Abstract: To reduce the need for manual work, improve productivity and reduce the fabrication cost in the method for molding a lead screw for converting a rotational movement into a linear movement, there are provided a method and a die assembly which may involve the steps of forming a plurality of holes in a wall of a tube in a spiral arrangement, preparing a metallic die assembly provided with a cavity defining a thread groove adapted to form the thread crest matching in position with an array of the holes, placing the tube in the cavity, and injecting synthetic resin material into the cavity so that the synthetic resin material may flow in two separate flows, one flowing inside the core tube, and the other flowing along the outer surface of the core tube. The thread crest is connected to the synthetic resin material filled in the core tube, and can be securely attached to the core tube. Optionally, an annular rotor may be fitted onto the base end portion of the lead screw. The synthetic resin material is first filled into the annular gap defined around the annular rotor before it is filled into the interior of the annular rotor so that the rotor may be prevented from being damaged by the tensile stress produced by internal pressure acting on the annular rotor.

Abstract: Shaped absorbent articles, such as catamenial pads and diapers, with a raised portion in the body facing side are disclosed.  The articles have one or more areas of adhesive, preferably in the form of longitudinal strips, disposed on the garment facing side for forming the raised portion.  By folding the garment facing side toward itself, the adhesive area adheres to either itself or to the garment facing side, thereby creating a raised portion that, in the example of a catamenial pad, would conform to certain portions of the perineal region of the user.  Methods of forming shaped absorbent articles are also disclosed.  In accordance with the present invention, portions of the garment facing side of an absorbent article are folded to adhere to portions of the garment facing side or areas of adhesive to create a raised portion in the body facing side.

Title: Method and apparatus for the diagnosis of visual stress and dyslexia
Inventor: MUMFORD ROBIN BRUCE
IPC: A61B3/028
Filed: 1995-05-25
Abstract: A quantitative visual test measures the rate at which an individual is able to complete a defined visual task, either on paper or on a self illuminated screen. The task involves comparing a plurality of similar appearing numbers to determine if they are an exact match within predetermined levels of time. Inability to complete the test within the predetermined level of time indicates the likelihood that the individual will exhibit visual stress and dyslexia. Individuals under such stress are then remediated by the use of adjusted lighting environments sometimes including other visual aids.

Title: Sensor positioning apparatus for trench excavator
Inventor: GEELHOED JACK
IPC: E02F9/20
Filed: 1994-11-07
Abstract: The present invention provides for excavating apparatus (10) which can comprise a vehicle (12) having excavating means in the form of a pivotal cutting boom (16) pivotably mounted by way of mounting means (20) on the vehicle (12). The cutting boom (16) has an endless cutting chain (24) drivingly mounted thereon and the boom (16) is pivoted relative to the vehicle (12) so as to vary the depth to which a trench (36) is current. In seeking to cut a trench (36) having a level floor irrespective of any undulations in the surface (14) upon which the vehicle (12) travels, a sensor (30) is associated with the apparatus (10) and is arranged to receive a reference signal (34).  Any variation in the location at which the reference signal (34) impinges on the sensor (30), for instance due to the passage of the vehicle (12) up an incline, serves to determine the angle at which the cutting boom (16) extends from the vehicle (12) and so vary the depth to which the trench (36) is cut.  In order to achieve an accurate relationship between the movement of the position at which the signal (34) impinges on the sensor (30), and the corresponding movement of the boom (16), the sensor (30) is mounted by way of mounting means (32, 38) in such a way that it can move relative to the cutting boom (16) along an arcuate path defined by arcuate guide means (40) having a centre of curvature that corresponds to the axis of rotation of an idler (22) about which the cutting chain (24) travels.

Abstract: Heavy metals are removed from waste lubricating oil by heating in the presence of an oxidation catalyst and a free radical initiator at temperatures in the range of about 150-200°C.  Corrosion and oxidation inhibitors previously added to the oil are thereby oxidized to form a separable sludge which contains the bulk of heavy metal contamination.  The process is of particular advantage in removing contaminating radioactive nuclides from lubricating oils used in nuclear generating facilities.
