Abstract: 1488151 IGFETs AMERICAN MICROSYSTEMS Inc 29 Aug 1974 [29 Aug 1973] 37837/74 Heading H1K In an IGFET (e.g. 12a in Fig. 2) comprising an N-type source region 10 forming the substrate for a P-type base region 16 in which the acceptor doping increases with distance from the source, and a relatively lightly doped drift region 18, with an N-type drain region 20 formed at its surface, a V-groove 24 extends downwards into the substrate to expose an edge of the base and drift regions to which gate electrode 28 is applied. The device shown includes channel stop layer 23 and is integrated with other devices of similar type sharing the same source region. In another described structure a pair of such transistors on a common source region with interconnected drain regions series connected with a diffused or ion-implanted resistor form a NOR logic circuit. Manufacture normally starts with an N-type substrate which also contains acceptor impurity distributed through it or diffused or ion-inplanted into its surface. Then a lightly doped epitaxial layer is deposited and acceptor impurity diffused into it from the substrate to form the base and drift region. Alternatively a suitably graded base region is epitaxially grown on an N-type substrate ahead of the lightly doped layer, rendering the outdiffusion step unnecessary. The channel stop layer and drain are then diffused by a method which is described in detail, the V-groove formed using an anisotropic etchant, the silica gate insulation grown, polysilicon deposited, doped and patternetched to form the gate electrode and a contact pattern of aluminium formed by overall deposition and masked etching.

Patent GB-830013-A (GB)
Title: Process for the preparation of a stable dispersion
IPC: B29B9/00
Filed: 1956-12-14
Abstract: A stable dispersion of natural resins in oxidized form is made by suspending the finely powdered oxidized resin in water heated to a temperature below 100 DEG  C., i.e. below the softening point of the resin, adding a saponifying agent and a protective colloid and submitting the mixture to mechanical mixing e.g. in a colloid mill. Alkali bases, e.g. caustic soda, sodium carbonate, caustic potash, or organic bases may be used, and partially saponify the resin or resinic acid which may be rosin, rosin pitch, or colophony, artificially or naturally oxidized.  In an example oxidized rosin is finely powdered and added to water at 50 DEG  to 100 DEG  C. to which ammonia is added in sufficient amount to give a pH value of 7, together with casein, starch or gelatin to form a viscous coagulum, which is then connected to a fine dispersion in a colloid mill.  The product may then be diluted, using hot water in a first stage and cold water in the second.  It may be used as an adhesive or binder.

Abstract: 345,260. Controlling machinery guards. BLOMLEY, F., TOMLINSON, H., and TWEEDALES & SMALLEY (1920), Ltd., Globe Works, Castleton, Lancashire. Dec. 14, 1929, No. 38349. [Class 80 (iv).] In a device for coiling slivers in a carding-engine, combing-machine, lap machine, or the like, the separation or disengagement of the driving and driven wheels a', a<8>, Figs. 1 and 3, of the coiler mechanism must be effected prior to the opening of the coiler lid E and is independent of the movement away from its operative position of the member d<2> which, during coiling, prevents opening of the coiler lid, the disengagement also, if desired, serving to unlock the coiler door C. Two levers A, D are pivotally mounted on the coiler pillar B, one end of the ]ever A being formed with a hook a<1> and the other end being connected by a link a<2> to a lug or arm a<3> which passes through an inclined cam-slot a<4> in a boss a<5> attached to the pillar B, the inner end of the arm a<3> being fixed to a bush or sleeve a<6> in which is rotatably mounted the driving-wheel a7, the bush a<6> being slidable and rotatable in the boss a<5>. The lever D is formed at one end with two recesses d, d<1> and at the other end with a crank portion d<2> which is adapted to extend over the coiler lid E. It is also provided with a drop latch d<3>. When the wheels a<7>, as are in gear, the crank portion d2 extends over the lid E and prevents it from being opened, the hook a<1> occupying a position in the recess d<1> and abutting against the door C to maintain it shut. The drop latch d<3> is also moved to abut against the side of the lid E, as shown in Fig. 3, thereby preventing movement of the lever D which would disengage the hook a<1> and permit the coiler to be started with the lid closed. To unlock the lid E the latch d<3> is raised, Fig. 4, the hook a<1> disengaged from the recess d<1>, and the lever A turned about its pivot a, thereby causing the lug a<3> to travel along the slot a<4>, the wheel a<7> being disengaged from the wheel a<8> and the hook a<1> coming into register with an aperture c in the door C, which can then be opened. The hook a<1> also comes opposite the recess d in the arm D, which can then be turned, as in Fig. 4, to move the end d<2> clear of the lid E. To restart the coiler, the door C and lid E must both be closed and the parts moved back to the positions shown in Figs. 1 and 3.

Abstract: 1,141,130. Turret tuners. MATSUSHITA ELECTRICAL INDUSTRIAL CO. Ltd. 20 Sept, 1967 [21 Aug., 1967], No. 38432/67. Heading H3Q. [Also in Division H1] A U.H.F./V.H.F. turret tuner has a first disc with contacts co-operating with a pair of stator contacts (one joined to the V.H.F. aerial and the other to a V.H.F. amplifier), a second disc also with contacts co-operating with a pair of stator contacts (for V.H.F. local oscillator connections), a third stator contact (joined to the U.H.F. tuner output) associated with the first disc, and a fourth stator contact (connecting power to the U.H.F. tuner) associated with the second disc, the third and fourth stator contacts making to one of the corresponding pair of contacts in the U.H.F. position of the turret. Thus in the V.H.F. positions of the turret signals are fed from the V.H.F. aerial to the V.H.F. amplifier transistor, and the local oscillator transistor is supplied with power, while the U.H.F. tuner has no power and its output is disconnected (Figs. 5 and 7, not shown). On the other hand, in the U.H.F. position of the turret, signals are fed from the U.H.F. tuner (which converts them to V.H.F.) to the V.H.F. amplifier, while the V.H.F. aerial is disconnected and power is removed from the V.H.F. local oscillator. Turret construction.-Each disc has rotor contacts 28 around its periphery (Fig. 3), adjacent ones being joined to coils 15 and via stator contacts 22, 27 to the external circuit. In the U.H.F. position contact 29 is blank and 30 is omitted, so that stator contact 22 can move further inwards under the influence of a spring (not shown) whereby an extension thereon (Figs. 2 and 13, not shown) makes with the third stator contact 23. In another form (Figs. 10 and 12, not shown) there is a raised portion or dummy contact in position 30 so that the stator contact 22 is moved outwards to engage contact 23. The rotor contacts 28 may project beyond the edge of the disc (Fig. 11, not shown). The turret carries further discs (without contacts 23) for switching an interstage tuned amplifier (Fig. 2, not shown).
