Title: I.c. engine fuel injection valve with valve body and elastic expansion sleeve
Inventor: POTZ DETLEV
IPC: F02M61/18
Filed: 1996-09-12
Abstract: The valve has a valve body 1 and a cup-shaped expansion sleeve 7 of elastic material which is pushed on to the combustion chamber end of the valve body 1 so that it is axially braced against the valve body. The sleeve 7 is then attached to the valve body 1 eg by screwing or welding so that a pressure chamber 23 is formed into which a high-pressure duct 27 opens and which is connectable to an injection chamber 25. The valve body 1 has a conical valve seat region 17 which rests, between injections, under an adjustable pre-tension against a radially-protruding sealing edge 21 on the expansion sleeve 7. Supply of fuel under pressure through duct 27 causes radial expansion of the sleeve 7 so that valve seat 17 and sealing edge 21 separate, allowing fuel to reach the injection chamber 25. In a modification (fig.7), the expansion of the sleeve 7 occurs axially, a conical projection (37) inside the base of the sleeve engaging with the end of the high-pressure duct 27. The invention leads to lower production costs and enables modular construction.

Title: A separator with contra-rotating vortices for an i.c engine
Inventor: HUTCHINS WILLIAM RICHARD
IPC: F01M13/04
Filed: 1996-11-29
Abstract: A separator 8 for the separation of liquid from gas comprises two or more interconnected part cylindrical chambers connected between a flow inlet and a flow outlet such that contra-rotating vortices are produced in adjacent chambers when a liquid and gas mixture is passed therethrough. The change in direction of the flow when passing from one chamber to the next in combination with the centrifugal effect of the vortices aids the separation of the denser liquid from the less dense gas. The separator 8 may have three interconnected part cylindrical chambers arranged in series, or may be in the form of two sets of chambers 12, 14 and 12', 14' arranged in series, with each set sharing a central outlet chamber 16. Flow through entry passages 28, 25, 22 and 30, 26, 24 into the chambers 12, 14, 16 and 12', 14', 16 respectively produces contra-rotating vortices in adjacent chambers. The separator 8 may be used in an internal combustion engine to separate oil from air in breather gases, any oil separated from the air flow collecting on the walls 27 separating the chambers 12, 12', 14, 14', 16 and dripping onto the baffle plate (7, fig 3) before draining back to the cylinder head (1, fig 1). The separator 8 may be provided with weirs 18A, 18 and 20, 20A proximate the entry passages 25, 22 and 26, 24 to prevent the flow of liquid along the ceiling (38, fig 3) of the chambers.

Patent GB-2322314-A (GB)
Title: Centrifugal separator
Inventor: COX IAN MALCOLM
IPC: B04B9/06
Filed: 1997-02-21
Abstract: A centrifugal separator for non-cohesive particulates, such as are found in transmission oils and hydraulic liquids, consists of a housing 11 enclosing a vertical spindle 16 on which spins a liquid reaction driven rotor container 20. The container is divided internally by inwardly extending partition wall 35 into separate outflow chambers 36 and 37. Non-cohesive particulates which separate from the liquid, and are held against the peripheral side wall 24 1  by centrifugal force during rotation, slump therefrom in the absence of rotation and risk forming a slurry that gets carried to the outflow chamber. Barrier means 140 consists of a upwardly extending, outwardly inclined barrier wall 141 forming a contaminant retention region 144 with a restricted neck 143 defined by the separation of the barrier wall edge 142 from the side wall, that permits deposits on the barrier wall to carry to the peripheral side wall and spread across it during rotation, does not interfere with slumping absent rotation and inhibits the slumped material from being washed into the outflow before rotation recommences.

Patent GB-2326284-A (GB)
Title: Wide bandwidth antenna arrays
Inventor: HILL DAVID ROY
IPC: H01Q9/26
Filed: 1997-06-11
Abstract: The invention is a skewed Log Periodic Dipole Array (LPDA) which, when used as the element in a linear or planar array, serves to remove the element spacing restriction and hence eliminates the grating lobe problem. The skewed form of the device has all dipoles greater in length than the shortest one 10, i.e. the highest frequency one, skewed such that they are "Z" or "C" shaped. Of particular interest is the case when the angle between the end and centre segments of the "Z" dipole is 90 degrees. The skewed LPDA has a constant width 2y equal to the length of the highest frequency dipole. Mathematical modelling has established that planar and linear arrays of skewed LPDA's can provide grating lobe free performance over at least an octave. The upper frequency limit of operation is governed largely by the accuracy with which the feed point can be constructed.
Patent GB-2312890-A (GB)
Title: A palette
Inventor: MAPLE PETER MARK
IPC: B65D19/00
Filed: 1996-02-08
Abstract: The invention relates to a pallet (1) comprising a major surface (2), feet (3) recessed from the major surface (2), and drainage means (4), the arrangement being such that the drainage means (4) permit drainage from the major surface (2) into the feet (3). The pallet is made from plastic, in the embodiment a multi-, suitably dual-skin plastic and the major surface (2) in use supports cargo (not shown). Each foot (3) has a ledge (9) for receiving a bottom edge (10) of a sleeve, and, at a corner foot, the ledge (9) extends around two external sides of the foot. The ledge (9) is continuous or discontinuous and provides a planar support surface on which the sleeve is received so that the whole of the bottom edge of the sleeve is uniformly received and supported by the ledge (9). This is important because in this way no part of the bottom (10) of the sleeve (7) is unsupported, which means that the sleeve (7) is undeformed in use under vertical load.
