IPC: G01N15/14
Filed: 1975-11-25
Abstract: 1505763 Simultaneous scanning at two resolutions J E GREEN 25 Nov 1975 [25 Nov 1974] 48447/75 Heading G1A Apparatus for scene analysis comprises means for searching at a low resolution including means for detecting when an object of interest is encountered and for initiating means for analyzing it at a higher resolution while the low resolution searching means continues to search. Sample carrier 1 has blood sample 4 with cells of interest 5a, 5b, 5c. Via beam splitter 6b areas 7 and 11 are imaged on to low resolution sensor 9 and high resolution sensor 13 respectively. These are TV cameras, image dissectors or photodiode arrays. When an object of interest is encountered, drive motors 2 and 3 move carrier 1 to bring the object into the field of view of sensor 13. In the embodiment of Fig. 4 (not shown), carrier (1(b)) is fixed and the fields of view are moved by two plane mirrors preceding the first lens (as 6 in Fig. 1) and rotatable by two motors with their shafts at right angles. The sample may be stationary with respect to one or both of the scanning fields of view while high resolution scanning is occurring.

[Also in Division G3] A valve for a vehicle power steering system comprises two passages between a pressure fluid inlet- 16 and an outlet 12 to a reservoir 22, each passage containing an inlet orifice 48 or 50, an outlet orifice 56 or 58 and between the orifices a port 66 or 68 leading to a working cylinder and a flapper valve 38 which simultaneously restricts the inlet orifice of one passage through a plunger 90 or 92 and the outlet orifice of the other passage while increasing the openings of the other two orifices when rotated to move the piston 26 in the working cylinder. In the embodiment a steering shaft 34, which has the flapper valve 38 formed thereon, is connected, by a torsion bar 40, to a rotary valve member 44 with annuli 46, 74, 76 and passages interconnecting the inlet, outlets and orifices. Resilient pads 83, 84 on the flapper valve and the plungers 90, 92, maintained in contact with the flapper valve by the fluid pressure on their ends 91, 93, coact with the orifice openings and, should the pressure fluid supply fail, contact the openings to provide a direct connection between the steering shaft 36 and output member 42 to maintain steering control. The degree of " feel " is determined by the dimensions of the torsion bar 40 and the relative diameters of the orifices and the neutral position of the valve is adjustable by rotation of the threaded orifices in the valve member 44.

Abstract: 1332924 Measuring acoustic velocity DR J & H KRAUTKRAMER GES FUR ELEKTROPHYSIK 26 Oct 1970 [24 Oct 1969] 5068/70 Heading H4D In an arrangement for measuring acoustic velocity in a sample of material, the sample 4 (Fig. 1) is immersed in a tank of water 1 and using the pulse-echo technique the echo (Fig. 2) from the top surface 4a is displayed on a cathoderay tube 9 in alignment with the zero of scale 11 calibrated in terms of acoustic velocity, the time base speed then being adjusted to bring the echo 7 from the bottom surface 4b into alignment with the scale mark Cf corresponding to the acoustic velocity of water and the acoustic velocity in the sample (steel) then being read directly in the scale at the position of the bottom echo 8 when the sample is removed from the tank. In an alternative operational arrangement a marker 12 produced by a pulse which is adjustable (in time) in relation to the initial pulse 5 is first aligned with the bottom echo 8 (sample absent), the sample is then immersed in the tank and the echoes 6 and 7 aligned (as in the previous arrangement) with the zero and Cf scale marks respectively and the acoustic velocity in the sample is then read on the scale against the marker 12. In a further arrangement a computer is employed to divide the transit time between echo 6 and marker 12 by the transit time between echoes 6 and 7 and then divide the quotient by the acoustic velocity of water, Cf, the result, the acoustic velocity Cm in the sample being indicated or printed. By employing the first reflection to start the time base the echo 6 may be automatically aligned with the zero of the scale.

Abstract: 1327400 Automatic control systems SIEMENS A G 2 Nov 1970 [15 Nov 1969]  52084/70 Heading G3R A control system comprises a controller having two input paths receiving an error signal in one of which is an integrator 12 preceded by a limiter 9 and in the other is a derivative-action device 10. The limiter substantially prevents temporary disturbances from affecting the integrator output. The arrangement is applied to apparatus for winding a fibre in which fibre tension is kept constant. Variations in tension are detected by a weighted pulley 3 connected to a potentiometer 7 whose output is normally zero, but changes in tension produce a positive or negative error voltage which is applied to the system of the invention. The integrator output is made unidirectional by limiting it to zero with respect to one polarity, and is applied to an inverting amplifier 14 which produces an amplified negative signal when a positive signal is applied. It comprises two transistors, Fig.3 (not shown), and is biased by -ei so that its output decreases from a maximum value. The signals are compared at a summing junction 11 with the output of a tachogenerator 17 and the resultant forms the desired value for a motor current control loop 16, 19, 20 whose output controls the triggering of a regulator 22 in the motor circuit. Mention is made of the control of a plurality of motors, with a single control potentiometer to adjust all their maximum speeds. Controller 16 has a proportional plus integral action.
