Title: Improvements in tunnel kilns and the like
IPC: F27B9/20
Filed: 1933-05-18
Abstract: 419,535. Tunnel kilns. SHOOK, T. W., Kingsway Chambers, Kingsway, Stoke-on- Trent. May 18, 1933, No. 14379. [Class 51 (ii).] In a tunnel kiln having, in the firing zone 18, burners 19 delivering directly into the ware passage, and muffle heating-chambers 17 along each side of the preheating zone 14, there are provided dampers 20 by which the hot gases from the firing zone may be caused to pass to the stack through the ware passage 14, the chambers 17, or simultaneously through both in any desired proportions. Additional heat may be supplied to the preheating zone by auxiliary burners 19<a>, 19<b>, the former delivering into the muffle chambers 17 and the latter directly, through ports 26, into the lower part of the tunnel. A portion of the gases from the burners 19<b> may be directed, by opening dampers 28, Fig. 5, to ports 29 in the roof 13 of the tunnel. The vapours evolved in the preheating zone 14 are withdrawn through ports 22 and pass, by way of flues 23 controlled by dampers 24, into the muffle chambers 17; removable brickwork 25 is provided at the outer ends of the ports 22 to facilitate cleaning or inspection and to permit, if desired, escape of the vapours direct to the atmosphere. The ports 26 may be used in the same manner as the ports 22, in which case the burner openings are closed up and dampers 27 opened.

Title: Improvements in and relating to recording apparatus
IPC: G01F5/00
Filed: 1948-05-27
Abstract: 661,102. Supply meters. SMITH METERS, Ltd., and CHARLES, J. A. May 27, 1949, No. 14387/48. Class 37. [Also in Group XIX] Apparatus of the periodic counter type associated with an electricity meter for providing a graphical record of consumption rate, has an independent constant speed mechanism for both advancing the record surface and periodically interrupting the meter drive to the marking stylus adjustment elements. A meter driven spindle 13 has its lower bearing in a spring-actuated lever 27 pivoted at 28, and carries a pinion 26 normally meshing with a wheel 18 which it drives (counterclockwise, Fig. 4) from an initial position determined by the engagement of a pin 21 on the wheel with a stop 22. A crankarm 51, constantly rotated by a clockwork 35, periodically (at five minute intervals) engages the tail of lever 27 to disengage the pinion momentarily, the wheel 18 then returning to its initial position under the action of a spring 20. The successive displacements of the wheel 18 are a measure of the consumption rate and are registered by a ratchet wheel 23; this wheel is carried forward by the wheel 18 through contacting pins 24, 25 and then held, during the ensuing period, by a pawl 31. At the end of each period the crank-arm 51, immediately prior to tripping the pinion lever 27, disengages the pawl 31 so that the ratchet wheel 23 is moved back by a return spring to the position in which the pins 24, 25 abut when there has been a drop in consumption. The ratchet wheel 23 is connected through a pinion 30 and a gear sector 33 with the pivot spindle 34 of a recording stylus 76 which marks a record sheet passing over a drum 54 also driven by the clockwork 35. A continuous record of consumption rate, averaged over short periods, is thus marked on the record sheet.

