Filed: 1969-08-29
Abstract: 1,267,840. Television. AMPEX CORP. 29 Aug., 1969 [30 Aug., 1968], No. 43143/69. Heading H4F.  A network for fading over from one video signal to another comprises two video inputs 3, 5 respectively coupled to a common output 7 through electrically controllable attenuators 27, 27<SP>1</SP>, each of which has a plurality of discrete selectable levels of attenuation. Preferably, the levels of attenuation in the two attenuators 27, 27<SP>1</SP> are controlled complementarily so that as one increases the other decreases. The levels may be regularly spaced. Each attenuator 27 or 27<SP>1</SP> includes a number of parallel connected field-effect transistors switchable between conductive and non-conductive conditions by binary control signals from a driver network 29-38. Resistances (49), Fig. 2 (not shown), in series with each transistor (43) have their values arranged so that as the transistors are successively switched the degree of attenuation of the corresponding video signal progressively changes. The number of transistors (43), and hence the number of parallel alternative paths through the attenuator, corresponds to the number of bits of a binary code number used for controlling the fade over. In the network shown, the control number contains six bits determined by a bidirectional coun er 39 adapted to count from binary all-zero to binary all-unity or vice versa (see Division G4). Each bit is applied to a corresponding one of the attenuator drivers 29-38, each of which includes a Schmitt trigger circuit providing an " on " signal to a transistor in one of the attenuators 27, 27<SP>1</SP> while it provides an " off " signal to the corresponding transistor in the other attenuator. A control logic circuit 41, operated by remote inputs, supplies the necessary control signals to the counter 39 to initiate fade over and to control the rate at which it progresses.

Filed: 1973-09-13
Abstract: 1395141 Magnetic separation OCCIDENTAL PETROLEUM CORP 13 Sept 1973 [18 Sept 1972] 43173/73 Heading B2J A mixture of glass particles is divided into fractions having different magnetic properties by passing a stream of such a mixture through a magnetic field which is of greater intensity at one side of the stream than the other, thereby to cause migration of particles laterally of the stream in accordance with their respective magnetic properties. As shown, a hopper 10 distributes a mixture of diamagnetic, paramagnetic and magnetically neutral particles - typically represented by "flint", "green", and "amber" glasses respectively - on to a tilted chute conveyor 12 down which the particles slide to pass as a band through a magnetic field produced by electromagnets having pole pieces 14 arranged to produce a field which is relatively strong near one side of the band and relatively weak near the other side. The diamagnetic and paramagnetic particles experience respectively magnetic repulsion and attraction from the regions of higher field intensity and thus tend to move to opposite sides of the band where they are separated into two fractions by a mechanical divider 16, both fractions also containing neutral particles. The chute may be tilted laterally through a small angle # to impose gravitational forces on the particles, whereby, as shown, the neutral particles will tend to collect with the paramagnetic particles. The chute 12 may be replaced by a moving belt, a turntable or a vertical-fall arrangement, and the process may comprise a plurality of separating stages (Figs. 2 to 6, not shown).

Title: Improvements in or relating to transistors

Filed: 1962-11-27
Abstract: 1,031,157. Transistors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Nov. 27, 1962 [Nov. 30, 1961], No. 44827/62. Heading H1K. In a junction transistor wafer the part of the base zone (e.g. 3 in Fig. 2), adjacent the emitter junction is produced by vapour phase epitaxial growth or impurity diffusion and is joined to a surrounding similarly produced portion 4 extending the full thickness of the wafer. This portion which carries the base electrode also surrounds either the collector-region or, as shown, a second higher resistivity portion 7 of the base zone. A typical device is made in multiple from a P-type germanium wafer by first etching, grinding or ultrasonically cutting material from both faces to leave only island portions of the original thickness. Alternatively, further semi-conductor material is deposited from a saturated solution of germanium in indium, gallium, aluminium, lead or tin applied at the desired sites of the thickened portions. Antimony is vapour-diffused into the treated wafer until the diffusion fronts overlap except in the thicker portions. The wafer is then ground to a uniform thickness to yield islands of P material in an N-type wafer. The surface of the islands are rendered concave by an electrolytic etching technique which is described in detail. A similar structure may be formed simply by vapour depositing silica to mask the island portions and then diffusing antimony into the unmasked area. The silica may be deposited through a mask or deposited over the entire surface and subsequently selectively removed by photolithographic techniques. As a further alternative a photoresist is applied, exposed to a light pattern and the unexposed portions removed. The thus exposed wafer areas are rendered concave by electrolytic etching and then silica is deposited on the surface. This adheres to the concave areas but is removed from the remaining areas together with the underlying photoresist to form the diffusion masking. Single device portions, each consisting of a P-type annulus with an N-type core can be cut from the resulting wafer. Such annuli may alternatively be sliced from a circular N-type rod the surface of which has been converted to P-type by diffusion. In all the above cases the core may alternatively be intrinsic or high resistivity N-type. The base zone proper and emitter are preferably formed simultaneously by alloying a pellet of lead, antimony and gallium to the concave region by heating to 780 C. in hydrogen for 10 minutes, antimony diffusing from the pellet to form a thin base region 3 joined to the annulus. The collector electrode, or where the core is of intrinsic or N-type the collector zone, is formed at the opposite face by a separate alloying step using indium gallium alloy. Alternative semi-conductor materials are germanium and A III B v  compounds. In other embodiments the concave recess is deepened prior to alloying the collector, and the base zone proper formed by epitaxial deposition or diffusion before the emitter is alloyed in.
