Title: Automatic slice processing
IPC: B23Q41/06
Filed: 1970-07-17
Abstract: 1314590 Programmed control TEXAS INSTRUMENTS Inc 17 July 1970 [29 July 1969] 34772/70 Headings G3N [Also in Division H1] Semi-conductor slices are transported individually and in a predetermined order between serially arranged processing stations, the transport and operations performed at the stations being controlled by a computer. In the embodiment each slice is processed to form an array of planar integrated circuits by standard etching, slice inverting, photo-resist masking etching and impurity deposition and diffusion steps. Each station is self-contained to permit rapid replacement and stations performing similar operations are inter-changeable. The computer is controlled by a deck of instruction cards any of which can be replaced to alter the programme to eliminate faults or introduce improvements in processing. Each slice has binary coded notches at its edge to enable it to be identified by the computer at various inspection stations where it is viewed from various angles and if unsatisfactory fed to a reject magazine. If the slices arrive out of sequence the computer stops the process. Transport is be means of an air track consisting of a linear channel with a series of small apertures along its central axis fed with compressed air. At the cleaning and photo-resist applying stations the slices are held by a vacuum nozzle and spun over a jet of suitable fluid. Duration of the etching stops is controlled by having a series of ramps down which slices can be directed by the computer to points spaced along the bath from which they proceed at a fixed speed to the end of the bath. There are parallel pairs of impurity deposition and diffusion furnaces to allow replacement or repair while the process continues. At the furnace entrances slices are transferred in pairs by vacuum pick-ups to quartz boats. At the exit they are removed and the boats recirculated.

Title: Improvements in pulse modulation detectors
IPC: H03K9/06
Filed: 1945-12-21
Abstract: 605,310. Pulse modulation. PHILLCO PRODUCTS, Inc. Dec. 21, 1945; No. 34813. Convention date, Dec. 21, 1944. [Class 40 (v)] A pulse repetition frequency modulated signal detector comprises a limiter, a pulse-width discriminator, means for producing equal amplitude, equal duration signals spaced in accordance with received signals exceeding a predetermined duration and integrating means to produce signals of amplitude proportional to the intervals between the equal duration signals which contain the original modulation. The output of the I.F. stages is fed to a diode detector 10, which applies pulses to a grid limiter 11. The values of the condenser 13 and resistor 12 in the output circuit of the limiter 11 are adjusted so that pulses of less than a predetermined duration do not build up sufficiently to cause the pentode 14 to draw current, and thus,trigger the multi-vibrator 16, 17. The equal amplitude, equal duration output pulses from the multi-vibrator are applied to the grid of a pentode 21, which is normally biassed beyond cut-off, thus allowing condenser 22 to discharge. In the interval between the pulses, condenser 22 charges up through resistance 23, to a voltage proportional to the interval between the input pulses. This voltage is amplified by valve 24 and fed to audio filter 25, to produce the original modulating signals.

Title: Improved apparatus for generating nuclear fission products
Inventor: HARLEN FRANK
IPC: G21G1/08
Filed: 1957-11-14
Abstract: 915,861. Producing radioactive substances. DOWTY ELECTRICS Ltd. Feb. 13, 1959 [Nov. 14, 1957], No. 35466/57. Class 39 (4). Apparatus for generating nuclear fission products comprises a container having gas inlet and outlet passages, a neutron source disposed within the container and immediately surrounded by a moderator and a surface or a plurality of spaced surfaces disposed around the moderator, the surface or surfaces being coated with a thin layer containing uranium and the distance between the surface and the container or between adjacent surfaces being comparable with the mean free path of the fission products in the gas when in use so that most of the fission products emitted by the uranium as a result of neutron bombardment remain in the gas stream. The apparatus is designed to simulate in detection instruments the contaminated gas flow in a nuclear reactor having a broken fuel element container. The apparatus shown in Fig. 2 comprises a steel pressure vessel provided with a central closed tube 4 in which an antimonyberyllium neutron source 5 may be positioned between lead plugs 6. In the neighbourhood of the neutron source the tube 4 is surrounded by a moderator cylinder 13 which is preferably of beryllium but may be wholly or partly of paraffin wax. A high-pressure annular chamber 14 provided with gas inlet and outlet pipes 15, 16 surrounds the cylinder 13 and contains aluminium plates (not shown) of semi-circular crosssection coated on their convex surfaces with uranium oxide. Surrounding the chamber 14 is a further annular space provided with gas inlet and outlets 24, 25 and containing aluminium tubes 19 filled with paraffin wax and coated on their outsides with uranium oxide. The spaces above, below, and around this annular space are filled with paraffin wax 11. Gas takes a comparatively long time to traverse the annular space and the fission product contamination is not closely dependent on pressure so that it is useful for comparative work, but the fission product distribution differs from that in a reactor. The transit time of gas through the inner chamber 14 can be short and comparable with the transit time of a coolant through a reactor, so that the fission product distribution is similar to that in a reactor.

Class 98(2). The material comprises a transparent base with a carrier layer comprising polyvinyl alkyl ether-maleic anhydride in admixture with a different resinous material or polymer, and a light sensitive layer comprising a diazo oxide coated on the carrier layer. Thirteen examples use vinyl methyl ether-maleic anhydride copolymer (PVM/MA) together with a variety of other materials as carrier layer and after sensitisation are exposed by reflex, in some instances with interposition of a screen, and developed or processed with solvent to make offset printing plates or else intermediates for subsequent diazo copies; thus in Example I a cellulose acetate film is lacquered with PVM/MA together with cellulose acetate in a solvent mixture, dried, coated with a solution of low molecular weight polyvinyl acetate together with N- dehydroabietyl - 6-diazo-5(6)-oxo-1-naphthalene sulphonamide, dried again, reflex exposed, developed in aqueous monoethanolamine with ethylene glycol, raised in water and finally damped as in lithographic procedure. In Example II a similarly prepared article is hand-inked for use as an intermediate. Example III describes the use of a vinyl acetate /crotonic acid copolymer along with the PVM/MA on a polystyrene base for sensitisation by the diazo mixture of Example I to result in an offset plate, and Example IV cellulose acetate therewith on transparentised rag paper for production of an intermediate. In the screen procedure Example VII uses the re-usable screens of Specification 626,501 or 630,874 with the sensitive material of Example I, Example XI similarly uses the sensitive material of Example III, Example XII what is described as an "electroformed mesh" screen of 1000 lines per inch, and Example XIII a screen laminated to the sensitive material of Example I, all of these for offset plate production. Numerous other bases, PVM/MA type polymers and resinous materials for mixing therewith, solvents, sensitisers and so on are listed.
