Abstract: 1464510 Preparation of N,N-dialkylxylylenediamines PFIZER Inc 7 Aug 1975 [19 Aug 1974] 33084/75 Heading C2C N,N - Dialkylxylylenediamines of the formula are obtained by reducing an α-[N,N-(dialkyl)- amino]tolunitrile of the formula wherein R<SP>1</SP> and R<SP>2</SP> are each (C 12  to C 20 ) alkyl groups, in an inert solvent, in the presence of a Raney Ni catalyst at a weight ratio of Raney Ni to tolunitrile in the range of 0À05 to 5À0 and NH 3  in a molar excess with respect to the tolunitrile, with H 2  at a pressure of 10 to 100 p.s.i.g., at a temperature of 0‹ to 50‹ C., until the reaction is complete. The preferred amount of NH 3  is 5 to 100 times the molar amount of the tolunitrile. The required product may be isolated as its dihydrochloride salt. Compounds of Formula II may be obtained by reacting an appropriate dialkylamine with α- bromotolunitrile in dimethylacetamide in the presence of K 2 CO 3 . The said dialkylamine may be obtained by refluxing an alkylamine with the appropriate alkanoic acid in a solvent and reducing the resulting N-alkylamide with sodium bis - (2 - methoxyethoxy)aluminium hydride in a solvent to give the required dialkylamine.

Title: Automatic control system having signal impulse integrator with variable time delay
Inventor: BRYS HARRY EUGENE
IPC: B21B37/16
Filed: 1963-08-21
Abstract: 1,059,725. Automatic control. ARMCO STEEL CORPORATION. Aug. 21, 1963, No.33089/63. Heading G3R. In a system for automatically controlling an operation performed on a moving web, strand or series of articles to maintain a physical property or condition of the material constant, electrical pulses dependent in sign on the sense of deviation of the property are integrated by a circuit having a single resistor and capacitor until sufficient capacitor voltage initiates correction and, simultaneously, discharges the capacitor. Integrator. In Fig. 2, D.C. pulses of one polarity or the other, according to the sense of deviation of a variable, are applied to terminals 40, 41 of an adjustable resistance-condenser integrating circuit 47, 46 so that, if a deviation persists in one sense to a sufficient degree, the voltage across the condenser is effective to operate one of two relays (not shown), to correct the variable by adjustment in the appropriate sense. At the same time, a relay 48 or 49 is operated to disconnect condenser 46 from the control system, e.g. by opening normally closed contacts 50, 51, and completing a discharge circuit for the condenser, e.g. by closing normally open contacts 57, 58. When the condenser voltage falls sufficiently to de-energize the relays, integration commences again. Thickness control. Integrators of the above type are incorporated in a three-stand four-high metal strip cold rolling mill. Electric signals from an inductive type thickness gauge between the first and second stands are filtered and applied through one integrator to control screw-down motors associated with the first stand to correct strip thickness. Means are provided to prevent this control for a time, after each operation of the screwdown motors, sufficient to permit the corrected strip to reach the gauge. This time is automatically adjusted in dependence on strip speed. Control is also prevented if the gauge is off the strip or if one screw-down motor only is operated to produce camber. Electric signals from an X-ray type thickness gauge after the third stand are applied through another integrator to control screw-down motors associated with the third stand to correct strip thickness in a similar manner. Tension control. Electric signals produced by a roll detecting strip tension control a motor driving the rolls of the third stand. Auxiliary features. There is provision for injecting test signals into the control system and for manual control. Strip footage and thickness indicators and recorders are provided.

Title: Safety means for protection against leakage currents
IPC: H02H3/33
Filed: 1960-09-29
Abstract: 962,658. Protective arrangements. R. MOSER, and J. MOREL. Sept. 29, 1960 [Oct. 2, 1959], No. 33448/60. Heading H2K. An earth-leakage protective arrangement includes a core-balance transformer 5 having primary windings 6, 7 connected in series with the phase, neutral and earth conductors, the winding 7 in series with the earth conductor T having a number of turns different from that of the other windings 6. In operation, should a person touch the unearthed frame of an apparatus 3 which has become defective, a small leakage current, e.g. 40 mA., causes sufficient unbalance between the windings 6 for the secondary winding 8 of the transformer to energize the release coil 9 of a switch 12 which opens. Should earth leakage occur on an apparatus 2 to which the earth conductor is connected, then the leakage current produces a flux in the core of the transformer due to the unbalance between the windings 6 and an opposing flux due to the leakage current in the winding 7 and the switch is released when the resultant of these fluxes induces sufficient current in the winding 8. Hence a higher leakage current to earth through the earth conductor is permitted before release of the switch occurs than would be the case when the leakage current does not flow through the conductor T. A resistance 16 connected between the neutral conductor N and the earthing conductor T, permits current to flow to earth through the appropriate winding 6 should the potential of the neutral rise above that of earth and so cause the release of the switch. The resistance 16 is also effective to produce the release of the switch should the earth resistance of the conductor T become too high and an earth fault occur on the apparatus 2.

In Figs. 1 and 2 is shown a portion of an approximately circular track 1 of a suitable size for a player to stand in a central position and describe a stroke with a golf stick'10. On one face of the track 1 is a cam track 2 mainly parallel with the edges of the track 1 but crossing from one edge to the other, as shown, at one portion of the track.
