Title: Stacked rectangular containers with radial flange - are separated by means of rotary wedge cam segments
Inventor: AMMANN SIEGFRIED
IPC: B65G59/10
Filed: 1976-09-11
Abstract: A stack of rectangular plastic container is placed in a support frame (54), in order to unstack the containers (30) by removing the lowest one from the stack. The top edges of the tapered container walls are provided with a flange which is used to prise the stacked containers apart. A vertical shaft (3, 6) at each corner is provided with radial segment (27, 28) with which the container flanges are engaged. The shaft segments have axial cam profiles which when the four shafts are rotated through about 90 deg., force the gap between the lowest and the following container flange apart. Thus the lowest container is separated from the stack which allows the stack to be lowered in order to repeat the operation.

Title: Control signal generating and maintaining circuit - maintains defined voltage across thyristor output after switching, with Zener diode reference
Inventor: ELLSIEPEN HANS-DIETER DIPL ING
IPC: H03K3/037
Filed: 1976-09-25
Abstract: The device generates and maintains a defined control signal across output of logical connections at and after transition form first to second operating voltage. During normal operation the logical connections emit a signal equivalent to the control signal, especially for application during transition from the working voltage to the steady potential in a static semiconductor memory. The thyristor is controlled on the cathode side. On the anode side, the thyristor is connected to the operating voltage present at the time and on the cathode side to the voltage representing the control signal. The Zener diode (3') of the monitor (3) detects a drop in the working voltage (VA).

Title: Linear translatory stepping motor - includes clamped springs with free end carrying friction pad and is set perpendicular to motion to improve feed accuracy
Inventor: RECKLIES SIEGFRIED DR ING
IPC: H02K7/065
Filed: 1977-04-16
Abstract: The linear stepping motor controls the positioning of slides in numerically controlled machine tools, and offers a high precision feed using parts made without rigorous demands on their accuracy. This is achieved with springs (2) which are clamped at one end in the recesses (3) of the housing (1) and carry a friction pad (7) at their free end. The excitation of solenoids 4/5 or the application of other forcing drives, such as magnetostrictive units, fluidics etc. causes a shift of the springs acting as a parallelogram with the pad (7) thrust against the guide track (8). Incremental feeds of less than 1 um can be attained, and the adherence against the track can be enhanced with magnets.
Patent DE-2734158-A1 (DE)
Title: Protector device for ultrasonic testing manipulator for reactor vessel - has impact detector mounted on flexible bar and actuating limit switches
Inventor: KLEEMANN ROBERT
IPC: G01N29/265
Filed: 1977-07-28
Abstract: A protective device for preventing a testing manipulator from striking other objects is intended particularly for ultrasonic manipulators used in testing reactor pressure vessel walls, duct connections, penetrations etc. in depth through the metal. The protective device comprises a limit switch mounted on the manipulator and an impact detector firmly mounted on one end of a flexible bar, the other end of the bar being firmly fixed to the manipulator. When the impact detector is deflected, the flexible bar is either bent or twisted. The bar pref. has a circular cross-section. The limit switch is conventionally constructed as a distance switch, a switching tongue associated with it being attached to the impact detector, so as to close the switch when the impact detector is moved on impact. The appts. for supporting the impact detector relative to the manipulator is a simple bar fixed at both ends. By comparison with previous equipment of this type, therefore, complicated and expensive seals, corrugated belows and the like are eliminated. Nevertheless, the bar always operates within its elastic range and therefore always restores the impact detector to its central neutral position after an impact, regardless of the direction or type of deflection which it has undergone.
Patent DE-2739182-A1 (DE)
Title: Four layer SCR system - has outer layer used as emitter, with primarily ignited zone, and current flow compensating interference currents
Inventor: SILBER DIETER DR ING
IPC: H01L31/111
Filed: 1977-08-31
Abstract: The rectifier has at least four layers of different conductivities. One outer layer is designed as an electron or hole emitter, and has a primary zone ignited by a control power, a part of the rest of this emitter layer. A current derived from one of the rectifier junctions is fed into the primarily ignited zone (51) of the emitter layer (2) in case of presence of du/dt interference currents and forward blocking currents. This current generates a compensation potential by its lateral flow into the remaining part (52) of the emitter layer. This potential is generated across the sheet resistance of the primarily ignited zone (51) or of the junction with the remaining zone (52).

Title: Stabilised self-steering gear for boat - has intermediate damping element to prevent over-reaction in servo-linkage
Inventor: VOLZ EDMUND DIPL ING
IPC: B63H25/04
Filed: 1977-10-15
Abstract: The self steering gear for a sailing boat has a wind vane (2) and a rudder blade (1) both pivoted about horizontal axes and linked by a servo drive. The boat steers with the wind, with the servo drive providing the steering force. A damping element (3) is included in the linkage to provide a steadier steering control. The damping element ensures that the boat does not oscillate about the set course and thus sails more efficiently.

IPC: A01G9/12
Filed: 1977-12-28
Abstract: In order to support a tree in a roof garden, use is made of a bell-shaped cage with an upper opening (1). The cage has horizontal struts (2) and outer-casing struts (5) which are bent in the form of a bell or arranged in the manner of a pyramid. After introducing the tree roots into the cage through the upper opening (1) of the latter and placing said cage on its standing surface (4), the cage and tree roots are filled with, and surrounded by, earth. The tree is thus supported against strong winds by a dimensionally stable three-dimensional structure (2, 5, 4) being stably attached, by means of the earth, to the roots of the tree. <IMAGE>
