Abstract: The present invention provides means for the improved support and positioning of a core within a shell mold for casting gas turbine engine blades and vanes with cooling air passages therein. Disclosed is a tapered core/shell lock which is formed integral with the core main body and is used to anchor the core main body to the shell mold. The tapered core/shell lock includes notches which, in conjunction with protrusions from the shell mold, prevent axial slip of the core main body. In addition, the core/shell lock of the present invention provides a tapered core print area which is much larger, and extends further into the shell mold, than the conventional "T" bar core/shell lock. By increasing the axial length of the core print area, shifting at the tip of the core main body is reduced, while tapering of the core print eliminates the need to lacquer slip the end of the core/shell lock, eliminating additional sources of core shift.

Abstract: 2.1 In the case of conventional small-bottle forming machines, a single formfinger is assigned to the forming rollers, which form the mouth of the bottle. Such a formfinger is subject to a high degree of wear, causing the mouth profile of a bottle to vary during the course of a series. With the novel method and the novel formfinger, it is intended to reduce the wear to a minimum, so that better production tolerances are possible for the formed mouth. 
<??>2.2 This is achieved by either assigning each glass tube of a bottle-forming machine its own formfinger or giving the formfinger a certain amount of play or producing the formfinger with lateral clearances, maintaining a ratio between cross-sectional area and circle-segment area of the formfinger of >/= 0.55 x r. 
<??>2.3 These formfingers are used in all bottle-forming machines in which a multiplicity of glass tubes are used in a cycle to produce small bottles progressively by rolling and melting pieces of tube.

Abstract: 2.1 It should be possible to receive the MFC signals from both directions of transmission by means of a single multi-frequency code receiver. In addition, it should be ensured that the receiver also correctly detects an MFC signal when a valid frequency combination of the other direction of transmission in each case is wrongly present. Other types of disturbances should be masked out and it should be possible quickly to detect the end of signal. 2.2 The digital bandpass filters designed for particular frequencies are connected in parallel with a further common auxiliary digital filter covering the entire MFC frequency band. This filter responds quickly to signal changes and accelerates the detection of the end of the signal. It also provides for noise suppression. The bandpass filter and the common auxiliary filter are switched to different frequency groups as a function of the direction of the allocation of a connection in that a set of filter coefficients associated in each case is used for digital frequency evaluation. The common auxiliary filter in this arrangement acts either as a high-pass or as a low-pass filter. 2.3 Only a single receiver is needed for both directions of transmission, which must only contain the simple number of frequency-selective elements in order to detect the MFC-R2 signals. The arrangement of an auxiliary filter provided for masking out interfering frequencies is such that only those frequencies which can be actually considered as interference can prevent a detection of signals. <IMAGE>

Abstract: The invention relates to a method for reading and identifying information represented by signs (image), in particular bar codes, in a two- or three-dimensional field using a video camera (1) and a binary processor (3) which generates a binary signal (BIN) from the video signal of the image. The video signal (f(t)) is twice differentiated on a time basis and switching edges are derived from the zero values of the second derivation (f''(t)) which are further processed only if the amount of the video signal of the first derivation (f'(t)) exceeds a predefinable threshold (A-A'). The sampling frequency of the binary video signal is greater than or equal to the sampling frequency of the video camera. Within a local environment, the autocorrelation function is calculated for a plurality of discrete points of the binary signal and a local maximum and/or the associated direction vector is determined from the autocorrelation values obtained, from which the structure of a bar code, for example, can be ascertained. <IMAGE>

Abstract: Errorless switching of digital signals from a service channel to an alternate channel is achieved even when the signals have a format in which the payload can float within the frame or in which the overhead bytes of the service channel may be different from the overhead bytes of the alternate channel. A preprovisioned delay is provided on the service channel. The amount of delay between corresponding frames containing the same payloads in the digital signals being transported in each channel is measured and added on the alternate channel, thus aligning the channels. The payloads within corresponding frames in the digital signals being transported in each channel are aligned by passing a pointer value indicating the start of the payload of the signal being transported in the service channel to the alternate channel and shifting the payload of the signal being transported in the alternate channel in accordance with the passed pointer value. Once the two signals are frame and payload aligned, a switch is made from the signal transported on the service channel to the signal transported on the alternate channel.

Title: High power factor power supply
Inventor: STEIGERWALD ROBERT LOUIS
IPC: H02M1/00
Filed: 1992-02-06
Abstract: An off-line switching power supply includes an ac rectifier and a dual-output switching converter having one output coupled between the ac rectifier and the input to the dual-output converter in order to provide a high power factor, the other output of the dual-output switching converter providing a dc voltage as the power supply output. The outputs of the dual-output converter are fully decoupled so as to allow independent control of the ac input current and the power supply output voltage. In a preferred embodiment, a full-wave ac rectifier bridge is coupled in series with the second output of the power converter via an input resonant boosting converter. A full-bridge dc-to-ac converter is coupled between the dc link and ground for providing an ac signal to excite the boosting converter and for providing another ac voltage through a transformer to an output rectifier to generate a regulated dc output voltage. The amplitude of the regulated output voltage is controlled by pulse width modulation, while active frequency control of the boosting converter is provided to control the amplitude of the ac input current. Alternatively, frequency control of the boosting converter is passive, i.e., depends on the gain characteristics of the boosting converter resonant circuit. As a result of the complete decoupling of the input boosting converter and the power supply output voltage, the off-line switching power supply is capable of drawing high quality current waveforms from the ac source while producing a regulated dc output voltage with fast transient response.
