Title: Haulage or lifting mechanism with automatic brake - has hand operated secondary shaft releasing brake
IPC: E05F15/10
Filed: 1974-05-08
Abstract: The winch drum is driven by an electric motor and the brake consists of a member fixed to the winch shaft and a second and non-rotating spring-loaded member pressed against the first member. The brake is released by an electromagnet in the motor circuit. A secondary shaft is rotated by a manually-operated mechanism and also caused to slide axially under the effect of a cam mechanism. Sliding of this shaft engages it with the shaft carrying the brake member, whereupon a plate on the secondary shaft pulls the second member free of the first. Thus the brake can be released to lower the load in the event of failure of the electric supply.

Abstract: The sensitivity of a positively-acting photo-resist material contg. a PF resin and a diazonaphthaquinone inhibitor to actinic or electron irradiation is improved by addn. of a sensitiser. This is a cpd. from one of the gps: (a) unsubstd. aryl- or N-acyl-substd. arylsulphonamides of formulae Ar.SO2.NH2, Ar.SO2.NHR or Ar.SO2.CO.NHR respectively, where Ar is any aryl residue and R = alkyl or aryl, (b) N-acyl substd. carboxylic amides of formula Ar.CO.NH.CO.R1 where Ar has same meaning and R1 = alkyl or aryl, and (c) cyclic sulphonic or carboxylic amides of formulae: where Ar is again aryl. Method can be used in prepn. of positive photo-resistant coatings, partic. in connection with micro-circuitry. Previously proposed sensitisers increase the sensitivity of the coating to irradiation but seriously reduce the storage stability. Those of the invention give high contrast between irradiated and unexposed areas without this disadvantages.
