Title: Procedure for equilibrium of the ph value of fresh meat
Inventor: AEMIG RENE
IPC: A23L13/70
Filed: 1991-07-03
Abstract: Vesten AG, Stansstaderstrasse 51, CH-6370 Stans              19 Summary The present invention pertains to a process for the equilibration of the pH value of fresh meat, particularly that of oxen, pigs, fowl, lamb, and game.  Freshly butchered meat is divided into individual meat pieces and layered without gaps in a container, then onto the stratified meat pieces an external pressure is applied so that anaerobic storage conditions occur within the stratified meat pieces and between them, and on the basis of the internal pressure produced, osmosis takes place, whereby a storage life of at least seven days results at a cooling temperature between  -1°C and approximately +2°C.

Title: Azeotropic mixture of hydrogen fluoride and 1,1,1-trifluoro-2-chloroethane and process for purification of 1,1,1-trifluoro-2-chloroethane
Inventor: TSUDA TAKEHIDE
IPC: C07C19/12
Filed: 1992-04-14
Abstract: The present invention is directed to an azeotropic mixture comprising hydrogen fluoride and 1,1,1-trifluoro-2-chloroethane. A mixture comprising hydrogen fluoride and 1,1,1-trifluoro-2-chloroethane is phase separated when it is cooled to a temperature below 7°C. 1,1,1-Trifluoro-2-chloroethane is purified effectively from the mixture by cooling the mixture to form an upper liquid phase and lower liquid phase and distilling the lower liquid phase so that the hydrogen fluoride is removed as an azeotropic distillate and 1,1,1-trifluoro-2-chloroethane substantially free from hydrogen fluoride is obtained as a bottom product. The 1,1,1-trifluoro-2-chloroethane obtained can be used as a cooling medium and as a raw material in the preparation of 1,1,1,2-tetrafluoroethane and trifluoroethanol.

Patent CA-2072228-A1 (CA)
Inventor: BARR JOHN D
IPC: E21B47/022
Filed: 1992-06-24
Abstract: A system for maintaining a downhole instrumentation package in a roll stabilised orientation with respect to a drill string comprises an instrument carrier which is mounted within a drill collar for rotation about the longitudinal axis of the collar. An impeller is mounted on the instrument carrier so as to rotate the carrier relatively to the drill collar as a result of the flow of drilling fluid along the drill collar during drilling. The torque transmitted to the instrument carrier is controlled, in response to signals from sensors in the carrier which respond to the rotational orientation of the carrier, and input signals indicating the required roll angle of the carrier, so as to rotate the carrier in the opposite direction to the drill collar and at the same speed, so as to maintain the carrier non-rotating in space and hence roll stabilised.  The torque may be controlled by controlling a variable coupling between the impeller and the carrier and/or by controlling a brake between the carrier and the drill collar.

Title: Real time transformation between colour spaces
Inventor: REED ALASTAIR M
IPC: G06T1/00
Filed: 1991-06-03
Abstract: A method of transforming three independent vectors, which describe a colour, in an original vector space to three independent and one or more dependent vectors in an image vector space, in real time, comprises the steps of providing a look-up table containing original vector space input data and in which image vector space output data, in the form only of three independent vectors have been processed, ahead of time, into image vector space output data comprising modified three independent vectors and one or more dependent vectors, from which the required image vector space output data can be directly obtained. The original vector space vectors are input into the look-up table to obtain the image vector space vectors. The method also provides transforming three independent and one or more dependent vectors, which describe a colour, in an original vector space to three independent vectors in an image vector space, which comprise the steps of resolving the set of independent and dependent original vector space vectors into a reduced set of three independent vectors only and inputting the reduced set of three independent vectors into a three-dimensional look-up table containing three-dimensional original vector space input data and three-dimensional image vector space output data to obtain the three independent vectors in the image vector space.

Abstract: TITLE OF THE INVENTION PROTEINS FOR INHIBITING ADHESION OF PLATELETS TO COLLAGEN            ABSTRACT OF THE DISCLOSURE        The invention comprises proteinaceous substances isolated from crude Ornithodoros moubata extract which inhibit adhesion of platelets to collagen.  These substances do not inhibit platelet adhesion to fibrinogen, and are therefore particularly useful for inhibiting adhesion of platelets to collagen when simultaneous inhibition of platelet adhesion to fibrinogen is undesired.  They are particularly useful in the prevention, prophylaxis, therapy and treatment of thrombotic diseases.

Title: Play House for Use with Construction Toy Blocks
Inventor: BERTRAND VICTOR J
IPC: A63H33/04
Filed: 1993-02-02
Abstract: A play house for use by children to play with dolls or toy figurines. It has a base, a plurality of lateral walls and a roof which altogether define an openable enclosure externally shaped as a house. It also has one or more floor members within the enclosure, each of which has an upper surface provided with a plurality of identical connecting elements, preferably in the form of cylindrical studs, that extend upwardly therefrom. The connecting elements are sized and positioned to fit into, and retain construction toy blocks capable of being assembled with other construction toy blocks provided with the same connecting elements. Advantageously, the floor members are detachably mounted within the enclosure to allow the construction toy blocks to be assembled therewith outside the enclosure. This feature makes the play house easier to play with, as the child may remove the floor member, then build easily on it with the construction toy blocks, and finally reinsert the floor member with the built structure into the play house. This also makes it possible to easily interchange some already built floor members, if the child wants to interchange some of the rooms or pieces of furniture decorating the same, without having to dismantle them and construct them again.
