Abstract: 1,148,500. Cathode-ray tubes. M-O VALVE CO. Ltd. 22 Nov., 1967 [1 Dec., 1966], No. 53880/66. Heading H1D. In a cathode ray tube employing post-deflection acceleration and wherein the second pair of electrostatic deflecting plates 9 are screened from the acceleration field by a mesh 13 and by a pair of shield plates 17 disposed above and below the plates 9, a non-linear deflecting characteristic of the plates 9 at wide deflections is prevented by the provision of auxiliary deflecting plates 22. The auxiliary deflecting plates 22 are preferably rectangular and arranged parallel to the axis of the tube; they may be connected together internally to the mesh 13, or they may be connected together or separately to lead-in connections coupled to a potentiometer or to a source of potential which varies with the deflecting voltage applied between the plates 9. The electrodes may be supported from four glass rods 18, and the acceleration field may be provided by a spiral coating 14 on the tube envelope.

Abstract: 1380324 Heating fuel for I C engines ROBERT BOSCH GmbH 23 Nov 1972 [24 Nov 1971] 54233/72 Heading F1B An I.C. engine is supplied with fuel which is heated by electric heater 12 whose heat output depends on the pressure in the inlet manifold downstream of throttle valve 20 and the temperature of the engine. A slider 16 of variable resistor 15 responds to manifold pressure by moving towards position 1 to increase the current flow when the throttle is closed. An expansible element 30 in the cooling fluid of the engine displaces the resistor 15 upwards to reduce the current when the temperature of the cooling fluid rises. A bypass switch 32 is closed to heat the fuel before starting.

In a preferred embodiment the fluidization apparatus 4 is pulled along a concrete-coated steel pipe-line 11 by barge 21 as the pipe-line is paid out by the barge. The horse-shoe shaped yokes 7, to which the perforated metal pipes 5 are fixed, each comprise a curved metal strip 8, whose ends are linked by bolt 9 and nuts 10. Ball, roller or other antifriction bearings 12, 13 are mounted on each yoke 7 to allow the apparatus to slide along pipe-line 11. Negative buoyancy is produced by steel ballast bars 14, secured to yokes 7, and if necessary by ballasting pipeline 11. The leading yoke (15, Fig. 3, notshown), is provided with an extension (16) to which a pulling cable (20, Fig. 1, not shown) from barge 21 is attached through eye 19. The fluidization fluid, preferably water or a water-air mixture is supplied from barge (21) by means of a hose (not shown) to a distribution chamber (17) through inlet 18. Alternatively the fluidization apparatus 4 may carry pumps to suck in surrounding seawater for expulsion through nozzles 6.

Abstract: 1410671 Discharging static electricity XEROX CORP 20 Dec 1972 [30 Dec 1971] 58828/72 Heading H1X A.C. corona discharge apparatus for neutralizing an electrostatic charge on a charge-bearing surface 13 comprises an elongated corona discharge electrode 10, a shield 11 partially enveloping said electrode along a lengthwise axis thereof and coupled to a reference potential, a source 12 of alternating voltage having one terminal coupled to said electrode and another terminal coupled to said reference potential for energizing said electrode to produce a corona discharge thereat, an impedance 14 connected in series between said electrode 10 and said one terminal of said source for so controlling the relative magnitude of positive and negative peak valves of the energizing voltage as to reduce or eliminate any residual charge remaining on said charge-bearing surface and means providing a return path from said chargebearing surface to said reference potential. The impedance is preferably a resistor and is stated to increase the positive peak values of the energizing voltage so as to exceed the negative peak values thus counteracting the excess of negative ions at the surface 13 arising from the fact that a negative corona discharge is initiated at a lower threshold voltage than a positive corona discharge. In an alternative embodiment (Fig. 5, not shown) a D.C. supply is connected to the shield 11 to enable the residual charge to be reduced to zero.

