Patent DE-3903605-C1 (DE)
Title: Method and heat engine for converting thermal energy into mechanical work
IPC: F02G1/04
Filed: 1989-02-08
Granted: 1990-07-12
Abstract: Method for converting thermal energy into mechanical work with the aid of thermodynamic p/V cyclic processes. Two cyclic processes are coupled - a first cyclic process having a first curve at constant volume, a second curve relating to expanding volume and a third curve, which closes the cyclic process and relates to decreasing volume, and a second cyclic process, which correspondingly has three curves. In the first cyclic processes, the changes in state of the first curve are undertaken in isochoric fashion by the supply of thermal energy, the changes in state of the second curve are undertaken isothermally by the supply of thermal energy, and the changes in state of the third curve are undertaken isobarically in conjunction with the dissipation of thermal energy. The thermal energy supplied to the two cyclic processes for the isothermal change in state is converted into the mechanical work. <IMAGE>

Title: Fluid friction clutch with centrifugal weights for gap adjustment
IPC: F16D35/00
Filed: 1989-02-24
Granted: 1989-12-07
Abstract: The invention relates to a fluid friction clutch 1, in the case of which the inner discs 12a, 12b, assigned to the driven clutch part, the hub 4, are designed as adjusting discs. If a given absolute rotational speed imparted to the hub 4 by the housing 2 as driving part is exceeded, the centrifugal weights 19 move radially outwards counter to the force of an annular spring 24 urging them inwards, and permit the outer edges 37 of the inner discs 12a, 12b, designed as conical plate springs, to move axially away from the outer discs 11 and enlarge the gap with respect to the latter. As a result of this, the transmittable torque between the outer discs 11 and the inner discs 12a, 12b is limited. The torque can thus be appropriately designed, in the case of high absolute rotational speeds, in accordance with the construction of the oblique faces, to control the proximity of the two outer edges to one another. <IMAGE>

Title: Bottle reverser or inverter - uses gripping head opened and closed by first cam and swivelled by second cam
IPC: B08B9/42
Filed: 1990-07-14
Granted: 1991-08-08
Abstract: The bottle reverser uses a swivel gripper which is mounted on a rotor and which is opened/closed by a first cam in certain parts of its path. It is swivelled by a second cam in other parts of its path. The second and fourth cam should form a cam piece (5) and are thus probed by the same feeler (4). Gearing (6) between the feeler (4) and gripper (3) converts a first part (I) of the feeler stroke into an opening or closing movement and a second part (II) into the swivel movement. USE/ADVANTAGE - Bottling plants etc. Single feeler and cam system actuates all gripper movements in simple reliable layout.

Title: Continuous glass-making charge drying and preheating process
IPC: C03B3/02
Filed: 1990-12-12
Granted: 1992-07-09
Abstract: In a process for continuously drying and preheating the cullet and/or batch charge material of a glass melting furnace using the furnace off-gas, the charge is in the form of a vertical, gradually descending column with an increasing temp. in the downward direction, the steam generated during drying is immediately drawn off with the used off-gas stream without condensn., at least part of the off-gas is passed directly through a first region of the charge column and the part of the off-gas used for direct heat transfer to the charge is passed transversely through the column. The novelty is that the velocity of the off-gas stream, passing transversely through the charge column, is reduced at the outlet side. Also claimed is an appts. for carrying out the above process.

Patent DE-4230376-C1 (DE)
IPC: F02M61/16
Filed: 1992-09-11
Granted: 1993-04-22
Abstract: In known electromagnetically controllable valves the valve needle consists of a tubular armature section, a tubular valve sleeve section and a valve closing member section. The armature section is linked to the first end of the valve sleeve section by means of a first solder and the valve closing member section is linked to the other end of the valve sleeve section by means of a second solder. This production process is relatively expensive and costly because of the two soldering operations required. In a new valve needle (58), a tubular actuating part (31) consisting of an armature section (36) and of a valve sleeve section (38) is produced by injection moulding followed by sintering, according to the metal injection moulding process. The actuating part (32) is then linked to a valve closing member section (46) by means of a solder, so that the valve needle (58) can thus be produced in a simple and economical manner. This valve needle is particularly suitable for injection valves in fuel injection systems of internal combustion engines.

Granted: 1994-09-01
Abstract: A floating calliper disc brake for motor vehicles has a brake anchor plate which is integrated in the axle knuckle of the vehicle to support the circumferential forces and to guide the brake linings (6, 7). In order to keep the final assembly on the vehicle as simple as possible and to facilitate automatic assembly, the floating calliper (3) is supplied with brake linings (6, 7) attached thereto as a preassembled unit. The brake linings (6, 7) are releasably attached to the floating calliper (3) by means of leaf springs (10) attached to their rear plates (8). According to the invention, the leaf spring (10) of the outer brake lining (7) serves additionally to prestress the floating calliper (3) radially in relation to the arms (1, 2) of the brake anchor plate. As a result, another spring provided for this purpose can be dispensed with. The assembly of the floating calliper (3) on the vehicle is simplified because this additional spring does not have to be assembled. <IMAGE>

Abstract: FIELD: mechanical engineering. SUBSTANCE: flexible coupling has two coupling halves constructed as two concentrically mounted sleeves 1 and 2 with longitudinal ports 3 made in their walls and flexible links 4 made up as pieces of a rope. The ends of links 4 pass through ports 3 and are secured on outer sleeve 2. The middle parts of links 4 enclose spring ring 5 positioned freely. When a torque is applied to inner sleeve 1, the sides walls of longitudinal ports 3 affect links 4 which, in turn, set outer sleeve 2 in rotation. Simultaneously, the middle parts of links 4 involve spring ring 5 in rotation, the ring being deformed depending on branch tensions. The radial displacements of the shaft in the coupling are compensated owing to deforming of spring ring 5 and possibility for middle parts of the flexible link branches to move over the spring ring.
