In apparatus in which a container is connected to a source of vacuum in order to draw liquid into the container and in which the vacuum connection is closed by a valve actuated in dependence on the volume of liquid in the container, a second valve is disposed in series with the first, which second valve closes in the event that the first valve is prevented from closing. In one embodiment Fig.1 (not shown) the first valve is actuated by a float and the second valve is a ball float which is enclosed in the releasable connection to the vacuum source and is seatable on the end of the vacuum pipe. As shown in Fig. 3 the second .valve 43 is disposed in an auxiliary container 46 which is attached by a quick release mechanism to the main container 1. The first valve 36 is a ball float seatable on the end of pipe 39 which discharges at an angle into the container 46. The walls of the container 46 may be transparent.

Bottles on a conveyer belt 11, (moving from left to right, Fig. 1) are transferred to a test station 20 by a rotatory carrier moving in 45‹ steps. Opposite the test station the bottle (still mounted in the carrier) is spring urged against rollers 31 in the inspection head, and rotated by a driven roller engaging the bottom of the bottle, Fig. 2 (not shown). The inspection head comprises a rectangular metal box Fig. 3, having antenna 48, 49, opposite windows 46, 47, in the box, and energized from an R. F. generator to establish an electric field through a bottle held against rollers 31.

Abstract: 1,186,760. Riveting. MASSEY-FERGUSONPERKINS Ltd. 12 Nov., 1968 [2 Dec., 1967], No. 54916/67. Heading B3U. [Also in Division F2] The underface of the head of a rivet has an annular recess 5 of which the radially innermost face is the peripheral wall of the shank, and the head has a central, flat, upper face 6 of smaller area than the overall cross-sectional area of the head, so that after the rivet has been placed in a clearance hole and its tail end upset so that the shank is a fit in said hole, pressure may be applied to the flat face of the head to press more of the shank into the hole, so that the shank forms an interference fit in the hole. The flat face is preferably circular and of the same diameter as the shank, and the head is preferably chamfered at 7. The rivet may be of 0À35 to 0À45% carbon steel and have a Brinell Hardness Number of 197 to 241. The hole 8 in the workpiece may be enlarged at the tail end to form a recess 12 into which the tail is upset by anvil 14. The head is then pressed with anvil 13, with or without anvil 14 in position, to press more of the shank into the hole.

Title: Photographic copying of transparencies
IPC: G03D5/04
Filed: 1970-12-02
Abstract: 1336320 Masking transparencies; controlling contrast and gradation EASTMAN KODAK CO 2 Dec 1970 [2 Dec 1969] 57224/70 Headings G2A and G2C A method of masking a photographic transparency in preparation for photographic copying of the transparency comprises securing the transparency to one side of a photographic masking film that is coated with light-sensitive emulsion only on its side remote from the transparency, exposing the light-sensitive emulsion through the transparency and the masking film and developing, washing and drying the emulsion whilst maintaining the transparency is register therewith. In an apparatus for carrying out this method the masking film 21 with transparencies D spaced along its length is intermittently advanced, by a clamp 62, from a loading station 30, through an exposure station 40 and processing stations 50 to a receptacle 100. The loading station 30 receives masking film 21 from a roll 22 and transparencies D from a cassette 10. The transparencies are positioned and their mounts pressed into engagement with adhesive layers 71 provided along the edges of the film. This maintains the transparency and film in registry as they advance. At the exposure station 40 the lightsensitive emulsion is exposed through the transparency and masking film to give a latent black and white image. At 51 a nozzle 511 distributes a layer of developing agent over the exposed emulsion. The emulsion is then rinsed at 52 by an idler roller 523 partly immersed in water, the excess water being removed at 53 by idler rollers 533. At a drying station 54 dry air is blown on to the emulsion from enclosures 541, the moisture laden air being extracted by an outer enclosure 542 and ducts 5421. The masking film is finally cut between each transparency into discrete units by a cutter 55. A safety device 557 comprises two photo-electric cells 5571 and 5572 which are energized and not energized respectively when the transparency is correctly positioned prior to cutting. After cutting the transparencies, which are in registry with an unsharp black and white negative in the masking film, are ready for photographic copying. In an alternative embodiment, Fig. 2 (not shown), the clamp 62 and cutter 55 are omitted. Immediately after the emulsion has been dried the transparency is copied in a printer (80). The transparency is then separated from the masking film, the latter being rewound on to a takeup roll (84). Also, to prevent the adhesive 71 on adjacent layers of unexposed film sticking together a web of silicone paper (24) may be interwound between the film layers on roll 22, the silicone paper winding on to a takeup roll (25) prior to the masking film entering the loading station. In a further embodiment, Fig.3, the layers of adhesive are omitted, the film 21 and transparency D being held in registry by rollers 72 biased towards rails 73.

Abstract: 1333117 Valves DANFOSS AS 16 Dec 1970 [16 Dec 1969] 59751/70 Heading F2V A pressure-regulating and cut-off valve arrangement for controlling the flow of fuel oil from a pump to a burner comprises, an inlet 3, Fig. 1, passages 5 and 7 leading to a reservoir, an outlet 9 leading to the burner, a setting piston 12 permanently acted upon by a spring 17, a further spring 18 which acts upon the displaced piston to increase the gradient of the loading characteristic, and a regulating piston comprising a first member 14 and a second member 15 which seats against an "0"-ring 11 to close the outlet to the burner. A restriction 36 leads to a chamber 34 which is closed by a plate 19 and "0"-ring 35. The position of the spring 18 relative to the setting piston 12 is adjustable by means of a screw 20 and a nut 24. When the pump is started up, oil entering the chamber 16 displaces the setting piston 12 to the right and into contact with the spring 18, whilst the regulating piston remains stationary. With increasing pressure, the setting piston is displaced further to the right until eventually (see Fig. 2) oil begins to flow through the groove 31, the port 27, the passage 28 and the port 29 into the chamber 30. The pressure in this chamber displaces both the members 14 and 15 of the regulating piston simultaneously to the right to open the outlet 9 and also to uncover the passage 5 so as to maintain a constant pressure at the outlet. Meanwhile oil seeps into the chamber 34 through the restriction 36. When the pump is switched off, the setting piston 12 is returned by the action of springs 17 and 18. This movement is transmitted to the member 15 of the regulating piston through the agency of the oil trapped in the chamber 34, and the member is rapidly displaced relative to the other member 14 so as to shut off the outlet 9. The increased pressure in the chamber 30, caused by the return of the member 15, is relieved by further displacement of the member 14 to the right. The arrangement is eventually returned to its initial position by the action of the spring 17 only. The upper and lower parts of the Figures illustrate manufacturing tolerances.
