Abstract: 757,070. Gramophone pick-ups. TECHNICAL CERAMICS, Ltd. Feb. 12, 1952 [Feb. 21, 1951], No. 3747/52. Class 40 (4). [Also in Group XXXVIII] In a piezo-electric pick-up in which a stylus arm carries oppositely directed styli and is axially rotatable through 180 degrees so that either stylus may be brought into an operative position, the stylus in use is inclined against the direction of rotation of the record instead of having an inclined position in the usual trailing direction. The piezo-electric element and the stylus arm may form a rotatable assembly, Figs. 1 to 9, or the stylus arm only may rotate, Figs. 10 to 13, the element being located in a fixed position. As shown in Figs. 6 and 8, a flexible stylus arm 52 carries oppositely directed styli 21 and is attached by insulating cement at a U-connection 51 to a metallic strip 32 which has piezo-electric strips 31 of ceramic titanate attached to both faces. The titanate strips have surface electrodes formed of a fused film of silver-glass frit and are attached to the metallic strip by solder to form a piezo-electric element which is located by elastomer pads 33 between two metal casing portions 35. The metallic strip is clamped at one end by insulated hollow rivets 41, 42 between metallic terminal strips 46, spring contacts 47 and insulated spacers 43, the spring contacts providing electrical connection between the terminals and the piezo-electric strips. The casing portions are secured together by bent-over tags 36 and have tapering extensions 54 which terminate in stylus guards 55 so that the flexible stylus arm is protected from damage by excess pressure. The assembly constitutes a replaceable cartridge unit 40 which is inserted in a cylindrical metal sleeve 63, Fig. 4. The sleeve and cartridge are rotatable within a spring clip 66 which is attached to a pick-up arm 15, Fig. 1, by a bracket 61, a finger grip pin 75 being provided. This rotary movement is restricted to an arc of 180 degrees by a movement restricting slot 72 and a co-operating pin 71. A spring 80 biases the pin 71 at the extremities of movement and in these positions the styli are correctly located. In the second embodiment a similar piezo-electric element 215, Fig. 13, is secured within casing portions 211 and carries a drive extension 217 on its projecting forward end. A flexible stylus arm 221, Fig. 10, formed of metal strip or tubing passes through an opening in the drive extension and has the end remote from the styli provided with a rotary guide sleeve 231. The drive extension transmits lateral stylus movements to the piezo electric element. The sleeve is supported in a rotary guide structure 240, Fig. 12, which is secured to casing screws 213, and has projections 246 which restrict the rotary stylus arm movement imparted by a finger grip pin 235 to an arc of 180 degrees. Movement of the grip pin and stylus arm may be biased by a spring 252. Specifications 661,168 and 664,493, [Group XL (b)], are referred to.

Abstract: 1,092,531. Ultrasonic liquid-presence detector. BRITISH PETROLEUM CO. Ltd. Nov. 19, 1964 [Jan. 30, 1964], No. 3967/64. Heading H4D. An ultrasonic liquid-presence detector comprises a probe including an electro-acoustic transmitting/receiving transducer coupled to an ultrasonic wave-conducting member, and a reflector plate spaced from the member to define a space which when filled with liquid allows ultrasonic waves to be conveyed to the reflector plate and reflected therefrom, and circuitry for detecting received signals indicative of such reflection. In the embodiment of Fig. 1 Prov., piezoelectric transducer 4 is coupled to frustoconical aluminium member 3 whose base surface 5 is spaced from reflector plate 6 to define the space 8. A 200 c/s. P.R.F. generator triggers the transmission of pulses by transducer 4 and amplified echoes received from surface 5 (and from plate 6 if liquid is present in space 8) are passed through a linear stage (in which they retain their relative amplitudes) and a non-linear stage (from which all output pulses have the same amplitude) to a " metal " gate circuit and " liquid " gate circuit respectively. By means of delayed gating pulses these gates are opened only during the expected arrival time of echoes from surface 5 and reflector plate 6 respectively. For monitoring the operation of the apparatus, artificial " liquid pulses " are generated in alternate acoustic pulse transmission periods and mixed with the echo pulses applied to the linear and non-linear stages. A circuit alarm gate coupled to the outputs of the " liquid " and " metal " gates then triggers an alarm if any echo or artificial signal does not occur or occurs at the wrong time. The output of the " liquid " gate is also coupled to an " overflow " gate for actuating an alarm indicating the filling of a tank (in which the probe is inserted) to a desired level and for reducing or shutting-off the feed of liquid to the tank.
