Abstract: A rod guide fixedly molded around the shank of a sucker rod string with the rod guide including a radially inner non-erodible zone and a radially outer erodible zone. The non- erodible zone includes a radially inner substantially sleeve-shaped portion having an inner cylindrical surface for gripping engagement with the rod. A plurality of flow through channels are spaced outward of the substantially sleeve-shaped portion. Each flow through channel extends axially along the rod guide and has a maximum circumferential width greater than any gap in the radially outer surface of the erodible zone circumferentially aligned with and radially outward of the respective flow through channel. The radially outer surface of the erodible zone may have a cylindrical outer configuration, such that a radially outward substantially sleeve-shaped portion is provided for engagement with the tubing. The upper and lower surfaces of the rod guide may each be inclined such that the radially outer surface of the rod guide extends longitudinally in excess of the inner cylindrical surface of the sleeve- shaped portion and in engagement with the rod. A guided sucker rod includes an elongate rod having threaded end connectors for mating engagement with an adjoining sucker rod and one or more rod guides fixedly molded thereon. According to the method of the invention, left-side and right-side molds are created each including one or more elongate cavity creating member supported in a cantilevered fashion from a supporting end block. A plastic material is injected into the mold cavity, and the supporting end block is then moved longitudinally along the axis of the rod to remove the one or more channel performing members from the molded rod guide.

Title: A procedure and equipment for treating poultry before slaughter
Inventor: ANDREASEN BENT KLOSTER
IPC: A22B3/00
Filed: 1997-12-10
Granted: 2005-10-25
Abstract: The present invention concerns a procedure and equipment for the treatment, such as anaesthetisation or killing, of poultry by using gas. The gas comprises oxygen and carbon dioxide, among other components.  During the treatment, the oxygen concentration is kept constant at a normal level (18 - 22 vol.%). This is important as it allows the poultry to breathe normally while the natural body functions can be maintained in their normal state until anaesthetisation takes place. The concentration of carbon dioxide is increased either continuously or discontinuously. With the present invention it is possible to anaesthetise poultry before slaughter in a way which produces low levels of stress and discomfort in the poultry while, at the same time, the quality of the meat is better than with the use of traditional methods. In the equipment the poultry are exposed to the gas in a chamber (1), that may comprises a belt conveyer (5) and further be separated into three treatment zones (2, 3 and 4).

Abstract: A rigid and brittle bright metal flake is formed of a central layer of a reflective material supported on both sides by dielectric layers. In a preferred embodiment, the metal layer is aluminum having a thickness of about 100 nm and the dielectrics are either silicon dioxide or magnesium fluoride, each having a thickness of about 100 nm. The result is a very thin three-layered metal flake about 300 nm thick that exhibits a uniaxial compressive strenght of about 8 times a corresponding uniaxial tensile strength. As a result, the metal flake is then afforded the benefits of rigidity and brittle fracture during the manufacturing and applicational processes which ultimately provides favorable planar and specular reflectance characteristics in the visible wavelength range.

Abstract: A crankcase breather oil collector serves to capture oil vapor mixed with crankcase blowby gases, and contain the oil vapor to preclude its exiting to the atmosphere and/or collecting on external machinery components. The device basically comprises a canister which communicates with the crankcase of a four stroke reciprocating internal combustion engine by a tube or line. Blowby gases and oil vapor mixed therewith are routed to the canister by the tube or line, with the oil vapor cooling and falling out of suspension with the blowby gases to condense and collect as a liquid in the bottom of the canister. The blowby gases then exit the canister through a filtered vent or outlet. The outlet filter serves to preclude significant particulate matter from being expelled to the ambient atmosphere, and also serves to protect the engine by precluding the entrance of airborne contaminants to the engine when the engine is shut down and cools to provide a relatively low pressure within the crankcase. The oil collected within the canister may be drained by a petcock or drain valve for periodic proper disposal as required. While the present oil collector may be adapted to virtually any type of four stroke reciprocating internal combustion engine not having a positive crankcase ventilation system, it is particularly well suited for use with motorcycles, which are not required to have any form of emissions controls thereon.
