Abstract: 837,661. Hypodermic syringes. HENDERSON, E. May 27, 1958, No. 16891/58. Class 81 (2). An arrangement for re leasably holding a hypodermic needle of uniform dia meter on a syringe barrel comprises a resilient, tubular collet and a cap which dis torts the collet into gripping contact with the needle. The attachment member 18 is secured to the neck 16 of the syringe barrel 15 and has an external thread 19, which co-operates with an internal thread on a tapered cap 23 which, when tightened, compresses the collet 22, of artificial rubber, against the needle 26, as shown in Fig. 2. In order to limit the inward movement of the needle, a pin 25 extends across the bore 20 of the member 18 and is slightly offset so as not to obstruct the lumen of the needle. Various modifications are also described having other forms of stop, to prevent the needle passing into the barrel, and other forms of collet. In a further arrangement the attachment member is detachably mounted on the tapered nozzle of a syringe.
Patent GB-852304-A (GB)
Title: Preparation of ion exchange resins
IPC: C08F8/00
Filed: 1958-05-27
Abstract: Ion-exchange resins are prepared by reacting a poly (vinyl-aryl sulphonium) anion-exchange resin with a stoichiometric proportion of an iogenic nucleophile.  The sulphonium resins are the reaction products of cross-linked vinyl aryl polymers, e.g. polymers of styrene, vinyl toluene or xylene, chlorostyrene or dichlorostyrene, vinyl naphthalene or acenaphthene, containing halomethyl groups, and a sulphide containing one or two alkyl groups with 1 to 4 carbon atoms and/or one or two hydroxy alkyl groups, containing 2 to 4 carbon atoms, and they may be reacted as halides or sulphates, carbonates or other ionic forms. Cation-exchange resins are prepared by using iogenic nucleophiles such as alkali metal salts, e.g. sodium sulphite, salts of amino alkane sulphonic or phosphonic acids, amino carboxylic acids, and mercaptides of which examples are described e.g. sodium glycinate, disodium imino diacetate, sodium thioglycollate and trisodium mercapto succinate or anion exchange resins by using nucleophiles containing amine groups e.g. diethylene triamine, triethylene tetramine, N-(methyl)-glucamine or dimethylaminoethanol.  The sulphonium resin which may be in bead form and swollen, is heated at from 50 to 100 DEG C. for up to 60 hours with the nucleophile in aqueous or polar solvents, or in the dry state when adsorbed in the resin.  Alternatively the sulphonium resin may be prepared in situ in the presence of the nucleophile. Specification 845,005 is referred to.

Patent GB-886816-A (GB)
Title: Electronic relay
IPC: H03K17/60
Filed: 1959-05-19
Abstract: 886,816. Transistor switching circuits. SPECIALTIES DEVELOPMENT CORPORATION. May 19, 1959 [May 22, 1958], No. 16924/59. Class 40(6). An oscillator energized solely from a controlling circuit includes means for preventing oscillation when the input voltage is within a predetermined range, and provides an output for controlling a switching circuit. Fig. 1 shows an oscillator 10 controlling a voltage applied across terminals 41, 42 by means of a switching transistor 24. A control voltage having the polarity indicated is connected between terminals 17, 18 and when the Zener point of the diode 20 is reached the base of the transistor 12 is driven positive. The collector current rises and induces in the coil 22, coupled to coil 19, a potential having the polarity indicated and the base potential rises still further cutting off the Zener diode and increasing the collector current still further. Upon reaching saturation, the collector current starts to decrease driving the base negative and the Zener diode conducts again allowing capacitor 21 to discharge until the base again becomes positive and the cycle repeats. The oscillator output is rectified by diode 29 and the resulting D.C. potential applied to the base of the transistor 24, thus placing it in a conductive condition and providing a low impedance path between terminals 31 and 32 of the rectifier bridge. If the circuit to be controlled, which may be A.C. or D.C., is connected between terminals 41 and 42 current will thus flow from terminal 41 through transistor 24 to terminal 42 as long as the control potential maintains the circuit 10 in oscillation. In a modification (Fig. 2, not shown) a second transistor stage is added to the switching circuit to give greater power gain.

Abstract: 972,378. Electric motors. J. RITZ. May 4, 1962 [May 4, 1961], No. 17156/62. Heading H2A. In a canned electric motor each end of the stator cavity is sealed by ring 5, made of elastic material, which is compressed between annular plate 3, having flanges 3a attached (by soldering) to gap tube 1, and compression plate 6. Axial movement of the annular plate is prevented by spring clip 4 and the depressing pressure applied to the sealing ring by screws 7 having on the plate 6 from plate 8 which is retained by clip 9. Lead-in holes for supply cable 11 are made in all the plates and when ring 5 is compressed it seals against the outside of the cable. The anchor plate 8 may be of any shape, but preferably it is constructed as two half plates, Fig. 3 (not shown), and can be used to support the motor bearings. A similar end seal construction may be used when the stator cavity is filled with casting compound, the filling tube being removed when the compound has solidified, Figs. 4, 5 (not shown). In another modification when the annular plate at one end is used as a feed head, during casting, an 0-ring is tightened into the gap between the plate and the shell by the bevel edge of the compression plate, Figs. 6, 7 (not shown). A further modification, Figs. 8, 9 (not shown), shows a sealing ring sandwiched between two annular plates which may be drawn together to compress the elastic ring which is forced into an annular groove in the shell to locate the end assembly.

Title: Reactive dyes of the anthraquinone series
Inventor: SCHOENAUER WOLFGANG
IPC: C09B62/467
Filed: 1961-05-12
Abstract: The invention comprises water-soluble reactive dyes of the aminoanthraquinone series which contain at least one group of the formula -CH2-NH-OC-C(Ha1)=CH2 wherein Ha1 is a chlorine or bromine atom the said group being bound to an aryl group of the dye molecule. The dyes are prepared by reacting anthraquinone derivatives containing exchangeable hydrogen atoms with an a -halogenoacrylic acid amide and symmetrical dihalogenodimethyl ether and sulphonating the products if they are not water-soluble.  The reaction may be carried out in one step but preferably an intermediate is formed by reaction of the a -halogenoacrylic acid amide and the ether and this intermediate is reacted with the anthraquinone.  The reaction is preferably carried out in sulphuric acid medium so that sulphonated products are obtained.  The dyes may be used to dye wool, silk, synthetic polyamides and leather in blue and green shades and may also be used to dye cellulose fibres in the presence of an acid-binding agent.  In Example (1) an a -chloroacrylamide is dissolved in concentrated sulphuric acid, dichlorodimethyl ether is added dropwise and the mixture stirred for 16 hours then run into a solution of 1,4-dimesidino-anthraquinone in sulphuric acid. The mixture is stirred for 24 hours, run into ice, the precipitate filtered and further sulphonated with oleum to give a blue dye. Further examples are specified.
