Abstract: 518,808. Drilling and logging wells. HAYWARD, J. T. Jan. 25, 1939, No. 2602. Convention date, Jan. 29, 1938. [Class 85] A hydraulic fluid circulating system for use in the drilling and logging of wells comprises a meter for measuring the flow of mud fluid and means for sampling the fluid before and after a given flow whereby a comparison may be' made of selected properties (e.g. viscosity, cblour, salinity, or gas, oil or cuttings contents) of the fluid when entering and when leaving the well so as to identify the strata encountered by changes in said properties. Pumps 10 draw'mud from a pit 9 and force it through the drill string 4, the mud returning outside the drill string and flowing through ditch 6 to a settling pit, 7 which overflows through ditch 8 to the pit 9. A chemical hopper 16 and water supply pipe, 17 are provided for re-conditionihg the mud. A sample of an increment of mud in the ditch 8 is taken by means 15 and, by means of a meter 13 arrival of said increment at the ditch 6 is noted, when a further sample is taken by means 14 ; the two samples are then compared to permit identification of the strata being drilled. By a series of such tests, the complete well is logged, and by comparing the logs of adjacent wells, the contour of the strata may be mapped. Gas contents of a sample may be noted by subjecting a sample to a vacuum and noting increase in volume, and oil contents by centrifuging. U.S.A. Specification 1,819,923 is referred to.

Abstract: 284,650. Picard, J., and Tournadre, A. Feb. 2, 1927. [Convention date]. Thermal switches. - An apparatus for giving warning either of rapid heating or of a slow rise to a predetermined temperature comprises a pair of elements, Fig. 1, each comprising a band 12 of highly - expansible material stretched between a pair of curved springs 7, 11. The lower spring 7 of each element is secured to a base 4 by a screw 6, and the upper spring 11 carries a contact plate 14 to coact with an adjustable screw 15 arranged in an electric circuit and carried by a bar 16 supported on uprights 17, 18, Fig. 3. The springs 7, 11 of one element are formed of material having a very low coefficient of expansion, and the springs of the other element are of high expansibilitv but are thicker than the strip 12 and are covered with heat-insulation 13. Upon a slow rise of temperature to a predetermined degree the first element operates the alarm, since the springs 7, 11 do not expand, whereas the second element operates only on a rapid rise in temperature, when the band 12 heats and expands more quickly than the insulated springs. The operating temperatures of the elements may be regulated by the screws 15 or by varying the effective lengths of the bands 12 and springs 7, 11. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a construction wherein the apparatus comprises one only of the elements, or wherein the two elements are arranged in separate circuits. It states also that each element may comprise the band 12 and one only of the spring strips, and that the alarm may be actuated through electrical, mechanical or pneumatic devices.

Abstract: 395,055. Feeding webs. HARRIES, A. W., 31, Cole Park Road, Twickenham, Middlesex. Feb. 1, 1932, No. 2981. [Class 100 (i).] In a rotary web-printing machine in which printing takes place during only a part of the rotation of the impression cylinder, the feed of the web through the couple being arrested during the non-printing period, and in which the web is fed continuously from the reel to form a loop from which the supply to the couple is drawn, devices are provided adapted to act alternately to tension the web between a guide roller and the couple during the printing period and to draw a supply from the loop and tension the web between the guide roller and a stationary guide at one end of the loop during the non-printing period. The web g, Fig. 1, is drawn continuously from the reel A by feed rollers b to form a loop g2 and passes over a stationary guide 2, and guide roller k, between the impression cylinder c and coacting printing cylinder and thence between feed rollers, the driving shaft f<1> of which may be driven intermittently as described in Specification 389,621. During the printing period the stretch of web between the roller k and couple is held taut by spring fingers n, Fig. 2, secured to a shaft m and held against the roller k by a spring t connected to an arm s on the shaft m. During the non-printing period, the fingers n are moved away from the shaft k, as shown, by means of a cam q, Fig. 1, on the shaft of the cylinder c acting through a rod p and arm o on the shaft m. During this period also, a cam y driven from the cylinder c allows a pivoted frame x to fall thereby drawing a supply of web from the loop g<2> and tensioning the web between the roller k and guide 2. This frame carries a pair of bars 4, 5 which co-operate with a fixed bar 3 to draw forward and tension the web, the tensioning being assisted by spring fingers 8 which are engaged and depressed by the bar 5 against the action of a spring 10 secured to an arm 9 on a shaft 7 carrying the fingers. During the printing period, the frame x is again raised, the upward movement of the fingers 8 being limited by a stop 11 in the path of the arm 9. Specification 389,246 also is referred to in the Provisional Specification.

