Patent GB-1025425-A (GB)
Title: Penicillins
IPC: C07D499/68
Filed: 1963-06-24
Abstract: 6 - (Acylamino) - penicillanic acids in which the a -carbon of the acyl group has a guanidine or substituted guanidine attached to it may be prepared by intimately contacting an a -guanadino or an a -substituted-guanadino organic acid with an ester of 6-aminopenicillanic acid, said ester being easily cleaned by catalytic hydrogenation, in the presence of a carbodiimide and catalytically hydrogenating the resulting reaction product to produce the corresponding 6-(acylamino)-penicillanic acid.  The ester of 6-amino-penicillanic acid is preferably the benzyl ester. Examples describe the production of a number of penicillins such as a -guanidino - benzyl-, a  - guanidino - methyl- and a -guanidino - 1 - naphthylmethyl - penicillin, and of acid-addition salts thereof, such as the hydrochlorides.  Benzyl - 6 - aminopenicillanate is prepared by reacting 6-aminopenicillanic acid with phenyldiazomethane.  a -Guanadino substituted organic acids are prepared by reacting the appropriate amino-carboxylic acid with a selected O-alkylisourea or an isothiourea S-alkyl ether, e.g. a -guanadino-phenylacetic acid is prepared by the reaction of a -aminophenylacetic acid with O-methyliso-urea. Other acids prepared in this way are a -guanidino - b  - phenylpropionic, -propionic, -p-methoxy-phenyl acetic, -a -furyl acetic, -cyclo-hexylacetic, -naphthyl acetic and -octanoic acids.

Abstract: 156,347. Baldwin, E. Oct. 16, 1919. Receiving and delivery devices for doors.-A milk-delivery device comprises a funnel e, the delivery-pipe d of which is rectangular in cross-section and passes through a correspondingly-shaped aperture b in a house door a, the aperture being normally closed by a pivoted part n of a slide m disposed in a frame k at the back of the door. The pipe d on passing through the aperture b moves the part n, and milk poured into the funnel e is delivered to a can q placed in a box secured to the door. Upon removal of the pipe d, the slide drops and closes the aperture b. The funnel may be supported by a stay g, which acts as a stop to limit the insertion of the pipe; a fixed collar or projection may be employed for this purpose. A sieve h and plug j, fitted to the funnel, are removable for cleaning purposes. The aperture b may extend through a boss c screwed to the door and provided with a pivoted closing- plate u and slot w to receive labels denoting the requirements of the householder. In a modification applied to a door with a letter-box slot, the can for receiving the milk has a hinged sloping lid, over which the letters can elide, and a hole in the back through which the funnel pipe passes. This can is suspended by ears from studs on the back of the door. Reference has been directed by the Comptroller to Specification 10246/93, [Class 84, Milhing Ac.].

The supporting structure for the multiple filament of a discharge tube comprises two concentric tubular members, each having radial projections to which the filament strands are attached, and a coaxial tensioning rod; the filament strands are supported under tension without being welded to the support. In Fig. 1 the two tubular members 20, 21 are attached via plates 3, 22 to the respective metal envelope parts 2a, 2, which act as filament terminals. The lower ends of the members 20, 21 have reduced cross-sections as at 25, 26, with radial apertures 27 therein, which construction is stated to equalize the temperatures of the two members. The lower ends of these members have radial projections as at 28, 29; they are assembled so that the projections 28 of one member interleave with the projections 29 of the other member. Each projection 28, 29 has two vertical grooves 32 and two holes 30, for locating the filament wires. Each filament consists of a bifurcated wire 9, the top ends 31 being bent back and fitted into holes 30 on two adjacent arms. The bight of the filament is bent at right-angles, and engaged by the hooked ends 41 of a clamp 42, the closed part 43 of this clamp being secured between two discs 33, 34 held together by rivets 44 and a pin 45. A rod 10 bears against disc 33 at its lower end, and is urged downwards to hold the filament wires in tension. The amount of tension is controlled and adjusted at its upper end by means comprising a cap screw 8 and a spring 13. To remove and replace a defective filament wire, the cap screw 8 is loosened to reduce the tension, and pin 45 loosened to enable the defective filament to be detached from clamp 42.

Title: An improved process for the separation of cobalt and nickel
Inventor: MERRE MARCEL DE
IPC: C01G53/10
Filed: 1954-09-06
Abstract: Cobalt and nickel, present in sulphate or chloride solutions in a weight ratio Ni/Co higher than 2/1 , are separated by precipitating cobalt hydroxide at a pH not less than 3 with nickelic hydroxide until said ratio in the solution is more than 100/2 e.g. 200/1 ; separating the precipitate, dissolving in the presence of SO2 as reducing agent and treating (as described and claimed in Specifications 650,595, 655,149 and 683,679, with Co, Fe or an alloy of Co and/or Fe in the presence of S, As, Sb, Te or Se to precipitate nickel as a cobalt-containing residue and recover a solution of cobalt with very little nickel (e.g. 0.5 parts by weight of nickel per 100 parts by weight of cobalt); the residue is brought into solution as sulphates or chlorides and mixed with the initial solution.  In the example, nickelic hydroxide is added at a pH of 3.5 to a cobalt and nickel sulphate solution to precipitate cobalt, sulphuric acid is progressively added until the Co/Ni ratio in the solution is 0.4/100.  The mixture is filtered: a portion of the purified nickel solution is used to obtain commercial nickel products and a portion is used to provide nickelic hydroxide for a subsequent operation by precipitation with sodium hypochlorite at a pH of 8; the precipitate is redissolved with aqueous sulphur dioxide and cobalt and sulphur are used to precipitate a residue of sulphides of nickel and cobalt in the ratio 4.2:2 which, after separation from the desired purified cobalt sulphate solution, is roasted in air at 550 DEG C. and dissolved in sulphuric acid for recycling to the first stage.
