Title: EXCLUSIVE=OR gate with three main paths - each with two output transistors and one input transistor or diode
Inventor: MERKLE PAUL
IPC: H03K19/21
Filed: 1980-11-12
Abstract: The exclusive-OR gate has three parallel lines connected to a main line at the input end of the gate. Each parallel line has a bipolar transistor or a FET connected into it. Each transistor is controlled by one of the gate's three inputs. Three parallel output lines are connected to the output end of the parallel lines. Each output line has two series bipolar transistors or two series FETs. In a second configuration, the three parallel lines with their three transistors are replaced by a single transistor or FET and three diodes. Each diode is connected directly to an input. The six output transistors remain. Two further circuits are described, each having two inputs instead of three. The numbers of transistors and diodes are correspondingly reduced.

Patent DE-3102832-A1 (DE)
Title: Sealing arrangement for panel-shaped closing elements
Inventor: NEHL FRED ING GRAD
IPC: E06B7/23
Filed: 1981-01-29
Abstract: The invention relates to a sealing arrangement for panel-shaped closing elements, especially hatch covers, with flexible hollow profiles as sealing elements which are closed off relative to the outside and which are provided with inlet valves. The sealing arrangement is, at the same time, provided with a valve arrangement, by means of which the gas pressure inside the hollow profile can be lowered below atmospheric pressure and maintained at the set underpressure. The hollow profile is designed so that, under an internal pressure corresponding to atmospheric pressure, it exerts the desired sealing pressure. When a vacuum is applied, the hollow profile collapses and thus comes out of contact with the associated sealing face. During operation, the sealing pressure is exerted by means of the inherent tension of the hollow profile. A leak of the hollow profiles or of the valve arrangement consequently does not impair the sealing effect. <IMAGE>

Title: Method for rolling strip metal
Inventor: YAMAMOTO HIROYASU
IPC: B21B1/22
Filed: 1981-06-16
Abstract: In this rolling method, three or more work rolls are arranged with their centres essentially on a common straight line, so that the adjacent pairs of work rolls (11, 12; 12, 13; 13, 14) form a rolling pass (P1, P2 and P3 respectively) between them. The work rolls are driven in such a way that the rolls closer to the exit end of the roll stand rotate with an increasing peripheral velocity. The metal strip is fed continuously through each pass and passed around part of the circumference of the work rolls (12, 13) arranged between the work rolls (11, 14) at the two ends of the roll stand. The strip is thus rolled between each pair of adjacent work rolls. The work rolls are driven in such a way that the peripheral velocity of the work roll revolving at higher speed is greater at least in one of the work roll pairs than the velocity at which the strip leaves the roll pass formed by this work roll pair. <IMAGE>

