Abstract: 1,022,586. Direction indicator signals on road vehicles. JOSEPH LUCAS (INDUSTRIES) Ltd. Aug. 12, 1964 [Aug. 17, 1963], No. 32609/63. Heading G4Q. A vehicle direction indicator system comprises a current relay connected to a flasher unit operating lights on the vehicle, the relay being adapted to operate lights on a trailer vehicle. The flasher unit 5 comprises a coil 8 adapted to attract an armature (not shown) to close contacts 10, the armature being restrained by a resistance wire 9 until the latter expands on being heated. When the contacts 10 close the indicator lamps 7 light, and if both lamps operate the current through coil 8 is sufficient to attract a second armature (not shown) and close contact 11 to light a pilot lamp 13. A current relay 14 is connected to the junction of wire 9 and coil 8 so that when contacts 10 close current will pass through coil 15 and through a severable connector 19 to light a lamp 16 on the trailer. The current flowing through coil 15 attracts an armature (not shown) which closes contacts 17 to illuminate a second pilot lamp 18. Units 5a and 14a are identical to the corresponding units 5 and 14, and one or other of the two sets of units can be energized from the battery through a three-way direction indicator control switch.

Title: Improvements in or relating to power transmission systems
IPC: F15B13/08
Filed: 1939-12-20
Abstract: 534,055. Hydraulic power transmission : fluid-pressure brakes. VICKERS, Inc. Dec. 20, 1939, No. 32632. Convention date, Dec. 31, 1938. [Class 69 (ii)] [Also in Group XXXIV] A hydraulic power transmission system which is especially applicable for applying selectively variable forces to brakes for vehicles or aircraft is constructed with fluid motors 98, 100 with operative pistons 102, 104, the flow of fluid to the motors being controlled by spool valves 48, 50 which selectively connect the motors to fluid pressure or exhaust. The pressure is obtained from a pump 12 which delivers through a relief valve 18, check valve 22 to an accumulator 24 and to a pipe 26. Connected to the pipe 26 is a spring-controlled piston valve 31 which operates a switch for energizing electromagnets 23, 25, which control a byepass valve 19 adapted to unload the pump when the pressure in the accumulator reaches a pre-determined value. The valves 48, 50 have a common inlet pipe 40 leading past a check valve 45 to a chamber 46. Between the accumulator and the pipe 40 is a pressurereducing valve 36 comprising a spring-controlled piston which is lowered to close a passage 34 when the pressure overcomes spring 38. The valves 48, 50 are operated by independent lever mechanism 60, 62, which control plungers 52, 54. The plungers transmit motion through springs 86 to the valve members and the extent of motion given to each plunger is much greater than that required to move the valve. The raising of valve 48 first opens up connection from chamber 46 to the cylinder 98, but as the pressure rises in the cylinder it also rises in a chamber at the top of valve 48, which is connected by a passage 92 to the pressure pipe 94a, and the valve is thus depressed to cut off the pressure from the cylinder 98. The pressure established depends on the force exerted on the piston 52. When this force is withdrawn the spring pressure on the valve is relaxed and the valve is depressed to connect the fluid pressure to the pipe 88 leading to exhaust. The valve 48 is formed with a poppet valve 56 which seals the valve from exhaust when the valve, is fully opened to pressure.

Title: NMO Correction of Digitized Seismic Signals
IPC: G06F17/17
Filed: 1967-07-17
Abstract: 1,197,931. Processing seismic signals. TEXAS INSTRUMENTS Inc. 17 July, 1967 [26 Aug., 1966], No. 32803/67. Heading H4D. Normal moveout (NMO) corrections are made on a digitized field seismic trace by means of time-domain filters which interpolate the trace amplitude values at time points located between the digital sample times, the filters being selected and successively applied in dependence on seismic wave travel time. The need for interpolation arises where the corrected trace is presented as a series of digital samples at uniform time intervals #T 0 , because the movement corrections are generally fractions of the field trace sampling interval #T. The relation between field trace time Tx and corrected trace time T v  is known from seismic velocity data and is shown in Fig. 3. For applying moveout corrections with a limited number of filters the moveout curve is approximated by linear segments and different filters are used over the different segments. In one embodiment each filter is six points in length (i.e. has six weighting coefficients) and the particular filter selected for interpolation at a time point tx n  between two field trace samples is applied to the nearest three samples on both sides of t Xn . Twenty filters are provided to allow interpolation at twenty respective time points equally spaced within the sampling interval #T; sequential selection of the particular filter and routing of the six samples to the selected filter from storage registers is controlled by gate circuits. The samples are read into the registers from a digital magnetic recording of the field trace and the corrected trace is recorded magnetically. The time domain filters may be digital or analogue (appropriate D/A and A/D converters being provided in the latter case). Instead of the above signal processing apparatus a digital computer may be used.

Title: Stacking seismic traces with time increments determined from  seismic model
IPC: G01V1/28
Filed: 1972-07-13
Abstract: 1393602 Seismic data processing MOBIL OIL CORP 13 July 1972 [24 Sept 1971] 32824/72 Heading H4D In the processing of seismic traces a digital seismic model of the subsurface layers producing the traces is first generated, the trace-to-trace moveout of reflection events is calculated from the model, and the traces are then stacked in accordance with the calculated values of moveout. By repeatedly changing the seismic model and iterating the calculation and stacking, the model which best depicts the subsurface layers can be selected on the basis that it gives the highest stacked signal power. In the Fig. 3 flow chart for the processing of common depth point (CDP) traces reflection travel times Ti, interval velocities Vi and dip #T/X are computed at 11 by a known "velocityby-integrated power" process. These values are used at 12 to generate offset versus travel time curves along which the traces are stacked to form a first seismic section. This section is migrated at 14 to give a digitized, layered model (depth section), by a known method. The processing can be monitored by converting the model to a travel time section at 15A for comparison at 15 with the first seismic section. At 16 a ray-tracing technique is used to compute from the model (knowing the source-toreceiver geometry, interval velocities and reflector co-ordinates), the trace-to-trace moveout of reflection events. For these values of moveout the traces are stacked at 17 to give a seismic section in which the reflection signal has been enhanced. The model is then changed, at 18, e.g. using an interactive graphics method, and steps 16 to 18 are iterated. The signal powers in the resulting stacked seismic sections are compared at 19 to identify the best seismic model.
