Title: Transfer roller switching mechanism of ink and water supply apparatus for use in printing press
IPC: B41F31/14
Filed: 1981-02-10
Abstract: Apparatus for supplying ink and/or water to a plate cylinder (2) through a fountain roller (9), a further roller (10) and a transfer roller (12) which is mounted on a swinging arm (11) for swinging movement into contact alternatively with the fountain and further rollers. A swinging lever (43) which moves with the arm (11) has at its free end a projection (44). A control member (41) is moveable, e.g. by rod (48), either to engage the projection (44) to block the swinging movement of the transfer roller (12) when the rubber cylinder is disengaged from the plate cylinder or to permit such movement when the rubber cylinder is engaged, and means is provided to enable this command to be overridden. As shown, a manually operable switching disc (32) can be brought into operation when required by rotating it either to a first position in which a projection (34) thereon is moved to block the swinging movement of the lever (43) and hence of the transfer roller (12), or to a second position in which a second projection (33) thereon engages a part (41a) of the member (41) to hold it in a position in which the lever (43) is free to swing. In the latter case, the rubber cylinder can be engaged or disengaged with the plate cylinder by compression of buffer spring means (52, 53) in the connection between rod (48) and lever arm (40) of the control member (41). …<IMAGE>…

Title: Power Feeder Protection Apparatus
IPC: H02H7/26
Filed: 1981-03-18
Abstract: In a protection apparatus for a feeder (H) of an electric power transmission system compensation for mutual coupling between the feeder and another feeder (G) is controlled in dependence on the ratio of the zero sequence currents (IM, IN) in the two feeders. The mutual coupling compensation signal (IMZM%) is arranged to be proportional to the zero sequence current (IM) in the other feeder when the ratio of the zero sequence currents is below a predetermined value, and to be limited to a value proportional to the protected feeder zero sequence current (IN) when said ratio is above the predetermined value. The arrangement reduces the possibility of maloperation of the feeder protection due to faults on the other feeder. <IMAGE>

Patent GB-2082406-A (GB)
Title: Monitoring electrical cables and joints for the ingress of moisture
IPC: G01R31/02
Filed: 1981-04-22
Abstract: Two detecting conductors such as moisture detecting tape 2 with two metallic conductors laminated to an insulating substrate are secured in or to the cable and terminated in a fixed resistance 6. The terminating resistor causes a small current to flow continuously through the detection conductors and should the line open resulting in a loss of protection, the absence of the monitoring current will signal an alarm indicating a system fault. The ingress of water into the cable system will result in an increased current in the monitoring line which is then detected by the remote electronics equipment and an alarm is activated. Coded signals are used to indicate the position of a faulty splice, and to effect isolation of a selected cable portion. <IMAGE>

Title: Improvements in or relating to control systems for automatic change-over between transmission and reception of communication devices
IPC: H04R3/02
Filed: 1981-04-24
Abstract: A control system is provided for changing automatically between transmission and reception states in a two- way communication device. Output signals of an ear microphone 1 to be transmitted by a transmitter 3A are shorted by a relay 8 for a limited time immediately before the transmission state is changed to the reception state to prevent the occurrence of malfunction caused by noise signals which frequently occur when such a change- over operation is performed. <IMAGE>
Patent GB-2076895-A (GB)
Title: Pumping systems using ejectors
IPC: F04F5/42
Filed: 1981-05-07
Abstract: For pumping hot radioactive liquids ejectors are used with a supplemental vapour removal component to avoid ejector choking. In one form of the invention (Figure 1) steam from a line 5 enters the inlet 4 of an injector tangentially so as to induce rotational flow, liquid from the tank 1 being drawn into the ejector 3. The rotational flow causes the liquid to flow outwards towards an outlet 6 while any vapour collects in the centre of the ejector to be removed by an ejector 13 via pipe 12 and returned to the tank. In another form (Figure 2) an ejector 30 draws liquid from a tank 21 into a flash chamber 24 via tangential inlets, vapour separating out to be removed by an ejector 26. <IMAGE>

Patent GB-2081598-A (GB)
Title: Oil storage tank
IPC: E21B43/34
Filed: 1981-06-22
Abstract: In removal of water/saline and dissolved gases/vapours from crude oil, the crude is elevated by pipe 16 to a collector 18 with inverted weir outlet 19 and permitted to flow along a flash-release tray 20 which is at a shallow angle to the horizontal and on which degassing occurs. Cascade trays 21, 22 transfer the degassed crude to the stored oil body at a shallow angle which prevents turbulence on entry into the stored oil body. Gravitational oil/water separation occurs and the separated water is removed by draw-off 26. The crude treatment is confined to within a housing 24 with lateral apertures 25 which is vertically orientated and adjacent side wall 11 of the tank 10 diametrically disposed relative to draw-off 26. Housing 24 and trays 20, 21, 22, are carried by tank side wall 11 and floor 13 and the roof structure 12 is unloaded. <IMAGE>

Patent GB-2086609-A (GB)
Title: Objective refractor for the eye
IPC: G02B3/10
Filed: 1981-10-30
Abstract: An objective refractor for the eye E is disclosed in which knife-edge optics are utilized. The knife-edge optics cause characteristic illumination of the retina R so that components of sphere and astigmatism can be identified. Provision for remote reading of the characteristic images is provided with the result that two orthogonally disposed knife-edge images can identify the sphere, cylinder and axis required for prescriptive patterns giving the direction and magnitude of required prescriptive change. A system of at least two orthogonally disposed knife edges with weighted lighting A-D' is disclosed for detection. Utilization of the knife- edge images is made possible by the detection of the low light level images at a detector having low noise level. A Photo-sensitive element divided into a plurality of photo-discrete segments D1- D4 has light from the images proportionally dispersed over its surface. Such dispersion occurs through a matrix of wedge-shaped segments (Figure 3 not shown) or alternately in the form of optical elements having cylindrical components W. This dispersion of the light when used in combination with push-pull knife-edge patterns herein disclosed produces detectable low level refractive signal. An embodiment using an optic having a plurality of side by side optic elements, each element having the effect of crossed cylinders, is disclosed with the detector. Separate independent and non-interactive positional information on one hand, and refractive information on the other hand, is provided. Consequently the disclosed refractor is insensitive to adjustment and can accommodate a large range of pupil configuration with insensitivity to local retinal variations in light emission.

Title: Improved tool steels which contain boron and have been processed using a rapid solidification process and method
Inventor: RAY RANJAN
IPC: C22C45/02
Filed: 1982-03-02
Abstract: Alloys having compositions similar to commercial tool steels, but modified by the addition of 0.1 to 1.5 wt% boron are subjected to a rapid solidification processing (RSP) technique, producing cooling rates between 10<5>-10<7>  DEG C/sec. The asquenced RSP ribbon or powder, consists of a single phase with a body centered cubic structure. After selected heat treatments, the rapidly solidified alloys have a microstructure consisting of ultrafine metallic carbides and metallic borides dispersed in an iron rich matrix and thus have high hardness, wear resistance and high-temperature stability. These final structures have improved properties for applications, e.g., where standard high speed tool steels are now utilized.
