Title: Process for the production of a metal soap layer as an antifriction layer on a metallized registration support
Inventor: BRISKA MARIAN DIPL ING
IPC: D21H19/16
Filed: 1983-01-21
Granted: 1987-08-06
Abstract: A sufficiently thick gliding layer is produced on the recording surface of a record carrier of the type comprising an aluminum layer applied over a lacquer layer coated on a support layer. The back surface of the support layer is also coated with a lacquer layer. A fatty acid or a mixture of fatty acids is admixed with one of the two lacquer layers and a metal-diketone or a metal-keto-ester is admixed with the other lacquer layer in approximately in a stoichiometric ratio to the fatty acid. Following the coating of the material with aluminum in a vacuum, the record carrier material is wound into a roll, and stored.

Title: Apparatus for supporting and positioning the human anatomy and method of adjusting this apparatus
Inventor: SWAIN STEPHEN C
IPC: A47C7/46
Filed: 1983-10-24
Granted: 1988-09-08
Abstract: A plurality of support modules (14), is secured to a chassis (12). Each support module has at least one anatomy conforming support element for contact with a portion of the human anatomy and a deformable member or segment that positions the anatomy conforming support element with respect to both the human anatomy and the chassis. In one embodiment, the support module is first formed from a generally planar sheet member having at least two supporting elements separated by a relatively deformable portion of the planar sheet member. Thereafter, the sheet member is bent into a preform to conform to the general shape of the human anatomy. At least a part of this bending occurs about a predetermined axis (or axes) that lies (or lie) in the relatively deformable portion (or portions) of the sheet member. Further bending of the preform along each predetermined bending axis can be employed to custom fit the preformed support module to the specific anatomy of the individual. Such bending takes place about the predetermined bending axis because the relatively deformable portion of the sheet member deforms before the supporting element(s) even though the bending force is applied in a non-normal, but not parallel direction to the bending axis. The axis of bending is related to the human anatomy and to the chassis. Preferably, in the case of plural bending axes, the relative degree of bendability of the deformable portions is controlled to achieve bending about each axis without affecting the previously bent portions of the support module.

Title: The manufacture of crosslinked copolymer beads, the copolymer beads themselves and their use as adsorbents or, on incorporation or addition of functional groups, as ion exchange resins
Inventor: BARRETT JAMES HENRY
IPC: B01J39/20
Filed: 1983-06-27
Granted: 1989-12-21
Abstract: Polymer beads are produced by forming an agitated suspension of lightly crosslinked seed particles, at least substantially free of protective colloid, swelling these by addition of monomer under polymerization conditions while balancing suspension conditions, feed rate, agitation and polymerization rate to avoid, discourage or minimise particle agglomeration, continuing polymerisation after monomer feed is completed and separating the resulting beads. The monomers in the seed particles and monomer feed comprise styrenic and/or aliphatic ethylenically unsaturated units and a suitable light degree of crosslinking of the seed particles is 0.1 to 5%. The beads when macroreticular are useful as adsorbents and when containing ion exchange functional groups, are useful, whether gel or macroreticular, as ion exchange resins. Preferred beads exhibit multi-stage swelling in a swelling solvent and have a birefringence pattern under polarised light characteristic of high bead stress.

Title: Stepping motor assembly
Inventor: BESSON RENE
IPC: H02P8/02
Filed: 1985-05-02
Granted: 1988-03-17
Abstract: The purpose of the invention is the realization of a motor assembly formed from a stepping motor and its control circuit capable of operating at a maximum speed substantially greater than that obtainable with comparable existing assemblies. This is effected by substituting for the single coil or for each coil of a known motor two or more windings and adopting a control circuit which connects the windings in series or parallel according to whether motor drive pulses of low or high frequency are applied thereto. The total number of winding turns and the sum of the resistances of the windings are preferably chosen to be equal respectively to the number of turns and the resistance of the coil which they replace in order to avoid basic modification of the characteristics and performances of the motor when operating at low speed. When the windings are connected in parallel their resistance and equivalent self-inductance are less than that of a single coil. The energy transfer from the voltage source to the rotor of the motor is increased and facilitated and the maximum speed of the motor is considerably increased.

The apparatus includes a waveform generator that generates a periodic signal, an antenna probe that transmits the signal into the test sample and receives from the test sample a corresponding periodic signal, the waveform of which has been distorted or otherwise transformed by the chemical, and a detector circuit that quantifies the transformation of the signal to determine the concentration of the chemical in the test sample. The waveform shape and frequency are selected so that the transformation is particularly responsive to the presence of a selected chemical substance, so that the magnitude of the distortion or transformation of the signal is directly related to the concentration of the selected chemical substance.
