Abstract: Various packets slide down chutes or perpendicular shafts to come to rest on a tray from which a packet is fed to the customer. There are several of these trays at the bottom of each shaft, each located above a drive shaft which moves an ejector plate in circular path ensuring that a packet falls down the final track. The ejector plate is automatically actuated by a falling packet. A locking lever prevents blockage by other packets on the way. The locking lever which stops a continuous flow is also actuated by jolting or tipping the housing.

Abstract: In a paging system for hotel guests, use is made of the pigeonhouse-like structure (18), wherein keyholders (20) are deposited by the guests, for indicating to the telephone switchboard operator of the hotel whether a guest is available for an incoming call, rather than referring it to the reception desk (12). Each compartment of the structure is provided with keyholder presence/absence indicating means (24,26) which are coupled to the telephone switchboard (10). The absence of a keyholder will indicate that the guest is in his room, or that he is elsewhere on the hotel premises. In the latter case, the operator will transmit a paging signal to a receiver installed in the respective keyholder. Special requirements of guests may be accommodated through the use of dummy-keyholders, replacing the normal keyholders within the structure.

Abstract: The method comprises forming a cup-shaped blank defined by a cylindrical body, a radius portion and an end, and exerting first forces against the blank in a first direction to form the end into a concavely outwardly opening end defined by a central end panel (CP), a frusto-conical wall and an annular inwardly opening channel merging with the cylindrical body. The method then comprises exerting second forces against the annular channel in a second direction opposite the first direction while gripping the central end panel. The second forces deform a part of the frusto-conical wall in the absence of restraint out of the plane of the central end panel toward the interior of the can (B).  This forms an inwardly projecting outwardly opening annular bead.  The two directions define a single reciprocal opposing path of force exertion by the forces.

Abstract: In a displacement machine for compressible media on the spiral principle, the rotor disk (2) terminates radially flush with the displacement strips (3, 3'). So that the disk (2) can pass through the housing, in the inlet region (12, 12') of the machine the inner web (18, 18') of one housing half (7) is lowered by the amount of the disk thickness. To prevent leaks during the operation of the machine, the transition (19, 19') between the raised web (17, 17') and the lowered web (18, 18') is made circular. The rounding cooperates with a clearance (20, 20') in the form of an arc of a circle in the disk (2). Machines of this type are especially suitable for the supercharging of internal-combustion engines.

Abstract: A new process of synthesis of optically active  alpha -amino acids is described through nitrosation in a non-aqueous, aprotic system, of the corresponding N-carbamyl derivatives followed by decomposition of the thus obtained N-nitroso derivatives in aqueous acidic medium. The process, which is of a general applicability, leads to a remarkable increase in the reaction yields, due to the suppression of the main side reaction leading to the corresponding  alpha -hydroxy-acid. Some N-nitroso intermediates, which can be recovered from the process of the invention, are also described.
