Patent EP-0178382-A3 (EP)
Title: Pressure-stable drainage mats
IPC: E04D11/00
Filed: 1985-06-19
Abstract: The drainage elements consist of water-permeable thin-layered (e.g. filter nonwoven) materials (8a), on the underside of which distance pieces (8b) made of lightweight building materials (e.g. rigid foam) are adhesively bonded. These distance pieces are attached with appropriate gaps, thus producing so-called longitudinal drainage channels (8c) from one distance piece to another. The distance pieces are U-shaped on their underside, so that the transverse drainage channels (8d) are produced and the longitudinal drainage channels are connected to one another. Half a transverse drainage channel (8e) is formed on one side of the drainage element. If, when laying the individual sections next to one another, the longitudinal drainage channels are to be offset relative to one another, the water can still run off unimpeded. In order to improve the adaptability of the drainage element, the distance pieces are provided at variable distances with laminar incisions - as intended points of fracture (8f). At the two terminal boundary faces of the drainage element, the covering material (8a) of the distance pieces (8b) is provided in each case with overlaps (8g) which prevent the bedding mortar from falling through onto the humidity seal. Drainage elements are used mainly as anti-capillary drainage layer under ceramic outer coverings. <IMAGE>

IPC: H01L31/10
Filed: 1985-10-30
Abstract: A non-evacuated photodiode for detecting far-uv radia­
tion. The photocathode is a cylindrical element surrounded by 
an annular anode. The photocathode is constructed of a metal 
(e.g., nickel) that emits electrons only in response to far-uv ra­
diation of 140 nanometer or shorter wavelengths. A window 
(e.g., magnesium fluoride) is positioned at the entrance to the 
photodiode, to filter out far-uv radiation with wavelengths shor­
ter than about 100 nanometers. The window and photocathode 
material serve to make the photodiode sensitive to radiation in 
a wavelength range no greater than 100 to 140 nanometers. A 
high-temperature perfluoroethylene material is used as an in­
sulating layer for spacing the window from the anode and for 
spacing the anode from the photocathode. The photodiode is 
used in a gas chromatography detector.

Abstract: A die formed cooking utensil (10) for use on a cooking 
heat source has a side wall (11) and a bottom wall (12). The 
bottom wall is provided with a raised area (15) generally 
centred on the centre of the utensil, said raised area having a 
maximum elevation of between 0.17 and 0.25 cm above the 
lowermost plane (14) of the bottom wall when the utensil is 
cold. The bottom wall is deformed to be substantially planar 
when heated to cooking temperature.  
     The raised area may comprise an annular region (15) which 
surrounds a less elevated central region (17) but other configu­
ration of the bottom wall are also possible.

Abstract: A constrained optimization component placement system 
uses wire length as the objective function being minimized and 
uses routing resource congestion to define a constraint func­
tion to be satisfied. A carrier is partitioned into rectangles and 
iterative exchange placement and pin assignment is carried out 
for all components within each rectangle. If the new score us­
ing the constrained optimization function is less than the old 
score, the exchange is accepted, otherwise the exchange is re­
jected. Each rectangle is subsequently partitioned and the 
process repeated until a terminal condition, such as routing 
complete, is achieved.

Abstract: Normally tacky, pressure sensitive adhesive 
compositions comprise one or more polymers having a T g  of 
about 0° C. or less containing at least about 40 weight 
percent polymerized, olefinically unsaturated carboxylic 
acid esters monomers and pendant functional groups attached 
to a polymer backbone and having the formula: 
  
in which R₁ is a divalent organic radical at least 3 
atoms in length, and X is organoacyl or cyano. Such 
polymers have markedly improved cohesive strength 
(shear holding value) with little or no detriment to 
adhesive tack or adhesion (peel resistance), and these 
improvements are realized without the necessity of 
incorporating cross-linking monomers such as N-methylol­
amides or other cross-linking agents. Pressure sensitive 
adhesives, water-based emulsions containing such polymers 
and adhesive articles having at least a portion of one 
surface thereof coated with such adhesive are also 
provided.

Title: A method of analyzing high molecular weight dispersants in motor oils
IPC: G01N33/28
Filed: 1987-08-14
Abstract: A method which involves the isolation, analysis and characterization of dispersants present in motor oils is disclosed. The method is particularly useful in connection with the characterization of high molecular weight polybutenyl succinimide dispersants present in finished motor oils so as to provide detailed information with respect to the starting material reactants needed to synthesize such dispersants. The method involves breaking down complexation present in the oil followed by the isolation of the dispersant from the oil via dialysis. The isolated dispersant in the form of a dialysis residue is then acidified and passed through an ion exchange chromatographic column to adsorb acid materials away from the dispersant. Dispersant content and total carbonyl content can then be determined. The dispersant is then subjected to saponification with sodium hydroxide to provide a hydrocarbyl sodium succinate and a polyamine. The saponified material is subjected to further dialysis to separate it from remaining oil and then further acidified. The acidification results in the formation of a corresponding succinic acid and a dialkyl ester derivative. Procedures such as GPC and VPO determinations can then be carried out. Model reactant components can then be prepared and reacted to determine if the reaction product obtained matches the original dispersant being analyzed.

Abstract: An apparatus (50) for supplying polyphase power to an 
induction coil (62) for magnetically levitating metal to 
be cast comprises an input (52) for connecting the 
apparatus to a source of polyphase AC power and a polyphase 
rectifier (54) for rectifying the AC power. A first 
controller (56) selectably varies the magnitude of RMS 
current supplied to the induction coil by controlling the 
electrical phasing of the rectifier. A polyphase inverter 
(58) operatively associated with the rectifier converts 
the rectified AC power to polyphase AC power and supplies 
the polyphase AC power to the induction coil at a pre­
selected frequency. A second controller (60), independent 
of the first controller, controls the frequency of the AC 
power supplied to the induction coil by controlling the 
electrical phasing of the inverter. The induction coil 
has a plurality of sections (⊘1 to-Ø3), each section being 
wound to provide a phase rotation of a magnetic force 
vector over substantially the entire length of the coil to 
produce a continuous magnetic levitation force.

Abstract: A right angled elbow connector which consists of a 
body (10) carrying a hose connector extension (11) with an 
axial bore (12) extending through it into the body (10). In 
the body (10) has a radial bore (13) into which is brazed a 
spigot (14) carrying a captive nut (15). The nut is a solid 
nut rather than the conventional crimped type of nut. The 
spigot (14) has one or more grooves around its periphery at 
(17) which may optionally be fitted with a washer or circlip 
(18). A ring of brazing material is placed at (20).  
     During brazing the washer or circlip, or the groove 
(17) itself prevents flow of the brazing metal up the spigot 
to the nut. The c-ring is only essential if it is desired 
to braze the spigot in position with the nut uppermost in 
which case the washer or circlip prevents the nut falling 
on to the brazing material.
