Title: Improvements in or relating to paints and the like
IPC: C09D193/04
Filed: 1945-09-20
Abstract: A coating composition comprises a dispersion of a water-insoluble saponification product of a mixture of a resin acid and a fatty acid, with or without residual free acid.  The preferred mixture of acids is liquid rosin (tall oil or tallol). The dispersion medium is normally an aqueous liquid containing small amounts of emulsifying agents such as borax, casein and ammonia.  The acid mixture may be employed as such or as a mixture with an organic solvent, e.g., ethyl or methyl alcohol.  The saponifying agent may be an alkaline earth metal oxide or hydroxide, e.g., hydrated lime, and/or a heavy metal oxide, e.g., zinc oxide or hydroxide.  Pigments, e.g., ochre, oxides of iron, whiting and lithopone and fillers, e.g., china clay may be present as may also thinners such as white spirit.  The saponification may precede or follow emulsification.  The composition may be applied particularly to building materials such as concrete and asbestos cement to form a protective layer or as a sub-stratum binder or paint layer.

Title: Device for selective call sending
IPC: H04M1/50
Filed: 1968-05-23
Abstract: 1,208,329. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 23 May, 1968 [30 May, 1967], No. 24691/68. Heading H4K. In a register-sender (e.g. for an operator's keyset) in which directory numbers stored in the register are forwarded as combinations of frequencies selected by a matrix, repeated sending in the event of a group of consecutive identical digits is avoided by sending a special frequency signal for the second, fourth, sixth &c. digits in that group. The arrangement described is incorporated in a device for selectively calling mobile radio receiver stations. One frequency per digit is used with an eleventh frequency used as a repeat signal. The matrix has eleven parallel input conductors, each connectible to a corresponding oscillator supplying the corresponding frequency, and five output conductors orthogonal to the first set and corresponding one to each digit to be sent. The keyset has ten digit keys, each of which when depressed closes two contact pairs. The first pair of contacts of each key are coupled in parallel and advance a sequencing arrangement for each digit entered, while the second pair of contacts of a key connects in series two out of five relays in the register and allotted by the sequencing circuit to store that digit. The two relays thus enabled by a digit each close a set of contacts. The input and output conductors of the matrix are coupled at the cross-points by series combinations of two contact pairs associated with different relays of the set of five relays storing a digit so that only one path is completed, connecting one of the ten digit representing frequencies to one of the output conductors. Each pair of adjacent output conductors is tested by a comparator relay which is enabled by a closed loop path through correisponding cross-points associated with the two output conductors if the corresponding digits are identical and the path has not been interrupted by a contact of the comparator relay associated with the first output conductor of each pair and the previous output conductor. Those comparator relays which are enabled, block the transmission of the digit value indicating frequency on that output conductor and gate the eleventh or repeat frequency into that output. When the digits have been transmitted the apparatus is adapted to send a twelfth spacing frequency and to recycle once to again send the wanted number.

In a push-button operated magnetically held switch, release is effected by energization of a coil 22 surrounding core parts 5 which extend toward each other and are separated by an air gap 6. The armature 9 supports a contact bridge 11 secured to a push-button 12 and when it is moved thereby it bridges upper extensions 7 of two T-shaped yoke and core members 3 each of which is formed of back-to-back identical magnetic parts. A permanent magnet 8 bridges the other two extensions 7 and retains the armature until sufficient current flows in the coil to oppose the permanent magnet flux in the armature which is moved upward by biasing springs 27 acting at diagonally opposite corners thereof. Part of the magnetic circuit may have a low curie-point so that the armature is released on rise of temperature. Contact pairs 14, 15 and 18, 19 are bridged in the two alternative positions of the movable contact bridge 11. The fixed contacts 14, 15, 18, 19 and coil terminals 24, 25 have extensions 20 (Fig. 2, not shown) which project from the switch housing 1, for connection to a printed circuit board.

Abstract: 1,263,626. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 15 May, 1969 [17 June, 1968], No. 24782/69. Heading H1K. A semi-conductor device comprises a plurality of regions having uniform doping levels along their boundaries, so forming abrupt junctions between adjacent regions, the regions comprising two heavily doped regions of opposite conductivity type, one of which is epitaxially deposited, with an interposed lightly doped region which is also epitaxially deposited. An avalanche diode for producing microwave oscillations comprises a heavily doped (N+) substrate 12, of antimony doped silicon, a lightly doped (N-) epitaxially deposited, thin layer 14 and a heavily doped (P + ) epitaxially deposited, thin layer 16, doped with boron. The epitaxial depositions are carried out quickly at a relatively low temperature of 1100‹ C. so as to prevent out diffusion from the substrate. Contact layers 18, 20, 22, 24 are applied sequentially to both sides of the device following photo resist, etching and lapping steps. Thermocompression and ultrasonic bonding may be used to bond the contact layers together. The substrate is finally etched through to produce a plurality of separate devices. A copper heat sink 28 may be bonded to one side of the diode via a gold layer 26. In an alternative embodiment a Read diode, with an intrinsic region formed between the substrate and the lightly doped region may be also constructed using epitaxial deposition.

Title: Process for the production of carbides such as titanium carbide, boron carbide or zirconium carbide
IPC: C01B31/30
Filed: 1955-08-30
Abstract: <PICT:0777013/III/1> Hard carbides are produced from a mixture of carbon and the oxide of the element the carbide of which is to be produced, by electric arc heating in an electric furnace comprising two electrodes capable of up and down movement and a carbon or graphite bridge, each electrode making arcing contact initially with the carbon bridge and then with carbide which builds up on the bridge in the form of two ingots, with little or no formation of liquid, as the reaction proceeds.  The ratio of the cross sectional area of the bridge to the diameter or equivalent diameter of the electrodes may be 2:12.  The applied voltage may be 50-160 volts.  The production of titanium, zirconium and boron carbide, and proportions of carbon to oxide of 1-2 to 1, 0.7-1.5 to 1, and 0.6-1 to 1 respectively are specified.  The oxide may be in the form of ore, e.g. rutile, zircon or baddeleyite. Unconverted or partially converted oxide from a previous operation may be mixed with fresh oxide.  As shown, the furnace comprises two electrodes 80 and an oval-shaped shell 20 supported on a base 66 around an inner container 67 and cooled by sprays of water supplied at inlets 57-60.  A concave layer of fine carbon and pitch is formed in the inner container 67 and refrectory non-electrically conducting oxide material is packed between the container 67 and the shell 20.  A layer of oxide material is then added to a height of ca. 4 inches above the top of container 67. The oxide material may be the same as is used in the reduction process, unconverted or partly converted material from a previous operation or other oxide material, e.g. alumina (in the production of boron carbide).  In a trough in the oxide material is then placed a bridge of graphite or carbon of length equal to the distance between the electrodes.  The furnace is wheeled beneath the electrodes which are then lowered into position.  A layer of mixture to be heated is then placed in the furnace to a depth of 1-3 inches and a current passed through the electrodes.  In operation automatic control mechanism raises and lowers the electrodes, maintaining arcs with a current flow of ca. 8,000 amps., and additional mixture is introduced as carbide is formed. The layer of mixture may be maintained 1-3 inches deep in the area of the electrodes, measured from the bottom of the electrodes.  After completion of a run the electrodes are raised, the furnace wheeled away, allowed to cool while the water spray is maintained, and the shell lifted.  Three phase power may be used instead of single phase power, using three electrodes and a round or trilobed furnace shell.  Specification 747,834 [Group XXXVI] is referred to.
