Patent GB-1087164-A (GB)
Title: Improvements in or relating to toggle circuits
Inventor: FISHER BRIAN
IPC: H04Q3/00
Filed: 1965-04-08
Abstract: 1,087,164. Automatic exchange equipment. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. March 15, 1966 [April 8, 1965], No. 14863/65. Heading H4K. A lock-out circuit, for selecting one out of a number of routes indicated by a mark on one out of as many input leads, comprises a bistable circuit for each input such that a " one " input produces a " nought " output, the existence of a " one " input to any one circuit producing a " nought " input to all other circuits which inputs over-ride any subsequently occurring " one " inputs and in consequence lock those other inputs out. In such an arrangement each circuit is required to provide an input lead to all other circuits and when the number of circuits is large this produces an undesirably large number of inputs to each circuit. The invention reduces the number of inputs by arranging circuits in groups such that, if any circuit in a group produces a " nought " output, lock out signals are delivered over one lead to each other group and not over leads to all other circuits. The bi-stable circuits may be transistor circuits or may be circuits of electromagnetic relays. Differences in reaction time discriminate between coincident input markings but an order of priority may exist within the groups.

Title: Recovery of indene by azeotropic purification with furfural
IPC: C07C7/06
Filed: 1957-05-10
Abstract: Indene is recovered from mixtures of hydrocarbons containing indene by subjecting the mixtures to azeotropic distillation using furfural as the azeotropic former to remove non-indene constituents in the form of other azeotropes and recovering indene of enhanced purity. The feed mixture may be an oil obtained by fractional distillation of coal tar oils, water gas oils, drip oils which contain in addition to indene, benzene, styrene, ethyl benzene, trimethyl benzene, methyl pyridines, benzonitrile, coumarone, or methyl coumarone.  In a preferred embodiment 80 parts of a coal tar naphtha fraction having a boiling range of 135-189 DEG  C. is mixed with 120 parts of furfural and distilled in a 100 plate Podbielniak column at atmospheric pressure.  A single treatment gave a recovery of 75 per cent of the indene originally present, the product consisting of 90-95 per cent of indene.  By reprocessing the small fractions of indenecontaining material boiling immediately below and above the heart cut of indene the recovery can be increased to 85-95 per cent with a purity of 90-95 per cent.  Distillation is normally at atmospheric pressure but may be at subatmospheric or superatmospheric pressure.

Title: A loom stop motion
IPC: D03D51/00
Filed: 1944-08-17
Abstract: 592,535. Looms. PILLING, T., and PILLING & SONS, Ltd., J. Aug. 17, 1944, No. 15720. [Class 142 (i)] A loom stop-motion for use in conjunction with a centre weft fork of the hit and miss type such, for example, as described in Specification 558,321, has an upright slide D, Fig. 2, mounted on the sley A and operatively connected to a horizontal slide C connected by a rod C' with the supplementary slide (not shown) appertaining to the centre weft fork. When the weftfails or breaks, the slide D remains down and, when the sley comes forward, the lower end of this slide rocks an adjustable pivoted spring- controlled lever E carrying a finger E<2> which strikes an arm H on the shaft H', oscillation of which causes the cam H' carried thereon to disengage the starting handle J thereby transferring the belt from the fast to the loose pulley. The handle J carries a slip catch actuator K<3> having a gap inclined along one side through which passes one arm K<2> of a two armed lever pivoted on the lever E, the other arm K<1> engaging a stud L on one arm L<1> of a pivoted brake catch lever, the other arm L<3> of which engages an adjustable collar M on the spring controlled brake adjusting rod M<1>. Actuation of the lever E as above described also causes the arm K' to release the brake catch lever from the collar M whereupon the spring M<6> applies the band brake M<5> to stop the loom before the sley reaches the front centre. As the starting handle moves to the off position, the inclined side of the gap in the actuator K' depresses the arm K<2> and lifts the arm K<1> clear of the stud L so as to allow the catch L' to fall on the collar M and be in a position to re-engage the latter when the brake is released. The slip catch K' automatically re-engages the stud L when the starting handle is returned to the on position. The brake may be released by a hand or foot lever. In a modification the slide D may be held stationary in a raised position as long as weft is presented to the weft fork and, in the absence of weft, be lowered to actuate the lever E.

Title: Process for the purification of hydrogen peroxide solutions
IPC: C01B15/013
Filed: 1930-05-26
Abstract: Solutions of hydrogen peroxide are purified or stabilized by an electro-osmotic treatment which may be carried out in a similar manner to the known electro-osmotic process for purifying water. This treatment removes impurities such as salts, acids, colloidal substances and catalysts giving rise to decomposition of hydrogen peroxide.  The purified solutions may be concentrated by evaporation or distillation.  The apparatus may comprise a plurality of cells connected in series, each cell being divided up into a cathodic, anodic and central compartment by means of two ceramic diaphragms stable to hydrogen peroxide.  The hydrogen peroxide solution is passed through the central compartments whilst water traverses the other compartments.  According to one example a hydrogen peroxide solution containing sodium chloride and sodium phosphate was freed entirely from chlorine ions by passage through this apparatus.  In another example the treatment almost completely freed a hydrogen peroxide solution from sulphate ions.
