Title: Fluidic Binary Counters
IPC: F15C1/12
Filed: 1968-11-11
Abstract: 1,176,309. Binary counter stage. CORNING GLASS WORKS. 11 Nov., 1968 [15 Nov., 1967], No. 53226/68. Heading G4P. A bi-stable binary counter stage having a "one" output 76 and a "zero" output 80 and having its state reversed by successive input pulses 30 comprises a bi-stable wall-attachment amplifier 10 and two mono-stable amplifiers 12, 14 mutually cross coupled so as to provide a bi-stable arrangement and also coupled via restrictions 68, 74 to the bi-stable amplifier 10 so that successive input pulses are routed to the appropriate one of the two mono-stable amplifiers such that their combined state is reversed. In the reset condition of the counter state mono-stable amplifier 14 is in its stable condition supplying fluid from a continuous supply 58 firstly to the control input 40 of the other mono-stable amplifier 12, which is therefore put into its non-stable state to issue a signal on the "zero" output 80, and secondly via the restrictor 74, to the control input 24 of the bi-stable amplifier 10. The next input pulse 30 is then routed so as to reverse the states of the mono-stable amplifiers which then provide a signal at the "one" output 76. Also, feedback is applied, via restrictor 68, to the other side of the bi-stable amplifier 10, the amount of feed back being adjusted so that whilst it is sufficient to bias an input pulse 30 to one of the outputs 60, 62, it is too small to affect an established stream of fluid in amplifier 10, and thus oscillation does not take place.

Filed: 1972-11-27
Abstract: 1416338 Moulding gas diffusion electrodes GOULD Inc 27 Nov 1972 [11 Feb 1972] 54628/72 Heading B5A [Also in Division H1] A method of making a gas diffusion electrode by compression of a particulate mixture of a hydrophobic binder, catalyst, and carbon black comprises the pre-compression steps of (a) forming a slurry of the electrode forming ingredients (b) heating the slurry in an inert atmosphere to a temperature between 100‹ C. and the melting temperature of the binder, to drive off water and other unwanted ingredients, (c) grinding the mixture thus formed to produce a particulate mixture suitable for compression and (d) fluidizing the particles and distributing them uniformly over a surface ready for compressing. The Figure shows apparatus for fluidizing and distributing the particulate mixture on to a conveyer 15 by means of which the mixture may be passed between compression rollers 45, 46, and comprises a hopper 11 from which the mixture is fed on to a conveyer belt 12 for metering the mixture on to a shaker bed 13 having screens 31, 32, and a fluidized bed 14 for dispersing the mixture received from the shaker bed on to the conveyer 15, via a weir 40 and shoot 41. A collector screen 47 may be pressed into the electrode during its formation, and is preferably of nickel. In one example, a slurry of p.t.f.e., silver nitrate and carbon black is heated at 260‹ C. for one hour before grinding, after which it is compressed with a 40 mesh nickel screen to give an air electrode of 0À019 inch. In a second example, a mixture of carbon black, polypropylene and manganese nitrate is heated at 100‹ C. for one hour before grinding and compression. Electrodes other than air electrodes may be produced by varying the ingredients, e.g. a hydrogen electrode may be produced by using chloroplastinic acid in place of either the silver nitrate or manganese nitrate in the above examples.

Abstract: 1375554 Testing coins AUTELCA AG 30 Nov 1971 [4 Dec 1970] 55631/71 Heading G4V In a coin tester wherein coins 1 to be tested enter the field coil 2 of the tuned circuit of a feedback oscillator, whereupon depending on the electromagnetic properties of the coin the oscillations do or do not stop, the oscillator amplifier 4 has a negative feedback, the ratio of negative to positive feedback being variable between two values at which an acceptable coin will respectively stop and not stop the oscillations, such that if an acceptable coin is indicated at one ratio then the coin is tested at the other ratio, an acceptance signal for the coin only being issued when the tests at both ratios are satisfied. In the embodiment described the first test is performed at the feedback ratio at which an acceptable coin causes the oscillation to stop (Fig. 2, not shown) which condition is sensed by Schmitt trigger 6 and integrator circuit 7 connected via impedance transformer 8 to control circuit 9. On receiving a signal indicating that the oscillations have been stopped control circuit 9 emits a signal e to change the negative feedback ratio to the value at which an acceptable coin will not stop the oscillations, and if a signal d indicating such is received emits an acceptance signal f on line 92. If however the oscillations are stopped at the second feedback ratio, or are not stopped at the first ratio, a reject signal is emitted on line 93. A circuit diagram of the tester is shown in Fig. 4 (not reproduced). In the rest condition the supply voltage to the tester is reduced and is increased by means responsive to the insertion of a coin. Before the actual test the negative feedback can be set to a third level to determine whether an object to be tested is located in the field coil. Multidenominational tester.-A pretest device for thickness and diameter of inserted coins may be provided, this test determining a suitable pair of feedback ratios for the particular denomination of coin. Cleaning apparatus.-Detectors may be provided at the coin inlet and coin outlet, these being connected to a circuit which causes temporary widening of the coin channel if a signal from the inlet detector is not followed within a predetermined time by a signal from the outlet detector.
