Title: Process for the preparation of amino-pyridyl-azoquinolines and products obtained thereby
IPC: C09B41/00
Filed: 1932-07-11
Abstract: 2<1> : 6<1> - Diaminopyridyl - 8 - azoquinolines are manufactured by diazotizing 8-aminoquinoline or its substitution products and coupling the diazotized product with 2 : 6 - diaminopyridine, both steps taking place in the presence of an excess of acid amounting to more than one equivalent, e.g. 10--30 equivalents.  Suitable substitution products of 8-aminoquinoline are those containing a halogen atom or an alkoxy group in the 6-position and those containing an alkoxy group in the 6-position and a halogen atom in another position.  Examples describe the use as diazo components of: (1) 8-aminoquinoline; (2) 6-methoxy-8-aminoquinoline; (3) 6-ethoxy-8-aminoquinoline; (4) 6-chloro-8-aminoquinoline.  The reaction in each case is performed in the presence of excess of hydrochloric acid, the products being obtained in the form of their hydrochlorides from which the free bases are liberated by ammonia. The Provisional Specification comprises the use, as coupling components, of aminopyridines in general.

Title: Improvements in or relating to the manufacture of flat material
IPC: B24B49/00
Filed: 1963-05-21
Abstract: 1,072,551. Inspecting surfaces photoelectrically. PILKINGTON BROS. Ltd. J.R. BEATTIE and A. G. OGILVIE. April 28, 1964 [May 21, 1963], No.20273/63. Heading G1A. Surface pits on flat glass or metal are detected by shining an elongated beam of light on to the surface, forming an image of the light reflected from the surface, scanning the image to produce an electrical signal indicative of pit size and analyzing the signal to give an indication of the size distribution of pits. A line filament lamp 4 illuminates a slit 9 which is imaged on the surface of a glass sheet 1. Light reflected from the sheet is imaged on a rotating disc 14 in which there is one or more pinholes 16 which effectively scan across the sheet. Light passing through pinhole 16 falls on a photo-multiplier 17. The photomultiplier output is fed to a single- or multichannel pulse height analyzer so that the size distribution of pits may be displayed. Each channel is as shown in Fig. 4. The method may be used for detecting pits in milled or plated metals or ground glass which may be aluminized to increase reflectivity. Mechanical scanning may be replaced by a cathode ray tube with a single line or raster scan. The relationship between the number of lines and the material speed is taken account of in the counters. A sample cut from a larger piece may be set up vertically on a traversing table and inspected by a horizontal light beam.

Title: Gaseous discharge panel
Inventor: SCHMERSAL LARRY J
IPC: G09G3/28
Filed: 1972-05-02
Abstract: 1399131 Matrix displays OWENS-ILLINOIS Inc 2 May 1972 [3 May 1971] 20316/72 Heading G5C A method of operating a gas discharge panel having crossed conductor arrays insulated from a non-cellular gas space comprises applying unidirectional pulse trains of opposite polarity to the conductors of each array, modulating the width of a pulse to a selected conductor of one array, and a parameter of a pulse train to a selected conductor of the other array to manipulate the stored charge at the site located by the selected conductors. To erase a discharge a shortened pulse is applied to one conductor V 5  and the sustain pulses to the other selected conductor Hs are delayed by half a cycle. To ensure that non-selected cells are not erased the same delayed sustain pulses and a shortened pulse are applied to the remaining horizontal conductors H NS  and sustain pulses moved forward by half a cycle are applied to all vertical conductors V S  and V NS . A write operation is obtained by extending the length of a sustain pulse. The sites are conditioned by pulse lengthened further up to 15 Ás. Write and erasure of all cells is described. A small voltage #V may be added to reduce half select effects and may be D.C. or a pulsed supply from a transformer. The sustain voltages are applied via diode selector matrices described in Specification 1,364,686. The sustain pulse width is less than 10 Ás preferably between 0À8 and 5 Ás to reduce the ion-current and lessen wall damage due to ion impact. Damage is further reduced by applying a pulse of polarity opposite to the sustain pulse to decelerate the ions (Fig. 5A).

Patent GB-1432763-A (GB)
Title: Compressors expanders and noise reduction systems
IPC: H03H11/04
Filed: 1972-05-02
Abstract: 1432763 Companders DOLBY LABORATORIES Inc 30 April 1973 [2 May 1972] 20406/72 Heading H4R A compressor, Fig. 5a, or an expander, Fig. 5b, comprises a linear main path LN and respectively a negative feedforward orapositive feedback further path including a circuit 19 having characteristics, Fig. 4, such that below a threshold T the gain falls with reducing signal level whereas above the threshold the gain is constant. The circuit is termed a "conveyer" and is the complement of a limiter normally employed in the further paths of types 1 and 2 compressors and expanders and in this configuration provides a type 3 device. The Specification also discloses a device in which the conveyer is in a negative feedback loop or a positive feedforward loop to constitute respectively a type 4 compressor or expander, the subject of divided Specification 1,432,764. Both types operate in compressor mode to subtract little or no signal from the main path at low signal level but progressively move as the signal level rises to the threshold and thereafter. A type 3 compressor (Fig. 12, not shown) has a resistive (R4) main path and a further path constituted by the emitter circuit of transistor (T1) acting as a conveyer with a further transistor (T2) and an FET (F2) whose conductivity is increased with increased signal level fed to the base of T1 by a filter (28). At low signal levels within the filter passband, the impedance of (F2) is high and the emitter current of (T1) is determined largely by (T2) resulting in little gain. As the signal level rises the impedance of (F2) falls resulting in increased gain until (F2) is fully conductive after which the gain is constant at (R5/R7). Smoothing of the control signal may be in two stages of short and long time constant coupled by a diode-resistor combination ensuring fast attack and reduction in the longer time constant for large, abrupt changes. Diodes D5, D6 prevent overshoot. The further path may include multiple filters, conveyers and associated control circuits in tandem (Fig. 13, not shown) to provide non- interfering action on different frequency bands. Also, the filter in the further path may automatically broaden its passband as the signal level in the stop bands increases by locating the conveyer FET (F3, Fig. 14, not shown) across the resistor (R8) of a tuned bpf (R8, L1, C3). Low level signals in the stop bands are therefore blocked but high level signals are passed so that frequencies outside the narrow passband undergo compressor action.
