Abstract: Abstract A coin operated vending machine comprises a housing having upright walls, a base, a top, and a partition between the base and top dividing the housing into an upper product bin and a lower cashbox.  The partition defines an aperture therethrough to provide communication between the bin and cashbox and has a spindle protruding upwardly from the central portion thereof. A dispensing wheel is provided having a hub with bearing means at the center thereof for engaging the spindle and supporting the wheel upon rotation thereof about the spindle, and having a rim with a plurality of gear teeth about the circumference of the bottom edge thereof.  A coin activated gear mechanism is positioned in an upright wall of the housing in the vicinity of the partition, said mechanism having a handle attached to one end of a shaft and a transmission gear attached to the other end thereof.  Structure is provided for locking a delivery chute in place thereby restricting access to the cashbox. Structure is positioned above the dispensing wheel at that portion of the partition defining the aperture therethrough for excluding all loose items of product from the aperture in the partition, thereby insuring that only items in containers are dispensed upon operation of the machine.  The door for the delivery chute activates a safety mechanism which locks the transmission gear upon opening the door.

Abstract: ABSTRACT OF THE DISCLOSURE        This invention relates to a method of manufacturing rotatable ignition files or flint wheels such as those found in lighters.  The method comprises cutting elongate wire stock of the desired gauge in blanks and applying a series of press operations to the blanks using punches and dies to champfer the peripheral edges of the blanks.  This provides axial mounting holes and hardens the respective surfaces of the blanks.  This method results in less wastage of material and provides more uniform blanks.          The outer hardened layer on the wheel has better hardness properties, tensile strength and yield point and an improved wear resistance when compared to those of the prior art.

Abstract: ABSTRACT OF THE DISCLOSURE          A touch-sensitive key has a radiation-propagating prism or plate between a radiation source and a radiation detector. Radiation is scattered from a top surface of the prism or plate so as to reach and activate the detector through a side surface when the top surface is touched.  External radiation is free to enter the prism or plate and to leave through the side surface but this radiation is not capable of actuating the detector.  In one embodiment the detector is spaced from the side surface so that it cannot be reached by external radiation. In an alternative embodiment external radiation is subjected to multiple reflections within  the prism or plate and at each reflection part of the ratiation is transmitted through the pertaining surface to be absorbed in a substrate layer.

Abstract: Abstract The invention concerns a device for processing fish heads, especially for separating pieces suitable for human consumption, especially the cheeks, the chin flesh and the tongue resp. the gills, the latter being unsuitable for human nutrition.  The device is characterised in that a feeding trough receiving the fish head in swimming position is provided, a feeler being arranged at its end toactivate a conveyor which engages the fish head behind the lower jaw while opening the pharynx and pushes it on the spear-shaped end of a guide.  In the region of the guide the fish head is taken over by a conveyor extending over and along the guide and guided to a cutting device for separating the fish head, the gills being ripped out beforehand by spreading flaps arranged on the flanks of the guide.

Abstract: ABSTRACT OF THE DISCLOSURE    The invention relates to a hearing aid with a housing insertable into the auditory canal, wherein the housing contains at least a microphone, an amplifier, an earpiece and a power source.  In instruments of this kind it has turned out to be desirable to have, in addition to the usual volume control, an additional control by means of which the way the incoming sound signals are influenced by the amplifier (i.e. its characteristic) can be adapted to individual hearing impairments.  For this purpose the invention provides in the space housing the battery a pitch control in such a manner that its actuating member can be operated at least when the power source is removed from the instrument.  This makes it possible to reduce the space requirement for the pitch control so that even hearing aids insertable into the auditory canal can contain such an additional control.

Abstract: ABSTRACT OF THE DISCLOSURE The activity of the microbial insecticide, Bacillus thuringiensis (B.t.) Berliner has been found to be synergistically enhanced by the addition of unsaturated 18-carbon fatty acids. A synergistic effect with respect to increased larval mortality of the western spruce budworm, Choristoneura occidentalis Freeman was obtained in the C18 unsaturated fatty acid/B.t. treatments. Enhanced mortality was also observed in C18 fatty acid/B.t. treatments of the larval form of the silverspotted tiger moth, Halisidota argentata Packard. The increased insecticidal activity of the entomogenous bacteria, Bacillus thuringiensis (B.t.) Berliner by the addition of unsaturat-ed 18-carbon fatty acids represents a significant breakthrough for the expanded use of this microbial insecticide.
