Title: Skin massage apparatus with simultaneous application of a cosmetic product
Inventor: KAESER CHARLES
IPC: A61H7/00
Filed: 1982-04-28
Granted: 1985-09-12
Abstract: A skin massage device for both massaging skin and applying a cosmetic product through retractable protuberances on the massaging surface. A first plurality of the protuberances are retractable into the massing surface, and include a piston with an outlet opening in its exterior side. A rod affixed to a housing in the massaging surface is engaged by the piston and this seals the opening. Upon massaging pressure applied to an annular bead on the piston, the piston is retracted into the massaging surface, opening the piston opening and permitting exit of cosmetic product. The piston extends into a housing supported at the massaging surface and the housing communicates into the reservoir for being filled. The piston includes a side wall which blocks communication between the housing and the reservoir when the piston is retracted, whereby cosmetic product in the housing is forced out the opening in the retracted position of the piston.

Title: Apparatus for transmitting and/or receiving microwave radiation
Inventor: GUY RONALD FRANK EDWARD
IPC: H01Q21/22
Filed: 1982-11-16
Granted: 1986-05-15
Abstract: Gain characteristics can be achieved by displacing the position of maximum amplitude to a base region of the antenna but maintaining a lesser amplitude peak in the central region. This is as shown in continuous lines in Figure 3A. Also the phase distribution is changed so that the phase lag increases relatively slowly in a lower base region and relatively fast in the central and upper regions of the antenna. This is as shown by the continuous line of Figure 3B. This continuous line has a distinct bend in the upper half of the base region in contrast to the two bends 1 and 2 of the conventional phase distribution shown in chain dotted lines.

Title: Control and signal transmitting device for transportation systems
Inventor: BOGLI PETER
IPC: B61L3/12
Filed: 1983-10-05
Granted: 1987-06-11
Abstract: Transponders are arranged at control locations associated with sections of a track or travel path. Each transponder is in wireless communication through an inductive transmission path and an optical transmission path with a conveyor present in the operable range of the transponder. Each transponder is in communication with a central system control via an associated group control unit by means of two-wire lines or conductors. The operational mode of each transponder is controllable by means of a multiplexer such that the transponder operates either as a responder or answering device with simultaneous unidirectional signal transfer and which responder is to be interrogated by a conveyor or as a bidirectional signal transmitter. The apparatus selectively functions as a location or site code transmitter and presence indicator for the individual conveyors or as bidirectional data transmitter with isolated directions between the conveyors and the central system control. Due to such dual utilization only one type of layout element is required, resulting in a high reduction in the installation expense and its maintenance. The apparatus is intended for the modular erection of conveyor installations of different sizes and output and is equally well suited for partially autonomous as well as for central control of the conveyors.
