Abstract: 1,236,485. Dyeing or bleaching textile spools. INSTITUT FUR TECHNISCHE NACHFORSCHUNGEN, ANSTALT. 2 June, 1968, No. 18653/68. Heading D1L. A plurality of supports each carrying a plurality of textile spools is transported in series successively into a treatment vat and a hot air drying vat, the steps of the preparation of the treatment liquid, the treatment, the drying and spool transporting being effected automatically by means of a conventional punchtape unit. Control of the treatment parameters e.g. temperature may also be effected automatically. The treatment liquid may be heated at a rate of at least 10‹C/min, passed through each spool in less than 1.5 sec and recycled through a circuit comprising the treatment vat and an expansion chamber once per minute. As shown, spools 1 are treated in a vat 8 by passing treatment liquid through them under the action of a pump 35, said liquid being heated by a coil 37 in the vat. The liquid is prepared in a calibrated reservoir 9 and circulated through the vat 8 and an expansion chamber 10 by a pump 11; additional liquid prepared in an auxiliary vat 12 is added to the treatment liquid in the expansion chamber from a dosage tank 13. The expansion chamber also regulates the evacuation of liquid from the vat 8 via the discharge 50. The spools are dried with compressed hot air in an autoclave vat 15. The liquid levels in the expansion chamber, calibrated reservoir and auxiliary vat are controlled by constant level float devices. The spools and their supports are transferred to and from the treatment vat and autoclave vat on a transport device 4 comprising two rolling paths 27 and a cross beam 26. The auxiliary vat 12 and dosage tank 13 may be replaced by a graduated flask 103 (Figs. 2 and 6). Two calibrated reservoirs 9, 9' (Figs. 5 and 6) may be used alternately, one providing treatment liquid while the other prepares liquid and vice versa. Similarly two auxiliary vats 12, 12' (Figs. 5 and 7) may be used alternately. A pre-treatment which may be a boiling vat may be arranged upstream from the treatment unit 5 and a post-treatment unit may be arranged between the treatment unit 5 and the drying unit 7.

Filed: 1972-04-21
Abstract: 1377566 Electron beam apparatus LICENTIA PATENT-VERWALTUNGS GmbH 21 April 1972 [24 April 1971] 18682/72 Heading H1D An electron multiplier comprises a semiconductor 4, Fig. 1, which is mechanically reinforced and divided into discrete regions on its input surface and provided with an emissive coating 6 on its output surface. A disc of semiconductor material such as Zn doped GaAs or Si doped with B with a charge carrier concentration greater than 10<SP>19</SP>/cm<SP>3</SP> may be selectively etched to leave reinforcing areas 5 and to form the blind holes 3 terminating in the electron multiplying areas 4 which should be at least as thick as the penetration depth of the incident electrons but no thicker than the diffusion -length of the generated electrons with thermal energy. The coating 6 may be a few atoms thick of electro-positive metal such as caesium. The surface 4 may be more strongly doped to form a P + layer. In a modification, Fig. 3 (not shown), the surface 5 is covered with insulation, e.g. SiO 2  if the semi-conductor is silicon, which is in turn covered by a conductive layer of aluminium or gold which is maintained at a negative potential relative to the semi-conductor; alternatively the conductive layer may be omitted, the insulating layer then being charged negatively by the incident electrons to create a field which diverts electrons away from areas 5 and towards the multiplying areas 4. In a further modification, Fig. 2 (not shown), the reinforcing grid is of different material from the semi-conductor. A thick semi-conductor plate may be joined to a grid-like carrier plate of nickel or conductive glass by gluing, sintering, soldering, or pressing, and the semi-conductor plate is then reduced to the required thickness by etching. Alternatively a semi-conductor coating is formed by epitaxial deposition on a flat support plate in which apertures are subsequently formed. The support plate may be another semi-conductor with similar crystal structure or a metal such as molybdenum. The multiplier may be used in an image intensifier (Fig. 4, not shown) or in an oscillograph tube (Fig. 5, not shown).

