Title: Chequer bricks for the chequer work of regeneratively operated hot-blast stoves
IPC: F28D17/02
Filed: 1962-03-19
Abstract: 994,833. Thermal regenerators. STEULER INDUSTRIEWERKE G.m.b.H. March 19, 1962 [March 23, 1961], No. 10371/62. Heading F4K. Chequer brick work for a hot blast stove comprises a plurality of flow zones each joined by a mixing zone, the bricks forming the flow zones being identical and having passages therethrough which are aligned to form gas flow paths and the bricks forming the mixing zones being identical and having larger passages therethrough, the dimensions of the larger passages being such that each larger passage can be aligned with a plurality of gas flow paths and the bricks of the mixing zone being so arranged that the gas flow paths in a flow zone communicating with one passage in an adjacent mixing zone communicate with a plurality of passages in the other adjacent flow zone. The bricks A of the flow zones are as shown in Fig. 1 and have pairs of channels 4, 4a of equilateral triangular cross-section arranged around the vertical axis X-X of the brick, the channels being defined by radial walls 1 and separating walls 2. A circular recess 5 is formed at the centre of the brick and part circular recesses 5a are formed at the outermost points of intersection of the walls 2. Corresponding projections (not shown) are formed on the underside of the brick to enable the bricks to be stacked together to form a flow zone. The bricks B forming the mixing zone are as shown in Fig. 2 and are the same as bricks A except in that the portions of the walls 2 separating the channels 4 and 4a are omitted to define channels 7 of rhomboidal cross-section, and the recesses 5 and 5a are omitted and replaced by recesses 8 located as shown. The projections on the underside of the brick are the same as those of brick A. On assembly a horizontal layer of bricks B is placed on a flow zone formed by superimposed horizontal layers of bricks A so that each pair of passages 4, 4a communicate with a separate, single, passage 7. Further bricks A are then placed on top of the first layer of bricks B and, due to the location of the recesses 8, these bricks are offset with respect to the bricks A beneath the layer of bricks B. If now a second layer of bricks B is placed on the further bricks A the passages 7 in this second layer will be offset with respect to those of the first layer. Thus, the two passages 4 and/or 4a of the further bricks A which communicate with a single passage 7 in the first layer of bricks B will communicate with two different passages 7 in the second layer of bricks B.

Title: Process for the drying of oximes
Inventor: MEIER GERHARD
Filed: 1956-04-05
Abstract: Oximes are dried by blowing a gas through melted oximes at an increased temperature, crude melted oximes are placed in a heated pipe or tower and heated gases, e.g. nitrogen and air in finely divided or distributed form are conveyed over the oxime.  When the temperature is increased the gases become charged with vapours of the water and ketone contained in the oxime and the oxime may be allowed to stay in the pipe until it is practically free from water and ketone.  The escaping gas and vapours are then cooled together with any oxime blown out during the distillation by the hydroxylamine sulphate solution which is used in the production of the oximes.  The ketone contained in the vapours is thus converted immediately to oxime.  After cooling the gases and vapours the hydroxylamine sulphate is conveyed to the oximation apparatus.  In examples, o-methylcyclohexanone oxime is dried and purified by passing nitrogen, equivalent to 100 times the volume of the oxime, through a heated tower for 3 hours and cyclohexanone oxime purified in a similar manner, using air preheated 110-120 DEG  C. instead of nitrogen.

Title: Book or Pamphlet Covering Machine.
IPC: B42C11/04
Filed: 1916-07-26
Abstract: 108,880. Marks, E. C. R., (American Assembling Machine Co.). July 26, 1916. Bookbinding-machines.-An endless conveyer travelling continuously carries the book in automatically-operated clamps, back-downwards, over a glueing-roller, a cover-applying device, a pressing and cover-breaking device, and, finally, to a discharge shoot and stacking-apparatus. The books are fed into the machine by a conveyer 6 to the clamps 1, which are closed by springs 16 as soon as the cam-surface 170 allows the springs to act. The covers are fed from the opposite end of the machine by a conveyer 39, from which they are taken by tapes 46 and carried round the coverapplying drum 8. Glue is applied to the back of each book by the roller 7, which is raised at the right moment for the purpose. Should there be no cover coming on to the drum 8 in proper position for the book, a detector device trips the mechanism by which the roller 7 is raised, and the book passes on unglued. Beyond the drum 8 are situated the devices by which the cover is pressed firmly against the back of the book and " broken " by jaws which nip the book close to the back. These devices are raised into position at the proper moment and while in action are moved forward at the same speed as the conveyer; after completing the operation, they are lowered and return to the starting point. The book, with the cover attached, passes round the machine to the delivery shoot 10, before reaching which it is released from the clamp by the action of the camsurface 170 on the roller 17. After passing down the inclined shoot 10, the books are arranged by a stacker in a transverse trough 111. To prevent the books from shifting in the clamps when pressure is applied to them, cam-surfaces 171, 172 are placed above the glue roller 7 and the coverpressing mechanism 9, these cams assisting the springs 16 to maintain the clamps closed.

