Filed: 1917-09-27
Abstract: 118,357. Wade, H., (Booth-Hall Co.). Sept. 27, 1917. Electrode furnaces.-One or more hearth electrodes, situated directly beneath the main electrodes, are replaced at starting by an auxiliary upper electrode, until the hearth has been heated to conductivity. Alternating current is preferred. In a single-phase furnace, one terminal of the supply transformer may be connected to the main upper electrode, and the other terminal to the adjustable auxiliary electrode and hearth electrode. In the two-phase furnace shown, two main upper electrodes C<1>, C<2> and two hearth electrodes B<1>, B<2> are connected so that the phase currents cross in the charge. The auxiliary electrode D<1> is connected permanently to one hearth electrode B<2> and at starting is also connected, say through a switch H', with the other hearth electrode. A three-phase furnace may have three main upper electrodes and one hearth electrode which, with the auxiliary electrode, is connected to the neutral point of one or more supply transformers. Auxiliary electrodes are preferably adjusted by hand, and main electrodes automatically by an electric motor, through rack-and-pinion and worm gear in each case. Arcs are preferably struck, at starting, from the main electrodes only, the auxiliary electrode being maintained in contact with the scrap-metal &c. charge; afterwards the auxiliary electrode is raised so as to become inoperative. A hearth electrode may consist of a mass of carbon filling or enclosing an iron or steel grid having a water-cooled projecting terminal.

Title: Improvements in thief resisting shutters for the protection of shop premises and thelike
IPC: E06B9/01
Filed: 1932-08-09
Abstract: 391,985. Window guards. LEWIS, F. J., Exeter Works, West End Lane, Kilburn, London. Aug. 9, 1932, No. 14533. [Class 20 (iii).] Relates to protecting shutters for shop windows and the like, of the kind in which the shutter is held in its retracted position by means associated with an electromagnet and is released to fall into its operative position when the circuit of the electromagnet is interrupted as the result of the breakage of the window. According to the invention, the circuit is closed by a switch comprising two arms which become separated when the window is subjected to a heavy shock but which move together when a steady pressure or only a slight vibration is applied to the window. In the form shown, the shutter comprises a plurality of telescopic tubes each consisting of a number of sections 4-9, Fig. 1, which are carried by cross-bars 10 .. 13. In the raised or inoperative position, the sections 5 .. 9 are housed in the uppermost section 4 and are retained thus by a pivoted bell-crank lever 21 which engages with a pin 20 on the lowermost cross-bar 13. The horizontal arm of the lever 21 is pivotally connected to the armature of an electromagnet 25, arranged in a circuit which is normally closed by contacts 26, 27 on two pivoted levers 28, 29, Fig. 3. These arms are held together by two springs 32, 33, the tension in the latter being adjusted by means of a nut 34. A piece of strip metal 30 firmly held at its upper end and bearing against the window 1 at its lower end is adapted to register the shocks and vibrations received by the window and to transmit such movements to the lever 29 by means of an arm 31. With a slight shock or steady vibration, the springs 32, 33 keep the contacts 26, 27 together; under a sudden shock, the contacts are separated by the arm 31, thus breaking the circuit and releasing the lever 21 from its engagement with the cross-bar 13. The cross-bars are recessed at their ends to engage a rib on the side frames 19 of the window 1. A section 35, Fig. 6, of this rib may be pivoted to the remainder and carries a contact 37 which closes the circuit of an alarm bell 39 should a wedge be inserted between this section and the cross-bar 13. A spring-urged member may be provided on the window sill to engage with and hold the lower ends of the sections 9, and spring clips on the cross-bar 13 engage with an annular rib 15 on each member 9 when the shutter is collapsed.

