Title: Improvements in or relating to electric pulse train generating systems
Inventor: FRENCH JAMES ALFRED THOMAS
IPC: H04Q3/42
Filed: 1955-12-29
Abstract: 856,925. Automatic - exchange systems. POSTMASTER GENERAL. Dec. 28, 1956 [Dec. 29, 1955], No. 37319/55. Class 40 (4). An electric pulse train generating system comprises a plurality of transformer cores, each having a primary winding connected to at least one source of cyclically recurring pulses, and a plurality of pulse train output leads each inductively coupled to a different selection of the cores. Fig. 2 shows a method of combining pulses. Horizontal leads LPA, LPC are normally at a potential of +V and receive earth pulses LP1-10, LP11-20, and so on. Vertical leads SP1-SP10 are normally at earth potential and receive single unit pulses P1-P10 of potential V. Rectifier MR1 then conducts only at the coincidence of pulses on leads SP1 and LPA to generate a pulse in lead PL. To avoid faulty operation due to +ve going and - ve going pulses ending at the same time additional overlapping long-pulse trains may be applied to leads LPB, LPD, each horizontal lead being then concerned with the generation of pulses in only five of the ten pulse positions. This arrangement is developed in Fig. 3 where vertical leads SP1-SP5 are connected to rings in the first and third rows, SP6-SP10 to rings in the second and fourth rows. Current flows normally in the horizontal leads and is cut-off at the application of earth potential to the grid of the corresponding tube VA-VD. Each primary winding may be shunted by a rectifier MR5, Fig. 2, which reduces the impedance of the winding in the absence of the predetermined combination of pulses. Translator. In the schematic, Fig. 6, code and translation cycles are synchronized and applied to two coincidence gates. The code digits in the register are also applied to one of the gates which at coincidence opens the other gate so that the corresponding translation is sent to a storage device. Dialled digits are stored in REG1, Fig. 7, in a 2 out of 5 code in a 200-pulse cycle. For every possible code there is a code wire CPW threaded through appropriate rings in a matrix P1-P30 to which pulses P1-P30 are applied in a 100-pulse cycle. The corresponding translation wire TPW is threaded through the corresponding translation rings and also through one or more special instruction rings P40-P50. The common input for wires CPW, TPW receives a long pulse P1-200 at an appropriate time in the code cycle. The code wire feeds pulses generated by the corresponding rings in the range P1-P30 through a pulse reshaper CPR1 to a coincidence detector. The detector comprises two gates SG1, SG2 and a trigger circuit TC. Whenever coincidence is not found between pulses on a code output lead such as C01 and that in the register then TC is reset. When, however, coincidence is found for all the digits in the code then TC remains operated to keep open register coincidence gate RG1 and the information on the translation wire TPW in pulse positions P101-P150 is transferred to an appropriate store. Specification 845,506 is referred to.

Title: Improvements in or relating to the treatment of cellulosic textile fabrics
IPC: D06M13/487
Filed: 1963-09-24
Abstract: Cellulosic fabrics, e.g. woven, non-woven or knitted fabrics composed wholly or partly of cotton, regenerated cellulose or cellulose derivative fibres, are creaseproofed by impregnating them with an aqueous solution containing 5-40% by weight of a salt as a swelling agent for cellulose and a cellulose cross-linking agent and then heating them at a temperature of at least 100 DEG C. Suitable swelling agents are zinc chloride or thiocyanate, lithium bromide and magnesium perchlorate.  The cross linking agent may be an acetal formed from formaldehyde and diethylene glycol, dimethylolmethyl carbamate, dimethylolethylene urea, dimethylol propylene urea, dimethyloldihydroxy ethylene urea, 1, 3, dimethylol-5-hydroxyethylperhydrotriazone-2, tetramethylol melamine, water soluble etherified methylol melamine compounds, the diglycidyl ether of ethylene glycol, glyoxal, formaldehyde, glutaraldehyde, epichlorhydrin, the reaction products of pyridine with chloromethyl ethers, divinyl sulphone derivatives, tris(1-azividinyl)-phosphine oxide and 1, 6-di(ethyleneiminocarbonamide)-n hexane.  The impregnating solution may also contain catalysts, e.g. oxalic or citric acid, magnesium chloride or per fluoborate, zinc fluoborate, ammonium sulphate, zinc nitrate and sodium carbonate.  After impregnation the fabric may be heated at a temperature of 100 DEG -150 DEG C for 1-10 minutes or it may be dried at 50 DEG -100 DEG C before heating at a temperature of at least 100 DEG C.  The fabric may then be washed and dried.  Before, simultaneously with or after impregnation with the aqueous solution the fabric may be treated with a cation-active or ketene-type softener.  The fabric may also be calendered after impregnation either before or after heating. Specification 504,916 is referred to.

