Title: Arrangement for transferring data from a punched card or magnetic card to a data processing installation or vice versa
IPC: G06F3/08
Filed: 1964-05-29
Abstract: 1,059,153. Digital calculators. K. ZUSE, [trading as ZUSE KOMM. GES.]. May 29, 1964 [June 1, 1963], No. 22372/64. Heading G4A. A record card is divided into fields comprising at least two columns each, the fields either containing information which is not processable such as customer's name or address, or processable information such as balance or credit amounts. The information from the card is entered in a buffer store 1. A mask register 7 has as many stages as there are columns on the card (in this case 80), and each stage is loaded with information to enable a data processing installation DVA to distinguish between processable and non-processable information and also to detect changes of concept during transfer of the information. Register 7 is preferably loaded so that a stage contains a 0 if the corresponding character on the card is part of a processable field, and a 1 if the corresponding character is not processable. The system operates as follows. In transferring the information from a card to DVA the contents of buffer store 1 are read out column by column in synchronism with shift to the right of register 7, conversion to excess 3 code taking place at 2. The main store of DVA comprises for example 27 word stores (this being the number of fields), each word store comprising ten 8-bit cells plus a sign " cell. A circuit 8 detects whether a field being entered is processable or not processable and causes an appropriate indication to be stored in the " sign " cell of the word register to which the field is being transferred. When a concept boundary is detected by circuit 8, any unused cells in the word register are filled with filler digits, and the next word register is selected for the next field. Since only 4 bits are required for a decimal digit, four bits of each cell are filled with a zero digit when transferring non- processable numerical information, all 8 bits being required for alphabetic data. Transfer of information from the main store of DVA to buffer store 1 prior to punching or magnetizing a record card is similar, mask register 7 causing filler digits to be ignored. If only one type of card is being used, mask 7 may be permanently loaded. Where several different card formats are in use however, the first two columns of each card may be allocated to control characters which indicate the type of format on the card. DVA is programmed to examine these control characters and to insert the appropriate masking digits in register 7. which in this case only requires 78 stages.

Title: A method of producing diphenic acid by oxidation of phenanthrene with peracetic acid
IPC: C07C51/31
Filed: 1959-06-30
Abstract: Diphenic acid is prepared by gradually introducing an aqueous solution of hydrogen peroxide into a solution of phenanthrene and acetic acid in an inert volatile aromatic solvent which forms an azeotropic mixture with water, and removing the water from the mixture during the addition of hydrogen peroxide, continuously by distillation.  The diphenic acid is separated by neutralisation of the mixture followed by acidification, or preferably by cooling the mixture, removing the crystallised diphenic acid and reusing the separated solution, after addition of phenanthrene, for further oxidation.  Specified aromatic solvents are benzene, toluene, xylene and nitrobenzene.  The processes are described in examples.
Patent GB-942944-A (GB)
Title: Dehydrogenation of aliphatic hydrocarbons and catalyst therefor
IPC: B01J23/26
Filed: 1960-06-27
Abstract: A cataylst for dehydrogenating C3-5 hydrocarbons is prepared by dehydrating an alumina hydrate composition containing at least 60%, preferably 70-100%, beta alumina trihydrate, adjusting the surface area of the dehydrated alumina to 100-200 m.2/g. by heating with steam, depositing chromia to provide a catalyst comprising 10-25% Cr2O3 and which is steamtreated.  The catalyst preferably contains combined alkali metal, e.g. 0,2-1,2% Na2O.  In examples, the initial alumina hydrate is mulled with nitric acid and the steam is diluted with 80% hydrogen or air for the final treatment.

Title: Apparatus for ocular refractometry
IPC: A61B3/103
Filed: 1965-05-27
Abstract: 1,099,317. Eye-testing apparatus. STATE OF ISRAEL and N. Ben-Tovim. May 27, 1965, No.22617/65. Heading G2J. Eye-testing apparatus having means for projecting a beam of light into a patient's eye P' comprises a cylindrical lens 206 positioned between the patient's eye P' and the examiner's eye O' so as to produce an astigmatic beam from the light reflected from the eye P', this latter beam being observed by the examiner as a streak of light perpendicular to the axis of the lens 206. Light from a source 115 is directed on to a semitransparent mirror 101 which reflects the light into the eye P'. The mirror 101 may be rotatable about an axis parallel to the focal line of the lens 206 so that the beam of light may be moved across the patient's eye. For an ametropic eye such movement will cause the light streak viewed by the examiner to move along its length, whereas for an emmetropic eye the streak will disappear suddenly in an indistinguishable direction. A phoropter 133 carrying correcting lenses is positioned in front of the eye P', the lenses being selected to effectively produce an emmetropic eye. An "auxiliary eye" comprising a lens 95 and a screen 96 housed in a tube 148 is illuminated by light transmitted through the mirror 101 and is viewed simultaneously with the eye P' by the examiner. This "auxiliary eye", having no astigmatic aberration, provides a reference streak which indicates any such aberration in the eye P'. The lens 206 is mounted for rotation about the optical axis between the mirror 101 and the eyepiece 214 of the apparatus in order to find the orientations of the meridians of the eye P', these being indicated on an arcuate scale 250 by a pointer 254. In an alternative embodiment, the light streak is made to move across the retina of the eye O' by means of an apertured diaphragm 219 between the lens 206 and the eye-piece 214, the diaphragm being rotated manually.

