Title: Colouring linear polyesters
Inventor: BOWMAN FRANCIS
IPC: C09B5/36
Filed: 1965-05-20
Abstract: Linear polyesters are coloured by effecting the polymerization of the polyester-forming compounds in the presence of a dyestuff of formula <FORM:1045565/C3/1> where D is a polycyclic dyestuff radical which consists of or includes a group of at least three condensed rings; Y is -NH- or -S-; R represents a substituted or unsubstituted alkyl radical or a cyclohexyl radical; n is 1 to 3; m is 1 to 4; and the benzene ring may be further substituted by chlorine or bromine atoms. The preferred polyesters are those obtained by reacting terephthalic acid or an ester thereof with a glycol of formula HO-(CH2)x-OH (where x = 2-10) or with 1:4-di(hydroxy-methyl)cyclohexane. In the dyestuff D may be an anthraquinone, 11:91-anthrapyridone, 11:91 - anthrapyrimidine, isothiazoloanthrone, pyrazoleanthrone, 31:41-phthaloylacridone or phthaloyl perinone radical. The dyestuff radical may be substituted, e.g. by chlorine, bromine, carboxylic acid, lower alkyl, lower alkoxy, hydroxy, amino, N-lower alkylamino or acylamino groups.  Most preferred dyestuffs are those of formula <FORM:1045565/C3/2> where T1, T2, and T3 are hydrogen atoms or groups of formula <FORM:1045565/C3/3> where R1 is a lower alkyl radical.  In examples, the dyestuff previously wetted with ethylene glycol is incorporated into a monomer obtained by reacting dimethyl terephthalate with ethylene glycol or the dyestuff is incorporated initially with the dimethyl teraphthalate and the ethylene glycol.

Title: Repeater amplifiers
IPC: H04B3/12
Filed: 1973-05-07
Abstract: 1435563 Pilot-controlled repeaters SIEMENS AG 7 May 1973 [19 May 1972 18 April 1973] 21579/73 Heading H4R In a repeater 2 whose frequency response is controlled by an indirectly heated thermistor 81 in response to detected pilot level, the thermistor is connected across the collector and emitter of a limiting transistor 71 whose base is connected to a potential divider 72, 73, 74 also connected across the transistor. Resistor 74 is adjustable and the heater current is produced by differential amplifier 6 which compares a reference 5 with the rectified pilot 4. The temperature dependence of the divider resistors and of the transistor c-e junction may be used to compensate for ambient temperature variation. Alternatively, a further circuit (Fig. 4, not shown) between the amplifier 6 and circuit 7 may generate a further heater current (I z ) in low ambient temperature/low amplifier 6 output conditions to maintain the upper limit of loop amplification. The output of the amplifier 6 is measured in that circuit by a transistor (93) biased by another thermistor (92) located near the first to prevent excessive feedback when the amplifier is not at operating temperature by producing an initial additional heating current (I z ). The normal additional heating current is produced by a transistor (97) turned on by the first (93) and is prevented from leaking through the internal resistance of amplifier 6 by a transistor (95) in series in the amplifierthermistor path.

