Title: Apparatus for mooring a floating installation to a marine installation
Inventor: DELAMARE GUY ROBERT
IPC: B63B22/02
Filed: 1982-06-22
Abstract: Apparatus for mooring a ship (1) to a buoy (2) includes an arm (5) pivoted to the ship at one end (8a) and having a ring (9) mounted to its other end about a horizontal axis (10). The ring (9) mounts two vertically-spaced trains of wheels (15, 16), the trains being cooperable with respective surfaces (18, 19) of a rolling track (17) of the buoy (2) when the ship is moored thereto. The wheels (16) are eccentrically mounted whereby they can be rotated beyond the maximum diameter (20) of the ring (9), whereupon, by means of a winch (23) on board the ship (1) and a cable 24, the ring can be raised to a position (9r) thereby rapidly to un-moor the ship (1) from the buoy (2.) <IMAGE>

Title: Valve assembly with integral plastic spring
Inventor: KNICKERBOCKER MICHAEL G
IPC: B65D83/14
Filed: 1982-01-12
Abstract: A valve assembly for use with an aerosol container having an integral plastic spring acting between the valve stem (30) and the valve body (14). A problem in the art has been the production of low cost reliable valves for aerosol containers. The solution presented by this invention is to eliminate the use of a separate spring by providing a plurality of resilient legs exending from either the valve stem base or the valve body (14). The valve body (14) is disposed within the aerosol container adjacent a sealing gasket (18) having a central aperture (26) for receiving a valve stem extending therethrough. The valve stem has a valve stem sealing base for movement within an internal body cavity (16) of the valve body (14) to seal the valve stem (30) when the base engages the sealing gasket (18) and for enabling fluid flow when the base is displaced from the sealing gasket (18). The invention incorporates resilient means which may comprise a plurality of resilient legs (44, 46, 48, 50) extending from either the valve stem base or the valve body (14) for cooperation with an inclined surface (60) either being a tapered or curved surface extending from the other of the valve stem base or the valve body (14) to bias the stem sealer into engagement with the sealing gasket (18).

Title: Forming methods and apparatus for sections with sharp edges fabricated from composite materials and sections formed thereby
Inventor: MOBBS PETER JAMES
IPC: B29C37/00
Filed: 1982-09-28
Abstract: Fibre reinforced plastics composites may be formed into channel sections using female moulds. In using a female mould for a channel section it is difficult to obtain satisfactory characteristics at the channel edges due to bridging. The present invention provides a method of forming a channel section using a female mould, on the internal surface of which in the regions of the edges are provided slits. The pressure in the slits is maintained at a lower level than that used to force the material being moulded into the shape of the mould. The present invention obviates the problem of bridging.

Title: A decimal operand processing unit
Inventor: KINDELL JERRY L
IPC: G06F7/48
Filed: 1982-11-12
Abstract: In a microprogrammed data section processing system, the throughput of the system is increased by decimal operand processing apparatus which counts the number of effective digits in an operand which is the result of a decimal numeric instruction being processed by the system. The apparatus receives operand words the operand's least significant word first, in response to a predetermined microword. The decimal operand processing apparatus includes a first register which stores a count of one less than the number of words received; an adder which increments the output of the first register if the word received has a decimal zero in the high horder position of the word; and a second register which stores the output of the adder in a word count portion and the number of leading zeros in a digit count portion of the second register. The second register is loaded on the same cycle the word is processed providing the word does not contain all decimal zeros. <IMAGE>

