Granted: 1989-05-16
Abstract: A method and device for packaging essentially conical objects, particularly ice-cream cones, in individual wrappings. The ice-cream cones (1) are advanced with the aid of holder members (7). A web (11) of shrinking foil is folded over the cones. The ice-cream cones are advanced up to two wheels (12, 13) formed with cogs (14). On the cogs of one of the wheels two jaws (15) and a heating wire (16) are provided. The opposite wheel (13) is formed on its cogs (14) with a back-up surface. When the ice-cream cones reach the wheels (12, 13) the foil is compressed between the cogs (14) and burnt off by the heating wire while at the same time vertical edges are formed in the foil and fused together in such a manner that individual wrappings are formed about each ice-cream cone (1). Hot air is finally blown against the part of the wrapping that is positioned below the cone edge so that this part of the wrapping is shrunk onto the ice-cream cone and the wrapping securely retained thereon.

Granted: 1990-06-05
Abstract: PROCESS FOR THE PREPARATION OF LIQUID 2-HYDROXY-METHYLTHIOBUTYRIC ACID Abstract of the Disclosure A process for the preparation of 2-hydroxy-4-methylthiobutyric acid is disclosed. 2-Hydroxy-4-methylthiobutyronitrile is hydrolyzed with mineral acid to produce an aqueous hydrolyzate containing 2-hydroxy-4-methylthiobutyric acid and substantially free of unreacted 2-hydroxy-4-methylthiobutyronitrile and 2-hydroxy-4-methylthiobutyramide. 2-Hydroxy-4-methylthiobutyric acid is recovered from the hydrolyzate by extraction. Extraction may be carried out without prior separation from the hydrolyzate solution of any substantial fraction of solids present therein, and 2-hydroxy-4-methylthiobutyric acid may be recovered from the extract by steam distillation. The extraction solvent has a boiling point of between about 60°C and about 200°C, and the distribution coefficients for 2-hydroxy-4-methylthiobutyric acid between extract and raffinate, and between extract specimen and wash water, favor transfer to and retention of the acid product in the organic phase.

Title: Method and apparatus for treatment of biological tissue
Inventor: WELCH ALBERT B
IPC: A61N1/40
Filed: 1986-06-30
Granted: 1991-04-30
Abstract: METHOD AND APPARATUS FOR                 TREATMENT OF BIOLOGICAL TISSUE     ABSTRACT   The  treatment  of  biological  tissue  is  effected  by  a pulsed electric field induced by a time changing magnetic field produced by a magnetic coil or a plurality of magnetic coils.   These magnetic  coils are arranged in the area of desired treatment and respond to a driving current to induce the  pulsed  electric  field  into  the  localized  treatment area.   The driving current and concomitant magnetic  field generates an electric field waveform that has a first pulse in a positive direction having a selected value followed by a second pulse in a negative direction having a larger value than the first pulse, and in turn followed by a third pulse in the positive direction having a value on the order of the first pulse.  The apparatus for applying the driving current includes  switching  circuitry  for  energizing  the magnetic coils in pairs to induce a symmetrical distribution of the magnetic and electric fields  in the treatment area.   This achieves  time  averaged  uniformity  of  the  pulse  electric field in the tissue for applications such as stimulation of osteogenesis in long bone nonfusions.

Title: Tape feeding apparatus
Inventor: FRYE RICKY J
IPC: D05B29/06
Filed: 1986-12-23
Granted: 1992-03-17
Abstract: Abstract of the Disclosure TAPE FEEDING APPARATUS           Tape feeding apparatus is provided to feed patches of tape from a tape supply to a sewing location. The tape in question has short, resilient hooks firmly attached thereto extending from a first surface of the tape.  The apparatus includes a supporting device including parallel guides.  At least one of the guides is movable toward and away from the other to accommodate tapes of different widths.  The guides serve to guide the tape along a path from the tape supply toward the sewing location.  Intersecting the path is a one-way propulsion device which moves the tape only toward the sewing location.  At a location along the path between the one-way propulsion device and the sewing location is a severing device that severs one of the patches at a time from the end portion of the tape extending toward the sewing location.  A holding device holds the end portion of the tape during the severing of each patch.  An adjustable receiving device receives the patches, one at a time.  It includes first and second parallel sides, at least one of which is adjustable toward and away from the other to set the space between them according to the width of the tape and a third side perpendicular to the first two to receive the edge of the patch that previously consituted the end of the portion of the tape from which that patch was severed. The third side holds that edge in a predetermined position in the sewing location.  The receiving device is open along the fourth side facing the severing device.

Abstract: THERMAL PRINTING APPARATUS AND METHOD            ABSTRACT    A thermal printing apparatus and method are disclosed which allows a plurality of thermal print head elements to remain concurrently active, with each individual element being capable of remaining active for a time duration unique to itself and independent of burn times required by the remaining elements.          This individual element burn time control is obtained by the high-speed loading and reloading of the thermal print head shift register, with the contents of the individual shift register cells being the controlling factor.  Once the thermal print head element resistances have been dynamically measured, specific energies are derived for each element in the printhead by modulating the on time for each element, thus allowing grey scale printing and the like.

Granted: 1992-01-07
Abstract: ABSTRACT Prior to reaching the nozzle's exit, the belt is pressed from outward against the nozzle by means of a rail supported by springs whereby the mould is reliably sealed off under all working conditions. Pressing the belt against the nozzle can also be achieved by means of pistons or the direct hydrostatic and/or hydrodynamic effect of the coolant from the outside or through various combined measures.  In order to reduce friction and wear, the nozzle in the area of contact with the belt can be provided with a wear-resistant coating or wear-resistant inserts.  This sealing method enables a casting  process with  high metallostatic pressure, consequently resulting  in  a high quality product.

Abstract: Regulation of expression of genes encoded for in plant cell genomes is achieved by integration of a gene under the transcriptional control of a promoter which is functional in the host and in which the transcribed strand of DNA is complementary to the strand of DNA that is transcribed from the endogenous gene(s) one wishes to regulate. The integrated gene, referred to as anti-sense, provides an RNA sequence capable of binding to naturally existing RNAs, exemplified by polygalacturonase, and inhibiting their expression, where the anti-sense sequence may bind to the coding, non-coding, or both, portions of the RNA. The anti-sense construction may be introduced into the plant cells in a variety of ways and be integrated into the plant genome for inducible or constitutive transcription of the anti-sense sequence. A wide variety of plant cell properties may be modified by employing this technique.

The  system includes a dispersion transformer which receives light from  one of the  components,  compensates  for  or transforms the delay  distortion  of  the  various wavelengths  transmitted   through  the  system,   and provides  the  next  component  in  the  system with  a compensated or transformed light beam.  The dispersion transformer comprises means for receiving light from one  of  the  components  and dispersing/separating  the light  into a plurality of spatially separated beams which  are directed onto the  endface  of a multimode optical fiber.  The position of each beam on the end-face  of  the multimode  fiber  is  a  function  of  the velocity  with  which  the  light  that  forms  the  beam propagates through the transmission optical fiber.  The multimode fiber is characterized by a refractive index profile  and  a  shape which are  such  that  the modes excited  therein  are  propagated  therethrough  with appropriate  delays  to  generate  an  output  pulse  of desired width.  Dispersion can be reduced or increased. Light emaninating from the multimode fiber is coupled to the next adjacent component of the system.
