Patent GB-1490422-A (GB)
Title: Integrated semiconductor device for the line scanning of an image
IPC: H04N5/369
Filed: 1975-01-28
Abstract: 1490422 Television systems ITT INDUSTRIES Inc 28 Jan 1975 [30 Jan 1974] 3703/75 Heading H4F An integrated semi-conductor assembly for scanning an image includes a row of seriallyconnected inverting photo-sensitive transistors which, in use, are exposed to the brightness profile of a line of the image. A pulse is propagated along the row, the speed of travel of the pulse varying according to the luminance received by the portion of the row through which the pulse is currently travelling. Gates are connected along the row to generate a series of pulses, each of which has a duration dependent upon the luminance on the corresponding portion of the row. Each gate G1, G2, . . . , Fig. 1, may be an OR gate which has its inputs, e.g. E11, E12, Fig. 2, connected to the collectors of two transistors of the row, the inputs being spaced by an odd number of transistors so that in an initial state, in which a switch S applies earth to the first transistor of the row, each gate provides a high output to line L. When switch S is reversed, in response to a line frequency pulse, for example, a pulse is propagated along the row, the pulse being inverted by each transistor. When it reaches E11 the output of gate G1 goes low causing a low potential on line L. It remains low until the pulse reaches E12, and then remains high until it reaches input E21 of the next gate G2, and so on. The pulse duration and pulse spacing of the signal on line L therefore corresponds to the propagation time, and hence on the luminance, at the corresponding portion of the row. The pulse width modulated signal may be converted to an amplitude varying signal for display. The constant current sources 10, I1 ... may be varied in accordance with line frequency pulses and the signal on line L to control the mean transit time of the pulse along the row. The output of the last transistor in the row may be connected to the input of the first to provide repeated scanning.

Title: Improvements in or relating to automatic telecommunication exchange equipment
Inventor: BRAY FREDERICK HARRY
IPC: H04Q3/00
Filed: 1954-10-05
Abstract: 794,816. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Sept. 30, 1955 [Oct. 5, 1954], No. 3938/56. Divided out of 794,812. Class 40 (4). In an automatic exchange a ring- trip circuit is common to a group of lines and the reply of a called party causes the circuit to disconnect the ringing current supply from all the lines of the group, the circuit then reconnecting ringing current to any other called line(s) of the group after a delay during which the path over which it was applied to the line which has answered is broken in the line circuit of that line. The invention is described as applied to the system described and claimed in Specification 794,812. A wanted line is marked by positive potential applied from the called line marker which is extended via the lower winding of RR and the talking wires to the anodes of the tubes (not shown) forming the connector for that line. The cathodes of the connector tubes are scanned by negative pulses and the pair of tubes interconnecting the wanted line with the first free final link (not shown) fire to the combination of pulse and marking. Relay RR operates and connects ringing current from the ring-trip circuit to the positive lead to ring a grounded bell at the called substation. On the reply of the called party, relay F pulls up to the loop and locks under control of the normally operated FA. Operation F disconnects the ringing current supply from the lines of the group, releases the differential relays RR of all called lines of the group by increasing the current in their upper windings, and opens the circuit of FA. The release of RR connects the line wires to relay L in each case, and the L relay of the answered line operates in the loop and short-circuits the lower winding of relay RR of that line to prevent its re-operation on the release of F. The release of FA brings down F whereupon the RR relays of all other lines of the group which are being called re-operate, and ringing current is re-applied to those lines.

