Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1951-01-16
Abstract: 684,531. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Jan. 16, 1951 [Jan. 16, 1950], No. 1208/51. Class 40 (iv). In an arrangement in which subscribers' line wires are connected over high resistances r1, r2 to different potentials, the change of potential on the b wire when a call is made fires the corresponding one of a set of discharge tubes GR which are connected over a common resistance r4 to battery, and the change of potential at the junction-point fires a tube G and thereby energizes a group relay R which extends the b wires to a marker M. Line finders S operate under the control of the marker M, and when feed battery is connected to the calling line the tube GR is shunted out and the subscriber receives dialling tone. Another set of tubes GL are connected between the band c wires, and in the event of a busy condition a negative impulse on the c wire fires the corresponding tube and allows busy tone to pass from a transformer T. Similar action occurs if no dialling impulses are received, and the glowing of the tube GL indicates the defective line. The pairs of tubes GR, GL may be combined in the same envelopes.

Title: Register Detecting Arrangement for Multi-Colour Rotary Printing Presses
IPC: B41F13/02
Filed: 1968-01-10
Abstract: 1,190,851. Printing-apparatus. SIEMENS A.G. 10 Jan.. 1968 [10 Jan., 1967], No. 1506/68. Heading B6C. [Also in Division G3] Apparatus for detecting register on a printed web in a multi-colour rotary web-printing press comprises a scanner 6 rigidly coupled to a printing cylinder 7 and adapted to produce a preliminary signal which defines the space 4 between adjacent printed areas 5 on the web and also a main or reference signal, and a device 2 for optically scanning register marks 1 in the space 4, said device including a light source pulseoperated in synchronism with the preliminary signal from the scanner 6 so that intervals of maximum light intensity occur wholly within intervals in which the space 4 travels through the scanning region of the device 2. Correction signals are derived from the register marks to control the printing register. The pulse (A), Fig. 2 (not shown), caused by the detection of the marks 1 by a photo-electric cell in the device 2 is compared with the ascending line of the pulse (H) which comprises the reference signal produced by the scanner 6. The electrical signals are processed in a control system. The light source is advantageously a semi-conductor element such as a gallium arsenide diode or a gallium phosphide diode. The apparatus is designed so that the period of switching operation of the source is short compared with the smallest time difference which can be detected between the reference signal and the register mark signal. The reference signal may be produced alternatively by a mark printed by a preceding unit. A high power light flash causing a stroboscopic effect may be emitted by the source and used to detect by eye whether the register mark is in the optically effective region of the scanner at the moment of the light flash. If a deviation is detected it is counteracted.

Patent GB-1025942-A (GB)
Title: Analytical method and apparatus
IPC: G01N31/12
Filed: 1963-01-14
Abstract: A method of determining the amount in a solid test sample, of an element capable of forming a volatile oxide, e.g. C or S in a steel sample, comprises reacting particles of the test sample in a heated reaction zone (10) with oxygen, completely withdrawing a stream of oxygen and the volatile oxide and monitoring changes in thermal conductivity of said stream (measured by thermistor 20) at constant flow rate.  The above numerals refer to the Figure (not shown) in which an oxygen inlet conduit 11 is connected to the furnace 10, having a pressure regulating valve 12 giving constant oxygen pressure in the furnace, regardless of furnace oxygen requirements.  The volatile oxides formed may be passed through a filter 16, and thence to purifying towers in which one or more of the volatile impurities is removed.  A three-way valve 14 enables the gas to be passed to atmosphere, or, via capillary tube 15 reducing the pressure to atmospheric, to an oxidizing tower 18, containing, e.g. heated catalytic cupric oxide, to oxidise the volatile oxide to its highest form.  A heat exchanger 19 brings the gas stream to the temperature at which thermistor 20 has been previously calibrated with oxygen alone, and the signal from the thermistor is passed to an integrating recorder 21, which enables the signals to be read as a direct percentage of the element in the gas stream and as the total element of interest in the sample.  The C and S contents of a steel may be determined together by first monitoring a stream containing both oxides, then passing the stream through an SO2 absorber and a second monitoring stage.  The first monitor gives total C + S and the second gives C content.
