Patent GB-1523005-A (GB)
Title: Data processing apparatus
IPC: G06F7/00
Filed: 1976-05-05
Abstract: 1523005 Arithmetic units; memory protection INTERNATIONAL BUSINESS MACHINES CORP 5 May 1976 [18 June 1975] 18383/76 Heading G4A An ALU 20 has a first part 20a operating on a pair of operands to produce a result S0-S3 which is fed immediately to one input of a second part 20b of the ALU to produce a second and different result S4-S7. The ALU may be divisible by control signals 21 into two equal 4-byte halves as disclosed in Specification 1,522,045. The ALU has inputs from A and B registers 26, 27 and its two halves operate on the high order bytes 0-3 and low order bytes 4-7 of these inputs respectively. The B input is via true/complement gates 33 acivated by a control bus 35 as required for addition/subtraction. The gates 33 and the ALU are of the flow through type and do not rely on timing signals for signal propagation so that the sum S0-S3 can be made to appear at the input of ALU half 20b delayed only by the circuit delays inherent in gates 33. This gives faster operation when performing memory address foundary protection checks. Memory protection.-A user supplies an identification code together with an identifier for the storage area for which an access request is being made. After checking the identification code using a protection table in main storage 13, the processor sets the start address SA and upper boundary UB in a local register 30 and honours the access request. A storage access instruction loaded into the instruction register 32 includes a storage area code and access length code (number of bytes) for the request. The OP code of the instruction causes control 16 (microprogrammed or hard-wired) to divide ALU into the two halves 20a, 20b. The high order half 20a is controlled to add the start address SA of the requested area with the access length from register 32 and the low order half 20b is controlled to subtract the sum S0-S3 from the upper boundary UB by complementary addition. If the access request would violate the upper boundary an extent error signal is generated by the carry output CY from ALU half 20b and control 16 initiates an error handling routine. If the upper boundary is not exceeded, the sum output 50-53 is passed from the Z register 34 to the high order field 30a of the local register via a shifter 24 and destination register 25 so that the start address is replaced by an updated address to be used by the processor in handling the next access request in a similar manner.

Title: Apparatus for the stabilisation of ships
IPC: B63B39/06
Filed: 1939-06-26
Abstract: 589,643. Electric automatic control systems. BELL, J., and WRIGHT, C. S. June 26, 1939, Nos, 18520 and 25709. [Class 38 (iv)] [Also in Group XXXIII] Apparatus for stabilizing ships against roll pitch or yaw is provided with arrangements whereby the control impulse for the removal arid reversal of a stabilizing torque is initiated prior to'the end of the swing by a time interval which approximates to the time lag inherent in the stabilizing system employed, e.g. gyroscopic systems, anti-roll tanks or hydraulic jet apparatus. A control arm 3 secured to the control gyro 2 depends between main plungers 5 on bell-crank levers 6, spring tied to a pivoted ratchet-toothed quadrant 8 to which is attached a second spring-loaded plunger 11. The arm oscillating under precessing of the gyro 2 when the ship rolls closes contacts 4, 41, whereby through the energizing of electromagnets 10, the pawls 9 are caused to engage with the teeth of the quadrant 8. The pressure exercised by the spring plungers 11, 5 on the arm 3 causes the re-centring of the arm 3 prior to the reduction of the roll velocity to zero by a time interval independent of the angle of swing. In a hydraulic arrangement, Fig. 2, the arm 3 operates a jack which controls the supply of pressure fluid to bellows 13, 15 connected by a one-way valve 16, the exhaust valve 18 closing the bellows 15 being controlled by an electromagnet 10 associated with the contacts 4, 41. In a further modification, the bellows are replaced by cylinder and piston combinations. Accidental impulse owing to the inertia of the gyro causing it to overshoot when being recentred may be eliminated by the employment of electromagnets of the slugged type which retain their magnetism for a short time after the energizing current has been cut off.

Title: Improvements relating to filters and purifiers employed for conditioning air, for example for respiration, by freeing it from poisonous gases and other injurious or undesired substances
IPC: B01D53/26
Filed: 1936-07-07
Abstract: The method described in the parent Specification, of indicating the exhaust of respiratory and air-conditioning filters by the passage of current between electrodes in the filter on moistening of hygroscopic material between the electrodes, is improved by the provision of a hygroscopic material which, on passage of current through it when moistened, evolves a substance acting upon the respiratory mucous membranes and/or reacts with another substance to give a visual indication.  Suitable materials are alkaline iodides or bromides, especially sodium iodide, the iodine from which on electroylsis by the current may give warning by smell or a visual indication by reaction upon starch.  The warning given may be additional to or may replace the electric signal of the parent Specification.  Mixtures of two hygroscopic materials, chemically inert until moistened, may be employed, the components causing primary actuation of the electric and the sensory indications respectively, but by reaction generating the sensory indicating substance more readily than a single material. A suitable mixture comprises sodium iodide and magnesium chloride. The electrodes may be constructed and arranged as described in Specification 450,825, the sensory signal in this case ceasing when the electrodes are brought into contact by spring pressure.  The Specification as open to inspection under Sect. 91 refers broadly to the production of an indicating substance acting upon one of the senses.  This subject-matter appears in the Specification as accepted only in the form set forth above.

Abstract: 256,609. British Thomson-Houston Co., Ltd., (Assignees of White, W. C.). Aug. 10, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Automatic circuit-breakers; electromagnetic switches.-The armatures of electromagnetic or magnetic switches are composed of a material having a marked temperature coefficient of permeability such as an alloy of 70 per cent nickel and 30 per cent copper, and are heated directly or indirectly by currents so as to fall away from their electromagnets or magnets when heated. Fig. 1 shows one form in which the armature 12 when moved into engagement with the electromagnet 10 by hand closes a circuit at 14 through itself and the electromagnet, and is held attracted by the electromagnet till it becomes sufficiently heated to lose its permeability when it falls away by gravity, breaking the circuit again at 14. In a modification, the coil 11 is constantly energized and attracts the armature which then closes a circuit which indirectly causes a heating current to flow through the armature. In another modification, Fig. 3, the coil 11 after attracting the armature 12 serves also to heat it. Fig. 4 shows an interrupter, in which the armature 12 is first attracted to the permanent magnet 10, thereby closing a circuit through itself, and is then heated and falls away again, the process being repeated indefinitely.
