Date Sep. 14, 1995Disclosed is a process for producing calcium cyanamide by reacting urea with an oxygen-containing calcium compound in at least two steps a) in a first step the reaction components are allowed to react under compression and/or while being revolved or by applying them to a hot surface at temperatures of 120 DEG  to 500 DEG  C. until a solid is formed and b) the solid reaction mixture that is formed is subsequently calcined at temperatures of 600 DEG  to 900 DEG  C. In this process it is possible to obtain high yields and throughputs of calcium cyanamide without requiring a time-consuming processing of the reaction product after the first or second step.

Abstract: 579,724. Making explosive mine casings; welding, GORDON, S. H. Jan. 22, 1940, No. 1311. [Classes 83 (ii) and 83 (iv)] An automatic electric resistance welding machine for welding edge to edge the components of hollow articles of circular crosssection, such as casings for explosive mines, comprises a series of separate sectional external electrodes arranged in the form of a ring for each of the two components, each electrode being separated from its neighbours by a small gap and each pair being connected to a separate transformer. The movable head 16 of the machine which is reciprocated by cams 42 on guide rods 18, carries a concave ring 28 to support one of the hemi-spherical parts 10 of the casing, and also twelve radially arranged hydraulically operated electrode blocks 48 with spherically shaped inner faces. To the upper edge of the part 10 may be welded a second hemi-spherical component or preferably first one of a number of cylindrical middle sections 12 of different widths and then after placing the welded parts in the upper fixed head 14 and the other part 10 in the lower head 16, this part is welded to the section 12. The upper head, which is pressed by springs 26 against stops 24 on the rods 18, carries a similar number of electrode blocks 50 to the movable head, the surfaces thereof being cylindrical so as to engage the middle section 12. Each pair of blocks 50, 48, is connected by flexible leads to the .primary of a separate transformer, the primaries being connected together so that they operate simultaneously. When making the first weld the section 12 is held in contact with the part 10 by an interchangeable ring 32 carried by an annular casting 30 placed in position by a derrick 36 and retained in the head 14 by wedges 38 actuated by hand levers 40. When performing the second weld the ring 32 is removed and replaced by a ring 34 with a spherical surface, Fig. 3. Two or more rings are provided to suit the width of the middle section of the article.

As described, X-cut quartz plates 6-of a thickness providing half wave acoustic resonance at the expected working frequency, and spaced apart to allow for thermal expansion-are mounted by epoxy resin on a faceplate 3 of epoxy resin, polyphenylene oxide, polyamide, or glass, with the interposition of an aluminized layer 5 forming a signal electrode, and a resilient layer 10 of synthetic rubber, to provide vibrational decoupling between plates 6 and faceplate 3. The anode 8 is held at 1000 volts with respect to the cathode, the scanning beam raising the varying surface potential of the piezo-electric plates 6 to the same value, on output signal being obtained either from the signal plate 5 or from a secondary electron collecting electrode. The tube envelope is of glass coated with the aluminium anode 8, or of copper or aluminium sealed to a glass envelope portion containing the gun 2. Due to poor keying of epoxy resin on to the aluminized layer 5, the latter is preferably comb-shaped (Fig. 2, not shown). An electrical filter is preferably included in the output circuit. The faceplate assembly is manufactured by bonding first the resilient material, and then the transducing layer, by combined heat and pressure.

[Also in Groups V and XXVIII] Helically-grooved pipe or hose is made by helically winding strip metal on a coiling mandrel, drawing off and helically corrugating the helically wound tube by internal and external rollers, and compressing the corrugations axially by hindering the feed of the tube from the corrugating means and smoothing or pressing their outer surface. Strip from reels 4, 4<SP>1</SP> on a rotor 2 is wound in an overlapping manner on a coiling mandrel 6, Fig. 1; 18, Fig. 4, and is drawn, therefrom and helically corrugated by a series of ribbed rollers 18<SP>1</SP> freely journalled in the periphery of the rotated mandrel 18, engaging the interior of the tube and co-operating with a series of ribbed rollers 14<SP>1</SP> engaging the exterior of the tube and freely journalled in a ring 14 rotated around the tube at the same speed as the mandrel 18. The delivery of the grooved tube from the mandrel is hindered and the corrugations compressed axially by a fixed sleeve 21 engaging the outside of the tube and any rotation of the tube is stopped by a member 29 carried by a rod 28 passing through the mandrel. The corrugations are smoothed or pressed on their outer surface, as they leave the corrugating rollers, by peripheral smoothing rolls 25 carried by a ring 23 rotated around the tube by a shaft 27. The rollers 25 may be cylindrical or frustoconical with their small ends facing the corrugating means. In a modification, Figs. 10, 12, the corrugating means comprise a ring or nut 30, having a thread 31 and an inclined roller 33 journalled at the beginning of the thread, and a mandrel or worm 34, with a thread 35 and roller 37. Two or more grooving rolls may be arranged successively in the path of the threads 31 or 35. In an arrangement, Figs. 2, 3, described as known an externally-threaded mandrel 6 co-operates with a threaded nut 8 rotated at the same speed as the mandrel to corrugate the tube, the nut 8 being formed with a groove smoothing surface 13.

Abstract: 832,502. Measuring linear displacement. BRITISH THOMSON-HOUSTON CO. Ltd. Jan. 9, 1957 [Jan. 17, 1956], No. 1592/56. Class 40 (1). Linear displacement is measured by a selsyn whose movable member is connected to the displaceable object by means of a crosshead and connecting rod. The object 1 moves in the direction of the arrows and carries a rod 2 to which is attached a crosshead 3. The arm 6 is fixed at one end to the selsyn rotor and the other end slides along the crosshead as the latter moves up and down. The voltage output of the selsyn is proportional to sin # and therefore to the algebraic value of the distance of the crosshead above the line AA. The device .can be protected from the atmosphere and hence used under humid conditions such as in the investigation of the behaviour of model ships in a tank.
