Title: Powered sweeper/chopper striker assembly for collecting and chopping materials like leaves from the ground
Inventor: JERTSON JOHN T
IPC: A01D51/00
Filed: 1992-05-21
Granted: 1994-04-05
Abstract: ABSTRACT A powered striker  assembly  for  collecting loose material on the ground has a shaft mounted for rotation about a horizontal axis at a predetermined distance above the ground.  The shaft carries an array of striker members. The striker members preferably comprise elastic nonrigid bodies.  In the absence of shaft rotation, the elastic nonrigid bodies of the striker members are normally flexed out of a perpen-dicular relationship with the ground.  In response to centrifugal force generated by rotation of the shaft, the flexed striker bodies mutually assume a perpendic-ular relationship with the ground for contacting and thrusting loose material.   In one arrangement, the striker bodies are bent upon themselves in a U-shape and inserted through holes in the shaft, where they remain without use of external fasteners or the like.

Title: Personal mobile communications system having central station for paging mobile users via base stations
Inventor: KAGE KOUZOU
IPC: H04W68/00
Filed: 1992-12-14
Granted: 1999-07-20
Abstract: A personal mobile communications system comprises base stations (4-1~4-4) located in respective zones and a paging station (8) covering an area including the zones, or cells (5-1~5-4). The paging station and all base stations are connected to a public switched telephone network (PSTN). When a call is originated from a PSTN user (2) to a mobile user (10), the paging station receives a call-setup request from the PSTN containing the address codes of both PSTN and mobile users, and broadcasts the call-setup signal over the covered cells. One or more base stations (4-1~4-3) receive the call-setup signal and, in response, broadcast an alert signal. One of the base stations (4-2) receives an off-hook signal from the alerted mobile station (10) and dials the PSTN user address code contained in the call-setup signal to the PSTN to establish a connection (15; 147~149; 176~178) between the calling and called parties (2, 10).

Abstract: An effervescent tablet is based on an effervescent system composed of carrier crystals of at least one solid, edible organic acid, of one or more components which form gas by reacting with the acid and producing salts, and of one or more salts produced from the acid and the gas-forming component. The carrier crystals are coated firstly with a layer of a different acid and secondly with a layer of a (preferably acid) salt derived from at least one of the two acids. Between ten and forty, and in particular between ten and twenty percent by weight of the total quantity of acids and gas-forming components used are in the form of the salts (preferably acidic salts). Carrier crystals consist in particular of nitric, malic, or tartaric acid, monosodium nitrate, and/or ascorbic acid. The first layer can contain d-gluconic acid-delta lactone and should be coated with nitric acid, malic acid and/or tartaric acid. This is covered with a layer of a monosalt formed by the reaction between part of the total quantity of gas-forming component and at least one of the acids used.

Title: Cardiac output probe assembly
Inventor: FONGER JAMES D
IPC: A61P37/06
Filed: 1992-08-20
Granted: 2004-06-22
Abstract: A cardiac output probe assembly (10) is disclosed wherein the assembly includes a chest tube (12) which carries a cardiac output probe (14) therein. The chest tube (12) includes a main lumen (40) for draining fluids from the thoracic cavity of the chest and a secondary lumen (18) which carries leads (24) attached to the probe (14). The probe (14) is attached to the pulmonary artery or aorta vessel with detachable tines (52) and/or sutures. The tines (52) are uniquely configured to ensure that good contact between the probe (14) and vessel is maintained. When cardiac output monitoring is complete, a pulling force is applied to the probe leads (24) extending out through a proximal end (18) of the tube (12).  The pulling force detaches the tines (52) and sutures, releasing the probe (14) from connection with the vessel. Further withdrawal of the leads (24) through the tube (12) retracts the probe (14) within the tube (12), where it is housed until the tube (12) is removed from the thoracic cavity.

Abstract: A method of and apparatus for precisely shaping heated glass sheets as the sheets advance along a bed of conveyor rolls. The conveyor rolls comprise a core member having axially aligned opposite sections and an arcuately curved central portion, with a flexible sleeve surrounding the core member. The sleeves are rotated in unison about the core members to convey the sheets. The core members are pivotable in unison between a first position where the curved control portions lie in a common plane for conveying the flat sheets and a second, lowered position whereat the curved portions define the shape to which the sheets are to be deformed. Vertically reciprocable top surface press units are mounted above the path of the glass sheets. The press units include curved stationary mandrels having freely rotatable flexible sleeves thereon.      The configurations of the mandrels are such that in operative position the mid portion of the mandrel of the first press unit is slightly close to the path defined by the conveyor rolls than the edge portions, and the edge portions of the second mandrel are slightly closer to the path than the mid portion.

Title: Complex combinatorial chemical libraries encoded with tags
Inventor: STILL W CLARK
IPC: G01N33/68
Filed: 1993-10-01
Granted: 2007-09-11
Abstract: Encoded combinatorial chemistry is provided, where sequential synthetic schemes are recorded using organic molecules, which define choice of reactant, and stage, as the same or different bit of information. Various products can be produced in the multi-stage synthesis, such as oligomers and synthetic non-repetitive organic molecules. Conveniently, nested families of com-pounds can be employed as identifiers, where number and/or position of a substituent define the choice. Alternatively, detectable functionalities may be employed, such as radioisotopes, fluorescers, halogens, and the like, where presence and ratios of two dif-ferent groups can be used to define stage or choice. Particularly, pluralities of identifiers may be used to provide a binary or high-er code, so as to define a plurality of choices with only a few detachable tags. The particles may be screened for a characteristic of interest, particularly binding affinity, where the products may be detached from the particle or retained on the particle. The reac-tion history of the particles which are positive for the characteristic can be determined by the release of the tags and analysis to define the reaction history of the particle.

Abstract: A centrifugal air blower has a housing with an inlet side wall through which a circular air inlet is formed. A cylindrical electric drive motor coaxially extends through the inlet opening and is drivingly coupled to a centrifugal impeller rotatably disposed within the housing. The motor is supported on the inlet side wall by a mounting system including a plurality of metal mounting rods each having an inner end, an outer end, and an elongated intermediate portion. The inner rod ends are welded to circumferentially spaced locations of a belly band structure coaxially clamped to the drive motor, and the outer rod ends are connected to resilient support assemblies arranged in a circumferentially spaced array on the outer side of the housing inlet side wall around the blower inlet opening. To provide the mounting system with a high degree of stiffness with respect to mounting system loads directed transversely to the motor drive axis, while at the same time providing the mounting system with a high degree of torsional flexibility, each of the intermediate rod portions is positioned to longitudinally extend adjacent and generally parallel to a line extending from the outer end portion of the rod to the center of gravity of the combined mass of the drive motor and impeller.
