Abstract: A non-pyrophoric Raney catalyst composition comprises particulate Raney catalyst dispersed in a solid wax, fat or organic polymer which intimately coats the catalyst thereby rendering it non-pyrophoric. Suitably the composition comprises 40-80% of the catalyst and 20-60% of the fat, wax, or organic polymer. The composition is prepared by rendering wet Raney catalyst particles oleophilic by a surface active agent and dispersing the oleophilic particles in molten wax, fat or organic polymer and solidifying the composition.

Abstract: A wrapping machine for wrapping items of confectionery, such as lollipops (14) having an edible "pop" on a stick (15), includes various mechanisms for positioning these items in a desired configuration on a feed disc (11) and for repositioning them prior to wrapping and sealing a heat- sealable plastics material (26) around the edible "pop". A stick orienting mechanism traps the sticks in a desired position and elevates them by means of co-operating retaining members (27,28) operated by a shaft carrying a block with an angled face which is engageable by a bell-crank lever carrying an arm that engages and displaces a lollipop stick (15) into engagement with an abutment. A recess on the elevator member (27) and a recess on the counter-elevator member (28) reliably trap the stick (15) and wrapping material (26) between them, for transfer to a wrapping head.

Abstract: The toy has a geometrical body, bounded in its outer shape by flat surfaces, in the basic shape of a cube which consists of eight cuboid partial elements and in which in each case one element can be rotated along any half relative to its other half about one of the axes of a three dimensional system of coordinates which intersect in the mid- point of the regular geometrical body. The toy should have a regular shape which deviates from the previously customary cuboid shape and is thus given a more interesting and pleasant outer appearance without the number of combination possibilities being reduced. This is achieved in that a pyramid-shaped supplementary body (12, 13, 14, 15, 16) is placed so as to be rotatable on each of the outer surfaces of the cube, which supplementary body, together with the other supplementary bodies, makes the cube into a regular dodecahedron and consists of four symmetrical partial elements, the planes of contact of which coincide with the sectional planes dividing the cube into the cuboid partial elements. The pyramid-shaped supplementary body preferably consists of a truncated pyramid (17) with a pyramid tip (18) placed on top, the truncated pyramid and the pyramid tip being rotatable relative to each other on their contact surface. <IMAGE>

Abstract: A signal synthesizer provides high frequency synthesized waveforms for the user. By converting phase information into digital output signals in parallel and by selectively coupling these digital output signals, an ordered digital output signal is formed. This ordered digital output signal, which represents points on a sine function, is converted to a high frequency analog signal for the synthesizer output. …<??>Frequency and phase modulations of the synthesized waveforms are easily implemented with this novel signal synthesizer; the modulation information is simply added to the digital output signals prior to selectively coupling. Thus, when the ordered digital output signal is converted to an analog signal, the analog signal contains the modulation information.
