Title: Information recording system from two sources - has each source moved past projection means onto common recording medium
IPC: G06F3/00
Filed: 1974-02-04
Abstract: The first source for recording, e.g. a photographic film (6) has a first information group, and a second information group characterising the latter, while the second recording source, e.g. a microfilm plate (20) carries information which is required to be combined with the first information group on the first recording source. The second recording source (20) information is displaced to bring a required area of the latter in front of the respective projection means (26), to allow the information from the two sources (6, 20) to be projected via a semi-reflective mirror (28) onto a common recording medium. A control unit (33) controls the displacement of the two sources (6, 20), search means (23, 24) for the second source, and the recording unit.

Title: Analysis of unsaturated organic cpds. - by ozone concn. change measurement, using UV detector and integrator
IPC: G01N21/33
Filed: 1974-04-09
Abstract: Double bonds in organic cpds. are determined by passing O3 through a reactor contg. the cpd. The ozone concn. of the exit gas is measured by subjecting to UV radiation and using a UV receiver which feeds an integration unit to measure the area circumscribed by the signal in time, which is proportional to the amt. of double bonds in the sample. The analyser combines high sensitivity with short measurement times and produces the result in the form of an electrical signal.

Title: Automatic waste disposal system - feed waste to storage point above shredder and separates too hard particles
IPC: B02C21/00
Filed: 1974-05-13
Abstract: The waste is transported to a storage point, where it is retained in bulk above low-speed shredders (5) until a predetermined volume is reached. It is then reduced into particles, eliminating what cannot be handled by the shredder since it is too hard and transferring it to a secondary storage point (9). Particles emerging from the shredder are transported by an air current flowing in a conduit (13) at a variable speed, and separated from the air above the final storage point (17) into which they fall. The air can flow in a closed circuit, and be heated. After a set number of operations, cleaning can be effected by a suspension of sawdust in the air current, after which a sterilising agent is injected.

Title: Alphanumeric character and language word recognition - uses object split by classic means, each element then being associated with binary variable
IPC: G06V30/194
Filed: 1975-03-11
Abstract: The alphanumeric and word recognition method has means of establishing equations relative to the different forms of objects of the group. The first member of each equation is made up of the sum of the binary variables by which the form of the object is defined. The second member of the equation is made up of an arbitrary number. The same equation is used for the different forms of an object. Different equations are used for different objects of the group. The method has means for resolving the equation, and for taking as unknowns the binary variables. The resolving means provide signals which are representative of new analogue values of the binary variables. Each variable binary is then replaced by its new analogue value in each equation. The equality of a signal which is representative of the sum of the new analogue values of the variables with predetermined amplitude signals is then measured. The amplitude signals being representative of numbers forming the second member of the equations.

Patent FR-2292764-A1 (FR)
IPC: C11D13/18
Filed: 1975-11-26
Abstract: In an extruder, the colourant is introduced through openings arranged in the extruder barrel into the conveyed composition, or differently coloured soap compositions are conveyed, at first separately, in different extruders and then merged in the vicinity of the extruder die with mixing. The extrudate consisting of the marble-coloured composition and possessing axially aligned veins is cut into shaped pieces which are subsequently subjected to an embossing process. In order that all the soap pieces have as far as possible an identical appearance, the soap extrudate (5), immediately after emerging from the extruder (1), is passed through two press elements (10, 11) arranged on opposite sides of the extrudate (5) and producing an undulating profile (12) of the marble fibres.

Title: Spring catch for door or window - has resilient catch and detent to operate from desired door position
IPC: E05C19/02
Filed: 1975-12-12
Abstract: Catches of previous designs ensure an effective operation when the door is used as swinging door, but offer unnecessary resistance when tilting operation is used. The design uses a housing (4) in which the latch (6) is resiliently seated, resting against the notch of element (11). The element is rigidly connected with a push rod (10) sliding in a slit of strip (9). When the door is used as a tilting door the push rod can be moved so that element (11) is out of contact with the resilient catch (6) and does not offer any resistance. In an alternative design the face of the housing is set back from the edge of the door leaf.

Title: Heated collar for fusion sealing thermoplastic bottle tops - for reliable closure without contaminating the contents
Inventor: BARLET ROBERT
IPC: B29C65/32
Filed: 1976-01-16
Abstract: Appts. for heat sealing the tops of thermoplastic bottles comprises a heated hollow metal cylinder with a bore having a convergent entry sized so that the mouth of the entry is larger than the outside dia. of the bottle neck, but the bore is smaller. The cylinder is located on the bottle neck, heated to melt the adjacent bottle mouth, and loaded with a weight to cause the cylinder to descend until stopped by a collar at the base of the neck. The bore is narrow enough to cause the bottle neck to converge and fuse solid. Pref. the cylinder is of metal which is a good conductor e.g. bronze, and heated by a coaxial induction coil. Used for sealing containers required to withstand rough storage and long shelf life, e.g. agricultural chemicals. One application is sealing of polyethylene bottles contg. potash. The seal is more secure than threaded or snap fit closures. There is no risk of melt droplets being dislodged into the bottle contents, unlike use of hot probes to fuse the inner wall of the bottle neck to receive a welded plug.
