Abstract: 791,163. Locking screws. MORGAN, H. R. Jan. 12, 1955 [Jan. 19, 1954], No. 1590/54. Class 89(1) A screw 1, Fig. 1, having a head 2 seated in a recess 3, is locked by a bar 4 engaging castellations 5 and flattened, eg. by a hammer-blow, to cause its pointed ends to engage the recess-wall. In another arrangement for a socket-head screw 8, Fig. 5, the bar 10 has an integral projection 11 to engage the socket. In a modification, the projection 21, Fig. 16, is bent out of the strip from which the bar 22 is made, and in a further modification, the projection is pressed from the strip. According to a further arrangement, the bar 30, Fig. 22, has its ends bent to trail in the screwing- home direction. After tightening, the ends are bent in the opposite direction by a tool 32 to engage the recess wall. For locking a screw-head having longitudinal ribs and grooves 14, 15, Fig. 11, on its periphery, the bar 16 has downwardly and inwardly-bent projections 17 which engage opposed grooves 15 and slide therealong when the bar is deformed, to dig its serrated ends 19 in the wall of the recess. Removal of the bar in all cases except Fig. 22, is effected by prising. In Fig. 22 the ends are reversely bent by the tool.

Title: Arrangement for the continuous supervision of the adjustment of the contacts in moving contact electric converters
IPC: H02M1/26
Filed: 1950-01-20
Abstract: 675,235. Rectifying. AKT.-GES. BROWN, BOVERI, & CIE. Jan. 20, 1950 [Jan. 20, 1949], No. 1602/50. Class 38 (ii). So that the setting of the contacts of an oscillating contact converter can be continuously supervised, means are provided whereby the voltages at the individual contacts at the instant of switching-in are measured and compared. Fig. 1 shows that where a change in contact duration from α 1  to α 2  has resulted from alteration in the setting of a contact, the switching-in voltage, just after the voltage passes through zero potential, changes from 81 to 8<SP>2</SP>. In Fig. 2, A.C. input 3 supplies a D.C. circuit 4 through a rectifier comprising moving bridging contacts 11-16 and switching reactors 2a-2f. D.C. voltmeters 5-10 connected across the switches with appropriately directed blocking rectifiers 17-22 in series indicate the value of the +ve blocking voltage across the contacts up to their connection by the moving bridges. The voltmeter readings are thus a measure of contact duration, and if any contact moves from its setting it may be re-adjusted, e.g. by varying the length of the push-rod actuating the contact bridge. Fig. 3 shows an arrangement in which the switching- in voltage at each contact is compared with the mean value of the voltage at all the contacts. This latter mean value is developed across resistances 26a, 26b from the output rectified at 25a, 25b of two secondary windings of transformer 24, the two primary windings of which, being connected in series with blocking rectifiers 23a, 23b across the switches 11, 13, 15 and 12, 14, 16 respectively, carry currents dependent on the sum of the switching-in voltages. The individual switching-in voltages are developed across resistances 27-32 and compared with the voltages across resistances 26a, 26b in voltmeters 27-32. Modifications are described in which the individual switching-in voltages are compared with the voltage at an auxiliary contact operated synchronously with a main contact, Figs. 4, 5 (not shown). Specification 663,022 is referred to.

Inventor: HEINE JOHN
IPC: B23K1/14
Filed: 1918-01-28
Abstract: 123,553. Heine, J. Jan. 28, 1918. Soldering.-In a can-seamsoldering machine, the bar which feeds the solder to the joint is fed by capillary action. The can bodies are moved by chain mechanism past a flux-applying device, in rubbing or rolling contact along a bar partly immersed in molten solder, past a wiping wheel or other device and an air-cooling blast. In the machine for soldering vertical seams shown, the can bodies are carried in guide-bars 11, 12, 13, 14 supported by brackets 15, Fig. 4, adjusted vertically in slotted members carried by slides 17, 18 adjusted horizontally by right and left handed screws 16, Fig. 1. The support of the sprocket wheel 23 at the takeoff, or left-hand end is fitted with tension bolts. The solderbath 26 is adjustably supported by brackets and carries lugs 29, Fig. 5, which support the feed bar comprising two parts 30, 31 with cavities 33, slots 34 and capillary grooves 36 arranged alternately on the parts 30, 31. The normal level is shown at 39. When the bath is heated, capillary action maintains a film on the face 38. Alternatively, the capillary passage may be a very narow slot formed by bolting the bars together with slips or wires inserted between at intervals. The bath is heated by a gas burner tube 40, Fig. 3a, supplied with pressure air from a nozzle. A shroud 46 encloses the flame. A coolblast pipe 49, Fig. 2, plays air on the sweated seam to set the solder. An adjustable fluxing- bath 50, Fig. 3a, with a belt-driven wheel 52 and a wiper 55 contains hydrochloric acid, zinc chloride, or other flux. An angularly arranged cl wiper wheel 60, Fig. 2, driven through belt gearing from a longitudinal shaft 66 driven by toothed gearing from the shaft 56 is mounted rearwardly of the solder-bath 26. The shaft 66 is connected up to drive the chain 25 which carries claws to push the can bodies 54 along the rase 11 - - 14 in rubbing contact with the face 38. The machine is modified to adapt it for circular rim seams. The can bodies in this' case are caused to roll in contact with the soldering bar, and the fluxing and wiping operations may be done by endless bands.

