Title: Self regulating shutoff valve
IPC: F17C13/04
Filed: 1976-11-04
Abstract: 1536959 Valves PENNWALT CORP 4 Nov 1976 [5 Nov 1975] 45968/76 Heading F2V A self-regulating valve assembly for controlling gas flow from a gas source to a lowerpressure gas user, comprises an upstream pressure-reducing valve 16A and a downstream shut-off valve 18A. In use, a predetermined low pressure created in line 50 by the user causes the valve 18A to open whereafter a lower predetermined pressure developed in chamber 40 causes the valve 16A to open. In the event of a pressure rise in the line 50 due, e.g., to a malfunction, the shut-off valve closes and thereby isolates the relatively high pressure gas in the housing part 10 which is made stronger than the other housing parts (e.g. part 10 is of brass and part 12 is of plastics). Both valves are actuated by a respective diaphragm 30, 32. The diaphragm 30 is associated with manually-operable means 44 for lifting it to an inoperative position in which it is latched by a pair of parallel rods 64, 66, the diaphragm being automatically released when the pressure in chamber 40 is intermediate the above-mentioned predetermined pressures.

Title: Apparatus for Folding the Edges of a Flexible Sheet
Inventor: BOCCA ALBERTO
IPC: A43D8/44
Filed: 1967-10-24
Abstract: 1,168,898. Folding edges of non-metallic sheet material. A. BOCCA and M. PAGANI. 24 Oct., 1967 [9 March, 1967], No. 48231/67. Heading B5K. Apparatus 10 for edge folding a flexible workpiece, e.g. a footwear upper 15, comprises a device for making cuts or indentations including a blade 44 and a counterblade 41, drive means for operating the cutting device and control means operable independently of the drive means for controlling cutting operations on the workpiece. The upper 15 slides on a table 14 and its outer edge to be folded runs on a fixed member 16 having an upper surface curved to effect the subsequent edge folding. A presser foot 18 is fixed to a lever 20 pivoted at 21 and connected by a pin and slot connection 23, 24 to a lever 26 pivoted at 27. The other end 28 of the lever 26 is vertically reciprocable, e.g. by a pedal-actuated vertical rod, in a fixed slot 29. A lever 30 pivoted at 31 has a pin 35 adjustably positioned in an abutment 33 thereon. The pin 35 is slidable through a bore 37 in a fixed part 38 of the apparatus and the free end can engage the lever 20. The lever 30 is held against a projection 39 of the part 38 by a spring 73. The counterblade 41 is secured by a pin 42 in a slot 40 in the lever 30 so as to be adjustable towards and away from the presser foot 18. The blade 44 is U-shaped, one prong of the U having a cutting edge 45 and the other prong 46 having a slot 47, and is fixed to the counterblade 41 by a screw 43. The blade 44 and the oounterblade 41 are urged towards each other by a spring (49), Fig. 4 (not shown). The slot 47 is engaged by a pin 50 on a bar 51 fixed to a rod 52 having an enlarged diameter portion 54 having a roller 55 projecting downwardly therefrom and an abutting inclined plane 56 against which a frusto-conical end 57 of a rod 58 is urged by a spring 65. The rod 58 is vertically reciprocable in a fixed sleeve 59 and is pivoted to a rod 61 connected to a box 63 which allows a restricted reciprocation only. The rod 61 is connected to a rod 64 linked to a pedal (not shown). The rod 52 is urged to the left of Fig. 1 by a spring 72 so that when the end 57 is clear of its seating 56, the roller 55 is pressed against a cam 67 keyed to the mainshaft 12 of the machine. In operation, to cut or indent the edge of the upper 15 being folded, the pedal connected to the bar 58 is depressed and the roller 55 follows the cam 67 so that the bar 52 reciprocates the blade 44 through the pin and slot connection 50, 47, the cutting movement of the blade taking place in the same direction as the direction of folding of the edge of the workpiece. Due to the action of the lever 20 on the pin 35 the blade and counterblade assembly are lifted from the upper 15 when the presser foot 18 is lifted and when the foot 18 is lowered this assembly is positioned at a height determined by the projection 39.

