Title: Hydraulic control device
Inventor: ALTMANN UWE ING GRAD
IPC: F15B11/17
Filed: 1983-06-09
Abstract: A hydraulic control device (10) is proposed which, from the delivery flows of two fixed-displacement pumps (11, 12), can control a continuously variable volumetric flow, independent of load pressure, to a common consumer (15). Allocated to each pump (11, 12) is a 3-way pressure balance (16, 17), the spools (21, 22) of which lie coaxially and one behind the other in a longitudinal bore (19) and are held by springs (47, 49) preloaded to different degrees in initial positions in which they are at a distance from one another. A first spool (21), as a function of the pressure gradient of an adjustable restrictor (14), can be deflected into regulating positions in which it bears at the end face against the second spool (22) so that the coupled spools (21, 22) perform the volumetric-flow control actions. With the control device (10) of compact and simple construction, an energy-saving mode of operation is possible by one fixed-displacement pump being able to be switched off when required. <IMAGE>

Title: Metal/plastics component, metal part and plastics part being connected together by means of jointing
Inventor: KAEUFER HELMUT PROF DR
IPC: E04C3/29
Filed: 1983-10-05
Abstract: Metal/plastics component, metal part and plastics part being connected together by means of jointing. The invention relates to a plastics/steel composite supporting element. It consists of a plastics profile which is adhesively bonded to two metal profiles. The adhesive bonding at the edges takes place as combined form-fit/adhesive connection, that is to say the adhesive connection due to the adhesion between the joint parts is aided by an additional form-fit. One field of application is in the replacement of steel girders by such plastics/steel composite structures for the medium loading range. The plastic's good oscillation damping characteristics, high corrosion resistance and ability to insulate electrical voltages can be utilised here. Other advantages are the low weight, the low costs and the possibility of attaching multi-functional elements to the plastics part directly during production.

Title: Apparatus for collecting and separating rolled material in bar form
Inventor: SCHMITZ ALFRED DR ING
IPC: B21B39/00
Filed: 1983-10-21
Abstract: The invention relates to an apparatus for collecting and separating rolled material in bar form. Apparatuses of this kind are generally provided following cross conveyors or the like and have receiving arms which interact with pockets of a magazine. A plurality of bars received by the receiving arms are in each case lowered into the pocket-type magazine together, resulting in interruptions to operations. In addition, the distance which the roll bars fall is generally so considerable that a very high noise level is associated with this operation. Finally, apparatuses of this kind are suitable to only a limited extent for separation. The invention leads to a particularly quiet embodiment with a reliable construction since the receiving arms are designed as forks which can be swivelled about an axis extending very close underneath the front zone of the cross conveyor. The inner contour of the forks is approximately crescent-shaped and, to form the swivel bearing, is provided at one end with a circular arc concentric to the axis. In particular, the inner contour follows a certain angular segment of a hyperbolic spiral, with the result that, during the process of lowering, a gradually increasing filling cross-section is obtained which fills with the rolled material while maintaining a constant minimum distance of fall. In the reverse direction, this device is suitable for separation. Since only very small changes in height are performed in each case, the ... Original abstract incomplete.
Patent DE-3344499-A1 (DE)
Title: Slinging device for lifting appliances
IPC: B66C1/10
Filed: 1983-12-09
Abstract: By the slinging device according to the invention, loads with very irregularly distributed weight can be lifted or lowered exactly in their centre of gravity in order to avoid a slanted position. It is intended above all for the demoulding of precast concrete members which have not yet set. The often very different and irregular moulds must always be lifted absolutely vertically in order to avoid damage to the unfinished concrete parts. The automatically vertical lifting or lowering of the loads is achieved by preferably two elements arranged at right angles to one another, e.g. pendulums, being attached to the slinging device, which elements, via operating members and adjusting mechanisms, adjust the fastening point of the crane at the slinging device on the one hand and, perpendicularly thereto, the fastening points of the load at the slinging device on the other hand only in the slanted position of the slinging device until the pendulums are no longer connected to the operating members, i.e. the slinging device is completely horizontal and the load can be lifted or lowered exactly vertically in its centre of gravity. <IMAGE>

Title: Method for recovering energy from a heat storage medium which is able to form a crystalline solid in the form of a stoichiometric hydrate, energy storage device which uses said method, and heating system, cooling system and energy transformation system provided therewith
Inventor: LAUMEN MICHAEL
IPC: F25B1/08
Filed: 1983-12-13
Abstract: The method according to the invention, for the purpose of storing and recovering heat, utilises two phase changes of a salt hydrate, for the purpose of heat storage a salt of the higher hydration level first being fused and then dehydrated, while in the heat recovery process the heat of solution is recovered by adding water and the heat of fusion is recovered upon renewed crystallisation. This makes it possible to achieve storage densities of about 450 kWh/m<3> when NaOH is used in the temperature range of 65 DEG C, the storage material only requiring costs of less than 2 German Marks per kWh of storage capacity. In other temperature ranges it is possible to achieve energy densities of more than 500 kWh/m<3>. In particular, the heat storage medium both in the charged and in the discharged stage is a crystalline solid and can be stored for any length of time at room temperature. As a result, it is also possible to construct, for example, seasonal storage devices in the field of the heating of buildings. The design of an energy storage device is demonstrated which operates by using the method according to the invention, and proposals are made for the incorporation of such an energy storage device into a solar heating system, cooling systems and heat transforming systems. <IMAGE>