Abstract: Substituted rhodanines of the general formula <FORM:0829644/IV (b)/1> wherein R1 is alkoxy, aryl or aryl substituted with halogen, alkyl or alkoxy groups, are prepared by cyclization of compounds of the formula R1CONHCSSCH2COOR2 (R2 is H or an alkyl or aralkyl group). Cyclization may be effected by heating or by treatment with sulphuric or trifluoro acetic acid. Examples are given of the cyclization with sulphuric acid of S-(benzoylthiocarbamyl) - mercaptoacetic acid, S - (p-methoxybenzoylthiocarbamyl) - mercaptoacetic acid or its ethyl ester, and S-(carbethoxythiocarbamyl) - mercaptoacetic acid. S-(Benzoylthiocarbamyl) - mercaptoacetic acid is prepared by heating a mixture of benzoylisothiocyanate and thioglycollic acid on a steam bath.  S - (p - Methoxybenzoylthiocarbamyl)-mercaptoacetic acid is similarly prepared; by using ethyl thioglycollate instead of the acid, the ethyl ester is directly obtained. S-(Carbethoxythiocarbamyl)-mercaptoacetic acid is similarly prepared from carbethoxyisothiocyanate and thioglycollic acid, but cyclisation takes place spontaneously at the reaction temperature to give the rhodanine (see above).  2 - (Thiobenzoylmethylene) - 2 : 3 - dihydro - 3 - ethyl - benzthiazole is prepared by heating 2-benzoylmethylene - 2 : 3 - dihydro - 3 - ethyl - benzthiazole with phosphorus pentasulphide in dry toluene.  The product may be quaternized with methyl iodide.  Specification 466,269 is referred to.ALSO:Merocyanine dyes of the general formula <FORM:0829644/IV(c)/1> wherein R1 is an aryl, substituted aryl or alkoxy group, R3 is an alkyl, aryl or aralkyl group, Z is -N = or -CH =, n and m are 0 or 1 and D completes a 5- or 6-membered heterocyclic nucleus, are prepared by condensing a heterocyclic nitrogen quaternary salt having a reactive -SR, -CH = CH4-SR (R being alkyl or aralkyl) or acetanilidovinyl group, with the appropriate N-substituted rhodanine.

Title: Improvements in or relating to photographic printers
IPC: G03B27/80
Filed: 1956-12-18
Abstract: 798,738. Photo-electric exposure control. KODAK, Ltd. Dec. 18, 1956 [Dec. 27, 1955], No. 38578/56. Class 40 (3). In a photographic printer employing a fixed exposure time and a variable light intensity, there are provided two alternative exposure times and means for automatically changing over to the longer time when the shorter time gives an insufficient exposure with the maximum light intensity. The printer comprises a light source 12, an iris diaphragm 19 operated by a servomotor 20, a negative carrier 10 for a transparent film 11, a lens L, a pivoted shutter 15 controlled by a spring 17 and a plunger 18 of a solenoid 18<SP>1</SP>, and a transparent or apertured support 14 for light-sensitive printing material 13. The servomotor 20 is connected to an amplifier 23 and an error detector 24 under the control of a standard photo-cell 25 with a reference lamp 26 and a monitor photo-cell 27 which detects the diffuse light transmitted by the film 11. When a switch 29 is closed, relay CR3 is energized and reference lamp circuit is closed through a resistance 30 and a short timer 50 operated through a delay relay 48. If the shutter 19 is opened fully without a balance being reached, quadrant 22 closes a switch 61 of a relay CR1 which brings resistance 31 into the reference lamp circuit and reduces the lamp brightness, and changes over to a longer delay relay 47 and long timer 51. As the plunger 18 is moved to operate the shutter 15, it moves a contact 53 to shunt a relay CR2 and so to open a contact 56 and at the same time closes a contact 57 so that when the plunger returns to its normal position the relay CR3 is de-energized. Switch 36 provides a control for a relay CR4 as an alternative to switch 29 and relay CR3. Specification 660,099 is referred to.

Title: Control and monitoring means for oil or gas burners
IPC: F23N5/20
Filed: 1969-08-01
Abstract: 1,207,649. Burner control. LANDIS & GYR A.G. 1 Aug., 1969 [7 Aug., 1968], No. 38746/69. Heading F4T. A control and monitoring system for oil or gas burners comprises an electrically heated bi-metal strip 1 which controls first and second sets of contacts 3, 2, and an electromagnetic control 17 which is controlled by a photoresistor 15, a lever 9 being provided between a fuel supply control contact spring 4 and an armature 10 of the electromagnetic control 17, the lever 9 when the armature 10 is attracted, preventing the contact spring 4 firstly making contact with a starting supply contact spring 5 and secondly separating it from a control contact spring 7, or, after the bimetal strip 1 has tripped the second set of contacts 2 and the armature 10 is attracted, it separates contact spring 4 from contact spring 7 and holds the former in engagement with spring 5 while the bimetal strip 1 returns to its rest position. In operation, the switch 12, Fig. 2, is closed by a thermostat, supplying power to the blower 13, ignition coil 14 and heater coil 1. The bi-metal strip 1 bends, moving contact springs 4 and 6 together against contact 5 which energizes the valve 19 to supply fuel for starting the burner. On ignition, the photo-resistor resistance drops so that the electromagnetic control 17 receives sufficient current through the diode 16 to attract the armature 10, which traps lever 9 by means of hook means or roughened contact surfaces, and thus breaks the contact between 4 and 7, cutting off the current to the heater 1 allowing the bi-metal strip to cool and return to its original position together with the linked contacts 6 and 8, the latter of which cuts in the main fuel supply valve 20. If the flame goes out, the resistance of the photo-resistor 15 increases, reducing the current through the electromagnetic coil 17 causing armature 10 and lever 9 to be released, and contact 4 moves out of contact with contacts 5, 8, cutting off the fuel supply via valves 19, 20, and into contact with contact 7, re-commencing the ignition procedure. If no flame is produced, heater 1 is energized via contacts 4, 7 for longer than the normal period, so that contacts 3 are triggered cutting off power to the control circuit and causing the warning light 21 to come on. The contacts 3 lock in this position and have to be re-set manually. A control element 18 (a capacitor or a transistor amplifier) in parallel with the photo-resistor 15 provides a current surge through the coil 17 when switch 12 is closed, thus attracting armature 10. If the resistance of the photo-resistor is too low, due to ageing, high ambient temperature or stray light, the armature 10 remains attracted and prevents movement of the lever 9 and hence the contact 4, and current is supplied to the heater 1 until contacts 3 are switched.
