Title: Automatic spraygun
Inventor: PETTIT NEVILLE THOMAS
IPC: B05B7/00
Filed: 1990-12-06
Abstract: An automatic spraygun operable by high volume low pressure air comprises a spraygun body (1) which includes a threaded inlet (2) receiving air from a compressor or airline and supplies high volume low pressure air to annular chambers (3 and 4) and to a nozzle (5) which is screwed into a sleeve (7) which is sealed to a rear baffle (6) by an annular seal (8). A control ring (11) is positioned between the baffle (6) and body (1) for rotation relative to the baffle to control the flow of a fluid to be sprayed and air. The control ring (11) has a series of peripheral teeth (33) which mesh with a pinion (32) rotatably mounted in the body (1) to adjust the position of the control ring (11) relative to the baffle (6). <IMAGE>

Title: Seat suspension
Inventor: VAN DUSER HAROLD J
IPC: B60N2/54
Filed: 1990-12-27
Abstract: A seat suspension is provided whereby, under vibration, the seat rear portion (250, 252) pivots about the base and the seat front portion both pivots and moves vertically relative to the base. Thus vibration causes downward pivoting of the inner cushion arms (241, 243) and of the arms (258, 260) of the pivot arm assembly (256). Downward pivoting of the arms (258, 260) causes downward movement of the arms (290, 292) and with them the front cushion support bracket (280). Because the cushion is attached to the bracket (280), downward movement of the bracket (280) causes downward movement of the seat cushion along its front. <IMAGE>

Title: Switching circuits
Inventor: COTTER CHRISTOPHER JOHN HENRY
IPC: H03K17/13
Filed: 1991-01-21
Abstract: In a power control circuit for reactive loads, particularly inductive loads such as loads 0 to 5, a high power transistor (T1) is used under control of a control circuit (IC2, R9 etc) to switch the transistor on and off. The transistor, in effect, appears as a voltage controlled variable resistor in series with the load and acts either as a main switching device or as a buffer to the main switching device whereby the switching is gradual. The circuit greatly reduces the amount of noise suppression required and may, in some cases, eliminate the need for noise suppression entirely. The circuit may be controlled by a microprocessor and included in appliances such as vending machines, dishwashers and washing machines. The transistor may be a MOSFET, bipolar transistor or a triac. In the above arrangement, the transistor T1 is controlled by the added sum of a ramp generator output and a feed-back voltage and the switched voltage is applied to a threshold device via a differentiator to produce the feedback voltage. <IMAGE>

Title: A horseshoe.
Inventor: MAROUDAS DENNIS GEORGE
IPC: A01L5/00
Filed: 1991-12-19
Abstract: Conventional metal horseshoes are hard and unyielding, so that a horse wearing them can suffer damage from the transmitted shock as its feet impact the ground. Shock-absorbent plastics horseshoes are known, but under the loads involved they deform too easily, especially by spreading apart and so shearing away from the hoof. The invention proposes a novel form of shoe (10) made of a suitable plastics material and having a tension bar (20) adjustably mounted across the shoe's arms (16, 18) at the open end, each arm being cross-channelled (22) near its ends and the bar 20 carrying thereon at its ends (25) a number of formations, such as serrations or corrugations, which mate lockingly with corresponding formations in the channels 22 so as to inhibit movement of the arms to or from each other. <IMAGE>

Title: Electrochemical stabilisation of mineral masses such as concrete,and electrode arrangements therefor
Inventor: BROOMFIELD JOHN PHILIP
IPC: C04B41/61
Filed: 1992-08-26
Abstract: Mineral masses eg hardened concrete reinforced with steel rebars can be stabilised against alkali-silicate reaction and/or treated by chloride extraction or realkalisation, by passing current around an electrochemical circuit having electrodes(s) (e.g. jacketed tubular anode(s) 5, 6) and electrolyte in contact therewith located in a passageway formed in the concrete under treatment and counterelectrode(s) (eg. rebars 2), in electrochemical contact with the mineral mass and separated from the electrolyte by the mineral mass, the electrolyte containing ionic treatment material to stabilise or treat the mineral mass. The material in its ionic form is thereby made to migrate deeply into the mineral mass. The treatment material can be lithium, calcium and/or sodium ions in alkaline solution where the electrode is an anode, or nitrite where the electrode is an anode. Preferably the passageway extends deeper in the concrete than the rebars nearest the concrete surface. Electrolyte liquid can recirculate in the jacketed tubular anodes.
