Title: Improvements in and relating to planing machines
IPC: B23D1/18
Filed: 1951-05-17
Abstract: 686,087. Planing. WALDRICH, O. May 17, 1951 [May 17, 1950], No. 11586/51. Class 83 (iii). A planing machine cutting on the forward and return strokes has a pair of semi-circular tool-carrying rams 9, 10 which are moved alternately to and from the work and at the same time rotated through about 180 degrees so that the tool or tools 50 on one ram are interchanged into the same working position as that previously occupied by the tool or tools on the other ram, but facing in the opposite direction, the rams being clamped in the tool head during each working stroke. The rams are mounted in a casing 7 pivoted on the tool head 6 and are rotated by a toothed wheel 11, the angle of rotation being normally limited to 180 degrees by the sloping faces of one or other of two abutments 17 engaging the sloping ends of a groove in the wheel hub, but, by adjusting the abutments back slightly, this angle can be increased so that a series of tools mounted behind one another in each ram can make staggered cuts. Rollers 30 carried by the ram are engaged in a cam groove 28 in a sleeve 26 on the end of a spindle 22, in order to give the movement to and from the work, and the spindle is adjustable by a motor 24 and gearing 25 driving a nut engaging the spindle in order to set the cutting depth. To ensure accuracy of this adjustment, stop members 58 may be fitted at the top of each ram and the spindle 22 may be resiliently connected to the sleeve 26 by a flange 60 and bolts with disc springs under their heads so that, before the lowest point of the cam groove is reached, the stop member 58 on the lower ram engages a collar 56 resting on a shoulder of the spindle and the final movement of the rams causes the sleeve 26 to yield upwards and hold the stop member and the collar abutting under the pressure of the springs. The rams are clamped by split tapered sleeves 38 which are pressed inwards by disc springs under the heads of bolts securing rings 38 to the casing 7 and are released by hydraulic rams forcing the sleeves outwards. For clamping other parts of the machine, for example, the tool head to the beam, similar bolts and disc springs may be employed and hydraulic pressure may be applied to the heads of the bolts to release the clamping. The hydraulic pressure may be controlled by the movement of the rams or of the machine table. A screwed spindle 31 inside the spindle 22 is provided for adjusting a sleeve 32 to withdraw a key 34 upwards so that the sleeve 26 is disengaged from the spindle 22 and can be rotated with the rams through 180 degrees, thus changing over the rams for feeding from left to right instead of right to left. Balls projecting from bores in the sides of each abutment 17 deflect a lever 52 and operate an electric contact 54 so that the motor driving the machine table can operate only when the wheel 11 has engaged the abutments. Motors 45 and 46 move the tool head slowly and rapidly, respectively, a motor 47 operates the hydraulic clamp-releasing means and motors 48 and 49 move the abutments 17.

Abstract: Diglycidyl thioethers of general formula <FORM:0754015/IV(a)/1> in which <FORM:0754015/IV(a)/2> where n=0-50, are prepared by reacting an excess of epichlorhydrin in presence of an alkali, preferably added in increments during the reaction, on a dithiol produced by reduction of a polymer from dichlorethyl formal and an inorganic polysulphide.  Reaction is preferably carried out in an organic diluent which is distilled off, and the residue dissolved in a water-immiscible solvent, e.g. toluene or methyl isobutyl ketone is worked with water and recovered by removing the solvent by distillation.  The glycidyl ethers may be polymerized in presence of alkaline catalysts such as sodium or potassium hydroxide, triethylamine or benzyldimethyl amine.  They also react with polyfunctional labile hydrogen-containing materials many of which are mentioned to form resins or rubbers.  Among the polyfunctional materials mentioned are glycidyl ethers of polyphenols and mixtures thereof with dibiasic acids.  They may also be used as internal plasticizers in the hardening of resins from the diglycidyl ethers of diphenylol methane or diphenylol propane. Examples describe the preparation of glycidyl ethers from products of the formula HS(CH2CH2OCH2OCH2CH2SS)n CH2CH2OCH2OCH2CH2SH having molecular weight of about (1) 300; (2) 600; (3) 4000 and (4) 1000.  In Example 4 the reaction was performed in an atmosphere of nitrogen.  The product of Example (4) is:-4(a) hardened to a gel with benzyldimethylamine; 4(b) hardened with benzyl dimethylamine in admixture with the dithiol used as starting material in Example (4); 4(c) hardened together with the reaction product of excess diethylene triamine with the diglycidyl ether of 4,41-diphenylol-dimethylmethane; 4(d) mixed with poly-(phenylolmethane) and gelled with benzyldimethyl amine; 4(e) gelled with diglycollic acid; 4(f) hardened with diethylene triamine; 4(h) reacted with excess diethylene triamine to form a catalyst for hardening a further quantity of the diglycidyl thioether; 4(i) mixed with the diglycidyl ether of 4,41-diphenylol dimethylmethane, the mixture then being hardened with a secondary curing catalyst prepared from 4 mols. of diethylene triamine and 1 mol. of the diglycidyl ether of 4,41-diphenyloldimethylmethane.

Title: Air-cooled internal combustion engine
Inventor: FLATZ EMIL
IPC: F02B75/22
Filed: 1950-05-17
Abstract: 693,828. Purifying air; cooling; supercharging. KLOCKNER-HUMBOLDT-DENTZ AKT.-GES. May 17, 1950, No. 12389/50. Class 7 (ii). In an air-cooled internal-combustion engine comprising two rows of cylinders, a cooling fan 10, Fig. 1, and a scavenging or charging fan 11. the two fans are arranged at opposite ends of the engine between the cylinder rows or beyond the corresponding ends of the rows, the fans being coupled together and commonly driven. The two rows of cylinders are arranged at an angle of 90 degrees to one another, the cylinder barrels and heads being provided with cooling fins; each fan shaft lies parallel with the longitudinal engine axis, both fans being interconnected by a shaft 14 and driven from the crankshaft 5 through gearing 15, 16, torsion shaft 17, gearing 18, 19 and 20 and centrifugal clutch 21, the latter taking up the fan drive when the engine speed is above a given value. The axial cooling fan 10 takes in air through intake 22 with guide blades 23 and delivers it to a chamber 26. between the cylinder rows, through a branch 24 also provided with guide blades 25, the air from chamber 26 being directed around the cylinder, each of which latter are enclosed by guide plates. A part of the air in chamber 26 tangentially enters a separator 27 where, due to the whirling motion of the air, any impurities are carried away through an opening 32, the bulk of the air returning in a clean state to the intake 30 of the radial scavenging fan 11. the diffuser 34 of which is connected to the cylinder. The intake to the fan 11 may, however, be taken directly from some point external to the chamber 26. In a modification, the drive from the crankshaft 103, Fig. 5, of a two-stroke diesel engine, with its cylinder in V formation, is taken to the cooling fan 101, by means of spur gearing, 104, whilst the scavenging fan 102 is driven from the cooling fan through a shaft 110 and a step-up transmission 111 so that it runs at a higher speed than the cooling fan, which latter draws its intake air through a filter 108. In the case of four-stroke engines a charging blower may replace the scavenging fan. Specification 671,152 is referred to.
