Title: Improvements in or relating to horizontal hydraulic broaching machine
IPC: B23Q5/06
Filed: 1940-07-22
Abstract: 541,388. Hydraulic broaching machines. LAPOINTE MACHINE TOOL CO., Ltd. (Lapointe Machine Tool Co.). July 22, 1940, No. 12006. [Class 69 (ii)] [Also in Group XXII] The head 14 of a horizontal broach B is actuated hydraulically by means of a piston 11 in a cylinder 10 the supply of liquid to which is effected by a reversible discharge pump P controlled by electrically operated hydrauric means to set the pump for strokes to effect a cut, to return, or for idle operation switches, 100, 101, which are adjustable in position, being operated at the end of each cut or return stroke to release the electrically-controlled hydraulic means. The machine may be set to operate continuously by closing a switch 103, or to make one complete cut and return stroke by closing a switch 102, or the cut and return strokes may be started independently by means of switches 104, 105, and a switch 106 may stop the machine in any position, and the machine stops automatically if the electric supply fails. The pump P is controlled by a pinion 35 and rack 36 operated by a piston 38 in a cylinder 40 which is supplied with oil by an auxiliary pump p<SP>1</SP> under control of a valve V<SP>2</SP> operated by electric magnets 44, 45 which are energized alternately under control of relay switches R, R<SP>1</SP> operated by electromagnets S, S'. The piston 38 is self-centred and maintains the pump P inoperative when neither of the magnets 44, 45 is energized. Stops 160, 161 are set to control the rate of flow of the liquid from the pump P and thus the speed of action and return of the broach. A valve V3 is operated by an electromagnet 56 to byepass the cylinder 10 when the pump P is inoperative, and in this position the ends of the cylinder 10 are vented by means of a valve 81 in a cylinder 30 fitted with a piston valve 70 which is moved by liquid supplied by the auxiliary pump via the valve V<SP>2</SP> to assume the position shown in Fig. 2 when the piston 11 is moving to the right to effect a broaching action, and is moved to the left when the return return stroke takes place. The piston rod 12 is hollowed to receive a fixed tubular rod 16 mounted in the cylinder 10. During the " cut stroke the liquid enters cylinder 10 via a pipe 18 and leaves the cylinder in part through the valve 70 to a backpressure valve 86 which discharges into a reservoir T, and in part via tube 16, passages 22, 20 and pipe 19 to the exhaust of the pump, the pasage 20 also receiving fluid via a passage 23, check valve 32 and a passage 21. During the return stroke liquid from pipe 19 enters the right-hand end of the cylinder 10 via passages 20, 21, 22 and leaves the left-hand end of same via pipe 18 and passage 26, and valve 70 from which liquid returns to the right-hand end via passages 25 and 23, this means being similar to that described in Specification 495,836. The return takes place more quickly than the cut. Specification 495,938, [Group XXII], is referred to.

Title: Process for sewage treatment
IPC: C02F1/72
Filed: 1935-04-23
Abstract: Air is blown into residuary water or sewage tank effluent in presence of powdered or granulated activated carbon under conditions such that mechanical rubbing of the carbon particles against each other renews their surfaces and a part at least of the carbon passes into a highly dispersed state favouring the formation of colloidal complexes of carbon, oxygen and organic matter.  The rubbing of the particles may be caused by mechanical agitation.  The carbon used may be coated or impregnated with metallic oxides or salts easily subject to hydrolysis, e.g. salts of iron, chromium, cobalt, nickel, manganese gold or copper.  The liquid after separation from the carbon by straining is treated with a flocculating agent, such as acids, alkalies, ferric sulphate, aluminium sulphate or sodium phosphate, and the precipitate is separated by decantation or filtering.

Title: Blast-refined steel with low carbon content and method for producing same
IPC: C21C5/28
Filed: 1950-05-17
Abstract: In a method of refining steel having a carbon content below 0.015 per cent, an oxygen-containing gas free from carbon is blown on to or through the melt in the presence of a reducing agent having a higher affinity for oxygen than has iron, at least one of the elements nitrogen or phosphorus being present in the melt or added during the blowing.  The reducing agent may be silicon or a silicon alloy in amount which, during refining, does not exceed 0.5 per cent, or phosphorus in the presence of lime.  The amount of phosphorus should be such that the carbon is reduced to 0.04 per cent before the phosphorus has fallen below 1.5 per cent. Ferrophosphorus may be added.  The finished steel may have 0.006-0.150 per cent phosphorus, or 0.010-0.030 per cent nitrogen and if both nitrogen and phosphorus are present the sum of the phosphorus content plus 10 times the nitrogen content may be between 0.15 and 0.30 per cent.  The reducing agent may be added in portions during the blowing and the final part of the blow may be nitrogen alone.  Steels made by the process are stated to give good impact values at low temperatures, e.g. 14-15 kilogram-meters at minus 60 DEG C in the normalized, strained and aged condition.
