IPC: A01F15/07
Filed: 1987-10-05
Abstract: An accordian pleated assembly of tubular, flexible, sheet material 50 (preferably plastic material), is deployed to form an extended tube by a device that consists essentially of an arched rigid framework 10-20 with a skin 21 of sheet metal extending over its upper part and carried on ground-engaging wheels and/or skids 30. The assembly of sheet material is mounted on a forward portion of the device, so that such material can be deployed into an extended tube at the rear of the device by pulling the latter forwardly along the ground, the free end of the tube having been suitably anchored at the starting location. An expandible ring 51 cooperates with an enlargement 41 on the device to ensure tension in the tube beyond the rear of the device. Cylindrical bales 53 of forage, are inserted from the front of the device through the framework and into the extended tube as it is formed by tractor- mounted mechanism 52. The bales are arranged end-for-end along the tube and in a triangular side-by-side and stacked relationship. Instead of the tube being kept erect by the simultaneous storage of bales or other goods therein, a separate support structure can be assembled in the tube as it is formed to produce a shelter that can either be used as temporary accommodation for human use (e.g. a first aid station in a disaster area) or for storage. If translucent plastic material is used the shelter can be adapted as a greenhouse. <IMAGE>

Title: Synchronising audio and video tape players
Inventor: MURRAY WILLIAM JOHN
IPC: G11B27/10
Filed: 1989-02-28
Abstract: In apparatus for synchronising audio and video tape players 10, 12 each reproducing a tape having a time code signal comprising a sequence of digital words each comprising data identifying a video frame, the time code signals are detected 18, 20 and frame pulse signals recovered from them are applied to phase detector 32 forming part of a phase locked loop 32, 12, 20 controlling the reproduction speed of one of the players whereby the reproduction speed of that player is synchronised with that of the other by phase locking between the frame pulse signals such that the two time code signals have a desired temporal relationship with one another. Higher frequency pulse signals (VDCLK/2, ADCLK/2) also are derived from the time code signals. In the event of failure to detect at least one of the time code signals, the one player 12 is driven 36 at a fixed speed. Upon resumption of detection of both time code signals after failure to detect one of them, synchronisation of the players is reestablished as follows. Fixed drive 36 is stopped from driving the one player 12 at the fixed speed, the further pulse signals (VDCLK/2, ADCLK/2) are applied to the phase detector 32 whereby the phase locked loop (PLL) establishes phase locking between them, and one or the other of the further pulse signals (VDCLK/2, ADCLK/2) is then repeatedly inverted whereby the PLL repeatedly establishes phase locking between them. When the repeated inversion has resulted in stepping of the phase relationship of the further pulse signals to the extent the two frame pulse signals synchronised and the two time code signals have the desired temporal relationship, the apparatus reverts to applying the frame pulse signals to phase detector 32.

Patent GB-2239826-A (GB)
Title: Dual-alloy disk system
Inventor: HYZAK JOHN M
IPC: F01D5/14
Filed: 1990-01-26
Abstract: Two pieces of metal are bonded together at a surface by placing the two pieces into contact at the surface and forging the two pieces in a die which causes substantial displacement of the metal originally at the surface in a direction parallel to and outwardly from the edges of the surface and into vents in the face of the die and within the die impressions. The strain and displacement fields are controlled by the die and vent geometry which is designed to concentrate the strain and displacement along the original bondline. In this way, up to 99.9 %+ of the defects which are potientially present at the original surface are efficiently displaced with moving metal away from the original contact between the two pieces of metal into sacrificial ribs that form in the vents and the remaining defects are subjected to significant strain. A portion of the displaced metal which contains many of the defects and which forms the sacrificial ribs is removed from the resulting bonded workpiece as the sacrificial ribs are removed from the workpiece. The result is a bond with superior properties and with a bond surface which can be located very precisely both in orientation and location (e.g., radial distance from the center of a disk). This system is particularly appropriate for forming dual-alloy high-pressure turbine disks for gas turbines in which an annular peripheral ring of a second superalloy is bonded to a central core of a first superalloy. The system is particularly effective if, prior to forging, surfaces to be bonded are closely shape-conforming, are very clean, and are diffusion-bonded using hot isostatic pressing while the surfaces are gas-free. The sacrificial ribs are formed by vents in the impressions of the forging dies. The vents are adjacent to the outer edges of the bond surface. The system may be accomplished by using one or more strikes in the same dies or same die geometry, or may include multiple strikes in which only one side of the bond is in proximity to a vent during each strike. Subsequent strikes would process the bondline resulting from the previous strikes, but with the rib removed. The die impressions would be so shaped that the resulting die cavity  would closely conform to the original workpiece shape, except for the vents, so that metal displacement and strain would be concentrated at the bondline.

Title: Torsional vibration damper
Inventor: COLDFORD TERRY
IPC: F16F15/126
Filed: 1990-03-20
Abstract: A torsional vibration damper comprises a flywheel ring (3) fixed to the outside circumference of a metallic hub (1) by a rubber spring ring (4), the hub (1) being provided on its side facing the spring ring (4) with a firmly adhesive, continuous coating (5) of thermosetting plastics material. The ratio of the average radial thickness (A) of the coating (5) to the average radial thickness (B) of the spring ring (4) lies within the range 0.25 to 3. The thermal expansion of the coating (5), arising during use, effects a radially directed prestress in the spring ring (4) of corresponding size. By this means, the spring ring always has largely conforming spring characteristics independent of the operating temperature. <IMAGE>
