A serial data word (e.g. sync preamble) is recognised by comparing with a predetermined datum word. The bits of the presented data are fed into the stages A to L of a shift register 6 which correspond to respective bits of the datum word. A monitoring unit 16 monitors the states of only those stages (stages D,G,I and K) corresponding to positions where transitions (0 to 1, or 1 to 0) occur in the ...

PURPOSE:To prevent the evolution of hydrogen gas from a cured silicone product, by contacting the product with a specified compound. CONSTITUTION:A resinous, rubbery or soft gel-like cured product obtained by curing a composition containing an organopolysiloxane having a lower alkenyl group such as a vinyl or allyl group and an SiH-containing organopolysiloxane as the principal components and plat...

The device for measuring stresses applied to a drilling tool comprises a removable instrument socket (2) secured by means of protuberances (15, 16) thereon to the wall of a compartment formed thereby in a shaft (OM) such as to make fast said socket and said shaft in two transverse planes (12, 13) and as to transmit to said socket the strains occurring in the shaft in response to the stresses to be...

An automatic reset arrangement for a manual release mechanism in a spring-applied, air-released brake comprising a sleeve member having axially projecting fingers that slide axially within the bore of the spring piston push rod. The ends of the projecting fingers are formed with outturned lugs having a conically-shaped surface adapted to engage a correspondingly-shaped shoulder in the bore of the ...

A cement composition contains calcium nitrite in an amount of 0.1 to 3.0 wt% based on cement and a thiocyanate in an amount of 10 to 200 wt% based on said calcium nitrite, and optionally an amino alcohol in an amount of 0.005 to 0.06 wt% based on cement. Owing to these additives, the cement composition sets and hardens rapidly and has improved non-corrosive performance.

An apparatus for determining the most economical purchase among products available in at least two sizes, and at different prices, in conjunction with a price reduction coupon, comprises a first register 34 for storing numerical values corresponding to product prices P1, P2, and sizes S1, S2, and the coupon value C, a keyboard 24 for entering the numerical values, means deducting, the coupon value...

In a vertical, form-fill-seal, wrapping machine, downward flow of charges of product, from a charge dispenser 50 to the wrapper tube 21, is assisted by utilizing the Coanda effect to establish a pulsed product- entraining flow of gas in a nozzle 23 in the pathway which leads from the weigher to the wrapper tube.

An automatic braking control system is capable of automatically maintaining a braking force once a vehicle has been stopped by the driver. The braking force is maintained until the clutch of the vehicle is engaged, at which time the force is automatically released so that the vehicle can be restarted. This system is especially useful for restarting a vehicle which has been stopped on an upward slo...
