Inventor: HARRISON HENRY MILBURN
IPC: G11B15/38
Filed: 1958-11-26
Abstract: 930,665. Feeding webs. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 26, 1959 [Nov. 26, 1958], No. 38034/58. Class 100 (1). [Also in Group XXXVIII] An apparatus for feeding a web, especially magnetic tape, in either of two directions comprises a pair of vacuum capstan rollers 6, 8, means for continuously rotating the capstan rollers in opposite directions, means for selectively applying high suction to the rollers so as to feed the web in a direction dependent on the roller to which high suction is applied, and means for releasing the high suction from the roller effecting feed and for momentarily applying high suction to the other roller so that a braking force is applied to the travelling web. As shown, tape 2 is fed into a bin 5 by a vacuum capstan roller 4. Capstan rollers 6, 8 rotate in opposite directions to feed the tape 2 in either direction across a perforated surface 7 connected to suction past a transducer or transducers (not shown). The rollers 6 and 8 each have a high suction chamber 15 and a low suction chamber 16 connected by a valve 17 operable to couple the chamber to high or low suction or in an intermediate position to connect the chambers 15 and 16. The tape is fed in the direction of rotation of the roller connected to high suction. When it is required to arrest the tape, valve 17 of the roller 6 or 8 feeding the tape is actuated so that high suction to that roller is terminated. The low suction chamber 16 of that roller is momentarily connected to the high suction chamber 15 during the operation of the valve 17, thus creating a decrease in pressure in a conduit 20 connected to the chamber 16 of the other vacuum capstan roller 6 or 8 to cause braking of the tape. The tape may be guided into the bins 5 and 9 by stepped plates and the tape caused to form ripples by air blasts directed inwardly of the bins, thereby preventing long loops being formed in the middle of the bin. Specifications 918,691 and 930,664 are referred to.

Title: Method of fabricating spaced electrically-insulated through- connection in a conductive sheet
IPC: H05K3/46
Filed: 1973-08-16
Abstract: 1443338 Making multi-wafer circuit structures BUNKER RAMO CORP 16 Aug 1973 [5 Sept 1972] 38714/73 Heading B3A [Also in Division H1] A method of making a plurality of spaced, electrically insulated through-connections 136 in a predetermined pattern, in a conductive sheet 122 for use in a multi-wafer electrical circuit structure (10), Fig. 1, (not shown) comprises stamping one surface 124 of the sheet to form a plurality of recesses 134 which define through-connection segments arranged in the predetermined pattern, affixing dielectric material 144 in the recesses, and removing a layer from the opposite surface 126 to isolate electrically the so-formed connections 136 from the sheet, the dielectric material 144 serving to support the through-connections. The layer is removed from the surface 126 of the sheet, which may be of copper or beryllium copper, either by sanding or by chemical etching. After the layer has been removed conductor segments 140 are finally shaped by etching recesses into the surface 126, which recesses are filled with dielectric material and sanded flat. The conductor segments 140 constitute X- and Y-axis conductors in the multiwafer structure and the connections 136 form Z-axis slugs to interconnect adjacent wafers. Malleable contacts 96 are provided on both ends of the Z-axis slugs on connector wafers 102, Fig. 9, the contacts being more ductile than the slugs so that they are deformed by slugs in adjacent wafers when the wafer stack is placed under pressure on assembly thereby forming good electrical interconnections. Similar contacts are provided on the surface of the wafer to provide earth interconnection. The malleable contacts may be formed by selective chemical etching and electroplating techniques. Active devices 40 are mounted on a component wafer 100 and conductive material 60, e.g. solder, interconnects a terminal point 56 to a terminal on the device. A connector wafer 102 is placed on the wafer 100 and a plurality of filler wafers 106 are stacked above the wafer 102. The wafers 106 can be fused together or they can be interconnected by compression of the stack when the multiwafer structure is assembled in a housing 20, Fig. 2. In the latter case only alternate wafers are provided with malleable contacts. The wafer stack is mounted between a connector block 24 and a pressure plate 26 and is held in compression by a resilient pressure pad bearing on the plate 26. The wafers are aligned by keyways  (38), Fig. 1 (not shown), which mate with keys 39 formed in the housing. Some of the wafers are formed with fingers 37 which contact the housing walls to provide heat transfer paths and the connector block 24 contains output terminal pins 24a coupled to the stack by means of an output connector wafer 16a.

Abstract: 1480508 Missile guidance systems FERRANTI Ltd 5 Sept 1975 [6 Sept 1974] 38949/74 Heading H4D A missile guidance system includes a laser 1 mounted at a guidance station for the transmission of pulses of laser radiation 2 towards a target, means on the missile for reflecting a portion of the radiation back to the station, means (Fig. 4) carried in the missile and responsive to control instructions conveyed to it by the radiation, and means (Fig. 2) at the station responsive to radiation reflected by the missile to cause the laser to transmit the necessary instructions, which are in the form of pulses (Fig. 3, not shown) each representing an instruction the nature of which is indicated by the time lapse between the pulse and the immediately preceding one. Reflected radiation is sensed by a quadrant detector 4 whose outputs cause a unit 9 to transmit to an encoder 10 signals representing the missile position in elevation and azimuth relative to the axis of symmetry of the detector. When the output of a counter 11 (reset at the last laser pulse) coincides with the output of encoder 10, a comparator 13 causes laser 1 to operate and the counter to be reset. In the receiver, a similar counter 32 begins counting on receipt of a pulse; receipt of the next pulse causes its count to be transferred to a decoder 31 which produces control signals E1, A2 together with "increase attenuation" and "decrease attenuation" signals 1A, DA as required to control the rate of response of the missile. The transmitted and reflected pulses may be used to measure the distance of the missile from the guidance station.

Microfilm cards stored in a magazine 9 are fed seriatim by roller pairs 46, 48 to the cardhandling device 11 where they are positioned for movement past a scanning slit and illuminated so as to project an image of the scanned area through an objective 12 on to a xerographic drum (not shown). The card is delivered from rollers 48 on to a carriage 78, which at this stage is aligned with the rollers. The floor of the carriage has a flat glass insert 97 on which the card is laid. A pressure plate 101 having an aperture 89 is carried by pivoted arms 98, 99 mounted on the backing plate 80 of carriage 78. The plate 101 has flanged side edges 92, 93 which guide the card into position as it is received from rollers 48. A front plate 107 pivoted on a stud 108 abuts against the front edge of the card after it has been delivered on to the glass plate 97. The sequence of operations is controlled automatically by two cams 104, 116 mounted on a shaft 32. Arm 98 extends downwards and has at its lower end a wheel 103 which follows cam 104; plate 107 is connected by a linkage to a wheel 115 which follows cam 116. In operation, the high dwell of cam 116 causes plate 107 to rock anti-clockwise so as to allow unimpeded entry of a card from rollers 48. At the same time, the first high dwell of cam 104 causes plate 101 to be pivoted upwards sufficiently to allow a pair of ejector pins 120, actuated by a crank 124 following another cam (not shown) on shaft 32, to push out the card in the device. (It is then gripped between rollers 48 and 62, and delivered to'a collector magazine 68.) The second high dwell of cam 104 now causes plate 101 to be raised to its maximum height for accepting the card delivered from the magazine 9. After the delivery of the card on to glass plate 97, front plate 107 is rocked clockwise to position it accurately thereon, and plate 101 lowered to hold it firmly. The whole device 11 is then moved laterally along a shaft 84, so that the illuminated film area is traversed past the scanning slit, after which it is moved back again, and the cycle recommenced.
