Abstract: A method of generating a transaction card includes receiving, at one or more servers, an input identifying a card spending limitation based on the input, receiving, at the one or more servers, an input identifying one or more usage constraints, generating, a usage rule set based on the one or more usage constraints, generating a transaction card based on the spending limitation and the usage rule set, and sending the transaction card to a consumer. The usage rule set comprises executable code for verifying that the usage constraints are met by one or more transaction parameters, and the transaction card is only valid when the usage rule set is satisfied.

Abstract: A method of providing a loan credit to a customer before the customer requests the loan comprises obtaining, by a server, personal information for a customer by a credit broker application executing on the server, executing, on the server, a plurality of lender approval models using the personal information for the customer as input to each lender approval model, where each lender approval model is stored on the computer system in a byte code format as part of a private blockchain system, generating, by the server, a plurality of loan, evaluating, by a credit broker application executing on the server, the plurality of loan approvals based on a credit broker rule set, selecting, by the credit broker application, one of the loan approvals by the credit broker application, and presenting information to the customer comprising the terms of the selected loan approval by the credit broker application.

Abstract: A method of anonymously matching a buyer to a seller comprises receiving, at a server from the buyer, an approval model in byte code format, encrypting, by the seller, customer data to produce encrypted customer data, executing, by the server, the approval model using the encrypted customer data as an input, generating, by the server from the executed approval model, a transaction response, determining, by the server, that the transaction response comprises an approval of at least one product, publishing, to the server by the seller, the product lead, receiving, at the server from the buyer, an acceptance of the product lead based on the approval, and sending, by the server, the customer data to the buyer in response to receiving the acceptance of the product lead. The customer data can correspond to a product lead.

Abstract: A novel method for preparing a compound of formula I which comprises of coupling the piperazine derivative of formula II with alkyl halide containing compound of the formula III by heating in solvent free conditions or, optionally, in a minimum quantity of non-aqueous suspending liquid, in presence of a catalyst and a neutralizing agent to neutralize the hydrohalic acid.

Abstract: A process for preparation of 7-[D-?-amino-?-(4-hydroxyphenyl)acetamido]-3-(1-propen-1-yl)-3-cepham-4-carboxylic acid viz. Cefprozil of formula (I) igh purity, substantially free of impurities, which comprises preparation of mixed acid anhydride by selecting the sequence and temperature of addition of the reagents and its subsequent condensation with a protected 7-APCA; followed by hydrolysis, isolation and purification to give Cefprozil of formula (I) in the form of a monohydrate.
