The overlapping ends of two lengths 21, 25 of material having contacting thermoplastic surfaces are spliced by locating these ends between an anvil 11 and an ultrasonic horn 17 having plane working surfaces 15, 19, respectively, inclined at an acute angle to one another, the overlapping ends being orientated relative to the horn 17 and the anvil 11 so that the cut edge of the material adjacent to the horn 17 is located at the narrower end of the gap between the horn and the anvil. The angle between the surfaces 15, 19 is not more than 45 degrees, preferably 2-5 degrees with film 0À001-0À015 inch thick. In one embodiment, Fig. 1, the anvil 11 is made of steel and is provided with a channel 13 having an inclined floor 15 upon which the overlapping ends are located. Ultrasonic vibrations are imparted to the metallic horn 17 by a magnetostrictive or piezoelectric vibration generator.

Title: Improvements in and relating to the preparation of dichloro-or trichloro-cyanuric acid or mixtures thereof
IPC: C07D/
Filed: 1959-10-14
Abstract: Di- or tri-chlorocyanuric acid, or a mixture thereof, is prepared by reacting cyanuric acid, alkali, and chlorine in water maintained at a pH not exceeding 9 and 5 - 40 DEG C., the ratio of equivalents of alkali to mols. of cyanuric acid corresponding to the numebr of Cl atoms to be attached to each cyanuric acid molecule, and recovering from the mixture at a pH adjusted to 1,5 to 3,5 the precipitated chlorinated cyanuric acid.  By maintaining a pH 1,5 to 3,5, the reaction may be carried out continuously, in a single stage.  The alkali may be alkali metal hydroxide, e.g. NaOH, although carbonates are also mentioned.  The cyanuric acid is used as a slurry in the aqueous alkali. Alternatively, the reaction may be effected continuously in two stages, wherein alkali and cyanuric acid are added to the first stage, maintained at pH5-9 and 5 DEG -40 DEG C., together with only part of the required Cl2, and a portion of the mixture is fed to the second stage, maintained at pH 1,5-3,5 and 5 DEG -20 DEG C. together with at least sufficient additional Cl2 to form the desired product.  The gases from the second stage may be used in the first with additional Cl2.  In preparing dichlorocyanuric acid, half the total Cl2 requirement is used in the first stage, while for trichlorocyanuric acid the proportion is 60 - 65%.

Abstract: 1479255 Boring earth &c S L BASS 22 Aug 1975 [5 Nov 1974] 34880/75 Heading E1F A drill collar stabiliser e.g. 26A, 26B or 26C, Fig. 1B, comprises a rigid main sleeve 36, Fig. 5, having an axial passageway 41, 43 intermediate the length of which is a fixed abutment 44 extending inwardly from the passageway surround and defining an opening sufficient to permit the sleeve 36 to be slidably received over a drill collar 22. Flanges or blades 38 extend radially outwardly of the sleeve 36, and clamping means e.g. wedgeshaped split slip rings 46, 52, are positioned adjacent the abutment 44 and are engagable by clamping actuator means e.g. a threaded cap sleeve 58, for clamping the sleeve 36 to the collar 22. The abutment 44 may be an annular rib rather than a shoulder, a second set of slip rings and cap sleeve being provided in the lower half of the main sleeve for additional clamping. Each stabiliser may be formed with upwardly- and downwardlyfacing clutch jaws 66, 39 so that if, in use, the drill string is seized by a formation cavein (as at 100, Fig. 1) and a washover operation is initiated, a washover tool 102 cuts through the upper part of the uppermost stabiliser 26A until the clamping means are released, the stabiliser then moving down to engage the next stabiliser 26B, cutting then proceeding until the clamping means of stabiliser 26B are released. The process is repeated until the drilling obstruction is cleared, the bit itself being provided with an upwardly-facing clutch jaw 32 that may either be integral or be provided on a separate short collar-type pipe section received between a conventional bit and the lowermost collar section.

Abstract: 1,143,723. Freeze drying. KRAUSSMAFFEI A.G. 31 July, 1967 [10 Aug., 1966; 23 June, 1967], No. 34991/67. Heading F4G. [Also in Division B1] Freeze drying apparatus comprises a stack of heated platforms 2 in an evacuated chamber 1, material being introduced at 22 and discharged at 21. The platforms are alternately of larger and smaller diameter with respectively larger and smaller central openings. Paddles 19, 20 on a central shaft 12 sweep the material inwards to the central openings of the larger platforms, where it falls on to the platforms below, and outwards over the edge of the smaller platforms on to the platforms below. The platforms are hollow and are heated by fluid passing through pipes 8, 10, 9. To prevent material from the inlet 22 bouncing over the edge of the top platform, the pipe may have a flexible or pivoted extension or have pivoted baffles (Figs. 3-7, not shown). The inlet 22 is connected through a gate valve to the lower part of a charging chamber (25, Fig. 2, not shown) which has hollow walls (27a) for cooling fluid and comprises a frusto-conical part with a rotary bottom wall (34) carrying a paddle (38a) which sweeps the material into the lower part. A distributing cone (36) upstanding from the bottom wall has radial projections (37) which prevent agglomeration of the material. The outlet 21 discharges into a wheeled bin (40), which may be evacuated prior to use (via connection 47) or filled with inert gas after use (via connection 46).
