Title: Latch engaged removable mullion assembly
Inventor: HIGGINS ANTHONY L
IPC: E06B1/52
Filed: 1995-03-22
Abstract: A mullion assembly mountable in a door frame includes a bottom fitting attached to a floor and a top fitting attached to the door frame above the bottom fitting.  The top fitting supports a latch engagement assembly for engaging a latch assembly positioned in a mullion cavity of a mullion.  The latch assembly has a latch extendable from the mullion cavity to engage the latch engagement assembly supported by the top fitting and hold the mullion in a fixed position.  Retraction of the latch is controlled by a key lock assembly connected to the latch assembly through an actuating link assembly.          The key lock assembly permits key controlled disengagement of the latch from the latch engagement assembly, followed by temporary removal of the mullion from its position in the door frame.

Abstract: A method of assaying for glycosyltransferase activity in a sample. In a first step, a sample is reacted with a first sugar don-or and an acceptor substrate to produce a transferase product. The first sugar donor and acceptor substrate are selected such that the sugar from the first sugar donor is capable of being transferred to the acceptor substrate in the presence of the glycosyl trans ferase to be assayed. In a second step, the transferase product is reacted with a second sugar don? having a sugar which is la-belled with a labelling agent and an enzyme which is capable of transferring the sugar from the second sugar donor to the trans-ferase product to produce a labelled transferase product and which has a higher affinity for the glcosysyltransferase product compared to the affinity of the glycosyltransferase for the acceptor substrate. The labelling agent activity of the labelled transfer ase product or unreacted second sugar donor is assayed to determine transferase activity in the sample. A kit for assaying for gly-cosyltransferase activity in a sample is also described.

Title: An emergency power system
Inventor: THOMSEN OVE LYCK
IPC: H02J7/34
Filed: 1994-02-11
Abstract: An emergency power system is connected between an AC voltage source (10) on the input and a load (Z) on the output. The emergency power system ensures a stable voltage on the output, even if the AC  voltage received from the AC voltage source (10) is irregular or is interrupted briefly. The emergency power system comprises an AC/DC converter (14) coupled between its output terminals and an AC regulator (20) positioned between the input and the output. The AC/DC converter (14) is coupled to a chargeable battery (12) and serves as a charging rectifier for the battery (12) in normal operation and as an inverter in emergency operation, the battery voltage being converted to AC voltage on the output of the emergency power system.  This can be done without changing the control of the converter (14) and the regulator (20). The AC regulator (20) is built as a controllable current generator supplying on its output an AC current which is in phase with the AC voltage received from die AC voltage source (10). Irrespective of the energy direction through it, the AC/DC converter (14) maintains the predetermined AC voltage (V out) across the output terminals of the emergency power system. The system moreover includes a comparison means (28) which senses and compares the battery state to a predetermined reference and supplies a signal in response to this. The intensity of the current supplied by the regulator (20) is controlled in response to the signal generated by the comparison means (28), so that in terms of energy the system is in power balance.

Filed: 1994-02-25
Abstract: A trocar (10) for placement in the lumen (24) of a cannula to facilitate insertion of the cannula (20) through the wall of a body cavity is described. The trocar (10) comprises a handle (28), an obturator (30) having a proximal portion (31) and a distal portion with a cutting surface (35) for piercing the wall of the body cavity, and an axis (A). The proximal and distal portions of the obturator (30) are mounted for relative rotational movement about the axis (A) of the obturator (30). A  mechanism retracts the obturator (30) proximally relative to the cannula (20) along an axial path as the proximal (31) and distal portions rotate relative to each other after the cutting surface (35) has at least partially penetrated through the wall of the body cavity. Preferably, the path is free of distal movement of the obturator (30) relative to the cannula (20).

IPC: F24C3/14
Filed: 1995-11-07
Abstract: An all-metal, hand-portable, light-weight heating device serves as a self-contained oven, as a stove, or as a space heater. The box-like device comprises hollow sheet-metal back, side and tap walls and door. An enclosed heater chamber beneath the oven enclosure includes a removable, slide-in top closure plate, which channels hot air to the interior of the hollow walls when used as an oven or space heater; removal of the closure plate enables use of the device as a stove. The preferred material is sheet aluminum. A portable gas bottle can be used as the fuel supply. Excess secondary air is available, induced by the operation of the gas burner. This induced flow of cool air creates a high thermal gradient between the inner and the outer heated wall surfaces, so that the outer surfaces of the device operate at a safe, non-searing temperature. The device can be used for camping, cook-outs, or for emergency situations, or for household use as a regular oven or stove in third world communities.
Patent CA-2162621-A1 (CA)
Inventor: TESSMANN UWE
IPC: B24B7/12
Filed: 1995-11-10
Abstract: In order to produce drive belts with small rotation-angle error, the rotation-angle error of a specific drive belt (6) is measured. Instead of the selection of low-error drive belts, the invention provides that, after the measurement has been performed, the drive belt is physically altered in a part of its length, in such a manner that the rotation-angle error is rendered more or less equal to zero. According to the invention, this physical alteration of the drive belt (6) is realized by the removal of material - effected, for example, by a grinding operation - from the contact surface (7) of the drive belt (6) according to the measured rotation-angle error. For every type of belt, there exists a clear relationship between the rotation-angle error and the amount of grinding required for the correction thereof, it being possible empirically to determine said relationship.
Patent CA-2163328-A1 (CA)
Inventor: FLANAGAN HUGH L
IPC: H01M2/38
Filed: 1995-11-20
Abstract: A charge-retention battery includes in a cover a plurality of reservoirs corresponding to the cells of the battery.  The cover has the lateral dimensions of a conventional battery case and shortened sides.  Minimum length transfer tubes run between the reservoirs and the cells, through the lid of the battery. The tubes fit between adjacent battery plates, with only slight modification of the plates required.  To remove electrolyte from the cells and prevent self-discharge, inert gas under pressure is fed to the cells.  The gas forces the electrolyte from the cells, through the transfer tubes and into the reservoirs. To place battery in service, the gas is released and electrolyte flows from each of the reservoirs, through the transfer tubes to the associated cells.

Abstract: These invention relates to metal-complexing, cystein-free peptides which may be coupled to an organ-specific probe directly or via a linker and are thus enriched as conjugates specifically in tumours, organs, tissues or centres of inflammation. The organ-specific probes used are, for example, antibodies or part-sequences of antibodies against tumour-associated antigens, e.g. the carcino-embryonal antigen (CEA, which are thus specifically enriched in tumours. The invention also relates to processes for producing the metal-complexing cystein-free peptides and their conjugates. The present invention also relates to the use of the conjugates as components of a kit for in vivo diagnosis or in vivo therapy and radio-pharmaceuticals containing these conjugates together with radio-isotopes. The organ-specific conjugates are used to image tumours, organs or centres of inflammation.
