Title: Electrodeless high intensity discharge lamp having a phosphorus fill
Inventor: LAPATOVICH WALTER P
IPC: H01J61/12
Filed: 1997-01-30
Abstract: An electrodeless high intensity discharge lamp including a sealed light-transmissive envelope, a volatilizable chemical fill and an inert gas or nitrogen within the envelope. The chemical fill includes as a primary active component phosphorus or a volatilizable compound of phosphorus.      The inert gas or nitrogen is at a pressure of less than 760 torr at ambient temperature, and assists in starting the lamp. Sufficient mercury may be added to the lamp fill to improve resistive heating, but addition of mercury is not required for emission. Sulfur, a sulfur compound, or a metal halide may be added to the fill as a secondary active component. The lamp envelope is coupled to a high frequency power source to produce a light emitting plasma discharge within the envelope.

Title: Tandem bicycle propulsion system utilizing a shared footpedal and crank assembly
Inventor: KIELLAND PETER JOHANN
IPC: B62K3/12
Filed: 1997-03-14
Abstract: A kit of detachable parts which modify a single rider bicycle such that it accommodates two riders. Each rider applies propulsive force to a common crank-arm and chainwheel assembly by means of two shared footpedal assemblies which transmit both riders' foot pressure onto the same pedal bearing spindles. Each of said footpedal assemblies is comprised of upper and lower footpedal members upon which the front and rear riders respectively apply propulsive foot pressure. The upper (non-rotateable) footpedal member is affixed to the lower (rotateable) footpedal member and extends outwards from the bicycle, thereby permitting either heel or toe pressure to be applied by the front rider. The upper pedal is suspended above the lower pedal by means of compression members disposed such that the rear tandem rider can insert the forepart of each foot between the pedal members to exert foot pressure onto the lower, rotateable footpedal member. Said lower member has a rearward extension used by the rear rider to stabilize the pedal assembly against torque induced by the front rider's eccentric point of pressure application. The rear tandem rider's seat is adjustably affixed onto a support rail assembly at a location behind and substantially lower than the front rider's seat. An adjustable support mechanism permits the front rider's seat to be both raised and advanced with respect to its single rider location such that the legs of the closely coupled riders do not interfere with each other during pedaling activity.

Title: Aglucone isoflavone enriched vegetable protein extract and protein material, and high genistein and daidzein content materials and process for producing the same
Inventor: ALLRED MARYANN C
IPC: A23L11/30
Filed: 1997-09-03
Abstract: An aglucone isoflavone enriched vegetable protein extract and protein material are provided, as well as a high genistein content material and a high daidzein content material. Isoflavone conjugates in a vegetable material are converted to isoflavone glucosides by treating the vegetable material at a temperature and a pH for a period of time sufficient to effect the conversion. The isoflavone glycosides are converted to glucose isoflavones by enzymatic reaction. The vegetable material is extracted with an aqueous extractant having a pH above about the isoelectric point of protein in the vegetable material to extract protein and the isoflavones either before or after conversion of the isoflavone conjugates to isoflavone glucosides or the conversion of the isoflavone glucosides to aglucone isoflavones. An aglucone isoflavone enriched protein material is produced by precipitating the protein and aglucone isoflavones from the extract. A high genistein content material or a high daidzein content material may be produced from the aglucone isoflavone enriched protein extract or aglucone isoflavone enriched protein material by separating the high genistein or high daidzein content material from the extract or protein material.

Title: Riser clamp and method of fabricating same
Inventor: COSENTINO CHRISTOPHER
IPC: F16L3/10
Filed: 1997-11-25
Abstract: A low-weight riser clamp has a pair of clamp members stamped from metal strips. Each metal strip is bent lengthwise to define an elongate base strip and a pair of opposing lengthwise flanges. The base strip is bent to define between the flanges a substantially semi-circular central arch, a pair of coplanar arms that extend laterally in opposite directions from the central arch, and a pair of tabs each extending laterally away from the arms. The arch and the flanges extend in the same general direction from the metal strip, and each tab is offset from its associated arm in an opposite general direction. Clearance holes are formed in the arms to pass bolts. When installed about a riser, the tabs of the clamp members abut one another to space the arms of the clamp horizontally. Thus, as the bolts are tightened, the butted tabs serving as fulcrums about which the arms deflect, permitting more reliable gripping of the riser. The configuration of the clamp permits a significant reduction of material costs without a significant increase in manufacturing costs.

Inventor: MCCOY BRIAN T
IPC: H01H77/10
Filed: 1997-12-17
Abstract: A circuit breaker mechanism has a contact arm (56) forming a portion of an interruptable load current path through the circuit breaker and mounted with respect to a pivot (110) for swinging motion to break the current path.  A spring-loaded, over-center operating mechanism includes a toggle mechanism having an upper toggle (74) and a lower toggle (122) coupled by a spring pin (128) to form a toggle joint about which the toggles can relatively pivot.  The spring pin has a circular groove (128b) at which it operatively connects to the toggle joint, and a circular surface (128a) adjacent the groove is disposed in the path of travel of the contact arm as the contact arm swings to break the current path.  A V-shaped notch (56a, 56b) in the contact arm, acts between the toggle joint and the contact arm to locate the toggle joint radially of the contact arm pivot and thereby cause the toggle joint to be displaced by the swinging contact arm along an arc such that a principal component of the contact arm force is directed in a sense that fully, or at least approximately, maximizes the effect of the swinging contact arm force on the toggle mechanism.

Title: Self-locking lock
Inventor: GONSER GERHARD
IPC: E05B15/10
Filed: 1998-01-20
Abstract: The invention relates to a self-locking lock with a bolt, a lock swing catch andan auxiliary swing catch, in which the bolt and lock swing catch move outwardly to a locking position in spring-loaded manner and with the door closed, and are there lockable by a slide plate whilst the auxiliary swing catch presses on a locking plate. With the door open, the bolt is held back in a housing of the lock and is arrested by the auxiliary swing catch by means of the slide plate. In order to provide a lock secure against manipulation and reliable in operation, where an uncontrollable extension of the bolt is particularly effective prevented even in intermediate states of the opening and closing process, on opening the bolt leads compared with the lock swing catch and is arrested completely retracted in the housing of the lockwhile the lock swing catch is provided with a widening, for instance, a pivotable, spring-loaded swing catch part. As a result, the lock swing catch engages for a longer time on the locking plate and lags behind the auxiliary swing catch, so that the slide plate and bolt are arrested until the auxiliary swing catch arrests the slide plate and bolt. The lock swing catch widening has no effect on closing.
