Inventor: JOHANSON JERRY R
IPC: B65G69/20
Filed: 1991-04-11
Abstract: Apparatus for densifying particulate solids and for removing air from the solids includes a screw feeder that conveys the material through a recirculation chamber, then into a high pressure shroud that is closed at its downstream end by a preloaded cover in yieldable sealing engagement with the downstream end of the high pressure shroud.  In a preferred embodiment, the high pressure shroud includes a perforated section that extends upstream into the recirculation chamber so that as the particulate material is compressed by the screw in the high pressure shroud, air and some of the particles are expressed through the per-forations and are contained by the recirculation chamber which directs the expressed particles downward into the screw which once again pushes them into the high pressure shroud.  When the pressure in the high pressure shroud exceeds the preloading pressure applied to the cover at the down-stream end of the high pressure shroud, the particulate material emerges from the shroud in a compacted and deaerated condition.  The apparatus may also be used to replace a first entrained gas a second entrained gas, while at the same time providing a desired degree of densification.

Patent CA-2052813-A1 (CA)
Inventor: GREULICH KENNETH R
IPC: B42D15/00
Filed: 1991-10-04
Abstract: The creation and ordering of custom business forms is simplified for short-run orders, allowing the end user of the business form to design and transmit the order on a personal computer.  Using appropriate design software, the business form is first designed, and then electronically transferred into a second software program which allows for the selection of a number of business form parameters, and also includes order parameters including quantity and delivery options.  The business form parameters from the design software are automatically transferred to the ordering software, and any remaining parameters that must be selected are then selected in a sequence, the order quantity and delivery information is inputted, and the price is calculated, and then the custom business form and order are transmitted in machine form to a second computer remote from the first computer.  At the second computer a confirmation of the order is produced, and the order is evaluated to determine where the best facility to print it is.  The order is then electronically transferred to the printing location, and after printing it is shipped.  The particular manner of highlighting and/or pictorially illustrating the options selectable, and a number of the particular parameters to be selected -- such as the edge along which multipart forms are to be attached -- are controlled for optimum utility.

Title: Production and secretion of proteins and polypeptides by yeast
Inventor: THOMAS DAVID Y
IPC: C12N15/81
Filed: 1991-12-19
Abstract: ABSTRACT OF THE DISCLOSURE           A cDNA copy of the M2 dsRNA encoding the K2 killer toxin of Saccharomyces cerevisiae was expressed in yeast using the yeast ADH1 promoter.   This construct produced  K2-specific  killing  and  immunity  functions.          Efficient K2-specific killing and  immunity  functions.          Efficient K2-specific killing was dependent on the action of the KEX2 endopeptidase and KEX1 carboxypeptidase, while K2-specific immunity was independent of these proteases. comparison of the K2 toxin sequence with that of the K1 toxin sequence shows that although they share a common processing pathway and are both encoded by cytoplasmic dsRNAs of similar basic structure, the two toxins are very different at the primary sequence level.   Site-specific mutagenesis of the cDNA gene establishes that one of the two potential KEX2 cleavage sites is critical for toxin action but not for immunity.  Immunity was reduced by an insertion of two amino acids in the hydrophobic amino-terminal  region  which  left  toxin  activity  intact, indicating an independence of toxin action and immunity.

Filed: 1992-01-03
Abstract: An RF repeater arrangement for use in a wireless telephone system has a number of handset interface parts, each provided with a transmit section for transmitting a signal to a wireless telephone handset, a receive section for receiving an off-air signal from the wireless handset and an energy detector fordetecting the energy level of the received off-air signal and providing a control signal corresponding to such energy level. The control signal is employed for inhibiting the transmit section when the energy level of the received off-air signal is below a predetermined value. Thus, each handset interface part can determine when a channel is occupied and avoid transmission on that channel, so that only the geographic area around the occupied handset is subject to interference from the occupied channel.
