Abstract: A novel organic amine-impregnated activated carbon composition is disclosed which may be used in breathing gas filters to enhance removal of various toxic perfluorocarbons. Three processes for impregnating activated carbon with organic amines are also disclosed.      One of these processes comprises the steps of placing the amine in contact with substantially dry activated carbon, subjecting the carbon and amine to an environment devoid of oxidizing gases or vapors (such as oxygen gas), and then heating the carbon and amine for an extended period while maintaining this oxidizer-free environment. Pretreatment procedures to enhance both the shelf-life and service-life of the amine-impregnated activated carbon are also disclosed.

Inventor: TOBIAS MARC W
IPC: B60R25/02
Filed: 1993-07-05
Abstract: A mechanical anti-theft device of the type applied to the steering wheel of an automotive vehicle which automatically ratchets to it's applied position without necessity of key lock actuation is provided with several security enhancing features which cumulatively prevent or make the device exceedingly difficult to unlock using conventional burglary tools or lock picking techniques. The features include configuring the ratchet teeth of the telescoping rod member in a way which minimizes any. attempt to deactivate the lock unless the key is used. In combination with the ratchet teeth configuration, the lock pawl mechanism is configured to include an arcuate, transversely extending apex edge line or surface which cooperates with or is sized to be coincident with the rod members circumference to prevent a wedge, shim or pick from being readily easily inserted between pawl and ratchet tooth to force a retraction of the pawl.

Title: Conducting plastics material and a method for its preparation
Inventor: KARNA TOIVO
IPC: H01B1/16
Filed: 1993-08-06
Abstract: When using as a plastics material a polyaniline which has been doped with a protonic acid, the difficulty is how to combine the melt-processability and neutrality of the material. A well processable, with a protonic acid doped polyaniline has heretofore always been so acidic that it has disturbed both the processing apparatus, and the environment as a finished product. It has now, anyhow, been invented a process for the preparation of a plastics material which is based on a doped polyaniline, wherein during or after bringing in contact a polyaniline or a derivative thereof and a protonic acid also a metal compound is admixed. The metal compound is preferably first reacted with a first acid, whereupon the obtained product is brought together with a blend or reaction product formed by a polyaniline or a derivative thereof and a second protonic acid. In the mentioned process as the metal compound e.g. zinc oxide is used, as the first acid preferably the same acid as for the second protonic acid, i.e. dodecylbenzenesulphonic acid, is used. The plastics mixture thus prepared is preferably brought together with a thermoplastic polymer such as a polyolefin, wherein a neutral, plastic, stabile plastics material having a low percolation threshold is obtained.

Filed: 1994-07-07
Abstract: An expandable and contractible tubular cell window covering includes a plurality of contiguous cells which have been bonded together to form a wavy or undulating pattern along the length of the cells.  The undulating or wavy patterns can be created by initially stretching the cells  before  bonding  adjacent  cells  and  subsequently releasing the stretch so that the fibers engaged with the bonding medium remain in a stretched or separated condition while the remaining fibers are relaxed.  The cells can also be bonded with an adhesive that expands on curing to create the same effect without having to prestretch the fabric before applying the bonding medium.  In a third embodiment of  the  invention,  adjacent  tubular  cells  are  bonded together with curved lines of adhesive which again create an undulating or wavy configuration along the length of each tubular cell.   The methods for forming the window covering is also disclosed.

Title: Automatic bar code symbol reading system and method of reading bar code symbols using the same
Inventor: ROCKSTEIN GEORGE B
IPC: G06K17/00
Filed: 1994-09-26
Abstract: Disclosed is a fully automatic bar code symbol reading system having at least one automatic (i.e., triggerless) portable bar code symbol reading device, and an associated base unit positioned within the data transmission range thereof without a physical wiring connection thereto.  After each successful reading of a bar code symbol,  the bar code symbol reading device automatically produces symbol character data  representative  of  the  decoded  bar  code  symbol, synthesizes a group of data packets each containing the symbol character data, and then transmits the synthesized group of data packets to the base unit.  Upon the successful receipt of one of the transmitted data packets and the recovery of symbol character data therefrom, the base unit generates  an  acoustical  acknowledgement  signal  that  is perceptible to the user of the bar code symbol reading device and indicates the transmitted symbol character data has been successfully received.  In typical applications, a plurality of such bar code systems are used in physical proximity with each other, such as in conventional retail point-of-purchase (POS)  environments.    In  accordance  with  the  present invention, radio frequency(RF) carrier signals of the same frequency are used by each hand-supportable bar code symbol reading  device  to  transmit  groups  of data  packets  to respective base units.  Data packet interference at each base unit is minimized during data packet reception by using a novel  data  packet  transmission  scheme.    In  accordance therewith, each bar code symbol reading device transmits the data packets in each of its data packet groups with a unique time delay imposed therebetween, thus creating data packet transmission "slots" or "windows" on the time domain, during which other groups of data packets may be transmitted from neighboring bar code symbol reading devices and received at their respective base units without data packet interference. Each base unit in the resultant system is also able to distinguish  data  packets  associated  with  consecutively different bar code symbols read by its mated bar code symbol reading device.  This capability is provided by using a novel data packet encoding scheme during data packet synthesis, and a novel data packet decoding scheme during data packet reception   and   symbol   character   data   recovery. Significantly, the bar code symbol reading system of present invention eliminates the need for electromagnetic signal receiving and processing circuitry aboard each portable bar code symbol reading device.  Advantageously, the automatic bar code symbol reading system of the present invention can be inexpensively manufactured, and reliably operated with a significant reduction in battery power consumption which is critical  in  most  portable  bar  code  symbol  reading applications.
