Title: Flash-free molding of i.c. engine passages
IPC: B29C33/00
Filed: 1990-02-12
Abstract: A method of making a molded plastic component of an 
internal combustion engine. The method disclosed is for 
making a fuel rail (10) and comprises constructing particular 
core pins (20) of the mold with threaded connections that form 
seals between them when they are disposed in proper 
position within the mold cavity for the molding of a fuel 
rail. The core pins serve to form a main fuel passage and 
auxiliary fuel passages which transversely intersect the 
main fuel passage. Each core pin that forms an auxiliary 
fuel passage (14) comprises a screw thread on its inner end 
that threads into a corresponding complementary threaded 
recess in the side of the core pin that forms the main 
fuel passage to create a corresponding seal. This sealing 
prevents any significant flash from forming in the fuel 
rail at the intersection of each auxiliary fuel passage 
with the main fuel passage. After the plastic has been 
molded, the core pins are unthreaded and withdrawn.

Patent EP-0436901-A3 (EP)
Title: Process for preparing a 1,4-diazacycloheptan-2-one with a mixture of alkylated diamines
IPC: C07D243/10
Filed: 1990-12-20
Abstract: A process is disclosed for making a 1,4-diazacycloheptan-2-one from a mixture ('first' mixture) of alkylated 1,3-propanediamines one of which (referred to as the 'target' diamine) has substituents at specifed positions and contains (i) a terminal primary amine group adjacent to a disubstituted C atom (hence, referred to as having a 'hindered' N atom), and (ii) a terminal secondary amine group. The target diamine, other diamines and oligomeric polyamines in the first mixture, are made by alkylating an acyclic ('starting') 1,3-propanediprimaryamine having the hindered N atom. The first mixture of alkylated diamines, preferably containing a major molar proportion of the target diamine relative to any other alkylated diamines, is reductively alkylated, which unexpectedly results in the reductive alkylation of only the unwanted diamines, allowing the target diamine which is not reductively alkylated, to be removed from the mixture of reductively alkylated diamines. Upon cyclization of the target diamine, using the "ketoform reaction", it is essentially quantitatively converted to the 1,4-diazacycloheptan-2-one having an unsubstituted N<4> atom flanked by disubstituted adjacent C atoms. By removing the unwanted components in the reaction mass an essentially pure product of 1,4-diazacycloheptan-2-ones is recovered. Thus, the difficulty of separating the target amine from other close-boiling compounds is avoided. As an alternative, the reductive alkylation step can be bypassed and the first mixture subjected to the ketoform reaction, followed by recovery of the desired product.

IPC: H01L27/12
Filed: 1990-08-14
Abstract: A process of producing an SOI-structured 
semiconductor device substrate, comprising  
bonding polished surfaces of two Si-monocrystal 
wafers (1a, 1b), at least one of which surfaces bears an 
oxide film (1c), and uniformly eliminating part of the 
thickness of one of the wafers (1b) parallel to the 
polished surface, characterised by:  
reducing the diameter of said one wafer (1b) so that 
it is slightly smaller than that of the other wafer (1a), 
thereby exposing an unbonded uniform annular periphery on 
the surface of said other wafer (1a);  
forming, on the surface of said one wafer (1b) and 
said periphery, a material (1d) providing greater 
resistance to polishing than said one wafer (1b); and  
polishing said one wafer (1b).  
     Even when only a few µm thick, the material, e.g. 
SiO₂, provides accurate thickness control of the thin 
film, and thus acts as a polishing guard.

Abstract: A switch activator is described which is a unitary molded 
plastic molded coil spring (22) and a pivot plate (16) which pivots 
to act on a membrane switch (18) when the coil spring buckles 
under load. The buckling of the spring is controlled by 
the relative placement of the axis of the spring and a 
pivot surface around which the top portion of the spring 
pivots as the spring buckles. The cross section of the 
spring member is limited in size so as to prevent the 
forming of a solid column upon compression, while at the 
same time accommodating the needs for molten plastic flow 
in the spring during molding.

Abstract: A method for maintaining mailpiece integrity in a mailing system when
a mechanical module experiences an error. For one category of errors, the
mailing system may automatically recover from the error without operator
intervention. For the remaining category of errors, the mailing system may
recover from the error with minimum operator intervention, that is, the
operator may be required to only remove the error producing mailpiece. A
motion control processor for an error producing mechanical module will report
a fault to its corresponding mailpiece builder task (30) and the error detector
task. Movement of at least the error producing mailpiece shall stop. The fault
will be reported to the mailpiece builder tasks (30) corresponding to the
mechanical modules having no error condition. The mailing system shall
suspend further processing of mailpieces upstream from the error producing
mailpiece. For one category of errors, the mailing system will purge the error
producing mailpiece from the error producing module without operator
intervention. For the remaining category of errors, the operator will be
required to remove at least the error producing mailpiece. State machines
(24) are then selected to perform system wide job recovery.

Patent EP-0780683-A3 (EP)
IPC: G01N25/68
Filed: 1996-12-13
Abstract: Apparatus for dewpoint determination includes an 
elongate mirror or glass plate (10) which is cooled at one end (12), 
or is cooled differentially at opposite ends, so that as 
the mean temperature of the mirror or plate falls, a 
temperature gradient is at the same time established along 
the plate so that as dew starts to form on the plate or 
mirror, it does so as a wave which travels along the plate 
or mirror as cooling progresses. Electro-optical sensing 
means (L,D) senses the passage of the front of this wave past a 
location on the plate or mirror at which a temperature 
sensor (T) is disposed, the temperature sensed just as the dew 
wave front passes corresponding to the dewpoint. In 
variants a temperature sensor is not necessarily located at 
the position of the electro-optical sensing means, but the 
temperature at the location of the electro-optical sensing 
means is calculated from the temperatures at the ends of 
the plate or mirror, and the calculated temperature 
gradient, at the time of passage of the dew wave. In other 
variants the electro-optical sensing means is scanned along 
the plate or mirror and the position of the dew wave front 
determined from the instant during the scan at which the 
front is detected. The invention improves the accuracy of 
dewpoint determination by reducing or eliminating 
uncertainty as to the actual point of commencement of dew 
formation.
