Abstract: Preparation of active therapeutic proteins comprising two essential steps. In the first step an active protein source is treated under conditions sufficient to inactivate any viruses present (e.g. via heat or chemical treatment).      In the second step, the treated active protein source of moderate purity is then treated under conditions sufficient to remove impurities as well as denatured (once active) proteins resulting from the viral inactivation step. In an illustrative embodiment, a biologically active protein such as antithrombin is treated under conditions sufficient to assure viral inactivation and minimal antithrombin deactivation. After the viral inactivation, the antithrombin is contacted with immobilized heparin to complex only the active antithrombin which is then eluted by known means and processed further (e.g., to include desired excipients and then freeze dried). The preferred resulting concentrate is characterized by a high degree of purity, virus inactivation, and absence of denatured or inactive protein (generally less than about 10% by weight inactive form or, in the case of antithrombin, less than about 10% as determined, for example, by crossed immunoelectrophoresis).

Title: Error-correcting bit-serial decoder
Inventor: SHIMADA MICHIO
IPC: H03M13/33
Filed: 1987-09-21
Granted: 1991-08-06
Abstract: ABSTRACT OF THE DISCLOSURE:     In an encoder replica of a decoder for an input code sequence which corresponds to a code symbol sequence comprising an information symbol sequence and a redundancy bit sequence, a one-bit memory (46) successively memorizes consecutive bits of the input code sequence as memorized bits.  An output circuit (62) delivers replica output bits in bit series to a sequential decode controller (43) in response to the memorized bits.  In response to the memorized bits and a control signal produced by the controller in response to the input code sequence and the replica output bits, the encoder replica decodes the input code sequence into a reproduction of the information symbol sequence.          Preferably, the output circuit is controlled by a position counter (64) giving separate indication of bits corresponding in the input code sequence to the information symbol sequence and of bits corresponding in the input code sequence to the redundancy bit sequence.  More preferably, a synchronism shift counter corrects the separate indication in consideration of a shift in synchronism of the separate indication relative to the input code sequence.

Title: Round bale loader and carrier
Inventor: ELIAS JOHN
IPC: A01D90/08
Filed: 1987-10-22
Granted: 1992-01-07
Abstract: ROUND BALE LOADER AND CARRIER     ABSTRACT OF THE DISCLOSURE         Conventional bale carriers and/or accumulators include mechanisms which receive the bale from the ground and to one side of the carrier and then lift it onto the carrier rails.  Either forks or impaling spikes are used to engage the bale.  When it is desired to receive the bales directly from the round baling machine, difficul-ties are encountered because the bale is ejected trans-versely relative to the carrier or accumulator frame so that it is not possible, with conventional structures, to pull the carrier or accumulator behind the baler.   The present invention includes means to receive a bale trans-versely over  the  front  of  the carrier or  accumulator which may be pulled immediately behind the baler,  and then swing the bale through 90° so that it lies longitud-inally relative to the carrier or accumulator.  The bale is then engaged upon the ground so that when the carrier or accumulator  is moved forwardly with the baler,  the pickup rails engage under the rounded sides of the bale and elevate it as the carrier or accumulator is raised to the transport position, with the bale ready to be moved rearwardly along the rails by the next succeeding bale ejected from the baler machine.

Abstract: A sample rate converter receives an input stream of samples representative of a time-varying signal and generates a corresponding output stream of samples which is also representative of the time-varying signal and in which each output stream sample appears at a desired time which may differ from the time when a sample appears in the input stream; filter circuitry receives the input stream and generates at least two intermediate samples which appear at different times, and interpolation circuitry combines selected intermediate samples to form a sample of the output stream at the desired time.  In another aspect, an improvement is provided for a modem of the kind in which a line signal is sampled at times governed by an unstable clock to generate a first sample stream in which the samples appear with possibly changing sampling phases and a converter converts the first sample stream to a second stream of samples appearing at times that are possibly different from the times of appearance of the samples in the first sample stream; the improvement is means for providing to the converter signals representative of the changing phases of the samples in the first sample stream to cause the conversion to occur in a manner that reduces the contribution of the changing sampling phases to the times of appearance of the samples in the second sample stream.

Abstract: ABSTRACT A packaging and cooling assembly for integrated circuit chips includes a base for reception of one or more circuit chips, and a combination heat sink and cover for attachment to the base.  The circuit chips are mounted circuit side down on the base, and include flexible lead frames for attachment to bonding pads on the base. Compliant cushions that generally conform to the shape and size of the chips are held loosely between the circuit sides of the chips, and the base.  The heat sink engages the back sides of the circuit chips when it is attached to the base. This causes the chips to compress the compliant cushions, thereby holding the chips firmly in position, and forming a high thermal conductivity interface between the chips and the heat sink.  To further enhance the heat transfer characteristics of the interface, a thin film of fluid is coated on the back sides of each chip to fill in the microvoids which result from asperity contact of the heat sink and chip mating surfaces.  A sealing gasket is provided between the heat sink and the base to form a protective enclosure for the chips. Intermediate housings or heat spreader structures may alternatively be disposed between the chips and the heat sink.

Abstract: The invention relates to a device for marking electric wires or the like and presents a solution of the problem of making it possible to use one and the same marker alternatively for permanent or temporary mounting. In the first case the marker is threaded over the wire in the direction of the longitudinal axis of the wire, whereas in the latter case it is mounted by a displacement in the radial direction of the wire and retained by a snapping action. The marker which consists of an elastic plastic material comprises an outer portion shaped like an inverted U and an inner portion having two lateral legs. According to the invention the space for receiving a wire on which the marker is permanently mounted is defined between said inner and said outer portion whereas a space for receiving a wire on which the marker is temporarily mounted is defined between the legs of the inner portion.
