Title: Mounting clips
IPC: F16B2/24
Filed: 1962-03-06
Abstract: 998,469. Clamp fastenings. G. A. TINNERMAN. March 6, 1962, No. 8600/62. Heading E2B. A mounting clip comprises two opposed spaced arms 29 formed from resilient material, the arms being adapted to be anchored each at one end and bent to form means for gripping an object, the other end portions being formed to provide upstanding shanks 32 and coupling elements 34 angularly disposed with respect to the shanks, one at least of the coupling elements being orificed and at least the other of them having an outwardly bent lug 36 upstanding from the plane thereof and so disposed as to co-operate with the orifice 35 formed in the companion coupling element, the said lug having an edge 37 that is inclined rearwardly and upwardly from the surface of the coupling element in a direction away from the free end of that element to provide at its highest point a shoulder 38 rising from the coupling element, the inclined edge forming a guide to bear against the inner face of the companion coupling element so as to guide the shoulder into the orifice of the companion element when the shanks are pressed towards one another in order to cause the coupling elements to overlap, the arms then serving to grip the object between them when the coupling elements are fastened together. As shown, each arm has a lug 36 and an orifice 35 and each arm is provided with an orifice 30 near the other end by which it can be anchored to a projection on a base to which an object is to be secured. In a second construction (not shown) the arms are formed integrally with a base, the base having an orifice made in such a manner as form a nut for a threaded stud. Alternatively it can be a simple orifice for a nail or other fastening member. Each of the arms in this construction either has a lug and an orifice as in the previous construction or alternatively only one arm has a lug although both have orifices; in this case the arm with the orifice only, is formed, with an offset tongue which helps to guide the coupling element into engagement with the lug of the other arm and also forms levering means for separating the arms when desired.

Title: Improvements in or relating to kibbling mills
IPC: B02C2/10
Filed: 1924-04-05
Abstract: 222,406. Heller, J. April 5, 1924. Conical mills.-The mill frame, or casing u of a kibbling-mill carries a vertical tubular bearing a for the shaft N of the runner w, and the hub h of the driving-pulley t mounted on the outside of the tube a carries a claw coupling p to engage claws q on the lower side of the runner w. A collar n on the shaft N rests upon the upper end of the tube a, and above the collar n the shaft N is formed as a tube n<1> into which extends the bearing spindle r of the kibbling-ring w, which is keyed to the part n<1>. A spindle z is arranged between the closing-plate 6 and the thrust-plate 7 at the lower end of the spindle r. The distributing plate b carrying the distributing cone d rests upon the plate 6 and is freely rotatable upon the spindle r, which is carried by a nut k connected by webs with the hollow hub k<1> of a hand-wheel K. By turning the wheel K, the tension of the spring z and consequently the pressure in the grinding slot may be adjusted. A hand-wheel F screws into the movable lid X and the lower end of its hub f<1> lies above the plate b so that by turning the. wheel F the aperture through which the grain passes can be regulated. A hand-wheel e screwed upon the hub f<1> forms a locking nut to retain the hub f<1> in the set position. The hub h of the pulley t rests upon a shoulder 9 on the tube a, and the lower end of the shaft N dips into an oil sump m. Oil passes through radial slots 5 in the tube a to the shaft N, and up through helical grooves in the shaft N to the collar n, whence it passes by ducts y to the outer surface of the tube a and by spiral grooves in the inner surface of the hub h to the shoulder 9, and thence by ducts O in the bottom of the mill frame back to the sump m.

Title: Improvements in and relating to electric switches
IPC: H01H1/52
Filed: 1924-04-07
Abstract: 229,136. British Thomson-Houston Co., Ltd., (General Electric Co.). April 7, 1924. High-potential switches; latching and unlatching; contacts; handles.-In a switch having a rotatable latch co-operating with a switching- member, the latch pivot is so arranged that any tendency for the switching-member to open increases the tendency of the latch to keep the switching-member closed. The switch-member or blade 1 is formed of two spaced strips embracing a hinge 2 and contact 3 and engages a a flared, bifurcated member 10 to ensure its alignment with the contact 3. An aperture 7, adapted to be engaged by the operating implement 20, is formed either in the blade 1 or in an eye-piece 8 pivoted thereto and formed with a tail which engages a projection 9 on the contact 3 to give an initial opening movement to the blade 1. The latch 12 is pivoted at 13 to a projection 14 on the member 10 and is biased to latching position by a torsion spring 15, the arrangement being such that any tendency of the blade 1 to open will increase the tendency of the latch to hold the blade closed due to the location of the pivot 13 to one side of the longitudinal axis of the blade. A stop 17 and notch 18 limit the movement of the latch. The opening movement is shown in Figs. 2 and 3, in which the inclined side 22 of the implement 20, on being inserted into the aperture 7, first moves the latch clear by sliding along the blade 1 and engaging the projection 19, and then lifts the blado so that one continuous pull on the member 20 moves the latch and also opens the switch. The side 23 is used for closing as shown in Fig. 4. The arrangement is also applicable to double-throw switches.

