Abstract: 1,243,689. Impregnating corrugated card board. BOISE CASCADE CORP. 27 Sept., 1968 [29 Sept., 1967], No. 46011/68. Heading D1L. An impregnating material, e.g. a resin, silicate solution, glue or paraffin wax, is supplied at one fluted edge of a travelling corrugated cardboard sheet, together with a carrier gas or vapour and the material is drawn through the flutes of the sheet dispersed in the carrier, using suction applied at the opposite edge. Liquid impregnants may travel through in the form of small columns of liquid, passage being assisted by compressed air. The arrangement may be such that impregnation takes place from opposite edges of the sheet successively, each step giving impregnation across only half the width of the sheet. Spray impregnants may be applied from both sides simultaneously, the flutes having been evacuated previously. Solid impregnants should be fusible and the sheet and/or carrier are heated to this end. The impregnant may also be a vapour. To assist maintaining vacuum in the flutes the board liners may be sprayed with liquid, e.g. water or a solution of the impregnant, and the edges may be sealed as they pass through the impregnating station. Several apparatuses are described, all similar to that of Fig. 2, in which impregnating liquid supplied at 9 is drawn under vacuum in small columns 9' through the flutes of sheet 2. Hot compressed air from 10 assists the flow and prevents excess impregnation due to premature hardening. The impregnant is hardened by cold compressed air from 11. In Fig. 12 an edge sealing device accepts the sheet between lips 7 (Fig. 2) of guides 50. The projecting liners 2" of the sheet are bent up by the curve of walls 44' (Fig. 10, not shown) and seal against these walls, a vacuum being drawn via chamber 47. Adjustable sealers 54 are also provided. An impregnant may be sprayed from nozzles 53 of this device.

Title: Improvements in or relating to semi-conductor devices
Inventor: STANISLAS TESZNER

Filed: 1962-12-13
Abstract: 1,010,192. Field-effect transistors. S. TESZNER. Dec. 13, 1962 [Dec. 16, 1961], No. 47059/62. Heading H1K. A field effect transistor comprises two semiconductor zones of N (or P) type interconnected through the meshes of a continuous network of P (or N) type material, with source and drain electrodes connected to the two zones and a gate electrode connected to the network. The meshes, arranged regularly, may be circular, square, rectangular or elliptical in form. A typical device (Fig. 12) is made by first diffusing boron through oxide masking on one face of an N-type silicon wafer 25 to provide a P-type grid 26. This face is then washed and etched to provide a clean surface on which N-type silicon 31 is epitaxially deposited by vacuum evaporation or by dissociation of a gaseous mixture of chlorides of silicon and phosphorus. After attaching electrodes 29, 30 the device is electrolytically etched to expose the edges of the grid to which an electrode 32 is then soldered. If oxide masking is provided on a peripheral strip of the wafer face before the deposition step this may subsequently be readily removed to expose the edge of the grid. To make a two-grid device the masking, diffusion and deposition steps are performed on both wafer faces and electrodes then attached as above. An alternative method of manufacture is first to form N+ layers on both faces of the wafer by impurity diffusion and then to diffuse boron through oxide masking to provide P-type grids under each N + layer. The concentration of boron in the diffusion source is chosen so that none of the N+ layer is converted to P-type in this process. Electrodes are attached to the outer N+ layers and to the P-type grids as above. A one grid device (Fig. 17) may also be formed by confining the masking and boron diffusion to one wafer face. In either case if a peripheral strip of the wafer face or faces is masked during the donor diffusion but not in the boron diffusion the grid extends to the wafer face where an electrode may be directly attached to it. If the drain electrode is required to be ohmic an antimony-gold solder is used to attach it. The dimensions and electrical characteristics of typical devices are given and various modes of operation suggested.

Abstract: 1,137,778. Detecting faults. INTERNATIONAL BUSINESS MACHINES CORP. 24 Oct., 1966 [3 Nov., 1965], No. 47520/66. Heading G4A. In data processing apparatus, a unit formed of a number of intercooperating. blocks is tested by applying a sequence of signal patterns to the unit and monitoring the corresponding outputs, the position in the sequence of an invalid output identifying the location of a faulty block, the first signals of the sequence testing reset mechanisms in the unit. Faulty circuit cards in an input channel unit linking an input device and a computer are located under computer programme control by supplying a series of sequences of test signal patterns to the channel unit to simulate data and control signals which it could normally receive. The outputs of two data buffer registers and various control flip-flops in the channel unit, produced in response to the last pattern of each sequence, are passed to the computer which compares them with stored patterns to determine the presence and location of any fault. Only if no fault is detected as a result of a given sequence of test patterns is the next sequence of test patterns applied. The first few sequences of the series are used for testing reset circuitry in the channel unit, and corresponding bits of all the output patterns therefrom are effectively ORed together before comparison. Output channel units and other input channel units can be similarly tested. The test patterns may originate from manual switches. The output patterns may be displayed on lamps or printed out, and the comparison to detect faults may be done by the operator.
