IPC: B65B7/06
Filed: 1976-11-30
Granted: 1979-02-06
Abstract: S P E C I F I C A T I O N                Inventors:  Thomas C. Harris &             Doyle R. Hudson Assignee:   Olinkraft, Inc.             Docket No. BD-232-74 Title:      BAG PUSH-OFF IN-FEED METHOD          Abstract of the Disclosure An improved in-feed method for, for example, the final closing stage of a bag filling machine of the type wherein a plurality of open bags with pre-formed gusseted tops are filled with a load of loose material and the gusseted tops reformed in a rapid sequence, and the bags are subsequently sealed closed.  In the inventive method one bag pushes off the preceding bag in face-to-face engagement therewith along their front and rear sides, re-spectively, whereby the following or pushing bag being fed in is constrained on all four sides before it begins its infeeding move-ment. The four-sided constraint is provided by a multiple-finger pusher in the rear, opposing guides on the sides, and the presence of the preceding bag in front in face-to-face engagement therewith.          Such frontal engagement prevents the load in the intermediate, following bag from shifting forwardly under the foward force fo the pusher and opening the reformed gusseted bag top.          The novel in-feed method takes place at the entrance to the bag closing station and is used in combination with an in-feed mechanism having a pivoted, movable inlet portion which initially presents open, tapered contact surfaces (Figure 3) to the entering bag and subsequently, after a bag enters the device, presents closed, parallel contact surfaces (Figure 4), the contact surfaces continuously  moving in a longitudinal direction along the machine.     The longitudinally moving contact surfaces, formed by moving belts, position, hold and guide the top of the bag (whose gussets have previously been reformed after the bag has been filled) preliminarily to its being closed by heat sealing or, alternatively, by sewing.

Abstract: TITLE:  RESILIENT SPRINKLER RISER     Abstract of the Disclosure A resilient sprinkler riser is described for mounting a pulsating type sprinkler head wherein a nozzle is utilized to direct a spray jet of water in a radial direction from a vertical axis of rotation while a pivoted deflector member operates to rotate the nozzle about the vertical axis.  The riser includes a flexible tube that is coaxially mounted within an elongated closed helical tension spring.  The spring is fastened at its lower end relative to the tube while its upper end is free to slide coaxially over the tube length.  The spring is  pretensioned to hold the pipe in an upright con-dition under the reaction forces exerted by a jet of water exiting through the sprinkler nozzle.  However, the spring tension is not sufficient to hold the tube in an upright condition when excessive external lateral forces are applied.  When this happens, the riser will deflect in the direction of the force.  When the force is removed, the riser will spring back to a normal upright condition.

Abstract: ABSTRACT:                  In X-ray scanners operating with a large number of detectors ("fan scan") the problem exists that reconstruction errors occur in and about the  centre of rotation, which errors are caused by the fact that the radiation absorption in said area is substantially always measured by the same detectors and that the sensitivity of all detectors is not exactly the same.          The invention provides an improvement in that the measurement is carried out with a larger number od detectors than is neces-sary for the measurement of the scanning field and that the de-tector arc pivots about its centre of curvature during the measurement. As a result of this the absorption in the centre of rotation is measured by different detectors of which the different sensitivities, with a sufficiently large number of extra detectors, can be averaged to a considerabl extent.

Abstract: ABSTRACT OF THE INVENTION           Water insoluble adducts are produced comprising the reaction product of a polycaprolactone polyol and an anhydride of a polycarboxylic acid.  The polycaprolactone polyol reacted with the anhydride of the polycarboxylic acid has an average of at least two hydroxyl groups in the molecule, a hydroxyl number of from about 15 to 600 and an average molecular weight of from about 290 to about 6,000. The carboxylic acid anhydride has at least one intra-molecular carboxylic anhydride group.  These water insoluble adducts on reaction with an inorganic or organic base produce water soluble, carboxyl modified oligomer addition reaction products which are eminently suitable for the production of aqueous coatings compositions.  Exceptionally good coatings compositions are obtained when a crosslinker is present in the coating composition.     1.

Abstract: Abstract of the Disclosure An automatic radio direction finding method and apparatus which employs a scanning directional wide aperture aerial system, a receiver, and a computer which effectively simulates the methods of a skilled direction finding operator in determining the direction of arrival of a radio wave using all the pattern information derived from the aerial system.   A representation of the amplitude distribution of the receiver output signal as a function of the direction of maximum sensitivity of the scanning aerial system is stored, and the computer then determines the point about which this distribution is most symmetrical using an algorithm which folds the distribution, in sampled data form, in half, and computes the sum of the difference amplitudes between the overlaid samples.  This procedure is repeated for each of a plurality of different fold locations, and these sums representing the asymmetry of the distribution about the associated fold point, are stored as a function of the fold point to determine the point in the distribution having the smallest sum, ie the greatest symmetry.  This point of maximum symmetry provides an indication of the direction of arrival of the radio wave.

The tape also runs over stationary pins which allow the tape to coil when translated in one direction.  Opposed ends of the tape are provided with aperature which are entered by the pins when one end portion of the tape is nearly uncoiled so that further translation and complete uncoiling of the tape is prevented.  The tape end portion is automatically disengaged from the pins by the inherent coil forming stress in the tape when reverse trans-lation is initiated.

Abstract: ABSTRACT OF THE DISCLOSURE         A timing mechanism for controlling actuation of a switch in a toy gun in order to produce a burst of light of a predetermined duration includes a housing and a switch actuating member movably mounted in the housing for movement between first and second positions.  The switch actuating member is located to engage the switch during a portion of its movement and it is biased to its first position by a spring or the like.  An impeller arrangement is provided for driving the switch control member from its first towards its second position against the bias of the spring;and an inertia element, such as a flywheel, operatively engaged with the switch control member, is driven by the switch control member as it moves from its first position towards its second position.  The inertia element aids in driving the switch control member to its second position and resists return movement of the switch control member, under the influence of the spring, from its second to its first position, thereby to control the duration of time during which the control member closes the switch and thus control the duration of the burst of light produced by the toy gun.
