Patent GB-2201214-A (GB)
Title: Expansion anchor
Inventor: WHITE PETER JOHN
IPC: F16B13/06
Filed: 1987-02-13
Abstract: The invention relates to a set of parts, sleeve, insert 15 and expansion member 1, for providing an expansion anchor. The sleeve is formed from two separate members 8, each of which is substantially laminated that is to say it is laminated over more than 50% of its length. The member 8 is formed from a single planar blank of metal which is rectangular with projecting lateral wings or side pieces by folding the wings back over the rectangular part about a respective line 9 defined by the junction of each wing and bar. The initial free edges 10 of the wings 11 when the folding process is completed lie substantially parallel and adjacent centrally of the rectangular part. Tangs 13 on the sleeve prevent rotation thereof, when a threaded member is passed through the insert 15 and sleeve and turned in the expansion member 1 which is also threaded. <IMAGE>

Title: Reproduction of cinematographic images
Inventor: LING WILLIAM
IPC: G03B35/26
Filed: 1987-06-22
Abstract: A method of reproducing a ciné film in which each frame has a series of images of a scene recorded successively in light of different characteristics, the method comprising reproducing each frame of the film in a sequence of light of characteristics corresponding to those of the light in which successive images were formed on each frame of the film. Where the film consists of frames each having superimposed images formed successively in different colours, the film may be reproduced using a projector, with different colour filters movable successively in the optical path of the projector during each frame; preferably by mounting the filters in the shutter. The colours used for projection may be the same as, or complementary to, the colours in the ciné film.

Title: Pressure-sensitive copying sheets
Inventor: PARKER JOHN EDWARD
IPC: B41L1/36
Filed: 1987-10-14
Abstract: A CB sheet (1) of a CB/CF pressure sensitive copying sheet pair (1, 3) is coated on its surface which has the CB coating with a layer of dry carbon.

Patent GB-2205148-A (GB)
Title: Automatic one-way fluid valves
Inventor: ANDREN CHRISTOPHER ERIK
IPC: F16K17/19
Filed: 1986-01-20
Abstract: In an automatic one-way fluid valve, a radially facing inlet throat (50) is defined by annular seatings (48, 46) spaced axially apart and formed on a valve tube (14) and on an end closure cap (12). A thin, tubular, elastomeric valve diaphragm (52) presses resiliently at its respective borders against the seatings so as to close the throat and prevent fluid flow into the valve tube. A fall in fluid pressure in the valve tube below that in said throat withdraws parts of the diaphragm from the seatings to admit fluid to the valve tube. External fins (20) and internal fingers (36, 38) limit the deformation of the diaphragm parts in response to changes in the valve tube pressure. The diaphragm (52) is cylindrical or frusto-conical and is freely movable relative to both seatings. <IMAGE>

Patent GB-2226407-A (GB)
Title: Characterizing well features
Inventor: HOLZHAUSEN GARY R
IPC: E21B47/00
Filed: 1989-09-26
Abstract: A water or petroleum well is tested to obtain information about well features, especially that part of the well beneath the ground surface. Problems of irregularities in the well such as stuck tools, casing damage, damaged zones in an uncased well, or debris in a well, can be detected. 
<??>Oscillations are created in the fluid pressure in the well. Transducers measure the pressure oscillations, and the measured pressure oscillations are used to determine resonant frequencies. 
<??>The measured resonant frequencies are used to determine the characteristic impedance and the depth of each reflector in the well, after removing resonances caused by known reflectors. It is then possible to determine the nature of each unknown reflector based on suspected problems or the well's operational history.

Patent GB-2233909-A (GB)
Title: Golf club heads
Inventor: HANO NAOTO
IPC: A63B102/32
Filed: 1990-07-17
Abstract: Golf club heads have a distance (L) between the point of gravity center (O) of a head (H) and the longitudinal axis (X) of the club shaft extended in respect to prior art club heads, so that an axial moment of inertia about the shaft is greater. The golf club heads have advantageous effects that owing to great axial moment of inertia about the shaft, their ball-striking faces can be impacted against a ball without deviating upon swinging, and even when a ball is hit with a spot outside a sweet spot, the directional behaviour and driving distance of the struck ball are improved. <IMAGE>
