Abstract: An automative vehicle having a fluid-operated, four wheel steering system for steering not only the front wheel pair (1), but also the rear wheel pair (4) as a function of the amount of turn of the front wheel pair (1) with respect to the direction of straightforward run of the vehicle. The system makes use of a front cylinder (16) operatively associated with a steering gear assembly and a rear cylinder (27) operated by a fluid medium supplied from the front cylinder (16) for steering the rear wheel pair (4). In order for the steering system to be responsive to the vehicle running speed thereby to control the amount of turn of the rear wheel pair (4) appropriate for a particular range of vehicle running speed, a device (46) is provided for accommodating a portion of the fluid medium to be sup­plied to the rear cylinder (27) when the pressure of the fluid medium increases to a value higher than a predetermined pressure. Increase of the fluid pressure over the pre­determined value takes place when the steering wheel (2b) is turned during the low speed run of the vehicle.

Abstract: Cell surface gangliosides are presumed to play a role in cell growth and differentiation. Using monoclonal antibodies directed against G D3 , a disialoganglioside expressed predominantly by cells of neuroectodermal origin, we have found that G D3  is expressed by a subpopulation of cells of the immune system including: a) fetal thymocytes in subcortical regions and near vessels, 2) lymph node lymphocytes in interfollicular areas and near vessels, and 3) a small subset of T cells in the peripheral blood. Mouse monoclonal antibodies (two IgGs, one IgM and F(abʹ)₂ fragments) reacting with G D3  were found to stimulate proliferation of T cells derived from peripheral blood. Proliferation induced by binding to G D3  could be augmented by exogenous IL-2, PMA, PHA or Protein A.

Abstract: An extrusion die for producing hollow extrusions from material which is difficult to solidify quickly eg chocolate, comprises an outer die part (l3) secured to the end of a supply pipe (l2). The outer die part (l3) has a central aperture (l6) within which an inner die part having a multiplicity of spaced air injectors (l7) is provided. During extrusion, chocolate is forced through the apertures (l6) and surrounds the injectors (l7) to produce an extrusion having a plurality of longitudinal passages therein. A fluid, e.g. air, is passed through the injectors (l7) and into the longitudinal passages to prevent collapse of the passages before the chocolate has set.

Abstract: Swim goggles 10 have a pair of eye pieces 11,12, each eye piece having a lens 17 with an essentially rigid peripheral frame 18. Each eye piece has a seal assembly 23 which includes a seal holder 28 and a seal gasket 30. The seal holder 28 is secured to the frame 18 and has a pair of spaced flanges 41,42 extending in a direction generally away from the respective lens 17. Space between the flanges of the seal holder provides a groove 58 extending around the eye piece and the seal holder is resiliently deformable but relatively stiff. The seal gasket 30 is fitted within the groove between the flanges 41,42 and has an outer face 60 standing clear of the flanges to contact the wearer's face. The seal gasket 30 is resiliently deformable and softer than the seal holder 28 to provide a secure but comfortable seal with the wearer's face. Selection of the relative resiliences of the seal holder 28 and seal gasket 30 permits accommodation to a wide variety of faces and extends use of the goggles. A face mask with a single lens provided with a seal assembly as above is an alternative.

Abstract: A high pressure, high throughput, single wafer, semiconductor processing reactor (10) is disclosed which is capable of thermal CVD, plasma-enhanced CVD, plasma-assisted etchback, plasma self-cleaning, and deposition topography modification by sputtering, either separately or as part of in-situ multiple step processing. The reactor includes cooperating arrays of interdigitated susceptor (16) and wafer fingers (20) which collectively remove the wafer (15) from a robot transfer blade (24) and position the wafer with variable, controlled, close parallel spacing between the wafer and the chamber gas inlet manifold (26) then return the wafer to the blade. A combined RF/gas feed-through device (36) protects against process gas leaks and applies RF energy to the gas inlet manifold without internal breakdown or deposition of the gas. The gas inlet manifold (26) is adapted for providing uniform gas flow over the wafer. Temperature-controlled internal and external manifold surfaces suppress condensation, premature reactions and decomposition and deposition on the external surfaces. The reactor also incorporates a uniform radial pumping gas system which enables uniform reactant gas flow across the wafer and directs purge gas flow downwardly and upwardly toward the periphery of the wafer for sweeping exhaust fases radially away from the wafer to prevent deposition outside the wafer and keep the chamber clean. The reactor provides uniform processing over a wide range of pressure including very high pressures. A low temperature CVD process for forming a highly conformal layer of silicon dioxide is also disclosed. The process uses very high chamber   pressure and low temperature, and TEOS and ozone reactants. The low temperature CVD silicon dioxide deposition step is particularly useful for planarizing underlying stepped dielectric layers, either alone on in conjunction with a subsequent isotropic etch. A preferred in-situ multiple-step process for forming a planarized silicon dioxide layer uses (1) high rate silicon dioxide deposition at a low temperature and high pressure followed by (2) the deposition of the conformal silicon dioxide layer also at high pressure and low temperature, followed by (3) a high rate isotropic etch, preferably at low temperature and high pressure in the same reactor used for the two oxide deposition steps. Various combinations of the steps are disclosed for different applications, as is a preferred reactor self-cleaning step.

Abstract: In a piston machine, in particular an internal combustion engine, in which the cylinder liners comprise an external supporting section and a wearing section forming a piston ring sliding surface accommodated inside the supporting section, the sliding surface is designed in such a way that it forms as optimum a friction pairing as possible in the fluid friction with the respective piston rings, account being taken of the ease of repair which is particularly important in ship operation. To this end interconnecting grooves and holes, fillable with lubricating oil, are provided in the supporting section and in the wearing section accommodated inside the latter. Helical grooves with opposing pitch are made on the facing surfaces of the supporting and wearing sections. In this way the division of a cylinder liner into a supporting section and, from the friction point of view, optimally matched inner section is advantageously combined with technically advanced cylinder lubrication and cooling. <IMAGE>
