Title: Iminoisoindolinone pigments and process for their manufacture
IPC: C08K5/34
Filed: 1973-12-03
Abstract: 1411018 Colouring polymers CIBA-GEIGY AG 3 Dec 1973 [5 Dec 1972] 55953/73 Headings C3P and C3R [Also in Division C4] Iminoisoindolinone pigments of the general formula wherein R 1 , R 2  and Y are H, halogen or alkyl or alkoxy containing 1-4 carbon atoms and each X is halogen are used in the mass coloration of cellulose ethers, and esters, e.g. ethylcellulose, acetylcellulose and nitrocellulose, polyamides, polyurethanes, polyesters, natural or synthetic resins, e.g. aminoplasts especially urea-formaldehyde and melamine formaldehyde resins, alkyd resins, phenoplasts, polycarbonates, polyolefines, e.g. polystyrene, p.v.c., polyethylene, polypropylene, p.a.c., polyacrylic acid esters and thermoplastic or curable acrylic resins, rubber casein, silicone and silicone resins, optionally in the form of spinning solutions, lacquers, or printing inks.

Patent GB-1326233-A (GB)
Title: Control systems
IPC: G05B19/27
Filed: 1970-11-25
Abstract: 1326233 Control apparatus LITTON INDUSTRIES Inc 25 Nov 1970 [26 Nov 1969] 55961/70 Heading G4H A signal representing the measured dimension of a workpiece W (Fig. 2) being shaped by a tool (13, Fig. 1, not shown) is compared with a signal representing the required dimension, by complementing the latter and adding the complemented signal to the measured signal in an adder, the output from which controls first relative advance of the tool and workpiece until the workpiece is of the required dimension and then relative retraction. As described, a multi-digit number representing the required dimension of a workpiece being ground by a wheel (13, Fig. 1) is read either from a card 57 or from setting switches 62 into complementing circuits 65 (one for each digit) connected to respective adders 64, 74 ... in comparators 56, 55.... The adders receive their second inputs from an encoder 51 receiving the analogue output of a caliper 50 measuring the workpiece dimension. Initially a rapid feed piston (15) is actuated to drive a feed-screw (14) and hence, via gearing (17), a shaft (18) carried by the support for the grinding-wheel. At the end of the rapid feed movement a further piston (23) is operated to move the shaft (18) via gearing (27, 28, 29 and 19, 20). When all but the least significant digits of the actual and required dimensions are identical incremental feed is initiated. At this time AND gate 73 associated with the second least significant digit is enabled by the "1" output of adder 74 and the "match" output of the preceding character 64 to prime AND gates 66, 67 in comparator 56. Consequently when the actual dimension is larger than the required dimension the resulting carry signal from adder 64 passes gate 67 to actuate a piston (37, Fig. 2, not shown) to move the vertical shaft (18) and consequently the wheel support and wheel. When all the bits of the least significant digit of the actual required dimension are equal gate 66 is enabled resulting in retraction of the rapid feed piston (15) and grinding feed piston (23). It also causes a fixed number of retractions of the incremental piston (39) to cause reverse rotation of the feed-screw (14) to retract the wheel support. The incremental speed may be initiated when digits other than the least significant are unequal by appropriate modification of the circuitry of Fig. 2.

Title: Method and apparatus for testing jitter
IPC: H03K5/156
Filed: 1967-12-19
Abstract: 1,201,278. Testing jitter. INTERNATIONAL BUSINESS MACHINES CORP. Dec.19, 1967 [Dec.30, 1966], No.57738/67. Heading G1U. The specification describes a system for testing "jitter" produced in pulse trains passing through a device such as a magneto-strictive delay line, jitter being defined as the variation in pulse delay through the device which is dependent upon the pulse sequence in a serial pattern of pulses. Selected serial patterns of pulses 2 synchronized with a train constant frequency and width pulses derived from a clock 1 are applied to the line, while a given phase difference between these input pulses and the clock pulses is introduced by the variable delay line 3. The output pulse train from the line 4 under test is passed through the standardizer 6 to produce constant width output and to the AND gate 5. The pulses from the variable delay are also standardized at 7 and passed to the gate 5. When a coincidence is detected a latch 8 is set and a lamp 9 lights to indicate coincidence. The delay 3 is adjusted to determine the smallest and largest valves where a coincidence is obtained. By subtracting a correction factor representing the widths of the standardized pulses from 6 and 7 from the delay time difference so obtained the extent of jitter on the pattern pulses as all possible patterns are developed from the generator 2 is ascertained. A more complex embodiment in which the delay line tap is adjusted automatically after each generator of the overall pattern is described Fig.3 (not shown). In this embodiment also, provision is made for negative going (NRZ) pulses emitted from the test line 4, and for recording the overall delay time during which coincidences are obtained, by counting each time a given delay results in a coincidence.

