Title: Method for obtaining a culture medium from plant sap
Inventor: KIEL PAULI
IPC: C12N1/20
Filed: 1992-02-27
Abstract: The procedure involves heat treatment of the plant juice, first in a temperature x time interval from 55 ·C x 24 hours to 120 ·C x 10 min., whereafter the plant juice is cooled to 50 ·C - 60 ·C  and the pH value is set at 7.5 - 8.5 by addition of a base.  Hereafter the plant juice is converted by enzymic hydrolysis by means of proteolytic enzymes such as proteases and peptidases, while keeping the pH value constant at 7.5 - 8.5 by continuous addition of base until the hydrolysis is over. By the procedure a medium is formed which is well suited as a nutritive substrate for vitamin and amino acid demanding micro-organisms, which form organic acids or amino acids. By the procedure it is possible in a cheap and simple manner to convert plant juice to organic acids or amino acids.

Patent CA-2105964-A1 (CA)
Title: Accumulator having surge control
Inventor: STEEBER DORIAN F
IPC: B65G47/51
Filed: 1992-03-16
Abstract: Surge control or accumulator apparatus and corresponding method include a relative downstream shift operation of a particular distance in combination with stopping the inflow of products at a particular upstream point such that product shear points are positively eliminated for accumulator product removal operations. An infeed stop mechanism (10) traps the leading edge of an appropriate package (14) while permitting other packages to be advanced beyond known shear points during the downstream shift operation. The infeed stop mechanism (10) uses a slidable stop plate (32) and upstream therefrom a wedge shaped guide member (34) to cooperatively trap the leading edge of an approaching product in a pinchless operation, i.e., without applying clamping force to such product or to other products permitted to pass by the slidable stop plate.  An outfeed mechanism (82) includes an adjustable downstream shift feature (98) for controllably shifting a row of products to be removed from a conveyor. The adjustable amount of downstream shift is related to the nominal length of individual products advancing along the conveyor and an additional predetermined distance added thereto. By shifting products downstream, for example, by about 150 percent of the nominal product length while setting the pinchless infeed trap, an appropriate row of products for removal are isolated from potential shear points, without depending on the precise number of products contained in such row. The surge control or accumulator method and apparatus results in safe handling of products regardless of the cumulative effect of unpredictable variations in the sizes of individual products being handled.

Title: Blood pack labels
Inventor: LEUENBERGER MARK
IPC: A61J1/14
Filed: 1993-02-09
Abstract: A label (12) for a blood pack (10) comprising a microporous plastic film including a matrix of interconnected pores for allowing gas to flow into and out of the blood pack (10) through a labeled area.

Filed: 1992-10-01
Abstract: ABSTRACT OF THE DISCLOSURE       A rotary kiln having a polygonal lining is disclosed for pyro-processing cement, lime, other minerals, as well as other materials.  Specifically, utilizing a polygonal lining of brick or a refractory or ceramic material having between 3 and 12 sides improves the heat efficiency or heat transfer between high-temperature gases and a burden of material to be processed by the kiln.  Such an efficient utilization of the gas heat is due to various factors which cause a larger amount of the burden to be more quickly exposed to the high temperature gases.  These various factors include increased tumbling, increased residence time, decreases degree of filling, and increased surface exposure.
Patent CA-2127043-A1 (CA)
Inventor: HEISMANN FRED L
IPC: H04B10/135
Filed: 1994-06-29
Abstract: The effects of polarization dependent hole burning and/or polarization dependent loss are reduced by modulating the state of polarization (SOP) of an arbitrarily polarized optical signal being launched into the transmission path periodically through a predetermined sequence of polarization states. The sequence of polarization states is selected such that on average the launched modulated signal excites substantially all possible polarization states with substantially equal probability, independent of the input SOP to the polarization modulator. In one exemplary embodiment, the SOP is modulated by a combination cascade of a rotating half-wave plate followed by a quarter-wave plate, which rotates at a different angular speed. In another exemplary embodiment, the SOP is modulated by a combination cascade of two variable phase retarders oriented at fixed angles of 0° and 45°, where the modulation frequencies of the two retarders are substantially different from each other.

Inventor: WEBSTER STEPHEN
IPC: H04B3/06
Filed: 1994-07-12
Abstract: ABSTRACT OF THE DISCLOSURE             A circuit for improving the performance degradation of a cable equalizer in a serial digital transmission system wherein the performance degradation results from parasitic coupling between the input and output of the cable equalizer. The circuit comprises a potentiometer which is coupled to the output of the cable equalizer. The wiper of the potentiometer is coupled to the input of the cable equalizer through a capacitor and a resistor. The capacitor produces a correction signal on the input which is proportional to the derivative of the output signal of the equalizer. The resistor coupled to the capacitor injects the correction signal into the input signal to reduce the effect of the parasitic coupling between the input and output of the cable equalizer.
