Title: Improvements in or relating to machines for cutting or slicing wheat, grain or other granular materials
IPC: B02C9/02
Filed: 1923-04-16
Abstract: 208,974. Booth, W. April 16, 1923. Apparatus. - A machine for cutting or slicing wheat, grain, or other granular materials comprises a perforated plate through which the grain passes, a radially-slotted plate spaced from and beneath the perforated plate and relatively rotatable in regard thereto, and flat cutting-blades secured flat upon the upper surface of the slotted plate with their cutting-edges overlapping the edges of the slots and travelling upon the lower surface of the perforated plate. As shown, the grain is fed from a hopper 13 into a cylindrical pan 10 and passes through perforations 12 in the bottom plate 11. A vertical shaft 4, guided by a boss 15 on the plate 11 and driven through bevel gearing from a driving-shaft 7, carries a flat circular plate 32 to which segmental cutters 30 are secured by bolts 31. The plate 32 has radial slots 33, Fig. 4, and the edges of the cutters 30 project over the sides of the slots. Both radial edges of the cutters are sharpened so that the machine can be run in either direction, and the edges of adjacent cutters are inclined so that the gaps 34 widen towards the circumference of the plate 32. Radial brushes or scrapers 22 detachably secured to arms 23 on a hub 24 on the shaft 4 work over the upper surface of the plate 11. The sliced grain &c. falls through the gaps 34 between the cutters into a hopper 25 having an outlet pipe at its lower end. Magnets 27 may be arranged in or adjacent to the feed-hopper 13 to remove any metallic particles that may be present in the grain &c. The cutters and brushes may be stationary and the perforated plate 11 rotatable. The plate 11 may be removable from the pan 10 so that plates having perforations of 'different sizes can be used.

Title: Improvements in or relating to locking means for the doors of cabinets or casings housing electrically driven machinery
Inventor: REDFEARN ROBERT NEVILLE
IPC: D06F37/42
Filed: 1968-10-31
Abstract: 1,243,376. Machinery safety devices. FISHER-BENDIX Ltd. 23 Oct., 1969 [31 Oct., 1968 (2); 26 Feb., 1969], Nos. 51696/68; 51697/68 and 10363/69. Heading F2J. [Also in Division H2] The door of an electrically driven machine, e.g. a washing machine, has a latch which is held in its door-locking state during running of the machine by a solenoid C3, and when the motor is switched off it acts temporarily as a generator to maintain energization of the solenoid until the machine speed has fallen to a predetermined safe value. The motor circuit has a field winding S4, an armature A, a forward/ reverse switch S1, a wash/spin speed selector switch S2, and a normal running/braking selector switch S3 which is actuated by a no-volt relay C2. A control unit C1 has an earth terminal T2 and a neutral terminal T1. In normal running the solenoid C3 is in parallel with the relay C2. When power is cut off, the switch S3 moves to position B and the solenoip C3 is paralleled with a braking resistor S5 across the field and armature windings of the motor. The braking resistor may be a waterheating element, as shown, energized in normal running through a timer switch 36, 37 and a water level switch 38, 39, or a separate resistor (Figs. 1, 3, 5, not shown). In Fig. 7 (not shown), the control unit (C1) contains a rectifier bridge circuit (M1) and no terminal is at earth potential. The wider speed range possible with this control permits the speed selector switch S2 to be omitted. When power is cut off the relay (C2) (not shown) also isolates the bridge circuit from the motor to protect the semi-conductors therein.

A tool-slide actuating mechanism for an automatic lathe &c. adapted to effect a rapid movement up to the work, a relatively slow feed during cutting, and a rapid return, comprises the combination of a slide-actuating rack, a pinion or quadrant in engagement with the rack, a primary lever, a secondary lever pivoted on the primary lever, adjustable means interconnecting the secondary lever and the pinion &c., a toggle mechanism for actuating the primary lever, and cams for actuating the toggle and the secondary lever. A tool-slide a, co-operating with a work-spindle o, carries a rack b engaging a quadrant c: the latter is connected through linkage d, e, by an adjustable pivot member g to the arm h of a bent lever, the other arm f of which carries a roller k engaging a cam-track m. This lever, referred to as the secondary lever, is pivoted intermediate its ends to the end of a primary lever i which at its other end is pivoted at j to a fixed bracket. On the free end of the primary lever i, on the side opposite the pivot for the secondary lever, one end of a toggle linkage p, q is pivoted. The opposite end of the toggle linkage is pivoted at a fixed point r. A roller s on the upper toggle link q engages a cam groove t cut in the face of a disc n opposite the face with the cam groove m. Fig. 1 shows the mechanism in the withdrawn position of the tool-slide a. The toggle links are first brought by the cam disc into alignment for the quick approach, the free end of the primary lever i thus being brought into engagement with a stop-member u. The relatively slow cutting movement is effected by rotation of the secondary lever f and finally both cams effect the rapid return movement. The mechanism aims at reducing the load imposed on the cams while the tool is cutting. A second tool slide may be actuated from the secondary lever h by linkage similar to that for the tool-slide a.

Title: Process for the continuous fixation of water-soluble sulphur dyes on cellulosic fibres
IPC: D06P1/22
Filed: 1976-03-17
Abstract: A web-like textile material made of cellulose fibres is dyed with water-soluble sulphur dyes by the two-bath method. The textile material is padded in succession and without drying it in-between first with a dye liquor with the addition of a partial amount of sodium sulphide and then overpadded with the hot reducing agent liquor containing sodium sulphide and sodium polysulphide, the total amount of sodium sulphide being at most 50% by weight of the known sulphide demand. This is followed by an air passage of at least 10 seconds. The textile material is then passed through an open-width washer in which the dye(s) applied by padding is or are reconverted into its or their water-soluble disulphide form by reoxidation. The additional use of sodium polysulphide as redox buffer avoids spontaneous oxidation of the leuco dye by atmospheric oxygen during the air passage, which may give rise to undesirable bronzing effects.
