Abstract: A method for encapsulation of antineoplastic agents in liposomes is provided, having preferably a high drug:lipid ratio. Liposomes may be made by a process that loads the drug by an active mechanism using a transmembrane ion gradient, preferably a transmembrane pH gradient. Using this technique, trapping efficiencies approach 100%, and liposomes may be loaded with drug immediately prior to use, eliminating stability problems related to drug retention in the liposomes. Drug:lipid ratios employed are about 3-80 fold higher than for traditional liposome preparations, and the release rate of the drug from the liposomes is reduced. An assay method to determine free antineoplastic agents in a liposome preparation is also disclosed.

Title: Method and device for adding and separating a low rate digital channel to the high rate channel of a transmission link
IPC: H04B17/00
Filed: 1989-04-27
Granted: 1993-02-24
Abstract: According to this method, on transmission, the signal S1(t) from a low-rate digital channel is added to that S2(t) from a high-rate digital channel by over-modulation or superposition means (13) which generate a composite transmission signal S(t). On reception, the signal S2(t) from the high-rate digital channel is recovered thanks to regeneration means (24) operating on the composite transmission signal S(t). The signal S1(t) from the low-rate digital transmission channel is recovered thanks to means (25) for subtracting the composite transmission signal S(t), previously filtered by a first low-pass filter (31), and the regenerated signal S2(t) from the high-rate digital channel, previously filtered by a second low-pass filter (33).

Title: Automatic coupling for railway vehicles
IPC: B61G1/40
Filed: 1989-05-10
Granted: 1992-02-12
Abstract: Each coupling head of a vehicle coupling comprises a spring accumulator 50 consisting of compression springs 27, 30 which are energized by a pressure bar 20 when a tension bolt 3 of the head is moved inward. The coupling of the tension bolt 3 in a tension bolt receptacle 4 occurs by engagement levers 12, which are locked by a displaceable frame 16 in the coupled state. The unlocking is remotely operable by actuation of a solenoid 45 which actuates a latch 32 through an unlocking bar 41. Because of this unlocking, the frame 16 is displaced by the force of the spring accumulator, so that the locking of the engagement levers 12 is released and the coupling can be decoupled.

Abstract: A device and method for permitting the separation of plasma or serum from whole blood. The device comprises a matrix of hydrophilic sintered porous material to which at least one red blood cell agglutinating agent has been applied. According to a first method of using the device, a sample of whole blood is applied to a first end of the matrix and the red blood cells within the sample come in contact with the agglutinating agents present in the matrix. The blood cells agglutinate, and are entrapped in the interstices of the matrix, while substantially blood-cell-free serum or plasma accumulates near the outlet of the device. A filter means in liquid receiving relationship with the matrix functions to wick the serum or plasma from the matrix. According to an alternative aspect of the invention, a filter means in liquid receiving relationship with the outlet of the matrix functions to retain any blood cells which pass through the matrix as the filter means wicks the plasma or serum from the matrix. Additional agglutinating agents may be incorporated within the filter means to facilitate retention of blood cells which pass through the matrix. Another aspect of the present invention involves a device for the measurement of a serum or plasma sample, utilizing a matrix of sintered porous material, such as sintered glass, sintered steel, sintered ceramics, sintered plastics, and eguivalents thereof. The matrix is characterized by a reproducible fluid uptake capacity proportional to the fixed dimensions of said matrix, a minimal reactivity with plasma or serum components, and a hydrophilic internal surface which enables the matrix to collect and retain a predetermined volume of sample for analysis. A further aspect of the present invention provides a porous reagent delivery system comprising a matrix of sintered porous material containing at least one reagent in a freeze-dried state, and method for making same. The system allows the delivery of a unitized form of a freeze-dried reagent which is recoverable upon contact with a liquid.

Abstract: What is proposed is a hinge joint for windows, doors and the like, in which a supporting or setting-out arm 3 is held pivotably via an angled intermediate piece 8 in a bearing block, seated on the frame or jamb, via an axle and engages on the intermediate piece 8 so as to be rotatable through 180 DEG  via a pivot axle 6-6 extending at right angles to this axle, but parallel to its longitudinal direction. The pivot axle 6-6 consists of a pin 16 which is fastened via a fastening base 15 so as to bear against a wide side of the supporting or setting-out arm 3 and so as to project beyond the rear end of the latter. So that the pivot axle between the supporting or setting-out arm 3 and the angled intermediate piece 8 not only can be produced easily and cost-effectively in large series, but furthermore also guarantees a simple and reliable connection to the supporting or setting-out arm 3, it is proposed that the fastening base 15 and pin 16 form a one-piece metal moulding 14, on which the fastening base 15 projects radially beyond the pin circumference essentially on one side only and forms at least one rivet shank (17a, 17b) which is limited in the direction of all three dimensions of space by polygonal surfaces, especially rectangular surfaces. <IMAGE>

Abstract: The present invention relates to an apparatus and method and uses a thin, yet strong plastic film (1) as the intermediate layer for the waterproofing material and the film has a plurality of perforations (2) therein. The film is highly resistant to crack propagation, and acts as a barrier to crack propagation between adjacent asphalt layers (5, 6), thus providing superior protection from the elements. The asphalt layers are interconnected with each other through the perforations in the polyester support layer. Because of the strength of the polyester film, only a very thin layer of polyester is necessary and this results in a substantial cost savings. As an alternative to coating, it is possible to extrude or laminate the asphalt onto the PET film. Also a layer of asphalt may be applied only to one side of said film and extruded through the perforations with heads on the columns (8) so formed to attach the asphalt to the film.
