Filed: 1971-09-28
Abstract: 1363705 Imprinting forms ADDRESSOGRAPH-MULTIGRAPH CORP 28 Sept 1971 [30 Sept 1970] 45208/71 Heading G4T [Also in Division B6] Type-wheel machines.-A machine for printing on forms F comprises a plurality of type wheels P1 to P5 in the surface of a bed 12, and a platen carriage 14 including an impression roller (198, Fig. 8) movable across the bed 12 to effect printing. The machine is of a type similar to that of Specification 1,165,587 and includes means for preventing more than one printing until a resetting lever 24 has been operated to reset all the indexing levers K. The resetting lever 24 supports a bail bar (258, Fig. 3) which co-operates with all the gear segments (48) of the indexing levers K to return them to their starting position. Zero suppression.-The starting or datum position of the hundreds, tens and units indexing levers K1 to K3 correspond to an * on the respective type wheels P1 to P3. A drive pawl 154, Fig. 10, is pivotally mounted on each of the layers K1 and K2 and co-operate with a cam spacer 158 provided on the adjacent indexing lever K2 or K3. When lever K1 is moved from the * position to the digit 1 position, the nose 166 of the drive pawl 154 acts against the lip 172 of the cam spacer 158 thereby rotating the cam spacer which moves index lever K2 attached to the cam spacer via square projection 160. As the cam spacer is being rotated, cam surface 162 of the drive pawl 154 contacts a pin 164 causing the drive pawl to move against the bias of spring 170, so that the nose 166 is moved out of engagement with the lip 172. Further movement of the index lever K1 does not affect index lever K2 which remains in the zero position. Index lever K3 is similarly moved from the * position to the zero position when either of levers K1 or K2 is operated. Limiting the maximum setting.-For the particular embodiment described, an arbitrary setting of 200À00 was chosen. Cam discs 38, Fig. 3, are provided on each of the index setting levers K1 to K5. Control members 124 and 126 co-operate respectively with the cam discs of levers K2 to K5 and K1. Movement of lever K1 to the digit 2 position (200À00) rotates cam disc 38 of lever K1 so that control member 126 pivots in a counter-clockwise direction against bias of spring 140 so that a blocking finger 136 moves into engagement with aligned notches (152, Fig. 15) of the cam discs 38 of levers K2 to K5. These levers are then prevented from being advanced beyond the zero position so that it is impossible to imprint an amount in excess of 200À00. Movement of lever K2 rotates its cam disc 38 so that control member 124 is pivoted in a counter-clockwise direction so that the blocking finger 132 moves into engagement with the notch (146, Fig. 16) in cam disc 38 of lever K1. The width of notch (146) limits the movement of lever K1 to the digit 1 position (100), thereby limiting the amount to 199À99.

Title: Improvements in and relating to polyurethane sponges
IPC: C08F283/00
Filed: 1963-11-28
Abstract: Absorbent polyurethane sponge may be prepared by a process comprising the steps of preparing a mixture containing an organic polyisocyanate, a hydrophilic polymer insoluble in water, an activator, and a polyester or polyether which has had a monomer of hydrophilic character grafted thereon, foaming the mixture and hardening the resultant foam at ambient temperature.  The polyisocyanates are generally aliphatic aromatic, cyclic or heterocyclic diisocyanates, but thioisocyanates may also be used. Suitable hydrophilic polymers are cellulose, cellulose ethers which are insoluble in water, partially hydrolysed or saponified polyvinyl acetates or partially acetalized or esterified polyvinyl alcohol. The activator described is a mixture of a triethylene diamino, water and silicone oil.  Examples of suitable polyesters are reaction products of acetic acid with glycols such as diethylene glycol, triols such as trimethylolpropane or higher polyols; examples of suitable polyethers are reaction products of propylene oxide with glycols or preferably triols such as glycerol, hexanetriol, trimethylolpropane or even higher polyols. The polyesters or polyethers may be grafted by any method such as irradiation or transfer with hydrophilic monomers, but grafting by means of previous ozonization is preferred.  The hydrophilic monomers grafted are of the vinylidenic type and those mentioned are carboxylic acids, anhydrides of carboxylic acids and non-saturated polymerizable amides.  In the examples, acrylamide is grafted on to a polyether obtained from glycerine and propylene oxide and on to a polyester obtained from adipic acid diethylene glycol and trimethylolpropane. A non-grafted polyester and/or polyether may be incorporated in the mixture.
