Title: Conveyor system and method of automatically transporting articles thereon
IPC: B65G47/49
Filed: 1965-12-28
Abstract: 1,140,382. Conveyer system and control. DORR-OLIVER Inc. 28 Dec., 1965 [28 Dec., 1964], No. 54921/65. Headings B7L and B7N. In a chain driven conveying arrangement in which containers 68 fitted with slides 76 are conveyed along a track formed by a pair of U- shaped members 96 disposed with their open sides inwardly directed to receive the slides, addressing pegs 88 are provided on each container which coact with switches at stations along the track to divert the container from the main track at the addressed station and means are provided for introducing a container on to the track in a position which does not foul existing containers on the track. The vertical wall 102 of each rail is formed at spaced points with openings 104 and parts of this wall 106a, 106b adjacent the openings are curved outwardly to guide the endless driving chain 110 which runs within the channel and is engaged by hook members 114 on each slide. The return run of the chain is guided by angle member 124 and the chain is tensioned by spring 122 acting on a slidable pillow block 118. Containers enter the main run from below an upwardly rising track 140, Fig. 11, the rail on the drive side of this track has its upper wall cut away and the opposite rail its upper and vertical walls 170 cut away and theirl ower walls extended to connect with the lower walls of the following section of track. The upper and lower walls of the main track are pivoted and are lifted by the slides as a container enters the main track from the rising track. The drive to the chains on the rising and main tracks are synchronized so that the free hooks on the left side of each container automatically engage the main track drive chain as the container enters the main track. Containers leave the main track via a downwardly sloping track, Fig. 10 (not shown), which is a continuation of the main track. The diverging point is connected to the following length of main track by a pivoted track section controlled by a solenoid. The solenoid is operated to pivot the track section out of its through rim position when a vehicle has to be diverted from the main track. The addressing pegs 88 are selectively positioned transversely of the container and coact with switches positioned in advance of the selected station to actuate the diverging mechanism to route the container to the station.

Title: Automatic Transfer of Calls
IPC: H04Q3/62
Filed: 1966-12-08
Abstract: 1,172,850. Automatic exchanges. TELEFONAKTIEBOLAGET L. M. ERICSSON 8 Dec., 1966 [8 Dec., 1965], No. 55106/66. Heading H4K. In a semi-automatic P.B.X if a called extension fails to reply within a predetermined time the call is automatically diverted to a predetermined other extension. The exchange employs register controllers, such as REGL, into which a wanted number is dialled by an extension A1 to AM, or such as REGO, which is connected to an operator's link circuit OPL, for an incoming call on line FL1, and into which register the operator keys the wanted extension. A translator ANL has pairs of input wires L1-LM each pair representing a directory number. An x-link is provided in the distributon frame MK connects one wire of an L-pair to magnetic core read-wire representing the corresponding equipment number. A y-wire, if provided, connects the other wire of an L-pair to the magnetic core read wire corresponding to the equipment number of the extension to which a call may be diverted in the event of the first not answering, or being unobtainable, i.e. x-link absent. A free relay circuit OM on being seized by a register REGL is connected over selector V to that pair of wires of L 1  to L M  corresponding to the directory number set in the register. If both x and y links are present relays DR2 and DR3 operate and cause an interrogation pulse to traverse the translator over the x-link causing the equipment number of the wanted extension to be read into register AK. Marker SLM receives the number to set up the connection to the wanted extension. Relay circuit OM is then released but register REGL is held. If after a delay set by timer TD in the register REGL the wanted extension has not replied, the connection to that extension is released. A free relay circuit OM is seized and connected to the L-pair of the previously rung wanted extension. Relay DR1 is now operated by TD and an interrogation pulse now traverses the translator over the ylink so reading out to register AK the equipment number of an extension to which calls are to be diverted. A connection is now set up to the new extension by marker SLM. In the event of a call to a number which is unobtainable i.e. x-link absent only relay DR3 operates and the call is immediately diverted to a different extension as determined by the y-link. The translator ANL is described in Specifications 1,167,177 and 1,117,890.

