Title: Improvements in or relating to structural elements made from paper and like sheets
IPC: D21J1/16
Filed: 1946-07-24
Abstract: 628,180. Cellular paper &c. filling for laminated material. MAY, G., and DUFAYCHROMEX, Ltd. July 24, 1946, No. 22086. [Classes 96 and 140] A cellular filling for a double skin structural material is made by applying lines of adhesive such as casein to flexible material such as paper previously impregnated with a thermosetting resin, superimposing the sheets with the adhesive lines 15, 16 staggered in alternate layers, and cutting the adhering flat plies along lines 19 transverse to the adhesive lines into slices which are opened out to produce a cellular structure, Fig. 5. The structure is made rigid by heating to cure the resin. The resin may be phenol- or cresol-aldehyde, spiritsoluble or water-soluble, and may be applied as an aqueous solution to high wet-strength paper. The lines of adhesive are applied after drying the impregnated paper, e.g. as described in Specification 591,772. The final heating of the expanded honeycomb material is effected while it is secured in a frame, hot air being circulated through the honeycomb, e.g. by a fan. The cellular material is secured between laminations, e.g. paper or plywood, either before or after heating to cure the resin. Specifications 613,529 and 3178/40 (as open to inspection under Sect. 91) also are referred to.

Title: Improvements in and relating to electrical connectors and the manufacture thereof
IPC: H01R43/02
Filed: 1932-08-08
Abstract: 405,649. Direct connections between conductors. COOK, C. R., Chesworth, Horsham, Sussex. Aug. 8, 1932, No. 22168. [Class 38 (i).] A terminal such as a socket is formed with a projection enclosing a space to house sufficient solder for the connection of a wire to the terminal. The projection may take the form of a pair of spaced tags 3, Fig. 1, at the base of a socket 4. If the socket is formed from a blank as described in Specification 336,612, [Class 38 (i), Electric couplings &c.], the tags 11, Fig. 8, are formed on the blank 10 and bent down parallel to one another and the parts 10 are bent up and shaped to form the socket. In the case of a turned socket a reduced cylindrical projection at the base is either cut away by three milling cutters leaving the two parallel tags, or the projection may be hollow and have slots, holes, &c. in its wall. The terminals are then dipped in a solder bath, being conveyed by an automatic carrier. Where socket terminals are to be dipped, a carrier 17, Fig. 13, with solid or resilient plugs 19 to carry the sockets 23 rotates above a bath 22 of solder. After dipping, the sockets are cooled by an air blast from a nozzle 24 and are removed from the plugs 19 either by withdrawing the plugs or by a wedge-shaped fork 20. They may fall into a cooling and cleaning bath. The level of solder in the bath 22 is maintained by pellets or drops of solder fed automatically or by hand, or the height of the bath may be adjustable. A valveholder may have the ends of all its sockets dipped in one operation, either by an automatic carrier or by hand. Specification 352,102 is referred to.
Patent GB-651051-A (GB)
Title: Improvements in or relating to thermostatic electric switches for energy input regulators
IPC: H01H37/60
Filed: 1948-08-23
Abstract: 651,051. Thermal switches. THERMEGA, Ltd., SWINDELLS, V. E., and BLACKBURN, J. E. Aug. 23, 1948, No. 22220. [Class 38(v)] A switch of the general construction disclosed in Specification 624,315 is adapted to be adjustable by a cam to serve as an energy-input regulator. An insulating mounting 4 is urged about a pivot 5 by a spring 14 so that a plate 6 thereon presses against a cam 10, and carries a " fixed " contact spring 7 and a movable contact spring 8 having a projection engaged by a '' channel " spring 9 whereby the spring 8 is normally held against its own resilience in contact with the spring 7. The " channel '' spring 9 comprises a strip bowed in the direction of its width and is secured at one end to the mounting 4, the other end normally bearing against a stop formed by a cranked-extension of the plate 6. A crimp 21 in the extension may be extended or compressed to vary the load on the channel spring, and the strain in the spring 8 is adjustable by a screw 19 in the plate 6. A bimetal strip 2 secured to a fixed mounting 1 and heated by a series winding 15, carries a screw 20, which extends through a clearance hole in the extension of plate 6 and engages an insulating button on the spring 9, whereby on heating of the strip 2 the load applied to the spring 9 is increased and the latter collapses, whereupon the spring 8 moves to open the contacts 26, 27. On subsequent cooling of the strip 2 the spring 9 straightens itself and recloses the contacts. The energy passed by the switch is regulated by rotation of the cam 10 associated with an indicator 13, thereby adjusting the distance between the strip 2 and the spring 9. To modify the action of the switch and obtain finer control, an auxiliary series heater 16 is provided which dissipates a predetermined quantity of heat to the strip 2, or, alternatively, the heater 16 may comprise a variable resistance. In Fig. 4 a time/energy curve more nearly approaching a straight iine is obtained, by employing a further bimetal strip 22 which is secured to the pivoted mounting 4 and heated by a winding 23. The winding 23 is initially connected in parallel with the winding 15 through a screw 24 engaging the strip 2, whereby a proportion of the load current is diverted from the winding 15. The bimetal 22 moves upwardly to disconnect the winding 23 at 24, so producing a time-delay before the whole load current flowing through winding 15 causes downward deflection of the strip 2 and opening of the contacts 26, 27. Radiated heat from the winding 15 ensures that contact 24 does not remake before separation of the contacts 26 27. Specifications 585,590 and 624,316 are referred to.
