Patent GB-467998-A (GB)
Title: Process for the manufacture of water-soluble phenolic condensation products
IPC: C14C3/20
Filed: 1935-12-28
Abstract: Water-soluble condensation products are manufactured by sulphonating a fusible resin obtainable from a phenolic substance and an organic agent known to be capable of linking aromatic nuclei, without rendering it water-soluble thereby, and then treating it with a further quantity of one of the said organic reagents until it is water-soluble.  As starting materials may be employed the products obtained by condensing phenols and their substitution products, preferably in an acid medium, with, for example, formaldehyde, acetaldehyde, chloracetone or dichlorether. The sulphonation may be effected by treating these materials with less than molecular quantities of concentrated sulphuric acid or other sulphonating agents.  The products may be employed as reserving agents in dyeing goods containing wool and cellulosic fibres with substantive dyestuffs, as agents for the aftertreatment of textile fibres and tissues, e.g. for weighting, as thickening or binding agents or as tanning agents.  In examples: (1) phenol is heated with formaldehyde in the presence of hydrochloric acid, and the product (mainly dihydroxydiphenylmethane) is heated with sulphuric acid monohydrate and then condensed with formaldehyde; (2) phenol is heated with monochloracetone and the product is heated with sulphuric acid monohydrate and then condensed with formaldehyde; (3) crude cresol is heated with formaldehyde in the presence of hydrochloric acid and the product is heated with sulphuric acid monohydrate and then condensed with acetaldehyde; (4) phenol is heated with formaldehyde in the presence of caustic soda and the resin is precipitated with hydrochloric acid, heated with sulphuric acid and then condensed with formaldehyde.

Abstract: 931,153. Quenching-apparatus. W. CULL, and RZEPPA Ltd. Nov. 11, 1959 [Nov. 12, 1958], No. 36293/58. Class 72. Apparatus for quenching parts having reentrant surfaces comprises a quench tank, means to maintain the quench liquid at a predetermined temperature, means to immerse the parts into the liquid, and means to direct a flow of liquid on to the re-entrant surface area as the part enters the liquid and while subsequently immersed therein. As shown, an article 24 to be quenched is held in place by clamp 43 under hood 44. The downward movement of ram 36 lowers head 18 and all the components connected therewith including connecting jaw 37 which contacts carriage 20 by means of tongue 39. Carriage 20 runs on rails 23 and supports article 24. There is a simultaneous downward movement of piston 15 into oil-filled cylinder 10 causing oil first to flow out of radial ports 19 and then, when these ports are covered by the piston, causing a high pressure flow of oil up hollow piston-rod 16, through fluid line 49 to ports 50 and 52 and along pipe-line 53 from which it issues to impinge under pressure on the underside of article 24 as the latter descends into the oil contained in tank 1. When piston 15 reaches the end of its stroke, spherical surface 17 thereof seats on surface 14, and a flow of oil to the underside of article 24 is still maintained, though at much reduced pressure, from pump 3 through pipe 6, rail 5, non-return valve 13, and pipe 12 to hollow piston-rod 16. Oil is withdrawn from tank 1 via rail 8 and passed through heat exchanger 4 before being returned to the tank through the nozzles 7 of pressure rail 5. After a predetermined time, the rotation of all the submerged carriages 20 by motor 30 brings another carriage into engagement with connecting jaw 37. It is then raised, the quenched article 24 removed, a fresh one put in its place, and the cycle of operations repeated.

Abstract: 522,537. Machinery guards. HIRCOCK, J. W. Dec. 14, 1938, Nos. 36420/38 and 1715/39. [Class 80 (iv)] Relates to guards for thread or the like stitching, stringing and looping machines and more particularly to machines, adapted to apply string or thread handles to carrier bags, such as that described in Specification 333,253, [Class 112]. A plate 1 generally of rectangular form, viewed from the front of the machine, is hinged at 3 to blocks 2 through which needles indicated at 4 reciprocate. The guard is open at the rear and has side plates 5 adapted to enclose the needles when in the elevated position. A second plate 6, of less width than the guard and integral therewith, extends in front of that part of the machine where a loop is formed. At the side of the part 6 is another plate 7 which overlies the looping mechanism and is fixed to the machine frame, the lower edge 8 of this fixed plate abutting the guard 1 when the latter is swung into operative position. A further plate 10 carried upon a transverse strip 11a lies above the top of the guard a sufficient distance to permit a bag to be passed into the gap and covers the knotting needle. A side plate 5 of the guard has a pin 12 adapted to be engaged by a latch 13 pivoted to the machine at 14 and connected at 15 to a link 16 which, at its lower end, is pivoted to a bell-crank lever 18 an arm 19 of which is adapted to be brought into a position to prevent actuation of a pedal so controlling the operation of the machine. The arrangement is such that when the guard is up and latched, the machine may be operated, but when the guard is down a shoulder 21 on the arm 19 obstructs the pedal. The link 16 is urged upwardly by a spring 22, and when the guard is in its service position a locking arm 23 pivoted at 24 is rotated by a handle 27 to press down the latch 13 over the pin 12 and consequently move the shoulder 21 out of the path of the pedal. On the opposite side-plate 55 of the guard is a pin 28 adapted, when the guard is in the latched condition, to engage a recess 29 in a latch plate 30 fixed to the underside of a spring finger 31 attached to an angle plate 32.

