Title: Analog to digital converter
IPC: G11C11/44
Filed: 1959-04-13
Abstract: 861,282. Electric selective signalling systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 13, 1959 [April 11, 1958], No. 12416/59. Class 40 (1). [Also in Group XXXVI] An analogue to digital converter comprises a closed loop of material capable of exhibiting super conductivity, said loop including a hard super conductor 4, Fig. 1, and a soft super conductor 6, magnetic field producing input means 16 inductively coupled to said hard super conductor and output means 12 arranged to give an indication upon each change of state of said soft super conductor. When certain materials are cooled to very low temperatures (e.g. by immersion in liquid helium) they become super conductive, that is their electrical resistance becomes substantially zero. If a magnetic field of sufficient magnitude is applied to a super conductor it becomes normally conductive (that is its normal resistance returns). Some substances such as bismuth-lead eutectic require a large magnetic field before this occurs and are referred to as " hard " super conductors whereas others, such as lead-indium alloy, require a relatively low field and are referred to as " soft " super conductors. In the circuit described, if a varying current, Fig. 2, is passed through input coil 16, for each incremental change in the current by an amount Ic an output pulse OA, OB, &c. is said to be produced in coil 12 and applied to an amplifier 14. The Specification contains a statement as to the principle by which the circuit is thought to function. Specification 861,280 is referred to.

Abstract: 1,089,166. Liquid dispensing apparatus. AMERICAN NATIONAL VALVE CORPORATION. March 22, 1966, No. 12642/66. Heading A4T. [Also in Division F2] A valve 10 for dispensing a predetermined quantity of liquid comprises an inlet 19 leading to an outlet 35 via a passage 25. containing a butterfly valve 28, the outlet leading to a valved dispensing nozzle (not shown). When the nozzle is opened, liquid flows through valve 10 and the pressure upstream of the butterfly valve acts on a piston 22 to move the latter away from an adjustable stop 73 and towards the stem 40 of a valve member 37, liquid in advance of the piston being expelled via an orifice 58 adjustably throttled by a screw (66) (Fig. 2,. not shown). The piston 22 eventually abuts stem; 40 and then moves member 37 to cause a closure surface 39, 42 on the latter to stop flow through outlet 35. The pressure now builds up in outlet chamber 32 and maintains members 37 in its rightward position and opens a check valve 62 to equalise the pressure across piston 22 to allow spring 24 to return the piston into engagement with stop 73. When the dispensing nozzle is closed, the pressure across closure surface 39, 42 is equalised via passage 42a and the valve is unseated by spring 44. In the embodiment shown, the stop 73 is formed at the end of a rod 70 carrying an arm 77 that may be positioned in one of a number of recesses in a plate 80 according to the quantity of liquid that is required to be dispensed. Adjustment of the quantity dispensed is achieved by means of stop 73, butterfly valve 28 and variable orifice 58. In an alternative embodiment, the rod 70 is threaded into the valve housing. A magnetic filter may be installed in valve 10.
