Title: Inflatable boats
Inventor: GORDON PETER C
IPC: B63B7/08
Filed: 1984-12-28
Abstract: The hull space (16) between the deck (15) and the lower skin (14) of an inflatable boat is in free communication with the exterior of the hull (11) but contains buoyancy bags (17) which, when inflated, lift the boat sufficiently out of the water to assist further lifting due to the boat's motion over the water, thereby enabling the boat to pick up speed more rapidly. When the boat is stationary, the buoyancy bags can be deflated to improve stability, thereby enabling divers to work from the boat more easily. <IMAGE>

Title: Semiconductor devices
Inventor: CREES DAVID EDWARD
IPC: H01L29/744
Filed: 1985-03-26
Abstract: A semiconductor device includes a heterojunction which is formed between a base region 4 of crystalline silicon, and an emitter region 1, 5 of semi-insulating polycrystalline silicon. In the case of a thyristor this gives improved operating characteristics, particularly in the case of a gate turn-off thyristor in which the dV/dt withstand characteristic is improved. Its use also improves current sharing between a number of separate emitter regions during turn-off. Emitter regions may include high resistivity fingers 5. In the case of a transistor, variation of the resistivity in a transverse direction of the emitter region by incorporation of high resistivity regions in the semi- insulating polycrystalline silicon gives improved performance. <IMAGE>

Patent GB-2171266-A (GB)
Title: PWM inverter
Inventor: CAPUTO WILLIAM ROBERT
IPC: H02M7/5387
Filed: 1986-02-12
Abstract: In a PWM inverter the maximum three-phase RMS pole-to-pole output voltage (U1, U2, U3) is increased, by generating substantially sinusoidal changing pole voltages (V1, V2, V3) having no values within predetermined zones adjacent to each power supply limit, and by switching each pole voltage to the power supply limit (Vmax) for a predetermined number of electrical degrees during each half cycle, resulting in step changes in the pole voltage waveforms from the substantially sinusoidal changing waveform to a fixed power supply limit. The waveforms of other associated poles are changed at the discontinuities in order to maintain a sinusoidal pole-to-pole voltage. The arrangement uses the d.c. source efficiently and recognises that modulation below 10% and above 90% is not possible. <IMAGE>
Patent GB-2171315-A (GB)
Title: External female urine collection systems
Inventor: HALL KENNETH F
IPC: A61F5/441
Filed: 1986-02-25
Abstract: An external female urine collection system includes a urinary device 130 and a urine collection vessel 190 separated by a flow control unit 200. The device 130 is a cup-shaped member adapted to be positioned within the labial folds of the user in contact with the vestibular tissue around the meatus. The device 130 thus has a cavity for receiving urine, the cavity being in flow communication with an anti-kinking drainage channel. The flow control unit 200 includes a valve housing 202 defining an inlet 204 and an outlet 206 and is capable of maintaining a preselected vacuum condition at the valve inlet 204 and a predetermined pressure condition at the valve outlet 206. A flow control element, such as a flapper-type valve element, prevents flow of urine back to the device 130. While the device 130 is held against the vestibular tissue by gentle vaccum, urine flowing through it entrains gas present in the cavity. However, the valve housing 202 includes a vent 240 covered by a hydrophobic semi-permeable membrane which permits air and other gas to diffuse therethrough, thereby counteracting the effects of entrainment and maintaining the vacuum condition at a predetermined level. Another vent 244 covered by another hydrophobic semi-permeable membrane allows dissipation of excessive positive gaseous pressure in the urine collection vessel 190 following de-entrainment of said gas from the urine. <IMAGE>

Title: Constructing paved area
Inventor: NEARY TERENCE EDWARD
IPC: E01C11/22
Filed: 1986-03-20
Abstract: When constructing a surfaced area a boundary between a roadway (14) and each of footpaths (16, 18) is firstly defined by a right-angled strip (32). The roadway (14) is surfaced up to the strip (32) to overlie the leg (36) thereof. Kerb edging components in the form of blocks (40) moulded from a cementitious material are laid with the vertical face of a lower shoulder (42) abutting the leg (34) of the strip (32) such that the horizontal face of the shoulder (42) overlies the edge of the surfaced road. The respective pavement area (16, 18) is then surfaced into an upper shoulder (44) of each block (40) to the level of the upper face of the block (40). The positioning of the roadway and the pavement areas within the shoulders of the blocks (40) creates an effective mechanical interlocking arrangement which avoids the need for haunching and consequently the mixing of concrete on site. <IMAGE>

Filed: 1986-11-20
Abstract: A rotatable spool fishing reel has a spool assembly, rotatable about a stub axle (17) mountable transversely on a fishing rod, in two separable parts. A line carrying part comprising a bobbin (12, 13, 16) with a cylindrical axial aperture holds the line, and is releasably fittable onto a cylindrical projecting core (20) of a drive part that fits rotatably onto the axle (17), one end of the core being fixed to an end plate (10) incorporating a drive handle (14) and a catch (19) for releasably retaining the drive part on the axle. The line-carrying and drive parts when assembled are rotationally fixed relative to each other, but are conveniently separable so that the line-carrying part may be exchanged for another carrying e.g. a different line without the need to change the entire spool. Flange 22 retains a leading edge of the line and edge groove 24 through which the line may be passed prevents the line from slipping. <IMAGE>
