Patent EP-0083205-A2 (EP)
Title: Apparatus for producing castings in a vacuum.
Inventor: GODDARD JOHN
IPC: C30B11/00
Filed: 1982-12-22
Abstract: Apparatus for casting in a vacuum has a single evacuable furnace chamber 10 in which the charge melting and mould heating takes place. The charge is melted in a crucible 24 by an induction coil 20, while the mould is heated by resistance heaters 18 which are made from a FECRALLOY (Registered Trade Mark) material and can be operated in air or vacuum. 
     In operation an empty mould 16 and a charged crucible 24 are positioned in the furnace 14 and the furnace chamber is sealed. The heaters 20 and 18 are operated while the furnace is pumped down. A control device 40 ensures that the charge is not melted until the appropriate vacuum level has been reached. After pouring the filled mould is withdrawn into a withdrawal zone 25 and as soon as the casting has solidified to the extent that air can be admitted to the chamber without detriment, the vacuum is released and the mould and charge replaced. 
     The furnace described is relatively inexpensive, having no water cooled valves between chambers, and the process is relatively quick and inexpensive due to the heating of the mould during evacuation of the chamber.

Abstract: The invention relates to a rotary switch, especially a rotary load-break switch, which has movable contact structures rotatable into and from bridging engagement with stationary contacts. 
     Each movable contact structure (85 or 127) comprises two substantially parallel bridging contacts (87, 89 or 137, 139) each of which is straddled by a magnetizable channel member (95, 97 or 133, 135) having flanges which, together with the flanges of the magnetizable channel member on the other bridging contact, define air gaps enabling the channel members to be magnetically mutually attracted and thereby apply contact-pressure producing forces to the bridging contacts upon flow of a predetermined current therethrough. 
     The movable contact structures are positioned in openings (53-59 or 129-131) formed in a unitary shaft (7 or 119) common to all poles of the switch, and, when open, are maintained in positive alignment by reengagement with the associated stationary contacts by contact aligning portions (61 or 123) formed integral with the shaft (Figures 1-5) or with the switch housing (Figures 6-11) supporting also the stationary contacts.

Abstract: The device for ball games and the like, in particular for tennis, comprises several signal transmitters (I to VII), each of which responds to a component of force, which is characteristic of the racket grip or of the sequence of movement of the racket during a stroke, by emitting a signal. The signals emitted by the signal transmitters (I to VII) are analysed in a processing circuit and processed to form an overall indication which informs the player either acoustically or visually whether the handling of the racket was correct or incorrect during the execution of a stroke cycle. <IMAGE>

Abstract: There is disclosed an ultrasonic scanning apparatus for directing ultrasonic energy towards a body under investigation, such as the body of a person. The scanning apparatus consists of a focussed ultrasonic transducer which is capable of radiating a beam of ultrasonic energy in a given direction. The beam emanating from the transducer impinges upon at least one surface of a rotating reflector where the rotating reflector directs the beam relatively perpendicular to the direction of the beam as propagated from the transducer. The redirected beam can then be further focussed or reflected to further shape the beam prior to directing the beam towards the body under investigation.

IPC: B29C48/793
Filed: 1984-07-05
Abstract: This invention relates to a method and apparatus for removing hot volatiles and moisture from particulate plastic material being fed for injection or extrusion molding by a plasticizing screw which rotates in a heated barrel. Flow control means, such as a conveying screw or rotary valve, drop the particulate material downward through a vertical feed passage extending to an opening in the barrel. At the same time, suction is applied to remove hot volatiles which are released through the opening in the barrel as the particulate plastic material is gradually melted as it is compressed by the screw. The rate of feed of the particulate material is restricted so that the barrel of the plasticizing screw is only partially filled near the opening, thereby improving the withdrawal of the gases from the barrel. The incoming particulate material is preheated by a continuous flow of hot air through it as it passes through a tubular guide member. The air flowing to the preheater passes through a heat exchanger where it recovers some waste heat from the hot gases withdrawn from the barrel to improve efficiency and reduce power costs.

Abstract: A Fresnel phase plate lens of either the phase reversal plate or sinusoidal phase reversal plate type is formed by photolithography in materials hitherto not available to be used to Fresnel phase plate lenses. The material for the desired Fresnel phase plate lens may be chosen for its optimum spectral transmission range. For example, for infrared spectral transmission, silicon and germanium are chosen for the materials to have the Fresnel phase plate lens formed therein. For the visible spectral transmission range various glasses such as crowns, flints, and borosilicates glasses of suitable optical quality are useful. High silica glasses and fused quartz (silicon dioxide) are useful as the lens material for ultraviolet spectral range.

Abstract: The present invention teaches a method of producing butt welds between pipes or ducts of fluoropolymers, which are extremely chemically inert and which have continuous service temperatures in the range of 300 to 500°F (149 to 260°C) or more, by simultaneously applying infrared or radiant heat to the ends of the pipes or fittings to be welded but without touching the ends being radiated. The radiant heat is derived from a flat faced electric quartz infrared heater which has a surface temperature in excess of 1600°F (871°C) and which is maintained for fifteen to forty-five seconds at a spacing of approximately one-fourth to one-half of an inch (6.35 to 12.7 mm) from the end face of the duct. The time varies with the size of the pipe being welded; and the heater to pipe spacing may vary widely, from 0.125 inch (3.175 mm) to as much as 2.0 inches (50.8 mm).
