Abstract: 1318720 Counting particles CORNELL AERONAUTICAL LABORATORY Inc 13 Nov 1970 [18 Nov 1969] 54127/70 Heading G4D [Also in Division G1] Liquid-borne particles are detected by passing them through a light beam which then passes through a diffraction grating 44. A sample of blood and diluent is driven by an impeller 12 through a flattened micro-capillary tube 33 past a light beam. The beam passes through a diffraction grating 44 to cast an image on a plane 46, a small part of which includes a photodetector 48. The output 49 is compared with that 51 of a background detector and sent to a signal analyzer 52. Depending on the characteristics, Fig. 5, of five types of white cell, red cells, and platelets, so signals appear on one or more of three leads 56, 58, 60, to mark one of leads 64-76 to register on an appropriate counter. At the same time a sorter 78 is operated (Fig. 7, not shown) to collect the detected particle.

An arrangement for measuring the strength of a magnetic field, which may be that due to a direct current, comprises a saturable core exposed to the magnetic field and a transistor switching circuit operative to connect energizing turns 13 on the core to a supply voltage to saturate the core in one sense and thereupon to reverse the connection of the supply voltage to the energizing turns to saturate the core in the opposite sense, and a milliammeter 14 to measure the average current flowing in the energizing turns 13 as an indication of the field strength or the magnitude of said direct current, as the case may be. The energizing turns 13 may be split into two equal parts, with an output resistor connected between them, Fig. 3 (not shown), connected to a long-tailed pair transistor amplifier (18, 19), whereby push-pull signals may be derived from the collectors of the transistors (18, 19) at terminals (20, 21). Transistors (18, 19) may be of NPN or PNP type. Any unbalance in the characteristics of the transistors in the switching circuit may be corrected by a potentiometer (22). For measuring ambient field strength, the saturable core is preferably rod-shaped, Figs.4a 4b (not shown), and may have end pieces to define an H-shaped magnetic structure, the energizing turns being grouped near the centre of the rod.

When an obstruction is encountered the support 84 is pivoted about the pin 83 which has the non-tangential axis. The spring can be omitted if the working centrifugal forces are sufficient to urge the surfaces together.

Abstract: 1455437 Line circuits CONTROL NETWORKS CORP 6 Dec 1973 [21 June 1973] 56539/73 Heading H4K In a multi-stage switching network having a plurality of line circuits 11 associated with respective input conductors of the first stage, marking current for the line circuits is provided by a constant current source 51 common to a plurality of line circuits. To mark a particular input conductor 24 a negative pulse is applied to the base of Q3, thereby rendering this transistor conductive. The output of the constant current source is accordingly connected to the conductor and if there is a free crosspoint associated with the conductor it will be fired. Transistor Q1 indicates the state of conductor 24. If a path has been established through the network, the conductor will be positive and Q1 will be switched OFF. And vice versa. Transistor Q2 indicates the on-or-off-hook condition of the subscriber set associated with conductor 24. When the set is off-hook, the R and T leads, 56 and 57, are connected together and hence the positive bias at the base of Q5 is removed. This transistor therefore conducts, causing Q2 to conduct. Conversely, in the onhook condition Q2 is turned OFF. The crosspoint switching element may be SCRs.
