Title: Rotary drilling device
Inventor: REID NEIL GEORGE
IPC: E21B10/20
Filed: 1988-04-13
Abstract: The rotary rock drilling device comprises chiefly a body (1), a rotary cutting disc (2) and a counter-reaction member (3). The body (1), is fitted with means (101) for connection to a suitable rotary drive system, and it is traversed in the height direction by a conduit (102), (103) opening into orifices (104), (105), provided for the circulation of a drilling fluid. The cutting disc (2) is arranged on one side of the lower part of the body (1), the face of the disc (2) being orientated towards the concave bottom (501) and the cylindrical wall (502) of the hole (5). The counter-reaction member (3) is arranged on the side of the body (1) away from that carrying the cutting disc (2). The maximum radial projection from the axis of rotation (A) of the body (1) of any part of the counter-reaction member (3) is less than the radius of the hole (5). The surface of contact (301) between the counter-reaction member (3) and the hole (5) is situated below the line at which the concave bottom (501) of the hole (5) meets the cylindrical wall (502) of the hole (5). The lowest point (B) of the surface of contact (301), which closely matches the concave surface of the bottom (501) of the hole (4), is separated from the axis of rotation (A) by a distance (C) greater than the distance (D) from the lowest point (E) of the cutting disc (2) to the same axis (A).

Title: Antibody heteroconjugates for use in regulation of lymphocyte activity
Inventor: LEDBETTER JEFFREY A
IPC: C12N/
Filed: 1989-04-03
Abstract: The present invention relates to novel antibody heteroconjugates and their use in the enhancement or inhibition of T or B lymphocytes. The heteroconjugate are comprised of at least two molecules cross-linked to each other, each antibody being reactive with a different cell surface antigen on the same cell. The heteroconjugates appear to act by binding to lymphocytes via the interaction of the antibodies of the heteroconjugate with their respective cell surface antigens and bringing those antigens into physical proximity to each other, resulting in enhanced or reduced activation and function of the lymphocytes. The heteroconjugates, methods and compositions of this invention are therefore useful in the regulation of lymphocyte function, resulting in the improvement of cellular immune responses in various disease states.

Title: Device for producing carbonized water
Inventor: NOTAR ROBERT DIPL ING
IPC: B01F3/04
Filed: 1993-08-27
Abstract: A carbonator having a cooling system which is controlled by a controller responsive to input signals generated by an ambient temperature sensor, an ice thickness sensor and a water level sensor. After an initial ice build up following first turn-on of the system and depending on the ambient temperature sensed by the temperature sensor, the cooling system will turn on for a predetermined ON period followed by a predetermined OFF period. These ON and OFF periods are variable as a function of ambient temperature as sensed by the temperature sensor and will recycle in absence of any carbonated water removed. If, however, water removal takes place, the OFF period is interrupted and system turn-on will occur the next time a signal from the ice sensor is received and the ON and OFF cycle as determined by the system controller will resume unless it is again interrupted by another water removal signal from the water level sensor.

Title: Sprayable Portland cement-based fireproofing compositions
Inventor: PERITO RICHARD D
IPC: C09K21/02
Filed: 1995-04-24
Abstract: Sprayable fireproofing compositions for structural members such as steel columns are provided, as well as a method of applying multiple coatings thereof. The compositions comprise a Portland cement-based material, stucco, a high density aggregate and an accelerator. The compositions eliminate the long setting times typical of Portland cement-based materials, and improve the hangability thereof. The product is produced by dry blending a mixture of Portland cement, a high density aggreagte, stucco (calcium sulfate hemi-hydrate) and optionally, a stucco set retarder and shredded polystyrene aggregate. Upon the addition of water, sprayable slurries are formed which can be pumped to the point of application. An accelerator is added in close proximity to the point of injection. The slurries adhere to the structural member in the slurried state and after setting to provide excellent fire and heat protection. Because of the relative quick setting time of the slurry upon spray application, multiple coatings can be applied within the same working day.
