Filed: 1925-02-06
Abstract: 251,368. Bach, W. B., (trading as Bach & Co.), and Howard, W. F. Feb. 6. 1925. Windscreens.-For securing a windscreen in an adjusted position a fixed tubular socket houses a clamping bolt which passes through a tubular pin and has a screw-threaded connection with a clutch member, the bevelled face of which coacts with the bevelled end of the tubular pin on which the windscreen is mounted. As shown, the tubular pin 12 through which the clamping bolt 15 passes to engage the nut 12b, serves as a support for the screen 5 positioned behind the front seat 14 of the vehicle. When the bolt is tightened, the bevelled faces slide over one another and effect a transverse displacement of the parts 12, 12<b> so that they bind against the lining of the member 13. The bolt is loosened to adjust the screen, when the part 12 is free to be moved in the tubular socket until the screen is in the desired position.

Filed: 1956-02-02
Abstract: 788,379. Ventilating apparatus. LARSSON. G. E., PERSSON, S. 1., and AHLSTROM, S. A. Feb. 2, 1956 [Feb. 3, 1955; Sept. 27, 1955], No. 3372/56. Class 137 A ventilating and space heating apparatus comprises a lower fresh air compartment 1 and an upper compartment which is partitioned into a heat chamber 5 accommodating a convector 4, and a bypass chamber 6, the ventilation air being ejected into the upper compartment through holes 2a in a roller 2 which is rotatably mounted in the upper wall of the compartment 1 so that the ventilation air can be directed in the desired proportion towards the two chambers 5 and 6, or wholly towards one, or the other, chamber. Due to the ejector action, room air, sucked into the apparatus through an opening 3, mixes with the rising ventilation air and'passes out through openings in the top of the apparatus. When all of the ventilation air is directed toward the by-pass chamber 6, the tendency for some air to rise upwards through the convector 4 is counterbalanced by a subpressure which is produced by room air as it is sucked in through the opening 3, and tends to suck air downwards through the convector. For controlling the supply of fresh air the roller is provided with two sets of holes, one set of holes 8 being larger than the other set 7, and one set being presented to communicate between the upper and lower compartments while the .other is shut off by means of screens 9. In a modification the roller 2 is replaced by a nozzle having adjustable directional vanes.

Title: A process of and means for the manufacturing of carbides and other oxidisable substances
IPC: C01B32/942
Filed: 1937-02-09
Abstract: 488,296. Rotary furnaces for carbides &c. ZOTOS, G. Feb. 9, 1937, No. 3841.. Convention date, Feb. 12, 1936. [Classes 51 (i) and 51 (ii)] In the manufacture of carbides and other oxidizable materials in a furnace which is rotated at such a speed that the charge distributes itself uniformly over the inner periphery, an axial combustion zone is established in the furnace and between this zone and the charge a non-oxidizing atmosphere is maintained. In the apparatus shown, air or oxygen is injected through the axial nozzle 9, and around this carbon monoxide, in excess of that necessary for combustion, is supplied through the conduit 7. The products of combustion are regenerated in the coal or coke-filled stove 10, and are returned through the conduit 8, circulation being assisted by gas jets 12, 13. Surplus gases are taken off through 15 and used for the production of oxygen. The process may be continuous or intermittent, and in the latter case two furnaces are employed, one of which is being charged and preheated while the other is in active operation. Coal dust may be used as fuel instead of or in addition to carbon monoxide, and during the later stages of the process carbon may be supplied to form a protective layer on the charge.

Filed: 1975-01-29
Abstract: 1492833 Protecting retro-active systems SIEMENS AG 29 Jan 1975 [31 Jan 1974] 3982/75 Heading G3N To monitor and protect a numerically controlled machine tool, wherein a desired movement of a machine part is represented by an incremental pulse train, a displacement controller 2 providing a difference #s between the desired movement pulse train on line 5, and a corresponding actual movement pulse train on line 6, the difference controlling a drive of the machine part, the frequencies of the pulse trains on lines 5 and 6 are compared in unit 21, and should the frequency difference exceed a predetermined limit, pulse generator 20 is activated to provide additional { high frequency } pulses in the sense of the actual movement pulses to the controller 2 to slow down the drive, such slow down taking place should movement take place without the production of actual movement pulses. An error or warning signal may be emitted when the generator 20 is activated. The desired, and actual movement pulse trains are accompanied by corresponding sign signals, of normally opposed polarities in steady operation, on lines 7 and 8, the sign sense of the error signal #s being the same as the desired sign signal on line 7. During steady operation sign comparator 24 monitors the above three signs, and a fault signal St is generated unless the desired and error signals have the same sign sense, opposed to that of the actual movement signal. A register 23 counts a pulse train from generator 22, and is enabled by the error signal #s, and reset by the desired movement pulses. Should the error signal persist in the absence of desired movement pulses, the register 23 can count to its capacity, a fault signal St being then delivered. Servo system details:-The pulse train from displacement controller 2 is converted into analogue form (d/a converter not shown) and passed to analogue controller 3 also receiving an actual speed signal from tachogenerator 9, the controller providing signals for low inertia D.C. motor 4. Movements of spindle 10 coupled to the machine carriage 11 are communicated to the rotor of resolver 13, the filtered, demodulated resolver output, a D.C. voltage; whose amplitude represents the momentary deviation of the rotor with respect to a supply reference phase; passing to voltage-to-frequency converter 18 whose output constitutes the actual movement pulse train. The latter is additionally fed to a generator 14 of quadrature A.C. waveforms supplied to the resolver, to reset the phase reference of the latter to accord with the new rotor position. The frequency of the pulse train on line 5 represents the desired speed of carriage movement, the pulses being provided by an interpolator 1. Generator 19, provides a low frequency pulse train, to reduce the required sensitivity of the voltage-to-frequency converter 19.
