Abstract: 1442989 Reciprocating conveyers DAVEYLOEWY Ltd 21 Sept 1973 [10 Oct 1972] 46638/72 Heading B8A [Also in Division B3] Conveying apparatus, for moving rolled beams 3A, 3B from a cooling bank 1 to a roller table 4, includes a number of independent carriages 6 each of which is movable along a track 5, Fig. 4, and which can be raised or lowered. Each carriage supports a carrier 8 on which a horizontal shoe 10 and a vertical plate 9 are carried. The shoe is adjustable relative to the plate 9 using holes 13. To shift a beam, the carriages are moved by pulley-driven cables to the left until the plates 9 engage the beam. The tracks 5 are then raised to lift the shoes beneath the beam, and the carriages are moved to positions above the roller table. Lowering of the tracks causes the beam to be deposited on the table. To accommodate the carriages to curved or distorted beams, each carrier 8 is slidable relative to the carrier 6. After a shifting operation, all the carriers are realigned by moving them against a right-hand stop 15. Alternatively, the carriers may be fixed in the carriages and slipping clutches in the driving system may be employed.

Title: Electric generators
IPC: G01P15/00
Filed: 1970-10-01
Abstract: 1306699 Controlling differential locks ROBERT BOSCH GmbH 1 Oct 1970 [2 Oct 1969 (2)] 46654/70 Heading B7H [Also in Divisions F2, G1 and H2] A generator for use in a system for measuring acceleration of a vehicle wheel comprises a discshaped rotor 27 located adjacent three coils 32, 36, 38 wound on the parallel arms 31, 35, 37 of an E-shaped magnetic core 28. The rotor shaft 26 is coupled to the vehicle wheel and the magnetic circuit is completed by a stationary yoke 29 mounted opposite the arms of the core on the other side of the rotor. As shown in Fig. 2 the coil 32 is connected via a constant current device 33 to a D.C. source 34, so that a constant magnetic field is produced in the core. Eddy currents produced in the disc 27 by rotation thereof produce a further magnetic field which is superimposed on the first one. Changes in the superimposed field caused by acceleration or deceleration of the disc produce voltages in the coils 36, 38 which are oppositely wound and connected in series so that the voltages are added together. The output is amplified at 39 and the resulting signal may be passed to the control circuit of a vehicle braking system. Fig. 3 shows a modification in which the centre coil 32 is energized from an A.C. signal generator 136 through a transformer 134. The A.C. field produced in the core 28 induces voltages in the coils 45, 46 which are oppositely wound so that no net voltage results. The superimposed field produced by rotation of the disc generates voltages in coils 45, 46 which are added together and passed through a rectifier bridge 143. The resulting pulsating D.C. signal is filtered at 154, 155 and differentiated at 156, 157 to produce an output at 158 proportional to acceleration of the disc 27. Another application referred to is detecting wheel slip in rail or road vehicles. In the latter case the output signal may actuate locking mechanisn for a differential gear when one wheel slips. Alternatively the output may be connected to an indicator for measuring the efficiency of vehicle brakes.

Title: Traffic responsive speed control system
IPC: G01S13/931
Filed: 1971-10-12
Abstract: 1344146 Automatic speed and position control BENDIX CORP 12 Oct 1971 [4 Nov 1970] 47402/71 Heading G3R In a vehicle having an automatic speed control system, upon approaching a lead vehicle, the system is over-riden and the spacing between the vehicles controlled to a value determined from the lead vehicle speed, the actual spacing and the rate of change of spacing, under all conditions the speed of the vehicle being limited to a driver selected value. In an embodiment, when a vehicle 16, having a conventional automatic speed control 11, approaches a slower lead vehicle, an adaptive speed control 12 maintains the vehicle at the speed of the lead vehicle and at a safe following distance dependent on the leading vehicle speed. A sensor system 22 e.g. a Doppler radar, optical or microwave transmitter determines the range R and range rate R of the leading vehicle from a signal reflected from that vehicle. A signal processor 23 which receives the range and range rate signals from the sensor system 22, and a trailing vehicle speed signal V 2  from a speedometer 17, calculates, and sends, either a throttle error signal E to the accelerator control 14 if the relative velocities between the vehicles is low and can be corrected by the accelerator, or a brake error signal E b  to brake control 24 if the trailing vehicle is travelling faster than the lead vehicle and is within the safe following distance. In either case, the desired speed  V 2  set by the driver for the automatic speed control 11 can only be exceeded by manual control of the vehicle i.e. when the adaptive speed control 12 is overriden, for example to overtake. The mathematical equations for E and Eb are given, these signals being derived from the R, R & V 2  signals by circuits as in Figs.3 to 5 (not shown). When cornering, the sensor system which may ignore signals from a range of over 300 feet, rejects erroneous signals reflected from fixed roadside objects. To avoid hunting when the cars are travelling at the same speed and at the safe following distance i.e. zero signals from the sensor system 22, a capacitor memory controls the vehicle from the last R and E signals for a pre-selected time, after which a small acceleration signal accelerates the vehicle and the sensor system resumes control. As the required speed and range is approached, the braking or acceleration signals may be removed, allowing the vehicle to coast to the required speed or position.
