Title: Surface acoustic wave filter/discriminator
Inventor: DWYER DOUGLAS FRANK GEORGE
IPC: H03D3/16
Filed: 1982-02-02
Abstract: A surface acoustic wave (SAW) filter discriminator device comprising a piezoelectric substrate 10 on which are formed an r.f. input electro-acoustic transducer 11 and two output acoustic- electric transducers 12, 13. Transducers 12 and 13 are at different distances from the input transducer 11 to provide a predetermined delay in their r.f. outputs. The two outputs are combined in a non-linear circuit 14 to provide a voltage which varies as function of frequency, thereby performing a discriminator function. The output of one transducer 12 alone provides a filter function. An alternative structure is disclosed in which two transducers are tuned to a carrier frequency and a third transducer is tuned to an offset frequency. <IMAGE>

Title: Mixing and feeding plastics material
Inventor: SCHMITZ HORST
IPC: B29B7/28
Filed: 1983-09-29
Abstract: The device forms a mixture in a mixing chamber (1) and feeds it into a channel (12), which directly adjoins this chamber but is at an angle of e.g. 90 DEG , thereto for calming the turbulent flow. The mixing chamber (1) and the channel (12) each has a reciprocatable piston (3 or 14) for discharging the mixture contained therein after the feeding of the components has ceased and for cleaning the mixture chamber and channel walls. The free end of the piston (14) provided in the channel (12) assumes the function of a restriction piece (15) for restricting discharge front the mixing chamber in that this piston can be fixed in a specific position in the zone of the transition from the mixing chamber to the channel. This restricting position can be arbitrarily cancelled in that the piston provided in the channel can be fully retracted to such an extent that a restriction no longer takes place, when, at the end of the mixing operation, it is required to leave all integral surfaces of the device clean. Retraction is enabled by retraction of a back stop (25a). <IMAGE>

Title: Measurement of flowrate
Inventor: CORNHILL COLIN VICTOR
IPC: G01F1/66
Filed: 1983-10-12
Abstract: A non-obstructive flowmeter comprises a tube (11) for the passage of a fluid (liquid or gaseous), the internal wall of which is provided with passive acoustic signal-generating means, preferably a series of at least 5 ridged corrugations (12). An electroacoustic transducer (13) senses the signal. The transducer may be remote from the acoustic signal generating means and may be in the form of either a piezoelectric ceramic or a piezoelectric polymer foil. Preferably the amplitude of the acoustic signal is proportional to flowrate. The output signal (14) of the electroacoustic transducer is electronically processed to produce a signal indicating the flowrate.   In another embodiment the acoustic signal may be generated by elements of the fluid transmission system or by turbulent flow created upstream of the transducer (13). <IMAGE>

Title: Transference of a fluid from a container to a fluid-flow line
Inventor: SILLETT CHRISTOPHER COLIN
IPC: F04B43/12
Filed: 1984-01-20
Abstract: To reduce loss of a fluid material, which may be edible, when a container 1 and a flexible pipe 3 therefore are disconnected from a line 11 at eg. a coupling 3b, an isolating valve 4 is provided at or adjacent the connection to the said line. Preferably, the flexible pipe is not detached from the container at eg. a coupling 3a.

Filed: 1984-03-01
Abstract: A vessel intended to be pressurised comprises a hollow substantially cylindrical member (1) and a closure member (2) which extends across the cylindrical member when in position to close an end thereof. Screw-down fastenings (9) for holding the closure member on the cylindrical member in its position to close the end of the cylindrical member are disposed in a first ring (9A) around the two members and in a second ring (9B) outboard of the first ring. A seal (3) for maintaining fluid-tight closure between the members (1,2) during radial movement of the cylindrical member comprises a carrier of ring configuration carrying seal means disposed to be in contact with inner surfaces of these members (1,2) when the closure member is in position to close the end of the cylindrical member, the carrier being able to expand or contract to permit the seal means to remain so in contact during radial movement of the cylindrical member. The seal (3) is also able to slide axially of the cylindrical member and therefore the gap between the closure member and the cylindrical member may be closed as the vessel is pressurised. <IMAGE>

Patent GB-2143578-A (GB)
Title: Door catch
Inventor: POPLE LEONARD WILFRED
IPC: E05C19/04
Filed: 1984-07-19
Abstract: In order to reduce the force required to close a door against the resilient biassing of the door catch, it is arranged that the resilient biassing is only fully released, by magnetic interaction between the striker assembly and the detent assembly (2), once the door has closely reached the fully closed position. The striker assembly incorporates a magnet which draws a mild steel detent roller (7) and its non-magnetic detent body (6) from a retracted position to a projected position, allowing a cam block (18) to slide under the force of a spring (19) to bring a surface of the cam block under a projection (22) of an abutment member (20) for main spring (21) biassing the detent, thereby rendering the main spring fully operative. On opening of the door the main spring is automatically rendered inoperative again, inward displacement of the detent body providing a return movement of the cam block, allowing projection (22) to fall into recess (23) of the block to reduce the effective biassing of the main spring. <IMAGE>
