Title: Improvements in or relating to testing methods in telephone exchanges
IPC: H04M3/28
Filed: 1930-10-23
Abstract: 361,079. Automatic exchange systems. COVENTRY AUTOMATIC TELEPHONES, Ltd. and CHUBB, A. A., of General Electric Co., Stoke, Coventry. Oct. 23, 1930, No. 31841. [Class 40 (iv).] For testing transmission bridges in telephone systems, alternating current substantially of voice frequency generated by a buzzer or vibrating relay is transmitted through the bridge and detected by a receiving relay having a reed responsive to the frequency of the transmitted currents. As shown in the Figure, the condenser 10 is tested by the transmission of current generated by the vibrator 4 to operate a relay 12 the tuned reed 13 of which operates a relay 14 which lights a lamp 17. If the condenser is disconnected the relay 12 remains inoperative and further in the event of a shortcircuit the relay 12 is continuously energized over the winding of relay 9. The transmitting vibrator is operated by a key 1 which when depressed causes energization of winding 2 to attract the reed which breaks its contacts 4 and thereby causes energization of winding 3 in the reverse direction to effect release of the reed and repetition of the cycle. Relay 14 may be utilized to step a switch or operate relays in an automatic tester or routiner. On completion of the test on condenser 10, condenser 11 may be tested in like manner. In modifications, the test current may be applied to and received from the bridge through transformers in order to test both sides of the bridge in series or through the mid points of chokes which facilitate testing both sides in parallel. The test may also be applied to bridges of the type supplying battery in both directions through the windings of a repeating coil or to bridges having- relays similar to 9 on each side of the condensers. In the latter case in order to avoid incorrect operation of the relay 12 when the condenser is disconnected, a resistance is provided to reduce the transformer action through the relays.

Title: Improvements in and relating to welding apparatus
IPC: B23K11/31
Filed: 1933-11-20
Abstract: 415,913. Electric welding. BRIGGS MANUFACTURING CO., 11631, Mack Avenue, Detroit, Michigan, U.S.A.-(Assignees of Platz, H. T. ; 11631, Mack Avenue, Detroit, Michigan, U.S.A.) Nov. 20, 1933, No. 32342. Convention date, Sept. 20. Addition to 402,551. [Class 83 (iv).] In an electric welding device in which the movement of the electrodes to engage the work controls fluid pressure means which close the electric circuit to the electrodes, as described in the parent Specification, means operated by fluid pressure are provided for automatically moving the electrodes out of engagement with the work after a predetermined time interval. A movable electrode 12 of a pair of electrodes 11, 12 is carried by a sleeve 16 slidable against the pressure of a spring 19 in an outer sleeve 17 to accommodate different thickness of workpieces. The sleeves 16, 17 form part of a piston assembly 14 slidable in a cylinder 15 and normally maintained by a spring 25 with the electrodes 11, 12 separated. Fluid pressure is introduced through a pipe 26 past a piston valve 27 to the cylinder 15 to displace the piston 14 into the operative position. A spring 31 maintains the piston valve 27 in the closed position until it is displaced inwardly to the position shown by a trigger 32. The fluid pressure then keeps it in its innermost position until pressure fluid, which has leaked from the cylinder 15 through a port 37, uncovered as the piston approaches the end of its stroke, and an adjustable passage 36 to a pressure accumulating chamber 35 in the housing of the cylinder 15, and passed from the chamber 35 through a passage 40 to the inner face of the piston 30 adds sufficient power to the spring 31 to force the piston to the closing position. The electrodes 11, 12 are connected by cables 54, Fig. 4, to fixed contacts 53 in a casing 50. To close the electric circuit, a bridge piece 55 carried by a sleeve 58 slidable in a bushing 59 is thrust across the contacts by fluid pressure supplied from the chamber 15 to a switch chamber 52 in the casing 50, the pressure acting in opposition to a spring 62. The action is delayed until the electrodes are in their operative position by disposing a metering valve in the passage 65 connecting the chambers 15, 52. The pressure building up in the accumulating chamber 35 is communicated to a chamber 66 at the other end of the bridge piece assembly and eventually enables the spring 62 to open the circuit. As the piston valve 27 reaches the closing position, it uncovers a port 41 open to the atmosphere and the chambers 15, 35 discharge therethrough.

