Title: Cigarette filter tip for purificn. of smoke - regeneration of flavour and re-oxidn. of fluids
IPC: A24D3/06
Filed: 1974-08-29
Abstract: Cigarette filter-tip, is intended for mounting at the time of mfr. of the cigarette or subsequently by sticking with adhesive at one end. It consists of a light paper, acting as a general envelope, an assembly of filtering matls. and a closing disc. The filtering matls. consist of a mixt. of fine purificn. granules of silica gel, chalk and wood charcoal; these are rolled and compacted in a sheath of natur-cotton which retains them in position. The granules are dipped in a liq. with a special flavour; they strip the hot combustion gases of most of the aggressive prodts. and of their acidity resulting from the burning of the tobacco and the paper; at the same time the liq. charges them with a flavour comparable with that of the tobacco consumed. The paper of the general envelope is provided with a number of minute holes by which the outside air is drawn into the filter matls., by the smoker, and serves to re-oxygenate the absorbed fluids. The filter is intended for the protection and the satisfaction of the smoker. Deep purificn. of the combustion prodts. constitutes an effective defence against their aggressive nature.

Title: Multidifferential with combined satellite carrier and planet wheels - guides workpieces by contact at points along straight line
Inventor: DUCOL JEAN-PAUL
IPC: D05B35/10
Filed: 1975-07-22
Abstract: A multidifferential assembly has a number of differentials, each of which comprises a satellite carrier with at least two satellites, and two planet wheels; the assumed axis of rotation of all satellite carriers and planet wheels being the same. Carriers and planet wheels are designed to rotate, and in the assembly, two sub assemblies are input elements and another is an output element. Two end elements are provided with a number of elements in between, and an input or output and element is designed as a planet wheel. The satellites of each second element among the satellite carriers are at the same radial level relatively to the assumed axis of rotation. A number of the satellite carriers have on each face an outer or an inner planet wheel path formed by teeth or a surface on which rolling friction is possible, and have an inner or an outer satellite. Each end element has the form of a planet wheel. The multidifferential assembly has at least two output elements and each of these may acts as an input or an output element. All elements are free to rotate but are axially immovable on a common shaft. Each intermediate element is designed both as satellite carrier and planet wheel and has a circumferential surface allowing it to drive or to be driven. The assembly provides a multidifferential arrangement with numerous output elements, the speeds of rotation of which are in a definite ratio to the speed of the input element and to the speed of elements adjacent to each output element.

Title: Breakdown of oil and water emulsions esp. before effluent disposal - using four chemicals to coagulate with oil
Inventor: GRUET W
IPC: C09K23/00
Filed: 1975-11-12
Abstract: An emulsion of oil and water is broken up by coagulation of the oil into flakes which can be sepd. from the water by decantation or any other means. The novelty is the successive or simultaneous use of (1) hydroxide of Ca, Mg, or Ba, (2) ferrous or ferric sulphate, aluminium sulphate or ferric chloride, (3) potassium permanganate or other permanganate and (4) an agent promoting flocculation or coagulation. Manganese dioxide may be added to the emulsion to reduce the amt. of KMnO4 required; KMnO4 is pref. also added to the oil residues obtd. to eliminate the nauseating odour arising from bacterial action. A typical use is the removal of soluble cutting oils from aq. emulsions before the disposal of the water via drains. In this way the oil is recovered and pollution avoided. The process is rapid, economic, and requires neither special plant nor heating.

Title: Metal profile bending machine - uses bending and drawing process to obtain non-circular curve with former jacked into end anchored profile
IPC: B21D7/06
Filed: 1975-11-24
Abstract: The machine for bending metal profiles uses a combined bending and drawing process. The ends (26, 27) of the straight profile (1) are gripped by jack-clamps (2, 3).

Title: Automatic system to hold boat course in channels - using two alternating phase shifted magnetic fields and detectors on board
IPC: G05D1/02
Filed: 1976-01-29
Abstract: The method is for automatically holding an object such as a boat in a shallow channel on course using two alternating out of phase magnetic fields and suitable onboard detection equipment, and is relatively insensitive to signal amplitude variations. Two long electromagnetic loops (16, 17) are laid along the required path or course of the boat (15), on the bed of channel, to produce overlapping magnetic fields, out of place by 90 degrees when driven with suitable power amplifiers and transformers (41, 42).

Inventor: CHUITON RENE
IPC: G06F19/00
Filed: 1976-06-15
Abstract: The preprogrammed digital computer uses a calculating module associated with a transfer matrix for digital data and operation orders. The matrix is formed from connection lines and columns connected to the module. To the squares of the matrix are assigned figures 0, 1, 2-----9 and also the elementary operations which can be carried out by the module. Introduction of several digit numerical data or an order operation is carried by short circuiting the line and column of the square assigned to the value of the digit or operation. The computer has in addition prewired circuits formed by a group of gates each connecting a line and a column of the matrix. Sequential control circuits open these gates to transfer into the calculating module the digital values and the orders necessary for the calculation.

Title: Appts. to indicate end of useful filter cycle - comprising a stepping switching arrangement, used for domestic suction hoods
IPC: B01D46/42
Filed: 1976-07-02
Abstract: Appts. to indicate the end of a cycle of use of filters, partic. filters in a domestic suction hood. The indicator is activated by a button switch. A movable disc is connected to the switch through a communicating gear, a movement in a given direction being imparted to the moving disc each time the switch is used to start the hood.
