Title: Universal identifier for suppliers in payment system
Inventor: CLAYTON ROBERT
IPC: G06Q20/00
Filed: 2009-11-24
Abstract: A system, method and program enables a data processing framework to process financial transactions, and creates a business to business trading partner network. A payment management computer is used to receive a supplier enrolment file from a buyer, validate the file and send an enrolment invitation to the supplier. The payment management computer recognises that different enrolling suppliers are actually members of the same corporate organisation and associates the suppliers by using a universal identifier UID. This eliminates duplicate supplier information. The universal identifier can be used to form relationships and hierarchies, such as interrelated departments, locations and subsidiaries of the same supplier, in order to increase efficiency of the trading partner network.

Title: The dealkylation of polyalkyl alicyclic ketones and alcohols
Filed: 1947-04-15
Abstract: Alicyclic alcohols or ketones having at least two alkyl substituents are dealkylated to alicyclic alcohols or ketones having fewer alkyl substituents by hydrogenolysis with hydrogen in the presence of a hydrogenation catalyst at 150-350 DEG  C. Isophorone and 3,3,5-trimethylcyclohexanol may be converted to saturated alicyclic derivatives having fewer methyl substituents such as 3,5-dimethylcyclohexanone and hexanol.  Catalysts include Ni, Co, Fe, Pt, Pd, on supports of alumina, silica, or clays, and oxides of metals such as Cr or Mo.  Hydrogen partial pressures may be from 1 atm. to 3000 p.s.i.  Reaction may be effected in liquid or vapour phase with the catalyst in motion or fixed.  In examples, a rocking hydrogenation bomb is charged with isophorone and Raney nickel, and hydrogen added, temperatures varying from 150 DEG  C, at which little demethanation occurs, to 300 DEG  C., giving 3,5-dimethyl-and 3-methyl-cyclohexanol or cyclohexanone, depending on the hydrogen partial pressure.  Tetrahydroisophorone also formed may be recycled or itself reacted with hydrogen to yield further dealkylation products.

Title: Improvements in or relating to dynamo-electric generators
IPC: H02K19/34
Filed: 1926-04-17
Abstract: 250,972. Kesselring, F. April 18, 1925. [Convention date]. Controlling lighting systems; charging batteries; regulation, automatic.-The invention relates to a generator, such as is used on vehicles, for giving substantially constant volts at varying speeds, combined with an ignition device having its armature coaxial with the main generator armature and its field system magnetically in parallel with that of the generator, both fields being excited from the generator armature. The Specification, as open to inspection under Sect. 91, (3) (a) contains a claim for so arranging. electromagnetic auxiliary devices in general in a constant voltage generator that their magnetic circuits are in parallel with the circuit of the flux of the generator or of a " partial " flux thereof by being interlinked by a winding producing the main or " partial "flux, and exemplifies the auxiliary devices as switches or regulators in the exciting circuits. Fig. 2 (Cancelled) shows a switch 16 for charging a battery 8 from the main brushes 5. 6 at a limiting generator speed. The iron switch armature 13 is pivoted to an extension of the yoke 12 of the pole 1 and its free end faces an extension 11 of the pole-shoe, forming a flux-shunt path. The insulated contact 16 is connected through a coil 18 on the switch to the brush 5 and the switch is normally held open by a spring 15. At a certain generator speed the pole-shoe attracts the switch arm to close the charging circuit and the flux due to the current in the coil 18 augments the closing force acting on the switch. In Fig. 3 (Cancelled) the application is shown for reducing the generator volts at a limiting speed by inserting resistance 23 in series with the main field coil 9. When the main flux reaches a limiting value, the pole-shoe 11 attracts the switch arm 19 against the action of a spring 20 and inserts the resistance which is normallv short-circuited at 22. A form is also described in which resistance is introduced into a battery-charging circuit when the charging current exceeds a certain value. This subject-matter does not appear in the Specification as accepted.
Patent GB-1513823-A (GB)
Title: Safety device for guarded machinery
IPC: F16P3/00
Filed: 1975-03-12
Abstract: The safety device contains a first unit (1) with a closure body which can be fitted to the machine frame, and a second unit (5) which can be fitted to a protection device (7), for example a door, and has a closing part (9). The closing part can be moved from an open position into an off position and into an on position and, in the open position, can be engaged with the first unit and disengaged from it. The closing part operates a switching device (29) when both units are engaged with one another, in such a manner that the voltage is applied to the machine only when the closing part (9) is in the on position. A delay device (30, 31, 32, 34), which can be actuated from the on position into the off position by rotating the closing part (9), prevents displacement of the closing part from the off position into the open position during a time interval in order, for example, to block access to the machine before it stops. The device can be used, for example, on a domestic spin drier. <IMAGE>

Abstract: 1432111 Cameras; diaphragms FRANKE & HEIDECKE GmbH [trading as ROLLEI-WERKE FRANKE & HEIDECKE 7 March 1974 [4 April 1973] 10346/74 Heading G2A and G2J An SLR camera with a TTL metering circuit for controlling the diaphragm has means for completely closing the diaphragm aperture prior to exposure so that spurious light entering through the view-finder can be measured and its effect on the metering circuit compensated for e.g. as in Specification No. 1381994. As shown, when a measuring key (not shown) is pressed a coil 3 is energized and moves from a magnet 1 towards a magnet 2 to operate linkage 7, 8 which moves a diaphragm ring 9 until a pointer 19 thereon strikes a stop 22. Movement of ring 9 closes diaphragm blades 10 to the minimum aperture, and at this point a pin 16 moving in a slot 15 in a stationary ring 14 pivots a member 17 to completely close the aperture. Spurious light is measured and a corresponding signal memorized and then coil 3 moves back towards magnet 1 to open member 17 and to adjust the diaphragm blades 10 until the correct aperture is set, the correct aperture being determined by a bridge circuit (not shown) which takes account of the spurious light signal. Exposure can then be made when desired.

Abstract: A water-treating composition comprises 80 per cent to 96 per cent by weight of a water - soluble molecularly - dehydrated alkali-metal phosphate having an alkalimetal-oxide/P2O5 ratio of from 1.0 to 1.3, 19.98 to 2 per cent of an alkali metal carbonate, bicarbonate or percarbonate or of a mixture thereof, and 0.02 per cent to 2 per cent of an aliphatic monohydric alcohol containing in the aliphatic radical from 6 to 12 carbon atoms.  In one example a finely-divided product containing, by weight, 80.8 per cent sodium hexametaphosphate, 11.8 tetra sodium pyrophosphate and 7.4 per cent sodium acid pyrophosphate is thoroughly mixed with 6 per cent by weight of sodium carbonate and 0,15 per cent octanol. In another example, sodium septaphosphate is mixed with, by weight, 6 per cent sodium carbonate and 0.5 per cent octanol. Both these mixtures dissolve completely and relatively readily in water.  The constitution of the composition is adjusted to yield a pH in 1 per cent solution of 6.7 to 8.0, preferably 7.8, so as to ensure the release of gas when an alkali metal carbonate, bicarbonate or mixtures thereof are employed.  Instead of octanol hexanol, decyl alcohol or dodecyl alcohol may be used. Additional alkalinity adjusting agents such as various sodium and potassium salts including phosphates having an alkali-metal-oxide/P2O5 ratio above 1.3 or mixtures of them may be incorporated in the composition, the quantity being proportioned so as to provide a composition having a pH in 1 per cent solution not exceeding about 8.0.  The particle size of the main phosphate part of the composition should not exceed 50 mesh and is preferably not greater than 100 mesh.
