Patent GB-2207734-A (GB)
Title: Torsional vibration damper
Inventor: FISCHER MATTHIAS
IPC: F16F15/127
Filed: 1988-08-04
Abstract: A torsional vibration damper of a clutch disc, is equipped with rubber-elastic end stops (11) which render possible a strongly progressive characteristic curve in the end zone of the maximum angular deflection. Due to the elastic end stops in the form of buffer pieces it is possible to realise a spring characteristic curve which is flatter on the whole and rises strongly progressively in the region of the end stops and thus, despite the flat spring characteristic curve, can transmit a high end moment. The elastic components further prevent undesired noises. <IMAGE>

Title: Rotating circular wing aircraft
Inventor: CHAPMAN MICHAEL JOHN LEIGH
IPC: B64C39/06
Filed: 1989-03-22
Abstract: A rotating circular wing aircraft comprises a standard aeroplane fuselage 1 fitted with conventional tailplane 2, fin and rudder 3, retractable landing gear 4 and conventional propulsion units 5, mounted at the rear or front of the fuselage. Rotating shaft 6 driven by low powered conventional motor 7 with variable speed, mounted on top of and clear of fuselage 1 within a streamlined cowling is in a forward position along the fuselage, the motor assembly and shaft being hydraulically tipable, driving the rotating circular wing 8 with generally smooth, flat surface, but curving concave downwards at the perimeter until perpendicular to the central flat portion to which it is rigidly fixed. Rotation of the circular wing during flight results in increased stability of the aircraft due to inertial forces and reduced drag while providing a high degree of lift, especially due to ground effect at low level. Fig 5 shows a version having four rotating circular wings 8. A tilt mechanism for the circular wing is described (Figs 8, 9). The configuration is applicable to a toy aeroplane (Fig 7) which may e.g. be launched by a catapult after the rotating wing has been spun up by means of a string (18) round a pulley (14) on the wing support shaft. <IMAGE>
Patent GB-2232735-A (GB)
Title: Twist fastener
Inventor: WILSON GORDON BRUCE
IPC: F16B7/14
Filed: 1989-03-29
Abstract: This fastener allows poles to be connected telescopically or elements to be joined by a male-female socket. The telescopic pole allows for two poles to be extended to any length and to be fixed at those lengths by rotation of one pole to another. The poles are prevented from sliding along their lengths in the fixed position by friction. Rotation of the poles engages contact between inner and outer poles as a result of the poles' geometrical cross sections. The male-female socket works using the same principle as the telescopic pole only the elements insert one in the other to a fixed depth. <IMAGE>

Patent GB-2236406-A (GB)
Title: Radiant heating system
Inventor: ARNOLD JOHN FRANK
IPC: G05D23/19
Filed: 1989-09-12
Abstract: A radiant heating system comprises a radiant heating tube 1 suspended in a building 2 and provided with burners 10 producing hot combustion gases which are drawn through the heating tube by pump 6 to heat the tube, the heat output of the burners being dependent upon the value of the negative pressure applied to the burners through the heating tube. The burners are arranged to have, at a predetermined normal operating value of negative pressure, a heat output calculated to maintain a desired temperature inside the building when the outside air temperature has a preselected value. The outside air temperature is sensed by a thermostat 8 during operation of the system and the value of the negative pressure applied to the burner means is increased by adjustable damping means 7, 11 when the outside air temperature falls below the preselected value, thereby increasing the heat output of the burner means to meet the increased thermal load. Constructing and operating the heating system in this way permits the capital cost of the system to be reduced in comparison to systems constructed and operated in a conventional manner. <IMAGE>

Title: High stability interferometer for measuring small changes in refractive index
Inventor: BARNES THOMAS HEINRICH
IPC: G01J9/02
Filed: 1990-02-05
Abstract: An interferometer for continuous measurement of small changes in the refractive index of a sample (10) has a diffraction grating (3) placed to be movable sideways or radially, and to diffract laser light into beams which include +1, -1 and zero order beams. The grating (3) is in the input plane of a Fourier Transform lens (4). The beams are brough to a focus in the output plane of the lens where they are reflected by a mirror (6). A spatial filter (5) stops all but the +1, -1 and zero order beams. The sample (10) is placed in the path of the +1 or -1 order beam. The reflected beams are diffracted again by the grating (3) and reflected by a beam splitter (2) through a further spatial filter (8) to isolate beams +1(a) and -1(b) which are directed to respective detectors (9a) and (b). Each beam comprises a different combination of interfering diffracted beams, and since only one of the beams includes light which has passed through the sample (10), the phase difference between the beams may be used to measure changes in the refractive index of the sample. …<IMAGE>…

Title: Multi-level linecoding
Inventor: LARGE TIMOTHY ANDREW
IPC: H04L25/49
Filed: 1990-03-16
Abstract: A method of linecoding binary digital non-return-to-zero (NRZ) encoded data on a multi-level code including the steps of d.c. biassing the NRZ data to change it into bipolar data and multiplying the bipolar data with a synchronous bipolar clock. This produces a 4-level code in which binary digits of one significance are encoded with biphase pulses of a first amplitude and binary digits of the other significance are encoded with biphase pulses of a second different amplitude. The resulting bit stream has no d.c. content. When applied to a conventional FSK heterodyne receiver the data will be correctly demodulated. Application is to FSK optical transmission systems using distributed feedback lasers. <IMAGE>

Patent GB-2238445-A (GB)
Title: Digital video coding
Inventor: KNEE MICHAEL JAMES
IPC: H04N7/50
Filed: 1990-09-12
Abstract: In a digital coder for video signals, transform means (such as a discrete cosine transform coder) operates on blocks of input samples or of difference values formed as the difference between input sample values and reference values to provide sets of co-efficients in the spatial frequency domain. A quantizer quantises the co-efficients and means responsive to the output of the quantizer produces the reference values. Criticality control means responsive to the output of the transform means determines the criticality of the picture areas corresponding to the blocks of input samples or difference values and controls the quantizer so that critical areas are coded differently to less critical areas. The criticality control means determines criticality in dependence on the number of co-efficient values in each set of such values having a magnitude above a predetermined threshold. <IMAGE>

A pivot point is selected at the centroid of the void or of a lower part thereof. The cutting line passes through the pivot point and its slope is set by reference to a weighted combination of the effect of the shape and size of the void and the shape and size of the callus. The weighted combination also varies quadratically with respect to the slope of a tentative cutting line through the void and the slope of the callus.
