Abstract: The invention relates to penicillins of the general formula <FORM:0873049/IV (b)/1> where X is an amino-substituted acyl group containing up to 20 carbon atoms and having the formula <FORM:0873049/IV (b)/2> where R is hydrogen or an amino, carboxyl or substituted or unsubstituted alkyl, aryl, aralkyl or heterocyclic group, and n is zero or an integer, and non-toxic salts thereof.  X may be <FORM:0873049/IV (b)/3> where n is zero or 1 to 6, and R is hydrogen or an alkyl, aryl, aralkyl or heterocyclic group which may be substituted; R being phenyl, chlorophenyl, methoxyphenyl, furyl or cyclohexyl when n is zero <FORM:0873049/IV (b)/4> <FORM:0873049/IV (b)/5> where n is 1 to 4.  Typical penicillins are a -aminobenzyl penicillin, a -amino-p-methoxybenzyl penicillin, a -amino-2-furylpenicillin, a -aminoheptylpenicillin, a -aminopentyl penicillin, a -aminocyclohexyl penicillin and a -amino-p-chlorobenzyl penicillin.  The non-toxic salts are, e.g. the sodium, potassium, calcium, aluminium, ammonium and substituted ammonium salts, e.g. salts of trialkylamines, procaine, dibenzylamine, N-benzyl-beta-phenylethylamine, 1-ephenamine, N,N1-dibenzylethylene diamine, dehydroabietylamine and N,N1-bis-dehydroabietylethylene diamine.  The penicillins are produced by reacting 6-aminopenicillinic acid with an acid of general formula XOH (where X is as defined above) having its amino group or groups protected, or a salt thereof, and thereafter removing the protecting group or groups under sufficiently mild conditions to avoid destruction of the penicillin nucleus.  The acid may be in the form of a mixed anhydride prepared by reacting the amino-substituted carboxylic acid, or a salt thereof, having its amino groups protected, with an ester of chlorocarbonic acid.  The protecting group may be a trityl group or a group of general formula R11O.CO- where R11 is an alkyl, benzyl, substituted benzyl, phenyl or substituted phenyl group.  The protecting groups may be removed by catalytic hydrogenation using palladium on a barium carbonate support.  Specifications 870,395 and 870,396 are referred to.

Title: Method of and apparatus for continuous filtration of brewers' mash
Inventor: SHORE DAVID TEIGNMOUTH
IPC: C12C7/14
Filed: 1958-10-07
Abstract: 929,835. Filtration of brewers' mash. A.P.V. CO. Ltd. Oct. 2, 1959 [Oct. 7, 1958], No. 32023/58. Class 14 (2). [Also in Group I] In filtering brewers' mash using the grain as a filter bed, a charge of mash is fed into a mash tun, the mash tun is moved through a number of operating stages wherein recycled wort or sparged liquor is fed into the tun and clarified or partially clarified wort is withdrawn from the tun, the spent grain is discharged from the tun and the cycle is repeated, in which the flow of wort through the bed and the differential pressure across the bed are controlled in each of the stages to provide the required flow characteristics while avoiding undue collapse of the bed. The various operating stages (corresponding to those commonly used in the production of wort in a static mash tun) are diagrammatically represented in Fig. 1 (not shown). Referring to Fig. 4, mash tuns 1 have spigots which are carried in bearings 27 mounted on a rotating spindle 29; the outer ends of the bearings 27 carry rollers 27a running in a stationary track 30a. The exit pipes 32 of the tuns are connected to outlets 35 through co-operating openings in valve rings 33 and 34; ring 33 is rigid with the rotating spindle and ring 34 is stationary. The tuns are periodically overturned by a control plate (not shown) for discharging the spent grain preparatory to the commencement of a further cycle. It is stressed that suction is not applied directly to the filter beds in the tuns, since this would give rise to undue collapse of the bed. The flow of liquor and the differential pressure across the bed at each stage are controlled from a control panel 39, Fig. 3 (not shown). It is stated that in some cases the operation of valves may be controlled by the movement of the mash tuns and that the operations are readily adaptable for an entirely automatic control.

