Patent DE-3909318-A1 (DE)
Inventor: HOBELSBERGER JOSEF
IPC: A23G9/08
Filed: 1989-03-21
Abstract: In a process for making an ice body (10) from clear ice, with an inclusion (8), adequately cooled cooling bodies are placed in contact with a liquid to be solidified, e.g., water or drinkable liquids containing water. This can be done, for example, by immersing the cooling body in water. An ice body forms around the cooling body. When detached from the cooling body, it has a cavity on the base of which an inclusion (8) is arranged. The cavity if filled, e.g. with water, and cooled, which results in the formation of an ice body (10) with an inclusion (8). The process of the invention requires no additional supporting elements. In addition, these clear ice bodies can be thawed, joined together and refrozen to form complicated shapes in the form of animals or utility articles.

Title: Apparatus for manipulating pallets
Inventor: RAFF KARL
IPC: B23Q7/14
Filed: 1989-04-03
Abstract: An apparatus for manipulating stackable pallets and pallet stacks, in particular workpiece pallets, is described. Provided vertically one above the other in a machine frame (6) are a stack receptacle (8) for receiving and holding at least one pallet (P), a delivery station (9), and a transfer means (16) for passing pallets from the stack receptacle to the delivery station and back again. Arranged below the delivery station is a preparation station (7) in which a further pallet stack (S2) is kept ready. With a lifting frame (16) provided as transfer means, pallet stacks are transferred from the preparation station (7) into the stack receptacle (8), and individual pallets (PS) are transferred from the underside of the stack (S3) in the stack receptacle (8) into the delivery station (9), from where they are discharged for further machining. The mode of operation can also proceed the other way around. <IMAGE>

Title: Transferring rounded dough portions - by gripper jaws suspended from housing contg. programmed electromagnet controls
Inventor: KOEVY SANDOR
IPC: A21C9/08
Filed: 1989-04-11
Abstract: Rounded portions of dough are transferred from an initial arrangement, e.g. in concentric rings, into a further arrangement such as parallel rows of depressions holding the portion during raising. The portions are for making rolls. Each piece is transferred while engaged by gripping jaws (327) pivotable about pins (325) below a housing (32) contg. lifting magnets subject to a programmed controller, the housing itself being suspended. Inward and outward pivotal movements of the jaws are dependent on rollers (328) coupled to their inner faces and forced inwards and outwards by the changing gaps imposed by the surface of a tapered slider (324) mounted near the end of an axial shaft (323). Affixed to the end of the sahft is a concave ejector plate (326) which like the dough-contacting surfaces of the jaws is coated with felt. Above the rollers (328) the jaws are embraced by a peripheral spring (329). ADVANTAGE - Dough portions are effectively transferred without sticking to the transfer mechanism.

Title: Process and apparatus for feeding textile sheet-like structures to a machining apparatus
Inventor: WOLF JUERGEN
IPC: A41H43/02
Filed: 1989-05-09
Abstract: The invention relates to a process and to an apparatus for feeding textile sheet-like structures, in particular adhesive-bonding units, to a machining apparatus, in particular to an adhesive-bonding apparatus, in the case of which blanks which are initially arranged in stacks are separated and laid one upon the other to form adhesive-bonding units, and the latter are then conveyed to the machining apparatus. The object of the invention is to develop a process and an apparatus by means of which the possible capacity of the adhesive-bonding apparatus can be fully utilised. The object is achieved according to the invention in that the adhesive-bonding units are arranged on a preliminary conveyor, in that the adhesive-bonding units are then delivered from the preliminary conveyor onto an intermediate conveyor, which in this arrangement is operated approximately at the same conveying rate as the preliminary conveyor, and in that the adhesive-bonding units are then conveyed from the intermediate conveyor onto an adhesive-bonding conveyor of the adhesive-bonding apparatus, the intermediate conveyor being operated at approximately the same conveying rate as the adhesive-bonding conveyor. Another solution is distinguished in that the separation and laying of the blanks one upon the other to form adhesive-bonding units is carried out manually, preferably by two members of operating staff who share the work between them.

Inventor: SCHEFFEL MARTIN
IPC: F15B11/02
Filed: 1991-05-14
Abstract: A proportional pressure-regulating valve for an actuator (16) has a main valve (11) having a valve spool (20) which is axially displaceable from a neutral mid-position, blocking a valve port (21) connected to the actuator (16), to either side into a further position in which the valve port (21) is connected to a supply port (22) or an exhaust port (23). When the valve spool (20) is uncontrolled, it is moved by a return spring (33) into a fourth, end position in which the port (21) is isolated from both valve ports (22, 23). The valve spool (20) is rigidly connected to a damping piston (36), which de-limits a damping chamber (35). The damping chamber (35) is connected to a pilot valve (12) providing the valve spool (20) with control pressure medium. Under normal operating conditions, a minimum pressure in the damping chamber (35) prevents the damping piston (36) from entering the chamber and so deters movement of the valve spool (20) to its fourth, end position. <IMAGE>
