Patent CH-518124-A (CH)
Title: Aq emulsions for photography
Inventor: JAN FRANS VAN BESAUW
IPC: B01J13/12
Filed: 1969-11-19
Abstract: Microcapsules containing water and dissolved compounds (first aqueous phase) in a solid cover of a polymer material are formed by (a) emulsifying the aqueous material or hydrophibic component in a soln. of a polymer, the solvent for the polymer being immiscible with water, and having a b.p. below 100 degrees C, (b) emulsifying the formed emulsion in an aqueous soln. of a hydrophilic colloid (second aqueous phase), and (c) removing the solvent for the polymer from the system by evaporation, as in BE.634,668. The improvement comprises preventing the transfer of a dissolved compound from the first aqueous phase to the second aqueous phase by dissolving the compound in the second aqueous phase at the same or a higher concentration than present in the first aqueous phase. - The microcapsules are suitable for encapsulating materials such as catalysts for chemical reactions, develops for use in silver halide photography, pH-controlling compounds, leuco dyes, diazonium compounds, or couplers for diazonium compounds. The present modified process prevents the transfer of dissolved compounds from the first aqueous phase to the second aqueous phase. In this manner, the concentrations of dissolved compounds in the first aqueous phase is held constant, so that the aqueous soln. which is encapsulated has a definite concentration.

Title: A mobile phone gain control method using bit error rate, and a dynamic channel allocation method
Inventor: PECEN MARK EDWARD
IPC: H03G5/16
Filed: 2000-01-12
Abstract: A mobile phone AGC controller monitors the received signal power and the receiver bit error rate. When the received signal quality is lower than optimal, the AGC controller tracks the value of the BCCH carrier. As the mobile phone approaches the base station, the received signal quality and the carrier level become sufficient to permit transmitter power reduction at the base station, thus minimizing interference and maximizing cell occupancy. Additional gain reduction may be applied in the receiver when the mobile phone is close to the base station. In particular, if the ratio of the carrier signal power to the bit error rate exceeds an optimum level, then the receiver gain may be reduced. Channels may be allocated dynamically so that mobile phones having a common distance from the base station are on a common channel (figure 11).

Title: USB-based networking and I/O hub
Inventor: BEALKOWSKI RICHARD
IPC: G06F13/38
Filed: 2000-03-27
Abstract: Network communications between personal computer systems using Universal serial bus (USB) communications is provided by a USB hub 200 which allows multiple hosts to exist in the same USB-based network. The networking hub includes a number of sub-hubs 202, 204, 206, each connected to an upstream computer system and having ports 230, 232, 234, for peripheral devices. The sub-hubs are connected to one or more virtual network adapters (VNA) 210, 212, 214 which emulate a network adapter and allow communication between the multiple hosts. When a host queries its sub-hub over its upstream connection 220, 222, 224, the sub-hub indicates the VNA as an attached USB function. The host then attaches the VNA as a USB/Network function since it sees the VNA as a network adapter attached to the USB sub-hub.

Title: Lightweight handle
Inventor: HARDIGG JAMES S
IPC: B65D25/28
Filed: 1999-01-06
Abstract: The handle assembly comprises a stationary bracket (12) which mounts to a container wall (14) and a movable handle (16) pivotally connected to the bracket (12).

Title: Large aperture float valve assembly allowing rapid downhole movement of a tubular
Inventor: BAUGH JOHN L
IPC: E21B21/10
Filed: 2001-06-18
Abstract: An arrangement allowing rapid descent of a tubular 24 though borehole fluids comprises one or more selectively closable valves 52, 56 and an associated actuator, with a flowpath (arrowed) though the actuator providing a minimum flow area though the tubular. This flowpath area exceeds 24 cm<SP>2</SP> and is preferably about 60 cm<SP>2</SP>. The actuator may include a moveable element, such as a floating sleeve 84, that is displaced by fluid pressure as the tubular descends, opening at least one passageway 92 though the actuator. The valve may be biased towards its closed position but locked open by a collet 74 and ring 76. The movable component may free the valve from this restraint, enabling closure. The floating sleeve may support a cone 86 to direct trigger objects such as drop balls (100, figure 4c) to a seat (104, figure 4c) that controls valve closure. A second floating sleeve (34, figure 1c) may be mounted on a wiper plug (46, figure 1c), relative movement exposing fluid ports (42, figure 1c) in the plug.

Title: Banding reduction in incremental printing by using selective sets of active and inactive nozzles at either end of the printhead array
Inventor: KROUSS PAUL R
IPC: B41J11/42
Filed: 2002-04-30
Abstract: A method of printing with a printer of the type comprising a linear arrangement of parallel pens 38-48 mounted on a scan axis, each pen comprising an array of ink ejection elements, comprises printing a series of swaths, each from a different pen, on a printing medium between successive incremental advances of the medium in a printing advance direction (PAD) relative to the pens wherein the swaths are printed such that the boundaries of at least two of the swaths are offset from one another in the PAD. The nozzles of the various pens may be divided into active 110 and inactive 100 sets of nozzles, such that only the active nozzles are used to print the swaths and so that the different active nozzle sets each have offset endpoints in the PAD to print offset swath boundaries. Control circuitry may be used to cause at least two of the pens to print from different sets of corresponding ink ejection elements. The printer may simultaneously print first and second swaths of an image where the first swath is of reduced width relative to the first pen length and the first and second swath boundaries are offset to each other.

Title: A class F Doherty amplifier using PHEMTs
Inventor: KHAN RASIB
IPC: H03F1/02
Filed: 2002-09-06
Abstract: A Doherty amplifier uses a GaAs pseudomorphic HEMT as output transistor of the peaking amplifier 120. The PHEMT absorbs substantially no power from the common node 135 when the peaking amplifier is inactive. A silicon LDMOS transistor would absorb much more power, reducing amplifier efficiency. The output networks 118 and 128 cause the amplifiers 110 and 120 to operate in class F or in modified class F by providing short circuits at the lower even harmonics and open circuits at the lower odd harmonics. Each network (figure 4B) comprises a low-pass ladder filter and a shunt resonator with resonant frequency close to the fundamental frequency. GaN or SiC devices may be used instead of a PHEMT. The amplifiers may have multiple stages (figure 2). The operating frequency is around 2.14 GHz.

Title: Extended focal region measuring apparatus and method
Inventor: DALY DANIEL JOHN
IPC: A61B5/00
Filed: 2003-12-12
Abstract: A method and apparatus for measuring an apparent depth (1) of a section of an animal body are disclosed. Light is focused concurrently to an extended focal region (R) comprising a plurality or continuum of measurement locations. Light reflected by a refractive index interface coincident with one of the plurality of measurement locations is then detected. Detected light signals are generated from light reflected from first and second interfaces respectively defining the section under investigation, so that the apparent positions of the first and second interfaces may be derived. A confocal arrangement and an axicon element (12) may be employed. Preferably, the section is the aqueous humor (34) of an eye (30). From changes in its refractive index (n) corresponding changes in glucose concentration in the aqueous humor and, in turn, in the bloodstream of a patient may be derived, offering a non-invasive monitoring means for diabetic patients. Other compounds and structures of the body may alternatively be investigated.
