Title: Improvements in or relating to locking means for pivotally interconnected members
IPC: G03B21/58
Filed: 1946-11-21
Abstract: 620,523. Stays for hinged articles. CATTLE, Ltd., R., and WARREN, G. A. Nov. 21, 1946, No. 34552. [Class 65 (i)] A stay e, for a member hinged to a base, is pivoted at one end to the member and is provided at the other end with a pin h adapted to slide along the top surface of a rib a forming part of the base, the pin engaging in a notch k when the hinged member is in its erected position. A second pin j, connected to the stay by a link g, is adapted to move. in a slot n. The surfaces of the slot and base are formed with cams with which the pins co-operate, the arrangement being such that when the hinged member is moved beyond its erected position the first pin is lifted out of the notch and is maintained above the level of the said top surface until, during the collapsing movement, it has been moved clear of the notch. The slot ends in a pocket t situated beneath the notch at a distance from the latter less than the distance between the axes of the pins. The lower surface of the slot is formed towards the notch with humps r and s, and continues beyond the latter at a distance from the top of the rib greater than the distance between the axes of the pins. The upper surface of the slot is formed between the humps with a recurved portion u and above the hump r with a cutaway portion x. The link is formed with a projection v, adapted to co-operate with a lug w situated near the inner end of the hump r, to deflect the pin j on to the recurved portion u when the hinged member is moved beyond its erected position while being raised. Release of the said member then allows the pin h to engage .the notch k and the pin to' drop into the dip between the humps. Collapsing the hinged member is effected by again raising the latter beyond its erected position, when the pin h rides up an inclined continuation m of the notch while the pin j is drawn over the hump s and lodges in the pocket t. Release of the hinged member then causes the link to pivot on the pin j, thus carrying the pin h clear of the notch and on to the top surface of the rib. The cutaway allows the pin j to rise when the link rides over the lug w.

Abstract: 1473502 Bookbinding STRACHAN & HENSHAW Ltd 19 July 1974 [20 July 1973 18 Sept 1973 16 Oct 1973 20 Nov 1973 19 April 1974] 34713/73 43807/73 48203/73 53749/73 and 17356/74 Heading B6A In bookbinding, two webs 1, 2, Fig. 1 are printed at 3, 4 on their one face and at 5, 6 on their other face, and are longitudinally slit at 9 into four ribbons each. The ribbons are collated at 10 into an eight thickness web assembly which is cut into sheets and folded either transversely, Fig. 2, or longitudinally, Fig. 6, into signatures. The printing is such that each signature bears pages from two books, the pages being printed in opposite directions at opposite ends of the signature. As described 256-page books are to be made and batches of four signatures comprising sixteen pages of one book and sixteen pages of another, are formed by alternately directing four such signatures into one pocket, e.g. 13, and four into another, e.g. 14, Fig. 2. With transversely folded signatures, the pockets are rotary flyers which direct the signatures 25, 26, spine first, into overlapping arrays 30 on transversely moving conveyer belts where pushers and retarders move the arrays into vertical piles. The conveyer from pocket 14 has a U-turn so that the associated signature piles are rotated through 180 degrees. They are then advanced together with signature piles from pocket 13, spine to spine, to a plough 41, Fig. 3b, which turns them into a block with its spine lowermost ready for binding. The block is cut transversely to its spine to produce two books. With longitudinal folding, the signatures are directed by gripper cylinders 70, 71, Fig. 6, on to conveyers, and are turned through 180 degrees and ploughed together by the conveyers of Fig. 10. One conveyer may be operable in either direction and can co-operate with a transfer wheel to eliminate the 180 degree turn for simple binding of signatures not printed with oppositely directed pages.

