Title: Improvements in or relating to exhaust silencers of internal-combustion engines
IPC: F01N13/00
Filed: 1945-06-15
Abstract: 604,452. Exhaust-silencers. TRIGGS, W. W. (Maxim Silencer Co.). June 15, 1945, No. 15303. [Class 7 (ii)] In an exhaust-silencer of the type in which water is added to the exhaust gases to quench sparks, the water is separated from the gases before discharge to the atmosphere. Water is sprayed from the inlet 19 (Fig. 1) into the hot exhaust gases entering through conduit 16 and the gas and entrained water are projected against a perforated screen 20 adjacent the end 11 of the inlet chamber 14 to effect almost complete separation, the water being removed by the drain 22 and the gases flowing by tubes 23 through the partition 13, on to screen 24 in the outlet chamber 15 where any remaining water is separated, the gases then being ejected through two outlets 27. The tubes 23, 27, fitted with anti-resonant apertures and slots are located near the pipe 16 so that the exhaust gases can be re-heated by the portion of the pipe 16 in chamber 15 before leaving. A further screen 21 may be provided above the bottom of chamber 14 to avoid splashing, suitable dimensions for the holes in the screens and the distance of the end of pipe 16 from screen 20 being given. Inlet tube 16 and outlet tubes 27 may be provided with fins on the exterior to assist in the transfer of heat, or the outgoing gases may be re-heated as shown in Fig. 11 by diverting a portion of the entering, hot exhaust gases into the outlet chamber 52 through a small, subsidiary spark-arrester silencer 51, or through a valve 57 (Fig. 12) and subsidiary silencer 54 to mix with the outgoing gases in the outlet pipe 56, which may be elliptically shaped. Alternatively, an electric heating element may be situated in the outlet pipe. In a modified silencer (Fig. 8) the inlet pipe 35 with water inlet 36 is bent downwards to direct the gas and water against a screen 40, the gas being delivered on to a second screen 41 in the outlet chamber 34 through pipes 38 and escaping through a slotted pipe 44. In a further modification (Fig. 15), the inlet pipe 62 is contained inside a larger pipe 64 to facilitate re-heating of the gases which are conducted from the inlet to the outlet chambers through the hemisperical space between the pipes, which may contain perforated fins 66. To avoid irregular discharging of the water through the drains, a deep tank 69 (Fig. 17) with a secondary drain 70 is provided round the drain-pipe 68, the head of water formed thereby being greater than the gas pressure. Other forms described comprise a short snout 73 (Fig. 18) discharging opposite the main drain-pipe 77 into a wide enclosure 74 with vent holes 75 for air, or a drain-pipe fitted with vanes to swirl the water and entrap small amounts of exhaust gas. Specification 604,503 is referred to.

Title: Improvements in or relating to fatigue testing machines
IPC: G01N3/06
Filed: 1945-06-21
Abstract: 616,968. Automatic control. AMSLER & CO., A. J. June 21, 1945, No. 15815. Convention date, March 7. [Class 38 (iv)] [Also in Groups XIX and XL (b)] In an automatic amplitude regulator for fatigue testing machines in which the loadapplying means is alternately actuated and relieved by means including electron tubes, the optically magnified peak values of the amplitudes of vibration of the load applied are adapted to influence the actuating means through a photo-electric member so that the amplitude values are maintained constant. As shown, for compression and tension tests, a specimen or a measuring member C is arranged between vibrating masses M1, M2 to vibrate at its natural frequency and to be deformed according to the relative displacements of these masses. The vibration is transmitted by means of a pick-up (not shown) to an electron tube amplifier 11 which feeds a magnet 17 to keep the system vibrating in synchronism. The relative displacement of the masses actuates a plane or concave mirror 2 through steel bands 1 to reflect a beam of light 3 from a lamp 4 and lens 5. The reflected beam 6 moves over a scale 7 and a shield 8 slotted at 18. When the amplitude of movement of the beam 6 is such that the latter passes through the slot 18, it impinges on a photo-electric cell 9 which delivers impulses in opposite phase to those of the pick-up to decrease the amplifying ratio of the amplifier 11 and thus control the vibration of the masses M1, M2. The shield 18 and cell 9 can be vertically adjusted. In a modification, a specimen and a measuring member are arranged in alignment between the masses, and either the alterations in the length of the member of the specimen actuate the mirror 2; in the latter case the arrangement serves to measure the load applied to the specimen. The invention can be applied to fatigue-testing machines for shearing, torsional and bending tests.

Abstract: 683,390. Gripper shuttle looms. MASCARENHAS, E. G. June 15, 1949 [April 29, 1949], No. 16004/49. Classes 142(ii) and 142(iii) A double-ended gripper shuttle is picked by solenoids surrounding the shuttle boxes under the control of a switch actuated by the shedding mechanism and a shuttleoperated switch on each shuttle box; selection of different wefts is controlled by a pattern mechanism and the weft is cut after each pick by solenoid-actuated shears controlled by shuttle-operated switches on the boxes. Gripper shuttle. The shuttle is of rectangular cross-section, having a magnetized middle portion and tubular ends 42, Fig. 14, housing spring jaws 46 for gripping the weft 63. When the shuttle arrives in a box, a loose rod 44 encounters a weft feeder 60, 61, Fig. 20, which stops the rod so that, as the shuttle continues to move, the rod opens the jaws at the opposite end, Fig. 14, to release the weft 63; the weft feeder, Fig. 20, meanwhile enters the jaws 46a so that when the shuttle is picked, it grips the weft 63a. Picking mechanism. On arrival at box 31, Fig. 6, the shuttle 42 strikes a pip 39 on a blade 38 to close a switch 41; the switch is in series with a change-over switch actuated by the shedding mechanism (which puts the two picking motions into circuit alternately), so that when both switches are closed, a solenoid 32 is energized to propel the shuttle. Checking shuttle. On arrival in a shuttle box 31, Fig. 10, the nose of the shuttle 42 passes through the box and meets a plate 48 mounted on a platform 50 loaded by a spring 54 consisting of a zig-zag strip of leather; when the shuttle has been brought to rest, a spring 57 returns the plate 48 to its normal position. Cutting weft. As the shuttle 42 enters a box 31, Fig. 5, it lifts a feeler 36 to close a switch 37, thereby energizing a solenoid 67, Fig. 10, at the opposite end of the loom to actuate shears 72. Weft pattern mechanism. A ratchet wheel (not shown), advanced one tooth on every pick, carries pins which actuate switches whereby solenoids 65, 65a, Fig. 10, are selectively energized to slide one or other of two weft feeders 60, 61 into line with the shuttle.
