Abstract: Abstract:           A hydrostatic or pneumatic drive for driving a mass to be accelerated and decelerated, such as in a die casting or injection moulding machine, has a controllable valve arrange-ment which is operable to vary the fluid flow rate therethrough. The fluid flow rate is controlled by a reference value control generator operable to produce a ramp having superimposed thereon further control pulses.  Such control pulses are a positive control pulse at the beginning of the rising slope and at the end of the falling slope of the ramp and a negative control pulse at the end of the rising slope and at the beginning of the falling slope of the ramp.  Each control pulse has a volume which corresponds to a so-called compression volume factor which reflects the compressibility of the fluid used in the drive and also of the elasticity of ducts which expand by fluid pressure.

Abstract: ABSTRACT OF THE DISCLOSURE           A non-destructive testing technique, particu-larly suitable for the non-invasive examination of human body tissue, wherein the object of interest is sequen-tially transilluminated with light having different wavelengths.  Apparatus for practicing the technique alternately generates light of different colors and the light which passes through the tissue is detected by a video system synchronized with the source of the different wavelength light.  The video system provides information bearing signals to data processing circuitry which determines the transmissivity at each wavelength of each point of the object within the viewing field.

Abstract: ABSTRACT OF THE DISCLOSURE        A charge transfer device has one or more charge injection areas each having an input diffusion layer and two or more input gate electrodes.  An input signal is applied to the input diffusion layer, a clock voltage is applied to one of the input gates and an input reference voltage is applied to the other input gate to inject a signal charge proportional to a difference between the input reference voltage and the input signal, and the signal charge is sequentially transferred.  A magnitude of the input reference voltage is changed in accordance with a magnitude of a maximum value of the input signal so that transfer of charges which do not contribute to signal component is suppressed and a transfer efficiency is improved.

Abstract: ABSTRACT OF THE DISCLOSURE         An electrical cable has features that allow its use in wells containing oil, water and gas, for use with submersible pumps.  The cable has a number of conductors. Each conductor is surrounded by an insulating layer of oil and brine resistant thermosetting material.  The insulating layer is permeable to gas.  A polymeric jacket is extruded around all of the conductors, separating the conductors from each other and in direct physical contact with the insulating layers.  Perforations are placed in the jacket at regular intervals.  During rapid depressurization, gas absorbed in the insulating layers is able to flow freely from the cable by means of the perforations in the jacket. The jacket has sufficient strength to prevent rupturing of the insulating layers during depressurization.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for converting radiant energy levels to digital data wherein an image sensor is provided having at least one row of sensor elements each including a light sensitive capacitor and an access switch and which changes state and produces a corresponding binary output signal when a predetermined charge threshold is exceeded by the capacitor whose charge is a function of intensity and period of an illumination.  The row of elements is first calibrated by illuminating same with a reference light source and sensing at a first frequency (F) such that approximately one half of the elements change state and counting the digital output signals corresponding to the changes of state to obtain a first number (B). Thereafter, the row is illuminated with an unknown light source which has a lower radiant energy level than that of the reference light source and senses at a frequency F/2. The digital output signals corresponding to the changes of state are counted to obtain a second number (A).  The numbers A and B are compared to produce a digital "1" signal when A > B and a digital "0" when A < B corresponding to digital data bit N1.  The sensing and comparing are repeated for each successive bit N2, N3...Nk of a K bits of digital data at successive sensing frequencies in accordance with

Abstract: ABSTRACT     A prosthetic device adapted to be secured to a supporting bone by a thickness of acrylic bone cement.  The prosthetic device has an outer surface which includes a plurality of spacers pro-jecting therefrom.  The spacers are made of an acrylic material such as polymethyl methacrylate (PMMA), and are adapted so that when the prosthetic device is positioned against the supporting bone, the spacers provide a uniform space between the bone and prosthetic device, thus uniformily controlling the thickness of cement.  The acrylic spacers will repolymerize and bond with the layer of acrylic bone cement.  The nature of the bond formed between the new acrylic bone cement and the acrylic spacers should eliminate the stress concentrations at the interface between the spacers and the cement layer, thereby enhancing fixation of the prosthesis.

Abstract: Abstract:            A waste paper recycling process relates to the treat-ment of a mixture of waste paper containing non-cellulosic contraries and printing inks, in order to release the contraries from the fibers and further to separate them from the stock in order to produce re-usable pulp for the production of paper and board.  The invention has to do with new and useful improvements in methods for first removing the non-ink contraries from the fibrous mass and second releasing and then removing the ink particles from the said fibrous mass.  The invention is directed to the treatment of the fiber slurry produced during the ink separation stage, after the ink releasing stage has been applied.  One aim of the process is to allow both the use of the fibers and the mineral fillers contained in that slurry, for pulp and board making, and the use of the solids-free water contained in the same slurry as the washing liquid in the previous ink-separation treatment, thus closing the fibers and the water circuits.  This process includes chemical and thermo-mechanical treatments, starting under alkaline conditions, which may become neutral at the end of the process.

Abstract: ABSTRACT: A loudspeaker system and a loudspeaker for use in a loud-speaker system for converting an n-bit digitized elec-tric signal into an acoustic signal.           An electrodynamic transducer (1) for use in a loudspeaker system for converting an n-bit digitized electric signal (11) into an acoustic signal comprises n voice-coil devices (4.1, 4.2, ... 4.n) which cooperate with a magnet system (3). The voice-coil devices each comprise a conductor whose length is the same for all the voice-coil devices. The areas of the perpendicular cross-sections of the conductors increase each time by a factor of two starting from the voice-coil device (4.n) corresponding to the least significant bit and going to voice-coil devices corresponding to consecutive more sig-nificant bits. In accordance with the invention steps are proposed which enable such a transducer to be con-structed in a simple manner if the transducer is a mov-ing-coil loudspeaker (Fig. 2b) or if the transducer is a ribbon-type loudspeaker (Figs. 4b and 4c).

Abstract: Abstract:            Electrical-charge sensing flowmeter An element interacting with a stream of a  fluid moving through a pipe generates periodic sub-flows at a rate that varies in accordance with changes in the velocity of the moving fluid.  The generation of sub-flows also modulates the electrical charges contained in and moving with the fluid thus permitting a detector which is responsive to the energy being radiated by the modulated charges to produce a sensor signal having a frequency corresponding to the generating rate of the periodically produced sub-flows.    In  one  preferred  embodiment,  the  element  is  a vortex-shedding  body  and  the  sub-flows  are  vortices being  shed  therefrom.   Electrical  circuitry  which receives  the  sensor  signal  converts  it  into  a  flow signal representative  of the  velocity  of the  moving fluid.
