IPC: A61N1/30
Filed: 1990-08-07
Abstract: An iontophoretic electrode has a plurality of ion transmitters for establishing electric field lines in an area and a plurality of receivers for accepting ions flowing along the field lines.  A plurality of shields  are  located  to  resist  ion  flow  between adjacent    transmitters    and    receivers.     The transmitters, shields and receivers are in at least a sequence  of  transmitter,  shield,  receiver,  shield. The electric field lines emanate substantially in one direction and return  in substantially the opposite direction.   The  transmitters  and  receivers  have matrix  structures  with  space  to  contain  ionic medication and electrolyte, respectively.   A support for  holding  a plurality  of  sequences  has  current carrying contacts exposed to connect the transmitters and receivers in circuit with a source of electrical power. The preferred method includes establishing an electric  field  with  lines  of  energy  between  a plurality of first and second conductors of ions and then passing ions along the energy lines between the conductors.     Thereafter   the    method    includes restricting  the  flow  of  ions  to  paths  between adjacent  first  and  second  conductors  and  then positioning  the  first  conductors  relative  to  the second conductors so that the energy lines  emanate from the first substantially in one direction return to  adjacent  second  conductors  in  the  opposite direction.

Abstract: Abstract (in connection with Fig. 1) 1.   A device  for supplying  packaging machines with packaging material.   2.1. The supply of packaging machines with packaging material is an intricate problem due to the efficiency of  the  packaging  machines,  in  particular  with  the production of cigarette packages. For the production of cigarette packages  consisting of  several  components, e.g. soft packages or hinge-lid packages, tin foil and paper or cardboard have  to  be processed as various packaging materials. The packaging material is supplied in the  form of bobbins  (tin foil  bobbins 13,  paper bobbins 14).   2.2. The packaging machine is equipped with two bobbin storages (23, 24) for the reception of tin foil bobbins (13) or paper bobbins (14). The bobbin storages  (23, 24) are supplied with the various bobbins (13, 14) by a common supplier, i.e. a floor-mounted supplier (15).   2.3. The various bobbins (13, 14) are removed from the bobbin  storages  (23,  24)  by means  of  a  transversal supplier (transport cog 51) and conveyed to a common downward delivering bobbin supplier (50). It transports the bobbins to superpositioned bobbin aggregates (42, 43).  Here the packaging material  is processed,  i.e. withdrawal from the bobbins.

Abstract: An attitude control device has a plurality of harmonic drive mechanisms of the hollow type, preferably first and second harmonic drive mechanisms. First and second rotational members are connected to the outputs of the first and second harmonic drive mechanisms. These rotational members have eccentric hollow portions which rotate eccentrically around the rotational axes of the harmonic drive mechanisms. A member to be driven is placed to extend through the eccentric hollow portions such that it is supportedly contacted with the inner surfaces of the eccentric hollow portions. In operation, the eccentric hollow portions are rotated relative to each other, whereby the member to be driven is controllably oriented to a desired direction.      The attitude control device can be employed as a drilling-direction control device wherein a rotational drill shaft is supported by inner surfaces of eccentric hollow portions of first and second rotational members. These rotational members are rotated by first and second harmonic drive mechanisms. By rotating the eccentric hollow portions, the rotational drilling shaft is changed in orientation from the vertical direction.

Filed: 1991-09-06
Abstract: Abstract of the Disclosure:     In a floating-point arithmetic unit for performing floating-point arithmetic of first and second input data which are represented by a floating-point representation and composed of first and second exponent parts and first and second mantissa parts, a shift amount calculating circuit comprises first and second subtracters (26, 27) supplied with lower (n + 1) bits of the first and the second exponent parts.  The first subtracter subtracts a first lower number (#EA1) from a second lower number (#EB1) to produce a first difference signal (RS1).  The second subtracter subtracts the second lower number (#EB1) from the first lower number (#EA1) to produce a second difference signal (RS1).  Supplied with the first and the second exponent parts, an exponent comparing unit (28) compares the first exponent part with the second exponent part to produce a comparison result signal (CP1, CP2, CP3, CP4).  Responsive to the comparison result signal, a first selector (31) selects one of the first difference signal and first and second value signals ("0", "64") as a first right-shift amount signal (SD1).  Responsive to the comparison result signal, a second selector (32) selects one of the second difference signal and the first and the second value signals as a second right-shift amount signal (SD2).

Title: Abrasive product having a binder comprising an aminoplast binder
Inventor: KIRK ALAN R
IPC: B24D3/34
Filed: 1992-01-30
Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to abrasive products having a resinous binder.  The abrasive products can be bonded abrasives, coated abrasives, or nonwoven abrasives.  In the manufacture of coated abrasives, the make coat and abrasive grains are first applied to the backing, then the size coat is applied, and finally, the construction is fully cured.  Generally, thermally curable binders provide coated abrasives with excellent properties, e.g., heat resistance.  In order to obtain the proper coating viscosities, solvent is commonly added to these resins. When polyester or cellulosic backings are used, curing temperature is limited to about 130°C.  At this temperature, cure times are long.  The long cure time along with the solvent removal necessitates the use of festoon curing areas.  Disadvantages of festoon curing areas include the formation of defects at the suspension rods, inconsistent cure due to temperature variations in the large festoon ovens, sagging of the binder, wrinkling of very flexible webs, and shifting of abrasive grains. Furthermore, festoon curing areas require large amounts of space and enormous amounts of energy.  Radiation curing processes have been used in an attempt to avoid the disadvantages of festoon ovens.  This invention provides abrasive products comprising abrasive grains bonded together or bonded to a backing by means of a binder comprising an oligomeric aminoplast resin having on average at least one pendant .alpha.,.beta.-unsaturated carbonyl group per oligomeric unit.  The oligomeric aminoplast resins polymerize via free radical polymerization at the site of the .alpha.,.beta.-unsaturation.  Polymerization is initiated by a source of free radicals.  The source of free radicals can be generated by electron beam radiation or by an appropriate curing agent or initiator upon exposure to heat or radiation energy.  The coated abrasive of this invention demonstrates improved grinding performance under severe conditions as compared with coated abrasives comprising radiation curable resins heretofore known.
