Title: Continuous mfr. of clothing of warp knitting machine - with simultaneous mfr. of belts, binding tapes etc.
IPC: D04B21/20
Filed: 1975-05-27
Abstract: Articles of clothing, e.g. underwear, nightdresses or boleros, are manufactured on a Jacquard double-rib loom by continuously knitting the article with any motifs in relief patterns or lace patterns. Fringes and threads running in the warp direction are worked into the article as dividing means, so that the finished articles and their accessories can be separated from each other by subsequently cutting through the fringes in a direction perpendicular to the warp direction and pulling out the longitudinally extending threads. Neck openings maybe incorporated in the fabric periodically at intervals determined by the Jacquard cards. In the longitudinally extending central portion of the fabric may be knitted belts which are connected to the main portions and fringes by the dividing threads.

Patent FR-2291299-A1 (FR)
Title: Controlling carding device using density sensor upstream of feed rolls - to vary feed or delivery roll speeds to ensure uniform density
IPC: D01G23/06
Filed: 1975-09-30
Abstract: The parent patent describes a carding device including a density sensor to measure the density of the fibre lap and continuously adjust the speed of the fibre feed or fibre delivery rolls to maintain the density of the lap constant. The sensor pref. comprises a radioactive source and a radioactive sensor which detects radioactivity passing through the lap in or adjacent to a zone in which the lap passes through a nip formed between a presser roller and a fixed table. In the improvement the density sensor is positioned immediately upstream of the feed rools through which the lap passes into the carding device. The tension on the lap between the fixed table and feed rolls simplifies control of the volume of matl. Since the density of the lap is measured as it passes into the carding device the delay in controlling the fibre feed or fibre delivery rolls doesn' have to be built into the control system.

Title: Air conditioning for underwater working areas - using sea water to cool separator and emulsify used air with purified air also used to cool separator
IPC: F25B9/00
Filed: 1976-03-05
Abstract: The unit conditions air in underwater working areas and uses an oil-free rotary compressor drawing in the used air. This is mixed with sea water from outside the chamber to form an emulsion. This passes into a centrifugal separator where the purified air is released upwards through a cooling coil. After reducing its pressure, this air passes through the same coil as a cooling fluid and is returned for use after preheating. The separated water is returned to the sea after passing over submerged coil. The heat from this separated water heats the sea water used to supply the compressor.

IPC: E04B1/04
Filed: 1976-07-16
Abstract: The welded site-connection is for use between precast concrete building components, joins steel fittings which are embedded in the conjunctive concrete components, and avoids the time lost in waiting for in situ mortar connections to mature. A hammer head projection (6) from the edges of the floor slab is formed by opposed identical groves (4, 5) in the invert (16) and soffit (23) faces of the floor slab, and fits in a reciprocal section channel (7) in the internal wall face. The channel (7) centres on the panel bed-joint (9) and comprises half-channels formed in the abutting internal corners of the wall panels (2,3). The steel connectors take the form of angle irons (10-18) set flush or slightly recessed in the wall panels (2,3) and plates set in the roots of the hammer head.

Title: Colour density measurement of chromatograms - using opto-electric conversion and line-by-line resolution of video signal (HU 28.12.76)
Inventor: KERENYI GYULA
IPC: G01N30/95
Filed: 1976-07-22
Abstract: The colour density of an image is measured by first converting the image into an electrical video signal. This is then resolved line-by-line; each line sampled and its signal level compared with standards. By digital conversion the signal level at each point (which is proportional to, the colour density) is counted up, displayed and printed. Used for the quantitative analysis of chromatograms, elphograms, autoradiogrames, photographic reproductions or copies. The analysis method is much more rapidly than the time-consuming use of densitometers.
