Abstract: 1,032,821. Anti-skid brakes. P. W. BOTHWELL, and W. B. BARTON. Dec. 14, 1962 [Jan. 2, 1962], No. 103/62. Heading F2E. [Also in Division B7] An anti-skid brake arrangement for a road vehicle, e.g. a motor-cycle, in which the brake is applied through a lever, comprises an alternator formed by a plurality of permanent magnets secured to a ring rotating with the wheel to be braked, a pick-up coil or coils positioned adjacent the ring of magnets so that alternating current is generated in them, and means sensitive to the voltage and/or frequency of the generated current to cause current to be fed to a device acting on the lever to reduce its mechanical advantage whenever the rate of change of the voltage and/or frequency exceeds a predetermined value. As shown, a hub 1 is mounted for rotation on a spindle 2 secured to the front forks 3 of a motor-cycle and is formed as a drum enclosing a conventional internal shoe drum brake mechanism actuated through a lever 13 and cable 15. The lever 13 consists of a tube carrying a lug 16 for attachment to the brake spindle and a solenoid 17 (Fig. 3, not shown) which, upon energization, moves an armature 18 within the tube against the action of a spring 19 to cause a cable attachment bracket 14 secured to the armature to move towards the lug 16 so reducing the mechanical advantage of the lever. Current is fed to the solenoid whenever deceleration of the wheel exceeds a predetermined value, by a generator comprising a ring 9 of nylon secured to the hub 1 and to which are attached permanent magnets presenting alternate north and south poles for movement, on rotation of the wheel, past pick-up coils 12. The resultant generated current in the coils 12 is fed to a rectifier 21 (Fig. 6, not shown) across the output of which is a load resistor 24 and, in parallel with the latter, a relay 23 in series with a condenser 22. When the rate of change of voltage on the condenser is sufficiently high, contacts 25 close to complete a circuit from a battery 26 to the solenoid of the lever 13, i.e. when the rate of change of voltage produced in the coils 12 exceeds a predetermined value.

Patent GB-1529501-A (GB)
Title: Blooming control for charge coupled imager
IPC: H04N5/372
Filed: 1976-01-05
Abstract: 1529501 Image sensing arrays RCA CORPORATION 5 Jan 1976 [13 Jan 1975] 00206/76 Heading H4F [Also in Division H1] In a method of controlling blooming in a charge coupled image sensing array having electrodes capacitively coupled to a substrate some of the electrodes are held, during an integration period, at such a potential that depletion regions are created in the substrate. During the same period other electrodes are held at such a potential that accumulation regions are created between the depletion regions. Following the integration period, and for a period which is short relative to the integration period, the potentials are changed so that those regions formerly in accumulation are driven into depletion and those formerly in depletion are driven further into depletion; this operation has the effect of reducing loss of resolution on read-out. Subsequently multi-phase voltages are applied to the electrodes in order to shift any stored charge along the substrate, e.g. to a register. The period during which shifting takes place corresponds to the vertical fly-back period of a television raster scan.

Filed: 1948-01-07
Abstract: 632,007. Phase changing. GENERAL ELECTRIC CO., Ltd., and BRYDEN, J. E. Jan. 7, 1948, No. 529. [Class 38 (ii)] A potentiometer used as a phaseshifting device comprises a number of series-connected impedance elements fed from A.C. supply and a contact slider arm mounted at the centre of the potentiometer on a shaft 9 driven by a shaft 15 through a mechanism by which a more linear relationship is obtained between the phase of the output voltage and the movement of the shaft 15 than if the slider arm were driven directly. In the latter case the error in phase is approximately equal to -1.12 sin 6# degrees for a six-phase supply, where # is the angular displacement of the driving shaft, but if the above mechanism is used this error is reduced to about Œ 8 minutes. The mechanism comprises an arm 18 having one end fixed to the driving shaft 15. At the other end of this arm, a gear-wheel 19 is arranged to rotate in engagement with teeth 12 in a cylindrical moulding 11. An eccentric pin 20 on the gear-wheel 19 slides in a slot in an arm 22 fixed to the shaft 9 carrying the potentiometer slider. Due to the pin 20, the slider arm will be advanced and retarded progressively in relation to the shaft 15. The gear ratio corresponds with the number of phases of the supply source, being six for the 6-phase example described. The impedance element may be resistive or inductive.

Abstract: 588,191. Vehicle steering mechanism. BURMAN & SONS, Ltd., and BRIGGS, W. H. Jan. 9, 1945, No. 783. [Class 80 (iii)] In order to minimise the effect of forces transmitted from the road wheels to the steering spindle b, Fig. 1, of a vehicle, the spindle is provided with a fixed collar f coacting with floating friction rings g splined to frusto-conical locking rings h formed with interengaging wedge like teeth i, Fig. 2. The rings h cooperate with corresponding surfaces formed on the housing c. In action, the endwise pressure exerted on the spindle through the usual slidable nut and screw a of the steering mechanism moves the collar f into engagement with one or other of the friction rings so as to effect rotation of the corresponding ring h and, through the teeth i, the other ring, thus producing axial displacement of the rings and frictional resistance between the housing and the rings to the rotation of the spindle. In a modification, the driver's spindle b is separate from the screw a and connected thereto by a quick pitch screw thread.
