Title: Clutch operation for drive belt pulley - applies tension to belt to transfer drive to pulley
IPC: F16D13/10
Filed: 1974-03-25
Abstract: The pulley consists of two formed metal disc halves (2, 3) both mounted solidly on a shaft (1), and forming between them at their outer peripheries a diverging angle to receive the drive belt (10). An elastic annular disc (8) lies between these two pulley halves and rotates freely round the pulley shaft on a ball bearing (7). In its normal position the disc stands proud of the pulley vee and, when the belt revolves with no tension, carries the belt. When tension is applied to the belt, the disc deforms radially inwards, and the drive is transmitted to the pulley shaft.

Title: Visibility system for SECAM-TV colour bars - has colour-level for yellow and blue colour-bar region
IPC: H04N9/04
Filed: 1975-03-06
Abstract: The visibility system improves the visibility of the edges of colour bars in a SECAM television system.

Title: Sputtering metal coatings onto razor blade edges - then etching with flourine before applying a film of PTFE
IPC: C23C14/34
Filed: 1975-04-10
Abstract: A metallic coating is formed on the cutting edge of razor blades by cathodic sputtering using a d.c. voltage, and then a fluorine polymer film is deposited. The novelty is that during cleaning and sputtering, a polarising voltage is applied to the blades, creating a high ionic density at the level of the blades, and the metal coating is etched at low temp. with fluorine gas before depositing the film of fluorine polymer. A triode sputtering appts. is pref. used with a negative cathode voltage of 600-1200 V; positive anode voltage 100-200 V; and a negative voltage on the blades of 50-10V. The distance blades to cathode is pref. 3-10, esp. 50-100V. The strength and corrosion resistance of the edge of the blade is increased and the adhesion of the polymer is improved, the polymer increasing shaving comfort.
