Title: Intergrated circuit device having internal damping for a plurality of power supplies
Inventor: PHILOFSKY ELLIOTT
IPC: H01L23/495
Filed: 1982-06-16
Granted: 1985-12-04
Abstract: The present invention is directed to an integrated circuit device comprising a lead frame having a ceramic capacitor mounted thereon and forming the support for a silicon chip bearing a multiplicity of circuits, including at least two power supply circuits namely a main power supply circuit and a secondary circuit. The capacitor is shunted across the terminals of the main power supply and the main power terminals of said IC chip. A conductive layer disposed atop the ceramic uppermost layer of the capacitor defines with the uppermost electrode of the capacitor, a second capacitive load of lesser value than the main capacitor, the said second capacitive load being shunted across the terminals of the secondary power supply and a secondary set of power terminals of said chip. The provision of internal capacitive shunting for the plurality of power supplies for the chip enables lead length to the capacitors to be maintained at a minimum thereby minimizing inductive reactance and thus enabling small capacitances to effectively dampen noise and pulses in the circuit.
Patent GB-2120182-B (GB)
Title: Method and apparatus for retreading vehicle tyres
Inventor: GRIPENHOLT NINNEH
IPC: B22D41/08
Filed: 1983-05-05
Granted: 1987-04-08
Abstract: Tyres are retreaded by using a pre-vulcanised tread and an uncured layer of rubber between this and the carcass, the rubber being cured by applying high frequency from above the tread. This rubber is also locally heated at or near its edges by extra heating outside the tyre. - Specifically the same h/f generator is used to heat both the outermost area of the rubber adhesive between carcass and tread and also the edges area of the rubber. The h/f energy is therefore more efficiently utilised, and the edge application is adjusted so that it at least equals the heat losses from those areas. The whole cure of the adhesive rubber layer is thus made more effective. As an alternative to using high loss factor rubber for h/f heating the edges, e.g. a ring of high loss factor material can be applied to each edge area and thus heat up the rubber edges externally. - Method eliminates the usual problem of cooling at the edges when the assembly is cured in an autoclave contg. unheated pressurised air.(0/8)

Title: Ground station for air traffic system - has group of transmitting elements arranged in an arc
IPC: G01S/
Filed: 1974-10-15
Granted: 1978-04-20
Abstract: The transmitting elements can be activated individually or severally at the same frequency firstly in one direction along the arc and then in the other direction. A stationary reference source transmits continuously at a constant frequency to all the points which receive signals from the transmitting elements.