Abstract: 760,498. Cutting grass &c. WENINGER, P. Feb. 2, 1954 [Feb. 2, 1953 ; Sept. 23, 1953] No. 3010/54. Class 5(1). [Also in Group II] A process of communuting grass, cereals and other materials consists in feeding the material through a casing which is free from transverse projecting partitions and consists of a zone of increasing cross-section in the direction of feed followed by a zone of uniform cross-section, subjecting the material in the zones to the action of striking or cutting elements and discharging the comminuted material through a regulatable opening. As shown in Fig. 1, the casing consists of an initial part 1 of truncated conical form leading to a cylindrical part 2. Hammers 14, 15 which may have stepped heads are provided in both parts pivoted on bolts 13 on cruciform mountings secured on a driven shaft 3, the hammers 14 in the part 1 being of gradually increasing length in the direction of feed and the hammers 15 in the part 2 of uniform length ; one, two or four hammers are pivoted on each mounting plate and the distances between the adjacent mounting plates may be decreased in the direction of feed. Knives 7 are mounted on the shaft 3 at the entrance to the part 1 of the casing. Material is fed to the knives down a shoot 21, together, if desired, with other material which is fed along a platform 40 and passes through an opening in the side wall of the shoot; this opening is provided by either opening a hinged door 38 or adjusting a slide 37 covering an opening in the door. Water or other liquid may be added through an opening 41. An adjustable slide 18 controls the discharge of the ground material from either the second part 2 or both parts of the casing ; the degree of grinding may be controlled by varying the time at which the slide is opened. In the modification shown in Fig. 4, the discharge of material through an opening 25 at the end of the second part 2 is controlled by an iris screen or, as shown, by an adjustable slide 27. Instead of discharge at the end of the second part 2, a third section 34 of tapering form with hammers of appropriate length may be provided as shown in Fig. 6, and this may be followed by a fourth section of cylindrical form containing hammers of uniform length ; three pairs of slides 42, 44, 46 control discharge from the section 34. The mill shown in Fig. 10 has a truncated conical section 1 followed by cylindrical sections of progressively increasing diameter ; discharge is controlled by a slide 18 and, if desired, a slidecontrolled opening may also be provided in one or more of the cylindrical sections. If desired, material pre-ground by a hammer mill arranged on the shaft 3 may be blown for mixture with material fed down the platform 40 and further comminution in the apparatus. In a further modification, the hammers may be replaced by knives.

Abstract: 1,118,772. Liquid heaters. ELECTRICITE ET ELECTROMECANIQUE S.A., and R. S. J. FONTAINE. 26 Jan., 1966 [5 Feb., 1965], No. 3560/66. Heading F4A. Oil to be heated flows from pipe 14, upwardly through a spiral path defined by barrier strip 7 welded between coaxial shells 5 and 6, through connecting pipe 21 into spiral tube coil 4 and then through connecting pipe 22 into a second spiral path defined by barrier strip 17 welded between coaxial inner shells 15 and 16, to outlet 20. The pipes of the coil 4 constituting the lower turns have a smaller diameter than the middle and upper turns, whilst the pitch of the helical path between the inner coaxial shells 15, 16 is less at the middle than at the extremities of the shells. The closer pitch corresponds to the zone of maximum heat radiation from a burner (not shown) which fires downwardly into the inner space within shell 16, the gases from which flow in counter flow up around the coil 4 and down around the outside of the outermost shell 5. In this way the rate of heat absorption of the oil per unit length of helical path between the shells 15, 16 is maintained constant. The double-walled shells are formed either by continuously welding the barrier strip 17 to the outer surface of the inner wall 16 and winding a metal ribbon in overlapping turns around the outer edge faces of the barrier strip and welding it thereto, which overlapping metal ribbon then constitutes the outer wall 15, or by spot welding the strip 17 to the inner wall 16 and then resistance welding a preformed outer wall to the strip and the inner wall, using a welding machine.
