Abstract: 212,543. Kaye, E., J., (Assignee of Petra Akt.-Ges. f³r Elektromechanik). March 8, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Clutches, claw.-The driving shaft of a kinematograph apparatus is provided with a sliding coupling sleeve which, when the direction of drive is reversed, is moved automatically to reverse the driving connection to the film spools; the feeding sprocket is loose on its shaft and the movement of the sleeve is transmitted by means of a rod and lever system to a coupling disc for connecting the sprocket wheel to its shaft and disconnecting it therefrom. When the shaft e is rotated in the direction indicated, the pin g sliding in the slot h of the sleeve i moves the sleeve i into engagement with wheel n driving one of the spools, so that the shaft k is rotated and also the sprocket shaft w, through gearing w<1>. A rod r slides within the shaft k and is moved by the sleeve i by means of collars o, p. This rod r actuates through a lever s the rotating sleeve v to clutch in the sprocket wheel y when the pin x is opposite the hole x<1>. The lever s is pivoted on a fixed pin t and is connected to the lever r by a link s<1> pivoted on the pin t'. A spring u is fitted as shown to bring the lever and link in line with one another. Movement of the rod r to the left turns the links s<1> about the pin t<1> and through the action of the spring u brings the pin x on the sleeve v in contact with the face of the sprocket, until the hole x<1>can be engaged bv the pin x when the linkage is straightened by the spring u and the sprocket wheel y is rotated by the pin x. The reverse movement of the rod r turns the lever s about the pin t and de-clutches the sprocket wheel.

Patent GB-975301-A (GB)
Title: Production of sulphamic acid
IPC: C01B21/093
Filed: 1963-02-11
Abstract: Sulphamic acid is produced by reacting together urea, sulphuric acid, and sulphur trioxide, or urea bisulphate and sulphur trioxide, using chlorosulphonic acid as reaction medium at a temperature of 60 DEG to 95 DEG  C.  External cooling may be applied to maintain the reaction mixture within the temperature range indicated. The sulphamic acid precipitates from the reaction medium, and may be removed by filtration, and purified by heating to 150 DEG  to 160 DEG C. at atmospheric, or reduced, pressure. The urea is preferably added to an agitated mixture of the sulphur trioxide and sulphuric acid in the chlorosulphonic acid over a period of 5 minutes to 2 hours, preferably 20 minutes, and the temperature is maintained, during the addition, between 60 DEG  and 80 DEG  or 85 DEG  C., preferably 75 DEG  to 80 DEG  C., at substantially atmospheric pressure. The temperature is then raised to 80 DEG  to 95 DEG  C., preferably 85 DEG  to 90 DEG  C., until the formation of sulphamic acid is complete.  The urea is preferably added in the solid form, and the other reaction materials are kept above 60 DEG  C. so that the sulphamic acid is formed and precipitated from the chlorosulphonic acid while the urea is being added.  After the addition of the urea is complete, the temperature is desirably increased to 80 DEG  to 95 DEG  C., preferably 85 DEG  to 90 DEG  C., to accelerate the formation of sulphamic acid (known as the "digestion phase").  Using temperatures of 80 DEG  to 90 DEG  C. the total time for completing the reaction, after the addition of urea is complete, is from 20 minutes to 3 hours. In the alternative procedure the sulphuric acid is premixed with the urea, at below 80 DEG  C., to form urea bisulphate, which is preferably maintained in the liquid form at 80 DEG  to 85 DEG  C., and is then added to the sulphur trioxide and chlorosulphonic acid.  The reaction is desirably carried out at 80 DEG  to 85 DEG  C. for 10 to 20 minutes, and the digestion is at 80 DEG  to 90 DEG  C. for 10 to 20 minutes.  Optimum yields are obtained using substantially equimolar proportions of urea, sulphur trioxide and sulphuric acid, although an excess of sulphur trioxide may be employed.  A molar ratio of sulphur trioxide to urea of 1.3 to 1 gives satisfactory results.  The range of molar ratios of chlorosulphonic acid to urea or urea bisulphate is suitably 1 : 1 to 2: 1, preferably 1.2: 1 to 1.5: 1.

Abstract: 1,214,151. Semi-conductor devices. ASSOCIATED SEMICONDUCTOR MFGS. Ltd. 5 Feb., 1968 [7 Feb., 1967], No. 5717/67. Heading H1K. A semi-conductor device comprises a semiconductor wafer with at least first, second and third regions 31, 32, 33 of successively opposite conductivity type, the first region 31, which may be annular, underlying a depression 39 in one face of the wafer and the PN junction 36 between the second and third regions having a stepped formation under the first region with its periphery extending to a bevelled surface 45 of the body. The peripheral surface of the wafer is bevelled and the angle between this junction 36 and the surface is between 170 and 180 degrees. Electrodes are connected to the regions. In the embodiment shown in Fig. 3 where the device is a thyristor a further conductivity region 34 exists in the wafer opposite the depression 39, and a further bevel exists at the peripheral surface at an angle of between 15 and 60 degrees with the PN junction 37. The emitter electrode 51 may overlap the second zone 32 in selected areas to provide shorted emitter characteristics. In a further embodiment, Fig. 1, not shown, the depression (9) is annular with the first zone (1) surrounding the depression. In a thyristor of this type the control electrode (23) is connected in the centre of the annulus to the second region. In the manufacture of the silicon device the second region 32 is formed in a composite manner by firstly diffusing gallium to give a relatively deep P region, the depression 39 then being formed by etching or ultrasonic drilling, and secondly diffusing boron to form a narrow width portion of the region particularly under the depression. Electrodes are provided by electroless plating of nickel and gold, and the wafer is soldered, after plating, to a molybdenum disc 56 with an interposed gold-germanium preformed solder disc.
