Title: Method of assembling a wheel having vanes
IPC: B23P15/00
Filed: 1968-04-04
Abstract: In a method of making an hydraulic transmission wheel comprising an outer shell, an inner shell and a number of vanes connecting the shells, the vanes are each coated with a layer of brazing metal prior to assembly of the vanes with the casings and the assembly is heated to melt the brazing metal. In making an impeller for an hydraulic torque converter for an automobile, curved steel vanes 1 having projections 7, 7 on one edge and projections 9, 9 on the other edge and curved fins 4 are coated electrolytically with copper to a thickness of 0À015 to 0À02 mm. and the vanes are assembled between cleaned steel shells 2, 3 and the fins are assembled between the shell 2 and a shroud 5. The projections 7, 7 on the vanes engage recesses 6, 6 in the shell 2 and the projections 9, 9 pass through slots 8, 8 in the shell 3 and are bent down flat against the shell 3. The assembly is placed in a furnace with the impeller axis vertical and the shroud 5 on the floor and melted copper is drawn by capillary action between the projections and walls of the recesses. Little copper remains on the exposed faces of the vanes and fins. Heating is at 1100 C. in nitrogen or other non-oxidizing atmosphere.

Title: Voltage transformer with removable high voltage fuses
IPC: H01H9/10
Filed: 1968-10-17
Abstract: A transformer is connected to a high voltage supply through a fuse in a removable holder, the removal of which also interrupts the low voltage circuit which may also contain a fuse. The transformer may be disconnectable from the fuse holder container, an interlock being provided so that disconnection can be effected only when the fuse holder is not in position. In the form shown, the transformer casing has a nose 32 containing a contact 17 connected to one end of the high voltage winding, the other end being earthed. A mating contact 16 carried in the housing 1 is connected to a contact ring 7. The fuse 3 is carried at the open sided front end of a holder 8, a contact 12 being held in a clip 15. When the holder is inserted in the housing 1 the sleeve 12 engages a contact 13 connected to a bus-bar which may be oil immersed in an enclosure with a wall 7. Spring contact members 5, at the other end of the fuse, carry contacts 6 which engage the contact ring 7. The interlock between the fuse holder and transformer is provided by members 23, 24.

Title: Coffee dispenser
IPC: A47G19/34
Filed: 1973-01-03
Abstract: A metering dispenser which will automatically measure a quantity of powdered or granular material and which will permit an immediately effective adjustment in metering volume to be made. The dispenser includes a container, a cup within the container sized to permit passage of material therearound and into the top of the container when such is inverted. The cup is open along its top side so that it collects and retains the material in the top thereof when the container is returned to its upright-position and that material begins its descent responsive to the reversion. When the container is again inverted, the material in the cup flows from the cup through a tube and out of the container. Rotation of the tube causes a varying proportion of the cup to be covered by the tube, thus permitting the volume of material passing through the tube to vary responsive to such rotation.

Title: Time fuse
IPC: F42C15/24
Filed: 1974-04-06
Abstract: A time fuse for a non-spinning projectile has a pivoted catch connecting a fuse setting member to a setting disc whereby rotation of the member rotates the disc to wind a clockwork spring.

Title: Fluid pump for a writing device
IPC: F04B53/16
Filed: 1976-12-22
Abstract: A pump mechanism for delivering ink or the like writing fluid from a reservoir to a point of utilization such as a writing device. The mechanism includes a piston slidable in a cylinder for drawing ink into the cylinder during a suction stroke and discharging the ink during a pumping stroke. The cylinder is formed by a cylinder wall which includes a frusto-conical portion tapered inwardly in a direction away from the piston. The piston comprises a single plastic member having a forward end portion which faces and cooperates with the tapered portion of the cylinder wall and which has an outside diameter which is greater than the smallest diameter of the tapered cylinder wall portion, whereby the forward end portion of the piston engages the tapered cylinder wall portion as the piston moves forward during a pumping stroke. The front or forward wall of the piston is recessed to enable the forward end portion of the piston to deform and slidingly engage the tapered cylinder wall in sealing engagement as the piston moves forward in a pumping stroke. The forward end portion moves out of engagement with the tapered cylinder wall portion as the piston moves backward during a suction stroke.

Title: Torsional vibration damper having two part hub
IPC: F16F15/126
Filed: 1977-09-16
Abstract: A torsional vibration damper and method and apparatus for its manufacture. The outer inertia member carries a radially inwardly extending web, the web sandwiched by a pair of elastomer members. A two-piece hub sandwiches the elastomer members, the two hub pieces being held together as by swaging or by rivets. Tooling for the swaging mode of assembly is shown such that the elastomer members are deformed from an original to a final configuration, and the swaging then accomplished with a single continuous movement. The swaging assembly apparatus for the device includes Belleville springs, the apparatus limiting the maximum force applied to that portion of the hub members controlling the assembled elastomer thickness. The damper configuration facilitates low specific energy dissipation and large elastomer-to-metal interface area to thus tend to lower shear stress in the elastomer. In addition, should the elastomer fail in use, the damper inertia mass is mechanically constrained to remain with the hub assembly. The two hub pieces cause radial extrusion of the elastomer, the extruded portions contacting the inertia member, the latter guiding and defining the extrusions.

Title: Deflection unit for a cathode-ray tube
IPC: H01J29/76
Filed: 1979-02-22
Abstract: In cathode-ray tubes which require a precise specific electromagnetic deflection field configuration as for example, in self-converging color television picture tubes, an accurate distribution of the coil windings has to be maintained on the inside of the deflection unit. In practice, this requirement has been met with the aid of toroidal coil windings, but with respect to the more sensitive saddle-type coils this problem has not yet been solved satisfactorily, especially when large numbers of winding turns are to be accommodated. With respect to saddle-type coils the invention proposes to solve this problem by placing the windings into grooves.
