Title: Improvements in or relating to non-free-tripping overload circuit breakers
IPC: H01H71/74
Filed: 1945-05-10
Abstract: 612,110. Automatic circuit-breakers; tumbler switches; thermal switches. IGRANIC ELECTRIC CO., Ltd. May 10, 1945, No. 11720. Convention date, May 10, 1944. [Class 38 (v)] In a non-trip-free circuit-breaker provided with a bimetal overload release, the bimetallic element is protected against burning out should the circuitbreaker be held closed, by an auxiliary switch which closes its contacts to short out the bimetallic element and its associated heating coil. A lever 16 actuates a contact arm 46 which rocks on a forked conductive pivot 44 and completes a circuit between terminals 100 comprising a strip 107, 105, 42, 44, the arm 46, contacts 47, 37, strips 36, 35 and 80, 79, a bimetal strip 65, a conical heater coil 102 and a strip 96, 97. The lever 16 is initially biassed to the " off " position, shown dotted in the Figure, by the enlarged end 31 of a slidable insulating plunger 30, urged by a spring 33. As it slides in a recess 29 the plunger 30 causes a lug 58 on a metal plate 54 to traverse a slot 61 in an insulating plate 60, which is interposed between upper and lower moulded insulating members 11, 12. A lug 63 welded to the bimetal strip 65 normally latches the lug 58 when the lever 16 is moved to the " on " position, retaining it there when the operating force is removed until an overload current heats the strip 65 and deflects it downwards. As the lugs 63, 58 unlatch, the plunger 30 moves the lever 16 to the " off " position. If the lever 16 is held " on " during a sustained overload, an arm 82, rigidly joined to the strip 65 at 81, continues to move downwards until contacts 90, 91 close, short-circuiting and thus protecting the strip 65 and the coil 102. The ends of the strip 65 are pressed upwards by springs 86, 75 against a free pin 83 and the enlarged end 71 of a threaded member 73. An internally-threaded rivet 93 with a rectangular head 94 secures the strip 96 to the member 12 and carries a stud 92 on which the contact 91 is mounted. The sensitivity of the overload protection is varied by a factory adjustment of the members 73, 92 and the spaces 77, 99 sealed. The lever 16 is pivoted at 17 between a metal plate 10 and the member 11, the parts 10, 11, 12 being held together by four long rivets. The circuit-breaker is mountable as a unit behind a panel by screws entering two resilient locking nuts 115. An insulating cup 123 is a push fit over the strips 35, 80 or is stuck on to the member 12. The contacts 37, 47, 90, 91 may be of silver. The Specification as open to inspection under Sect. 91 describes and illustrates a circuitbreaker having no auxiliary switch to protect the bimetallic element which is without a heating coil, and also refers to U.S.A. Specification 2,342,945. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to electric interrupter switches
IPC: H01H61/06
Filed: 1951-05-21
Abstract: 711,351. Thermal switches; snap-action switches. MIDGLEY, A. H., and MIDGLEY, A. M. April 21, 1952 [May 21, 1951; Jan. 25, 1952], Nos. 11829/51 and 2074/52. Class 38(5) A thermal "flasher" or switch has a sheet of spring material 9 with a longitudinal slot 9c forming two strips 9a, 9b, the length of the strip 9b being increased in relation to that of the strip 9a. The latter strip is supported between terminal extension members 5, 6 with interposed insulation 8, the member 6 carrying an adjusting screw 12 and the member 5 carrying a fixed contact 5a which co-operates with a contact centrally disposed on the strip 9b. One end of the sheet 9 is bent so as to normally bow the strip 9b towards the fixed contact 5a, but a tensioned wire 13 connected between the member 5 and the other end of the sheet 9 causes the strip 9b to abut the screw 12. When the wire is heated by the current flowing through it, it relaxes it's tension and the strip 9b moves its contact with a snap-action into engagement with the fixed contact. The wire is then short-circuited and cools re-opening the contacts and the cycle is repeated. The sheet 9 may be provided with a tongue 9d, as shown, carrying a further contact which co-operates with a contact carried on a terminal extension member 15, these additional contacts being adapted to control a circuit (e.g. of a warning light) separate from that through the wire 13, contact 5a and strip 9b (e.g. that of a flashing turning signal light on a vehicle). The strip 9a need not be a continuous strip.

