Abstract: ABSTRACT (Fig 3) ELECTRONIC TYPEWRITER WITH A DEVICE FOR ZERO POSITIONING                 OF A ROTARY CHARACTER-CARRYING DEVICE     The electronic typewriter is of the 'daisywheel' type and comprises a microprocessor, a stepping selector motor controlled by a position register for positioning the daisywheel 28, and a support frame for a correction ribbon.  The support frame is arranged to oscillate from a down position for viewing purposes to an up position for the correction operation.  A tab (104) moves up and down with the frame.  The daisywheel rotates together with a sleeve member 97 provided with a stop seat 98.          The tab (104), in the up position, urges a tooth (99) on a lever (101) into interference with the sleeve member (97), via a resiliently yielding blade (107) of the lever (101).  During the correction cycles, rotary movement of the daisywheel (28) takes place when the support frame and hence the tab (104) is in its own position and thus without any obstacle.  In the initialisation phase, the microprocessor raises the support frame and tab (104) in advance of a command for complete rotation of the daisywheel (28).  This causes the tooth (99) to engage into the seat (98) and stops the daisywheel in its zero position. The position register is then loaded with a code corresponding to the zero position of the daisywheel, thereby being synchronised to the angular position thereof.

Abstract: NEUTRALIZATION OF ALKALI METAL CATALYSTS IN ORGAMOPOLYSILOXANES                          ABSTRACT           A process for the neutralization of the alkali metal catalyst in a polymerized organopolysiloxane, where the alkali metal content of the resulting organopolysiloxane is significantly reduced, is described.  The process consists of neutralizing the alkali metal salt with a straight-chain carboxylic acid of general formula ZCOOH, where Z is a hydrocarbon group containing at least two carbon atoms, and thereafter filtering the organopoly-siloxane.  The same ZCOOH carboxylic acids may be added to organopolysiloxanes which have previously been neutralized with either carbon dioxide or acetic acid in order to significantly reduce the alkali metal content of the organopolysiloxane after filtration.  Organopolysiloxanes containing less than 0.5 ppm K+  can be easily obtained.

Abstract: ABSTRACT OF DISCLOSURE          A loudspeaker system includes at least two loudspeaker drivers, together with an electrical crossover network having filter circuits with at least two separate mutually exclusive frequency passbands.  The filter circuits comprising the crossover network each possess brick-wall ampliltude responses, i.e., passbands with very high band-edge amplitude vs. frequency response slopes, on the order of 100 dB/octave in the better embodiments.  The high passband band-edge slopes, which are realized by the inclusion of transmission zeros in the seprate crossover filter transfer functions, taken together with further appropriate crossover filter transfer function synthesis causes the separate loudspeaker drivers comprising the loudspeaker system to function independently of one another in their contribution to total system acoustic output.  It is shown that the loudspeaker system permits an accurate approximation to the ideal delay function in acoustic space, while minimizing acoustic wave interference among drivers operating in adjacent frequency bands, and also reducing overall system nonlinear distortion.

Abstract: ABSTRACT: Cascode current-source arrangement.     A current source arrangement comprises a first and a second transistor (T1, T2) arranged in cascode between an output terminal (2) and the negative power-supply ter-minal (3). The arrangement further comprises a current mirror circuit, a current source (I1) connected to the positive power-supply terminal (5) being connected to an input current path which comprises a third transistor (T4) connected as a diode, a fourth transistor (T5) connected as a diode, and the collector-emitter path of a fifth transistor (T6), which input current path is coupled to a second current path comprising a sixth transistor (T7) whose base is connected to the base of the third transistor (T4), a resistor (R1), and a seventh transistor (T8) con-nected as a diode, whose base is connected to the base of the fifth (T6) and the second transistor (T2). Further, the base of the first transistor (T1) is connected to the emitter of the sixth transistor (T7). In this arrangement the collector-emitter voltage of the second transistor (T2) is equal to the collector-emitter voltage of the fifth transistor (T6), which is equal to the voltage across the resistor (R1). If the voltage across this resistor (R1) is substantially lower than one base-emitter voltage a comparatively low voltage is obtained on the collector of the first transistor (T1). Moreover, the ratio between the currents through the second and the fifth transistor (T2, T6) is defined accurately by the ratio between the emitter areas of these transistors.

Abstract: ABSTRACT            Improvements Relating to Rectractors The invention defines a plastics disposable,  hand applied medical retractor for retracting flesh at the edges of an incision or aperture in the human or animal body.   At one end the retractor has a sharply inturned hook portion on the end of which are short,  sharp, triangular teeth for impaling the flesh.    The retractor bows upwardly from the hook portion and back down to a pad which has an adhesive undersurface so that it can be pressed directly to the skin so as to anchor thereto to keep the pulled back flesh in the retracted position.   The said bowing allows the pulled back flesh to bunch upwardly to prevent such flesh from forcing the teeth out of engagement with the flesh and also provides inherent springiness tension in the retractor when it is applied improving its performance.          Instead of the pad having adhesive it may have one part touch and close fastener,  the other part being previously applied to the skin by pressure sensitive adhesive.

Abstract: ABSTRACT OF THE DISCLOSURE          A call progress monitor for a computer telephone interface system.  Energy detectors are connected to receive signals from a telephone line.  A bandpass filter is connected to the telephone  line,  having  selectable  center frequency.   A counter-timer connected to count clock pulses is reset by the energy  detector and timing commences  in response to  the presence of a signal on the telephone line.  The counter will result in a center frequency control means for the filter being slewed over a bandwidth of interest,  in synchronism with the counting of the timer-counter.  A signal detector connected to the filter indicates the presence of a pair of signal tones passing through  the filter as  it is  slewed. Decoding means are connected to the counter-timer and the signal detector for generating a binary signal indicating the frequency of the bandpass filter which passes each signal tone.  The binary signal is entered in a data register, and an interrupt posted to a host computer.  During the remaining portion of a counting cycle, a cadence interval is detected and  the  data  register  is  loaded  with  cadence  data. An interrupt  is  posted at the  end  of  the  cadence measuring interval for signalling the computer to read the contents of the data register.
