Title: Extrusion die with variable cross section profile - comprises fixed segment and rotatable profiled segment
IPC: B21C25/08
Filed: 1976-04-28
Abstract: Die comprises two die segments mounted in a bearing to form the die aperture. One segment is rigidly mounted and tghe other with a periphery forming a variable profiled surface is rotatably mounted so that the die aperture profile can be changed by rotating this segment about its axis. Used for extruding Al alloy panels with variable cross sectional profile over the length for the aircraft industry. The die design is simple and the extruded articles require less machining and are therefore cheaper. The cross-sectional profile can also be changed over a wide range.

Title: Vapour motor for use in solar heating systems - incorporating a collection and return system for fluid leaks and having sliding surfaces pref. of PTFE
IPC: F01B31/18
Filed: 1976-07-16
Abstract: The fuid circulates in a closed circuit between the solar heater, where it is vapourised, and a condenser, where it is liquefied, passing through a piston and cylinder motor where part of its thermal energy is transformed to mechanical energy to drive the pump. The surfaces of the motor which are in sliding contact are pref. made of PTFE to eliminate the necessity of lubrication. The motor cylinder is provided with a double gland packing through which the piston shaft moves, the space between teh packings forming a fluid collection chamber from which the fluid is returned to the condenser. The lubrication of the motor parts in contact with the motor fluid is avoided, so the mixing of the fluid and the lubricant which would lead to a loss in efficiency and possible motor trouble is avoided. The collection and return to the circuit of fluid eliminates the necessary for replenishing the motor fluid. This makes the motor suitable for use in areas such as semi-desert areas where constant fluid replenishing is impracticable.

Title: Telephone system tuned filter circuit - has several tuned sections each preceded by operational amplifier receiving output of adjacent section
Inventor: BOULANGER CLAUDE
IPC: H04Q1/453
Filed: 1976-12-10
Abstract: The filter circuit is designed to detect frequencies in the range 700-1700 Hertz. The circuit consists of several filter sections. Each section is tuned to a particular frequency and is preceded by an operational amplifier. For a multifrequency system fi (i = 1, 2--K..) the filter sections (2-5), which are tuned to frequencies f2-fK-1, are each preceded by an operational amplifier (10-13). In addition to the input signal each operational amplifier receives signals from the neighbouring filter sections, i.e. fi+1 and fi-1. The filter sections (1 and 6) tuned to the lowest and highest frequencies (f, and fk) are also preceded by operational amplifiers (9 and 14). The amplifiers receive, in addition to the input signal, the output signal of the neighbouring section i.e. f2 and fk-1.
Patent FR-2343171-A1 (FR)
IPC: F16H63/30
Filed: 1977-02-17
Abstract: An automatic multiratio drive transmission having an automatic shift control system with a speed and throttle position pressure controlled shift valve controlling shifts between the highest drive ratio and the next lower drive ratio. When the shift valve is in the lower drive ratio position, a normal speed pressure signal increasing with increasing speed acting on the shift valve overcomes an opposing bias force controlled by throttle pressure to upshift the shift valve to the higher drive ratio position at increasing upshift speeds for increased throttle positions and provides an upshift hysteresis force decreasing with increasing throttle positions to prevent shift cycling as the highest ratio is established in a short time period and after a longer time delay period reduces the normal speed related governor pressure in an amount equal to the upshift hysteresis force at full throttle so that the downshift speed is the same as the upshift speed at the full throttle position.

Title: Combined hydraulic dumper truck and excavator - has detachable scoop for mounting on rear of supporting tractor
IPC: E02F3/627
Filed: 1977-03-04
Abstract: The usual type of hydraulically operated combined dumper and excavator has the dumper mounted at that end of the machine which has the larger wheels.

Title: Short period interrupter for telephone circuits - has two winding relay with CR circuit controlling time of interruption
IPC: H04M1/53
Filed: 1977-07-21
Abstract: The contact interrupter for telephone circuits provides a short clear period allowing selection of complementary lines. The interrupter circuit is designed to prevent other contact switching functions to inhibit the selection switching during the interrupt period. When the touch switch (T) is operated the capacitor (C1), charged via R1, excites the winding (F1) of a two winding relay. This opens the relay contact (f). (e2) then charges via R2 until the switching voltage of the unlatching diode (D1) is reached, then C2 discharges via the second relay winding (F2). This closes the relay contact (f). The period taken determines the time of interruption, and depends directly on the values R2,e2.
