Abstract: 1278288 Rotary fluid flowmeters L L POHL 28 Oct 1969 [28 Oct 1968] 52672/69 Heading F1F. A rotary fluid flowmeter comprising a turbine rotor 8 having a shaft 16 extending transversely to the flow directions, includes a circular inlet 2 tapering smoothly into a quadrangular crosssection throat of a venturi section 6 which opens into a main duct having at its outlet end a control vane 9 which at low flow-rates closes the duct. The fluid then flows through a branch duct 10 downstream of the rotor to again flow through the rotor to augment rotor rotation in the same direction and thence through a return duct 13 to rejoin the main duct past a control vane 14 which is mechanically coupled to the control vane 9 and at this time fully open. The vane 9 is spring-loaded so that at increased flow-rates it is opened against its spring and at the same time partially closes the vane 14. Fluid flow then being partially through the main duct and partially a reverse flow past the rotor and through the return duct. At high flowrates, the vane 9 is fully open and the vane 14 fully closed with all the flow passing through the main duct. By selecting the line of inclination of a guide vane 5, the throat area of the venturi, the venturi section 6 being replaceable by another section, and the loading of the spring the meter may be calibrated to give high sensitivity and linearity over a wide range of flow-rates. The shaft 16 is supported in jewel type bearings and the rotor is coupled to drive an index counter.

Filed: 1974-12-09
Abstract: 1459658 Coiling apparatus MOELLER & NEUMANN GmbH 9 Dec 1974 [24 Dec 1973] 53064/74 Heading D1T In the coil receiving apparatus shown a rotatable base plate 10 carries at its circumference a plurality of upstanding support structures 4 that together define the outer limit of the coiling space. Each support structure 4 carries an endless chain 1 connected to a coil receiving plate 5, the plate 5 being vertically displaceable by means of a shaft 11. At the start of a coil winding operation the plate 5 is at an upper setting and as the coils are deposited on the plate 5, which rotates with the support structures 4, the chains 1 move vertically with the coil receiving plate 5 and so prevent the outer side of the coil from being rubbed. The support structures 4 prevent the chains 1 from yielding in a radially outward direction. The base plate 10 also carries a series of upstanding pins 7 that pass through the coil receiving plate 5 and together define the inner limit of the coiling space. The base plate 10 is rotated via a hollow shaft 9.

Title: Magnetic recording apparatus
Inventor: BAILEY DAVID L
IPC: G11B20/14
Filed: 1970-11-13
Abstract: 1,259,938. Self-clocking digital recording systems. INTERNATIONAL BUSINESS MACHINES CORP. 13 Nov., 1970 [22 Dec., 1969], No. 54009/70. Heading G4C. A multi-track magnetic recording system ineludes a number of clock pulse generators, each associated with a respective track and being synchronized by self-clocking data read from the track. In the absence of data signals from a track the associated clock generator is synchronized by signals from one of the other tracks. In the embodiment illustrated there are 4 tracks and associated read/record channels 10- 13 connected to unit 18. Each channel is similar to that shown at 10 and comprises a data detection circuit 26, which passes data from the record to unit 18, and a synchronizing circuit including clock generator 29 which passes clock pulses to circuit 26. The signals from the associated track pass via gates 41, 44 to synchronize generator 29. Unit 32 detects the amplitude of the signal from the track and if it falls below a certain level, e.g. due to tape lift-off, it passes a signal to unit 18, which subsequently inhibits circuit 26. It also switches latch 40 to inhibit generator 29, inhibits gate 41, and enables counter 45 and gate 42. Gate 42 now passes signals from another track, preferably the adjacent track, both to the generator 29 and to counter 45. Upon the arrival of the third pulse from the new track, counter 45 switches latch 40 to its original state, so enabling generator 29 which now generates clock pulses synchronized by the signals from the new track. When data signals are again sensed by unit 32 a similar switch process occurs, the generator being inhibited until the third pulse from the associated track. If, when the signal in one track fails, the signal in the adjacent track also is absent the synchronizing signals are derived either from another track or from the clock pulse generator associated with another track. The frequencies of the track signals may be averaged to provide a sync. signal.
