Patent DE-3113060-A1 (DE)
Title: Charging device for moulds for concrete element manufacture
Inventor: HOERNER JOHANN DIPL ING DR
IPC: B28B13/02
Filed: 1981-04-01
Abstract: The invention relates to a charging device for moulds for concrete element manufacture, preferably of bar-shaped or fine-membered prefabricated concrete parts such as masts, stanchions, bars or reinforced concrete binders. In relation to known technical solutions, the charging device according to the invention makes it a requirement to supply the concrete from a concrete supply system simultaneously through two or more narrow filling slots to the mould(s). This is brought about by the removal of the concrete from the supply system taking place in each case by a transport device consisting of two conveyor belts, the two transport belts of which are arranged at right angles to one another and in a stepped manner one below the other and which are operated with variously adjustable drive. The concrete is removed in full opening width from the supply system by the removal belts of the transport devices, which run at low speed, and delivered onto the supply belts which run at higher speed at right angles thereto, so that the wide flows of conveyed material from the removal belts are supplied onto the supply belts as narrow flows of conveyed material to the mould filling openings.

Title: Ink jet printer
Inventor: HORIKE MASANORI
IPC: B41J2/12
Filed: 1981-04-14
Abstract: In an ink jet printer, deflected ink droplets are moved precisely with respect to a predetermined point in that the deflection point of the ink droplets is determined a plurality of times and the deflection value is changed on the basis of the detected deflection point. The charge or deflection voltage level, which is changed for each adjustment of the deflection value, is a variable. If the setting of the deflection is repeated several times, the change value of the charge voltage level or deflection voltage level is reduced gradually in a predetermined ratio. The ink droplets are not charged continuously in accordance with the sequence of steps from the first to the last step but rather by means of a respectively predetermined group of steps, in which case other steps are missed out. In addition, the charging is carried out correspondingly in order to compensate a deflection of a charge voltage at an ink droplet, which deflection is due to charge voltages on ink droplets which have been charged and moved before the ink droplet.

Title: Remote-controlled compression tube
Inventor: MEIER HEINZ
IPC: A61B6/04
Filed: 1982-06-21
Abstract: The invention relates to a remote-controlled compression tube for an X-ray apparatus. The compression tube can be pivoted between the X-ray tube (5) and the patient-supporting plate (2) on a support arm (8, 41) from a waiting position into a working position in which it rests against the object being examined (39), and back again. In compression tubes the force acting on the operating lever should be proportional to the force exerted by the compression tube on the patient. In addition, the compression tube should be swivellable out of the beam path in such a way that it cannot collide with the components of the X-ray apparatus. For this purpose, the invention provides for the compression tube (9, 42) to execute a translatory movement extending its working range via the hydraulic cylinder (20, 58) allocated to it on adjustment of the operating lever (11, 68) and a pivoting movement bringing it into its working position, and for the regulating distance of the operating lever to be linearly proportional, at least in parts, to the regulating distance of the compression tube. A compression tube according to the invention is particularly suitable for use in X-ray apparatuses. <IMAGE>