Title: Apparatus including a press and a feed device for moving a  sheet of material through the press
IPC: B21D43/06
Filed: 1973-12-20
Abstract: 1448688 Feeding sheets in presses TRIDAN TOOL & MACHINE Inc 20 Dec 1973 59173/73 Heading B3W A press includes a feed device for moving sheet through the press, the device comprising first and second reciprocable feed bars each carrying a feed finger for engaging a hole in the sheet, guide means on which the bars are slidably mounted and motion converting means connected to the bars and to a platen of the press and operable to cause the bars to reciprocate in response to vertical motion of the platen, the feed finger of the first bar engaging and feeding the sheet on the downward stroke and that of the second bar on the upward stroke. As shown, Figs. 1 and 2, pivotally mounted arms connect the top platen 28 through links such as 45, 46 to two feed bars, arms 32, 39 to feed bar 35 and arms 33, 40 to feed bar 34, the feed bars being reciprocable along shafts 37, 38. On the downward stroke of the press, spring-loaded fingers 56 on feed bar 34 engage in collared holes 29 formed in the sheet 22 by dies 26 and the bar 34 is moved in the direction of arrow 49 to feed the sheet forward. The feed bar 35 is simultaneously moved in the direction of arrow 48, its fingers 56 being depressed into their housings by the sheet 22, due to their bevelled upper faces. On the upward stroke of the press, the feed bar 35 feeds while the feed bar 34 is retracted. A pressure plate 57 forces the sheet 22 down to enable the fingers to engage in the holes 29. In a further embodiment, Fig. 5 (not shown), one of the pairs of feed arms is replaced by a double acting air cylinder (109). With the piston-rod 110 retracted the cylinder operates like feed arms as in the Fig. 1 embodiment. With the piston-rod extended, no feeding takes place on the upward press stroke. In the Fig. 1 mode of operation the sheet is fed a distance equal to twice the space between adjacent holes 29 on each press cycle of down- and up-stroke. To produce a length of perforated sheet with an uneven number of holes, the cylinder is actuated when the length is one hole short of the required number so that in the next press cycle the sheet is fed only on the down stroke. A cut off is provided at the left hand side of the press, Fig. 1. Instead of the arms 32, 33 &c. and links 45, 46, the platen 28 may be connected to feed bars 158, 159 by racks 154, 157, pinions 166, 173 and cranks 164, 171, Fig. 6. One of the racks may be reciprocated by a double acting air cylinder operating similarly to that in the Fig. 5 embodiment.

Abstract: 1,210,329. Friction clutches. SOC. ANON FRANCAISE DU FERODO. 12 Dec., 1968 [15 Dec., 1967; 21 June, 1968], No. 59200/68. Heading F2C. A diaphragm clutch for use in self-propelled vehicles includes a diaphragm bearer element subject to two opposing forces, one provided by a prestressed resilient device and the other being variable as a function of the speed of a driving part of the clutch. In Fig. 1 a driving shaft M is running at idling speed and a diaphragm bearer 15 is urged away from a reaction plate 10 by prestressed springs 26. Centrifugal weights 27 are pivoted to the plate 10 and remain in the shown position so long as the shaft M does not exceed idling speed. When this speed is exceeded the weights 27 pivot to the position shown in Fig. 2, the action of the springs 26 is overcome and a friction plate 12 is engaged by a thrust plate 11 under the action of a diaphragm 16. Such action is precluded at idling speed, Fig. 1, since clips 25, 25a on the thrust plate 11 are in abutment with the diaphragm bearer 15. Above idling speed, the user, by a thrust bearing 19, 20, may control the clutch in the conventional way. Light springs 32 assist in freeing the plate 12. In a modification, Fig. 3 (not shown), the weights (27) act on the diaphragm bearer (15) by links (70). In Fig. 4 a spring washer 26b urges the diaphragm bearer 15 to the left and away from a cover 40 secured to a hub 42 fast on the driving shaft M. Above idling speed, weights 27 cause the bearer 15 to move to the right, Fig. 10 (not shown). As before, the thrust bearing 20 provides for declutching by a user.
