Title: Improvements in sea-navigation radar
Inventor: ALBERTI CARLO
IPC: G01S1/02
Filed: 1965-10-25
Abstract: 1,106,230. True motion radar. SELENIAINDUSTRIE ELETTONICHE ASSOCIATE S.p.A. 25 Oct., 1965 [19 Dec., 1964], No. 45006/65. Heading H4D. The invention relates to a ship-borne radar having a P.P.I. true motion display, means for producing a marker on the display to indicate the relative motion of a target and means enabling the result of a change of the ship's course to be investigated. The P.P.I. display 6, Fig. 3, has its origon shifted by the output of a true motion computer A. This comprises a generator 1, giving a voltage indicating the ship's speed V, and feeding it to a cos/sin resolver 2, having its rotor turned in accordance with the ship's bearing a. The output at 30 thus represents V cos a, and that at 31 represents V sin a. When a ganged switch 7 is not in an OFF or PS position, the velocity components are integrated in integrators I 1  and I 2  to give at 32 and 33 the resolved distances moved by the ship along orthogonal axes. These are fed to the display 6 to produce a true display. In the plotting position PT of switch 7, the output of computer A is also fed to means 8 which controls the origon of a rotatable marker. At the start of a plotting interval, with the ship's echo C, Fig. 4, at the centre of the display and a target echo at T, manually applied signals at 81 and 82 move the origon of the marker to coincide with T. At the end of the plotting interval, true motion has caused echo C to move to C<SP>1</SP>, and echo T to move to T<SP>1</SP>. Since means 8 is fed with the output of computer A, the origon of the marker has moved to R<SP>1</SP>, with TR<SP>1</SP> = CC<SP>1</SP>. If the marker is rotated to pass through T<SP>1</SP>, it represents the relative motion of the target and the closest point of approach, may be determined by tangenting the marker to a circle, centre C<SP>1</SP> as shown. A possible collision situation is illustrated. During the plotting interval, a D.C. voltage is fed to an integrator I 3  in a future motion computer B, which produce a rising output representing time after the commencement of the plotting interval. This is fed to a potentiometer 4 which has a wiper set in accordance with the new ship's speed to be investigated. The reduced output from the wiper is fed to a sine/cosine resolver 5 set in accordance with the bearing of the new ship's speed. The outputs of the resolver are fed to switch points PP. Thus at the end of the plotting interval when the above procedure has shown a collision possibility, switch 7 is switched to the PP position. The marker origon now moves from R<SP>1</SP> to R f <SP>1</SP> and the marker R f <SP>1</SP>-T<SP>1</SP> indicates a much larger and safer miss distance C<SP>1</SP>-CP<SP>1</SP>. Alternatively the wiper at 4 can be set to the change of speed intended, resolver 5 to the change of bearing intended, and the signals applied at points PP arise from an adder 9 adding the outputs of computer A to the respective outputs of resolver 5.

Abstract: 1,200,448. Making combustible gas. IMPERIAL CHEMICAL INDUSTRIES Ltd. 3 Oct., 1967 [10 Oct., 1966], No. 45204/66. Heading C5E. A hydrocarbon feedstock of high C.V. and high hydrogen to carbon ratio is catalytically steam reformed in substantially non-oxidative conditions to give a gas containing H 2  and carbon oxides, and the gas is catalytically partially oxidized with O 2  (air) to produce a gas of lower C.V. and lower hydrogen to carbon ratio. There is sufficient hydrocarbon present in the second (partial oxidation), step to take up by reaction with steam a substantial part of the heat evolved by the partial oxidation, so that the temperature of the gas leaving the second step is less than that of the gas leaving the first (primary reforming) step. The feedstock may be natural gas or refinery gas, and may be additionally injected between the two steps, e.g. to the extent of 25 to 60% of the hydrocarbon in the second step, permitting primary reforming at temperatures of 700‹ to 850‹ C. Methanol may be injected into one or both steps, and the second step is preferably carried out at such a temperature that carbon monoxide conversion occurs, and steam may be added to this step for this purpose. Steam ratios (moles steam per carbon atom in the feed) in the range 1À3 to 5À5, preferably 2 to 4, ensure sufficient steam for reaction with hydrocarbon in the second step. Outlet gas temperatures from the second step of 600‹ to 750‹ C. are mentioned.

Abstract: 460,269. Cash registers. NATIONAL CASH REGISTER CO. July 19, 1935, No. 31983/36. Convention date, July 19, 1934. Divided out of 460,194. [Class 100 (iv)] [Also in Group XIX] Hammer-impression arrangements.--In a cash register or similar accounting-machine, the slip printing hammer makes a stroke during each operation, and a slip feeler controls the position of the hammer actuating means relatively to the hammer in such a manner that in one position the hammer stroke is ineffective whilst in another position the hammer stroke is effective. The hammer 52 and slip feeler 76 are both actuated by cams rotatable on a stud 56 and geared to a drive shaft 58. The stud is carried by an arm 57 rockable about the shaft 58 and urged towards its upper position by the hammer-spring 54. The arrangement is such that with the arms and cams in lower position, the hammer is able to make an impression, but when the cams are in upper position, the throw of the hammer is completed before the platen reaches the type. The arm 57 is lowered twice during each operation by a pitman 62 operated by a cam 65 and connected to the arm by a lost-motion device consisting of a stud 60 normally retained by a spring 66 at the upper end of a slot 61 in the pitman. While the cam is lowered for the first time, the feeler is freed and rotates clockwise to sense the slip. In the presence of a slip, the feeler is arrested in such a position that a shoulder 75 thereon abuts a shoulder 74 on the arm and holds the latter depressed when released by the cam 65. In these circumstances, printing takes place. In the absence of a slip, the shoulder 75 moves past the shoulder 74 and the arm and cams are free to rise and prevent printing. Upon the second lowering of the arm the feeler is restored to normal position.

Abstract: 1400353 1400353 Data processing systems INTERNATIONAL BUSINESS MACHINES CORP 4 Oct 1973 [6 Dec 1972] 46308/73 Heading G4A  In a system in which blocks of data are transferred between a buffer store 14 and a backing store 17 in response to an access request for data which is not in the buffer store 14, the presence of a request for the last addressable item in a block is detected and a dummy request is generated for another block so that it may be transferred from the backing store to the buffer store. The system is described in connection with I/O transfers between a channel 25 and the storage system 12. At the start of an I/O operation, channel 25 makes a control word (CW) request for a channel address word stored at a predetermined address, a request signal 68 being passed to storage system 12 via gates 72, 78, 79 and the address being passed to an address register 26 via gates 65. The addressed word is sent to channel 25 over line 23 and is loaded into a register 82, and the CW request is then terminated. Latch 87, set by the CW request enables gates 88, 83 to pass the address of the first channel command word of a channel program from register 82 to address register 26 via gates 65, and generates a dummy request 68 via gates 102, 79. The system then operates, using a directory 32 and swap logic 35, to transfer the relevant data block from backing store 17 to buffer store 14 if it is not already in buffer store 14, but access to buffer store 14 is inhibited at gate 45. Subsequently, channel 25 supplies the address of the first channel command word to address register 26 to obtain that word from buffer store 14. Each control word request results in a dummy request operation at the end of which latch 87 is reset. Data requests are handled normally except that, a request for the last word in a block is immediately followed by a dummy request for the next adjacent block, this operation being effected by a last word detection gate 94, -latch 95, gates 98, 102, 79 producing the dummy request, and a block address incrementer 96 and gates 99.
