Title: Bending apparatus
Inventor: BRUGMAN JOHANNUS ANTONIUS HENR
IPC: B21D5/08
Filed: 1990-06-11
Abstract: An apparatus method for bending channel cross-section strip or panel material in which the material is passed between an infeed roller set 10, 16, 18, an intermediate roller set 12, 20, 22 and an outfeed roller set 14, 24, 26. At least one of the rollers of each roller set has two axially spaced annular projections which define an accommodation space for the flanges of the strip material. The axial spacing between these annular projections is reduced between the infeed and outfeed roller sets to enable the panel cross-section to be retained over a wide range of panel materials and curvatures.

Inventor: LILLARD DONALD W JR
IPC: A23L27/30
Filed: 1993-03-16
Abstract: During fructose crystallization by cooling a fructose solution, the rate of cooling is first reduced and then increased again.

Title: A repairable memory array
Inventor: WALLER DAVID L
IPC: G11C29/04
Filed: 1984-02-08
Granted: 1988-04-20
Abstract: The columns of a memory array are accessed by a plurality of column decoders, each decoder selectively accessing one column in a respective group of columns. Each column decoder can be connected to a respective data line by way of a first transistor, and the data line can also be connected to the decoder of a preceding group of columns by way of a second transistor. The second transistor associated with the first stage can connect the first data line to a spare column decoder accessing a spare group of columns. The conditon of each pair of first and second transistors is controlled by way of a respective normally closed fuse, and generally each column decoder is connected by its first transistor only to its respective data line. However, if defects are found in a group of columns, the associated fuse is blown to isolate that group from its data line. The second transistor is then rendered conductive to connect the data line to the preceding column decoder. Similarly, the data line of each preceding group is connected to the preceding column decoder with the first data line being connected to the spare column decoder.

Title: Improvements in and relating to a pull-bar type fastener assembly
Inventor: SUGDEN BRIAN
IPC: E05B13/10
Filed: 1988-06-30
Granted: 1990-11-14
Abstract: A pull-bar fastener assembly for sunken location in a door has a throw-bar (16) arranged for rotation about a central axis in unison with an operating handle. The throw-bar (16) has a bearing pin (19) at each extremity which faces but is spaced from the rear face (18) of a mounting plate to enable an end of a pull-bar (11a, 11b) to be slid between the bearing pin and rear face of the plate and then moved in the axial direction to locate on the bearing pin when the throw-bar is at a prescribed position relative to the pan. The rear face (18) of the mounting plate has a pair of retention ribs (21) which prevent the ends of the pull-bars moving axially out of engagement with the bearing pin (19) except when the throw-bar (16) is at a prescribed angular position relative to the mounting plate (13). <IMAGE>

Title: Closure locking mechanisms
Inventor: DOLMAN TERRY JAMES
IPC: E05B63/06
Filed: 1992-01-31
Granted: 1994-03-30
Abstract: A locking mechanism for a closure such as a window comprises a body (10) containing a gear wheel (26) that is rotated by a handle (36). This rotation is converted to a locking action by actuating members (23,24) which are provided with a helical thread (25) which engages helical teeth (26a) on the gear wheel (26). Rotation in one sense throws the members (23,24) out of the body to perform a locking action and reverse rotation retracts the members (23,24) into the body (10) in an unlocking action. The position of the members (23,24) can be altered simply by screwing the members into and out of the body. <IMAGE>

Filed: 1997-09-30
Granted: 2001-09-19
Abstract: The present invention relates to a cooling system for cryostats or transport containers for liquids incorporating a PTR cooler. The cryostat usually consists of several interior cylindrical or otherwise shaped vessels for storing liquids. In particular, the cryostat for NMR applications and related fields usually comprises an outer vacuum case, sometimes also a nitrogen can, as well as one or several radiation shields and the helium vessel housing the superconducting magnet whereas the latter usually is made of NbTi, Nb3Sn, and/or some HTC conductor. It is the aim of the present invention to use a pulse tube cooler by incorporation into an NMR cryostat via an opening, an opening refers to the neck tube itself or to any other means for accessing the cryostat for filling or for energising the magnet or acting conjointly as a pressure relief tube or/and as a drainage outlet e.g. for storage tanks and most generally for using the pulse tube as a means for rigidly suspending or supporting various parts in a cryostat. <IMAGE>

The or each cast section may be of channel section and narrower than the strip sections. The inclusion of a cast section or sections in the composite connecting rod enables the rod to be made more cheaply than a conventional one piece connecting rod made as a continuous stamped metal strip, and without loss of strength.

Title: Chain drive for construction toy system
Inventor: BOETTCHER RALPH J
IPC: F16G13/07
Filed: 1995-01-11
Abstract: A chain drive mechanism, especially for a construction toy system, is assembled with individual U-shaped chain link elements. The chain link elements are notched at their open ends and provided with bearing portions at their closed ends. The notched open ends are arranged for snap-fit attachment over the bearing portions of adjacent links, enabling a flexible chain of any length to be easily assembled. Drive pins, preferably coaxial with the bearing portions, project outwardly from each side of the chain links and are engagable with grooves of spaced-apart drive wheels, collectively forming a sprocket assembly. The drive wheels can be individual gear elements otherwise used in a toy construction system for gear drive mechanisms. The base portions of the U-shaped link elements are grooved transversely for the snap-fit attachment of construction toy connector parts, allowing the chain elements to carry other components.

Abstract: This Patent covers a method and the related equipment to measure exactly the flow rate in sewer systems. By using a basin (1) receiving the waste water from the sewer duct (2) and emptied at intervals by one or more pumps (3) it will be possible to measure the sewage flow (or volume) by establishing a maximum and a minimum level in the sewage basin (Q1 and Q2 respectively) while determining the time required to fill the tank between the two levels. Based upon the filling time, it will be possible to measure, with the aid of a computer, all data needed to determine the instantaneous, the average hourly and daily rates, minimum and maximum peak rates etc. Floats or sensors are (4, 5) positioned at these two levels (Q1, Q2) which will start or stop the drain pumps while transmitting the measuring time to the computer, i.e. the time required between stopping and restarting of the pumps.

Granted: 1979-05-10
Abstract: A liquid encapsulated high density integrated circuit package which serves as a complete computer basic system module having both logic and memory circuits in the same package. This unit takes advantage of improvements in the integrated circuit art to minimize the number of physical units required to provide the desired memory capacity while simultaneously maximizing density and thereby minimizing signal path length. Basically the package contains a plurality of stacked semiconductor wafers each of which provides either integrated memory or logic functions. Each semiconductor wafer is mounted on an insulated wafer carrier and is connected to stacking pins around the perimeter of the carrier via a series of radial interconnection which are flexible expansion leads disposed around the outer edge of the wafer. Each wafer is floatation mounted by attaching only its center to the carrier to minimize the stress effects of a thermal expansion mismatch between the wafer, the carrier, and the radial interconnections.
