Abstract: In a process for providing a color image which comprises imagewise exposing a multilayered light-sensitive photographic material comprising a support and a light-sensitive silver halide emulsion layer not having a coupler incorporated therein and thereafter developing said exposed photographic material with a coupler-containing color developer, the speed and color density of the image are improved by incorporating into the light-sensitive silver halide emulsion layer or the layer contiguous therewith oil particles of a high boiling solvent such as phthalate, phosphate, amide and alcohol type solvents.

Abstract: A method for identifying an article provided with a coded magnetic member comprising creating a detection zone by supplying an exciter coil with exciting alternating current, passing the article with the coded magnetic member through the detection zone to produce at least one signal from the coded magnetic member and detecting the derived signal using a detector coil to determine the code of the magnetic member. The magnetic member is provided with at least one of a plurality of elements made of magnetic alloys each having a different hysteresis loop and a code value is assigned to each type of alloy. The code value of each of the elements is decoded by measuring the phase shift of the signal derived using the detector coil relative to the phase of the exciting alternating current. This phase shift is indicative of the type of alloy and of the code value assigned thereto.

Abstract: A control keyboard for electric or electronic machines, with a first plate having a number of apertures, and keys mounted through these apertures; the keys have flanges of magnetic material on their lower portions to prevent the keys from slipping out. A second plate underneath the first plate has contacts cooperating with the key flanges. The first plate has an upper metal plate and a lower magnetic layer. The keys are movable between a first position when flanges are applied to the lower magnetic layer, apart from the contacts, and a second position where the flanges touch the contacts. The lower magnetic layer and the flanges return the keys from the second to the first position by magnetic attraction. An upper grid mounts the keyboard in a casing, with the upper metal plate between the lower magnetic layer and the upper grid. Each key has a body and a cap. A sheet of fluid-tight and resilient material may be clamped between the upper grid and the upper metal plate.

Abstract: An anti-skid brake control device and associated method in which the device includes a wheel cylinder having defined therein a first hydraulic chamber connected with a brake fluid line extending from the master cylinder and a second hydraulic chamber connected with a pressure controlling fluid circuit. As the brake fluid line is isolated from the pressure controlling circuit by the output member of the wheel cylinder, the brake system can operate effectively, though in a conventional manner, should oil leakage occur in the controlling circuit. On a four-wheeled vehicle, each pair of front or rear wheel cylinders can be served by a common arrangement of such pressure controlling circuit for anti-skid control.

Abstract: A control system for automatic operation of travelling objects through a power supply system without using any signal communication systems. Either a DC power source or three-phase AC power source is utilized as a power source. With the system employing a DC power source, three trolley wires are installed, one a negative and two positive. Each of the positive wires is divided and insulated into sections of a predetermined length; the positive feeding trolley wires in each section is always supplied with the DC power, and the power to the other positive feeding trolley wire is switched on and off depending on the movement of travelling objects. Each travelling object is supplied with power by the three trolley wires has a DC motor, and when one of the positive wires has no voltage, this is detected and the braking is effected. The travelling object entering a station is automatically decelerated and stopped.

Abstract: An induction furnace intended for melting a metal which is disposed in a crucible in an alternating magnetic field developed by an inductor enveloping this crucible. Induced in the metal is a current which heats the latter. Fixedly mounted intermediate the crucible and the inductor on the outer surface of the latter is a heat-resistant current-conducting screen made from a carbon material of not more than 1.5 mm thick. The screen envelops the entire inner surface of the inductor and is electrically connected to a signal system intended to indicate the degree of wear of the crucible wall. The signal system is set to a predetermined voltage at which the furnace is shut down to avoid an emergency situation.As the crucible walls wear out in the course of operation, the crucible resistance is therefore reduced, whereas the electrical potential in the crucible between the screen and metal is increased.When a preset voltage is attained, the signal system is actuated to discontinue the furnace operation.

The time correction reset signal resets the counter means for seconds, tens of seconds, minutes, and tens of minutes so that the output signal thereof becomes a signal for "O" display.

Abstract: A loading arrangement for obtaining an equally distributed pressure load in a cylinder stack included in a printing unit of an offset printing press, comprising a plurality of cylinders each having a cylindrical body portion and stub shafts at both ends, journalled in bearings. The arrangement includes axially short load rollers for producing a pressure load to the outermost cylinders of the stack. The rollers are located to act on portions between the bearings of the cylinders, and hence, the pressure load is transmitted directly to the body portions of the outermost cylinders. This minimizes the deflection of the cylinders.
