Desirably the units of the electronic timing system comprise plug-in modules enabling the control units for various speed settings to be controlled from a central processor.
Patent GB-2029016-A (GB)
Title: Vertical seismic exploration and profiling technique
IPC: G01V1/42
Filed: 1979-07-18
Abstract: In a vertical seismic exploration technique, periodic signals are emitted to propagate seismic waves in subsurface earth formations penetrated by a borehole. Seismic waves in formations near the bore hole are received at determined borehole depths and their representations recorded to form a vertical seismic profile. Exploration is conducted by recording representations of seismic waves at borehole depths varying by depth intervals ( DELTA X, Fig. 1B, not shown) corresponding to a time interval  DELTA t dependent upon the wave period of a given mode. Profiling is accomplished by selecting recordings from borehole depths separated by this depth interval and combining using time delays related to the wave period and the propagation direction of the mode to produce traces E preferentially suppressing seismic waves propagating in one direction (1), (2) while automatically reinforcing those propagating in an opposite direction (3), (4). A vertical seismic profile is recorded, which may also utilize this time interval between traces. Use of depth and time intervals respectively approximating one- quarter of the wave length in the formation near the borehole and one- quarter of the recorded wave period of a selected propagation mode simplifies field production of the directionally preferential suppression and reinforcement characteristics of the resulting vertical seismic profile. <IMAGE>

Filed: 1979-07-23
Abstract: A mobile folding stage having a pair of stage surface members (10, 11), main support legs interconnected to form a base frame (12), and outer support legs (14, 15). Casters (70-73) are connected to caster beams (60-63) which are pivotally mounted to a caster frame (45) secured to the main support legs. Actuator links (86, 87) connect from the caster beams to the stage surface members to cause extension of the casters when the stage is brought to its horizontal, operable position, and to retract the casters when the stage is folded to its storage position. Outer leg control links (120) are positioned with respect to the outer leg to provide an over center resistance force which holds the stage surface members in their folded position. In the preferred embodiment, elevational adjustment is achieved through auxiliary support legs (130, 131), and the caster beams (60, 61) are shaped and positioned, together with stop members (141, 142) to position and secure the auxiliary legs in their fully extended position. <IMAGE>
Patent GB-2031615-A (GB)
Title: Improvements in or relating to hydraulic control systems for variable displacement hydraulic pumps
IPC: F04B49/08
Filed: 1979-08-03
Abstract: A variable displacement hydraulic pump 2 supplies hydraulic working fluid to the hydraulic swing motor 1 of an excavator and has a control system in which a double-acting hydraulic cylinder 23 controls a swash plate via a selector valve 17 and a second double- acting hydraulic cylinder 18. Fluid pressure is selectively applied to opposite ends of the cylinder 23 via hydraulic fluid supply lines 27, 28 connected to manual controls of the excavator. Relief valves 35, 36 connect opposite sides of fed, the pump to opposite ends of the cylinder 23, each relief valve connecting its associated side of the pump to the opposite end of the cylinder to which fluid pressure is applied in order to select that side as the pump output. Each valve 35, 36 opens in response to excess output pressure to apply fluid pressure to said opposite end of the cylinder so as to resist further movement of its piston 24 and, hence, reduce movement of the swash plate in the selected direction. In this way, acceleration of the swing operation is controlled. Moreover, when the dipper of the excavator is held against an obstruction, the system controls the pump output so that the pump only supplies the minimum fluid required to replenish internal leakages in the system. <IMAGE>
Patent GB-2035006-A (GB)
Title: Method and apparatus for measuring the speed of a moving object
IPC: G01S13/60
Filed: 1979-10-01
Abstract: The speed of moving objects is measured using the Doppler Radar principle. A mixer M receives the reflected radiation from the beams St1, St2 delivered by the antenna (A) and generates a Doppler signal (ds) having a velocity dependent frequency. An evaluation circuit DA produces from the Doppler signal (ds), a signal (vgr) which is applied to an autocorrelation circuit K to determine the timing of the autocorrelation window. The maximum time  tau max of the autocorrelation function of the Doppler signal ds when divided into the separation (distance L) of the microwave beams (St1, St2) yields a more accurate velocity measurement. <IMAGE>

Patent GB-2080746-A (GB)
Title: Independent suspension/final drive systems for vehicles
IPC: B60G3/24
Filed: 1980-07-29
Abstract: In a rear suspension/final drive system for vehicles the rear wheel axles are mounted on radius arms (mounted on torsion bars or resting on coil springs) which are pivoted to the vehicle chassis in a manner that their pivots are coaxial with the final drive outlets of the differential gear unit whereas the wheel axles are off-set and mounted at the ends of the radius arms. Fixed length drive/cardan shafts connect the differential gear outlets to the wheel axles obliquely through constant velocity universal couplings. The advantage of this arrangement is the retention by the driving wheels of their planes of rotation while moving up and down in relation to the vehicle due to springing action. This endows the vehicle with better road-holding, longitudinal and lateral stability and reduces tyre wear significantly. <IMAGE>

Title: Axial gap squirrel cage induction electric motor
IPC: H02K17/16
Filed: 1980-10-08
Abstract: The stator (21) of the motor is of annular form, with generally radial slots (22) which receive the energising windings. The squirrel cage of the rotor has a magnetic component (16) and a conductive component comprising inner ring (10) and outer ring (12) joined by bars (14). The bars (14) are curved so as to follow a path with a higher radial component at the inner end than at the outer end. This reduces perceived noise by avoiding sharp registering of the rotor bars with the stator slots, and also by providing a more uniform ratio of magnetic to conductive material in the rotor at different radii around the rotor axis. Bars (14) may be below the rotor surface (Figure 6, not shown). Geometrical parameters are specified. <IMAGE>
