Title: Skid control system
IPC: B60T8/172
Filed: 1967-09-25
Abstract: 1,206,153. Hydraulic braking systems. GOODYEAR TIRE & RUBBER CO. 25 Sept., 1967 [9 Nov., 1966], No. 43448/67. Heading F2F. [Also in Divisions G1 an H3] In an hydraulic braking system, skidding or wheel lock is prevented by a circuit which senses the wheel speed and releases the brake pressure if the speed is below a predetermined value. The system is applied to an aircraft, and comprises a transducer 10 which produces an electrical signal proportional to wheel speed. This signal is fed to a skid detector 26, which produces an output when the wheel speed falls to zero, and to a locked-wheel detector 28 which produces an output for wheel speeds below a predetermined value. This latter circuit may be inhibited by means of a switch 32. The outputs of the two detectors are fed via an amplifier 36 to actuate a valve in the braking system. The skid detector output is also fed to a circuit 34 which ensures that, after release, the brakes are applied at a lower pressure. Circuit details.-The skid detector, Fig. 2, comprises a bridge circuit with D.C. source 38 connected across one pair of diagonals, and transistor Q24 connected across the other pair. Temperature compensating diodes CR41. . . CR44 are provided in the bridge. Any sudden change in wheel speed, due to skidding is fed via capacitor C15 to point B, and unbalances the bridge sufficiently to switch on transistors Q24, Q25, Thus producing an output signal which is fed to an amplifier, Fig. 3. The amplifier output is maintained constant by a feedback path containing temperature compensating diodes CR63 . . . CR66, and is fed to a valve control solenoid. A further output from the circuit of Fig. 2 is fed to the circuit of Fig. 4 which ensures that the valve control signal is reduced after skidding. This control signal is normally determined by the voltage across capacitor C19. In the event of a skid, transistor Q20 conducts for the duration of the skid to allow capacitor C18 to commence charging. The potential to which it charges is then fed via transistor Q29 to modify the charge on capacitor C19. A further path via capacitor C17, diode CR59 and resistor R70 is also provided to modify the control signal in the event of short duration skids.

Abstract: 1447619 Exploration/mine-hunting craft FRANCE ARMED FORCES MINISTER OF 20 Sept 1972 [21 Sept 1971] 43633/72 Heading B7A A submarine vehicle, in particular a robot for the destruction of mines, includes a self-contained energy source, drive and manoeurving means, a device for making environmental observations, and electrical connecting means for connection, via a data transmission cable, to a control station whereby control data can be transmitted between the control station and the vehicle. The main body 1 bounded by a fairing 2 has attached to it on either side a fairing (5) (Figs. 2 and 3 not shown) housing a propulsion unit and is surmounted by a cable stowing compartment 9 accommodating a reel 10 on which is wound the data transmission cable 12. The control station to which the cable 12 is connected is installed ashore or aboard a ship. The fairing 2 houses an electrical storage battery 18, a projector 19 for enabling the vehicle to be located at night, and a t.v. camera 20 associated with a course repeater 21. Projectors for the camera 20 are provided in the forward sections of the fairings (5). A compartment 24 attached to the fairing 2 through a releasable device 25, e.g. explosive bolts, contains an explosive charge 28 provided with a firing device 29. Firing control wires 30 are connected via a cable 32 and connector 31 to the control station through the cable 12. A guide rope 35 formed of a string of heavy weights threaded on a cable (Fig. 4, not shown) is attached to the fairing 2 through a cable 36 itself releasably attached to the fairing 2 by an attachment fitted with a shear section allowing the cable 36 to be cut-off when required. The guide rope 35 rests on the sea bed 38 and serves to trim the height of the vehicle above the sea bed. Movement of the vehicle is controlled by command signals transmitted by the control station, the course being changed when the two motors are driven in opposite directions. If a suspicious object is located and the suspicions not confirmed, the vehicle is recovered by release of the guide rope 35 causing the vehicle's floating characteristics to become positive and the vehicle to break surface permitting an easy recovery. If, however, the suspicions are confirmed, command signals are transmitted to the vehicle to initiate the charge 28, usually fitted with a time delay device, and to release the compartment 24. The latter operation allows the body 1 to break surface and be recovered. Once the time delay has elapsed, the charge 28 explodes destroying the suspicious object concerned. While the vehicle is described as being equipped with an explosive charge for military requirements, it may alternatively be fitted with working tools for fulfilling other tasks.

