Patent GB-2461181-A (GB)
Title: Bidirectional transient blocking unit
Inventor: MORRISH ANDREW J
IPC: H02H3/22
Filed: 2009-06-26
Abstract: A transient blocking unit (TBU) is an arrangement of two or more transistors connected to each other in series such that they automatically switch off when a TBU current passing through these transistors exceeds a predetermined threshold. Voltage turnoff capability is provided for a TBU by adding a voltage comparison circuit to the TBU. The voltage comparison circuit provides gate voltages to one or more of the TBU transistors that tend to turn off the TBU transistors, if the voltage at the TBU output (i.e., the protected device output voltage) falls outside a predetermined range. The voltage provided by the voltage comparison circuit adds constructively to the gate voltages provided by normal TBU operation. Accordingly, TBU switch off can be driven by an over-current condition (TBU current out of range) and/or by an over-voltage condition (TBU output voltage out of range).

Filed: 1918-06-19
Abstract: 117,612. Surface Combustion Co., (Assignees of Eddison, W. B.). July 2, 1917, [Convention date]. Mixing fluids in flow.-In a gas-mixing device in which one gas draws a second gas into a Venturian mixing- tube, the part of minimum cross-sections is made of a length approximately eight times greater than its diameter so that the pressure of the gaseous mixture at the part where it enters the conical discharge part of the mixing-tube is substantially the same at any point on a transverse section. Fig. 2 shows a mixing-device for the burner of a surface combustion furnace. The Venturian mixing- tube 20 extends into an air chamber 13 preferably to a point beyond the air in. lets in one side of the chamber 13 sc that the end of the gas nipple 25 is in the same plane as the end of the mixing-tube. The gas nipple 25 has a removable tip 26 and is screwed through a partition separating the gas chamber 11 from the air chamber 13 so that the nipple can be removed from the back of the chamber on removing a cap 27 normally held in position by a yoke 28 and a screw. The throat 23 of the mixing-tube may be of uniform diameter, or may be of uniform diameter for a part of its length and slightly divergent for the remainder, or may be slightly divergent for the whole of its length; the angle of divergence with respect to the axis of the tube is not more than 2¢ degrees and is substantially less than the angle of divergence of the conical discharge part of the tube, which latter angle is preferably 5 degrees. The area of the throat 23 is from 50 to 100 times the area of the gas nipple orifice and may be 3/5 the aggregate area of the discharge orifices of the burner heads. The mixing-tube 20 may have two or more throats 23 of increasing size. The flared entrance 21 of the mixing-tube should preferably be of a length equal to or somewhat less than the diameter of the throat 23 of the tube. The air inlets to the air chamber are provided with a hit-and-miss regulator 30 connected by a link 32 to a shut-off valve 33, and the openings in the regulator 30 can be adjusted by a plate 31. Air is supplied at a pressure approximately equal to the furnace pressure. The mixing-tube 20 is secured to the air chamber 13 by means of a shouldered flange, and the gas supply is regulated by a second valve in the gas pipe 10.

Abstract: 168,931. Mitchell, F. G. April 10, 1920. Feeding-devices for portable endless-chain pushplate or scraper conveyers and elevators.-Relates to conveyers of the kind in which an endless chain of scrapers, push-plates, or equivalents j<1> is carried by a portable structure adapted to present the scrapers to the base of a dump or heap of loose material. The chain passes round wheels of which the one h adjacent to the dump has its axis g vertical, the arrangement being such that the removal of the material is effected close to the ground. According to the invention, there is provided beneath that portion of the chain of scrapers which enters the material a rotary disc i adapted to facilitate the entry of the scrapers. The disc rotates about an axis coincident with or parallel to that of the wheel which, turning about a vertical axis, causes the chain of scrapers to travel in a horizontal plane as it enters the dump.

