Title: Segmented asynchronous operation of an automated assembly line
IPC: G05B19/02
Filed: 1972-04-17
Abstract: 1383093 Automatic control of assembly. TEXAS INSTRUMENTS INC 17 April 1972 [16 April 1971] 17699/72 Heading G3N A group of work stations of an assembly line carry out independently and asynchronous operations under the supervision of a computer having a programme whereby the status of each work-station is sequentially checked to determine whether the execution of an operating programme for a work-station is required. As shown, Fig 1, a multi work station machine for operating on semi-conductor slice comprises a bed section 1002 along which the slice 1003 is transferred by a pneumatic transport mechanism 1006. At the queuing-stations 1000, 1001 the workpiece carrier is sensed by photocells 1004 and retained by brakes 1005. The workpiece is moved into the work-station 2008 on an extension 1008, by the transport mechanism 1006 and braked in a carrier 1010. The carrier is positioned with respect to the extension 1008 by a platform 1007 elevated by a screwdrive. The incremental position of the elevator is sensed by a photo-cell 1015, between limits sensed by photo-cells 1013, 1014. The slice is inserted in grooves 1016 of the carrier. The operation of a plurality of these machines are controlled by one or more bit-pusher computers 10, Fig 2, and a general-purpose computer 11. The machines 12 are grouped together as a module 13 and a number of modules are controlled by each bit-pusher computer 10. The computers 10 operate without continuous communication with the computer 11 but are serviced on request, through an adapter 15 which routinely provides for alarm and other message traffic and initial start-up of each computer 10. The computer 11 also performs programme assembly for the computers 10 from card reader 18, printer 19 and typewriter 20, and has longterm disc storage 16 and tape storage 17.

Title: Improvements in or relating to counting and like circuits
Inventor: WOLFENDALE ERIC
IPC: H03K23/00
Filed: 1953-06-26
Abstract: 739,109. Electronic counting - apparatus. MULLARD RADIO VALVE CO., Ltd. May 11, 1954 [June 26, 1953], No. 17799/53. Class 106 (1). [Also in Group XL (c)] A digital counter comprises a plurality of bi-stable single-transistor stages connected in succession, a plurality of rectifiers each connecting the collector of one stage to the emitter of the succeeding stage, means for conveying input pulses simultaneously to the emitter connections of said stages, and a plurality of collector impedances, one for each stage so arranged that when a particular stage is in the "off" " state the rectifier connecting it to the succeeding stage is biased in its reverse direction, thus preventing input pulses from reaching the said succeeding stage, while when a particular stage is in the " on " condition the increased collector current reduces said biasing sufficiently to permit a pulse to pass the rectifier and trigger the succeeding stage from its " off " to its " on " state. In this way successive input pulses successively trigger each stage from its " off " to its " on " state. Each stage. for example stage 2, consists of a point-contact transistor 11 arranged to have two stable states, an " off " state in which a small negative current flows from the emitter via a diode 13, which serves both to limit the negative voltage on the emitter to - Ee volts and as an emitter load, battery Ee, secondary winding of a transformer T feedback resistance 12 and back to the base of the transistor, and in which a small positive collector current flows, and an " on " state in which relatively large positive currents flow in both the emitter and collector circuits. During the " off " state the emitter potential of each stage is lower than the collector potential, so that the diode (18) connecting two adjacent stages (stages 2 and 3) is biased in its reverse state when both stages are " off " and is in its forward state when the first of the two adjacent stages (stage 2) is " on." Thus if stages 1 and 2 are " on " and the other stages are off a positive input pulse applied to each stage via condensers 6, can only affect stage 3, since that is the only stage having a conducting input diode 18. Successive pulses therefore successively trigger each stage to its " on " condition until the last stage is reached which differs from the preceding stages in that a condenser 103 forms the emitter load and in that the stage has only one stable state, namely " off," and which functions as a pulse regenerator, producing a positive output pulse via a condenser 105 which is fed back, via transformer T, to each preceding stage which is consequentially triggered to its " off " state. In a modification the first stage of the chain is preceded by a diode 08 suitably biased to simulate an imaginary preceding stage in its " on " state, and thus ensuring uniform sensitivity for each stage.

Filed: 1965-04-28
Abstract: 1,049,546. Container closures. AMERICAN FLANGE & MANUFACTURING CO. Inc. April 28, 1965 [May 4, 1964], No. 17850/65. Heading B8T. A closure for a can, bottle, jar &c. consists of a resilient plastics lid 4, enveloped by a metal sealing cap 5 to which a gripping tab 25 is integrally attached. An edge 15 of the lid 4 snaps over an upwardly diverging rim 2, Fig. 4 (not shown), of the can &c. and a sealing member 30, Fig. 7 (not shown), and an anvil 31 compress the metal cap 5 about the rim 2 so that the lid 4 forms a gasket between the metal cap and the rim. A lower portion 32 of the cap skirt 23 is pressed firmly against the can wall. The metal cap 5 is removed by pulling the tab 25, whereupon the cap tears along score lines 27, Fig. 1 (not shown), extending across the top the cap. Access to the can contents is obtained by prising the edge 15 of the.lid 4 over the rim 2. In a modification. Figs. 9, 10 (not shown), the metal sealing cap is in the form of a U-shaped, annulus 35 which clamps the lid 4 about the rim 2. A gripping tab 40 lies flat on the lid 4 in the centre of the annulus, score lines 42 enabling the annulus to be destructively removed. The closure may be applied to a can with an inwardly or outwardly curled-over rim. In a second modification, Fig. 13, (not shown), the closure is applied to a bottle having a beaded mouth 55. Since the bottle neck is sufficiently rigid, no back-up anvil 31 is needed with the sealing member 30 and so the centre portion of the closure is not recessed.

