Patent GB-2270682-A (GB)
Title: Device for detecting incorrect separation of sheets from a pile.
Inventor: BUCK HELMUT
IPC: B65H7/12
Filed: 1993-09-16
Abstract: When a sheet 6 is lifted from a pile 3, eg by suction head 7, a sensing device 10 having spaced limbs 14 and 15 is swung over the marginal edge of the sheet and non-contact, eg ultrasonic, means 17-20 measure the sheet thickness. If the measured thickness exceeds a predetermined value, eg if two sheets have been lifted, then a control circuit interrupts the sheet separating and the operation of a machine to which the sheets are supplied. Suction device 23 may hold the lower of two sheets while the upper is fed. This same device 23 may be used to position each sheet prior to thickness measuring. Parts 18 and 20 of the measuring means may also be used to scan pile height. A blower may fan the sheets to aid separation. <IMAGE>
Patent GB-2272844-A (GB)
Title: Plasmapherisis system
Inventor: KIRKCALDY ALISTAIR HENRY
IPC: B01D61/22
Filed: 1993-11-22
Abstract: Blood is taken in batches from a donor via needle 12 and fed by pump 10 to a cross-flow membrane filter 16, from which separated plasma is delivered to bag 18 and concentrated cells are drawn by another pump 14 and fed to a reservoir 20 in the form of a flexible bag. When bag 20 is full its contents are returned to the donor, by a third pump 22, through the same needle 12. Anti-coagulant is added to the blood by fourth pump 26. During the filtering step, pump 10 is run at constant speed while the speed of pump 14 is varied in response to signals from pressure monitors 42, 58 to maintain constant transmembrane pressure. A further sensor 32, however, will stop pump 10 if the pressure falls unduly in line 30 during filtering and will control pump 22 to prevent excess pressure during concentrate return, thus protecting the donor. <IMAGE>

Title: Friction clutch
Inventor: MAUCHER PAUL
IPC: F16D13/58
Filed: 1993-12-15
Abstract: A friction clutch 1, more particularly for motor vehicles, comprises a pressure plate 3 which is connected rotationally secured to a housing 2 but is axially displaceable a limited amount, and a diaphragm spring 4 which operates between the housing and pressure plate and through which the pressure plate can be biased in the direction of a clutch disc 8. The disc 8 can be clamped between this plate 3 and a counter pressure plate 6 and the clutch can be engaged and disengaged by operating means, with an adjustment means 17 automatically compensating for the wear of at least the friction linings of the clutch discs. The adjustment means 17 has two rings 18, 20 set radially spaced from each other and supported on the same component (cover, pressure plate), and each ring is displaceable axially in the direction of the diaphragm spring under the action of an adjustment device, such as a ramp unit 19, 21; 22, 23, which is rotatable circumferentially. The ring 18 is engaged by the spring 4 and the ring 20 is a wear detector ring and is engaged by a wear sensor 37. Indentations (26) (FIG 3) act as ventilator blades and together with openings (25) provide air cooling. <IMAGE>

Title: Ornamental picture frames
Inventor: DETENON ROBERT
IPC: B29C48/12
Filed: 1994-05-20
Abstract: Frame members 1 for picture frames are made by forming a plastics extrusion, cutting it into lengths and applying to the lengths of plastic extrusion a solvent based wood paste which is then moulded or otherwise shaped such that it forms ornamentation 2 on the surface of the plastics extrusion and it is then allowed to dry. This process makes use of the low cost of extrusion plastics moulding but enables the ornamental features that would otherwise only be obtainable by injection moulding to be obtained with the extension moulding. <IMAGE>

Title: Acoustic fluid flowmeter
Inventor: GILL MICHAEL JOHN
IPC: G01F1/66
Filed: 1991-09-11
Abstract: The flowmeter includes a housing with a duct 11 having an inlet (13, Figs. 1,3) and outlet (14). Fluid passes through a number of apertures 47 in a chamber 21 and then through a measuring tube 40 which incorporates extensions 41. Fluid exits via chamber 22 and its apertures 47 to outlet (14). Transducers 36, 37 are provided in chambers 53, 50 and have an acoustic path through the measuring tube. Control electronics cause the transducers to send a burst of signals in alternate directions through the tube to determine fluid speed. The measuring tube is arranged to increase the speed of fluid along part of the flow path. The extensions modify the fluid flow so as to reduce the generation of turbulence. The chambers 21, 22 with their apertures provide a labyrinth to provide a fluid path of reduced turbulence. <IMAGE>

Title: Insulated gate bipolar transistor
Inventor: SUMITA HITOSHI
IPC: H02M7/538
Filed: 1994-08-17
Abstract: In the collector portion 30 of the insulated gate bipolar transistorthere are provided, a p-type collector layer 33 diffused into an n-type semiconductor region 12, an n-type carrier extraction layer 35 diffused into the semiconductor region opposite to an emitter portion 20 and a field effect transistor portion having an auxiliary gate Ga disposed between the collector layer 33 and the carrier extraction layer 35. The field effect transistor portion is controlled by the auxiliary gate Ga in such a manner that during its "off" state the collector layer 33 is isolated from the carrier extraction layer 35, connected to a collector terminal C, to cause its potential to float so that the majority carriers flowing in a transverse direction below the collector layer 33 prevent minority carriers from being injected from the collector layer into the semiconductor region 12, thereby shortening the "off" operation time.   <IMAGE>
