Title: Method for varying the melting points and molecular weights of plyolefins using metallocene catalyst systems
Inventor: EWEN JOHN A
IPC: B01J31/00
Filed: 1987-09-25
Granted: 2002-03-05
Abstract: The present invention provides a method for varying the melting points and molecular weights of polyolefins by changing the structure of the catalyst used in the polymerization. The catalysts that are useful in the present invention are chiral, stereorigid metallocene catalyst of the formula R"(C5R' m)2MeQ. The catalysts include a bridge structure between the (C5R' m) groups and may contain substituents on the groups. It has been discovered that the melting points and molecular weights of the polymers produced by such catalysts are influenced by the bridge and substituents added to the (C5R' m) groups. Thus, the present invention provides a method for varying the melting points of the polymer product and a method of varying the molecular weights of the product by changing the components and structure of the metallocene catalysts. The present invention also provides a process for polymerizing olefins in which the melting points and/or molecular weights of the product may be controlled. Also included in the invention is the discovery that the melting points of the products are controlled by the number of inversions in the xylene insoluble fraction of the polymer.

Abstract: ABSTRACT    DEVICE FOR CONNECTING A HOSE END TO A           CONNECTING BRANCH     A connecting branch (1) has a nozzle (2) at one end and an annular collar (5) spaced therefrom, the nozzle being intended to be inserted into an end of a hose (3), in use, with a clamp (4), connecting the branch (1) and hose (3).  The clamp is formed of two partial shells (7a, 7b) connected together by a hinge pin (8), each partial shell having a retaining flange (10) engaging over the annular collar and a clamping flange (11) to press the hose (3) against the nozzle (2), in use The clamp is operable between open and closed positions by means of a tension lever (12) which is articulated to one partial shell (7b) whilst a spring (14) connects the lever (12) to the other partial shell (7a).  To prevent rotation of the clamp (4) in the circumferential direction about the nozzle, the annular collar (5) has two radial projections (6) which form a fork, accommodate between them the hinge pin (B) and pass through apertures (9) in the partial shells.  To prevent axial removal of the clamp from the nozzle the annular collar (5) has a radial extension (13), on its side diametrically opposed to the projections (6), of a length (L) greater than its unextended radius (H/2).

Title: Whistle
Inventor: FOXCROFT RONALD L
IPC: G10K5/00
Filed: 1988-06-13
Granted: 1990-11-27
Abstract: ABSTRACT          The invention provides a new whistle, intended for sports referees, and for small boat emergency use, where a loud piercing sound is required without the possibility of loss of sound by "over-blowing" or by sticking of the freely-moving ball used in conventional whistles.  The profile of the new whistle preferably is of flat-topped "mandolin" shape in side elevation, so that it is familiar and readily acceptable by established users, and yet includes three separate fipple-type whistle elements in a single whistle body, each with its own air column chamber and vibration-producing knife edge, at least two of which chambers are of slightly different lengths, so as to produce complex harmonics and beats that increase the piercing quality and audibility of the sound.  This is done by providing two elements side-by-side and parallel to one another, with the third also parallel and below (or above in an inverted shape) the other two protruding into the space between them.  The body is provided with a rearwardly-protruding boss into which the third column extends, so that its knife edge can be set back from the others to retain the desired side profile, and yet it can be the longest of the three.  The whistle is made as a three-part moulding, two of which fit within the third, the moulding parts providing different parts of the three element chambers, their knife edges, air-directing passages and the boss, so that all three parts can be moulded without the use of complex moulds and the whistle is complete when the three are assembled together.

Title: Apparatus and method for twisting pastry dough and the like
Inventor: UHROVIC MARTIN
IPC: A21C3/08
Filed: 1988-07-22
Granted: 1992-07-14
Abstract: Abstract of the Disclosure Apparatus for twisting dough comprises juxtaposed conveyor surfaces, each comprising a plurality of laterally spaced-apart conveyor belts moveable in parallel adjacency, each belt of each conveyor surface being juxtaposed with a belt of the other conveyor surface, thus forming a plurality of laterally spaced-apart belt pairs.  The juxtaposed conveyor surfaces thus form a conveying passageway.  A belt in a belt pair moves at a higher speed than the other belt in that pair, and the speed of the two belts is such that a substantially cylindrical object disposed across adjacent belt pairs is rolled between the adjacent belt pairs as it is being conveyed along the passageway.  The speed of the individual belts of the adjacent belt pairs is such that the net velocity along the passageway imparted to the object is the same at each of the belt pairs, but is also such that a greater rotational speed in imparted at one belt pair relative to that at the adjacent belt pair.  Therefore, as the object is moved through the passageway, it is twisted without being canted.

Title: Ferrofluid penetrant testing
Inventor: EVANS ROBERT S
IPC: G01N27/84
Filed: 1988-09-30
Granted: 1991-10-22
Abstract: ABSTRACT OF THE DISCLOSURE         A method for inspecting the surface of a workpiece for the presence of flaws using a ferrofluid as a penetrant which is applied to the surface of the workpiece and then scanning the surface of the workpiece with electrical detection means placed adjacent to the surface for providing responses indicative of the presence of flaws in the surface of the workpiece.  If desired, a magnetic field can be used to induce the flow of the ferrofluid into any flaws prior to inspection, and for post-inspection cleanup as well.  By the use of a,ferrofluid, the sensitivity of the electrical detection means, advantageously of the eddy current type, is enhanced in typical applications, and also allows the use of an eddy current probe to inspect workpieces made of nonconduc-tive and/or nonferromagnetic materials.

Title: Triazine-containing multisilane coupling agents for coating glass fibers, for adhesives, and for protective coatings
Inventor: MAGISTRO ANGELO J
IPC: C07F7/18
Filed: 1989-02-22
Granted: 1995-06-20
Abstract: At least three, and as many as eighteen, most prefer-ably at least nine, crosslinking sites are provided through the alkoxy groups in multiple chains on a triazine ring (hence "multisilane"), on a single molecule of  the multisilane. The multisilane, useful as a coupling agent, is formed by reacting a triazine-containing compound with a suitable aminoalkyl-alkoxoysilane, or, alkyl-aminoalkyl-alkoxysilane in either an anhydrous, or an aqueous liquid medium. A size containing the multisilane, enhances the reinforced properties of organic synthetic resinous mater-ials in which the fibers are used, and most particularly those of rigid poly(vinyl chloride) (PVC) with which it provides cohesive bonding of glass fiber surfaces. Glass fibers coated with a basic film former and the multisilane are covalently bonded on the one hand through some of at least nine alkoxy groups on each of the multisilane mole-cules, to Si atoms of a glass surface, and on the other hand, through at least some of the amine groups on each of the molecules, to the vinyl chloride (VC) resin in a reaction which involves allylic chloride bonds in the VC resin. The multisilane is effective in adhesives for a wide variety of materials, and in protective coatings.
