Title: Replacing mains
Inventor: WILSON FRANCIS DONALD
IPC: A01N29/00
Filed: 1983-08-30
Abstract: An existing main is replaced or prepared for replacement with a new main by fracturing the existing main and maintaining sufficient clearance through the fractured main for movement therethrough of a new main. The mole or a liner for the fractured main, the liner to serve as a protective sleeve for the new main when the new main is subsequently moved into the liner, which is of steel, is adapted to be inserted into and moved along the existing main 8. The mole has a front portion comprising a head 2 and a cylindrical body portion 3 and a rear portion having clamping means 4 for clamping a new main 13. The head 2 has a cutting face 5 for engaging the internal wall of the existing main so as to cause the wall to fracture as the mole moves therealong. The new main which in use is clamped to the mole is towed along behind the mole to replace the fractured old main. The cutting face 5 comprises cutting edges 6 formed by grinding on high tensile steel cutters 7 which are located in keyways in the head 2. <IMAGE>

Patent GB-2134233-A (GB)
Title: Heat exchange apparatus
Inventor: KIDD ARCHIBALD WATSON
IPC: F24H8/00
Filed: 1984-01-25
Abstract: Condensation from flue gases in a heat exchange apparatus (1) can lead to corrosive solid residue, notably on the base (43) of the casing (3) of the apparatus, thereby shortening the life of the casing (3). In this invention the base (43) slopes continually towards a drain (49) so that corrosive residue does not have time to form. The base (43) is separable from the casing (3) so that it may easily be replaced. Corrosive solid residue may also form if the condensate evaporates and this is discouraged by thermal insulation (57) between the base and the flue gas inlet. <IMAGE>

Title: Multi-port radio frequency networks
Inventor: BELTRAN FERNANDO
IPC: H01Q3/40
Filed: 1985-05-31
Abstract: A network has n first network ports 12 and m second network ports 14, and a pair of identical, independent components 161, 162, each having n first component ports 18 and m second component ports 20. A first set of feed networks 22 each has a first port A coupled to one of the first network ports 12, and a pair of second ports C,D each coupled to a corresponding first port 18 of each component 161, 162; the degree of coupling among the ports of each component and of each feed network are characterised by predetermined scattering coefficient matrices. Similarly a second set of feed networks 24 couple the second component ports 20 to the second network ports 14. As a result, the whole network is characterised by a scattering coefficient matrix, relating the coupling among the network ports, different from the scattering coefficient matrix characterising each component; thus the second network ports have a degree of coupling less than the degree of coupling among the second component ports. The network may be a reciprocal network, such as a power divider/combiner, in either waveguide or strip line, or a non- circular network. <IMAGE>

Title: Linking devices for linking together beds or parts of beds
Inventor: STACE BRAN
IPC: A47C19/02
Filed: 1986-03-06
Abstract: The invention provides a device (3) for linking together twin beds (1 and 2) or the separately made top and bottom parts of a double bed. The device has attachment parts (4 and 5), for permanent attachment to the beds or bed parts, and a link (6) which comprises rigid parts hinged together, or is made flexible in some other manner. The device enables the beds or bed parts to be swung apart (as for bedmaking or cleaning) unless they are restrained from doing so by a second linking device at the opposite end or side of the bed. The device may be such as to be movable between a linking state, in which it secures the beds or parts together, and a release state in which it does not. Thus, one end of the link may be pivoted to one attachment part (4) about a horizontal axis, while the other hand has a slot for hooking onto a headed pin (9) on the other attachment part (5). <IMAGE>

IPC: B29C48/90
Filed: 1986-05-29
Abstract: Method of forming an extrudable material into a secondary shape of part or predominantly linear cross-section from a primary shape of predominantly non-linear cross-section which comprises passing extrudable material through a contoured die wherein a slit is made in the material to form two initially adjacent ends which are separated on passage through the die as the material is formed about a forming block towards an exit of part or predominantly linear cross-section. Die apparatus useful in this method comprises an inlet (13) of predominantly non-linear cross-section, a forming block (4) extending through the die, an exit of part or predominantly linear cross-section and slitting means (5) to form a slit separating edges in extrudable material passed through the inlet. Although it is preferred to extrude fine-particle size cementitious compositions, the process and apparatus may be used for any material capable of extrusion. One application for extrusions obtained is in the manufacture of skirting boards.

Title: A clutch shift mechanism
Inventor: KNORR VOLKER
IPC: F16C25/08
Filed: 1987-10-07
Abstract: A shift mechanism for engaging and disengaging clutches comprises an axially movable clutch sleeve (1) which is positively connected to at least one of the two halves thereof. The motion for engaging and disengaging the clutch is imparted to the sleeve (1) by way of a shift fork (16) whose two arms engage around the sleeve (1). A rolling bearing (21, 35, 37) between the shift fork (16) and the sleeve (1) provides a rotary connection between the two fork arms (16a, 16b) and the sleeve (1). The rolling bearing (21) is so preloaded that both its races are loaded continuously by way of its rolling members, to obviate sliding between the latter races and the rolling members upon engagement of the clutch - i.e., during the initial movement of the sleeve (1). <IMAGE>
