Patent DE-2925447-A1 (DE)
Title: Silicate glass fibres with high silica content - obtd. by leaching out oxide(s) other than silica, and then treating fibres with soln. of colloidal silica
Inventor: WEBER EKKEHARD PROF DR ING
IPC: C03C25/00
Filed: 1979-06-23
Abstract: The initial fibres are treated with an extn. soln. to dissolve out oxides other than SiO2. During or after this extn. treatment, the fibres are treated with a soln. (I) contg. colloidal- silica or -polysilicic acid, or silicates, so the wt. ratio of SiO2 w.r.t. the other oxides is increased. The colloidal soln. (I) may be used for different times and/or temp., and with different concn. of the SiO2 or silicates in soln.; and acids may be added to promote deposition of SiO2 on the fibres, esp. when using an aq. soln.(I). Soln. (I) may also contain metal cpds. so metals are also deposited on the fibres. The invention increases the SiO2 content of glass fibres, and therefore increases their strength at high temps. The SiO2 also fills the fissures caused by the extn. of other oxides, e.g. Al2O3, CaO, Na2O, K2O, so the tensile strength and toughness of the fibres are both increased. The resistance of the fibres to chemicals is also improved.

Title: Termination of nickel-cadmium battery charging process - by detecting terminal voltage peak which occurs when fully charged
Inventor: KONRAD HORST ING GRAD
IPC: H02J7/00
Filed: 1979-11-30
Abstract: The application is principally to fast charging of nickel cadmium cells for model or toy power supplies. In particular it is useful for batteries with sintered electrodes. To determine the fully charged state, use is made of the voltage peak coincident with a state of full charge which is a characteristic of the cell. The cell voltage is continuously monitored, and the charge switched off when the peak is detected. In a practical design the voltage is converted into a voltage dependant frequency and applied in successive equal time intervals to an up-down counter. If at the end of such a cycle the count is greater than zero the battery is assumed to be charged and the charger switched off. This monitoring method overcomes the strong temperature dependence of the voltage peak.

Patent DE-3043108-A1 (DE)
Title: Clamp for flexible hose connection to valve - has longitudinal opposite ends of narrowed portion defined by inclined linear edges
Inventor: HASHIMOTO SEIICHI
IPC: F16L33/03
Filed: 1980-11-14
Abstract: The clamp is useful for connecting fluid-conveying hoses and the like to couplings, and valves. The clamp is formed of a spring metal strip (10) which has portions of its longitudinal parallel linear edges (12) cut to provide a pair of parallel inclined linear edges (14). The original constant width of the strip is gradually reduced toward the longitudinal opposite ends of the strip so that the width of the strip varies in proportion to the bending moment produced in the strip. The thus narrowed opposite ends being bent in mutually opposed relation provide operating knobs (16) for forcibly spreading the ring diameter. The spring metal strip thus prepared is then wound into a ring of right circle, with the inclined linear edges abutting against each other along a given length, thereby ensuring uniform beinding stress throughout the ring.

Title: Fluid store heated by two heat sources
Inventor: TENHUMBERG JUERGEN DR
IPC: F24H1/18
Filed: 1981-01-08
Abstract: The present invention relates to a fluid store which is heated by two heat sources and in the storage space of which at least one heat sensor is provided. The object on which the present invention is based is, starting from a fluid store heated by different heat sources, to switch on only the actuator of one heat source when only a small quantity of service water is tapped, whilst the actuator of the other heat source is loaded when a larger quantity of service water is tapped. This object is achieved, according to the invention, in that each heat source is assigned a heat sensor, and these are arranged at respective different levels. The advance arising from this is that one heat source, which works economically, for example, only over longer operating times, is used only when longer operating times are to be expected. In contrast, the other heat source, which is more expensive over longer operating times, can advantageously be used for short-term operation.

Title: Device indicating the presence of safety strips in a surveillance area
Inventor: HARTMANN ERNST-GERHARD
IPC: G08B13/24
Filed: 1981-01-16
Abstract: A device indicating the presence of safety strips in a surveillance area, particularly for the purpose of preventing shoplifting, comprises resonant circuits containing air-core coils, which generate electromagnetic fields due to electrical excitation in the surveillance area. Interaction of these electromagnetic fields with existing safety strips is detected by detection likewise coils constructed as air-core coils. To prevent an inadmissible increase in the field strength due to sensing coils (L) being arranged spatially adjacently to one another in multiples, in the event of an increase in the number of surveillance areas, the sensing coils (L) spatially arranged adjacently to one another are alternately polarised in opposite directions in pairs. <IMAGE>
