Patent FI-991007-A (FI)
Inventor: EROMAEKI MARKO
IPC: H04M1/724
Filed: 1999-05-03
Abstract: A portable electronic device, which has a slidingly attached touch screen (DPL1) and a sliding lid (SL1) also slidingly installed on top of the touch screen. A keyboard (KB1) is installed on top of the sliding lid. In a normal state, the display of the device is partly covered by the sliding lid and, thus, protected by the sliding lid against mechanical stress. When necessary, the display can be revealed by moving the sliding lid away from the display, whereupon a cogging (R1) made on the bottom of the sliding lid rotates a cogwheel (CW1), attached inside the device, that touches the cogging. The cogwheel transmits the movement of the sliding lid to a movement that is opposite to that of the sliding lid of the display, through a gear rack R2 attached to the display. Correspondingly, the device can again be brought to the normal state by moving the sliding lid back on top of the display or the display to underneath the sliding lid, whereupon the cogged surfaces that touch against each other cause the remaining moving element to move, and again bring the device to the normal state. <IMAGE>

Filed: 1969-01-07
Abstract: 1,206,731. Valves. MOOG Inc. 7 Jan., 1969 [11 Jan., 1968], No. 1058/69. Heading F2V. A valve usable on an aero-space vehicle to control flow of propellent gas to a pail of oppositely - directed tangential roll - control nozzles has a vane 56 clamped to the end of a shaft 53 and co-operable with nozzle seats 49 to control gas flow from chamber 44 to nozzles 12, 13. Shaft 53 extends through torsion tube 66 and carries a radial arm 55 whose end 112 lies between heads 108, 105 on rods 91, 95 connected to the armatures 90, 94 of solenoids 86, 92. Heavy and light springs 106, 111 bias the vane to a central position when both solenoids are deenergized. Energization of either solenoid causes the vane to close that nozzle opposite the energized solenoid. The total available exit area from chamber 44 remains constant regardless of the vane position. A transducer 101 indicates the valve position. The torsion tube stiffness is chosen to match the expected Bernoulli forces tending to accelerate closure of that nozzle being closed. Electron beam welding secures the tube to the shaft at 69 and the shaft to arm 55. Restrictive orifices can be located in the nozzles or in the duct leading to chamber 44.

Title: Improvements in or relating to noise suppressing circuits for radio receiving and other signal channels
Inventor: TATE CLIFFORD EDWARD
IPC: H03G3/26
Filed: 1956-01-13
Abstract: 800,784. Radio receiving circuits; muting. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 8, 1956 [Jan. 13, 1956]. No. 1221/56. Class 40 (5). The outputs of narrow-band filters fed with radio-frequency signals and noise, and of a wideband filter fed with the same signals and noise are compared, and thereby control a muting arrangement in which the signal channel is changed from the disabled to the operative condition dependent upon the ratio of useful signal to noise. In the embodiment described, I.F. signals are applied to a detector 3, the detected signal being applied to the utilization circuits through relay contacts A1. A tap 7 on the I.F. transformer 2 is connected by coaxial cable 8 and transformer 9 to the control grid of a variable-Á amplifier valve 10, to receive the R.F. components of the signals and noise, and is subject to A.G.C. in dependence on the D.C. component thereof over resistance 12. The anode circuit of valve 10 includes the narrowband tuned transformers 13-18 each selective to an adjacent fraction of the total pass-band of transformer 2, whose primary circuits are connected in series, and whose secondary circuits each include a rectifier 19-24 connected to a common circuit including resistance 25. This output circuit is connected to the grid of valve 29 which with valve 30 forms a " long-tailed pair " circuit in the anode circuits of which is a two-coil differential relay A. In operation the potentiometer 27 is so adjusted that in the absence of signals the noise output of all the rectifiers 19-24 is the same and the grid voltage of valve 29 remains constant, relay A being unoperated, and the audio utilization channel s muted. A signal increases the output from one or more of the narrow-band filters, and sufficient voltage is applied to the grid of valve 29 to overcome: the bias from the tap 26, thus operating the relay A, and contacts A1.

