Patent ES-406376-A1 (ES)
Title: Method of making bottom seal thermoplastic bags
IPC: B31B23/00
Filed: 1972-09-04
Abstract: According to the present disclosure a method is provided wherein tubular thermoplastic material is intermittently fed between opposed transversely extending seal bars operating in timed relation with the intermittent feeding of the web to sequentially perform cutting and sealing of the web during its period of repose. To insure a clean straight transverse cut, which occurs momentarily before transverse sealing, the web is held under tension between longitudinally spaced draw and feed rolls. Immediately after the web is transversely severed, the seal bars are brought into pressure engagement transversely sealing the web along a margin which will define the bottom of the bag. While the sealed portion of the web is at the sealing station, cooling air is discharged along the sealed portion of the web to effect cooling. Before the web is fed an additional increment, it is momentarily fed rearwardly to avoid the possibility of adherence to the seal bars.

Title: Dual amplitude vibration generator
IPC: E01C19/28
Filed: 1974-04-30
Abstract: A vibratory compacting machine having a dual amplitude vibration generator by which either high amplitude or low amplitude vibration is selectively imparted to the drum of the machine. The vibration is produced by primary and secondary eccentric weights carried by a power driven shaft inside the drum. The primary weight is fixed to the shaft and the secondary weight is mounted to swing about an axis parallel to and spaced from the shaft, between a retracted position in which the primary and secondary weights are so disposed with respect to one another that the amplitude of vibration is high, and a projected position in which the secondary weight partially counterbalances the primary weight and the amplitude of vibration is low. Solid rubber torsion springs incorporated in the pivotal connection between the weights yieldingly hold the secondary weight in its retracted high amplitude position from which it is swung by centrifugal force if not positively restrained by the activation of a locking device that includes a manually shiftable control rod axially slidable in the shaft.

Patent ES-452040-A1 (ES)
Title: Method of making a gasified confection
IPC: A23G3/34
Filed: 1976-10-01
Abstract: This invention relates to incorporating a gas into a hot candy (sugar) melt within a pressure vessel at superatmospheric pressure. The gasified hot melt is transferred from the pressure vessel to a cooling tube, through a line or lines connecting the bottom of the pressure vessel to the bottom of the tube, by creating pressure differential between the cooling tube and the pressure vessel while venting the top of the tube to the atmosphere. When the transfer is complete, the cooling tube is isolated and the pressure within it is maintained at superatmospheric and it is cooled to a temperature below 70 DEG F. whereby the gasified hot melt becomes a gas-containing solid matrix. Next, the cooling tube is shock-treated so that the gas-containing solid matrix is shattered into multiple fragments.

Title: Fluidic transducer access opening in a stack of flexible record disks
IPC: G11B17/02
Filed: 1976-11-18
Abstract: Selectively altering air flow generates an access opening for a record surface on one of a large plurality of flexible record storage disks coaxially supported on a common spindle for rotation. Air flow through the interstices between the disks usually is sufficient to stabilize rotation of the disks. To generate a transducer access opening the air flow on one axial side of a record disk to be accessed, which includes a record surface, is altered in a manner that disks axially adjacent and facing the record surface tend to axially move together at their periphery, resulting in a peripheral transducer access opening adjacent a stabilized record disk. In a preferred form of the invention, the axial extent of the altered air flow is limited to a predetermined portion of the stack of disks for minimizing the volume of air flow change. For dual sided recording, the air flow is altered at either side of the record disk to be accessed.
