Abstract: 850,119. Welding by pressure. SIEMENSSCHUCKERTWERKE A.G. April 18, 1958 [April 18, 1957; Dec. 13, 1957], No. 12377/58. Class 83 (4). [Also in Group XXXVI] A connecting conductor is fixed to a metallic electrode of a semi-conductor device by applying a pair of welding electrodes to closely-spaced parts of the conductor where it overlies the electrode and passing a pulse of current between them to weld the conductor to the electrode. In one embodiment, Fig. 1, a silver wire 2 is welded to a gold antimony alloy electrode 1a on a PN junction silicon or germanium body 5 by passing. current between welding electrodes 3 and 4. The two ends of the wire may afterwards be twisted together. In another embodiment a cup-shaped conductor 105 (Fig. 11) is welded over an annular region to the gold antimony electrode 104 on a silicon plate. To effect the welding, current is passed between a pair of coaxial cylindrical electrodes 107, 108 pressed against the bottom of the cup. Such a cupshaped conductor may alternatively be welded to the electrode at a series of spaced points. The points may, for instance, be arranged along the sides of or at the corners of a square, on the periphery of a circle or concentric circles, or along parallel or inter sectinglines, e.g. lines radiating from a point or lines intersecting at right-angles. The various welds may be produced singly, in groups, or all together by using a suitable number of welding electrodes. For example where the points lie on a circle, Fig. 13, the cup-shaped conductor may be provided with concentric ridges 110 notched at intervals for the purpose of locating suitably-shaped welding- electrodes 111, 112. The electrodes are moved around between pairs of adjacent notches to form the welds individually. As an alternative the conductor may be provided with suitablyplaced indentations for locating the welding electrodes, or with pin-shaped projections which co-operate with recessed welding electrodes. A tape-like conductor formed with a square or circular cup-like indentation similar to conductor 105 may be welded to the electrode of a semi-conductor device by processes similar to those described above.

Patent GB-890093-A (GB)
Title: Improvements in or relating to cyanuryl chloride
Filed: 1960-04-08
Abstract: Cyanuryl chloride is prepared by reacting chlorine and hydrocyanic acid in the vapour phase at above atmospheric pressure in the presence of a catalyst substantially until equilibrium is attained. The temperature is preferably between 200 DEG C. and 500 DEG C., the pressure between 2 and 40 atmospheres absolute, and the contact time between 1 and 15 seconds.  Suitable catalysts include active carbon, silica gel, or metal oxides of large surface area, and may be impregnated with metal salts, for example ferric chloride.  The catalyst may be in the form of a fixed or fluidized bed.  The reactants may be introduced into the reaction zone in liquid or gaseous form, preferably with chlorine in slight excess.  The cyanuryl chloride may either be condensed under pressure to give a liquid, which is then solidified, or it may be permitted to form the solid directly by condensation at atmospheric pressure, or the two methods may be employed successively.  Remaining traces of cyanuryl chloride may be removed from the gases by means of a solvent, for example acetone or toluene.  The by-product hydrogen chloride may be purified by passing it through an absorbent, for example silica gel or active carbon, which may subsequently be employed as catalyst.

Abstract: 397,611. Keyboard switches ; stencil switches. HAGGER, G. C., 20, Avonmore Road, Kensington, London. May 3, 1932, No. 12727. [Class 38 (v).] A control board, for a monogrammic or like sign, of the kind in which plunger switches, each controlling a lamp or group of lamps, are disposed on the board in the same relation as the associated lamps occupy on the sign, and in which the switches when closed are held closed and then all reopened simultaneously, is characterized in that the plunger of each switch carries a contact which dips into a mercury tube below the plunger when the latter is depressed, the mercury forming a fixed contact of the switch. Each plunger may have two such contacts dipping into two separate mercury tubes. The control board is similar in shape to the display board (not shown), and each plunger switch B controls, and corresponds in position to, the associated lamp, or group of lamps, on the display board. This control board is built up of units A, each carrying two rows of switches B and each comprising upper and lower insulating bars A<1>, A<2> connected at the ends by plates A<3>. When a plunger B is depressed, by hand or by passing a small roller over the board in the desired outline so as to depress the appropriate plungers, it moves down until arrested by a bar D, D<1> and its copper strip F bridges two mercury cups G, G<1> in the circuit of the associated lamp. Two glass rods H, H<1> in each unit A coact with a waisted portion F<3> of strip F to hold the switch down. Subsequently, all depressed plungers B in a unit may be raised by raising bar D<1>. The bars D<1> of all units A are raised bv two common eccentric shafts E on axes El one at each end of bars D<1>. Hand wheels E<3> on axes El connected by cranks E<4> are provided so that the turning of any wheel E<3> rotates both shafts E and raises every plunger B on the board which has been depressed. The lower bars A<2> of the units A rest on plywood partitions C<4> so that each division houses the electric leads to the corresponding unit A. Each unit may be removed independently since the bearings E<2> of one of the shafts E are arranged so that the shaft may be readily removed or swung out of the way. The common lead L and the individual lead L<1> to each lamp, pass through holes in the ebonite cups G, G<1> and are bent down into the mercury. For glass cups each lead may be sealed into the bottom or side of the cup or bent over the top edge. To get the necessary outline or picture, a sheet of transparent paper bearing the design is placed over the control board and the roller is passed over the lines of the design to depress the plungers underneath. It is stated that a display board of over 3,000 lamps may be controlled by a control board about four feet by six feet.
