Title: Improvements in change speed gears
IPC: F16H3/36
Filed: 1955-11-29
Abstract: 809,032. Variable-speed gearing. SCHAFER, K. Nov. 29, 1955, No. 34108/55. Class 80 (2). In variable-speed gearing of the type in which a driving gear 4 is moved axially along its driving shaft 1 to engage selectively with one of a stepped cone of gears on a driven shaft 17 the gear 4 is operated by a fork 8 on a slide member 7 guided on rails 5, 6. The slide member 7 has a roll 10 engaging in the grooves 11 of a roller 12, each groove having two portions 11a of no lead and two inclined portions 16 so that a continuous groove along the roller 12 is formed. The roller 12 is adapted to be turned through 180 degrees and then stopped on each actuation of a control lever 65 to move the pinion from engagement with one gear of the driven cone to the next adjacent one. This operation is effected by the lever 65 moving through linkage 67, 69, 72 and forks 41 a coupling gear 31 axially of the shaft 40 of roller 12 into mesh with one or other of oppositely rotating pinions 34, 35 driven from oppositely rotating gears 25, 26 free on the shaft 40 which are in turn driven through trains of gears from a gear 18 of the shaft 17 of the cone of gears. The coupling gear 31 has diametrically opposite interrupted portions one of which in the neutral position of the coupling lies opposite the pinion 34 or 35 and allows the free movement of the coupling axially in one direction or the other. Initial rotation of the gear 31 before a toothed portion thereof is driven by a pinion 34 or 35 is effected by a catch 39 on gear 25 or 26 engaging a rose 38 of the gear on an engaging movement of the gear axially. After rotation of the roller 12 through 180 degrees during which the roll 10 passes from one groove portion of no lead through an inclined portion into another portion of no lead the gear 31 is disengaged automatically by a cam projection 45 on gear 25 or 26 engaging one of projections 38 on the gear 31. The last grooves of the roller 12 have portions connecting with the preceding grooves so that the slide 7 cannot be moved beyond positions at which the gear 4 engages the extreme gears of the cone. Spring pawls and rollers are adapted to engage notches on the roller 12 to position the roller accurately after each 180 degrees of movement and to prevent overrunning. The control linkage is interlocked with these pawls so that a gear shifting operation can only take place on completion of a movement of the control lever 65 and further movement of the control lever is prevented until the gear shift is completed.

The system operates to form from periodic impulses (i 9 ) periodic signals (Va) of longer duration to control the capactiive load A. In Fig. 1 which operates as a divide-by-two circuit for impulses (i 9 , Fig. 2, not shown) applied at E 9 , assuming C 35  and C 36  are discharged the first impulse (i 9 ) at Eg turns on T 32 , T 35  to charge the capacitive circuit A. The next impulse (i 10 ) at E 10  turns on T 34 , T 33  and T 36  to discharge C 35  and the capacitive circuit A. The next impulse (i 9 ) at Eg does not affect the output and the next impulse (i 10 ) at E 10  turns T 34  on and T 33  and T 36  off so that the next impulse (i 9 ) causes the capacitive circuit A to charge via T 35  and the above cycle is repeated. In a modification of this (Fig. 3, not shown) the inputs E 9  and E 10  are supplied with the same impulses so that the first impulse charges the capacitive circuit A and the second impulse discharges the capacitive circuit A. The circuits may be formed as integrated circuits. Specification 1,372,679 is referred to.

Title: Manufacture of n-oxyethyl-derivatives of 4-amino-1-oxybenzene
IPC: F16N21/04
Filed: 1927-12-29
Abstract: 290,997. I. G. Farbenindustrie Akt.- Ges. May 23, 1927, [Convention date]. Addition to 280,873. Mono- and di-N-oxyethyl derivatives of 4- amino-1-oxybenzene are obtained by condensing the latter with ethylene oxide at ordinary or raised temperature and pressure, advantageously in the presence of a diluent and/or a catalyst. Acids, alkalis and salts of mercury may be used as catalysts. In examples, the di-N-oxyethyl-4- amino-1-oxybenzene is produced by carrying out the reaction with an alkaline catalyst, e.g. calcium carbonate or aqueous caustic soda. In another example, ethylene oxide is passed into a suspension of 4-amino-1-oxybenzene in water containing concentrated sulphuric acid and mercuric acetate until the first traces of the dioxyethyl derivative are detected. The mono-N- oxyethyl derivative is worked up as sulphate by neutralizing with sodium carbonate, filtering, evaporating to dryness in vacuo and adding concentrated sulphuric acid to the solution of the residue in alcohol. According to a further example, a mixture of the mono- and di-N- oxyethyl derivatives is obtained by treating a suspension of the 4-amino-1-oxybenzene in water with ethylene oxide at elevated temperature. The less soluble di-N-oxyethyl derivative separates first in cooling the filtered reaction liquor.

Title: Improvements in pressure fluid mechanisms for oscillating vane motors
IPC: F15B15/12
Filed: 1956-11-20
Abstract: 793,033. Rotary engines. AKTIESELSKAPET FRYDENBO SLIP & MEK. VERKSTED. Nov. 20, 1956 [Nov. 20, 1956 [Nov. 21, 1955], No. 35445/56. Class 110 (2). In an oscillating vane type hydraulic motor resilient 0-section packings 14, 15, 17, 18, 21 and 22 are used to seal the gaps between the stator and the rotor 12 and its vanes 10, 11. At each point where a seal is made the packings are arranged in pairs with a space between them, thus creating a chamber 23. Working fluid from the side of the vane which has the higher pressure on it passes a non-return valve 28 or 29 and reaches chambers 23 via the narrow passages 24 suffering a slight pressure reduction due to the throttling effect in the passages. At the extreme positions of the vane the stem 31 or 32 contacts the stator and opens the valve in the low-pressure side of the vane, thus relieving the pressure in the working chamber. By varying either the diameter of the passages 24 leading to the end faces of the rotor or the distance between the packings 21 and 22 on the end faces of the rotor, differential end thrusts may be achieved to counter-balance external axial loading of the rotor shaft.
