Title: Improvements in or relating to soldering interconnection wires to a conductive pattern carried on a substrate
Inventor: FIELD RONALD LESLIE
IPC: H01L21/60
Filed: 1966-02-17
Abstract: 1,145,155. Soldering. ASSOCIATED SEMICONDUCTOR MFRS. Ltd. 6 Oct., 1966 [17 Feb., 1966], No. 6992/66. Heading B3R. In soldering wires 4 to a conductive pattern carried on a substrate 6 the wires are located above pads 5 of conductive material on the substrate and a continuous strip of solder 3 is provided between the wires and the pads, a jet of heated gas and the solder strip are moved relatively to one another to melt the solder strip which when melted moves across the surface of the substrate and remains at the contact points between the wires and pads. The tinned copper wires are urged by a jig, which also holds the glass substrate, into contact with the flattened flux cored eutectic solder 3 above gold pads 5 and air heated to 330 C. is blown from the nozzle 2 of a pipe 1 on to the strip. The hot air melts the solder to form beads 7 which move in turn across the substrate as the nozzle moves over the strip. Wires may be connected to printed wiring on an insulating board or to an integrated circuit on a semiconductor substrate which latter may be refrigerated to prevent damage by over heating. The substrate may be pre-heated. The gas may be hydrogen, nitrogen or a mixture of gases not containing oxygen. If the gold pads are not evenly spaced dummy wires may be positioned along the strip to gather excess solder and the nozzle may be held stationary while the substrate is moved.

Title: Hollow metal articles and method of making the same
IPC: B21D53/90
Filed: 1929-03-04
Abstract: 328,375. Murray, T. E. March 4, 1929. Hollow-ware; shafts; steam generators. - Hollow metal articles such as boiler headers and axle casings are made by electrically butt welding a series of short pieces in succession to one continuous piece of the desired shape so as to effect the welding by plants of small capacity. One section 10 of a boiler header is formed of channel-section provided with openings 18, 20 in the flanges of such a shape, Fig. 1, that when the section is bent into sinuous form the openings are circular, as shown in Fig. 2. Similar short sections with openings staggered relatively thereto are then prepared and the short sections electrically butt-welded successively at 22 to the continuous section. The ends of the short sections are formed with walls arc welded or brazed together. The meeting edges 32, 32<a> of the parts may cut across the openings in lines substantially parallel to the length of the header as shown in Fig. 4 so as to facilitate welding. In forming an axle casing sections 41 - - 44 are separately welded to the section 40, the abutting edges of the short sections being also welded together. The sections 41, 42 may be replaced by a single central section. The joints between the short sections may be inclined instead of perpendicular to the axis of the casing so as to afford greater resistance to torsion.

Title: Improvements in or relating to arrangements for stereophonic reproduction of signals
IPC: H04S1/00
Filed: 1961-02-27
Abstract: 949,225. Stereophonic reproduction. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 27, 1961 [March 2, 1960], No. 7095/61. Addition to 926,357. Heading H4L. In order to improve the reproduction quality in the apparatus for the reproduction of stereophonic signals A and B described in the parent Specification, in which the transmitted signal is in the form of a carrier frequency modulated by the sum signals A+B, and frequency modulated by a subcarrier, e.g. 35 kc./s., amplitude modulated by the difference signals A-B, there is connected between the frequency discriminator 13 and the amplitude detectors 31, 32, a frequency-dependent attenuator 45, 46, 47 having a higher attenuation for the frequency band of the audio frequency sum signal than for the frequency band of the difference signal modulated on the sub-carrier, the attenuation being substantially uniform over both bands. By this means non-linear distortion introduced by the detector 31, 32 is reduced, but a frequencydependent cross-talk is introduced. This is removed by shunting the resistor 41 with a series connection of the resistor 48 and capacitor 49. The time constant of this circuit together with the cathode resistors 23, 24 and 25, 26 is arranged to be equal to that of the circuit 45, 46, 47. In practice the resistor 48 may be omitted. The arrangement emphasizes the higher audio frequencies and this is corrected by connecting in series with each of the anode resistors 27, 28 of the amplifiers 17, 18, a capacitor 50, 51 shunted by a resistor 52, 53 respectively, the time constants of networks 50, 52 and 51, 53 being equal to that of the attenuator 45, 46, 47. These measures may be incorporated in a transistorized receiver. In an alternative arrangement, Fig. 3 (not shown), an inductor is connected in series with the resistor 46 and the capacitor 47 dispensed with. A common output impedance, consisting of a resistor and capacitor connected in parallel, is included in the output circuit of the amplifiers 17, 18 to reduce the frequency-dependent crosstalk and produce a smooth frequency characteristic. The modified attenuator may be used in place of the attenuator in the circuit of Fig. 1 and the other correction circuits may be interchanged.

