Title: Improvements in apparatus for delivering liquids in measured quantities
IPC: G01F11/16
Filed: 1927-07-22
Abstract: 298,707. Enock & Co., Ltd., A. G., and Enock, E. C. July 22, 1927. Moving-chamber apparatus. - In apparatus for delivering a measured volume of liquid, for example in milk - bottling machines, of the kind in which an open container, normally submerged in the liquid, is raised above the level of the liquid so as to open a discharge valve or outlet, the container 9 slides upon a fixed pillar 1 and is secured to a member 3 passing down inside the pillar and projecting below the lower end thereof. The container is secured to a sleeve 6 sliding upon the pillar 1 and connected to the inner tube 3, the lower end of which carries a sleeve 5 formed with discharge orifices 18. The bottle &c. is pressed upwards against a rubber washer 23 and first raises the sleeve 5 so as to open the discharge 18. When the sleeve 5 contacts with a stop 16, the tube 3 and container 9 are also raised against the pressure of a spring 12, until ports 10 in the sleeve 6 register with ports in, or with the upper edge of, the pillar 1. The tube 3 forms an air vent for disposing of froth. Liquid adhering to the passages after discharge collects in the ports 18; or if the sleeve 5 is secured to the tube 3, a groove or recess is provided to collect this liquid. The container is provided with a cover 19 to prevent " humping up " of the liquid at the centre of the container as it rises. The cover 19 has openings 20 for the admission of liquid, and is formed with beaded edges 21 which prevent the liquid on top of the cover from flowing into the container.

Title: A control device adjustable by means of a photo-electric cell and a moving coil system
IPC: G03B7/12
Filed: 1954-07-05
Abstract: 771,490. Photographic cameras. HERTERICH, W. July 5, 1954 [July 3, 1953; April 5, 1954], No. 19574/54. Class 98(1) [Also in Group XL(b)] In apparatus for setting automatically the aperture or speed ring of a camera or exposure meter in accordance with light intensity, a toothed scanning member co-operates with the pointer of the photo-electrically actuated instrument so that when one of the teeth engages the pointer the motion of the scanning member is changed until a sedond row of teeth engages a tooth freeing the pointer and preventing further movement of the scanning ring.. As shown (Fig. 1) the speed ring of a camera coupled to a guide ring is to be set in accordance with the intensity of incident light. A photo-electric cell (not shown) positions the moving coil of a meter having a magnet 11. To position the speed ring it is moved clockwise against the action of a tension spring 4 by means of a lug 3 carrying with it the toothed scanning ring 6. When the lug is released, ring 2 and scanning ring 6 return until one of a series of teeth 7 engages the upturned end of the instrument pointer. The scanning ring now rotates about pivot pin 5 until one of a second row of teeth 8 engages a fixed pawl 12 which disengages the first set of teeth from the instrument pointer stopping the scanning ring which in turn stops the speed ring thus determining its setting. To allow for aperture position and film sensitivity the instrument magnet 11 with ratchet 12 may be rotated about the arms of tube 1 by rotating lever 3 if a tooth of set 8 is locked with ratchet 12. The magnet carries a notched plate 16 (Fig. 3) the notches corresponding to film speed, in which the nose 15 of a lever 14 coupled to a further lever 20 engages. A pin 21 on lever 20 moves outwardly during this rotation of the magnet so that a spring 24 is able to rotate the aperture ring until a cam 19 carried by the aperture ring engages pin 21. Lever 3 may be coupled with the shutter release. Fig. 5 shows an exposure meter in which the scanning member 6 is carried by a pin which moves up and down with a slide 25 carried on the meter. The slide is moved to one end of its travel by finger operated plunger 3 and lever 31 and the release lever then travels upwards until the scanning member locks when one of a number of sets of correspoinding aperture and speed values on the slide is visible through an aperture. The Specification also describes cameras (Fig. 8 and 9) not shown in which a scanning element of similar construction to that of Fig. 5 is positioned by levers to adjust through a connecting rod (Fig. 8, not shown) or gearing, (Fig. 9, not shown) the camera aperture.

Abstract: 627,173. Tanks. PLANTERS ENGINEERING CO., Ltd., and SCHOFIELD, J. July 24, 1947, No. 19976. [Class 69 (i)] A coagulating tank is characterized in that the sides, ends and base thereof each comprise a single sheet of hollow-moulded plastic material so that joints exist only along the lines of intersection of the sides, ends and base, the edge of one of the two sheets meeting at each such joint abutting against the surface of the other sheet and receiving between its surface webs a strip of material secured to the said surface, the sheets being secured together by screws or equivalent means inserted from the outer side of the tank, so that the inner surfaces are completely smooth. In the form shown, at each of the joints a strip of material 19, e.g. hardwood, is secured to the surface of the sheet 17 which forms one of the meeting faces of the joint, the said strip 19 fitting and being secured between the surface webs 10 and 11 of the sheet 21, the edge of which forms the other meeting face of the joint. Strips 18 of material, e.g. hardwood, are mounted between the webs of each sheet 17, along the edges at which the surface of the said sheet forms a meeting face of a joint. The end sheets 21 have their lower and side edges engaging the faces of the base 13 and side sheets 17, and the other webs 10 extend over the edges of the said sheets 13 and 17. The ribs 12 are cut short at the edges of all the sheets to allow room for the hardwood strips, the strips 14 being secured in the sheet 13 by means of adhesive. Screws project through the strips 15 and 16 into the strips 14, also through the webs 10 of the walls 17 into the strips 16, through the strips 19 into the strips 18 and through the webs 10 of the sheets 21 into the strips 14 and 18 or into the strips 15 and 19. A drain hole 25 is provided in the base sheet closable by a stopper. The upper edges of the sheets 17 and 21 are capped by strips of material such as 24, e.g. hardwood, secured to their edges, said strips having an upper part of a thickness at least equal to that of the sheets 17 and 21 and a lower portion fitting between the webs 10 and 11. They are secured by an adhesive. Division plates are spaced by downward projections on bars located between supports secured to rim strips at the ends of the tank.

[Class 91] Lubricants resistant to high pressure are made by treating a substantially non-paraffinic solvent extract concentrate of a petroleum oil with a sulphurizing agent and blending the product with a lubricating oil of fatty or mineral character. The solvent extract may be sulphurized by heating to 300-375‹ F. with free sulphur for a time sufficient to dissolve the sulphur, and then rapidly chilling to below 250‹ F. to prevent further reactions. The chilling may be effected by adding cold lubricating oil to the hot sulphurized concentrate. The blend of oil and sulphurized solvent extract may be further heated with a sulphurizing agent. The fatty oils specified are lard, sperm, and rapeseed oils. Sulphurizing agents specified are sulphur, sulphur mono- or di-chloride, a mixture of hydrogen sulphide and sulphur dioxide, phosphorus triajid pentasulphide. The solvent for extracting the non- paraffinic concentrate may be phenol, cresol, dichloroethyl ether, aniline, sulphur dioxide, nitrobenzene, furfurol, &c.
