Title: Open circuit protection system for a multiple channel transformer probe
Inventor: TURNER NIGEL PHILIP
IPC: G01D5/20
Filed: 2009-03-18
Abstract: A transformer probe for sensing movement of a body of magnetic material comprises a magnetically energisable pole piece 11 and a sensing circuit comprising a primary electrical circuit 10. The primary circuit has a portion, remote from the pole piece, which forms first 14 and second 16 transformer primary coils, with two output circuits each comprising a secondary coil, inductively coupled to the corresponding primary coil via a transformer core and terminated by a load resistance, and means for measuring output signals from the secondary circuits. An additional inductive coupling is connected across each primary coil; these have lower impedance than their corresponding primary coils, and, as a result, an open circuit condition within one of the output circuit does not significantly affect the voltage across the first and second primary coils. The coupling may consist of shorting turns 30, 31 wound around the primary coils. The output in each output channel is therefore substantially unaffected by faults in other output channels.

IPC: G06Q40/00
Filed: 2009-06-25
Abstract: A method for providing decision support systems using customer clustering comprises obtaining customer transaction data (e.g. internal-external customer transaction data, credit card information, customer funds ( income)), and categorising it. The categorised customer transaction data is analysed to identify patterns among the data. The identified patterns are used to isolate a selected number of behavioural factors. The customers are grouped into population segments based on the behavioural factors. Any non-linear transaction data may be analysed using a Hidden Markov method. The behavioural segments may be visually presented in a graph (Fig. 3). The decision support system may be used to provide more directed and accurate offers to customers thus improving the customer experience.

Title: Process for the manufacture of new aromatic n-amino-alkyl-amino-aldehydes and derivatives thereof
IPC: C07C47/56
Filed: 1928-04-03
Abstract: 288,972. I. G. Farbenindustrie Akt.- Ges. April 16, 1927, [Convention date]. Aromatic N-aminoalkylamino-aldehydes are prepared by (1) treating an aromatic aminoalkylamino compound having a free pposition with formaldehyde in the presence of an aromatic hydroxylamine compound and decomposnig the resulting anhydro body with alkali; the hydroxylamine compound may be formed in situ; (2) oxidising in the presence of an arylamino compound an aromatic aminoalkylamino compound containing, or capable of acquiring in the course of the reaction, a methyl, methylol or isoallyl group in the pposition, and decomposing the resulting anhydro compound with alkali; (3) introducing the aminoalkyl group into the primary or secondary amino group of an aromatic aldehyde by the usual alkylation methods. The oily products are useful in the manufacture of therapeutic substances. According to the examples, (1) N- diethylaminoethyl-p-aminobenzaldehyde is prepared by reducing 4-nitrotolune-2-sulphonic acid with zinc dust to the hydroxylamine compound, adding formaldehyde and N-diethylaminoethylaniline, and after salting out. the anhydro compound, heating it with caustic potash; in the same way, N-diethylaminoethyl-o-chlor-p-aminobenzaldehyde is obtained from N-diethylaminoethyl-m-chloraniline, and N-diethylaminoethyl-mmethoxy-p-aminobenzaJdehyde from N-diethylaminoethyl-o-anisidine; (2) N-methyl-diethylaminoethyl-p-aminobenzaldehyde results when formaldehyde and N-diethylaminoethyl-meth-ylaniline are added to 4-hydroxylaminotoluene-2- sulphonic acid, and the anhydro body salted out and decomposed with caustic potash; instead of the bydroxylamino compound, 4-nitrotoluene-2- sulphonic acid, hydrochloric acid and iron filings may be present; the same product is also obtained by adding 4-aminotoluene-2-sulphonic acid and potassium dichromate solution to a hydrochloric acid solution of diethylaminoethyl-methyl-aniline containing formaldehyde, and heating the anhydro compound with alkali; (3) N-methyl-(adimethylamino-gamma-methylpropyl)-p-aminobenzaldehyde is formed by heating N-methyl-p-aminobenzaldehyde with alpha-dimethylamino-gamma-chlorbutane (see Specification 274,058), and N-diethylaminoethyl-o-aminbenzaldehyde by interaction of o-aminohenzaldehyde and diethylaminoethyl chloride.

Patent GB-570590-A (GB)
Title: Improvements in or relating to the manufacture of vinyl resin filaments
Filed: 1943-06-24
Abstract: Artificial elastic filaments are produced by dry-spinning a solution of a vinyl resin containing one or more plasticizers or elasticisers in an amount between 25 per cent to 45 per cent based on the combined weight of the resin and elasticiser.  The solution is extruded into an evaporative atmosphere and the filaments are preferably withdrawn therefrom with as little tension as is consistent with a successful spinning operation, although higher tensions are permissible. Preferred vinyl resins are the copolymers of vinyl chloride and vinyl acetate and their chlorinated derivatives and suitable solvents therefore are acetone and ethyl acetate.  The elasticisers are organic liquids having high boiling points and having one or more functional groups, namely, ether, ester, ketone or aldehyde. Specified elasticisers are tripropionin, o-nitro-diphenyl oxide, n-butyl-p-toluene-sulphonate, n - butoxyethyl salicylate, dibutyl phthalate, diamyl phthalate, dibutoxyethyl phthalate, dibutyl adipate, di-isobutyl adipate, dibutyl sebacate, triethylene glycol-di-2-ethyl butyrate, triethylene glycol-di-2-ethyl hexoate, dimethoxy tetraethylene glycol and methoxy tetraethylene glycol benzoate.  Small amounts of other compounds which increase the extensibility and tensile strength of the filaments such as Coprol B, indene-dimer, phenyl stearate and methoxyethyl oleate may be added to the spinning solution as well as stabilizers for the resin and counter-odorants for the elasticiser.  The filaments or threads may be employed in the manufacture of wrapped or unwrapped threads, fabrics, garters, girdles, straps, hosiery, bathing suits, &c., and combined with other textile threads in the production of special effect fabrics.  The threads may be dyed with dyestuffs which are soluble in the elasticiser, e.g. oil-soluble dyes or suspension dyestuffs, such as 1 - amino - 2 - methylanthraquinone, dimethylamino - anthraquinone, or Chinoline Yellow.  Specification 560,660 is referred to.

