Abstract: ABSTRACT OF THE DISCLOSURE      An interference warning device for an oil well drill-ing rig having a derrick, traveling equipment, a racker arm,  and a block retractor.   Fluid activated sensors provide electric signals when the traveling equipment is within a selected vertical distance from the racker arm, when the racker arm is within a selected horizontal dis-tance from the vertical axis of the derrick, or when the block retractor has extended the traveling equipment to within a selected distance from the fully extended po-sition.  The operator is informed when any one of the sensors is activated, cautioned when any two of the sensors are activated,  and warned when all three sensors are activated.  The drawworks may be braked when all three sensors are activated.

Abstract: A B S T R A C T       A totally sealed and slightly inflated package containing granular, free flowing fresh baker's yeast having excellent physical and biochemical preservation characteristics. A process for the production of the same comprises the steps of selecting a plastic laminate for the package that is totally or practically totally impervious to oxygen,carbon dioxide and water vapor, filling the package with yeast containing less than 70% moisture and sealing the package in a manner so as to totally or almost totally prevent the inclusion of any significant volume of air. The sealed package is subjected to time and temperature conditions under which a desireable volume of carbon dioxide is generated in situ through auto-fermentation. The time and temperature conditions have no deleterious effect on the leavening activity of the yeast.

Abstract: Abstract A method of securing a window (12) of crumbly material in the end of a tube (10) so as to effectively prevent leakage during temperature cycling, first involving the step of selecting a window (12) having a small clearance when placed inside the end of the tube (10). Any conta-mination is removed from the periphery of the window (12), and then a thin metallic layer (22) that will ac-cept nickel plate is vapor deposited around the periphe-ry of the window (12). Subsequently, a hoop (26) of ten-silly stressed nickel plate is applied over the thin me-tallic layer (22), after which the window (12) and tube (10) are sweated together by the application of suitable amounts of solder (24) and heat. Significantly, the hoop (26) of nickel serves to keep the window (12) in conti-nuous compression, such that leakage between the window (12) and tube (10) is effectively prevented.      Fig. 3

Abstract: IMPROVED FLOW CONTROL BETWEEN A DATA            TERMINAL AND A HOST COMPUTER SYSTEM            Abstract An improved operating system for increasing the data transfer rate between a host computer and a data terminal while still allowing the utilization of flow control.  The system is useful in multi-user computers where the connected data terminals are communicating large amounts of data with the host computer system. During the transfer data from the host computer to the terminal, the operating system controlling the host computer first disables the use of the designated characters as flow control characters, starts the transfer of information to the terminal, performs operations to determine whether or not the terminal is approaching the point where it can no longer receive data, and enables the utilization of the designated characters as flow control characters when the terminal reaches the latter point.  The operation system thus allows the data terminal to control the amount of characters received and a similar operation is performed during the transmitting  of characters from the data terminal to the host computer system.

Abstract: A device for detecting a thickness variation of a piece of fabric passing under the presser foot of a sewing machine. The device includes a transmitter and receiver between which the fabric passes. The receiver stores maximum and minimum signals in memory units generated when the fabric passes between the transmitter and receiver. A computing unit calibrates the thresholds as a function of the stored maximum and minimum signals. A comparator compares the incoming signals with the calibrated thresholds and sends a signal to a logic unit to control the sewing operations accordingly.

Abstract: ABSTRACT          Process for scrubbing exhaust gases from diesel engines using filter cartridges of open pore ceramic foam are such that the filter cartridges are situated in the exhaust gas stream such that the exhaust gases strike the filter cartridge end and flow through it parallel to its central axis. As a result the amount of soot deposited is greatest in the part of the car-tridge first meeting the inflowing exhaust gases, and decrea-ses rapidly with increasing throughput, consequently the low efficiency part contributes greatly to the undesired back-pressure.            The proposed process, in which the exhaust gases flow through the most efficient part of the filter cartridge made of open pore ceramic foam, is such that the exhaust gases flow essen-tially transverse to the longitudinal axis and thus does not exhibit these disadvantages.            A filter cartridge of open pore ceramic foam for carrying out the press according to the invention comprises a cylinder (4) with cylindrical shaped opening (5) the central axis of which coencides with that of the cylinder (4). The opening (5) can be closed at one end.
