IPC: B23Q35/20
Filed: 1990-11-20
Abstract: A method of and a device for working a longitudinal groove in natural wall logs. Drawbacks of the prior art methods of industrial working of logs are uneconomic use of raw material and unsuitability for working a longitudinal groove in a natural log. Up till now, only a manual working of a dead log in particular has been possible. The object of the invention is to eliminate these drawbacks. By means of the working method and the device of the invention, the form of a lower log (9) is copied to the longitudinal groove of an upper log (8) by using a parallel mechanism (27, 28, 30;  24, 29, 33) mounted on bearings on a carrier (22) moving on guides (21) parallel with the logs (8, 9). Each half of the longitudinal groove is worked independently.

Title: Methods and compositions for promoting immunopotentiation
Inventor: BLUESTONE JEFFERY A
IPC: C07K19/00
Filed: 1990-10-26
Abstract: This invention discloses immunopotentiating agents which stimulate an immune response. These agents are categorized into single agents that act directly, adjuvants added concurrently with the agents, or heteroconjugates. Heteroconjugate agents elicit or enhance a cellular or humoral immune response which may be specific for an epitope contained within an amino acid sequence. Enhanced hematopoieses by bone marrow stem cell recruitment was also a result of administering some of these agents. Examples of immunopotentiating agents include monoclonal antibodies and proteins derived from microorganisms (e.g., enterotoxins) which activate T cells.  One method of treatment disclosed uses only the immunopotentiating agent to stimulate the immune system. Another uses adjuvants in combination with the agent. A third method employs heteroconjugates. Heteroconjugates comprise: (a) an immunopotentiating protein which is characterized as having an ability to stimulate T cells;  and (b) a second protein having an amino acid sequence which includes an epitope against which a cellular or humoral response is desired. This invention also relates to a method of preparing the heteroconjugate, and to a method of stimulating the immune system in vivo in a novel way. One route of stimulation is to activate T cells, in some instances, specific subsets of T cells, by administering heteroconjugates containing an immunopotentiating protein and a second protein, to mammals. For this method of treatment, the second protein in the heteroconjugate is derived from abnormal or diseased tissue, or from an infectious agent;  alternatively, the second protein is produced synthetically by standard methods of molecular biology. Sources of the second protein include tumors, viruses, bacteria, fungi, protozoal or metozoal parasites.  Monoclonal antibodies or T cells prepared from mammals whose immune systems have responded to administration of the heteroconjugate may be produced and administered to induce passive immunity.  A method of preparing a hybridoma which secretes said monoclonal antibodies and use of these monoclonal antibodies and T cells, are also disclosed. This invention is also directed to a vaccine comprising the heteroconjugate.

IPC: H04M9/08
Filed: 1992-08-12
Abstract: In an echo canceller having PCM interfaces used in a PCM telephone circuit, an echo estimator (65) is coupled with a receive path through a linear code converter (632) for measuring a linear receive input signal, and a subtracter (7) is inserted after a linear code converter (631) in a transmit path for cancelling an echo component in a linear transmit input signal. The same procedure as that in a conventional echo canceller is performed in a divergent situation in the echo estimator (65) in which a large step gain is assigned, and in a convergent situation in the echo estimator (65) in which a relatively small step gain is assigned, a non-linear quantization processor (27,271) is inserted between the subtracter (7) and the echo estimator (65). The non-linear quantization processor (27,271) produces a new echo estimate containing a quantization noise, based on an echo estimate which is derived from the echo estimator (65). The new echo estimate can cancel not only the echo but also the quantization noise in the linear transmit input signal. The echo canceller having the non-linear quantization processor (27,271) can achieve a high echo return loss enhancement even for a multi-linked PCM channel.

Title: Intracranial pressure monitoring system
Inventor: BECKMAN RONALD B
IPC: A61B5/0215
Filed: 1991-02-12
Abstract: A catheter assembly (20) for measuring a fluid pressure in a body cavity includes an optical converter (39) responsive to an electrical power source for energizing a light-emitting diode (45) which has drift characteristics which vary in response to temperature. An optical sensor (22) is adapted to receive the light from the light-emitting diode (45) and to provide a measurement signal indicative of the fluid pressure in the cavity. This measurement signal has undesirable characteristics related to the thermal drift characteristics of the diode. A detection circuit (55) detects the measurement signal and provides an output signal indicative of fluid pressure in the cavity. A special filter (63) is included in this detection circuit (55) which has optical characteristics that substantially offset the undesirable characteristics of the measurement signal, so that the output signal is substantially independent of the temperature of the diode. A power conversion circuit (36) enables the assembly to be energized by an excitation voltage which is provided in several different forms by various monitors.
