be in shunt with a main capacitor (211) and the tap on the power supply may be provided by two series connected resistors (8, 8<SP>1</SP>) across it, Fig. 3 (not shown). The inductance (4) of the resonant circuit may include a saturable choke (3) in series with it, to disconnect it when the thyratrons are charging the capacitance. Alternatively, the choke may be replaced by a further thyratron.

Abstract: 511,998. Gravity-separation apparatus. WOOD, C. E. April 29, 1938, No. 12856. Convention date, May 19, 1937. [Class 46] Liquid-borne material is delivered with a vertical motion to a classifier settling-bowl 6 and the settled matter is pushed by blades 46, moving at the same rate as the surrounding liquid, into a hopper 15, which is mounted so that it rises or falls in accordance with the weight of its contents, its movement automatically controlling a valve 30 so that solid matter is discharged from the hopper at the same rate as it is received in the bowl. As shown the material is supplied tangentially by a flume 33 to a chamber 34 and passes through a rotating fan 36 with radial baffles into the bowl 6, where it is distributed, still retaining its vertical motion, by a baffle 41. The settled matter is pushed to an outlet 10 by helical blades 46 on arms 45 supported from a shaft 39 rotated by means of a motor 43. The hopper 15 is supported by a sub - frame 16 suspended by links 17 from counterbalanced scale beams 18. A diaphragm 20 connects the rim of the hopper to the bottom of the bowl. The valve 30 is mounted on a lever 25 connected to the scale beams 18 by a link 24 so that a relatively slight movement of the hopper causes a rapid opening or closing movement of the valve.

The process may be used in the "Duo Sol" solvent extraction process wherein 2 immiscible solvents are flowing countercurrently.  Liquid mixtures specified are petroleum fractions such as gasolines, naphthas, kerosenes, gas oils, e.g. catalytic cycle gas oil, and lubricating oils.  Solvents referred to are nitrobenzene, liquid propane or sulphur dioxide, b ,b 1-dichloroethyl ether, phenols, furfural and liquid hydrogen fluoride.  The process is described with reference to the Figure which shows an extraction zone, consisting of a contacting zone superimposed on a settling zone, containing contact masses to promote mixing.
