Abstract: 462,094. Treating sewage. TRIGGS, W. W. (Dorr Co., Inc.) May 27, 1936, No. 14952. [Class 111] [Also in Group XXX] Apparatus for treating sewage and like sludge comprises means for adding reagent to the sludge, a mixing chamber 15, a rotary vacuum or other filter 52 for de-watering the sludge and a bucket elevator 36 for raising the sludge from the mixing chamber to the trough 51 of the filter, all these parts being supported on a framework comprising horizontal and vertical beams 11, 13, and a cover 14 for the mixing-chamber. The mixing-chamber is divided into communicating sections 19, 20 by a partition 21 and the sludge is supplied to the section 19 which has vertical baffles 22 by a pipe 30. Reagents such as milk of lime and ferric chloride are supplied through pipes 28, 29 respectively and are thoroughly agitated with the sludge by air admitted through perforated or porous tubes 26, 27. The sludge and reagents are supplied to the mixing- chamber by pumps driven intermittently by electric motors, the current to which is controlled by a float in a chamber connected to the section 20, the float closing or opening a switch when the liquid level reaches a higher or lower limit respectively. The pump for the sludge is of such capacity that while the pump is operating the sludge will be supplied at a greater rate than it could be disposed of by the apparatus. The buckets 42, Fig. 3, of the elevator, which dips into a sump in the section 20, have a filling opening 47 at the front, one end being completely closed and the other open at the top 46 so that, when overturned at the top of their travel, the buckets deliver the sludge sideways into a hopper 48 connected with the filter trough 51 by a pipe 50. An openended pipe 53 is pivotally mounted in the side of the hopper 48 so that it serves as an overflow control to regulate the liquid level in the filter trough. A motor 71 drives pumps 67, 69 for drawing air and liquid respectively from the filter, and also a compressor 72 which supplies air to the tubes 26, 27 and for blowing-back through the filter. Another motor rotates the filter and drives the elevator.

Title: Constant volume regulator for turbo compressors
IPC: F04D27/02
Filed: 1921-05-31
Abstract: 183,314. Marks, E. C. R., (Ingersoll-Rand Co.). May 31, 1921. Regulating and controlling.-A turbocompressor is driven by a motor the speed of which is controlled by a constant volume regulator consisting of a float 6 in a receptacle 7, the inside of the float and the inside of the recep. tacle 7 being connected by pipes 9, 10 to a Venturi tube forming the intake of the compressor. The valve 4, which admits fluid to the motor operating the compressor, is directly connected to a piston 20 controlled by a pilot valve 19<a> which is operated through linkage 18, 19 from the float 6. A stem 11 is attached to the top of the float and also to a bell-crank lever 12 which is connected to the link 18 and to an adjustable spring 13 to balance the pressure difference between the inside and outside of the float, and the weight of the float. A water seal is arranged between the stem 11 and the top casing 15 of the receptacle. The inside of the float is connected by the pipe 9 to the throat 3 of the Venturi tube 1 and the receptacle 7 is connected to the part of full diameter, and the difference in pressure varies as the square of the velocity and therefore with the quantity. The admission valve 5 of the motor occupies a definite position, according to the setting of the spring 13, for a particular flow through the compressor intake 1. If there is a decrease in the resistance of the apparatus supplied, the fluid velocity through the compressor and consequently the pressure difference on the float will increase.. The float is moved down and the valve 5 is partly closed to decrease the fluid admitted to the motor to diminish its speed. A dashpot 24 is attached to the link 18 to steady its action. When the safe speed of the motor and compressor is exceeded the valve 5 is closed by a centrifugal governor.

Filed: 1973-03-30
Abstract: 1358027 3 - Heterocyclic α - amino - phydroxybenzyl cephalosporins SMITHKLINE CORP 30 March 1973 [14 June 1972 15 Sept 1972] 15308/73 Heading C2A Novel α-amino-p-hydroxybenzyl cephalosporins having the Formula (I) and salts thereof, wherein R is 5-methyl-1,3,4- thiadiazol-2-yl or 1-methyl-5-tetrazolyl are prepared by (1) N-acylating a 7-aminocephalosporin compound of Formula (II) or a carboxyl-protected ester or alkali metal salt thereof, wherein X is -S-R and R is either as defined above or is a group -OCOCH 3 , with α-amino-p-hydroxyphenylacetic acid or an N-acylating active derivative thereof, the -OH and -NH 2  groups being protected if necessary, and (2) when R is the group -OCOCH 3 , reacting the product with a heterocyclic thiol: HS-R or an alkali metal salt thereof, in which R is as defined above in connection with Formula (I), followed by (3) removal of any protecting group or groups. The sequence of reactions (1) and (2) may be reversed, i.e. 7-aminocephalosporanic acid or its salt or ester being reacted at the 3- position with the said heterocyclic thiol followed by N-acylation of the product with α- amino-p-hydroxyphenylacetic acid or its active derivative, with subsequent removal of any protecting groups. Protective groups used are conventional amino-, hydroxy- and carboxyl-protecting groups which are removable by, e.g. hydrolysis or hydrogenolysis. The N-acylation is usually performed with the acid itself in the presence of a condensing agent, or with a typically activated derivative of the acid. The 3-position replacement may be effected by reacting the amino-protected cephalosporin or its alkali metal salt with the thiol or its salt, at a pH near neutrality in acetone or aqueous acetone at elevated temperature. The product may be recovered by slight acidification of the reaction mixture followed by extraction with an immiscible solvent. Since the compound (I) has both acidic and basic groups, its salts may be base- or acidaddition salts; alternatively the compound may be in zwitterionic form. The compounds (I) and their salts have broad spectrum anti-bacterial activity and may be made up into various pharmaceutical compositions (e.g. for oral or parenteral administration) with the aid of an appropriate carrier, diluent or excipient.

Abstract: 1504231 Printers OKI ELECTRIC INDUSTRY CO Ltd 14 April 1976 [22 April 1975] 15322/76 Heading G4H Images, e.g. pictures or characters are printed with gradation levels including at least one intermediate gradation level by supplying signals indicating the levels from a buffer memory to circuitry also responsive to timing signals this circuitry feeding memory elements which correspond one-to-one with printing elements. As disclosed intensity codes for the elements of a line of a matrix decomposition of the required image are supplied to the circuitry ten times and combined with a different timing signal each time to produce outputs via the (eight) memory elements to eight thermal print elements, so that each print element receives a pulse in a number of the ten time intervals corresponding to the value of the intensity code for that element in this line, the correspondence being non-linear to compensate for non-linearity of the printed intensity as a function of print element energization duration. The circuitry can use a comparator, or decode the intensity code to feed gates also receiving the timing signals. The other lines of the matrix decomposition are dealt with in turn similarly. Different gradation levels can be alternatively achieved by controlling the dimensions of the elements of the matrix decomposition.
