Title: Rope descent regulator
Inventor: TAYLOR ANDREW WILLIAM
IPC: A62B1/06
Filed: 1987-06-30
Abstract: A rope descent regulator comprises a sheaf block comprising side plates 10, 11 pivotally connected at one end by a spring loaded pivot 12. Non-rotatable sheaf elements 13, 15 are mounted on plate 10, and 14 on plate 11. An arcuate slot is provided for a guide head on each sheaf element in the opposied plate. The plates are relatively rotatable to move sheaf element 14 in an arcuate path A relative to and between the sheaf elements 13, 15. A threaded rod or screw 19 running in a block 20 on plate 11 bears on sheaf element 13 so that the penetration of sheaf element 14 between elements 13, 15 can be preset, and thus the friction on a rope 23 which is reeved over the sheaf elements. <IMAGE>

Patent GB-2322986-A (GB)
Title: Target classification in radar systems
Inventor: HOMMEL HANS
IPC: G01S7/41
Filed: 1988-10-10
Abstract: A Doppler frequency spectrum derived by FFT from input radar echoes is analysed to determine the frequency of rotating blades. In the case of a helicopter rotar (identified by flight characteristics e.g. speed, height) this is generally sufficient to classify the target by comparison with stored data. For jet aircraft, the turbine blade frequencies are removed from the spectrum which is then inverse transformed. This enables frequencies corresponding to a complete rotation of the turbine wheel to be identified from the wheel and blade frequencies, the number of blades can be determined, to classify the target against stored library data.

Patent GB-886032-A (GB)
Abstract: 886,032. Finishing yarns. TLAMICHA, A.J. March 24, 1959 [March 24, 1958], No. 10103/59. Class 120(3) A monofilament or multifilament thread of synthetic material is uniformly roughened by one or more passages in contact with the peripheral surface of a rotating roughening body obliquely to the axis of rotation thereof so that the thread while being roughened is positively twisted many times about its own longitudinal axis. The roughening effect may be varied and controlled by changes in thread tension, the lap of the thread on the body, the oblique angle, the ratio between the running speed of the thread and the peripheral speed of the body and/or the direction of rotation of the body in relation to the linear travel of the thread. As shown, thread 1 from a bobbin 2 passes through an adjustable brake 6 and makes two passages over the roughening surface of a driven cylinder 4, on similar or opposite sides thereof, and is wound on a bobbin 3. A guide pulley 5 is movable relative to the rotational axis of the cylinder 4.

Title: Booster for a portable radio transmitter
Inventor: JOHNSTON RUSSELL DENIS
IPC: H04B1/38
Filed: 1990-01-12
Abstract: A booster (100) for increasing the power of the signal transmitted by a portable cellular telephone (10) comprises a variable frequency generator that reproduces the input frequency but without spurious signals. A transmission amplifier (7) is included between the transmission ports of the duplexers (4 and 6). Additionally a phase-locked loop (PLL) (20) is included between the duplexer (6) and amplifier (7). The voltage controlled oscillator (VCO) (19) of the PLL (20) reproduces (or tracks) the desired frequency of the input transmission signal, spurious signals being attenuated by appropriate selection of the PLL bandwith. The regenerated transmission signal is applied to the amplifier (7). The booster (100) thus selectively increases the desired transmission signal without correspondingly amplifying any spurious signals, i.e. spectral purity of the output signal is improved compared with known boosters. An automatic level control for transmission power may be provided. <IMAGE>

Filed: 1990-03-15
Abstract: A first method of characterising a yeast or other fungus comprises probing a restriction enzyme digest of the chromosomal DNA of the fungus with a probe which has a polyGT or polyCA sequence. A second method of characterising a yeast or other fungus to establish its relationship to a control fungus comprises probing a restriction enzyme digest of the chromosomal DNA of the fungus under investigation with a probe which will hybridise to a sequence which flanks, i.e. is within 5kb of, a poly GT sequence of the chromosomal DNA of the control fungus, and comparing the results with those obtained for the control fungus. The fungus to be characterised may be A. Nidulans or a Candida sub-species or may be a yeast such as Zygosaccharomyces bailii, Hansenula anomola or a Saccharomyces sub-species.
Patent GB-2243553-A (GB)
Title: Rectal block
Inventor: STEER PETER LESLIE
IPC: A61F2/958
Filed: 1990-04-30
Abstract: A rectal block device, for use when a patient is unable to avoid making uncontrolled faecal emissions of a largely liquid or slurry-like nature, includes a tubular member, for insertion through the anus into the lower bowl, which carries on its outer surface at least two inflatable cuffs. These cuffs are spaced longitudinally from one another along the tubular member. The device also includes control means for alternately inflating one or the other cuff into contact with the bowel wall so as to make a seal therewith. Tissue necrosis is substantially avoided because the area of tissue adjacent to one cuff is relieved of pressure while the other cuff effects the sealing function, and vice versa. <IMAGE>

Title: A single swing jaw crushing apparatus with an unobstructed feed opening
Inventor: DEDIEMAR RONALD B
IPC: B02C1/02
Filed: 1990-05-03
Abstract: The invention pertains to a single swing jaw-type crushing apparatus. Known apparatus suffer from the drawbacks of obstructing the feed opening of the crusher and rapidly wearing down the jaw plates of the crusher. The above problems are solved by providing an apparatus comprising a stationary jaw (33), a cantilevered swing jaw (35) driven by a toggle drive system (85), and a top feed opening (41) above the crushing chamber (37) formed between the two jaws. Two lateral hinge supports (49, 51) have a horizontal hinge axis (A) which lies in a plane generally bisecting the crushing chamber, so that the top feed opening extends behind hinge axis (A). A shock-absorbing back wall (143) is positioned behind hinge axis (A). The swing jaw (35) is fabricated in three sections, an upper hinge section (53), a lower jaw section (59), and an elongated joining member (61) attaching the upper hinge section (53) with the lower jaw section (59). Rock is fed into the crusher through the opening (41) and is then crushed between the stationary jaw (33) and the swing jaw (35).

Title: 3-D fractal video scanning systems
Inventor: SARGINSON PETER ASHLEY
IPC: H04N3/30
Filed: 1991-01-29
Abstract: in a system for scanning a sequence of images to produce an electrical signal for transmission, e.g. a television system, the image is scanned along a locus defined by one order of a hierarchical set of three-dimensional fractal curves, the three dimensions comprising two dimensions (H and V) in the image plane, and time (T). A set of receivers of decreasing complexity equipped with appropriate signal storage can display images of decreasing quality by selecting scanning patterns of decreasing order of the fractal curves. The quality decreases not just spatially, but also temporally, so as to equalise the subjective loss of quality spatially and temporally. An algorithm can be used to develop an order of increased complexity from a scan of lower order. <IMAGE>
