Title: Improvements in or relating to interpolymers of vinyl aromatic compounds with compounds containing unsaturated fatty acid radicals
IPC: C08G59/16
Filed: 1954-04-22
Abstract: A vinyl aromatic compound is polymerized with an unsaturated fatty oil acid before, during or after esterification of the acid with a resin produced by reaction of a bisphenol-aldehyde condensate with epihalohydrin or a homologue thereof.  The resins and the fatty acid esters thereof are described in Specification 749,218.  Suitable vinyl aromatic compounds are styrene or vinyl toluene.  The products may be vehicles for clear or pigmented coating compositions of the baking or air drying type without a curing catalyst.  Esterification is preferably carried out in presence of a solvent.  In the example, styrene and linseed oil fatty acids were interpolymerized in presence of a sulphur dioxide-benzidine redox catalyst.  The product was added to a bis-phenol-aldehyde epoxide resin in three portions at 350 DEG , 350 DEG  and 440 DEG  F.  The mass was blown with CO2 and the temperature raised to 420 DEG  F. and then to 470 DEG  F.  The product diluted with xylene and with cobalt naphthenate drier formed films.  Specification 611,109 also is referred to.

Title: Improvements in or relating to metal-working presses
IPC: B21D45/00
Filed: 1938-04-19
Abstract: 513,854. Metal-working presses; stamping. GLASNER, R. W. April 19, 1938, No. 11673. [Class 83 (iv)] - ' Unwinding.-A metal working press-is fed with strip metal from an uncoiler and the stamped out workpiece 55 is lifted by magnet 56 in the top die until conveying-away belts 33 are automatically moved underneath, whereupon ejectors 57 drop the work piece on to the belts which carry it away, and then move bodily out of position, to allow the next stamping out of a fresh piece. The coil rests on inter-geared driven rollers 62, Fig. 11, and is gripped by end plates 61, Fig. 9, moved axially by hand-turned pinion and rack on their shafts 78. The coil is rotated by the rollers 62 driven by an electric motor through hydraulic variable speed gear 70, and a reducing gear by means' of chains 73 &c. and the strip metal is fed into the press by a pair of feed rollers 89 which draw it through a straightener 88. The feed is stopped and started by a hand lever 90 separating or closing the rollers 89. If the rollers 62 uncoil too fast the loop 91, so formed, operates a limit switch 93 to stop the motor driving the rollers 62. The limit switch 93 can be adjusted and swung to any required position by moving it along its pivotable carrying arms (95, Fig. 10 not shown). The moving in and. out of the conveyer belts 33 .between the dies is done as in Fig. 4 by the rise of the press head, a rod 35 on which carrying a nut 47 which lifts an adjustable trunnion 45 whereby levers 39, 40, 41 move a slide 34 inwards to move the conveyer belts between the dies to receive the work piece. Descent of the die allows a spring 48 to pull back the slide 34 and move the conveyer belts 33 back out of the way. The belts 33 are driven by a motor 50 by long' splined shafts 53 which allow for the sliding in and out of the conveyer belt frames. The height of the inner top die 27 is adjustable by nut 25, Fig. 4. Specification 513,936 is referred to.

Title: Process for the improvement of the hardening characteristics of unmodified phenol formaldehyde resins
IPC: C08G8/28
Filed: 1952-05-08
Abstract: Metal-containing synthetic resins as described in Specifications 718,283 or 718,284 are used as hardening agents for unmodified phenol-formaldehyde resins.  The addition may be made before or after the phenolic resin has been diluted or worked up for use as a lacquer, adhesive or similar product.  In the examples, a resin from aluminium butylate and acetoacetic ester was added (1) and (2) as a toluene solution to an ethyl alcohol solution of a phenol resol or a novolac; (3) to a phenol formaldehyde resin, the mixture after dilution yielding a baking lacquer.  In example 4 a resin from aluminium butylate and diethyl malonate was added to a phenol resol; (5) a resin from aluminium chloride and acetoacetic ester is added to a phenol resol; (6) a resin from ferric butylate and acetoacetic ester in toluene was added to a phenol formaldehyde resin.  The products are hardenable at lower temperatures or with shorter times than the products without the additions.  Specification 734,677 also is referred to.

In an embodiment a sleeve 9, Fig. 3, with circumferential grooves 10 and a bore larger than that required for the tip is inserted in the initially swaged end 7 of a blowpipe tube, a mandrel 11 is inserted in the sleeve and by circumferentially applied compressive swaging the tube metal is forced into the grooves 10 and the sleeve bore is forced into contact with the mandrel. In a modification, Fig. 4, the sleeve bore is initially formed to the required final dimension. Circumferential beads may be provided on the sleeve instead of grooves and the end of the blowpipe tube may be counterbored to receive the sleeve.

Title: Improvements in or relating to the starting and synchronising of alternating currentdynamo-electric machines
IPC: H02J3/42
Filed: 1925-05-09
Abstract: 256,335. Reyrolle & Co., Ltd., A., and Burgess, W. A. A. May 9, 1925. Synchronizing dynamo-electric machines.-A polarized or biassed relay responsive to the slow beat between the periodicities of supply and machine voltage alters the field so as to bring the machine into synchronism at the correct polarity- This relay may be damped, e.g. by dash-pot, magnetic brake or air vane, or separate damping means may be inserted in its circuit, e.g. a transformer or choke arranged to pass operating current when of slow frequency only or a separate relay responsive only to slow frequency beats.. The methods of altering the field include shortcircuiting a resistance in the field circuit, closing an open field circuit, reversing or re-grouping the field or exciter field connections and inserting an auxiliary voltage in the field or exciter circuit such as that of a booster or storage battery. A simple arrangement for a synchronous induction motor is shown in Fig. 2 the relav D, damped bv a short-circuited winding D<2> and connected' across the exciting winding B<2>, of the motor, the stator of which is shown at B. closes the circuit of a polarized relay C when the beats are slow whereupon the latter relay short-circuits a resistance B<5> in the circuit of an exciter B<4> when the polarity of the beat is correct and of sufficient amplitude. Instead of or in addition to shortcircuiting the resistance B<5> the relay C may operate a switch B<6> to insert the exciter into the field circuit. Arrangements are described in which the relay C closes the circuit of a contactor which inserts a storage battery or a series booster into the field circuit of a rotary converter. An arrangement for a tap-started rotary converter H is shown in Fig. 5. When the beats at the armature brushes have attained a slow periodicity and sufficient amplitude the primary J<1> of a short circuited transformer allows enough current to pass to energize a relay J which closes the circuit of the polarity relay K. Under the required conditions this relay then reverses the field connections at K<1>, K<2>, makes an alternative circuit for its own coil at K<4> and de-energizes the relay J at K<3>. A circuit is also closed at K<5> for a voltage relay L which when full voltage becomes established on the converter armature energizes a conductor L<2> to render the field circuit independent of the reversing switch K<1>, K<2> at L<4>, L<5>, to apply full transformer voltage to the armature at L<3> and to de-energize the polarity relay at L<6>. The Specification also describes arrangements for starting six-phase rotary converters with starting motors having tapped windings in series with the converter armature, the automatic control circuits being energized in one case from the alternating current supply mains and in the other from the direct current terminals of the converter. The polarized relay may be energized by beats induced in the field circuit.
