Abstract: ABSTRACT A piezoelectric sensor for measuring an external force is disclosed which is accommodated in a cassette through a sealing member and provided with a pair of electrodes which are respectively bonded to opposite sides of a piezoelectric element.  A masking strip made of a highly insulative material covers the whole area of an end face of the piezoelectric element, which is exposed to the outside of the sensor, and a desired width of an end face of each of the electrodes adjacent to the end face of the piezoelectric element.  This maintains a high resistance between the electrodes having the piezoelectric element therebetween and thereby promotes accurate measurement without being effected by changes in the resistance of the sealing member due to temperature variation.  The sensor is effectively applicable to a vortex flow meter.

Abstract: A B S T R A C T            METHOD AND MEANS FOR SURVEYING POSITIONS             OF MOORING LINES      Means are provided for surveying positions of mooring lines extending between a moored structure and anchors in the water bottom. The means comprise a rotatable submarine transducer assembly including acoustic pulse transmitting means and an array of acoustic receivers, a support for locating the transducer assembly at a predetermined level above the water bottom and actuator means for rotating said assembly about a vertical axis relative to the support.     During operation the transmitting means produce a beam of acoustic pulses. Pulse reflections originating from mooring line sections that are successively scanned by said beam are received by the acoustic receivers, and the position of each scanned mooring line section is calculated by a processor unit on the basis of the time intervals at which said pulses are received after transmission.

Abstract: FULLY COMPATIBLE HIGH DEFINITION TELEVISION            Abstract A fully compatible high definition signal, which can still be received with conventional resolution by conventional TV receivers without auxiliary apparatus is provided by the present invention.  One TV channel carries the conventional TV signal while high frequency luminance and chrominance information is provided in a second TV channel.  The baseband signal containing the high frequency components is derived from the lower sideband output of a product modulator whose inputs are taken from an anti-alias filtered (camera) source of wideband luminance information and a local oscillator whose frequency is a multiple of the conventional chrominance subcarrier frequency embedded in the conventional baseband signal for the other channel.          Band-limited portions of the high-frequency chrominance information are multiplexed between alternate horizontal lines and modulated by a signal which is, effectively, an odd multiple of one-quarter the line rate to provide a single sideband spectrum that non-interferingly interleaves the high frequency luminance spectra.

Abstract: GAS FUSE     ABSTRACT OF THE DISCLOSURE         A gas safety valve is provided which has a valve chamber within a housing, and a gas inlet and outlet respectively communicating with an inlet and outlet end of the valve chamber.  Valve means are disposed in the valve chamber for allowing gas to flow from the inlet to the outlet when the valve means is in an open position, and preventing qas flow when the valve means is in a closed position at either end of the valve chamber.  The valve means may comprise a piston having a tortuous gas transmitting opening therein, the resist-ance to gas flow caused by the tortuous opening render-ing the valve means responsive to slight variations in . gas pressure differential between the inlet and the outlet. Resilient means are provided which extend between the outlet and the valve means.  The resilient means urge the valve means into the open position, and allow it to reversibly move to a closed position against the outlet when the pressure differential between the inlet and outlet of the valve chamber becomes suffi-ciently high to overcome the resistance of the resilient means .

Abstract: METHOD OF PREPARING POLYORGANOSILOXANE EMULSIONS               HAVING SMALL PARTICLE SIZE                       ABSTRACT           A method of preparing fine polyorganosiloxane emulsions with an average particle size of less than 0.3 micron and polyorganosiloxane microemulsions with an average particle size of less than 0.14 micron is described.   A translucent oil concentrate is prepared by mixing a polyorganosiloxane which contains polar groups, a surfactant which is insoluble in the polyorganosiloxane, and sufficient water to obtain a translucent mixture.  The translucent oil concentrate is then rapidly dispersed in water to form the desired fine emulsion or microemulsion.  In general if the translucent oil concentrate is not transparent a fine emulsion with an average particle size of less than 0. micron is obtained; whereas, if the oil concentrate is transparent, a microemulsion with an average particle size of less than 0.14 micron is obtained.

Abstract: ABSTRACT OF THE DISCLOSURE     A method of construction is provided in which a casing or assemblage of casings which can be handled as a unit is partly immersed in water to a controlled variable depth and used to mould a self-hardenable material such as freshly mixed concrete to form a required shape while isolating it from the surrounding water.          Throughout this stage of construction hydrostatic pressure exerted by the water on the casing or casing assemblage acts in opposition to pressure exerted by the self-harden-able material or by a temporary substitute therefor, (e.g. a bontonite slurry) together with any other forces or pressures that may act.   This enables casings to be used which otherwise and for construction in a dry environment would require substantial or extensive support from falsework in order to prevent fracture or undesirable deformation thereof.

Abstract: TRANSMITTING SEQUENCE NUMBERS OF INFORMATION      IN A PACKET DATA TRANSMISSION SYSTEM     Abstract of the disclosure In a packet data transmission system, correctly received information packets are acknowledged by piggybacking their sequence numbers onto information packets being transmitted.  The control field of each information packet includes a bit which indicates whether or not there is a piggybacked acknowledgement. Acknowledgements can also be transmitted separately in control packets having no information field.  Each acknowledgement consists of not only the sequence number of a correctly received information packet, but also the acknowledgement status of a plurality of preceding information packets whereby these can be negatively acknowledged if necessary.  The sequence numbers can have any one of three different sizes, for efficient transmission of sequence numbers on transmission links of arbitrary transmission speed and length (and hence delay). The sequence number size which is used on any particular transmission link is determined on set-up of the link in dependence upon the transmission speed and the round-trip delay of the link.
