Title: Improvements in or relating to the making of mechanical joints between electrical conductors
IPC: H01R4/62
Filed: 1951-06-12
Abstract: Fluorine-containing compounds are obtained by the action of an acid fluorine-containing substance upon an aromatic or heterocyclic amine, or an aliphatic amide or an aliphatic amine having more than 7 carbon atoms per molecule.  Among examples given of aliphatic amines containing 8 or more carbon atoms are 2 - ethylhexylamine, 3 - di - n - amylaminopropylamine, and trihexylamine.  Examples of aromatic amines are: aniline, ethylphenylethanolamine, phenyldiethanolamine, o-dimethylaminoethyl - p - octyl phenol, and p - (1,1,3,3 - tetramethyl butyl) - phenyl - ethylenedioxy dimethylethylamine. Examples of heterocyclic amines are: 2-oleyl-4-methyl-4-oxymethyl - 2 - oxazoline, azoles, glyoxaline, azines, oxazines, morpholine and indole.  An example of an aliphatic amide is n-hexadecane amide.  The acid fluorine-containing substance may be HF, BF3, HBF4, HB(OH)2F2, H2SiF6, HSO3F or a fluophosphoric acid or a compound which upon decomposition yields the foregoing acidic substances.  Of these HF and HBF4 are preferred.  The suggested amount of fluorine-containing substance used is 0.5 to 60 per cent by weight and it is stated that the substance should preferably be present in the proportion of 11 mol. to each mol. of amine or amide.  When HF is employed 0.5 to 20 per cent of it by weight of the amine or amide is suggested. Compounds according to the invention may be produced by the action of HF on phenylethanolamine or a mixture of substituted oxazoline having a molecular weight of 350 and petrolatum, or a mixture of substituted oxazoline as before, n-octadecane amide and petrolatum, or a mixture of n-dodecylamine and petrolatum, or a mixture of 1-hydroxyethyl-2-heptadecenyl glyoxalidine, petrolatum and mineral spirits or a mixture of substituted 2-heptadecylimidazole and ethylenebis-imino - diacetic acid.  Another compound may be formed by the action of HBF4 on a mixture of aminoethylethanolamine and hydroxydiphenylamine. The compounds are employed for reducing the electrical resistance of joints between conductors.  Specification 719,305 is referred to.

Title: Flat bed knitting machine with patterning mechanism
IPC: D04B15/76
Filed: 1976-04-07
Abstract: 1510913 Knitting machines SILVER SEIKO CO Ltd 7 April 1976 [8 April 1975] 14064/76 Heading D1C A flat-bed knitting machine has a patterning mechanism which makes a preliminary selection of a small group of needles prior to further selection by an element on the carriage so that a single motif can be produced. In operation, rear partitions 204 of the carriage cam mechanism pass closely in front of the butts 102 of needles 103 in rest position and with cam 205 define a butt passage g while the latter with cam 206 defines passage c. Thus butts of needles in first, second and most advanced position travel in passages g, f and c. A pivoted cam 208 is normally biassed against partition 204 but is manually pivotable to and held in a second position in which the needle butts in the second advanced position will be guided into the butt passage g instead of f. Needles whose butts are guided into passage f are further separated by two elements 209 to take passage e or d. For each element 209, there is provided a selection drum controlled by a needle selection control mechanism 106 comprising a perforated control card 600. Needle selection control members 400, 400' moulded e.g. of polyacetal are mirror images of one another and each carry cams 401, 402 and legs 403 whose spacing corresponds to tricks 104 so that these can be mounted at the rear ends of the tricks. Guide members 210 symmetrically mounted on the carriage each comprise integrally moulded thermoplastic cams 212 and 213 forming passage a which continues between cam 212 and a first displaceable cam 215 which with wall 214 forms passage b. A slot 221 in one end of bell crank 219 is connected by pin 220 and linkage 217 to the free end of cam 215, the other end of bell crank 219 being connected to a manually operated rod 223.

Title: Improvements in velocity modulation tubes of the kind comprising a drift space
IPC: H01J25/12
Filed: 1951-06-18
Abstract: 708,276. Velocity-modulated tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 18, 1951 [June 21, 1950], No. 14373/51. Class 39(1) A velocity modulation tube comprising a drift space constituted by a conductive tube 3 of substantially circular cross-section, buncher and catcher gaps 6 and 7 respectively being formed between this tube and conductive tubes 4 and 5 and communicating with buncher and catcher resonant cavities 12 and 13, is characterized in that the drift space is provided with spaced radial or approximately radial extensions 15 which increase gradually in radial depth from about half way along the drift space, with the object of minimizing the loss which occurs owing to the diverging effect of the buncher gap on the electron beam flowing from the cathode 1 and concentration electrode 2 to the collecting electrode 14, which results in electrons impinging on the wall of the drift tube before reaching the catcher gap. Similar extensions 16 may be provided in the wall of tube 5 to reduce secondary emission from the end of this tube, and secondary emission is also reduced by bevelling the ends of tubes 3 and 5 at 17 and 18. The width of the extensions is at the most equal to the width of the catcher gap and the extensions occupy preferably not more than 75 per cent of the periphery of the drift tube. The extensions may be formed by conically milling the drift tube and then providing radial plates, or the extensions themselves may be milled out of the thickness of the tube wall. In a modified construction, for use if the wall of the drift tube is thin, the plates are soldered to the edges of longitudinal slots in the drift tube or alternatively one end of the drift tube may be formed by a peripheral series of members of U- shaped section arranged with their radial depth increasing gradually from about half way along the drift space. The U-shaped members may be interconnected at their outer edges by strips so that the drift tube has a toothed cross-section and electrons are prevented from entering the catcher resonant cavity. Alternatively, a drift tube of the latter form may be pressed out of a piece of sheet material.

Title: Information storage apparatus
IPC: G11C14/00
Filed: 1974-04-02
Abstract: 1461683 Semi-conductor devices WESTERN ELECTRIC CO Inc 2 April 1974 [5 April 1973] 14455/74 Heading H1K [Also in Division H3] A storage matrix uses two terminal metalinsulator-semi-conductor (MIS) capacitors C11 ... C23 ... C31 ..., Fig. 1, each having a capacitance versus voltage characteristic as shown in Fig. 2, the stored data being represented by the stable high or low capacitance values in the hysteresis portion of the characteristic. Readout is effected on a word basis by applying a bias pulse V 0  from a voltage source 11 to a selected row line, the bias pulse being augmented by a short pulse DV when the transient disturbance due to V 0  has passed. Since there are two possible values of capacitance, the data stored is identified by column output detectors A1 to A4 as high or low changes of charge when the short pulse DV is applied. To write or erase data a voltage V of appropriate polarity and corresponding in value to one half of the capacitor switching threshold is applied to each of selected rows and columns. The capacitors are formed on a common P-type silicon substrate 31, Fig. 3, each capacitor being positioned between row and column lines respectively formed by a diffused or implanted N + stripe 32 and a gold stripe 43. Formation of the capacitor structure comprises the growth of an N-type epitaxial layer 33, and the implanting of capacitor isolation rods 34 which can be either P + diffused regions or etched troughs filled with silicon dioxide. The semi-conductor portion is overlaid by two insulating layers 41, 42 between which electric charge carriers induced to tunnel from the semi-conductor are stored, the layers being formed, respectively, of silicon dioxide and aluminium oxide.
