Title: Apparatus for grooving and cutting off the socket of pipes made of clay or like material
Inventor: PAAPE FRIEDRICH
IPC: B28B11/16
Filed: 1969-01-09
Abstract: 1,210,334. Grooving extruded clay pipes. KERAMIKMASCHINEN GORLITZ VEB. 9 Jan., 1969, No. 1315/69. Heading B5A. [Also in Division F2] Apparatus for grooving and trimming the socket 6 formed on the end of an extruded clay pipe, comprises a rotatable disc 18 mounted for rotation about a journal 2 mounted on a table 1 located below the end of the pipe socket, said disc having a greater diameter than the external diameter of the pipe socket, a vertical shaft 21 extending through said disc, a double-armed lever 22 mounted on the lower end of said shaft, an hydraulic piston and cylinder-assembly 23 connected to one end of said lever, a resilient return device 24, 28, 30 connected to the other end of said lever, a lever arm 26 carrying a grooving roller 27 connected to the upper end of said shaft and means for cutting the socket to the desired length. A drum 20 is provided on the upper side of the disc 18 and cutter element 33 comprising obliquely arranged blades of variable inclination are attached to arms 31 of adjustable length mounted on the drum. Disc 18 is surrounded by a vertical wall 5 on which elements 9 defining the pipe socket walls are mounted and an arm 39 extruding through a gap in the wall 5 removes cut-off clay sections from the rotating disc. The disc is driven by hydraulic motor 15 acting through gear chain 13, 14, 12 on hubs 10, 11 attached to the disc and the piston and cylinder assembly 23 is actuated by fluid supplied through passages 34, 35, 36 in the journal 2 and bearings. In operation a clay pipe is extruded into contact with the fixed pattern 3 and forms a socket 6 as shown. The cutter blades 33 are rotated and strip clay from the bottom of the socket forming a clean edge. Extrusion is stopped and hydraulic fluid pushed into piston and cylinder 23, compressing spring 30 into container 28 and forcing the grooving roller 27 gently into contact with the pipe, the rotation of the apparatus forming the grooves. The hydraulic pressure is released through a constriction so that the return spring 30 moves the roller 27 slowly away from the pipe socket.

Title: Improved manufacture of catalytic agents
IPC: B01J21/00
Filed: 1923-01-17
Abstract: A hydrogel which when dried produces a gel having pores of such size that 30 DEG  C. and 22 m.m. partial pressure of water vapour it contains 21 per cent of water; is treated with a dilute solution of alkali, such as caustic soda, so as to adsorb the alkali, and is then after washing treated with a dilute solution of a salt of a metal capable of forming a catalyst so that an oxide of such metal is precipitated within the hydrogel, after which the hydrogel is washed and dried.  The product may be treated to reduce the catalytic metal compound to the metallic state.  The invention is described with reference to silica hydrogel, but is stated to be applicable to the hydrogels of other substances, for instance tungstis acid, stannic oxide, and alumina.  The drying may be effected at 75-120 DEG  C. with or without a further heating to 400 DEG  C., or the material may be placed in a vacuum, with or without heat.  In an example silica hydrogel is soaked in sodium hydroxide solution of between .05 N. and .005 N. strength for 8 to 10 hours, washed, and then soaked in a 0.1 molar solution of ferric nitrate for 5 to 6 hours and is finally washed and dried. During the drying nitrogen oxides are expelled from the basic ferric nitrate present in the gel.  A gel of this kind is said to give a 90 per cent conversion to sulphur trioxide of a 7 per cent mixture of sulphur dioxide and air.  Specifications 136,543 and 212,065 are referred to.

One end of a tension spring 16 is anchored to a pin 15 on the arm 14, while the other end is anchored to a threaded tension adjusting rod, so that the spring 16 balances the torque of the shaft 1 due to the gyroscope. Another member is clamped to the stub-shaft 1 and has an arm 21 parallel to the arm 14<SP>1</SP>. A sector-plate 22 with arcuate slot 23 pivots on the shaft 1 between the arms 14<SP>1</SP> and 21, which are joined by a pin 24 passing through the slot 23. A second spring 30 is anchored to the sector 22 and to a threaded tension adjusting rod, so that for greater angles of rotation when the pin 24 engages the end of the slot 23, the spring 30 assists the spring 16 in balancing the torque of the gyroscope.

Various polyacids, other polyols and monoacids which may be used to prepare the alkyd are specified. The alkyd may be applied as a dispersion in an inert liquid carrier, e.g. a C 6-20  aliphatic or cycloaliphatic hydrocarbon or a C 6-30  hydrocarbon ester, ether or alcohol. In a preferred embodiment 2 alkyds are used, one containing less than and the other more than 50 wt. per cent of the polyalkylene glycol. Specific examples illustrate the dispersion of a simulated oil slick, a sea trial, extraction of naphtha and bitumen from tar sands and recovery of oil from steel plate.
