Abstract: ABSTRACT     This invention relates generally to electromagnetic flow meters, and more particularly to a flangeless flowmeter whose components are integrated to form a highly compact, low-cost unit that may be readily installed in. a flow line, the unit being compressible between the flanged ends of the upstream and downstream pipes and being capable of withstanding high compressive forces.     Magnetic flowmeters such as those disclosed in U.S.           Patents 3,695,104; 3,824,856; 3,783,687 and 3,965,738, are especially adapted to measure the volumetric flow rates of fluids which present difficult handling problems, such as corrosive acids, sewage and slurries.  Because the instrument is free of flow obstructions, it does not tend to plug or foul.           The flowmeter can be used to meter liquids without regard to heterogeneous consistency.     An added advantage of an obstructionless construction is that pressure losses are reduced to levels encountered in equivalent lengths of equal diameter pipeline, thereby reducing or conserving pressure source requirements in new or existing hydraulic lines as compared to other metering techniques.

Abstract: ABSTRACT A method of applying a metallic oxide coating to a moving ribbon of glass is disclosed for four thicknesses of glass, namely, 7/32; 3/16; 5/32 and 1/8 inch.  In each of these methods, first and second spray zones are esta-blished at opposite edges of the moving ribbon.  The spray zones are moved in a simultaneous manner at the same speed from one edge to the other edge whereby the spray zones pass each other at the center line of the moving ribbon. When each of the spray zones reach the opposite edge of the moving ribbon, their direction of travel is reversed so that they once again pass one another at the center line of the moving ribbon.  The first and second spray zones are spaced a slight distance from one another in the direction of move-ment of the moving ribbon.  The moving spray zones are cycled back and forth in the aforedescribed manner contin-uously as the ribbon of material is moved thereunder so that a coating is applied to the moving ribbon.  This method is used for applying a metal oxide coating to a moving ribbon of glass which is emerging from a float glass chamber.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to a flame resistant composite panel which can be shaped at room temperature with non-chip-for-ming processes and is made of a core of foamed thermoplastic material with metallic cover layers on both sides joined to the core by means of adhesive layers.     Composite panels of the above kind which have a plastic core containing e.g. polyolefines suffer from the disadvantage of having unfavourable flammability characteristics which are expressed in DIN 4102 as belonging to the classification of being of normal combustibility. For this reason such compo-site panels find only limited application, and in addition they can not be plastically deformed.     The disadvantages associated with such composite panels are avoided by a number of measures such as providing the foamed rigid PVC core with a special surface finish which permits the use of a relatively thin layer of adhesive bet-ween the core and both cover sheets.

Abstract: ABSTRACT OF THE DISCLOSURE    A hand brake mechanism of the quick-release type having locking structure preventing accidental brake release includes a clutch collar interconnecting a drive member mounted on a shaft for rotation therewith and a pinion mounted on the shaft for rotation relative thereto and for being operatively connected in a power train to the car brakes.  The collar is shiftable on the shaft between a drive position making the aforesaid inter-connection, and a brake-release position wherein the connection is broken and the pinion is freely rotatable on the shaft.  A pivotally mounted shift lever has collar-engaging members for shifting the collar between such positions. A cam shaft is provided with a cam which, when the cam shaft is rotated in one direction, engages the shift lever to shift the collar into the brake-release position.  The cam shaft also is provided with a reaction member having a cam surface which, when the cam shaft is rotated in the opposite direction, engages the shift lever to shift the collar into the drive position, and having a stop surface which engages the shift lever when the collar is in the drive position, to positively and mechanically lock the collar in the drive position.   A second reaction member is provided on the cam shaft, in a preferred structure, such member engaging the collar when it is in the drive position, also to positively and mechanically lock the collar in its drive position.  Any forces which may be experienced, tending to shift the collar out of its drive position when locked therein by the reaction members, act on the reaction members in opposite directions, so that the forces are assimilated by the cam shaft.

Abstract: COMBUSTION INITIATION SYSTEM                 ABSTRACT OF THE DISCLOSURE           A combustion initiation system includes an initiating device for producing, containing and propell-ing a combustion initiating plasma having an energy density approaching that produced by combustion of the fuel itself, and is suitable for initiating combustion in relatively lean mixtures of various types of fuels.  A high voltage power supply delivers electrical energy by a coaxial cable to the initiating device which communi-cates with a fuel mixture in a combustion area such as the combustion chamber of an ordinary internal combus-tion engine.  The initiating device includes a capaci-tive portion for storing a large quantity of electrical energy therein derived from the power supply, and an electrode portion integral with the capacitive portion which comprises a pair of concentric, rod shaped elec-trodes for producing a high energy, umbrella shaped plasma discharge, using the inverse pinch technique. Due to the close proximity between the capacitive and elec-trode portions of the initating device, rapid energy transfer from the former to the latter creates high magnetic pressures which transform the discharge into a high energy plasma jet which is delivered well into the combustion area.

Abstract: ABSTRACT OF THE DISCLOSURE         A vertical-rate sawtooth waveform amplitude modulates a train of horizontal-rate pulses. Positive and negative pulse clippers receive the pulse train.  One generates a clipped waveform during the last half, and zero output for the first half, of a television field.  The other generates a clipped waveform during the first half and a zero output the last half of the field.  A pair of AC coupled integrators, driven by respective clipped waveforms, generate horizontal-rate sawtooths which are linearly modulated, one from a maximum at the beginning of the field to zero at the center thereof, and one from zero at the center to a maximum at the end of the field.  Two pairs of clippers separate the two sawtooths into four half-sawtooths, wherein each is active in a time interval corresponding to respective quadrants of the picture raster.  Potentiometers are used to vary the respective waveforms to allow indepen-dent correction of the scan in any corner.
