Abstract: A combined air-rubber spring has a load-bearing plate 8 and a bell-shaped rubber component 1 which supports the load-bearing plate 8, consists of a hollow-cylindrical side wall 2 and an end wall 3 extending essentially radially, and is closed in a sealed manner by a base plate 4, extending radially, which, together with the side wall 2 and the end wall 3 of the rubber component 1, delineates a pressure chamber 5 which can be filled with air, the end wall 2 of the rubber component 1 consisting of a central, circular section 6 and an annular edge section 7 arranged coaxially about the central, circular section 6. To increase the vibration-damping and shock-absorbing effect of the spring, and to prevent failure of the spring in the event of an overload, the annular edge section 7 of the end wall 3 of the bell- shaped rubber component 1 is constructed as a truncated cone and one or more feet 9 project in the axial direction into the pressure chamber 5 from the central circular section 6 of the end wall 3 of the bell-shaped rubber component 1, the free ends of which feet 9 are at an axial distance from the base plate 4 when the spring is in the undeformed state, and the other ends thereof are firmly connected to the load-bearing plate 8. The pressure chamber 5 can additionally be partially filled with fluid 14, into which the feet 9 dip with a radially broadened section 15, arranged in the region of their free ends, to improve even further the damping characteristics of the spring.

Abstract: A photographic camera has a motorized film transport mechanism (55, 57) which is operable normally to prewind substantially the entire length of a filmstrip (F) from a light-tight cartridge (C) onto a take-up spool (1) without exposing any of the frames on the filmstrip and to rewind the filmstrip one frame at a time back into the cartridge after each exposure is completed. If a rear door (5) of the camera is accidentially or inadvertently opened before the filmstrip is completely wound off the take-up spool, the exposed frames within the cartridge are protected from stray light. However, the film remaining on the take-up spool may be ruined. Therefore, a door-open sensor (SW D ) and a film-on-spool sensor (43, SW F ) are provided which cooperate with a control circuit, when the rear door is opened, to operate the motorized film transport mechanism to continuously rewind the film on the take-up spool into the cartridge.

Abstract: The present invention provides a process for production of foamed articles of a polypropylene resin which comprises compressing pre-expanded beads of the propylene resin under a gaseous pressure, filling a mold which can be closed but cannot be sealed with the compressed beads, then venting the mold and heating and fusing the beads with steam thereby producing the molded article in the shape of the mold. The process is characterized in that pre-expanded beads of a poly­propylene resin having two melting points when measured by differential scanning calorimetry and having a quantity of the peak fusion heat QH based on the melting point at the high temperature peak of the two melting points of 0.3 to 3.5 cal/g are introduced into the mold at a compression rate is 10 to 60%. According to the present invention, foamed articles of polypropylene having a minimized dimensional shrinkage rate (good dimensional accuracy) and excellent fusion rate and surface appearance can be produced in high productivity.

Abstract: A processor for carrying out modulo reduction of a floating-point data by use of a predetermined constant is disclosed. A subtraction operation of more significant bits of the predetermined constant from a mantissa part data of the floating-point data is performed and the subtraction result is normalized. Less significant bits data of the constant is shifted and this result is subtracted from the above normalized data, this subtraction result being then normalized. Thus, a remainder caused by the modulo reduction is obtained.

Abstract: The invention relates a real time, multiuser, time-share computer systems particularly adapted for running computer software written for individual personal computers, including software that requires the interactive exchange of high resolution computer graphics information. Data is transferred between the host computer and remote terminals over a very high speed serial data transmission line at a rate of, for example, 25 MHz. Fiber optic duplex cables connect a host controller with one or more remote terminals. One fiber optic cable carries the data from the host controller to the remote terminal and the other cable carries data from the remote terminal to the host controller. Specially dedicated, high speed, hardwired electronic logic, such as 74F series TTL hardwired logic, encodes the software commands, transfers the data over a serial data link, and decodes the data so that slower speed hardware may direct the data to the appropriate operating hardware. The data link can connect terminals in a real time, time-share network that enables remote stations to share hardware and software written for the single user, single tasking generation of personal computer without modification to the software, including software having high resolution, interactive graphics.

Abstract: The circuit arrangement has an amplitude limiter (7) which is supplied with a frequency-modulated picture signal and the output of which is coupled to a frequency demodulator (8, 9). The output signal of the amplitude limiter (7) is supplied via a delay section (8), which can be a part of the frequency demodulator (8, 9), to a low-pass filter (12) the output signal of which follows the fluctuations of the mean value in time of the output signal of the delay section (8). The delay time of the delay section (8) is of the order of magnitude of one quarter of the carrier period of the frequency-modulated picture signal. The output signal of the low-pass filter (12) is the threshold value of the amplitude limiter (7) which switches the polarity of its output signal when the frequency-modulated picture signal intersects this threshold value.

Abstract: Apparatus for indicating the timing relation­ship between a reference point of a repetitive input signal, e. g. the horizontal sync point of a video signal, and a signal element that repeats at a higher frequency than the input signal, e. g. an element of the color burst, comprises a phase-­locked oscillator for generating a continuous wave signal that is in phase with the signal element. The continuous wave signal is used to generate a train of pulses having a repetition frequency that is equal to the repetition frequency of the signal element and is selectively variable in phase rela­tive to the continuous wave signal, and this train of pulses is used to modulate a display of the repetitive input signal in a dimension other than one that is used in a normal waveform display, e.g. intensity. By alternately bringing the pulse train into phase with the reference point of the input signal and the higher frequency signal element, the phase relationship between the signal element and the reference point can be determined from the required phase adjustment.

Abstract: An apparatus and method for determining three characteristics of strata cut by a borehole on a "real time" basis, namely, the internal friction angle φ , porosity Φ, and fracture probability pr(frac). To calculate the internal friction angle φ, the invention simulates apparent and theoretical model formulae of a chosen physical characteristic of a drill bit operating within a borehole. The apparent model formula is an accurate mathematical formula of the chosen physical characteristic, and the parameters of the formula are all known constant values or varying values measured by sensors. The theoretical model formula is a mathematical representation of the chosen physical characteristic, and it has one unknown parameter, the internal friction angle φ. The theoretical model formula is set equal to the apparent model formula, and the internal friction angle  0  is interatively determined. The internal friction angle φ is then used to calculate porosity from the relationship given by     The parameters A and K are calibration transform coefficients calibrated from values of "average" porosity as determined by several nearby wells. The facture probability of the formation is calculated from the relationship given by     where CR is the cohesive rating and ΦR is the porosity rating.
