Abstract: ABSTRACT OF THE DISCLOSURE A ringing signal supply for supplying ringing current to a telephone line with high efficiency and minimum distortion.  As the ringing current demand of a load increases, distortion of the output signal is produced which causes an error signal to be generated after comparison of the output signal waveshape with a reference waveshape.  The error signal is used to change the duty cycle of a pulse signal from which the output ringing signal is produced, thereby maintaining the proper output signal waveshape.

Abstract: ABSTRACT          A frost plug immersion heater has improved clamping structure which comprises a clamp element having a base engageable against the inner end of the heater body and a pair of channel shaped clamping arms narrower than the base extending in splayed relation from opposite sides of the base, with the free ends of the arms initially close enough together so that the heater can be installed straight into a cylinder block frost plug hole.  A T-shape bolt has a cross arm bar shaped head which has opposite ends engaging in the arm channels and spreads the clamp arms when a nut threaded on the outer end portion of the bolt shank is tightened against the outer end of the heater body.  The cross arm head has a thickened crown area of maximum mass providing a maximum strength portion aligned with the shank of the bolt and the top of the cross arm tapers with diminished mass toward the opposite ends thereof to provide a truss-like reinforcement for the head when force is applied through the bolt shank as the nut is tightened.

Abstract: ABSTRACT OF DISCLOSURE     An edible compulsion comprises an integrally extruded not formed of an edible material e.g. a cereal-based, sugar-based or fat-based material.  The composition has a novel appearance and unexpectedly good eating qualities.   The net may be tubular planar or curved and may be filled and/or coated with a compatible edible material.     In the case of a tubular filled net, the net is preferably produced by extending the edible net-forming material through a pair of relatively rotating or oscillating dies having mutually engaging grooved surfaces.  When the grooves in one die mate with the grooves in the other die, integral joints between individual strands in the net are formed.  When the grooves in one die are separated from the grooves in the other die, the individual strands are formed.   A centre-filling, which may support the extruded net, is extruded through the centre of the net-forming die arrangement to provide a centre filling to the tube.

Abstract: INTERFEROMETER GYRO USING HETERODYNE PHASE DETECTION         ABSTRACT OF THE DISCLOSURE             An interferometer gyro includes a source of light which is divided and introduced into a light path in counter-rotating directions.          The light is removed from both counter-rotating directions after it has traversed the path one time, and the removed beams combined with a reference signal.  The phase difference between the two combined signals is determined to indicate the rotation of the optical path about which the light traversed.  In one embodiment, the signal and reference signals are modulated with frequencies, the difference between which is a frequency which is easily handleable with the electronic circuitry.

Abstract: ABSTRACT      A dual purpose suction cleaning apparatus includes an open-topped container adapted for the collection of a liquid and a motor driven air suction unit for applying suction to the container.   In use, either a detachable reservoir  unit,  or  a  detachable  connector  member  is interposed between the air suction unit and the container so that in the one case the apparatus serves as a water extraction cleaner, whereas in the other case it operates as a normal dry vacuum cleaner.   The inter-changeable reservoir unit and connector member are each formed as self-contained units by means of which the exhaust air flow from the suction unit is directed by the reservoir unit so as to displace liquid therefrom, but is diverted to atmosphere by the connector member.

Abstract: COLOR SOLID-STATE IMAGER AND METHOD             OF MAKING THE SAME            Abstract of the Disclosure A color, solid-state imager consists of a semiconductor body over which are successively laminated a predetermined number of filter layers of any desired shape having predetermined spectral characteristics.  Laminated on the filter layers is a predetermined number of layers composed of a transparent, organic high molecular material which is sensitive to radiation.  The semiconductor substrate has at least a detector portion composed of an array of a plurality of optical detector elements.  The method of making such imagers can be simplified by using the radiation-sensitive high molecular material for the intermediate layers or protective layers which are used for forming a laminate construction of color-decomposing filters.  In mounting the color-separating filters on the semiconductor substrate, it is particularly preferred first to form a film of an organic high molecular material.
