Title: Improvements in or relating to Analogue to Digital Converters
Inventor: DIXON JOHN GORDON
IPC: H03M1/00
Filed: 1966-06-27
Abstract: 1,190,754. Measuring angular displacements. MUIRHEAD Ltd. 25 May, 1967 [27 June, 1966], No. 28769/66. Heading G4H. In an analogue-to-digital converter of the type in which the angular position of a coarse resolver shaft (Fig. 1) (connected via gearing to a fine resolver) is digitized by converting the outputs of the resolvers into impulses, the frequency of which is proportional to the angular position of the resolver shaft, the least significant decade of a counter counting the impulses from the coarse resolver is made to agree with the highest digit of a counter associated with the fine resolver. In the embodiment described in which for rotation of the first resolver shaft from 0 to 180 degrees the digital count increases from zero whilst for continued rotation from 180 to 360 degrees the digital read-out decreases to zero, a logic circuit is included in the encoder to mask off the first two pulses reaching the coarse counter so that any error in the counter is between 0 and - 4 degrees. A gate 1 (Fig. 2) gives an enabling signal if the fine units counter stores 0, 1, 2 or 3. Gates 3 and 4 give an enabling if the coarse units counter reads 6, 7, 8 or 9 so that a further gate provides a pulse to increase the coarse tens counter by one digit. For example, if the coarse counter stores 137 degrees and the most significant digit, that is the units digit in the fine counter, is one indicating that the correct count is 141 degrees a one is added to the coarse tens counter and the unit digit is read from the fine counter. Logic circuitry (Fig. 3, not shown) is used to give an indication of whether the shaft is in the sector 0 to 180 degrees or 180 to 360 degrees by setting a bi-stable device to its 0 or 1 state respectively.

Filed: 1939-11-01
Abstract: 536,257. Gaseous density. ROBINSON, T. W. S. Nov. 1, 1939, No. 29112. [Class 97 (iii)] To measure the density of a gas or gas mixture the gas and a comparison gas are caused to flow simultaneously through a pair of orifices at predetermined rates and thereby set up a differential condition which can be measured. Fig. 1 shows a container a, b, c, d having orifices g, h and an inner bell i vertically movable therein. A liquid seal is introduced through an aperture an overflow n being provided to limit the quantity of liquid and a drain duct x is also provided. The gas mixture to be tested is introduced into the lower chamber through duct k at a rate greater than it escapes through orifice h causing the bell i to rise to a pre-determined height as shown by an indicator p through a window q. The gas mixture is then shut off and the bell i falls by gravity causing the comparison gas, i.e. air, to flow into the upper chamber through the orifice g thereby setting up a differential pressure at the inner and outer parts of the orifice g which may be measured by means of a duct z leading to a pressure meter. A modification is described in the Specification.

Abstract: 819,409. Closuring bottles. DATZ, H. Sept. 25, 1957, No. 30028/57. Class 125(2). Relates to machines for applying swing bail stoppers 22 to bottles 9 in which the bottles are first rotated to bring the stoppers into desired position in which they are maintained by claws 21, the stoppers are then raised by devices 36 on to the bottle necks, and then finally the bails are pressed down to lock them by devices 51, the bottles being carried through the stages by a horizontal endless conveyer chain 3 provided with bottle grippers 4 clamped on to the bottle at the appropriate times by a fixed cam. According to the invention a plurality (three as shown) of each of claws 21 and devices 36, 51 are mounted on axles 11 in drums 8, the drums are rotated about horizontal axes by the engagement of forks 5 with arms 6 also on axles 11, there being one fork on the conveyer 3 for each gripper 4, and the claws 21 and devices 36, 51 are maintained vertical for correct engagement with the bottle or stopper as the drums rotate by epicyclic gear trains 13, 14, 15 within the drums. In the first stage the bottles are rotated as they move by friction with a rail 12 and, if the stopper 22 be out of position, it lifts a member 19 to maintain claw 21 raised, the member 19 and claw 21 dropping when the stopper is correctly positioned, the claw engaging in the bail to prevent further rotation. The grippers 4 then close, and, in the second stage, the bail is first lifted part way by a fixed rail 29, a further part by a lever (not shown), and then into engagement with a top rail 39 by a pin 35 on device 36. The device 36 is rotated (to rotate pin 35) when it runs on a fixed rail (not shown) when it reaches the lowest point of its rotation with its drum 8. Rail 39 turns the stopper on the bail so that its upper surface is uppermost and the stopper then enters a slot in guide rail 40 which suspends it until it drops into the bottle mouth at the end of rail 40. In the final stage, devices 51 descend to lock the bails.