Title: Process for the manufacture of secondary amines
IPC: C07D405/04
Filed: 1963-01-14
Abstract: <PICT:1028401/C2/1> Secondary amines are prepared by reacting an N-substituted imino-ether (including cyclic compounds of structure at about room temperature with a reactive esterified alcohol, and hydrolysing the product. Suitable reactive esters are those of hydrohalic, sulphuric or organic sulphonic acids.  The secondary amine product contains (1) the radical on the N atom of the imino-ether, and (2) the radical of the alcohol.  Solvents may be used.  The imino-ethers may be derived from any carboxylic acid, especially amino-acids or peptides, and may be used as such or as salts. Examples prepare N-methyl-cyclohexylamine (and its 3,5-dinitrobenzoate), N-methyl tryptophan methyl ester hydrochloride, N-methyl-L-tyrosine methyl ester (and hydrochloride) and N-methyl-L-phenylalanine ethyl ester (and picrate).  Starting materials in examples.  The compound [Ag(C6H6)2]BF4 with g -chloro-N-cyclohexyl butyramide in CH2Cl2 gives 2-cyclohexylimino-tetrahydrofuran, which with CH3I gave its methiodide.  L - Tryptophan methyl ester (from hydrochloride and triethylamine) with Cl(CH2)3- COCl and pyridine in CH2Cl2 gave g -chlorobutyrul - L - tryptophan methyl ester, which with AgBF4 gave N-tetrahydrofuranylidene-(2)-L-tryptophan methyl ester.  N - tetrahydrofuranylidene-(2)-L-tyrosine methyl ester and N-tetrahydrofuranylidene - (2) - L - phenylalanine ethyl ester were obtained analogously, with the analogous intermediates.

Title: Improvements in arrangements for matching a load to the internal resistance of a generator

Filed: 1946-01-18
Abstract: 606,759. Impedance-matching. PHILIPS LAMPS, Ltd. Jan. 18, 1946, No. 1752. Convention date, March 18, 1941. [Class 40 (viii)] For matching a load Ru, such as an aerial, to a resistance Ri, such as that of a shortwave generator, throughout a band of frequencies, several sections of transmission line, connected in tandem, have characteristic impedances Z1, Z2, Z3, suitably calculated, and have each a length l which is a quarter of a wave-length at the mid-band frequency. When three sections are used, the impedance W3 at the input end is given by the equation where p is the phase change per unit length at a frequency within the band, and the as and bs are calculable functions of Z1, Z2, Z3, and Ru. According to the invention the values of Z1, Z2, Z3 are so chosen that a0/b0=a1/b1=a2/b2= Ri/Z3. The remaining ratio a3/b3 is then equal to Ru/Z3' but the resulting mismatch is small since cot pl is small when l approximates to a quarter of a wave-length. The method can be extended to any number of sections.

Title: Improvements in or relating to apparatus for detecting tramp iron in non-metallic materials on belt conveyors or similar transport systems
Inventor: SOHNEMANN KURT HEINRICH
IPC: G01V3/10
Filed: 1952-01-22
Abstract: 697,895. Locating conductive and magnetic bodies. ETABLISSEMENTS E. CLEMESSY. Jan. 22, 1952, No. 1791/52. Class 37. Electrical apparatus for detecting tramp iron on a belt conveyer or similar transport system includes an electrical or mechanical device, the time constant of which corresponds to the time the tramp iron takes to pass through the search apparatus. An electromagnet connected to A.C. mains is placed above the belt conveyer, below which are arranged search coils S, Fig. 1, adjusted so that the sum of their voltages is zero. When tramp iron passes beneath the coils the balance is upset and a voltage U1 is generated, which is amplified by a valve V and rectified by a valve V2. The rectified current charges a capacitor C1, the D.C. voltage of which is applied, through a capacitor C2 and an amplifier V3, to a signalling system A. Resistors W1, W2 discharge the capacitors C1, C2. The capacitance of the capacitor C1 is of such a value that it is just fully charged during the passage of the tramp iron. The voltage U2 applied to the amplifier V3 is reduced to zero in case of small slow dislocations of surrounding steel masses. In the case of small sudden shocks the charge of the capacitor C1 is insufficient to operate the signalling system. In a modification, Fig. 2, time limit relays are used which make or break contacts after a lapse of time corresponding to the time taken by the tramp iron to pass through the search apparatus. The search coil voltage is rectified by two valves V2, charges capacitors C1, C2, and is amplified by valves V3. The output is applied to a centre-tapped relay R1 which operates its contact K1 when the search coil voltage rises or falls. The first operation energizes a time limit relay R2, which energizes a relay R3 by closing its contact K2. The contact K2 remains closed during the time the relay R1 opens and closes its contact K1 when the first impulse due to the rising voltage of the search coils is finished and the second impulse due to the dropping voltage operates the relay R1. The second impulse energizes a relay R4 over contacts K1, K3, closing its contact K4 and operating the signalling system. If the first impulse is not followed during a certain time by a second one, a new impulse does not operate the signalling system as the relay R3 has been cut out by the contact K2 of the relay R2.
