Patent GB-2172629-A (GB)
Title: Flow method and apparatus for well cementing
Inventor: KELLER STUART R
IPC: E21B33/14
Filed: 1985-03-18
Abstract: A fluid such as drilling mud or preflush fluid is oscillated in the annulus (26) between the casing (14) and wall of a wellbore prior to introduction of cement slurry into the annular interval to be cemented. The fluid is oscillated by changing its direction of flow at least twice. The oscillatory flow of the fluid flushes gelled drilling mud and filter cake from the annulus more effectively than conventional unidirectional flow. Following the oscillatory phase, cement slurry is pumped into the annular interval to be cemented, thus displacing the fluid. The cement slurry is allowed to set. The fluid can be oscillated in the annulus either before or after the cement slurry is introduced into the casing. A selective check valve (46) permits all fluids to flow in the forward direction out of the casing (14) and into the annulus (26) and permits all fluids other than cement slurry to flow in the reverse direction out of the annulus (26) and into the casing (14). <IMAGE>

Title: Label apparatus
Inventor: ELLIS ARTHUR JOHN GEORGE
IPC: B26D7/18
Filed: 1986-03-20
Abstract: Superimposed strips (G, Figure 1) of labels form a block B, each strip being partly severed along line P to delineate individual labels L which are very narrow compared to their length. Thus the block consists of a number of stacks S1, S2 etc. of labels L, joined along the lines P. The block B is fed over a table 1 and as each stack S1, S2 in turn extends byond the table edge, the leading stack is gripped between jaws 4, 6 which are given a sharp knock downwards by a bar 24 and cause the stack to become separated from the block B.

Title: Specimen processing system
Inventor: COMBS JOHN W
IPC: B01L3/00
Filed: 1987-02-27
Abstract: A specimen preparation unit having a plurality of interconnected compartments is automatically loaded onto a centrifuge rotor arm at a first rotor position. Each rotor arm has two indexing means for independently rotating the unit about either or both of two axes orthogonal to each other and to the rotor arm. The orientation of the unit with respect to the centrifugal force vector is changed in a predetermined manner so as to cause fluid flow between desired compartments even under conditions of microgravity. The unit is centrifuged in at least two different orientations with respect to the centrifugal force vector. As the fluids move between compartments, the specimen is prepared. After the multistep preparation process is completed, the unit is rotated to another rotor position at which the prepared specimen and/or the entire unit is removed. The centrifugal processing unit is capable of processing a plurality of specimen preparation unit in the same or a different manner. A plurality of the compartments of the specimen preparation unit are connected by force-sensitive valves which prevent reflux and which respond only to forces substantially exceeding gravity.The specimen preparation unit may provide for parallel processing of specimen aliquots. <IMAGE>

Patent GB-2198283-A (GB)
Title: Laser apparatus
Inventor: MENOWN HUGH
IPC: H01S3/036
Filed: 1987-11-23
Abstract: Laser apparatus includes hydrogen or deuterium buffer gas and dispenser reservoirs 6 and 7 containing a hydride or deutride respectively. As gas molecules from the buffer gas are lost within the discharge tube 1 due to trapping and sputtering processes, hydrogen or deuterium is given off from the surfaces of the reservoirs 6 and 7 to maintain the vapour pressure within the discharge tube 1 at a substantially constant level. There is dynamic equilibrium between reservoir material and the buffer gas, and the pressure of the latter is less than one torr. The laser apparatus operates in a "sealed- off" mode, that is without requiring that buffer gas be flowed throught it. The active medium is a metallic vapour e.g. copper. <IMAGE>
