Title: Multi-level folding stage
Inventor: LUEDKE THOMAS J
IPC: E04H3/12
Filed: 1992-08-07
Abstract: An elevationally adjustable folding stage (100) has a frame (102) which folds along a center of the stage (100) from a storage position to a use position. Stage panels (104, 106) of interchangeable widths form a stage surface and are reversible and interchangeable. The stage (100) may also support additional panels between stages (100) extending therefrom to form an extended stage surface. The stage (100) has a roller assembly (118) which lifts the stage (100) up so that rollers (120) engage the floor for rolling between storage and use locations. Connectors (135) between the frame (102) and the stage (104, 106) offer quick connection without additional pieces. Connectors (135) also provide for inserting risers to raise the height of one panel (104, 106) of the stage (100) relative to the other. In addition to the risers, multipanel supporting bases may be used to support the panels extending from the edges of the stage between stages. The panels between the stages may be stored on the stage (100) while in the use or folded position by hook members (172, 174) which rotate from a storage to a use position to retain the additional panels. Folding of the stage (100) is assisted by a spring folding assist member which prevents closing of the stage (100) and assists in the initial opening of the stage (100) toward the folded position. Accidental folding of the stage (100) is also prevented by a locking linkage (155) and a spacing linkage (192) which lock the stage (100) in the use position to prevent accidental folding and also to maintain the stage (100) in the use position when elevationally adjusting the stage panels (104, 106).

Title: Valve element
Inventor: ROGERS JOHN T
IPC: F04B53/10
Filed: 1994-02-25
Abstract: ABSTRACT OF THE DISCLOSURE A valve element is disclosed comprised of a body section, upper guide, lower guide, sealing section and reinforcement section. The reinforcement section is made of materials having a hardness greater than the lower guide and sealing section. The reinforcement section, as well as the sealing section, have a frustoconical outer surface to increase support of the sealing section due to bracing from a mating valve seat annular sealing surface. The frustoconical outer surfaces of the valve element combine to form a uniform frustoconical surface. Two sealing sections may be disposed above and below the reinforcement section. These two sealing sections have frustoconical outer surfaces that cooperate with the frustoconical surface of the reinforcement section to form a continuous, co-extensive frustoconical outer surface.

Title: Method for enclosing dental x-ray film pack and enclosure therefor
Inventor: TANAKA HIROYUKI
IPC: G03B42/04
Filed: 1994-04-05
Abstract: ABSTRACT    An enclosure useful in enclosing a dental X-ray film pack upon taking an X-ray picture of a tooth  is formed of an enclosing portion and a holding portion extending from the enclosing portion.  To permit en-closure of a dental X-ray film pack provided with a bite block, the enclosing portion is formed of two separate sheets.  After inserting the bite block into a basal part of the holding portion, the pack is covered between the two sheets and the two sheets are then fusion-bonded to seal the pack within the enclosing portion.  The holding portion has a length sufficient to extend out of an oral cavity when the enclosing por-tion is inserted in the oral cavity.  After taking the X-ray picture of the tooth, the dentist holds the en-closure at the holding portion, takes the enclosing portion out of the cavity, and then tears off the en-closure from a side of the holding portion, so that the dental X-ray film pack falls out of the enclosure.  The dentist is therefore free from the potential danger that the patient's saliva may stick to him.

Patent CA-2125963-A1 (CA)
Inventor: FARINA JAMES D
IPC: G02F1/035
Filed: 1992-12-04
Abstract: An optic intensity modulator includes a substrate (10) of an optic material that is conductive to light and acoustic waves and has both the electro-optic and piezoelectric properties. The optical modulator generally consists of a Mach-Zender interferometer comprising a pair of associated elongated light waveguides (11, 12) formed in the substrate, with the waveguides extending substantially coextensively with one another, and being separated from one another by a transverse distance that gradually varies along the courses of the waveguides. Different phase shifts are induced by imposing variable electric fields onto each of the waveguides by means of electrodes (21, 22, 23). Because of the varying spacing between the waveguides along their courses, the tendency of the acoustic waves that are generated during the operation of the modulator due to the piezoelectric effect to resonate between the waveguides at certain frequencies, is eliminated thus reducing the corresponding noise distortion.

Title: Pool cue support clamp
Inventor: COWAN DENNIS
IPC: A63D15/10
Filed: 1994-11-18
Abstract: A device for safely storing pool cues between plays to help prevent accidental dam-age to the cues and which is small enough to be carried easily and readily and quickly attaches to and detaches from any convenient edged surface such as a tabletop is com-prised of a generalized "C" clamp having a spring loaded clamping rod. The rod is pulled out of the clamp body by means of a rod handle against the action of a compression spring, compressing the spring and creating a gap between the end of the rod and one end of the clamp body. The clamp body is placed over an edged object such as a tabletop and the rod released. As the compression spring relaxes, the rod is forced against the underside of the tabletop, locking the clamp to the tabletop surface. A "V" block incorporated on the body of the clamp serves as a convenient resting place for the pool cue preventing accidental "knock overs". Where the edge of the tabletop is beveled significantly, an alternate em-bodiment comprises a stationery jaw upon which is spring mounted a movable jaw. The movable jaw is pried away from the stationery jaw against the spring action and the assem-bly placed over the beveled surface. The movable jaw is released and spring action clamps the assembly to the beveled surface. An integral "V" block located on the stationery jaw serves as a resting place for the cue.

Abstract: An AMPS system facilitates reception and processing of a DS CDMA signal transmitted by a mobile station (125). The AMPS system provides an alternate path for the signal to be received by a DS CDMA receiver (506) system. The DS CDMA receiver system generates a signal compatible with the AMPS system, adjusts the generated signal to be proportional to the DS CDMA signal and inputs the adjusted signal (510) into the AMPS system. The AMPS system then processes the adjusted signal for purposes of handoff of the mobile station (125) from the DS CDMA system to the AMPS system.

Title: Retroviral mediated transfer of the human multiple drug resistance gene
Inventor: BANK ARTHUR
IPC: A61K48/00
Filed: 1993-10-15
Abstract: This invention provides a mammalian retroviral producer cell constructed by transfecting a retroviral packaging cell with a retroviral vector containing the human multiple drug resistance gene. The mammalian retroviral producer cell produces retroviral particles suitable for tranducing target cells. Accordingly, the producer cell of this invention can be used to transduce target mammalian cell with the human MDR gene, and with a second, non-selectable gene, e.g. insulin, .beta.-globin or a major histocom-patibility gene. The producer cell of this invention can be used in methods of treating a mammal afflicted with a cancer and of treating a mammal afflicted with a disorder characterized by abnormal expression of a non-selectable gene which involve trans-ducing suitable cells from the mammal with the human MDR gene and then selecting with an MDR-responsive drug for cells which express the MDR gene. This producer line is demonstrated to be safe and free of replication-competent retrovirus in con-trast to the producer lines.
