Title: Improvements in or relating to electrical precipitating apparatus for purifying air
IPC: B03C3/12
Filed: 1936-09-08
Abstract: 475,443. Electrical precipitation apparatus. WESTINGHOUSE ELECTRIC & MANUFACTURING CO. Sept. 8, 1936, No. 24488. Convention date, Oct. 15, 1935. [Class 39 (i)] Apparatus for electrically purifying air with the minimum production of ozone comprises an ionizing chamber 4, Fig. 8, and a precipitating chamber 5 through which the air flows in succession, the ionizing chamber comprising one or more insulated fine wires 7 spaced between relatively large electrodes 8, and means for unidirectionally charging the wires relatively to the electrodes. The wires 7 and electrodes 8 are disposed in a plane transverse to the flow of the air. Preferably the electrodes 8 are of cylindrical shape, and the unidirectional charge on the wires is positive. The precipitating chamber contains two sets of alternately disposed plates 19, 20 closely spaced; one set 19 being earthed through the casing and the other set 20 being insulated and unidirectionally charged. In the construction described the plates are built up into units and are slid into position in the casing in the manner of drawers. The power supply unit is housed in a small casing attached to the casing containing the air treating elements, and consists of a transformer 27 provided with a leakage path 31. The primary coil 33 is supplied from a commercial supply circuit 26. The charging of the wires 7 is obtained in the arrangement shown from the part of the secondary between the terminal 60 and the tapping 55 and the circuit includes the two rectifiers 36, 37 in series. The charging of the plates of the precipitator elements is derived from the part of the secondary between the terminal 44 and the tapping 55. Condensers 40, 41 are disposed in series with the rectifiers. A change over switch 62 is provided and is actuated by an electromagnet 69 energized when the switch 70 is closed either by hand or automatically. A switch 72 is disposed in the lead 45 to the charged plates 20, so as to throw this element out of action when desired. One of the electrodes 81 of the ionizing chamber may be insulated and connected to earth through a lamp 75 to indicate short-circuiting through the accumulation of dust and the necessity for cleaning. Earthing of the casing may be through a high resistance 78 to one of the leads of the primary circuit. The primary circuit has a switch 80 which is normally open and is closed only by the closing of the door of the casing of the power unit. The doors of the casing containing the ionizing and precipitating elements and of the power unit casing are also interlocked so that the latter cannot be closed until the former is closed. Opening of the door of the power unit casing also allows spring actuated contacts to de-energize the condensers 40, 41. The usual electrode cleaning devices such as rapping or flushing means may be provided.

Title: Improvements in or relating to dielectric heating equipment
Inventor: TIBBS CHRISTOPHER EVAN MUNDELL
IPC: H05B6/36
Filed: 1958-07-30
Abstract: 859,880. R. F. couplings. RADIO HEATERS Ltd. July 24, 1959 [July 30, 1958], No. 24569/58. Class 40(7). [Also in Group XXXV] In dielectric heating equipment of the type in which the utilization circuit is inductively coupled to the oscillator tank circuit by means of a radio-frequency transformer, arrangements are made to increase the coupling between the transformer windings to improve stability and reliability. A known heating equipment circuit includes an oscillator valve 10 and a tank circuit consisting of capacitor 14 and the primary winding 16 of the output transformer. One end of the winding 16 is connected to earth either directly or through a capacitor 20 shunted by grid leak 18. The secondary winding 22 of the transformer has the end nearest the primary earthy end connected directly to earth. whilst the other end is at high A.C. potential. The voltage between the high voltage adjacent ends of the two windings is considerable and in a practical transformer wherein the coils are wound in opposite directions is approximately twice that developed across the tank coil. An air insulation gap between primary and secondary sufficient to prevent flash-over at this end of the transformer is unecessarily large where the voltage differences are lower and therefore, according to the invention the spacing between the primary and secondary winding is made to vary from point to point in accordance with the working voltage difference. In one transformer embodiment the primary winding is formed of two turns of copper strips 16a and 16b coupled in series by a copper bar 16c. The terminal plate 34 at one end of the winding is connected to the tank circuit capacitor and the strip 26 at the other end is connected to the earthy side of the circuit. The two primary turns are of the same diameter. The secondary also consists of two turns 22a and 22b and is formed from a spiral of copper strip of gradually increasing radius from the end coupled to earthing and supporting bracket 36 up to the end turned over to form output connection 38. As may be seen in Fig. 2 the spacing d 1  near the earthy ends of the windings is considerably less than the spacing d 2  near the ends having the greatest voltage difference.

