Filed: 1924-11-20
Abstract: 236,802. Baxter, C. Nov. 20, 1924. Spray carburettors.-The invention consists in an auxiliary device for attachment to existing carburettors to improve their working both as regards the normal fuel supply and during slow running. In its application to a simple type of carburettor having a single nozzle 13, Fig. 1, supplied from a float chamber 10, the device comprises a fuel chamber 1 open to the atmosphere at 2 and connected to the float chamber bv a pipe 11 controlled by a needle valve 3. This chamber is arranged to supply through a conduit 14 an additional nozzle 9 in the mixing chamber and, through a conduit 27, a slow running orifice 8 in the vicinity of the throttle valve 15. The orifice 4 of the auxiliary nozzle is at a higher level than the orifice 5 of the slow running conduit, to ensure that the latter is always covered with fuel and ready for action. The conduit 27 has a variable air inlet 6 and a throttle valve 7, and the fuel orifice 23 thereto may be adjustable. The application of the invention to the type of carburettor usually fitted to Ford cars is shown in Fig. 2. In this type the main nozzle terminates in a cup 13 adapted to hold a reserve of fuel and from which fuel for slow running is drawn through a pipe 16, orifice 17 and conduit 18, 22. An orifice 19 usually plugged bv a screw is utilized to connect the conduit 18. 22 to the conduit 27 of the auxiliarv device described above. The auxiliary nozzle 9 is connected to the chamber 1 by a pipe 14 passing in an airtight manner through the cover of the mixing chamber. The needle valve 24 for controlling the main nozzle is bored axially to permit of the passage of air to assist in dislodging some of the fuel from the cup into the main air stream to form a mixture for use until the nozzle 9 comes into action. By closing the orifice 23 and opening the air orifice 6, the slow running mixture from the pipe 16 may be diluted. The pipe 11 is connected to the float chamber by utilizing the existing drain plug orifice. As modifications, (1) the drilled needle valve 24 may be replaced either by a tube passing through the carburettor wall and open to the atmosphere, or opening merely into the spray chamber, (2) the slow running ducts may be used in place of the pipe 14 when conduit 27 discharges between the throttle 15 and the engine, (3) the chamber 1 may be replaced by two chambers connected at the bottom by a short duct and (4) the main and compensating nozzles. may be in one body.

Title: Improvements in or relating to the recording and reproducing of sound
IPC: G11B7/00
Filed: 1930-06-06
Abstract: 360,903. Recording sound optically. GRAMOPHONE CO., Ltd., Hayes, Middlesex, CONDLIFFE, G. E., Thorncombe, Fulmer Road, Gerrards Cross, Buckinghamshire, and BROWNE, C. O., 3, Freeland Road, Ealing Common, London. June 6, 1930, No. 27838/31. Divided on 358,993. [Class 40 (ii).] Optical sound records of the variable width type on opaque or transparent carriers and having a minimum of parasitic noise effect are so recorded that the crests and troughs of the recorded wave lie on longitudinal lines whose departure from straight lines is less than the changes in amplitude of the recorded sound and the transparency of the transparent part of the record varies in accordance with the changes in amplitude of the sound recorded, this variation of transparency being produced either at the recording stage or subsequently when making a positive from a negative. Fig. 1 shows a record in which the sound is recorded at constant and maximum amplitude, produced for example by the use of a microphone or microphones whose sensitivity is controlled in known manner so that the electrical impulses generated in them by the sound are all of approximately the same intensity. The transparent part of this record is made to vary in transparency in accordance with the variations in amplitude of the recorded sound, and this is effected either during the recording of the wavy line with constant and maximum amplitude, or in a printing operation from such wavy line record, by the adjustment manually or automatically of an optical wedge in the path or the recording light or of a printing light. Fig. 2 shows an arrangement for printing the desired record 13 from a wavy line record 9 of constant and maximum amplitude but whose transparent portions are not modulated. Light from a source 15 directed through a lens 16 and gate 14 prints the wavy line record 9 on to the carrier 13, and the transparent parts are modulated by a movable optical wedge 20 in the path of light from a source 18 directed through a lens 19, the wedge 20 and a gate 17 which need not be opposite to the gate 14. The movements of the wedge to effect modulation may be effected manually by the aid of a monitoring beam directed through the records at a point K and influencing a loud-speaker, and by providing the loud-speaker with a rheostat operatively connected with the wedge; adjustment of the rheostat to vary the speaker output as required will automatically adjust the wedge. The wedge may be calibrated.

Abstract: 1,197,544. Preparation of triglycidyl iso- Cyanurate. CIBA Ltd. 12 June, 1968 [13 June, 1967], No. 28007/68. Heading C2C. Triglycidyl isocyanurate is prepared by condensation of cyanuric acid with epichlorohydrin in the presence of a tertiary amine, a quaternary ammonium base or a quaternary ammonium salt as catalyst, the epichlorohydrin being used at a rate of 2-10 mols per equivalent of active H atom of cyanuric acid, to form the corresponding mono-, di- or tri-(3-chloro-2- hydroxypropyl)-isocyanurate followed by conversion of the tri-compound into triglycidyl isocyanurate by removal of hydrogen halide. The first stage of the reaction is carried out at a temperature of 60-165 C., and the cyanuric acid is converted almost quantitatively into tri-(3- chloro - 2 - hydroxy - propyl) - isocyanurate by an additive reaction with epichlorohydrin, a part of the initially formed 3-chloro-2-hydroxypropyl groups being transepoxidized with the excess epichlorohydrin to glycidyl groups and an equivalent proportion of epichlorohydrin adding on to the hydrogen chloride liberated from the 3-chloro-2-hydroxypropyl groups to form glycerine dichlorohydrin. When the end point of the reaction is reached, the 3-chloro-2- hydroxypropyl isocyanurate and glycerine dichlorohydrin in the reaction mixture are dehalogenated to triglycidyl isocyanurate and epichlorohydrin respectively by dropwise addition of 5-40% stoichiometric excess of concentrated aqueous alkali hydroxide, and at the same time the water of reaction formed and the water added in the form of alkali solution are distilled off as an azeotrope with epichlorohydrin at the same rate as they are formed and added respectively. After working up the reaction mixture the catalyst is washed out or extracted from the crude triglycidyl isocyanurate. During the first step of the reaction the catalyst may be present in a concentration of 0À01-5% w/w., with respect to the total weight of the components and further amounts of catalyst may be added during the removal of hydrogen halide. The removal of hydrogen halide may be carried out within the boiling range of the reaction mixture or under reduced pressure at 50-80 C. After the crude reaction product is washed with water to remove the catalyst, the excess regenerated epichlorohydrin may be distilled off and the epichlorohydrin distilled azeotropically with water may be recycled to the reaction mixture.
