Patent GB-118384-A (GB)
Title: An Improved Mechanical Feed to Tinning, Terne Machines and the like.
Inventor: DAVIES EMRYS GORDON
IPC: C23C2/40
Filed: 1918-02-06
Abstract: 118,384. Davies, E. G. Feb. 6. 1918. Pile tables; pusher feeds for single sheets; sheet-separators. -Consists of an improved apparatus for feeding metal plates to tinning, terne, and like machines. The pile of plates is placed on a table A which is reciprocated vertically on guides B by cams D on rotating shafts C driven by gearing from a shaft y. The top sheet is thus raised into contact with rubber or leather suckers h to which it adheres when the table falls. The suckers are carried by a plate H yieldingly supported from a plate I by springs G and guide-rods J. The plate I is fixed to an arm F of a shaft E carrying an arm E<1> which is engaged by an arm E<2> on one of the cam shafts C so as to rock the shaft E and carry the separated sheet into the bite of feedrollers K<1> which pass the sheet up into guides T. The sheet then falls on to guides L, Fig. 4, in a casing m from which it is pushed into the grippers or other forwarding devices of the tinning &c. machine, by forks S adjustably secured to a cross bar Q<1> carried by endless belts n. The ends of the bar Q<1> run in guides on the frame to hold the forks above the guides L during the non-feeding stroke of the forks. An acid bath such as showll in Fig. 3<B> may be arranged between the guides T and the casing m, the sheets being pushed through the acid bath on guides Z<1> and into guides similar to the guides T by rotating pushers Z. The sheets may be fed from two or more piles alternately by providing a number of pile tables and suction separators, the tables being operated by common cam shafts having cams set at different angles.
Patent GB-577869-A (GB)
Title: Improved process for the alkylation of isoparaffins with olefins
IPC: C07C2/62
Filed: 1943-02-09
Abstract: In the continuous alkylation of an isoparaffin with an olefin using a liquid acid catalyst, olefin is added at multiple points to the reaction medium stream, adequate mixing and reaction volume being provided after each point of addition, the proportion of total isoparaffin to total olefin in the fresh feed being approximately 6 : 1, and the amount of recycled catalyst-hydrocarbon emulsion being 5-200 volumes per unit volume of fresh feed of isoparaffin and olefin.  Butene and isobutane are fed through a heat exchanger to the lower of two superposed compartments of a reactor containing recycled emulsion.  The product is withdrawn, mixed with further olefin, and fed to the upper compartment.  The product is recycled, part being withdrawn to a settling tank where acid is separated and recycled, while alkylate is fractionated to separate isobutane for recycling, normal butane, gasoline and heavy alkylate.  In a modification, three separate reactors are used, olefin being fed to the emulsion stream just prior to its entry to each.  Equal amounts of olefin should be added at the several stages.  The isoparaffin is preferably added just ahead of the first mixer although it may be divided into separate feeds for each reactor and fed either separately or with the olefin.  A number of series reactor circuits can be operated in parallel.  The results of a two-stage addition of butene are compared with a single addition process to show the effect in increasing the octane number or increasing the plant capacity while maintaining the product quality.  Ratios of recycled emulsion : fresh feed are 7.5 and 5 : 1.

Vinyl chloride is polymerized or copolymerized in aqueous suspension or emulsion in the presence of a seeding product which provides the only catalyst used, is obtained using a waterinsoluble catalyst, and from which unreacted monomers have been removed. The seeding product is prepared in suspension in the presence of polyvinylalcohol, methylcellulose, carboxycellulose or gelatine to give a product of particle size 20-200 microns and the preparation is repeated as many times as necessary to provide a sufficient amount for the subsequent polymerization. Alternatively it is prepared in suspension in the presence of an alkylarylsulphonate, alkylsulphate or fatty acid salt of an alkali metal optionally with an added fatty alcohol or polyoxyethylene alkylphenol to obtain a product of particle size 0À05-1À5 microns. The catalyst is lauroyl peroxide, tertiary butyl diethylperacetate, diethylhexylpercarbonate or diacetylperoxide. The polymerization is preferably effected continuously passing monomer or monomer mixture, seeding product, water and dispersing agent into a reaction mixture and removing product continuously.
Patent GB-469611-A (GB)
Title: Improvements in or relating to electric relay apparatus
IPC: H01H3/26
Filed: 1936-01-24
Abstract: 469,611. Electromagnetic switches and actuation of switches. GRASEBY, R. C. Jan. 24, 1936, No. 2291. [Class 38 (v)] [Also in Group XXXVIII] A relay apparatus comprises a relay-device connected by supply and pilot wires to a mechanically independent master-switch device which, on closure of its contacts to energize the pilot wire, automatically maintains the said wire energized for a predetermined period, the main contacts or other operative members of the relay-device being actuated by a self-starting electric motor excitable initially from or under the control of the pilot wire and subsequently through auxiliary contacts adapted for being closed and held closed for a predetermined period by the action of the motor so that the latter will continue to run until the end of the last-named period irrespective of the condition of the pilot wire. As shown in the Figure, on closure of a control contact 13 such as by a push-button, time switch, &c., a circuit is completed for a motor 12 which may be of the synchronous clock type. The consequent rotation of the motor shaft causes a cam 15 to engage contacts 14 and complete the motor circuit independently of the push-button &c. so that the motor continues to run until the contacts 14 are opened at the end of a predetermined rotation of the shaft i.e. half a revolution in the construction shown. During this rotation, further contacts 17 in a controlled circuit are operated by a second cam 16 and connect a pilot wire 5 to one of the main conductors 3. During this connection a relay arrangement similar in construction and arrangement to the apparatus previously described is brought into operation and controls by a cam 11 and contacts 6 the connection of a lamp 7 across the mains 3, 4. To ensure the completion of operation of secondary relays such as 1 the period of rotation of the motor 12 of the master relay 2 is made long enough to ensure that it does not come to rest before the motors 8 of all secondary relays. In modified arrangements, the operating contact may be automatically latched in position and tripped mechanically after a predetermined rotation of the motor 12 so that the motor operated relay arrangement may be brought into operation by an electromagnetic relay.