Title: Improvements in and relating to the treatment of solid free flowing, pulverulent materials
Inventor: KRUSE NORMAN FREDERICK
IPC: A23L5/20
Filed: 1959-10-27
Abstract: 907,265. Removing solvent from solventextracted meal. CENTRAL SOYA CO. Inc. Oct. 27, 1959, No. 36483/59. Class 58. In treating solid, pulverulent, free-flowing material, e.g. to remove residual solvent such as hexane from solvent-extracted meal such as soybean flakes, the material is fed into a kettle A through an inlet 12 in its vapour dome 11 and then moves downwardly and continuously through kettles B, C, D and E. A casing 10, which may be heated by steam tubes or a steam jacket, constitutes the dome 11 and encloses the kettles. The kettles have hollow floors 25, 27, 29, 32 and 34, which are heated by admitting steam into their cavities. The material passes from kettle A into kettle B through an annular space between the casing and the floor 25, leaving a space 25a under the latter, and passes from kettle B into kettle C through a central opening in the floor 27. Steam is passed upwardly through the material in the kettle C from perforations in the upper surface of its hollow floor 29, which constitutes a sparging plate. The steam, e.g. containing solvent vapour, passes from the inclined face 64, of this material, through an annular space 63 and openings between louvres 60, into and through the material in kettles B and A. The steam, e.g. containing solvent vapour, passes from the material in kettle A through the dome 11, a scrubber 15 and a pipe 16 into a condenser (not shown). The material passes from kettle C into kettle D through an annular space between the casing and the floor 29, leaving a space 28a under the latter, and then passes successively into the three kettles E, through downwardly widening passages 35 in the floors 32 and 34, and is discharged from the lowermost kettle E through a gate-valve 38 and a helical conveyer 59. Apertures 45 covered by screens are provided in the floors 32 and 34 to allow upward passage of vapour from the material. A vertical shaft 19 carrying horizontal sweeping arms 40, 41, 43 and 44 is provided within the casing and is rotated, through reduction gear 22, by a motor 23. A flat member 49 riding on the material in the kettle A actuates a crank 50 turning a shaft 51 passing through a sealed bearing in the casing. A crank 53, on the outer end of the shaft, is connected to a tie rod 54, which engages a lever 55 controlling a variablespeed drive or motor 56 driving the conveyer 59. When the material in kettle A drops below or rises above a desired level, discharge from the lowest kettle E is reduced or speeded up to restore the desired level. Specification 720,184 is referred to.

The valve has inlets 32a, 32b at substantially the same level, soft ice cream from the freezer 16 being supplied to the inlet 32a through distributor chamber 33, and flavouring syrup to the inlet 32b by gas pressure in the tank (T). The valve member 40 has three O-ring seals 51, 52, 53 of which the seal 53 is canted as shown so that in the lower or closed position of the valve member it separates the inlets 32a, 32b. In the upper or open position all the O- rings are above both inlets so that ice-cream and flavouring syrup are supplied to a mixing chamber wherein a beater 44 is rotated by the shaft 34 consequent upon closure of the switch 46 by the lever 45, and thence to outlet 31. The syrup flow may be adjusted by adjustment of a regulator (62) for the gas pressure in tank (T). The tank (26) has electrical probes (121-123, Fig. 2 not shown) to provide a signal of deflection thereof and thereafter to shut down the apparatus. As described the freezer is duplicated, and each freezer is associated with two valves and outlets to provide for four flavours. In the freezer 16 there is a scraper 19a and optionally a helical stirrer 19b. The shaft 104 is axially slidable; in the position shown liquid can pass through the passage 100 and along the shaft to provide visual indication that the chamber is initially filled with liquid to the desired level. In the operative position of the shaft the passage 100 is sealed by O-rings 108, 109. The shaft 104 carries arms 106 which sense the viscosity of the material and can be arranged to shut down the motor (16m) of the freezer refrigeration unit.

Abstract: 1341936 Drum brakes TOKYO BUHIN KOGYO CO Ltd 7 Aug 1972 [7 Aug 1971] 36709/72 Heading F2E A drum brake has shoes 3 spread apart by axially movable nuts 6a, 6b screw threaded internally to receive a rod 5 having opposite handed threads 5a, 5b at each end, the rod 5 being rotated to actuate the brake through a transverse arm 7 which pivots when a link member 9 is axially moved by a fluid pressure actuator, and a slack adjusting mechanism M is provided between one side of the rod 5 and a shoe 3 to take up lining 4 wear. The mechanism M comprises a one way clutch having two elements 11, 15 provided with saw teeth, the two elements being engaged under the bias of a spring 12 abutting a stub shaft 11a of element 11 and a lost motion connection is provided between the rod 5 and shaft 11a comprising an enlargement 10a of a bore 10 in rod 5 and a key 14 pinned at 14a to the shaft 11a. If linings 4 are worn rotation of rod 5 causes rotation of element 11 after the lost motion is taken up but this rotation is not taken up by element 15 due to the shape of the sawteeth 16. When the brake is released rod 5 is rotated in the opposite direction retracting nuts 6a, 6b and rotating, through the sawteeth 16, element 15. Rotation of element 15 causes a push rod 17, externally threaded thereto, to move outwardly to take up the wear. A manual adjuster is provided comprising a gear 22 which when rotated causes pins 21, the heads of which are located in conical recesses 23 in gear 22, to move leftwardly pushing element 11 to disengage the clutch and rotate element 15 thereby extending or retracting push rod 17. In the above arrangement slack adjustment is effected during movement in either direction of drum but in a further embodiment, Fig. 5, not shown, adjustment is effected only in the reverse direction to the arrow shown in Fig. 1. In this arrangement during actuating shoulder Tb of nut 6b abuts screw housing 2 and rods (33) passing through the nuts 6b and engaging at their ends the housing 2 and secondary clutch element (35) retain the latter against leftward movement while nut 6b and clutch element 11 are moved under the brake reaction force transmitted from the brake web 19b to disengage the clutch and prevent adjustment. The brake may be of the leading shoe, trailing shoe, two leading shoe type or duo-servo type.
