Title: Piecing open-end spinning apparatus
Inventor: SMITH ALAN
IPC: D01H4/48
Filed: 1984-05-09
Abstract: A piecing-up system for an open-end spinner includes a friction drive roll 6 and a yarn store drum 12 which rotate the package in a direction to pay out yarn from the package and allow it to be wound onto the yarn store drum whereby the yarn store drum builds up a reserve which can subsequently be paid out during acceleration of the yarn package from rest. Resumption of fibre feed to the open-end spinning chamber is timed in relation to the depletion of the yarn store during paying-out, so that the instantaneous resumption of spinning and the more gradual acceleration of the yarn package do not result in excessive slack of spun yarn. <IMAGE>

Title: Palletized packing cases
Inventor: KELSO CLIFFORD WHITE
IPC: B65D19/20
Filed: 1984-09-19
Abstract: A fibre-board packing case which is made from a blank of fibre-board and has side walls 1 and 2 and the usual four bottom closure flaps hinged to and extending from each of the side walls, is provided with two additional bottom flaps 11 and 12. Each of these flaps has two portions 13, 14 and 19, 20, portions 13 and 19 being fixed to the sidewall 2 and the opposite side wall of the packing case. The portions 14 and 20 are each provided with three rectangular fibre-board tubes 16, 22, which are axially aligned with each other when the flaps are closed to allow elongated blocks of rigid foamed polystyrene to be inserted through the tubes 16 and 22. This holds the bottom flaps closed and the tubes form a pallet which is an integral part of the packing case. The provision of the tubes 16 and 22 on the additional flaps 11 and 12 and the fixing of the portions 13 and 19 of the additional flaps to the side walls of the packing case greatly increase the strength of the packing case and its resistance to damage by the forks of a fork-lift truck. <IMAGE>

Title: Improvements to the damaged and flooded stability of vessels with fully enclosed superstructures
Inventor: CORLETT BRIAN JAMES
IPC: B63B43/04
Filed: 1987-07-03
Abstract: In a sea-going vessel of the Ro-Ro type, the vehicle deck 11 is provided with bulkheads at intervals to prevent movement of water fore and aft which bulkheads are in place when the vessel is in transit but can be retracted or opened when the vessel is docked to allow the passage of vehicles on and off.

Title: Tape recorder of the automatic reversing type
Inventor: YOSHIMURA TOSHIO
IPC: G11B5/55
Filed: 1987-10-13
Abstract: An automatically reversable tape recorder wherein unintended loosening of azimuth adjusting screws can be prevented and stabilization of the frequency characteristic of a magnetic head attained comprises an abutting element 13 mounted for turning with a head 11, and a substantially U-shaped resilient stopper member 19 supported on a base 15. Stopper member 19 has azimuth adjusting portions 21 and stopping portions 22. Azimuth adjusting screws (23) (Fig 3) are screwed in base 15 and extend through openings 20 in azimuth adjusting portions 21 so that on tightening or loosening stopping portions 22 are adjusted. As abutting element 13 is turned, it is abutted with one of stopping portions 22, but an impact force will not be transmitted to azimuth adjusting portions 21 due to the resiliency of stopper member 19. Stopping portion 22 may alternatively extend parallel to the axis C or in an oblique direction. Head rotation is effected via a pivotal switching plate (36)(Fig 2) connected to a tape end detection mechanism. <IMAGE>

Patent GB-2217906-A (GB)
Title: Ion particle accelerometer
Inventor: MORRISH PETER MICHAEL JEFFERY
IPC: G01P15/08
Filed: 1988-04-29
Abstract: The accelerometer operates by sensing small changes in the time of flight of packets of heavy ion particles (5) which are fired at regular intervals at an electrical detector (7) in a tube (8). The ions travel at a suitably low velocity. Provided the tube (8) is either stationary or moving at constant velocity the flight time for the arrival of the packet at the detector is constant. However, when the tube is accelerated towards or away from the source of the ion particles (1) then the ion particles arrive at the detector moments earlier or later respectively. The position of the tube relative to the ion particles alters when the tube is accelerated while the ions are in the free-flight section (between (4) and (7)), with the actual path length of the ions in this section varying by a small amount which is dependent on the acceleration applied to the tube. The free-flight section of the ion particles has to be screened, e.g. by screens (6, 11), from any electrical and magnetic fields while the ion particles traverse the free flight section which has to be a near vacuum. Timer 12, set by clock 13, is started by a signal from gate 17 that also effects release of a bunch of ions 5 and the amplified signal from detector mesh 7 stops the timer; then computer system 15 determines the acceleration. The combination of three such orthogonally arranged tubes is discussed. The device can be used to determine the full navigational position of a craft when suitable computations are done on the ion particles' change of free-flight times on arrival at the detector. <IMAGE>

Title: Turning bankbook pages
Inventor: NAKATA TERUHIKO
IPC: B41J13/26
Filed: 1988-10-28
Abstract: The pages of books (1) e.g. bankbooks, are turned e.g. for printing thereon by a page turning mechanism having a page-turning roller (9,30), which includes a member or members (9a, 30a) formed of an elastic material having a large coefficient of friction and exhibiting a small change in pressure relative to changes in an amount of deformation, wherein the page-turning is effected by the force that is solely attributable to the change in pressure of that member. Alternatively, the book page turning mechanism may have a pad (20) formed of a material with a large coefficient of friction and disposed at a position opposing the page-turning roller, so as to enable the page-turning. <IMAGE>

Title: Improvements in or relating to a roll
Inventor: BRENDEL R BERNHARD
IPC: D21F3/08
Filed: 1989-06-14
Abstract: A roll comprises a stationary beam 3 and a rotatable shell 1 surrounding the beam at a position spaced therefrom. Pairs of sealing means 14, 14' are disposed on the beam in the gap between the beam and the shell, the sealing means of each pair being disposed on opposite sides of the beam, offset by 180 DEG  from one another. The gap between the beam and the internal surface of the shell is filled with pressure fluid at a predetermined pressure. The sealing means are mounted on the beam for radial movement and engage the internal surface of the shell. The sealing means define chambers open towards the internal surface of the shell, the chambers on one side of the beam being supplied with pressure fluid at a pressure higher than the pressure in the gap between the beam and the shell, whilst fluid is supplied to the chambers and on the other side of the beam at a pressure below the pressure in the gap. The resulting forces exerted on the shell are cumulative in the same direction.
