Abstract: 1,232,887. Electric car with air cushion support; motor vehicles. ELECTRIC FUEL PROPULSION Inc. 13 Feb., 1969 [16 Feb., 1968], No. 7778/69. Headings B7H and B7K. A car 18 powered by electric storage batteries 22, 24, 26, 28 is partially supported, when it is moving, by a cushion of air generated by a fan having blades 68, 70 and (69, 71), Fig. 2 (not shown), and contained by concentric cylindrical skirts 82, 83. The car is circular in shape with a window 64 and the batteries power a motor 20 which drives rear wheels 30, 32 through an axle 34 and differential 36. A ground-engaging wheel 80 drives, through a gearing system, Fig. 3 (not shown), a shaft 51 which rotates the fan blades, for example 68, 70, and this drive may be disconnected by a clutch, by raising the wheel 80 or tilting the shaft 51. Alternatively the shaft may be driven directly by the motor 20. The fan draws in air through a large number of small holes 65 which have been punched in a housing 50 and the amount of air drawn in may be regulated by a movable plate 84 which is mounted within the housing and is adapted to be rotated slightly so as to align or misalign its holes 85 with the holes 65 in the housing. Alternatively one or more plates could be used to block the flow of air from the housing 50 into the area between the skirts and this would increase the weight of the vehicle when braking. Coils of wire 88 are wound round the fan blade and a number of magnets 100, 102 are disposed about the path of the blades so that a current is induced which recharges the batteries via a commutator 108 and the control mechanism 46 when the vehicle is moving. It is stated that this invention is also applicable to internal combustion vehicles and that they may be regeneratively braked. Instead of one air cushion several small air cushions may be used to support the vehicle.

Abstract: 1,238,555. Lathes. J. E. LONERGAN CO. 29 July, 1969 [26 May, 1969], No. 37896/69. Headings B3B and B3T. In an automatic lathe in which screw cutting is to be performed means is provided for displacing the tool slide transversely to the work spindle axis and successively adjusting its position relative to the workpiece to permit successive cuts to be taken during successive traversing movements of the tool and slide. A slide 34 is supported on a slide block 33 attached to a turret 23. The block 33 has secured thereto an adjustable feed stop 58 and an adjustable cam 61 which controls the indexing movement of a rotary stop carrier 77. The carrier 77 has adjustable stop rods 78 radially spaced thereon and which are engageable with the feed stop 58, in succession, at each pass of the cutting tool during a screw-cutting operation. The slide 34 is biased by a spring 39 to urge the respective stop rod 78 against the feed stop 58. Following a cutting traverse of the cutting tool the slide 34 is acted upon by a pusher member 38 on a cross slide 37 to displace the slide transversely to clear the cutting tool from the work during its return traverse, the pusher action being against the bias of the spring 39. A dashpot device 41 on the slide block 33 and attached to the slide 34 permits a slow return movement of the slide 34 as the slide block is traversed back to its initial position with the turret. The displacement of the slide by the pusher 38 also causes the engagement between the cam 61 and roller 88 on a plunger 83 on the slide 34 which actuates and pin-wheel 76 and pawl 82 mechanism to effect indexing of the stop carrier 77 ready for the subsequent cutting pass of the cutting tool 35. In an alternative embodiment, Fig. 6 (not shown), the cam co-operates with a plunger to effect the indexing of the stop carrier, and is provided with an oblique rear face and is pivotable transversely to the slide to permit the return movement of the slide without actuating the plunger, the indexing in this embodiment occurring at the forward limit position of the slide 34 instead of during the rearward return stroke as in the first described embodiment.

