Abstract: 403,545. Playing cards. WHELAN, T., 23, St. Patrick's Villas, Ringsend, Dublin. March 16, 1933, No. 7939. [Class 132 (ii).] The playing cards of a pack each have a miniature representation of the conventional suit and value markings surrounded by wide margins at the edges of which may be suit indications 5 and suit and value indications 6. This arrangement is devised to make it more difficult for a player to see his opponent's cards. The cards may be of metal or of white paper with a black lacquer finish at the back, so that any attempt to mark the card would become apparent by the peeling-off of the black lacquer to reveal the white paper.

Title: Clock synchronizable from alternating current and a transmitter for use therewith
IPC: G04R40/02
Filed: 1972-02-22
Abstract: 1342206 Electric clock systems DIEHL 22 Feb 1972 [2 March 1971 (2)] 8053/72 Heading G3T A clock comprises an electro-mechanical oscillator - tuning fork 22 Fig. 3 - which is magnetically coupled to the clock movement and time indicator. The fork oscillations are maintained and synchronized to mains frequency by amplified synchronized pulses received wirelessly from a transmitter which is electrically connected to the mains. In the event of large deviations e.g. 0À15 Hz between the synchronized pulse frequency and the tuning fork frequency, or in the event of mains failure, a drive circuit (which also acts as a synchronizing circuit) including - an oscillation amplitude regulating transistor 25, operating transistor 24, drive coil 21a and a pick-up coil 21b, takes over the drive at the natural frequency of the fork. The drive circuit is energized by a battery in the clock. The transmitter Fig.6 is an electronic module the size and form of an outlet plug and is pluggedin to a socket in the same building as or vicinity of the clock. The transmitter produces a 25 KHz carrier modulated by impulses at twice the mains frequency (i.e. at 100 Hz) from a full wave rectifier 35, a glow tube 36 passing only wave portions above a threshold voltage, e.g. above the mains R.M.S. voltage amplitude, to a ferrite antenna 34. Instead of using the glow discharge tube the rectifier bridge may include a respective Zener diode 37, in at least two arms. Thereby the modulating waveform will have sufficiently wide keying gaps between pulses as, illustrated Fig. 5 (not shown). The transmitted wave, is picked up by a ferrite rod antenna on the clock and applied to the base of a transistor 20.
