Patent CA-2078364-A1 (CA)
Inventor: PFEFFERLE WALTER
IPC: C07K16/00
Filed: 1992-09-16
Abstract: The invention relates to a process for the fermentative preparation of amino acids, in which a strain of the genus Brevibacterium or Corynebacterium producing one or more amino acids is cultivated in a nutrient medium and the amino acid(s) is/are isolated from the culture fluid at the end of fermentation. The process is characterised in that after the vigorous growth phase, the bacterial culture has at its disposal a smaller quantity of assimilable carbon source than it could metabolize on the basis of the structure of the strain and the quantity of other necessary supplements provided in the nutrient medium. The process proceeds at a higher degree of conversion of the source of carbon used (sugar), and higher concentrations of amino acids) is/are obtained in the dry mass free from biomass, relative to the prior art.

Inventor: FOSTER RAYMOND K
IPC: B65G25/06
Filed: 1993-02-03
Abstract: Abstract of the Disclosure A lightweight reciprocating floor conveyor characterized by a plurality of elongated floor members which are divided into sets and groups.  Each set comprises at least two floor members in a common order and each group comprises one member from each set.   The groups extend side-by-side across the conveyor.  The floor members are supported on a conveyor frame, each for longitudinal back and forth movement, and a drive mechanism is provided for the floor members.  Separate linear hydraulic drive motors are provided for each set of floor members.   Each drive motor has a stationary portion and a movable portion, the stationary portion being connected to a stationary frame member and the movable portion being connected to a floor member of its set.  A plurality of transverse drive beams are provided, one for each set of floor members.  The drive beams are spaced longitudinally of the conveyor from the motors.  All of the floor members of each set are connected to the drive beam for the set.   Operation of each drive motor exerts a drive force onto a particular floor member to which the drive motor is connected.  This floor member will function as a longitudinal drive beam and will transmit the drive force to the transverse drive beam.  Each transverse drive beam will in turn transmit the drive forces to other floor members of its set.

Inventor: BOYD JOHN M
IPC: H01L27/04
Filed: 1993-03-24
Abstract: A method is provided for forming multi-valued linear resistors for an integrated circuit using a single mask level.  A plurality of trenches are defined in a substrate.  Each trench has contact regions of a specific lateral dimension and a narrower portion extending therebetween.  Successive conformal layers of a first dielectric layer, a first conductive layer of high resistivity and a second conductive layer of lower resistivity are provided to fill the trench.  The amount of the second conductive layer which fills the trench depends on the width of the trench.  The resulting structure is planarized, preferably by chemical-mechanical polishing to provide fully planarized topography.  Advantageously when the first and second conductive layers are provided from layers of undoped and doped polysilicon respectively, the trench dimensions control the amount of dopant incorporated in each region of the trench.  After annealing to diffuse dopant, the wider end contact regions are heavily doped to form contact regions, and the intermediate narrow portion of the trench is doped to a level dependent on the width of the trench, thereby forming a resistive element having a resistivity inversely dependent on the trench width.  The method is compatible with CMOS, Bipolar and Bipolar CMOS processes.

Title: A method of grouping links in a packet switch
Inventor: ERIKSSON THOMAS A
IPC: H04L45/24
Filed: 1993-03-16
Abstract: In a packet switch, which is intended for packets of constant length, and which, between switch ports, is divided into a number of nodes and transmission links, where the nodes carry out space selection and the transmission links offer point-to-point transmission between the nodes, link grouping is carried out.  More particularly, from multiple parallel physical links coming into the switch, link groups are produced, each in the form of a logical link with a bandwidth that is the sum of the bandwidths of the physical links included in the link group, said logical link being restored to outgoing parallel physical links from the switch. One or more link protocols are used according to which a label in the packet's header is made to describe a route that holds together the grouped links through the entire switch, such that bits in the label describing the route over a certain transmission link are the same for packets belonging to the same link group.

Inventor: ALLARD WILLIAM J
IPC: C12P21/08
Filed: 1994-03-10
Abstract: A method for aiding in the diagnosis of, and monitoring the progression or course of, lung cancer in a patient by measuring the amount of NCA 50/90 in a blood sample, e.g., serum sample, obtained from the patient. Measurement in a single sample of an amount of NCA 50/90 significantly higher than the mean amount of NCA 50/90 in the normal population is an indication of lung cancer in a symptomatic patient. The course of lung cancer can also be monitored by performing a series of specific immunoassays over time to determine changes in the level of NCA 50/90 in blood samples.      Increases in blood NCA 50/90 levels over time are indicative of a deteriorating condition whereas decreasing levels of blood NCA 50/90 over time indicate an improving condition.

Patent CA-2120617-A1 (CA)
Title: Muscle control and monitoring system
Inventor: GRANDJEAN PIERRE A
IPC: A61M60/839
Filed: 1992-10-30
Abstract: Apparatus and method for monitoring the performance of skeletal muscle used in a skeletal muscle powered cardiac assist system.  The longest term monitoring is performed by an oxygen sensor which determines the adequacy of circulatory support to the skeletal muscle. An adequately supported skeletal muscle can offer the desired cardiac assistance chronically. Insufficient support indicates that the skeletal muscle will easily fatigue if adequate vascularization is not achieved. If the circulatory support is chronically insufficient, the risk of ischemia becomes high and additional surgical intervention may be required. A somewhat shorter term concern is the adequacy of the conditioning needed to render a fast twitch skeletal muscle useful in assisting the slow twitch myocardium. A pressure transducer is used to measure conditioning sufficiency. A third type of monitoring provides an indication of changes in cardiac requirements utilizing an activity sensor. This indication of cardiac requirements may be used to vary skeletal muscle loading by adjusting duty cycle. The shortest term monitoring and control technique uses a temperature sensor to monitor efficiency of skeletal muscle cardiac assist. Efficiency may be improved by adjusting the phase relationship between cardiac contraction and skeletal muscle stimulation.
