Title: Seismic hydrophone signal processor - has charge coupled amplifier which suppresses stray signal pick up and stray capacity fluctuations
IPC: H03F3/45
Filed: 1975-06-12
Abstract: The seismic signal system is used for the detection of signals in the form of acoustic pressure waves, which are sensed by a capacitive sensor and fed via an unearthed twisted pair cable to a signal processing unit. The output is connected to a differential amplifier of charge coupled type by which the variable electrical charge at the transducer output is converted to an output voltage. The amplifier includes a stage in the form of an operational amplifier with the output fed back to the inverting input through a feedback chain containing a resistance and condenser in parallel so that the output signal is independent of variations in the stray shunt capacity across the input.

Title: Clock displaying vehicle parking times - synchronises auxiliary display when driver's door is opened using hinge operated switch
IPC: G07C1/30
Filed: 1976-08-25
Abstract: A specialized clock and auxiliary display for displaying the parked time of a vehicle synchronizes the otherwise stationary auxiliary display to that of the clock whenever the driver's door is opened. A clock has a display (14) on one end of a rectangular prism shaped box (10) which carries the auxiliary, normally stationary clock display (18) on its top surface so that it is visible from outside the vehicle. This auxiliary display is driven by an electric motor via a gear chain and friction coupling.

Title: Caisson placing on submerged foundation - using temporary plastics bearing strip taking part load and forming bays receiving concrete
Inventor: DELAUZUN JULIEN
IPC: E02D23/08
Filed: 1977-04-06
Abstract: The construction process entails the placement of a caisson (1) on a prepared submerged foundation (2) and may be deployed in Civil Engineering works e.g. the installation of foundations to bridge piers. The base (10) of the caisson (1) is initially placed on a deformable self-sealing strip bearing (21, 32) delineating a series of rectangular bays, and the bay volumes are then filled with e.g. concrete (61). The process obtains uniform bearing pressures beneath the caisson on roughly levelled formations. The strip bearings (31, 32) may be placed on the formation and comprise bitumen impregnated sand, or may comprise inflatable tubes fixed to the base of the caisson. When the sand/bitumen bearings are used, double sealing skirts (13) may be provided on the base (10) of the caisson. During the first phase of the installation part only of the loads from the caisson are transmitted to the temporary bearings (31, 32), with the full load being allowed to act after the bays have been filled. Lateral displacement of the caisson may be prevented by previously installed piles (5).
