Title: High pressure discharge lamp having overcurrent fuse protection
Inventor: RAVI JAGANNATHAN
IPC: H01J61/54
Filed: 1993-10-22
Granted: 2003-04-22
Abstract: A high pressure discharge lamp includes a resistive fuse (30) for overcurrent protection of its associated ballast, which fuse is connected electrically in series with the discharge vessel (1) of the lamp and continuously dissipates power during lamp operation. The resistive fuse is heated by passage of the operating current through the discharge vessel (1) during lamp operation to a temperature substantially controlled by the operating current. In response to an increase in the operating current to a predetermined overcurrent, the resistive fuse reaches a temperature such that it breaks and disconnects the discharge vessel from its source of electric potential within a predetermined time period. The fuse passes short-term high starting currents anil does not disconnect the discharge vessel during each lamp start-up at least until the operating current reaches the predetermined over-current during lamp life.

Abstract: A gamma radiation dosimeter comprises a polyester film substrate 10, of which a central circular region 12 is coated with a gamma-radiation sensitive layer 14 which is covered by an overlayer 16. The radiation-sensitive layer 14 is formed from styrene-acrylonitrile copolymer and contains 1-bromoadamantane and a leuco dye. The overlayer 16 is formed from an acrylic resin binder containing a UV-absorber. The central region 12 is surround by an annular region 18 which is divided into six equally-sized sections 18a.....18f. Each section 18a.....18f is printed in a colour which corresponds to the colour developed in the central region 14 when it has been exposed to successive increasing amounts of gamma radiation.      After exposure of the device, the amount of radiation to which the device has been exposed can be determined by comparing the colour generated in the region 14 with the colours of the sections 18a.....18f. The colour of the section most closely corresponding to that of the central region indicates the dose of gamma radiation which the device, and any other object similarly exposed, has received.

Abstract: A ventilating element with a ventilator cap for mounting on the ridge, hip or arris area of a roof, and which has at least one elastically flexible sealing member that extends along a longitudinal edge area of the cap.  The sealing member is formed as a looped filament seal.  This configuration has the advantage that undesirable disorientations of the filaments are prevented.  This is because the loop structure has no free filament ends, and there is always a curvature in the end region which, on the one hand, prevents unintentional back-hooking, and on the other hand, imparts a certain coupling effect to adjacent loops, so that overall interlinking and interlacing of the individual loops are present, benefitting each other, especially by holding one another down, and preserving a close, flow-tight packing.  The loop filament seal is formed of filament material having an elasticity which ensures the sealing function is established by placing the individual filaments on top of one another, by overlapping them and so forth.

Abstract: An electromagnetic radiation source (S) such as an arc lamp, is located at a point displaced from the optical axis (o) of a concave toroidal reflecting surface. The concave primary reflector (M1) focuses the radiation from the source at an off-axis image point that is displaced from the optical axis. The use of a toroidal reflecting surface enhances the collection efficiency into a small target (T), such as an optical fiber, relative to a spherical reflecting surface by substantially reducing aberrations caused by the off-axis geometry. A second concave reflector (M2) is placed opposite to the first reflector to enhance the total flux collected by a small target.

Abstract: A control system for controlling the height of a harvesting head on a combine is disclosed herein.  The control system includes operator controlled signal generators which permit an operator to independently set the maximum velocity at which the harvesting head is raised and lowered.  The signal generators are connected to the system controller which controls the operation of a hydraulic valve which controls hydraulic lift cylinders which raise and lower the harvesting head.  The hydraulic valve is controlled with a pulse-width modulated signal. The width of the pulse is related to the direction the head is being moved (raised or lowered), and the maximum speed at which the head is to be moved.  To reduce jerking upon initiation of head movement and termination of head movement, the controller determines acceleration and deceleration rates for head movement initiation and termination.  The acceleration and deceleration determinations are based upon the signals produced by the signal generators.

Filed: 1993-03-02
Granted: 1999-01-26
Abstract: The invention relates to the automated planting of plantlets from a bare-root, cutting or tissue culture condition into a nursery container. The invention creates a continuous supply of v-notches (34) or open "sandwiches" or "books" of potting substrate, into which plantlets are placed, which then are closed around the plant roots or stem prior to automatic transplantation into a nursery container (46). The invention especially enables plantlets with small roots to be quickly and efficiently planted by an operator by "sandwiching" roots without injury or transplant shock. It is contemplated that this manual planting could be satisfactorily automated. The invention is useful for small plantlets or early stage germinants that have both root and shoot (such as tissue culture material derived from either micropropagation or somatic embryogenesis), but can also be used with rooted or unrooted cuttings, true or synthetic seed or naked embryos.

In the preferred embodi-ment of the present invention, text and im-age files for documents, such as for exam-ple patent documents, are initially stored on separate magnetic tape media. These data files are extracted from the respec-tive tapes and placed onto a faster medium, such as a hard disk drive. The text and image files are synchronized to produce Equivalent Files using heuristic algorithms to create an approximate equivalence re-lationship between the text and the image files. The Equivalent Files and image files residing on, for example, a hard disk drive or compact disk (CD), are coupled as a ne-source to a computer display system. The graphic user interface of the present inven-tion permits the user to display, manipu-late, and edit the Equivalent File created using the process of the present invention and to simultaneously view the image file on the display. Using the graphic user interface of the present invention, a user may create libraries of patent Equivalent Files and image files or documents of another type, as well as open cases to include a plurality of different patents or other documents. The Equivalent File may be selectively viewed on the display in an equivalent window. Simultaneous with the viewing of the Equivalent File within the equivalent window, the user may view any portion of an image file within one or more image windows on the display. A variety of other features and functions are provided by the present invention for the manipulation and display of patent documents and other documents on the user interface.
