Title: Improvements in and relating to Butterfly Valves.
IPC: F16K1/22
Filed: 1967-06-07
Abstract: 1,193,190. Valves. MAENAKA VALVE WORKS CO. Ltd. 7 June, 1967 [8 June, 1966; 13 June, 1966; 29 Aug., 1966], No. 26261/67. Heading F2V. The closure member 36 of a butterfly valve 35 is rotatable between its open and closed positions by means of a rod 37, the rod being coupled to an actuator 27 having two opposed non- linear cam grooves engageable by a pin 28 extending from one end of, and transversely to, an acutator stem 25 which is movable vertically, but non-rotatably. The stem movement is effected by the application of fluid pressure to one of two ports 22 disposed one at each end of a casing 21 within which a piston 24, secured to the other end of the stem 25, is movable, or, alternatively, by a screw and handle mechanism, (Fig. 6, not shown). Vertical movement of the piston 24, and hence stem 25 results in rotational movement of the actuator 27 and consequential opening or closing of the valve. The rod 37 is made of precipitation hardened stainless steel.

Title: Electrosensitive recording medium having a plurality of recording layers
IPC: B41M5/24
Filed: 1972-06-06
Abstract: 1371683 Electrosensitive recording sheet H MATSUSHIMA 6 June 1972 [13 June 1971 4 Aug 1971 7 Dec 1971] 26387/72 Heading D2B [Also in Division Gl] An electro sensitive recording medium of the type comprising laminated recording layers, recording being achieved by local destruction of a layer or layers by electric discharge, comprises a base layer B carrying on at least one surface at least two superimposed recording layers R 1 , R 2 , .. each recording layer comprising a coloured layer C 1 , C 2 , .. of high electrical resistance and different in colour for each recording layer, and a thin electro-conducting layer E 1 , E 2 , . . so that multi-colour recordings can be made. The base B may be of paper or a plastics film such as acetate, vinyl chloride, polyethylene, polyester, or a paper/plastics laminate. The coloured layers C may be a mixture of pigment and zinc oxide or titanium oxide, or high resistance printing inks, may be opaque or transparent, and have a thickness of 5-10 microns. The electroconductive layers E are of metal, e.g. aluminium, zinc, nickel, antimony, selenium, tin, plated or vacuum-deposited to a thickness of up to 1 micron. In Fig. 3A a surface contact electrode A and a recording electrode D lightly contact the top conducting layer E 2 . Application of a first voltage, e.g. 50 volts, destroys a small area of layer E 2  adjacent the electrode D so that a spot of colour C 2  becomes visible. A higher voltage, e.g. 100 volts, would destroy layers E 2 , C 2 , E 1  so that a spot of colour C 1  becomes visible. With further recording layers, further voltage steps are used. In Fig. 6A a separate surface electrode A is provided for each recording layer, these being selectively energised so that all layers are destroyed under the recording electrode D down to and including the energised layer E. In Fig. 9A the conducting layers E are electrically interconnected at their edges G, a single surface contact electrode A being selectively energised to different voltage levels as in the Fig. 3A embodiment. The recording surface (Figs. 4A, 7A, 10A, not shown) or the whole surface (Figs. 5A, 8A, 11A, not shown) of the recording medium may have a 10 micron protective coating (F) consisting mainly of zinc oxide or titanium oxide. Colours other than those of the layers C can be obtained by producing alternate spots of two or more of the available colours.

Abstract: 882,960. Inking-apparatus. DE LA RUE & CO. Ltd., THOMAS. Feb. 1, 1960 [July 31, 1959], No. 26439/59. Class 100(2) An inking mechanism for a printing machine comprises a transfer roller adapted intermittently to coact with a printing plate and to be frictionally driven by an ink distribution roller across the periphery of which said transfer roller oscillates in an arcuate manner and in continuous contact therewith. The distribution roller 10 on a shaft 12 is driven by gears 5, 14, 13 at the same peripheral speed as the plate cylinder I. The transfer roller 11 is mounted on a shaft 16 held in a split bearing 38 on a carriage 37 slidable on a member 35 pivoted on the shaft 12. The position of the carriage is adjustable by a handle 41. The roller 11 is oscillated about the shaft 12 by toggle mechanism 25, 26, 28 actuated by a link 24 under control of a cam 6 on the gear 5 and a spring 23. The pressure of the roller 11 on the cylinder 1 is adjusted by an eccentric spindle 29.

Title: Improvements relating to clamps for slicing machines
IPC: B26D7/02
Filed: 1928-09-15
Abstract: 322,818. Fitzpatrick, H. D., (Maatschappij tot Vervaardiging van Snijmachines Volgens van Berkel's Patent en van Andere Werktuigen). Sept. 15, 1928. Cutting slices in succession.-The deposition of grease and dirt on the bearing surfaces of the clamp posts is prevented by shielding the bearing surfaces. As shown in Fig. 2, the post 2 is made in tube form and the clamp bar 4 is pivoted to a block 5 slidable inside the post which is slotted at 15 to permit the vertical movement of the bolt 9. The block 5 is recessed at 17 to receive a shoe 18 pressed downwardly by a spring 19 and urged outwardly by a roller 20 engaging with inclined surfaces 17a, 20<a>. The upward pressure of the meat on the bar 4 tends to raise the block 5 and jams the shoe 18 against the tube post 2, thereby locking the clamp. A handle 7 is pivoted to the block 5 at 21 and, when it is lifted, releases the shoe 18 by raising it, this being effected by a member 22 embracing the handle and secured by screws 23 to the shoe. When the handle 7 is swung down, a stop 24 contacts with the block 5. Pressure on the handle depresses the block 5 and frees the shoe 18. When two guide posts are used, they are both arranged to receive blocks 5, the bar 4 being pivoted directly on one block 5 and on a bracket extending along the side of the meat table and carried by the other block 5. Each post has a removable cap on its top. The handle 7 on one block 5 may be dispensed with, the bar 4 contacting with a bracket on the shoe 18 and lifting it when the clamp bar is raised. In the modification shown in Fig. 5, the clamp is arranged as described in Specification 20989/13 and the surfaces of the solid posts 41, 42 are protected by semicylindrical shields 48 held at the top and bottom end of the posts by screws 49 and pins 50 passing through the posts. If desired, the shields 48 may be cylindrical and slotted for the passage of the parts projecting from the sleeves 43, 44. The handle 45 may be dispensed with and adjustments effected by the handle 46 alone, e.g., as described in Specification 261,396. In Fig. 7, the clamp is locked by means described in Specification 253,546, and each of the posts 58, 54 is provided with a shield 57 secured to the tops and bottoms of the posts. The shields pass through openings 58 in the clamping bar. The invention may be applied to single post clamps, or to a machine wherein the substance is slid over a fixed table, the clamp also moving with the substance.

[Class 37] The rotor of an induction meter consists of a number of layers of conductive material insulated from each other, and divided intc sectors which are over lapped so that the eddy currents due to one field or brake magnet system do not interact with those due to an other field or brake magnet system. The disc layers 17 ... 21 are slit at 23 and are separated by insulation 22, the whole assemblage being put under mechanical pressure to squeeze out any superfluous insulation, for example, shellac, and they are then riveted together by the parts 24, 25.
