Title: Improvements in or relating to the purification of sewage and industrial effluents
Inventor: GRIFFIN DENIS LASHFORD
IPC: C02F3/12
Filed: 1956-11-14
Abstract: 822,749. Treating sewage &c. gravityseparation apparatus. FILTRATION CONSULTANTS Ltd. Oct. 28, 1957 [Nov. 14, 1956], No. 34766/56. Classes 46 and 111. A sedimentation tank for the purification of liquid sewage and industrial effluents comprises an imperforate baffle 12 mounted about a pipe 7 serving to introduce the liquid to the bottom of the tank from an inlet pipe 6. A mass formed from a coagulating agent or agents is introduced into the space below the baffle 12 through the spaces between the edges of the baffle 12 and tank sides and is then raised by inflowing liquid sewage to form a coherent blanket of thickness lying between levels xx and yy. A dish shaped baffle 16 prevents the inflowing liquid from flowing directly into a sludge pipe 8 which removes sludge to a drain 9. Liquid flows through the blanket and between the baffle 12 and tank sides, passing over a weir 5 into a channel 2 and thence through a pipe 4 to filter beds (not shown). Vent pipes 13 and 13a conduct away gaseous and liquid impurities respectively. The coagulating agent is prepared by adding sodium aluminate or lime to a solution of aluminium sulphate in water, the pH of the resultant aluminium hydroxide-containing mass being adjusted if necessary, in the latter case, by addition of more lime or aluminium sulphate. During operation, lime can be added to check putrefaction of impurities at the bottom of the tank, and blanket-forming material can be added to replace that removed with the sludge. Both are added through removable pipes (not shown). In the Provisional Specification the position of pipes 13 and 13a, and the shape of baffle 12, are modified slightly, and there is no baffle 16. Specification 780,630 is referred to.

Title: Improvements in or relating to power operated eyeletting machines
IPC: A43D100/02
Filed: 1920-12-09
Abstract: 176,519. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). Dec. 9, 1920. Setting eyelets; setting-mechanism. - In an eyeleting-machine which automatically feeds and sets eyelets without punching the work by a previous machine cycle, in work fed by the operator, the eyelets are fed down the raceway 50, arriving at the end in the upright position, the end eyelet being held by a spring latch 58. The raceway oscillate to bring the end eyelet under the setting-tool 14 as it makes its downward stroke, and leaves the eyelet engaged on the end of the spring-plunger 18. As the tool 14 continues its stroke, the eyelet is clenched in the work by pressing it on the anvil 20 carried by the bracket 22. The setting-tool is connected to the arm 34 of an actuating lever by links 36 pivoted at 42 to the lever. The top of the lever is counterbored at 40 in order to form flanges engaging the top of the links. This enables a strong downward thrust of the setting-tool to be obtained without shearing the pivot-pin 42. The other end of the arm 34 is integral with the yoke 30 carrying the pivot 31 and having another arm 44, connected to the arm 46 eccentrically pivoted on the disc 28 driven by the shaft 24. Eyelets, feeding.-The eyelets are put into the hopper 52 in which a brush 80 is revolved by the pulley 86 by means of the belt 88 passing over the idlers 90 and round a pulley on the main shaft 24. The shaft 82 of the brush has notches 96 cut in it, with ratchet teeth, as shown in Fig. 3, to engage a spring stud 98. A knob 94 enables the operator to rotate the brush 80 manually, to fill the raceway, the direction of rotation of the brush being opposite to that imparted by the pulley. The eyelets enter the raceway in an inverted position, from the hopper, and are delivered to the plunger 18 in the upright position. The raceway is pivoted by the removable pin 56 to a bracket 12' on the machine frame 10 and is oscillated by a shaft 60, to which it is adjustably connected by the arm 64 by the removable pin 72. By removing the pins 56, 72, the raceway and hopper, which oscillates with it, may be removed to expel eyelets when a fresh kind is required for the work. The shaft 60 has an arm 62 carrying a roller 66 working in the cam groove 68 in the disc 28. This disc actuates both the raceway and the setting-tool, and adjustment of the arms 62 and 64 enables their movement to be accurately timed for setting the eyelet.

