Abstract: 1,036,321. Continuous furnaces; cooling furnace charges. BABCOCK & WILCOX Ltd. Feb. 21, 1964 [Feb. 21, 1963], No. 7134/63. Heading F4B. Heat exchange between discrete solid material and an elastic fluid, e.g. cooling fuel briquettes, is carried out in an enclosed passageway through which open topped containers with bottoms pervious to the fluid are conveyed on a trackway, sealing means above and below the containers being spaced to define a sinuous fluid path from the fluid inlet and outlet at opposite ends of the passageway. Each container 14 is filled from a shoot 39 at one end of a tunnel through which it is carried by skids resting on rails at the sides of the tunnel. An automatic weighing device actuates the driving ram 73 when the container 14 is filled, and a leveller 79 arranges the charge. Slipper seals 46, 47, 45 engaging the containers constrains an inert gas to take a sinuous path 67 from the inlet 49 to the outlet 51, and by making the seals at least as long as a container, the briquettes remain untreated for short heat equalizing intervals. At the end of the tunnel, each container enters a cage and is inverted with it to discharge the briquettes into a water seal 18. The containers 14 are transferred to a side by side return conveyer whence they are transferred through water seal 17 to the loading position. In another embodiment the return conveyer carries partly cooled briquettes through a water bath in a tunnel below the cooling chamber to a discharge position near the loading point. In this embodiment, the inert gas is cooled by water sprays in the lower tunnel, and the containers have hinged bottoms to allow them to be emptied without inversion. The transfer mechanisms are described.

Filed: 1941-06-11
Abstract: 549,394. Transfer devices for conveyers. HARBER, L. S., and BAKER PERKINS, Ltd. June 11, 1941, No. 7400. [Class 78 (i)] A transfer means for transposing articles from the delivery end of one chain or band conveyer to the receiving end of another like conveyer moving in the opposite direction comprises, in the case of two conveyers located one above the other, a tiltable platform 16 automatically actuated by the weight of the articles being transposed. Fig. 1 shows baking tins 12, strapped together in groups, brought by a double-chain conveyer 10 in succession under a changing shoot 15, the filled tins passing over rubber &c. covered rollers 40 on to the up-tilted platform 16. The foremost tin strikes against a detent finger 19, so releasing the platform to allow it to tip, due to the weight of the tins and against the bias of a spring or of a counter-weight 16a, to the downtilted position, in which the tins slide off the platform on to receiving rollers 40 on the lower return conveyer 11. The pivoted finger 19 is counterweighted at 20 and is positioned by an adjusting screw 24. The upper conveyer 10 may travel stepwise to maintain the tins stationary during the filling interval, or, alternatively, the conveyer chains may move continuously, and the empty tins held up by a finger 26 pivoted to an adjustable lever 30 so as to keep the foremost empty tin under the shoot 15, the chains then sliding under the empty tins and carrying the filled tins forward toward the platform 16. The finger is pressed up by a spring 31, and is lowered at predetermined intervals to allow the filled tin to proceed by an arm 33 rocked by a cam, &c. from the main drive. When transposition is required from a feeding conveyer to a return conveyer located in the same horizontal plane, a rotary disc may be located at the ends of the conveyers. The disc is continuously driven from the main power source, and stationary or band guides steer the tins off one conveyer and on to the other. Alternatively a cam-rocked arm may push the filled tin laterally over a ridge from one conveyer to the other.

Title: Improvements in single station rangefinders with variable base and method of compensating adjustment errors
IPC: G01C3/24
Filed: 1938-03-10
Abstract: 491,706. Range -finders. ZEISS, C., [Firm of]. March 10, 1938, No. 7443. Convention date, March 23, 1937. [Class 97 (i)] In a single-observer range-finder with a variable base, adjustment errors are compensated by measuring the range with a definite parallactic angle at the target and repeating the measurement with another definite parallactic angle, the actual range, free from adjustment errors, being proportional to the difference between the base lengths in the two measurements. In the form shown, the parallax in the second measurement is zero. A telescope 1 is rigidly secured to a housing 7 and to a guide 8, the housing containing a triangular reflecting- prism 9 covering the whole aperture of the objective 2, and a pentagonal prism 10 which covers the upper half of the said aperture. A wedge prism 12, the height of which corresponds to the vertical diameter of the objective 2 is mounted on the housing 7 so as to deviate the entering rays in the plane of measurement. Mounted on the guide 8 is a slide 14 carrying a pentagonal prism 15 which covers the lower half of the objective. The slide 14 also has a pointer 17 co-operating with a range scale 13 on the guide 8. The exit pupils of the upper and lower halves of the objective 2 are caused to overlap by a bi-prism 18, and a diaphragm 5 is provided, the aperture 6 of which corresponds to the overlapping parts of the said pupils. The observer thus sees two images separated by a sharp line viz the ridge of the bi-prism. In use the slide 14 is displaced until the two images coincide and the position of the pointer 17 is read. The slide is now moved until the prism 15 lies below the prism 10 so that the rays entering both prisms are deviated by the prism 12 and the parallactic angle at the target is therefore zero, and a second reading is taken when the images again coincide. The actual range is represented by the difference between the two readings. In another form, in which the two parallax angles are numerically equal, the prisms 10, 12 are mounted to slide on a guide parallel to that on which the prism 15 is mounted and the prism 12 can be rotated about the axis of the entering ray pencil through 180‹. In the first measurement the prisms 10, 15 occupy the positions shown in Fig. 1, and for the second measurement they are moved along their respective slides so as to exchange positions and the prism 12 is rotated through 180‹ so as to reverse the direction of the deviation which it produces.
