Abstract: 1,215,587. Demonstration unit. UNELCO Ltd. 7 Dec., 1967 [12 May, 1967], No. 55675/67. Heading G5G. [Also in Division H2] A unit for use in demonstrating or testing the characteristics of a device having a rotor, e.g. a motor or a generator, comprises a casing including a top wall having an aperture therein, and an apertured base wall or an open base, and aligning means for locating the unit relative to other units when similar units are stacked one upon another; a device, having a rotor, within the casing; and coupling means exposed through the aperture in the top wall and through the apertured base wall or open base, the coupling means being arranged so that when the unit is stacked with similar units with the aligning means of the stacked units engaged the coupling means of the units can engage. As illustrated the device is an electrical device 30 housed within casing 10. The coupling means comprises a friction wheel 32B connected to rotor shaft 31. Alternatively the coupling means may comprise a gear (32) (Fig. 2 , not shown). Each casing includes projecting feet 22 and apertures in the top wall for receiving the feet of a similar unit when the units are stacked. Collars 22A, which may be integral with the feet or separate washers, space the adjacent base and top wall of stacked units. When two units are stacked the friction wheels engage. Thus where the devices are a motor and a generator, the motor will drive the generator. A transparent front wall 14, comprises two panels 14B, 14C with terminals 18A, 18B and may include a diagrammatic illustration between the panels or on the rear face of the wall, of the circuitry of the device. In use the terminals are connected to other apparatus which demonstrate the characteristics of the devices. The casings are further provided with combined hand holes and ventilating apertures (21A) (Fig. 1, not shown). An alternative embodiment in which the coupling means is the rotor shaft is illustrated in Fig. 4. Coupling of the shafts of two stacked units may be accomplished by a triangular spigot 31B on the shaft of one unit, engaging with a sleeve e.g. of rubber or plastics having a similar recess in the other unit, or by a pin (33), (Fig. 10, not shown), non-circular in section, which may be received in shaped apertures in the shafts of the two stacked units.

Abstract: 1343759 Selective signalling NORTHERN ILLINOIS GAS CO 10 Dec 1970 [10 Dec 1969] 58769/70 Heading G4H In a system for obtaining data from a plurality of remote stations, a central station interrogates a remote station which sends coded data to the central station using a locked oscillator tuned to the frequency of the interrogation signal. As disclosed, a meter reading van transmits by ratio to meter locations a 29-bit signal, each bit being represented by one of two tone frequencies amplitude-modulated on to a carrier 28 of the bits form 7 decimal digits each in 8421 coded form, to identify a meter. At a meter location, the tones are detected to produce bit pulses which are shifted into a 29-bit shift register, each detected tone also producing a clock pulse to drive the shift register and switch on the local power supply. Code recognition gates respond to the bits, and if they identify this meter, four decimal digits, each in 2-out-of-5 form representing the meter reading (except the units, tens and hundreds), are gated into the shift register to replace the 5 highest orders of the meter-identifying digits, and power is supplied to a quenching modulator and locked oscillator. The van sends a series of 29 ones and the clock pulses from these shift out the shift register to control the quenching modulator to supply one of two frequencies for each bit to the locked oscillator to produce one of two sets of (frequency-shifted) sideband signals on the carrier from the van, these signals being detected in the van with the data being decoded and printed together with the meter identity originally specified in the van.
