Patent GB-1375046-A (GB)
IPC: B23K9/28
Filed: 1971-05-11
Abstract: 1375046 Welding by fusion R NEVILLE 11 May 1972 [11 May 1971 (2)] 14316/71 and 14317/71 Heading B3R  A transferred arc non-consumable or consumable electrode arc welding tool comprises an electrode holder 15 fast with the downwardly spring-pressed plunger 14 of a solenoid having a coil 11 disposed in the arc current circuit through the electrode and the workpiece, this arrangement providing for axial vibration of the electrode (e.g. for easy arc striking), contact of the workpiece by the electrode causing solenoid energization and an electrode withdrawal, said withdrawal in turn causing the arc current circuit to be broken and allowing the electrode to be spring returned into contact with the workpiece to renew the cycle. The electrode/ workpiece return speed may be adjusted by adjustment of spring loading and/or electrode holder displacement. Trigger-controlled, shortcircuiting means cuts out the solenoid for non- vibratory use. When using a non-consumable electrode, the tool may be used for heating a workpiece such as to melt soldering or brazing compounds.  In Fig. 1, the ends of the coil 11 are respectively connected to a supply cable C and, through a leaf spring 20 and the plunger 14, the electrode. A casing and handle 10 are of insulating material. A downwardly acting spring 24 is pressure adjusted and plunger displacement is determined by screw knobs 21, 23 respectively. A trigger 25 in the released position shown, allows a spring blade contact 26 to short-circuit a solenoid supply cable end 11a to the plunger 14. On pulling up the trigger, the solenoid is rendered operable. The trigger may be arranged to operate in the reverse manner. In Fig. 2, the downwardly acting spring 24a is shown acting on the electrode holder 15 via a metal disc 32. The ends of the coil 11 are respectively connected to the supply cable C, via a ring 26a and the casing 26, and to the electrode holder. An insulated trigger 28 comprises a pivotable conductive bridge 29 through which is positioned a set screw 31 co-operating with a rotatable, slotted, insulating collar 30. When the latter is rotated so that its slot is not aligned with the screw, the trigger may be upwardly moved and correspondingly an end 29a of the bridge 29 may be downwardly moved to limit, in co-operation with the disc 32, electrode holder displacement, the latter being determined by the setting of the screw. When the collar is rotated to align its slot with the set screw, upward trigger movement may extend to a position in which the bridge end 29a contacts the disc 32 and the set screw 31 contacts a sleeve 27 electrically connected to the cable C to shortcircuit the solenoid. In Fig. 3 (not shown), short-circuiting is effected by raising a trigger to connect the supply cable to the plunger, via a conductive casing or, where the casing is non-conductive, a further conductive means.

Title: Method of adjusting electrical filters
Inventor: GROVER ERIC HOUGHTON
IPC: H01P1/208
Filed: 1969-03-19
Abstract: 1,253,306. Waveguides. STANDARD TELEPHONES & CABLES Ltd. 19 March, 1969, No. 14391/69. Heading H1W. [Also in Division G1] A method of adjusting a multi-cavity filter consists in detuning the sections of the filter and monitoring the frequency characteristic of the energy reflected from the filter as the sections are tuned one at a time starting from the input end. The filter may consist of waveguide cavities coupled by irises, or it may be a comb-line filter forming the output of a frequency multiplier. As a preliminary step, all the sections of the filter are detuned, e.g. by screwing in the tuning screws to their fullest extent, so that all input energy is reflected. A recurrent train of continuous oscillations swept over the intended pass-band is applied to the input and the frequency curve of the reflected signal observed on an oscilloscope. As the first resonator is tuned and becomes transmissive a dip in amplitude is observed and the tuning is adjusted to position this dip at the centre of the frequency characteristic. The procedure is repeated for the second, third &c. cavities, the last cavity being tuned by monitoring the output response of the filter. The frequency characteristic consists of an array of dips which are arranged symmetrically about a central frequency. Further adjustment of the screws is then made to improve the shape of the frequency response curve. The input to the filter may comprise a diode frequency-multiplier fed through an impedance-matching LC network and choke tuned to the output frequency of the multiplier. This prevents feedback of the output. As a preliminary to adjusting the filter, the LC network is adjusted by observing and shaping the frequency response curve of the whole arrangement.
Patent GB-572906-A (GB)
Title: Improvements in or relating to cellulosic derivatives and to fabrics coated therewith
IPC: C08B15/00
Filed: 1943-09-03
Abstract: A dispersion of an organic derivative of cellulose soluble in organic solvents and insoluble in water is kneaded or milled together with an alkyl ether of dimethylol urea at a temperature below that at which the cellulose derivative is rendered insoluble in organic solvents, and thereafter the mass is cured by heating it to a temperature at which insolubilization of the cellulose derivative occurs.  The kneading or milling is preferably carried out at a temperature below 100 DEG  C. and the curing is carried out above 100 DEG  C.  The proportion of the ether of dimethylol urea is preferably within the limits of one part of urea compound to five parts of cellulose derivative and one part of urea compound to twenty parts of cellulose derivative.  The milled material may be calendered directly on to a fabric base without dispersing it in solvents and the product is then cured on the fabric at a temperature which insolubilizes the cellulose derivative.  The coating so treated is unaffected by ordinary solvents and it has a greatly reduced thermoplasticity.  In an example, ethyl cellulose, hydrogenated methyl abietate, acetylated castor oil, carnauba wax and titanium dioxide are kneaded together and then a solution of dimethyl ether of dimethylol urea is added and mixing is continued.  The mixture is transferred to a calender and applied to a fabric after which the coating is cured at 107 DEG  C. The coating is then insoluble in ethyl alcohol, ethyl acetate, benzol, and many other solvents and is non-thermoplastic.  In another example, the diethyl ether of dimethylol urea, obtained by dissolving dimethylol urea in ethyl alcohol in presence of hydrochloric acid and subsequently neutralizing with caustic soda, is used instead of the dimethyl ether of dimethylol urea.  In another example, benzyl cellulose is mixed with butyl phthalyl butyl glycollate and ethyl acetate so that it is swollen but not dissolved.  The swollen mass is then milled until the ethyl acetate has been evaporated.  An alcoholic solution of dimethylol urea diethyl ether is added and milling is continued until the alcohol has evaporated.  The mass is calendered on to a fabric and then cured by heating.  In another example, cellulose acetate is kneaded with dimethyl phthalate, methyl phthalyl ethyl glycollate and acetone.  An alcoholic solution of dimethylol urea diethyl ether is added and mixing is continued till the alcohol has evaporated.  In another example, cellulose acetopropionate is mixed with butyl phthalyl butyl glycollate, and ethyl acetate, and then a solution of dimethylol urea in butyl alcohol is added. Milling is continued until the excess of butyl alcohol has evaporated.  The mass is then calendered on a fabric and cured at 127 DEG  C.  To facilitate the heat curing, a small amount of phthalic anhydride may be present as a catalyst.
