Patent GB-2094528-A (GB)
Title: Method and apparatus for measuring while drilling
IPC: E21B47/01
Filed: 1978-12-04
Abstract: Logging the characteristics of a borehole while drilling involves generating pulses of pressure drop in the liquid (drilling mud) pumped to circulate in the boreholes, in response to parameters sensed down the borehole, by rapidly opening and shutting a valve in a comparatively wide bore passage which bypasses the drill head or hydraulic motor which restricts mud flow in the borehole. A receiver (100) in the high pressure side of the mud flow path and positioned at the earth's surface is equipped with means (102) to eliminate from the received signal the "noise" which is due to pressure variations arising from pulses due to the pump (12). This elimination involves deriving groups of pulses for each information pulse. <IMAGE>

Title: Producing ceramic parts
Inventor: LUNDMARK GUNNAR
IPC: B28B13/04
Filed: 1982-10-29
Abstract: Apparatus for producing parts of porcelain articles, in particular reliefs for jasper porcelain, is described in which porcelain pieces are cut from a pugged roll of porcelain (2) by a cutter (4) and are then individually transported by a thin film (8) in between film (8) and film (10) and are positioned above an engraved matrix (16) in which the required relief pattern has been engraved in negative. A die (20) presses the porcelain piece down so that it fills out all the pattern components in the matrix. At the same time, any surplus porcelain is cut off between the die (20) and the edge around the matrix engraving without damaging the films (8, 10). The stamped relief adheres to the upper film (10) and is then transported from the upper film (10) via a conveyor belt (25) for further processing while the surplus waste porcelain is transported by the film (8) to a further conveyor belt (24). <IMAGE>

Title: Short smoking devices
Inventor: WALLIS NEIL RUDOLPH
IPC: A24D1/00
Filed: 1982-11-06
Abstract: To enable a cigarette smoker to regulate more easily the amount smoked, cigarettes are provided with a filter tip or other unsmokeable part at each end. The cigarette, in the condition in which it is supplied, is hence totally unsmokeable and some deliberate action on the part of the user is required to cut the cigarette into two smokeable parts, which, if of equal length, are shorter than normal, thus providing an opportunity for reducing the quantity of tobacco consumed. If the cigarette is severed to provide parts of unequal length, these may be assigned to different and appropriate social occasions. <IMAGE>

IPC: B01D53/04
Filed: 1983-03-04
Abstract: Apparatus 1 for adsorbing adsorbable constituents contained in a fluid stream, comprises a cylindrical container 2 which has outwardly convex, opposite, ends 3 and 4 and which is substantially horizontal. The container 2 has a plurality of superposed, spaced apart devices 5 and 6 which are each permeable to a fluid stream and capable of supporting an adsorbent material, for example activated carbon or charcoal in a bed 7a or 7b. The permeable devices 5 and 6 run the whole length and width of the container 2 (Fig. 2). There is an impermeable, inclined partition or baffle plate 8 which runs the whole length and width of the container 2 and which is higher at the righthand end and lower at the lefthand end. The partition 8 is joined as be welding to the end wall 3 of the container at or just below the device 5 and is secured to the opposite end wall 4 as by welding above the device 6 (and above, in use, the upper level of the bed of activated carbon 7b). The partition 8 thus forms two chambers respectively an upper chamber 9 and a lower chamber 10, in the container 2. The upper chamber 9 contains the device 5 and bed 7a, and the lower chamber 10 contains the device 6 and bed 7b. <IMAGE>

Title: Removal of ions from charged powder clouds
Inventor: HUGHES JOHN FARRELL
IPC: B03C3/53
Filed: 1983-08-01
Abstract: A charged powder cloud (for example emerging from a corona gun 1) has free ions removed from it by being caused to pass through a conductive grid (suitably comprising a series of wires 3) to which the ions are attracted. To prevent the occurrence of "back-ionization" on the grid, a film of water is caused to flow over its surface so as to inhibit deposition of powder thereon. After passage through the grid the cloud may be collected on a plate 2 for the purpose of measuring charge-to-mass ratio of the powder; alternatively a coating may be formed on a workpiece by deposition of powder from the cloud. <IMAGE>

Title: Gel and process for retarding fluid flow
Inventor: MARROCCO MATTHEW L
IPC: C09K8/588
Filed: 1984-07-17
Abstract: A gel-forming composition is provided comprising a first substance selected from the group consisting of a polyvinyl alcohol, a polyvinyl alcohol copolymer, and mixtures thereof, with an aldehyde operable for crosslinking with the first substance, and water. Suitable aldehydes include glutaraldehyde and a polymeric aldehyde obtained by oxidation of polyvinyl alcohol. The gel-forming composition is useful for filling voids in porous substances and for retarding the flow of fluids in high permeability channels in an oil reservoir. Such method is particularly useful in waterflood operations to increase the sweep efficiency of the oil recovery process. Since these gels have very good stability at elevated temperature they can be used in reservoirs having an average in situ temperature of 80 DEG C or higher.
