Abstract: A local network call handling device is configured to establish multiple concurrent call sessions between local network end devices and an external network. When a prioritized end device attempts to establish a call session, the call handling device may initially determine if a first call session identifier is available. If so, the call session can be established using that first identifier. If the first identifier is in use for a call session of another end device, the call handling device may either use a different call session identifier for the prioritized end device session or may drop a pre-existing call session to free an identifier for use in connection with the prioritized end device.

Abstract: A wallet is constructed so when a credit or identification card is withdrawn from a card pocket and is not replaced, the owner viewing the card pocket is reminded of the fact that the card has not been replaced. The pocket has a front wall with a top edge and a rear wall that extends higher than the front wall top edge. A prompt of highly attention-getting material such as a holographic type light-reflecting strip, is attached to the rear wall to lie above the top edge of the front wall. When a card lies in the pocket, the top portion of the card covers the attention-getting prompt, but when a card is not present the attention-getting prompt attracts the owner's attention to remind him that the card has not been replaced.

Abstract: A system and method for deadweight calibrating a dynamometer having an output indicative of a motor action is provided. A weight cart has a base and defines a working axis non-parallel to the base. A hanger arm is adjustably mounted to the weight cart for movement relative to the weight cart along the working axis. The hanger arm has a loading surface for holding a plurality of calibration weights. The hanger arm loading surface is configured with respect to a loading surface on a dynamometer calibration arm such that movement of the hanger arm incrementally places the calibration weight on the calibration arm loading surface to simulate motor action and allow calibration of the dynamometer.

Abstract: A new 35 mm motion picture film is described which minimizes the amount of film stock that is used, and which facilitates industry acceptance by assuring at least present image quality. The new motion picture format (12) has film frames (20) of a size (22, 24) that is slightly greater than that (J, K) of the mask aperture (H) of the current Wide Screen Academy Format. However, the film frames are spaced by a distance (26) that is more than two but less than three times a standard perforation spacing distance (E). The film stock can be different from current film stock, with a perforation spacing distance (48, 68) that results in 2 or 3 perforations per frame.

Abstract: Systems are described for precisely positioning motion picture film frames at a camera film gate by the use of registration pins that project into film perforations, where the film frames are spaced by 2.5 perforations instead of the standard 4 perforations. In one system, the registration mechanism includes two sets of registration pins which project into film frames as the film is advanced in steps of 2.5 perforations. In another system, additional holes are punched into the standard film stock, so there are holes or perforations located at 2.5 perforation spacings along the length of the film, so only one set of registration pins is required for precision registration of film frames spaced by 2.5 perforations.

Abstract: A method is described for producing Cinemascope-type motion picture images that have a large aspect ratio (e.g. 2.35 to 1), which enables their high quality projection using moderately priced projection lenses, which produces a steadier projected image, and which increases the life of the release print while reducing its cost. A scene is photographed in the prior art manner, using an anamorphic lens to produce 50% horizontally compressed anamorphic camera film frame images (aspect ratio of about 1.175 to 1). During processing to produce a release print, another anamorphic lens is used to produce 36.5% vertically compressed anamorphic release print film frame images (aspect ratio of 1.85 to 1) of the camera film images. An anamorphic projection lens is used in a motion picture theater to horizontally expand the projected images by about 27% (to an aspect ratio of 2.35 to 1).

Abstract: Systems are described for precisely positioning motion picture film frames at a camera film gate by the use of registration pins that project into film perforations, where the film frames are spaced by 2.5 perforation spacings, or perf spacings instead of the standard 4 perforations. In one system, the film is advanced a first time in steps of 5 perf spacings each to photograph alternate perf spacings film frames, (that are spaced by 2.5 perf spacings) perf spacings with the film gate mask being offset by 0.5 during a second pass when the film is advanced in steps of 5 perf. spacings each. In another system, the registration mechanism includes two sets of registration pins which are alternately projected into alternate film frames as the film is advanced in steps of 2.5 perf spacings. In another system, additional holes are punched into the standard film stock, so there are holes or perforations located at 2.5 perf. spacings along the length of the film.

Abstract: A new 35 mm motion picture film is described which maximizes usage of film stock, and which facilitates acceptance by motion picture theater owners. Acceptance is facilitated by minimizing the cost for projector head conversion and by assuring at least present image quality. The new motion picture format (12, FIG. 4) has film frames (20) of substantially the same size (22, 24) as the mask aperture (H) of the current Wide Screen Academy Format, and uses the same size and spacing of sprocket holes, or film perforations. However, the film frames are spaced apart by a distance (26) that is a noninteger number of perforations, with the spacing being 2.5 perforations in a preferred format (12). A current projector head is converted for showing the new format, by providing new sprocket wheels (14, FIG. 5) with ten teeth, that mount on the same shafts of the projector head as current sprocket wheels that have sixteen teeth.

Abstract: A convertible sprocket for film and like media accommodates different media formats. The sprocket includes a first sprocket wheel support and a first sprocket wheel having a first dimension and supported by the sprocket wheel support. A second sprocket wheel support is co-axial with the first sprocket wheel support. A second sprocket wheel having a second dimension different from the first dimension is supported by the second sprocket wheel support. The second sprocket wheel is axially movable relative to the first sprocket wheel support so that the first sprocket wheel engages the medium when the second sprocket wheel is in a first position relative to the first sprocket support. The second sprocket wheel engages the medium when the second sprocket wheel is in a second position relative to the first sprocket support. The convertible sprocket has a plurality of axially spaced apart sprocket wheel wherein at least two of the sprocket wheels have different diameters.

Abstract: A circular projection system using segmented trapezoidal screens arranged in a continuous arcuate array about a central vertical axis. The top of each screen is tilted downward. Each screen is illuminated by a projector which is mounted above and behind the screen which opposes it. The image from each projector is also angled downward.For an eight-screen system, each screen is tilted by approximately 8.degree.. For a nine-screen system, each is tilted by approximately 7.degree.. For maximum linearity, the ratio of the distance between the projector lens and the top of the screen on which it projects to the width of the top of said screen is substantially equal to the ratio of the distance between the projector lens and the bottom of said screen to the width of the bottom of said screen.

Abstract: An apparatus for heating water, especially a hot-water boiler. The apparatus has a combustion chamber and two or more heat exchangers that are disposed one above the other. The heat exchanger disposed in the bottom of the apparatus is associated with a condensation chamber. In order to be able to operate this heat exchanger without water, and to be able to raise the efficiency of the apparatus as a whole, the heat exchanger of the condensation chamber is provided with a fresh air inlet and a fresh air outlet. Air is conveyed through this heat exchanger, whereupon it is heated up. This warmed air is supplied to the burner of the apparatus.
