Abstract: A self-regulating oscillator circuit and method are disclosed. Specifically, a method is described whereby an oscillator having an active device is operated. The oscillator is operated by providing a current through the active device, as well as through a reference device connected in series with the active device of the oscillator. A reference voltage across the reference device is sampled, and a regulated voltage is generated by adding a predetermined voltage to the sampled reference voltage. Finally, the regulated voltage is applied to the active device of the oscillator. In one circuit embodiment, the oscillator as described includes a gallium arsenide FET structure which cooperates with a resonant structure to produce a reflection-type oscillator. In addition, a regulator circuit is described including an isolating op amp which samples the reference voltage from the active device of the oscillator and provides its output to a voltage source device. The voltage source device adds an additional fisted voltage to the sampled voltage and the additional voltage is connected through a pn junction to provide a regulated output voltage. The regulated output voltage is connected to the active device of the oscillator, thereby maintaining the voltage drop across the active device to improve oscillator performance.

Abstract: Rigid foam material, for example, expanded polystyrene foam, is drilled using a bit that forms an annular slit in the foam material and compresses the block temporarily around the slit. This frees the core for ready removal. The drill bit has a cutting ring at the leading end with an inside cutting edge and an annular bevel leading from the cutting edge to the outside surface of the cutting ring. The cutting ring is mounted on the leading end of a tube with an inside diameter greater than the inside diameter of the cutting ring in order to clear the core and an outside diameter less than the outside diameter of the cutting ring in order to clear the surrounding foam material.

Title: Flexible sign retention and tensioning frame assembly
Inventor: HOLLOWAY GRAHAM F
IPC: G09F15/00
Filed: 1994-06-28
Granted: 2001-05-01
Abstract: A retention and tensioning frame assembly is  used to  securely and tautly mount  a  flexible sign, such as an advertisement display panel, to the side of a truck or of the semi-trailer of a tractor trailer.  The frame assembly can be used to secure any flexible sheet-like panel to a flat  surface, e.g.  a billboard.  The frame assembly comprises  a series of frame  sections which define a  slightly open  longitudinal  cylinder  adapted  to  receive therein a peripheral bead of the sign.  The frame sections   are adapted to be fixedly mounted to a side wall of the semi-trailer or the like thereby securing  the  sign  to  the  side  wall.  Each  frame section defines at an outer edge thereof opposite its cylinder an inturned lip which can be engaged by a pulling device for outwardly pulling on the sign, one side at a time, for tautly tensioning the sign. The frame sections,  once engaged to the sign,  are normally loosely attached to the side wall, and then the  sign  is  tensioned  using  the  pulling  device before the frame sections are tightly secured to the side wall with the sign being taut.

The data bus 6 1, which is connected with one datapath element 1 1, can be connected with the other data buses 62 to 6N through an interconnection network 5, so that by activating one datapath element 1 1 only, data exchange can be made with all of the local memories 2 1 to 2N through the data buses 6 1 to 6N and the interconnection network 5. Thus, the multiple datapath elements can perform the parallel operations with being related with the multiple local memories: and a simple configuration is employed such that one datapath element can access to any one of the local memories.

Abstract: La scie circulaire comprend un disque porteur et une pluralité de dents de scie se fixant à l'horizontal sur les faces du disque en bordure de sa périphérie externe et s'étendant à intervalle régulier autour du disque porteur. Chacune des dents a la forme d'une plaque mince pourvue d'au moins deux pointes tranchantes disposées à égale distance de l'axe central de la dent. Chacune des dents est fixée et bloquée sur le disque de façon à ce qu'au moins une pointe tranchante s'avance en saillie de la bordure périphérique et de façon à ce qu'il lui soit impossible de tourner autour de son axe central. Cette scie circulaire a l'avantage de permettre de modifier facilement la position d'une ou plusieurs dents de scie en cas de bris d'une des pointes tranchantes. La position des dents peut être modifiée par simple démontage et rotation de la dent de scie autour de son axe central, de manière à ce qu'une autre de ses pointes tranchantes non brisée se trouve en saillie de la bordure périphérique. La dent est ensuite rebloquée et à ce moment l'opération de sciage peut se poursuivre. Cette scie avec des dents multi-pointes ajustables permet donc un remplacement rapide de ses dents endommagées et cela, à un coût raisonnable.
