Title: Triple casement bolt for door - has ramp faced tongues spring loaded outwards and bolts coupled to central mechanism
IPC: E05B15/04
Filed: 1976-04-01
Abstract: The triple casement bolt is particularly for mounting in a door leaf, having central, top and bottom bolts coupled to a common central locking mechanism. It is of the passive type, each bolt being formed by a ramp faces tongue which is spring-loaded outwards. The springs are independent of the common locking mechanism and the interconnecting linkage, which is only used to withdraw the tongues. The central lock may have a tongue coupled to an actuating mechanism acting simultaneously on the other two, which are thinner and situated near the leading edge of the door leaf.

Title: Titanium mfr. by electrolytic redn. of titanium tri:halide - gives high purity titanium with low iron content
Inventor: LORTHIOIR GERARD
IPC: C25C3/28
Filed: 1976-07-23
Abstract: Ti is mfd. by electrolytic redn. of a trihalide of Ti, esp. TiCl3, in a molten salt bath. The trihalide may be preelectrolysed in the presence of H2 to give a dihalide. Preelectrolysis is carried out in a cell in which the cathode is at a potential of -0.8 to -1.0 V w.r.t. a reference electrode based on the redox equilibrium Ag++e Into/out of Ag degree. The dihalide is reduced to Ti in the presence of H2 by applying a potential of -1.0 to -1.25 V to the cathode on which the Ti will be deposited. The current density is 10-30 A/dn2. Ti of high purity (99.994%) and low O2 and N2 content is obtd. which can be rolled without intermediate annealing to sheets 5/10 mm in thickness. Because of the low Fe content (is not >0.3 ppm) the Ti has electronic applications. The process may be continuous. The trihalide feeding the electro cell is produced in the same production unit used for mfg. Ti.
Patent FR-2321739-A1 (FR)
IPC: G10L15/08
Filed: 1976-08-16
Abstract: Sounds or speech signals are converted into an electrical sound and broken down into separate spectral components in a filter bank. These components are integrated over a short period of time and produce a short-time spectrum of the signal. The spectal components are applied, via a corresponding number of parallel leads, to a number of pattern detectors which supply an output signal only if the short-time spectrum corresponds to the pattern adjusted in the relevant pattern detector. To this end, each pattern detector includes two threshold value (window) detectors which supply a signal if the applied input signal lies between two adjustable thresholds. Each threshold value detector is connected to a different output of the filter bank for another spectral range and is generally adjusted to different threshold values. The outputs of the threshold value detectors are combined via an AND-element, so that a signal is produced only if all threshold value detectors of the pattern detector are activated. For each sound or for each phoneme in the case of speech, a pattern detector is provided. When series of sounds or signals are recognized, the series of addresses of the pattern detectors which have successively generated an output signal are stored and subsequently applied to the computer for comparison.

Title: Packing machine synchronising system with conveyor - varies machine speed dependent on intervals detected between incoming items (NL150377)
IPC: C13B45/02
Filed: 1976-09-10
Abstract: System synchronises the working speeds of a conveyor belt running at nearly constant speed, partic. for drying sugar lumps, and a packing machine with arms slewing across the belt, a reciprocating thruster acting in the lengthwise direction of the latter, and a suction unit. The latter receives and removes lumps assembled into a group by the arms and thruster. Detectors on opposite sides of the belt (1) and arranged at intervals along it determine the intervals between the lumps, and supply a circuit regulating the packing machine operating speed. The latter is increased, when the first detector passed by the lumps indicates that there is no interval between the lumps, above a predetermined speed. When the second detector indicates that the interval is greater than nil, packing machine speed is reduced below the predetermined value.

Title: Biological organic fertiliser prepd. from refuse - by three-stage fermentation process
IPC: C05F11/02
Filed: 1977-04-13
Abstract: Prepn. of fertilisers from solid town refuse and organic waste of any origin, size and compsn. comprises biological transformation at pH 4-8.5, a moisture content of 45-60% and a C/N ratio 25-35:1, in a plant which permits turning of the mass and its natural aeration which is controlled to give a temp. of 65-68 degrees C, and contg. the treatment until the pH stabilises at about 7 and until, in the 24 hr. after the maximal temp. has been reached, the temp. does not rise >=10 degrees C above that in the same part of the previous cycle. The partially fermented mass produced is then fermented anaerobically, but sheltered from the weather, in the form of bales which are turned and replaced each time a fall in temp. follows an initial rise, fermentation being complete when the rise in temp. after turning the bale is lower by 5-10 degrees C than the temp. in the preceding cycle. The obtd. mass is fermented after addn. of a microbial culture, isolated from the mass itself, which is a thermophilic organism with high degrading activity on the main organic substances such as cellulose, starch, protein, pectin, etc., fermentation continuing until the C/N ratio is stable.

Title: Mounting of maritime platform on hollow base with legs - includes submerging base using winches for elevating once platform is floated over
IPC: E02B17/02
Filed: 1977-08-08
Abstract: The installation process applies to maritime platforms e.g. for oil fields and entails the mounting of a platform on a submerged gravity type substructure whilst at sea. The substructure has columsn projecting from a hollow base block and is floated together with the platform to the permanent site. The connection is then made by submerging the substructure and floating the platform into the correctly aligned position overhead. The substructure is partially submerged by filling the base with sea water, and complete submersion effected by winches with cables to a sea-bed anchorate. Once the platform is located above, the substructure is allowed to rise, and the connection is made by platform winches with cables to the substructure. The assembled rig is now floated onto a prepared foundation at a nominally higher bed level.

Title: Detoxicating water from surface treatment bath - esp. for metal or plastic, using resistivity measurement as control means
IPC: G05D21/02
Filed: 1977-11-09
Abstract: The process comprises continuous measurement of the resistivity of the ringing bath for each type of toxic product to eliminate or for the whole bath by means of a probe immersed in the treatment bath(s). A resistivity level is fixed above which an electro-valve, commanded by the resistivity meter, opens to admit clean water, to reduce the resistivity to a fixed level. The polluted water withdrawn is passed to a purifcn. vessel where the exact quantity of detoxicant is introduced controlled by the resistivity meter. The process is carried out in an installation comprising (a) a rinsing bath linked to (b) a purificn, vessel; a source of fresh water for (a) and of detoxicant for (b); an electro valve on the water feed and a pump for the detoxicant controlled via a resistivity meter linked to a probe in (a). The process is used for the treatment of metal and plastics surfaces. It enables a reduction in the amt. of water and detoxicant used and is cheaper and easier than present methods.