Title: Improvements in or relating to justification computation mechanism
Inventor: GRUBE WOLFGANG OTTO
IPC: B41B27/36
Filed: 1966-06-03
Abstract: 1,114,533. Photographic type-composing. ELTRA CORPORATION. 3 June, 1966 [14 June, 1965], No. 24814/66. Heading B6W. A photographic type-composing machine is controlled by a 6-unit coded tape which does not include justification information, the tape being fed forwards rapidly past a tape reader while the character signals are converted to width signals which are passed to a justification computer; sensing of an end-of-line signal then causes rapid reverse feeding of the tape until the previous end-of-line signal is sensed, whereupon the tape is fed forwardly a second time at a slower speed to cause the composing of the line under the control of the character signals and the justification computer. Sensing of the end-of-line signal causes further rapid forward feed to begin the justification calculation for the following line. The rapid feed in both directions is controlled by a clock pulse generator, and the slow feed is controlled by the composing machine, which may be as disclosed in Specifications 801,481 or 905,456. Alternatively, the tape may be stationary and the tape reader reciprocated past it. The font and case are selected during the justification calculation tape run by means of width cards in the form of interchangeable removable plugs in the circuits to the width counter.

Patent GB-1000570-A (GB)
Title: Methods of manufacturing thin film conductors and to conductors manufactured thereby
IPC: H05K3/14
Filed: 1963-06-25
Abstract: <PICT:1000570/C6-C7/1> A thin film electrical conductor is made by first vapour depositing a layer of nucleating material (e.g. Au, Ag or Cu) on an insulating substrate (which may include a layer of SiO) and then vapour depositing a thin film of electrically conductive material (e.g. In, Sn or Pb) on the nucleating material, the thickness of the nucleating material varying from a value above a critical range to a value lying within or below the critical range, the critical range being a range of thickness of the nucleating material in which agglomeration of the thin film of conducting material when vapour deposited thereon is inhibited so that the conductive material forms a continuous film.  Fig. 2 shows a substrate 20, with an insulating layer 21, e.g. of silicon monoxide, a Au nucleating layer 22 which is 100 angstroms thick, and a film 23 of In which is 2000 angstroms thick.  The Au nucleating layer was deposited through a mask and the edges 22a, 22b of the Au layer are slightly tapered due to shadowing effects during the deposition.  At those regions above the tapered Au edges where they are between 5 and 10 angstroms thick the In film 23 is continuous and conductive. Everywhere else the In agglomerates, is discontinuous and effectively a non-conductor. The continuous part of the In forms a conductor 5-10 microns wide. The discontinuous portions of the film can be made more discontinuous by heating the entire structure after the films have been deposited. Different width conductors can be produced by producing a different taper to the edge of the Au nucleating layer, e.g. by using different distances between the mask and evaporant while vapour depositing the Au.  In another example, a strip conductor is produced by depositing nucleating Au through a mask having a slot with a narrow wire across its centre.  The substrate area beneath the wire receives less Au than that beneath the open areas but does receive some due to shadowing. The mask is removed and In is deposited.  Only that part of the In which overlies that part of the substrate which was partly masked by the wire is continuous and conductive.  Any desired pattern of conductors can be fabricated.

Title: Toner Dispensing Apparatus in Electrophotographic Copying Machines
IPC: G03G15/10
Filed: 1967-05-31
Abstract: 1,191,943. Developing electrostatic images. PITNEY-BOWES Inc. May 31, 1967 [May 31, 1966], No. 25166/67. Heading G2H. Toner is pumped into a developing tank in quantities proportional to the length of an original and thus to the length of copy paper fed through the tank. As shown, rollers 110, 112 Fig. 5, driven by a motor 114 through a chain 24 feed the original which trips a switch 122, energizing solenoids 98, 120, the former attracting an armature 96 which is connected to, and thus pivots, a lever 90. The lever 90 supports on a shaft 88 a sprocket 94, engaging the chain 24, and a gear 86 Fig. 2 which pivots into engagement with a gear 84 to drive a shaft 76 and thus a roller 72 and a gear 80. Gear 80 meshes with a gear 82, to drive a roller 74, and with a gear 66 having a cam 60 shaped to allow pivoting of a lever 56 by a spring 70 through a follower 58 on each revolution of gear 66. This movement, through shafts and levers 54, 52, 50 produces one stroke of a pump 34 which pumps toner from a bottle 26 via a tube 42 into a tank 20 of developer 22. The pump operates periodically as long as the switch 122 is held open by the passage of the original. A stop 134 lies in the path of a member 132 fixed to the shaft 52 and may be manually adjusted to limit rotation of this shaft and thus limit the amount of toner fed during each pump stroke. As previously stated, switch 122 starts rollers 72, 74 and these feed copy paper from a roll 130 into a cutting device 118 having a blade (not shown) retracted on energizing of solenoid 120 and released on release of switch 122 to sever a length of copy paper equal to that of the original. Rollers 102, 104, 106 driven by the chain 24, feed the copy paper through the tank 20 after exposure to the original.
