Title: Improvements in and relating to flushing tanks
IPC: E03D3/10
Filed: 1937-06-28
Abstract: 497,765. Valve-discharge water-wastepreventers. KJAERSGAARD, M. A. June 28, 1937, No. 17966. Convention date, June 27, 1936. [Class 26] In a water-waste-preventer in which a valve returns to its closing- position under the action of gravity or a spring or both and against a resistance ceasing after a predetermined time, the quantity of the discharge is varied by moving the valve predetermined distances from its closing- position. The valve 7 can be moved in a cylinder 5 from a position in which it seats upon the cistern-outlet 4 by one arm 17 of a double-armed lever ; the other arm 18 of the lever is connected to chains 19 fitted with stops 20 coacting with a slotted member 21, whereby the arm 17 and therefore the valve may be moved to the extent required. The descent of the valve is opposed by the partial vacuum which tends to form in the cylinder above it, the amount of such vacuum being controlled by a preferably adjustable aperture 22, or by the fit of the valve in its cylinder or of a one-way closure-valve 11 in the upper part of the cylinder. An aperture 23 in the cylinder-wall serves to break the vacuum after the valve has travelled a certain distance, while apertures 8 in the lower part of the cylinder place the cistern and outlet in communication. The cistern is filled at 12, air escaping by a pipe 13 until the latter is closed by a pivoted float 14, whereafter the supply continues until the pressure in the mains and the cistern become equal.

Title: Apparatus for the liquid treatment (e.g. plating) of workpieces
IPC: B65G49/04
Filed: 1956-06-13
Abstract: 802,596. Step-by-step conveyers; endlesschain conveyers. UDYLITE RESEARCH CORPORATION. June 13, 1956 [Aug. 24, 1955], No. 18228/56. Class 78 (1). In apparatus for the liquid treatment, e.g. electroplating, of workpieces 24 of the kind comprising a series of tanks 21, 22, 23, Fig. 16, through which the workpieces are conveyed, the track sections 34a ... 34d, on which the work carriers 25a, &c. run above the plating tank 22, are relatively movable and can be caused selectively to engage one or more of the carriers while at rest on the top of the tank and to remove them therefrom as the sections are raised. The track sections are carried by a framework which is raised and lowered by chains driven by hydraulically-actuated mechanism. Each pair of track sections, e.g. 34a, Fig. 5, is disposed inwardly of longitudinals 47 of the framework and each section is supported by a pair of arms 55 which are pivoted at 56 to a lower part of the framework. Fingers 66 fast on a motor-driven shaft 63 are provided for moving each of the pairs of track section 34 in timed sequence into engagement with rollers 61 mounted on the work carriers. The framework carries also a track 10, which when the framework is in the upper position, is in alignment with the adjacent track 40. The track 10 is made in sections corresponding to the sections 34a ... 34d and disposed directly above them. Each section is carried by a pair of arms 12 pivoted at 16 to the framework. As any section of the track 34 moves upwards, the arms 55 displace the section of track 10 immediately above it, and the section of track 34 replaces the section of track 10, as shown in Fig. 6. The sections of track 10 may be slidably mounted instead of pivoted. The carriers 25 are moved along the tracks by pivoted pushers 82, 83, Fig. 19, which can swing in one direction only and depend from reciprocating members 79, 81, respectively. In order that a carrier may be retained in a selected position, means is provided for putting out of action a portion of the pushing mechanism. Each pusher carries a pin 89 which co-operates with a guide 88 having a downwardly-curved pivoted extension 91. As a slide moves to the left the pin 89 rides up the part 91 on to the horizontal part of the guide and the pusher is raised, Fig. 22, above the position in which it can engage a carrier and remains inoperative as the slide moves to the right unless an opening 94 in the guide has been uncovered by raising a gate 93. In this case the pin falls through the opening and the pusher engages the carriers. The position of each pair of gates is controlled by the cam-shaft 63 so that they are raised when the corresponding pair of track sections is not actuated to remove a carrier from the tank. In a modification, the pushers are mounted on endless chains.
