Title: Coatings on surfaces of process equipment
IPC: B02C13/282
Filed: 1969-05-28
Abstract: 1,246,363. Coated articles; tube mills; impact pulverizers. ALPINE A.G. 28 May, 1969, No. 27102/69. Headings B2A and B2E. A surface of an item of process equipment which is to be in contact with gas-borne powders, e.g. a mill, classifier, sifting rotor, cyclone or pipe has a coating of soft, elastic material having hardness 10-50 shore, the thickness of the coating being such that in use the surface of the coating continuously changes its shape under the impact of gasborne powders and thereby prevents the formation of appreciable deposits of the powders upon the coating. The coating may be a solid rubber, or a foamed rubber, applied by glueing on strips or in the case of pipes by inserting and pasting together tubular parts. The coating may be composed of two layers, ie. a thick soft layer, e.g. rubber foam. As shown in Fig. 1, in an impact mill the baffle ribbed grinding track, inlet 5, outlet 6 and inner wall 4 of the housing are protected by soft, elastic coating 7. The baffle ribbed grinding track is made of rubber and is fitted with baffle ribs glued on and pasted to the inner wall of the mill (Fig. 1, not shown). As shown in Fig. 3, in a classifying mill the inlet 5, inner wall of the mill housing 4 and the classifier housing 8, sifting channels 9 of the classifying rotor 10, fines channel 11 and channel 12 for the oversize material returning from classifier housing 8 into mill housing 4 are covered with rubber foam coating 7, and the baffle ribbed grinding track 1 is made of rubber.

Patent GB-1075392-A (GB)
Title: Improvements in or relating to methods of and devices for shaping an assembly of layers of material
IPC: B27D1/08
Filed: 1964-07-01
Abstract: 1,075,392. Laminating. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. July 1, 1964 [July 4, 1963], No. 27180/64. Headings B5L and B5N. In a method of shaping an assembly of stacked layers of material, e.g. veneers, provided with adhesive, the layers are bent towards two shaping elements by means of pressure elements and clamped between the shaping and pressure elements, one clamped portion being then moved with respect to the other so as to reduce the radius of curvature of the curved portion of the assembly at the corner thereof to substantially zero by decreasing the space between the shaping and pressure elements in which the corner is confined. The shaping elements may be two surfaces of a former, one surface being provided with a resilient element, displaceable in a direction at right angles towards this surface so as to allow for the relative movement of one clamped portion of the assembly with respect to the other. As shown in Fig. 3 an assembly of layers of wood veneer 16 is clamped against a former 9 by pressure elements 17 and bent therearound by a nylon band 20 pulled tight around the outer layer. Pressure elements 18 and 19 then move in to clamp the assembly against rigid plates 13 of, e.g. hardboard attached to rubber blocks 12 located in slots in the sides 10 and 11 of the former. By exerting further pressure the plates are pushed in against the resilience of the rubber blocks until they abut stops 15 when their surfaces are coplanar with the surfaces of the side walls 10 and 11. This further movement causes the radius of curvature of the assembly at the corners thereof to be reduced to substantially zero as the space in which the corner is confined, defined between the pressure elements 18 and 19 and former 9, is decreased. During movement of the pressure elements 18 and 19 the band 20 is pulled so that it is just tight about the outer layer to support the assembly. The rubber blocks may be replaced by helical springs or by pneumatic or hydraulic components. In other embodiments the rubber blocks may be located on the undersurface of the former, or a number of parallel blocks on opposite sides of a former may carry facing plates having guiding pins extending into the former, the plates being displaceable against the resiliency of the blocks as far as stops formed by adjustable screw bolts carried on bars extending across the former.

Abstract: 765,461. Etectromagnetic relays. PYE, Ltd. Oct. 6, 1954 [Oct. 6, 1953], No. 27391/53. Class 38(5) Mounted between a pair of cheek plates 1 in a sealed chamber 26 are pole pieces 2, 3, ceramic supports 16, 17 each carrying a number of opposed fixed contacts 18, and a ceramic support 20 carrying a corresponding number of contact blades 19 biased towards the contacts 18 on the support 16. The armature 4 pivoted at 6 on the pole piece 2 and biased by a spring 9 against an adjustable stop 14, carries a transverse ceramic rod 23 whereby on energization of the relay to move the armature against the pole piece 3, the rod 23 moves the 'blades 19 against the contacts 18 carried by the support 17. Contact bounce is reduced since the biasing effect of the spring 9 on the armature steadily weakens as the armature moves towards the vertical. The movement of the contacts 19 is damped by spring blades 25 which press against the contact edges. The contacts 18 comprise screwed rods to permit their adjustment. The relay parts in the chamber 26 are supported by magnetic struts 27 sealed through the chamber wall and carried by a magnetic frame 28 having two energizing coils 29.

Abstract: 1,171,299. Automatic circuit - breaker. ALLEN-BRADLEY CO. 13 Sept., 1966 [20 Sept., 1965], No. 27431/69. Divided out of 1,171,297. Heading H1N. In an automatic circuit-breaker in which a yieldingly restrained contact latch release lever arm 101, Fig. 4, is engaged by a current overload device such as a spring loaded plunger 23, Fig. 3 (not shown) of a solder pot and ratchet release device, the lever arm 101 is locked against manual reset if the contact carrier 3, Fig. 8, fails to return to the "off" position shown. The arm 101 is restrained to its operative position by a spring 104 and upon overload current actuation rotates arm 103 of a trip pin 98a to release a catch lever 96 normally holding toggle mechanism 66 of the contact actuating mechanism in its lower operative position. To prevent manual reset if the contacts are still closed (contact carrier 3 not returned) a trip lock lever 110 on the same pivot 102 as that of lever 101 drops to lock the arm 103 of latch pin 98a by engaging a projection 114, Fig. 9, under a part of the arm 103 and thereby preventing its restoration to the latched position under the action of its return spring 104. The lock lever 110 is disengaged only when the contact carrier 3 moves up to its open-circuit position (Fig. 8) and rotates the lever 110 by engagement with a depending finger 115 thereof. The actuator is then free to be manually reset by an extension arm 107 of the pivoted actuator 64 when the relevant pushbutton 87 is depressed. The toggle actuating mechanism 66 forms the subject of Divisional Specification 1,171,300.
