Abstract: A B S T R A C T     The invention relates to a thermically controlled electrical switching element in the form of  a temperature regulator or a temperature limiter.  On a socket are arranged, in parallel orientation, a bimetallic spring plate, and a steel plate deflectable to both sides. The bimetallic spring plate is attached at its periphery in such a way that centrally, above a transition temperature, it can deflect in a first direction, and below a reverse transition temperature, it can deflect in a second, opposite direction.  The steel plate attached at the rim together with the bimetallic spring plate, upon deflection of the spring plate, is also displaced in the first direction, and thereby, by means of a control element bearing upon its center, opens a switch contact interrupting the current flow to an electrical heating element.  In order to enable manual opening and closing of the switch contact pair within the switching element, in a simple manner, a control arm is placed in the rim area of the steel plate, whose control end is rigidly attached to the rim area of the steel plate, and whose actuating end either constitutes a manually operable push button, or is connected to such a push button.

Abstract: TITLE               LAUNCHER                        INVENTOR                         John LAVOIE                          ABSTRACT           A novel launching device to launch an aerodynamic disc toy discloses the use of a track that traces out the locci of points of a semicircle and then transforms  along a margin thereof. coincident with the semicircle, a tangential extension.  The diameter of semicircle of the locci of points is coincident with the diameter of the aerodynamic disc so that the disc is captured therein.          By horizontally swinging the launcher with the disc in the track, the launcher moves the disc from its semicircular abutment therewith to run along the straight track and thus to commence to spin thereby imparting to the disc both momentum and spin whereby aerodynamic flight ensues as soon as it is released.

Abstract: ABSTRACT OF THE DISCLOSURE       APPARATUS AND METHOD FOR ROLLING BEAD RINGS         Upper and lower rollers have grooves for a bead ring having  a  clamp area  portion  produced  by  a  bead winding machine.   The bead ring is placed in the groove of the lower roller with the beginning of the clamp area portion in position for pressing by lowering of the upper roller so that the bead ring is engaged by the groove in the upper roller.  The rollers are oscillated between the pressing position at the beginning of the clamping area and the end of the clamping area to roll the top, bottom and sides of the clamping area portion during the move-ment of the bead ring.  The pressure on the bead ring is released  by  raising  the  upper  roller  at  the  initial pressing position at the beginning of the clamping area so that the bead ring may be removed with the same orien-tation it had when it was placed in the groove.

Abstract: Abstract A contact pin for a printed circuit board compri-ses a mounting portion for mounting the contact pin in a hole in the printed circuit board. The mounting portion com-prises three legs extending in the longitudinal direction of the contact pin, at least the outer legs joining a solid contact pin portion at both ends. As seen in cross section, the centre leg is bent radially outwardly and lies with its inwardly directed part between the outer legs. Both outer legs are mainly twisted to a position in which these outer legs extend obliquely outwardly from the centre leg, as seen in cross section. The centre leg is displaced radially out-wardly with respect to the longitudinal axis of the con-tact pin a constant distance substantially along its whole length. As seen in cross section, the centre of the circle touching the outer side of the three legs, lies at a distan-ce from the longitudinal axis of the contact pin in a direc-tion redially opposite from the centre leg.

Abstract: ANSWER DETECTION METHOD AND APPARATUS FOR COIN TELEPHONE SETS     Abstract A coin operated telephone station is provided with apparatus for detecting when a called party has answered a call (initiated at the coin operated telephone station) by the measurement of incoming signal energy on the telephone line. The apparatus includes hardware and software that cooperate in providing efficient and reliable detection of called party answer for the purpose of accurately charging telephone users.          A microprocessor samples the output from each of three specialized energy detectors every 20 milliseconds to determine whether called party answer has occurred.  The energy detectors include: (1) call progress tones in the frequency band 200-700 Hz approximately; (2) special information tones; and (3) broadband energy in the frequency band above 200 Hz. Additionally, the time duration of the call progress tones and the quiet intervals between them are measured and used in the answer detection process. Signal energy from the calling party in the 200-700 Hz frequency band is filtered from the transmitting path by a 1200 HZ high-pass filter until called party answer occurs. Such filtering precludes a user from interfering with the detection process while permitting a limited amount of information to be transmitted in the event that the answer detector is slow to operate.

Abstract: METHOD OF FABRICATING A JUNCTION      FIELD EFFECT TRANSISTOR            ABSTRACT      Method of fabricating a junction field effect transistor, specifically a static induction transistor, which may be of GaAs.  Elongated N-type source regions are formed in an N-type epitaxial layer of semiconductor material grown on a substrate.  A tri-level mask is formed having elongated openings exposing portions o the epitaxial layer intermediate between the source regions.  The openings are wider at the bottom than at the  top.   P-type  gate  regions  are  formed  by ion-implanting P-type doping material through the mask openings.  Silicon dioxide is deposited through the openings  by  angle  evaporation  to  form generally trapezoidal-shaped temporary gate members over the gate regions.  The tri-level mask is removed, a layer of silicon nitride is deposited, and a layer of masking material is deposited.  Some of the masking material is removed; then the temporary gate members and silicon nitride immediately adjacent thereto are removed.  Metal for making ohmic contact to the P-type gate regions is deposited through the resulting openings.  The remaining masking material is removed, openings are formed in the silicon nitride over the N-type source regions, and metal for making ohmic contact to the N-type source regions is deposited in the openings.

Abstract: An internal impedance dependent amplifier has an amplification which is determined by the impedance at a given point in the amplifier. A p-i-n diode 42 is connected to the predetermined point 26. The p-i-n diode 42 is powered by a current Ip in the flow direction, which current constitutes the precise amplification control signal for the amplifier. In a preferred embodiment the p-i-n diode 42 is driven by an operations amplifier 56 in such a way that the impedance connected to the given point in the amplifier in this way is temperature dependent. As the p-i-n diode has an impedance expressed by log R = A + B log Ip, where R is the impedance of the p-i-n diode, Ip is the current in the flow direction and A and B are constants which are different for each p-i-n diode, the voltage Vc which is applied to the operations amplifier 56 which drives the p- i-n diode 42, is linear in relation to the impedance of the p-i-n diode 42 and thereby in relation to the voltage amplification in the impedance controlled amplifier to which the p-i-n diode is connected. This characteristic of the amplification in the amplifier makes it possible to cascade connect amplifiers A1 ... A11 and retain the same impedance ratio as expressed above for a cascade connection of amplifiers. The amplification in dB for the cascade connected amplifiers is thus log-linear in relation to a common control voltage, which is applied to each individual amplifier in the cascade connection. <IMAGE>