Abstract: 622,898. Reaping-machines. BAMFORD, C. J., and BAMFORD, H. V. April 17, 1947, No. 10179. [Class 6(iii)] Relates to a mowing-machine having a laterally-extending cutter bar, the mower being coupled at its forward end to a tractor and being supported rearwardly on caster wheels. According to the invention, a power lift for the cutter bar comprises a clutch mechanism mounted on a transverse shaft and driven continuously by gearing from the power take-off, the clutch mechanism being connectable with lifting gear for at least a part of a revolution of the transverse shaft and being disconnected automatically on completion of the lifting operation. The power take-off is coupled by a universal joint 18 to a longitudinal shaft 17 which drives the transverse shaft 25 through a worm and worm-wheel, and drives the reciprocating cutter bar through a belt drive 19 to the usual cam and connecting rod mechanism. The clutch device comprises a continuously-driven ratchet 28 and a lever 29, pivoted on the shaft 25 and connected by a link 38 to a bell-crank 39, 43. Rotation of the bell-crank about its pivot 41 raises the cutter bar through linkage 44, 53, the system being self-sustaining in its raised position as a result of its passing through a ' dead-centre position and being maintained therein by a spring 46., The lever 25 carries at its outer end a pivoted lever 32 fixed to a pawl 31 and connected by a cable to the tractor. On the pulling of the cable, the pawl engages the ratchet and the cutter bar is raised. The pawl is carried around with the ratchet and the lever 25 and is released upon striking a fixed abutment 37. The ratchet 28 may be replaced by a half-revolution clutch similar to that described in Specification 617,481. Specifications 505,788 and 519,165 also are referred to.

Title: The manufacture of softening agents for textile goods containing artificial silk
IPC: D06M13/402
Filed: 1931-02-27
Abstract: As softening agents for textile goods containing artificial silk, use is made of mixtures of water-insoluble saturated fatty acid amides or N-substitution products thereof (other than N-hydroxyalkyl substitution products) with sulphonation products of oleic amide or its N-substitution products.  The softening agents may be prepared by mixing the saturated amide or substituted amide with oleic amide or N-substitution product thereof, and sulphonating the mixture with a sufficiently restricted proportion of sulphonating agent and (or) at a sufficiently low temperature to avoid sulphonation of the saturated amide.  In the examples, (1) a solution of oleic amide and stearic amide in trichlorethylene is treated with sulphuric acid monohydrate at 0-5 DEG  C., and the product is poured on ice, separated from the aqueous layer, and neutralized with caustic soda; (2) a mixture of oleic acid ethylanilide and stearic acid ethylanilide is sulphonated and worked up as in example (1); the corresponding diphenylamides may be similarly treated; (3) a mixture of oleic acid diethylamide and palmitic acid diethylamide is sulphonated and worked up as in example (1).  The softening agents may be added to the finishing bath or the dye bath.  The Provisional Specification refers to Specification 328,675, [Class 2 (iii), Dyes &c.].

[Glasn 40 (iv)] [Also in Group XL (c)] A sub-aqueous compressional wave sender or receiver comprises a cup-shaped metal base 20 having mounted on it an insulating ring 25 to form an annular space in which are disposed radially a number of piezo-electric elements 10 having edge electrodes 12, 13 engaged in contact clips on ring 25 and casing 20 respectively. The elements are connected in parallel to conductors 36, 37 of a cable 35 which passes through a fluid-tight seal in the base of the casing. The casing is closed by a rubber diaphragm 44 held by a clamping ring 46, and is filled with castor oil through a plug 43. The useful piezo-electric movement of the crystal elements is along the axis of the instrument. Movement in a direction normal to the major surfaces is decoupled from the oil filling and hence from the useful movement, by covering the major faces with a layer of a cork and rubber plastic. An external layer of cork 34 reduces radiation from the rear face of the casing 20. In a modification (Figs. 5 and 6, not shown), instead of coating the crystal faces, the crystals are assembled in radial slots in a spider formed of a cork and rubber composition.
