Abstract: 1404727 Underwater tranducers BENDIX CORP 2 Nov 1973 [4 Dec 1972] 51029/73 Heading H4J An underwater transducer for transmitting and receiving acoustic spignals comprises a cylinder container 14 housing electronic equipment (not shown) and a plurality of groups of hydrophones 16 in spaced relationship therewith, each group being in an annular array (Fig. 3). A plurality of annular transmitters 10 (see also Fig. 1) is also positioned around the outside of the container 14 in spaced relation therewith. Each annular transmitter 10 comprises a plurality of segments 10a of active piezoelectric material and alternate inactive segments 10b wherein sound is projected at a different velocity than in the active piezoelectric material. The segments 10a, 10b are bonded together and electrodes are formed on the bonded surfaces of the active segments 10a. Preferably the segments 10a, 10b are cemented together using epoxy cement. Segments 10a are of barium titanate, while segments 10b are of alumina beryllium oxide, inactive lead zirconate, or aluminium. Polarization is as shown in Fig. 1. By the use of material having higher sound velocity in segments 10b than in segments 10a, a transmitter may be made of a desired resonant frequency but of substantially greater diameter than if all segments 10a, 10b were of the active material of segments 10a. To reduce the diameter, segments 10b are of material having a lower sound velocity than the segments 10a. Each transmitter 10 is preferably covered with a layer of glass epoxy (not shown) to increase tensile strength and thus power capability. Hydrophones 16 are carried in annular spacers 18 having shoulders 20 which support and position the transmitter 10. Transmitters 10 overlie chambers 22 containing oil. The spacers 18 and an acoustically transparent sheath 24 covering the transmitters and receivers are of neoprene. The container may contain a power suply for the apparatus, or all or part of it may be in a vehicle from which the apparatus is suspended.

Patent GB-526934-A (GB)
IPC: G03C7/14
Abstract: 526,934. Colour photography. LASSUS, ST. GENIES, A. H. J. DE. March 29, 1939, No. 9881. Convention date, May 24, 1938. Addition to 511,804. [Class 98 (ii)] In a method of obtaining a lenticular colour film according to the parent Specification, comprising superposed emulsions in which colour separation images are produced by exposures through the lenticulations and the primary monochrome images, a plurality of emulsions for the colour images are applied after development and fixing of the primary monochrome image in the single emulsion of an ordinary lenticular film ; the partial primary images are then each reproduced in one of the additional layers by a partial illumination through the lenticulations and the primary image, followed by development and colouring of the images in the added layers. In an example, three colour separation emulsions are employed, one or two of which may comprise silver chloride or chloro-bromide. When one chloride emulsion is employed, it may be at either side of or between two bromide emulsions. The emulsions are sensitized to different bands of the spectrum and are exposed by corresponding lights to form in each an image corresponding to one of the three primary monochrome images. If the chloride layer is the outer or second layer these two layers are first exposed and the chloride layer is developed with a colour developer which does not affect the bromide layer, which is developed subsequently. The other bromide layer is then exposed and developed. If the chloride layer is innermost, the outer bromide layer is first exposed and developed, and then the remaining layers are both exposed and selectively developed as in the first case. An example is also given of the use of two chloride or chlorobromide layers and one bromide layer, the latter being innermost. The outer chloride layer is first exposed and colour developed, and then the second, the two images being fixed with ammonia. The innermost or bromide layer is then exposed and developed, after which the silver images and remaining halides are dissolved out from all the emulsions. The primary monochrome images may be negatives or positives, the images in the colour layers being in the latter case subjected to reversal treatment. A sound track may be produced in the emulsion layer of the original film prior to the addition of the colour emulsions, which may not extend over it, and the track may be protected by a varnish layer from being dissolved with the silver images. Alternatively, the sound track record may be printed in one or more of the colour emulsions, either from a primary image in the first emulsion which is subsequently removed with the other silver images, or from another record. Specification 511,462 also is referred to.

Abstract: 1,115,266. Automatic exchange systems. WESTERN ELECTRIC CO. Inc. 17 Dec., 1965 [29 Dec., 1964], No.53610/65. Heading H4K. In a T.D.M. exchange having a plurality of concentrators associated therewith, an interconcentrator connection is set up via a non- blocking switching network located in the exchange. A non-blocking network is a network in which it is always possible to establish a connection from an idle inlet to an idle outlet regardless of the number of calls served by the network. Rearrangements of existing connections are not necessary. The network consists of cross-point matrices and delay devices, e.g. delay lines or shift registers. Three different forms of non-blocking space division networks are depicted in Figs. 11-13 (not shown), and their time division equivalents are described. The general operation of the exchange is more fully described in Specifications 922,798 and 921;384. P.C.M. isutilized and, within the exchange, either serial or parallel coding may be handled. First embodiment (Fig. 4).-The equivalent space division network consists of three stages containing respectively n, 2r - 1 and n matrices, of respective configuration r x (2r - n x x n, (2r - 1) x r. The T.D.M. network consists of an input cross-point matrix 404 to the inlets of which the send highways 104S from the various concentrators are connected; an output matrix 405 to the outlets of which the receive highways 104R are connected; and a plurality of, e.g. pulse shifters 401 interconnectng the outlets and inlets of the respective matrices. The pulse shifters (Fig. 5, not shown) delay signals received in e.g. time slot 3 on highway 104a whereby they may be transmitted during e.g. time slot 11 on highway 104b. The cross-points 404 and 405 are operated during the relevant time slots under the control of circulating delay lines 406 &c. Second embodiment (Figs. 6-8, not shown).- The equivalent space division network (Fig. 12, not shown) comprises three stages of r, n x 2n; 2n, r x r; and r, 2n x n matrices respectively, wherein each outlet from the first and each inlet to the third stage is connected to two different matrices of the second stage. The T.D.M. network consists of a single cross-point matrix which interconnects pulse shifters (shift registers) located in each of the send and each of the receive highways, there being two physical links in respect of each pair of send and receive pulse shifters. Both links of a pair may be used simultaneously, i.e. during the same time slot for different communications. Third embodiment (Figs. 9, 10, not shown).- The space division network comprises r, n x 2n; 2n, r x r; and r, 2nxn matrices. The T.D.M. network is similar to that of the second embodiment in that each highway has a pulse shifter in its receive and in its send leads but in this case there are twice as many time slots available in the interconnecting matrix as there are on any one of the highways. The pulse shifters utilize noduls (n) gates for transposing the time slots.