Title: Improvements in logarithmic calculators
IPC: G06G1/00
Filed: 1950-04-11
Abstract: 688,639. Calculating-apparatus. ABEILLE, M., and AQUILECCHIA, V. April 11, 1950 [April 12, 1949], No. 8934/50. Class 106 (i). A pocket logarithmic calculator comprises a rotatable drum 6 mounted within a casing 1 and marked on its periphery with logarithmic and cologarithmic (colog. x=log. 10-log. x) scales read by a magnifying eyepiece 7 against a fixed index mark on a window 8. A movable index is frictionally engaged with the drum; as shown, this index is marked on a coaxial disc 10 provided with a frictional coupling 14 adjustable by a set-screw 15, and with a spring detent 18 normally positioning the disc with its index accurately in register with an index mark at a window 5. A finger pinion 9 is engageable with and drives the drum 6 alone, and a pinion 11 drives the disc 10 and with it the drum 6. Multiplication is carried out by adjusting the drum 6 by means of its pinion 9 to bring the multiplicand on the log. scale to the index mark in window 8. The disc 10 and drum 6 are then rotated together until the multiplier on the colog. scale registers with the index mark. At this stage, the index mark on the disc 10 will have been shifted away from the index at window 5 by an amount representing log. 10 - the logarithm of the product. To find the product, the drum 6 is restored to zero by means of its pinion 9, and the disc 10 then restored, continuing its previous direction of rotation. This rotation of the disc 10 is transmitted to the drum 6 which now shows the product on its log. scale at the index line on window 8. The main graduations of the scales are repeated by scales on the circular face of the drum, windows (not shown) being provided in the casing for reading these scales. The drum 6 also includes log. scales of the trigonometrical functions and uniformally graduated number scales.

Abstract: 712,991. Photomechanical printing surfaces. KALLE & CO., AKT.-GES. April 18, 1951 [May 19, 1950; Sept. 5, 1950; Dec. 22, 1950], No. 9104/51. Class 98(2) A support as of zinc or aluminium is coated with a solution of unsaturated ketone having the grouping in which x and y stand for 0, 1, 2 or 3 provided that the sum of x+y equals at least 2, or one of the groupings in which X in each case stands for O, S or NH, and the coating is dried, exposed under an original, developed with a dilute acid such as phosphoric acid and the developed surface rubbed with greasy ink in the presence of water. Only the areas on which light has impinged take the greasy ink and the material serves as a planographic printing plate. The unsaturated ketones may be prepared by condensing ketones characterized by one or two CH 2  groups directly linked with the CO group on one or both sides with saturated or unsaturated aldehydes and may be coated on the support preferably in the dark in a solvent such as methyl or ethyl alcohol, dioxane, pyridine, benzene, methyl ethyl ketone or glycol monomethyl ether. A polymerization inhibitor such as hydroquinone, p-benzoquinone, p-toluquinone, chloranil (2: 3: 5: 6-tetrachloro-p-benzoquinone) or a dye of the thiazine series such as thionine blue, toluidine blue or methylene blue may be included in the layer. Unsaturated ketones containing aromatic or heterocyclic radicals are preferred and substituents may be present but water-solubilizing groups are disadvantageous. Numerous ketones are described and may be used in admixture to avoid crystallization. In. twenty-one specific examples the support is grained, roughened or superficially oxidized aluminium foil or plate. Storage qualities of the light sensitive plates are illustrated in Examples 17-21, showing that roughened aluminium plate coated with a-cinnamylidene-γ-furfurylidene-acetone containing methylene blue can be stored at 40C with 85 per cent relative humidity for four days without change showing in the layer, or for fifteen days if α-cinnamylidene-γ-citrylidene-acetone is present in the layer as well. The last mentioned substance together with cinnamylidene-2- acetyl-thiophene and p-benzoquinone or p-toluquinone enables production of plates which may be stored for several months at room temperature.
