Inventor: CHURA WILLIAM D
IPC: B05B7/24
Filed: 1996-05-23
Abstract: A double barrel sprayer (2) for applying a diluted product such as a diluted cleaning solution to a surface for cleaning thereof and rinsing the diluted product from the surface by spraying a water-only rinse onto the surface. The sprayer (2) can include a force fitted orifice plate (50) with one or more holes (52a and 52b) for adjusting the water/product mixing ratio or an insert having passages therein for providing a desired product dilution ratio. To provide different spray patterns for the water-rinse or diluted product, the sprayer (2) can include a shroud having suitably shaped exit holes. The sprayer (2) includes separate flow paths for water-only rinse (23) and the diluted product (24). The flow path for the diluted product (24) includes a mixing chamber (28) in which concentrated product is siphoned from a container (6) and mixed with water supplied by a garden hose (4). Prior to mixing with the water, the concentrated product passes through the orifice plate (50) or insert to provide a substantially constant water/product ratio over a wide range of water pressures. The sprayer (2) includes a removable cover (30) which includes a pair of outlets suitably sized and shaped to obtain desirable spray patterns for water-only rinse and the diluted product sprayed from the sprayer (2). A rotatable valve (40) allows selective application of water or diluted product.

Title: Analog-to-digital transition: selecting the optimal cellular radio mix
Inventor: BENVENISTE MATHILDE
IPC: H04W16/06
Filed: 1998-04-08
Abstract: In a transition phase of a cellular cell from analog-to-digital radio service it must be determined how many of the base station radios in a cell must be changed over from analog to digital, given the proportion of mobile phones with dual-mode capability to analog phones. A dual-mode mobile phone has the capability to interface with both analog and digital radios. In determining the radio mix, it is desirable to maximize the call handling capacity of a cell, or minimize the blocking experienced by the mobile subscribers. To address these questions, an analytical model is developed to compute the blocking rate experienced by mobilecallers in a cell, given the cell's offered load, the mix of analog and dual-mode mobiles, and the analog-digital split of the RF channels available to the cell. The model's results enable selection of the channel split that gives the lowest blocking rate, and to compile charts that show the relationship between the proportion ofdual-mode mobiles, the number of digital radios in a cell, and the maximum offered load that can be served at a specified blocking rate.

IPC: A61B17/20
Filed: 1997-01-08
Abstract: This invention is a system for making multi-site skin tests primarily for use by allergists making use of a multi-head applicator (5), and a matching multi-well dip well tray (20). The applicator (5) has an elongated handle (6) with arms (8) extending transversely from opposite sides having downwardly extending legs (7) terminating in multi-pointed ends or heads (12) capable of picking up and retaining small quantities of liquid skin testing substances. The multi-pointed ends or heads (12) occupy the same plane and are arrayed in a pattern suited for simultaneously making multi-site skin tests. The applicator (5) cooperates with a multi-well dip well tray (20) with a plurality of dip wells (22) arrayed in patterns which match the pattern in which the multi-pointed ends or heads (12) on the cooperating applicator (5) are arrayed. The individual dip wells (22) have a capacity to hold quantities of skin testing substances or medicaments equaling many times the volume of a single dose or increment that is picked up by one of the multi-pointed ends or heads (12) on an applicator (5). Both the applicator (5) and dip well tray (20) have guidance formations thereon whereby the user can readily orient the multi-point pickup ends or heads (12) on the applicator (5) with the dip wells (22) so that the heads can be readily and accurately lowered into the matching dip welts (22) without damaging the points (12) of the applicator (5).

Patent CA-2247033-A1 (CA)
Title: Liquid containment and dispensing device with improved position indicating indicia
Inventor: WALLACE J KENNETH
IPC: B41J2/175
Filed: 1998-09-14
Abstract: An ink containment and dispensing device for an ink-jet printer is provided with a main reservoir in the form of a flexible pouch, which is typically maintained at ambient pressure. The main reservoir is coupled to a variable volume chamber via a one-way valve which allows the flow of ink from the reservoir to the chamber and prevents the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet, which is normally closed to prevent the outward flow of ink.  However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer. The chamber is part of a pump provided with the ink supply that can be actuated to supply ink from the reservoir to the printer. The pump has a linearly acting pumping member and a flexible diaphragm that overlies the pumping member, the diaphragm being impervious to the transmission of oxygen and moisture therethrough to prevent degradation of the ink within the chamber. The flexible pouch is contained within a rigid, outer shell having an opposed pair of shorter sides interspersed with an opposed pair of longer sides, and the shorter sides of the shell, in the region of the closed end of a cup-shaped shell, are configured for grasping and for identifying the location of the closed end of the shell.

Title: Hip joint socket with a special thread
Inventor: H RMANSD RFER GERD
IPC: A61F2/34
Filed: 1997-04-21
Abstract: The invention concerns a screw-in type artificial hip joint socket with a special thread for implantation in human beings. Hip joint sockets of this type usually have a flat thread with parallel teeth flanks or a triangular thread with a neutral teeth position, the axial pitch being conventionally constant. However, such embodiments are unfavourable because they do not take sufficiently into account the forces which arise during implantation as well as during the intended use, or they cause an unnecessarily extensive bone bad destruction during an eventually required explantation. With the invention a purposefully optimization of the hip joint socket thread is provided, wherein the thread profile, the angular orientation of the thread teeth and a non-linear thread pitch is utilized, in order to ensure an effortless screwing, a stable seat in the long term and an unproblematic explantation.

Title: Speech reception via a packet transmission facility
Inventor: CHEUNG CUTHBERT
IPC: H04L29/06
Filed: 1998-12-01
Abstract: Degradations in packetized voice communications received by a non-synchronized entity, via a packet network, are reduced by adjusting a depth of storage in a jitter buffer of the receiving entity. Units of voice samples data are stored in the jitter buffer as they are received. Stored units are normally extracted and delivered to a processor one at a time at a regular rate for the generation of audible speech. From time to time the rate of extraction can be accelerated by extracting two units while delivering only one. Also the rate of extraction can be retarded by not extracting a unit while delivering a substitute unit in place of the unit that would normally have been extracted. The depth of storage is thereby controllable in response to packet reception events such that delay is minimized while yet providing sufficient delay to smooth variances between reception events.

Title: Permanent magnet type electrical rotating machine
Inventor: TAKAHASHI NORIO
IPC: H02K1/16
Filed: 1999-01-21
Abstract: The present invention makes the slots of stator core 2A of stator 1A rectangular enclosed slots 4A in which triangular projecting parts 3a are formed on the inner periphery side of this stator core 2A. It cools stator core 2A by passing cooling gas through projecting parts 3a. It also causes the magnetic flux that reaches stator core 2A  from permanent magnets 6 by passing through retaining ring 8 and air gap 9 to pass the inner periphery sides of projecting parts 3a of stator core 2A. By this means, it prevents oscillation of magnetic flux density in the peripheral direction, reduces the eddy currents in retaining ring 8 which accompany this oscillation, and prevents temperature rise.