Title: Improvements relating to bridges or bridge-like structures
IPC: E01D15/133
Filed: 1945-12-21
Abstract: 605,404. Bridges; roof trusses &c. HAMILTON, A. M., and BRITISH INSULATED CALLENDERS CABLES, Ltd. Dec. 21, 1945, No. 34747. [Classes 20(i) and 20(iv)] Relates to bridges or bridge-like structures, e.g. trusses, constructed from standard parts and in order to effect close approximation to exact span lengths, even if those lengths are unknown when the standard parts are made the bridge &c. is composed of standardized bays in two lengths x and y, the difference between x and y being a fraction of each. By combinations of these two standard bays the steps between the bridge lengths so obtainable are much less than the smallest steps obtainable with standard bays all of the same length. Above a certain bridge length, the length of every step is the Highest Common Factor of x and y. If this H.C.F. is z it will generally be convenient to make z=y-x. In the example shown of a bridge required to span two unequal spaces L and M, an approximation to L is given by 2 standard bays of length x and 6 standard bays of length y; and an approximation to M is given by 6 standard bays of length x and 1 standard bay of length y. The necessary adjustments in connecting two different standard bays are provided by transition cords t and special gusset plates c. The lines of bolt holes dx, dy in the gusset plates are at different angles to suit the different angles of the two types x, y of bay. Other connections are similarly dealt with. Specifications 423,926, 423,996 and 562,601 are referred to.

Title: Ferrous salts of amino acids
IPC: A61K33/26
Filed: 1954-12-06
Abstract: Ferrous salts of glutamic, aspartic or pyrrolidone-carboxylic acid are made by reacting an alkaline earth metal salt of the acid such as the calcium or barium salt with a water-soluble ferrous salt whose anion forms a water-insoluble salt with the alkaline earth metal, in the presence of metallic iron in an atmosphere of a non-oxidizing gas which is inert under the reaction conditions and separating the ferrous salt, for example by removing the insoluble salt and evaporating the solution to dryness.  The reaction is suitably carried out by heating calcium hydroxide or barium hydroxide with the acid at a temperature of 90 DEG  to 105 DEG  C. in aqueous suspension, in the presence of metallic iron and in a nitrogen atmosphere with the optional addition of a filter aid, adding ferrous sulphate and metallic iron, replacing the nitrogen atmosphere by carbon dioxide, separating the alkaline earth metal sulphate, and evaporating the solution to dryness.  The products are used as pharmaceuticals in the treatment of iron deficiency. Examples describe the preparation of ferrous glutamate monohydrate <FORM:0756312/IV(a)/1> and ferrous - L - pyrrolidone carboxylate monohydrate.

Abstract: 1454855 Fuel injection apparatus DEUTSCHE VERGASER GmbH & CO KG 13 Aug 1974 [13 Aug 1973] 35654/74 Heading F1B I.C. engine fuel injection apparatus comprises a fuel flow regulator actuated by an air-flow sensitive device in the induction pipe which is coupled to a pneumatic booster for increasing the sensitivity of the device. A vane 15 mounted on a shaft 14 rotates a three dimensional cam (25), Fig. 2 (not shown), in response to changes in air-flow, the shaft being coupled to a piston 17 which responds to the difference between the pressures upstream and downstream of the vane to act as a booster. Cam (25) is moved along the shaft in conjunction with movement of a throttle valve (12), the rotational and translational motion of the cam controlling the fuel flow regulator in order to maintain the correct flow of fuel throughout the operating range of the engine. A pump 46 transfers fuel from a tank 47 to the regulator to via a non- return valve 61 and a port 81, pressure being maintained by a constant pressure valve 54 which allows fuel to return to the tank via a valve 56 operated by valve 61. When pump 46 stops, both valves 56, 61 close thus preventing return of fuel to the tank. From each distributer port (one for each cylinder) of the regulator, fuel passes to a corresponding differential diaphragm valve 41 and subsequently via an orifice 97 into an injector nozzle 43. The injection rate is governed by a pressure control valve 59 responsive to engine temperature, which allows fuel to enter chamber 93 on the side of a diaphragm 94 opposite to orifice 97, a valve needle 95 which co-operates with orifice 97 being mounted on the diaphragm. The pressure in chamber 93 is governed by the compression of spring 85 which in turn is controlled by an expansion device 86 responsive to engine temperature. The engine is started cold on a rich mixture, as it heats up after starting, the compression of spring 85 increases causing an increase in the pressure in chamber 93 and a consequent decrease in the amount of fuel passing through nozzle 43, thereby weakening the mixture for normal running. In another embodiment, Fig. 3 (not shown), the movement of cam (25) along shaft 14 is governed by a device responsive to engine speed.
