Patent GB-1297093-A (GB)
IPC: H04R1/08
Filed: 1971-04-23
Abstract: 1297093 Earshell containing microphone STANDARD TELEPHONES & CABLES Ltd 23 April 1971 11017/71 Heading H4J An earshell comprises an outer polyurethane body 10 which forms a segment of a sphere less than a hemisphere and which contains an acoustically transparent membrane 14 that supports a pressure gradient microphone 30 which is responsive to sound energy in the ear canal 23 caused by the passage of sound through the user's head. The interior of the shell is partly filled with polyether foam that is bounded by a further hard polyurethane inner member 13 which assist in attenuating sound impinging externally on the shell. A cushion ring 11 filled with liquid or foam plastic seals the shell to the head 20 around the external ear 21. The membrane 14 is made of nylon crepe so that even if a user's ear should touch it it will not stretch and thus not cause the microphone to resonate thereon. It also divides the shell in to two compartments. The microphone consists of a hollow cylinder whose length is equal to its diameter. The cylinder is apertured on opposite sides at 31 so as to provide access to the two compartments (to allow pressure gradient operation) and contains a taut 100 mesh nylon gauze. A piezo electric transducer 32 consisting of a lead zirconate titanate disc having gold, nichrome or silver electrodes evaporated thereon and polarized by the application of a voltage of 25 KV per cm. through the disc to the electrodes is mounted centrally of the gauze. A similar size disc of aluminium, brass or nickeliron is bonded by epoxy resin to the piezo disc. The microphone boosts frequencies below 5 KHz-these already having been subject to less attenuation than the higher frequencies during passage through the head. The output of the microphone is applied to an amplifier 16 having a large bass taper.

Abstract: 1301559 Purging paint-spraying equipment CARRIER ENG CO Ltd 14 June 1971 [29 July 1970] 36783/70 Headings F2N and F2V [Also in Division F1] In paint-spraying equipment wherein spray guns 32, 33, Fig. 1, may be selectively connected via line 31 and rotatable arm 25 to any one of paint supply ports 4, 5, 6, ... 21 or to a solvent supply port 22, from which solvent for purging the equipment is deliverable to the guns between disconnection of arm 25 from one paint supply port and connection of the arm to another-port, supplying paint of a different colour, the solvent delivery line 57, 59 to port 22 includes a piston 51/cylinder 50 combination, Figs. 1 and 2 arranged to control the pressure of the solvent, such that when arm 25 is connected to port 22 residual paint, left in arm 25 and line 31 after disconnection from one paint supply port, is discharged from the guns by the following pressurized solvent at the same rate as it was discharged before disconnection from the paint supply port. In use, with valve 59a closed, valve 60 is opened to fill solvent chamber 55, urging the piston 51 up against adjustable stop 53, valve 60 then being re-closed. A valve 61 is then opened to admit compressed air through passages 67, 68 to the space 54 above the piston. The pressure of this compressed air is equal to the pressure of the paint supply. Valve 61 is then re-closed. Arm 25 is then moved from the paint supply port to port 22 and valve 59a is opened so that the air pressure in space 54 pressurizes the solvent which passes to the spray guns. As the proportion of relatively high viscosity residual paint to relatively low viscosity solvent in the discharge line decreases, so does the combined resistance to flow of the two fluids. The position of stop 53 is adjusted in accordance with the dimensions of the paint circuit, from the ports to the discharge nozzles of the guns; this and the decreasing pressure in space 54 maintains the desired constant rate of discharge. Selector valve.-1, Fig. 1, includes a flat annulus, indicated by broken lines 29, rotatable with the arm 25 and arranged to cooperate with sealing faces of all the ports 4-23 save that port with which the end of arm 25 co-operates. The arm is mounted on a pinion 26 associated with a rack 27.

Abstract: 1322171 Reciprocating conveyers ASSOCIATED ENG Ltd 11 Sept 1970 [13 June 1969] 30214/69 Heading B8A Apparatus for transferring piston rings 13 from a receiving station A to stations B, C, comprises L-shaped arms 3 pivotally mounted on a longitudinally reciprocable beam 5. Each arm 3 is normally spring urged upwardly such that an abutment 12 projects through a slot 2 extending longitudinally of a table 1 for supporting the rings 13. Associated with the arm 3 is a stop 16 carried by the table for causing the arm to be pivoted clear of a ring 13. The beam 5 is moved by a pneumatic piston-cylinder mechanism 7. Movement of the beam 5 to the right in the figure causes each ring 13 to be moved from one station to the next, each arm 3 then pivoting clear of its associated ring. This movement of the arm also causes a spring-pressed plunger (14) Fig. 3 (not shown) to latch behind the arm to lock it in the pivoted position. Upon restoring the beam 5 to its original position, the plungers (14) are released by engagement with cam blocks 15 and the arms 3 return to their ring- engaging positions.
