Title: Method of measuring liquid levels in ships tanks - utilises sound waves reflected from surface to piezoelectric detector
IPC: G01F23/296
Filed: 1974-09-12
Abstract: The level of liquid in a tanker ships is measured without any contact, thus permitting a greater measure of safety. One tank (1) in a tanker is partly filled with liquid cargo (3). A sound pulse generator (7) in a control post (6) is common to a number of tanks and sends sound signals (22) via a mechanical conductor (12) to a transmitter (8) mounted in an opening (5) in the deck (4). These sound signals are reflected (23) by the liquid (10) towards a receiver (9) comprising a piezoelectric crystal. The received signals are passed along a screened copper wire (13) to an electronic processing unit (14). The electrical and mechanical conductors are placed in a steel tube (15) filled with nitrogen.

Two of the pipes are positioned on one side of a vertical line passing through the middle of the spreader, and the other two on the other side. When operating, the cylindrical hollow distributors are closed at the top, and open at the bottom. The inflow pipe is fitted tangentially to the top of the distributor. The fan conducts an air current into the housing and from there into the ducts connected to it. The fertiliser is conveyed by the air current in the distributor around its axis, so that it falls downwards in a helical movement.

Title: Calculator of variations in count rate - compares the count rates of a direct and of a delayed digital counter
Inventor: LANGLAIS JACQUES
IPC: G06F7/62
Filed: 1974-11-25
Abstract: For every event detected by the transducer (11) a digital counter (13) is incremented by one. A shift register delay (15) driven at a constant rate by the clock (17) ensures that a fixed time later a second digital counter (19) is incremented by one. The contents of the two counters are continually compared by means of a subtraction unit (21). The result of the subtraction is passed to a read-out display (25). The small oscillations are integrated by a sub-counter (19) to form a monotonously increasing function, the value of which is passed forward to the subtraction unit (21).

Title: Pneumatic grape harvesting machine - has vacuum unit with discontinuous suction produced by blanking device and delivery to container using air lock and blower
IPC: A01D46/00
Filed: 1974-12-16
Abstract: The vacuum produced by the vacuum unit (1) through air filter (3) in receptacle (2), results in a high degree of suction in narrow ducts (8, 11) and at nozzles (12) producing very efficient gathering of the grapes. This efficiency is augmented by valves which transmit suction alternately first to one and then to the other of the gathering nozzles. A blanking device (9) in the distributor produces a discontinuous suction, increasing the gathering efficiency still further. Damage to the grapes from the high suction is prevented by an expansion chamber (14). The grapes being conveyed to a container by means of an airlock and blower.

Title: Steel-and-concrete-floor sheet-metal profile unit - I-sectioned with narrow top flange and stem twice bottom flange's thickness
IPC: E04C3/04
Filed: 1975-04-29
Abstract: The shaped-section unit, of the type produced by cold-forming processes, is designed for incorporation in floors made of sheet steel (or other metal) and concrete, such units being laid together and subsequently covered in concrete, and needing to withstand considerable loading and tension. It is I-shaped in cross section, with the top flange narrower than the bottom one, and both the top flange and the interconnecting stem are twice as thick as the bottom flange; this may be achieved by making the top flange and stem from two layers of sheet metal side by side, the ones in the top flange being welded or mill-edged together, and the ones in the stem being interconnected by half-punched-out tongues. There may be longitudinal creases in the flanges, and the bottom flange may have a downwards-open central longitudinal groove. A better utilisation of the elastic qualities of the sheet steel is attained.

Title: Magnetic core for three-phase transformer has equilateral triangle - whose sides are formed by laminated frame member joined at corners (NL090476)
IPC: H01F27/24
Filed: 1975-05-28
Abstract: The magnetic core, for a 3-phase transformer, has three vertical columns connected at their upper and lower ends by magnetic yokes. Three frame members (12) form an equilateral triangle and are constructed from continuous, wound laminae (13). Each frame member has a smooth surface (14) at the corners of the triangle so that when the core (11) is assembled these members lie at angles of 120 deg. relative to one another.

Title: Nitrogen oxides removal from oxygen-contg. gas mixts.
Inventor: NISHIKAWA EIICHIROH
IPC: B01J23/652
Filed: 1975-09-19
Abstract: Nitrogen oxides are removed from an O2-contg. gas mixt. by introducing into the mixt. 0.1-20 mole of a reducing agent per mole of nitrogen oxides and passing the mixt. over an Ir (or Ir cpd.) catalyst deposited on a carrier (pref. alumina) at 200-450 degrees C.
