Abstract: Electromagnetically Operated Hydraulic Valve Device With Snap-Together Valve Housing Abstract The present invention comprises an electromagnetically operated hydraulic  valve  device  (10)  providing  an  almost instantaneously responsive displacement of a ball valve (60) in order to effect fluid flow  relative  thereto.   Hydraulic valve  device  (10) comprises  a generally cylindrical  housing (12) having one end (16) open and a bushing (19) extending from the other end (18), with a plurality of longitudinal openings (14) disposed about the perimeter of housing (12).  A cylindrical bobbin (30) having an interior through opening (32)  is disposed within housing  (12) and supports an electrical winding (34), with a core member (20) enclosing the open end (16) of the housing and having a circular post (22) extending Into the bobbin opening (32).  A nonmagnetizable sleeve (38) is located within the Interior of bushing (19) between the bushing and a cylindrically shaped armature (36). One end (37) of the armature has an opening disposed opposite a complementary shaped opening (21) In the end of post (22), a spring (39) being received therebetween.  An outer valve casing (40) is disposed over housing bushing (19), the outer valve casing having an interior cavity (45) with a groove (48) disposed in the wall of cavity (45).  An Inner valve casing (70) having a circum-ferential  boss (74) about the perimeter of the casing is fitted within the Interior cavity (45) by means of a leak resistant, snap-together engagement of the circumferential boss (74) and groove (48), and a glass ball valve (60) Is captured within a subinterior cavity (75) In the Inner valve casing.  Ball valve (60) is held in sealing engagement with valve seat (45) by means of a free-floating drive pin (50), the other end of drive pin (50) abutting against armature (36).          Energization  of  winding  (34)  effects  an  almost  Instantaneously responsive displacement of armature (36) whereby ball valve (60) is displaced and engages valve seat 72,  relative to valve seat (45) and fluid flow effected thereby.

Abstract: ABSTRACT OF THE DISCLOSURE     A thermoelectric device exhibiting both structural integrity and decreased stress across the device notwithstanding the application of thermally cycled temperature differentials there-across includes, electrically interconnected thermoelectric elements and a rigidly affixed substrate.  Thermal stress is relieved by using flexible conductors to interconnect the thermo-electric elements, and by the use of a flexible joint to attach a second substrate to the remain-der of the device.  Complete elimination of the second substrate may also be used to eliminate stress.  Presence of the rigidly affixed substrate gives the device sufficient structural integrity to enable it to withstand rugged conditions.

Abstract: BREATHER BAG CONSTRUCTION FOR A      SEALED STORAGE STRUCTURE              Abstract of the Disclosure An improved breather system for a sealed storage structure.  The roof of the storage structure is provided with an opening and a generally cylindrical, vertically disposed, breather bag is located within the structure with the neck of the bag being sealed within the opening.  A cable is attached to the inner surface of the bag at the lower end of the bag and extends upwardly through a series of vertically spaced tubular guides and  exits through the neck of the bag to the exterior.  Each of the tubular guides is connected to the inner surface of the bag by a series of cables.  A storage sleeve can be mounted on the roof in communication with the opening.  By pulling upwardly on the cable, the bag will be drawn upwardly out of the storage structure and into the storage sleeve to a location where the bag will not interfere with filling of the storage structure with a stored material.  After filling, the bag can be released and the bag will expand and contract in accordance with pressure differentials between the atmosphere and the interior of the structure to thereby balance the pressure.  The elongated vertical configuration of the bag provides a substantial increase in breather capacity over that of conventional breather bags.

Abstract: A B S T R A C T     According to the invention it is suggested that, in a heating boiler with vibrating grate (3), a supply pipe (6) from which fuel material in particle form, in particular pellets, is supplied to the grate, is mechanically connected to the grate (3) and arranged to freely support the grate, which is thus freely suspended in the combustion chamber without contact with the bottom and walls of the combustion chamber. A vibrating means (19) is also mechanical-ly connected to the supply pipe (6) and arranged to produce a rec-tilinear movement, as well as. functioning as drive source to feed the fuel particles to the grate via the supply pipe (6). The vi-brating means gives the fuel particles a toss movement obliquely upwards and forwards in the supply pipe and on the grate thus causing the fuel particles to move gradually onto the grate and towards the end of the grate opposite the supply pipe (6).

Abstract: DUAL ALLOY COOLED TURBINE WHEEL AND        METHOD OF MANUFACTURE            Abstract A dual alloy cooled turbine is manufactured by casting a hollow cylinder of first nickel-base alloy material with high creep resistance to produce directionally oriented grain boundaries.  A preform of a second nickel-base alloy material with high tensile strength and high low-cycle-fatigue strength is diffusion bonded into the bore of the hollow cylinder by subjecting the cylinder and preform to hot isostatic pressing.  The resulting cylindrical block is cut into thin precisely flat wafers.  A plurality of alignable holes for forming fluid cooling passages are photochemically etched into the individual wafers.  The wafers then are laminated by vacuum diffusion bonding techniques, with the holes aligned to form fluid cooling passages.  The resulting laminated block is machined to produce the turbine wheel with turbine blades through which the cooling passages extend.

Abstract: ABSTRACT            A pedal crankshaft operated actuator for a bicycle brake has a link, chain or strap clutch actuated by a pilot clutch in the form of a spring wrapping the crankshaft. In one arrangment, the actuator is formed by a yoke having a jaw engageable with one side of the crankshaft, a link pivotally connected to the yoke and having a jaw engageable with the other side of the crankshaft, and a pair of light spring coils surrounding the crankshaft and having a bight engaging the link outwardly of the jaw so that rotation of the crankshaft in a reverse direction locks the spring to the crankshaft and causes the jaws of the link and the yoke to seize the crankshaft. The link folds relative to the yoke to enable the assembly to be inserted into the pedal crankshaft housing, until a lever arm attached to the yoke drops through an aperture in the housing.  In another arrangement, a light weight spring clutch transmits torque from the crankshaft to the lever upon back pedalling, and reaction from the torque causes the lever to tilt and engage a strap clutch locking the lever to the crankshaft as the braking forces are increased.
