Title: Economical and efficient tritium sepn. - involves passing gas to molten electrodes to ionise molecules, wash tower for absorption and condensate prodn.
IPC: B01D53/46
Filed: 1990-09-14
Granted: 1991-08-22
Abstract: Tritium is sepd from a gas stream by a process in which the gas, contg. O2, is passed to a reaction body (34) contg. molten electrodes (31,32) to produce energy-rich electrons which ionise the molecules in the stream. Stream passes to an appts (40) for absorption, with a wash tower (41) for absorbing tritium water with a perforated base (42) to produce small gas bubbles. Condensate is produced in a cooling system (44) and runs back into the tower while wash bottles (45,46) dry the gas stream. ADVANTAGE - Economical and efficient sepn. method.

Title: Gas flushing brick for melting vessels - has gas channels slightly inclined to vertical to ensure that gas flow is towards centre of vessel despite non-vertical fitting of brick inside vessel bottom
IPC: B22D1/00
Filed: 1992-03-12
Granted: 1993-08-26
Abstract: Gas flushing brick for metallurgical vessels in which the gas feeding channels are inclined slightly to the vertical axis of the brick. The channels are parallel to each other. The inclined channels pref. run the whole length of the channel section with a pref. inclined angle of 1-10 deg. to the vertical. The channels may be made by plate sections fitted agianst each other with intermittent grooves formed in the plates. Alternatively the channels are formed by spacer holders located between the plates. The plates are surrounded by gas-tight ceramic covers. ADVANTAGE - Despite the fact that the brick is never exactly vertically fixed into the bottom of the vessel, the gas flow from the channels is always directed towards the centre of the vessel thereby avoiding premature wear to the top side of the vessel.

Title: Process for the extrusion blow moulding of hollow articles from thermoplastic material
Inventor: FEUERHERM HARALD
IPC: B29C48/92
Filed: 1994-06-03
Granted: 1995-05-11
Abstract: The invention relates to a process for the extrusion blow moulding of hollow articles from thermoplastic material, in which tubular preforms are extruded by means of an extruder and, in following work cycles, the extruded preforms are expanded in a blow mould to form hollow articles, the hollow articles are moulded and any flash is removed. According to the invention, for each preform the extrusion time required to reach a predetermined parison length is measured and its deviation from a set value is determined. If the set-value deviation lies outside a predetermined operational tolerance band, a signal assigned to the preform is stored. The signal controls a sorting apparatus for rejecting defective hollow articles when the hollow article blow-moulded from a preform provided with a signal reaches the sorting apparatus. The hollow article concerned is then rejected. <IMAGE>

Abstract: A spotlight mounting 10 is adjustable to mount on various diameters of guide rod 14, and is lockable thereto. Brake 36 restrains longitudinal movement of the light along the rod, even when the rod is sloping. It is pressed against the rod by a spring (not shown), and may be released by pulling on handle 38. In order to release the carriage from the rod, bar 24 is depressed against the action of spring 28 (fig. 4), to release it from cavity 30 and past cam 32. Swinging part 20 then swings away from the rod under gravity, around pivot 22. Part 20 is restrained in its maximum opening position by rod 24 resting against abutment 34. Numeral 12 denotes rollers; the gap "S" between abutments 16 and 18 determines whether rod 14 can be removed. <IMAGE>
