Title: An improved projection advertising device
IPC: G09F19/18
Filed: 1923-12-10
Abstract: 223,432. Osborne, F. L. Dec. 10, 1923. Elements moving always in one plane, rotating; optical-projection apparatus, applications of. -In apparatus of the type in which a member carrying advertisements &c. is intermittently rotated by clockwork which is released at intervals by a separate continuously moving clockwork train, means are provided for stopping the two sets of clockwork after a predetermined period. The means comprise a slotted disc 7 adjustably fixed on the shaft 14 of one of the toothed wheels 6 of the intermittently moved train which actuates a disc 5 carrying e.g. slides 4 for opticalprojection. A lever 9 pivoted near its middle carries a pin 11 which bears against the rim of the disc 7 and eventually enters the slot 8 by reason of the weight of the other end 10 of the lever 9, thus stopping the mechanism. A hooked rod 26 connected to the end 10 is simultaneously pulled down and stops the continuously moving train by engagement with the teeth of wheel 27. A spring-pressed switch 12 is also released by the end 10 to extinguish the light. The mechanism for intermittently stopping and releasing the advertisement operating train consists of a notched disc 16, Fig. 3, mounted on the said train and engaged by a bell-crank 18, 20 pivoted at 19. A swinging arm 22 bears on the leg 20 to release the disc 16, being engaged by a cam or by pins 23 on a spindle 24 of the constantly rotating train. The gear wheel 16<a> of the intermittently-moved train is given an initial impetus by a toothed wheel 33 carrying a depending hook 32 which is pressed by an arm 31 before the disc 16 is released by the leg 18. When the apparatus is adapted for optical-projection, one or more coloured transparent discs 28 located in the light beam is driven, e.g. by belting 29, from the continuously moving clockwork train. When several discs are employed they may be on one or several spindles and may rotate in the same or opposite directions at any relative speeds.

Abstract: 1411507 Selective signalling SIEMENS AG 2 July 1973 [28 Aug 1972] 31376/73 Heading G4H [Also in Division H4] A control system for controlling a device in dependence upon command words and characteristics assigned individually to the command words, comprises a store with a plurality of storage blocks, the store emitting consecutively, in respect of each command word applied to it, one substitution address and at least one control word which is used in controlling the device, command words which are assigned different characteristics being assigned to different blocks, part at least of the substitution address being stored in a register until all the control words assigned to a command word have been conducted to the device, the information in the register being used to control the device.  Two bits of a 7-bit character to be traced out by an ink-jet printer select one of 4 read-only storage modules (respectively for control characters, special characters and digits, capital letters, small letters), the remaining 5 bits being loaded, with 3 zeros, into a counter to select a word in the selected module, this word being a substitution address which is loaded into the counter to obtain a first control word from the module, the counter being successively incremented to obtain further control words from the module. Each control word contains X and Y position binary numbers which are stored and compared with X and Y counters which are incremented or decremented until equality with the respective stored numbers, the counts being converted to analogue form added to character position voltages, and used to deflect an ink jet to trace out the character. A further bit in each control word controls whether the stroke in question is printed by deflecting the jet to an ink collector plate when it is not required. Part of the substitution address is decoded and stored in a register to control bridging of stages in a clockdriven counter (or to preset the counter) so that pulses from the last stage of the counter (which are used for driving the X and Y counters) are at a selected frequency, thus controlling the printing speed. A CRT may replace the ink-jet printer (the "further bit" of each control word controlling the beam intensity).