Filed: 1930-04-01
Abstract: 343,368. Printing-machines. FOSTER & SONS, Ltd., J. and BRADSHAW, R., Soho Foundry, Preston. April 1, 1930, No. 10360. [Class 100 (ii).] Folding paper.-The impaling pins or needles 12 of a rotary folding-cylinder 7 are mounted in holders 13 which screw into needle bars 8, 9 mounted to move in grooves 10, 11 in the cylinder, the needles 12 operating through apertures in cover plates 27, 33 which when removed permit of access to the needles and their operating means from outside of the cylinder. The bars 8, 9 are secured by screws 16, 17 to arms 18, 19 on a rock shaft 20 which is operated by the action of a cam on a bowl 23 on a lever 22 freely mounted on the shaft 20. The bar 8 is formed with slots 14, 15, Fig. 3, at its ends, and normally the slot 14 engages a projection on the lever 22 and motion is transmitted to the shaft 20 and to the impaling needles. If it is desired to put one set of impaling pins out of action, the bar 8 is moved to the right and so causes the lever 22 to oscillate idly. A projection 25 on the bar is received in a recess in the cylinder, and the needles are thus held inoperative. The bar 9 is constructed so as to remain in action permanently, the cam-actuated lever 32 being fixed by a screw to the rock-shaft 20.

Title: Improvements in or relating to a.c. electric circuit-breakers of the gas-blast type
IPC: H01H1/38
Filed: 1940-06-17
Abstract: 542,728. Gas-blast switches. REYROLLE & CO., Ltd., A., AMER, D. F., and WEBB, W. H. June 17, 1940, Nos. 10464/40 and 6532/41. [Class 38 (v)] A gas-blast switch comprises a pair of fixed arcing contacts, a nozzle of insulating material or of conductive material insulated from the contacts, arc-initiating contacts one of which is in the form of a rod or tube disposed substantially in alignment with or parallel to the arc-gap between the fixed arcing contacts, whilst the other is constituted by a group of spring contact members co-operating therewith, and means whereby a blast of deionizing gas is caused to flow through the nozzle and to transfer to the arcing contacts the arc initially formed at the arc-initiating contacts, the arc being arranged when transferred to extend through the nozzle. In one embodiment, Fig. 4 (not shown) a single-break arrangement is substantially the same as the lower break of Fig. 2 of Specification 542,722, the invention also being applied to the modification of that figure employing fixed spring contacts and a movable arc-initiating tube surrounding and in contact with a fixed arcing contact rod. In Fig. 1 which is the same as Fig. 1 of Specification 542,920, a metal casing A houses an insulating nozzle B above which is a spider carrying one fixed arcing contact E. The contact D which serves as the other fixed arcing contact and as arcinitiating contact, co-operates with spring contacts C which engage it on either side and are mounted on a piston C<SP>1</SP> which, in opening circuit, is forced into a lateral branch A<SP>1</SP> of the casing A by the blast-pressure so as to leave the casing A clear for an uninterrupted gasflow. The casing A may be surrounded by insulation and an outer earthed metal casing which may be arranged to provide a tortuous path for cooling the exhaust gases. Instead of a rod contact D, a tubular contact may be employed, or a tubular arc-initiating contact may have a central rod serving as arcing contact.

IPC: D01H1/40
Filed: 1956-04-06
Abstract: 825.215. Textile spinning &c. appartus. COURTAULDS Ltd. April 5 1957 [April 6, 1956], No. 10539/56. Class 120(2) To assist starting up in ring or cap spinning or twisting apparatus by disposing of the loose end of the yarn, thread guides are provided in substantially the same plane as a grooved pulley 13: the first is carried by a driving member 7 and the second by a member 12 which is stationary or constrained to accelerate on starting more slowly than the driving member, and both may take the form of peripheral notches 18, 19 respectively. On starting, rotation of the member 7 causes the thread to be dragged across the barrel of the bobbin and into the groove of the pulley 13: the pulley is thus rotated to withdraw the thread from a pneumatic collector 17. The thread is then severed where it crosses a cheek 6 of the bobbin and the loose end is wound up by the residual momentum of the pulley. In another form, the boss 11 on which the pulley is mounted is carried by the rotating member 7 so that, although the pulley is free to rotate on the boss, it normally rotates with it and the member 7. With this form, the thread is not cut so that it winds on the pulley to form a transfer tail.
