Abstract: ABSTRACT            Tobacco product, consisting of a pre-portioned tobacco supply      surrounded by cigarette paper          of tubular shape. The tobacco supply is configured as a dimensionally stable tobacco strand     , which is matched to the tobacco charge of the finished cigarette and is unsmokable by itself but consists completely of smokable material, and it is provided for the self-making of either filterless or filter-tipped cigarettes. Pre-ferably, the tobacco supply      comprises an air permeable strand wrapper      of smokable material, e.g. of tobacco sheet material. To facilitate insertion of the preformed dimensionally stable tobacco strand      into a prefabricated tubular cigarette paper wrapper      , a funnel-like sleeve      is provided whose smaller-diameter end      is adapted to be joined to the open end of the tubular cigarette paper wrapper     . Through this inserting funnel      the tobacco strand      may be passed without difficulty into the tubular cigarette paper wrapper     .

Abstract: FIBER OPTIC FREQUENCY SHIFTER               Abstract of the Disclosure This invention relates to fiber optic frequency shifters  for  producing  optical  signals  of  a  desired frequency range for input to a device such as an optical rotation sensing system.   The rotating birefringence  is created in a length of fiber optic material, which has the effect of a rotating half-wave plate upon an input optical signal.   The length of fiber optic material may have a jacket of either an electrostrictive or a magnetostrictive material  formed  thereon  such  that  application  of  an appropriate field to the jacket compresses the enclosed fiber to induce  birefringence  therein by means of  the photoelastic effect.   A half-coupler having a block of electro-optically  active birefringent  material  adjacent the  interaction  region  combined  with  an  electrode configuration  and  circuitry  for  producing  a  rotating electric  field  in  the block  also  produces  a  rotating half-wave plate frequency shifter.   The evanescent field of light propagating in the optical fiber interacts with the rotating birefringence  and experiences  a  frequency shift.  The invention also includes feedback circuitry for processing  the  optical  output  of  fiber  optic  rotating half-wave plates to maintain the intensity of components in the output signal having the carrier frequency below a threshold value.

Abstract: ABSTRACT OF THE DISCLOSURE          An apparatus and method for measuring the torque of a rotating shaft wherein two gears are placed adjacent to each other on the shaft but are fixed to the shaft at a predetermined distance apart such that the twist in the shaft causes an angular displacement of one of the gears with respect to the other.  Each gear is provided with a number of teeth equally spaced thereon, one such gear having a different number of teeth than the other gear and a unique tooth to act as a reference point thus establishing a vernier relationship between the two gears.  A single sensing means is positioned at the interface between the adjacent gears and detects the amount of overlap for each pair of gear teeth (one from each gear) as they rotate thereby.  Each pair of teeth will be in a different degree of alignment with one such pair being in nearest alignment.  As the torque twists the shaft, the location of the pair of teeth in nearest alignment will move circumferentially around the interface between the gears.  The output of the single sensing means is transmitted to electronic processing means which compares the degree of alignment of each pair of teeth in each rotation of the shaft, thus identifying the location of the reference point and the pair of teeth in nearest alignment.  The distance between these two points is related to the torque being transmitted by the shaft.

Abstract: Abstract An improved method for erasure of an image target in a CCRT projection system includes the steps of projecting a defocused electron beam onto the target forming a scan line, establishing an energy level below the erase threshold to prevent erasure of any portion of the target within the single line, scanning multiple lines across the full target, and overlapping the scan lines sufficiently to provide integrated heat energy to cause erasure.  The energy level is established at about 75% of the erase threshold or about 0.3 joule/cm2  The power is preferably set at 30 kV and 400 microamps with a single scan line being established at 0.056 inch.  Preferably, the scan line is set to overlap 5-12 times to cause erasure, with the optimum being approximately 8 overlaps.  In the related CCRT set up of the erasure mode, after overlapping the scan lines, the energy level is gradually increased until the integrated heat energy is sufficient to cause erasure.  With these parameters established, the desired erasure of the target is assured when needed.
