Patent GB-688349-A (GB)
Abstract: 688,349. Centrifugal pumps. THOMPSON PRODUCTS, Inc. Feb. 23, 1951, No. 4424/51. Class 110(i) [Also in Group XXVII] Two pumps are submersed in an aircraft fuel tank with their inlets spaced vertically from one another, so that at least one of the inlets is submersed under all conditions. The driving motor 12 is mounted by means of a bracket 13 on the rear wall of an aircraft fuel tank 10 and is directly coupled to a lower pump 24 and by way of a centrifugal clutch 16 to an upper pump 23. Under normal conditions, only the pump 24 is driven, but if its inlet becomes uncovered, the motor 12 speeds up due to the resultant reduction in load, causing the centrifugal clutch 16 to become operative and transmit drive to the pump 23. The pump outlets are connected to a delivery 41 by way of non-return valves 38, 40 which prevent back-flow through the idle pump. When both pumps are submersed, they can be driven simultaneously to increase the pumping capacity, as during take-off of the aircraft, by speeding up the motor 12 to cause engagement of the clutch 16. In a modification, the entire unit is inserted through an opening in the bottom wall of the tank which is closed by the base plate of the lower pump. Mounting bolts pass through the base plate and are threaded into a mounting ring disposed on the bottom wall of the tank around the opening. The delivery pipe passes downwardly through the base plate.

Abstract: 726,037. Turning-gear. BENDIX AVIATION CORPORATION. July 14, 1953 [Aug. 11, 1952], No. 19541/53. Class 7 (5). [Also in Group XXIV] In an engine starter drive comprising a power shaft 1, a driving head 2 fixed on the latter, a driving overrunning clutch member 12 connected to rotate with the head 2, a screwshaft 5 slidably journalled on the power shaft, a driven clutch member 15 threaded on the screwshaft, yielding means, such as a spring 19, normally holding the clutch member in engagement, a pinion 9 slidably journalled on the power shaft and drivably connected to the screwshaft 5, means, for example a ring 27, for limiting relative longitudinal movement of the pinion and screw shaft, and yielding means, such as a spring 32, for holding the pinion in extended relation with respect to the screwshaft, an abutment 39 is provided on the power shaft 1 to define the operative position of the pinion. The screwshaft is provided with tongues 6 that engage slots 7 in the hub 8 of the pinion 9. The clutch member 12 which has projections engaging slots 23 in a barrel 16 is slidably and rotatably journalled on the screwshaft 5 and has clutch teeth 13 for engaging similar teeth 14 on the clutch member 15, which latter is in the form of a nut threaded on the screwshaft 5. The barrel 16 is fixed at one end to a flange 4 on the head 2, the other end 18 being inturned to embrace the clutch member 15. A cylindrical block 24 of rubber or similar material is located between the flange 4 and the clutch member 12, the slots 23 being arranged to cause member 12 to maintain the block 24 under an initial compression. Relative movement between the pinion 9 and screwshaft 5 is limited by the ring 27 seated in grooves 28, 29 in the tongues 6 and hub 8 ; an annular weight 31 is splined on the hub and yieldably urged against the ring 27 by the spring 32, which spring also acts to effect engagement of the pinion and engine gear after tooth abutment has occurred. The screwshaft is provided with two shoulders 34, 35 which co-operate with a spring-loaded detent 36 ; shoulder 34 prevents drifting of the parts from the idle toward the meshing position and shoulder 35 only permits demeshing of the pinion when sufficient speed has been attained to enable the detent to be centifrugally withdrawn.

