Abstract: The invention relates to an arrangement for the easier inserting of pin bases into sockets, by means of closed-form guide profiles which are used simultaneously for coding, in order to prevent the installing of lamps into sockets unsuited therefor.

Abstract: The invention describes a method for the modulation of the light intensity of fluorescent lamps via the supply main by modification of the form and/or the amplitude of the power supply provided. An electronic control element, provided as a component of the logical circuit, temporarily blocks current flow after at least every second zero-crossing of the voltage, dependent upon time and/or voltage. Blocking of the current flow occurs only during the time period in which there is no flow of charging current for the downstream direct-current mains supply circuit. The advantage thus obtained is that the control pulses for the logical circuit do not influence the electric current flowing through the fluorescent lamps.

Abstract: The invention concerns a gas discharge lamp or vessel wherein at least part of the lamp is in the form of a spiral. The windings of the coils forming the spiral are tightly-spaced (less than 1 mm apart). In addition to providing high amounts of light, the compact packaging resulting from the design offers safety advantages in that the electrical contacts are located deep within the vessel interior. Thus, the opportunity of contacting live electrical contacts in the event of glass breakage is lessened.

Abstract: A fluorescent lamp wherein the replaceable gas discharge bulb assembly is equipped with parallel pins which are formed directly in the bulb assembly. Due to this modular construction, the bulbs can be used in a variety of applications.

Abstract: A gas discharge tube (e.g., a lighting tube) comprising two coiled segments is described. The geometry of the coiled segments is such that the angle of the tangent to the center line of the tube with respect to the tube's longitudinal axis gradually increases as one moves upward along the ascending coiled segment, and gradually decreases as one moves down the descending coiled segment.

Abstract: A method and device for controlling electric discharge lamps with electronic fluorescent lamp ballasts, using a bistable reverse switch system in the electric circuit in such manner that in turning the lamp on to a first switching condition, and after a short period of interruption of the electric circuit to the current supply of the lamp, the bistable reverse switch system acquires a second switching condition. It is thereby possible to reduce the lamp from a first level of brightness to a second lower level of brightness. It has the effect of a "dimmer" used with fluorescent lamps.

Abstract: A duplicating and ciphering device in which, in order to retain the privacy of the document to be transmitted, the individual units of the duplicating and ciphering device are constructed as a duplicating machine, and annexation possibilities for an electronic memory for storing the information taken from the scanner and for a coding mechanism for coding this information. Such device can be used as a duplicating machine as well as a ciphering device for coding information before entering it into a fax machine. It is also suited to again emit incoming, encoded information in clear text. A method for coding facsimile telecopies is included whereby in sending, the original is scanned and transmitted line by line and at the receiving end a similar copy true to the original is printed out. In order to prevent confidential information from falling into the wrong hands, the content of the digital transmitted information is coded.

Abstract: A process and equipment for safeguarding the operation of gambling machines with electronic cards in a manner that protects against counterfeiting and fraud. The microchip cards are numbered and a central computer stores at least the amount paid in for playing under the particular card number upon issuing the card. A card is inserted in a gambling machine, which has a read/write unit that compares the amount available for playing with the credit stored under the respective card number in the central computer before releasing the gambling machine for playing. Only if the two amounts match is the machine released for playing and the prevailing credit balance for the card is transmitted continuously during play to the central computer.

Abstract: An indicator used for monitoring whether or not a cooled or deep-frozen product has exceeded a preset critical temperature. The indicator includes a hollow shape which is symmetrically divided by separating walls. This structure allows the indicator fluids to be placed on a circular radius within the hollow shape. This design also exhibits a special centrifugal axis. This axis allows the fact that the products have reached the critical temperature to be disclosed in the following manner: the indicator fluids melt and move away from their resting place in the hollow shape. If the fluids are re-frozen, they can not return to their prior resting place because the fluids arrived at that original resting place due to centrifugation. Thus, departure from the fluids' centrifuged state gives notice that the products have reached their critical temperature.

Abstract: A process for the production of an indicator for monitoring the temperature of a cooled or deep-frozen product, such as packaged foodstuffs, pharmaceuticals and the like, is provided, which indicator shows that a predetermined critical temperature of the cooled or deep-frozen product has been exceeded. An easily applicable and economically made indicator is produced by casting a substance which is fluid or semifluid above the critical temperature into a specific geometrical shape and then cooling the substance below the critical temperature until it assumes a solid form. The critical temperature may in this connection lie above or below 0 degrees Centigrade.
