Abstract: Abstract:    The invention relates to a hose construction, and apparatus for continuously forming liquid-conveying hose therefrom.  The hose is for use mainly in agriculture to convey irrigating water.  To eliminate the necessity of transporting large masses of hoses full of liquid, the hose is formed only as it is actually needed and can be dismantled.  The hose is carried in the form of a sheet wound on a drum from which it is unwound, rolled round a pipe and its open, specially formed ends are closed and sealed into a tube by the application of a jointing strip and a sealing strip.  These strips are unwound from a separate drum.  The strip is essentially in the form of a series of open steel rings embedded in a backing material internally ribbed.  When the strip is inserted between the rims the latter are pressed against the ribs and so the hose is sealed.

Abstract: ABSTRACT The present invention concerns a new and improved storm window and window suspension arrangement for mounting a storm window frame in assembly with a frame of the window on a build-ing.  The storm window frame has a continuous annular resilient synthetic plastic spacer mounted on an inwardly facing surface of the frame for abutment against the frame carrying the window, the spring-loaded fasteners extend through the storm window frame for compressing the continuous annular resilient synthet-ic plastic spacer throughout its annular dimension and for se-curing the storm window frame in retained engagement with the window frame of the window, thus insuring a snug air-tight ass-emblage of the storm window on the window frame of the window. The storm window has an annular inwardly facing retaining groove with the synthetic plastic spacer being retainingly engaged and retained in the groove.  The plastic spacer when in the groove is positioned offset of an inside face of the storm window frame so that it can come into direct contact with the window frame. The fasteners serve to insure snug engagement of the storm win-dow frame with the window frame.  The window suspension arrange-ment also includes a window venting arrangement so that air can be admitted through the window frame, when desired.

Abstract: Abstract A solar dryer for particulate solids such as coffee, grain or the like, passes heated air from a series of solar modules into a drying chamber, the top of which is formed as a perforate tray for supporting the material to be dried.  Each solar module consists of a rectangular tube formed from insulating side and bottom walls and a translucent film extending across the top.  Inside the tube is an absorber to generate heat from solar energy that passes through the film and impinges on the absorber.  The absorber divides the tube into upper and lower chambers, while being inclined from one end to the other of the tube whereby the inflow air passes solely into the upper chamber and the outflow air passes solely from the lower chamber.  In between, the air must pass through the absorber, which is a pervious matrix of fibrous material, to be heated thereby.  The result is a dryer of improved simplicity and efficiency.

Each interconnection apparatus is associated with the 112 lines of a cable and has, for each subscriber line, an individual subscriber apparatus with an A/D and D/A converter whose digital output is connected to an outgoing multiplex and the digital input to an incoming multiplex, forming a PCM multiplex.  An interconnection apparatus comprises a multiplexor (30i), a multiplexor (31i) to which are connected seven PCMs, on one side, and a first link of 34 Mbit/s on the other, and a multiplexor (32i) to which is connected, on one side, the first link of multiplexor (30i) and a second link at 34 Mbit/s from the neighboring interconnection apparatus (HA(i-1)), and, on the other side, a third 34 Mbit/s link which is connected by transmission and reception system (33i), to a link (HBRLi).  A coupler (34i) is set up between the multiplexor link (31i) and a second link to the multiplexor (32(i+1)).  A unit (HAi) presents an analog structure through link (HBRLi).

Abstract: A TELEPHONE FOR A PHYSICALLY HANDICAPPED PERSON          Abstract of the Disclosure A telephone for a physically handicapped person has a transducer which is selected for easy actuation by the handicapped person.  The transducer may, for example, be operated orally.  When the transducer is first operated, a switch under the control of the transducer causes the telephone line switch to go "off hook" and, after a suitable delay, causes outpulsing of a zero signal to alert the operator.  Once contact with the operator is established, the caller who has access to a telephone microphone, asks the operator to place the call and subsequently participates in it.  Following the termination of the call, the transducer is operated again to reactuate the line switch and return the telephone set to its "on hook" condition.  A similar procedure is followed when a call is received by the handicapped person.  However, in this case, since no zero dialling is required, ringing voltage on the line is detected and, while present, zero dialling in response to transducer actuation is prevented.                            - i -

Abstract: ABSTRACT  NOISE DETECTOR AND SIGNAL RECEIVER ARRANGEMENT FOR A            FREQUENCY MODULATED RECEIVER       A noise detector and data signal receiver for a frequency modulation system has a first phaselock loop circuit (300), responsive to the received signal, for providing a signal indicative of the noise level and a first stage of demodulation of the received signal.  A high speed comparator (330) of the first phaselock loop circuit provides a 90 degree phase-shifted signal which exhibits lesser delay and is substantially in phase with the input.          Accordingly, the noise detection capability of the phaselock loop circuit (300) is improved. A second phaselock loop (200), also responsive to the received signal, extracts a voice signal from the received signal. third phaselock loop (400) responsive to the once demodulated output signal of the first phaselock loop (300), extracts a digital data signal from the received signal.  Squelch circuits (120,121), activated at separate particular levels of noise, are responsive to the noise level indicator signal of the first phaselock loop.          In addition, a noise proportional signal is provided to a speaker for providing the user of a hands-free telephone system of which the present receiver comprises a component with an audible feedback of the noise.

Abstract: ABSTRACT The present invention is a photoreceptor voltage control com-prising a comparator circuit for determing the error between the photo-receptor voltage and the desired voltage. The photoreceptor voltage is detected by a non-contacting detector and the photoreceptor voltage signal is fed directly to the comparator circuit which determines if the error is too positive, too negative or within acceptable limits. This information is then fedby a DC isolation system to the machine logic control which in turn corrects a corona supply voltage to obtain the desired photoreceptor voltage.

Abstract: A DEVICE FOR CORRECTING A VIDEOEFREQUENCY TELEVISION SIGNAL BY DYNAMIC ATTENUATION   OF THE NOISE LEVEL AND A TELEVISION IMAGE SOURCE EQUIPPED WITH SAID DEVICE     Abstract of the Disclosure A correcting device for dynamically reducing the noise pollution level with respect to a videofrequency signal mainly comprises an analog multiplier in which two pre-viously generated signal components are multiplied by each other.  One signal designated as the filtered signal is the result of a passage of the initial signal through a low-pass filter.  The other signal or so-called contour signal is the difference between the initial signal and the filtered signal.  The contour signal noise is cancelled at the time of the zero-crossings of the filtered signal and variably attenuated according to the level of the filtered signal in the case of the other levels of said signal.  Addition of the filtered signal and of the contour signal processed in accordance with the invention and suitably adjusted for amplitude reconstitutes a corrected videofrequency signal.
