Abstract: 1,221,352. Laminating process; forms of wood. LUNN LAMINATES Inc. 16 Feb., 1968 [17 Feb., 1967], No. 7732/68. Headings B5L and B5N. A method of making a flat elongated sandwich panel comprises applying a release agent e.g. wax to one face of a flexible sheet 10 e.g. of stainless steel, coating said one face with a gel coat 20 and winding the sheet into a coil, positioning two such coils in spaced aligned relation to one another, so that upon unwinding said coils, the flexible sheet material from one coil will be arranged in spaced parallel relation to the sheet material from the other coil and the coated surfaces of the sheets oppose one another, applying a laminating resin coating to the coated face of one of said flexible sheets prior to depositing on said coated face a plurality of flat core members 52 e.g. of end grain balsa or plywood in abutting relationship and applying a laminating resin coating to the faces of said core members prior to the engagement of said other flexible sheet with said core members, applying pressure to at least one of said flexible sheets for retaining the coated faces thereof in engagement with the core members and maintaining said pressure during at least partial curing of said coating material, and removing the flexible sheets from the panel. An epoxy or unsaturated polyester resin may be used both as the gel coat and as the laminating resin. In a preferred embodiment, a reinforcing fabric e.g. of glass fibres is applied to the gel coat prior to winding the flexible sheet into a coil. An apparatus for use in the method comprises a moulding table surface 42, a pair of channel members 34 positioned on opposite sides of the table surface, a carrying member 38 mounted on said channel members in spaced relation to said table surface for movement thereover, a pair of coils A and B of the gel coat bearing flexible sheet material positioned on said carrying member in spaced relation to one another, means 54 for supporting on said carrying member intermediate said coils a plurality of flat core members 52, means for moving said carrying member along said channel members contemporaneous with the unwinding of said coils in the same direction to arrange the coated faces of said coils in spaced parallel relation to one another and to position the flexible sheet material from one of said coils upon the table surface, means for moving said core members from said carrying member and positioning them in abutting engagement with one another between the coated faces of said flexible sheet material, means e.g. rollers 46 and 48 on said carrying member for applying a resin coating between the coated face of each sheet of flexible material and respective surfaces of each core member, means e.g. roller 60 for applying pressure to the assembly for maintaining the surfaces of said sheets in engagement with the surfaces of said core members.

[Class 38 (v).] A snap - action switch comprises a leafspring 12 of the form shown in Fig. 2 supported at one end in cantilever fashion by a screw 16. The spring is formed with side arms 20 21 which are crimped at 210 and have the free ends fulcrumed at 23 in the ends of a U-shaped member 14 between the limbs of which the spring 12 is free to move. The free end of spring 12 is provided with a heavy contact bar 22 free to move between fixed stops 24, 25, either or both of which may be contacts. On depressing a plunger 15, the left hand part of spring 12 is depressed until it moves across the pivots 23 when the limbs 20, 21, acting in compression, cause the contact 22 to snap downwards. On release of plunger 15 the spring 12 returns due to its own resiliency.

Abstract: 327,550. Siemens Bros. & Co., Ltd., Peters, C. L., and Christian, D. A. March 13, 1929. Automatic exchange systems.- In a system in which a hunting switch has access to a group of trunks via a non-homing non- numerical switch and group-control arrangements associated with the trunks mark engaged idle non- numerical switches if all the trunks of a group are busy, group-engaged contacts are provided on the switches and are normally marked busv but in the event that the last free trunk is taken into use during hunting of a switch, the contacts are marked idle to bring the switch to rest and thereby prevent useless hunting. Busy-tone may be connected to the calling line over the group-engaged contacts, the tone remaining connected until the calling subscriber clears. The non- numerical switches are arranged in panels, a relay G being provided for each panel, and a relay GJ common to the trunks accessible from the same multiple for each row in a panel. In addition to the usual speaking and test wipers W1, W2, W3 of a switch, additional wipers w4, w5 are provided, each bank having an independent groupengaged contact at one end. Normal operation. A preceding hunting switch tests in over wire c and wipers w5, and stepping magnet DM operates to advance the wipers until the speaking wires are switched through and line relay L operates to prevent further stepping and apply temporary busy marking. If the selected trunk is busy the switch is stepped on to find a free outlet over a circuit 6. w3, w4 when the absence of busy marking at contact b allows operation of relay K to prevent further stepping and switch through the a, b wire and effect the release of line relay L. Relay K holds over wipers w4, w3 and contact b. Group-control arrangements. In the event that the last free trunk is seized after the switch commences hunting, relay GJ operates consequent upon operation of contacts e associated with all the trunks of a group. Relay GJ operates relay G which removes earth from the groupengaged contacts of wiper w3 so that when the wiper reaches that contact, the short-circuit across relay K is removed and the switch is brought to rest. A busy signal is given over wiper w1 and remains until the subscriber clears, when relay L, which remains held over wipers w1, 'w2 releases relay K and closes a further stepping circuit over wiper w5. If relay G is still operated, the busy earth on the next contact is fed back over wipers w3, w4 and contacts of relays G, L to the incoming test wire to prevent the switch being picked up.

Title: Improvements relating to the seaming or heat-sealing of plies of thermoplastic film
IPC: B29C65/18
Filed: 1942-06-17
Abstract: 557,574. Seaming non-metallic materials: sealing bags. WINGFOOT CORPORATION. June 17, 1942, No. 8303. Convention date, Jan. 14. [Class 42 (i)] [Also in Group XVII] Two or more plies of thermoplastic material are sealed by heat, the seam or seal formed by coalescence between the plies being reduced in thickness during coalescence and the surface thereof sloping gradually into the surface of the unreduced part of the material ; the sealed area may taper off at one or both sides and the sealing may be accomplished by a heated element having a sloping heated surface or by a heated element that is cooler at the edges than at the middle or other edge, or an element combining the sloping surface and the non-uniform temperature may be used. As shown in Fig. 1, the plies are sealed by a jaw 1 pivoted to a support carrying a fixed jaw 2 of resilient material. The jaw 1 comprises an electrically-heated aluminium blade 6 and a block 7 of a material of low heat conductivity, e.g. an asbestos-cement moulded product, the undersurface of the block being shaped so that the bottom of the blade 6 and the portion 8 of the block form a plane parallel to the surface of the jaw 2 when the jaws are brought together while the rest of the bottom of the block slopes away from the portion 8 and terminates in a tip 9 which does not engage the jaw 2. The two plies 10, 11, Fig. 7, placed between the jaws are united by heat and pressure, a depression 13 formed by the block 7 gradually blending at one side into the top surface of the film while an abrupt wall 15 is formed near the edges of the films by the blade 6; in uniting the two plies of a bag the wall 15 would be at the edges of the bag. Since the blade 6 is heated, the temperature of the block 7 is graduated, a notch 18 aiding radiation and lowering the temperature of the tip 9, so that a difference of at least 100‹F. and preferably 250‹F. is obtained between the temperatures of the blade 6 and tip 9 ; consequently the jaws need not slope away from one another. The block 7 may have an extension projecting under the blade so that the latter does not contact with the films, a block may be fixed to each side of the blade, or the heated element may be an aluminium roller flanked on one or both sides by discs of low heat conductivity which have sloping peripheries ; the two latter forms may be used for sealing the centre seam of a bag.

Increased pressure and a temperature gradient may be maintained in the reaction vessel. Activators, such as HC1 or water may be added. Specification 556,894 is referred to.
