Abstract: 877,207. Releasable fasteners. MAIN, J. A. Jan. 31, 1958 [Feb. 1, 1957], No. 3513/57. Class 44. A jewellery snap fastener of the tongue and socket type in which a resilient tongue 11 is received in and snap engages an end of a box-like socket 12 and which has manually operable means 13 on the tongue for releasing the engagement, is provided with a projection 30 on the resilient tongue for co-operation with a locking latch 24 which is associated with a manually operable locking member 18, said member being mounted for pivotal movement into locking and unlocking positions and transmitting angular movement to the locking latch which is in the socket during such movement whereby the tongue can be locked or unlocked. The locking latch is also the pivot pin for the member 18 and is provided with a groove 27 which in the unlocking position of the member 18 registers with the projection 30 on the tongue to permit the tongue to be withdrawn from the socket; when the member 18 is in the locking position in which it rests upon the top of the socket the position of the pin is such that the tongue cannot be withdrawn, the projection 30 engaging the periphery of the pin.

Abstract: 243,936. Bundy, H. W. Feb. 10, 1925. Tubes. - In soldering and solder coating multiple ply, butt lock seamed and other tubes, the tube passes through a conduit, which is contained in a solder tank and is provided with a valved aperture through which the solder passes on to the tubes. A metal strip a passes through a fluxing bath b and is then converted into a tube by rolls c, the tube then passing through a conduit d which passes through a gas-heated tank e containing molten solder. The solder passes through an aperture in the conduit controlled by a needle valve i so that the flow of solder is regulated so as to solder and coat the tube without substantial waste. A drip pan k serves to catch any surplus solder. The tube then passes through dies m for scraping off excess of solder and for sizing the tube and then passes through a cooling tube n supplied with water from a pump p.

Abstract: 593,402. Control of two motors. ENGLISH ELECTRIC CO., Ltd., and MARDIS, P. L. March 20, 1941, No. 3826. [Class 38(iii)] Motors 5, 6 driving for example endlesstracks of a vehicle, are supplied from individual generators 1, 2 driven by a common prime mover e.g. a diesel engine, and are controlled for varying their relative speeds by decreasing simultaneously the excitation of one generator and of the other motor. To slow down motor 5, switches 21 are successively opened to reduce the voltage of the exciter 3 supplying generator field 1b and motor field 6b, switch 13 if open is either closed or shorted to give strong excitation of motor field 5b, switch 20 is closed to give maximum voltage on exciter 4 and after all switches 21 are opened, switch 24 is opened to completely de-excite the exciter 3. This system of control is applicable to the system described in Specification 592,299.

Patent GB-799502-A (GB)
Title: Preparation of ketals
Filed: 1957-02-05
Abstract: Lower ketals are prepared by contacting a mixture of methanol or ethanol and a saturated aliphatic ketone having from 3 to 5 carbon atoms with a cation-exchange resin in the acid state at a temperature of - 40 DEG  to 25 DEG  C. for a length of time sufficient to obtain substantially equilibrium conditions and recovering the ketal.  The alcohol is preferably used in excess, for example 4-6 or more mols. per mol. of ketone.  Maximum conversion is obtained at the lower temperatures and the catalyst should be removed at the low reaction temperature to prevent the reverse reaction occurring during storage or recovery of the ketal.  Preferably, after removal of the cation-exchange resin, the reaction mixture is treated to remove residual traces of the resin and any hydrogen ions present by means of an anion-exchange resin or a basic compound such as sodium, potassium or calcium hydroxide.  The ketal may be isolated from the reaction mixture by the method described in Specification 799,501. In experiments: (A) a 4.55 to 1 molar mixture of methanol and acetone is passed down a column of acidified sulphonicacid type cation-exchange resin disclosed in U.S.A. Specification 2,500,149 at temperatures ranging from - 60 DEG  to - 30 DEG  C. and a graph is given showing the conversion of acetone to 2,2-dimethoxy propane against temperature (conversion is zero at 55-60 DEG  C.); (B) similar methanol-acetone mixtures are reacted at - 30 DEG  C. as in (A), in the first case without taking special care to avoid agitation of the resin bed, in a second case taking such care and in a third using a column containing the same cationexchange resin resting on a layer of a quaternary ammonium hydroxide anion-exchange resin of the kind described in Specification 679,850, [Group IV (a)], and only the ketal effluents obtained in the second pair of methods are stable for long periods at room temperature.  Examples describe (1) the reaction of methanol (4.3 mols.) with methyl ethyl ketone at - 30 DEG  C. as in (A), the effluent being extracted with 13 per cent aqueous caustic soda and the residue is diluted with petroleum ether, dried and distilled to recover the ketal; (2) ethanol (2.54 mols.) and acetone are used as in (1); (3) methanol and acetone are used in the method of (1) at - 34 DEG  C.  Other suitable cation-exchangers and anion-exchangers are those described in Specification 577,707, [Group IV], and U.S.A. Specification 2,597,438 and in Specification 654,706, [Group IV (a)], and U.S.A. Specifications 2,341,907, 2,597,440 and 2,597,494 respectively.

