Abstract: 2-pyrrolidones are prepared by hydrogenating a succinonitrile in the liquid phase in the presence of ammonia by passing an ammoniacal solution of a succinonitrile over a fixed bed catalyst, particularly of the trickle-phase type, in which the catalyst is nickel on an alkaline support such as calcium hydroxide or calcium carbonate. Attractive yield are achieved without the expense of filtering off and separating used catalyst as in prior procedures.

Abstract: Unsaturated fatty acid derivatives which, besides fatty acids with two double bonds, contain fatty acids with more than two double bonds, are hydrogenated in the presence of a palladium, platinum or rhodium catalyst which has been treated with ethylenediamine or a homologue and/or a derivative thereof and at a temperature of -20 DEG to 100 DEG  C. The hydrogenation progresses very selectively while very little isomerization to trans-fatty acids occurs. For example, in the hydrogenation of soya bean oil to a linolenic acid content of 2%, the linoleic acid content only decreases to 45-52%. Under identical conditions an untreated catalyst leads to a linoleic acid content of about 35%.

 wherein R<1> and R<2> are hydrogen or methyl or ethyl groups and Y is a pyrazine or pyridine radical corresponding to the structures: 
<CHEM>
 and any adjacent R<1> and R<2> when taken together with connecting elements form an alicyclic structure. Under smoking conditions such polyheterocyclic compounds flavour mainstream and sidestream smoke. Additionally such compounds will flavour foodstuffs when incorporated therein or when the foodstuff, for example meat, is contacted with gases produced by combustion of a material containing the compounds. The polyheterocyclic compounds will also enhance the aroma of burning combustible articles such as candles or solid fuel.

IPC: A63F5/00
Filed: 1980-10-09
Abstract: In a fruit machine, means sensing the positions in which symbol carriers (R) stop can accommodate rotation of the carrier in either direction. 
     Associated with each carrier, two photo-electric cells (P1, P2) are each arranged to receive pulses of light from a light source through one of two series of apertures (S) in a disc (D) which rotates with the carrier (R). The apertures are formed so that the cells (P1, P2) generate two trains of electrical pulses of the same frequency but out of synchronism. The pulses are fed as an activating signal to a counter which changes its state in step with rotation of the carrier. Since the trains are out of synchronism, the signal is assymetrical in time so that reversal of the rotation of the carrier causes a different signal to be sent to the counter. The two signals cause adjustment of the counter by an increment and a decrement, respectively.

Abstract: A magnetic chuck or holder for workpieces adapted to be mounted on a worktable of a machine tool comprises a stack of alternating permanent magnets and magnetically conducting plates having a central passage through the stack in which a second stack of magnets and magnetically conductive plates is received for longitudinal movement, e.g. by a crank or an eccentric drive cooperating with one end of the second step. The two stacks are so arranged that they magnetically cancel the magnetic field lines on the upper, lateral and bottom surfaces of the chuck in one position of the second stack but create such field lines in a second position that all surfaces of the upper, lower and lateral surfaces are magnetically effective. This allows switching of the chuck to an effective state so that a workpiece is affixed magnetically to the upper surface of either or both lateral surfaces, and at the same time the chuck is magnetically fixed on the worktable of the machine tool.

The larger diameter anchoring part (6) formed at the end of the attaching side of the spike body (4) is larger than the end part on the ground touching side of the spike body (4), but has a diameter smaller than 1.5 times that of the latter. This larger diameter part is wholly coated with plastics, and is unified with the outer circumferential part of the spike body (4) extending contiguously to the end part on the ground touching side through a smoothly tapered or arc-shaped joining surface (7).
