Patent DE-4212900-A1 (DE)
Inventor: FISCHER LUDWIG DIPL ING
IPC: B41J13/076
Filed: 1992-04-16
Abstract: The present invention relates to a feed device for media to be moved, especially recording media. The device preferably consists of a pair of pressure rollers (17, 20) which is pressed against a roller (2) by means of permanent magnets (10, 11). The magnetic circuit is completed by the ferromagnetic region (6a, 6b) of the roller (2). The pressure rollers are made of non-ferromagnetic material, especially plastic, and are at least partially within the magnets (10, 11) or supporting components (12, 13; 14, 15) conducting the magnetic flux. This has the advantage that the pressures exerted by the pair of pressure rollers (17, 20) can be increased without any change in the inertia behaviour. This feed device is therefore especially suitable for start/stop operation.

Patent DE-4232991-A1 (DE)
Inventor: DALHEIMER WALTER DIPL ING
IPC: A21B3/07
Filed: 1992-10-01
Abstract: Known insertion and extraction devices have, for the conveyor belt (2) (creeping belt), relatively large deflection radii on the belt tongues from both sides of a displacement table. Additional devices, such as, for example, wedge-shaped surfaces or transfer belts are necessary for handling small pastry articles or pieces of dough. The invention remedies this disadvantage, in that the belt tongues of the displacement table take the form of deflection cutters (11) on both sides, the conveyor belt (2) being in each case guided over the deflection cutter (11) only on the active belt tongue and being deflected on the belt tongue situated opposite via a pair of rollers (3) or (4). <IMAGE>

Title: Conversion of heat into mechanical energy - based on expansion and contraction-working fluid on heating and near-freezing
Inventor: SOELCH ROLAND
IPC: F01K25/02
Filed: 1992-11-16
Abstract: A process is claimed for converting heat into mechanical energy, for generating alternative energy or general energy requirements, esp. for utilising renewable heat sources, pref. by making use of natural temp. difference in the low-temp. range, using a liq. working medium that expands and contracts on alternate heating and cooling in a pressure-stable chamber. The process is characterised in that the working medium in one working cycle is cooled down to its m.pt. and its heat of fusion is withdrawn; the amt. of heat withdrawn is limited so that the working medium remains flowable and the flowability of the working medium is utilised to increase the heat exchange per unit area; and the expansion vol. on heating the working medium is used for mechanical work. ADVANTAGE - Preventing the working medium from solidifying increases the no. of cycles that can be completed in a given time (cf. DE 2814215).

Inventor: KLEINE HOMANN WALTER DR
IPC: C08G63/78
Filed: 1993-03-13
Abstract: The object is to prepare a high-molecular-weight polyester in such a way that it is possible to make even relatively small amounts of very high molecular weight available in an advantageous manner. This is achieved by preparing a polyester containing an alkenediol by continuing the polycondensation step to a viscosity number of 50 - 140 cm<3>/g and treating the resultant polyester with from 0.001 to 8 % by weight of a free-radical former which decomposes at temperatures in the range from 130 to 350 @C with a half value period of from 5 s to 120 min, and subsequently continuing the polymerisation to the requisite viscosity number. The process according to the invention allows high-molecular-weight polyesters having the desired property profile to be obtained.

Title: Circuit arrangement of an interface for switching system controllers interconnected via a parallel bus system
Inventor: MAIER KLAUS
IPC: H04L12/40
Filed: 1993-09-13
Abstract: The circuit arrangement of an interface for a parallel bus system which is designed as an integrated circuit is intended to be extended by means of an external connection of a simple memory with no special configuration in such a way that an increased information flow for specific applications is enabled. An additional memory controller, to which a random-access memory located outside the circuit arrangement is connected, is located within the bus interface. This memory can store a plurality of complete packets for both the transmit and receive directions and is connected via a bus manager upstream of the transmit buffer and downstream of the receive buffer. This memory is operated by the memory controller as a FIFO memory, a dedicated memory area whose capacity corresponds to the maximum possible packet size being provided for each packet to be stored. Only one additional memory controller needs to be provided within an interface designed as an integrated circuit for the operation of an additional memory. The memory controller is designed in such a way that a simple random access memory (RAM), which is operated as a FIFO memory, can be used.