Patent GB-649959-A (GB)
Title: Improvements relating to radio tuning circuits
IPC: H03J7/30
Filed: 1948-05-25
Abstract: 649,959. Automatic tuning. GENERAL MOTORS CORPORATION. May 25, 1948, No. 14069. Convention date, July 5, 1947. [Class 40 (v)] A radio receiver comprises a power-operated tuning device by which a frequency band is repetitively scanned, a detector in which a signal voltage is generated, and a pair of interconnected electronic tubes, one of which is normally conductive and the other non- conductive, the arrangement being such that a generated signal voltage renders the first tube non-conductive and the second tube conductive to operate a switch to stop the power of the tuning device. In Fig. 2 a negative voltage from the A.V.C. diode 2 is fed through resistance 8 and battery 10 to render valve 16 non-conductive on receipt of a signal. This reduces the voltage drop across anode resistance 24 and allows valve 22 to become conductive and operate relay 30 to the position shown. This breaks the tuning motor circuit at 50, 54 and completes a hold-on circuit at 56. To change to another station, switch 64 is momentarily moved on to contact 66 to de-energize relay 30 and break the hold-on circuit. The tuning motor then resumes scanning until a signal sufficient to cut-off valve 16 is received. In a modification (Fig. 3, not shown), the holdon circuit is completed through a valve which becomes conductive only after a time delay. Thus on a weak signal, if the stopping control voltage does not persist long enough for the hold-on valve to become conducting, the relay falls off and scanning is resumed. The relay also has a contact which, during tuning, applies a muting bias to one of the audio stages. In a further modification, the auxiliary hold-on valve is replaced by a delay condenser between the two control valves.
Patent GB-466910-A (GB)
Title: Improvements in or relating to the treatment of gases containing organic vapours
IPC: B01D53/00
Filed: 1936-02-11
Abstract: <PICT:0466910/III/1> Solvent vapours are recovered from gases by absorbing them in an alkyl ester of phosphoric acid or alternatively, in phosphoric p  acid esterified by at least one aliphatic alcohol radical and at least one phenol radical.  For example, dibutyl phenyl phosphate, phosphoric acid esters of glycol ethers, or trimethyl, triethyl, or tripropyl phosphate may be used.  If the esters used are solid at normal temperatures they may be dissolved in diethyl phthalate, dibutyl tartrate, triacetin, or ortho- or metatoluene ethyl sulphonamide.  In the apparatus shown, fabric treated with solutions in a chamber 1 is dried by air circulation in chamber 4. The air and solvent vapour then passes through pipe 8 to a tower 12 wherein the solvent vapours are absorbed in the phosphoric ester. The ester then passes through a heat exchanger 21 to a still 23 in which the solvent is driven off.  The ester then passes through exchanger 21, a cooler 26, and a reservoir 16 back to the tower 12. If a mixture of solvents is employed, a fractionating column 29 is provided to separate the vapours into two fractions which are condensed and collected in tanks 32 and 37.