Abstract: 1,250,100. Antiskid braking systems. GOODYEAR TIRE & RUBBER CO. 15 April, 1969 [22 May, 1968], No. 19126/69. Heading F2F. An anti-skid braking system for an aircraft includes a modulator circuit which discharges more rapidly after the first anti-skid cycle than it discharges throughout the remainder of the landing run so that the braking pressure is not held unnecessarily low during the first few seconds after touchdown when the vertical loading is relatively low. A rotatable wheel 10 has an exciter ring 12 to actuate a transducer 14 which generates an alternating signal which is converted to D.C. and sent to a skid detector 18. The output from detector 18 can be sent directly to an amplifier 20 or selectively through a modulator 22 to the amplifier, the output of which is sent to a valve 24 connected to a pressure source 26 so that the signal from the amplifier controls the brake pressure to apply a pressure just short of that which will cause a skid. The modulator circuit comprises a capacitor 30 charged by an input signal from the skid detector 18 and having its discharge rate established by resistors 40, 42 and an added circuit 50 temporarily provides an additional discharge path via diode 60 and resistor 62 into a grounded capacitor 64. A resistor 66 is of comparatively high value so that capacitor 64 cannot quickly discharge thus resisting rapid discharge of capacitor 30 in later cycles.

In the automatic liquid treating, e.g. dyeing, of at least two batches of material contained in separate baths the following operations are successively carried out for each bath in an order and at periods independently set for each bath, the stages of each operation being fixed with a' predetermined time-lag between them; (a) feeding water into the bath to a predetermined level; (b) feeding from a main vessel predetermined quantities of the desired main treating liquid and washing liquid containing any main treating liquid remaining in the vessel into the bath; (c) feeding to the vessel a predetermined quantity of the desired auxiliary treating liquid from a vessel, one of which is provided for each different auxiliary liquid; (d) circulating the resulting mixed liquid through the material and; (e) discharging the liquid from the bath. Apparatus comprising the above components together with the necessary pumps, valves and conduits which are programmed to effect the process above is claimed per se. The following features are preferred: (1) for ensuring slow delivery of the auxiliary liquid to each bath the liquid is, in its turn, pumped rapidly from the auxiliary vessel to a second vessel having a small bore outlet through which the liquid trickles under gravity to the bath; (2) compensation may be made for slow liquid take-up by materials which would cause level-indicating devices to give false readings; (3) automatic ventilation valves may be provided to avoid pressure changes inside closed vessels during filling and emptying and; (4) to prevent frothing of liquids, circulation through the material may only take place when the liquid level is high enough. The programme may operate electrically via control relays. The circulation of liquids radially through material wound on a hollow support is described.

Abstract: 1295941 Control of DC motors SINGER CO 14 Jan 1970 [21 Jan 1969] 1771/70 Heading H2J A D.C. motor is energized from an A.C. supply via a drive S.C.R. and is dynamically braked by connecting it to a dissipative load via a brake S.C.R., and means are provided for preventing simultaneous conduction of both S.C.R.'s comprising means for delaying operation of the brake S.C.R. for a predetermined time after the termination of a stop command signal, and a monostable device responsive to triggering of the brake S.C.R. inhibits triggering of the drive S.C.R. When treadle T is in its relaxed position, motor 10 is energized through S.C.R. network 31 since trigger-line 32 is connected through resistor 33 to voltage-line 26. Capacitor 38 is short-circuited through contact 41 whereby brake trigger-line 42 is not energized, a monostable multivibrator 46 being in its stable state so that switching transistor 35 is cut-off. To stop the motor, the treadle is moved and switch 30 engages contact 53. The line 26 is earthed to remove voltage from trigger-line 32, the S.C.R.'s 14 remaining conductive until the end of the respective half-cycles of power voltage. To prevent premature firing of the brake S.C.R. 45, the voltage on trigger line 42 is increased at a rate determined by the charging of capacitor 38 through resistor 39. When diode D breaks down, S.C.R. 45 is triggered to connect braking resistor 44 across armature 11. The time-delay is chosen to be longer than the maximum time for the S.C.R. network 31 to turn off. The S.C.R. 45 is rendered non-conductive when the back EMF of the motor reaches a low value. To prevent the S.C.R. network 31 from being turned on, even though commanded to do so, before the brake S.C.R. 45 has turned off the trigger pulse from the threshold diode D is also applied through diode 52 to the multivibrator 46 which changes state to render the transistor 35 conductive. This earths the line 32 and inhibits triggering of the S.C.R. 31 for a pre-set period. Resistor 33 and capacitor 34 prevent the sudden application of full voltage to the line 32, so protecting the S.C.R. 31. The voltage on line 26 is increased in steps by operating switches 27, 28, 29, in sequence under the control of the treadle.
