Patent GB-1529304-A (GB)
Title: Imaging system
IPC: G01S13/89
Filed: 1974-10-24
Abstract: 1529304 Radio ranging RCA BROWN and J DOW 24 Oct 1975 [24 Oct 1974] 46129/74 Heading H4D [Also in Division G1] In an imaging system comprising a single transmitter and an array of echo receivers, image elements corresponding to reflective elements of an object surface are displayed on a screen at positions corresponding to the intersections of equitime loci of the object surface corresponding to echo data relating to the time of travel of a pulse between transmission and reception and to the range of the object surface. A radar imaging system is described with reference to Figs. 15 and 16 in which the transmitter emits pulses of spherically expanding waves and the echoes are detected by either a ring of eight receivers (15), Fig. 17(a) (not shown) or by eight receivers mounted at different radii on a revolving arm turning about the transmitter (18) Fig. 17(b) not shown. For a planar object surface the equitime loci are, strictly speaking, ellipses, but these are approximated by best fit circles (theory given). In Fig. 15, function generator 5 produces a succession of hyberbolically expanding spiral scans centred on respective points on the screen of C.R.O. 3 corresponding to respective receivers (or respective positions of the receivers), each scan beginning at a time lapse after transmission of a pulse, and proceeding at a rate, determined by the frequency of a clock generator 7 which is controlled in dependence on the range of the object as determined by the time taken for the first echo to be received. The function generated by circuit 9 is varied in dependence on the distance between the transmitter and receivers. Each received echo is routed to one of shift registers 45, Fig. 16, depending on the receiver which detected it and occupies a position in the register in dependence on the lapsed time. The contents of registers 45 are read out serially to produce beam brightening, preceded and followed by darkening, there being a circular arc corresponding to the equitime locus for each received echo, intersections of the brightened arcs reinforcing to produce the required image, charge subtraction being employed to remove the non-intersecting portions. For a spherical object surface, Fig. 19 (not shown) the equitime loci are straight lines and may be generated by a circuit described with reference to Fig. 20 (not shown). Means may be provided for selecting different scanning patterns for different object surfaces. Instead of feeding all the equitime loci to the C.R.O. for intersection determination, the intersections may be calculated in a computer, Fig. 21 (not shown) and only those points where more than a given number of loci intersect are displayed, thereby eliminating spurious echoes.

Abstract: 1,130,337. Stripping cable. R. A. COLLIS. 27 Oct., 1965 [13 Nov., 1964], No. 46379/64. Heading H2C. When a metal or plastic-sheathed cable is placed in the lengthwise V-section groove 24 in the lower jaw 23 of the stripping tool and the jaws closed by moving a handle 10 pivoted on shaft 14 and carrying a changeable upper jaw 16 with an upper part 17, legs 18 and cutting edges 20 towards one attached to jaw 23, the edges 20 pass either side of the conductor or conductors of the cable and rupture the sheathing parallel to groove 24 and the axis of the cable by a combined piercing, shearing and forming action. Groove 24 may be V-shaped or semicircular and interchangeable jaw pieces allow one tool to be used for cables of varying sizes and materials. Optionally, the jaws may be of identical construction with co-operating opposed cutting edges. Alternative designs of cutter with straight, bevelled and curved edges are described and a bar may be attached to the lower jaw to pass between legs 18 over the cable and free it from them when the jaws are opened.
Patent GB-464189-A (GB)
Abstract: 464,189. High-frequency lines. SIEMENS & HALSKE AKT.-GES. Aug. 25, 1936, No. 23339. Convention date, Sept. 27, 1935. [Class 40 (iv)] [Also in Group XXXVI] In order to minimize reflection effects in a high-frequency line, the impedance of a manufactured length is rendered uniform by measuring the impedance progressively and compensating for fluctuations. In practice it is sometimes sufficient to compensate for fluctuations of mutual capacity. The measuring device is preferably connected to the starting end of the manufactured length, and the portions of the conductors not yet combined into the cable as well as the storage drums and other machine parts are screened or otherwise prevented from influencing the measurements. The measurements are made for the whole frequency band coming in question. The compensation may be effected by increasing the quantity of insulating material per unit length, e.g. by reducing the pitch of the tape wound on the conductors or by inserting extra insulating material, or by varying the diameter of the outer conductor in the case of a concentric cable or of the sheath in the case of a stranded cable by means of pressure rolls or by passing the cable through an adjustable nipple. The inductance may be varied by additional magnetic material in the field of the conductors.