The makeready for compensating for inaccuracies of the punching tools can be effected either on the roller 17 or on the inner side of one of two plates replacing, and supported similarly to, the plate 36.
Patent GB-458511-A (GB)
Title: Improvements in the manufacture and production of amines and amides
Filed: 1935-07-01
Abstract: Amines and amides of the formula RN(CH3)2, in which R is any hydrocarbon or heterocyclic radicle or substitution product thereof, or any carboxylic acid radicle, are obtained by reacting compounds of the formula RX, where X is halogen linked directly to carbon, with an excess of dimethylamine under pressure with the practical exclusion of water and under such conditions that the dimethylamine hydrohalide formed as a by-product is permitted to settle out as a layer or precipitate at a temperature above 50 DEG  C.  The layer or precipitate of dimethylamine hydrohalide is then separated from the solution of the desired product in excess of dimethylamine, either directly or after the mixture has been cooled.  The process is based on the observation that the hydrohalides of dimethylamine are practically insoluble in liquid anhydrous dimethylamine at temperatures above 50 DEG  C. If the reaction is effected at above 100 DEG  C., the hydrohalide is deposited as an oily layer; this may be separated immediately, or alternatively the mixture may be cooled (to below 50 DEG  C. if desired) to convert the oily layer into a crystalline precipitate, which is then filtered; a crystalline precipitate is also obtained if a chlorine compound is used in the reaction and the latter is effected at 50--100 DEG  C.  Examples are given in which dimethylamine is reacted, under conditions as defined above, with (1) o-chloronitrobenzene, (2) benzyl chloride, (3) ethylene bromide, (4) butyl chloride, (5) ethylene chloride, (6) stearic acid chloride, (7) cyclohexyl chloride, and (8) 2-chloropyridine. Other halogen compounds which may be treated are ethyl chloride, bromide and iodide, dodecyl chloride, monochlorodecahydronaphthalenes, other chloronitrobenzenes, 2-chloroquinoline, acetyl chloride and benzoyl chloride.

Title: Manufacture of glyoxalidinearylmethylols
IPC: C07D233/22
Filed: 1933-07-04
Abstract: m -Glyoxalidine-aryl-methylols are prepared by reacting an imino-ether of mandelic acid containing in the nucleus at least one free or etherified hydroxyl group with ethylene diamine or an N-substituted hydrocarbon derivative thereof.  When a free hydroxyl group is present in the products it may subsequently be etherified, whilst if aralkyl ethers are used as starting materials the aralkyl groups may be split off.  The products, which have the formula <FORM:0422057/IV/1> where R represents a phenyl radicle containing at least one free or etherified hydroxyl group and X stands for hydrogen or a hydrocarbon radicle, are useful therapeutically.  Examples are given of the interaction of (1) m-benzyloxymandelic acid imino - ethyl ether or 3 : 4-dibenzyloxymandelic acid imino-ethyl ether with ethylene diamine, followed by removal of the benzyl group or groups by treatment with hydrogen in the presence of palladium; (2) 3 : 4-methylenedioxymandelic acid imino-ethyl ether with ethylene diamine; the first component may be replaced by m-hydroxymandelic acid imino-ethyl ether or 3 : 5-dimethoxymandelic acid imino-ethyl ether; (3) p-methoxymandelic acid imino-ethyl ether with methylethylene diamine.  Further examples describe (4) the methylation of m-hydroxyphenylglyoxalidyl-carbinol with dimethyl sulphate, and (5) the reduction of m-benzyloxyphenylglyoxalidyl - carbinol with stannous chloride to eliminate the benzyl group.  The mandelic acid imino-ethers are prepared by reacting the appropriate substituted benzaldehydes, e.g. 3 : 4-ethylenedioxybenzaldehyde, with hydrocyanic acid and treating the resulting cyanhydrins with alcohol and hydrochloric acid.  3 : 4-Ethylenedioxybenzaldehyde is obtained by treating protocatechuic aldehyde with ethylene bromide in the presence of alkali.

Filed: 1976-05-10
Abstract: 1518010 Automatic control of air/fuel mixture in IC engines NISSAN MOTOR CO Ltd 10 May 1976 [12 May 1975] 19089/76 Heading G3R A fuel control system employs an exhaust gas sensor to provide a main control signal and means to detect parameters indicating a vehicle starting condition to provide a modifying signal which is combined with the main control signal to enrich the air/fuel mixture when the vehicle starts from rest. As shown the exhaust gas sensor output is compared with a reference level in comparator 16 and then passes through a proportional stage 19 and integral stage 20 in parallel to summing amplifier 24 which provides a fuel control signal to the metering system. Vehicle starting is sensed by throttle, gear lever and clutch switches 26, 27, 28 which when all operated pass a signal through AND gate 29 to differentiator 31 which provides a peak signal to the amplifier 24 so that it produces a maximum fuel signal for a short period. In a first modification, Fig. 1 (not shown), a resistor/diode network is connected in series with the proportional and integral amplifiers and have their impedance values charged by transistors which are made conductive when vehicle starting is detected thus increasing the fuel supply signal. In a further modification, Fig. 3 (not shown), the output of amplifier 24 is passed to a level detector which provides a signal when the air/fuel ratio is low and this signal passes, together with the vehicle starting signal,through an AND gate and differentiator to provide a signal to a further amplifier which outputs an increased fuel command signal.
