IPC: C06F1/20
Abstract: 383,820. Making match splints. BRUGGER, J., Frutigen, Switzerland. Feb. 16, 1932, No. 4608. Convention date, Feb. 20, 1931. [Class 31 (i).] Guillotine machines.-Match cards are made from a web of wood veneer longitudinally advanced through a machine in which the web is successively impregnated to prevent glowing of the embers, dried, and stamped to form the splints and sheets after which the non-headed material is delivered to further working stages. A number, e.g. 12, of webs B of wet wood unwound from supply rolls V pass through an impregnating tank J followed by a drying chamber K at the end of which the stamping tools are arranged. The webs are fed to the stamping tools by ribbed rolls 30 to which is imparted a step-by-step rotation after each downstroke of the blades by a ratchet wheel and pawl operated by a cam disc on the main shaft. A counter-roll 31 is pressed upwardly by a spring 49 against the underside of each web through an aperture 40a in a bearing plate 40 to which are secured guide ribs 51 between the webs and guide tongues 52 extending under the feed roll. The stamping tools 39, 41, a pair for each web, are carried in separate tool holders 34a, 34b adjustably secured to a crosspiece 33 which is reciprocated within a vertical slot in side shields of the machine frame by connecting-rods actuated by eccentrics on the main shaft. The blade 39 slits the web into match stems at the end of its stroke, the tool 41, which projects below it, having meantime punched out a triangular portion to form pointed tips for the heads. A triangular recess 53b in a guide member 53 co-operates with the punch which is pressed into it by a leaf spring 42. In front of the bearing plate 40, a guideplate 54 carries ribs 55a between which a blade 59 is reciprocated for severing a completed match card. The blade holder 57 is pivotally mounted on a pin 59 in a transverse tilting member 60 extending across the machine and is pressed against the plate 54 by a spring 62 hooked on an extension 58a of the blade holder sleeve 58. The tilting member is rocked by a lever actuated by a cam disc which completes a revolution when the stamping tools have performed ten strokes. The match cards pass into separate chambers of a transmission drum longitudinally divided into twelve sections and rotated step by step by ratchet mechanism in conformity with the movement of the severing blade. The Specification as open to inspection under Sect. 91 described the match cards as of wood by way of example only. This subjectmatter does not appear in the Specification as accepted.

Title: Microporous sheet structures
IPC: C08J9/28
Filed: 1971-08-20
Abstract: 1360672 Coating processes CARL FREIDENBERG 20 Aug 1971 [22 Aug 1970] 39218/ 71 Heading B2E [Also in Division C3] A process of preparing a microporous sheet on a support by coagulation comprises forming a solution in a solvent of a polyurethane prepolymer obtained by reacting a first active hydrogen containing component having a molecular weight above 400 with a polyisocyanate and reacting this prepolymer in the solution with second active hydrogen containing component having a molecular weight less than 400 and a polyisocyanate, the total amount of second active hydrogen containing component and polyisocyanate that reacts with the prepolymer being from 20 to 40% by weight of the prepolymer, to form a final polymer which is insoluble or only slightly soluble in the solvent, spreading the solution during reaction as a layer on a support and removing the solvent. Suitable first active hydrogen containing components are polyester polyols, polyether polyols, polycaprolactam polycaprolactones and polycarbonates; examples of polyesters being decarboxylic acids and glycols or glycol mixtures. The isocyanates used to form the prepolmer may include 4,4'-diphenylmethane diisocyanate, 1,5 naphthalene diisocyanate, 1,4- phenylene diisocyanate, tolylene diisocyanate, tolylene diisocyanate, xylylene diisocyanate, isiphorone diisocyanate, hexamethylene diisocyanate, 4,4'-dicyclohexylmethyne diisocyanate, or mixtures thereof. The molar ration of polyol to diisocyanate is 2:1 or from 1:1.2 to 1:2, and the prepolymer is formed at elevated temperatures, for example for 10 minutes at 130‹C. Additional isocyanate added to the prepolymer solution includes those described above and the second active hydrogen containing component is predominantly difunctional but may contain a few percent trifunction compounds. Suitable difunctional compounds are diols and diamines, for example butan-1, 4-diol, propane-1,2-diol, propane-1,3-diol and ethylene glycol. To accelerate reaction of prepolymer with the isocyanate and active hydrogen containing reagents catalysts such as triethylene diamine, dibutyl tin dilaurate and tin dioctoate are uses. Suitable supports include glass sheet or paper from either of which the microporous coating sheet is stripped, or a non-woven fibre structure to which the coating sheet may adhere. The reacting solution of final polymer and precursors may be sandwiched between two films to provide a gas permeable bond therebetween and the solution may contain conventional additions such as mineral fillers, pigments, dyes, silicones and emulsifiers. The amount of second active hydrogen containing component and polyisocyanate is preferably 20 to 40% by wt. of the amount of prepolymer. The amount of solvent is preferably from 15 to 50% by wt. of the reaction constituents. Three specific examples are given.

Abstract: 1365869 Conveyers; suction carriers EMHART CORP 14 Feb 1973 [30 March 1972] 7273/73 Headings B8A and B8H Bottles from a glassware forming machine (not shown) are deposited in groups of twelve on a conveyer 12 from which they are transferred to a lehr conveyer 14 by a carriage 22 having a plurality of vacuum pick-up heads 20. The carriage comprises a parallel-crank linkage 34, 36, 38, 40 of which the upper horizontal link 34 is supported on rails 30, 32 movable transversely to the conveyer 12. An electric motor 42 actuates the rails and a pneumatic motor 46 rotates crank arms 36, 38. Each pick up head 20 is connected to a common manifold 54 which, via channels 66 and a cavity 68, is connected to a bottle support member 70 adapted for pneumatically sealed engagement with a bottle. For controlling the vacuum within the head 20 a flapper valve 82 opens or closes the channels 66 and has actuating rods 90, 92 which, when the valve is closed, are engageable by a bottle received by the head. The provision of the valves permits the capacity of the vacuum source to be reduced. After a group of bottles has been deposited on the conveyer 14, the crank arxs 36, 38 are swung almost horizontal so that the carriage 22 is able to clear the next group of bottles on the conveyer 12. The rails 30, 32 are then retracted and the carriage is ready to perform the next cycle. The operation may be modified to enable bottles to be transferred from conveyer 14 to conveyer 12. If it is desired to selectively reject or by-pass bottles, a solenoid 150 is energized to cause the valve 82 to remain closed and a bottle, instead of being picked up, is merely pushed off the conveyer 12 into a shoot between the two conveyers. The sequence of operations is normally controlled by air valves 104, 112 and by cam means 118, 120 driven by the motor 42. The bottle support members 70 may be interchangeable to receive different shaped bottles and the heads 20 may have members for guiding the bottles into position against the members 70.
