Title: Humidifier for air supply to engine or burner - is filter with porous body partly immersed in water
IPC: F23L7/00
Filed: 1975-05-05
Abstract: A device for saturating the air supply to an internal combustion engine or an oil burner consists of a filter which also cleans the air as it is humidified. This action is carried out without mechanical, electrical or electronic assistance. The air supply is first preheated, and in the case of a vehicle engine, the vehicle heating system may be used.

Title: Reel holder for unwinding station in cable twisting machine - has two displaceable rotary centres, one being braked
Inventor: BERTHOUX PIERRE
IPC: B65H49/26
Filed: 1975-05-16
Abstract: A reel carrier for supporting a heavy coil of wire or a rope strand in a cabling machine, has two rotating centres facing each other along a horizontal axis; the one being perfectly free to rotate whilst the other is slowed down in its rotation by a brake fitted at the end of its shaft. Each of the centres is mounted on a thrust bearing supported by a jack cylinder; the rams of which move along a horizontal path coinciding with the axis joining the tips of the two rotary centres. Design eliminates the pushing action causing the flanges to slide along the ground when only one centre is extendable, and provides a simple and cheap carrier for the reel.

Title: Gramophone record feed system - has records stacked between protective plates with four posts holding plate edges and controlling lowering onto turntable
IPC: G11B17/18
Filed: 1976-07-19

Title: Hide stacking device for tanneries - with photocell control of stacking table carriage motion
IPC: B65H29/18
Filed: 1976-09-10
Abstract: A device for stacking hides in tanneries between operations in a certain order includes a transfer belt conveyor, consisting of many narrow individual belts with photocells in some of the gaps which can be masked by the passing hides.

Title: Photoelectric oil emulsion check probe - has transparent fingers for lamp and photocell coaxial to fluid flow
Inventor: HOGH MICHAEL SOMERLED
IPC: G01N21/53
Filed: 1976-09-24
Abstract: A probe to check the oil content of oil-in-water emulsions for use in oil tankers before the ballast can be discharged into the open sea, measures the optical light transmission capacity of the mixt. passing through a cell. Both the light source and the photoelectric cell are accommodated inside transparent fingers or are linked to them by fibre optical light guides. This reduces errors introduced by diffused light as well as by contamination of observation windows. The probe is easy to dismantle and to assemble. The high velocities create turbulence which automatically keeps the cell clean.

Title: Preliminary ultrafiltration of milk for soft cheeses - with short drainage period to obtain final controlled pH desired
IPC: A01J25/11
Filed: 1977-01-24
Abstract: When making soft cheeses, the curds and/or the milk used in obtaining the curds are given a preliminary treatment in order to get a consistent prod. with an increased dry extract of 12-18% at a pH of 4.8-5.1; the resultant whey is sepd. and the curds drained for a sufficiently short time to obtain a final controlled pH and a cheese-making paste of good physical soundness.
