Title: Method of producing recombinant dimeric enzyme
Inventor: LONG SUSAN
IPC: C12N1/21
Filed: 1994-11-02
Abstract: This invention relates to a method of producing a recombinant eukaryotic heterodimeric enzyme using a prokaryotic host. The method involves constructing a first DNA vector containing DNA encoding one of the subunits of the dimeric emzyme and then constructing a second DNA vector containing DNA encoding the second subunit of the enzyme. Once the DNA vectors are constructed, they are used to transform a prokaryotic host. The transformed prokaryotic host cell is then cultured under conditions appropriate for the expression of the dimeric enzyme. For example, using the method of the present invention, the heterodimeric isoform of creating kinase CKMB can be produced. This invention further relates to a method of producing a recombinant human dimeric enzyme in an active form using a prokaryotic host, the recombinant enzyme products produced using the method of the present invention, and a transformed prokaryotic host constructed by the method of the present invention.

Title: Vibratory ground-survey system
Inventor: ANSTEY NIGEL A
IPC: G01V1/153
Filed: 1996-09-11
Abstract: A rotatory vibrating system is used in surveys of the acoustic properties of theshallow earth. The vibrator itself is of eccentric-mass (or "swinging-weight") form. Coupled to a flywheel, it decelerates freely from a selected high frequency to a selected low frequency. The observed deceleration rate is manipulated to give a measure of the said acoustic properties. The eccentricity of the vibrator is then annulled, and the flywheel and vibrator accelerated back to the selected high frequency for another measurement at another location. Display means are provided to facilitate visual interpretation of the results.

Filed: 1996-09-26
Abstract: A feed device for feeding rod-like articles,  such as filter tipped cigarette tubes,  from an axially moving feed supply to a conveyor moving normal to the axis of the articles, comprises a drum having a plurality of axially extending channel-shaped grooves around its periphery.   The rod-like articles are fed sequentially to the grooves and as the drum rotates, the articles are delivered in a single layer to the conveyor.  The drum can be wide enough to hold two articles in each groove and then alternate grooves have a stop positioned approximately half way.  With an article fed to each groove two rows of articles will be delivered to the conveyor.   Small holes can be formed in the bottom of the groove, to permit suction to be applied to the grooves.  Following placement of the conveyor, the tubes can be divided into lots of predetermined number, advanced to a holding position, and then filled into a box.

The alloy may be fabricated into sheet material suitable in a belt casting machine by casting the alloy while extracting heat from the alloy at a rate that avoids both shell distortion of the sheet and excessive surface segregation, at least until said alloy freezes. The alloy may then be subjected to a solution heat treatment, to re-dissolve precipitated particles and to a cooling process at a rate that produces a T4 temper and a potential T8X temper suitable for automotive panels. By such means, panels suitable for automotive use can be produced efficiently and economically.

Abstract: A portable hose cart apparatus for windably holding a flexible hose and for transporting thereof.  The cart includes a pair of vertical side frames shaped in the form of flanking arms each having a hub bearing surface.  The frame provides a base structure for steel components that are secured by use of rotatable frame fasteners.   The steel is encompassed by a seamless plastic sleeve that shrinks to the steel through a heating process.  Distal ends of the steel are bound by use of a wedge shaped locking block which frictionally secures the steel tubes to forward and upper support members.   A spool assembly is positioned between the frame sides forming a hose support surface therebetween, the frame sides having a shape to minimize plastic material yet maximize support when the cart is being transported.

Patent CA-2208966-A1 (CA)
Title: Yoke arrangement for an electric motor having an improved mechanical strength
Inventor: AOKI SUSUMU
IPC: B62D5/04
Filed: 1997-06-26
Abstract: In a yoke arrangement for electric motors which are particularly suitable for use in electric power steering devices, the yoke comprises a first tubular portion, a second tubular portion which has a smaller diameter than the first tubular portion, and a tapered section connecting the two tubular portions. The length of the tapered sections is desired to be minimized so that the overall length of the electric motor may be minimized. Reducing the length of the tapered section and thereby increasing the taper angle of the tapered section leads to the reduction in the mechanical strength of the yoke against an axial force. To compensate for this reduction in mechanical strength, the wall thickness of the tapered section is made larger than that of the first portion. Thus, the overall mechanical strength of the yoke can be ensured with a minimum increase in the material cost and manufacturing cost. The yoke may be formed by plastic deformation such as swaging and expansion.

Patent CA-2213765-A1 (CA)
Title: Submersible motor-driven pump with float switch
Inventor: GENZ OTTO
IPC: H01H35/18
Filed: 1997-08-20
Abstract: Liquid level-controlled submersible motor-driven pumps use so-called float switches which are capable of movement in the direction of buoyancy and enable or disable the power supply to the pump motor via a switching element, depending on their position. To this end,  it is customary to use float switches which are capable of moving roughly along a reference circle on the pump housing with the aid of flexible cables. In another configuration, floats are used which actuate a switch located in the pump housing. These pumps are consequently comparatively expensive and difficult to test, in that there may be an electrical or mechanical fault either in the pump circuitry or in the pump motor itself. In the case of the pumps with floats moving along a reference circle, free movement of the float can be obstructed by objects in the liquid or by the shaft wall, the result being that the pump is no longer switched on and off automatically. An electric submersible motor-driven pump (1) is therefore proposed, in which the float (8) and the switch (10) are accommodated in a separate component (6), which can be attached to the housing (2) of the submersible motor-driven pump (1) in detachable fashion and where the switch (10) interacts with a switchable adapter plug located outside the medium to be conveyed, between a power source and the pump motor (3). In this way, the pump can be converted to automatic control, in addition to which the function can be monitored more easily and free movement of the float is guaranteed.

Patent CA-2216177-A1 (CA)
Inventor: KRYCKI ROBERT D
IPC: B29C48/90
Filed: 1997-09-23
Abstract: A bubble guide unit according to the present invention comprises two concentric frames, at least one of which rotates relative to the other, through which the film bubble passes. At least four bubble guiding rods are arranged symmetrically to each pivotally engage one frame at one end and to freely engage the other frame near its other end. Freely engage here means that the other end of each rod is free to pivot to some extent as well as to move in the direction of its length beyond the pivoting point and back. This is most easily accomplished by a pivoting ring through which the rod passes or, less elegantly, by a fixed ring having an aperture larger than the rod diameter.

Abstract: The chewing tablets proposed contain a small amount of effervescent agent (which gives a pleasant fizzy feeling in the mouth), active substances and fillers in amounts chosen so that the tablets will nevertheless dissolve, with the exception of any insoluble or poorly soluble active substances, in 100 ml of water at 15 to 20°C in less that 120, preferably 90, seconds. This is achieved by virtue of the fact that the acid and/or carbonate particles in the effervescent agent are coated with a preferably readily, i.e. rapidly, soluble hydrocolloid and/or the active substance is free of encapsulation agents and the tablet mixture is free of lubricants. Tablet weight is 600 to 1500 mg, preferably only 700 to 1200 mg.
