Patent DE-3839391-A1 (DE)
Inventor: STEARNS KENNETH W
IPC: A63B22/02
Filed: 1988-11-22
Abstract: A treadmill has a belt system carried by a platform structure 16. The platform structure is pivotally mounted at its rear end to a base structure. The platform is supported at its forward end by a shock absorber/spring system 32, 36 which provides a dampened resilient response of the belt and platform when a person's foot lands during running or walking. Carrying the belt system by the platform structure enables the endless belt of the belt system to be maintained closely above the platform even when a runner's foot lands on it with heavy impact. The support of the platform immediately below the belt eliminates lateral slack in the belt, which could possibly result in injury to a walker or runner due to an uneven landing surface. <IMAGE>

Title: Device for emptying refrigerating sets
Inventor: GRUENEISEN WERNER DIPL ING
IPC: F25B45/00
Filed: 1989-01-09
Abstract: The invention relates to a device for emptying refrigerating sets, with which the medium intended for refrigerating can be removed from the refrigerating circuit. The aim of the invention is to empty refrigerating sets of all kinds in an environmentally friendly manner. The invention consists essentially in that a seal is provided, which surrounds a line of the refrigerating circuit, in that the line can be perforated in the region of the seal with the aid of a perforating punch which is movable perpendicularly to the longitudinal axis of the line, and in that the medium for refrigerating can be removed via a line system. The advantages achieved with the invention consists in particular in that the refrigerating medium which is situated in the refrigerating circuit of refrigerators or deep-freeze arrangements, but also lubricating oils, can be removed in an environmentally friendly manner. Once this has taken place, the possibilities arise of treating the removed chemicals and supplying them for reuse. Moreover, the metal parts, e.g. of a refrigerator, can be scrapped without concern and the scrap utilised.

Patent DE-3901223-A1 (DE)
Title: Espagnolette lock
Inventor: KAUP LUDGER
IPC: E05B15/00
Filed: 1989-01-17
Abstract: In an espagnolette lock, the espagnolette is moved from a lock cylinder via a reduction gear between an opening position and a closing position, and vice versa. There is proposed a coupling of the reduction gear to the espagnolette which makes it possible, during the rotation of the lock cylinder through 2.360@, to displace the espagnolette from the opening position into the closing position and to block the espagnolette in the closing position against displacement, without a torque being introduced into the reduction gear and therefore into the lock cylinder by blocking forces.

Title: Flow meter with cut-out measuring flap
Inventor: DJORDJEVIC SLAVOLJUB
IPC: G01F1/26
Filed: 1989-02-27
Abstract: A flow meter with cut-out measuring flap is used for flow measurements of liquids and gases in closed pipework. In contrast to existing devices, the novel measuring flap distinguishes itself by covering only a part of the opening of the fitting with cut-out(s) or openings (in the flow direction) and thus opening up new perspectives in measuring technology. One of the problems existing until now: especially in the case of large measuring devices it is known that the measuring flaps were destroyed in the event of recoil in cases of liquid interruptions. This problem has thus been solved by this novel invention. Furthermore, a higher measured quantity and accuracy are achieved.

Title: Continuous vol. measurer for liquids of low viscosity and gases - comprises displacement counter magnetic coupling and servomotor with pulse scanning
Inventor: PEGE LOTHAR
IPC: G01F15/02
Filed: 1989-05-12
Abstract: The displacement counter (1) with an inlet (2) and outlet (3) for the medium to be measured is driven by the servomotor (5) via a magnetic coupling (4). A pulse scanner (6) forms a unit with the motor. The signal frequency delivered by the former is  proportional to the vol. of the stream flowing through the counter per unit of time. After passing a pulse shaper (7), this signal frequency appears at the terminal (8) as a measurement signal as well as at the input of the function generator (9) as a control signal. This function generator presents the approach to the characteristic of the counter (1) as U1 = f(Q,n). U1 is the input value for the amplifier (10) at whose output a voltage U2 = f(Q,n) appears. ADVANTAGE - Simple conception with servo-drive but without separate differential pressure detection. High precision even at flows below 1 1/h. Allows adjustment of average calibration factor to uniform value.