IPC: G09G1/04
Filed: 1970-03-12
Abstract: 1303181 Cathode-ray tube displays COMPUTER OPTICS Inc 12 March 1970 [12 March 1969] 11851/70 Heading H4T Each of the three beams of a display cathoderay tube (Fig. 2) is intensity modulated by character data information as they are scanned in an interlaced line raster by a common scanning means 4 to produce blocks of text information (Fig. 1) each comprising three text lines each composed of twenty horizontal line traces. This is achieved by superimposing on the vertical sweep an auxiliary sweep (linear ramp) termed a " diddle " sweep the period of which corresponds to the time required to scan ten horizontal traces (see Figs. 3A, 3B, 3C) so that the line spacing is compressed during the scanning of the traces forming each text line and is increased between the text lines. By this means the size of the characters is reduced without altering character definition and the number of characters displayed (by each gun) may therefore be increased without increasing the operating frequency or bandwidth of the system. Fig. 6, shows the general scheme in which data specifying the characters to be produced by each gun A, B, C, and derived from a circulating memory 30 is fed to respective registers 31, 32, 33 during the tracing of alternate text blocks and to respective registers 34, 35, 36 during the tracing of intervening text blocks the loaded register being read out into a character generator 70 as the other register is being loaded. The character generator produces beam bright-up signals which are fed via respective gates 71, 72, 73 to the respective control grids of the guns A, B, C the gates being switched to produce twenty-four horizontal increments for each character position selected adjacent ones of which pass the bright-up signals so that the characters are formed as shown in Fig. 4 in respect of the character " O " by the bright-up of certain of the increments X1 to X24 during the odd and even horizontal traces Y1 to Y16. (The upper sixteen traces are used in the formation of upper case letters and numerals and the lower four lines are used to form the stems of lower case letters.) The character data comprises six bit words per character and the registers 31 to 36 each have 128 stages through which the data is circulated so that six bit words for each of 100 characters (forming one text line, 28 character periods being utilized for horizontal retrace) are successively applied to the character generator 70 in parallel form. The system operates at conventional television line and field scanning raster under the control of a clock 20. A portion of the character generator used in the formation of the capital letter " O " is described with reference to Fig. 7, not shown.

Title: Improvements in or relating to the generation of sound waves
IPC: G10H3/06
Filed: 1941-09-16
Abstract: 567,491. Electrically vibrated musical instruments. INTERNATIONAL POLAROID CORPORATION. Sept. 16, 1941, No. 11863. Convention date, Sept. 16, 1940. Drawings to Specification. [Class 88 (ii)] [Also in Groups XX and XL] Musical tones are generated by the production of sinusoidal fluctuations in the intensity of a beam of light by means of relative rotation between light polarizing elements positioned in the path of said beam, and conversion of said light fluctuations into sound oscillations by a photo-electric cell influenced by the light and connected to a loud-speaker or like sound-producing device. The sound may be of sub-audible, audible or super-audible frequency. According to the number and arrangement and relative speed of the polarizing elements any fundamental tone with or without harmonics may be produced or one or more harmonics only. Bi-refringent or half-wave retardation elements may be used in addition to the polarizing elements. Groups of such devices may be provided with a common light source, or each with a light source of its own, and the fluctuations produced by the several groups may be combined optically. Shutters may be provided in the several optical beams. The intensity of the tone produced may be varied by varying the quantity of the light beam falling on the photo-sensitive or thermosensitive device or by varying the energization of the light source. Many arrangements and details are described. Specification 17156/10, [Class 40 (v)], is referred to. Reference has been directed by the Comptroller to Specifcation 332,318, [Class 97 (i)].

