Title: Submerged seaweed cutting machine - has roating and reciprocating cutters following zig-zag path
IPC: A01D44/00
Filed: 1974-07-03
Abstract: The device is supported by a cable fixed to the end of an hydraulic crane, mounted on a boat. The device consists of reciprocating cutter bars which cut the sea-weed at the bases of the stems, and which are driven by a submersible motor through pinions. The cutter bars rotate around the motor. A boom integral with the cutter bars releases compressed air which raises the cut out leaves above the cutter into a hood integral with the motor support. The hood is composed of a frame covered with a net and leads into a duct also of similar construction, and supported by floating rings. Additional compressed air outlets can be provided along the duct. An endless conveyor picks up the weed from the upper end of the duct and loads it into the boat.

Title: Differentially loaded shotgun cartridge - has varying arrangement of pellets to vary area of scatter
IPC: F42B7/04
Filed: 1974-09-12
Abstract: A cartridge for a shotgun can be filled with pellets in different ways, so that the user of the gun which is designed to fire only one size and shape of cartridge, can select the type of cartridge required to suit the type of game being hunted. Thus the pellets can be arranged to scatter over a larger area or to be concentrated onto a smaller area. Two weights or pellets can be used and the larger pellets can be arranged at the front with the smaller pellets at the rear, or vice versa or a third degree can be obtained by mixing the two sized indiscriminately. In the first case, the heavier pellets at the front give higher speed and greater impact force, giving maximum scatter.

Title: Electronic control for automatic transmission - modulates hydraulic servo pressure against rate of change of input shaft speed
Inventor: HILL WILLIAM FRANK
IPC: F16H61/00
Filed: 1975-06-23
Abstract: The automatic transmission has a hydraulic torque converter driving an epicyclic gear box operated by friction brakes. The friction brakes are operated w.r.t. hydraulic pressure from a pump driven by the engine and w.r.t. road speed of the vehicle. In order to obtain smooth gear changes the hydraulic pressure has to be regulated during gear change, so that the friction brakes can be gradually applied. The rate of change of input shaft speed of the gear box is monitored and regulates the manner in which the hydraulic pressure is modulated during gear change.

Title: Static measuring instrument - measures power or work in AC network using voltage by current multiplier
Inventor: VRIES JACOB DE
IPC: G01R21/127
Filed: 1976-04-09
Abstract: A wattmeter forms a product of network a.c. voltage and network a.c. current. It has at least one magnetic core, to whose first winding the a.c. current is applied, or d.c. voltage through a resistor. Its second winding so controls the multiplier mark/space modulator, that it delivers a pulse voltage in which the ratio of the difference to the sum of pulse width and pulse spacing is proportional to the instantaneous value of the network a.c. current or voltage. An oscillator has a frequency much higher than the network frequency. It saturates the magnetic core whose second winding is connected through a differentiating element to a threshold switch generating the pulse voltage.

Title: Error compensation in sync. detector amplifier - alternatively switches signal to be detected between filtering and amplifying circuits
Inventor: BONNEFOY-CLAUDET JEAN-PAUL
IPC: H03D1/22
Filed: 1976-08-13
Abstract: The synchronous detector error compensation method sends alternatively the signal to be detected into two amplifying and filter circuits. The signal is sent to the two circuits via two gates which are controlled in phase opposition by a synchronising signal. At a frequency f1 the connection between the two amplification circuits is switched with the outputs of each of the two gates. Also at the frequency f1 the connection of the outputs of the two amplification circuits if switched with an output terminal. At this terminal can be observed the continuous synchronous detected signal resulting from the difference of the signals routed via the two gates. At the frequency f1 the correction of the gate controls are transposed by the synchronising signal and the outputs of the two gates connected to the inputs of the filtering and amplifying circuits.

Title: Solar heat collector circulating a refrigerant - which can be used all year and which builds neatly into roof
IPC: F24S10/50
Filed: 1976-08-17
Abstract: A device, esp. for heating water by solar energy has a conduit for circulating a fluid, one wall of which absorbs the heated of the sun. The fluid circulated through the conduit, is the refrigerant R12. The conduits with a blackened wall surface forms part of a condenser circuit, the condenser coil being placed inside a balloon or similar vessel contg. the water to be heated. There is a compressor between the conduit and the exchanger, and a detenter between the exchanger and the conduit. The action of the detenter is adjustable by the fluid leaving the evaporator. Between the evaporator outlet and the detenter there is a pressure equalising channel. There is a bypass of the compressor controlled by a valve, as well as a bypass of the detenter, similarly controlled, in which a pump is fitted. Unlike conventional solar panels, the device can be used all the year round, and is not unslightly when fitted on a roof. The refrigerant keeps the conduit wall temp. sufficiently low to prevent losses by convection or by radiation.
