Title: Lining a pipe
Inventor: MUCKLE DEREK
IPC: B29C63/34
Filed: 1997-07-10
Granted: 2001-11-20
Abstract: A method of lining an outer pipe (2) which may be of ferrous metal with a lining pipe (4b) of cross-linked polyethylene initially provided as a precursor lining pipe (4a). The precursor lining pipe (4a) is made by formin g an initial pipe of cross-linked polyethylene having an external diameter equ al to the internal diameter of the outer pipe (2), then the initial pipe is dra wn through a die to form the precursor lining pipe (4a) having an external diameter less than the internal diameter of the outer pipe (2). The polyethylene forming the precursor pipe (4a) is memory material having a material of the outer diameter of the initial pipe to which size outer diameter the precursor pipe (4a) expands automatically when the polyethylene  is melted. The precursor pipe (4a) is inserted in the outer pipe (2) and the  polyethylene is molten by drawing through the precursor lining pipe (4a) a burner (60) burning fuel gas supplied with combustion air through a hose (58 ) by which the burner is towed. The hot products of combustion melt the polyethylene causing the precursor lining pipe (4a) to expand automatically into the lining pipe (4b) which is supported, until the polyethylene solidifies on cooling, by gas pressure of a desired predetermined value insi de the lining pipe (4b). That gas pressure is derived from the pressure of the gaseous products of combustion which latter pressure may be augmented by the  pressure of additional air supplied to the interior of the precursor lining pipe (4a).

Abstract: The present invention relates to a system which makes use of a multiple reel  on which groups of flexible lines supported by articulated structures (8, 9)  are wound. The groups of flexible lines are interconnected at one end to flexible production and utility lines (4) emerging from the sea-bed and, at the other end, to connection blocks (10, 11) which may be connected to connection plates (15, 16, 17, 18) on at least one connection tower (13, 14)  fixed to the vessel. As the connections are redundant, it is always possible  to reposition one group of flexible lines while another group is connected, which gives the transfer system (2) total freedom of movement.

Abstract: A hydraulic raising apparatus with automatic regulated speeds can automatically adapt its raising speeds for various load conditions. It mainly comprises additional hydraulic circuits, check valves and adjustable relief valves arranged between the piston rod side chamber and the rodless side chamber of hydraulic cylinders and pumps. The arrangement enables hydraulic cylinders and pumps to change their working modes in a hydraulic circuit, depending on loaded conditions, from a piston type to a spool type and vice versa. Hence the hydraulic apparatus can adjust its raising speeds in agreement with loads. When the apparatus bears a light load, it will quickly carry the load to position. On the other hand, when the load is heavy the apparatus will move it at a slower speed and thus need just reduced input energy. Therefore, the apparatus according to the invention can enhance efficiency to the greatest extent.

Title: Patient support surfaces
Inventor: MAIER EDMUND K
IPC: A47C27/08
Filed: 1998-11-13
Granted: 2008-01-22
Abstract: Multiple varieties of patient support surfaces (10) are presented with a common modular assembly primarily including a perimeter chassis and integrated upper support element. Perimeter bolsters (14) provide relatively firmer support and facilitate safer transfers and better sitting at the edge of the bed. Pressure redistribution air cylinders (36, 38, 40, 42), turned either longitudinally or laterally, are captured by shaped, slotted inner bolsters (68, 70) and underside arches (88, 90, 92, 94) of an integral foam topper (24). Each foam topper (24) integrally incorporated may include a sloping heel pressure relief section for redistributing load to relatively more pressure-tolerant lower legs and calves. An external valving arrangement for a static non-powered embodiment permits practice of a "recharging" technique using an air pump (118) and self-calibrated valve (124), to return the air pressure in static air cylinders (36, 38, 40, 42) to their original manufactured specifications.

Granted: 2007-06-19
Abstract: The present invention is a qualifying connection (10) for an instrument (11) attached to a source of electrosurgery energy (12), and to the instrument that has first (15) and second (16) parts coupled to the instrument, and the source respectively. Optical couplings (17, 18) on the connection transmit invisible energy to identify the instrument, are proximate on the first, and second parts. A light modifier (24) on the first parts is proximal to the second part for modification of radiation in the infrared wavelengths so infrared transmitters encode signals, and non-contact coded proximity detectors (26) on the second part are the coupled detectors. Non-contact coded proximity detectors respond to modified infrared light establishing and nth bit identification code. An infrared light (19) supplied in the source passes from the transmitters accross the communicating couplings (17, 18) for encoding signals by modification of the infrared light with a light modifier. Mechanical attachments (20, 21) include conjugating male, andfemale portions physically extending between the parts for mating engagement.

Abstract: Method of, and apparatus for, inserting pouring spouts into a container are provided herein. The spout includes depending wings extending down from the bottom edge of the spout. The wings terminate in a point for piercing a container. The depending wings define an angle which is greater than ninety degrees with respect to the chute. Stop means are formed along the upper edges of the side walls of the spout, which permit the spout to open by pivoting about an arc of ninety degrees. The spout is inserted into a container with an apparatus which includes a ram which drives the spout against a ramp to rock the depending wings upward with respect to the bottom edge of the spout.  Thereafter, the ram drives the points into the container and the upper edges of the side walls contact the container and cam the back of the spout to a horizontal position. This allows the spout with the depending wings to be inserted into a container through slits that are sized properly to receive and hold the spout in the container.

Abstract: Methods for the identification of compounds which modulate, either inhibit or stimulate, biomolecules are provided. Nucleic acids, especially RNAs are preferred substrates for such modulation. The present methods are particularly powerful in that they provide novel combinations of techniques which give rise to compounds, usually "small"  organic compounds, which are highly potent modulators of RNA  and other biomolecular activity. In accordance with preferred aspects of the invention, very large numbers of compounds may be tested essentially simultaneously to determine whether they are likely to interact with a molecular interaction site and modulate the activity of the biomolecule. Pharmaceuticals, veterinary drugs, agricultural chemicals, industrial chemicals, research chemicals and many other beneficial compounds may be identified in accordance with embodiments of this invention.