Filed: 1972-12-01
Abstract: 1456638 Continuous winding WINGET Ltd 30 Nov 1973 [1 Dec 1972] 55508/72 Heading D1J The invention relates to spooling apparatus of the kind comprising co-axially spaced reels 12, 14 driven in sequence at a varying rate of rotation such that the peripheral speed at the surface of the wound strand remains constant, the apparatus including means for transferring the strand from a full reel to an empty reel, and notched catcher plates 34 abutting adjacent flanges of the reels 12, 14 to catch the strand and sever it against a stationary cutter 24. According to the invention a wire carrier 30 of cradle form is positioned between the two reels 12, 14 and in the strand is transferred from one reel to the other the strand is laid in this carrier. The carrier is on an arm 26 that is then rocked towards a pair of cutters 24 but before reaching these cutters the carrier 30 is itself pivoted relatively to the arm 26 to cause the strand to slide off the carrier 30 and onto the notched catcher plates 34 rotating with the spools 12, 14. Notches 32 on these plates then carry the strand past stationary cutters 24. In Fig. 2 the arm 26 is rooked by a pneumatic cylinder 40 anid the carrier 30 is rocked by a pneumatic cylinder 38. Winding transfer tails. In Figs 3 and 4 (not shown), there is between each spool and its associated notched catcher plate 34 a dummy reel (52, 54) on which may be wound a length of leading-in strand. In this instance the yarn carrier (77) between the two spools is supplemented by outer yarn carriers (56, 58) one on each side of the carrier (77) and swingable in the plane of an associated dummy reel (52, 54). All three carriers are mounted on their own individual pivotable support arms. When the strand is transferred from a full spool to an empty spool the strand is first draped across all three carriers (56, 77, 58) and then the supplementary yarn carrier (56 or 58) associated with the empty spool is swung forwardly, such forward movement carrying the central carrier (77) with it. This causes the strand to be snagged by both catcher plates and the empty dummy reel 52 or 54 to have a lead-in strand wound thereon.

Filed: 1969-11-24
Abstract: 1293807 Semi-conductor device GENERAL ELECTRIC CO 24 Nov 1969 [9 Dec 1968] 57442/69 Heading H1K [Also in Division C7] A junction containing semi-conductor wafer is passivated by covering at least one of the surfaces with insulation to leave certain areas exposed, removing material from these areas to below a junction and electrophoretically depositing a passivating material, e.g. glass or plastics, into the grooves so formed. Typically a silicon wafer with several junctions is surface oxidized in steam, has registering grids cut in the oxide on opposite faces by etching through a photo-resist or wax mask and is then treated in an etchant to form intersecting sets of grooves extending through the junctions nearest to each face. The oxide overhanging the grooves may be left or removed by brushing or immersion in an ultrasonically agitated inert fluid. An oxide layer up to 500 Š thick is next formed on the groove walls preferably by treatment with an oxidizing agent such as hydrogen peroxide of strong nitric acid. This treatment improves adhesion of the glass electrophoretically deposited in the next step, in which a number or wafers are treated sequentially in an apparatus, operation of which is described in detail. If the oxide overhang was removed the glass increases in thickness towards the base of the grooves, while if it is left on the reverse is true. After firing to coalesce the glass particles electrodes are provided, either before or after sub-division, e.g. by scribing along the grooves, in apertures grit blasted or etched through the oxide. In the completed controlled rectifier shown in Fig. 8 in which the electrodes consist of superposed vapour deposited layers of chromium, nickel and silver, one electrode is soldered to heat sink 804. The wafer is then coated with resilient silicone rubber 814 and a rigid silicone casing 812 injection moulded around it. The invention is also described applied in PN, PIN, PNP and NPN structures with the grooves sometimes limited to one face.
