Title: Training bar for muscle training
Inventor: HUBER IGNAZ
IPC: A63B21/072
Filed: 1988-03-30
Abstract: In order to be able to carry out comprehensive muscle training with weight discs, many dumbbell bars are needed, for example long, short, SZ and pull-up bars. The disadvantage of these bars resides in the fact that they cost a great deal of money and, because of their rigidity, impose very heavy loads on the joints in various exercises (e.g. pull-ups). The invention relates to a training bar with ball-bearing rotating handles whose spacing can be set by the screwing-in of 1'' steel pipes of various lengths. Weight discs can be pushed onto the welded-on 30 mm 0 steel pipes and fixed with snap-fit closures. The training bar can also be mounted as a pull-up bar with the aid of spreader plates in a door frame. In addition, the two rotating handles can be used as individual dumbbells after removal of the 1'' connecting bar. Comprehensive muscle training with weight discs, using a single training bar, and maximum possible relief of stress on the joints. Rapid replacement of the weights combined with high durability and without damage to the receiving bar caused by snap-fit closures. <IMAGE>

Title: Method for controlling the lye pumping-off operation in washing machines
Inventor: ANKELMANN WOLFGANG DIPL ING
IPC: D06F33/42
Filed: 1988-07-27
Abstract: Method for controlling the lye pumping-off operation in washing machines. The lye-pump feed is to be matched to the quantity of waste spinning water occurring. Appliances available on the market control the lye pump via permanently predetermined time profiles by means of a programme-switching unit. The "on" and "off" times of the lye-pump are not synchronous with the quantity of waste spinning water, so that the idling pump sucks up air and does not transport the lye away. As a result of the solution according to the invention, the lye-pump feed is matched exactly to the quantity of waste water occurring. The current consumption of the drive motor (8) is monitored constantly and is fed as an input signal (11) to electronics (10). Desired values corresponding to the current consumption of a full-feed lye-pump (5) are stored in the electronics (10). By means of an actual/desired value comparison, the electronics (10) decide whether, via an output signal (12), the drive motor (8) is briefly switched off intermittently during idling and remains switched on during full feed. The method is suitable for domestic washing machines which have lye-pumps driven by synchronous motor. Moreover, it can be used in dishwashers having the same lye-pump drive motors. <IMAGE>

Title: Process for removing impurities from AlSi casting alloys
Inventor: BEEL GUNTER DR
IPC: C22B9/02
Filed: 1988-09-08
Abstract: According to the currently usual processes for the removal of hydrogen, oxides and other impurities from aluminium alloys by vacuum degassing or vacuum purification, hitherto only charges of at most 1.5 tonnes can be effectively purified in one crucible. The novel process is intended to permit efficient purification of the AlSi casting alloys having charge weights of up to 5 tonnes in a single crucible. According to the proposed process, the molten AlSi is subjected, after two-stage vacuum treatment assisted by flushing gas, to a vibration treatment or shaking treatment for several hours. In this way, it is possible markedly to reduce the gas content and/or impurity content of the melt and hence considerably to improve the quality of the cast alloy. Refining of AlSi casting alloys.

Patent DE-3840265-A1 (DE)
Title: Programme-controlled washing machine
Inventor: STAMMINGER RAINER DIPL PHYS DR
IPC: D06F39/06
Filed: 1988-11-30
Abstract: Programme-controlled washing machine with a laundry drum which can be driven by a motor in the washing and spinning mode and which is located inside a tub, out of which the washing and rinsing lye can be discharged by means of an emptying pump arranged in a flow-off conduit, and with electronics which control the laundry-drum drive motor and by means of which the rotational speed of the laundry drum in the spinning mode is increased in small steps or stages and, when foam forms in the tub, is reduced correspondingly. For the purpose of recognising the risk of the formation of foam during the spinning operation, each spinning-speed increase step or each spinning-speed increase phase is concluded with a spinning-speed measurement or a load-moment measurement. The particular actual spinning speed measured thereby is compared with a predetermined desired spinning speed or the measured load moment is compared with a predetermined load-moment value. On the basis of a recorded or detected speed difference or an ascertained load-moment change, the next predetermined desired spinning speed is reduced. After the reduced spinning speed has been reached, only then is an increased desired spinning speed predetermined again.

Patent DE-3939256-A1 (DE)
Inventor: KOSIKOWSKI THOMAS DIPL ING
IPC: C25D17/06
Filed: 1989-11-28
Abstract: Prior art holding and electrical-contact devices of this kind can suffer from undesired metal deposits in the holding or contact zones, particularly if they are passed through the electrolytic bath without holding a component. In order to remove deposits of this kind, the prior art calls for the holding and electrical-contact device to be passed through a metal-removing chamber after passing through the bath. The invention substantially prevents metal coatings of this kind from forming when a holding and electrical-contact device is passed through a bath without holding a component. To this end, a seal is formed between the two gripping elements (3, 5), thus sealing off the holding and electrical-contact zones (7, 15, 9, 17) against penetration from the outside and essentially preventing these zones from being wetted by the electrolyte.

Title: Glass optical fibre doped with rare earth elements - acts as pumped laser in which element is present to enhance laser transfer of the dopant thulium
Inventor: SCHNEIDER HARTMUT DR
IPC: H01S3/067
Filed: 1990-09-11
Abstract: Optical fibre consists of a glass, pref. an oxygen-free fluoride glass from the gp. of heavy metal-fluoride glasses (HMF) or quartz-glass, which is doped with thulium, pref. less than 0.1 mole%. The feature is that the glass also contains dopant of another element at a relatively higher doping level, pref. up to 50x, which shows an energy-term ((5)I7,(7)F2,(7)F6) which is close to that of the term (3)H4 of Tm. The other dopant(s) pref. also has (have) multiple energy terms, e.g. (7F3) to (7)F6 for Tb and (7)F5 to (7)F0 for Eu, which effect a multi-phonon emission. USE/ADVANTAGE - The use of codopants causes deactivation of the (3)H4 level of Tm, which is present in lower concn. the output. The use of multiphonon emission reduces deactivation of the (3)F4 level by acceptor states, which can have high lifetimes. The inter-ionic transfer between Tm and e.g. Tb causes a redn. of the occupation density of the laser level. The laser is used for optical fibre communication, at a wavelength of 1.5 microns.
