Title: Multi-layer capacitors and processes for adjusting the values thereof
IPC: H01G4/30
Filed: 1971-04-19
Abstract: 1340414 Capacitors ILLINOIS TOOL WORKS Inc 19 April 1971 [20 April 1970] 27249/71 Heading H1M In the manufacture of a multilayer ceramic capacitor wherein alternate electrode layers extend to different faces of the capacitor body to be electrically interconnected by end contact layers 44, 45, at least one electrode layer, e.g. 381, 40<SP>1</SP> stops short of the contact face. The capacitance can then be adjusted upwardly by cutting a groove (Fig. 1, not shown), or grinding the contact face or tumble milling to expose the edge of the concealed electrode layer and remetallizing the contact face so that it now contacts the electrode. In a modification (Fig. 10, not shown) two such electrode layers intended to be of opposite polarity are each divided longitudinally and either part or the whole of each layer can be brought into play to provide a range of adjustment possibilities. In a further modification (Fig. 11, not shown, and Fig. 12), there are sandwiched between dielectric layers 66, electrode patterns comprising parts 68A, 68B and 68C and 70A, 70B and 70C. By selecting the regions X at which electrode edges are exposed, capacitance can be increased through a decade. The Fig. 11, 12 arrangement can be added to a capacitor stack to provide fine adjustment of the capacitance. In the Fig. 13 arrangement, by grinding and resilvering to make contact with portion 78a<SP>1</SP>, the capacitance is increased threefold, and by further bringing portion 80a<SP>1</SP> into contact a further threefold increase is achieved. Alternatively portions 78a<SP>1</SP>, 80a<SP>1</SP> may initially extend to side faces adjacent to the contact face where they are contacted by the end contact layers extending on to the side faces, and the capacitance can be reduced by one third or one ninth by removing parts of the contact layers (Figs. 15A to 15E, not shown).

Abstract: 751,743. Inlet ports; arrangement for fuel injectors and igniters. TEXACO DEVELOPMENT CORPORATION. Oct. 9, 1953 [Oct. 27, 1952], No. 27806/53. Classes 7(2) and 7(3) INLET PORTS In an arrangement of air intake ports in an engine of the uniflow-scavenged type in which the air whirls around the cylinder axis and is introduced into the cylinder 12, Fig. 1, through ports 20, Fig. 2, uniformly distributed in the cylinder wall, and wherein combustion of the air-fuel mixture is effected by a single flame-front, each of the ports having a flow axis perpendicular to the cylinder axis, the opposed walls of each port being parallel, and the downstream side wall of each port being disposed tangentially to the main wall of the cylinder, the width of each port is approximately one-half the cylinder radius so that the total number of ports is small, preferably six. The angle between the adjacent walls of adjacent, ports is 60 degrees and the height of each port is three-quarters of its width; each port has an associated vane 40, the length of which is one-third of the port length, the spacing between the vanes and port walls being such that the arc of each port, where it enters the cylinder, is bisected by the vane centre-line. The downstream wall of each port is disposed tangentially relative to the inner wall of the cylinder or to a circle having a diameter of 95 per cent of that of the cylinder. The trailing vane edges may either be rounded or as shown in Fig. 2. GENERAL CONSTRUCTION AND OPERATION The cylinder 12, Fig. 1, of a two-stroke engine has two exhaust passages 19 leading to a common manifold (not shown), each passage being provided with a poppet valve 18 whilst an intake manifold 21 opens into the piston-controlled ports 20 located above the B.D.C. position so that air drawn therethrough swirls around the cylinder at 4-9 times the engine speed. A fuel nozzle 26 is arranged to direct a coneshaped spray into one side of a diameter of the disc-shaped combustion-chamber 25 in the direction of air swirl to impregnate a localized segment of the air at a fuel-air weight ratio of 0.05-0.09; fuel injection is initiated 50-20 crank-angle degrees before T.D.C. and continues for 80-90 per cent of the time required for the air to complete one swirl. For reduced load conditions the injection period is reduced. Ignition is effected by glow-plug, compression, or, as shown, by a sparking plug 30 located 20 degrees-75 degrees downstream of the fuel nozzle with its electrodes 31 positioned close to the periphery of the combustion space; the spark occurs at 4-10 degrees crank angle after the fuel injection commences to ignite the impregnated segment and form the flame front. Specifications 596,846 and 666,507 are referred to.

Abstract: 898,718. Distributing conveyers; piling material. MAVOR & COULSON Ltd. Aug. 22, 1960 [Aug. 14, 1959], No. 27810/59. Classes 78 (1) and 78 (4). Apparatus for piling material comprises an endless driven conveyer belt 10, which is carried by a frame 12 mounted by a ball-andsocket joint 37 on an advancing bogie 30, which runs on rails 34, the opposite end of the frame being supported on a bogie 31 adapted to move to and fro along a rail track 61 arranged transversely to the rails 34, so that the delivery end of the belt is swung through an arc as the bogie 30 is advanced, and the material thereby distributed to form a pile. The advancing bogie 30 includes a winding drum 42 with which is associated a ratchet-wheel adapted to be rotated step-by-step by a pawl carried by the frame 12 so that as the latter swings to and fro a cable 46 anchored at 47 is wound up on the drum 42 to advance the bogie 30 and hence the frame 12. During this advancing movement the frame 10 slides over the transverse bogie 31 by rails 50 on the former engaging supporting rollers 55 on the latter. The bogie 31 is driven by a motor 32 controlled by two reversing switches 71, actuating plunger 72 of which engage ramps 73 at the limits of movement of the bogie. Motor 32 drives one of the two track-engaging wheels 60 through reduction gearing. When the frame 12 has advanced a distance equal to the length of rails 50, screw jacks each comprising a screw 85 operating in a housing 86 pivoted to the bogie, and a nut 88 engaging the screw and pivoted to an arm 90 on a shaft 83, are manually operated to rotate the shaft 83 which in turn operates parallel linkages 81, 84 to lower four wheels 80 into engagement with rails 62 forming extensions of the rails 34 and crossing the rail 61. This raises wheels 60 from the latter rail so that the bogie 31 can be advanced to a new position where a second set of rails 61, 62 is provided. The rails 62 of this second set are subsequently joined to the rails 62 of the first set by rails 34. Legs 100 on the frame 12 carry feet 101 for smoothing the material over the ground in preparation for each further set of rails 61, 62. The belt 10 is fed via a shoot 19 from a shuttle conveyer which also runs on the rails 34 in overlapping relation with a main fixed conveyer from which the material is received.
