Abstract: The invention is a road scarifier for cutting road surfaces, comprising: a frame provided with a cutter, supported by tracks by means of hydraulic actuators suitable for modifying the position of said cutter with respect to the road surface; driving means to obtain the setting in motion of the machine and the rotation of said cutter; right and left sensors arranged at the sides of the machine and suitable for measuring the distance from the road surface; sensors to show the inclination of said machine with respect to the horizontal plane.

Abstract: A valve (120) for controlling fluid flow therethrough in downhole applications is disclosed. The valve (120) comprises a valve housing having a valve closure mechanism (122) and a valve seat (124) disposed therein. The valve closure mechanism (122) has sealing surface (128) and a secondary load bearing surface (142). The valve seat (124) has a valve seat sealing surface (126) that mates with the sealing surface (128) of the valve closure mechanism (122). The secondary load bearing surface (142) of the valve closure mechanism (122) mates with a valve secondary load bearing surface (134) which may be supported by the valve seat (124).

Abstract: A beverage dispenser system includes a dispensing valve and an additive injector assembly linked with the dispensing valve. The additive injector assembly includes an injector unit for introducing additive flavoring to beverage fluid passing through the additive injector assembly from the dispensing valve. Moreover, a nozzle assembly linked with the additive injector assembly is provided by the beverage dispenser system for receiving beverage fluid and additive flavoring from the additive injector assembly. A base beverage with additive flavoring is thus dispensed from the beverage dispenser system via the nozzle assembly.

Abstract: A Magnetic, latent fingerprint development brush featuring a non-rigid, removable, disposable cover/body, to be used when developing latent fingerprints on contaminated surfaces. The cover can be removed and cleaned or disposed of and exchanged with a new cover. The non-rigid design allows operation without tension springs. The tip is less abrasive against surfaces being printed, since it has no sharp rigid edges. This lessens the chance of distortion of the latent print. The design is simple. A magnetic rod is attached to a handle, which is inserted into a flexible removable cover/body. A light grip holds the cover against the handle during use.

Abstract: A method for producing an organic cellulose derivative fibrillated fiber includes the steps of mixing a cellulose ester containing stream and a coagulant stream in a first zone of relatively moderate turbulence to produce a slurry containing cellulose ester fibers, passing the slurry containing cellulose ester fibers to a second zone having relatively low turbulence for a sufficient time to increase the hardness of the cellulose ester fiber; and passing the cellulose derivative fibers through a third zone having relatively high shear to produce a fibrillated fiber having a diameter of about 0.5 to about 50 microns and a degree of fibrillation greater than about 6.

Abstract: DNA encoding triol polyketide synthase (TPKS) has been isolated, purified and sequenced. Expression vectors comprising TPKS, cells transformed with the expression vectors, and processes employing the transformed cells are provided.

Abstract: An oil drain kit for collecting used motor oil comprising an oil drain collection pan, having a bottom wall raised at the center and sloping to its marginal extremity where it is joined with a side wall having a radial flange at the top of the wall and which extends circumferentially thereabout with a downwardly extending edge portion. The bottom wall is provided at its extremity adjacent its junction with the side wall with at least three discharge openings, each with a funnel spout extending downwardly therefrom. The spouts are adapted to receive the necks of empty oil containers which connect therewith and serve as supporting legs for the drain collection pan. A tray receives the containers when placed therein and facilitates sliding the kit under the oil drain plug of a motor to collect used oil draining therefrom and for removing it when draining is completed.

Abstract: DNA encoding triol polyketide synthase (TPKS) from Aspergillus terreus has been isolated, purified and sequenced. Expression vectors comprising said DNA, cells transformed with the expression vectors, and processes employing the transformed cells are provided.
