Abstract: ABSTRACT OF THE DISCLOSURE              A suction attachment for a vacuum cleaner has a housing component and a brush component which is accommodated within the housing component. Two mounting members mount the brush component in the housing component for displacement be-tween a retracted position in which the brushes of the brush component are received within the housing component, and an ex-tended position in which the brushes extend to the exterior of the housing component and into contact with a surface to be vacuum cleaned. The mounting components are interconnected by connecting members for synchronous pivoting about spaced pivot axes. Each mounting member is pivotally mounted on the brush com-ponent and has a support portion which engages the housing compon-ent. One of the mounting members has an actuating portion which is acted upon by an actuating element for pivoting the mounting members into positions corresponding to the extended position of the brush component against a biasing force, and a releasing portion acted upon by a flexible portion of the actuating element for releasing the mounting members and the brush component for displacement of the latter toward the retracted position. The other mounting member may have faces of distinctive appearance which are visible through a window of the housing component and indicate the position of the brush component.

Abstract: ABSTRACT OF THE DISCLOSURE            The disclosure describes a process for refining a gas which contains hydrogen sulfide, sulfur oxides and nitrogen oxides and may contain hydrogen cyanide as contaminants.  The process comprises contacting the gas with an absorption medium to absorb the contaminants in the absorption medium.  The absorp-tion medium contains as catalytic component specified naphtho-quino-chelate prepared by mixing (A) naphthoquinone or a deriva-tive thereof of the general formula   or naphthodiquinone or a derivative thereof the general formula   in which X represents hydrogen atom, hydroxyl group, a lower alkyl group, a lower alkoxy group, sulfonic group (-SO3H), car-boxylic group (-COOH), an alkaline metal or alkaline earth metal salt of sulfonic or carboxylic group (such as -SO3Na, -COONa), thioglycol group (-S-CH2-COOH) or thiol group (-SR in which R is a lower alkyl group) with (B) a precursor of a chelating agent which is selected from the group consisting of the reaction product of a metal selected from the group consisting of the metals of groups V, VI, VII and VIII in the fourth period of the Periodic Table, arsenic and selenium with an acid selected from the group consisting of oxalic, citric, tartaric and glutaric acids and aging the mixture of (A) and (B) to form a naphthoquino-chelate compound.  The absorption medium further contains as solvent specified diamine selected from among cyclohexadiamine and diamine having the general formula NH2(CnH2n)NH2 in which n is 2, 3 or 4 and mono-, di-, tri- or tetra-acetate, or mono-, di-, tri- or tetra-propionate, or mono-, di-, tri- or tetra-buthylate of said diamine.  The ab-sorption medium which has absorbed the contaminants is treated for obtaining sulfur from hydrogen sulfide and sulfur oxides and thiocyanate from hydrogen cyanide while producing a gas having high nitrogen oxides concentration.  This process is less polluting than known processes.

Abstract: ABSTRACT OF THE DISCLOSURE            A method of and apparatus for recording a video signal in successive parallel tracks on a record medium, and for repro-ducing the recorded signal.  The video signal, which may be the luminance component of a composite color television signal, frequency modulates a carrier to produce a frequency modulated video signal. The phase of frequency modulated video signal is selectively shifted in selected line intervals and is recorded in parallel tracks such that the phase difference between frequency modulated video signals in at least some adjacently recorded line intervals of successive tracks is an odd multiple of ?.  In one embodiment, the difference between the phase of alternate line intervals which are recorded in one track and the phase of alternate line intervals which are recorded in the next adjacent track is equal to an odd multiple of ?.  In accordance with another embodiment, the differ-ence between the phases of successive line intervals which are recorded in the same track is equal to an odd multiple of ?. The phase shift is attained by inserting a pulse signal into selected line intervals of the video signal in advance of the frequency modu-lation.  During reproducing, the successive tracks are scanned and the frequency modulated signals recorded therein and reproduced to-gether with a crosstalk component which is picked up by the transducer from  an adjacent track, the crosstalk components being out of phase with each other.  The reproduced frequency modulated signal is de-modulated so as to recover the original video signal and the in-serted pulse signal, the latter being eliminated form the recovered video signal.                             -i-

Abstract: SPECIFICATION ABSTRACT OF THE DISCLOSURE         A circuit for correcting an AC output signal from an electronic device into closer correspondence with an AC input signal to the combination of the circuit and device comprises first and second amplifiers arranged to each receive the input signal.  The first amplifier is also arranged to receive feedback of the output signal from the electronic device for providing a signal which is a function of the difference between the input and output signals.  The com-bination of signals from the first and second amplifiers is provided to the electronic device for producing an output signal which corresponds closely to the input signal. In a method of operating the circuit with an electronic device from which the output signal variably differs from the input signal, the amplitude of the output signal fed back into the first amplifier is adjusted to provide a null AC signal from the first amplifier at the output signal which deviates least from that desired.  Then, when the input signal changes to produce an output signal which would deviate more than the minimum from that desired, the first amplifier pro-duces a signal which varies inversely to the deviation to correct the output signal from the device.

Abstract: Abstract of the Disclosure In a printing apparatus adapted to work on the electrophotographic principle there are disposed between a light source and a rotating mirror or a photoelectric data carrier optical components by means of which the light beam being emitted from the light source is shaped and focused.  These optical components are combined to form an optical unit which is mounted on two guide rails for displacement therealong.  These are attached at their ends to two attachment pieces, each of which has a centering pin.  The optical unit is positioned in the printing apparatus by sliding the centering pins into centering bores which are provided in the printing apparatus.  This permits an accurate positioning of the optical unit in the beam between light source and rotating mirror or data carrier.  Preferably the guide rails have a circular cross-section and the mountings are rotatable about one of the guide rails.  The extent of the rotation is determined by an adjuster screw which can be screwed through the mounting towards the other of the guide rails.

Abstract: ABSTRACT OF THE DISCLOSURE             Disclosed herein is a starter mechanism for an engine having a starter gear, which starter mechanism includes a rotatable starter shaft, a starter pinion rotatably mounted on the starter shaft for axial movement, in response to rotation of the starter shaft in one direc-tion, to an engine starting position in driving engagement with the engine starter gear, and a drive member mounted for rotation coaxially with the starter shaft and drivingly connected to the starter shaft.  Manual starting of the engine is selectively effected by rotating a circular member or rotor drivingly connected to the drive member through a first one-way clutch which, in response to rotation of the rotor in the one direction, affords common rotary movement of the rotor and the drive member and permits free wheeling of the drive member relative to the rotor in the same direc-tion when the rotor is not operated.  Powered starting of the engine is selectively effected, independently of the manual starter, by a power unit including a driven gear mounted coaxially with the drive member and drivingly con-nected to the drive member through a second one-way clutch which, in response to operation of the power unit, affords common rotary movement of the drive gear and the drive member in the one direction and which permits free wheeling of the drive member relative to the driven gear in the same direction when the power unit is not operated.