Abstract: The invention comprises compounds of formula <FORM:0975291/C1/1> wherein X is halogen, alkoxy, alkoxycarbonyl or nitro, Y is alkoxy, R1 and R2 are H or alkyl, R3 is optionally substituted branched-chain alkyl (but specifically excluding those compounds in which X=Y=CH3O-, R1=R2=H and R3=i-Pr, t-Bu, alphamethylbenzyl or 1-methyl -3-phenylpropyl) and salts thereof. A number of general methods of preparing the compounds are described. In examples (1)-(5), the following are prepared by reacting NaBH4 with the appropriate phenylglyoxal in presence of isopropylamine: R1=R2=H, R3=i-Pr and (1) X=Y=EtO, (2) X=MeO, Y=n-BuO, (3) X=MeO2C, Y=MeO, (4) X=MeO,Y=EtO, (5) X=Cl, Y=EtO; the required phenylglyoxals are prepared by oxidation of the corresponding acetophenones with SeO2. In examples (6), (7) and (9) the reaction product of isopropylamine, butylamine or 2-amino -2- methylpropanol-1 with 4-ethoxy -3- nitrophenacyl bromide is reduced with NaBH4 giving compounds R1=R2=H, R3=i-Pr, t-Bu or hydroxy-t-Bu, X=NO2 and Y=EtO; the required phenacyl bromide is made directly from the acetophenone by bromination. In Example 8, the compound R1=H, R2=R3= i-Pr, X=NO2 and Y=EtO is made by reaction of a mixture of 1-(4-ethoxy -3- nitrophenyl) -2- bromoethanol and 4-ethoxy -3- nitrophenyl ethylene oxide with diisopropylamine. In Example 10, 3,4-diethoxyphenyl 1-hydroxyiminoethyl ketone is reduced (H2/Pt) in presence of acetone giving the compound R1=Me, R2=H, R3= i-Pr, X=Y=MeO. In Examples 11 and 12, the compounds R1=Me, R2=H, R3=i-Pr or 1-methyloctyl, X=Y=EtO were prepared by reduction (H2/Pd-C) of a mixture of 1-(3, 4-diethoxyphenyl) -2- aminopropanol and acetone or 2-nonanone. The mixture required for Example 8 is prepared by reacting NaBH4 with 4-ethoxy-3-nitrophenacy bromide.  It is stated that the compounds of the invention possess b -adrenergic blocking activity but not sympathominetic activity and are therefore useful for the treatment or prophylaxis of coronary artery disease.  They may be used, together with a diluent or carrier, in the form of tablets, capsules, aqueous or oily solutions or suspensions (which may be injectable) or dispersible powders. Suitable diluents are specified and examples are provided.

Abstract: 503,259. Cigarette-making machines. AMERICAN MACHINE & FOUNDRY CO. Dec. 20, 1937, No. 35191. Convention date, Oct. 6..[Class 130] In a cigarette-collecting mechanism for continuous-rod machines, in which cigarettes travel endwise on a delivery belt 7 and the leading cigarette or cigarettes are displaced laterally on to a collecting belt or belts 40 by a member 15 reciprocated laterally, the member 15 is arranged to produce an air current to bring the cigarettes into engage. ment with a retarding surface on the member in order to check their lengthwise movement. As shown, the member 15 is an inverted trough formed by members 16, 17 and a lining strip 28 of frictional material such as sponge rubber, and is secured to a pair of connecting-rods 19, which at their other ends are connected to crank pins of a pair of cranks 21 on a shaft 22 and intermediately to rocker arms 20. The pivots 23 of the rocker arms 20 are adjustable by means of screws 25. so that, during the lateral movement of the trough, the strip 28 may come into gripping engagement with the cigarettes or may remain out of engagement. In the latter case, a. current of air created under the edge of the trough by the forward movement tends to lift the cigarettes into braking contact with the strip 28. Instead of the lining strip 28, perforations may be provided in the top and the rear wall 16 of the trough. Endwise movement .of the foremost cigarette may be arrested by an abutment at the end of the trough, and such movement of the second cigarette by a movable stop 30 pivoted on a bracket 31 on the trough. The stop 30 is connected to a rod 32 passing through a pivotally supported block 33 and provided beyond the block with a light spring 36. The stop 30 is thus swung out of the path of the first cigarette and into the path of the second ; the cigarettes do not encounter the stops until they have been moved - laterally from the bolt 7. The means for delivering the. cigarettes from the cutting mechanism include plates 2, 3, Fig. 7, with inclined faces 4 against which the cigarettes are held by a leaf spring 5; in advance of the plates 2 and spring 5, the cigarettes are pressed on the belt 7 by a segmental roller, the belt and the roller being driven at surface speeds greater than the speed of the cigarette rod in order to effect a longitudinal separation of the cigarettes before their lateral .displacement by the member 15.
