Patent GB-667303-A (GB)
Title: Apparatus for use in filling a succession of moulds or trays with ice cream or like plastic material from a continuously operating extrusion nozzle
IPC: A23G9/28
Filed: 1949-10-04
Abstract: 667,303. Extruding ice-cream into moulds on trays. COMBES, A. E., and COMBES & SONS, Ltd., W. Oct. 27, 1950. [Oct. 4, 1949] No. 25531/49. Class 87(ii). Apparatus for filling a succession of moulds 4 from a continuously operating extrusion nozzle 6 includes intermittentlyoperable means for moving two moulds in tandem, one into the stationary filling position, the other away from this position, and an automatically-operated cutter 21. The mould 4<SP>1</SP> is shown at rest in the filling position with its trailing edge a short distance a behind the extrusion nozzle 6. Spring-pressed plates 18 on either side of the mould provide enough friction to hold it in position during filling. As soon as the mould is full, lever 16 controlling hydraulic cylinder 15 is moved from the central neutral position (see Fig. 5) to the lefthand position and movement of carriage block 12 in the direction of the arrow is initiated. Simultaneously, solenoid 26, controlled by the lever 16<SP>1</SP>, is momentarily energized to activate the cutter 21. The trailing edge of the cut-off position of extruded material falls into the mould 4<SP>1</SP> and the mould 4<SP>11</SP> is pushed into the filling position by the carriage block 12 to receive the leading edge of the next portion. As soon as the carriage block 12 reaches its extreme right-hand position (shown in broken line) a rod 40, moving with the block in the direction of the arrow, trips a spring- loaded catch 38, thereby allowing articulated frame 31, 32, 33, 34 to be pivoted in a right-hand direction under the influence of spring 37. Link 35, connecting the rods 33, 34 to the pivot spindle of the lever 16<SP>1</SP>, thereupon moves the lever into the right-hand position (not indicated on the drawing) and initiates return movement of the carriage block 12 and rod 40 to the starting position shown. As soon as this position is reached the rod 40 engages and moves the articulated frame against the spring 37 into its former position where it is retained by the catch 38. The lever 16' is, at the same time, returned to the neutral position. An empty mould 4 is now placed between the carriage block 12 and the mould being filled. A lost motion connection between the spindle of the lever 16<SP>1</SP> and the link 35 allows the lever to be moved to the left-hand position when it is desired to restart the mould-feeding cycle. This may be done automatically by a time switch or by a trip device actuated by pressure of the extruded strip as it engages the leading end wall of the mould being filled. The carriage block 12 may be in the form of a spring-biassed flap past which the empty tray may. be passed during return motion of the block.

Title: Method for determining the position of an interface separating two liquids
IPC: E21B47/04
Filed: 1970-05-28
Abstract: 1312719 Determining liquid level GA Z DE FRANCE 28 May 1970 [30 May 1969 20 May 1970] 25727/70 Heading G1A To determine the level of an interface 20 between two liquids, e.g. a column of petroleum oil 16 supported on brine 18 which is filling an underground cavity, a radio-active tracer is introduced at the interface and a detector monitors the radioactivity produced by the tracer. This method of interface detection can be used when an underground cavity is being excavated in salt-bearing rock by pumping water down an inner tube 13, pumping brine away up a second tube 12, and introducing the oil into an outer tube 11 to prevent erosion of the cavity roof. The tracer is either introduced directly into the oil or is introduced into a volume of water which sinks down the oil column until it reaches the interface. The y-ray detector is lowered down the inner tube 13 and its output, which is displayed in graphical form as a function of depth, decreases as the interface is passed. Spurious peaks and depressions on the record may be produced by radio-active material in the surrounding strata. To eliminate their effect, after a first suspected interface indication, more oil is introduced to depress the interface a known amount. If the detector produces a second interlace indication this known depth below the first, then the interface has been detected. The area of the cavity at a known depth below the surface may also be measured. This is done by introducing a known volume of water containing a tracer into the oil. When the water layer (60), Fig. 11 (not shown) reaches the brine/  oil interface it spreads out to form a layer whose thickness depends on the cavity area. The detector signal level also depends on the layer thickness, and hence provides a measurement of area.
