Title: Improvements in thermostatic controls for gas burners
IPC: F23N5/04
Filed: 1929-05-10
Abstract: 324,600. Langer, R. March 14, 1929, [Convention date]. No Patent granted (Sealing fee not paid). Thermally-actuated valves.-A safety cut-off gas cock 2 is held in the open position against the action of a spring 7 by a spring-pressed sliding catch 9, released by the contraction of a rod arranged near the burner and acting through a Bowden cable 10. When opening the cock by the handle 6, the Bowden cable is uncoupled from the catch 9 by releasing a second catch 18 to permit the catch 9 to engage a notch in the disc 3 and hold the valve open. As the thermal rod expands, the catch 18 automatically reengages with a notch 17 on the catch 9 under the influence of a spring 21, so that on subsequent cooling the contraction of the thermal rod releases the catch 9 and allows the valve to close.

Abstract: 1478789 Shearing LINDEMANN MASCHINENFABRIK GmbH 11 April 1975 [17 May 1974] 15022/75 Heading B3W A shear for cutting scrap longitudinally and transversely of the feed direction comprises an upper transverse blade in two parts 8 and 9, mounted on holders 6, 7 separately or synchronously movable, e.g. by hydraulic cylinders 13, 14, an upper longitudinal blade 22 mounted on holder 6 and movable in a plane 19 between blade parts 8 and 9 and a lower longitudinal blade 24 mounted on a holder 18 movable between an operative and an inoperative position. A lower fixed transverse blade 15 is provided. The holder 18 constitutes a work support table and is rigidly connected with holder 7 by a tie 21. A work support table 17 is similarly connected to the holder 6. If scrap is to be sheared across the full width b of the shear mouth 2 with no longitudinal cut, the holders 6 and 7 are locked together by, e.g. an hydraulically actuated bolt 10 and as they descend the tables 17 and 18 descend and the blade 24 is moved out of the possible cooperation with blade 22. If scrap is to be cut over half the width b and longitudinally at each stroke, the bolt 10 is disengaged and only holder 6 is lowered, blade part 8 and blade 22 making transverse and longitudinal cuts respectively. Holder 7 is actuated separately to make a second transverse cut. An hydraulic hold down (4), Fig. 2 (not shown), is provided and the bolt 10 may be replaced by means locking the cylinders 13, 14 together. In an alternative embodiment, Figs. 3 and 4 (not shown), the tables 17 and 18 rigidly fixed to holders 6 and 7 are replaced by tables (27a), (27b), pivoted to the shear frame, which are swung, by hydraulic cylinders (30), out of the paths of blades 8 and 9 for full width cutting, at least the table (27b) carrying the blade 24 remaining in operative position for simultaneous half width and longitudinally cutting. The upper transverse blade may be divided into two unequal parts.

[Class 8 (i).] The fan 16, Fig. 1, draws air into an impermeable dust-collector 23 through a filter 25 and into a conduit 26; the fan also draws air through apertures 22 in the motor housing. The air is discharged through a pipe 19 to atmosphere either through openings 20 in the casing or through a connection 13 for a last hose. In a modification, the conduit 26 is enlarged to receive the motor which is cooled by the air coming from the filter. The collector is removable from the casing for emptying. Fig. 2 shows a modification in which the hose need not be detached during the emptying of the dust collector, the hose socket being formed in the lower casing and connected to a curved member 34 forming a union between the casing and the collector. The apparatus may be mounted on a sledge as shown or on wheels.

