Title: Improvements in apparatus for indicating consumption of liquid fuel or the like
IPC: G01F9/00
Filed: 1930-08-25
Abstract: 368,223. Apparatus for measuring the distance rate of consumption of powerproducing substance by a vehicle. PROPHETTE, J. V., 22, Rue Michelet, Montdidier, Somme, France. Aug. 25, 1930, No. 25317. Convention date, Aug. 28, 1929. Void [Published under Sect. 91 of the Acts]. [Class 106 (iii).] The Specification comprises apparatus for measuring the distance rate of consumption of a powerproducing substance, e.g. liquid fuel, electric current, &c., by a vehicle, vessel, aeroplane, &c. The time factor involved in the measurement may be infinitesimal or may have a small but finite value or may correspond to the time for absorbing a given quantity of fluid or to the time corresponding to a definite distance of travel. In Fig. 1, a speedometer drives pointer 1 and the time rate of consumption of fluid meter shown or a wattmeter drives the pointer 3. The piston 11 may be replaced by a flexible diaphragm. Indication of the distance rate of consumption takes place at the intersection of the pointers 1, 3 on the set of curves 15. In Fig. 2 the time rate of consumption meter and the speed indicator drive cams 16, 17 respectively, which logarithmically raise two rods 18, 19, a mark 20 on the rod 19 reading on a logarithmic scale on the rod 18 the distance rate of consumption of fluid. In the construction shown in Fig. 3 a rod 24 movable about a stationary axle 25 is controlled by the rod 19 or the cam 17, Fig. 2, and a rod 26 pivotally mounted on the axle 27 slidable along a stationary rod 28 is controlled by the rod 18 or cam 16, Fig. 2. Direct reading takes place by the pointer 37 on the dial 40. In the construction shown in Fig. 4 the pointer 49 is actuated through the milled wheel 45 mounted on the shaft 46 rotated according to the travel of the vehicle and engaging with the disc 44 driven from the fuel or electricity meter 41, a suitable construction of which is shown in Fig. 5. In the construction shown in Fig. 6 the pointer 99 is rotated to give an indication of the distance travelled by the vehicle whilst a definite quantity of fuel is supplied to the motor through the pipe 69 from the chamber 62 and float 61 supplied from the fuel tank through the pipe 68, the pointer being actuated through the wheel 85 and being controlled through the electromagnet 89 periodically energized from the motion of the vehicle and the piston device 107 operated from the apparatus 62. The wheel 85 may be actuated from the vehicle by mechanical means instead of through the electromagnet 89. Modified constructions of chamber and float and of electromagnetic and other methods of fuel feeding are described. The apparatus shown in Figs. 2 and 3 can be used to indicate average distance rate of fuel consumption by actuating the cam 16 by reducing gearing according to the fuel consumption, and the cam 17 by reducing gearing according to distance travelled.

Abstract: 1393132 Transferring crown seals KOMBINAT NAGEMA VEB 31 May 1972 25498/72 Heading B8S Crown seals are transferred from feed channel 1 by a guide disc which has a continuously decreasing radius between peripheral notches so that the crown seal starts to move towards the arcuate portion of a notch almost immediately after the preceding crown seal has arrived in the arcuate portion of the preceding notch. Duplication of crown seals in arcuate portion is avoided by an electrically, pneumatically or hydraulically operated shut off device preventing the foremost crown seal in the feed channel from moving forward and along the edge of the guide disc if a crown seal is already present in the approaching notch. Blowers 4 assist forward movement of the crown seals into contact with the guide disc.

