Title: Method of constructing a submerged tunnel
IPC: E02D29/067
Filed: 1980-02-22
Abstract: A method of, and apparatus for, constructing a submerged tunnel in situ and a submerged tunnel formed thereby has an inverted arch formation to resist upward buoyancy thrust and a sealed chamber unit mounted on the tunnel and longitudinally displaceable along it for servicing the exterior of the tunnel. The tunnel is constructed in situ by progressively lengthening towards each other two tunnel sections (3, 3 min ), which extend in cantilevered manner from opposed base foundations (1 and 2). Each tunnel section has mounted on the free end thereof of an outer chamber unit (13, 13 min ) and an inner chamber unit (6, 6 min ) within the latter of which the free end of the tunnel section is progressively formed and extended. As the tunnel sections (3, 3 min ) are lengthened their associated chamber units (6, 6 min , 13, 13 min ) are displaced longitudinally and sequentially to provide clearance for further lengthening, such displacement may be effected by hydraulic rams (20) or mechanical rack and pinion devices (19) When the tunnel sections 3, 3 min  are sufficiently lengthened the outer chamber units (13, 13 min ) dock and are sealed together at 28, 28 min and a passage opened between those chamber units (13, 13 min ). The inner chamber units (6, 6 min ) are removed from within the combined outer chamber units (13, 13 min ) and a passage is opened between these latter units through which the tunnel sections are extended and connected together to form the continuous tubular tunnel. The submerged depth of the tunnel sections may be controlled during construction by winches and anchorages devices (25, 26 and 27).

Title: Swage-type fitting for non-skived hoses
IPC: F16L33/207
Filed: 1980-03-26
Abstract: A swage-type hose end fitting for attachment to a wire-braid reinforced hose, the end fitting comprising a hollow stem portion (10) for location within the hose bore and a ferrule (11) for swaging onto an end portion (14) of the hose. The ferrule has an annular body which is formed with internal buttresses (21) and a nib (30) for gripping the hose end portion to form a weatherproof seal, and the ferrule also has a flange (29) for locating in a recess (17) of the stem portion ahead of the hose end portion when the ferrule is swaged onto the hose end portion. A first zone of the ferrule includes the buttresses and the first zone separates second and third zones of the ferrule which, respectively, include the flange and the nib. The first zone of the ferrule has an initial outside diameter which is greater than that of the second and third zones so that, when the ferrule is swaged onto the hose end portion, the first zone travels a greater radial distance toward the stem than do the second and third zones and in so doing allows reliable connection between the recess (17) and flange (29). <IMAGE>

Patent GB-2096312-A (GB)
Title: Detecting or measuring movement
IPC: G01P15/16
Filed: 1981-04-08
Abstract: In order to detect when a moving member 1 reaches a pre-determined velocity or has stopped, it has attached to it a strip 2 bearing a series of retro-reflective triangular shapes 2A. Three optical detectors 7A, 7B and 7C view the strip 2 through an optical system 5 and, because of the tapered shape of each triangle, the output from each optical detector, after differentiation, indicates the velocity of movement. A logic circuit 11 provides a "majority decision" indicating whether the outputs from a majority of the detectors 7A, 7B and 7C indicates that the velocity is below a pre-set level. This means that false indications provided when one of the detectors (detector 7C as illustrated) is viewing an area between two of the triangles are ignored. The detection apparatus may be mounted on a vehicle and the strip 2 on a rail. The detectors 7A, 7B and 7C may alternatively be tapered and the shapes 2A in the form of straight lines. <IMAGE>

Title: Method and apparatus for simultaneous measurement of borehole and formation neutron decay-times
IPC: G01V5/10
Filed: 1981-08-14
Abstract: A borehole and earth formations in its vicinity are irradiated with pulsed fast neutrons and during the interval between neutron pulses, capture gamma radiation is measured in at least four, non-overlapping, contiguous time intervals. Count-rates representative of thermal neutron populations in the borehole and the formations are generated during each of the at least four time intervals. A background radiation measurement for correcting the count- rates is preferably also periodically made. The count-rates are combined to derive simultaneously, the formation and borehole components of thermal neutron lifetime which are recorded as a function of a borehole depth.

Title: Turntable mounted elevatable member
Inventor: ARMSTRONG ANTHONY CLUBLEY
IPC: B66F11/04
Filed: 1981-09-08
Abstract: A turntable mounted elevatable member such as a ladder 1 uses a dual concentric ram 7 for elevation thereby providing two independent hydraulic circuits for safety and avoiding the need for mechanical Sons locks. The single point mounting at each end of the ram 7 by self- aligning bearings 8, 9 permits the state movement required for plumbing the ladder of elevation bearing 5 by rams 6A, 6B without the need for the complexity required to control two separate elevation rams during plumbing. The dual ram 7 has a retraction chamber to enable the ladder 1 to be held against lifting due to external influences. Lock valves for the separate chambers of the ram 7 are built into its base. The invention can also be embodied in a turntable mounted elevatable man-carrying platform. <IMAGE>

Title: Containers
Inventor: RAYNER ADRIEN PATRICK
IPC: B65D43/02
Filed: 1981-12-17
Abstract: A paint container has a plastics lid engaged in a metal lever ring of the container body. The lid has a in peripheral flange 15 and a snap-in bead 28 spaced from the flange by the generally cylindrical sealing surface 14 of the lid. In order substantially to reduce pressure differences between the interior and exterior of the container, the bead is segmented and vent formations in the form of ribs or grooves 31 extend between the bead segments and the flange. When the lid is fitted the vent formations provide vent passages enabling equalising gas to flow through the interface between the lid and the lever ring. The passages are such, however, as to be closed off by any paint which attempts to pass through them. <IMAGE>

Title: Making pipe bends
IPC: B21C37/28
Filed: 1982-04-15
Abstract: A method of making pipe bends in one piece directly from a sheet blank comprises deep-drawing the sheet blank to a bent pipe along a curved axis corresponding to the curvature of the pipe bend and trimming the ends of the bent pipe. Preferably, the deep-drawing of the sheet blank is carried out as reversed drawing operation simultaneously in opposite directions. The apparatus for carrying out said method includes a frame, a curved die (2) fixedly mounted in the frame and a curved, hollow punch (3) which is pivotally mounted in the frame. The centre axis of said punch is located on the same circular arc as the centre axis of the die.

Title: Towing apparatus for motor vehicles
Inventor: SEDELMAYER FRANZ X
IPC: B60D1/06
Filed: 1982-08-20
Abstract: A towing apparatus can be attached to a towing vehicle for the purpose of towing away a motor vehicle and comprises an extensible frame (3, 5) supported by at least one pair of wheels, and also a holding fork (9) into whose side holding frames a pair of wheels of a motor vehicle which is to be towed away can be inserted. The holding fork (9) is supported centrally on the frame (3, 5) by means of a spherical holding bearing (7) which permits, during the towing operation, movements of the holding fork (9) about two axes at right angles to one another, while the rotary movement of the holding fork about its longitudinal (pitch) axis is prevented by a supporting bearing (37, 39, 41, 43, 45, 47). The surfaces of the holding frames of the holding fork (9) are thus held at a determined angle to the horizontal during the towing operation. When the towing apparatus is lowered in order to load a motor vehicle onto it, this locking of the spherical bearing (7) is released, so that the surfaces of the holding frames can be laid practically directly on the ground. <IMAGE>
