These layers can be arranged having a conducting layer and the emulsion layer on each side of the support and also both layers can be on the same side with either one on top of the other. In some cases, it is desirable to include additional layers of insulating polymer which can be incorporated into the element either below, between or above any of the above mentioned layers. Example 15 describes a photographic element in which the conducting layer and barrier layer are located below the radiation-sensitive layer but on the same side of the film support. Example 16 describes a photographic element in which the conducting layer and barrier layer are located on the back of the film support, while the radiation sensitive layer is located on the front side. The semi-conductor may also be used as a conducting layer in electro-photographic materials. The conducting layer is coated on an inert support and on top of the conducting layer is a second layer containing a photo-conductor. Additional thin layers of insulating polymers may also be included which may be located below, between and on top of the conducting and photo-conducting layers. Example 17 describes an electro-photographic element in which the conducting coating serves as a conducting electrode which is essential to the functioning of the electro-photographic process when an insulating substrate e.g. a polyester film support is employed. A barrier layer of acrylonitrite/vinylidene chloride/acrylic acid terpolymer is applied over the conducting layer and then a layer of an organic photo-conductor and polyester binder.

Title: Plant for steaming and fixing dyes
IPC: D06B3/22
Filed: 1973-12-19
Abstract: 1456375 Plant for steaming and fixing dyes F CONTI 19 Dec 1973 [29 May 1973] 58954/ 73 Heading D1L For steaming and fixing dyes at high or low temperature on printed or dyed fabrics a suitable plant comprises, as shown in Fig. 1, a storage chamber 1 having an inlet 3 and outlet 4 for the fabric 5, means for dispersing the fabric in the form of suspended folds side by side and for moving them on a number of freely movable rod elements 16 along a perimental closed loop path, means for maintaining the atmosphere inside the chamber at controlled humidity and temperature conditions and means for preheating and humidifying the fabric in chamber 9 before its introduction into the zone of controlled atmospheric conditions. In the preheating chamber 9 the water film which runs down the wall 12 is evaporated by the heating elements 13 and the fabric consequently becomes heated and humidified. The fabric is pulled out of the preheating chamber by the roller 15 to which it adheres because of the suction created by the exhaust fan (40), thus a fold is created downstream of the roller 15, which becomes elongated downwards until a rod element 16 taken up by hooks 27 at the end of guide 18 comes into contact with the lower face of the fabric. The fabric is thus raised by the rod element which is released from the hooks 27 when its ends (19) have entered the guides 17. During the free rolling motion of each element 166 on the guide 17, the fabric is dragged by friction by the elements 16 in such a manner that the forward movement of the folds is accompanied by a partial sliding in the vertical direction of the fabric which thus passes through any thermal and humidity gradients in the chamber. The element 16 is transferred by the hook 31 to the highest end of the guide 18 and can thus return to the start of its path by rolling freely on it.

Abstract: 1368746 Radar simulators PLESSEY CO Ltd 13 March 1972 [18 Dec 1970] 60124/70 Heading H4D  In a radar simulation system, simulated target information in a store ST is fed to an echo generator REG which utilizes the information in radar scan bearing order and feeds it to radar display RDD a counting device being provided to determine the extent of a target. Data processor PC performs a simulating program under the control of console ECC. The processor places information relating to each target (see Fig. 2, not shown) into one location of a storage area in store ST. The store has two storage areas, one of which contains the target information for the present radar scan and the other being updated for the next scan. Radar echo generator REG interrogates the particular storage area and places into its own store target information for each bearing. Generator REG then provides target bright up pulses over line VI together with SSR information over lines SSRI and AHC for end target on that bearing. The generator also supplies display timing signals DTS and is fed with radar azimuth signals AZCS. Up to four aerials, of the same characteristics, can be simulated and are selected by switches DSS on display RDD, signals DS being passed to display drive equipment RDE to give the appropriate display. Display RDD is also provided with an SSR passive decoder PD. A permanent echo generator VM is also provided. A console CP selects MTI range, aerial characteristics (both primary and secondary aerials) and radar PRF. The device for determining the extent of the target (device HG, Fig. 3, not shown) comprises means for storing a count representative of the target's extent i.e. how many scans of the display (a scan being from the centre outwards), the target will occupy. Upon each display of a portion of the target on each scan, the count is reduced by one until it reaches zero when the target has been fully displayed.
