Title: Paddle wheel drive for sewage treatment apparatus
Inventor: MCGILL JOHN AUGUSTINE
IPC: F03B13/00
Filed: 1985-10-01
Abstract: A rotational sewage distribution apparatus comprises a gearbox 13 rotatably mounted on a vertical shaft 12. A pair of paddle wheels 14 are rotatably mounted one on each side of the gearbox on respective horizontal shafts 15. An inlet tray 16 is located above the gearbox to receive sewage liquid from an inlet pipe and formed to direct such liquid on to the paddle wheels. An outlet tray 19 is located beneath the gearbox and extends beneath the paddle wheels to receive the liquid therefrom and direct it to a longitudinally extending distribution channel. The channel may be attached to drive means for rotation thereof, the channel being hingedly attached to the drive means with a counter-balance to allow downward movement of the channel in the vertical direction. <IMAGE>

Title: Ring detector and telephone line monitoring system for telephone answering instrument
Inventor: HANSCOM BRADFORD E
IPC: H04M1/654
Filed: 1985-11-07
Abstract: A circuit and system is provided for coupling a telephone answering instrument to a telephone line and which monitors direct current voltage levels on the telephone line to distinguish between valid ring signals and dial pulses so that the telephone answering instrument will not attempt to answer when a local telephone is being dialled for an outgoing call. The circuit and system of the invention also responds to direct current voltage differentials on the telephone line, independent of the actual direct current voltage level, to cause the telephone answering instrument to return immediately to its automatic answer position in the event the calling party hangs up, or in the event the called party picks up, during the normal announcement interval (T1), or during the message recording interval (T2). This latter feature permits the instrument immediately to return to its original condition in the presence of either of the two foregoing events, without wasting magnetic tape on blank messages. <IMAGE>

Title: Atomising disc
Inventor: CONNOLLY ANTHONY
IPC: B05B3/10
Filed: 1988-02-24
Abstract: An atomising disc, suitable for spraying a liquid agrochemical composition, has discrete delivery points 11 at its periphery, the points being of different radii from the centre of rotation 13. Spinning disc sprayers produce a spray footprint in the form of a narrow annulus. As this is moved along it produces a swath which, although covering the full width of the annulus, is greatly concentrated in two narrow bands at the edge of the swath. The present disc helps to fill in the centre of the footprint, thus producing a more even swath. <IMAGE>

Title: One-hand openable and closable umbrella
Inventor: NAGAI HISAO
IPC: A45B25/16
Filed: 1989-05-12
Abstract: A one-hand openable and closable umbrella comprising a double shaft composed of an inner shaft (1a) and an outer shaft (1b) which are smoothly slidable relative to each other. A required number of main ribs (2) are pivotally secured at each one end to a mounting member (8) on the tip of the inner shaft, and a handle (6a) and an auxiliary handle (6b) are respectively mounted at the lower end portion of the outer shaft and the lower end portion of the inner shaft (1a). The inner ends of a required number of auxiliary ribs (4) are pivotally secured to the upper end portion of the outer shaft. The outer ends of a required number of lateral auxiliary ribs (4a) pivotally support the main ribs substantially centrally thereof. The inner ends of these lateral auxiliary ribs are pivotally secured to the upper end portion of the inner shaft, and their intermediate portions are pivotally supported by the outer ends of the auxiliary ribs (4). A spring (5) provides an elastic force between the outer shaft (1b) and the inner shaft (1a) to cause the upper end portion of the outer shaft to approach the upper end of the inner shaft. An unlockable locking mechanism (7a, 9a) inhibits temporarily the relative movement of the outer shaft and the inner shaft in a first state in which the main ribs have been folded. A stopper (10) inhibits relative movement in a second state in which the elastic force of the spring (5) has been reduced. Fig. 4A shows an alternative stopper arrangement. <IMAGE>

Title: Automatic variable pitch propellor
Inventor: BELL GEORGE WILLIAM JAMES
IPC: B64C11/34
Filed: 1989-06-20
Abstract: In a propeller, for use on boats, ships or aeroplanes, the centre of thrust of each propeller blade is behind its axis of rotation in a hub. A cam or pin protruding from a collar at the base of the blade acts against a sliding ring which compresses a spring or other resilient member inside the hub whereby forces due to fluid flowing over the blades can cause a pitch change against the bias of the resilient member. The thickness of the sliding ring and the position of locking rings may be varied to change the range of pitch available. <IMAGE>

Title: Portable ramp
Inventor: BRIDGES KEVIN
IPC: B65G69/28
Filed: 1991-09-26
Abstract: A portable ramp assembly has a body 3 with an inclined channel 5 and an extension channel 11 which is hingedly mounted by spigots 12 and 13 on the extension 11 co-operating with sockets 8 and 9 in opposed side walls 7 of the body 3. The channels 5 and 11 provide a track along which a wheel e.g. of a wheel chair can roll to mount a step 30. The spigots 12 and 13 are formed at the ends of a corrugated walled shaft 41 so that the shaft 41 can be compressed axially and subsequently recover to facilitate engagement of the spigots 12 and 13 with their respective sockets 8 and 9. Relative rotation between the ramp part 1 and channel 11 permits the assembly to be adjusted for steps 30 of different height. The shaft 41 is exposed between adjacent ends 6A, 11A of the channels 5 and 11 to present a transition surface between the channels over which a wheel can roll smoothly from one channel to the other. The assembly can be folded to a condition in which the extension channel 11 is accommodated within a recess in the underside of the ramp part 1. <IMAGE>
