Abstract: This lock comprises handling members which may be actuated according to a code, and a rack which may be displaced after actuating the actuating members controlled according to the code. Each actuating member cooperates with an insertion part which comprises at least a recess and which may be brought into two different positions. The insertion parts arranged according to the code prevent, in their start position, the displacement of the rack and, in their working position given by the cooperating actuating member, they allow the displacement of the rack owing to their recess or recesses. The insertion parts, which are not arranged according to the code, operate inversely. Thus, there is no resiliency difference between the coded and non coded actuating members and it is not possible to determine the code by groping.

Title: Process for impregnating organic fibers
IPC: D06M101/16
Filed: 1982-02-10
Granted: 1984-07-25
Abstract: Organic fibers are impregnated with an aqueous emulsion comprising (1) an organopolysiloxane containing diorganosiloxane units in which both organic radicals are monovalent hydrocarbon radicals, and further contains at least two monovalent SiC-bonded organic radicals with a basic nitrogen atom per molecule in which the SiC-bonded organic radicals with a basic nitrogen are present in monoorganosiloxane units, (2) an organopolysiloxane having at least 3 Si-bonded hydrogen atoms per molecule, (3) a catalyst for the condensation of Si-bonded condensable groups (4) emulsifiers, and (5) a diorganopolysiloxane containing an Si-bonded hydroxyl group in each of its terminal units and whose radicals are free of the basic nitrogen atom. If it is desired to impart hydrophobic properties to the impregnated organic fibers, then it is essential that (6) a trimethylsiloxy end-blocked diorganopolysiloxane be added to the aqueous emulsion. Moreover, as the amount of trimethylsiloxy end-blocked diorganopolysiloxane (6) is increased in the emulsion, the hydrophobic properties of the impregnated fibers increases.

Abstract: Ventilating unit comprising a housing to the front of which is fitted, preferably pivotably, a cover-flap. The front of the housing comprises a wall that closes off the interior in which a fan is arranged. Known ventilating units of this kind contain, inside, a plurality of components, more particularly a fan, insulating material, an actuator, etc. These components have hitherto been secured to the housing, and to each other, by means of screws or other attachment-elements, resulting in relatively high material and assembly costs. Furthermore, cleaning of the ventilating ducts, involving opening-up the unit, has been possible only by using trained personnel. In order to overcome this problem it is therefore suggested that the wall be built as an inspection-flap which is hinged to the front edge of the housing and is provided with means for locking it to the housing. In this connection the fan housing is designed, or bears against the said inspection-flap, in such a manner that when the latter is locked, the fan-housing is also locked in the housing. Finally, at least one retaining wall is preferably provided inside and this, together with the inspection-flap, produces a ventilating unit with adequate stability.

Abstract: Coin validation apparatus may be associated with a coin freed mechanism on coin receiving machines or form part of a coin sorting apparatus to check that coins are valid coins and not counterfeit. Recently, it has become particularly convenient to use the interaction between a coin and an alternating magnetic field to gauge various parameters of the coin thereby to determine if the coin is valid. In such a method the frequency of a feedback oscillator having a tuned electrical coil in its feedback loop is monitored when a coin is present adjacent the coil, the frequency is then monitored when a phase shift or time delay network is also included in its feedback loop, two parameter signals characteristic of the effect of the coin on both the inductance and the loss factor of the coil, are derived from these maintained frequencies and the two parameter signals are compared with reference values to determine if the coin is valid.

Abstract: A late mask programming process is provided for factory programmed ROMs or logic circuitry. MOS transistors functioning as ROM cells or in logic circuitry are fabricated by a standard MOS Process. Then, a thin stop layer of silicon nitride is provided over the transistors followed by a layer of silicon dioxide. Programming is accomplished by applying a program mask and etching through the layers overlying the gate regions of selected transistors down to the silicon nitride stop layer. The silicon nitride stop layer prevents overetching and shorting of the gates. Then, ions are implanted underneath the gates of the selected MOS transistors to alter their threshold so, for example, as ROM cells they signify a different state than those cells whose transistor gates are not implanted with ions. The silicon nitride layer serves to stop the etch solution but permits the ions to pass through, penetrate the substrate and raise the thresholds of the selected transistors. The silicon dioxide layer stops the ions from being implanted into the nonselected transistors.
