Title: Controlling information requests in a communications network to prevent congestion
Inventor: CENTONZA ANGELO
IPC: H04W28/02
Filed: 2007-09-17
Abstract: A method of controlling information requests in a communication system operating in an unauthorised, un-associated mode. e.g. IEEE 802.11 generic advertisement service (GAS) or UMTS home base station or Node B. The system comprises at least one user device 5a, 5b, 5c and an access point 6. The access point 6 receives a first information request from a user device 5a, 5b, 5c, along with a user device identifier, and sets a utilisation indicator. The access point 6 then receives a second information request from a user device 5a, 5b, 5c and checks to determine whether a timer associated with the utilisation indicator has expired. If so, the second information request is processed for response. The utilisation indicator is set according to the degree of congestion so that a user only gets a response to one request within a set time. The utilisation indicator may comprise a timer comprising a GAS traffic indication map (GASTIM) or a GAS comeback delay.

Patent GB-1531687-A (GB)
Title: Method and separator for separating adsorbable hydrocarbons floating on a liquid
IPC: E02B15/04
Filed: 1977-03-10
Abstract: 1531687 Picking up floating matter INSTITUTE FUR TEXTIL-UND FASERFORSCHUNG STUTTGART 10 March 1977 [7 July 1976 10 March 1976] 10283/77 Heading B1D Floating oil is picked up from a body of water by at least one endless band 12' of needle felted polypropylene or other fibrous oleophilic material, which absorbs the oil where it enters the water and after passing round roller 16' lifts the oil to a point where it is squeezed out by driven rollers 13, 14. In Fig. 3 five bands 12' are entrained round rollers 14, 16', 45, the bands being less than 20 cms wide and spaced 1 cm apart laterally, rollers 16' and 45 being grooved to guide the bands. This construction avoids the creasing which a single wide band would suffer. If the oil layer is thin, the oil is mainly squeezed laterally on to the sections of rollers 13, 14 between the bands, and scrapers 49 direct it into vessels 29' which are located in the dotted line positions with edges 50 engaging the rollers and edges 51 engaging the bands. If the oil layer is thick the oil mainly runs down the outsides of the bands, and vessels 29' are located in the solid line positions so that edges 50 direct the oil into them. Switching the vessels from one position to the other could be automatically controlled by an oil sensor. Blades 47 are primarily to remove solids from the bands, but these blades and also edges 51 in the dotted line position of vessels 29' form chambers which catch any oil running down the bands and redirect it into the bands. An alternative blade 47' redirects such oil to where the bands enter the water. In an alternative construction (Figs. 1, 2 not shown), two bands are arranged with their rising runs face to face. Bands are preferably of unmodified polypropylene, alone or mixed with polyester or polypropylene or other plastics rendered hydrophobic by silicon products. Needled felt (without binder) is preferred, but knitted or woven material consolidated by binders may be used. The band may be reinforced by an embedded net or mesh or may be enclosed in a mesh envelope. The device can be mounted on a ship, to pick up oil at sea, or across a stream or in a settling tank for removing oil from machine tool coolant.

Abstract: 430,847. Milling-machines. HOPPE, F. E. O., Rorschacherberg, Switzerland.- (Assignee of Schmidtmann, F. W. ; 3, Kastanienweg, Degerloch, Stuttgart, Germany) April 5, 1934, No. 10300. Convention date, April 5, 1933. [Class 83 (iii)] In a milling-machine having a stationary bed 1 and vertically adjustable spindle-head 6, the overarm 7 carries a bearing member 8 which supports the outer end of the work spindle and which is associated with a vertical brace 11 connectible at 55 to the member 8 and operated by screw and nut mechanism connected to the adjusting means of the spindle-head so that the spindle head and the brace are adjusted in unison. The standard 5 carrying the spindle-head is adjustable along a bed 4. The brace 11 is of box girder form and slides in a stationary guide formed by a channel member 12 and retaining plates 31. For raising and lowering the brace a rack bar secured thereto is engaged by a pinion carried by a shaft which may be rotated from a hand crank 18 through a disengageable coupling 20. The member 12 encloses a threaded spindle 21 connecting with a transversely slidable halfnut operated from a handle 25. The shank of the half nut is mounted on a plate 22 having bearing eyes 23 which fit loosely over the spindle 21. The plate 22 slides with the brace 11 and is re- . tained by guide strips 31. The upper end of the brace carries a nut 32 connected to an actuating ring 55. and coacting with a threaded pin 34 fixedly mounted to the arbor support 8 so that by turning the ring 55 the brace 11 may be locked to the support 8. The main spindle-head 6 is adjusted by a spindle 49 connected by a horizontal shaft 42 to the spindle 21 so that when the nut segment is engaged the brace 11 is moved synchronously with the spindle-head during vertical adjustment thereof. If the brace is not -required the nut 32 and the halfnut 24 are both disengaged and the brace lowered by means of the rack bar. To relieve the arbor from lateral strain a counter-support 52 of triangular form is swung about a pivot 53 into an operative position wherein a projecting rib engages a corresponding groove 59 in the arbor support 8.
