Patent GB-8505199-D0 (GB)
Title: Extrusion control
IPC: B29C48/285
Filed: 1985-02-28
Abstract: @ An extrusion process is controlled by feeding the material to be extruded from a supply station (5) to an extruder (1) and repeatedly weighing the supply station to calculate the throughput of the extruder. The initial line speed necessary to produce a predetermined weight/metre of extrudate is calculated and the line speed is adjusted accordingly. Subsequently, the throughput and the line speed are increased simultaneously, such that the weight/ metre is maintained substantially constant until any one of a plurality of parameters such as line speed, screw speed, motor load current, extrudate temperature, melt pressure, etc reaches a predetermined maximum value. Thereafter either the line speed or extruder throughput is adjusted such as to maintain the weight/metre of the extrudate substantially constant at the desired value.

Title: Radio data system receivers
IPC: H03J1/00
Filed: 1987-08-24
Abstract: Push button (P1 - P4) are associated with read-only stores RO1 - RO4) which store PI (programme identification) codes corresponding to the selections programmed in by the user. Corresponding read-write stores (RW1 - RW4) store current PI codes; if the PI code associated with the programme currently received changes, the new code is written in the corresponding read-write store. ON (other networks) data decoded by the radio data system is compared (D1, D2) with stored PI codes. If there is an exact PI code match with a PI code in a read-only store (RO1 - RO4) a corresponding list of alternative frequencies (e.g. MAF2) for the programme currently received is updated. If there is a generic PI code match (signifying related programmes) with a PI code in a read-write store (RW1 - RW4) a corresponding list of alternative services (MAS1 - MAS4) is updated. Repeated pressing of a button (e.g. P2) selects in turn the alternative services identified in the corresponding list (MAS2). Alternative frequencies are selected automatically when received signal strength deteriorates.

Title: Circuit board and apparatus for recognizing the position of circuit board
IPC: G01N21/88
Filed: 1991-10-30
Abstract: In a circuit board, a fiducial mark (2) of the same material as that of a circuit pattern is formed on a main surface of a board (1) on which the circuit pattern is formed, and it is coated with a solder resist film (3). According to this circuit board, it is possible to carry out position recognition by irradiating infrared rays without exposing the fiducial mark (2), so that oxidation of the fiducial mark (2) or attachment of solder thereto are prevented. An apparatus for recognizing the position of a circuit board includes means (22) for picking up the image of the surface of a circuit board (20), means (23) for recognizing the position of the circuit board (20) from thus obtained image, and means (21) for irradiating infrared rays toward the circuit board (20). In another arrangement the apparatus is used to detect the position of part of the wiring pattern rather than a fiducial mark. FIG.6 <IMAGE>

Patent GB-9400385-D0 (GB)
Title: A transmitter for a remote control group
IPC: G08C19/28
Filed: 1994-01-11
Abstract: A transmitter (2) for a remote control group can learn a code embedded in a radiation signal received from another transmitter (2) of the same group. A non-resettable teach status switch (16) sets an instruction which is transmitted with every time a code is transmitted. This instruction may be recognised by a receiving transmitter and instructs operation of the receiving transmitter. The information may be to indicate whether or not the code may be learned by the receiving transmitter and therefore, a transmitter may be set as a "learn only" transmitter or as a "learn and teach" transmitter. It is only necessary for the user to press the relevant transmit button on each of the transmitters. This is because the controller (20) of the transmitter monitors a radio receiver (23) every time the transmit button is pressed. In addition, it delays transmission of a code when a transmit button is pressed so that it can listen to the radiation receiver (23). There are two delay periods, the first for detection of a signal, and the second longer period for recognition of a valid code. The second period is not used if no signal is detected in the first period. <IMAGE>

Title: Mechanical link arms
IPC: B60S1/24
Filed: 1995-11-17
Abstract: A mechanical link arm 1 for connecting together two rotary windscreen wiper shafts comprises a hollow tube 2 of plastics material integrally formed by gas injection moulding with a socket connector 3, 4 at each end. Each socket connector 3, 4 closes off the end of the tube 2 and serves for connection to a complementary ball connector on an associated one of the windscreen wiper shafts. Such a link arm is produced in one piece in a single fabrication step, and is therefore capable of being manufactured at significantly less cost than a conventional link arm. Furthermore the link arm is fabricated from a suitable plastics material so as to be both strong and light, and in addition so as to permit some flexing of the arm in the event of a mechanical overload so that such a mechanical overload will be less likely to cause burning out of the wiper motor. <IMAGE>

Title: Method for preparation of cleaved polipeptides
IPC: C12N9/52
Filed: 2002-09-12
Abstract: A gram-negative bacterial cell is described that is deficient in a chromosomal gene present in a wild-type such cell which gene shares at least 80% sequence identity with the native sequence of the yfcK gene and encodes an aminopeptidase. Alternatively, a gram-negative bacterial cell is deficient in a chromosomal gene present in a wild-type such cell which gene encodes an aminopeptidase that shares at least 80% sequence identity with the native sequence of aminopeptidase b2324. Either of these types of cells, when comprising a nucleic acid encoding a heterologous polypeptide, produces an N-terminal unclipped polypeptide when it is cultured and the polypeptide recovered, with virtually no N-terminal clipped polypeptide produced as an impurity. Conversely, a method is provided for cleaving an N-terminal amino acid from a polypeptide comprising contacting the polypeptide with an aminopeptidase sharing at least 80% sequence identity with the native sequence of aminopeptidase b2324.
