Title: Improvements relating to sheet delivery mechanism for printing presses
IPC: B65H39/07
Filed: 1931-07-06
Abstract: 387,362. Sheet-delivery apparatus. HEWITT, A., 25, Field Street, King's Cross Road, London. July 6, 1931, No. 19480. [Classes 100 (i) and 100 (ii).] A sheet-delivery mechanism for printing- machines, adapted to hold the sheets separate and out of contact with one another for a sufficient time to dry the impressions, comprises a series of platforms arranged in vertical sets which move alternately away from a position of vertical coincidence, the sheets being prevented from participating in the reciprocating movements so that they drop from platform to platform in a substantially vertical path to the delivery tray. As shown, two sets of platforms are employed comprising two series of horizontal rods b<1>, c<1> respectively. The rods b<1> are fixed to vertical bars b<3> mounted on a transverse member b<2> forming part of a carriage b reciprocated on rollers b<4> along rails a<2> on the supporting frame a. A similar carriage c running on rails a<3> carries vertical bars c<3> on which the rods c<1> are mounted. The carriages are reciprocated alternately from a shaft e by link mechanism j, k respectively, and as one carriage, e.g. b moves from the superposed position, Fig. 1, the sheets carried thereby are caused by the bars c<3> to drop on to the rods c<1>, and on the reciprocation of the carriage c, the sheets drop on to the rods b<1> and so on until the sheets reach the tray d. In a modified form, the bars b<3>, c<3> are replaced by short depending stops on the rods b<1>, c<1>, and the sets of rods are connected at each end by horizontal bars. The shaft e drives a shaft g carrying a semicircular gear g<1> and a disc g<2> which for the part g<3> of its circumference opposite to the teeth of the gear g<1> is of greater circumference than the gear g<1>. The gear g<1> imparts one revolution to shafts h<1>, il alternately, through gear wheels h, i on the shafts, which are half its size. Discs h<2>, i<2> on the shafts h, i have arc-shaped recesses h<3>, i<3> alternately engaged by the part g<3> of the disc g<2> so as to prevent movement of one disc while the shaft carrying the other is being rotated. A tooth g<4> on the gear g<1> engages a similar tooth h<4>, i4 on the shafts h<1>, i<1> alternately to start the rotation of the shafts. The link mechanisms j, k are pivoted to crank-discs h<5>, i<5> on the shafts h<1>, i<1>. The sheets delivered from the printing machine by tapes l are received by a platform b<5> on the carriage b as the latter moves to the right, Fig. 1, and a stop o limits the travel of the sheet. A stop m<1>, which held in a horizontal position during the reception of the sheet, drops to a vertical position to prevent backward movement of the sheet as the carriage b moves to the left. Stops n<1>, n<2> on the carriage b engage a projection m2 on the spindle m of the stop m<1> to operate the stop and springs m<3> hold the stop in either of its extreme positions.

Title: Improvements in or relating to the manufacture of meta-dichlorobenzene
IPC: C07C17/358
Filed: 1951-08-24
Abstract: A process for producing m-dichlorobenzene or a mixture of dichlorobenzenes enriched in the meta isomer, comprises heating, at a temperature of at least 120 DEG  C., a dichlorobenzene containing or consisting of ortho- or para-isomers or both in the presence of aluminium chloride and water which is present in an amount from 3 to 27 per cent by weight based on the dry weight of the aluminium chloride.  10 to 15 per cent by weight of aluminium chloride is usually effective.  Smaller amounts, e.g. 2 per cent, give smaller conversions to meta-isomer.  During the time of heating to 120 DEG C. at least some of the aluminium chloride reacts with the water to form a basic aluminium chloride and hydrogen chloride.  After the reaction the aluminium chloride may be removed with an alkali or by washing and the product separated by fractional crystallization and distillation.  The starting material may be treated initially to remove impurities having an inhibiting action by heating it with concentrated sulphuric acid or with Friedel-Crafts catalysts, e.g. halides of aluminium, zinc, boron or iron followed by distillation of the dichlorobenzene. Using o - dichlorobenzene (the preferred starting material), some p-isomer is also produced.  Repeated treatments of the same material without separation of the products yields an equilibrium mixture of about 50 per cent of meta-, 25 per cent of ortho- and 25 per cent of para-isomers.  Up to about 1 per cent disproportionation to mono- and trichlorobenzenes occurs.  In examples there are heated to reflux temperature mixtures of aluminium chloride and water (in the ratio 12 : 1) and (1) commercial o-dichlorobenzene; (2) o-dichlorobenzene which has been previously refluxed with anhydrous aluminium chloride; (3) o-dichlorobenzene which has been refluxed with concentrated sulphuric acid; (4) dichlorobenzenes obtained from the residues of the reaction mixture of example (1) and containing about 98 per cent o-and 2 per cent m-isomer; (5) commercial p-dichlorobenzene, to give mixtures containing increased amounts of m-isomer.

Abstract: 1425068 Switching systems for load supply circuits SILEC-SEMI.CONDUCTEURS 27 April 1973 [29 Nov 1972] 20227/73 Heading H2H A static relay for controlling the power supplied to a load 4 from a source Va comprises a main thyristor 1 and an auxiliary thyristor 2, the gate and one of the main electrodes of the main thyristor being connected in parallel with the gate and one of the main electrodes of the auxiliary thyristor so that when a control signal Vi is applied to the main electrodes of the auxiliary thyristor, the main thyristor is switched on only near the zero crossings of the source voltage. The thyristor 2 will only be switched on when its anode-gate voltage is lower in absolute value by at least a voltage Vd than the control voltage Vi. Thus if the control signal is applied during one half cycle of the source voltage Va, the thyristor 2 and therefore the thyristor 1 will not be switched on until the zero crossing of the following negative half-cycle. Modifications are described in which the thyristor 1 is replaced by a triac connected across a bridge rectifier and in which the control signal is supplied from a high-frequency transistor oscillator. A circuit is also described in which the circuit supplying the control signal is isolated from the rest of the circuit by a lamp and photo-cell arrangement.
