Patent GB-2088035-A (GB)
Title: Finned-tube heat exchanger
IPC: F28F1/32
Filed: 1981-10-20
Abstract: A plurality of tubes 32 through which a fluid to be cooled is passed extend through aligned openings 31 in a stack of heat transfer fins 30 and are bonded to projections 33 which bound edge portions of each opening 31. Edges of the projections 33 remote from each fin 30 engage the next adjacent fin in the stack, thereby spacing adjacent fins apart from one another. The remote edges are prevented from entering the respective opening 31 in the adjacent fin 30 by lateral protrusions 34 which also serve to strengthen the projections against buckling as the tubes 32 are inserted through the openings 31 during assembly. In alternative embodiments, entry of the projections into the adjacent openings is prevented by bent-over ears at the ends of said remote edges, and by making the projections trapezoidal in shape so that said remote edges extend beyond the ends of the adjacent opening. A method of forming the fins is also disclosed. <IMAGE>

Title: A method of communicating with a computer, and a user-operated input device for a computer
Inventor: FINE BRIAN
IPC: G06F3/16
Filed: 1983-11-03
Abstract: The items on a menu 12 of computer inputs 14 available for selection by the user are indicated by the input device one by one by a continuously repeated series of corresponding outputs indicated on a speech generation unit or a VDU, for example, controlled by a control unit. In the Figure the computer is controlling the state of a machine. The available instructions are "ON" and "OFF". When the user says "ON" or "OFF" into a microphone in chorus with the device, as at times 16 and 18, the corresponding input is applied to the computer, which turns the machine on or off. If the user says a word other than one of the words in the menu, no input is applied to the computer. At time 20 the user says "STOP", but the computer does not switch the machine off. This discrimination is effected by an analyser analysing the output of the microphone and providing signals to the control unit. <IMAGE>