Title: Control circuit for electronic flash appliances
IPC: G03B15/05
Filed: 1973-12-14
Abstract: 1411650 Electronic flash control FRANKE AND HEIDECKE GmbH 14 Dec 1973 [3 Feb 1973] 57963/73 Heading G2A In a control circuit for electronic flash, in which the output from an integrating device charges the control grid of a switching element, a pulse is delivered to interrupt the flash discharge when the potential on this control grid exceeds the cathode potential by the ignition voltage of the said element. As shown, when the appropriate contacts are closed, the flash tube 3 is ignited, and the light reflected from the subject is received by a phototransistor 9. A voltage corresponding to the time integral of the current from the phototransistor is generated on a capacitor 10, and this determines the grid potential of a thyristor 13. When this potential exceeds the cathode potential by the ignition voltage, the thyristor arcs through. The thyristor is in the discharge circuit of a capacitor 14 in series with the primary winding of an ignition transformer 15, and generates a pulse which blocks a thyristor 4 in series with the flash tube 3, hence interrupting the flash. This arrangement is of advantage in avoiding over-exposure, when the distance between camera and subject is short, caused by the time which elapses between the emission of the interrupting pulse and the actual extinguishing of the flash.

Filed: 1969-12-05
Abstract: 1286682 Separation of gas mixtures FLUOR CORP and AMOCO PRODUCTION CO 5 Dec 1969 [5 Dec 1968] 59639/69 Heading F4P In a process for obtaining liquid ethane and higher hydrocarbon products free of carbon dioxide and methane, the undesirable gases are removed in one step and without the separation of solid carbon dioxide. Compressed feed gas is partially condensed by heat exchange at 2 and passed into a separator 4; liquid phase is passed directly to a mid-point 11 of a separating column 9 and the gaseous phase is expanded through a turbine 7 before being passed to the top 9a of the column 9. The pressure and temperature of the column prevents separation of solid CO 2 , and CO 2  and methane gas are removed in line 13 and used to cool the feed stream. A portion of the condensate in column 9 is used in re-boiler 12, whilst the remainder is passed via pump 18 to a second separating column 20. Ethane/propane gas is removed as overhead from column 20, condensed by heat exchange in reboiler 12, and passed via accumulator 28 and pump 30 either to product store or to reflux in column 20. Butane and higher fractions are removed as bottom liquid from column 20. The turbine 7 also drives a compressor 16 for the methane and carbon dioxide gas in line 13, and may drive a compressor 16a for the feed gas.

Title: Processes and apparatuses for recovering clean water and solids from aqueous solids
IPC: B01D1/26
Filed: 1979-10-15
Abstract: Aqueous solids are mixed with a low viscosity, relatively volatile, water- immiscible light fluidizing oil to obtain a mixture which will remain fluid and pumpable after removal of substantially its entire water content. The mixture of solids, water and fluidizing oil is subjected to a dehydration step by heat evaporation whereby substantially all of the water and at least part of the light oil are evaporated and subsequently recovered. The light fluidizing oil is then largely separated from the solids. Those solids carrying residual light fluidizing oil are then brought into direct contact with steam, referred to herein as "blowing steam". The presence of the blowing steam reduces the boiling point of the water- immiscible light fluidizing oil to effect its more efficient removal from the solids. Effluent blowing steam and light oil vapor removed from the solids may be used to supply heat to the overall process. <IMAGE>
