Inventor: KUPFERT B
IPC: F16J15/34
Filed: 1960-04-26
Abstract: 879,754. Lapping seal rings. CATERPILLAR TRACTOR CO. Feb. 18, 1960 [Dec. 14, 1959], No. 5745/60. Class 60. [Also in Group XXVI] A seal ring 46, which may be of "Stellite" (Registered Trade Mark), for a mechanical seal (see Group XXVI) is first lapped to form a relieved portion 54 and a flat radial band. The ring is then held in a rotatable chuck 48 by an elastic material torus 52, identical to that to be used in service, and lapped under substantially the same axial pressure to which it will be subjected in use, for example 100 pounds, on an annnular internal frustoconical surface 44 of a circular table 40 freely rotatable on a spindle 42. This results in an external frusto-conical surface, Fig. 10, which, when the axial pressure is relieved from the ring, forms an internal frusto-conical sealing band 36, Fig. 11.

Title: Rail fastening on concrete ties or the like by means of resilient tension clamps
Inventor: SCHULTHEISS HANS
IPC: E01B9/48
Filed: 1990-05-29
Abstract: The invention concerns a rail fastener on concrete ties (4) or the like including resilient tension clamps (6) of steel rods in the form of a W and angled guide plates (3) for the rail base (1a). This so-called HM rail fastener is inventively improved by a special shaping of the tension clamp and angled guide plate, to simplify the securing of the rail on the concrete ties, in that the rotation of the elastic strainers which was previously necessary in HM construction when passing from the preassembly to the assembly position is omitted. This is achieved in that the angled guide plate (3), which is provided with a rib (3a) extending longitudinally to the rail foot for abutment on the rail foot (1a), contains in this rib special recesses (3b) for the reception and retention of the free ends of the tension clamp in the preassembly position. A tension clamp (6) has outer legs (6b) which with expansion of the spacing from the inner legs (6d) against the rail foot (1a) become broader and their free ends (6a) end outside the middle portion (6e) and wherein the inner legs (6d) of the tension clamp (6) which surround the tie screw (5) are designed so that in the preassembly position they abut with their center portion (6e) the shaft (5a) of the tie screw, while the head (5b) of the tie screw (5) overlaps the inner leg (6d) in the assembly position. In a special embodiment, the tension clamp is so designed that its center portion permanently surrounds the tie screw (5), and its inner leg portions are brought together except for a small spacing.

Title: Aspirated syphon shoe
Inventor: TIMM GERALD L
IPC: F04F10/02
Filed: 1991-04-10
Abstract: A low differential pressure rotary syphon for the purpose of removing condensate from the interior of a heated dryer drum under low differential pressure conditions. The reduction in the magnitude of differential pressure required to remove the condensate is accomplished through the direct introduction of steam into a central plenum area receiving condensate thereby reducing the mass density of the condensate mixture. The reduction in mass density and the steam introduced acting directly on the condensate within the central plenum area facilitates the removal of the condensate from the drying drum interior. <IMAGE>

Filed: 2002-08-31
Granted: 2005-08-31
Abstract: A juicer arrangement is provided in the form of a motor-driven domestic appliance capable of extracting the juice from fruits, typically citrus fruits, and delivering the juice into a vessel positioned adjacent the main body of the appliance. In order to promote clean transfer of the juice into the vessel, and/or resist a tendency for the vessel to be moved away from the main body by reactive forces associated with start-up of the motor, the appliance is provided with a resiliently-loaded outlet duct for the juice which engages with an opening in a lid or cover of the vessel. Preferably, the outlet duct is a substantially straight and hollow tube supporting an outer collar that is spring-loaded for outward axial motion relative to the tube; the collar and/or the tube are retained together to prevent unwanted disengagement of the collar from the tube.

Granted: 1982-12-15
Abstract: An analog quartz wristwatch movement comprises a base plate (10) with a recess to receive a power source (battery) (29), an electromechanical transducer (stepping motor) having a coil (22), a wheel train arranged generally centrally and around part of the periphery of the battery (29), a circuit board (12) carrying electronic components, and a battery retaining spring (37) (serving as the negative contact of the battery) which is secured (by a screw 38) at a position between the yoke (24) of the electromechanical transducer and the battery (29), the position at which said retaining spring (37) is secured being located closer to the centre of the wristwatch movement than one of the positions at which said electromechanical transducer is secured (by a screw 26a).

Title: Heat exchanger having a bundle of parallel tubes and method of assembling its component parts
Inventor: CADARS PATRICK
IPC: F28F9/16
Filed: 1982-09-09
Granted: 1985-05-30
Abstract: The heat exchanger (10), e.g. a motor vehicle radiator, has a bundle of thin-walled metal tubes (12) passing through a perforated plate or collector (18) via holes (23) therethrough. The collector plate is made with holes having walls that are highly elastic, either by the collector being molded from a highly elastic plastic, or by the collector plate being made from a sheet of metal with the holes being formed with spring shaped rims. The elasticity is used to grip and seal the tubes (12) in the holes (23) through the collector plate, and the relative strengths of the tubes and the plate are such that the portions (38, 61, 92) of the tubes thus elastically gripped in said holes are contracted by the elastic grip and are flanked on either side by non-contracted portions (42, 41; 66, 74; 93, 94) of tube which ensure that the tubes are held fast against longitudinal movement in either direction relative to the collector plate.
