Title: Penicillanic acid derivatives
IPC: C07D499/42
Filed: 1971-01-20
Abstract: 1312554 Epimerizing penicillins BEECHAM GROUP Ltd 12 Jan 1972 [20 Jan 1971] 2736/71 Heading C2A A penicillin having the general Formula VIII wherein R is an organic or inorganic cation or an esterifying organic radical and R<SP>1</SP> is an alkyl, aryl, aralkyl or heterocyclic group, is epimerized to an equilibrium mixture of the 6-α- and 6-#- epimers thereof, having the respective structures by treating a solution of the penicillin with a base. The compound (VIII) may be initially in the form of its 6-α- or 6-#-epimer or a mixture thereof, and the treatment with base establishes an equilibrium between the two forms, the position of which is governed by the particular base and solvent employed and also the steric properties of the 6-substituent group R. The process is especially directed to conversion of the biologically poorly active 6-α-epimer into the antibacterially active 6-#-form. The latter may be separated from the equilibrium mixture by fractional crystallization or chromatography, e.g. on silica with elution with a chloroformether mixture. The preferred base used in the process is 1,5- diazabicyclo(4,3,0)-non-5-ene, or else sodium ethoxide, potassium carbonate or triethylamine may be used. The solvent for the penicillin may be benzene, chloroform, dimethylsulphoxide, methylene dichloride, acetone, nitromethane, ethanol or methanol. The group R in the formulae above may be an alkali metal cation or an organic cation and may be the same as the cation of the base employed. Alternatively, R may be an easily removed esterifying group, e.g. benzyl, p - methoxybenzyl, methoxymethyl, methyl, phenacyl, trimethylsilyl or tributyltin. The epimerization is usually carried out at room temperature. The starting penicillin may be prepared by reacting 6-aminopenicillanic acid, or a suitable salt or ester thereof, with an aldehyde R<SP>1</SP>CHO. The #-epimer produced may be subsequently de-acylated, e.g. by treatment with an acid such as p-toluenesulphonic acid, to give the corresponding acid-addition salt of 6#-aminopenicillanic acid or its ester, which may then be re-acylated to introduce a different R<SP>1</SP> group as a 6-position substituent.

Title: Forging manipulator
IPC: B21J13/10
Filed: 1970-04-30
Abstract: 1317301 Forging manipulators DAVY & UNITED ENG CO Ltd 19 April 1971 [30 April 1970] 20761/70 Heading B3H A forging manipulator has a carriage driven by a motor 14, a peel driven by an hydraulic piston.cylinder unit 22, a power source to drive the motor and a second power source to operate the unit 22 and simultaneously supply further power to the motor to compensate for the reaction force of the peel movement against the carriage. During the forging press operation, when the dies are closed, a valve 34 is closed so that the power source pump 30 drives the motor 14 and the peel unit 22 in series so that the peel moves on the carriage in the opposite direction to the carriage to remain stationary in space. After the press stroke the valve 34 is opened and a valve 32 closed. The second power source 33 now drives the unit 22 and supplies power to the motor 14 through a check valve 37. The valves 31, 35 are operated simultaneously to stop or reverse the movement of the carriage and the peel. The power source 33 assists the power source 30 to drive the carriage during movement of the carriage and peel in the same direction to compensate for the reaction force and hence keep the carriage speed constant. The peel may move slightly during forging to allow for elongation of the workpiece.

Abstract: The invention includes a mostly conventional digital television system (2000) to transmit compressed digital signals. A multiplexer (2004) receives a plurality of further input signals, assembles one or more transport streams and transmits compressed digital signals to a transmitter (2008) of the broadcast centre via linkage (2010). The transmitter (2008) transmits electromagnetic signals via uplink (2012) towards a satellite transponder (2014), where they are electronically processed and broadcast via notional downlink (2016) to earth receiver (2018). The signals received by receiver (2018) are transmitted to an integrated receiver/decoder (2020) connected to the end user's television set (2022). The receiver/decoder (2020) decodes the compressed MPEG-2 signal into a television signal for the television set (2022). A conditional access system (3000) is connected to the multiplexer (2004) and the receiver/decoder (2020), and is located partly in the broadcast centre and partly in the decoder. It enables the end user to access digital television broadcasts from one or more broadcast suppliers. A smartcard, capable of decrypting messages relating to one or several television programmes sold by the broadcast supplier, can be inserted into the receiver/decoder (2020). Using the decoder (2020) and smartcard, the end user may purchase commercial offers in either a subscription mode or a pay-per-view mode. A number of features of particular interest are disclosed, involving the randomization of EMMs, mixing parameter length and identifier on EMMs and the like to save space, dynamic allocation of bandwidth for specific EMMs, and the STM being separate from the SMS.
