Title: Improved method of producing new di-substituted amides
IPC: C07C233/12
Filed: 1950-06-29
Abstract: Amides of the general formula <FORM:0683435/IV (b)/1> (wherein Y represents hydrogen or a nitro group, R1, R2 and R3 represent alkyl groups, and n is 1 or 2) are manufactured by heating the corresponding acid or mixing the chloride thereof with a dialkylamine, the free hydroxy group being, if desired, protected by esterification and the protecting group subsequently removed by saponification.  The yield may be increased by the addition of substances which bind water and hydrogen halide, and working up can be facilitated by the addition of inert diluents.  In examples: (1) acetylsyringic acid chloride is allowed to stand with diethylamine in benzene, the acetyl group being subsequently removed by saponification; (2) vanillic acid is refluxed with diethylamine in xylene in the presence of phosphorus pentoxide and glass powder; (3) carbethoxyvanillic acid chloride is refluxed with dimethylamine hydrochloride in benzene, and the product is saponified by shaking with dilute caustic soda; (4) 5-nitrovanillic acid is acetylated with acetic anhydride in ether, the product is heated with thionyl chloride, and the resulting acid chloride is reacted with diethylamine in benzene, the acetyl group being finally removed by saponification. Specification 403,892 is referred to.

Title: Process for the preparation of organodichloroboranes
Inventor: MCCUSKER PATRICK ALOYSIUS
IPC: C07F5/02
Filed: 1957-05-22
Abstract: Organodichloroboranes of the formula RB Cl2 are prepared by reacting a trimeric organoboron oxide (boroxole) of the formula (RBO)3 with boron trichloride, R being an unsubstituted or inorganic substituted saturated aliphatic, carbocyclic or aromatic hydrocarbon radical containing from 1 to 8 carbon atoms. The reaction is preferably effected by heating in the absence of air to a temperature sufficient to vapourize the product, e.g. 50 DEG  to 150 DEG C., and distilling the latter from the reaction mixture. Also, the gaseous boron trichloride may be passed through the liquid organoboron oxide. Examples are given in which R is ethyl, n-propyl, iso-propyl, sec-butyl, isobutyl, t-butyl, n-amyl, n-hexyl, cyclohexyl, phenyl and p-tolyl.  The use of organoboron oxides in which R is methyl, ethylphenyl, benzyl, o-chlorophenyl and 2,4-dichlorophenyl is also mentioned.  The organodichloroboranes may be reacted with suitable Grignard reagents to produce mixed trialkylboranes or with esters containing a free hydroxyl group, e.g. methyl ricinoleate, in the presence of caustic soda to produce the corresponding organoboronic acid esters for use as lubricating oil additives.

Title: Profile gaugins system
IPC: G01N23/16
Filed: 1974-04-16
Abstract: 1464764 Thickness deviation profile measurement WESTON INSTRUMENTS Inc 16 April 1974 [13 April 1973] 16513/74 Heading G1A In a thickness or thickness deviation profile measuring apparatus of a moving web 10 comprising a device 14 for measuring the web's velocity and 1 as source and detector units 18 and 22, one unit 22 being reciprocated across the web (see arrow 27) the other unit 18, being substantially central of the web. The detector output signals are sampled by an analogue-to-digital converters 32, 33. The output pulse width of the converters 32, 33 are proportional to the amplitude of the analogue input signal. A delay device 45 is connected to the speed measuring device 14 so that sample pulses from each detector are separated in time by an amount controlled by the web's velocity, and the samples therefore correspond to substantially the same portion of the web. The beginning of each sampling cycle is initiated by the output of a monostable multi-vibrator 48 controlled from a control logic circuit 52 such that once the first A/D converter 33 produces an output pulse on line 35 it sets a bi-stable circuit 49 and starts to charge up the capacitor 50 of a differential amplifier 44. The bi-stable circuit 49 is reset by the output of the delay device, 45 (after a delay proportional to the web's velocity) which starts the second A/D converter 32 whose output is also fed as shown to the amplifier 44 and which will tend to discharge capacitor 50. The net result is that the capacitor eventually achieves a value porportional to any variation in thickness of the two parts of the transverse portion of the web being investigated. The output of the amplifier 44 is connected through a switch 53 (controlled by circuit 52 along with a switch 51 which automatically ensures the discharging of a capacitor 50 at the end of each measurement cycle) to a differential amplifier 54. The differential amplifier 54 is connected to form a sample-and-hold circuit whose output is fed via a summing resistor 55 to the input of an operational amplifer 56, supplying the profile signal output terminal 58, and which is also fed via a summing resistor 64 with the output from a further sample-and-hold circuit 62, which by means of a bi-stable switch 65 samples the amplifier 44's output everytime the mid point of the web is passed. Thus the second sample-and-hold circuit 62 provides a correction signal (if any, since at this stage the signals from the two detectors should be equal since they have both looked at the same portion of the web). The description includes an explanation with waveform diagrams of the precise nature and shape of the pulses as they are processed through the circuit.
