Title: Delay line
IPC: H04N5/95
Filed: 1964-10-05
Abstract: 1,036,374. Delay equalization; television. FERNSEH G.m.b.H. Oct. 5, 1964 [Oct. 5, 1963], No. 40467/64. Headings H4F and H4R. The delay of a video signal is adjusted relatively to a reference signal by passing the video signal through a series of delay line units A0, A1, A2, Fig. 1, each unit comprising a pair of delay lines having different delay times, the particular delay line in use being selected by the setting of associated switches D0, E0, D1, E1 &c., which are adjusted by a digital control signal derived from an analogue representation of the delay difference between the video and reference signals. The control circuit is shown in Fig. 2 in which an error detector F compares the video and reference signals to provide an analogue error signal which is applied to the analogue digital converter G which produces an output on 1 to k of the 1 to n leads where k is representative of the analogue value. This digital signal is applied to code converter H which produces a signal on one lead (e.g. k) of the 1 to n output leads, which via a matrix J selects the appropriate switching arrangement to reduce the error signal to zero. Since each digital output of the code converter corresponds to a particular error voltage range, and these ranges must not overlap the logic circuit K is provided so that should no digital output be detected at the matrix, due to the error signal being in the region between two ranges, the logic circuit raises the analogue control signal until a digital output appears.

Abstract: 926,939. Detecting radio-activity. OSTERREICHISCHE STUDIENGESELLSCHAFT FUR ATOMENERGIE G.m.b.H. Dec. 2, 1960 [Dec. 5, 1959], No. 41459/60. Class 40 (3). It has been found that the ratio of the α activity to the # activity of a gaseous medium, e.g. air, due to artificially produced radioactivity, e.g. due to a defective reactor, differs from the corresponding constant ratio of α and # activity due to the natural radioactivity of the medium and the present invention utilises this to determine the artificial radioactivity of the medium. As shown the gas is drawn by a pump 13 through a filter 1 which collects the radioactive particles and after a predetermined period, e.g. half an hour, the portion of the filter which has been exposed to the gas is moved rapidly to a position between a pair of detectors 2, 3 producing electrical pulse outputs at rates proportional to the # and α activity respectively, the output pulses being applied through respective amplifiers 5 to rate meters 6 producing corresponding D.C. voltages whose amplitudes are recorded at 7 and 9 as a transverse displacement of a mark on a record strip, Figs. 2 and 4 (not shown), which is moved with the filter 1, the ratio of the D.C. voltages as determined by a comparator 4 being recorded at 8 in a similar manner on another record strip, Fig. 3 (not shown). The above operation is repeated a number of times so that the records indicate changes in the radioactivity; alternatively the filter 1 may be moved continuously.

Abstract: 1,096,030. Forced breathing apparatus. O. H. DRAGER, [trading as DRAGERWERK HEINR. & BERNH, DRAGER], Sept. 19, 1966 [Sept. 18, 1965], No. 41811/66. Heading A5T. Artificial respiration apparatus comprises chambers 7, 8 in which alternate positive and negative pressures are produced, inhalation and exhalation bags 9, 18 connected by ducts 10, 17 with the patient and each disposed in a chamber, non- return valve 24 between the exhalation bag 18 and the ambient atmosphere and a second valve 19 in the exaltation duct 17 which opens only when negative pressure is produced in the chamber 8 surrounding the exhalation bag 18 so that exhalation air can flow into the exhalation bag. The ducts 10, 17 are connected to the patient by non-return valves 11, 16 respectively and hoses 12, 15. The chambers are connected to a device for producing positive and negative pressures by joints 3, negative pressure being produced in each of the chambers simultaneously so that air is drawn from the ambient atmosphere into the inhalation bag 9 through a non-return valve 14 as exhalation air flows into the exhalation bag 18 through the valve 19. The occurrence of positive pressure in the chambers causes air to flow from the inhalation bag to the patient and from the exhalation bag through the valve 24 to the ambient atmosphere. In an alternative construction arranged for closed circuit operation, the inhalation and exhalation ducts are connected by a valve (27, Fig. 2) which has less resistance to opening on the application of negative pressure than the valve 19, so that initially exhalation air fills the inhalation bag 9, surplus exhalation air passing to the exhalation bag via the valve 19. The circuit includes a carbon dioxide absorber (30) and an anaesthetic gas supply pipe (31) in the inhalation duct upstream of the inhalation valve 11.

Heading A4P. A walking stick, umbrella or baton, for use by pedestrians in conditions of bad visibility, comprises a section of tubular translucent or transparent plastics material containing one or more electric filaments, the article also containing electric batteries and a flasher unit connected so as to cause the filaments to emit an intermittent flashing light. The plastic tube 12 is attached by screw-threaded extensions to sections of vulcanised fibre tube 11 and 13, the latter section carrying a force-fitted wooden ferrule 14. An electric light bulb 15 is supported within the plastic tube by the lower end of a flasher unit 17 of conventional type, which is a force fit in the plastic tube. Two brass strips 20 and 21, of arcuate cross-section are brazed to the flasher contacts 18 and 19 and extend to the top of the fibre tube 11, where they are secured to the handle 10, the strip 20 being connected through a switch 27 to a spring- urged contact 24 which bears upon one end of the batteries 32 accommodated between the brass strips. The strip 21 has a contact tongue 31 extending between the other end of the batteries and a wooden dowel 33. Closure of the switch 27 completes the circuit and causes the bulb to emit a flashing light. The handle 10 is a push fit in the upper end of the fibre tube 11, and may be withdrawn, together with the brass strips and the batteries, to renew the latter. In an alternative construction the batteries are contained within an inner vulcanised fibre tube, the connections being made with wires in place of the brass strips. The translucent plastic tube may be incorporated in the ferrule of an umbrella or in a hand-held baton (e.g. for used by children), or alternatively the tube, flasher unit and batteries may comprise a separate unit attached to a stick or umbrella.
