Patent GB-2132657-A (GB)
Title: A screen device for a drainage system
Inventor: COPE RONALD WILLIAM
IPC: E04D13/08
Filed: 1983-10-31
Abstract: The device is adapted to be incorporated in a domestic rain water drainage system and incorporates a screen 7 through which water can flow to a discharge outlet but which traps foreign matter such as leaves. The screen is inclined at an angle to the horizontal so that the foreign matter travels down the inclination to be discharged from the device. By this means, the foreign matter does not remain on the screen obstructing the through flow of water. <IMAGE>

Title: An input device and a method of inputting data to a computer system
Inventor: PROSENKO GARY JOHN
IPC: G06F3/033
Filed: 1984-04-06
Abstract: An input device for a computer system comprises a touch sensitive surface or pad 21 for providing signals representative of the position of a user's finger. Movement of a cursor on a display screen of a computer system is controlled in response to a user's finger moving over a defined cursor control area 63 of the surface, e.g. so that it is displaced by an amount related to the displacement of the finger and to finger speed. Once the cursor has been correctly positioned a short tap on the area 63 generates an execution signal to instruct the computer to carry out the instructions determined by the prior cursor movement. The touch-sensitive surface also has a plurality of discrete areas 65,67,69,71,73,75,77,79 adjacent the cursor control area which act as two position switches and generate control signals of the type for which discrete push button switches are generally employed. <IMAGE>

Title: Method for removing dissolved oxygen from aqueous media
Inventor: DESILVA SUNIL GREGORY
IPC: C23F11/18
Filed: 1984-10-19
Abstract: Water for use in steam generation systems, which is contained in a storage tank, is deoxygenated for use in the system by adding hydrogen to a stream of the water and intimately mixing the same, pressurizing the stream to a pressure of 60-150 psig, and contacting the pressurized stream with a catalyst bed of palladium or platinum dispersed on a solid carrier. The hydrogen reacts with the dissolved oxygen in the presence of the catalyst at ambient temperatures, to produce a deoxygenated stream of water containing less than 10 ppb of oxygen. The deoxygenated water can be returned to the storage tank or supplied directly to the steam generation system.

Abstract: In apparatus for producing a large number of identical, independent (small-volume) streams of liquid, a gear pump comprises a housing 1 provided with toothing 6 engaged by at least one pinion 8 guided by a rotor 9. A supply of fluid (12, Fig. 2) leads to an annular passage 14 in the interior of the rotor and thence to the toothing, whereas fluid is discharged through outlets 15 which proceed from the toothing. Back-flow is prevented by valves 20, which may instead comprise slide valves. The rotor has a circular-cylindrical outer surface 21 which is adapted to the interior of the pump housing 1 defined by the addendum circle 5 of the toothing 6 and has at least one circular-cylindrical pocket 7 for accommodating a pinion 8 meshing with the toothing 6.

Patent GB-2155119-A (GB)
Title: A lubricant slinger dynamoelelectric machines
Inventor: UHEN RICHARD FREDERICK
IPC: H02K5/16
Filed: 1985-02-19
Abstract: A lubricant slinger mechanism for preventing the loss of oil or other lubricant which is pumped between the rotor shaft and bearing in an electric motor or other dynamoelectric machine. The slinger is mounted to the rotor shaft and mounted adjacent the end of the bearing out of which oil flows as it is pumped along the shaft from the reservoir. The slinger initially throws the oil radially outward against an inner oil well cover, and the provision of an impeller, such as a spiral vane on the outer peripheral surface of the slinger, imparts an axial component of velocity to the lubricant which impels it rearwardly toward the reservoir and prevents the migration of oil out of the forward end of the oil cover through which the rotor shaft extends. The slinger, in one form, includes an annular cup portion which overhangs the end of the bearing so that lubricant is thrown off the slinger at a point rearwardly of the end of the bearing. The slinger is preferably formed with an opening that is larger in diameter than the shaft and includes a tapered surface on one end so that as the brass rotor sleeve is inserted into it, it centers the slinger and enables the brass sleeve to be pressed therein by means of automatic assembly machinery.

Title: Loudspeaker system
Inventor: VILLA FRANK
IPC: H04R1/34
Filed: 1985-12-12
Abstract: A loudspeaker with omnidirectional radiation properties has a vertical enclosure (1) extending from a support, an electro-acoustic transducer having a diaphragm (2) closing an opening in one end of the enclosure distal from the support and a baffle (3) mounted beyond said one end opposite an outer surface of the diaphragm so as to define a continuous peripheral opening between the baffle and the enclosure which is less than one quarter of the shortest wavelength to be radiated. Preferably the baffle is profiled so that the distance between the diaphragm and the baffle is nowhere greater than one quarter of the shortest wavelength to be radiated, thus suppressing unwanted resonances in the opening. A second baffle can be mounted opposite a bass reflex opening (26) in the other end of the enclosure so as to define a second continuous peripheral opening. The transducer may be a low range unit, with a third baffle (15) mounted beyond baffle (3) to provide a third peripheral opening (24) from high range transducers (16) mounted opposite each other on the first (3) and third (15) baffles. <IMAGE>

Title: Check valve
Inventor: CRAWFORD RICHARD A
IPC: F16K15/02
Filed: 1986-03-26
Abstract: A unitized check valve for use with corrosive fluid includes a generally cylindrical body (10). A valve seat (24) is disposed in the body around an aperture therethrough and a first set of angularly spaced apart arcuate flanges (46) depends from the outlet end. A valve disk (12) is coaxially associated with the seat and is adapted for axial movement to block and unblock the aperture in order to control the flow of fluid through the body. A valve retainer (16) has a second set of angularly spaced apart arcuate flanges (70). The flanges (70) of one of the sets extend generally radially inwardly and the flanges (46) of the other one of the sets extend generally radially outwardly. The flanges (70) of the second set are positionable between adjacent ones of the flanges (46) of the first set. A coil spring (14) bears against the valve disk (12) and the retainer and is responsive to flow fluctuations on the disk for thereby permitting movement of the disk. Alignment of the flanges (70) of the second set between the flanges (46) of the first set and rotation of the retainer (16) causes the flanges (70) of the second set to be engaged with the flanges (46) of the first set for thereby preventing axial displacement of the retainer so as to maintain the valve in assembled condition. <IMAGE>

Patent GB-2192501-A (GB)
Title: Electrostatic precipitators
Inventor: RUSSELL-JONES ANTHONY
IPC: B03C3/68
Filed: 1986-07-11
Abstract: In a method of operating an electrostatic precipitator 10 in a reduced voltage, power saving mode, the electrode voltage is periodically increased to induce energetic flashover, the flashover is continued for a period of time sufficient to dislodge dust accumulations on the electrodes, and then the voltage is reduced so that the precipitator operates again in the power saving mode. The precipitator power source 11 has a control unit 12 responsive to a feedback signal 13 indicative of precipitator voltage or flashover rate and to an opacity signal 14. The source 11 operates in the power saving mode when the opacity signal 14 indicates that full power is not required to achieve satisfactory precipitation. The frequency and duration of the periodic voltage increaser may be preprogrammed on the basis of previous experience. <IMAGE>
