Title: Stacking device for metal plates
Inventor: GRANDMONTAGNE WALTER
IPC: B65H29/36
Filed: 1968-04-25
Abstract: 1,218,259. Stacking sheets; conveyers. MOELLER & NEUMANN G.m.b.H. 25 April, 1968, No. 19685/68. Headings B8A and B8R. A device for stacking metal sheets carried on a roller conveyer comprises a movable transfer device including support rollers for the sheets rolling on a fixed guide rail for a first part of the movement of the transfer device to initiate delivery motion of a sheet being stacked, the support rollers rotating freely after leaving the guide rail to allow the sheet to travel onward to the stacking position. General arrangement (Fig. 1, not shown).- Metal sheets 13 carried on a roller conveyer are delivered by a transfer device (2) to a stacking box (3) arranged at one side of the conveyer and provided with a fixed stop (4) and an adjustable stop (5) for receiving sheets of varying widths. The transfer device (2) comprises support rollers 8 mounted on carrier arms 7 and riding on relatively fixed guide rails 9 for a part of their travel. Each guide rail 9 is pivoted about supports (10), (11) remote from the stacking box, and can pass between the rollers (1) of the conveyer. Thus, in operation, the guide rails 9 and carrier arms 7 are initially below the plane of the conveyer, and are then pivoted under the action of hydraulic unit (12) so that the rollers 8 engage a sheet 13; an endless cable 15 is then driven to advance the carrier arm 7 towards the stacking box, the rollers 8 riding on guide rails 9 and thereby moving the sheet 13 at twice the speed of the arms 7. The rollers 8 at the right-hand end, as seen in Fig. 4, of the carrier arms travel past the ends of guide rails 9, and rotate freely on support strips 7b in the carrier arms, the rollers being allowed a measure of vertical displacement. The drive to cable 15 is then cut off, and the momentum of sheet 13 is sufficient to deliver it against stop (5) where it drops under gravity into stacking box (3) when the drive to cable 15 is reversed. Transfer device details (Fig. 4).-The loaded carrier arms are prevented from pivoting with respect to the guide rails 9 by means of rollers 25, 26 riding in channel members 9a, (9b), Fig. 5, (not shown), of the rails 9. The vertical play in the support rollers 8 is provided by a roller link chain 8a, (8b) secured under tension to the carrier arms 7, the chains 8a, (8b) engaging support members 7b on the arms 7. A limit switch (30), Figs. 1 and 3 (not shown), operated by the rear edge of a sheet being delivered, controls the retardation of the carrier arms 7 with respect to the width of the sheets.

Filed: 1947-07-24
Abstract: 646,796. Colorimeters. BOYER, W. J. July 24, 1947, No. 19965. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 1, 1948.] [Class 40 (iii)] A colorimeter used for determining the proportion of a particular constituent in a solution by measuring the absorbtion of the characteristic wavelength of the constituent comprises a lamp 11 surrounded by a water-jacket 12 for cooling purposes, having in it windows to permit the passage of light to the exterior of the jacket. The water-jacket is itself surrounded by a rotatable filter carrier 13 carrying a number of filters 13D so spaced that each is aligned with a window although one filter only is in use. This ensures that all filters are at the same temperature and in thermal equilibrium. The liquid under test is placed in a tube 17 and light passes through the tube to a photo-cell 16. The output of the photo-cell may be measured on a potentiometer, a suitable circuit for which appeared in Fig. 2 (not shown), of the drawings in the Specification as open to inspection under Sect. 91. The transmissivity of the liquid is read on the potentiometer and this is related to the light density of the particular constituent. The percentage of the constituent is then determined from a graph. The particular application of the invention is to analysing various metals and the Specification as open to inspection contained examples of methods of preparing the test liquid from the alloys while cancelled. Figs. 5A, 5B and 5C (not shown), give examples of graphs into which the potentiometer readings may be interpolated to indicate the percentages of the constituents. This subject-matter does not appear in the Specification as accepted.

Filed: 1960-06-09
Abstract: 905,127. Protective arrangements. STANDARD TELEPHONES & CABLES Ltd. June 9, 1960, No. 20250/60. Class 38 (5). An arrangement for protecting a circuit, e.g. a railway signalling circuit, from a fault condition which is represented by a current which is greater or less than a predetermined value, comprises a balanced relay X having one winding A connected in series with the circuit D.S. and an opposing winding B through which a current of the predetermined value is passed so that the relay X only operates when the current in the circuit D.S. varies from the predetermined value. In operation assuming no fault exists, control relays (not shown) close contacts a 1 , a 2  to cause current to flow through a delay relay V and the windings A, B. Relay X is balanced and does not operate so that when relay V closes its contacts v relay W is energized. Relay W completes a holding circuit for itself at w 1 , changes over contacts w 2  to prepare a circuit for relay Y and closes contacts W 3  to connect an impedance ZA to the winding A. The relay X is now unbalanced and changes over contacts x to complete the circuit for relay Y, which now completes a holding circuit for itself at contacts y 1  and at contacts y 2  connects a supply directly to the circuit D.S. If, however, a fault existed when the action is initiated, relay X is unbalanced and changes over contacts x before relay V operates. Thus, when relay V closes its contacts v, a warning device I is operated through contacts v, x and w 2  and no further action occurs as relays W and Y are not energized.
