Title: Sliver opening device for open-end spinning mechanism
IPC: D01H4/32
Filed: 1972-08-04
Abstract: The highspeed picking roller is driven by a friction drive wheel engageable with a belt having one end carried by a pulley on the highspeed picking roller shaft and the other end carried by an idler roller mounted on a lever to swing the idler roller and belt out of engagement with a friction drive wheel. The lowspeed sliver supply roller of the sliver-resolving mechanism for an individual spinning station is quickly disengageable from a common drive for a plurality of spinning stations by sliding a drive belt off a single-flange pulley. Alternatively, gear wheels on the supply roller shaft and the main drive shaft are connected by an intermediate idler gear having its axis offset from a line through the axes of the drive and driven gear wheels and the intermediate gear wheel can be swung by a lever out of meshing engagement. Upon disengagement of at least the picking roller from its drive, a side of the resolving mechanism housing can be removed by loosening thumbscrews, and internal components mounted in tapered bores in the opposite housing wall can be pulled quickly from the housing. The entire housing is connected only to the machine frame and can be removed independently of the spinning chamber housing.

Patent ES-454154-A1 (ES)
Title: Elevator system
IPC: H02P3/04
Filed: 1976-12-10
Abstract: An elevator system including an elevator car to be stopped at a predetermined stopping point from any initial speed below a predetermined maximum value, at a predetermined uniform rate of deceleration. The uniform rate of deceleration determines the desired speed versus distance-to-go reference pattern, which is initiated at a predetermined fixed distance from the stopping point. If the car speed is at the maximum value, deceleration will be initiated immediately. If the car speed is below the maximum value, the car is allowed to continue at the same speed until the car speed and location of the car relative to the stopping point match a point on the reference pattern. This point is accurately determined via digital feedback and comparison circuits which start the elevator car on the desired deceleration speed pattern with zero error. When the point on the reference pattern is reached, digital control circuitry including an up-down counter provides an error count for an actuator which controls the deceleration of the car to closely follow the reference pattern.

Patent ES-461978-A1 (ES)
Title: Nodularizing treatment employing unitized modifying agent
IPC: C21C1/08
Filed: 1977-08-30
Abstract: A method and apparatus is disclosed for conditioning a charge of molten cast iron, which would normally solidify with a flake graphite structure, to produce partial or total spheroidal graphite cast iron. In addition, the method and apparatus can be used to further condition a partially conditioned cast iron to yield a partial or fully spheroidal graphite cast iron. A recess is provided in the metal flow system (within or without the mold system) leading to the casting cavity or cavities. The recess has a shape and cross-section (taken in directions normal to the direction of flow of the molten charge) such that the spheroidizing agent dissolves uniformly when the molten iron flows over it to achieve unprecedented homogeneity. A dense solid unitary block of spheroidizing or nodularizing agent, substantially devoid of MgO interiorly thereof, is typically snugly fitted in said recess and mates with the side walls and bottom of said recess. The block typically presents a substantially constant and uniform interface with the molten charge during all stages of conditioning and pouring however, a deviation in the interface area may be designed into the block to compensate for molten iron temperature variations or molten iron flow rate variations when the casting technique experiences unusually high variations in the ferrostatic pressure head. A relationship is disclosed between charge weight, charge flow rate, magnesium concentration in the spheroidizing alloy, and interface area so as to determine a desired degree of nodularity in the final casting and/or to design a solution rate compatible with a specific casting technique. The residual magnesium can be reliably maintained at a level sufficient to consistently obtain full spheroidal graphite shape. A preferred magnesium level is 0.020% to 0.040% of the weight of the casting but higher or lower levels can be reliably obtained if required by base metal chemistry. This is significant since the prior art has been unable to reliably obtain full nodularity with 0.02-0.025% residual magnesium under commercial conditions.

Title: Conveying goods through processing machines
IPC: B65B35/26
Filed: 1979-10-11
Abstract: A plate 5 rotates step-by-step, bringing a plurality of seats 6 in succession over an elevator member 21. Each seat accommodates a product P and when each seat stops over the elevator member 21 the member 21 rises to grip the product and a wrapper Z against a counter elevator 22. The elevator member and the counter-elevator then rise together, the elevator member passing through the seat 6, to transfer the product to a wrapping station S. To increase the production rate of the machine, the plates does not wait until the member 21 has withdrawn from the seat 6 before the plate carries out its next increment of rotation. Instead the elevator member 21 moves with the seat 6 as the plate 5 rotates, carried on a slide 37 movable along rods 37. Thus withdrawal of the elevator member can take place while the plate 5 is rotating.
