Patent GB-2194641-A (GB)
Title: Continuous lossless monitoring of neonatal blood characteristics
Inventor: HEMMERT NANCY J
IPC: H01M10/48
Filed: 1987-02-23
Abstract: The blood is withdrawn from the patient, then is passed continuously in sensory relationship past sensors (35, 35', 35'', 38) for the characteristics to be monitored, and then is returned to the patient's cardiovascular system, in a lossless one-way flow path. Blood withdrawal and return through catheters (21, 27) preferably indwelling in respective arterial and venous vessels (20A, 20B), as in a neonate's umbilicus (20), enable real-time monitoring of the selected characteristics. The intermediate blood-transport passage (25, 25', 25'') constitutes also a semi-permeable membrane juxtaposable to the sensors for use and readily disposable, as are the catheters, after use to assure positive isolation of the blood of separate patients. Gases, charge carriers, and radiation can pass through the membrane as indicators of the characteristics being monitored.

Title: Optical transmission systems
Inventor: JANSSEN ADRIAN PERRIN
IPC: H04B10/67
Filed: 1988-05-27
Abstract: Automatic feedback control of the output power of a semiconductor laser employed in a transmitter of an optical transmission system, which also includes a receiver, involves use of both the transmitter and the receiver. The mean value of the power, as transmitted via a fibre (23), received by a photodiode (27) is compared with a predetermined value and the output of the laser (25) adjusted to achieve equalisation therewith. The necessary return link between the photodiode and the laser may comprise a second fibre, particularly the other fibre of a two-fibre duplex optical link, or may use the same fibre (23). The two fibres of such a link transmit respective data signals, output from respective semiconductor lasers, in opposite directions between the ends of the link. Each transmitted data signal is modulated at a low frequency whose value is indicative of the necessary change in the output of the semiconductor laser, at the other end of the link to the laser that is transmitting the respective data signal, which is required to equalise the received power with the predetermined level. <IMAGE>

Title: Measuring the profile of a roll in a rolling mill
Inventor: BRADSHAW TIMOTHY JOHN
IPC: G01B5/207
Filed: 1989-10-04
Abstract: Work rolls 30, 31 are separated to form a gap and measuring apparatus is located in the gap between the rolls. The apparatus includes a longitudinally displaceable carriage, the longitudinal position of which is determined by means of an encoder. Probes 23, 25 are displaceably mounted on the carriage to engage the periphery of the work rolls. Transducers 20, 21 sense the position of the probes. When the carriage is displaced in a direction parallel to the axes of the work rolls, signals generated by displacement of the transducers are coordinated with the longitudinal position of the carriage to generate the profile of at least one and preferably both of the work rolls. This is done without requiring the rolls to be removed from the mill housing. <IMAGE>

Title: Apparatus and method for feeding fibre material
Inventor: LEIFELD FERDINAND
IPC: D01G23/00
Filed: 1991-01-22
Abstract: In an apparatus for feeding fibre material, for example cotton, man-made fibres, in flock form to processing machines, such as carding machines, cleaners, there are provided a fibre reserve device (1) which leads into a take-in device consisting of a take-in roller (2) and a cooperating member (e.g. tray 13) and an opening device (e.g. a high-speed opener roller (3) which serves to receive fibre material from the take-in device and deliver it to a feed shaft (4). In order to enable the amount of fibre material passing through the gap between roller 2 and tray 13 to be changed, ensuring secure clamping of the fibre material, take-in roller (2) or tray 13 is movably resiliently biased by spring (15a) one towards the other. The cooperating member may also be a roller. A sensor (e.g. inductive displacement type) senses relative positions of roller 2 and tray 13 for adjusting an element of the apparatus. A chamber may receive fibres delivered by roller 3. The tray may have a low friction insert 13. <IMAGE>

Title: Process and apparatus for depositing laundry articles.
Inventor: STUHMEIER GUNTER
IPC: D06F89/00
Filed: 1991-10-24
Abstract: Folding apparatus is known in which the folded pieces of laundry are deposited in a single pile. This has the consequence that at least as many items of laundry of the same type must be folded as are required to make a pile. The invention aims to provide apparatus of this type with which items of laundry folded in different ways may be deposited on corresponding piles, according to their type (sorted) and without "skewness" (incorrect offset). …<??>According to the invention, a discharge conveyor (22) and a re-placing conveyor (23) are located following one another in a plane, and the re-placing conveyor (23) is associated with two different depositing ends for depositing folded items (67, 68) as required. This results in the items of laundry being sorted inside the stacking device (65). … <IMAGE> …
Patent GB-2400496-A (GB)
Title: Signal processing apparatus
Inventor: SUMMER BRENT
IPC: H01Q21/22
Filed: 1991-12-11
Abstract: A first set of signals from an array of irregularly - spaced antennae (11, 12, 13, 14, 15) are processed (30) to produce a second set of signals (60) which would have been produced by a corresponding array of regularly - spaced antennae (11, 2, 3, 4, 15). This permits processing by apparatus (7) designed for use with a regularly - spaced antenna array. Antenna elements may thereby be positioned according to site conditions rather than at exact predetermined distances, or defective channels can be compensated for. For signal transmission, a first set of signals suitable for applying to a uniformly - spaced antenna array is converted into a second set of signals suitable for applying to a non-uniformly spaced array, thereby producing the same effect as would have been produced had the first set of signals been applied to a uniformly - spaced array. The numbers of signals in the first and second sets may be different. Similar processing may be used on signals sampled in time at a non-uniform rate to produce an evenly spaced set of samples, such as in a Doppler radar using non-uniform pulse repetition intervals.