Filed: 1969-02-28
Abstract: 1,247,489. Cutting &c. MASCHINENFABRIK TURNER A.G. 28 Feb., 1969 [11 Sept., 1968], No. 10689/69. Heading B4B. [Also in Division C6] Hides are fed to a hide splitting or other leather working machine by a pair of gripping rollers, one of which is divided into a plurality of rings 11 which, as shown diagrammatically by blocks 5 in Fig. 4, are individually urged towards the other roller 3 by separate pneumatic piston-and-cylinder devices 8 the pneumatic pressure in each of which is controllable, either by separate regulator valves 4 or, as shown, by a combination of some separate regulator valves and one or more regulator valves controlling, via interconnecting pipes 7, a plurality of the devices 8. The machine shown is a band knife hide splitting machine, the knife of which is shown at 12. In order to ensure correct splitting action there is provided, in each of the devices 8, a piston 20 slidable within a ballbearing sleeve 23 in a cylinder formed in a block 22, the piston being acted on by a rolling type diaphragm 27 sealed to the block and providing thereby a sealed pressure chamber within a cap 26 to which compressed air is supplied by the regulating valve 4, via a surge-limiting chamber 25. A rotary cam 24 determines the maximum lift of the piston, and hence the maximum height of the respective ring 11, which is rotatable within constraining members 14-17 which are carried by a support at the upper end of the piston, the upper constraining members 16, 17 being adjustable. All of the rings 11 are driven from a common driving shaft 10 through the interengagement of gear teeth provided internally on the rings and externally on the shaft.

Title: Improvements in wave guide switches
IPC: H01P1/12
Filed: 1946-04-09
Abstract: 608,839. Electric resonators. WESTERN ELECTRIC CO., Inc. April 9, 1946, No. 10896. Convention date, Dec. 10, 1941. [Class 40 (viii)] [Also in Group XL (c)] A wave-guide switch comprises a hollow metal pipe and a member such as a rod or vane insertable into and withdrawable from the pipe, the member when withdrawn allowing the transmission of wave energy through the pipe, and when in position in the pipe, operating to prevent transmission of wave energy through the pipe. Fig. 2 shows a simple embodiment in which rotation of a spindle 6 causes a rod 5 to enter a slot 7 and cause detuning of a resonant chamber 4 formed in wave-guide 1 between irises 2, 3, thus preventing the transmission of energy through the wave-guide. In Fig. 4, the flow of energy in the main guide 1 is controlled by the tuning and detuning of a chamber 4 arranged in a branch with the interception of a shunt reactance X such as an iris. With appropriate spacings, the arrangement may be made such that energy flow in the main guide is stopped either when cavity 4 is tuned or when it is detuned. The resonant chambers may be placed in the arms of symmetrical Y-junctions to render the branches alternatively conducting, Figs. 6 and 7 (not shown). Fig. 8 shows an arrangement for switching the energy from a main guide 10 alternatively through filter 4 or identical filter 9, made as in Fig. 2. As rod 5 is common to both filters, they are alternately detuned on rotation of the rod 5. In Fig. 9 energy is alternately switched to the side arms A, B of a T-joint by means of side arm resonant chambers as shown in Fig. 4, in which iris 12 acts as the reactance X. Alternate detuning of the chambers is effected by endwise movement of rod 13. Fig. 10 shows two filters having the same tuned frequency coupled end-to-end to give a band-pass effect. The detuning rods 5 are operated in synchronism. Alternatively, the filters may be coupled side-by-side, Fig. 11 (not shown). More than two filters may be used to increase the band width. Fig. 12 shows an arrangement for feeding energy from a main guide to a number of branch guides in succession. The branch guides are in the form of resonant chambers opening into the main guides by irises which are arranged at half-wavelength intervals at an odd number of quarter-wavelengths from the closed end of the main guide. Detuning vanes on a shaft 6 are shaped so that one only of the chambers is tuned at any one time and so energy passes through that chamber from the main guide. Fig. 13 shows a switch which does not employ resonant chambers. A vane 19 is rotated by a shaft 20 to close either branch 17 or branch 18 to prevent energy flow from main guide 16. Leakage is reduced by flanges at points C and D.