Title: Injection molding a liner onto spool
Inventor: DAVIS JAMES W
IPC: B29C45/27
Filed: 1983-04-06
Abstract: Apparatus is described for injection- molding an insulating liner onto a metal spool for use in an electromagnetic flowmeter. The spool is composed of a cylindrical body 10, having end flanges 11, 12 and a pair of diametrically- opposed circular bosses 13, 14 to receive the meter electrodes. To carry out injection-molding, the spool is supported within a mold which defines a liner cavity 22 conforming to the inner surface of the cylindrical body and to the faces of the end flanges, the liner cavity 22 communicating with cavities 24, 25 conforming to the inner surface of the electrode bosses. The molding material is injected into a sprue 16 which runs along the longitudinal axis of the spool toward the hub 18 of a runner 19 extending radially toward an axi-symmetric ring gate 21 opening into the liner cavity at a point adjacent the boss cavities 24, 25. The molding material passing through the ring gate then flows in opposite directions in the liner cavity 22 to evenly fill this cavity as well as the boss cavities without creating weld lines therein. Shrinkage of the liner in the radial direction of the spool is compensated for by injecting thermosetting material into the resultant gap between the liner and spool body 10. <IMAGE>

Title: Forming holes in vitreous sheets
Inventor: LEDROIT RENE
IPC: C03B33/033
Filed: 1983-05-13
Abstract: A hole may be formed in a vitreous sheet 1 by fracturing the vitreous material, e.g. using a laser, along a closed path and removing vitreous material 11 circumscribed by that path from the surround 13 to leave a hole in the sheet. After fracturing the vitreous material, the circumscribed plug 11 is placed in contact with a heat sink 26 at low temperature so that the plug 11 contracts to afford clearance between it and the surround 13 to permit removal. The heat sink may be cooled with carbon dioxide, liquid nitrogen, technical grade neon or other coolants depending on the temperature desired. <IMAGE>

Title: Electromagnetic projectile launcher with explosive-start and plasma drive
Inventor: ROSS DAVID PATRICK
IPC: F41F1/00
Filed: 1983-07-04
Abstract: An electromagnetic projectile launcher with an insulating cartridge 22 having an internal pressure chamber 24 and an aperture for receiving a projectile assembly 26, 28. A fuse element 30 within the pressure chamber is electrically connected to a pair of generally parallel conductive launcher rails 18, 20. Current flow through the fuse element causes it to explode and create a high pressure plasma within the pressure chamber. This high pressure plasma forces the projectile assembly to accelerate away from the cartridge and later serves as a means for conducting current between the conductive rails and for propelling the projectile assembly along the rails. The fuse element 30 comprises a plurality of metal fibres or a strand of copper wire. <IMAGE>

Title: A stitch unravelling device for flat needle bed knitting machines
Inventor: WILSON TREVOR ERNEST
IPC: D04B19/00
Filed: 1984-02-22
Abstract: A device for mechanically unravelling stitches in a workpiece knitted on a flat bed knitting machine comprises a generally plane slipper (30) adapted to traverse the needle bed and to be guided by the rigid rectilinear guide formation which guides the knitting head. The slipper has a cam groove on its underside adapted to engage each active needle in turn during its traverse of the bed and to reciprocate it through a distance less than that required to advance the tip of the latch when open through the loop of a stitch on the needle. The front edge of the slipper overlies the hooks of the active needles and has a notch (46) to receive and guide yarn being disengaged from the needles. The yarn is passed through approximately 90 DEG  round a post (50) on the upper face of the slipper and drawn by hand along the machine to unravel the stitches by drawing the slipper with it. <IMAGE>

Patent GB-2156621-A (GB)
Title: Optical fibre receiver
Inventor: CHOWN DAVID PHILIP MARTIN
IPC: H04B10/69
Filed: 1984-03-27
Abstract: In an optical fibre receiver, the modulated light falls on a p-i-n diode (PD) connected to the input of an operational amplifier (A). This amplifier is shunted by a load resistor (R), which in turn is shunted by a non-linear Schottky diode (SD). This provides the receiver with a low pass response having a relatively long time constant. In addition to this, the a.c. coupling response for the connection to the next stage of the system has a relatively short time constant. These two time constants combine to give an overall characteristic with a relatively narrow bandwidth. This prevents a large pulse from spoiling the sensitivity of the receiver to a following smaller pulse. <IMAGE>