Title: Method of converting cephalosporin c to a derivative thereof
IPC: C07D501/18
Filed: 1970-10-12
Abstract: 1324419 N-haloalkanoyl derivatives of cephalosporin C ELI LILLY & CO 12 Oct 1970 [17 Dec 1969] 48320/70 Heading C2A Cephalosporin C is converted to an N-haloalkanoyl derivative of formula wherein R is an α-halo or α,α-dihalo-C 2 -C 4  alkanoyl group, by acylating the amino group in the adipoyl side chain with a corresponding haloalkanoyl halide or anhydride. The cephalosporin C may be treated in aqueous solution, e.g. a productive fermentation broth which preferably has been filtered and if necessary concentrated, to convert it to the said derivative which is easily extracted from the aqueous medium with a water-immiscible solvent such as ethyl acetate. The acylating agent is preferably an α-halo or α,α-dihaloalkanoyl chloride or mixed anhydride (e.g. acetic chloroacetic anhydride). The solvent extraction is best conducted at acid pH and immiscible solvents used include propyl or butyl acetate, nitriles and ketones. Alkyl esters may be mixed with one tenth to one volume of C 2  to C 4  alkanol. The derivative may subsequently be isolated by, e.g. adding an alkali to the solution to precipitate it as a salt. The formation of the derivative provides a convenient means for separating cephalosporin C from its productive fermentation broth.

Abstract: 1469608 Plywood HASHIMOTO DENKI CO Ltd 25 Nov 1975 [26 Nov 1974 17 Feb 1975 (2)] 48348/75 Heading B5L A core block for plywood comprises a thin wooden sheet 1 folded in regular zig-zag manner, the sheet having outwardly facing incisions 2 at the folds and the incisions extending in the direction of the wood grain. The portions of the sheet lying between the folds may contact each other and be adhered together to form a solid core block 4 to which outer wood laminµ 6, 7 may be adhered to form plywood 8, Fig. 2. Alternatively the inter-fold portions may be arranged to form a triangular structure, Fig. 3, to which the outer plies 6, 7 are adhered at 10. In a method of and apparatus for making the block the wood veneer 1 is fed between cooperating toothed rolls 11, 12 having knives 15 at the roots of the teeth so as to provide incisions at the outwardly facing crests of the waveform sheet produced by the rolls. The wavy, incized sheet is forwarded between restricting guides 16a, 16b (or between spaced belts Fig. 6, not shown, the speed of which is controlled) to gather the material of the sheet into the requisite block 4, adhesive being sprayed on the surfaces and heat applied if desired to set the adhesive. Since the veneer sheet 1 as initially supplied has flexibility in one direction only (due to the formation of fine surface cracks in one surface in the original veneer peeling process) it is preferably fed between a rubber covered roller 28 and co-operating pressure bar 30 to form similar surface cracks in the other face and thus provide flexibility in both directions before being fed to the shaping and incising rolls 11, 12.

Specified amines are primary monoamines and polyamines of aromatic character derived for example from benzene, condensed ring systems with 2 to 4 benzene nuclei to which heterocyclic rings may be anellated, heterocyclic compounds and derivatives thereof which contain side chains and/or inert substituents such as carboxylic, sulphonic, hydroxyl, amino and nitro groups, and halogen atoms.  Diazotizing agents specified are solutions of nitriles in acids, nitrous acid esters or nitrosyl compounds. Two types of apparatus are described for carrying out the process.  Examples are given for the diazotization of sulphanilic acid, metanillic acid, p-chloroaniline and aniline, and for the reduction of the diazo compounds to give hydrazines.

The pulse spacing is greater than the two-way transmission time to the farthest object of interest. In the embodiment a storage-display tube includes a planar-concave fibre-optic plate D1, Fig. 2 (not shown), a bi-concave fibre-optic plate D2, and a concave-planar fibre-optic plate D3; a photo-cathode D4 is deposited on the concave surface of plate D1 the electrons from which are focused by electrodes D5, D6 on to an aluminized phosphor D7 deposited on the first curved surface of plate D2. A second photo-cathode D8 receives light from phosphor D7 and the ensuing electrons are focused by electrodes D9, D10 on to a storage mesh D12 of known construction. An electron beam produced by a source D13 floods a phosphor D14 on plate D3.