Title: Improvement in steam or hot water boilers provided with a furnace
IPC: F24H9/18
Filed: 1945-08-25
Abstract: 597,965. Boiler furnaces. SWENDSEN, D. L. Aug. 25, 1945, No, 21863. [Class 51 (i)] The furnace for a steam or hot water boiler is subdivided by a grate into a lower combustion room, into which combustion air is introduced under pressure below the grate by means of a fan, the said combustion room being connected with the heating surface room proper of the boiler, and into an upper fuel magazine for downdraught combustion of wood and other fuel; a branch pipe proceeding from the pressure side of the fan and entering the upper part of the fuel magazine, whereby said part will be set under pressure and uhburnt gases are prevented from collecting in the fuel magazine while the combustion air will become preheated when flowing downwards. The furnace comprises an upper combustion chamber or fuel magazine 2, with a refilling shutter 4, separated from a lower combustion chamber 3 by a hollow grate 1, the walls of both combustion chambers being provided with a water jacket 5 communicating with the water chamber of a heating surface room 6. Water circulates from the chamber 6, up through a lower grate 13 in the lower chamber 3, up the fore-wall of the furnace and through the grate 1. A fan 7 mounted in the fore-wall supplies pressure air for combustion through pipes 8, 9 and out through slit-shaped inlets 11, 12, whose area is adjustable by flexible bars 29 bolted to external plates 32, into the middle and upper parts respectively of the upper chamber 2. The fan also supplies air through a pipe 10, up through the grate 13 to mix with downcoming combustion gases from the chamber 2. The air supply through each pipe is controlled by weighted dampers 14, 19, 24 respectively which move between stops in such a way that when the fan is stopped the position of the dampers is automatically altered. The dampers are adjusted in different positions according as whether the combustion is to take place in the chamber 2 or the chamber 3.
Patent GB-441868-A (GB)
Title: Improvements in the treatment of artificial silk
IPC: D06M11/20
Filed: 1934-07-26
Abstract: Artificial silk having an insoluble tin compound fixed therein is produced by subjecting artificial silk impregnated with a water soluble tin compound to the action of a gaseous reagent yielding a water-insoluble compound with the salt of tin.  Suitable water-soluble tin compounds are stannic chloride, stannic thiocyanate, or stannic chloro-thiocyanate.  Suitable gaseous reagents are steam and/or gaseous ammonia or other volatile base such as methylamine or ethylamine.  An alkaline tin compound, e.g. an alkali metal stannate may be used with carbon dioxide, hydrochloric acid gas or acetic acid vapour as the fixing agent. The reagents may be applied by bath methods, padding, spraying or printing, excess material being removed after a bath treatment, e.g. by hydro extraction with or without drying.  Wetting agents or swelling agents for the material may be included in the solution or the materials may be pretreated with them.  Examples of suitable swelling agents are given.  The tin compound may itself have swelling properties, e.g. stannic thiocyanate or chlorothiocyanate.  The fixing atmosphere may be produced by evaporating an aqueous solution of a volatile base, or the base itself may be injected into a steam chamber.  Fixation is preferably carried out at high temperatures, e.g. 95--105 DEG  C., if desired under pressure.  The process may be continuous the materials passing straight from an impregnating bath or padding mangle with or without hydro-extraction and drying to the fixing chamber.  The fixing time is short, e.g. of the order of 2--5 minutes.  After fixation the material may be washed in water, e.g. at 60 DEG  C., then in cold water and finally scoured in hot dilute soap solution. After fixation the materials may be treated with a water-soluble phosphate or silicate, e.g. cellulose ester materials may be treated with a solution of sodium silicate or tri-sodium phosphate to partially saponify the ester.  In an example cellulose acetate woven fabric is padded with a cold aqueous 20--25 per cent solution of stannic chloride crystals and about 10 per cent of acetic acid.  The material is partially dried at about 50 DEG  C. and then passes in about 4 minutes through a steam chamber at about 100 DEG  C., aqueous ammonia solution being injected into the steam chamber at such a rate that the issuing fabric is substantially neutral.  The weighted material is rinsed in water and scoured with aqueous soap solution.

Title: Switch operating mechanisms
IPC: H01H43/10
Filed: 1971-04-19
Abstract: 1310191 Time switches HOLZER PATENT AG 19 April 1971 [16 Feb 1970] 21900/71 Heading H1N A programme control switch operating mechanism comprises a rotatable main programme cam 47, a rotatable subsidiary programme control cam 1, means 46 for driving the subsidiary cam and mechanical drive means arranged between the cams to drive the main cam step by step on rotation of the subsidiary cam, and means for inhibiting said mechanical drive for a predetermined extent of rotation of the subsidiary cam when the main cam has reached one of a number of predetermined positions. As shown, in a programmer for a domestic washing machine, a motor 46 drives a washdrum reversing cam 1 by its peripheral teeth 3 and a cam surface 4 lifts a lever 22 about pivot 29 thereby stressing a spring 20. When the nose of lever 22 drops off cam 4 spring 20 normally restores lever 22, and a pawl 23 pivoted thereon (at 39, Fig. 3, not shown) steps a main programme cam 47 by means of teeth 19. Cam 47 has recesses or projections on its lower face to operate switches (not shown). A bell-crank lever 15 having arms 30 and 36 is urged by a spring 38 such that a nose 17 on arm 36 follows a track 18 on cam 47 and when it enters a depression (as shown) another nose 16 engages a recess 26 in the lever 22, thereby preventing its release and arresting the stepping of cam 47 by pawl 23. A time-interval counter star-wheel 40, carried on a lever 13 pivoted at 29, is urged by a spring 27 to press against surface 51 on cam 1 and is turned by one tooth each time a counter tooth 11 passes. Teeth 11 correspond in number to the cam surfaces 4 and hence after a predetermined number of normal stepping time intervals an extra long tooth 35 on wheel 40 is brought against surface 51. The subsequent encounter with a tooth 11 pivots lever 13 such that a nose 34 on extension 33 pushes arm 30 to pivot lever 15 and remove nose 16 from recess 26. Lever 22 is thus released and causes pawl 23 to again step cam 47. When lever 22 is released a dog 31 thereon engages lever 13 (as indicated by broken lines in Fig. 3, not shown) and moves wheel 40 clear of surface 51 so that a torsion spring 32 can return wheel 40 to a datum position wherein tooth 35 abuts a lug 14. Different step intervals may be obtained by using a cam 1 with a different number of teeth 11 (and surfaces 4) and/or changing the counter wheel 40 for one with a different number of teeth. Prolonged cessation of stepping may be provided by a solenoid 48 whose armature 52 can engage a hole 24 to restrain lever 22 until a desired water level or temperature, for example, is attained.
