Abstract: 1,122,386. Transducers. STANDARD TELEPHONES & CABLES Ltd. 9 Dec., 1965 [16 Dec., 1964], No. 51168/64. Heading H4J. In a pressure sensitive transducer, more particularly a semi-conductor microphone, an overload responsive device is included in the coupling between the diaphragm and transducer element. The latter may be a diode or a transistor having an exposed or a buried junction and may be of the type described in Specification 1,027,102. As shown, the overload device may be a slipping clutch 6 having a thixotropic filler in a silicone fluid 7 as the slipping medium (Figs. 4-6, not shown). Alternatively, it may comprise an artificial fibre (or fibres) which is biased by two leaf springs so as to be non-compressible under an overload pressure (Figs. 13 and 14, not shown). Yet again it may consist of a pivoted lever having magnets, e.g. magnetic dust in a soft rubber casing, at each end which co-operate respectively with metal plates on the diaphragm and transducer element (Figs. 15, 16, not shown). Alternatively, a plastics sheet may be used to cover the element, the sheet being shrunk under heat so as to prestress the element whereafter a fibre which collapses under overload is used to transmit pressure from the diaphragm to the element (Fig. 17, not shown). In another embodiment the diaphragm itself is made of a plastics material which deforms and collapses under overload (Figs. 20-24, not shown). In yet another arrangement, a rod, restrained against non-axial movement at its ends, is connected at its centre to a diaphragm whereby small transverse movements are effectively converted into longitudinal movements of the rod and hence pressures on the element but overload causes flexure of the rod and consequent loss of contact between the end of the rod and the element (Fig. 25, not shown). A transducer of the fibre type mentioned above (Fig. 17) may be used for demodulating an A.C. signal superimposed on an ultrasonic carrier (Figs. 18, 19, not shown). The transducer may comprise two diaphragms, one carrying the coupling and the other the element and such a transducer may be used in the pressure or the pressure gradient node (Figs. 4 to 8, not shown). The transducer may act as a microphone, an accelerometer or a pressure-sensitive switch. Reference has been directed by the Comptroller to Specification 1,077,205.

In an arrangement for producing patterns including ascender and descender Alpha- Numeric characters that ascend and descend, respectively, above and below a predetermined character base line, each character is formed by a plurality of scans on an imaging device, specifically a cathode-ray display tube, the start of the scans being positioned on character scanning reference lines which are located at the lower most point of the characters. Thus, in the case of ascender characters the scanning reference line coincides with the base line whereas in the case of descender characters the reference line is located below the base. This is shown in Fig. 2, where the character base line 37 for the upper case ascender letter H coincides with the reference scanning line whereas in the case of the lower case descender letter p the character scanning reference line 39 is located below the character base line 37. All characters are formed by a series of vertical line scans the lengths and the ON-OFF conditions of the scanning beam of which are determined by binary coded information which also controls the beam to move horizontally in step-by-step manner until the full character width (see Fig. 2) has been traversed after which the beam, which is jumped from a rest position 140 at the start of the scan returns to a position below the trailing side of the letter H, and is jumped to position 146 preparatory to commencing the scan of the letter p. The operation of the system is controlled by a memory 50, Fig. 3 (also Fig. 1, not shown) divided into two portions, a primary portion 52 and a secondary portion 54. Portion 52 includes a plurality of successive locations corresponding one-to-one with the characters &c. in a type fount and may be addressed by a character code comprising, e.g. a binary number that is a coded representation of the character &c. The contents at each location comprises an address for the secondary portion 54 at which blocks of information necessary to form the character on the display tube are stored. This information, comprising the data indicated in Fig. 3 (see also Fig. 2) is then employed in a circuit (Fig. 1, not shown) utilizing logic elements to form the character on the screen of the display tube which is imaged on a photographic film.
