Abstract: An improved apparatus and method of  sliding window construction  are  disclosed.    When  moving  in  an  open position, a sash member is guided for movement in a first plane generally parallel to the window frame opening.  When moving  toward closure,  the  sash  is guided by  rotatable glide members  that  simultaneously  transversely move  all four corners of the sash into closure under cam action of the  glides,  to  uniformly  compress  a  weatherstrip  seal around the entire perimeter of the sash.   The transverse movement between open and closed positions can be performed in a manner such that the general plane of the sash remains parallel  to  the  first  plane  throughout  the  transverse movement  phase.     Means  are  provided  for  retainably maintaining  the  sash  at  discrete  positions  along  the transverse path of the sash during closure.

Title: Process for the production of a vegetable-oil product
Inventor: LAIHO STIVEN
IPC: C11B1/10
Filed: 1990-04-30
Abstract: Abstract The invention relates to a process for the preparation of a vegetable-oil product from oilseed, such as rapeseed, and to the product obtained by the process. In the process the seed is comminuted, possibly heat-treated, and slurried in water. According to the invention, an enzyme is added to this slurry, the purpose of the enzyme being to retain in the aqueous phase the phosphatides present in the seed, while the oil separates to form a separate phase of its own, which is separated mechan-ically by centrifugation, for example. The obtained crude vege-table oil, which does not contain organic solvent residues and is substantially devoid of phosphatides, is refined physically to produce a final product, the refining comprising a treat-ment with an adsorption agent and/or a deodorization.

Patent CA-2028311-A1 (CA)
IPC: H01P1/18
Filed: 1990-10-23
Abstract: ABSTRACT          An electrically controlled RF phase shifter having an active medium formed from a ceramic material the permittivity of which may be varied by varying the strength of an electric field in which it is immersed.  The phase shifter includes the ceramic material having electrodes mounted thereon that are connected to an adjustable d-c voltage source.  The phase shifter may be placed in an RF transmission line that includes appropriate input and output impedance matching devices such as quarter-wave transformers.  The phase of the RF power exiting the phase shifter will depend on the effective electrical length of the material in the active medium.  Because changes in the permittivity of the material will produce corresponding changes in the electrical length of the material, changes in the phase of the RF power transmitted therein will be produced.  The quarter-wave transformers may also be made of a similar adjustable permittivity material.  Control voltages applied to the transformers are used to adjust the amount of output power.  An interdigitated electrode is used to reduce the amount of voltage needed to operate the phase shifter.  The phase shifter may be embedded as part of a microwave integrated circuit.

Abstract: A yeast cell, preferably Saccharomyces cerevisiae, which contains a functional stable recombinant DNA sequence that does not allow for the encoding of a negative regulator of phospholipid biosynthesis therein and which has multiple copies of an INO1 gene. In a preferred embodiment, the recombinant DNA sequence is an OPI1 gene deletion which results in the deregulation of inositol or inositol-containing metabolites such as inositol-1-phosphate synthase. Moreover, there is a method for obtaining inositol, inositol-containing metabolites or phospholipids such as myo-inositol or inositol-1-phosphate. The method comprises the steps of genetically engineering a stable yeast cell, preferably Saccharomyces cerevisiae, to continually produce inositol, inositol-containing metabolites or phospholipids. Additionally, them is the step of then generating the inositol, inositol-containing metabolites or phospholipids. In a preferred embodiment, the genetically engineering step includes the step of altering the negative regulatory step involved in phospholipid biosynthesis to overproduce inositol, inositol-containing metabolites or phospholipids such as myo-inositol.
