Title: A device for connecting a sailmast to a sailboard
IPC: B63B15/02
Filed: 1978-11-13
Abstract: A device for connecting a sailmast 1 to a sailboard 2 comprises a mast- connecting universal joint 3, which is connected at one end to the mast and is permanently fixed thereto or can be only arbitrarily separated therefrom and is connected at its other end to a supporting member 4, which when the device is in position for use is received at least in part by a recess in the upper surface of the sailboard so as to be positively connected thereto. To provide for an overload coupling, preferably in combination with an easily operable device for shifting the mast in the longitudinal direction of the sailboard, the supporting member is constantly biased by a spring 6 so that the positive connection can be eliminated only in that the spring force is overcome. <IMAGE>
Patent GB-2012084-A (GB)
Title: Queuing data
IPC: G06F9/46
Filed: 1978-12-22
Abstract: One or more queue structures in a data processing system includes a threaded list of priority frames which are tied to a so-called lock or control frame with synchronization for multiple processing units. Each priority frame includes a priority number, a pointer to the next frame in the list, and data. The lock frame includes a lock, and head and tail pointers pointing to the priority frames at the head and tail of the list. The priority frames are arranged in priority order, highest priority at the head of the list. A new priority frame may be added to the list by a queue- on-head (QOH) or queue-on-tail (QOT) instruction which causes the new priority frame to be added before or after, respectively, the existing priority frames of the same priority. A dequeue-by-address (DQA) instruction causes the priority frame at a specific address to be dequeued, whereas a dequeue-from-head (DQH) instruction causes the first priority frame of a specified priority (or lower priority if no priority frame of the specified priority exists) to be dequeued. <IMAGE>
Patent GB-2017219-A (GB)
Title: Gas Turbine Plant
IPC: F02C3/20
Filed: 1979-02-28
Abstract: The plant comprises a combustion chamber 3, which may be a fluidised bed combustion chamber, an air compressor 1 having its outlet side connected to the chamber 3 by a pipe 5, and a pipe 6 for conveying combustion products from the chamber 3 to the inlet side of a gas turbine 2. For the purpose of stopping the turbine rapidly, in the event of a sudden loss of load or damage to the plant, valves 7 and 8 are provided in the pipes 5 and 6, respectively, and a third valve 9 is provided between the pipes 5 and 6. Normally the valves 7, 8 are open and the valve 9 shut, but when it is required to stop the turbine, the valve 9 is opened and the valves 7, 8 are closed. This has the effect of by- passing the combustion chamber 3 so that cool air flows from the compressor 1 directly to the turbine 2. The load of the compressor rapidly slows down the turbine. <IMAGE>
