Patent DE-3906423-A1 (DE)
Title: Flexible transport and assembly apparatus for pallets in machine tools
Inventor: BLUEMLE RUDI
IPC: B23Q7/14
Filed: 1989-03-01
Abstract: In a flexible transport and assembly apparatus for pallets, loaded with workpieces to be machined, in machine tools with in each case different work-table heights, it is proposed in order to compensate for these table heights to allocate stationary pallet buffer tables with three or more pallet places to each machine tool and to connect the pallet buffer tables via transfer bridges to the machine work table, all pallet-carrying and pallet-transfer elements being equipped with supporting elements, permitting rolling friction, for the pallets so that the transport of pallets placed on the pallet buffer table to the machine-tool work table is possible by manual intervention. The elements permitting rolling friction, considered by themselves, are known ball rolling elements in individual or rod form.

Title: Circuit arrangement for memory devices to store data with validity flags
Inventor: HARDERS RAINER DIPL ING
IPC: G11C7/10
Filed: 1989-03-21
Abstract: In a memory device which is constructed in two parts, consisting of a first memory (ATM) with random access and a second, content-addressed memory (CAM), two groups of validity flags are used for entries in the first memory (ATM), and one validity flag (V) is used for entries in the second memory (CAM). If all entries in the memory devices are to be declared invalid, all validity flags (V) in the second memory (CAM) are changed simultaneously, whereas in the first memory (ATM) control switches to the inactive, deleted group of validity flags, and the validity flags in the blocked group are successively changed. Further deletion requests which arrive during such a deletion process cause the first memory (ATM) to be temporarily blocked until the deletion process is complete. During this time, memory operation is carried out and supported by the second memory only. <IMAGE>

Patent DE-3915418-A1 (DE)
Title: Mixer arrangements
Inventor: TRAENKLE GUENTHER DIPL PHYS
IPC: H03F3/68
Filed: 1989-05-11
Abstract: A mixer arrangement is described for converting an input signal having a plurality of superimposed (heterodyne) signals, preferably for quadrature conversion, in which operating currents modulated by the input signal flow through a plurality of mixers which are controlled by various superimposed signals. An output current modulated by the input signal is generated in a common voltage-current converter and is divided into a plurality of partial currents in a divider stage, which partial currents form the operating currents of the plurality of mixers. A high closed-circuit current is thereby provided in the input stage of the voltage-current converter, by means of which improvement in the linearity characteristics of the input stage is achieved. In the case of predetermined linearity requirements, a substantial improvement in the power demand can be achieved in comparison with mixer arrangements having a plurality of voltage-current converters.

Patent DE-3916603-A1 (DE)
Inventor: BIRKICHT HORST
IPC: B65D19/12
Filed: 1989-05-22
Abstract: In a pallet, which is particularly suitable for transporting and/or storing vehicle tyres, having a bottom part (2) and two side parts (4, 6) which are located opposite one another and can be attached to the bottom part (2) in particular vertically, at least one pair of rod-type parallel bearing elements (8) for the vehicle tyres is arranged between the side parts (4, 6). The bearing elements (8) have a predeterminable spacing from the bottom part and a smaller spacing from one another than the outside diameter of the vehicle tyres to be accommodated. With the aid of a pallet of this type, the deformation of the lowest layers of tyres due to the weight of layers of tyres lying above it is prevented and a great packing density is achieved inside the pallet. <IMAGE>

Title: Device and method for determining the thermal conductivity and concentration of liquid mixtures
Inventor: KOBAYASHI HIROSHI
IPC: G01N33/22
Filed: 1989-06-01
Abstract: The device for ascertaining the thermal conductivity and/or a concentration of a mixture (11) consisting of first and second liquid components having different thermal conductivities has a thin-film resistor (23) which is arranged within the mixture (11). This thin-film resistor (23) has a temperature-dependent resistance. In order to increase the resistance, the thin-film resistor (23) is supplied with a current which is in turn limited after a fixed time in order to lower the resistance. The rate of change of the resistance is measured. This measured rate of change corresponds to the thermal conductivity of the mixture (11) and therefore also to the concentration of the first liquid component. The rate of change is converted into a value which shows the thermal conductivity and/or the concentration of the first liquid component of the mixture (11). <IMAGE>

Title: Overflow protection for dishwashing machine with float switch - ensures that water supply is turned off by build=up of water in trough below skirt
Inventor: SCHWARZWELLER PETER
IPC: A47L15/42
Filed: 1989-09-13
Abstract: The outer casing (10) surrounds the skirt (11) of the inner container (12) which is spot-welded (15) to the sidewalls (12a, 12b) to form a trough (16) for overflow during operation.

Patent DE-4014405-A1 (DE)
Inventor: SCHULZE ECKEHART
IPC: G05B19/42
Filed: 1990-05-04
Abstract: A process is disclosed for controlling the revolutions of the impression cylinder (29) of a printing machine (10). The coordinate driving units (52, 53), which are designed as valve controlled (49, 51) hydrocylinders (42, 47), are operated according to a play-back process according to which the coordinate driving units (52, 53) are operated according to a follow-up process in which position set values are electrically preregulated and mechanical real values are fed back. The slowing down path  DELTA S (contouring error) is continuously measured at least during the last revolution of the pressure roller (29), so that when a threshold value  DELTA Smax is exceeded, the tracking speed VB is reduced or a transition to an intermediate revolution curve occurs. A printing machine for carrying out the process is also disclosed.
Patent DE-4015084-A1 (DE)
Inventor: HEILIGER ROBERT WILHELM
IPC: E21D15/44
Filed: 1990-05-11
Abstract: The invention relates to a process for the economic manufacture of a piston-cylinder unit in which at least the cylindrical surfaces, against which a sealing ring is applied, are coated after rough premachining with an adequate thickness of e.g. a powdered lacquer preferably based on epoxy resin and a cross-linking agent and adequately heated to cross-link the lacquer.

Title: Shut=off system for valve for thermoplastic melts - prevents mechanical locking of tapered plug and gives better sealing against polymer leakage under plug sealing faces is achieved
Inventor: CALLHOFF ERNST
IPC: B29C48/50
Filed: 1990-06-06
Abstract: A shut off device for a valve with a conical bore and used for plastics melts is described in which locking of the tapered valve plug in a matching tapered bore during heating is avoided. The valve has a housing with a conical bore in which a rotatable conical plug is located. To prevent locking of the plug during heating of the valve body the plug is gently raised and lowered by a thermally expanding bolt which can be heated or cooled. The rod is fixed in the housing and lifts the plug along the long axis against the force of a spring. The arrangement prevents fluid or polymemelt penetrating under the sealing surfaces on the valve plug circumference which renders the valve ineffective. USE/ADVANTAGE - For sealing off polymer flow in a polymer filtering device. Prevents mechanical locking of the tapered plug and also stops polymer leakage under the plug edges. Expensive valve cleaning is avoided.

The wefts of the second system are pref. thinner than those in the third system, and the wefts of the third system are stiffer than those in those in the second system and are more resistant to wear. ADVANTAGE - Gives improved resistance to wear, without affecting working characteristics of the woven material.