Title: An autodialer
Inventor: TAKAHASHI TETSUJI
IPC: H04M1/276
Filed: 1963-06-06
Abstract: 995,702. Substation apparatus. NIPPON COMMUNICATIONS INDUSTRIAL CO. Ltd. Nov. 26, 1963 [June 6, 1963], No. 22641/63. Heading H4K. An autodialler comprises a matrix of magnetic cores having an X wire threading a horizontal row for each digital value, a Y wire threading a vertical row for each digital position and an AA-wire threading selected cores one in each column indicative of a subscriber's number. The horizontals are scanned cyclically at the digital pulsing rate and the verticals are scanned in succession each vertical being scanned for a duration equal to a horizontal cycle. The pulsing is arranged to start at the beginning of each cycle and to terminate when the horizontal scan reaches a core in the presently scanned column and which also contains an AA wire. This may be achieved by exciting any two of the X, Y and AA circuits and observing coincidence in the third. Thus the cores may have a rectangular hysteresis loop and only change state when two of the windings are energized (either by D.C. or A.C.) the change of state being observed in the third winding. Alternatively two windings may be fed with A.C. of different frequencies and the third winding to detect the simultaneous presence of these frequencies. In the embodiment shown depression of an appropriate button AS connects up a corresponding AA wire and simultaneously starts a motor which steps SX, SY and opens impulsing contacts P synchronously with the stepping of SX. The latter in its first position sets trigger B to operate relay A which removes a shunt across contacts P to allow the impulses to go to line. When SX reaches position 2 (with SY on position 1) coincidence is detected by wire AA to reset trigger B so that A releases to terminate the impulsing. Subsequent digits are sent similarly.

Title: Improvements in or relating to compression ignition engine fuel systems
IPC: F02M13/06
Filed: 1956-07-24
Abstract: 841,261. Fuel injection systems; regulating. CALIFORNIA RESEARCH CORPORATION. July 24, 1956, No. 22870/56. Classes 7(3) and 7(6). One of two fuels 13, 33, or a mixture thereof is selected by a valve device 5 and circulated through a header 23 from which the fuel injection pumps 27 and injectors 28 are fed. Light fuel 13, filtered at 16, is fed by a pump 11 to a passage 7 and heavy fuel 32 is fed from a tank 58 by a pump 61 through a heater 54 to a passage 6. At starting a valve 12, operated according to engine conditions such as load or speed, closes the passage 6 and opens passage 7 so that light fuel alone passes through pipe 3 to a pump 10 which circulates the fuel through a closed circuit 26 including the header 23 and a back pressure valve 25. As the engine load or speed increases the valve 12, which may be actuated by pressurised air in pipe 8 the pressure of which is varied by a speed responsive governor, progressively opens passage 6 and closes passage 7 so that a mixture of the fuels passes to the pump 10. Circulation of the fuel through circuit 26 prevents the deposition of solid matter from the heavy fuel. The pumps 61 and 11 are provided with by-pass valves 71 and 30 which open at predetermined pressures. The heater 54 is an electric heater the circuit of which is controlled by a thermostat 74 which prevents the fuel temperature exceeding 265‹F. The tank 58 is supplied by a pump 36 from a tank 33, the fuel being preheated in a heater 39 and passed through a filter 42 and a device 45 which includes a centrifugal separator and a means for reducing the size of the fuel particles. Excess fuel is returned from tank 58 through an overflow 53 to the tank 33. A manually operated valve 1 may be set to by-pass the mixing device 5 through a pipe 4 so that the engine operates solely on light fuel. In the modified mixing device 5 of Fig. 4 the valve 12 only controls the heavy fuel inlet 6, the light fuel inlet 7 being permanently open. Alternatively the device 5 may be arranged so that a rapid changeover from light to heavy fuel is made at a predetermined load or speed.
