Patent EP-0064737-A2 (EP)
Inventor: LACKINGER ERNST
IPC: B29C65/08
Filed: 1982-05-07
Abstract: In the ultrasonic welding process according to the invention, an additional element 3, besides the ultrasonic welding probe (2), is used as a holding-down device which vibrates at the same ultrasonic frequency as the ultrasonic welding probe 2 but with reduced amplitude, is in contact with areas outside the bearing surface of the ultrasonic welding probe 2 and dampens these externally located surfaces or parts or masses which are in contact with the ultrasonic welding probe itself or lie directly next to the bearing surface of the ultrasonic welding probe 2. Thus areas or parts of the object to be welded which protrude and/or have a relatively large mass and/or areas with a small wall thickness are prevented from fracturing or breaking off or the object to be welded is prevented from being detrimentally affected during the welding operation. Furthermore, an apparatus for carrying out the process according to the invention is specified, the additional element 3 being arranged in the interior of a hollow ultrasonic welding probe 2. The disadvantages with regard to the vibration behaviour of the ultrasonic welding probe which occur when bores are formed in the wall of the ultrasonic welding probe are avoided by the bores being sawn from the welding surface or towards the welding surface and by the welding surface of the welding probe being split up into welding-surface segments. <IMAGE>

Abstract: Single shaft, barrier-type extruder having wide helical passages and adapted to produce plug flow in the solid resin and drag flow in the melted resin. The solid resin particles are compressed (at 30) to a pressure near the requirement of the die apparatus, by a grooved barrel (Figure 3), solids feed stage. The solids passage in the barrier region has width that corresponds to the width of the soiled passage from the pressurization stage (30), enabling effective transmission of conveying pressure through a relatively undisturbed, compact column of solids. The melt passage has similar width and increases in depth along t' j length of the barrier to approach drag flow conditions. Mixing of molten resin with a neutral pressure gradient is achieved with a special array of pins (62, Figure 6) that provide sufficient forwarding to overcome mixing losses. A homogeneous melt of uniform temperature and viscosity can thus be achieved at high flow rate despite large back pressure.

Abstract: A spray mixing nozzle and a method for reacting an acidic fluid and a basic fluid by using the spray mixing nozzle. The nozzle includes a central channel, at least one intermediate annular channel surrounding said central channel, an outer annular channel and a mixing chamber having a generally cylindrical upper section, a generally conically- shaped lower section and an axially aligned discharge orifice. The acidic fluid and the basic fluid are directed through the central channel and the intermediate annular channel into the upper section of the mixing chamber at relatively low velocities and a pressurized gas is simultaneously directed through the outer annular channel into the upper section of the mixing channel at a relatively high velocity, The high velocity gas acts to strip apart and at least partially atomize the acidic fluid stream and the basic fluid stream in the upper section of the mixing chamber. The gas and the partially atomized fluids are then subjected to a high degree of turbulence in the lower section of the mixing chamber and thereby substantially completely atomized and mix the fluids. The mixed and atomized fluids then begin to react and form a powdery or highly viscous paste product which is discharged from the discharge orifice.

Abstract: A paper is a unitary structure but has more than one layer. The layers are of respective different fibres. The paper is made by applying a second slurry to a first slurry at a time when both layers have a consistency which is primarily liquid but the first is less liquid than the second. The second slurry is applied to the first so as to provide a disturbance at an interface between the surfaces of the layers. This application of the second slurry is carried out under predetermined conditions of angle, distance, rate and consistency having regard to the conditions of the first slurry when the second slurry is applied so as to control the extent of disturbance in the interface between the layers and hence the degree of intermingling and interlinking in the interface region. This ensures the bonding together of the layers irrespective of the nature of the material of the slurries. 
     The process allows the strength of the paper at the interface to be at least as great as that in either of the two layers. Thus this is particularly suitable for forming a battery separator having a density gradient across it.

Abstract: A punch blade (72; 80) depresses the coupling heads (79) of a length of successive filamentary coupling elements (76) toward a knockout blade (39) while sandwiching stringer tapes (43, 44) between upper and lower grippers (55, 56, 21, 22). The punch blade (72; 80) is lowered until lower legs (78) of the coupling elements (76) are cut off by cutter blades (31, 32). The punch blade (72; 80) and the knockout blade (39) are then lifted while gripping the severed coupling elements (76) therebetween to forcibly remove the coupling elements (76) out of engagement with sewing thereads (77) on the stringer tapes (43, 44). The upper grippers (55, 56) have confronting steps (61, 62) for engaging the sewing threads (77) so that the severed coupling elements (76) can be detached reliably and smoothly from the stringer tgapes (43, 44) without unduly tensioning the sewing threads (77) and stringer tapes (43, 44). The punch blade (80) may have a vertical reinforcement member attached to at least one side edge thereof and having a lower tooth (86) projecting downwardly beyond a lower edge (84) is pressed against the coupling elements (76), the lower tooth (86) enters between adjacent coupling elements (76) to position the coupling elements (76) against unwanted longitudinal displacement with respect to the punch blade (80).

Abstract: Several types of hand held printing implements are disclosed for marking characters such as crosses on game coupons such as Lotto and football pools.The first type prints the character on the top coupon ply and replicates the character on the carbon copy. This type has a hollow tubular body (2, 8), a reciprocable printer core (16) inside the body, a print head (15) at a leading end of the core, a spring (30) which stores a print strike force when the body and core slide to a predetermined position and a trip device (34, 30) (50, 52) (32,62) (66,74,76) (96) which fires the core when the print strike force reaches a predetermined magnitude. The print head (15) has a hollow punch part for replicating the character in addition to a part (17) for printing the same. A guide tip (14) enables the user to preposition the print head before printing.In other versions of this type the print strike force is supplied by a slidable striker (82) or a finger pad (92) operated by the user's finger.The second type also has a guidetip (14) for prepositioning the print head but merely prints without replicating the character.

Abstract: A display unit for merchandise which is stored standing inside the unit strapped between a base tray and a lid tray, capable of being stored, transported and offered for sale via the topside, comprised of paperboard but, folded and glued in such a fashion as to form a block-shaped case. The case has a smooth lower section in which the merchandise can be stored with little lateral play between the side walls and the base tray. The side edges each display two v-shaped notches so that in a first section the side walls can be folded inwards and in a second section above said first section the side walls can be folded outwards approximately horizontally and a top section with vertical sides leading on from the second section. Plastic holders with fingers pointing inwards and a protective surface pointing downwards are slotted through an aperture near the folding line between the second section and the top section. In the first section where the fold slopes inwards, there are two lugs cut, respectively, below the protective surface. A rubber band is hooked into each of these lugs, led behind the protective surface and up along the outside surface of the top section where it is hooked onto a retaining tongue of the plastic holder. The lower edge of the lid terminates on a level with the inward fold of the first section.
