Abstract: ABSTRACT OF THE DISCLOSURE A fuel burner sequencing means is disclosed which utilizes a bistable or alternate action switching means for safety checking.  The bistable switching means is specifically disclosed as a bistable relay that operates at the start of the cycle, and at the end of the cycle to check the operability of the safety checking means.  This same bistable relay means is used as a lockout means in the event of the failure of flame when a flame should exist in the burner, or when a flame is indicated and none should be present.

Abstract: ABSTRACT OF THE DISCLOSURE   In the illustrated embodiment, an electron collimator is to be mounted on the accessory holder of an electron accelerator.  In radiation therapy, the down beam end of the applicator is to contact the patient to establish a precise spacing of the electron source therefrom.  The legs of the L-shaped collimator plates have rods secured to the corner part thereof which link pairs of overlapping legs to a common carrier for joint lateral adjustment toward and away from the beam axis.  The rods slide in apertures in the carrier as the legs are adjusted longitudinally.  Cornered wall elements are secured to each collimator plate and overlap each other to surround the beam path, and have in-turned closely overlapping edges which terminate flush with the inner margins of the collimator plates so as to provide further electron collimation and to provide an essentially smooth patient contacting end face.

Abstract: Abstract of the Disclosure A system for generating a write clock signal for use with a rotating magnetic memory apparatus, such as a disk memory, in a data processing system which includes a slotted disk transducer which produces an intermediate pulse signal having a repetition rate related to the disk speed, a frequency-locked loop which produces a write clock pulse output signal having a repetition rate related to the intermediate repetition rate independently of variations in the disk speed.  The time response of the loop can be relatively low to lock the write clock output signal frequency to relatively slow variations in the intermediate frequency and to avoid locking to any extraneous high frequency variations therein.  A coded slot region provides a coded pulse sequence, having selected pulses missing therefrom which can be decoded for providing an index pulse, the missing pulses being supplied to the pulses from the transducer to form the intermediate pulse signal.  A sector identifying pulse signal can also be obtained from the intermediate pulse signal.

Abstract: ABSTRACT It is known to add formaline to urea to increase its mechanical strength.  Such process reduces the quality of the urea by increasing its water content.  It is also known to reduce direct formation in urea prills by coating them with formaline.  While this reduces dust it does not increase mechanical strength.  The products produced by the known methods are not suitable for use with modern bulk handling. The present invention seeks to overcome this drawback by providing in the crystallization or evaporation method for the production of urea the improvement comprising incorporating into the urea prior to prilling a formaldehydepolymer having a formaldehyde content from 82 to 97% and a melting point from about 90 to 160°C in an amount sufficient to provide 0.01 to 1% by weight based on the urea of formaldehyde.

Abstract: Abstract of the Disclosure Polymerizatlon of vinyl chloride monomer, by either sus-pension or emulsion polymerization, optionally in the presence of a monoethylenically unsaturated comonomer, is carried out in the presence of a mixture of calcium and zinc acrylate.  The presence of the calcium and zinc acrylate yield a more thermally stable product and reduces the amount of polymer scale formation during polymerization.  A further improvement in thermal stability is achieved by conducting the polymerization with the added presence of an epoxy compound containing a reactive vinyl or allyl group.

Abstract: SERVICE CONNECTOR FOR PLASTIC GAS MAIN          Abstract of the Disclosure Mating halves of plastic composition form a tapping sleeve service connector for mounting a branch connection on an in-service plastic gas main.  A tapping tool supported in communica-tion with the branch outlet is provided in one of the sleeve halves.  Emplaced lining the internal pipe gripping surfaces of the sleeve halves is a dual faced, open mesh, basket woven fabric containing a random distribution of particle abrasive bonded on each of the faces.  The particle abrasive is of a relatively harder composition than the plastics of either the service connec-tor or gas main to effectively penetrate or imbed in the opposed surfaces of each when the sleeve halves are assembled in place.        By being imbedded in this manner the abrasive fabric acts to secure and prevent relative rotational slippage between the service connector and pipe on which it is mounted.     1a

Abstract: RCA 72,017 SUPPRESSION OF LUMINANCE SIGNAL CONTAMINATION OF CHROMINANCE SIGNALS  IN A VIDEO SIGNAL PROCESSING SYSTEM       Abstract of the Disclosure Apparatus in a video signal processing system for improving the quality of a reproduced color image by reducing visible "cross-color" interference caused when high frequency luminance signals occur within the passband of the chrominance component of the video signal.  Video signals within the chrominance passband are sensed by a signal multiplier responsive to the video signal and to the video signal delayed by a given amount.  The amount of delay corresponds to an interval during which rapid lumi-nance transitions capable of producing the high frequency signals within the chrominance passband can occur.  The multiplier generates a control signal indicative of the presence of the luminance transitions, which is then utilized for controlling the chrominance signal processing channel such that objectionable cross-color effects otherwise visible in a reproduced image are reduced or eliminated.

Abstract: A B S T R A C T            A profiled wheel tread for use with self-steering wheelsets, the tread having a running surface, a wheel flange, a taping line passing through the running surface, and a running zone between the taping line and the wheel flange.  The invention provides that the effective conicity across the running zone decreases from the taping line towards the wheel flange.  In another form the effective conicity initially increases from the taping line, reaches a maximum at a lateral deflection of between 1,5 and 4 mm, and then decreases towards the wheel flange.  The wheel flange is thinner than normal to increase the gauge clearance.  Improvements are thereby obtained in wheel tread wear and rail wear by minimising creep forces;hunting stability, because the effective conicity at maximum lateral deflection is low; and steering ability,because of a high average conicity and increased gauge clearance.