Filed: 1948-10-01
Abstract: 654,011. Undercarriages for aircraft. GEISSE, J. H. Oct. 1, 1948, No. 25615. [Class 4] [Also in Group XXXII] An aircraft undercarriage fitted with a castorable landing wheel comprises a torsion spring element for damping shimmy oscillations. As shown in Fig. 1, the undercarriage leg incorporates an oleo-pneumatic shockabsorber in which the dashpot piston 6 is carried by a laminated piston rod 5 of rectangular cross-section and passing through the plate 3 separating the upper and lower chambers 10, 11 of the shock-absorber. Shimmy of the landing wheel is resisted by torsion of that portion of the rod 6 below the plate 3, the length of which decreases with increase of load, thus increasing the torsional resistance. Liquid-transfer ports a are provided in the plate 3, and the area of these may be varied in accordance with the load on the undercarriage by tapering the sides of the rod 5. Fig. 6 shows an arrangement in which the torque links 17, 18 connecting the relatively movable portions 14, 16 of the undercarriage leg are laminated, and act mainly in torsion to reduce shimmy when the undercarriage leg is fully extended, but increasingly in bending as the leg shortens under load. In the third embodiment shown in Fig. 9, the relatively movable portions of the undercarriage leg 30, 32 are interconnected by a U-shaped leafspring 31.

Title: Improvements in or relating to radio frequency dielectric heating apparatus

IPC: H05B6/76
Filed: 1958-08-11
Abstract: 882,441. Dielectric heating. RADYNE Ltd. Nov. 11, 1959 [Aug. 11, 1958; Feb. 13, 1959], Nos. 25731/58 and 5120/59. Class 39(3) [Also in Group XL(b)] A radiation attenuation duct for radio frequency dielectric heating equipment having a fundamental frequency less than 500 mc/s. includes spaced transverse conductive partitions shaped and arranged to provide a path for passage of material to be heated. The duct 24, Fig. 2, is connected to the wall of a heating compartment 18, the edges of upper and lower partitions 26, 28 being spaced to provide a passage for a conveyer band extending into the compartment. The end member 34, Fig. 4, is provided with a central slot of restricted length. The upper and lower partitions 26, 28 may be staggered in the axial direction of the duct (Fig. 5, not shown). The effect of the partitions is to raise the cut-off frequency of the duct and thus provide attenuation of harmonics below the new cut-off frequency. Further attenuation may be provided by non-inductive resistors 36, 38, Fig. 10, connected between upper and lower partitions and by resistive panels 46 attached to the edges of the partitions 26, 28. These may extend the full width of the duct (Fig. 9, not shown). They may be made of graphite-surfaced resin-bonded paper board or asbestos board. Other materials such as wood, foam rubber, foam polystyrene, textile material or cement mixed with graphite are also stated to be suitable. The resistance of the boards may be arranged to diminish towards the sides of the duct. In the construction of Fig. 8, use is made of transverse resistive boards 42 bolted to the partitions 26, 28 at points 44. In a modification, the partitions have the same form as the end member 34, Fig. 4, whereby a central passage is provided in the duct.. This may be completely enclosed by resistive boards forming an inner duct. Additional attenuation of particular frequencies may be obtained by adding to the end of the duct quarterwavelength extensions having the same section as the aperture in the end member 34. Quarter-wave sections may also be inserted between the duct and the heating compartment or between two or more ducts arranged in series. The conveyer may be made of insulating material. If it is made of metal it is necessary to provide a conductive or capacitative coupling between the conveyer and the duct. Specification 882,442 is referred to.

The width of the gap 17 may vary between the width of the spoiler and three times this width. The spoiler may be retractable into the aerodynamic surface. Channels may be provided and extend from the zone forward of the spoiler to a zone rearward to prevent pressure build-up forward. Fig. 4 shows spoilers 26, 27 retractively mounted in the nose 30 of a missile and arranged adjacent surfaces 31.

In one method of assembling the parts as shown in Fig. 1, the original is severed adjacent to the line following an incorrect line or groups of lines. The strip b bearing the corrected portion is severed from its sheet above the top line and placed over the incorrect lines of the part a of the original. The next correct part c of the original is then placed over the blank part of the strip b. In another method of assembling the parts as shown in Fig. 3, the faulty lines are removed from the original and the correct portions a<1>, c<1> placed above blank spaces in the strips b<1> beaming the corrected lines. To facilitate cutting the sheet between the lines, guide marks may be provided on the margins. Column lines and the frame lines of advertisements may be inserted after the parts of the corrected sheet have been assembled.
