Abstract: 1,045,547. Safe load indicators for jibcranes. RUSTON-BUCYRUS Ltd. May 13, 1965 [May 27, 1964], No. 21904/64. Heading B8B. A safe load indicator comprises a device 15 which measures the force on the A-frame by means of a strut which is deformed under load and a device 14 which registers the radial movement of the jib, the two devices being linked by a cable 16. A link 17 connects the jib 12 to the device 14. The device 15 comprises a strut 18, Fig. 3 (not shown), which is attached to its ends to a strut 13 of the A-frame and when unstressed is buckeled away from the latter. When the crane is loaded the strut 18 progressively straightens under tension and this movement is magnified and transmitted to a micro-switch 23 by a lever 22. When the micro-switch is closed the alarm signals are operated. The micro-switch plungers abut adjustable screws 35 which are moved towards and away from the switch to compensate for the jib angle of the crane by a cam in the device 14 and the control cable 16. The screws 35 are mounted near the ends of spring arms 33. If this arrangement is not sufficiently sensitive the strut 18 may be replaced by two levers of unequal length pinned together and to the strut 13. The lever 22 would then be mounted on the shorter of the two links. The length of the links would be such that they were just out of line at the maximum safe loading.

Title: Harvesting machine with detachable harvesting attachment
IPC: A01D41/16
Filed: 1973-05-09
Abstract: 1427174 Removably attaching harvester headers DEERE & CO 9 May 1973 [9 May 1972] 22082/73 Heading A1F A header is removably attached forwardly of a pivotal harvesting machine conveyor by lower, rear header projections which engage within respective locking brackets 16, Fig. 4, fixed to a transverse bar 15 mounted for transverse motion relative to the conveyor, The bar is movable between bracket-projection engagement and disengagement positions. In the simplest form Figs. 2, 3 (not shown) movement is effected by a lever pivotally mounted on the conveyor and lockable in either of the two positions. The header is also removably mounted by upper elements which cooperate with upper elements on the conveyor. In Figs. 4, 5 the bar is held in its projection disengaging position (solid lines) against the bias of tension spring 44 by the engagement of rotatable pawl 48 and bar notch 54. When the header is positioned for mounting it pushes a rod 39 against the bias of a spring 41 such that its attached leaf spring 47 pushes pawl 48 out of the notch 54. Bar 15 then slides under the bias of the spring 44 such that the elements 16 lock the header projections. In Fig. 7, the header pushes spring biassed rod 60 such that its spring loaded slide 61 moves with it to disengage from bar notch 54. For locking the bar 15 in its projection disengaging position against the bias of its spring 44 Fig. 4, the slide is pushed forward into notch 54 by push handle 67 such that a spring loaded ball 63 jumps from a groove 64. The ball re-engages in the groove when the rod moves forward after the header has been removed. In each of the embodiments shown the bar 15 is moved from its projection engaging position by the lever 25.

Abstract: 379,075. Weighing-apparatus. SEITZ-WERKE GES., Kreuznach, Germany. Aug. 5, 1931, No. 22238. Convention date, June 6. [Class 143.] Printed records, apparatus for giving. - The printing-mechanism of a pendulum-weight weighing-machine is provided with justifying means comprising a lever s carrying a number of knife-edges, one at least of which precedes the others when the lever is actuated to engage the knife-edges with a toothed disc m, the knifeedges being at such a distance apart that the toothed disc and the parts of the printing- mechanism connected thereto are adjusted or held to a setting to print the weight figure which is closest to the weight as indicated, the weight indication being unaffected by such justification. The spindle c, Fig. 3, of the pointer a is set by the weighing-mechanism and is rigid with a clutch plate d that is clamped during the printing operation. A projection e on the clutch plate co-operates with a follower arm f on a shaft g to set a stepped disc h, the steps i on which are adapted to arrest the feelers k of the printing-mechanism. The stepped disc h is rigid with the toothed justifying disc m, both discs being freely mounted on the shaft g and capable of a slight rotation relative thereto under the control of a spring-urged plunger p that is carried by the discs and enter a shallow recess in a lug o projecting from an arm m rigid with the shaft. The stepped disc h is justified, prior to the actuation of the feelers k, by a lever s that is rotatable to engage its knife-edges with the toothed disc. The lever carries two stationary knife-edges x, x<1> and a pair of integral knifeedges t, the latter being slidable transversely of the lever and being urged by a spring V to precede the stationary knife-edge in engaging the disc. The slidable knife-edges t engage either between two teeth, Fig. 4, or with a tooth therebetween and serve to move the discs into justified position where they are clamped by the fixed knife-edges. The knife-edges are adjustable longitudinally of the lever.

Abstract: 1,141,537. Laminates. J. BURNS Ltd. 25 April, 1967 [19 May, 1966], No. 22374/66. Heading B5N. A panel, e.g. a motor car trim panel, comprises a layer of synthetic plastics material, preferably polyvinyl chloride, and a rigid board, e.g. fibre board, constituting a support for the layer in which a portion of the thickness of the layer is constituted by foamed synthetic plastics material and in which areas of the layer are consolidated to a reduced thickness and have their foamed structure broken down to provide a quilted effect. The layer may be secured to the board by a polyvinyl chloride-polyvinyl acetate emulsion adhesive. The structure of the foamed layer is broken down by applying high-frequency welding elements to the surface of the layer remote from the board so as to compress the layer at the areas where the elements are applied. Plasticized polyester or polypropylene film may also be used. The layer may be formed by roll calendering with included foaming agent and the layer may be drawn off a roll when it is to be laminated to the backing. Alternatively the layer may be formed by extrusion followed by calendering, the foaming agent being added before or after extrusion. The edges of the polyvinyl chloride layer may be wrapped over the board and stapled or otherwise secured thereto, but preferably a further sheet of polyvinyl chloride is laid beneath the board and the margins of the two sheets high frequency welded together to encase the board.

Title: Improvements in the production of galactose
Inventor: DONNELLY JOSEPH
IPC: C08B37/00
Filed: 1960-06-28
Abstract: Crude anhydrous D(+) galactose produced by the degradation of an oligosaccharide is purified by dissolving it in methyl or ethyl alcohol or a mixture of one of these with water, removing undissolved impurities from the resulting solution and recovering the purified galactose from the solution by crystallisation. Alternatively the galactose may be recovered from the alcoholic solution by evaporating the solution, dissolving the residue in methyl alcohol or ethyl alcohol and crystallising the purified galactose therefrom.  The crude galactose used as starting material may be obtained by degrading an oligosaccharide, e.g. lactose, melibiose or raffinose with sulphuric or other mineral acid, neutralising the resulting solution with an alkali, concentrating the solution obtained and crystallising crude galactose therefrom.
