Title: Device for conveying samples to a gluing station
Inventor: NEUBERG JOACHIM
IPC: B65H3/22
Filed: 1989-03-04
Abstract: A device for conveying samples, which can be picked up by suction or by spiking, from magazines to a gluing station. The device is intended for use during the production of sample cards. It has a group of perpendicular magazines which are arranged next to one another and are open at the top for receiving in each case one stack of samples. A corresponding group of lifting cylinders below the magazines ensures that the magazines are raised in each case by the height of one sample. A transfer table has, on its lower side, holding sections for receiving the samples. A transportation device serves for lifting, lowering and advancing the transfer table to the gluing station. The samples are provided there with glue on their underside, are released by the transfer table and preferably pressed directly by the latter onto a sample board. Depending in each case on their type, the samples can be sucked up by the holding sections or picked up with the aid of needles. <IMAGE>
Patent DE-3908219-A1 (DE)
Title: Process for heating injection-moulded parisons, taken from a supply, for subsequent inflation into hollow bodies in a blow mould and apparatus for carrying out the same
Inventor: ROOS UWE-VOLKER
IPC: B29C49/06
Filed: 1989-03-14
Abstract: In the heating of injection-moulded, cold parisons, taken from a supply, which are heated to blowing temperature on a conveyor and, after running along the conveyor, are fed to a blow mould, there is the risk that the only externally acting heat does not spread adequately over the cross-section, so that the inner wall does not reach the required blowing temperature. In order that this temperature is reached, the heat fed to the outer wall must be considerably above the required blowing temperature. Since in the case of PET, for example, this entails the risk of recrystallisation due to overheating, it is known for cooling air to be blown against the parisons at the same time as they are being heated by infrared heaters. The invention improves this uncertain process by initially heating the parisons when running along the conveyor to a temperature (Tmax1/Tmin2) below the blowing temperature (TBL), then cooling them and, following cooling, heating them again to a temperature (Tmax3/Tmin3) which is just above the blowing temperature, after which, to equalise the temperature of the outer wall (wa) and of the inner wall (wi) at the blowing temperature, they are left alone on the conveyor or cooled slightly. <IMAGE>

Title: Device for bending cylindrical materials into spiral shape - by feeding material to rotating former by grooved roller which moves along axis of former
Inventor: PULZER GUENTHER F
IPC: B21D11/06
Filed: 1989-04-14
Abstract: The machine consists of: (i) a rotating cylindrical former; (ii) a clamping system for securing the material being bent at one end of the former; and (iii) a roller with a circumferential groove whose axis is at an adjustable angle to the axis of the former and which can be moved along the former by a CNC control system so as to guide the material being bent onto the former in the required spiral shape. The clamping system is in the form of a disc fixed to one end of the former, and is controlled by the same CNC system as the feed roller. A bushing is fitted to the other end of the former, and can be removed in order to allow the bent material to be taken off the former. When tubular materials are being bent, an internal support may be used inside the tube upstream of the point of contact of the tube with the former. USE/ADVANTAGE - Used for bending cylindrical metal bars or tubes into a spiral shape, such as in the manufacture of cooling coils etc. The proposed system produces the required shape in a single operation, and allows a high degree of accuracy to be achieved. The angle of the spiral may also be varied from point to point during the forming process.

Title: Battery stapling machine - has staples driven by piston sandwiched between energy-storing flywheel and pressure wheel moved relatively under control of timing
Inventor: KERRIGAN JAMES E
IPC: B25C1/06
Filed: 1990-12-18
Abstract: The stapling machine drives staples (19) or similar fasteners into material using a piston (36) coupled frictionally to an energy-storing flywheel (24). The piston is driven along an ejection channel (114) from which he stape is ejected. The piston is returned to its original position by a return mechanism. The piston occupies the gap (140) between the flywheel (24) and a pressure wheel (26) opposite. - The flywheel and the pressure wheel can move towards and away from another in order to engage and disengage the piston. A timing circuit controls the drive that moves these two wheels relative to one another. A locking mechanism keeps the two wheels in contact with the piston once the timing circuit has initiation their contacting motion. The locking mechanism is unlocked as the end of the piston emerges from the gap.
