Title: Insulated steel grillage for road, railway, and airport construction and the like
Inventor: PONTYNEN ESKO
IPC: E01B1/00
Filed: 1989-04-07
Granted: 1992-08-18
Abstract: ABSTRACT OF THE DISCLOSURE   Longitudinally-positioned sheets of corrugated steel (1) are joined at right-angles to latitudinally-positioned sheets of corrugated steel (2) using rivets or screws (3) thus creating a grillage-like structure.  The cavities between the corrugations are filled with heat-insulating material (4) such as polystyre or peat.  In road and airport construction the grillage structure will then be covered by a layer of stabilised or non-stabilised crushed aggregate or chips (5) and a further surface layer of asphalt or concrete pavement.  In railroad construction rails may be fixed directly to the top layer of corrugated steel. Filling with polystyrene will permit the grillage structure to be used directly on lakes and swamps as a foundation for floating airstrips either for civil light aircraft or emergency military use, or for constructing pontoon bridges. Polystyrene-filled grillage can also be adapted, by means of a suitably designe bows, stern and sides together with the addition of an outboard motor, for emergency use as a ferry.  Polystyrene-filled grillage can also be used to build pontoon jetties.

Title: Method and equipment for evaluating the flexibility of a cervical portion of a human spine
Inventor: GRACOVETSKY SERGE
IPC: A61B5/11
Filed: 1989-04-28
Granted: 1993-12-28
Abstract: ABSTRACT OF THE DISCLOSURE     A method and equipment are disclosed,  which are especially designed for evaluating the flexibility of the cervical portion of the spine of a patient in any plane and thus detecting any discrepancy from a "normal" response that would help a medical doctor to establish and/or confirm a cervical pain diagnosis.  The equipement comprises a string of separate, dot-sized skin-markers which preferably consist of small LEDs fired under computer control, that are fixed onto the skin of the patient's back in the midline of his spine from at least thoracic vertebra T5 up to the skull.  Other skin markers are detachably fixed in a bilateral and symmetrical manner on the skin of the patient's back on the crests of his scapulae, and on the rear of the patient's head.  A visualization equipment which preferably comprises a pair of cameras spaced apart from each other, is used to track, monitor and record the relative positions of all of the skin-markers on the back,  neck and head of the patient as he flexes his neck in his  sagittal and/or frontal plane(s).  The so recorded position of the skin-markers are processed to measure the scapula motion and evaluate its contribution to the neck motion; to measure the cervical spine motion; and to extract from the last measurement the intersegment and segmental mobilities of the cervical spine.          All of these data as well as others such as the neck velocity, the percentage of cervical elongation, etc..., can then be compared with each other and with results obtained from  a  group of  "normal"  patients,  to determine any discrepancy or singularity.

Abstract: A method of preparing a substituted derivative of sphingosine comprising the steps of reducing serine methyl ester by a hydride reagent to form an aldehyde or aldehyde derivative, adding acetylide anions to the aldehyde to form an erythro-isomer of propargyl alcohol and inverting the propargyl alcohol by S N2 inversion to form a threo-isomer.  Either isomer can then be de-protected to form an alkyne with a 2-amino-propane 1,3 diol head group; this alkyne can be reduced to form sphingosine or a sphingosine derivative which can be functionalized at the 4 and 5 positions to form a substituted derivative of sphingosine.

Abstract: There is disclosed synthesis of CH3OH from carbon monoxide and hydrogen using an extremely active homogeneous catalyst for methanol synthesis directly from synthesis gas.  The catalyst operates preferably between 100-150°C and preferably at 100-150 psia synthesis gas to produce methanol.  Use can be made of syngas mixtures which contain considerable quantities of other gases, such as nitrogen, methane or excess hydrogen. The catalyst is composed of two components: (a) a transition metal carbonyl complex and (b) an alkoxide component.  In the simplest formulation, component (a) is a complex of nickel tetracarbonyl and component (b) is methoxide (CH30?), both being dissolved in a methanol solvent system.  The presence of a co-solvent such as p-dioxane, THF, polyalcohols, ethers, hydrocarbons, and crown ethers accelerates the methanol synthesis reaction.

Abstract: Title Method of Manufacture of Creamy Havarti Style Cheese ABSTRACT OF THE DISCLOSURE    A method of manufacturing a specialty cheese according to the teachings of the present invention is disclosed relating to the manufacture of a creamy Havarti style cheese.  According to the present invention, to reduce the moisture content, the curd is cooked at a temperature exceeding the recommended maximum temperature for optimum acid production for a mesophile culture and specifically at a temperature in the range of 104 to 106°F for a cooking time in the range of one hour for retarding the culture growth to restrict the number of cells to reduce the bitterness in the cheese and for modifying the enzymatic activity of the starter organisms while still achieving acceptable acid production.  Further, according to the present invention, the change of balance between the enzymatic activities previously accomplished by chilling the curd with a water bath treatment is accomplished by curing the cheese in a first curing regimen at a temperature in the range of 55 to 65°F for in the range of 1 to 3 weeks to modify the enzymatic activities to favor the leuconostoc organisms responsible for flavor development and then by curing the cheese in a second curing regimen at a temperature in the range of 40 to 45°F.  Elimination of the water bath treatment saves water, water disposal and time, and reduces the risk of product contamination.
