Abstract: 1,016,151. Typewriters. LAMSON PARAGON Ltd. Nov. 23, 1962 [Sept. 29, 1961], No. 35360/61. Heading B6F. Line spacing mechanism.-A mechanism for feeding continuous stationery webs comprises a rotary solenoid 3, Fig. 4, having an axially movable armature co-operating with a rotary disc (not shown) with helical indentations and balls mounted therein so that as the armature moves axially the disc is displaced both axially and angularly. This movement is imparted to a first feed-plate 4 fast with the disc and having a pin 5 engaging a slot 7 of a second feed-plate 6 rotatably mounted on a drive-shaft 10. The angular or rotary displacement is transmitted to the shaft 10 by pawls 8, Fig. 3, on the feedplate 6 engaging a ratchet-wheel 9 fast on the shaft, which in turn is coupled to an output shaft (not shown) for feeding the continuous stationery one single feed movement. To vary the feed movement the output shaft may be coupled through a variable gear-box (not shown). The plate 6 has a camming surface 12 cooperating with a micro-switch 13 connected in the circuit of the rotary solenoid so that at the end of the feed movement the cam will operate to de-energize the solenoid which will return to its inoperative position. Ink-ribbon mechanism.-The mechanism may be used for feeding of carbon webs interleaved with webs of stationery fed around the platen of a typewriter.

Abstract: 754,643. Refrigerating. ELECTROLUX, Ltd. Dec. 9, 1954 [Dec. 9, 1953], No. 35637/54. Class 29. In an evaporator for continuous cycle absorption systems of the inert gas type formed of horizontally disposed concentric pipe members the inner one of which receives an ice tray, the inner member is formed with a flat ice tray supporting surface. The inner member may have a rectangular cross section but, as shown, it consists of a square pipe 17 having a rear wall 19 disposed within a circular pipe 13. The top and sides of the pipe 17 are covered with wire gauze 21 the bottom parts of which may dip into liquid refrigerant in the bottom of pipe 13. Two or more evaporators may be  disposed side by side. As shown, two freezing chambers 10, 11 are provided one above the other and liquid refrigerant is supplied to the evaporator space of the top chamber through pipe 20. Inert gas is supplied by pipe 22 and after traversing the top evaporator flows into the bottom evaporator through pipe 23 and is returned, enriched with refrigerant, through pipe 24 to the absorber. The pipe 13 circumscribes the pipe 17 and the inert gas passes through the gauze 21 at the edges. If the gauze is too fine, it may be gapped or omitted at the edges of pipe 17 to form gas channels. Alternatively, the gauze may be held in place by a helically wound heat-conducting strip which spaces the pipes 13, 17 and forms channels between its turns for the gas. Alternatively, the segments formed by pipes 13, 17 may be supplied in parallel or in series with inert gas by means of suitable pipes, and by openings in pipe 22. The front of the unit is provided with a plate 31 formed with apertures registering with the freezing compartments 10, 11. A finned casting 28 cools the cooling space of the refrigerator.

Title: Improvements in or relating to the production of nitrogenous vapour mixtures
IPC: C01C3/20
Filed: 1960-10-20
Abstract: A mixture of ammonia and cyanic acid vapour is produced by feeding urea into or on to a bath of molten metal at a temperature of at least 230 DEG C., said molten metal being inert to urea, ammonia, and cyanic acid.  The process may be continuous, and the molten metal may be lead or tin or a mixture thereof.  The temperature of the metal bath is preferably 400 DEG -510 DEG C., and the bath may be agitated. The temperature of the metal bath and the feed rate of the urea may be so chosen that the urea vaporizes substantially immediately but such high feed rates that cyanuric acid and/or ammelide is formed transistorily on the surface of the metal may be used, provided the so-formed surface layer is allowed to vaporize by cutting off the urea supply for a few minutes.  The best operating conditions are a temperature of 413 DEG -427 DEG C., and a heat supply of 3,1 106 joules per kilogram of urea.  The gaseous mixture of ammonia and cyanic acid may be used directly for producing melamine, or converted to ammonium cyanate by chilling, or treated with alcohols to give urethanes.ALSO:A mixture of ammonia and cyanic acid vapour, for use in the production of melamine is produced by feeding urea into or on to a bath of molten metal at a temperature of at least 230 DEG C., said molten metal being inert to urea, ammonia and cyanic acid.
