Title: Composite athletics track - of rubber covered bitumen with a microcellular filler to reduce muscle damage to runners
IPC: E01C13/06
Filed: 1970-03-16
Abstract: A synthetic track comprises a substrate layer of bitumen, incorporating, among other fillers, elastic and compressible microcellular particles (such as cork), and a rubber-based cover is not >1 cm thick which does not contain compressible microcellular particles, which cover may incorporate flakes or chopped pieces of (solid) moulded rubber. Prod. is esp. suitable for construction of tracks for sports grounds, walk ways or festivals, and provides a smooth impermeable surface which is sufficiently flexible to deform under the impact of a runner's feet. The relatively slow recovery of the bituminous layer delays the reaction of the elastic components so that the runner's muscles are not subjected to a damaging energy rebound.

Title: Automatic duct sealing equipment - gas press. ejects sealant from container on detection of abnormal conditions
IPC: A62C2/06
Filed: 1973-07-12
Abstract: This equipment prevents the spread of fire or noxious fumes along ducts containing electrical cables, water pipes or used for air conditioning.

Title: High intensity mercury vapour lamp - with outer tube coated with red emitter and yellow pigment
IPC: H01J61/44
Filed: 1974-05-07
Abstract: High intensity reducing vapour lamp comprises an arc tube which emits radiation deficient in red light, and an exterior envelope with a composite layer on its interior surface contg. a red emitter and a yellow pigment. The luminescent matl. is suitable for use in the lamp range 300-400 degrees C, conconverts the UV produced by the mercury discharge to visible light and serves to correct the red deficiency in the light emitted by the arc tube, but gives a violet appearance to the lamp. In the blue region of the spectrum the yellow pigment produces an absorption effect to shift the colour point of the lamp in the blade body direction of the curve, while being transparent to the green and yellow rays of the mercury discharge at 540 and 570nm. Colour rendition is improved without loss of lamp brightness.

Title: Collapsible high chair for infants - has disengagable screw jack for stability and height adjustment and two part nut which diengages radially
IPC: A47D1/02
Filed: 1975-05-28
Abstract: The collapsible high chair for infants has scissor type articulating support frames. A disengageable screw-jack mechanism which stabilises the extended frames is used for minor height adjustments. The screw-jack has a screw (20) passing through a two segment (21) conical type (21) mounted in a tapered aperture (19) in a transverse member (15) on top of the folding frames and under the seat. This screw (20) may be mounted free to rotate on the underside of the chair seat and may be rotate by a crank handle.

Patent FR-2295532-A1 (FR)
IPC: G06F12/16
Filed: 1975-12-16
Abstract: A maintenance procedure comprising a method of and an apparatus for storing information identifying the location of one or more defective bits, i.e., a defective memory element, a defective storage device or a failure, in a single-error-correcting semiconductor main storage unit (MSU) comprised of a plurality of replaceable large scale integrated (LSI) bit planes. The method utilizes an error logging store (ELS) that is comprised of a plurality of word-group-associated registers which hold the address data that identifies the replaceable LSI bit planes of the MSU in which a correctable error has been detected. After each detection of a correctable error, the address data is compared to address data already stored in the ELS. If the comparison indicates that it is new address data, i.e., that that bit plane has not previously caused a correctable error, the address data is entered into the ELS, shifting all previous entries one stage. After a predetermined number of defective bit plane addresses, i.e., address data, are stored therein a signal is generated to alert the machine operator to schedule preventive maintenance of the MSU by replacing the defective bit planes. By statistically determining the number of allowable failures, i.e., the number of correctable failures that may occur before the expected occurrence of a non-correctable double bit error, preventive maintenance may be scheduled only as required by the particular MSU.
