Abstract: The invention relates to a method of delaying uplink acknowledgement in packet data transmission between a mobile communication device, MS, and a mobile communication network, NW. In the method, at least one temporary block flow, UL TBF, DL TBF, is set up, in which data is transmitted in packets in one or more packet data traffic channels, PDTCH, in a first direction from the mobile communication device, MS, to the mobile communication network, NW. At the end of the transmission in the block flow, information is set in the last packet (307) to be transmitted about the end of the block flow, wherein the receiver of the packets acknowledges (312) the reception of the packets. In the method, after the end of the transmission of packets in said first direction, a determined time is waited until an acknowledgement (312) is transmitted. If, during the waiting time, the mobile communication network, NW, detects a need for transmission of packets in the second direction from the mobile communication network NW to the mobile communication device MS, at least one packet data traffic channel PDTCH, is set up (311) for data transmission in said second direction.

Abstract: The invention relates to a method for ensuring data transmission security between a first (2) and a second communication device (3) in short-range wireless communication. To set up a secure data transmission connection, the communication devices (2, 3) conduct a key exchange stage to generate at least one shared key (K) between the communication devices. After said key exchange stage at least a first (c1) and a second check string (c2) is formed, said strings being based at least on a unique short random string and on the keys (K1, K2) generated in each communication device at said key exchange stage. Thus, the security of the connection that is set up is ensured by comparing the correspondence of said check strings (c1, c2). The invention also relates to a communication system and a communication device, in which the method will be applied.

The arrangement of digit pairs such as 27, 28 which extend over one side of each of planes 7 to 14 is shown in laid-out form in Fig. 2, adjacent digit pairs being alternately straight and crossed where they extend from any one plane to the next. Each digit conductor is connected to earth at both ends through characteristic impedances Z 0  and is connected at a midpoint M to a differential sense amplifier 20, 22, 20<SP>1</SP> or 22<SP>1</SP>. Each amplifier is connected to a digit pair and provides an output only if read out signals in the two conductors of the pair are substantially different. A word is read out by closing a switch 48, 49, 68<SP>1</SP>, 69<SP>1</SP> so that a read driver 46 or 66 is connected to a column word conductor through a coupling transformer 44, 45, 64 or 65.

A device for applying and removing a tyre to and from a wheel rim, comprises a rotatable support 7, pneumatically operated clamping means 9 for clamping a wheel on the support, and a tool bracket 31, 32 vertically movable above the support and carrying a tyre pressing roller 34 and a tyre lever supporting bracket 33. In Fig. 1, three radial arms 8 each carry a movable clamping element 9, (one only shown) biased outwards by springs 27 and movable inwards to grip a wheel rim by pulling members 13, 14 attached to a coupling 15 which is moved vertically downwards by a pneumatic jack 17. Jack 17 is supplied with compressed air through a conduit 19, which carries sections 29, 30 each actuating a lever system 71, 22, 23 supported on each arm 8. In use, a wheel rim is clamped by elements 9 and a tyre lever mounted in bracket 33 is used to lever off the upper bead of a tyre, while the support and wheel are turned by a motor driving gear-wheel 6. A pneumatic jack 40, via rods 39, 38, is then used to lower conduit 19, which lifts rods 71 whose ends 28 push the tyre off the clamped rim. In applying a tyre, the rim is clamped and rotated and the grooved periphery of roller 34 is engaged over the rim so that its lower face pushes the beads over the upper flange of the rim. Fig. 2 (not shown) illustrates a lever mounting bracket 54 and roller 55 mounted on an arm 56, which is rotated about a horizontal axis to bring either bracket or roller into use. A pneumatic jack 49 actuates wheel clamps as above, and a cylinder 53 moves the tool arm 56 vertically. When the forked bracket 54 is downwards, for levering a tyre bead off a rim, downward movement of the tool bracket is limited by a rotatable pawl, actuated by turning arm 56, engaging under a ring 63. With roller 55 downwards for pushing beads over a rim, downward movement is limited only by ring 63 engaging bush 64.

The Specification describes the preparation of many penicillins of the above formula, of which the following are typical: 6 - [α - hydroxy - α - (2 - thienyl) acetamido], 6 - [α - hydroxy - α - (3 - furyl) acetamido], 6 - [α - hydroxy - α - (N - phenyl - 2 - pyrrolyl) acetamido] and 6 - [α - bydroxy - α - (4 - pyridyl) acetamido] penicillonic acid, and the Specification also describes the production of D- and L-diastereoisomers of the penicillins as well as mixtures of the two optically active forms. Pharmaceutical compositions comprise penicillins of the invention and conventional additives. Ethyl α-2-thienylglyoxylate is prepared by reacting thiophene with ethyl oxalyl chloride. It may be hydrolysed to produce α-2-thienylglyoxylic acid which may be converted to α-2- thienylglyoxylic acid chloride by treatment with thionyl chloride. α-2-Furylglyoxylic acid chloride is prepared by reacting furan with oxalyl chloride. α-(2-Thienyl) glyoxylic acid is prepared by reacting 2-acetylthiophene with selenium dioxide. 2-Pyrrolylglyoxylic acid chloride is prepared by reacting pyrrole with oxalyl chloride. N-Phenyl-2-pyrrolylglyoxylic acid chloride is prepared by reacting N-phenyl-pyrrole with oxalyl chloride. The N-methyl compound is prepared similarly from N-methyl pyrrole.

Abstract: 1,054,172. Freeze drying apparatus. LEYBOLD - HOCHVAKUUM - ANLAGEN G.m.b.H. May 8, 1964 [May 10, 1963], No. 19355/64. Heading F4G. A freeze drying apparatus comprises a tank 1 spacedly housing a movable vessel 2 internally divided by a partition 5 with openings 21 into an upper drying chamber wherein the material 30 to be dried in bottles 9 is mounted on heated plates 8 on a removable carrier 11 and an openbottomed area encircling an ice condenser 16. The tank is evacuable by a connection 26 to a pump (not shown) and is closed by a hinged cover 3 for insertion and extraction of the carrier 11. The cover houses a pressure gauge 7 and a fan 4 which circulates air from tank 1 over the condenser, through the openings 21 in the partition 5 and non-aligned openings 21 in a closure plate 12 provided in the chamber above the partition, about the bottles 9 to freeze the material therein and then redelivers air through the space 32 between the vessel and tank back to the condenser. Relative movement between the tank and drying chamber is achieved by a vertically movable column 13 so that the plate 12 may rest on the partition 5 to prevent further circulation of cold air by isolating the drying chamber from the evacauting means and condenser. This allows heating of the material and evacuation of the chamber for sublimation and also allows the partition 5 and plate 12 to act as a radiation shield between the material and condenser.
