Title: Dc motor reversing system including protective features responsive to reversing selector and to dynamic breaking current
IPC: H02P7/298
Filed: 1970-03-24
Abstract: In the forward-run position of a selector switch S1-S5, the armature A of a reversible motor M is supplied from a bridge rectifier PS, comprising phase-controlled thyristors SCR1, SCR2, through a series thyristor SCR3. A freewheeling diode DF ensures correct commutation of the thyristors SCR1, SCR2. To brake the motor, the selector switch is adjusted to shortcircuit the output of a gate pulse source GS whereby the thyristors SCR1, SCR2 are blocked. The gate and cathode of the thyristor SCR3 are short-circuited so that this thyristor is turnedoff A network BSC is connected across the armature A, a thyristor SCR4 being turned-on to complete a circuit through braking-resistor RB and relay Y. Contacts X1, X2, are actuated to ensure that the thyristors SCR3, SCR1, SCR2, are kept turned-off until the motor has stopped. If the selector switch is adjusted to the reverse-run position during a braking operation, the thyristor SCR4 stops conducting and the contacts X1, X2 return to their open state when the armature current reaches zero. The armature current is then reversed, the thyristors SCR1, SCR2, SCR3 being turned-on. The thyristor SCR4 is turned-off while capacitor Cl is charged to prevent rising voltages caused by the turning-on of thyristors SCR1, SCR2, from being impressed across the thyristor SCR4, which could be damaging thereto. If the A.C. source is disconnected from rectifier bridge PS and the selector switch moved to the reverse position which the motor is operating forwardly, and the A.C. source is then re-connected, the capacitor C1 supplies sufficient voltage to fire the rectifier SCR4 and to energize relay Y. The motor is thus braked to a standstill before its armature is re-energized.

Title: Acrylic multi-coloured textile products having tone-on-tone effect and process for producing the same
IPC: D06P3/87
Filed: 1970-06-15
Abstract: Fibrous textile products, e.g. yarn, comprise acrylic fibres P containing acidic groups and acrylic fibres Q containing both acidic and basic groups, the fibres satisfying the inequalities 3#(A-B)#1/ 3 C where C <30 or 5#(A-B)#1/4C where C#30 in which A and B are respectively the m.eq./kg. of the acidic and basic groups in fibres Q and C is the m.eq./kg. of the acidic groups in fibres P. The products show tone-ontone dyeing from a single dyebath containing a cationic dyestuff. Other fibres, non-substantive to such dyes, may be present, e.g. wool, polyesters, polyamides, cellulosics and neutral or basic acrylics, and the dyebath may contain a dyestuff substantive to these fibres. The acrylic fibres may contain up to 15% of a neutral monomer. At least 80% of the fibre content may be acrylonitrile, the acidic and/or basic component preferably not exceeding 15%. Fibres P may be made by spinning a polymer of acrylonitrile containing an acid monomer, e.g. Na allylsulphonate or K p-styrene sulphonate, and optionally a neutral monomer, e.g. vinyl acetate or methyl acrylate. The acid groups may alternatively be derived from an acid polymerization initiator. Fibres Q are made by blending P with a basic acrylonitrile polymer containing vinyl acetate and either N,N-dimethylaminoethyl acrylate, 1-vinyl-3-methyl-imidazolium chloride or 2.methyl.5-vinyl-pyridinium methosulphate.

Patent ES-439626-A1 (ES)
Title: Process for removing and recovering precipitation agents from precipitate containing proteinous substances
IPC: C02F1/58
Filed: 1975-07-22
Abstract: An alkaline earth metal compound is added to the sludge in a sufficient quantity to bind the proteins. Generally, the pH is then already greater than 6.5, otherwise it is adjusted to above 6.5 by addition of an alkali metal hydroxide or an alkaline earth metal hydroxide. The sludge is then heated to a temperature which is above the coagulation point of the proteins present, a water phase being released which is separated off. This water phase contains the precipitant and can be reused for precipitating proteins. The advantage of the process described here is that not only is a concentration or thickening of the precipitated protein-containing sludge achieved, but also the precipitant is recovered for further use.

Title: Degassing apparatus for use with a dialyzer
IPC: A61M1/16
Filed: 1975-10-21
Abstract: In artificial kidneys, the dialysis solution pressure in the dialyser is stabilised to a value in the range between -500 and +200 mmHg and the flow rate of the dialysis solution is stabilised to a value in the range between 300 and 1000 ml/min. The pressure and the flow velocity of the dialysis solution in the dialyser (48) are controlled by the low pressure regulator (40) arranged upstream, the flow meter (66) arranged downstream and the pump (74) arranged further downstream. The arrangement of the flow meter (66) between the dialyser (48) and the pump (74) arranged downstream prevents the pump (74) from counteracting the low pressure regulator (40) by generating a low pressure in the dialyser (48). The control is preferably carried out only by the setting of the flow meter (66) arranged downstream. The flow meter (66) is arranged upstream with reference to a branch (70), at which branch (70) a degassing line (78) is connected to the line (68) containing the used dialysis solution. As a result, control is made possible of the flow velocity through the dialyser (48) independently of the degassing apparatus (26).

Title: Shaving apparatus
IPC: B26B19/42
Filed: 1979-09-14
Abstract: The disclosure relates to a shaving apparatus having a shear plate with hair entry apertures and a drivable cutting unit with at least one cutting element provided with a cutting edge. Owing to the presence of the shear plate a shaving apparatus of this type does not allow the hairs to be shaved as closely to the skin as a shaving apparatus without such a shear plate, where the cutting element is in direct contact with the skin. In order to eliminate this drawback a construction is proposed in which the cutting element is provided with a hair pulling element which leads in the direction of the driving and which is immobile relative to the cutting element.
