Abstract: 1362679 Radiation therapy control VARIAN ASSOCIATES 12 Nov 1971 [27 Nov 1970] 24345/73 Divided out of 1362678 Heading G4H  In a computer controlled radiation therapy machine where the computer contains a patient's treatment plan comprising radiation doses to be given for prescribed positions for the machine, the plan is displayed to an operator and updated by the amount of radiation given in any step of the treatment to give a cumulative total of radiation given to the patient. The plan comprises a number of machine positions at which radiation is to be given for any one treatment session, each position being defined by the positions of a couch and gantry containing the radiation source, and there being prescribed doses for each position defined by the radiation attenuation to be used and blocks to be used which blank off those parts of the patient not needing irradiation. The computer indicates to the operator which step of the treatment is to be performed next. The total radiation given for each position is accumulated as well as a grand total. The treatment plan may be altered by an operator, any new set of positions or radiation doses being compared against acceptable limits. Patients' treatment plans are recorded on individual cassette tapes which are read into the computer store before the treatment begins and the up-dated plan being rerecorded on the cassette at the end of treatment. The automatic positioning of the parts of the machine form the subject matter of claims of Specification 1,362,678. Communication between the digital computer and analog sensors sensing the radiation and position of the machine parts is via an interface unit containing A/D and D/A converters.

Abstract: 389,119. Wired-wireless signalling. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London.-(Assignees of Ganz, A. G.; 109, Can'tello Street, Union City, New Jersey, U.S.A.) Sept. 10, 1931, No. 25389. Convention date, Oct. 18, 1930. [Classes 40 (iii) and 40 (v).] Relates to a two-way repeating system for carrier currents and comprises the use of both balanced and unbalanced filters, the necessary transformers being so located that crossmodulation. products arising from them are not passed on. Lower-frequency carrier current passes line 1 to line 2 through filter 9, amplifier 16 and filter 20, while higher-frequency current passes from line 2 to line 1 via filter 17, amplifier 16 and filter 5. To economize material, the inner portions 7, 11, 25, 26 of the filters are unbalanced, and in order that the line-balances may not be upset, shielded transformers 8, 12, 24, 21 have to be inserted between these and the balanced outer portions 6, 10, 23, 22. Although the filter coils are air-cored, the transformers are iron-cored ; the out-going lowfrequency signals therefore generate modulation products in transformer 21, but these are choked by the balanced filter 23 before they reach transformer 24. Similarly, if lowfrequency modulation products arise in transformer 8 from the interaction of two outgoing high frequencies, they are prevented by the balanced section 6 from entering the lowfrequency path at 10.