Abstract: 1498760 Orienting articles on conveyers K M ALLEN 13 Jan 1976 [14 Jan 1975] 01270/76 Heading B8A Tapered articles 12, such as ears of corn, which leave a hopper 10 and travel along a conveyer 20 in series, are oriented by orienting means such that each article passes to a second conveyer 38 with its smaller end first, articles which are correctly oriented on conveyer 20 not being affected by the orienting means. The latter comprises a feeler arm 26 pivotally mounted on a shaft (68), Fig. 1 (not shown), which is connected to a magnet rod 72 of a voltage-generating transducer 28, and if the article approaching the arm 26 is smaller-end first it pivots the arm 26 slowly so that the transducer 28 produces a small voltage which does not actuate the circuit of Fig. 7, but if the article approaching arm 26 is large-end first it pivots arm 26 faster so that the resultant voltage is large enough to trigger that circuit. The said circuit comprises a transistor filter circuit 110 which allows the higher voltage to actuate an "and" gate 111 as well as a multivibrator 113 and an "and" gate 115, whereby when the article actuates a limit switch 37 a second multivibator 117 is actuated which in turn actuates the solenoid 119 of a valve 32, the latter thereby exhausting a pnuematic cylinder 33 so that an idler disc 34, which is connected to the piston-rod of that cylinder, is pushed by a spring 92 towards a driven disc 36 so that the article is gripped between those discs 34, 36, and due to the rotation of the disc 36 the article along with the disc 34 is rotated so that the article drops, small-end first, on to a shoot 39 located above the second conveyer 38, the duration of the pulse of the multivibrator 117 being such that the disc 34 is retracted when the article has been turned sufficiently by the discs 34, 36. In a second embodiment, the idler disc (234), Fig. 9 (not shown), is mounted on a spring arm (295) which is maintained in a retracted position by a pneumatic cylinder (233), and when a large-end first article actuates the pivotal feeder arm (226) the elctrical circuit of Fig. 17 (not shown) actuates the pneumatic circuit of Fig. 16 (not shown), for a duration sufficient to permit the cylinder (233) to be exhausted so that the disc (234) is pushed by arm (295) towards a driven disc (236) to grip and rotate the article therebetween.

Patent GB-395707-A (GB)
Title: Improvements in the manufacture of cellulose derivatives
IPC: C08B3/28
Filed: 1932-01-18
Abstract: Cellulose organic derivatives are precipitated from solutions by incorporating with the solution a precipitant in an amount which is a substantial proportion of that required to effect permanent precipitation but is insufficient to cause such precipitation, and then mechanically mixing the solution with a further quantity of precipitant so as to precipitate the cellulose derivative in finely divided form.  The process is applicable to the precipitation of cellulose acetate and other cellulose esters, of methyl cellulose and other cellulose ethers, of mixed cellulose esters or ethers, and of cellulose ether-esters.  The cellulose derivative may be precipitated from its esterification or etherification solution.  Cellulose esters may be subjected to ripening before being precipitated.  The proportion of precipitant added in the first stage of the process may be from a half to an amount just short of that required to produce permanent precipitation.  To ensure efficient distribution of the precipitant and to avoid local precipitation during the first stage spraying and stirring devices are employed.  During the second stage the cellulosic solution is run into the bulk of the precipitant or vice versa and is accompanied by mechanical mixing. p  The two stages may be carried out continuously.  A mixing jet may be employed in the first stage and it may consist of a cylindrical vessel containing one of the liquids and communicating by small holes with a surrounding annular space containing the other liquid.  The two liquids become mixed in the annular space and pass to the secondary precipitating bath.  In an example cellulose acetate in its esterification solution containing acetic anhydride, acetic acid, and sulphuric acid is ripened and after neutralizing the mineral acid, a large quantity of aqueous acetic acid is added with constant agitation.  The solution is then mixed with excess of aqueous acetic acid with stirring, and the cellulose acetate is precipitated in a finely divided condition. The products may be used for the manufacture of artificial silk, plastic, and other compositions.
