Title: Improvements in inks, water colour paints and like compositions
IPC: C09D11/00
Filed: 1921-07-30
Abstract: Colloidal solutions of lakes are produced by subjecting an insoluble base to highspeed intensive mechanical disintegration p  with water to form a colloidal solution, to which is added, during disintegration or not, a relatively small quantity of organic dye. The base used may be clay or zirconia, which being opaque and in colloid form, absorbs the dye to form a product of high colouring power.  The base is treated with water in a colloid mill such as described in Specification 155,836 and then, after settling, is again treated in the mill with a soluble organic dye in the presence of a protective colloid, for example, gum arabic, to counteract the precipitating action of electrolytes in the water, and, if copying ink is being prepared, glycol, glycerine or the like may be added.  A small quantity of disinfectant may be added to prevent decomposition of the protective colloids.  Instead of a colourless base, coloured insoluble substances such as ultramarine or lakes may be used in the colloidal state with a correspondingly less amount of dye.  For Indian ink or water-colour paints, colloids such as cherry-tree gum may be added, and colloidal clay or colloidal carbon used as the mineral base.  If tannate or gallate of iron is used as the soluble ink base, an aniline dye is added to give the desired colour until the iron salt is oxidized.ALSO:In a process for making ink, water-colour paints, and like compositions, an insoluble base is subjected to high-speed intensive mechanical disintegration with water to form a colloidal solution, to which is added, during disintegration or not, a relatively small quantity of organic dye.

Title: Quick make-and-break ceiling switch
IPC: H01H17/00
Filed: 1933-07-20
Abstract: 409,536. Snap-action switches. COOK, F. L., 42, Mollison Street, Abbotsford, Victoria, Australia. July 20, 1933, No. 20539. Convention date, Aug. 16, 1932. [Class 38 (v).] A quick - action ceiling switch comprises a U-shaped contact-member 2 which has depending arms 11 fulcrummed in V-shaped recesses in the body of the switch and is connected by a tension spring 3 to a floating intermediate member 1 which is connected by a pin 8 to a flexible pull 6. When the cord 6 is pulled the member 1 moves bodily against the action of the spring 3 until an arm 13 engages an abutment 14 to tilt the member 1 and carry the lower end of the spring 3 across the dead centre causing the contact member 2 to snap over. On release of the cord 6 the spring 3 draws up the member 1, the pin 8 resting finally in a recess 17 opposite to the recess in which it originally rested. The member 1 is then in such a position that on pulling the cord 6 the other arm 13 will engage the other abutment 14 and the action is reversed. Upper arms 23 on the member 1 engage the spring 3 to give a positive start to the contactmember. The body of the switch thus carries all the mechanism except the fixed contacts and can be removed as a unit after removal of the cover by simply pulling the body away from the base.

Filed: 1954-07-16
Abstract: 787,182. Magnetic amplifiers. SMITH & SONS (ENGLAND), Ltd., S. July 14, 1955 [July 16, 1954], No. 20854/54. Class 40 (4). An auto-self-excited parallel transductor having transductor elements 8 and 12 and rectifiers 9 and 13 controls the power delivered by an A.C. source 1 to a load 2 by means of the application of an A.C. signal of the same frequency as the A.C. source to terminals 3 and 4. The A.C. source 1 supplies a centre-tapped transformer 6 which takes the cores of transductor elements 8 and 12 to saturation alternately, the load being energized by centretapped transformer 10. When rectifier 9 conducts during a half-cycle in which the A.C. source and A.C. signal have the polarities shown, transductor element 8 is driven to saturation and rectifier 9 is biased to conduct to provide a path for control current through transductor element 12 as shown by full arrows. The magnitude of the control current is determined by the A.C. signal at terminals 3 and 4 which opposes the voltage induced in the right-hand half of the secondary of transformer 6. When polarities are reversed in the following half-cycle of the A.C. source, control current flows as shown by the dotted arrows. The control current is made to flow through transformer 10 which is such as to de-couple the signal input from the load 2.

Abstract: 1449806 Gyratory crushers PORTEC Inc 16 May 1975 [28 May 1974] 20882/75 Heading B2A A gyratory crusher has a peripheral frame 1 having an uppermost annular V-way 104 Fig. 8, a conical mantle 2 Fig. 2 in the frame, a bowl assembly 4 above the mantle 2 including a cylindrical body 22 with an outer cylindrical periphery 26 of lesser diameter than the peripheral frame, an annular support ring 31 around the bowl body 22 and vertically displaceable relative thereto. The support ring 31 has a downwardly facing annular cavity 36 mating with the frame V-way 104 and supported on it, and has an inwardly facing wedge surface 34 radially spaced from the periphery of the bowl body. A segmented bowl clamp ring 37 surrounds the bowl assembly between the outer periphery and the support ring wedge surface and has an outwardly facing wedge surface 38 adjacent the support ring wedge surface 34. Bolts 58 Fig. 1 are carried by each segment of the clamp ring 37, with stop means on the upper distal part of the bolts. The bolts 58 are surrounded by fluid actuated expansible washers 46' between the stop means and the supporting ring, so that the clamp ring segment can be urged upwardly against the support ring as the two juxtaposed wedge surfaces force the segmented clamp ring radially inwardly to clamp the bawl assembly to the support ring. To readjust the bowl elevation a single lift cylinder 29 is associated with each pair of segments of the clamp ring 37. When the cylinder 29 is pressurised a release pin 67 Fig. 9 engages a platform 68 of the ring 37 and breaks the wedging action between bowl assembly and bowl support ring 31. To relieve overload due to tramp iron shock load relief cylinders 72 and hydraulic accumulators 80 are provided to relieve displacement of the bowl support ring 31. Tapered guide pins 83 Fig. 8 are arranged around the ring 31 which do not bind with apertures in the frame 1 when the ring 31 is displaced. To prevent the head 5 spinning during no load a pump 93 Fig. 4 having a check valve 99 permits a shaft 94 to rotate in one direction for crushing. The head is inhibited from contra-rotation by the resistance of the check valve 99 to reverse rotation of the pump. The oil supply to the pump serves also for general lubrication.
