Abstract: CORNER FORMATION FOR ARCHITECTURAL GLAZING STRIP          Abstract of the Disclosure A corner formation is made in an architectural glazing strip that has an elastomer-encased spring member formed of a resilient wire element in a transverse pattern of zig-zag loops with the strip having an anchorage edge and a glass-engaging edge.          To form a corner, the strip is cut inward from the anchorage edge between a pair of wire loops, and the cut is stopped at the wire extending between the pair of loops.  Then the strip is bent 90° to open a substantially square space between the wire loops.  A resilient element is placed in this space and has substantially the same transverse cross-sectional shape as the spring member, and an elastomeric material encases the resilient element and is secured to the strip around the corner.  The result provides an even and uniform corner having resilient pressure all the way around the corner.

Abstract: A B S T R A C T             A method of diverting from a supply of grains a plurality of parallel intermittent single flows of grains, especially for sowing one seed in each one of a number of plant growing pots. The method comprises the steps of causing the grains of the supply to move in a definite direction on a plane support by utilizing vibration feed, and dividing the resulting wide grain flow into a plurality of paral-lel single-row flows by guiding said wide grain flow into a corre-sponding number of grain paths connected to said plane. For this pur-pose each of said grain paths is designed so as to be able to convey only a single row of grains. Further, each grain path cooperates with one grain-carrying cavity for transferring the grains one by one to said cavity which rotates about an axle and discharges the grains at predetermined time intervals in accurately determined po-sitions after rotation through a certain angle.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to real time control either in compression or expansion of the amplitude of electrical waves and more specifically to a real time expander or compressor of the amplitude of sound waves.  In general a source of waves which may be the electrical equivalent of a sound including continuous discourse is applied to a plurality of first filters whose output is connected to respective power circuits.  A power circuit produces at its output a wave whose amplitude is a power, either greater or less than one, of the amplitude of the wave applied to its input.  The outputs of the power circuits are applied to respective second filters which are similar to the filters connected to the input of the power circuits and the output of the second filters is connected to a utilization device.  Amplifiers may be connected where needed.  The electrical wave applied to the utilization device is a real time compressed or expanded version of the wave applied to the first filters depending on whether the power is less than or greater than one, since the compression or expansion takes place in the power circuits and there is no delay in them.

Abstract: ABSTRACT OF THE DISCLOSURE       Smoke detection apparatus including a pair of photo-electric cells which receive illumination in a predetermined ratio from a very low level light source.  An improved simulating device is included for the purpose of testing the correct functioning of the alarm system connected to a sensing circuit formed by the photocells.  The effects normally produced by smoke present in a chamber are simulated by selectively directing light from an auxil-iary light source onto the sensing or "reflected" cell in the sensing circuit.  In addition, a specially designed and constructed sensor head is provided fro avoiding discrepancies in the placement of the critical elements; moreover, improved flow of any smoke present is promoted by the specific geometry of the sensor head.      Also, discrepancies between the desired and actual ration of illum-ination received by the respective photocells can be readily ad-justed for electrically, and the light ratio between photocells can be changed by suitably adjusting the degree of illumination received by the direct cell.
