Title: Improvements in or relating to envelope making machines
IPC: B31B19/00
Filed: 1953-08-31
Abstract: An applicator for applying a pressure-sensitive adhesive, e.g latex, to envelopes made in a rotary machine, comprises a rotor having a series of arcuate, adhesive-applying members which are successively movable through an applying station, and a pair of co-operating envelope-conveyer belts so arranged that envelopes fed thereto with the surfaces to be coated facing upwards, are carried in inverted position at the adhesive-applying station, and are delivered from the applicator with the adhesive-bearing surfaces facing upwards.  The invention is described as applied to a rotary envelope-making machine as described in U.S.A. Specification 1,774,536 and in which the envelopes are advanced continuously by rollers 2 driven by a common longitudinal countershaft, coated with gum on the sealing flaps, and delivered to a drying wheel 8, which may be as described in U.S.A. Specification 1,834,567.  A conventional gumming mechanism comprising a gum pan 9, pick-up roller 10, transfer-roller 11 and applicator roller 12 is provided for use as an alternative to the device of the invention.  This comprises a belt 40 which is trained around pulleys or rollers 29, 34, 48, 49, 30 and 51, and a belt 41 which passes around pulleys or rollers 31, 37, 38, 36, 32, 39 and 45.  The belts have parallel runs 42, 46; 47, 43 and 50, 44, which co-operate to carry envelopes presented by the rollers 2 over the rollers 34, thence in inverted position to the roller 36, and finally deliver them to the conveyer belt 25 for presentation to the drying drum 8. While the envelopes are inverted, strips of latex are applied by applicators such as 59, which are adjustably mounted on the shaft 58. Each applicator comprises a hub 61 from which extend legs 63 carrying arcuate shoes 64, which move through latex in the receptacle 57 and carry a film of latex past a scraper and gauging mechanism 66 which includes an adjustable scraper blade and side <PICT:0744512/III/1> <PICT:0744512/III/2> scrapers such as 78.  The remaining film of latex is then applied to the envelopes which are gripped between the belt runs 43, 47 by pressure devices 93, 94 comprising spring-urged rollers 97, 98 acting on the belts.  The portions of the envelope to which latex is applied are supported by a pivoted spring-urged platen 105 having its position adjustable by a set-screw 107.  When the machine is in operation the applicator shaft 58 is driven in timed relation with the rollers 2 by a chain-and-sprocket drive connected to their common driveshaft; when the machine is stopped, it may continue to be driven, but at a lower speed, by a separate motor and chain drive, the sprockets on the shaft 58 incorporating an over-running mechanism.

Abstract: 513,146. Raw materials for lacquers. I.G. FARBENINDUSTRIE AKT.-GES. Aug. 15, 1938, Nos. 24061 and 24062. Convention dates, Aug. 14, 1937, and Jan. 25,1938. [Class 2 (iii)] Chlorinating products which are suitable lacquer raw materials are made by chlorinating polymeric butadiene hydrocarbons of low viscosity which have been prepared by effecting the emulsion polymerization of the butadiene hydrocarbons in the presence of regulating agents which effect an increase of plasticity and solubility of the product or by subjecting a polymeric butadiene hydrocarbon prepared by emulsion polymerization to adisaggregation process. Other polymerizable substances such as styrene may be polymerized along with the butadiene. Suitable regulating agents are described in Specification 387,363 and 512,479, and French Specification 686,934, particularly diisoprophylxanthogen disulphide and ditolyl disulphide. The disaggregation can-be effected by a treatment with asymmetric derivatives of hydrazine such as phenylhydrazine or by an oxidizing treatment at an elevated temperature in the presence of anti-oxidents as described in Specification 513,116. In examples, butadiene and diisoprophylxanthogen disulphide in sodium oleate solution containing ammonium persulphate and chlorinated. The product is stabilized by treatment with dilute sodium carbonate solution and adding phenoxypropene oxide. A mixture of butadiene and styrene is emulsified in the same way with sodium diisobutyl naphthalene sulphonate. An emulsion polymerizate of butadiene and styrene is disaggregated by heating as described in Specification 513,116, dissolved in chloroform and chlorinated. A polymeric butadiene is disaggregated by the action of phenylhydrazine dissolved in chlorobenzene and chlorinated, Specification 495,085 also is referred to.

Filed: 1977-06-09
Abstract: 1536387 Transistor circuits INTERNATIONAL BUSINESS MACHINES CORP 9 June 1977 [30 June 1976] 24252/77 Heading H3T A sense amplifier latching circuit comprises transistors T1, T2, T3, impedance means T4, T5, and unidirectional conductors T6, T7 connected substantially as shown, VH and MS being bias terminals, B0, B1 being input terminals and A, B being output terminals. As embodied in a memory array, Fig. 2, the circuit is operated to sense the state of bit lines B0, B1 by applying a memory select pulse to MS to turn on transistor T3, bringing the coupled source electrodes of T1, T2 to earth potential. If, e.g., B0 is at a slightly lower potential than Bl, point A is brought down more than B, and this initiates the latch, T2 turning fully off. At this time T6 is reverse biased so that no current is drawn from B0. It is stated that, since the change in potential of B0 during sensing is small, the circuit is fast and consumes little power.

A switch 10 has a printedcircuit board 14 with three gallium arsenide diodes, a coloured filter 16 and a diffusing plate 17. Alternatively a single diode may be mounted on a printed circuit 141. A fault detecting circuit uses luminous constructions 23 which comprise three lightemitting diodes 15 forming a pilot lamp 20, a transistor 22 whose base is connected to a fixed potentiometer formed by Zener diode 26 and a resistance 27 and resistances 24, 25 which control the intensity of light from the diodes by coupled switches 75, 76. When a fault occurs, relay 28, preferably a reed switch, switches the diodes 15 on in pilot lamp 20 and the fault signal is also fed through resistance 60 and diode 61 to a switching stage 50 and a delay unit 40. After a delay, relay 35 is closed and the multivibrator 30 activated thus flashing the main warning lamp 21. The main warning lamp 21 does not flash if the fault lasts only a short time. When the signal of the main warning lamp 21 has been recognized it may be switched off by closing switch 70 or 71. This activates the thyristor 63 thus blocking the fault signal coming through resistance 60. (For Figures see next page.)
