Patent GB-661358-A (GB)
Title: Process for the production of penicillin compounds of urea and urea derivatives
IPC: A61K31/43
Filed: 1948-02-27
Abstract: Compounds of penicillin with urea and creatine are manufactured by reacting penicillin or a salt thereof (e.g. the sodium, calcium or ammonium salt) with urea or creatine or a salt thereof in a common solvent, and, if desired, separating the resulting compound in solid form.  In examples: (1) urea is added to a solution of penicillin in absolute methyl alcohol, which is then concentrated and penicillin urea is precipitated by adding chloroform; (2) urea citrate is added to an aqueous solution of sodium penicillin, and penicillin urea citrate is isolated by lyophilization; (3) creatine adenylate is added to an aqueous solution of sodium penicillin to produce a solution of creatine penicillin and sodium adenylate. p   The Specification as open to inspection under Sect. 91 comprises also the production of compounds of penicillin with other derivatives of urea, e.g. alkyl and acyl (especially higher aliphatic acyl) ureas and cyclic urea derivatives (examples of all of which are specified), phenylurea, thiourea and guanidine. Reference is also made to the reaction of urea derivatives with esters of penicillin.  In an additional examples, "imidazole caproic acid" of the formula <FORM:0661358/IV (b)/1> is added to a solution of sodium penicillin in hot absolute methyl alcohol and the solution is evaporated to dryness in vacuo.  This subject-matter does not appear in the Specification as accepted.

[Class 112.] A knife for separating and trimming the underply of materials, such as the linings of shoe uppers, is mounted on a bracket arm overhanging the work support, and is mounted for ready removal out of operative position. The knife has a depending cutting edge 48 opposed to the direction of feed, a ply separating pin 47, an edge guide 51 and a shank 52 for securing it to the carrier 44. The carrier 44 has a bent part 43 by which it is connected to the operating means. The horizontal arcuate movement of the knife is imparted from the main shaft 4 by the following mechanism, eccentric 34, strap 33, rock shaft 30, arm 38, extensible link 27, arm 26, rock shaft 24 and arm 56. The rear end of the carrier 43 is reduced in thickness to form a flexible tail 53 yieldably entering a notch in the depending part 55 of the arm 56. When not desired, the knife is moved to inoperative position by depressing the tail 53 out of the notch and turning it through 90‹ about the pivot 41. The knife carrier is held in operative position by its engagement with the notch in the part 55 and by the entry of a stud 39 into a notch 60.

Abstract: 1280421 Rotary table moulding apparatus R ZIPPEL [trading as RICHARD ZIPPEL & CO KG] 3 Feb 1970 [29.March 1969] 5095/70 Heading B5A [Also in Division G3] A plastics material moulding plant for preforming a succession of mould filling operations is controlled by a cross-bar switch connected in an electrical circuit for determining the amount of material delivered by a metering means during each mould-filling operation. As shown, a plurality of moulds 2, such as are used with foaming plastics, are arranged near the periphery of a rotatable head of a mould conveyer table 1 which is rotated in steps to successively position the moulds under a discharge head 3. The component plastics materials of a moulding mixture are fed to the head 3 through conduits 6, 7 by the movement of metering pistons 8, 9. The head 3 comprises a nozzle attached to a mounting member 5 which is disposed in guides 4 and displaced in synchronism with the pistons 8, 9 to ensure uniform filling of the moulds. Nozzle cleaning is effected when a number of adjacent moulds on the table are empty. The filling of the moulds is controlled by a cross-bar selector switch 17 of which the horizontal bars 16 are selected by a contact device 14, driven in synchronism with the table through gears 12, 13, which engages contacts 15. Each horizontal bar is linked to a vertical bar 18 by inserting plugs through holes 19 to select a desired induction of plastics material by limit switch contacts 20 which engage a selector 21 coupled to the pistons 8, 9 and a corresponding displacement of the member 5 through a selector 23 and limit switch contacts 22. When the contact is engaged by the selector, the return movement of the metering pistons is initiated and the plastics materials are forced into the discharge head 3. The materials in the head are mixed and discharged into the mould by the return movement of the head 3. The table 1 is subsequently rotated to cause the next open mould to be carried under the discharge head 3.

Assume a route from TA to TF, units I, II and III, when their associated track elements are set for the route, pass signals from input terminal 1 to output terminal 4 and from terminal 3 to terminal 2, units XI, VI, VII and IV, when their associated track elements can provide flank protection and ahead protection, pass an input signal on terminal 1 to output terminal 2.

Input signals at terminal 1 can provide inputs to cores a or b and input signals at terminal 3 to cores c and d. Output terminals 2 and 4 are coupled to cores a, d and b, c, respectively, and the transmission of a signal by a core can be inhibited by signals from the associated route apparatus on lines A, B and C.

Abstract: 667,628. Liquid raising by air pressure ; injectors. GOLLNER, D. March 1, 1950, No. 5222/50. Class 71 and 102 (ii) A device for raising liquid by compressed air comprises a liquid collecting tank 1 having a vent opening 11 controlled by a float actuated exhaust valve 10 whose rod 9 carries a piston 20, co-operating with a recess in a hood 2, which is acted upon by the compressed air in one direction or the other to produce an acceleration of the opening and closing movement of the valve independently of the movement of the float. The lower conical surface of the piston has an effective area greater than the effective area of the upper surface so that when the piston is partially moved from its recess the air acts on its underside to raise the rod 9 which is corrected to the float lever 5 by a lost motion correction 7, 8. A second valve 21 controls the passage of air from the admission channel 15 and chamber 16 into the tank. through ports (not shown) in the hood 2. An injector 22, 22a is supplied with compressed air through a pipe 23 from the chamber 16 to produce suction for drawing liquid into the tank. If the liquid enters by gravity the injector may be immobilized by a manual valve. During the opening movement of the valve 21 a. separate injector action is produced by an annular nozzle 14 from which the air passes directly into the vent 11 which forms the combining nozzle. In another embodiment the exhaust valve 10 is situated on the valve rod lower than the air admission valve and the piston. The exhaust valve co-operates with its seating to pack the combining nozzle of an injector which during its closing movement produces a temporary suctional effect in the tank to assist the filling. No separate injector is fitted.