Title: Variable convergent-divergent jet propulsion nozzle
IPC: F02K1/12
Filed: 1972-09-21
Abstract: 1363174 Variable area jet propulsion nozzles GENERAL MOTORS CORP 21 Sept 1972 [1 Oct 1971] 43806/72 Heading F1J The invention relates to a variable convergentdivergent jet propulsion nozzle, the nozzle assembly comprising a set of convergent flaps 24 and a set of divergent flaps 32, the divergent flaps being pivotally connected to the convergent flaps at 31. The nozzle comprises a jet pipe 2 comprising an outer wall 3 and an inner wall 4, also a nozzle support ring 8. A ring member 15 is supported for axial movement by means of pairs of rollers 16 each pair of which engages within a channel section track 19 secured to the support ring 8. The ring member 15 is movable in a downstream direction (so as to move the flap members 24, 32 to the minimum area position shown in chain-dotted lines Fig.1) by means of actuators 22 which are pivotally mounted to fixed structure at 23. The convergent flap members 24 are pivotally connected at their upstream ends 26 to the ring member 15. The divergent flap members 32 are pivotally connected to the convergent members at the downstream ends of the latter at 31. Cam members 39 are pivotally connected to the divergent flap members at 38, each cam member being formed with pairs of cam grooves 42 which are engaged by rollers 43 carried by a member 44, each carrier member being secured to a rod member 46 which is pivotally mounted at its upstream end 48 to fixed structure. Thus as the convergent flaps together with the divergent flaps pivotally connected thereto at 31 are moved in a downstream direction by means of the actuators 22 acting on the ring member 15, the divergent flaps and so the downstream ends of the convergent flaps are caused to move inwardly to the position indicated by chain-lines in Fig. 1. The flap members move outwardly by the gaspressure within the nozzle when the actuators are retracted. The nozzle assembly comprises also a number of fairing flaps 50 each of which is secured to a box-section portion 35 of a divergent flap 32 by flanges 51. The forward end of each fairing flap 50 is received within the fixed annular fairing 12 being guided by means of rollers 52 engaging in tracks 54.

Title: Nondestructively analysing biological cells using opto- electrical apparatus

Filed: 1974-10-16
Abstract: 1476793 Blood cell analyzer COULTER ELECTRONICS Inc 16 Oct 1974 [23 Oct 1973]  44773/74 Heading G1A Apparatus for analyzing biological cells comprises means for illuminating at least part of each cell with light which includes at least light in a first narrow waverange, means for detecting discretely the amount of light in said narrow waverange from each cell part after absorption thereby, and means connected to it for generating a tag signal indicating the fixed location of each cell for which said amount of light is above or below a threshold value. In the embodiment of Fig. 1, light, including that of wavelength 415 nm, from flying spot scanner 12, is directed to slide 16 with a biological cell sample. Filter 20 passes light of approximately 415 nm and reflects the rest. Filter 30 passes only yellow and reflects blue. Thus photocells 22, 32 and 40 detect 415 nm, yellow and blue light respectively and photo-cell 47 provides a source average brightness signal causing on lead 54 a voltage as both a control for variable gain amplifiers 38 and 46 to compensate for brightness fluctuation and a threshold for comparator 28. If the signal from amplifier 26 falls below this, amplifier 56 receives a tag signal and gives an inhibit signal to cause electronic switches 58 and 60 to couple a voltage representative of background from potentiometer 62 to their outputs, to which they otherwise couple the outputs from amplifiers 38 and 46. Thus the images of red blood cells, which absorb light of 415 nm, are eliminated from the video processor. In the embodiment of Fig. 2 pulsed broadband light from source 66, passes through filter 68, transmitting a narrow band around 415 nm, and the slide 70 to Vidicon 74, controlled by circuitry 78. Comparator 82 gives a tag signal, when the signal from amplifier 80 is below that from potentiometer 84, to memory 86, which also stores XY co-ordinates at that instant. Motor 87 removes filter 68 substituting another and causes switch 88 to connect amplifier 80 via analogue to digital converter 90, which is optional, to gate 94, from which video processor 98 thus receives signals except at those XY co-ordinates for which it is inhibited by a tag signal on line 96. Processor 98 can store information. If reticulocytes are differentiated from erythrocytes using a supravital stain and a filter 106 passing 530 nm is used, density analysis computer 100, activitated by the tag signal on line 104, can produce density/number histograms to determine the percentage of reticulocytes in red blood cells.