Patent DE-3421779-A1 (DE)
Title: Port-controlled two-stroke engine
Inventor: DOLZER WALTER
IPC: F02B75/02
Filed: 1984-06-12
Abstract: In a port-controlled two-stroke engine with crankcase pump, an overflow valve (6) is provided in the piston head (10) for scavenging. The overflow valve is formed by a leaf valve, the swivel axis of the leaf (8) being arranged between the overflow valve orifice (7) and the exhaust port (4). In order to raise the overflow valve contact pressure produced by reversal of the direction of movement of the piston (3), the leaf (8) is provided with a counterweight (9). In this way, automatic control of the overflow valve (6), that is, control determined solely by the excess pressure in the crankcase, (2) is ensured, with efficient scavenging. <IMAGE>
Patent DE-3421835-A1 (DE)
Title: Torque converter
Inventor: WOBST JOSEF
IPC: F16H3/74
Filed: 1984-06-13
Abstract: In both embodiments, torque conversion is achieved by the fact that the lever arms e, which are under constant driving pressure and are capable of anything from standstill to rotation about the drive shaft a, can in interaction with the driving gear wheels c in output wheels d, necessarily achieve - in oscillating fashion in the case of alternating loads - different angular velocities and thus move different loads at different speeds with a uniform force. It can easily be seen from the particularly simple construction of the torque converter that it would be particularly suitable for driving motor vehicles, although conventional engine braking, with, for example, the lowest gear, when descending hills cannot take place with it. However this purpose is served in an effective manner by the overrun cut-off systems already installed in new models, which shut off the supply of fuel during overrunning - an economical and environmentally friendly device. This in turn provides an additional braking device (this is known) which, for example with a pedal arranged next to the accelerator pedal, can throttle the intake and/or the exhaust air of the engine as desired (i.e. also constitutes an instance of engine braking) and this simultaneously has the beneficial effect for the environment that the brake linings of the main brake system do not have to be used as often. <IMAGE>

Title: Wire helix for producing wire helix link conveyors and process and device for the production thereof
Inventor: LEO REINHARD
IPC: B29C53/12
Filed: 1984-06-13
Abstract: The invention relates to a wire helix comprising thermoplastic wire for producing wire helix link conveyors, in which the windings, in the untensioned state, are spaced from one another at most by the wire diameter and each winding has in a relatively stretched longitudinal lateral region of the substantially oval helix cross-section an enlarged section with enlarged wire cross-section. The invention also comprises a process and a device for producing this wire helix by helically winding a plastic wire onto a winding mandrel and stabilising the shape of the helix produced by heating. After heating to the stabilisation temperature, and before cooling, each winding is deformed by flattening externally between deformation rollers in at least one relatively stretched longitudinal lateral region to produce an enlarged section.

Title: Combined coupling and braking apparatus with creep speed drive for presses
Inventor: KREISL JOACHIM
IPC: F16D67/04
Filed: 1984-07-04
Abstract: The invention relates to a combined coupling and braking apparatus with creep speed drive for presses or similar machines. The aim of the invention is to devise a simple, operationally reliable solution to the problem of coupling the creep speed drive to the drive shaft of the press with use of a combined coupling and braking apparatus which is actuated by means of a pressure medium, by means of which solution full nominal force pressure can be reached at creep speed too. This gives rise to the object of forming the coupling and braking apparatus in such a way that, during operation of the creep speed drive, the coupling and brake can be simultaneously opened, thereby implementing direct coupling of the creep speed drive to the drive shaft (1). According to the invention, this is achieved in that another cylinder (15) is arranged inside the coupling and braking apparatus, in which cylinder a piston (16) is mounted which can be acted upon by a pressure medium during operation of the creep speed drive and acts to eliminate the force of pressure on the braking discs (5) independently of the pressure imparted by the coupling piston (12) to the springs (14). <IMAGE>

Title: Signal-forming circuit
Inventor: BUMKE DETLEF DIPL ING
IPC: G06F13/24
Filed: 1984-07-28
Abstract: The invention relates to a device which is intended to control the use of microprocessor systems in instrumentation. The device consists of a signal converter with a sensor, a voltage divider, a Schmitt trigger, flip flops, a monostable flip flop, an output for a computer connection, a channel number switch and with a tristate buffer. The measurement signal coming from the sensor is to be converted by a corresponding device into the instruction which causes the computer to start a fast or vectorised interrupt operation. For this purpose, the signal coming from the sensor is converted by the corresponding device into a TTL signal in such a manner that it is understood as interrupt signal by a connected microelectronic computer. The computer acknowledges this with an interrupt acknowledge signal to a device provided for this purpose in the signal-forming circuit. This device then outputs a particular preset bit sequence via a data bus to the computer, which bit sequence, in turn, causes a particular program to be started so that overall the vectorised interrupt operation of the computer can be controlled by the sensor.
