Title: Tissue culture method for asexual propagation  of pine trees and medium for use therewith
Inventor: SMELTZER RICHARD H
IPC: A01H4/00
Filed: 1979-09-25
Granted: 1982-08-17
Abstract: ABSTRACT OF THE DISCLOSURE     A tissue culture method for the asexual propagation of pine trees is described and claimed.  The method involves promoting adventitious buds from pine seeds by inoculating decoated seeds that have been previously stimulatee to germinate in a culture medium.  The methol enhances adventitious bud forma-tion and is operationally more practical than currently reported methods in that it is neither the consuming nor labor intensive.  Also, novel culture media are described and claimed which employ the interaction of the growth regulators benzylaminopurine and abscisic acid.

Abstract: ABSTRACT            METHOD & APPARATUS FOR ERROR CONTROL             IN ASYNCHRONOUS COMMUNICATIONS            Error control, in the form of a modulo 2 division re-mainder checksum is added to a packet of reformatted asynchronous characters prior to transmission over a data link connecting two data devices such as a host computer and a teletype terminal.  At one end of the link, data in asynchronous form, such as ASCII code, comprising seven data bits, start and stop bits, and a parity bit, is originated by one data device.  The start, stop and parity bits of each character are eliminated.  The remaining data bits for a selected number of characters are then grouped together to form a data grouping and the checksum and other control in-formation bits added, forming an information packet.          The information packet is then divided into sections or groups of eight bits.  Start and stop bits are added to each group, forming ten bit characters.  The ten bit characters are then transmitted over the data link in standard asynchronous format.  The process is carried out in reverse at the other end of the link, resulting in the other data device receiving the data in the form originated by the first data device.          Sophisticated error control techniques thus may be implemented in asynchronous communications without detrimentally affecting the data capacity on the channel.

Title: Solvent stretch process for preparing microporous  films from precursor films of controlled  crystalline structure
Inventor: SOEHNGEN JOHN W
IPC: C08L23/00
Filed: 1980-05-27
Granted: 1982-09-21
Abstract: Abstract of the Disclosure Microporous films having improved morphological structure are prepared by the "solvent stretch" method from an olefinic precursor film having a controlled crystalline structure.  The crystalline structure of the precursor film is controlled by preparing said film from an olefinic cry-stalline homopolymer characterized as having a melt index of about 3 to 20 in the absence of a nucleating agent and a molecular weight distribution ratio of about 3.8 to about 13.  In another embodiment the crystalline structure of the precursor film is controlled by incorporating a nucleating agent into the crystalline polymer resin from which the precursor film is prepared which thereby permits a reduction in the melt index of the polymer to about 0.3.

Abstract: 2195-37a ABSTRACT                    One of the two knife holder shafts in a cross cutter for webs of paper or the like is driven by a unit wherein a motor rotates the input shaft of a bevel gear drive whose output shaft drives or constitutes one shaft of a universal joint.  The other shaft of the universal joint is driven by the one shaft and transmits torque to the knife holder shaft or shafts by way of a step-up gear transmission and a clutch which allows for changes in angular positions of the knife holder shafts with reference to the universal joint.  An extension of the axis of the input shaft of the bevel gear drive intersects the axes of the shafts of the universal joint at the point where the axes of the shafts of the universal joint intersect each other.  To this end, the other shaft of the universal joint contains an elastically deformable but torsion-resistant insert.  The angle between the axes of the shafts in the universal joint can be changed by a carrier which is turnable about the axis of the input shaft of the bevel gear drive and rotatably supports the one shaft of the universal joint.

Abstract: Abstract of the Disclosure.           In an incinerator for chemical waste stored in barrels, hav-ing a primary and a secondary combustion chamber, the primary com-bustion chamber has a bottom section (1 ) and a top section (2), both provided with burners and air injection means (22, 38, 39, 40). The wall of the top section has a sluice port (4) for introducing a barrel (8), and within the top section there is provided a barrel holder (14) for receiving and holding such a barrel. The barrel holder (14) is mounted for rotation about a horizontal axis and can be operated for turning the barrel from upright to fully or partly inverted position and vice versa. Burning of the waste may take place either in the barrel in upright position, or upon turning of the barrel and drop-ping of its content into the bottom section (2), or a combination of both. Thereby optimum conditions may be created for incineration of waste of varying consistency, ranging from liquid to solid, and no manual handling of barrels or their contents is required. A maximum of automatization and economy can be obtained by providing, in the top section, a downwardly directed, vertically displaceable burner (22) combined with a consistency sensor (37) assisting in governing displacement of the burner (22) and turning of the barrel holder (14).
