Title: Production of fibre reinforced materials
IPC: B29B15/12
Filed: 1969-07-25
Abstract: 1314975 Resin-fibre composites LYONS REDCLIFF MACHINERY (BRISTOL) Ltd 20 Aug 1970 [25 July 1969] 37430/69 Heading D1R A bonded fibre material is produced by projecting onto a surface a continuous length of fibrous or filamentary reinforcement coated with matrix liquid by transfer of momentum between the matrix liquid and the reniforcement. A nozzle 3 is inserted in casing 1, and pressed against end cap 2 by screw threaded locking element 4. The reinforcing filament, e.g. of glass, enters at the rear and is fed out through orifice 9 and aperture 10. Matrix liquid is fed via inlet 7, chamber 6 and channel 5 to the annular outlet 11. It impinges on the fibre with a directional force that expells it in the direction of the arrow. Blockages caused by setting of the matrix liquid can be cleared by moving locking element 4, which may be held in place by hydraulic or pneumatic means, rather than the screw-thread shown. The matrix fluid may provide the hydraulic actuation, and the locking element may be arranged to move back when a pressure limit is exceeded. Air pressure may be applied to the thread space to prevent matrix liquid moving in the reverse direction. Nozzle orifice 9 need not be circular, e.g. to accommodate a tape. More than one orifice may be provided. The pattern in which the fibre is projected onto the surface is determined by movement of the projector. The projector H, Fig. 2, may be rotated by first using the matrix liquid to turn rotor E. Alternatively an oscillatory motion may be imparted. In other embodiments the projector is moved manually, or kept stationary, the orientation of the fibre being varied, before or after it leaves the orifice 9 by means of a moving pulley, roller or fair-lead, by means of air streams. or by altering the velocity and/or volume of the matrix liquid.

Title: Method and apparatus for testing reedles musical instruments of the woodwind type made of wood plastic or metal
IPC: G10D7/03
Filed: 1970-11-05
Abstract: 1315338 Testing recorders M M SHIPP 1 Feb 1972 [5 Nov 1970] 52664/70 Heading G5J Recorders are tested by applying air at controllable pressure to the mouthpiece and comparing the frequency or waveform of the resultant sound with that from a good instrument of the same type, the difference in frequency or waveform giving a measure of the musical quality of instrument being tested. In a first method, the appropriate finger holes of a good recorder are covered to tune it one tone above its lowest note, and the pressure applied to the mouthpiece is steadily increased. At a first critical pressure the steady note begins to warble and at a second critical pressure additional overtones suddenly occur. A pressure midway between these critical pressures is then applied to test other recorders with their finger holes similarly covered. If the warbling note is produced, they are accepted but if the note is clear or has the overtones the recorder is rejected. In a second method, the pressure required to produce a clear note as determined in the first method is applied to the mouthpiece only of a good recorder and a test recorder and the test recorder is rejected unless the frequency of the sound produced agrees with the test recorder within empirically determined limits. The frequency may be measured electrically using a microphone amplifier and frequency meter.

Abstract: 1316254 Automatic alignment control SIMON-HARTLEY Ltd 9 Nov 1970 [11 Dec 1969] 60426/69 Heading G3R In a system in which a travelling structure is supported on carriages driven along the tops of parallel walls, slew as lateral displacement of the structure is sensed by rollers arranged to bear on the sides of the walls, movement of a roller relative to its carriage causing operation of a switch which controls the drive to the carriages so as to correct the movement. As described, a gantry carrying a scraper or sludge lifter spans a sludge drying bed and is supported at its ends by motor-driven carriages which run on wheels along the tops of walls on each side of the bed. In Fig. 3, lateral or skew movement of one carriage 12 relative to a wall 14 is detected by a spring-loaded feeler 20 engaging the side of the wall and operating a limit switch 27. One carriage has four such feelers, one at each corner, and, according to the condition of the associated limit switches, the drive of one carriage is automatically slowed or speeded up relative to the other as necessary to correct lateral displacement or skew due to unequal advance of the carriages. Rotation of a cam 23 as the feeler moves along the wall causes intermittent operation of switch 27 for periods proportional to the positional error. The gantry may move continuously backwards and forwards along the bed. The four feelers may be shared between the two carriages.
