Abstract: PROCESS FOR IMPROVING POLYMER FIBER          PROPERTIES AND FIBERS PRODUCED THEREBY                  Abstract of the Disclosure A method is provided for treating polymer fibers or fibrous structures made thereof containing active hydrogen atoms to permanently improve the antistatic, hygroscopic, dye receptive and soil release properties of the fibers and structures.  The method involves heating a fiber to a solution containing acid and an unsaturated monomer.  The pH of the solution is allowed to stabilize and the monomer concentration is allowed to reach uniform dispersal and penetration in the filament bundle.  The solution is then maintained at a certain treatment temper-ature.  The treatment temperature utilized depends on the type of fiber treated.  A fiber containing amine groups is treated at a temperature of between about 75°C and about 100°C; a fiber containing hydroxy groups is treated at a temperature between about 85°C and about 100°C. Initiator is then added thus allowing graft polymerization to occur.  The fibers are then allowed to remain in solu-tion to allow substantial polymerization to occur.

Abstract: Abstract of the Disclosure A switch module includes a base and an array of one or more switches spaced adjacent to one another on the base.  Each switch includes a fixed contact as well as a moving contact and supporting arm therefor.  All of the switches in the array are formed from a single planar conductive blank composed of a closed frame and first and second sets of opposed elongated cantilevered panels extending from opposite sides of the frame, one set of panels forming the stationary contacts and the other set of panels forming the moving contacts and supporting arms therefor.  The blank is deformed to move all of the corresponding stationary and moving contacts into overlapping relation and to give bias to all of the contact arms so that they urge the associated moving contacts into or out of engagement with the corresponding fixed contacts.  All of the switches while they are still integral parts of the deformed blank are mounted to the base so that the relative positions on the base of all of the switch contacts are predetermined by their positions in the deformed blank.  Finally, the deformed mounted blank is severed at selected locations to electrically isolate some or all of the switch contacts mounted to the base.  Various blanks for making the switch module are disclosed as is the method for doing same.

Abstract: Abstract of the Disclosure An image data conversion technique is disclosed in which the picture image data is converted into a runlength code in order to compress the bit information to be transmitted.  The invention achieves a shorter conversion time than prior systems while at the same time ensuring that a smaller conver-sion table than required by other prior systems can be used.  Particular use is made of a character code/character pattern converter.  This latter circuit includes a character pattern generator which generates a character pattern signal corresponding to the character code.  A converter converts the character pattern signal to a runlength code and this is then multiplied by a character enlargement coefficient.  A character interval is then added to the enlarged runlength code and an output signal obtained.

Abstract: ELECTRICAL CIRCUITS AND COMPONENTS                       ABSTRACT          It is discovered that a liquid dispersion of polymer powder particles, predominantly of polyvinylidene fluoride, simultaneously:  a) can suspend electrical property additives, such as crystalline, hard, dense particles of generally spherical shape, uniformly in desired concentrations; b) while containing a useful concentration of any of a wide range of such particles, can be deposited by high shear transfer to a substrate in accurately controllable thickness and contour; c) when so deposited can be fused into a continuous uniform film which has low absorptivity, e.g., of moisture, and acts as a barrier film; d) where desired, can, as one layer, be fused with other such layers, containing other electrical property additives, to form a monolithic electrical component; and, e) in general, can meet all req??rements for the making of many useful electrical circuit components, including electroluminescent lamps, by printing and coating techniques with a high degree of accuracy and controllability.  The discovery can be employed to form products that are highly resistant to ambient heat and moisture.  The invention provides, in particular, circuit components and electroluminescent lamps that contain light-emitting phosphors and covering layers which have unusual durability, moisture resistance, and light transmissivity, using simple screen printing and doctor blade coating techniques.

Abstract: ABSTRACT        A belt tensioning device for an endless drive belt for a vehicle accessories drive system. A bracket is adapted to be mounted on an engine in a stationary position adjacent the drive belt and has lever means pivotally mounted thereon.  An idler pulley is rotatably mounted on the lever means and is movable into belt tensioning engagement by a torsional coil spring telescopically mounted about the pivot for the lever means.  The pulley is mounted so that a radial center line through the peripheral belt receiving surface of the pulley also passes generally through the center of the lever means pivot to reduce the frictional force exerted on the pivot.  A brake band ring is mounted between the bracket and lever means and is biased by the tor-sional spring into a camming engagement with the lever means to provide a damping force when the lever means attempts to move in either a belt tensioning or non tensioning direction.  The damping force is proportional to the belt tensioning force through-out the tensioning range of the belt tensioner since the same coil spring provides both forces.  The brake band has angled surfaces which move along complementary angled surfaces formed on the mounting bracket to provide an adjustable camming engagement therebetween.

Abstract: Abstract Referring to a reactor for industrial plants, e.g. for an ammonia synthesis plant, comprising several catalyst beds in series to be charged by a radial gas flow, the object is to provide for a uniform gas flow through the catalyst bed along its entire height, because otherwise different space velocities have to be faced within the catalyst bed involving irregularities in the reaction.  The problem is solved by the fact that the cross section of the annular space for the effluent reaction gas flowing in axial direction is equal to or larger than the cross section of the annular space for the influent fresh gas flowing in axial direction.

Abstract: ABSTRACT OF THE DISCLOSURE A  fuel  processor device particularly useful for separating water and other impurities  from  diesel fuel.   The fuel processor according to the  invention  features  a  vertically elongated  housing where  fuel  is initially transmitted wherein water  and heavy  particulates  are removed therefrom.   The  housing  includes  a  manually  or automatically actuated drain  valve, a fuel inlet fitting, and an optional  heating device.  After passing  through  the  housing,  the  fuel  is conducted to  a  particulate filter, preferably of the spin-on  variety, which  is  mounted  to  a  head which   communicates with  a  fuel  processing housing.   The  filter  is positioned  in  side-by-side  relation  with the fuel processor housing.  A first  embodiment  according  to this invention  describes  the  use  of  a horizontal elongated head which  communicates  the  upper  portion  of  the housing with a filter mounting pad.  A second embodiment of this invention is substantially  identical with the first except that the unit is invented such that the lower  portion of the housing forms the horizontal extending filter mounting pad.  Fuel processors  according  to this invention provide excellent water separation and particulate filtration  performance  and are particularly adapted to be installed where vertical height limitations  are imposed.

A  discrepancy  is  indicative  of  tampering  with  the register  display.    Any  tampering with the optical encoders or the metering  mechanism can be detected by comparing the present position of  the  encoders  with  that of a previous position and generating a signal   indicative   of   tampering  when  these  positions  have  a predetermined relationship to each other.
