Abstract: ABSTRACT             A process for the preparation of a sterile iniectable physiologically acceptable solution of an X-ray contrast agent and solutions of the X-ray contrast agent and a buffer Sterile, injectable, physiologically acceptable solutions of an X-ray contrast agent are prepared by autoclaving a solution-of a m-carboxamido-o-iodo-N-(.beta.-hydroxyalkyl)aniline X-ray contrast agent in the presence of a physiologically acceptable buffer system the pH of which decreases with increasing temperature.       The presence of a temperature dependent buffer, preferably an amine, enables X-ray contrast agents to be sterilized by autoclaving without significant decomposition.   Examples of the autoclaving processes are given and solutions for autoclaving containing a m-carboxamido-o-iodo-N-(.beta.-hydroxyalkyl)aniline  X-ray contrast agent and a physiologically acceptable buffer system the pH of which decreases with increasing temperature are described and claimed.

Abstract: ABSTRACT         The present invention is directed to a process for nitrosamine control in nitrite cured meats and speci-fic compositions to effect the process.  An effective amount of starter culture and/or chemical acidulant is added to a typical nitrite pickle or curing solution for treating meats to reduce the quantity of nitrosamine formed when the cured meat is cooked at frying tempera-tures.  The starter culture is capable of producing an organic acid from fermentable carbohydrate.  In a speci-fic embodiment of the invention, bacon is cured with a nitrite curing solution containing an amount of lactic acid starter culture and/or chemical acidulant in an amount effective to reduce the quantity of nitrosamine formed during cooking of the nitrite cured bacon.

Abstract: PEELING APPARATUS Abstract of the Disclosure Apparatus for peeling exterior surfaces of elongated generally cylindrical workpieces includes a cutter head rotatable about an axis and having at least one slide mounted thereon for movement generally radially of the axis. A cutter holder has a cutter mounted thereto and is itself mounted on the slide for movement generally toward and away from the rotational axis of the cutter head. A spring assembly is interposed between the slide and holder for biasing the holder generally toward the rotational axis of the cutter head. A follower on the holder engages the ex-terior surface of a workpiece ahead of the cutter for main-taining a uniform relationship between the cutter and work-piece for peeling a substantially uniform layer from the workpiece despite any out-of-roundness. The holder is movably mounted to the slide by a hinge connection. The cutting forces are transmitted to the holder along a force vector line which passes through the hinge connection. The force vector line makes an included angle of between 10-25 with a tangent line which is tangent to the exterior surface of the workpiece at the cutting point.

Abstract: ABSTRACT OF THE INVENTION     A strand break-out device for preventing the formation of fault yarns due to strand breakage when two unspun fibrous strands are spun on a common twisting spindle.  A member      has pins      forming a passage means to which the strands converge during travel to the spindle and on which the strands may bear to apply force to the member.  The member is pivotally mounted on a support      so that it may move freely on the support between limits of displacement from a mean, stable dis-position.  If a strand breaks the force applied by the remaining strand moves the member beyond the respective limit whereupon the member moves to a further position wherein the pins distort the path that the remaining strand would otherwise take.  This distortion is such as to cause the remaining strand to break.

Abstract: Abstract of the Disclosure A three-terminal power supply circuit for telephone set has an input terminal, an output terminal and a common terminal.  The input terminal receives a DC voltage superposed with a sending or receiving signal transmitted to or from a telephone station through a subscriber line.  The output terminal delivers a DC power to a telephone circuit.  Between the input and output terminals a constant current circuit and a discharge protection circuit are connected to each other in series.  Between the output terminal and the common terminal a constant voltage circuit is connected. between the input terminal and the common terminal an electronic switch is connected through the constant current circuit.  The electronic switch is closed only when an instantaneous voltage applied between the input terminal and the common terminal is lowered to a prede-termined value or a lower value.  When it is closed, the electronic switch causes short circuit in the constant voltage circuit through discharge protection circuit.          This lower the cutoff voltage applied on the input side of the power supply circuit, and both a sending signal and a receiving signal can be transmitted without being distorted.

Abstract: ABSTRACT OF THE INVENTION                 "FREQUENCY MODULATION"       A frequency modulatable oscillator arrangement has a frequency controllable oscillator (VCO) whose output frequency (f) is stabilised by means of a reference oscilla-tion (fref) via a phase regulating loop comprising a phase comparator (P) and a loop filter (TP).  In order that a frequency modulator of this kind can process d.c. components in the case of a modulation signal (sm) in keyed form without the need to dispense with the limitation of the modulation spectrum, the modulation signal is fed via a modulation filter (MTP) to the control input (e) for direct control of the oscillator frequency and also to a frequency divider (FT) included in the phase regulating loop so as to control its division ratio.

Abstract: Abstract of the disclosure:   To mix two or more fluid plastic components, which react with one another, intimately and abruptly, the components are injected under high pressure and at high velocity into a mixing chamber.  To provide greater control of the type of mixing, ie. to allow control of the spread of the jet and/or the jet volume and the jet energy losses, the com-ponents are guided so that they impinge on one another at an angle, preferably an angle which can be varied. To achieve this, and in particular to allow the point of impingement of the jets to be varied, the in-jection nozzles can be slid or pivoted at right angles to the lengthwise axis of the mixing chamber, and may also be adjustable in the direction of the said axis, and in respect of their distance from the axis.
