Title: Apparatus for comparing hydraeric pressure signals and detecting disparity therebetween
IPC: F15B18/00
Filed: 1966-11-16
Abstract: 1,133,939. Fluid-pressure servomotor systems. BELL AEROSPACE CORP. Nov.16, 1966 [Dec.1, 1965], No.51272/66. Heading G3P. An apparatus for comparing fluid-pressure signals and detecting disparity between them comprises a comparator unit 18, having identical sections 40, 60, and 80, a lockout unit having identical valves 120, 121 and 122 and a delay unit, having identical valves 110, 111 and 112. Output signals from each of three servovalve mechanisms (11, 12 and 13 Fig.1) are fed into the comparator at 17, 19, and 21, analyzed, and appropriate output signals are produced at 22, 25, and 27 these signals then acting on three switches (23, 26, and 28 Fig.1) which control the pressure supply to the servovalves. An abnormal signal from any one such valve results in a changed signal being fed to the appropriate switch, as a result of which the valve is cut out. Immediately after switching on, the state of the various components would be as shown in the drawing, pressure to the switch means being supplied, through the valves 110, 111 and 112, by means of a connection between P 1  and each of the A, B and C. After a predetermined period of time each of the delay valves is caused, due to fluid entering chambers 114 through control valve 118, to move to the right thus breaking the connections P 1  -A, P 1  -B and P 1  -C and making new connections between the ducts 107, 108 and 109 and exhaust R 1 . This state is stable and maintained until comparator conditions change. If, for instance, signal 17 becomes greater than 19 and 21 then spool valves in sections 40 and 80 move to the right and left respectively, thus connecting duct 104 to 109 i.e. to exhaust. This results in a fall in pressure in 104 and the consequent action of the changed signal 22 on switch 23 cuts off servovalve producing the abnormal signal 17. The cut-out is made permanent, irrespective of subsequent changes in signal 17, by means of lockout valve 120. With the fall in pressure in 104, valve 127 is caused, by means of the pressure supplies P 1  and P 2  at 132 and 135 respectively, to move to the right so connecting duct 104 to exhaust via duct 123. The sensitivity of the apparatus is governed solely by the crosssectional area of the valves, the size of the springs &c., and may therefore be designed to compare any signals. Similarly the delay action may be pre-set by adjustment of valves 118.

Title: Data-processing systems
IPC: G06F11/10
Filed: 1974-11-28
Abstract: 1484169 Data processing system COMPAGNIE INTERNATIONALE POUR LINFORMATIQUE 28 Nov 1974 [4 Dec 1973] 51592/74 Heading G4A In a data processing system of the kind in which sequences of instructions, e.g. microinstructions, are read from a store, e.g. an R.O.M., by a logic unit arranged to derive the address of the first instruction of a sequence from a stored OP-code and thereafter to derive the addresses of the remaining instructions of the sequence, each instruction except certain common instructions which may appear in more than one of the sequences, having a part characteristic of the sequence to which it belongs, the correctness of the addressing of the store is checked by comparing a cede derived from the OP-code with a code characteristic of the sequence to which the instruction belongs and derived from each instruction word read from the store, the comparison being inhibited whenever one of said certain common instructions is read from the store. As described an OP-ccde is loaded in register CO via input Exe and logic LC, while a word indicative of the number of micro-instruction words to be readfrom store MK to execute the OP-code is loaded in register R. The logic LC derives the address of the first micro-instruction from the OP-code CO, and via LA addresses the store. The instructions contain an address part A which is used by LA to derive the address of the next instruction, the contents of R being decremented as each instruction is read out. The OP-code is applied to code converted TCO which derives a code C of fewer bits than the OP-code and characteristic of the operation to be performed. The part K of the instruction is applied to the logic LA and to a code converter TCV which derives a code v of the same number of bits as C and characteristic of the operation performed by the sequence read out. Alternatively the code v can be read directly from part of the current instruction. The codes C and v are compared at COMP, disagreement indicating that an incorrect instruction has been read out due to an addressing error. Certain instructions which may be read out produce (or contain) a special code v, e.g. all 0's or all l's, indicating that the instruction is not one of a specific sequence but is not necessarily incorrect, e.g. it is part of a subroutine which may be called by several sequences. This special code disables the comparator to prevent an error indication. The comparator COMP need not compare bit for bit but may match arbitrarily selected codes. Several different codes K may produce the same code v where there is no risk of confusion.
