Abstract: 1375860 Harvester INTERNATIONAL HARVESTER CO 16 Dec 1971 [16 Dec 1970] 58461/71 Heading A1F A mower conditioner has a main frame 3 upon which is carried a sub-frame 4 of a header 5, a mower 14, crop conditioning rollers 24, 25, aerating bar 30 and deflector shield 62. A reel 16 carring spring fingers 17 sweeps the crop to the mower end after cutting, the fingers carry the crop to the conditioning rollers 24, 25. The aerating bar 30, which is positioned transverse to the stream of material discharged from the rollers 24, 25, comprises a tubular bar 35 carrying a series of longitudinally spaced fingers 38 which are resiliently mounted. The tines at the ends of the bar are inclined inwardly and downwardly, Fig. 2. Part of the crushed crop impinges against these tines and is shed toward the ground to form a first layer 58 of a swath of conditioned crop. That part of the crop which passes through passageways 46 formed between guides 45 and end tines 38, enters windrowing means 50. This means has side sheets 49 arranged to fold material passing through into a top layer 56 of swath 60. An intermediate layer 63 consists of material which passes through spaces 39 of tines 38 and rebounds against the underside 59 of deflector shield 62. The aerating bar 30 can either freely swing in a range defined by a pin and slot or be locked in a position which permits all of the conditioned crop to strike underside 59, Fig. 6. Several modifications are described in which (a) The aerator bar is positioned behind the deflector shield. (b) The window side panels are adjustable to control the width of the swath, and the aerator bar is positioned beneath the deflector shield. (c) The spaces behind the tines are partially blocked off by a plate which extends the full length of the aerating bar, and which may be fixed in various positions of inclination relative to and behind the tines. (d) A plate is fixed to the front of the aerating bar, which is directly behind the main frame. The plate and bar may be locked in a number of inclined positions relative to the flow of the conditioned crop. In modifications (b), (c) and (d) the tines, which slot into apertures in the tubular bar 35, have loops 170 at their ends to permit ease of removal and insertion.

Title: Method of Fabricating Semiconductor Devices
Inventor: MANKARIOUS RAMZY GUINDY
IPC: H01L21/203
Filed: 1968-12-16
Abstract: 1,183,170. Semi-conductor devices. HUGHES AIRCRAFT CO. 16 Dec., 1968 [18 Dec., 1967], No. 59709/68. Heading H1K. A layer of semi-conductor material is epitaxially deposited in vacuo and at least a selected portion is simultaneously bombarded with ions of a second material. This method allows parts of an epitaxial layer to be selectively doped during deposition and may also be used to produce abrupt junctions. The epitaxial deposition may be effected by heating a source of the semi-conductor material in vacuo to produce a vapour which condenses on a suitably heated substrate. An ion source directs a beam of ions of the second material on to the substrate as required to dope the deposited layer, and more than one ion source may be utilized simultaneously. The substrate is polished, etched and cleaned before deposition of the layer. The method may be applied to the production of diodes and transistors. A metal base transistor, Figs. 5 and 6 (not shown) is made by epitaxially depositing a layer of silicon and simultaneously ion implanting gold on an N-type substrate to produce the conductive base region. When the desired thickness of base region has been deposited the gold mplantation is stopped and an X-type epitaxial layer is grown. The N-type layer may be doped by implantation of antimony ions or by conventional methods. A varactor diode, Fig. 7 (not shown), is produced on a high conductivity N-type substrate by epitaxially depositing an N-type layer of lower conductivity followed by a P- type layer, both layers being doped by ion implantation. A buried region, Figs. 8 and 9 (not shown), is produced by epitaxially depositing an N-type layer on a substrate followed by a layer comprising a P-type region surrounded by an N-type region, which is itself followed by a further N- type layer which may have a small P-type portion providing a connection to the buried layer. The regions of different conductivity type are produced by selectively implanting impurities in the epitaxial layers as they are grown using two simultaneously energized ion sources.

Abstract: 1396089 Preheating pulverulent material; cement kilns POLYSIUS AG 31 Dec 1973 [13 Feb 1973] 60255/73 Heading F4B Pulverulent material, e.g. raw cement meal, is preheated in the exhaust gases from a rotary furnace, mixed with fuel in a zone in which combustion does not take place, prefired in a further zone and finally fired in the rotary furnace. Material preheated in a series of cyclones is fed from the last cyclone 2 to a passage to which oil is supplied through a nozzle 9 and transport air through a co-axial passage 8. The oil fuel burns when the mixture reaches the connecting chamber 4 between a rotary kiln 1 and the preheater gas inlets, prefired material falling into the kiln or being carried with the kiln gases 5 to the preheater. Two cylone preheaters with separate mixing zones may discharge into the connecting chamber, or the prefiring zone may be the first section of the rotary kiln, or a cyclone separator may be used as the prefiring chamber.

In Fig.1, the signals a-e from the innermost gimbal are successively sampled by a multiplexer 10 (an electronic switch device) the output of which is amplified at 16 and transferred via slip rings 20, 26, 32 to the intermediate gimbal, the outer gimbal, and the casing structure where a second multiplexer 12 separates the signals a'-e'. Signals from the other gimbals may be added by additional multiplexers. Instead of the slip rings, a contactless pick-off using light transmission may be used. In Fig.2, leads 42 carrying the multiplexed signals are guided in a bore of a gimbal shaft to a gallium arsenide diode 38 at the shaft end. Light therefrom excites a photo-diode, phototransistor, or photo-resistor 40 in the bearing structure. Signals may be of analogue or digital form. A parallel multiplexed path may be provided at the other end of the shaft. An audiofrequency signal may be used to monitor the function of the transfer channel.

Title: Laser workpiece position and presence inspector and machine control
IPC: G01V8/20
Filed: 1978-07-13
Abstract: The beam from a laser source 124, is split at 132; one beam is directed to graze part of the top of a workpiece resting upon a lower die for subsequent stamping by the upper die of the press, and is reflected by mirror 142 back past another part of the top of the workpiece to a workpiece position detector 144; the other beam is obstructed by the workpiece, when present on the lower die as detected by workpiece presence detector 146. If, however, the workpiece has not been delivered to the lower die or, if delivered and worked upon, has adhered to and has been carried upward with the upper die, press control system prevents the operation until a workpiece is properly supplied. If the workpiece is present but incorrectly positioned, e.g. tilted, it obstructs the workpiece position-inspecting beam and actuation of the press is prevented until the workpiece has been properly repositioned upon the lower die by the operator. The presence detection path may include a tunnel 212 through the post 22, Figure 6. <IMAGE>
