Abstract: Water heating apparatus by flow of electric current through the water from a set, for example, of eight electrodes whose surface areas for current flow are proportional to the value of two raised to the eight exponents zero to seven, that is 1 to 128. This gives an area range of 1 : 256 which can be switched in binary digital manner automatically by solid state circuitry in response to a temperature window, electric current flow or other indicators. This gives automatic compensation for wide water conductivity ranges and flow rates without any moving parts to give a practical mass-produced industrial or domestic water heater.

Title: Method for feeding fibres to a fibre cutting machine, and fibre cutting machine for implementing such method.
Inventor: PIERRET HUBERT
IPC: D01G1/04
Filed: 1988-09-23
Abstract: A process for feeding fibres towards the fixed and mobile knives of a fibre cutter, such as a flock cutter, is provided which includes preparing a mattress of fibres aligned in a direction which is substantially perpendicular to the vertical plane of the knife so that the mattress of fibres takes the form of a band. The band is conveyed in a step-by-step manner towards the knives while supporting the band adjacent the fixed knife so that its lower face and its lateral side faces are supported by planer support surfaces having a dimension significant in relation to the length of sections of fibres being cut. The step-by-step conveying is effected by bringing the band to a temporary standstill in relation to the support surfaces as the fibres are advanced towards the cutter.

Title: Engine intake system
Inventor: HALL KEITH GORDON
IPC: F02B27/02
Filed: 1988-10-06
Abstract: A compact high inertia engine intake system is described for an internal combustion engine achieving near optimum 
breathing over most of the engine's speed range even with fixed valve timing. The internal combustion engine has two or 
more cylinders with individually tuned intake pipes to each cylinder, characterised in that each pipe carries one or more 
interconnecting ports and valve means for whose operation permits air flow between the ports. Preferably two or more in­
take pipes are brought together to form a cluster which houses the valve means which may be integrated to form a single 
valve within the cluster. The intake pipes for out of phase cylinders act as a plenum for the intake pipe in the induction 
phase when the valve means is open. Pairs of intake pipes can share a single throttle valve adapted to provide an uninter­
rupted passage along the pipe when fully open. In a preferred embodiment the valve means opens in two stages, the first 
stage connects together only the intake pipes whose induction phases do not overlap, and the second stage connects all the 
pipes in the cluster together.

Abstract: In a double-flow exhaust device with a catalyst (3), the two exhaust gas streams (7a, 7b) are first of all brought together so that they are adjacent to one another in a mixing tube (9), and then leave this mixing tube (9) again in tubes (11a, 11b) lying one above the other. These tubes (11a, 11b) lying one above the other open adjacently into a common catalyst housing (3). This arrangement guarantees homogeneous exhaust gas distribution over the catalyst cross-section. A long mixing section is thus not required; furthermore it is sufficient to provide a lambda sensor (13) in only one (11b) of the two tube(s) leading from the mixing tube (9) to the catalyst (3). <IMAGE>

Abstract: This invention relates to a process for preparing polyethylene wax having a narrow molecular weight distribution in a gas phase polymerization reactor. The invention particularly relates to the process of polymerizing ethylene in the presence of a supported metallocene-alumoxane catalyst and hydrogen. The catalyst may be derived from the addition of silica gel containing about 6 to about 20 percent by weight adsorbed water to a trialkylaluminum solution. An alumoxane coated silica gel is formed to which a metallocene may be added and the resulting material dried to free flowing powder. A trimethylaluminum pretreated metallocene may be employed when the trialkylaluminum is selected from the group consisting of triethylaluminum, tripropylaluminum, tri-n-butyl-aluminum, tri-isobutylaluminum, tri(2-methylpentyl)aluminum, trihexylaluminum, tri-n-octylaluminum and tri-n-decylaluminum.

Abstract: A standard reference deformation of a composite material (40) containing a flowable phase (120) and compressible 
inclusions (122), such as prepreg (116), is measured as the deformation whereat the dominant compressive mode of compo­
site deformation changes from that characteristic of compressible inclusion collapse to that characteristic of resin flow, 
termed the optimal consolidation deformation. Establishment of this point permits measurement and correlation of physi­
cally significant composite properties. For example, material properties of such composite materials are measured under a 
compressive loading by an ultrasonic transducer (36) at the optimal consolidation deformation. At this point, normally de­
termined to be the deformation at which the second derivative (134) of compressive displacement falls to about zero, com­
pressible inclusions such as voids (122) are eliminated but the flowable phase has not yet begun to flow significantly so as 
to change the fractions of the phases. This technique is particularly valuable in ultrasonically measuring properties such as 
phase fractions of resin matrix prepreg materials wherein the resin has not been cured and readily flows, and wherein there 
are typically voids that interfere with the measurement of properties.