Title: Braking buffer stop
IPC: B61K7/18
Filed: 1959-04-30
Abstract: 897,702. Buffers. STABEG APPARATEBAUGESELLSCHAFT. April 30, 1959 [May 2, 1958], No. 14702/59. Class 104 (2). In a buffer stop slidably carried by the frictional engagement of wedge members on surfaces provided on fixed flanged rails extending parallel to the direction of impact in which the braking of the stop is effected by progressively increasing the wedging action on the rails in the direction of displacement on impact, the lines of intersection of a vertical plane parallel to the centre lines of the rail track and the plane of the track with the top surfaces of the rails which serve as friction rails, and with. the plane of the inclined under-surfaces of top flanges of the rails, diverge in the direction of impact in the case of at least one flanged rail on each side of the track. In the arrangement shown in Fig. 3 a buffer stop having a triangular structure, Fig. 1 (not shown), is secured to inverted rail sections 5, the inclined upper surfaces 7 of which engage the inclined under-surfaces 6 of the rail heads of a track rail 1 and a brake rail 2. The rails 5, 1 and 2 are engaged by wedges 10 between the top surfaces 9 of the track and brake rails 1 and 2 and the inclined under-surfaces 8 of the rails 5. The thickness a of the upper flange of the track and brake rails 1 and 2 increases in the direction of displacement of the buffer on impact. Consequently as the buffer is displaced the surface pressure between the various sliding surfaces increases. In a modification, Fig. 4 (not shown), the brake rail 2 converges in the direction of impact towards the track rail 1, thus resulting in an increase in the surface pressure between the sliding surfaces as the buffer is moved in the direction of impact. In a further modification, Fig. 5 (not shown), the rails 5 are arranged to engage beneath the undersurface of the upper flanges of the track and brake rails 1, 2 on the outer sides of such rails and the brake rail 2 diverges in the direction of impact away from the track rail 1.

Title: Distortion reduction on modulated amplifiers
IPC: H03F1/08
Filed: 1943-09-10
Abstract: 566,844. Valve modulating circuits. STANDARD TELEPHONES & CABLES, Ltd. Sept. 10, 1943, No. 14867. Convention date, Nov. 16, 1942. [Class 40 (v)] In order to avoid distortion in an anodemodulated carrier amplifier, an impedanceinverting line or network is interposed between the carrier source and the input of the amplifier. As shown, the carrier is fed to a push-pull preamplifier D, which feeds the modulated amplifier A through a quarter-wave line N. The tuned output circuit 11 of stage D and the tuned input circuit 15 of stage D are arranged to match the impedance of the respective valves with that of the line N. The anode supply circuit of the stage A includes a transformer secondary coil 29, the primary of which is in the output circuit of a signal amplifier B. The modulating stage A operates as a Class C amplifier, and the maximum signal voltage in coil 29 is made equal to the H.T. supply voltage. As the anode voltage of stage A varies, the input impedance of this stage also varies and this normally gives rise to distortion. A rise of input impedance of stage A is, however, owing to the action of the impedance inverter N, accompanied by an increased carrier output from the stage D, and distortion is thus corrected or reduced. The quarter-wave line may be replaced by an equivalent network, and the impedance-matching networks 11, 15 may be replaced by transformers, Figs. 2 and 3 (not shown).

Filed: 1972-03-30
Abstract: 1376759 Rolling mills FRIEDRICH KOCKS 30 March 1972 [2 April 1971] 14967/72 Heading B3M A stand-changing assembly for a multi-stand rolling mill enables individual stands 2, or groups of stands, to be removed from the rolling line by the use of cantilever arms 18 which extend above the stands. In one form, Fig. 1, each stand is supported by a lower support 26 and upper bearing surfaces 28, the surfaces being disposed in a carriage 22 which can be moved along the cantilever arm. To remove the stand from the rolling line, the stand is shifted to the left (dotted lines), to disconnect it from driving spindles 14. The carriage 22 then lifts the stand, moves it to the left, and deposits it on a trolley 20. The arm 18 can be pivoted to the dotted position when not in use. In an alternative arrangement, Fig. 4, the lower support 26 is dispensed with and the stand is urged towards the right by a cylinder 58 into engagement with supports 34 and 36. The stand can then simply be moved to the left by the carriage 22, once the cylinder has released its clamping arm 56. The carriage 22 can be arranged to move laterally together with the cantilever arm 18, if desired (Fig. 3, not shown). The carriage 22, Fig. 4, houses a pair of pneumatically or hydraulically operated hooks 46 which engage pins on the stand. The stand is thus urged upwardly against support surfaces 28. The assembly of the hooks and stand can be raised or lowered by a cylinder 42.
