Filed: 1959-04-02
Abstract: 911,303. Terminal blocks; binding-posts; wire couplings. LANCZI, L. E. June 20, 1960 [April 2, 1959], No. 11303/59. Class 38 (1). An electric terminal block is formed at its base with two spaced projections 25 which embrace and fit closely against the sides of an mounting rail R having an undercut slot 26 extending longitudinally of its outer surface, and has on its base between the projections a spring clip 35 compressible to pass into the slot in the rail and then expanding into the under cut portion of the slot to hold the terminal block firmly but detachably in engagement with the rail. A locking bar 29, in operative position as shown, holds the tips 39 of the clip apart thereby preventing withdrawal of the terminal block from the rail. Cable ends are secured by a leaf spring 13 compressed by screws 10, 12. Screw 11 is for interconnecting terminal blocks.

Abstract: 183,249. Bloxam, A. G., (Technochemia Akt.-Ges.). April 20, 1921. Proofing.-Animal fibre, such as hair, is treated with chlorine in known manner. The exidized fibre is then dipped in a bath containing excess of alkali such as caustic soda, or sodium carbonate. The product is dried, then treated with boiling soap solution, and then, optionally, with acetic acid, or calendered. To the alkali bath may be added soaps, molasses, glucose, glycerine, or other substances which have a softening action. The treated fibre may be subsequently impregnated with a waterproofing and softening agent such as beeswax, paraffin, ceresin, stearin, spermaceti, resins, or the like, either melted or in solution or after saponification. The waterproofing and softening may be effected immediately after the treatment with chlorine.

Title: Process for the production of carboxylic acid amides and imides
IPC: C07C233/00
Filed: 1946-04-15
Abstract: N-Substituted amides of carboxylic acids are obtained by reacting the acids with organic phosphazo compounds.  The latter may be of the type RN=PNHR, where R is an aliphatic, alicyclic, aromatic or heterocyclic radicle which may be substituted, e.g. by halogen or an alkyl, alkoxy, sulpho, additional amino or substituted amino grop but not by a carboxylic group or an o- or p-nitro group.  The cyclic dimers of phosphazo compounds of the above type may also be used, or alternatively the phosphazo compounds may be taken in the form of the crude reaction product obtained from phosphorus trichloride and the corresponding primary amine.  Mono- or di-carboxylic acids may be treated with the phosphazo compounds, and in the latter case the product may be an N-substituted mono- or di-amide or an N-substituted imide.  The reaction may be effected at atmospheric or raised temperature, preferably in the presence of a solvent; a number of solvents are specified.  Examples are given of the preparation of: (1) N-octylpropionamide from propionic acid and a reaction product of phosphorus trichloride with octylamine; (2) p-nitrobenzanilide from p-nitrobenzoic acid and phenyl phosphazoanilide, obtained from phosphorus trichloride and aniline; (3) N-butylbenzamide from benzoic acid and a reaction product of phosphorus trichloride with butylamine; (4) N-cyclohexylbenzamide from benzoic acid and a reaction product of phosphorus trichloride with cyclohexylamine; (5) nicotinic acid anilide from nicotinic acid and phenyl phosphazoanilide; (6) N-benzoylsulphanilic acid from benzoic acid and a reaction product of phosphorus trichloride with sulphanilio acid; (7) N : N1-diphenylmalonamide from malonic acid and phenyl phosphazoanilide.  Reference is made also to the use of the phosphazo compounds obtainable from methylamine, ethylamine, propylamine, amylamine, dodecylamine, stearylamine, cyclopentylamine, naphthylamines, and amino derivatives of pyridine, quinoline, carbazole and diphenylene oxide.

Abstract: 921,603. Telephone interconnection systems. H. A. CORRIGAN. April 9, 1959, No. 11992/59. Class 40 (4). In an interconnection system, suitable for use in hospitals, having a central station and remote stations, battery feed is supplied to all remote stations over a common pair of wires, and a third wire individual to each station connects the latter to the central station; each remote station and the central station being equipped with audio and visual signalling means controllable over the third wire, both at the central and remote stations. As shown a patient at a remote station wishing to call a nurse momentarily closes contact 15 to complete a series circuit over wires W, lamp L1 at the central station, wire R1 and relay K at the remote station to wire B. Relay K then locks up in this circuit and also lights lamps 20, 21 which are respectively at the patient's bedside and outside his room in the corridor. At the central station an operator, warned by the lamp L1, throws switch S1, which disconnects L1 and connects up a telephone via a voiceoperated amplifier 61 and opens the circuit for relay K, which on releasing extinguishes lamps 20, 21 and connects up a transducer 24. Telephone communication is then established over wires R1, W. A passing nurse observing the corridor light may, on attending the patient, momentarily open contact 13 to release K thus cancelling the call to the central station. The switching of the amplifier 61 may be by means of a manually operated " talk-listen " switch instead of a voice-operated switch.

Title: Process for the preparation of cyclopentanophenanthrene derivatives
IPC: C12P33/00
Filed: 1954-04-26
Abstract: 21-Hydroxy steroids of the pregnane and 19-norpregnane series are prepared from the corresponding 21-desoxy compounds by oxidation with a strain of Aspergillus niger by dispersing a said 21-desoxy compound in a nutrient medium containing the fungus, maintaining the mixture so obtained under conditions favourable to fungus growth for a period of time exceeding 48 hours and recovering the formed 21-hydroxy compound from said mixture.  The process is applicable to unsaturated and saturated pregnanes (both allo and normal series), and particularly to their derivatives containing hydroxy and keto substituents.  The preferred organism is Aspergillus niger (ATCC 9142), and the incubation time (at 28 DEG  C.) is normally from 96 to 120 hours, after which the steroids are extracted, e.g. with ethylene dichloride, and the 21-hydroxy compounds purified by chromatographic methods.  Examples are given of the oxidation of progesterone and its 11a -hydroxy-, 11b  - hydroxy -, 11 - keto -, 6b  - hydroxy, 17a -hydroxy -, and 19 - nor - derivatives to D 4-pregnen - 21 - ol - 3,20 - dione and the corresponding derivatives respectively.  D 4-19-norpregnen - 21 - ol - 3,20 - dione thus obtained from 19-norprogesterone is treated with acetic anhydride and pyridine to yield the 21-acetate. Specifications 745,636 and U.S.A.