IPC: B64C25/50
Filed: 1956-05-10
Abstract: 808,438. Vehicle power steering. CLEVELAND PNEUMATIC TOOL CO. May 10, 1956, No. 14559/56. Class 79(5) [Also in Group XXXIII] Mechanism for controlling the direction of rotation of a rotatable element, e.g. a steerable aircraft undercarriage leg comprises a support element for the rotatable element, first and second cylinder members and associated fluid actuated piston members, a mounting portion on each member extending generally in the same direction, each cylinder mounting portion being connected to one of said elements and each piston mounting portion to the other element, at least one cylinder pivot and its associated piston pivot being equally spaced from the axis of rotation of the rotatable element, and stabilizing means between the cylinder members to prevent uncontrolled rotation thereof. In Figs. 2 and 3 twin-aircraft ground wheels are mounted at the foot of an inner cylinder 11 forming a shock absorber with an outer cylinder 10. A collar 14 is rotatably mounted on the cylinder 10, and is connected to the cylinder 11 by a scissors linkage 16, so that the wheel may be steered by rotating collar 14. Two mounting portions 19 on cylinders 17, 18 are pivoted at 22 to lugs 21 on cylinder 10, and two mounting portions on the piston rods 26 are pivoted at 31, 32 to lugs 29 on the collar 14. The cylinders have fluid pressure ports 33 and 34. The collar is rotated by admitting fluid under pressure to the port 33 of one cylinder and the port 34 of the other. At some point in the steering range, pivot 32 will be aligned with its associated piston rod pivot 22, whereupon the cylinder 18 will be free to swing about these pivots. To prevent this a bar 36 is pivoted to the cylinders at 37, 38. Similarly, when pivot 31 is aligned with its associated piston rod pivot 22, the cylinder 18 and bar 36 prevents cylinder 17 from swinging. The pivots 37, 38 are equidistant from the associated pivots 22. In Fig. 9, the arrangement is such that when the wheel is in the neutral position, the associated cylinder and piston rod pivots of cylinder 119 coincide at 136, and those of cylinder 121 at 138 and both cylinders are free to swing. To prevent this, a bar 143 is pivoted to the cylinders at 144, 146, and is formed with a tooth 147 engaging a notch 148 formed in the collar. Each cylinder rotates relatively to the fixed cylinder 10 with half the angular velocity of the collar, and the tooth 147 and notch 148 are located half way between the axis of bar 143 and the axis of the collar, whereby the tooth and notch have the same velocity when the wheel is turned from the neutral position, and their successive positions are shown in chain dot lines in Fig. 9. Fig. 10 (not shown) shows a modification in which the two pivots associated with cylinder 119 are further from the axis 137 than those of cylinder 121, though the pivots of each associated pair are equidistant from axis 137. Co-operating abutments on the collar and fixed cylinder limit the range of steering.

Filed: 1966-04-01
Abstract: 1,138,298. Polyesteramides. MONSANTO CO. 1 April, 1966 [21 April, 1965 (2)1, No. 14581/66. Heading C3R. Polyesteramides of the formula wherein R is an aliphatic or cycloaliphatic radical and A is a p-phenylene or 2 : 6-naphthylene radical, provided that A cannot be a p-phenylene group when R is an ethylene group, are prepared by reaction of terephthalic acid diamide N : N<SP>1</SP> - di - # - caproic acid or 2 : 6- naphthalene dicarboxylic acid diamide N : N<SP>1</SP>- di-#-caproic acid or an ester-forming derivative thereof with an excess of an aliphatic or cycloaliphatic diol, in the presence of a polycondensation catalyst. The diamide di-caproic acid or, e.g. its dimethyl ester may be obtained by reaction of the dicarboxylic acid dihalide with #-caproic acid or, e.g. its methyl ester. Suitable glycols are ethylene, propylene, butylene and cyclohexane dimethylene glycols. Usually the di-(glycol ester) is first formed at, e.g. 175-195 C. This may be kept if required, or prepared by a different route, e.g. using ethylene oxide. Then polycondensation is brought about at higher temperatures, e.g. 230-250 C. and pressures of, e.g. 0À1-5 mm. Hg. Preferred catalysts are sodium hydrogen titanium hexaisopropoxide and zinc acetylacetonate, in amounts of, e.g. 0À001-2 wt. per cent of the acid. In Example 1 dimethyl 2 : 6 naphthalene dicarboxylic acid diamide N : N<SP>1</SP>- di-#-caproate (from the acid dichloride and caprolactam-1 : 2 molar ratio-followed by esterification with methanol) is condensed with ethylene glycol i.p.o. zinc acetylacetonate. In Example 2, terephthalic acid diamide N : N<SP>1</SP>-di-#-caproic acid (from aqueous sodium caproate and terephthalyl chloride in CHCl 3 ) is esterified with methanol and reacted with cyclohexane dimethylene glycol i.p.o. sodium hydrogen titanium hexaisopropoxide.
