Abstract: 1455328 Alarm clocks KIENZLE UHRENFABRIKEN GmbH 2 April 1974 [3 April 1973 6 April 1973] 14519/74 Heading G3T [Also in Division H1] An alarm clock which produces an electric alarm signal at a pre-selected time and which operates in association with a manually controlled electric auxiliary device, such as a lamp, has a common contact spring 7 of which different portions 17 and 18 are moved to open and close respective circuits for the alarm signal and auxiliary device. As shown, the spring 7 is secured to a printed-circuit board 16', and has one end 18 bent over a fixed contact 19 and the other end 17 restrained from engaging a fixed contact 14 by a shoulder 6 on a member 5 which is screwed into a unitary alarm member 2 rotatable and axially movable on axis B-B. An arm 4 integral with member 2 acts as a follower on an hour wheel 11 which moves axially at a pre-set alarm time when a stud thereon moves into alignment with a recess 12 in an alarm tripping wheel 13. A nose 8 of another arm on member 2 prevents member 2 from dropping since it overlies the top of a fixed inclined surface 9, but if a button (10) Fig. 2a (not shown) is rocked to an alarm set position it acts on yet another arm 1 on member 2 and rotates it such that nose 8 overlies the lower part of incline 9 and members 2 and 5 can drop at the pre-set alarm time to close contacts 17, 14. Movement of button (10) in the reverse manner cancels the alarm by urging nose 8 up incline 9 and lifting member 2 to open the contacts 17, 14. The button (10) can also be moved to a third position wherein a projection (20) pushes contact 18 into engagement with contact 19 for energizing the lamp, the spring 7 opening the contacts when the button is released.

Abstract: A hydrogenation catalyst is prepared by treating a liquid dispersion or solution containing a copper compound and metallic palladium with a reducing agent (preferably hydrogen or hydrazine, but also e.g. hydroxylamine) so as to deposit metallic Cu on the Pd, the latter preferably being supported on an inert carrier such as carbon (preferably charcoal), aluminium or silica.  It is preferred to use an aqueous solution of a Cu salt, particularly the acetate, but also e.g. the sulphate, chloride, nitrate, cyamide, formate, carbonate or oxide, in dispersion or solution. The catalyst is preferably utilized for the conversion of 1 : 4-butynediol to 1 : 4-butenediol: it is stated that the catalyst may be used also for converting nitro-compounds to amines, ethylenic to saturated compounds, carbonyl compounds to alcohols and particularly acetylenic to ethylenic compounds.  U.S.A. Specification 2,319,707 is referred to.ALSO:1 : 4-Butynediol is converted to 1 : 4-butenediol by use of a catalyst prepared by treating a liquid dispersion or solution of a copper compound and metallic palladium with a reducing agent (e.g. hydrogen, hydrazine or hydroxylamine) to deposit metallic Cu or the Pd. Preferred conditions for the conversion are (a) use of 1 equivalent of H2; (b) about room temperature-100 DEG  C., particularly about 40-75 DEG  C.; (c) about 1-20, particularly about 3-10 atm.  In an example, a catalyst slurry prepared from 5% Pd on charcoal, and aqueous Cu acetate at 40 DEG  C. under 75 p.s.i.g. of H2 was used to hydrogenate three successive portions of 38.3% aqueous butynediol at 40 DEG  C. and 75 p.s.i.g., each reaction being stopped when 95% of 1 equivalent of H2 had been added (5 hours).
