Title: Liquid analysis method and apparatus
IPC: G01N35/08
Filed: 1962-12-18
Abstract: 1,033,146. Analysis systems; sampling devices. COLEMAN INSTRUMENTS CORPORATION Dec. 18,1962 [March 2,1962], No. 47773/62. Heading B1X. In determining desired constituents in a liquid by suitable processing and analysis, liquid is confined in a single flow path and unwanted constituents precipitated and separated during passage to the analyser. The liquid tested may be a single sample, a succession of samples or a continuous sample. As described the precipitate is separated by filtration. As illustrated in Fig. 2 (not shown), a pump 18 causes a reagent R1 to enter a sample stream in conduit 17 and after mixing in coiled tube 20, precipitating reagent R2 is added and the combined stream passed to a magnetic mixer 22. The stream flows on to a moving filter paper 24 where the solids are filtered out. The filtrate then passes through the de-bubbler 32 and after addition of reagent R3 through the proportioning pump 18, to the delay coil 40, the sample stream is batched by introducing the reagent R4 in slugs of liquid between air gaps. The stream is then passed through a heater 38 and de-bubbler 42 to the analytical apparatus 60. This may comprise a PH meter, a flamephotometer, titration device or, as shown, a colorimeter. From the colorimeter, voltage signals give a continuous indication of the analysis, which may be recorded graphically. Fig. 3 shows a sampling device which comprises a shelf 92 supporting trays 90, which contain the sample containers 12. A snorkel carriage 11 carrying an intake snorkel 14 and a diluent snorkel 88 is driven by rod 70 rotated by a motor 80 through selectively operable clutch 82. The carriage traverses the sample containers 12, pauses at a preselected one and draws off a sample for analysis. The sample may be diluted by means of the snorkel 88. The diluent snorkel 88 may alternatively be used to bubble air into a sample prior to its removal by means of snorkel 14. A cover 98 in the form of an endless band covers all but the sample directly below the snorkel carriage. A row of switches 9 is provided whereby, by depressing one of the switches the corresponding sample may be passed by the snorkel carriage.

Title: Vacuum forming or reduced-pressure moulding
IPC: B29C51/10
Filed: 1976-11-22
Abstract: The casting-mould pattern (3) has a shaft-like cutout (3a). The surface of the pattern, including the cutout (3a), is intended to be lined, in a finishing manner, with a single plastic sheet (5), without destroying the same. First of all, an opening, extending through the pattern (3), is produced and, therein, there is arranged a body (4) which is designed such that it corresponds in cross-section with the opening and can be displaced between a raised and a lowered position in which the body forms the base of the cutout in the pattern. When the body (4) in the cutout (3a) is in its raised position, a plastic sheet (5) is then made to adhere to the surface of the pattern and of the body (4), and said body is then pushed downwards into the lowered position. In this arrangement, the body takes that part of the plastic sheet which covers it along into the lowered position, with the result that a cutout (3a) lined by the plastic sheet is formed on the pattern (3). <IMAGE>
