Means for applying wax or a wax-carbon composition to a surface of a web of material comprises a heated bath for containing molten wax, a driven and heated cylinder having a broken surface, a doctor blade for engagement with the surface of the cylinder, to reduce wax picked up by the cylinders from the bath substantially to that which is present in the recesses of the broken surface, a second cylinder having a resilient surface or surface parts for direct peripheral contact with the first cylinder, a third driven and heated cylinder adapted to impress the web against the resiliently surfaced cylinder so that wax is transferred from the resilient surface or surface parts on to the web and means for cooling the wax which has been applied to the web. By the term " cylinder having a broken surface " is meant a cylinder having in at least a part of its curved surface a multiplicity of recesses distributed between 3000 and 20,000 per square inch which may be furnished by machining or etching. As shown, the apparatus comprises a heated bath 3 of wax, a driven cylinder 4 peripherally immersed in the bath and having interior heating means and having its surface broken, a doctor blade 6 bearing on cylinder 4, a second cylinder 7 having a resilient peripheral covering and a third cylinder 14, cylinder 7 bearing against cylinders 4 and 14. A web of material is drawn from feed-roll 21, over idle roller 22, through the nip between rollers 7 and 14 and thence over chilling roller 18 which has internal cooling means. The web then passes over idle roller 19 and is wound up on roller 20. The resilient covering on roller 7 may be of rubber. A " one time " carbon paper, coated wholly or in panels, may thus be made with a very thin wax-carbon film.

Abstract: 818,261. Reciprocating pumps. JOSEPHS, D. P. H. Nov. 30, 1956 [Dec. 2, 1955], No. 34525/55. Class 102(1). A pump, for dispensing herbicidal liquids, comprises a tubular member 1, an end cap 3 and a dished shape member 6 forming a reservoir 9 and a pumping chamber 8. A piston 10, urged downwards by spring 11, carries a piston rod 5 which extends through a cylindrical boss 12 of the cap 3.

On releasing the member 1 which moves upwards, liquid is forced by the piston 10 through passage 14, forced by the narrow portion 13 of the rod 5, and is discharged through the orifices 17. A seal 18 is attached to the lower side of the piston 10 to prevent leakage of the liquid when the pump is not in use.

Title: Improvements in or relating to maximum demand mechanisms, particularly for electricity meters
IPC: G01R11/60
Filed: 1961-09-26
Abstract: 922,366. Maximum demand meters. LANDIS & GYR A.G. Sept. 26, 1961 [Oct. 24' 1960], No. 34538/61. Class 106 (3). [Also in Group XXIV] In maximum demand mechanism wherein the maximum value indicated by a driven indicator drum 9 is cumulatively transferred to an additional maximum demand counter 22, the spindle 12 of the drum 9 is connected to the spindle 20 of the counter 22 through a one-way rotary coupling 19. The coupling 19 comprises a friction disc 25 on a shaft 18 and a carrier 26 on the spindle 20, a spring 27 mounted on the carrier 26 bearing on the periphery of the disc 25. While the drum 9 is advancing to indicate maximum demand its spindle 12 drives through racks 14, 16 and pinions 13, 17, the shaft 18 of the disc 25 and slipping recurs in the couple 19 because a brake 28 applies a greater frictional drag on the spindle 20 than does the spring 27 on the disc 25. When, at the end of a registering period, an operator moves the racks 14, 16 in the opposite direction, the drum 9 is turned back to zero while the counter 22 is advanced by the same amount through the coupling 19 because in this direction the friction between the disc 25 and spring 27 overcomes that of the brake 28. In the embodiment of Figs. 4-6 (not shown), the maximum demand drum 9 is replaced by a pointer whose spindle bears the spring carrier 26 of the coupling 19 while a bushing is formed in one with both the friction disc 25 and a bevel gear for driving the counter spindle 20. In the embodiment of Figs. 7, 8, the brake 28 comprises a lever 43 pivoted on the transfer spindle 44 of the counter 22 with one arm 45 urged by a spring 46 against a brake disc 47 on the counter spindle 20. Should the pointer 35 be moved back against its zero stop with undue force a stop 33 on its shaft 34 will act through stops 8, 41 on a cog wheel 40 on the arm 42 of the brake lever 43 causing the arm 45 to apply a consequential force to the brake disc 47 and will thus prevent the counter 22 from being advanced too far. By reversing the action of the friction coupling, the transfer from the maximum demand indicator to the additional indicator can be spread throughout the metering period.
