Title: Testing swell characteristics of swellable materials
Inventor: NUTLEY BRIAN
IPC: G01M99/00
Filed: 2009-10-28
Abstract: Swell characteristics of swellable components used in downhole exploration or production equipment, such as swellable packers, are tested by placing a test piece in a fluid chamber. The change in dimension (e.g. thickness) of the swellable material is measured by displacement of the test piece, or by displacement of or pressure applied to a target plate to which the test piece applies force as the material swells (figures 6 & 7). The test piece may be in the form of a disc having a recess filled with the swellable material to be tested (figures 4A & 4B). Measured test piece data 210 is compared 240 with data measured from a swellable component 220, e.g. a sample section of a tool, to determine a relationship between the swell characteristic of the test piece and a swell characteristic of the swellable component 250. The determined relationships can then be used to calculate or predict swelling characteristics of swellable components, for example particular packer designs, in specific fluid samples.

Abstract: 720,914. Flame safety controls for burners. RHEOSTATIC CO., Ltd. April 13, 1953. No. 10027/53. Class 75 (1). In a flame safety device for a fluid or pulverized fuel burner of the flame conduction or flame rectification type comprising a probe 1 projecting into the flame, electrical leakage from the probe assembly to earth is intercepted by a metal guard ring 9 surrounding the probe terminal 3 or by metal parts supporting and surrounding the probe insulator 5 or by a metal screening tube 12 surrounding the probe itself over a large portion of its length or by two or more of the above intercepting members, each intercepting member being connected in a protective circuit so as to signal a fault condition when leakage occurs between the probe assembly and the member. The probe insulator 5 is held by a metal sleeve 7 and metal washers 8 in a metal cup 6 secured by screws to the guard ring 9 and to an insulating terminal plate 2 to which the terminal end of the probe is clamped. The unit thus formed is secured to the upper surface of an insulating base 11 to the underside of which the screening tube 12 is secured; the securing screws connect the screening tube electrically to the guard ring. The protective circuit is shown in Fig, 2 and comprises an electrical source connected at 16, 28, a protecting resistance 17, an earthed burner 18, the burner flame 23, the probe 1, the inner core 19 of a coaxial cable and a load resistance 22 connected to an amplifier operating a relay controlling the burner fuel valve. The outer conductor 20 of the coaxial cable is clamped to the guard ring 9 and is-also connected to the end of the load resistance 22 connected to the electrical source and consequently leakage between the probe and the ring 9 or cup 6 &c. or between the inner and outer conductors of the cable does not cause a current to flow in the load resistance. The probe assembly assembly is mounted in a casting 13 secured to the furnace wall and staggered ventilation holes 26, 27 are provided in the coating and in the screening tube 12 to reduce moisture condensation.

Relates to a device in which cigarettes 4, carried in grooves of a chain conveyer 2, are moved past a photo-cell which determines whether or not the brand imprints on the cigarettes are uppermost, and controls in known manner pins 8 on rotatable discs on a turning wheel 9 by rotating certain of the discs so that the respective pins, e.g. the pin 8<1>, engage one end of each of those cigarettes without their brand imprints uppermost, and turn them in co-operation with a clip 7, spring holding-down blade 5, and sponge 6, through the intermediate position 4<111> into a position with their brand imprints uppermost. To avoid the other ends of the cigarettes moving forwardly and the cigarettes becoming askew, which would interfere with the turning action, these ends are engaged by a further spring blade 12, adjustable longitudinally and vertically, the outer end of the blade being bent to engage the top and forward edges of the cigarette being turned.

Abstract: 1,202,985. Valves. GENERAL GAS LIGHT CO. 5 March, 1968 [8 March, 1967; 12 May, 1967], No. 10710/68. Heading F2V. [Also in Divisions G4-G6] A pneumatic device is responsive to a preset number of pulses to produce an output pulse and restore itself. A selector knob 32, Fig. 2, is pulled out and turned together with transverse rod 39 to indicate the preset number on a dial, the knob being then located by engagement of a fixed pin 37 with one of a series of recesses 36. Movement of the rod 39 carries along an upstanding rod 43 on a ratchet wheel 27, against the action of a torsion spring 46. Pneumatic pressure applied to inlet port 148 presses a detent pawl 97 against ratchet wheel 27. The first pulse also operates driving pawl 67 which turns wheel 27, detent 97 being cammed backwards until it snaps over the next tooth. The wheel 27 is advanced stepwise until at the preset count its pin 48 drives slide 102 to the left, so moving valve 127, Fig. 5, to the left. Pressure air is thereby fed to port 152 to operate an external load. At the same time pressure is fed through passageway 157 into chamber 92 to release the detent 97. When the pressure in the system falls sufficiently for driving pawl 67 to return under spring action the wheel 27 is restored by torsion spring 46, and the system is ready to repeat the count.
