Title: Improvements relating to seat assemblies
IPC: B60N2/52
Filed: 1964-08-04
Abstract: 1,082,314 Resiliently mounted adjustable seats. MASSEY-FERGUSON Inc. Aug. 4, 1964 [Aug. 1, 1963], No. 30470/64. Addition to 1,054,368. Headings A4J and A4U. A seat assembly similar to that in parent Specification 1,054,368 is vertically adjustable relative to a base 12 by means of a fluid pressure operated jack 46 to which oil is delivered from a sump (72) via a pump (76), a manually operable selector valve 58 (see Div. F2) and a conduit (82) with a restriction (83). An accumulator, which is also connected to the conduit 82 between the restriction (83) and selector valve 58, responds to changes in the oil in the jack 46 and thus resiliently mounts the seat on the base 12. Parallel links 28, 30 guide the frame member 14 in its vertical movement and a torsion bar 42 prevents twisting or tilting. The seat frame 16 is mounted for horizontal movement on tracks 66 and may be locked in its adjusted position by a latch mechanism or the seat may be moved by a double acting fluid pressure operated jack.
Patent GB-445485-A (GB)
Title: Improvements in or relating to television transmitting apparatus
IPC: H01J29/43
Filed: 1934-10-24
Abstract: 445,485. Cathode-ray tubes. McGEE, J. D., 9, King's Avenue, Ealing, and FREEMAN, G. S. P., 16, Sutton Court Road, Chiswick, both in London. Oct. 24, 1934, No. 30548. [Class 39 (i)] The conductive signal plate capacitively associated with the mutually insulated mosaic elements of a cathode-ray tube for television transmission is enclosed between two plates of mica or other material impervious to electrons or ions or soft X-rays formed within the tube, spurious signals due to such electrons &c. reaching the signal plate being thus avoided. One mica sheet 7 forms an insulating layer between the mosaic 6 and the signal plate 8 and the other mica sheet 11 supports the whole screen and keeps it flat. The screen is initially rolled up or bent for introduction into the tube 1 through the wide, short neck 3. The plate 11 extends to the wall of the tube 1 and is supported by springs 9 distributed around its edge. The sheet 7 is held to the sheet 11 by mica strips 18 and rivets 19 and is scanned by the ray developed by an electron gun in a neck 2, a coating 4 forming the second anode of the gun. To avoid deterioration of the insulation between the individual mosaic elements due to the presence of excess of caesium &c. used in photosensitizing them, the back of the sheet 11 is also provided with a silver mosaic 20, and, after the mosaics 6, 20 have been oxidized by introducing oxygen into the tube 1 and ozonizing it by a high-frequency field, the oxygen is removed and caesium is introduced through a tube 21 directed as shown so that the caesium vapour goes towards the walls 1 and is scattered back to the screen 6. The tube is baked between successive introductions of caesium and, when the tube is sealed off, the mosaic 20 is not saturated with caesium and later takes up any excess of caesium in the tube. In a modification, the mosaic 20 is omitted and the sheet 7 is held on the sheet 11 by a surrounding mica frame coated with an electrically continuous layer. The Provisional Specification describes also arrangements in which discontinuities at the edge of the screen 6 are avoided by sur. rounding the screen 6 by a mosaic extending to the wall of the tube and preferably applied to the mica frame.

Abstract: 917,720. Semi-conductor devices. SEMICONDUCTOR THERMOELEMENTS Ltd. Nov. 24, 1960 [Sept. 8, 1959],No. 30642/59. Class 37. A thermopile is made by spacing a number of P- and N-type elements in a block of electricallyinsulating material, slicing the block into sections perpendicular to the length of the elements and appropriately connecting the ends. In the arrangement shown, P- and N-type semi-conductor rods 1, 2 are located parallel to each other and spaced apart in a block 3 of electrically insulating material either by assembling them in a jig and potting them in resin or by coating them with adhesive and inserting them in a preformed block of insulating material. The block is then sliced by parallel cuts 4, the exposed ends of the rods are coated with solder, e.g. by ultrasonic soldering, or plated with nickel and pretinned aluminium plates 5, 6 soldered to the exposed ends. These plates are then slotted as shown by the dotted lines so that all the elements are series-connected PNPN between terminals 7, 8. In an alternative arrangement the end plates may be made by holding aluminium rods in a jig, potting them in a resin and slicing them parallel to the axis so that each slice forms a complete end connection. In the arrangement of Figs. 3a, 3b (not shown), the thermo-electric elements are mounted in the walls and parallel to the axis of a cylindrical tube of insulating material. Annular metal plates are then attached to opposite ends of the tube and slotted so as to leave the elements connected in series. Cooling fins are attached to the connecting plates.

