Patent GB-862193-A (GB)
Title: Process for preparing trisubstituted s-triazines
Filed: 1958-10-07
Abstract: Tri-substituted s-triazines are prepared by trimerizing a mixture consisting of an imidate base of formula <FORM:0862193/IV (b)/1> in which R is an aliphatic or aryl radical and R1 is an alkyl group having up to 6 carbon atoms or phenyl, with an acid addition salt of the imidate base, preferably in a substantially anhydrous medium. The products are 2,4,6-tri-substituted s-triazines in which the substituents correspond to the group R of the starting materials.  R may be, for example, methyl, ethyl, propyl, hexyl, octyl, lauryl, stearyl, 4-cyanobutyl, trichlormethyl, a -bro-methyl, methoxymethyl, propoxymethoxy ethyl, allyl and other propenyl groups, phenyl, naphthyl, nitrophenyl, chlorphenyl, cyanonaphthyl or 3-anthraquinonyl.  The acids used for the formation of the acid addition salts include weak and strong inorganic and organic acids as well as substances capable of coordinating or complexing with a base. Suitable acids are, for example, hydrogen chloride, sulphuric, phosphoric, nitric, oxalic, chlorsulphonic, trifluoroacetic, acetic, lactic, citric, tartaric, benzoic and toluic acids as well as Lewis acids such as carbon dioxide, borontrifluoride, silica gel and silica-alumina gel.  The preferred temperature range for carrying out the process is 25-200 DEG  C.  The imidate salt may be formed in situ by treating the imidate with less than the stoichiometric amount of acid and the resulting mixture may be trimerized.  An imidate salt of a weak acid may be formed by treating a salt of a strong acid with an alkali salt.  In the preparation of the mixture prior to trimerization, a solvent may be used.

Abstract: 1440224 Fluid-pressure servomotor systems ROBERT BOSCH GmbH 5 July 1973 [6 July 1972] 32076/73 Heading G3P A pressure regulator for a compressed air braking system of a vehicle, connectible to normally allow compressed air from a compressor 2' to pass via port 4, filter 5', passages 6, 9, checkvalve 10 and port 11 to reservoir 3', includes an unloader valve 26 which opens to unload the compressor discharge to atmosphere when the pressure downstream of the check-valve 10 reaches a desired value. The pressure is communicated to a chamber 18 via passage 12, throttle 13, expansion chamber 16 and further throttle 17, where it causes piston 19 to raise a valve 20 and thereby communicate the pressure with a piston 24 which then opens the unloader valve 26. The throttling at 13, 17 and the expansion in chambers 16, 18 ensures that the change-over point of the regulator is not adversely affected by pressure peaks of alternative compressors having different swept volumes or by pressure fluctuations between the compressor and reservoir. The vehicle tyres may be inflated by the compressed air via adapter 8.

Title: Improvements in or relating to the application of steam and extraction of condensate from rotating steam-heated appliances
IPC: D21F5/02
Filed: 1936-11-26
Abstract: 469,712. Rotary steam-heated appliances. KINGCOME, H. A. Nov. 26, 1936, No. 32375. [Class 34 (i)] In a rotating steam-heated appliance, the steam is projected against the inner surface of the appliance in a direction opposed to the motion thereof and at an acute angle to the tangent to the surface at the point of impact. The nozzles from which the steam is projected are located close to the lower part of the inner surface of the appliance, and are on the uprising side of the vertical central plane thereof. In one of the examples described, Figs. 1 and 2, the interior of a rotating drum A is heated by steam admitted through a compartment B1 in a stationary pipe B,. and then through distributing pipes C to a stationary steam jet pipe D from which it is discharged against the surface of the drum. The condensate is collected by a pipe E, and is removed through the pipes G to a pipe H and from the pipe H through a pipe K to the compartment B2 in the pipe B. Steam is supplied to, and condensate removed from, the pipe B through connections M and N respectively on the pipe header L. The connections M and N are equidistant from the bearing P to ensure that the steam joint Q is subjected to end thrust only. The clearance between the pipe E and the surface of the drum is adjustable by means of the adjustable links F. In the case of rotating steam-heated appliances of large diameter, the steam is supplied through the right-hand hollow journal, Fig. 4, through perforations A2 in a central stay A1 which supports the end plates of the cylinder A, and into the interior of a segmented sleeve B3 fitted loosely to the stay A1. The steam then passes to the jet pipe D, through the pipes C. The condensate is collected by a pipe E1 which rotates with the cylinder and delivers the condensate through the pipe F1 to the lefthand hollow journal. The appliance is preferably used in conjunction with a steam circulation and drainage system such as that described in Specification 429,032.

