Patent GB-2128170-A (GB)
Title: Sheet feeding apparatus
Inventor: SMITH DAVID WALTER
IPC: B65H3/04
Filed: 1982-10-01
Abstract: A sheet feeding device (10) for separating a single sheet from a stack of sheets (14) and forwarding the separated sheet away from the stack employs an endless friction belt (12) cantilevered about a drive pulley (16) such that the unsupported end of the belt floats freely on a stack of documents or paper sheets (14) when the belt is in the feeding position. As the belt is driven about the pulley (16) the unsupported end of the belt pulls and advances the foremost sheet from the stack and advances it over a retard member (18) on which the unsupported end of the belt (12) also floats. Because the belt floats freely on the stack of sheets, the normal force is evenly distributed over the surface of the belt, intersheet coupling is minimized, and the belt is able to conform to changes in the paper and stack condition. An idler roller (28) supports the belt (12) only in its non-feed position. <IMAGE>

Title: A friction body for a radially acting friction system
Inventor: KLINK RAINER
IPC: F16D69/04
Filed: 1982-10-20
Abstract: A friction body 1 for a radially acting friction system such as a centrifugal clutch consists of a lining support and a friction lining attached thereon, and to make a positive connection between the friction body 1 and a friction body support, the ends 4 of the lining support are bent round as legs in a peripheral direction over the end faces of the friction-body support. The angle produced by the friction body and bent-round leg will be at most 90 DEG . The friction body is releasably mounted onto the friction- body support by sliding in the axial direction. It is especially favourable if the legs are bent once again outwards to form an L-shape and thereby to form abutments 206, 213 for the restoring springs 214. <IMAGE>

Title: Automatic control of the fuel supply to an internal combustion engine immediately after termination of fuel cut
Inventor: OTOBE YUTAKA
IPC: F02D41/12
Filed: 1983-05-27
Abstract: An internal combustion engine 1 has its fuel supply controlled in response to at least intake pipe pressure immediately after termination of a fuel cut operation. When a transition is detected from an operating condition requiring interruption of fuel supply to one requiring fuel supply to the engine, a value of the intake pipe pressure detected by pressure sensor means 8 is changed by a predetermined amount of a predetermined number of strokes after the transition. Preferably, the predetermined amount by which the intake passage absolute pressure is reduced corresponds to the difference between the values occurring at non-combustion operation of the engine and at normal combustion operation of the engine; the speed of the engine being the same. <IMAGE>

Title: Fuel injection pumping apparatus
Inventor: FENNE IVOR
IPC: F02M41/14
Filed: 1983-11-08
Abstract: A fuel injection pumping apparatus of the rotary distributor type has a distributor member 12 rotatable within an angularly adjustable sleeve 11 carried in the body 10 of the apparatus. The sleeve 11 is coupled to an angularly adjustable cam ring having internal lobes operable to impart pumping movement to a plunger carried in a bore in the distributor member. The distributor member has a delivery passage 22 connected to the bore for registration with outlets 16 in turn in the sleeve. The distributor member also has a further and restricted passage 29 which registers with the outlet which has just received fuel for the purpose of absorbing pressure waves which may be reflected back to the outlet from the associated injection nozzle. The fact that the sleeve and cam ring are connected to each other means that as timing variation is effected by moving the cam ring angularly the phasing between the outlets, the delivery passage and the further passage remains constant. <IMAGE>

Title: Multichannel current measuring apparatus
Inventor: YAMAGUCHI KEIKI
IPC: G01R19/25
Filed: 1984-01-12
Abstract: To achieve high speed current measurement in an X-ray computerized tomograph, off-sets are measured (when signal currents I1-In are not supplied) by closing switches Sr, S1-Sn to charge capacitors C1-Cn with any off-set currents. Switches S1-Sn are then opened in sequence to discharge capacitors C1-Cn through amplifier U and A/D converter 3 into memory 7. Sr and S1-Sn are then again closed simultaneously to repeat the cycle. The data stored in memory 7 is averaged for each channel in arithmetic unit 9 and returned to memory 7. When signal currents I1-In are supplied, a similar cycle is used but the signals received in sequence from the various channels pass to memory 5. Outputs from memories 5, 7 pass to arithemetic unit 11 which supplies a true signal from which any off-set portion has been removed. <IMAGE>

Title: Leak detecting matrix for heat exchangers
Inventor: WILSON JOHN E
IPC: G01M3/02
Filed: 1984-01-24
Abstract: A heat exchanger has a plurality of double walled heat exchange tubes 16, 16a and first and second tube sheets 14 each having a plurality of tube holes for mounting said tubes. Each end of each tube outer wall 32 is sealed onto the outside face 36 of the tube sheet 14 at its corresponding tube hole and the ends of the tube inner walls 30 are similarly sealed to the inner faces 34 of the tube sheets 14. The first and second tube sheets each have a plurality of internal, isolated passageways 38,46 communicating with the interspaces 32 of the tubes in a different associated one of primary and alternative subsets of tube 56,54 respectively. By monitoring at both tube sheets the combined leakage into the tube interspaces from each of the plurality of subsets of tubes, a leak can be isolated to that tube which is common to those subsets leaking at the pair of tube sheets. This isolation is readily obtained since the subsets monitored at each of the tube sheets are organized differently but from the same tubes. <IMAGE>