Patent GB-1089275-A (GB)
Title: Process for obtaining naphthoquinone
IPC: C07C46/10
Filed: 1964-11-19
Abstract: Naphthoquinone is separated from a hot gas current-formed by the catalytic oxidation of naphthalene-which contains also phthalic anhydride and naphthalene, by contacting and cooling the gas current with water or aq. phthalic acid solution at 30-70 DEG  C., whereby the naphthalene is mainly retained in the gas current and the naphthoquinone precipitate is isolated from the aq. phase containing phthalic acid.  The naphthoquinone is freed from admixed naphthalene by blowing an aq. suspension with steam-saturated air.  Phthalic acid may be isolated by passing the aq. phase over active carbon saturated with naphthoquinone, cooling, removing precipitated quinone, passing over fresh active carbon, and again cooling.

Title: Handling beam-leading devices
IPC: H01L21/00
Filed: 1970-10-06
Abstract: 1325016 Welding by pressure WESTERN ELECTRIC CO Inc 6 Oct 1970 [7 Oct 1969] 47392/70 Heading B3R [Also in Division H1] An apparatus for handling beam lead devices comprises a tool having a vacuum pick-up head provided with electrical terminals between which a heating current pulse can be passed. As described the head (Fig. 2) consists of a conductive block 14 of titanium carbide welded between platinum strips 18, 19 which in turn are welded to nickel terminal lugs 20, 21 and is held in a clamp (Fig. 3, not shown). A bore 17 or supply of vacuum and gas under pressure extends through the block to a chamber 14a for the semi-conductor body, the edges 14b of which are rendered insulating by oxidation. In operation an X-Y table carrying a sapphire plate to which the beam lead devices are attached during manufacture by wax is moved to locate a device under the head. The head is lowered to engage the device and heated by a 1 second 100 amp. current pulse to locally melt the wax and tack bond the beam leads to the engaging edges 14b of the head. The applied vacuum helps to hold the device as the head is raised and moved to a testing station. After testing the head carries the device on the instructions of a control circuit linked to the testing circuit either to a reject bin where it is blown off, if defective, or to a bonding or storage station as required. On return of the head to the starting position the XY table is indexed to locate another device beneath it and the process repeated. At the bonding station the head presses the beam leads against conductive tracks on a substrate and a current pulse is passed to effect a bond, which may if desired be consolidated in a further step. In the bonding process the head may be rocked so as to contact the beam leads one at a time. At the storage station devices are pressed into wax on a carrier and the head heated and cooled to fix the device prior to withdrawal of the head, or simply pressed on to a tacky layer on the carrier. At the testing station the beam leads engage printed tracks on a compliant substrate, the tracks in turn engaging fingers connected to the test circuit.

Abstract: 963,568. Tape dispensers. BETTER PACKAGES Inc. Dec. 19, 1962 [Dec. 26, 1961; Feb. 2, 1962], No. 47989/62. Heading A4G. On moving switch 172, Fig. 1 downwards from a central position, a solenoid 28, Fig. 2 turns lever 24 clockwise about pivot 32 and through spring 27 and lever 20 pivoted at 22, lifts roller 14 to press tape 13 on to dispensing roller 16 driven by motor 17 via chain gearing 18 the tape issuing between a heating element 20, a coated pressure plate 44 and gum moistening brush 40 whereby sticking is prevented. Lever 24 also lifts guillotine 34 which contacts peg 58 on block 52 pivoted on the dispensing roller spindle 54 so as to lift a feeler 56 out of the path of the tape. The length of tape delivered is set by raising a flat spring 112 and rotating a stop 100 until an attached scale 106 indicates the length at pointer 116, after which the spring is released to allow spring pins 114 to be held in holes 110, so that a clock spring loads a disc 60 against stop 100. When block 52 is raised by the solenoid, a friction wheel 64 engages disc 60 which is then driven through gearing 66, 68 from the dispensing roller 16. When the correct length of tape is dispensed, a spring arm 92 on the disc contacts a switch 96 which stops motor 17 and de-energises solenoid 28, whereupon knife 34 descends and cuts the tape and allows feeler 50 to rest on the tape in an intermediate position, friction wheel 64 being lifted from and allowing disc 60 to be sprung back on to stop 100. When the tape is pulled from the dispenser, feeler 50 falls further and rod 132 on block 52 recloses switch 96 for dispensing the next length of tape. The electric circuit with a holding relay may be conditioned by switch 172 for automatic or manual dispensing of set lengths or for dispensing random lengths. With the length set, the dispensing is started by manuel or foot-operated switch operating a holding circuit, and the dispensing ceases on the set length being delivered. For random dispensing, the tape is delivered whenever a swich is actuated.
