A rotary pump or motor of the outwardlysliding vane and multiple abutment type, comprises a rotor 1, Figs. 1 and 2 (not shown), having a plurality of radial axially-extending slots 3 slidably mounting vanes 4 formed with axial extensions 402, 403 slidably mounted in slots 302, 303 formed in side-plates 102, 103 extending radially beyond and rotatable with the rotor 1 and a stator comprising an annular member 2 located between the side-plates 102, 103 and formed with diametrically opposite recesses divided by each vane as the rotor rotates into working chambers 41, 42 and 39, 40. Operating as a motor with the rotor (Fig. 2) rotating clockwise, connections 19, 20 constitute high pressure inlets and connections 21, 22 low pressure outlets. To ensure fluidtightness between these connections and the chambers telescopic seal members 30, 32 are urged apart by springs 14 into engagement with spherical faces on support rings 27 whose opposite plane faces engage the stator 2 and outer casing member 46. Limited movement of the stator to follow any out of alignment movements of the rotor is provided for by means of dovetail-shaped pieces 13 slidable in diametrically disposed complementary shaped grooves 7 in the stator member 2 together with a radial pin 12 tighly fitting each piece 13 which has a clearance fit in a hole 9 in a floating ring 8 also provided with holes 10 at 90 degrees from the holes 9 to receive loosely fitting pins 11 which in turn are tightly fitting in the casing 46. So as not to impair the strength of the vanes 4, springs 6 fitted in recesses in the side-plates 102, 103 engage the vane extensions 402, 403 to urge the vanes outwardly. In a modification, the springs, may be replaced by pistons 68, Fig. 3, (not shown), slidable in cylinders formed in cover members 59, 60. Fluid pressure in the working chambers 39, 40, 41, 42 is communicated to the piston faces through passages 107, 63, 65 to move the pistons and hence the vanes with which they are operatively connected. The support rings 27 adjacent the working chambers and the tubular sealing members 30 are formed with annular recesses to provide .pressure surfaces on which pressure fluid acts to balance out fluid pressure forces and assist the springs 14 in urging the telescopic seal members 30, 32 apart. Instead of the stator having a pair of diametrically opposite recesses, it may have three or more equiangularly spaced.

Abstract: 1395555 Display terminal controller INTERNATIONAL BUSINESS MACHINES CORP 9 Aug 1972 [20 Aug 1971] 37126/72 Heading G4C The memory in a display terminal controller comprises a plurality of buffer memories, including a regeneration memory 18 (Fig. 3), which can receive data from and supply data to a retain memory 20 and a print memory 19 which can be fed from the regeneration memory 18. The buffer memories may receive data from a CPU via a receive buffer 17 or from a keyboard 22 and feed a cathode-ray tube display 21 or a printer 23. The memory is preferably part of a core memory having sections assigned to each terminal unit which the controller serves. All the controller functions are controlled by a micro program recorded in a read only memory. Data from the keyboard is stored in the buffer 18 and displayed on the screen at a position determined by a cursor, the cursor being controlled by the micro program to advance one position each time a new character is entered. When a protected character indicating the beginning of a protected area is encountered the cursor is advanced until an end protection is detected. When requested by the CPU data in buffer 18 is fed to the CPU starting at the first stored character and omitting characters in protected positions. Operation of a key results in display data from the keyboard or CPU being additionally printed. A particular line displayed on the C.R.T. may be selected and stored by positioning the cursor on the required line and then operating a selection key to transfer the selected data from the buffer 18 to the retain buffer 20. When a display key is pressed stored data in buffer 20 is transferred back to the buffer 18 and displayed, data stored from the keyboard being erased by this operation but data entered from the CPU being held. Data from the receive buffer 17 may be fed to buffer 18, via buffer 18 to buffer 20 and to buffer 19.

Abstract: 991,761. Colour television receivers. PHILCO CORPORATION. Oct. 18, 1961 [Oct. 20, 1960], No. 37351/61. Drawings to Specification. Heading H4F. In a colour television receiver for a signal comprising luminance and chrominance components and which has an automatic gain control system which controls the overall gain of the receiver 50 so as to compensate for variations in the strength of the received signal together with an automatic colour control system for varying the gain of an amplifier for the chrominance component inversely in accordance with the amplitude of the chrominance signal synchronizing "burst," if the automatic gain control system is of the averaging type in which the gain variation is a function not only of the signal strength but also the average brightness level of the signal, colour saturation errors are introduced since the system causes the amplitudes of the colour " bursts " to vary with brightness level and hence causes the chrominance amplifier gain to be varied inversely so that undersaturation is produced for dull scenes and oversaturation for bright scenes. In accordance with the invention, this deleterious effect is removed or reduced by employing the automatic gain control system also to control the gain of the chrominance amplifier. In a first embodiment, Fig. 2 (not shown), the control voltage from the control system which is of a known type and not described, is added to the automatic colour control voltage derived from the synchronizing " burst " and the combined voltage applied to control the chrominance amplifier. In a second embodiment, Fig. 3 (not shown), a voltage which varies with the automatic gain control voltage is derived from the screen of the video output stage and applied to vary the delay voltage in the automatic colour control system.
