Title: Improvements in or relating to crystal triodes and semi-conductor materials therefor
Inventor: WHITE CHARLES DE BOISMAISON
IPC: H01L21/3063
Filed: 1949-04-01
Abstract: 665,867. Making germanium ingots; powder metallurgy. STANDARD TELEPHONES & CABLES, Ltd. March 31, 1950 [April 1, 1949], No. 8905/49. Drawings to Specification. Classes 83 (ii) and 83 (iv). [Also in Group XXXIX] An electric amplifying device comprises a semi-conducting body composed of uniformly distributed, small aggregates of atoms each of which aggregate has either P- or N-type rectification properties. The material is such that over any cross-section a random distribution of minute areas each providing either N- or P-type rectification exits. This results in P-type areas having, a high rectification ratio, which is not the case for homogeneous P-type crystals. One method of producing a semi-conductor of this type consists of heating germanium dioxide in pure dry hydrogen to produce pure germanium which is placed in graphite crucibles and remelted at low pressure in the presence of small amounts of oxygen, nitrogen, and water vapour. The proper amounts of gases to be added, which provide both donor and acceptor impurities, is determined experimentally in each case. The ingot is then rapidly cooled to provide the desired material. Alternatively the ingot may be remelted as above, but without the addition of the impurities, and the remelted ingot is continuously stirred while cooling, which has the effect of producing positive and negative ions. A third method consists in sintering a mixture of finely-ground homogeneous N-type and finely-ground homogeneous P-type germanium.

Title: Improvements in or relating to delivery apparatus for printing and like machines
IPC: B65H29/62
Filed: 1942-07-02
Abstract: 559,854. Printing-machines. GOSS PRINTING PRESS CO., Ltd., and EDWARDS, J. H. July 2, 1942, No. 9170. [Class 100 (i)] A delivery apparatus for use in connection with machines for printing late news of the kind in which the printing takes place continuously and one printing- cylinder is out of action while a second is in operation is so constructed that sheets which are spoilt while changing one cylinder for another are either displaced on the delivery belt so that they can be discarded or they are directed by sheet guides 35, Fig. 5, to a separate delivery device. As applied to a machine in which the sheets are normally delivered in counted batches on a band 14 by an S-fly 10 co-operating with a kicker 15 which displaces a sheet at the end of a given number of sheets, a second kicker 21 is used which can be brought into operation by the mechanism which changes the "late news" cylinders. This trip mechanism acts by causing the energization of a solenoid 25 the armature 24 of which is connected by a pin-and-slot mechanism 28, 27 to the lever of the kicker 21. A lag in the timing of the action of the kicker 21 is provided for by using an electromagnetic relay, or by using a dash-pot in connection with the armature 24, or by the pin-and-slot mechanism. This ensures that the kicker 21 causes displacement on the band 14 of all of the spoilt copies and no unspoilt ones. The lag can also be produced by a variably-timed friction drive. As shown in Fig. 5, the switch 35 is pivoted at 39 and actuated by an electromagnet 45 acting upon a spring-controlled rod 42 formed with collars 47, 48 for limiting the movement in either direction. The mechanism for tripping the "late news" cylinders may be arranged to trip the counting mechanism which normally controls the delivery in counted batches. A time lag is also provided in this mechanism. Specification 559,853 is referred to.