Title: Improvements relating to the dry cleaning of garments and the like
IPC: D06F43/08
Filed: 1931-11-23
Abstract: In dry-cleaning apparatus of the kind comprising a washer in which the garments or other goods are cleansed, rinsed, dried, and deodorized, e.g. that described in Specification 355,809, there is provided a solvent-reclamation unit comprising in one container an evaporator, a storage tank, a condenser, and means for venting the unit, the storage tank being supplied from the condenser by a pipe having an upper branch open at the top of the storage tank. In the unit shown in Fig. 5, the used solvent is heated in the compartment 11 by gas burners 54 or by steam coils, the vapours rise through a pipe 60 to a condenser 13, and the condensed solvent runs off through a pipe 64, a moisture trap 65, and pipes 66, 67 to the storage compartment 12; the upper part of the pipe 67 extends almost to the partition 68 and serves to vent the condenser 13 through a pipe 87 open to the air.  The solvent leaves the tank 12 by a pipe 69, Fig. 11, connected within <PICT:0392908/III/1> <PICT:0392908/III/2> <PICT:0392908/III/3> the tank to a vertical pipe open at both ends as is the pipe 67. The gases from the burners 54 pass into an inverted trough 58 about the lower end of the evaporator, and thence to the stack 59, the cross section of the trough increasing as the stack is approached.  Insulating material 73 protects the tank 12 and condenser 13 from the evaporator 11 and pipe 60.  In the complete installation illustrated in Fig. 11, the solvent in the tank 12 is passed by the pipe 69 to the usual perforated washer 7 rotated alternately in opposite directions in an outer casing, and is discharged through a trap to a sump 33 through a pipe 76 fitted with an observation glass; thence it is taken by a pipe 80, a pump 79, and a pipe 81 to the evaporator 11.  Air is then circulated by a fan 35 through a pipe 39, heater 9, pipes 18, 17, the washer 7, pipe 19, and condenser 8 back to the fan to remove residual solvent, which is drained to the sump 33 through a pipe 32 provided with a sight glass. The goods are then deodorized by partly opening the door 15, turning three-way valve 40 to shut off the heater 9 and open the pipe 38, and drawing room air through the door 15, washer 7, pipe 19, condenser 8, and fan 35, the air being discharged through pipes 36, 38.  Vent pipes 86, 88, 87 for the washer 7, sump 33, and tank 12 are provided. The water-cooled condenser 8, Fig. 4, is formed with a compartment 20 containing removable screws 21 to filter the incoming vapours; the tubes 26 contain twisted metal bands 27 acting as baffles; and the lowest compartment is furnished with baffles 28, 29 preventing liquid passing through the outlet 30 to the fan.  The heater 9 comprises a series of steam or gas-heated tubes over which the air passes; baffles in the form of sheet metal spirals may be fitted in the tubes, and baffles may be arranged in the air track.

[Class 23.] One or more of the constituents of a liquid mixture is extracted by means of a solvent or reagent projected simultaneously with it into a mixing chamber ; the products are separated centrifugally and continuous operation is maintained in successive chambers. A casing 1 can be rotated by means of a pulley 2 about a fixed hollow shaft 4 containing the pipes 6, 7, 8, 9 for the flow and return of the mixture and the reagent. The rotor shown is divided into six compartments C<1>-C<6>, each being separated from the next by three partitions of the kind shown at L <1>, M<1>, N<1>at the side of the first compartment. Nozzles f<1>-f<5> are arranged in the spaces between two of the partitions and are connected by pipes to annular jets b<2>-b<6> and nozzles c<2>-c<6> in adjoining compartments. The reagent is fed by the pipe 7 to the nozzle b<6> and travels through the rotor 1 from left to right ; it is finally drawn off by the nozzle c<1> and the pipe 9.
