Title: Acoustic imaging and image deflection systems
IPC: G01N29/00
Filed: 1973-08-17
Abstract: 1437486 Piezoelectric devices; acoustic lenses STANFORD RESEARCH INSTITUTE 17 Aug 73 [21 Sept 1972] 38977/73 Headings H4b and H4X An ultrasonic transducer arrangement converts a portion of a focused compressional acoustic image field of an area to be viewed to electrical impulses representative of the incident focused compressional acoustic image field. The electrical impulses can be used to produce an image of the area. The arrangement, which can be used in medical applications for observing an organ continuously, includes an array of piezoelectric elements arranged in a single curved line, the line being defined by the configuration of the focused compressional image field. A transducer arrangement 10 (Fig. 1) comprises a plurality of transducer assemblies 12 secured together side-by-side to an arcuate support 14. Each transducer assembly mounts a piezoelectric slab 16 constituting a linear array of piezoelectric elements and the piezoelectric slabs 16 form a curved linear array. Each slab 16 (Fig. 2) has slots 18 cut across it to provide thirty two islands 20 and an equal number of slots 18. Both sides of the slabs 16 have a silver coating 17. The slabs 16 (Fig. 8) are supported by a metal support 30 in a slot (32) Fig. 4 (not shown). Acoustic matching material consisting of 58% by weight tungsten powder, balance epoxy resin, fills the slot (32). The rear side of the metal support 30 has a printed circuit board (42, 44) with conductive fingers (46a, 47a) which are connected electrically to the silver coatings on the islands 20. Between these conductive fingers (46a, 47a) are non-contacted fingers (46, 47) which form a Faraday shield. A channel shaped member 58 of non-conductive plastics is secured by epoxy resin to the printed circuit boards (42, 44) and holds the individual assembly 12 together. An aluminium block 60 is fixed by bolts 62 to the channel shaped member 58 and the block 60 is secured to the arcuate support 14 by a bolt 64. The aluminium block 60 supports four printed circuit boards 66 each of which supports preamplifiers for amplifying signals from the piezoelectric elements. Each piezoelectric island 20 constitutes one sampling element of the curved linear array. Sampling takes place sequentially an element at a time along a single linear portion across the compressional image field. The next adjacent line portion of the compressional image field is then scanned. Each island 20 is preferably square but practical constructions are usually oblong. Such oblong islands 20 require a cylindrical collimating lens spaced from the slab 16 by a distance that permits the converging incident wave field to focus in the adjacent plane of the slab 16 along the direction parallel to the lens. The lens may be in one curved piece which fits the entire transducer arrangement 10 or may be made in segments, one segment for each transducer assembly 12 and adjacent ends of lenses being chamfered so that only one lens is effectively formed when the individual transducer assemblies 12 are put together.

Title: Improvements in or relating to Gramophones
IPC: G11B3/28
Filed: 1966-09-01
Abstract: 1,162,097. Supporting gramophone pick-ups. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 1 Sept., 1966 [4 Sept., 1965], No. 39003/66. Heading G5R. A gramophone having a turntable and a pickup arm pivotable about horizontal and vertical axes, and having means, connected between the pick-up arm and a fixed part, which exerts a force on the pick-up arm which influences the force of the stylus on a record during play and which also exerts a varying torque on the arm to counteract the torque produced by the varying transverse component of the tangential frictional force generated at the point of contact between stylus and record, is characterized in that the means are adjustable and are connected to the pick-up arm at a region such that, upon variation of the forces exerted on the arm by the means, the stylus force and the above - mentioned counteracting torque are varied in direct proportion to one another. As shown, a pick-up arm 7 journalled in a Cardan suspension having a horizontal pivot 9 and a vertical pivot 10 is balanced by an adjustable counterweight 13. A coiled tension spring 16 secured between a point 17 on the fixed outer ring 11 of the suspension and a part 18 slidable along a limb 15 provides an adjustable clockwise stylus pressure on the record. The point of attachment 17 is located slightly on the nearer side (as viewed in Fig. 2) of the ring 11, so that the spring 16 also exerts a torque which (in plan) is counterclockwise, thus forcing the stylus 12 towards the outside of the groove in the record to compensate for the radiallyinward component of needle drag. The spring may be below the pick-up arm, in which case the movable connection is to the right of the suspension, and the fixed connection is on the further side of ring 11. In a modification, instead of the spring of Fig. 2, a vertically polarized magnet, adjustable along limb 15, is attracted towards a vertically polarized magnetic member arcuate in horizontal plan and connected to ring 11: the centre of the arcuate member is eccentric with respect to the vertical pivot 10. One magnet may be replaced by a soft iron element. The magnets may repel. Electromagnets may be used, the forces being adjusted by varying the current through the coils.

Abstract: 1,240,166. Creping paper. KIMBERLYCLARKE CORP. 15 Aug., 1968 [17 Nov., 1967], No. 39049/68. Heading D1S. A paper web 28 is creped by leading the web 28 while moist around a rotating suction roll 10 so that the paper adheres to the surface thereof and doctoring the web 28 from the surface of the roll 10.

A suction box 23 is defined within the roll 10 by a wall 24 mounted on the manifold 16 on each side of the line of holes 17. Each wall 24 supports a seal 26 in contact with the inner surface of the shell 11. A stationary doctor blade 27 scrapes the web 28 from the roll 10 to produce a creped web 29.

Title: Colour television apparatus
IPC: H04N9/73
Filed: 1976-09-22
Abstract: 1523070 Colour television ROBERT BOSCH GmbH 22 Sept 1976 [27 Sept 1975] 39258/76 Addition to 1506413 Heading H4F In a modification of the apparatus disclosed in the main patent, the first means comprises apparatus detecting when the brightness is within a range adjacent the white value, the threshold of the range being varied according to the peak white value detected. As described, the luminance Y is applied to the base of transistor 2 so that capacitor 5 is charged to the level of Y less U BE , the voltage dropped across the transistor. Luminance signals less than this value are blocked since the base is then more negative than the emitter so that capacitor 5 slowly discharges through resistor 6 and so reduces the potential of the emitter. In this way only luminance above a varying threshold is output at 11. The threshold is prevented from dropping below 70% by the connection to positive potential 9 through resistor 8.
