Title: Wall tie for insulated cavity wall
IPC: E04B1/41
Filed: 1979-10-18
Abstract: A wall tie for use in cavity wall construction is formed from a single length of stainless steel wire and comprises a central stem 10 which is bent over at each end to provide a pair of anchors 12 and 13 which in use are embedded between courses in the wall leafs of a cavity wall. The bent-over portion 14 of the anchor 13 extends back towards the middle of the central stem 10 and is then further bent to form a holding means, such as the ring 15 shown, which can hold a sheet of insulation material in position against a leaf of the cavity wall internally of the cavity wall. The ring 15 may surround the stem 10, as shown, or it may be turned in the opposite direction away from the stem 10 (Figs. 6 to 8 not shown). <IMAGE>
Patent GB-2069170-A (GB)
Title: Crimp sleeve, especially for optical fibre cables
IPC: G02B6/38
Filed: 1980-02-13
Abstract: A composite crimp sleeve has an outer sleeve 41 (e.g. of copper) which is deformable, and an inner sleeve 38 which can undergo a predetermined radially inward deformation. The inner sleeve 38 may be intrinsically incompressible (e.g. a stainless steel tube) but have a plurality of longitudinal slots 52 whose closure on compression provides a predetermined reduction in the circumference of base of sleeve 38. The bore remain substantially round, even though conventional crimping will give the outer sleeve 41 a hexagonal surface. The number and dimensions of the slots may be tailored to apply a desired compression to the outer jacket 12 of an optical fibre 10 without damaging the mono-fibre 16. An uncompressed portion 56 serves as an anchor. An S.M.A. plug may use a crimp sleeve 41, 38 for securing an optical cable and a clamp for accurate positioning of the fibre end face. The sleeves 41, 38 may be combined with other plug components to provide a compact plug with very little of the unsheathed fibre left unclamped. <IMAGE>

Title: Heat exchanger, eg for heating water
IPC: F24H1/24
Filed: 1980-04-17
Abstract: A heat exchanger is formed of a once-flat wall (101) shaped in a spiral and having end caps (C1, C2) so as to form a spiral enclosure for the circulation (arrow A) of one of the fluids between the turns of the wall. The other fluid flows (arrow B) either in a network of tubes integral with the spiral wall (Figs. 1-7), or within the wall itself, this being hollow, and possibly having two internal paths for two different fluids. Welding points (102) cause turbulence in the path(s) in the hollow wall. Discontinuities, e.g. holes, can be formed in the spiral wall to break up the flow in the spiral enclosure. The central space (104) can form a combustion chamber for a burner (106). The path(s) in the hollow wall can be used for heating water while hot gases flow along the axial and spiral paths between the turns of the spiral. <IMAGE>

Title: Articulated Support Roller Assembly for Rotor Journals
IPC: G01M1/04
Filed: 1980-06-05
Abstract: An articulated support roller assembly for rotor journals comprises two sets of rollers (1 0a,b; 20a,b) in each of which the rollers are mounted rotatably on a shaft (12) which includes an eccentric portion (15) between the rollers. The shaft (12) is mounted in a sleeve (16) for rotation or tilting about a transverse axis (11) and the sleeve (16) is mounted rotatably to allow the eccentric portion (15) to be adjusted according to the size of journal to be supported. The construction of the assembly allows for physical articulation of journal during rotation by virtue of mounting of the roller sets about the axes which, in turn, enables cylindrical rollers to be employed thus affording high load capacities. <IMAGE>

Title: Optical proximity fuze
Inventor: LLOYD PETER GREGORY
IPC: F42C13/02
Filed: 1981-10-10
Abstract: A conventional rear-fuzed bomb 10 includes a ground sensing proximity fuze with a plurality of sensors 21 - 23 located in wedge shaped housings attached to a rearwardly tapering portion of the bomb. Each housing is constrained in dimensions such that the thickest part thereof does not substantially increase the overall body dimensions of the bomb. Each ground proximity sensor functions by transmitting pulses of infra-red radiation and timing the return of radiation scattered by the ground and detected in the housing. To obtain maximum sensitivity the housing contains an optical collector formed by a Mangin mirror (Fig 3) or plane mirror and aspheric lens which collector effectively fills the thicker end of the housing, to maximise collection area, and direct the radiation to a detector in the thinner end of the housing. <IMAGE>

Title: Shaft mucker
IPC: E21D1/03
Filed: 1981-10-30
Abstract: A shaft mucker comprises a control cabin 1 carrying a boom 2 which can be luffed by hydraulic rams 4 between a raised horizontal position and a lowered downwardly extending position.

Patent GB-2096758-A (GB)
Title: Heat exchanger
IPC: F28D7/16
Filed: 1982-03-04
Abstract: A heat exchanger comprises a jacket tube (1), housing rings (2, 2a) and covers (6, 6a) at each end of the housing rings. Tie rods (13) hold the parts which form the housing together. A tube nest (15) is connected to two tube plates (17, 17a) within the housing. Inside each cover are a number of parallel grooves (9 to 9c) for the engagement of a partition wall (21) which is connectable to the tube plate. In use, a first heat exchange medium flows from inlet (10) through tubes (16) on the right of partition wall (21) and thence returns through tubes (16) on the left of the partition to outlet (11). A second medium flows from inlet (4) over the tubes to outlet (4a). The tube plates may slide inside the housing to accommodate thermal expansion. <IMAGE>
Patent GB-2101672-A (GB)
Title: Security closure
Inventor: MANDER MICHAEL GEORGE
IPC: E05C9/02
Filed: 1980-04-23
Abstract: A pair of deadlocks 14 and 15 mounted respectively adjacent the top and bottom of a door 10 have their dead bolts 19 connected together by an operating bar 26 so that they can be extended and retracted together by means of a handle 32 of a combined deadlock and latch mechanism 16. A lug 37 on a key-operated dead bolt 35 and a slot 40 in the operating bar 26 form a mechanical interlock which ensures that the dead bolt 35 cannot be extended until the bolts 19 have been extended, and that the dead bolts 19 cannot be retracted unless the bolt 35 is first retracted. Extension of the dead bolts 19 is performed by moving the handle 32 upwardly from a horizontal position, the handle then returning automatically to its horizontal position without retracting the dead bolts 19. Retraction of the dead bolts 19 is achieved by moving the handle downwardly from its horizontal position, which also retracts a latch bolt 41. Such an action of the handle 32 is permitted by lost motion between the handle and the operating bar 26 imparted by a lug 56 which rotates with the handle and an arcuate slot 55 in an operating cam 54 which is coupled to the bar 26. <IMAGE>

Title: Torque measurement
Inventor: BAKER JAMES CHARLES
IPC: G01L3/12
Filed: 1982-08-18
Abstract: In apparatus for measuring torque on a shaft (11), reflectors (12, 13) are fixed at axially spaced positions on the shaft and receive light beams from light sources (1,6) via three-port couplers (4, 9), optical fibres (3, 8) and collimators (5, 10). Pulses of light reflected back from the reflectors (12, 13) are received by light detectors (16, 17) via the optical fibres (3, 8) and the three-port couplers (4, 9). The time intervals between the respective pulses vary with the angular strain and thus the torque on the shaft (11). A microprocessor (18) computes the torque from the time intervals between the pulses and displays it on a display means (19). <IMAGE>
