Abstract: The present invention describes a method for selecting a preferable codec mode for a connection between a first communication device (UE1) and a second communication device (UE2), where the devices communicate via a network. An element in the network observes a quality of said connection. The quality is based on a data error level of network resource. Based on the observation the network element judges a preferable operational mode of the codec, from a group of operational modes of the codec. The preferable codec mode is based on the quality level of the connection. In the preferred embodiment, if a Radio Network Controller (RNC) observes congestion by observing Real-Time Protocol (RTP) header information, the RNC judges a lower codec mode for the connection. The lower mode for the connection is judged if there is at least one gap in a sequence of detected packets.

Abstract: The operation of radiography apparatus requires a control system to ensure that the product of the intensity of the tube current with its operating time is constant. This system, employing an electronic circuit, ensures that this product is constant for a wide range of current intensities. A condenser is charged by the voltage produced across a resistance by the operating current. This voltage is corrected according to the intensity of the current by a circuit containing a transistor, which applies a correction during the use of current intensities of 100 milliamperes.

In a pulse amplitude modulating circuit of the type comprising a pair of transistors with their emitters connected together and to ground via the collector-emitter path of a third transistor, to the base of which the one signal is applied while the second signal which comprises a square wave, is applied to the base of one of the pair of transistors so as to drive them both alternately conductive, means are provided to prevent unwanted components at one or other of the input signal frequencies from appearing at the output, i.e. the collector circuit of one or both of the pair of transistors. In one embodiment this is achieved by connecting a pair of such circuits, i.e. T1, T2, T3 and T4, T5, T6 respectively, in parallel, the output being taken from the collectors of transistors T3, T5 connected together. A switching signal is applied from source Vc to the bases of both of the transistors T2, T5 while the bases of transistors T3, T6 are grounded over a capacitor. The emitter circuit transistors T1, T4 are however driven in push-pull by means of a transformer Tr with a centre-tapped secondary. In another embodiment, comprising a single pair of transistors with the base of one driven by switching signals and that of the other grounded over a capacitor (Fig. 3, not shown), the collector circuit of each of the pair of transistors comprises a resistor and the two collectors are connected together via a quartz crystal which is series resonant at the switching frequency. In a further embodiment which is stated to be suitable for use in non-linear servo-control systems, the bases of a pair of input transistors (T2, T3, Fig. 4, not shown) are driven in push-pull from a switching source (Vdc) which may comprise a phase discriminator and D.C. amplifier. A 400 c.p.s. supply is applied to the base of a transistor (T1) common to the emitter circuits via a resistor. The collector circuit of each of the input transistors (T2, T3) comprises a resistor (R1) and is coupled via a capacitor (C4, C5 respectively) to the base of one of a further pair of transistors (T7, T8): these are connected in series to form a subtracting circuit so that the servomotor output, taken from the collector of one of the further pair of transistors (T8) does not contain a 400 c.p.s. component when the 400 c.p.s. supply is equally divided between the input transistors (T2, T3). Each of these has a resistor (R3) connected in the emitter lead which is responsible for a dead space appearing in the input/output characteristic.

Abstract: 1,228,959. Mechanically closing bags. VERENIGDE KUNSTMESTFABRIEKEN MEKOG - ALBATROS N.V. 23 April, 1968 [25 April, 1967], No. 19118/68. Heading B8C. Apparatus for closing the open end of a filled bag has two pairs of movably mounted elements, each pair being adapted to grip the bag mouth near one of the edges and means to exert a force on the pairs after gripping to force them apart and stretch the upper edge of the bag. Pistons rotate arms 1, 1<SP>1</SP> bringing the elements 4, 4<SP>1</SP> into contact with the bag below its top edge, further pressure causes the pairs to slide outwards, towards the side edges. This causes rollers 7 coupled to the elements by rods 9 to move downwards and expel the air in the bag. The arms 1, 1<SP>1</SP> move away from the bag, the pairs being locked in their extreme outward position by a ratchet bar 10 engaging a spring loaded pawl in a guideway 12. The pawl is released by a cable 17, 17<SP>1</SP> when the arms are in the open position. The elements 4, 4<SP>1</SP> can be biased towards their inner position or a shaft with ends 16, 16<SP>1</SP> can be torsioned to rotate the arms 8, 8<SP>1</SP> and the roller 7 upward (Fig. 1) thereby returning the elements to rest. The whole apparatus can be mounted on a carriage to move with the bags when these pass continuously through the machine. The length of the clamping elements 4, 4<SP>1</SP>, in a direction parallel to the open bag seam can be varied in order to deal with bags of different sizes.

Abstract: 1,232,331. Sheet forming. LEBOCEY INDUSTRIE. 28 Aug., 1969 [25 Nov., 1968], No. 42903/69. Heading B5A. A sheet forming press comprises an upper fixed platen 3, carrying a chamber element 1 and attached by columns 4 to a fixed base 18, and a lower reciprocable platen 5, upon which is mounted by means of compression spring 7, a chamber element 6. The lower platen is reciprocated along columns 4 by main jack 13 and auxiliary jack 15 and carries adjustable rods 9 adapted to engage counter pressure jacks 11, 12 mounted upon platen 3. Located with chamber element 1 is a forming or preforming plunger 2 and located with chamber element 6 is a mould 8 provided with a sharp bevelled edge 8<SP>1</SP>. In operation, the lower platen is raised by the main jack until rods 9 engage rods 11 of counter pressure jacks 12 to which hydraulic fluid has been supplied. In the position the element 6 engages the element 1 to clamp the sheet to be formed at a pressure determined by the degree of compression of springs 7, which compression is dependent in turn upon the adjustment of rods 9. The plug 2 is then lowered to prestretch the sheet, the sheet then being transferred by suction or blowing to the mould 8. Finally fluid is released from the counter pressure jacks and the auxiliary jack is actuated to lift the mould 8 a small amount relative to the element 6 thereby severing the formed article from the excess sheet material. The platen 3 is then lowered, the formed article removed and the process repeated.