Title: Improvements in or relating to methods of and/or means for finding average temperature over a period of time
IPC: G01K1/02
Filed: 1968-02-27
Abstract: 1,208,653. Measuring temperature electrically: electrolytic meters. NEW ZEALAND GOVERNMENT PROPERTY CORP. Feb. 27, 1968 [March 2, 1967], No.9304/68. Headings G1N and G1Q. The average temperature over a known length of time of a space or article is determined by measuring the mass of metal deposited on or removed from one of a pair of electrodes immersed in an electrolyte at the temperature of the space or article and connected to a constant voltage D.C. supply, the average current flowing through the cell being proportional to the mass deposited or removed divided by the length of time over which the measurement is made, and is proportional to the average temperature during this time. As shown, the cell comprises two copper electrodes 10, 11, Fig. 2, closing the ends of a transparent plastics tube 17 filled with copper sulphate solution. Glycol may be added to the solution to reduce its freezing point. The electrodes are provided with terminals for connection to, e.g., a mercury battery (4), Fig. 1 (not shown), providing a constant voltage. A plug 19 is provided in the tube to lessen the effects of polarization of the electrodes, the gas bubbles being trapped in depressions 21, 22, passageways 20 providing connections between the electrodes. The mass of metal removed from the anode and deposited on the cathode may be measured by direct weighing of the anode or cathode before and after measurement. Alternatively the change in the centre of gravity of the cell may be determined e.g. by observing the period of a pendulum, whose bob is formed by the cell, before and after measurement. Alternatively the anode may be made in the form of a wedge, the mass of metal removed being a function of the remaining length of the wedge. Electrically this measurement may be carried out by integrating the reverse current required to return the cell to its original state. To facilitate this method, the cathode may be made of carbon, so that during measurement copper is deposited on the carbon. Reversal of the current to return the cell to its original state is then carried out until a sudden rise of resistance in the circuit indicates that the copper has all been removed from the carbon cathode.

Title: Glazed refractory bodies
IPC: C04B35/08
Filed: 1965-03-04
Abstract: A fired beryllia ceramic film has on at least one surface a glaze coating which does not soften below 700 DEG  C.  The film is not more than 0.1 inch thick and has a camber less than 0.004 inch/inch in any direction in the plane of the film.  The coating is uniform with a weight of 0.08-0.12 g./in,2, and is substantially free of the oxides of K and Na.  The surface of the coating is so smooth as to give a reading of not more than 1.0 micro inch (Centre Line Average) when measured with a "Tallysurf" (Registered Trade Mark) tester.  The coefficient of thermal expansion of the coating is sufficiently analogous to that of the beryllia film and the adherence is so firm, that after a thermal shock test in which the article is heated to 550 DEG  C., cooled to 23 DEG  C. in 20 minutes, immersed in liquid nitrogen at -210 DEG  C., and then allowed to come to equilibrium at room temperature, no visible defects in the coating or article develop.  Tantalum may be sputtered on the glazed film for production of a component for an electric circuit.  The beryllia film contains at least 98% BeO by weight, and may also contain, e.g. SiO2, manganese oxide and alkaline earth oxides. An example of the composition is in per cent by wt., BeO, 99.5; MgO, 0.40; Al2O3, 0.075; SiO2, 0.025.  Raw material is ball-milled with an organic binder, and the slip is then de-aired and applied to a smooth carrier, e.g. "Cellophane" (Registered Trade Mark) as a coating of uniform thickness and density.  Volatile vehicle is then removed, e.g. by heated forced air drying.  The green film may then be stamped with score lines or holes for separation or perforation of the film after glazing. It is then fired at a maximum temperature of 1550 DEG C., and is thereafter cleaned.  The glaze frit may comprise, by weight: PbO,20-50%; SiO2,30-60% and 10-40% of other ingredients, being: bivalent metal oxide, e.g. alkaline earth oxide, at least 5%; B2O3, at least 3%; oxides of Na and K, not more than 5% in total.  To this frit may be added, e.g. 2-8% kaolin based on kaolin and frit. Based on the weight of inorganic solids, 55% water, 3% glycerine and 1.5% methyl cellulose are admixed, and the whole milled to form a slip, which may be applied, e.g. by spraying.  The article is then air-dried and fired in air at 1020 DEG  C.  The following three frit compositions are exemplified in per cent by weight:  SiO2 40.7/36.3/35.4; B2O3, 11.1/5.9/5.5; Al2O3, 3.5/4.0/4.0; PbO, 31.6/43.1/44.1; CaO, 9.8/10.4/11.0; Na2O, 1.9/-/-; K2O, 1.4/-/-; MgO, -/0.3/-.  Two resulting glaze compositions are:  SiO2 37.6/36.2; B2O3, 5.5/5.4; Al2O3, 6.9/4.3; PbO, 40.0/43.3; CaO, 9.7/10.8; MgO, 0.3/-.
