Title: Vibration Monitoring System.
IPC: G08B26/00
Filed: 1966-10-27
Abstract: 1,161,810. Measuring vibration electrically. RELIANCE ELECTRIC & ENG. CO. Oct. 27, 1966 [Jan. 20, 1966], No.48198/66. Heading G1N. [Also in Divisions G4 and H3] The velocity dependent output of a vibration transducer 12, Fig. 1, is integrated at 18 to give a displacement dependent signal which is compared with a reference value 24 in a differential amplifier 22, a zero output from which occurs when the reference value is reached and causes a bi-stable circuit 40 to switch on a relay 42, the amplifier 22 having an adjustable gain control 30 whereby the vibration amplitude at which the relay 42 operates may be selected. The output of the differential amplifier 22 is rectified in a detector 32, the output of which is fed both to an indicator, on line 48, calibrated in percentage of the reference level so as to give a continuous indication of the increase in vibration amplitude up to the pre-set limit, and also to a transient reject circuit 38 which rejects spurious high frequency transient components from the signal which operates the bi-stable "upper limit" sensor 40. The transient reject output is also supplied to a "lower limit" sensor, which is a bi-stable arranged to operate when the vibration amplitude drops below a reference level 41, thereby actuating a further relay 42'. The relays 42, 42' sound alarms, or shut down the machine of which the vibration is being measured. The output of the detector 32, may be supplied via a displacement calibrating potentiometer (also 218, Fig. 2, not shown) adjustable in synchronism with the gain control adjustment, 30, to a meter which indicates the actual amplitude of displacement. The detector 32 contains resistors (206, 216, Fig. 3, not shown) the ratio of which is selected to render the system responsive either to peak value of the displacement signal, or to average value thereof.

Title: Aerial prospecting
IPC: G01N1/22
Filed: 1973-10-23
Abstract: 1446760 Centrifugal separators COLUMBIA SCIENTIFIC INDUSTRIES Inc 23 Oct 1973 [27 Oct 1972] 49347/73 Heading B2P [Also in Division El] In a method of aerial prospecting for mineral deposits, a stream of particle-laden air is diverted from outside a flying aircraft 10, Fig. I, into a cyclone separator 12 mounted in the aircraft and by means of which the particles are concentrated by centrifugal force into a smaller volume, the particles being then deposited on a collector surface 23, Fig. 2, at a collector station 22 coupled to the cyclone separator. The stream of particle-laden air is scooped from beneath the aircraft by an inlet duct 14 connected to the cyclone separator, clean air from the cyclone being discharged to the ambient atmosphere by means of an exhaust duct 18. The collector surface 23 is of the adhesive type and is retained over the end of a collector tube 20 by means of a gasket 24 and an end cap 26 provided with a pressureequalizing aperture 27. In a modification, Fig. 4, the particle-laden air is scooped from below the aircraft base 36 by means of a U-shaped duct 30 in which the particles are driven against the outer wall of the duct by centrifugal force and are passed with a small portion of the air into the inlet duct 40 of a cyclone separator 34 whilst the bulk of the air is passed into an exhaust chamber 42 having exhaust ports 43-45 vented to the outside of the aircraft. A scoop 41 adjustable in depth and inclination aids in diverting the particles into the separator 34. Air is exhausted from the separator to the ambient atmosphere by means of a fan 50 driven by a variable speed motor 52 and mounted in a duct 48. The particles discharging at the apex 60 of the cyclone separator through a tube 66 are drawn against, and imbedded in, a filter tape 62 at a collector station 64 by means of a vacuum produced by a vacuum pump 72 connected to the station via a tank 73, a solenoid valve 90 and a tube 70. The tape 62 is moved intermittently by a stepped motor 74. A controller 80 controls the operation of the motor 74 and of the valve 90 such that the valve remains open to create a vacuum upon the tape 62 during a collection period when the tape is stationary and such that the valve is closed to release the vacuum when the motor 74 is energized to drive the tape to a new position. The particles collected over the collector surface 23 or on the tape 62 are subsequently analysed by X-ray transmission or fluorescence. Correlation of the analysis data with the geographical position of airborne collection can then be carried out.

Filed: 1975-12-11
Abstract: 1512089 Automatic exchange systems SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 11 Dec 1975 [19 Dec 1974] 50800/75 Heading H4K A tandem PCM, TDM exchange includes a signalling processor UCS which acts as an interface between a central control unit CC and signalling channels extending to a plurality of local exchanges CTE which use differing signalling codes, the processor being programmed to convert the different codes into a predetermined code and to send signalling information together with information identifying the local exchange from which the information was received to the central control. Transmissions from the local exchanges may be in PCM, FDM or analogue form and all signals are converted to PCM before being extended to the tandem switching network via which the access is obtained to the processor UCS, which processes all encoded signals in PCM form. No details are given as to how the codes are converted although details of the processor UCS are given, Fig. 2. It works on a 32 channel multiplex handling signalling codes from up to 31, 32 channel PCM highways, each highway having its signalling information carried in channel 16. The 32<SP>nd</SP> channel the process is used to extract synch information which enables the processor to identify the channel positions associated with particular highways and hence with particular remote exchanges. The synch signals also indicate the position within a superframe of 30 frames so as to enable the identification of the signalling codes relating to any one channel on a particular highway. Signaling codes received from the network or highway r are entered into a random access memory MS at a position defined by the address of the speed slot to which it relates. A processing unit EL cyclically scans memory MS and performs a code conversion on the signalling codes according to their address in the memory MS. A message comprising the converted code and the address is then written into buffer store MB from which it is read out to the central control over highway C via logic network RL 2 . A similar process takes place for signalling messages from the central code to particular highways. Further details of processing unit EL and its memory are given with reference to Figs. 4-6, not shown.
