Abstract: A film cassette (1) is disclosed wherein a film spool (5) is rotatable within the cassette shell (3), a convoluted film roll (33) whose outermost convolution (35) is a film leader (35) is coiled about the spool, a pair of film constraining flanges (41, 43) are coaxially arranged on the spool to radially confine the film leader to prevent the leader from substantially contacting an interior wall (57) of the cassette shell, and a film stripper-guide (67) is received between a leading end (37) of the film leader and the next-inward convolution (39) of the film roll succeeding the leader to remove the leader from the flanges and guide it through a film passageway (25) to the exterior of the cassette shell responsive to rotation of the spool in a film unwinding direction. According to the invention, the film leader (35) and at least one of the constraining flanges (41, 43) include mutual engagement means (59, 51 min ) for maintaining the leading end (37) of the leader spaced at least a minimum radial distance (D) from the next-inward convolution (39) sufficient to locate the leading end within range of the stripper-guide (67) to ensure that the leading end will be advanced over the stripper-guide responsive to rotation of the spool (5) in the film unwinding direction, whereby the leading end is prevented from being advanced between the stripper-guide and the next-inward convolution.

Abstract: The closure is made of plastic in two parts. A top part (2) comprises an internal thread and a continuous outer surface (207) and an axial outer cylindrical portion (210) and, above the latter, a valve tube (209) which is held by means of a conical transition part (208). A bottom part (1) comprises an external thread (101) and a continuous outer surface (107) and an axial inner cylindrical portion (110) with, at its upper end (112), a sealing bead (111) facing the outer cylindrical portion (210) and, above said sealing bead, a valve pin (109) which is held by means of connecting webs (108). By rotating the top part (2) relative to the bottom part (1), the top part (2) is offset axially relative to the bottom part (1). A sealing part (113) is moulded axially onto the upper end of the valve pin (109). When the closure is screwed completely closed, the sealing part (113) fills the upper opening (206) of the top part (2). Its upper end (114) is flush with or projects over the top part (2) and the valve pin (109) is enclosed by the valve tube (209). When the closure is screwed completely closed, the valve pin (109) is located outside the valve tube (209). A rib (115) on the bottom part (1) and a baffle (215) on the top part (2) interact to limit the rotation of the top part (2) relative to the bottom part (1) by striking against one another to an angle of rotation of less than one complete revolution.

Abstract: A dust exhauster is described whose electric motor is designed as a commutatorless dc motor. The electrical and electronic components of the dust exhauster are positioned according to the invention within the motor cooling air intake channel. Consequently, they are directly cooled by the stream of cooling air, resulting in a substantially extended service life for these components. Furthermore, the motor with its components is relatively small in design.

Abstract: A portable exercise device which provides the benefits of working out with free weights. Adjustable foot pads (14) on opposite sides of a central housing (12) accommodate different stance widths and retract to a compact storage position. Right and left reels (50) in the housing (12) receive cords (56) which extend through the foot pads (14) and carry special hand grips (76). Outward pulling on the cords is resisted by spring packs (110) having clock-type coil springs (114). The spring packs can be stacked on one another to vary the resistive force applied to the reels. The two resistance systems are independent of one another but are adjusted to the same initial tension by a common cable adjustment mechanism. Attachment of added components allows rowing exercises to be carried out.

The electronic seal comprises a seal band which can be anchored in a casing and a monitoring device with an opening sensor disposed in the casing, a clock generator, a counter, a memory and an operating voltage source. 
<??>Along with the time data relating to changes in the condition of the seal, further logistical data such as the starting time, time zone, place of origin, destination, country, owner, carrier, means of transportation etc. can be stored in the memory. The seal band is furthermore incorporated in the security loop which monitors the condition of the seal, for example by designing the seal band as an electric conductor via which electric monitoring signals are transmitted.

Abstract: A differential capacitive pickoff detector circuit for measuring the difference in spacing of a pair of differential pickoff capacitor plates (C1C2). Current sources (22,24) are provided for each output terminal of each of the pair of differential capacitors so that for each capacitor output terminal a current signal alternates between a first current level and a second current level at a predetermined carrier clock switching rate. The capacitors are varied to provide double-sideband, large carrier voltage signals across each of the capacitors. The average value of each of the alternating voltages and their amplitudes are automatically adjusted to predetermined levels. The two DSB-LC voltage signals are combined to provide a DSB-SC signal. The DSB-SC signal is synchronously demodulated using a quadrature reference carrier clock signal to provide an output baseband signal which represents the difference between the spacing of the first and second differential capacitor plates. <IMAGE>

Abstract: The occupation area and thickness of dielectrically isolated island-resident transistor structures, which employ a buried subcollector for providing low collector resistance at the bottom of the island, are reduced by tailoring the impurity concentration of a reduced thickness island region to provide a low resistance current path from an island location directly beneath the base region to the collector contact. The support substrate is biased at a voltage which is less than the collector voltage, so that the portion of the collector (island) directly beneath the emitter projection onto the base is depleted of carriers prior to the electric field at that location reaching BCVEO, so as not to effectively reduce BVCEO. Since the support substrate bias potential depletes some of the region of the island beneath the base region of carriers, the doping of the island can be increased compared to the case where the substrate is not biased, while maintaining the electric field at this location less than the BVCEO field.

Abstract: To generate in-phase and quadrature components for digital signals, a Hilbert transformer for phase shifting by 90 DEG  and a delay element for equalising the signal transit time of the Hilbert transformer are normally used. The usable bandwidth is limited by the fact that the Hilbert transformer has nulls in the frequency response of absolute amounts at frequency 0 Hz and at multiples of half the sampling frequency. In the device according to the present invention, these nulls are avoided since symmetric filters with a phase shift of 45 DEG  and -45 DEG , respectively, are used for generating two signals in a quadrature phase relationship, which results in a reduced complexity of implementation whilst retaining the same bandwidth. <IMAGE>
