Title: Plant watering/feeding assemblies
Inventor: STALEY BRIAN ARTHUR
IPC: A01G27/02
Filed: 1988-06-09
Abstract: A self watering plant pot has an inner container (1) for the plant (3) and its growing medium. The container (1) floats in buoyancy liquid (27) in a further container (4). A valve diaphragm (18) is connected to both containers (1, 4) at their bottom walls (17, 9) to lead water (6) for the plant from an outer, reservoir container (5) through the buoyancy container (27) and into the inner container.

Patent GB-2228388-A (GB)
Title: Combining video signals
Inventor: ARBEITER MICHAEL
IPC: H04N17/00
Filed: 1990-01-10
Abstract: In a video mixing device control signals defining at least the boundary between the parts of two input images A and B which are to appear in a composite output image C are stored in a memory 7 in respective memory locations corresponding to image elements of the output image at which said boundary is to appear. Control signals within and without the boundary may have the same or different values (Fig 2). Each memory location may be simple or multi-bit, and there may be more locations than pixels so that a stored boundary may be moved over the image area by appropriate addressing. To alter the boundary while processing, signals are read from memory 7 to a buffer alternately with writing new data into the memory. To produce a more satisfactory circular boundary, two circles of the same radius, displaced vertically by one line, are written into the memory.

Title: Feeding boards from a stack.
Inventor: PARK MARCUS GERARD
IPC: B65H3/02
Filed: 1990-01-11
Abstract: Apparatus for feeding boards in a single direction sequentially from the bottom (or top) of a stack through a feed gate, comprising three parallel rows of frictional contact conveying wheels (24) each row driven by a separate electric motor (21, 22, 23). The boards (12) are fed sequentially onto an output conveyor (1) without nip rolls. An electronic control system (27) accelerates the three rows of wheels (24) simultaneously to line speed and progressively decelerates each row of wheels when the trailing edge of each board has advanced and before the next succeeding board has descended. The conveying wheels (24) project through apertures in a suction box (16) which holds the boards in contact with the conveying wheels during conveyance. The boards are fed without crush accurately and in perfect register without slipping and with minimum power requirements.

Title: A crown-shaped cage for a radial bearing
Inventor: UENO HIROSHI
IPC: F16C33/41
Filed: 1990-04-27
Abstract: Pockets (11) for receiving balls (15) have their entrances (14) axially on one side of a cage and are spaced from each other at regular intervals in a circumferential direction by partition walls (12). Each wall has engagement portions (12a) in an inside part thereof and at opposing sides thereof towards respective pockets, which portions serve to engage and stop the ball in radial and axial directions. In each wall a relief space (13) is provided to allow deflection of the wall when a ball is inserted into the pocket. The presence of the relief spaces (13) and the engagement portions (12a) means that the cage can be made of a plastics material, such as PPS or PEEK, which offers excellent heat resistance but low flexibility. <IMAGE>

Title: Apparatus for perforating e.g. a breathing hose
Inventor: CORCES RONALD JAMES
IPC: A62B9/00
Filed: 1991-04-08
Abstract: Apparatus 10 for perforating a resilient membrane such as a breathing hose (12) includes a blade 62, explosively actuated means 78 for impelling the blade 62 into the resilient member 12 and means responsive to the occurrence of a predetermined event for firing the means 78. In the case of a breathing hose attached to a mask (14, Fig. 1), the predetermined event is the emergence of the apparatus from water leaving the hose partially filled with water, the cartridge 78 being fired by an emergence-from-water-activated sensor circuit 80 to perforate the hose above the water level to enable the wearer to breathe ambient air. In an alternative sensor circuit, Fig 6, operated by battery (140), in which current flows through water between electrodes (110 & 112), capacitors (150, 170) begin to discharge, when the electrodes emerge from the water, operating a load (120) e.g. an electro-explosive device within between  &cirf& 2 and  &cirf& 3 seconds. The blade 62 may cut against an anvil 108. <IMAGE>

Title: Method of forming single-crystal semiconductor films
Inventor: SUGAHARA KAZUYUKI
IPC: H01L21/20
Filed: 1992-05-06
Abstract: A non-single-crystal semiconductor film connected to a single-crystal semiconductor substrate 1 via a seed hole 3 in an insulator layer 2; is irradiated by a beam compounded of a first energy beam 61 having a power density capable of melting the non-single-crystal semiconductor film and a second energy beam 62 having a power density not capable of melting the non-single- crystal semiconductor film but capable of softening the insulator layer below it. The non-single-crystal semiconductor film is thus melted and resolidified by scanning its surface with the compound beam, starting from the seed hole, in such a manner that the first energy beam is irradiated first and the second energy beam is irradiated second, to transform the non-single-crystal semiconductor film into a single-crystal semiconductor film. <IMAGE>

Title: Scaffold plank retainer
Inventor: MCCARTHY JOHN JAMES
IPC: E04G7/28
Filed: 1993-01-05
Abstract: A clamping device primarily for use in the scaffolding industry, which is shown in situ in figure 4. The device is for clamping scaffold planks or boards to the various parts of a scaffolding arrangement in order to prevent the boards from being blown off by winds, to reduce theft, and to prevent personnel treading and falling from loose boards and subsequent overhangs. The device comprises a standard tube clamp 3 and a side arm 1, 7 which clamps over the edge of a plank 9. Trip hazards on current fixing methods are considerable and highly dangerous to scaffold users.
