Title: Belt conveyor and conveyor belt therefor
Inventor: TINGSKOG LENNART
IPC: B65G15/40
Filed: 1992-10-22
Abstract: A belt conveyor comprises an endless conveyor belt (4) of the type surrounding the material conveyed and having a central part (5) and two edge parts (6, 7) connected thereto. The edge parts are substantially flexurally rigid in the transverse direction of the belt. The belt conveyor further comprises a frame having support rollers for carrying the belt along at least part of its path.  The one edge part (6) of the belt (4) is divided into two portions closest to its free longitudinal edge so as to form a longitudinal pocket open towards the free longitudinal edge. The free edge portion of the other edge part (7) is received in the pocket so as to be substantially unable to rotate therein, and is forcedly retained owing to the connection of the edge parts to the central part. A rotary disc (15), tapering in the form of a wedge towards its periphery, is mounted in the frame so as to engage and widen the pocket to enable the introduction of the free edge portion of the other edge part (7) therein at a belt sealing location along the belt path.
Patent CA-2123119-A1 (CA)
Inventor: STOBBS THOMAS J
IPC: B60T15/02
Filed: 1992-12-01
Abstract: 2123119 9311370 PCTABS00022 A proportional pressure control valve (10) has a metering spool (42) which selectively meters flow between an axial first port (12) and radial second ports (14). The spool (42) is axially reciprocable with a larger face (40) toward the first port (12) and a smaller face (62) opposite from the first port (12), with a pressure equalization bore (60) through the spool (42). A first spring (64) extends between the smaller face (62) of the spool (42) and an armature (66) and the armature (66) is biased to a normal position by a second spring (74) and also has a pressure equalization bore (72) through it. Radial orifices (70) are formed in the end of the armature (66) facing the smaller face (62) of the spool (42), and the end of the armature (66) seats in the main bore (46) in which the spool (42) is seated. Passageways (90) extend from the orifices (70) to the second ports (14), and two selectively and variably energizable electromagnetic coils (80, 82) coaxially encircle the armature (66), one to draw the armature (66) to one side of the normal position and the other to draw the armature (66) to the opposite side. The normal position of the armature (66) preferably biases the spool (42) to an intermediate setting so that energizing the coil (82) which is toward the closed position of the spool (42) stiffens the response of the valve (10) and energizing the coil (80) which is away from the closed position of the spool (42) softens the response of the valve (10). Energizing one or the other coil (80, 82) also varies the exposed area of the orifices (70) to change the slope of the pressure-flow rate curve (98, 99, 100, 101, 102) at the particular energization level for low flow rates.

Title: Gas producing apparatus and method and apparatus for manufacturing optical waveguide and optical fiber preform
Inventor: SAITO MASAHIDE
IPC: G02B6/13
Filed: 1994-07-15
Abstract: There disclosed a gas producing apparatus for producing a glass formation gas required in an FHD method, a VAD method or an OVD method. A glass formation material is supplied intact in the form of a liquid to a vaporizer, and the supply quantity of this liquid material is controlled directly by a liquid flow rate control means while the material is kept in the form of a liquid. In addition, at the same time the liquid material is vaporized by the vaporizer, a fixed amount supply means supplies an inert gas or a combustion gas at a fixed flow rate to the vaporizer. Since this prevents a pressure rise in the vaporizer, the liquid material is stably supplied to the vaporizer. Therefore, a fixed amount of vaporization of the liquid material is constantly performed in the vaporizer without being influenced by variations in the atmospheric pressure.      Furthermore, since the vaporized material is supplied to a burner together with the inert gas or the combustion gas supplied at a fixed flow rate from the fixed amount supply means, the burner injects a fixed amount of the material gas at any instant.

Filed: 1994-08-22
Abstract: ABSTRACT OF THE DISCLOSURE      A hand-held compact diagnostic device is provided with a pair of instrument heads each requiring an inde-pendent source of illumination.  The instrument heads may be rotated into a fully extended position and once there-in, may be smoothly turned through 360 degrees in consecu-tive ninety degree intervals to accommodate any preferred orientation desired by the user.  Each instrument head is biased in the fully extended position and a rotated closed position.  Each instrument head is also adjustably biased to an aligned position for proper closure by the interac-tion of an adjustment collar with a pair of ball detents.          The adjustment collar further biases each head in three additional positions at ninety degree intervals for use when fully extended.  A pair of central terminals maintain continuous contact between each rotatable head of the device while a pair of radial terminals are in electrical contact only when the instrument head is  in a  fully extended position.  When the instrument head is rotated into the closed position, the radial terminals disengage to open the circuit between the source of illumination in the instrument head and a battery source contained within the device.

Abstract: A parts feeding apparatus includes a plurality of cassettes respectively holding therein rows of parts of different types and removably attached to a plurality of parts supply openings arranged at predetermined angular intervals along the peripheral edge of a rotating circular plate.  The circular plate is intermittently rotatable so that a selected one of the parts supply openings and the cassette attached thereto are positioned relative to the inlet opening of a parts delivery chute.  An open lower end of the cassette is opened and closed at predetermined time intervals by a reciprocating slide plate member disposed in a parts supply unit.  The parts feeding apparatus thus constructed is compact in size and simple in construction. Since the cassettes are arranged on the same circumference on the circular plate, the parts to be fed can be automatically and smoothly changed or switched from one type to another.  Thus, the apparatus is readily adaptable to the production of articles of different types to be manufactured in relatively small lots or in relatively large lots.
