Title: Improvements in or relating to a support construction for an excavator
IPC: E02F9/08
Filed: 1969-05-23
Abstract: The ground-contacting surface of an excavator chassis normally supported on the ground at one end by a pair of undriven wheels 15 and at the other end by feet 18 can be increased by securing a dish or trough-like shell to each wheel or foot. Preferably, each shell comprises a circular, downwardly curved dish 20 having peripherally spaced, upstanding struts 21. Each strut has at the upper end an inwardly projacting arm 22 carrying a threaded clamping spindle 23 that can be screwed down to bear on a foot 18 to cause the shell to be clamped to the foot. Each shell also has two upstanding parallel plates 25 for embracing the sides of a wheel when a wheel is entered on to the shell. The struts of each of two diametrically opposed pairs of struts are connected by cross-strips following the peripheral curvature of the shell. These cross-strips prevent a wheel embraced by the plates 25 from rolling out of the shell. These shells facilitate sliding of an excavator over the ground and improve the stability of an excavator when it is crossing or descending into a trench.

Title: Portioning device for doughy material
IPC: A22C11/02
Filed: 1971-05-08
Abstract: A hopper supplies doughy material to a rotary gear pump which may also be supplied with liquid, and the rotary gear pump pumps the supplied material through an outlet. A constantly rotating crank mechanism drives the pump through a driving mechanism including two one-way clutches or free-wheeling devices, arranged to permit rotation in respective opposite directions. One one-way clutch allows driving of the gear pump in only one direction, and the other one-way clutch is interposed between the pump drive shaft and a fixed portion of the device to prevent reverse rotation and backlash of the pump. A connecting rod included in the crank mechanism is connected to a slide which is radially adjustable of a constantly rotating crank disk, and the position of the slide is adjustable by a threaded spindle which is driven, through bevel gearing, by a shaft extending through a tubular drive shaft for the crank disk. A differential gearing is interposed between the tubular shaft and the drive shaft for the threaded spindle, and is adjustable by a manually operable adjusting wheel to set the magnitude of the portions delivered by the pump during each stroke of the crank mechanism.

Patent ES-405592-A1 (ES)
Title: Prismatic lenses for lighting fixtures
IPC: F21V5/00
Filed: 1972-08-05
Abstract: A prismatic lens for an overhead lighting fixture is formed from a transparent material and has a lower face composed of a plurality of arcuate surfaces arranged side-by-side. These surfaces form convex magnifying segments or lenticules in the lens. The opposite or upper face is composed of a plurality of V-shaped depressions extending downwardly from a generally flat intervening surface. The depressions are located behind and centered relative to the arcuate surfaces, whereas the intervening surfaces are positioned directly behind the junctures of adjacent arcuate surfaces. The prismatic lens diverts light rays emanating from a light source behind it primarily into zones disposed oblique to the lens so that the intensity of illumination is minimal in the reflected glare zone located directly beneath the lens and in the direct glare zone located generally to the side of the lens, but is maximum in the oblique zones located between the reflected and direct glare zones. This distribution provides the most pleasant and comfortable illumination for most visual observations performed beneath the fixture.

Title: Flat-flame gas burner
IPC: F23D14/56
Filed: 1977-02-08
Abstract: A fuel gas burner adapted for mounting in a heat treating furnace and for generating a relatively large expanse of radiant energy toward an object to be heated or heat treated. The burner has a housing with separate inlets for fuel gas and air and an air plenum with a forwardly facing throat. Surrounding the plenum throat is a combustion block formed of refractory material shaped to define a forwardly-facing frusto-conical heat radiating surface. A central fuel gas supply tube coaxial with the plenum throat has a nozzle element and a cooperating distributor mounted on its forward end to define with the plenum throat an annular air passage and a fuel gas chamber communicating with the supply tube. The nozzle element has radially extending circumferential vanes that define with the plenum throat, swirl producing slots adapted to receive air from the plenum chamber through the annular passage and fuel gas through ports communicating with the fuel gas chamber. The resulting fuel-air mixture which has a swirling motion imparted by the slots is ignited and propelled radially outward against the frusto-conical surface of the combustion block to produce a generally flat-flame. This produces a relatively large expanse of heat radiation directed toward the area to be heated.

Title: Method for securing winding components in the slot of a rotary electric machine
IPC: H02K3/48
Filed: 1977-11-15
Abstract: A method of securing one or more insulated winding components in the slots of a rotary electrical machine against any displacement during operation in which one or more inserts which have a deformable and heat-hardenable characteristic such as is established by a fibrous material impregnated with a heat-hardenable resin in the B-state, are inserted in the slot in contact with the adjoining side of a winding component. The winding components and non-hardened inserts are then subjected to pressure to effect a deformation matching any tolerance irregularity in the profile of the adjacent surface of the winding component, this step being followed by a gradual heating of the inserts while still under pressure so as to harden the same, and the entrance to the slot is then closed in the usual manner by insertion of a wedge.
