Patent GB-454968-A (GB)
Title: Treatment of textile materials
IPC: D06M11/46
Filed: 1935-04-12
Abstract: Water-insoluble compounds of metals of the fourth group of the periodic classification, including tin and titanium, are fixed on textiles by impregnating with a double salt of a weak polybasic acid with a volatile nitrogenous base and one of said metals, then decomposing the double salt with formation of the insoluble compound on the material.  Suitable double salts are ammonium titanium tartrate, carbonate, oxalate or citrate, ammonium stannic oxalate, &c.  The ammonia may be replaced by methylamine, p  ethylamine or the like.  The double ammonium salts are readily decomposed by heat in presence of moisture or with the aid of steam and ammonia as described in Specification 441,869.  The solution may be applied locally to obtain patterned lustre effects; the impregnation and decomposition may be carried out continuously.  Wetting agents or swelling agents may be incorporated in the solution, or the material may be pre-treated with such agents; a titanium salt, e.g. the oxalate or tartrate, may be employed in sufficient concentration to cause a swelling action.  In examples: (1) a lustrous cellulose acetate fabric is padded with a solution containing 5 per cent of diethylene glycol and ammonium titanium tartrate in quantity equivalent to 2,5 per cent of titanium dioxide.  The padding mangle is adjusted so that the fabric retains 150 per cent of its weight of the liquor.  The material is steamed for 10 mins in the presence of a little ammonia, washed and dried.  The lustre is considerably reduced; (2) A regenerated cellulose artificial silk fabric is padded with a solution of titanium ammonium carbonate having a titanium content equivalent to 1,5 per cent of titanium dioxide, so that the material retains 150 per cent of its weight of liquor.  The material is then dried and steamed, and its lustre reduced.

Title: Improvements in and relating to slurcock deflecting devices for straight bar knitting machines
IPC: D04B11/00
Filed: 1948-04-27
Abstract: 687,062. Knitting-machines. BATA, NARODNI PODNIK. April 27, 1948. [May 8. 1947] No. 11499/48. Class 74 (ii). The traverse of the slurcock of a straight-bar machine, during the knitting of a narrowed part of an article, is shortened so that the slurcock operates only those sinker jacks necessary for the formation of the narrowed part, and the machine is provided with cam means which withdraws the slurcock from engagement with the sinker jacks at each end of its traverse. The slurcock 1 is slidably mounted in its box 2 under the influence of a spring 4 but is normally retained in its operative position by a pivoted detent 39 engaging a slot 40 in the slide of the slurc o ck. A roller 6 depends from the slide and engages a groove 7 formed in the guide bar 3, the groove being widened at 11, at positions corresponding to the ends of the slurcock traverse during the knitting of the narrowed part, and is provided with a slot 8 which accommodates a movable cam 9. A pivoted lever 46 retained within a recess 48 in the guide bar 3 by a spring 49 is projected by a finger 50 when the cam 9 is raised to project into the groove 6. When a narrowed part of the article is being knitted the cam 9 and finger 50 are raised through a system of levers by the machine, the finger 50 deflecting the lever 46 beyond the edge of the bar 3 so that when the slurcock approaches the cam 9 the detent 39 is disengaged from the slot 40. The roller 6 is then engaged by the cam 9 so that the slurcock is withdrawn from contact with the sinker jacks. On completion of the narrowed part, the cam 9 is withdrawn and the slurcock travels the full width of the needle row. Specification 686,523 is referred to.

Abstract: 464,880. Field control of two motors. ELMQUIST, K. G. T. April 22, 1936, No. 11538. Convention date, May 3, 1935. [Class 38 (iii)] A motor 1 having a field excitation system comprising two aiding portions 12, 13, and a motor 2 having a field excitation system comprising two opposing portions 14, 15, drive a shaft 8 through differential gearing, the field portions 13, 15 being fed from a constant voltage source, and the other field portions 12, 14 being energized in dependence on the anode current of a grid-controlled discharge device 16, the arrangement being such that for one value of anode current the motors run at such speeds that the shaft 8 remains stationary while with an increase of anode current one motor overruns the other to give. rotation of the shaft 8 in one direction, and, with a reduction of anode current, the said one motor under-runs the other to give rotation of the shaft 8 in the opposite direction. The field portions 12, 14, are connected in series and damping resistances 19, 20 may be connected in the circuits of the field portions 13, 15 to prevent disturbing interaction between the field windings. The motors 1, 2, drive respectively sun-wheels 3, 4 of gearing having planet wheels 9, 10 driving the shaft 8. The shaft 8 may operate a voltage regulating device controlling the grid circuit of the device 16 so that rotation of the shaft restores the voltage of the grid. In a modification, Fig. 2 (not shown), each motor has one field winding only, and each field winding has an intermediate tap, the connections between the contant voltage supply, the circuit including the grid-controlled discharge device, and the tapped motor fields being such that two field currents (one constant and one controlled) assist each other in one part of the field winding of one motor, and oppose each other in one part of the field winding of the other motor.

[Class 146 (i).] A device for securing a booklet or other folded sheet in a binder comprises a strip 1 adapted to lie within the folded sheet and having perforated tabs 2 thereon which pass through slits in the folded edge of the sheets so as to be threaded on binding members, a slit or slot being formed along the portion of the strip lying within the sheet for the reception of a further folded sheet. If the strip is made of flexible material such as paper or linen, a slit 5 is formed in the strip for the reception of the additional sheet and the inner margin 4 may be coated with adhesive for securing the strip to the main sheet. A slot 5 is provided instead of the slit when the strip is made of rigid material such as metal, and in this case the tabs 2 may be hinged thereto. Where the printed matter on the main sheet extends to the fold, the strip 1 is made of transparent tracing linen. In one form, the slot is formed by cutting away the material to a greater depth at a, b between the tabs 2 than it is on the ends of the strip, and in this case adhesive may be applied to the ends only of the strip. The slot 5 may be made long enough to take both the main and additional sheets.

Title: Improvements in and relating to electric valve circuits

Filed: 1938-04-22
Abstract: 491,064. Valve circuits. BRITISH THOMSON-HOUSTON CO., Ltd. April 22, 1938, No. 12109. Convention date, April 24, 1937. [Class 40 (v)] In a circuit in which a relay is energized for a predetermined number of cycles of alternating current, a variable condenser which controls the time period is charged both from an impulse source and from current in the anode-cathode path of the valve. The valve 9 is normally biassed to cut-off by tapping 17 connected to control grid 13 and condenser 23 is discharged. When switch 31 connects 23 to 20, peaky impulses are generated by the saturable inductive device 25 and are impressed on grid 12, each impulse being sufficient to overcome the bias on grid 13 and render the valve 9 conducting. Each impulse also puts a charge on condenser 23 and the cumulating charge is augmented by additional charges received over 33 whilst the valve is conducting. After the predetermined number of impulses condenser 23 becomes fully charged and further impulses have no effect on valve 9 which remains non- conducting until switch 31 is operated to allow condenser 23 to discharge over 32. Relay 5 in the valve circuit is energized whilst the valve passes current and connects up an electric welding apparatus 1.
