Title: Cut crop windrowing machine - has guide walls to rotor rear hinging freely up and down in use
IPC: A01D78/10
Filed: 1974-10-01
Abstract: The lying crop is formed into a window between two contra-rotating tined rotors on vertical axes, and which deliver it between two vertical guide walls to the rear, hinging upwards on the frame. When in use, the walls hinge freely up and down, although means can be provided to restrict their downward movement.

Title: Glass fibre reinforced cement - treated with gaseous silicon tetra:fluoride to give improved retention of mechanical properties
IPC: C04B41/50
Filed: 1977-08-30
Abstract: Glass fibre reinforced cement composites with improved durability are made by treating the material with gaseous SiF4. The treatment is pref. carried out in an autoclave, until the Ca(OH)2 in teh inter filamentary spaced has been converted into CaF2. The treatment reduces the level of alkalinity of the prod. so that long term degradation of the glass fibres by the alkaline cement is reduced and the prod. retains its high initial mechanical strength for long periods. Conversion of the inter filamentary crystalline Ca(OH)2 into CaF2 reduces the physical pressure on the glass fibres and thus reduces mechanical damage to the fibres. The SiF4 penetrates deep into the interior of the body, in contrast to CO2 previously used. Treated prods. have improved resistance to household chemicals.

IPC: B08B3/12
Filed: 1986-08-15
Abstract: The invention relates to a process and device for the ultrasonic cleaning of rotationally symmetrical series parts, for example roller bearing rings, which can be used in mechanical engineering and apparatus construction with requirements for a high degree of cleanliness and integration into an automatic production process. The aim and object is an effective application of the ultrasonic cleaning process with the use of petroleum-like cleaning liquid and an intensive cleaning of series parts with ultrasound of high power density. The invention is characterised in that, in a container system surrounded by air, including an ultrasonic oscillator, an additional cleaning-fluid stream is effective in the direction of the conveyed parts to be cleaned. The container system consists of an intake container, discharge container and a tube which is arranged between them and accommodates externally a plurality of ultrasonic oscillators. The ultrasonic vibrations are directed into the petroleum-like cleaning liquid without the use of a coupling medium and with high electroacoustic efficiency, despite the subsequent intensive rinsing operation, the ultrasonic field retaining its full effect and a high cleaning action being exerted on the parts to be cleaned. <IMAGE>

Its employability is unlimited as regards to a user's age. The apparatus is appropriate for individual and group training, for use on open air or indoors, in apartments, kindergartens, schools, gyms, on playgrounds, military polygons and in special-purpose rooms. The apparatus built according to this invention behaves as a live being, it pleasantly challenges, surprises and stimulates a gymnast to use as much of her/his psychical and physical capacities as possible and as such gets even most passive users into training. Competitions on this apparatus are very attractive for competitors and for spectators since it perfectly suits the human nature. With regards to attractiveness and freedom of movement, training on this apparatus gets close to a game-level, activity and freedom which so far have been feasible on a mass-scale in water only. The apparatus is intended for training ashore. A base (1) can be fixed into any spatial position. One or more radially and torsionally flexible branches (2) spring out of the base. Thinner branches of the same characteristics (3) spring out of branches (2) and so on. Branching can be done according to someone's wish. Training possibilities can be extended by combining several differently spatially disposed apparatuses.
