Patent GB-2082421-A (GB)
Title: Telephone exchanges
IPC: H04M3/46
Filed: 1981-08-06
Abstract: In an office system the control unit has a "ringing" list which is used to determine the most likely recipient of an incoming call. The telephone which has previously cleared the most incoming calls is called first and longest. In the absence of a reply the next telephone in the list is called for a shorter period in dependance upon the difference between the number of incoming calls cleared by each of the telephones and so on down the ringing list. Limits are applied to the difference between the number of incoming calls cleared by each telephone, as stored in the list, so that incoming calls are not left unanswered for excessive time periods in the absence of a reply from the more popular telephones.

Title: Device for joining two or more heat sealable strips of material together
Inventor: FORTHMANN FREDERICK F
IPC: B29C65/74
Filed: 1982-03-26
Abstract: An apparatus for joining two or more heat sealable strips of material, particularly strips of polyester cloth labels, together comprises a support 10a over which the strips are fed and superposed. The superposed strips are directed beneath a backing bar 16 which overlies a slot 14 in the support. A heat sealer block 18 is disposed in alignment with the bar 16 below the slot 14 and it has a heater 20 for heating the entire block including a top face which has a series of strip engaging teeth (24), Figure 3 (not shown), disposed along its length with oblique side flanks adapted to penetrate into the material of the superposed strips. The teeth are heated with the blocks and maintained at a selected temperature to insure at least partial penetration of strip materials and the heat sealing thereof along wide oblique flank areas. The block is mounted on guide rods 30, 32 so that it may be moved upwardly and through the slot into pressing engagement with the labels and against the bar 16. The heat is confined to the block 18 which is located below the table support so that it does not overheat the working surface. The block 18 may be moved into an actuation position in which it is pressed against the strips and against the bar 16 and held in pressing engagement a predetermined length of time which may be varied by a timer setting. Timing and heating are controlled in accordance with the type of material which is employed and the length of time which is necessary to effect the proper heat sealing of the two strips. <IMAGE>

Title: Cleaning of chemically treated articles
Inventor: SMITH PETER JOHN
IPC: C25D21/08
Filed: 1982-08-10
Abstract: As the final step of a chemical treatment operation, a treated article is rinsed with a rinse liquor to remove the chemical treatment liquid. The rinse liquor and said liquid are immiscible and are separately collectable; this permits recovery of valuable chemical treatment materials and re-use of cleaning liquids. A chlorinated hydrocarbon (low- volatility or high-volatility) can be used, preferably supplemented by a surfactant. An ultrasonic transducer may be used (particularly where the treated article is rinsed by being immersed in a bath) to assist in the removal of the chemical treatment liquid from the article, said transducer being submerged in said bath. The rinse liquor is preferably heated to its boiling point and the method is carried into effect in apparatus which includes a cooling device which condenses the vapour phase of the liquor and which promotes drying of the cleaned article.
Patent GB-2105622-A (GB)
Title: A power feed tool
Inventor: DUDDEN CHRISTOPHER JOHN
IPC: B23B47/18
Filed: 1982-08-12
Abstract: The tool has a threaded spindle (14) and lead nut (13). A first motor (12) drives the spindle and a second motor (11) drives the nut but at a slower rotational speed than the spindle so that the spindle will feed forwards relative to the nut. The motors are preferably induction motors or hydraulic motors, but at least the second motor should be of a type which cannot be over-run. The rotational speed of the spindle reduces when it is loaded by a machining operation, but the rotational speed of the nut remains constant. This will result in a lower speed differential between the lead screw and nut and the feed rate of the spindle will be set by the power of the first motor and the torque required to carry out a machining operation. Prior to a machining operation the spindle is rapidly advanced by energising only the first motor and when a machining operation has been completed the spindle is rapidly retracted by stopping the first motor whilst the second motor remains energised. <IMAGE>

Patent GB-2122779-A (GB)
Title: Access control of data transmission network
Inventor: EING HUBERT
IPC: G06F13/374
Filed: 1983-03-30
Abstract: A system for controlling access to a data bus. After a communication unit has completed transmission of a message block, the communication unit transmits a synchronization signal over the bus. Each of the communication units of the network which has a message block for transmission responds to that synchronization signal by applying to the data bus the logical ones of the address of the associated data station, or of a virtual address resulting from an algorithm performed on that station address, the logical ones being applied in sequence during respective bit intervals. During bit intervals of the logical zeros of the station address, or of the virtual address, the communication unit monitors the bus. If during such monitoring the communication unit detects a logical one on the data bus, the communication unit terminates transmission of its logical ones and awaits the next synchronization signal. Thus, the communication unit of the highest station address, or virtual address, obtains control of the bus and only one communication unit transmits a message block at any one time, assuring there is no interference or collision of message blocks. On initialization of the system, if a communication unit monitors the data bus for a preset time without receipt of any transmission, the communication unit first transmits a logical one to the data bus and then transmits the logical ones of its station address to gain control of the bus, by the above procedure.