Patent DE-3145391-A1 (DE)
Title: Compressed-gas switch
Inventor: ZUECKLER KARL DR RER NAT
IPC: H01H33/915
Filed: 1981-11-12
Abstract: In a compressed-gas switch having two stationary nozzle-shaped switch contacts (1, 2), the latter are shunted out in the switched-on position by means of a hollow-cylindrical, moving switch contact (4). A blowing device consisting of a piston and moving cylinder (5) is provided in order to blow out the arc. The cylinder (5) is coupled to the moving switch contact (4) and, during the switching-off process, moves away from one of the stationary switch contacts (2). Furthermore, by way of a precondition, an insulating material body is provided which reduces the incident flow cross-section between the stationary switch contacts (1, 2) during the switching-off process. In order to increase the size of the separating path (T) between the two stationary nozzle-shaped switch contacts (1, 2), and in order to increase the magnitude of the rated voltages while simultaneously increasing the radial incident flow speed, according to the invention, the insulating material body is formed from a plurality of radially directed laminates (9) which are connected via ducts (10) that are parallel to the axis to the compression space (6) of the blowing device, and are arranged in the blowing region, located between the shunting-out switch contact (4) and the cylinder base (7), in such a manner that they bound at least one radial flow guide (11). <IMAGE>
Patent DE-3146638-A1 (DE)
Title: Boiling point control device for cooking stoves to save energy
Inventor: KARR DIETER
IPC: F24C15/10
Filed: 1981-11-25
Abstract: Today's cooking stoves have temperature-controlled hotplates. However, since the boiling process is a phase transition which depends on external parameters, such as air pressure or salt content of the product, the control of the simmering process is difficult. A method has been developed which registers the phase transition itself. During boiling, bubbles of steam are formed which cause the liquid, saucepan and hotplate to vibrate. The size of the vibration amplitudes is measured and the signal is used to control the heat supply. The method avoids both boiling over and initiation of the boiling process.
Patent DE-3200619-A1 (DE)
Title: Feed rack
Inventor: MAUERER ERNST
IPC: A01K1/06
Filed: 1982-01-12
Abstract: A feed rack is provided, having a rack frame (3) which can be pivoted about the axis of an upper supporting rod (4) between a lock-out position, in which the feed rack impedes the access of the animals to the manger (15), and a storage position in which a lower support pipe (5) projects somewhat above the rear edge (15b), from the animals' standpoint, and the manger (15). In the latter position the rack can support a layer of feed for slow consumption which can be taken up by the animals. In the first mentioned position, self-catching apertures (16) can be selectively opened in order to allow the head of the animals to pass through the plane of the rack, after which the self-catching aperture (16) can be converted, by a lateral inward pivoting movement of the catcher rods (17) limiting the latter, into a catching position for the animals, so that the latter can, for example, be milked. In order to bring about the pivoting movement, a pivot axis (11) is mounted in the supporting pipe (5) and can be rotated via a pivot handle (12 or 12a), and pivot levers (8) are attached in the region of breaks in the support pipe (5) which hold the pivot axis (11) and hence the lower support pipe (5) in the respective pivot position. To bring about the opening and closing movement of the catcher rods (17), a shift linkage (21) is arranged in the region of the upper supporting rod (4), the members of which lie on the side of the feed rack remote from the animals. A particular effect of the design of the feed rack is that the leading chains of the animals cannot be caught up, and in addition a fault-free, strong construction is obtained. <IMAGE>
Patent DE-3210110-A1 (DE)
Title: Diaphragm pump
Inventor: BECKER ERICH
IPC: F04B11/00
Filed: 1982-03-19
Abstract: A diaphragm pump is provided with a fluidically acting flow rate control. The inlet connection (12) is connected to an inlet valve (6) and at the same time to a damping chamber (10). Its volume is preferably limited by way of a damping diaphragm (13) and variable so that pulsating impact pressures of the inflowing feed liquid are damped in the intake area. According to the range in which the damping chamber is operative, smaller or larger quantities of intake volume (V1, V2) flow to the compression chamber (4) of the diaphragm pump. Accordingly the flow rate of the pump can be increased or reduced by varying the volume of the damping chamber (10). The controllability is at the same time achieved in a very simple manner not susceptible to faults by means of a rotatable adjusting knob. <IMAGE>

Patent DE-3228085-A1 (DE)
Title: Robot
Inventor: HELLMANN WOLF-DIETER ING GRAD
IPC: B22D17/20
Filed: 1982-07-28
Abstract: The invention relates to a robot for removing and depositing workpieces from production machines, especially from an injection moulding machine, with a support which is preferably movable in the direction of at least two linear axes and on which a guide arm carrying a gripper is mounted so as to travel in a straight line and preferably in a third linear axis, and with a drive device for intermittent to and fro motion of the guide arm. Known robots of this kind are unsuitable because of the large space which they occupy, their heavy construction and also the complicated control of the movement of the gripper. A robot which takes up little space and is easy to control was therefore required. This object is achieved when a strip-shaped element is arranged on the guide arm, is drivable relative to the latter in order to perform a movement, and carries the gripper, and where a brake device for the strip-shaped element is provided which is stationary relative to the guide arm. The drive device for the guide arm and also the gripper is substantially simplified in this manner. The robot takes up less space, and the control of the gripper movement is considerably simplified.

Title: Method and apparatus for milling or grinding internal and external threads of relatively large diameter
Inventor: ZIMMERMANN EBERHARD
IPC: B23G3/08
Filed: 1982-10-04
Abstract: In a method of producing internal and external threads of relatively large diameter by means of a milling or grinding head, provision is made for the meshing of a thread, axially connected to the milling or grinding head, with a threaded extension of an axially fixed support device producing the circular movement to be used for driving the milling head in the direction perpendicular to the plane of the circular path, in the course of which the relative rotation between thread and threaded extension, derived from the circular movement of the milling head, takes place about the fixed axis of the thread to be produced. Serving to carry out this method is an apparatus which comprises a milling or grinding head (3) which can be guided in a circle relative to a workpiece (1) by means of a support device (14) and which is distinguished by a guide arbor (21) which can be secured in a fixed position in the thread axis (15) corresponding to the centre point of the guide circle, by a guide device for transmitting angle changes between milling head (3) and guide arbor (21), and by a thread on the support device (14), which thread meshes with a corresponding threaded extension (16) on the milling head (3) in such a way that they can be rotated relative to one another and with the height of the milling head (3) being adjusted, the milling head (3) being axially fixed and radially rotatable relative to the threaded extension (16). In this way, it is possible, in a cost-effective manner, to quickly and ... threads even of very large diameter in large and difficult-to-manipulate workpieces. Original abstract incomplete. <IMAGE>
