Title: Security buckle for wrist watch metal bracelets
IPC: A44B11/22
Filed: 1980-09-15
Abstract: An improved security buckle for a wrist watch metal bracelet utilizes a first and second frame 1, 2 one mounted within the other, which are provided with a limited amount of relative sliding movement. A spur 15 of the first frame is in engagement with or is disengaged from a first traverse element 9 of the second frame when the two frames are respectively in a first and second relative position. An inflexible removable traverse element 3 is attached to the first frame and to a first portion 22 of the metal bracelet. A locking band 23 attached to a second portion of the metal bracelet passes under the first traverse 9 and is engageable with the spur 15 when the frames are in the second relative position and further passes through a space defined by the inflexible removable traverse element 3 and a second traverse-element 12 on the first frame when the frames are in the first relative position. The second frame includes a traverse portion 16 engaging with the inflexible removable traverse element 3 for locking the second frame work in the first relative position when the locking band is within the defined space. A protection plate 16 may be provided to protect a user's wrist from marks left by the buckle. <IMAGE>

Title: Disc reproducing system for compensating mechanical imperfections in disc
IPC: G11B3/00
Filed: 1978-12-12
Abstract: A cartridge has a main stylus 42, 44 tracking a modulated disc groove and a secondary stylus 70, 72 tracking unmodulated disc lands 9. The main stylus vibrates a moving iron armature 230 while the secondary stylus vibrates coils 232, whereby rumble information sensed by both styli cancels out. The styli have independent mountings 231, 233 such that the secondary stylus is the more compliant. The cancelling action may be achieved in various other ways such as mechanically coupling the styli or electrically cancelling the signals from transducers individual to the styli. <IMAGE>

Title: Gray shade operation of a large AC plasma display panel
IPC: H04N3/12
Filed: 1981-03-04
Abstract: A circuit for use with an AC plasma panel 70 provides gray shade or brightness variation at the discrete points on a displayed raster by varying the number of emitted light pulses within a flicker period. The analogue video signal at 12 is divided into a predetermined number of levels, each of which corresponds to a particular gray shade. The gray shade level for all of the discrete points along each row of the raster is stored in binary form in recirculating shift registers 30-37. All of the points along one column at a time are addressed simultaneously and the data bits from the recirculating shift registers are used to clock either erase pulses or write pulses, as required in each row, to all of the rows simultaneously as each column in turn is addressed 86. Accordingly, by addressing all of the row electrodes simultaneously, all of the discrete sites can be addressed a sufficient number of times within a flicker period to minimize any raster flicker. <IMAGE>

Title: Heat treatment of metals
IPC: C23C8/80
Filed: 1981-05-01
Abstract: Ferrous metal is treated by austenitic nitro-carburising in a heat treatment furnace. A suitable atmosphere is created by admitting to the furnace nitrogen; ammonia; and a liquid or vaporous organic compound of carbon, hydrogen and oxygen. The atmosphere is maintained at a temperature in the range 690 to 750 DEG C. The organic compound is typically methanol and the atmosphere typically comprises nitrogen, carbon monoxide, hydrogen and free ammonia as well as small amounts of methane, carbon dioxide and water vapour. After being removed from the furnace, the ferrous metal is quenched. It has an outer surface layer of white, scuff-resistant, epsilon compound and an inner carbo-nitrided case containing austenitic and martensitic zone. The ferrous metal may then be treated to convert austenite to martensite or lower bainite.

Title: Variable configuration hull
IPC: B63H5/125
Filed: 1981-05-07
Abstract: A power boat has a displacement hull which acquires the ability to plane when conditions are appropriate by having hull portions approximately amidships that are comparatively flat and comparatively horizontal and aft from which the hull narrows and steepens and sweeps to the water line, and by having a pair of displaceable surfaces 8 located in the aft hull portion which are moveable between extended and retracted positions about hinge lines 8a extending from points adjacent the stern near the centre line outwards and forwards to points near the water line. The hull has a first configuration in which the surfaces are in their retracted positions so that the hull forms a displacement hull, and a second configuration in which the surfaces are in their extended positions and cooperate with the amidships portions to form planing surfaces for the hull. A propeller 6 is retractable for sailing purposes and a forward centre plate is hinged for retraction when planing. <IMAGE>

Title: Catalyst composition, production and use
Inventor: MCMEEKING DR JOHN
IPC: C08F10/00
Filed: 1981-07-14
Abstract: A transition metal composition is obtained by reacting a support material with an organic magnesium compound, a boron, aluminium, silicon and/or tin ester compound of the formula    A(OR<1>)nR<1)<x-n>   and a transition metal compound, where    A is boron, aluminium, silicon or tin;    R<1> is a hydrocarbon radical;    n is one up to the valency of A; and    x is the valency of A. A Lewis Base compound may also be used in the process. The preferred procedure is to react the support with the magnesium compound, then with the specified ester compound, then with the optional Lewis Base compound and finally with the transition metal compound. The support material is typically alumina or silica. The organic magnesium compound is typically a dihydrocarbyl magnesium. The metal ester compound may be a trialkyl borate, an alkoxyaluminium compound, a tetraalkoxy silane or an alkyl tin alkoxide. The transition metal compound is typically titanium tetrachloride. The optional Lewis Base compound can be a carboxylic acid ester. The product obtained may be used as a catalyst component and mixed with an organic metal compound to give a catalyst for the polymerisation of monomers such as for example ethylene and propylene.

Title: Production of alloys by deposition from vapour and apparatus therefor
Inventor: GARDINER ROBERT WILLIAM
IPC: C23C14/22
Filed: 1984-09-21
Abstract: An alloy 40 produced by deposition of the constituents from the vapour phase onto a temperature controlled collector 10 within a vacuum chamber is peened by relatively hard rounded balls 38 directed at the surface during the deposition process. The purpose of the peening operation is to level the surface and to cause renucleation thereby minimising porosity due to shadowing by the growing metal crystals. A secondary purpose is to control the residual stresses in the deposit. The balls 38 are propelled at the deposited alloy by impeller 22 and brushes 33, 34 prevent loss of balls which are returned to peening device 12 via conduits. <IMAGE>

Patent GB-2170942-A (GB)
Title: Educational or activity aid
Inventor: FIGGIS DORNE
IPC: G09B19/00
Filed: 1985-02-07
Abstract: The invention aids those people who have difficulty using scissors, for example young children, by providing sheets of paper or card on which a shape A is defined. Surrounding shape A is a cutting line B spaced from the shape and excess material extends outwards from the cutting line B to the perimeter C of the sheet. An entry notch or recess X extends from the perimeter C to allow scissors more easily to be placed in a cutting position at or near the cutting line B. Additional notches Y<1>, Y<2>, and Y<3> may also extend in from the perimeter so that when scissors cut along line B to any one of the notches, that part of the excess material already passed by the scissors falls completely away from the shape A, so making it easier for subsequent cuts to follow the line. After being cut out the shape A may be used for e.g. shape recognition. <IMAGE>