Title: An improved method of preparing rubber vehicle tires for vulcanization
IPC: B29D30/06
Filed: 1931-11-23
Abstract: The use of air-bags in the vulcanization of tyres is obviated by the application to the surfaces to be subjected to gas pressure, of a layer of a gas-impermeable composition.  A suitable composition is 22,9 parts of gelatine, 35,1 parts of water, 7,8 parts of phenol, 18,9 parts of alcohol, and 15,3 parts of glycerol, which is spread as a thin film and allowed to dry before vulcanization is proceeded with.  Other proteinous matter such as glue may replace the gelatine, and other softeners, such as polyglycerol, may be employed.
Patent GB-618197-A (GB)
Title: Improvements in or relating to shaping cellular products made of artificial resins
IPC: C08J9/36
Filed: 1946-11-01
Abstract: A mass of solvent-sensitive porous thermosetting resin is softened by treatment with steam and then deformed to make a shaped article. Solventsensitive thermosetting resin is defined as thermosetting resin which does not soften on heating in air but swells when immersed in methyl ethyl ketone.  The deformation should be effected gradually: e.g. a porous resin sheet is bent from flat form to semi-cylindrical form by means of a sheet of porous flexible canvas which is superposed on the resin sheet and weighted at its edges, the two sheets being supported on a semi-cylindrical curved surface and superheated steam at 160 DEG C. and atmospheric pressure being admitted to the vessel in which the deformation is taking place.  The resin sheet bends gradually under the action of the weighted canvas. Alternatively, a resin sheet may be corrugated or indented between platens in a vessel containing steam, the platens preferably being perforated to allow access of steam to the sheet.  The resin may be the porous phenol-formal-dehyde resin made according to Specification 571,284, [Group IV], or may be hydrophilic resin, i.e. normally solid thermosetting resin which is miscible with water at an intermediate stage of condensation.  The porous resin may be made by forming a flowable mix of an aqueous incompletely-condensed resin syrup, an acid hardening agent and a substance that reacts with the hardening agent to form a gas, introducing the mix into a mould and allowing condensation to proceed without external application of heat (see Specification 571,284).  Specification 586,199, [Group IV], also is referred to.

Abstract: 844,449. Protective cut-out arrangements. FOSTER TRANSFORMERS Ltd., and JENNINGS, R. E. Oct. 25, 1957 [Oct.25, 1956], No. 32531/56. Class 38 (5). In a safety earthing arrangement, the contacts 1 of a contactor are closed and normally maintained closed against the action of opening springs by an operating coil 2 connected in series with one winding of a transformer 7 which has another winding normally short-circuited by independent earth leads 8, 9 to the protected equipment 3. In the event of failure of either lead 8 or 9, the short-circuit is removed from the transformer which then imposes a high impedance in series with the coil 2 causing the contactor to open. Should the frame of the equipment rise in potential above neutral, due to earth leakage, a relay 11 is energized and opens its contacts 10 to open the contactor.

Title: Improvements in and relating to electric lamps
IPC: H01J5/62
Filed: 1952-12-23
Abstract: 738,669. Capping electric lamps. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 23. 1952 [Dec. 26,1951], No. 32624/52. Class 39 (2). [Also in Group XXII] Electrical connection between a leading-in wire and a lamp cap, e.g. an aluminium cap, is obtained without the use of solder by locating a part of the leading-in wire 5, Fig. 2, between the outside wall of the neck of the bulb and a tightly fitting cylindrical shell portion of a cap 7 and forming a linear inward indentation 18 in the shell near its edge and disposed transversely to the said part of the leading-in wire, so that the wire is embedded in the ridge thus formed. The operation is performed sub. sequent to the attachment of the cap to the bulb by cement disposed within the cap as an annular ring, preferably at a slight distance inwardly from the edge of the cap, in order that the metal in that region may be left uncoated by cement. The indenting may be effected by swinging a pointed tool, e.g. a sharp-edged roller 41, Fig. 4, along the circumference of the shell during the indexing movement of the lamp between two work stations of a lamp-making machine of known type, the cap being gripped between a pair of holding jaws of the machine and the lamp positioned so that the part of the leading-in wire that is clamped beneath the cylindrical part of the cap is on the side nearest the tool. As shown, a sharp-edged roller 41 is mounted on a pivot 42 within the bifurcated end portion of a plunger 35 which is pressed forwardly within a channel 36 in a bracket 33 by a spring 37. The compression of the spring is adjustable by a screw 38, and the movement of the plunger is limited by a pin 39 which rides within a slot 40. Specification 247,923, [Class 39 (ii)], is referred to.

