Title: Improvements in or relating to flexible epoxy resins
IPC: C08L63/00
Filed: 1963-06-25
Abstract: Flexible epoxy resins are obtained by reacting a mixture of (a) a polyepoxide having at least two epoxy groups per molecule and (b) a component comprising a mixture of an at least trihydric polyol and at least one dicarboxylic acid anhydride in a proportion such that the ratio of carboxyl equivalent to hydroxyl equivalent is at least 2, the polyol being at least 50% esterified with the anhydride or anhydrides to form a monomeric acid ester containing at least one aliphatic chain of at least four carbon atoms, the ratio of the total carboxyl equivalents to the epoxy groups being at least 1.5 and not greater than 2.  When the aliphatic chain is derived from the polyol it may include one or more ester or ether linkages.  In the preferred embodiment the pure monomeric ester is mixed with additional anhydride to form component (b).  Component (b) may also comprise a tertiary amine. The curable compositions are useful as casting, layering, potting and impregnating resins and as coating compositions and adhesives.

Title: Improvements in or relating to temperature regulating devices
IPC: G05D23/275
Filed: 1945-09-28
Abstract: 606,436. Automatic control systems for air heating devices. HANNAH, S. H. Sept. 28, 1945, No. 25252. [Class 38 (iv)] In an air or other fluid temperature regulating system, electric heaters are cumulatively switched into or out of circuit, at a controlled rate, by a switching device associated with a single temperature responsive device. At the commencement of the heating process, the minimum temperature contacts 1 of the thermometer will be closed, the switch SS is in the extreme clockwise position, as shown. On closing the start button STB the main contactor coil M and relay TRR are energized, thus energizing the main heater MH, which is continuously in circuit and a relay, HR, whereby all the subsidiary regulating contacts are operated so that all the auxiliary heaters RH1 &c. are initially employed. On the air temperatures rising to the predetermined upper limit, the thermometer arm 3 makes at contact 2, the high temperature relay TRL and the solenoid LS are energized, the latter with D.C. from the rectifier R. The relay coil HR is de-energized, the contacts IHR, IHR, &c. are opened, but the coils HI, H2, &c. remain energized through contacts H11, H21, &c. which comprise a differential system effecting a reduction in the tendency of the system to heat. The switch SS is rotated in an anticlockwise direction, by the solenoid LS, thereby cutting out auxiliary heaters by interruption of the subsidiary contacts H6 &c. at a rate set by an adjustable time-lag fitted to solenoid LS, until the relay TRL opens. Continuous back and forward movement of the switch S, under the control of the switch arm 3 maintains the system air temperature between the limits. Upon completion of the work, the stop button SPB is pressed and all heater circuits are broken. A circuit, through contact 18 of switch SS contacts SSR1, SSR11 to the rectifier R remains closed and the relay RS is energized and rotates SS to the extreme clockwise position, wherein the contacts SSR1 are separated and the system is completely deenergized. In alternative arrangements, the selector switch may be operated by an electric motor and the heaters switched direct from the switch itself.

Title: Machine for applying binding strips to boxes or other hollow objects
IPC: B31B17/00
Filed: 1929-08-21
Abstract: 338,227. Soc. Anon. Parfumerie Houbigant. June 21, 1929, [Convention date]. Affixing tape and like strips.-Relates to a machine for applying binding strips of paper, tissue, or the like around boxes or other hollow articles. The article to which the strip is to be applied is mounted on a mandrel 3, Fig. 2, capable of being given a rolling motion in the direction of the arrow g<1> over a length f of the binding material, coated with adhesive, spread or exposed on a support 1. At the end of the movement, the mandrel, which can rotate in one direction only, is raised from the support and given a return movement during which it drags out a fresh length of the binding material, this movement ceasing in the position shown in Fig. 5 with the severing by tension at the point f<2> of the binding strip which has been weakened at a previous stage by the action of a cutter 24. In the actual construction of the machine, shown in Fig. 6, the mandrel, carried by a lever 6, manually or otherwise operated, has a pinion 8 adapted to engage a rack 9 on the machine bed to effect the forward movement, at the end of which the mandrel is raised by meeting a ramp 10, the pinion then becoming disengaged from the rack. To permit this raising of the pinion, the bearing 11 of lever 6 is mounted on a second lever 12 which is caused to rise against spring action by the movement of a notched cam 15 actuated by a spring-controlled stop lever 17. In the normal position, lever 6 engages a projection 18 on lever 17 and maintains it depressed. The mandrel carrying the partially wrapped box thus raised from the support is now returned towards the starting position, dragging with it a fresh supply of the binding material for wrapping the next box. Shortly before the end of the movement, the cutter 24, mounted on a short lever 26 actuated by a rod 28 from shaft 6, is pressed against the strip to hold and incidentally weaken it. The movement continues with the breaking of the binding strip as explained above, the lever 6 meanwhile striking the rod 17-18 causing the cams 15 to be re-set to lower the bearing 11 and bring the pinion 8 back into engagement with the rack. Guide members 33, Fig. 11, urged upwardly by springs, may be provided to control the movement of the strip over the support, and parts such as 38, 39 which may be appropriately recessed, are provided to effect the turning-in of the binding strip over the edges of the box parts. These members are attached to the support by spring-controlled bolts. The machine is shown as provided with means for glueing the strip, which passes from a spool 47 over rollers 49, Fig. 8, and partly round a glueing cylinder 50 intermittently rotated by ratchet mechanism deriving motion from the lever 6 through a crank 54. The strip is turned through 180‹ between the counterpoise 57 and the cutter, to bring the glued side uppermost.
