Title: Installation of piles for offshore structures
Inventor: HOULAHAN GERARD
IPC: E02D5/62
Filed: 1985-10-11
Abstract: A method of installing a pile for an offshore structure consists of grooving the soil, during pile driving, by wedge shaped grooving tools (16, 17 and 18) on the external surface of a pile (14), then injecting grout through grouting ports (e.g. 19) into the grooves so formed, thus to ensure a uniform flow of good quality grout along the wall of the pile. Although the full circumference of the pile surface may not be in contact with grout, the installation of a long pile grouted in this manner should produce confidence of adequate grouting, since the grooves define paths of reduced resistance to grout flow, and provide a defined minimum area of bond between the pile and the grout. The grooves may alternatively be formed by waterjetting. <IMAGE>

Title: Rotary severing device
Inventor: BAIN RONALD WILLIAM CALDER
IPC: G21C19/36
Filed: 1986-10-06
Abstract: The device is used to sever elongate articles, such as nuclear fuel pins, into shorter lengths to expose the fuel inside the fuel pin and hence facilitate dissolution. The fuel pins 68 are fed through apertures 64, 66 in supporting members 62, 60 and urged against a rotatably driven hub 10 having circumferentially elongated holes 16, 22 which are provided with cutting edges by a blade 54. When the hub 10 rotates into a position such that an aperture 66, 64 registers with a hole 16, 22 in the hub 10, the fuel pin in that aperture 66, 64 passes through the hole 16, 22 until arrested by a stop 24. Further rotation of the hub 10 causes the blade 54 to sever the fuel pin. The holes 16, 22 are flared to allow the severed portions of fuel pin to fall out of the holes 16, 22 into a container. One, or more than two, cutting holes may be provided. <IMAGE>

Title: Crankcase compression four-stroke engine
Inventor: FRY PATRICK FREDERICK
IPC: F02B75/22
Filed: 1986-11-03
Abstract: Air or mixture enters a sealed crankcase 4 through a one way valve mechanism 5 and as the pistons 1 and 2 move down, the volume of the crankcase 4 is reduced and thus the pressure increased. This pressurised air or mixture is fed via ducts 13 to the cylinder which is on its induction stroke. The engine's characteristics may be varied by adjusting the crankcase pressure increase. This can be controlled by connecting separate chambers (10, Fig. 3) the crankcase 4 with valve mechanisms (11) or using a piston (12) in a bore off the crankcase which can be moved in and out to adjust the volume of the crankcase. The charge in the crankcase may be cooled by spraying water into the crankcase or the charge transfer ducts 13 or a heat exchanger may cool the charge. The engine may additionally have a supercharger. <IMAGE>

Title: Electric switches
Inventor: FLETCHER STEPHEN JOHN HENRY
IPC: H01H17/22
Filed: 1986-11-26
Abstract: An electric switch comprises a contact mechanism (10), comprising a pair of fixed contacts (16, 18), a moving contact member (28), and spring means, afforded by compression springs (34, 36), engaging the contact member (28) to close the contacts. The switch also comprises an operating mechanism (12) mounted in a central, circular aperture (38), which may be rotated about its longitudinal axis by a pull cord (42), and returned to a rest position by an 38 extensible member (46). The operating mechanism (12) carries an actuator mechanism (14), comprising a spindle (52), and an actuator member (54) which may be mounted on the spindle (52) in one of two orientations. By pulling of the cord (42) the spindle is caused to rotate by drive means (62) operative between the operating mechanism (12) and the actuator member (14), to rotate the actuator member (54) relative to the moving contact (28). The contacts may be retained set by a ratchet (60/62) or retractive by the spring (46). On opening the contact mechanism, the contact member (28) pivots about a knife edge 30 to open contacts (18, 32). If the latter are welded, then contacts (16, 30) open instead. <IMAGE>
