Filed: 1974-06-05
Abstract: 1474433 Matrix displays INTERNATIONAL BUSINESS MACHINES CORP 5 June 1974 [28 June 1973] 24815/74 Heading G5C A display system comprises a gas discharge display panel with crossed conductor arrays insulated from the gas, drive circuitry to apply write, erase and sustain potentials to the conductors and control circuitry to control the drive circuitry to apply sustain pulses to only some sites along a conductor, thereby reducing the peak current to which the drive circuitry is subjected. The control circuitry also applies conditioning pulses to the cells at different times before write and erase pulses are applied. To obtain the said sustain pulses the horizontal and vertical conductors are arranged to form groups of cells C1 ... C4 and sustain signals of different shape are applied to the groups of conductors. The waveforms are arranged such that the cells in each group are sequentially energized. Preferably cells are arranged in groups of four, and diagonally opposite cells are at zero potential whilst the other pair are respectively positively and negatively pulsed. This provides effective electrostatic shielding without the use of additional grid lines as described in Specification 1,322,770. The driving circuits are described in Specification 1,381,566. Sustain signals H0, H1, V0, V1 produce voltages C1...C4 across the four cells of the group. By applying portions of the signals H0, V1 corresponding to the state numbers shown in Fig. 9 the sustain signals of Fig. 9 are obtained.

Abstract: 957,302. Haymaking machines. C. VAN DER LELY N.V. July 18, 1960 [July 18, 1959; June 17, 1960], No. 24900/60. Heading A1F. A haymaking machine for use as a side delivery rake or a tedder comprises a frame beam 1 supported by a member 43 attached to the lift linkage of a tractor and rake wheels 2, 3, 4 mounted on the frame so that each is turnable about a horizontal axis formed by the cranked ends of the rake wheel supports 5, 6, 7 and also about vertical axes formed by pivot pins 8, 9, 10 fixed to the beam. The rake wheels are swung over the beam into the tedding position shown in dotted lines by first pivoting them about the horizontal axis formed by the cranked ends of the support and then pivoting them about the vertical pins 8, 9, 10. A spring-biased locking pin 17 (see Fig. 2) passes through lugs 15, 16 on a sleeve 11 surrounding the pivot pin 10 and engages holes 21 or 22 in a plate 20 fixed to the beam to hold the rake wheel in place. A bar 24 which may be held in two different positions by locking pin 29 supports the rake wheel resiliently against the action of two springs 33, 34 which may be tensioned by nuts 38 on the rod 30. A caster wheel 42 supports the implement and an extension beam 73 with further rake wheels may be provided. A coupling member 43 connects the implement to the lift links of a tractor and comprises a beam 46 connecting at their lower ends two upwardly inclined members 47, 48 to which the three points of the lift linkage are attached, the beam 46 terminating in a bore 60 adapted to take a pivot pin 59 of a member secured to the frame beam 1 so that the coupling member 43 can pivot through 180 degrees. A locking pin 64 holds the beam in position. Two members 65, 70 have feet which may be lowered to support the implement when not in use. In an embodiment (Fig. 4) the implement is mounted on the front of a tractor by a frame beam 81 with strengthening strut 82. The rake wheel assemblies are mounted on a beam 86 connected to the beam supported from the tractor by a parallel linkage operable by a hand lever 131 to provide height adjustment of the wheels. For tedding, the rake wheels are turned as in the previous embodiment into positions such as 95A. For swath turning the rake wheels 119, 93 can be removed from their pivot pins 126, 99 and mounted on studs 124, 125 so that they lie in positions 119B, 93B. The rake wheel supports, in this embodiment, are mounted resiliently by means of blade springs 108 which resist downward movement of the rake wheels but allow upward movement.

Title: Improvements in or relating to thermionic oscillation generators
IPC: H03B5/10
Filed: 1935-09-07
Abstract: 462,329. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and BELL, D. A. Sept. 7, 1935, No. 24970. [Class 40 (v)] An oscillation generator comprising a back-coupled valve is locked into step with a synchronizing voltage by applying that voltage to a grid situated between the anode and the backcoupled grid. As shown, the anode circuit includes a tuned circuit 2, 3 back-coupled to a coil 7 in the inner grid circuit. Synchronizing voltages are applied through a condenser 12 to the outer grid 9 which is biassed positively to a point which gives large variation of oscillatory output for small variation of voltage. When a pentode valve is used, the synchronizing voltages are applied to either the screen grid or the suppressor grid. The synchronizing voltages may be of the same frequency as the output oscillations, but preferably are a multiple or sub-multiple of the output frequency. Between the outer grid 9 and the cathode, a network may be interposed which has high impedance at the synchronizing frequency, but low impedance at the output frequency, Figs. 3 and 4 (not shown).

Title: Pressure-forming of gear wheels
IPC: B23F19/00
Filed: 1969-05-16
Abstract: 1,224,140. Rolling gears. CARL HURTH MASCHINEN-UND ZAHNRADFABRIK. 16 May, 1969 [9 July, 1968], No. 24993/69. Head-- ing B3M.  In a machine for chipless pressure-working of gears with a gear-like tool the tool and workpiece are fed into meshing engagement with their axes parallel or very slightly crossed the minimum distance between the axes being such that substantial radial pressure is generated between the gear and workpiece. The direction of feed lies in a plane parallel to the tangent plane to the pitch circles of the tool and work when fully meshed and may be perpendicular to their axes or at an angle thereto to produce relative sliding movement between the teeth. The machining operation may comprise one or more feed and return strokes or even one feed stroke only, the workpiece in this case being loaded at one side of the tool and released at the other. Depth feed may take place at the end points of the strokes or may be initiated then and continue during the strokes. A machine for carrying out the process comprises a frame 10 carrying an angularly adjustable tool head 100 with pressure-working tool 12 driven from a motor 14. A vertically adjustable support 18 mounted on slideways 17 carries an angularly adjustable table 28a on which there is mounted a slide 29, feed movement of which provides feed of the workpiece 38 and is derived from a motor 32 through suitable gearing. A further angularly adjustable member comprising base 104 is mounted on the slide 29 and supports a workpiece table 116 which is pivoted to the base 104 and 115, stocks 36, 37 operable, e.g. by pneumatic, hydraulic or electrical means being provided for gripping the work. Dogs 34 on the slide 29 co-operate with switches 35 to control the reversal of the feed and the increments of depth feed. Depth feed is effected by a motor 24 through a nut 21 mounted in the support 18 and threaded on a stationary screw 19 projecting upwardly from a base 20 of the machine frame. The pivotal mounting of the workpiece table 116 allows for the tool or workpiece to be of conical form while the angular adjustments of table 28a and base 104 allow for angular feed while ensuring that the teeth are in proper alignment. The tool may be convexly or concavely crowned (Figs. 5, 6, not shown). The tool may be provided with grooves 63 in the flanks 61 of the teeth the grooves of successive teeth being aligned or staggered so as to lie on helical lines about the tool periphery. The edges formed between the flanks and groove walls are rounded or blunt so that chips or shavings are not removed, the machining action depending largely upon the pressure generated at the tooth flanks to compact the surface of the teeth of the workpiece.