Green sand cores are moulded and set within the drag of a mould. The lower part of a multiple core-box has four sections 1, 2, (3), (4), each producing a core and all mounted on a frame 5, sections 1, 2 differing from sections (3), (4). The lower core-box part is rammed full of green sand and an overfill added on top of the rammed sand. The multiple core-box upper part 36, mounted on a carriage 31, is brought above the lower part and rammed down by a cylinder 44 to impress the upper core contours on the green sand overfill. After ramming, the carriage 31 is returned to its original position, the four sections 1, 2, 3, 4 of the lower core-box part are separated and the bottom portions 68, (69), 74, (75) of these sections removed by cylinders 80, (82), 83, (85). The core-box parts 1, 2 and 3, 4 are rotated through 90 degrees about horizontal axes 10, 11 respectively to abut (1 with 3 and 2 with 4) and to form two complete two-component cores, one of which is shown in Fig. 5. A second carriage 32 moves to a position above the cores. and engages the core-box sides 65, (67), 71, (73) which are removed by a cylinder 94. The carriage. 32 returns to its original position, the drag 109 of a twin-cavitied casting mould is lowered over both two-component cores and clamped on to cover-plate 26 of the frame 5. The drag and eores are rotated through 180 degrees about a horizontal axis 12 (Fig. 8). A roller frame 129 is raised to meet the drag 109, which is unclamped from the cover-plate 26 and lowered with the roller frame into an inclined position on supports 134 and 135. The drag then rolls out of the apparatus via a second roller frame 133, actuating during its,movement a limit switch (not shown) which resets the apparatus for another core-production/coresetting cycle. The machine is hydraulically or pneumatically powered and the operation sequence may be programme controlled. Moulds and cores.-A mould for casting two gear-box cases for motor vehicles comprises a drag 109 and a cope 109b (Fig. 7d) with two cavities, each containing a two-component (I, II) core of which at least one component is of green sand. The components may be located by core-prints (not shown) and if desired, glued together. One component can be of resinbonded sand.

The walking beam 25 of a furnace is driven with a rectilinear motion approximating to Simple Harmonic Motion by a constant velocity double acting pivoted hydraulic ram 6 through a toggle 11, 13 connected to the common pivot 15 of a second toggle 16, 17, a bell crank 19, 21, mounted on a fixed pivot 4, and a connecting rod 23. Toggle links 11 and 16 have fixed pivots 2 and 3. The piston 8 of ram 6 is decelerated at the end of its stroke by an adjacent plug 44 or 43 engaging a cushioning chamber 36 or 35 to block off the free exhaust and piston operating line 34 or 33 and feed the hydraulic fluid through a throttling needle valve 40 or 39. A one-way valve 42 or 41 allows line pressure 34 or 33 to act on the whole piston area at the beginning of each stroke. A solenoid-operated two-way and exhaust valve 30 reverses the piston direction by alternately supplying lines 33 or 34. The hydraulic fluid is fed to valve 30, through one-way valve 29, by pump 26 whose output is controlled by a solenoid valve 45-47 tripped by limit switches on the piston rod 7 to exhaust at the end of each piston stroke until the valve 30 has reversed.

Abstract: 259,157. VogtlandischeMaschinen Fabrik (vorm. J. C. & H. Dietrich), Akt.-Ges., and Wohlrabe, O. June 21, 1926. Rotary offset machines.-A rotary multi-colour offset printing-machine is constructed to prevent premature wear of the printing-plates due to concussions occurring in the offset cylinders. To this end, the offset cylinders 6, 7, 8, 9 which receive their impressions from plate cylinders 10 are arranged symmetrically relatively to the impressions surfaces a, b, c, d on the impression cylinder A, and the arrangement is such that the offset surfaces all commence printing at the same instant so as to balance the forces tending to vibrate the offset surfaces. Also the plate and offset surfaces occupy circumferentially less than 180‹ of their respective cylinders, and these are arranged so that the offset surfaces are never in contact with !both the impression surface and the printing-plate at the same time. To attain this, the cylinders are set so that the angle between the lines joining the centre of the offset cylinders to the centres of the impression cylinder and plate cylinder is at least equal to the angle subtended by the offset surfaces at the centres of their cylinders. The sheets are fed from a table 1 and delivered by cylinders 4. The leading edges of the surfaces a - - d are spaced apart a distance equal to the perimeter of the offset cylinders.