Title: Furnace workpiece support beams
IPC: F27B9/20
Filed: 1978-12-07
Abstract: The invention relates to furnaces and in particular solid hearth walking beam furnaces and support beams thereof. The support beam has a billet support surface (11) raised above an upper refractory layer (19) and extending longitudinally along the beams. The support surface, along most of its length, is narrower than the beams to achieve as even and rapid a heat input to the billet as possible and has along part of its length a meander or zigzag, such that the area of contact on the underside of the billet is changed each time a walking beam stroke is effected. The support surface may be defined by lateral surfaces (21, 22) extending at an angle to the upper refractory layer, the angles varying along the length of the support surface by virtue of the meander of the latter. Scale shedded from the billet during operation of the furnaces is caused to move along the angled surfaces into specific areas where arrangements can be made to collect and dispose of the scale. <IMAGE>

Patent GB-2032415-A (GB)
Title: Sponges for Use in Removing Seams from Clay Handles
IPC: B28B11/18
Filed: 1979-09-24
Abstract: Cup handles made from clay have their seams removed by the handle being pushed along a passage (29) of appropriate cross-section in a sponge (28). The sponge is washed after use by the introduction of water into the passage and by squeezing the sponge. The invention provides for the outer surface (34) of the sponge to be treated all over to render it at least substantially impermeable to water. In use, when the sponge is squeezed, water is expelled only from the passage, and thus the uncontrolled flow of water encountered with sponges having permeable outer surfaces is avoided. Rigid plates (30 and 31) may cover those parallel faces of the sponge into which the ends of the passage open, the plates having slots (32) aligned with the ends of the passage. The sponges may be incorporated in a handle de-seaming machine operating cyclically. <IMAGE>

Title: Digital Planetarium Display System
IPC: G09B27/00
Filed: 1979-11-01
Abstract: A system is disclosed for providing a planetarium display from digitally stored data. A memory (M) contains digital data on stars and planets specifically representing such characteristics as location, intrinsic luminosity, colour and motion patterns, as related to time. A picture system (12) generates a selected display with respect to a selected viewpoint, which viewpoint may move in the universe to afford a dynamic display. Optical distortions resulting from projection on a spherical surface are corrected by electronic means (30, 39) in the data signals and colour is introduced by a colour control unit (C) to add another dimension to the display. The system incorporates data processing capability to indicate motion patterns of stars, not only to provide a dynamic display but also to indicate future or past relationships between individual stars. The system also affords special effects, accomplished as by computer- graphics clipping techniques, to realistically display planets. <IMAGE>

Title: Converting Sequentially Produced Light into Output Light Comprised of Periodic High Amplitude Pulses
IPC: G02B6/00
Filed: 1980-07-24
Abstract: A steady light beam 11, such as continuous wave, constant amplitude coherent light as provided by a laser 10, is passed into a solid body 17 of light transmissive material at 22 while moving through a given acute angle at a given frequency such that the initially received light in the body when the beam starts its movement through the acute angle follows a first path of a first given length before it emerges from the body at 23. Subsequently received light in the body when the beam has completed its movement through the acute angle, in turn, follows a second path of a second given different length before it emerges from the body at 23. The referred-to frequency is adjusted to define a time increment, for the beam to move through the referred to given acute angle, which is made equal to the time it takes light to travel a path length in the body equal to the difference in the referred to first and second given lengths. With such an arrangement, the light beams entering the body at the extremes of the acute angle will emerge from the body coincidentally in time thereby resulting in a high amplitude pulse. These high amplitude pulses are generated at the frequency of movement of the beam through the referred to acute angle. A similar effect is achieved using a plurality of individual pulse lasers (see Figures 4-9 not shown) arranged to be successively triggered at predetermined time intervals. <IMAGE>

Title: Sole tread patterns for running shoes
IPC: A43B5/00
Filed: 1981-02-06
Abstract: Soles for athletic shoes include cleats (24) arranged with gripping edges in the arch and heel that are perpendicular to the longitudinal axis L1 passing therethrough, whereas in the toe cleats (32) are arranged with gripping edges that are aligned in rows that are perpendicular to a line L4 generally defining the direction of travel while the athlete abducts (i.e. turns toe regions outwardly) his feet during the propulsion phase of running. Cleats (34) in the ball portion of the sole fan out to provide a smooth transition from the cleats in the arch to the cleats in the toe. The cleats may be disposed throughout the sole in rows which maintain a perpendicular relationship relative to the longitudinal axis L1 of the heel, but the orientation of the gripping edges of the cleats in the toe and ball portions are varied in such manner as to compensate for the aforementioned abducting effect. Instead of comprising discrete cleats, each row may comprise a single bar-like cleat. <IMAGE>