Title: Improvements in liquid depth indicators
IPC: G01F23/16
Filed: 1931-03-07
Abstract: 374,464. Elastic-diaphragm pressure gauges. LEWIS, W. W., 15, Vine Street, Clerkenwell, London. March 7, 1931, No. 7114. [Class 106 (ii).] In a pressure gauge for use with a pneumatic liquid level indicator, one wall of an expansible chamber 1 carries a bar 3 to one end of which a second bar 4 is pivoted at 6. The bar 4 carries a projecting pin 5 engaging one arm of a bell-crank lever 7, the other arm of which is connected by a link 10 to a cranked spindle 11 carrying a pointer 15. The point of engagement of the pin 5 with the lever 7, and therefore the multiplication of movement transmitted to the pointer, may be adjusted by swinging the bar 4 about its pivot 6 and securing it by a screw 20 passing through a slot 19. The position of the pin 5 may also be adjusted by means of the screw 20 which is threaded through the bar 4 so that the latter with its pin 5 may be moved towards or away from the chamber 1. The Provisional Specification refers to a fine wire attached to the longarm of the bell-crank lever to bring the pointer to zero.

Title: Improvements in and relating to writing implements
IPC: B43K21/00
Filed: 1933-03-10
Abstract: 407,824. Pencil holders; leads. WAHL CO., 1800, Roscoe Street, Chicago, U.S.A. March 10, 1933, No. 7301. Convention date, Aug. 24, 1932. [Class 146 (iii).] A propelling pencil comprises a lead-holding tip to which a lead of polyhedral crosssection is guided by a guide tube which is enlarged in its middle part to permit the lead to adjust itself to enter the tip, and constricted at its rear end to a bore which prevents rotation of the lead passing therethrough. The pencil comprises a guide tube 22, Fig. 1, fixed to a tip body 21 and rotatable in a barrel 20. The top of the guide tube is swaged down to an almost square crosssection, and split at 24c, so that, as shown in Fig. 5, it firmly grips a polyhedral lead 10, and prevents it from rotating. The empty spaces left at the corner between tip and lead permit the use of an oversize lead and allow the escape of dust shaved from the lead. The flat sides 25 of the tip bore disappear gradually into the circular portion of the tube, thus forming guide surfaces for the lead entering the tip. A screwthreaded plunger 27 is provided with a sphere 28 riding in grooves 29 in the barrel, and is adapted to be led forward by co-operation with screw threads 26<a> on a swaged-in portion 26 of the guide tube. The portion 26 also acts as a form and size gauge for leads, which are introduced from the rear after withdrawal of the plunger. In a modified construction the guide surfaces extending upwards from the tip may be of a spiral form.

Title: New diamines and salts thereof
Inventor: ROBINSON FRANK ARNOLD
Filed: 1955-03-14
Abstract: The invention comprises compounds of the formula: <FORM:0786215/IV (b)/1> and salts thereof (other than penicillin salts), where a, b and c may be the same or different and are 1, 2 or 3, and R is hydrogen, an alkoxy, hydroxy or halogeno group, or an alkyl group of not more than three carbon atoms.  The compounds are made by reducing a Schiff's base of the formula: <FORM:0786215/IV (b)/2> where w is 0, 1 or 2 and x and y are 1, 2 or 3, or the formula: <FORM:0786215/IV (b)/3> where w1 is 1, 2 or 3 and x1 and y1 are 0, 1 or 2, R having the meaning given above.  The Schiff's base is made by reacting an aldehyde of the formula: <FORM:0786215/IV (b)/4> with a diamine of the formula: <FORM:0786215/IV (b)/5> or by reacting an amine of the formula: <FORM:0786215/IV (b)/6> with a di-aldehyde of the formula: <FORM:0786215/IV (b)/7> where w, x, y, w1, x1, y1 and R have the meanings given above.  The reduction is effected with hydrogen in the presence of a platinum, palladium or Raney nickel catalyst. Organic solvents such as aliphatic alcohol, benzene, pyridine or acetic acid or mixtures of solvents may be used.  The reduction may also be effected by sodium and a lower aliphatic alcohol.  The condensation is effected by heating a mixture of the two reactants or by refluxing the mixture in the presence of an organic solvent such as an anhydrous lower aliphatic alcohol or benzene.  The dihydrochloride and diacetate salts are made by treating the diamine in alcohol with anhydrous or alcoholic hydrogen chloride or with glacial acetic acid. In examples, diamines are made by reducing the product obtained by condensing (1) benzylamine, (3) b -phenethylamine, (6) p-methylbenzylamine, (9) g  - phenyl - n - propylamine, and (21) p-chloro-benzylamine with terephthaldehyde; (12) benzaldehyde, (15) ptolualdehyde, and (17) anisoaldehyde with a  : b 1 - diamino - 4 - ethyl - toluene ; benzaldehyde with (19) b  : b 1 - diamino - 1 : 4 - diethylbenzene and (20) b  : q 1 - diamino - 4 - ethyln - propyl - benzene; and p - hydroxybenzaldehyde with (22) p-xylylenediamine.
