Abstract: TITLE OF THE INVENTION:  METHOD FOR LOADING AND LOADING DEVICE FOR A  PRESS FOR COMPRESSING STRUCTURAL ELEMENTS, ESPECIALLY FUEL CELL SKELETONS OF NUCLEAR            REACTOR FUEL ELEMENTS           ABSTRACT OF THE DISCLOSURE:    In  presses  for  compressing  fuel  cell skeletons of nuclear reactor fuel elements and other  structural  elements,   loading  is  made possible without the previously required change of position of the press shaft relative to the base body of the press and without at least partial removal of the cover of the press shaft.   The cross bar at which the counterpunch, respectively, the transfer shaft of the press is supported is provided with an opening.  Through the opening a feed channel which is slidable in the longitudinal direction of the press and which receives the fuel cell skeletons to be compressed is pushed into the press shaft, with the counterpunch, respectively, transfer shaft being removed from the press shaft.          The fuel cell skeleton is then pushed from the feed  channel  into  the  press  shaft  in  the longitudinal direction of the press by a slide.          In order to reduce the constructive length of the loading device, the insertion of the fuel cell skeletons  is  carried  out  in  two  advancing movements of the slide by providing a push plate rigidly connected to the slide and an advancing ram which is pivotable into the feed channel.

Title: Motion compensation encoding of a picture input signal into a picture output signal of a predetermined bit rate
Inventor: OHKI JUNICHI
IPC: H04N19/172
Filed: 1992-10-23
Abstract: Derived from a picture input signal and a motion vector signal in a block matching type motion compensation encoding device, a prediction error signal is quantized by a controllable quantizer into a quantized signal for encoding together with the motion vector signal.  Supplied with frame pulses, a controller produces a control signal with a predetermined value for making the quantizer quantize a zero signal instead of the error signal and with a different value for operating the quantizer merely as a forward quantizer.  An amount of encoded information is reduced when the predetermined value appears once in two or three frame periods.  For smoother movement of a movable part in reproduced pictures, the zero signal is not substituted in each duration in which motion vectors are either greater in magnitude, not identical with a representative vector, or less correlated with corresponding motion vectors in a previous picture for which the zero signal is not substituted.  Each duration may be an interval of time during which the error signal has a greater absolute value.  The controllable quantizer may be a combination of the forward quantizer and a selector controlled by the control signal to select the zero signal and either the error signal or an output signal of the forward quantizer.

Title: Protease catalyzed treatments of lignocellulose materials
Inventor: POKORA ALEXANDER R
IPC: A61P25/04
Filed: 1992-11-05
Abstract: Wood chips or wood pulps are treated at any stage of the papermaking process but preferably prior to delignification or bleaching with a protease enzyme to enhance fibrillation and/or the efficiency of delignification or bleaching. The proteases, pepsin and papain, promote the removal of lignin from wood, possibly through cleavage of the cell wall protein matrix. Wood pulps treated with proteases exhibit a higher degree of fibrillation than pulps not treated with proteases. Furthermore, the protease treatment produces a flatter fiber which improves paper smoothness derived from these fibers. The protease treatment may be combined sequentially or by admixture with treatment with a xylanase or ligninase.

Title: Targets for the prevention and cure of female breast cancer: bc534 and bc538, two reconstructed cdnas and encoded proteins antisense to the human tumour antigen p53 gene
Inventor: PREDDIE RICK E
IPC: C07K14/47
Filed: 1993-03-03
Abstract: ABSTRACT            The human tumour antigen p53, has been definitely implicated as a factor in inherited female breast cancer, but it is also likely  to  be  involved  in  breast  cancer  due  to  acquired mutations. In addition families carrying a mutated p53 gene have an extremely high rate of other cancers including brain tumours and sarcomas. The mode of action of p53 in the pathophysiology of breast cancer is not known. There is no treatment for the disease except surgery.  We reconstructed two cDNAs encoding proteins of 21 and 44 amino acids, respectively, which are 100 % homologous to regions on the antisense strand of human p53 gene. The expression of these proteins is repressed by the normal wild type p53 gene healthy in women; however, mutations, inherited or acquired,  in regions of the p53 gene which are crucial for maintaining repression could permit the expression of various levels of these two antisense proteins. The antisense proteins  are  potential  intracellular  activators  of  tumour causing and tumour associated proteins and of an inhibitor of 17 .beta. hydroxysteriod interaction with its receptor. The antisense relationship with p53 gene and the functions of these proteins make them ideal candidates for causative factors of p53 related female breast cancer and some other cancers which correlate with this disease in families carrying the mutated p53 gene. Since these proteins are not expressed in normal humans they are excellent targets for developing humanised antibodies against to prevent and cure the disease.

Abstract: In a system for enforcing the validity of circulating pointers, one or more target pointers are generated and compared to circulating pointers. If a pointer does not circulate through the system within a prespecified time, then a pointer has been lost and an error is reported. If a circulating pointer matches a target pointer, it is suppressed by being removed from the set of circulating pointers. Another timer is then set to determine whether further circulating pointers match a target pointer. If so, then multiple pointers to the same location are present and all duplicate pointers are suppressed. After expiration of the second time, the target pointers are added to the set of circulation pointers. This process repeats with new target pointers, so that the validity of the set of the set of circulating pointers is verified. <IMAGE>
Patent CA-2097609-A1 (CA)
Inventor: TAKESHIMA SHINICHI
IPC: F01N13/02
Filed: 1992-10-02
Abstract: An NO x absorbent (18) is disposed in an exhaust passage of an internal combustion engine and the exhaust gas is constantly made to circulate through the NO x absorbent (18) during the operation of the engine. The NO x absorbent (18) absorbs the NO x when the air-fuel ratio of the exhaust gas flowing into the NO x absorbent (18) is lean and releases the absorbed NO x when the air-fuel ratio of the exhaust gas flowing into the NO x absorbent (18) becomes the stoichiometric air-fuel ratio or rich. In the majority of the engine operation region, the lean air-fuel mixture is burned in the combustion chamber (3), and the NO x generated at this time is absorbed into the NO x absorbent (18). The air-fuel ratio of the exhaust gas flowing into the NO x absorbent (18) is periodically made the stoichiometric air-fuel ratio or rich, and the NO x absorbed in the NO x absorbent (18) is released, and simultaneously reduced.
