Title: Balanced high press. hydraulic valve - rotation of captive end cap produces axial actuation via screw thread
IPC: F16K39/02
Filed: 1973-05-24
Abstract: A hydraulic valve for use in very high pressure systems. The valve itself is formed by the conical end of the actuating shaft and a correspondingly shaped seat.

Title: Fuel economiser for aircraft jet engine - adds hydrogen and oxygen from decomposition of water to engine fuel
IPC: F23R3/40
Filed: 1974-01-23
Abstract: The economiser consists essentially of a cylindrical tube which has an internal corrugated surface (4) of platinum or tungsten. The cylinder and internal surface are heated electrically by a current passed directly through them between electric leads (2, 3). The cylinder also contains a rotor (6). Water vapour enters radially through a tube (1) and is projected against the heated corrugated internal sides by the rotor (6) and the resulting thermal excitation causes it to decompose into oxygen and hydrogen which pass through a selectively permeable membrane (5) and leave the cylinder through a radial discharge tube (7) from which they are added to the main engine fuel.

Title: Cable junction covering sleeve - has epoxide resin filling metal-coated insulating two-part sleeve with gap
IPC: H02G15/105
Filed: 1974-03-04
Abstract: The sleeve, forming a cable junction box housing, consists of an insulating housing constructed in two halves (2, 3) and has a gap (6) left between the halves along one side. The outside of the sleeve is covered in a metal layer (5), and two conductors (7) run along the edges of the gap between the halves. The space around the joined cables inside the sleeve is filled with epoxide resin introduced through the gap. The conductors along the edges are connected to the earthed metal ends (4) of te sleeve and serve to eliminate edge effects around the gap, where the metal screening is discontinuous, and thus reduce the maximum electric field strength. The edge conductors can also act as earthing lines for short circuit currents.

Title: Pickling meat prods. with brine in rotary vacuum drum mixer - without prior injection of brine or surface scarifying during mixing
IPC: A23B4/32
Filed: 1975-10-31
Abstract: The prod. is first perforated deeply with a number of holes made by the insertion of narrow cutting blades. Mixing is then carried out in the presence of brine without using any axially displacable agitator independent of the mixing vessel and without using any surface scarifiers during the mixing operation.

One end of the vessel has an aperture with a removable lid which is secured to and sealed to the rim of the aperture by atmos. pressure while a vacuum is maintained in the vessel throughout the mixing stage. Ther is no need for prior injection with brine. A greater quantity of brine can be diffused into the tissues than previously. The quantity of brine can be closely controlled. Vacuum can be 'broken' several times during processing to induce diffusion of brine into the tissues.
Patent FR-2331024-A1 (FR)
Title: Detection of chemical pollution in water - by studying effect on rainbow trout in a vortex
Inventor: LESEL RENE
IPC: G01N33/18
Filed: 1975-11-04
Abstract: Detection in water of chemical pollution, which is (sub-) lethal to fish, is effected in a circular current of water in a funnel; a vortex is created by the tangential feed of the liq by the pump. The funnel is connected to the reservoir and to the pump. A probe is connected by the cable to a timing clock and to the pump. The degree of pollution is indicated by its effect on a living fish, such as a rainbow trout. Normally the level of the liq. remains constant but when the fish swimming in the vortex can no longer struggle against the current it blocks the outlet and the water rises till it touches the probe; this stops both the clock and the pump. The period of time that the fish can resist the suction effect of the vortex is a measure of the toxicity of the liq. The test can be used for the detection of chemically pure toxic substances in water and also for the evaluation of the toxicity of complex mixts., such as effluents discharged into natural waters. Synergistic effects can be studied and the overall toxicity of a raw effluent to fish can be determined.

The filter comprises two sections, one of which removes the grease and the second the odours associated with cooking. The filters are able to be used individually or together depending on the position of a changeover handle.

Title: Fibreboard mfg process - has structured pressure redn programme for evapn. of water in wet fibre feed material (SW210676)
Inventor: HULLEN ALFRED VAN
IPC: D21J1/04
Filed: 1975-11-25
Abstract: Wet fibres are inserted into a heated press where heat and pressure remove the water and compress the fibres into a board. For the evapn. stage, the pressure is reduced to 50% of the max. pressure to be used until there is a residual humidity of 8-10% in the material. The pressure is then slowly decreased while the fibre material is compressed to the required density and thickness, to give a residual humidity of 6-8%. The system reduces the amt. of press time required for the mfr. of fibreboard, and the finished material has a humidity level which eliminates the need for elimination.
