Title: Method and apparatus for investigating earth formations
IPC: G01V3/30
Filed: 1974-08-22
Abstract: 1484200 Well logging SCHLUMBERGER Ltd 22 Aug 1974 [23 Aug 1973(2)] 36878/74 Heading G1N Micro-wave well-logging apparatus has a transmitter and two receiving antennas spaced along the log-tool whereby the dielectric constant of the earth formations can be determined from measurements of the phase difference and attenuation between the two received signals. The antennas may be cavity-backed-slots Figs. 6, 7 (not shown). In a basic arrangement Fig. 1, the transmitting antenna T is fed by oscillator 45, and the received signals from R1, R2 are heterodyned by beat oscillator 49 which is connected in a phaselocked-loop 50, 51 with the transmitter 45. The phase difference of the "intermediate" frequency signals is determined by phase detector 53, and the attenuation is determined by amplitude comparator 54. A more sophisticated PULSED SYSTEM is shown in Fig. 9, with two transmitting antennas T 1 ', T 2 ' alternately energized through switch 247 driven by a squarewave M from generator 260. In this system the received intermediatefrequency signals are fed to detectors 271, 272, which produce spiked pulses III, IV Fig.11, every time the signals I, II cross zero, in a positive direction, as shown. The phase displacement of the spikes is measured by a sub-system 270. The spikes are fed to gates 273..276 operated in synchronism with the antenna switch by pulses M, M from 260. These gates determine the duration of setting and resetting flip-flop 277 whose output pluses V, Fig. 11, are integrated at 278.  Similarly a subsystem 280 is M, M switched to differential amplifier 289 to measure the average attenuation.  From the dielectric constant information about the porosity, saturation or lithology of the strata may be estimated.

Abstract: 1474443 Electro-erosion; drawing ATELIERS DES CHARMILLES SA 22 Aug 1974 [24 Aug 1973] 36906/74 Headings B3V and B3P An electro-erosion machine having a moving wire electrode 2 comprises means 12 for heating the wire 2, means 10 for tensioning the heated wire 2 in a zone 14 upstream of the working zone, and means 17 for increasing the traction on the wire 2 and means 15 for cooling it as it passes from the straightening zone 14 to the working zone. In one embodiment, the wire 2, before entering a work tank 1 where it erodes a workpiece 3, is heated by an electric current supplied by a generator 12 between a guide 13 and a drum 7 against which the wire 2 is pressed by an endless band 8. The wire 2 is straightened by applying traction by a brake block 10 on the drum 7, which traction is less than that applied to the wire 2 by a mechanical brake 17 as the wire 2 is passed through the tank 1. Before entering the tank 1, the heated wire 2 is cooled in a chamber 15 by the working liquid supplying the tank 1. The wire 2 is pulled from the tank 1 by a device 19. In another embodiment, the wire 2, before passing over the drum 7, is calibrated by a drawing die (26) (Fig. 3, not shown) through which it is drawn by a drum (28). The speed of the drum motor (27) is controlled, to obtain the required traction in the zone 14, as a function of the position of a pulley (29) which is determined by a photo-electric cell (34). The tension on the wire in the zone 14 may be applied by the pulley (29). In another embodiment, the wire is heated by an induction coil (23) (Fig. 2, not shown) and the traction is applied by driving wire feeding means (19, 21, 22) at different speeds.

Filed: 1974-08-22
Abstract: 1440731 Feeding foam beads to moulding apparatus POLYMER PROCESSING RESEARCH INSTITUTE Ltd 22 Aug 1974 [7 Sept 1973] 36967/74 Heading B5A [Also in Division C3] In a method of moulding expanded polystyrene beads using at least one endless belt, the partially expanded beads are assembled in a single layer on the belt prior to passage through a pressurized steam chamber by wetting the belt with a liquid, e.g. water, feeding the beads in excess on to the wetted surface, and removing those beads not retained by the surface tension of the liquid. A single layer of beads may be formed on a single belt 21, Fig. 2, or on each of a pair of opposed belts 1, 9, Fig. 1. Excess beads may be removed by inclining a belt by at least 40 degrees to the horizontal, by using a weak air stream or by passing the belt along a run so that the beads are suspended therefrom. The surface of a belt may be wetted by spraying, e.g. 4, 11 or 22 or passing the belt through a tank. The excess beads are collected and returned to a feed hopper 3, 23 by a pneumatic device. The belt may be formed of a cloth which is permeable to the steam in chamber 28 and which may have at least its edge portions turned over to envelop the retained beads (see Fig. 1d). The loaded belt(s) is passed through pinch rollers, 15, 26 and into the steam chamber 28 where the beads are expanded and consolidated by heating them for 10-30 secs. at at least 100 C. under a pressure of 1-1À2 kg/cm<SP>2</SP>. The belts pass over a plurality of rollers so that uneven thickness due to local increases in the number of layers of the beads is evened out. The chamber is provided with seals 27, 30. The consolidated beads, e.g. in the form of a sheet are passed through a cooling tank to a wind-up reel 40. To form an even thinner sheet, a belt may be provided with non-wettable lateral strips so that the beads only adhere to a belt between the strips, and when passed through rollers are spread laterally to consolidate. The sheet of expanded polystyrene may have a thickness of 0À5-5 mm, a weight per unit area of 20-60 g/cm<SP>2</SP>, may be heat shrinkable; embossed incorporate fabrics, threads or stretched tapes and further expanded in a steam chamber at 80-95 C. under atmospheric pressure.

Abstract: 1441923 Spinning and finishing yarns IMPERIAL CHEMICAL INDUSTRIES Ltd 8 Aug 1973 [15 Aug 1972] 38003/72 Headings D1F and D1W In a process for making variable knap yarn, a first filamentary comiponent is passed from a feed means through, in sequence, heating, falsetwisting and knap-forming zones and a second filamentary component is introduced, by positive or free feed, between the feed means and false-twisting zone so that it becomes wrapped around the first component and subsequently formed into knaps by Ibeing rubbed back by a friction device e.g. a ceramic guide. The components may comprise a synthetic e.g. polyester, monofilament, continuous filament yarn or a bonded yarn or a combination of any one thereof with discontinuous fibres and continuous filament(s) or discontinuous fibres e.g. of a polyamide, or a combination thereof. Variations in the size and frequency of occurence of knaps is effected by altering the feed rate of the second component, the count thereof or the frictional properties of the knap-forming device. Knap yarns which have been oppositely false-twisted may be doubled or intertwisted e.g. by one turn per inch, to form knitting yarn. As shown, a multifilament yarn 1 withdrawn from package 3, through a tensioner 4 and guide 5 by nip rolls 9 and 11, passes through a guide 13, a heater plate 15, falsetwisting pin 17 or an annular friction twister (not shown). A multifilament yarn 19 withdrawn under low tension from package 21 through a guide 23, wraps helically and unidirectionally around yarn 1 at a point which oscillates. In the resultant combined core yarn 24, which is heat set on plate 15, the sheath possesses (along the length of the yarn) portions of 'S' and 'Z' twist separated by portions without significant twist. The yarn then passes over a friction guide 25, Fig. 2 (not shown) which forms the knaps 35 along the core which travels therewith through nip rolls 29 and 31 to be wound into a package 33.