Patent GB-883228-A (GB)
Title: Manufacture of oct-3,5-dien-2,7-dione and oct-4-en-2,7-dione from oct-7-ol-3,5-dien-1-yne
IPC: C07C45/26
Filed: 1958-04-15
Abstract: Oct-3,5-dien-2,7-dione is prepared by oxidising oct-7-ol-3,5-dien-1-yne to oct-7-one-3,5-dien-1-yne and hydrating the latter to form the desired dienic dione or by hydrating the oct-7-ol-3,5-diene-1-yne to oct-7-ol-3,5-dien-2-one and oxidising the latter to the dienic dione.  Both oxidations of the >CH.OH group to a carbonyl group may be effected with a slurry of manganese dioxide in an inert organic solvent; with tertiary butyl chromate; or with an aluminium tertiary alkoxide in the presence of a hydrogen acceptor. The hydrations of the acetylenic bond to form a carbonyl group may be effected in an aqueous methanol or acetone or other aqueous solvent system which may contain a hydration catalyst such as sulphuric, phosphoric or formic acid in combination with a mercury compound such as mercuric oxide or p  sulphate, or which may contain perchloric acid or BF3, alone or with a mercury compound.  The resulting oct-dienic dione may be converted into oct-4-en-2,7-dione by partial hydrogenation by treatment, for example, with a metal-acid combination such as zinc and acetic acid, in an amine solvent such as pyridine.  The oct-7-ol-3,5-dien-1-yne starting material may be prepared by ethylynating sorbaldehyde and subjecting the resulting oct-4,6-dien-3-ol-1-yne to an alkylic rearrangement.  The ethylynation may be effected by reacting the sorbaldehyde with a Grignard reactant CH­C.MgX or with the acetylide of a basic metal such as lithium, sodium, potassium or calcium, if desired in a solvent, and hydrolysing the resulting complex, e.g. with aqueous brine or NH4Cl solution.  The basic metal acetylide may be preformed or may be formed in situ by using liquid ammonia as a solvent and adding the metal and then acetylene thereto.  The alkylic rearrangement may be effected by treating with an aqueous solution of sulphuric, hydrochloric, phosphoric, formic, acetic, trichloracetic or other acid, preferably in the presence of an anti-oxidant such as hydroquinone, butylated hydroxy anisole or butylated hydroxytoluene, under an inert atmosphere.  Examples describe the synthesis of oct-4-en-2,7-dione from sorbaldehyde by both multi-stage processes described above, the intermediates being isolated and purified after each stage.

Abstract: 273,857. Hutchin, S. May 10, 1926. Bottling.-Relates to bottling machines of the rotary suction or vacuum type and consists ir means for controlling the flow of the liquid tc bottles comprising a filling valve and an inter. ceptor. The valve 29, Fig. 2, communicates with the liquid supply tank and is normally held on its seating by a compression spring 31 and guided by vanes 30. A plate member 35 having peripheral slots engaging guides 34 prevents the valve from rotating. Under the valve a combined filling and vacuum nozzle projects downwardly and com prises a tube 42 which communicates with the interior of the valve casing and a smaller tube 44 communicating with the vacuum pipe 23. The wall of the tube 42 is cut away at 46 to prevent the retention of liquid in the nozzle during bottling. The compression of the spring 31 is varied by adjusting a cap 32 having an aperture 47 for engagement by a tool inserted in the tube 42. Deformable washers 48 seal the bottle-neck during filling. The interceptor, Fig. 3, comprises a glass vessel 49 having a cover 51 communicating bv the pipe 19 with a distribution valve and by the pipe 23 with the filling valve. When the vessel 49 is filled a float-operated valve 57 closes the aperture 58<1> leading to the vacuum pump through the distribution valve and the liquid therein is returned to the supply tank below through a trap 60. In operation, when the distribution valve is rotated to a position to subject a bottle to vacuum through the intercepter and pipe 23 the valve 29 is forced off its seating, but when the vacuum is interrupted the valve is closed by the action of the spring 31. If a bottle is overfilled before the vacuum is destroyed, the liquid ascends the pipe 23 to the intercepter and automatically cuts off the vacuum.