Title: Improvements in or relating to the production of soldered joints on circuit carrying panels
IPC: B23K3/06
Filed: 1957-02-05
Abstract: 825,297. Soldering. GENERAL MILLS Inc. Feb. 5, 1957 [Feb. 16, 1956], No. 3992/57. Class 83 (4). [Also in Group XVIII] In making soldered joints at selected locations on a circuit carrying panel, the panel is brought into contact with a masking template mounted above a solder bath for movement towards and away from the bath and having a plurality of apertures to expose the panel at the locations and the template and panel are first lowered and then after a predetermined period raised together with respect to the bath to dip the template and panel into the solder to cause the solder to rise in the apertures to temporarily contact the locations; the panel is finally removed from the template. A panel 146 having electric components 148 on the top side thereof with their connections 158 extending through the panel into contact with a printed circuit on the lower side is positioned in slots formed by rivet heads 98 and bars 94 in which the rivets are fixed, the bars forming part of an adjustable support head secured to a piston in a pneumatic cylinder 114 on a machine frame. A stainless steel template 82 having recesses 90, Fig. 8, and apertures 84 corresponding with the connections 158 on the panel is screwed to a frame 76 having lugs 78 resting on springs in guide members 64 carried on uprights 60 on the frame. A pot 11, carried by the piston of a pneumatic cylinder 14 on the frame, contains solder 12 heated by electrical elements and temperature controlled by means 58, the upper surface of the solder being in contact with the template. The level of the solder is maintained by a float 34 operating a switch 44 controlling a motor 26 for feeding solder rod from a reel 22 through a duct 30 into the solder-bath. The float device also operates an indicating pointer on a dial. In operation with flux applied to the connections 158 a switch is pressed to actuate a solenoid valve allowing air into the cylinder 114 to lower the panel 146 into contact with the template. The rivets 98 engage the recesses 90 and the template and panel are together pushed into the solder against the spring-loading provided in its support mounting. Solder rises through the holes 84 and effects soldering of the connections 158 to the printed circuit. A switch 118 operated by a stop 116 on the descending piston-rod actuates a timing device which, after a predetermined time, de-energizes the solenoid valve to effect raising of the piston to allow raising of the template and panel together and then effect the lifting of the panel from the template. The cylinder 14 is provided to allow lowering of the pot 11 before shut down, so that damage due to the machine being operated with the solder solid, is prevented.

Title: Improvements in and relating to apparatus for filling containers with liquid
IPC: B67C3/12
Filed: 1957-02-06
Abstract: 817,823. Automatic pressure control systems. MEYER LIQUID Ltd., and FRIENDSHIP, K. F. M. Feb. 5, 1958 [Feb. 6, 1957], No. 4047/57. Class 38 (4). [Also in Group XVII] In a counter pressure bottle-filling machine a column of liquid is balanced against the pressure in the filling-tank 1 and the pressure in a vessel 15 for counter-pressure fluid, and changes in level of the liquid are detected and utilized through suitable relay or transducer means to control the pressure in vessel 15. Liquid is supplied to filling-tank 1 through pipe 2 and the level is maintained constant through a device 6 as described in Specification 631,610. Air under pressure is supplied to tank 1 through pipe 13 and control 12 from a supply line 8. Counter pressure is supplied to a ring main 22 through line 21 fed from vessel 15 which is connected to line 8 through a three-way valve 17 including a vent 19. A U-tube containing a liquid such as oil has one limb 23 in communication with line 13 feeding the liquid tank 1, while the other limb 24 communicates with the pressure vessel 15. A detector 27, e.g. a photoelectric cell in conjunction with a light source or a radio-active isotope in conjunction with a Geiger-Muller rate meter or an ionization chamber, senses a rise in level of liquid in limb 24 due to a fall in counter pressure and causes operation of a relay 28 operating three-way switch 17 which opens to allow counter pressure fluid to enter through line 16. If counter pressure becomes too great the vessel 15 is vented to atmosphere. The U-tube may be replaced by a single column of liquid, the upper end of which is in communication with a diaphragm or other displaceable member subject to filling tank pressure. A balanced relay or transducer system is attached to the diaphragm to control the pressure of vessel 15. Specifications 541,200, 650,454, 790,506 and 817,824, [all in Group XVII], are referred to.

Abstract: 1375485 Reducing iron ore CENTRO SPERIMENTALE METALLURGICO SpA 28 Jan 1972 [3 Feb 1971] 4077/72 Heading C7D In the direct production of liquid carburized iron layers of carbonaceous reducing material and iron ore mixed with flux are formed against the inner wall of a cylindrical rotating reactor, the reducing material layer being adjacent the wall. Carbon monoxide produced by the reaction escapes through the ore layer and is burnt by a jet of pure or substantially pure oxygen injected into the reactor to provide part of the necessary heat. Liquid iron flows to the bottom of the reactor through the layers and is withdrawn from a central hole while the solid materials are maintained as layers by centrifugal force and friction. After a layer of ore is completely reacted it is renewed and the layer of reducing agent is simultaneously rebuilt. Further heat may be supplied by the combustion of solid, liquid or gaseous fuel, e.g. by combustion of a part of the fuel layer which remains uncovered during renewal of the layers or by combustion of additional fuel mixed in the layer of ore.