Title: Improvements in or relating to semiconductor devices
IPC: H01L21/00
Filed: 1960-05-24
Abstract: 917,645. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 24, 1960 [June 23, 1959], No. 18224/60. Class 37. In a PNPN semi-conductor switching device, the first three regions form a transistor with a current gain of between 0.2 and 0.4 and the second, third and fourth form a second transistor with a current gain of between 0.6 and 0.9; the overall gain is greater than unity. In Fig. 1, P-zone 13, N-zone 12 and P-body 14 form the first transistor section and NPN zones 12, 14 and 16 respectively form the second. The low current gain of the first section tends to provide a high-voltage breakdown while the large current gain of the second enhances current flow through the device when switched. Ohmic connections 18, 19 and 20 are made to zones 13, 14 and 16, respectively. Fig. 3 shows a circuit comprising the device which is maintained non- conducting by a negative bias to zone 14 from battery 30. When a positive pulse is provided from generator 33, the device conducts to operate relay 32. The zone structure may be produced providing N-type layers 12 and 16 on P-type body 16 by diffusion, alloying leadantimony dot 23 to zone 16 to provide an ohmic contact thereto, alloying dot 21 of leadgallium alloy and indium dot 22 simultaneously to provide P-type zone 13 on N-type layer 12 and ohmic contacts to the P-type zone 13 and P-type zone 14. In a modification, a dot comprising lead antimony and gallium or lead, antimony and indium is used to provide P and N regions in one post-alloy diffusion operation. The alloy may consist of 0.6 to 1% of antimony, 0.0025 to 0.0075% of gallium, the balance being lead.

Title: Improvements in or relating to the manufacture of transparent films
IPC: C08L5/04
Filed: 1939-06-23
Abstract: 530,889. Films. ROSE, R. C., and CEFOIL, Ltd. June 23, 1939, No. 18408. [Class 2 (ii)] Transparent alginic films are obtained by causing a solution of an alginic compound to flow through a slot to form a liquid film, coagulating the film and, at the same time or subsequently, subjecting the undried film to the action of an acid so as to induce substantial syneresis, i.e. expulsion of water from the film, and finally drying the film. The coagulating bath may be strongly acidic so as to effect coagulation and syneresis simultaneously, or syneresis may be effected in a subsequent bath containing sulphuric acid or a solution of calcium chloride acidified with hydrochloric acid or other acid. The process may be conducted so that the production of the film is completed under slightly acid conditions, the film thus containing free alginic acid. The film may be subjected to the syneresis treatment and dried under conditions which allow three-dimensional contraction. The alginate material used may be such that it has a viscosity of not less than 10 centipoises in a 1 per cent. solution in water at 15‹C. In an example, a solution of sodium alginate is extruded through a slot into a solution of calcium chloride and the film is subjected to syneresis and allowed to contract in a bath of calcium chloride containing 0.2 normal HCl. It is further converted to alginic acid by a solution of HCl, washed and dried. When sulphuric acid is used for the syneresis a strength of 0.1-0.5 N may be used. When sulphuric acid is used in the coagulating bath and simultaneous syneresis is desired, a strength of 0.5-2.0 N may be used. Instead of converting the film into alginic acid or calcium alginate it may be converted into another salt or an amine derivative of alginic acid. As shown in Fig. 1, sodium alginate solution passes from tank 11 to storage tank 12, and thence to hopper 13. It then issues from an adjustable slot as a liquid film 16. This is received on an endless band 17 running round rollers 18 in a coagulating bath 19. The film is stripped from the band and passed successively through a synerizing bath 21 containing calcium chloride and hydrochloric acid, a conversion bath 25 containing calcium acetate, or an acid such as sulphuric acid, or calcium chloride solution rendered alkaline with ammonia, a washing bath containing water, and a plasticizing bath containing e.g. glycerol. It then passes into a drying chamber where it passes over drying rollers rotating at progressively lower speeds so as to allow for shrinkage. Contraction in the syneresis bath 21 is permitted by rotating rollers 24 at a lower speed than roller 20. As shown in Fig. 2, the alginate solution is extruded from the hopper 13 and the film is received on and forwarded by a system of rollers 31 immersed in a bath 19 containing calcium chloride and strong mineral acid whereby coagulation and syneresis take place simultaneously. Specification 492,264 is referred to.