Title: Improvements relating to the manufacture of condensation products from phenols and formaldehyde
IPC: C08G8/28
Filed: 1928-11-05
Abstract: 324,913. Hessen, R. Nov. 5, 1928. Phenol-aldehyde condensation products are obtained by mixing the components in molecular proportions, condensing them by refluxing in the presence of a basic contact substance, removing the resulting aqueous layer from the resinous layer, adding further amounts of formaldehyde (one-third to one-quarter of the amount originally used) to the resinous layer, condensing and again removing the aqueous layer, these three latter operations being repeated two to four times until no free phenol remains in the resinous layer. In the subsequent additions of formaldehyde, a further amount of basic contact substance may also be added. After removal of the catalyst by neutralizing and washing, the resulting resins are relatively thin liquids, and are easily freed from water by evaporation. The solid resins are water-clear, soluble in alcohol, acetone, caustic soda, &c., and may be hardened by heating to temperatures commencing at about 60‹ C. Examples are given.

Abstract: 537,408. Making explosives. HERCULES POWDER CO. Dec. 14, 1939, No. 32259. Convention date, Feb. 14. [Class 9 (ii)] In processing smokeless powder grains, the operations of treating with a gaseous medium to remove the excess solvent, then with a liquid to remove residual solvent, and then with a gaseous medium to remove the liquid, are effected while the grains are located in a single receptacle. In the form shown, the powder receptacle 1 has a gas-tight charging cover 3 with funnel 5 leading to a spreader 8, 9, concentric rings 13 for ensuring even distribution, and a funnel-shaped false bottom leading to an outlet valve 14 that controls the passage of the treated powder to a screen 25. Before, during, and after charging a valve 17 is set so that a fan 18 circulates heated air through the receptacle and out through a condenser 20 for recovering the excess solvent. The valve 17 is then closed and hot water is admitted through a valve 21 the cover 3 being removed to allow the vapours to escape, residual solvent being thus removed. After draining the receptacle, air drying is effected by setting the valve 17 so that air is blown into the receptacle through a heater 24 by a fan 23, the heater being finally turned off to reduce the powder to room temperature. The powder is then released to the screen 25 through the valve 14.

Filed: 1933-11-21
Abstract: 429,181. Field control of D.C. motors. GENERAL ELECTRIC CO., Ltd., and COLLETT, E. P., Magnet House, Kingsway, London. Nov. 21, 1933, No. 32491. [Class 38 (iii)] When a motor is first connected to its supply, its field excitation is reduced by the omission of the excitation of a field winding, or by varying the field ampere turns pro. duced by the current flowing in a field circuit under the control of a controller segment, the field excitation being subsequently increased before all the series starting resistances are cut out. At the first position of the controller a motor 1 is connected to the line with armature resistance 8 in circuit, and a diverter resistance 14 across the series field 13. At the next position the contactor 15 is opened and the motor has full field. Thereafter the resistance 8 is cut out in steps by contactors 9, 10, 11, 12, and the diverter resistance again connected and reduced in steps by contactors 15, 16, 17. When the controller is moved back the contactor 15 may be prevented from closing on the first step so that a low speed running position is obtained. When a compound motor is employed the reduction of the field when the motor is first connected may be effected by cutting out the shunt field. With seriesparallel control the field may be similarly controlled for the first parallel step.

Abstract: A polymerizable composition comprises divinyl benzene dioxide and an amine which has at least 2 active amino hydrogen atoms attached to the same or different nitrogen atoms.  The unpolymerized or partially polymerized compositions, alone or in a solvent, are stable for long periods before being finally cured. Specified amines are primary alkyl, aryl, aralkal, alkaryl and cycloaliphatic amines, including polyamines; polyamides; amino-alcohols and -phenols; addition products of polyamines and epoxides; and heterocyclic amines.  Many examples of such compounds are given.  Hard resins are obtained when 0,3 to 3 amino hydrogen atoms are provided for each epoxy group of the diepoxide.  When the proportion is 1 to 3 hydrogen atoms per epoxy group, resins having potential use as anion exchangers are obtained.  3 to 5 amino hydrogen atoms per epoxy group yield resins which can be further reacted with polyepoxides, e.g. divinylbenzene dioxide or diglycidyl ether of bis-phenol.  Less than 0,2 amino hydrogen atoms per epoxy group yield liquid resins which can be hardened by polymerization with active hydrogen compounds such as polyamines, polyhydric phenols, polycarboxylic acids or their anhydrides.  More than 5 amino hydrogen atoms per epoxy group yield viscous or tacky products. Catalysts may be added to the compositions, e.g. metal halide Lewis acids, alcohols, phenols and alkali metal hydroxides.  These may be added in solvents.  The compositions may include fillers and pigments, e.g. talc, wood flour, alphacellulose, titanium dioxide, antimony oxide, zinc oxide and carbon black.
