IPC: C07C7/11
Filed: 1974-03-13
Abstract: Acid gases, esp. H2S and CO2, are sepd. from gaseous hydrocarbons by (a) treating the hydrocarbons with a lean aq. amine soln. to remove the acid gases, forming a rich amine soln. contg. also is not 4C unsatd. hydrocarbons, (b) treating the rich amine soln. in a 1st stripping zone, in countercurrent with a non-condensible low-mole gas, as stripping agent, (c) removing the non-condensible gas the is not 4C unsatd. hydrocarbons from the rich aq. amine soln., and (d) passing this rich amine soln. to the regeneration zone. Removal of the unsatd. hydrocarbons avoid polymerisation in the regeneration zone, to prevent fouling. The gaseous hydrocarbons are esp. pyrolysis cracking prods.

Title: Manual onion peeling appts. - with adjustable cutting blades
IPC: A23N15/08
Filed: 1974-06-21
Abstract: Manual onion peeling appts. which can be operated without affecting the eyes, consists of a frame resting on three elastic blocks. A holder carries blades arranged in the form of a 'V'; the angle between the blades can be adjusted at will. The operator holds the onion in the hand with the little finger resting on the frame; as it is moved horizontally the swellings due to the roots and the stalk are removed. The onion is then placed on the two wheels, the cone-shaped edges to form a cradle, and brought up against an incising blade mounted in a holder which is adjustable according to the size of the onion. Two wheels, on each side of the blade, can be moved to control the depth of the incision; the onion rests on these wheels while being rotated by hand around an imaginary axis perpendicular to the blade. Peeling is effected rapidly; the external skin of the onion can be divided into two distinct parts without causing irritation of the eyes.

Title: Control valve for ion thruster - has electrical heating element in sealed chamber of volatile liq. adjacent diaphragm connected to operating stem
Inventor: LABBE JEAN
IPC: G05D23/19
Filed: 1975-09-17
Abstract: Operation of the valve depends upon electrical heating by a resistive element (53) of a sealed chamber (39) fitted with a diaphragm wall (29) and containing a small amount of volatile liquid e.g. benzene. When heated the liquid vapourises and the increased pressure forces out the diaphragm and opens the valve (15) by means of a shaft (22). The opening of the valve is resisted by a set of spring washers (14) acting on the valve head and contained in another chamber (11). This chamber is also heated by windings (51,52) and the whole valve is enclosed in a thermally insulated (55) container (56,57,58). In operation, the windings of the second chamber are supplied with current to maintain the assembly at a temp. just short of the vapourisation temp. of the benzene.

Title: Two speed drive for supercharger of diesel engine - uses starter motor to drive supercharger on starting engine
Inventor: ECOMARD ANDRE
IPC: F02N19/00
Filed: 1976-03-22
Abstract: The super-charger of a diesel engine is normally driven by a V belt which drives a pulley mounted on a bearing in the supercharger housing. The pulley is provided with internal teeth which engage matching teeth on a sleeve. To start the Diesel engine, the pinion, of the starter motor is pushed forwards to engage the teeth of the flywheel at the same time the teeth of the sleeve are pushed out of engagement with the teeth of the pulley and a tongue engages a slot. The supercharger is then driven by a starter motor at a much higher speed so that engine starting is made easier.

Title: Connector between ski and harness - has base plate to carry harness having fixing slots and held on adjustable guide rails
IPC: A63C9/00
Filed: 1977-01-28
Abstract: Ski harness fitting plate enables adjusting position of harness. The fitting plate consists of a base plate (1), onto which the harness grips (8a, 8b) are fixed. The base plate (1) is held on guide rails (2) fixed to the ski upper surface. By the provision of slots in the base plate (1) for fixing the harness parts, the distance between the toe grip (8a) and heel grip (8b) can be adjusted to allow for a large number of shoe sizes. The skiers centre of gravity can be moved along the ski by sliding the base plate (1) carrying the harness along the ski on the guide rails (2). The height of the plate can also be adjusted along one or both sides by altering the guide rails (2). This method provides a ski harness fitting which can be adjusted as required for any skiers requirements and allows the type of harness to be changed without the need for making extra screw holes which can weaken the ski.

Title: Glass panes sepd. by wax blobs for shipment - where blobs also make the glass visible after its installation
Inventor: FAUST HANS
IPC: B65G49/06
Filed: 1977-03-08
Abstract: The surface of a glass is provided with separate blobs of hard paraffin with m.pt. >50 degrees C or wax with m.pt. >85 degrees C. Each square metre of glass pref. has 4-100 blobs, each with height 0.2-2mm. and dia. 2-20mm. The blobs are pref. applied in a molten state, and possess high shrinkage so they do not strongly adhere to the panes. The blobs separate stacks of panes during their transport, and thus eliminate the need to interleave the panes with paper. When the panes are installed, e.g. in a building, the blobs are easy to see so workers know the pane is in place, thus avoiding damage; and the paraffin or wax is easy removed by the mechanical pressure of hot water.
Patent FR-2383498-A1 (FR)
Title: Cassette tape recorder control - with mechanical and electrical modes simultaneously selected by common pushbutton
IPC: G11B15/10
Filed: 1977-03-10
Abstract: The mode selection mechanism is for use with a tape recording machine which employs cassette cartridges (14) loaded with magnetic tape (12). The mechanism is controlled by a number of pushbuttons (18) to (28). With each button is associated a mobile mechanism which moves between operative and inoperative positions when the respective button is activated. In addition to the mechanisms associated with each button is a respective circuit mode control which is energised by the same button activation. Thus selection of an operative mode of the recorder involves simultaneous mechanical and electrical switching by a common control.

Title: Sliding clasp fasteners mfr. from toothed tapes - by removing teeth at required location and fitting end pieces
IPC: A44B19/58
Filed: 1977-03-18
Abstract: Two long lengths of pre-toothed tape are made into several fasteners by removing a number of teeth at appropriate places to allow the start- and end-pieces of the individual fasteners to be fitted to the tape, which is then cut across. Number of teeth removed between fasteners is always the same, whatever the lengths of the finished fasteners, and the required start- and end-pieces are added in a single operation, pref. injection moulding. The tape moves forward through the mould under the control of a sensor which counts teeth as they pass.

Title: Opaque internal structure imaging - using ultrasonic probe with switched transmitters on curved surface and convergence point aperture (NL 31.10.78)
Inventor: BRIDOUX EDOUARD
IPC: G01N29/26
Filed: 1977-04-29
Abstract: A device producing images of internal opaque structures uses ultrasonic waves. It enables continuous visible display of heterogeneous body sections contg. discontinuities which are able to move. In an medical application it minimises the cross-section of the body covered by the ultrasound whilst achieving customary power levels. The ultrasonic probe has oscillators arranged in a row or pattern as a curved surface. By switching electronically between oscillators an angular range is covered and ultrasonic wave beams are generated which converge in a defined region. A screen opaque to ultrasound and having a central aperture is placed in the region of convergence.