Title: Controlling actuators for adjusting elements
IPC: B41F31/04
Filed: 1974-07-11
Abstract: 1474166 Automatic control HARRIS CORP 11 July 1974 [13 July 1973] 30842/74 Heading G3N [Also in Division G4] Apparatus for remotely controlling a plurality of actuators for adjusting elements each of which is controlled by an actuator comprises data means for establishing data on a fixed cycle basis and providing established data associated with each of said actuators respectively indicating movement or no movement of each of said actuators for a given cycle, and means coupled to said data means for producing a predetermined substantially fixed increment of movement for each actuator during a given cycle where the established data indicates that the actuator is to be moved during the given cycle and no movement for other actuators, whereby actuators are adjusted an amount greater than the predetermined increment in response to successive establishments of the data commanding movement. A printing press (e.g. lithographic offset) has 8 substations each for the control of the rate of flow of ink from a respective ink formation by means of 64 keys which can be driven in or out by respective actuators (motors). Each substation has a 128-bit shift register with 2 bit positions for each actuator (motor) for controlling in and out movement of the key respectively by gating. A.C. power to the appropriate input of the motor via a respective triac. Clockpulses from a central  station are gated to the shift input of each register in turn under control of an address bus to load each register from a common data line from the central station. The address bus carries the 3 most significant bits of a 10-bit binary master counter at the central station, the counter being driven by the clockpulses. The 7 least significant bits of the count control a 128-position scanner scanning manual control switches to feed the data line, and the least significant bit is passed to the data line in true or inverse form if an all-in-all-out switch is in its all in or all out position respectively (it also has an off position). The outputs of the scanner and all-in-all-out switch which are ORed on to the data line, are blocked from the data line unless the 3 most significant bits of the master counter agree with substation selection pushbuttons. A computer can supply the data line for all the substations in turn, via a series of stores for serializing the data under control of the master counter. The complete set of data is sent repeatedly a predetermined number of times, e.g. 12, before being changed, so that ink key movement of the required magnitude is built up. The computer may be responsive to position feedback from potentiometer at the press.

Title: Improvements in or relating to Thermally Conductive Metal Heat-Exchange Walls
Inventor: KUN LESLIE CHARLES
IPC: F28F1/12
Filed: 1967-07-05
Abstract: 1,195,383. Heat exchange surfaces. UNION CARBIDE CORP. 5 July, 1967, No. 30852/67. Heading F4S. A thermally conductive metal wall for transferring heat from one side thereof to a boiling liquid on the other side, is formed on the boiling liquid contacted side with a plurality of grooves spaced at a density of more than 20 grooves per inch and separated from one another by intervening ridges, and a restricted outlet from each groove to the wall surface is provided by deforming the ridge on at least one side of and along at least a portion of the length of said groove to narrow the outlet from the groove cavity to the wall surface. The surface is intended for nucleate boiling and in use it is said that vapour bubbles permanently trapped within the groove cavities serve continuously as nuclei for the formation of vapour, a thin liquid layer being maintained between a trapped vapour bubble and the adjacent metal surface, the liquid film being replenished through subsurface openings provided by transverse grooves to sustain the growth of the entrapped vapour bubbles as the vapour escapes from the groove cavities to the wall surface. The groove density will depend upon the nature of the boiling liquid, densities of 140- 200 grooves per inch being mentioned for liquids such as liquid oxygen or liquid nitrogen, whilst a density of 20-200 is preferred for water. The restricted outlets from the grooves may be formed in one set of grooves by cutting another set of grooves transvese to those of the first set and of the same or lesser depth, thereby displacing the entire ridges (Fig. 3) or the outermost portions thereof (Fig. 4) of the grooves of the first set and hence forming the restricted outlets from these grooves. The first set of grooves may be inclined to the perpendicular. Other forms are described in which the boiling- surface comprises only grooves all running in the same direction. In this case the grooves are cut singly by a scoring tool which forces the ridge being formed, into the preceding completed groove (Fig. 6) to provide the restricted groove outlets. In another single-direction groove surface described, the scoring tool is inclined to the perpendicular to produce inclined grooves.
