Patent GB-2173494-A (GB)
Title: Stable nitrate/slurry explosives
Inventor: OWEN II JAMES HERMAN
IPC: C06B47/14
Filed: 1986-02-21
Abstract: Explosives that are sensitized blends of inorganic nitrate. e.g., AN, particles, such as AN or ANFO prills, and an aqueous slurry comprising a thickened aqueous solution of an inorganic oxidizing salt, preferably AN, are rendered storage-stable by keeping the slurry's water content low enough, and its viscosity high enough, that the slurry is water-retentive. Water immobilization in the slurry, a requirement for storage stability, is achieved despite the slurry's flowable consistency at the time of blending. A blend containing about 25% slurry or less, is essentially in the form of a granular mass of free-flowing, high-density, slurry-bearing prills, and the slurry is sensitizable by the prills alone. As the slurry content exceeds about 25%, the blend takes on the characteristics of a thick slurry, requiring a supplemental sensitizer in the slurry perse. Slurries containing a nitrogen-base salt of an inorganic oxidizing acid, preferably monomethylamine nitrate, are preferred because this additive affords a saturated solution with lower water content, and also can act as a sensitizer.

Title: Rotary cultivator
Inventor: DICK ADRIAN
IPC: A01B49/06
Filed: 1986-06-23
Abstract: An agricultural machine comprises a rotatable transverse assembly and a plurality of agricultural tools connected to the support assembly to lift and project soil forwardly thereby to work the soil in a continuous path parallel to the direction of movement of the machine.

One function is to prepare a series of continuous parallel rows of seed beds and to deposit seeds without substantially disturbing the ground between the rows. Another function is to stubble mulch a field or paddock after a crop has been harvested so that the mulch is mixed with the upper layer of the soil. The rotary cultivator assembly 50 may be preceded by a disc coulter assembly 30 and may be followed by a seeder assemby 70 and a plurality of pressing wheels 91 at the rear. <IMAGE>

Title: Production of pharmaceutical unit dosage forms
Inventor: KHAN FA EZ
IPC: A61K9/16
Filed: 1986-07-03
Abstract: A method for the production of composite dosage units, such as granules or tablets, containing one or more medicaments comprises the steps of (1) preparing as a workable paste, a first mixture of the medicament, a disintegrant and a water-protective agent such as light oil or isopropyl alcohol effective to prevent absorbtion of water by the mixture, (2) preparing also as a workable paste, a mixture of a carrier material such as micro-crystalline cellulose and water, (3) mixing the two pastes to form a heterogenous mixture, (4) forming this mixture into a shaped body such as an extruded rod or a moulded tablet, and (5) evaporating the protective agent from that body. The rod may be broken into identical lengths and treated to round off the ends. The dosage units are more quickly disintegrated and absorbed in gastric fluid, than convential tablets. <IMAGE>

Patent GB-2186043-A (GB)
Title: Hydraulic collet-type connector
Inventor: JENNINGS CHARLES EDWARD
IPC: E21B33/038
Filed: 1986-12-23
Abstract: The collect-type connector (10) comprising an upper body member (20) having a plurality of collet segments (52), a cam ring (64) movable relative to the upper body member (20) to move said collet segments (52) into a detachable connection of the connector to a subsea wellhead (14). The cam ring (64) and collet segments (52) have sets of camming surfaces whereby a first set (86, 92) cooperate to move the collet segments (52) initially radially toward the wellhead (14) and whereby a second set (96, 104) serves to urge the collet segments (52) further to clamp the connector (10) to the subsea wellhead (14). When the second set (96, 104) of camming surfaces function, the first set (86, 92) no longer function to rotate the collet segments, thus reducing the power requirement for urging the collet segments (52) into clamping engagement to that for operating one set of camming surfaces at a time. One set (86, 92) of camming surfaces serves to hold the collet segments (52) in a conical orientation to facilitate positioning the connector (10) over the wellhead (14) and, second, together with the complementary ledges (90, 94) to form a load path (arrow 122) between the collet segments (52) and the upper body member so that any load on the connector (10) as it is placed in the wellhead (14) will be transferred to the upper body member. Further, the means for actuating the cam ring (64) are hydraulic cylinders (66) which are mounted for easy removal and replacement, if necessary. <IMAGE>

Title: Compliant link and positioning device for tool on robot arm
Inventor: WILLIAMS ANTHONY MICHAEL
IPC: B23Q33/00
Filed: 1988-05-27
Abstract: A mechanism for coupling a tool G to a robot arm A and for aligning the tool orthogonally with respect to a curved or even double curved work surface S. There is a first compliant arrangement C connected to the robot arm and a second compliant arrangement 20 connected between the first and the tool. The first allows linear displacement of the arm with respect to the tool, e.g. by mutual sliding of cylinders 10, 11 against the bias of spring 14. The second has multiple contact probes 60 extending parallel to the tool allowing relative displacement of the tool until all probes 60 and the tool are in contact with the work surface. This aligns the tool orthogonally to the surface. It is preferred that three probes are provided and there may be a lock 40 to prevent relative displacement of arrangements C, 20, except when one probe and the tool are contacting the surface. Second arrangement 20 is a gimbal device allowing linear and/or rotational movement along or about one or two mutually orthogonal axes. <IMAGE>

Patent GB-2228104-A (GB)
Title: Control of forced flue gas appliance
Inventor: MARSHALL EDWARD TREVOR
IPC: F23N5/18
Filed: 1988-10-20
Abstract: When push switch PB is pressed by the user a control voltage is supplied, via a flow switch 12 located in the flue, in its "no-flow" position, to a relay AR and to a holding relay CR. Activation of AR causes mains electricity to be supplied to a fan 10 to draw gases through the flue. If a timer 14 times out and the flow switch 12 is still in its "no-flow" position the system is turned off. If, on the contrary, switch 12 moves to the "flow" position, then a relay BR maintains energisation of the fan and holds a gas supply valve open. Electricity supply to the fan is now preferably via a choke to lower the fan's speed to a value appropriate for normal running. The gas valve is controlled by a thermocouple located adjacent the main or pilot flame. <IMAGE>
