Title: Improvements in or relating to devices for counting sheets in stacks of sheets
Inventor: KONDRASHIN VIKTOR MIKHAILOVICH
IPC: G06M9/02
Filed: 1983-01-04
Abstract: A device for counting the number of sheets in a stack 9 comprises sheet separating assembly insertable between the sheets for separating each successive sheet in the stack. This sheet separating assembly has a bearing surface 4 for accommodating a sheet, a means 7 for carrying the sheet from one side to the other of the bearing surface past a counting station (14), e.g. employing a photo-electric device for counting the separated sheets and is provided with a slotted nozzle 5 communicating with a source 6 of compressed gas to produce a flat jet of gas directed along the bearing surface and such as to provide an underpressure in the proximity of the bearing surface to cause the sheets being separated from the stack of sheets to adjoin the bearing surface with a certain gap between the sheet and the bearing surface. Other embodiments (Figures 6-12) employ a rotating separator disc with the gas jet directed radially outwards in the region of a sheet separating finger (20). <IMAGE>

Title: Skeining device
Inventor: CINIGLIO ALEXANDER JAMES
IPC: B65H54/56
Filed: 1983-01-31
Abstract: A skeining device for reinforcing the ends of lengths of wire by skeining comprises front and rear retaining members 15, 21 and a shuttle (1) carrying wire guides (2). Wires pass from supplies, through tensioners 39, into the device via inlet holes 44 through guides 2 and out through hollow rotatable pin holders 10. To skein the wires, shuttle 1 is transported around a closed loop path by chains 3a, 3b. Wire guides pass around retaining members 15, 21 to retain wires on respective retaining members 15, 21. Front retaining members 15 are then rotated to twist respective multiplexed wires to form skeins. Rear members 21 are withdrawn through base plate 22 to strip the formed skeins therefrom, which are then withdrawn from the machine through the pin holders 10. Rear members 21 are independently retractable through base plate 22 to allow a member 21 to be withdrawn for the duration of a skeining operation, thus preventing the skeining of a respective wire, this facilitates testing the machine when setting up or after a wire has broken during use. The skeining device may have readily replaceable parts to adapt the machine for skeining different numbers of wires. <IMAGE>

Patent GB-2144523-A (GB)
Title: Sensor detonation arrangement
Inventor: SCHLOSS DR JURGEN
IPC: F42C13/00
Filed: 1984-07-02
Abstract: When obtaining a detonation signal 3 from the output signals 12 of several detectors 14, 17, preferably associated with different spectral regions it is ensured that combining the signals 12 does not prevent the triggering of the detonation signal 3 upon failure of a single signal 12 and even leads to greater target detection probability. Each digitised target signature (27) derived from a detector output signal 12 yields a detonation criterion 29 and an associated target probability criterion 30 derived from a spectral or other information comparison with predetermined criteria, and the detonation criteria 29 weighted with their target probability criteria 30 are additively combined in order to trigger the detonation signal 3 only when the summation reaches a threshold value. In order to take into account the target detection uncertainties at great target distances 21, a distance-dependent evaluation quantity 37, the value of which increases with the target approach, can be obtained by distance measuring equipment 38 from at least one of the detector output signals 12. <IMAGE>

Title: Apparatus for sensing fluids
Inventor: DEMISCH ULLRICH
IPC: G01N25/66
Filed: 1985-12-06
Abstract: Sensing apparatus, for example for sensing the dew-point, comprises a light guide (3) coupled to receive light from a light-emitting diode (1) and to pass light to a detector (2), for example, a photodiode, arranged to measure the light intensity. An area 3f of the surface of the light guide 3 is damaged, e.g. roughened, to produce an uneven area arranged to scatter light. When this uneven area is dry, this scattering causes light losses, which result in a reduction in the photocurrent measured by the diode (2). However, if the uneven area is wetted by a liquid, for example, by dew, then total reflection occurs to a large extent in this region and an increase in the current of the photodiode 2 results. The change in the photodiode current can be utilized to detect the presence of the liquid. <IMAGE>

Title: Propulsion system for an aerospace vehicle
Inventor: DENNING RALPH MURCH
IPC: F02K9/78
Filed: 1987-05-26
Abstract: A hybrid propulsion system for a transatmospheric or hypersonic cruise vehicle comprises a pre-cooled air-breathing jet engine 10 and a rocket motor 12. Previously ice formed on the inlet cooling heat exchanger 40 at altitudes where there is significant humidity sufficiently to deleteriously affect jet thrust. The rocket motor is therefore operated temporarily to compensate for the loss of jet thrust when icing is present and during defrost. The rocket motor is mounted co-axially with the jet pipe which exhausts through an annular orifice 36 into a common propelling nozzle 16. The arrangement avoids transverse thrust vectors as the relative engine thrusts vary which would cause the vehicle to pitch or yaw. The air inlet heat exchange is intermittently by-passed via line 50 to allow deicing. <IMAGE>