Title: Article handling methods and apparatus
IPC: B65G49/06
Filed: 1968-07-09
Abstract: 1,240,501. Flotation conveyers. GLAVERBEL. 9 July, 1968 [12 July, 1967], No. 32642/68. Heading B8A. [Also in Divisions C1 and F2] Articles, such as glass sheets, are supported, at least partially, by gas jets which discharge upwardly towards the articles from orifices which are displaced horizontally or with a horizontal component of motion. In the embodiment shown in plan view in Fig. 1, the upper run of an endless belt having transverse rows of slots 12 passes over the upper face of a plenum chamber 1 which is formed with longitudinal slots 7. In operation, the article is supported by gas jets passing through the orifices 14 formed by the intersection of slots 7, 12, the orifices moving at the same speed as the upper run of the belt. In a modification, Figs. 3, 4 (not shown), the endless belt is mounted within the plenum chamber, with the upper run of the belt adjacent the top wall of the chamber. For handling curved sheets, the top of the chamber is of arcuate cross-section and the belt rollers have curved generatrices. In a second embodiment, Fig. 6, the sheet 43 is supported partially by rollers 25 and partially by gas issuing from radial apertures 29 in hollow rollers 26 connected to a plenum chamber. In operation, the rollers 26 are rotated in the direction 42 corresponding to the required direction of movement 44 of the sheet 43. The driving effect of the gas jets can be modified by moving rollers in which the apertures are inclined to the radii or by deflecting the jets on one side of the rollers by vanes 109, or by masking the apertures on one side by screens 110. The sides of the sheet may be guided by edge rollers or belts (not shown). In a modification, Fig. 8 (not shown), additional blowing rollers are provided above the sheet. The apertures in the rollers may be arranged in one or more helical series around the roller axis, Figs. 10, 11 (not shown). For handling curved sheets, the lower rollers are barrel-shaped and the upper rollers are formed with a corresponding concave profile, Figs. 12-14 (not shown).

Title: Improvements in or relating to "dry pipe" sprinkler systems for fire-extinguishing purposes
IPC: A62C35/64
Filed: 1928-11-09
Abstract: 318,790. White, A. E., (Automatic Sprinkler Co. of America). Nov. 9, 1928. Sprinklers, automatic. - In an accelerating device for a dry-pipe sprinkler system, the valve casing 13 of the system is formed with a chamber 20 communicating with the atmosphere by an outlet 21 adapted to be closed by a gravity valve 9 when the water valve 17 opens. The casing 13 communicates by a pipe 27 with a chamber 24 in an exhauster casing which is formed with partitions to define three chambers 22, 23, and 24 and which has a removable cover plate 25. The chamber 24 has an opening 28 connected to a draining pipe 61 for the system, and a restricted passage 33 to the chamber 23. The opening 28 is normally closed by a valve 31 connected to a plate 34 fast with a plate 37. A flexible diaphragm 35 is clamped between the plates 34, 37 and at its edge between the partition and a ring 38. The plate 37 has a stem 39 sliding in a core 40 in a plate 41 above which is a diaphragm 42 clamped between the second partition and a ring 44. A spring 8 is interposed between the plates 37, 41. The space above the diaphragm 42 communicates with the chamber 22 by way of passages 46 in a plug 45, and the chambers 22 and 23 communicate by way of a very small orifice 53 in a plug 54. The chamber 20 in the valve casing communicates with the chamber 23 by a pipe 47, and passage 48, the latter normally being closed by a valve 52 on a pivoted arm 51 the free end of which engages a shoulder on the plate 41. When the sprinkler system is ready for operation, air will be in all the chambers of the casing at the same pressure as in the sprinkler piping. When a sprinkler head opens, there will at once be a slight pressure drop in the piping and in the chamber 24, which is also communicated to the chamber 23 by the passage 33. The pressure drop in chamber 22 will be less, however, owing to the smallness of the orifice 53. Hence, the plate 41 will be forced down, opening the valve 52. Air will now pass rapidly from the chamber 23 to chamber 20, and so to atmosphere, so that the excess pressure in chamber 24 will raise the diaphragm 35 and open the valve 31. The pressure-air from the piping system can now escape rapidly by the large pipe 27 and opening 28, so that the water valve 17 quickly opens, allowing the valve 9 to close. Some water will pass to the exhauster casing by the pipes 27, 47 until the pressure in all three chambers is equalized, when the valve 31 will be closed again by the spring 8.
