Abstract: 893,850. Cutting wood. MULLER, C-H. April 6, 1960 [April 17, 1959], No. 12144/60. Class 145. Veneers peeled from a tree trunk by a peeling machine 1 are transported to an elevated treating machine 3, e.g. a shearing machine, by raising the loaded veneer rollers 11 out of the winding position in front of the peeling machine to a position in a magazine 2 from which they can be driven in the magazine into a position for unwinding of the veneer for feed to the machine 3, the empty roll 11 being then moved vertically to another track in the magazine for return to its original winding position. The magazine 2 is formed by two gantry uprights 4 and 5 connected by rails 6, 7 and provided with hoists 9, 10. The loaded rollers 11 are raised by a hoist 9 to the rail 7, and then rolled along this rail and raised by a hoist 10 to the unwinding position, the empty rolls returning along the rail 6 to be lowered by the hoist 9 to its original position. Alternatively, the cycle may be reversed, the loaded rollers traversing the rail 6 and the empty rollers returning along the rail 7. The upright 5 is carried on an underframe 8 which also carries the machine 3, in the form of an automatic shears, into which the veneer band B is fed from the loaded rollers. the first veneer peelings as they are ejected from the peeling machine are fed along a pivoted transfer platform 14 to trucks 12 which travel on rails 15 to a platform 16 arranged to be gradually raised for transfer of the veneers to a machine 13, the empty trucks then being returned along a track 17 and brought to the loading position down a hinged section of the track 18. In the main girders of the underframe 8 an additional roller track may be provided for veneer strips which can be conveyed on such a track, the ends 8b, 8c of the tracks forming transfer platforms to allow continuity between the machines and the track.

Abstract: The invention comprises pigment dyes of the general formula <FORM:1019000/C4-C5/1> in which Me represents a sodium or barium ion and n represents the integer 1 or 2 corresponding to the valency of the metal Me.  The pigments are prepared by diazotizing 3-nitro-4-amino-benzene sulphonic acid and coupling under neutral or weakly acid conditions with 1-acetoacetylamino - 2:4 - dichlorobenzene under neutral or weakly acid conditions and converting the product to the sodium or barium salt by addition of a water-soluble sodium or barium salt at about 20 DEG  to 100 DEG  C. The barium compound may also be obtained by treating the sodium salt with a water soluble barium salt.  The pigments may be employed to colour polyvinyl chloride.  Examples are furnished.

Abstract: 1461259 Supporting open-end spinning rotors PLATT SACO LOWELL Ltd 13 March 1974 [14 March 1973] 12189/73 Heading DID In an open-end spinning unit the rotor 31 is carried by a shaft 13 supported in gas bearings 11 and 12; between the bearings 11 and 12 is a thrust bearing 33 whose thrust surfaces 35, 37 are separated by the generation of a film of pressurised gas therebetween. The shaft 13 carries the rotor 17 of an electric motor and the thrust bearing may be disposed at either end of the same. The pressurised gas film may be generated by spiral grooves on either of the thrust surfaces and/or by a positive feed of gas e.g. through inlet 43. This gas supply also pressurises the housing 2 which causes a force tending to close the gap between the thrust surfaces 35, 37 by virtue of the additional area for the pressure to act on afforded by the free end of shaft 13. Gas bearings 11, 12 may be aerodynamic or aerostatic and the bearing bushes 15 are resiliently mounted in "O" rings 16 as is the fixed part 40 of the thrust bearing in "O" ring 39. A second gas thrust bearing can be arranged at the end of the motor rotor 17 remote from the spinning rotor 31, Fig. 4 (not shown), to locate the shaft in the opposite direction from bearing 33 and is fed by gas leaking from bearing 12 which in this case would be aerostatic.

Title: Improvements in and relating to gyroscopic apparatus
IPC: G01C19/00
Filed: 1942-09-04
Abstract: 559,895. Gyroscopic apparatus. ZARDECKI. J. Sept. 4. 1942, No. 12537. [Class 97 (iii)] In a gyroscopic apparatus for containing a constant direction in space or for he stabilization of other bodies, two rotors are mounted in a gimbal ring so that their axes are unidirectional and are so interconnected and driven that under  the action of an external force each aectom has a different precession speed, the interconnection  between the rotors being such that the rotor with  greater prescession speed imposes this on the other rotor to set up a second precession therein  in order to eliminate the first-mentioned precession in each rotor. As show in Fig. 1 the rotor 2 is freely mounted on the spindle of the rotor 1 within a gimbal ring 5 and is driven by an air jet 23 at twice the speed of the rotor 1. In operation, when an external force is applied, for example by attempting to turn the frame 5 about its bearings 7, the precession of the rotor 1 accelerates the precession of the rotor 2 and imparts to it a second precession which balances the applied force to set up a condition of equilibrium and arrest the precession of both rotors. In a modification, Fig. 3, the two rotors are tiltably mounted in bearings 14, 16 within the limits imposed by a thrust bearing 18, and are united by a common bearing 15 and cardan couplings 17 so that they rotate together under the action of a single air jet 25. When the spin axes of the rotors move out of alignment the gravity effects of the two masses set up differential moments which restore the axes to the vertical position. The arrangements shown in Figs. 1 and 3 may be combined as shown in Fig. 5.
