Patent FI-971805-A (FI)
Inventor: VALARIS PETER
IPC: H01L39/24
Filed: 1997-04-28
Abstract: A cylindrical billet of superconducting material is enclosed by a copper sheath circumferentially, and by a lid and nose of copper at its longitudinal ends. A short cylindrical nose piece of lesser diameter than the billet, is attached at the billet's front end. At the rear end of the billet, an annular ring of copper is positioned. The billet is enclosed in a liner leading to a convergent conical die. Longitudinal force is applied by a ram to the annular ring, which pushes against the outer periphery of the billet at the rear end in a direction toward the die orifice. The stepped nose piece deforms against the die. During an initial period wherein no extrusion takes place, the nose piece exerts an opposite reactive force on the center of the billet, moving the center material toward the ram. As a result of these two opposite actions on the billet, the central longitudinal portion of the billet is pushed back (upset) toward the ram and deforms into the opening of the annular ring. As ram force further increases, the billet breaks through the die opening and actual extrusion of superconducting rod commences. As a result of using a complementary combination of annular ring and stepped nose piece, wherein the stepped nose piece diameter approximately equals the diameter of the annular ring opening product yield is significantly increased.

Abstract: 936,441. Ratchet gearing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 2, 1962 [Jan. 9, 1961], No. 94/62. Addition to 932,113. Classes 80 (2) and 80 (3). In a two-speed ratchet gear, two pawls 26a, 26b on pawl actuating arms 14a, 14b are driven in opposite phase in cyclic manner to move the pawls into and out of engagement with parallel sided notches 30 in a ratchet 28a, 28b, means being provided to latch one pawl arm to prevent that pawl moving the ratchet, whereby the ratchet is driven at a lower speed when the pawl arm is latched. In a punched card feed mechanism, a driving-shaft 12 carries two cams 13a, 13b, 180 degrees out of phase, which oscillate a forked pawl lifting member 34 and pawl arms 14a, 14b, respectively. The lifting member arms 36a, 36b are arranged to lift the pawls out of the notches on the return stroke. A pawl may be held from engagement, to provide a half-speed drive, by electromagnet 41 having a " hold " coil 41a and a " bucking " coil 41b, under which condition the pawl enters a notch to prevent back-running but does not drive the ratchet. In a second embodiment, Fig. 2, (not shown), the pawls are arranged to impart step-by-step motion to linearly moving notched rods.

Abstract: 1514351 Automatic control of light intensity ELECTRONICS CORP OF AMERICA 12 Jan 1976 [15 Jan 1975] 01018/76 Heading G3R [Also in Division G1] The output of a light source 62 used in a monitoring system for particulate matter on a smokestack 56, is regulated by control of an electronic switch 20 in the circuit between a power source 16 and the source 62, control of switch 20 being effected by a feedback circuit 42, 28 including a sensor 40 monitoring the output of the source 62. The sensor 40 is a reversed biased semi-conductor diode and is connected in series with an adjustable resistor (72) Fig. 2 (not shown). At the beginning of each positive half cycle the lamp is energized and illuminates after a brief thermal lag. On reaching the threshold set by the adjustable resistor (72), the feedback circuit, made up of a series of transistors, switches, to turn off transistor 20. The lamp is not powered during negative half cycles, unless a further transistor is connected in the other power supply line as in Fig. 4 (not shown). It is stated that by this method, the filament is maintained at a substantially constant temperature giving spectral stability, compensation for film deposits on the lamp bulb and lower power consumption achieved.

Title: Process for recovery of the alkali metal content and terephthalic acid from aqueous solutions of dialkali metal terephthalates
IPC: C07C51/02
Filed: 1958-01-13
Abstract: Terephthalic acid is recovered from an aqueous solution of one of its dialkali metal salts, such as is obtained by extracting with water the product prepared by heating an alkali metal salt of a benzene carboxylic acid other than terephthalic acid, and the alkali metal content of the solution is also recovered in the form of a readily-utilizable salt, by acidifying the solution with a slight excess of sulphuric acid to precipitate terephthalic acid, separating the terephthalic acid from the solution of alkali sulphate, adjusting the water-content of the solution (by evaporation or by addition of water) so that the weight-ratio of water to alkali sulphate is between 10:1 and 4:1, adding the calcium salt of a benzene carboxylic acid (other than terephthalic acid) to the solution to precipitate substantially all the sulphate ions as calcium sulphate, and separating the calcium sulphate from the aqueous solution of the alkali metal salt of the benzene carboxylic acid.  The final solution may be used directly as a starting material for the production of further quantities of terephthalic acid.  The calcium salts of the following acids may be used to precipitate the sulphate ions:-benzoic acid, ortho-phthalic acid, isophthalic acid, and benzene carboxylic acids that contain three or more carboxylic groups.  Instead of adding the calcium salt itself, one may add simultaneously calcium hydroxide and the benzene carboxylic acid which react together in situ.  An excess of calcium should be avoided.  The final solution of the alkali metal salt of the benzene carboxylic acid may be freed from any excess calcium by adding an alkali metal carbonate, when calcium carbonate is precipitated.  The recovery process may also be applied to the treatment of the aqueous solution of a dialkali metal terephthalate obtained by alkaline hydrolysis of certain synthetic fibre wastes.  Specifications 744,721 and 747,204 are referred to.

Filed: 1917-09-11
Abstract: 118,686. Scholey, H.. and Woodroffe, F. K. Sept. 11, 1917. Feed-water, controlling.- The supply of feed-water is regulated by the expansion and contraction of oppositely inclined pipes A arranged with their junction-piece B at the normal water-level and communicating at their free ends through flexible connexions with the boiler steam and water spaces. When the water-level rises, water enters the upper pipe, which contracts and operates the feed-regulating means through a lever E so as to lessen the feed-supply. Expansion of the lower pipe, due to the entrance of steam when the water-level falls, causes the lever E to turn upon the pivot E<1> connecting it to the upper pipe so as to open the feed-supply means. The link F between the lower tube and the lever is provided with several pivot-holes H<1>. Further adjustment of the apparatus may be made by means of the nuts in the bolt securing the junction-piece to the base-plate D.

Title: Improvements in radio aerials
IPC: H01Q15/00
Filed: 1949-01-20
Abstract: 665,747. Aerials. BRISTOW, H. M., and BUCKINGHAM, J. Jan. 20, 1950 [Jan. 20, 1949], No. 1620/49. Class 30 (vii). A scanning aerial system comprises a primary element 5 associated with a lens 7 made of a non-dispersive dielectric medium and a prism 10 made of material, the refractive index of which varies with frequency in the operating frequency band. By varying the frequency of radiation from the wave-guide flare 5, the directivity of the radiation emerging from the prism 10 may be varied. The frequency modulation may be effected by means of a small moving mechanical member or by means of a reactance valve so that very rapid scanning may be achieved. The lens and prism are constructed of artificial dielectric media comprising metallic particles distributed uniformly throughout a homogeneous dielectric of low refractive index. The metallic particles may comprise discs of zinc sprayed on to a sheet of insulating material; preferably, however, they comprise short strips 14, Fig. 4, of metal sprayed or stuck on to an insulating sheet. Several such sheets are stuck together to form a block of the artificial dielectric material. In the lens medium the metallic particles are of small size compared with the operating wavelength so that the medium is substantially non- dispersive. The prism material, however, comprises metallic particles having dimensions comparable with the operating wavelengths so that they are capable of acting as resonant half-wave dipoles over the operating band of frequencies, whereby the medium of the prism is dispersive, the refractive index thereof varying with frequency.
