Abstract: Process for treating hydrophobic polymer surfaces to form hydroxyl moieties thereon comprises ozonating the surface of said hydrophobic polymer to form hydroperoxy groups thereon, and then irradiating said ozonated surface with ultraviolet light or exposing to heat to convert the hydroperoxy groups to hydroxyl moieties in the presence of a hydrogen donor. Such hydroxylated surfaces possess hydrophilic properties and can undergo the chemical reactions characteristic for hydroxyl groups. Polymers so modified are useful in biomedical devices, semipermeable membranes, films, fibers and especially contact lenses.
Patent NO-165781-C (NO)
Inventor: DAHLMAN KARL
IPC: A01D34/63
Filed: 1990-06-13
Abstract: The present invention comprises a lawn-mower having a grass-collector (6). For attachment of the collector (6) on the lawn-mower the casing (1) of the mower is provided with a curved superstructure (7). The front edge (13) of the grass-collector (6) like the superstructure (7) has the same curvature as the outer turning radius of the knife (5). In mowing, the mown grass is sucked towards the casing (1) and thrown back through a passage (11) directly into the collector (6). Due to the curvature of the superstructure (7) and the collector (6), respectively, it is possible to connect the grass-collector (6) as far as to the knife system, which eliminates any transportation distance for the mown grass which often is both wet and sticky.

Title: Hydraulic positioning system for a hydraulic turbine governor
Inventor: GABELLINI RICHARD A
IPC: F03D11/00
Filed: 1990-10-03
Granted: 1994-11-22
Abstract: HYDRAULIC POSITIONING SYSTEM FOR A     HYDRAULIC TURBINE GOVERNOR                            ABSTRACT The hydraulic piston cylinder assembly which operates the governor of a turbine which powers a hydropower generator has a servo valve capable of flowing only a portion of its flow requirements during normal low power fluctuation conditions of the turbine's operation. During high power fluctuation conditions of the turbine's operation, such as during start-up, hydraulic fluid also flows to and from the piston and cylinder assemblies through high flow pressure and return conduits that bypass the servo valve.  Control of fluid flow in the high flow conduits is accomplished by a proportional throttling valve located in the high flow return line. The servo valve and proportional throttling valve together have a flow capacity which is equal to the flow requirements of the piston and cylinder assembly and they are both actuated by the same electronic controller. However, the electronic controller only actuates the proportional throttling valve when the flow requirement of the piston and cylinder assembly exceeds the flow capacity of the servo valve.  A hydraulic logic circuit activated by the electronic controller allows the high flow pressure and return conduits to be reversed for two-way operation of the piston and cylinder assembly.

Title: Method and system for encoding and decoding frequency shift keying signals
Inventor: SCHOENEBERG RAINALD
IPC: H04L27/24
Filed: 1991-08-28
Granted: 1996-07-09
Abstract: A system and method for encoding and decoding a frequency-shift keyed data signal for transmission over a non-ideal communications channel that utilizes phase-coherently  combined  halfwave   segments   of sinewaves  with  a  finite  number  of  different frequencies and equal amplitudes.  A stream of data characters is encoded into a transmit sequence {S(n)} of positive numbers which defines an ac signal of halfwave segments of sinewaves of fixed, preselected amplitude.  The ac signal encoding the stream of data characters  is  transmitted  over the communications channel and received as a perturbed ac signal.  The received  signal  is  identified  by  consecutively determining the time durations between peak values or between zero crossings of each segment yielding a receive sequence {E(n)} of positive numbers.  All or parts of this receive sequence are then compared with each of a set of preselected, stored sequences, each representing  a  stream of  none,  one  or more data characters.   The actual stream of data characters transmitted is selected as the stream producing the smallest  errors,  within  a  preselected  bound,  in comparing the stored stream-representing sequences to all or parts of the receive sequence.

Title: Process for coloring an electrostatic image
Inventor: HAYS DAN A
IPC: G03G15/08
Filed: 1991-09-24
Granted: 1999-05-11
Abstract: Selective coloring of bi-level latent electrostatic images is obtained through a combination of 1) a scavengeless development nip enabled by an AC biased wire in self-spaced contact with a toned donor roll, 2) a belt image receiver such as either a photoreceptor or electroreceptor without a [substrate and; ground plane and 3) an array of addressable, stationary electrodes positioned behind the belt in alignment with the AC biased wire. Selective coloring of the electrostatic image is obtained by selectively DC biasing addressable, stationary electrode structures forming electrode arrays positioned behind the belt. By controlling the level and timing for applying a DC bias to each electrode segment, the developability can be switched on and off with x,y addressability in the plane of the electrostatic image. Thus, with a system having resident multi-colored development systems, different areas of the electrostatic image can be developed in a single pass with different colors and perfect registration simply by controlling the DC'electrical signals to the electrodes.

Title: Switching regulator
Inventor: OZAWA KENICHI
IPC: H02M3/28
Filed: 1992-03-23
Granted: 1996-05-14
Abstract: In  a switching regulator, input  voltage  is applied  to a primary coil of a transformer  through  a location  between  a  collector and  an emitter  of  a switching transistor connected in series to the primary coil  of the transformer.  A pair of  output  terminals are  connected to a secondary coil of  the  transformer through  a rectifier smoothing circuit.   A  comparator compares  output voltage occurring between  the  output terminals with reference voltage to generate an  output signal.   On the basis of the output signal, a  control circuit applies a drive control signal to a base of the switching  transistor.  The reference voltage is  given such   that  first  voltage  maintained  substantially constant  and  second  voltage such  as  outside  input voltage or the like capable of being regulated over  a relatively large varying width are added to each other.

Title: Mode converter
Inventor: VAN DER TOL JOHANNES JACOBUS G
IPC: G02B6/126
Filed: 1992-05-12
Granted: 1997-08-26
Abstract: Mode converter for converting a fraction of one guided mode of an optical signal in an incoming optical waveguide section (A) into another guided mode in an outgoing wave-guiding section (C) by means of a periodic coupling between both guided modes in an intermediate optical waveguide section (B). The intermediate section (B) has a periodic geometrical structure as a result ofan N-fold periodic sequence of two light-guiding subsections (P,Q) within a period length (LP + LQ). The sequence can be obtained by arranging for the waveguide profiles of the subsections to differ from one another, preferably as a result of differences in width. The sequence can also be obtained by offset joining of the two subsections with the same waveguide profiles. Advantages are:the high degree of integrability, the ability to co-integrate a laser light source ID an optical section of a coherent optical receiver and the achievement of a new integrated design of such an optical section, which design is free of metallizedelements.
