Title: Scaffolding fastening; tamper proof nuts
Inventor: MCDONALD JOHN MOONEY
IPC: F16B23/00
Filed: 1990-11-20
Abstract: For use in association with scaffolding fastenings, there is proposed a tamper-proof lock means consisting of a nut (14) for engagement with a clamping screw (11), the nut (14) having a non-standard driving recess (15) at one end, and carrying a freely-rotatable captive sleeve (16) which extends beyond the inner end of the nut (14) to form a shroud (21) for enclosing or covering an adjacent nut (12) to make the latter inaccessible. The sleeve (16) is captive by virtue of a stepped or shouldered configuration (19, 20); and the sleeve is also provided with a retaining screw (17) of which the inner end is received within an annular recess (18). The screw (17) serves to hold the relatively rotatable components together particularly when not in use. The lock means greatly reduces the ease with which unauthorised persons can interfere with scaffolding fastenings. <IMAGE>

Patent GB-2246498-A (GB)
Title: Preparing a seed bed
Inventor: BOWSER FRANCIS JAMES
IPC: A01B49/06
Filed: 1991-07-02
Abstract: An agricultural implement comprises an implement frame having front packer means 16, intermediate carriage wheels 26 and rearwardly mounted power cultivator means 18, drill means 22 and rear packer means 24. The frame is fully trailed from a tractor drawhook or clevis. Lowering the wheels 26 enables the entire implement to be fully trailed whereby transport is simplified. Raising the wheels 26 relative to the frame causes the overhung weight of the rearward part of the implement to act on the packer wheels to increase their packing action by a lever effect arising from the fixed height of the tractor clevis. The packer increases the effectiveness of the power cultivator. <IMAGE>

Patent GB-2270889-A (GB)
Title: Active suspension
Inventor: TANIGUCHI YASUTAKA
IPC: B60G17/0165
Filed: 1993-09-17
Abstract: A pneumatic active suspension apparatus is provided wherein, when a sprung vertical acceleration (ZG), which causes a wafting phenomenon perceptible by a person in a vehicle, occurs during travel of the vehicle, supply/discharge of air to/from air spring chambers of suspension units is carried out for a supply/discharge control time determined based on the maximum value (ZGmax) of the sprung vertical acceleration. The supply/discharge control is started at an advanced time based on the sprung acceleration whose phase is advanced by 90 degrees from that of the sprung velocity, to thereby produce a force acting to cancel out the sprung vertical velocity at proper timing. As a result, the operation delay of the suspension apparatus is compensated for and the sprung vertical motion is suppressed. <IMAGE>

Title: Diffusing and depixelating means
Inventor: PHILLIPS NICHOLAS JOHN
IPC: G03B21/62
Filed: 1993-10-08
Abstract: An image display arrangement comprising a collimating fibre-optic plate 20 e.g. forming the screen of a c.r.t. display tube 12 and coated with a phosphor 22, has, on one side thereof a layer 30 of a photopolymer having formed therein an array of integral graded refractive index (GRIN) lenses 32, in register with the end face, of a respective optic fibre 24 of the fibre optic plate. Each GRIN lens is of a power such as to enhance the collimating effect of the respective optic fibre. A diffusion layer 34 is preferably superimposed on the layer 30, to impart a controlled diffusion to light passing through layer 30, such as to render invisible or less visible opaque regions 28, between adjoining optical fibres 24. The invention thus reduces or eliminates the so-called "chicken wire" effect. The GRIN lens array may be made by applying a p/p layer to fibre-optic plate 20 and exposing through the plate using the c.r.t tube. <IMAGE>

Title: Lampholder
Inventor: DOHERTY PATRICK JOHN
IPC: H01R33/965
Filed: 1993-11-15
Abstract: A lampholder comprises a hollow housing (10) which defines "J" type slots (11) along which the bayonet pins of a bulb slide during insertion and removal of the bulb. A rotatable member (50) has straight slots (52) which are arranged such that insertion of a bulb causes the rotatable member (50) to rotate between first and second positions. A contact carrier (40) in the housing (10) engages bulb engaging contacts (30) and bridging contacts (36) which are capable of effecting an electrical connection between power supply terminals (71) and the bulb engaging contacts (36). The contact carrier (40) is capable of obstructing rotation of the rotatable member (50) and is arranged so that, when in its second position, it is transversely or pivotally moveable upon rotation of the rotatable member (50) by the bulb to effect transverse displacement of the bridging contacts (36) to either engage or disengage the power supply terminals (71). In this way, rotation of the bulb makes and breaks the electrical connection between the power supply is terminals (71) and bulb engaging contacts (30). <IMAGE>

Filed: 1994-08-18
Abstract: A system for contracting bit map image data by deletion of pixel rows and/or columns allows interactive correction of an image that has been brought out of shape or lost zone essential detail when the bit image data are contracted at a certain magnification. The system includes a memory for storing original bit map image data and contracted bit map image data, and a decimating unit for decimating from the original bit map image data dot data at decimating positions in rows and/or columns which have been determined in advance according to a given contraction ratio. The display unit (30) displays both the original bit map image (33) default rows and/or columns (36) and the resulting decimating, the contracting bit map image (34), the user changes the deleted rows and/or columns by means of a shift indicating unit (35) for indicating a shift of the decimating positions while viewing the resultant contracted image. The system permits the operator to shift the decimating positions in an interactive manner for minimizing any loss in the contracted bit map image of major figure elements contained in the original bit map image. <IMAGE>

Title: Analysing crystalline materials
Inventor: ITO TATSUYA
IPC: G01N23/20
Filed: 1994-10-27
Abstract: In a method of analysing the structure of a crystalline material, first, data of a structure of a crystal as a target for space group-determination is read, and the data of the structure of the target crystal is compared with data of crystal structures stored in a memory (3), which are classified into crystal systems according to lattice constants and other conditions, to determine a crystal system to which the target crystal belongs (step S101). Then, space groups included in the crystal system are obtained by extracting them from a memory (4), and packing processing is sequentially performed by the use of the space groups (step S102). More specifically, arithmetic operations are performed on the lattice coordinates of each atom constituting the structure (unit cell) of the target crystal by the use of matrices corresponding to the space groups obtained to thereby determine equivalent positions of each atom. Then, at step S103, each of a plurality of transformed crystal structures obtained by the above packing processing is compared with the structure of the target crystal. When the former agrees with the latter, a space group giving such results is determined to be descriptive of the structure of the target crystal. The data of the space group is displayed on a display (5). The method may also involve predicting the results of x-ray diffraction, and comparing these with measured results to improve the approximation. <IMAGE>
