Abstract: 818,575. Photographic shutters. KODAK Ltd. June 5, 1957 [June 8, 1956], No. 17872/57. Class 98(1) A photographic shutter includes a rotatably oscillatable member, an impact member adapted to be releasably held in a latched position, and a pivoted lever connected to one or more shutter blades; the parts being so arranged that upon release of the impact member, by means of a shutter trigger, it strikes the oscillatable members which-at the commencement of the consenquent rotation in the directionactuates the pivoted lever to open the shutter blades which are then held in the open position until the oscillatable membertowards the end of the reverse oscillation - allows the lever to return the blades to the closed position. As shown, the shutter includes blades 4 and 5 hinged at 6 and 7 and each having a slot engaged by the pin 10 on a pivoted lever 33 rotation of which causes the blades to rotate and open the aperture 3. Depression of the trigger 40 causes flexure of the spring 16 and tension to build up therein until the end 18 of the trigger engages a flange 26 of the holding latch 22b which then releases the impact member 12 to rotate rapidly clockwise under spring 16. The arm 14 of the member 12 strikes the shoulder 27 of the oscillatable member 28 to cause it to rotate anticlockwise; the end 32 of the lever 33 is forced out of the notch 31 causing the shutter leaves to open and remain open until the member 28 has completed an oscillation and returned to its original position under the action of the spring 29s, thereupon the arm 14 rides over a ramp 27 on the member 28 to its rest position, and the member 33 returns to its initial position under the action of the spring 35 to close the shutter blades.

Filed: 1959-05-29
Abstract: <PICT:0948814/C1/1> In the production of titanium dioxide by passing titanium tetrachloride and oxygen into a fluidized bed of inert particles, accretion of titanium dioxide on the material of the bed is diminished by introducing into the bed chlorinating and reducing agents.  Preferably, gaseous chlorine and carbon monoxide or carbon, or a compound agent having chlorinating and reducing functions such as phosgene, is fed to the bed.  The reducing agent if solid is preferably suspended in the chlorinating agent and both are preferably fed in close proximity to the titanium tetrachloride feed; alternatively, the solid may be suspended in the tetrachloride feed. In addition to the agents above referred to, a metal such as aluminium may be introduced into the bed preferably suspended in a gas.  Additionally a small amount of a chloride of another metal or a metalloid such as silicon may be mixed with the titanium tetrachloride. The titanium tetrachloride/oxygen ratio may be from 1 to 0.2 to 1 to 3.  As shown in the drawing, a fluidized bed of zircon is formed above a porous ceramic plate 5 through which fluidizing air is admitted from pipe 15; titanium tetrachloride is fed at 250 DEG C. through pipe 14 and a ceramic disc 11, whilst carbon monoxide and chlorine are introduced into the middle of the bed through a pipe 21. The amount of chlorinating and reducing (or combined) agent introduced may be from 10 to 300 mole per cent based on the tetrachloride feed.  Specifications 761,770, 919,019 and 948,813 are referred to.

IPC: G06F7/50
Filed: 1970-04-20
Abstract: 1293442 Data processing INTERNATIONAL BUSINESS MACHINES CORP 20 April 1970 [2 May 1969] 18709/70 Addition to 1218407 Heading G4A An electronic data processing system, wherein logic and arithmetic functions are performed by table-look-up operations on stored function tables, comprises at least one read-only function store containing function tables, at least one work store arranged in operation to store operands, and a microprogramme store arranged in operation to emit microinstructions each including an operation code, each function and microprogramme store comprising a read-only store and having a respective decoder arranged to decode a part of the operation code particular to the store. In the CPU, address, data and control buses interconnect two work stores, a main store, the microprogramme read-only store and a branch read-only store for it, and readonly function stores (for binary addition, shift, ORing, EXCL-ORing, and inversion). Arrays of read-only function stores feeding each other are disclosed. The branch store evaluates (b#c)#a, and uses it as part of the next microinstruction address, the rest coming from the current microinstruction. Here a, b, c are 4-bits each, and come from the current microinstruction, the address bus and the data bus respectively. Address, data and control buses interconnect the CPU with I/O controllers each of which has two work stores, arithmetic and logic arrangements and a function control, similarly to the CPU. Requests for access to the buses from the CPU and I/O controllers, if concurrent, are resolved using a priority table in a readonly store. The CPU and I/O controllers communicate with each other via respective reserved areas in main store. Error correction Hamming code generators (using tables in read-only stores) are provided for the inputs and outputs of the CPU work stores. Multiplication is by examining the multiplier bits in turn using a mask, a 1 bit causing the multiplicand to be added into a result field, and in either case the multiplicand and multiplier then being shifted one place left and right respectively.
