Title: Subscriber interrogation and response cable TV system - has digital signal concentrator with data store to address subscriber group
Inventor: REMY MAURICE
IPC: H04N7/173
Filed: 1974-06-12
Abstract: A central station communicates to subscriber units multiplexed carrier frequencies modulated by programme and digital interrogation signals. Each subscriber unit (3) has at least one data detector to process digital response signals for the central station. During transmission of interrogation signals from the central unit, and transmission of response signal from the subscriber units, the detectors of a group of units connected to the same distribution cable address the data to a digital signal concentrator (4) itself connected to the cable. The interrogation signals are the addresses of the group of units, sequentially delivered by central unit. Each concentrator has a data store for the group of units which it serves, as well as address recognition and data delivery circuits.

Title: Transportable refuse compactor for public use - has screw actuated vertical ram and protection grille at inlet
IPC: B30B9/30
Filed: 1974-07-25
Abstract: The compactor reduces the volume of paper containers of milk, tins, bottles and food residues. The press has a screw spindle and side opening for entry of refuse and the vertical press frame has at its lower region an inlet opening. The vertical press ram (37) travels in a chamber and refuse is compacted in a container. A protection grille moves in a vertical direction in relation to the movements of the compacting ram in the region of the inlet openings. When the protection grille is not closed then the control system provided returns the compacting ram upwards. A protection arrangement is also provided which ensures that the ram cannot be actuated when the refuse container is not correctly placed into the machine.

Title: Shut-off or multi-way valve with fluoropolymer-clad seat - grooves in seating ring prevent heat expansion loosening cladding
IPC: F16K1/226
Filed: 1975-06-17
Abstract: A valve for shutting off or diverting the flow of aggressive chemicals at =300 degrees C. has a housing with a metal ring either fixed in it, or forming part of the housing itself, on which the valve seat is formed by a cladding of a fluorine containing polymer, esp. of polytetrafluoroethylene, fluoroethylene-propylene, or trifluoromonochloroethylene. The metal ring has grooves in which the polymer cladding is anchored, and the flanks of the grooves subtend an acute angle with the adjacent section of the ring surface. One groove of the metal ring has moreover a dovetail section, and there is further groove in which an elastic rubber ring projects beyond the metal surface and exerts pressure on the seat cladding covering it. Even at very high temperatures, the polymer covering cannot swell outwards and be damaged by the metal valve body. The dovetail groove prevents the cladding moving either way, whilst the second metal ring groove prevents any axial motion.
Patent FR-2315508-A1 (FR)
Title: Simultaneous extraction and hydrolysis of saponins - to form steroidal sapogenins, using sulphuric acid and a lower alkanol
Inventor: PARIS NICOLE
IPC: C07J71/00
Filed: 1975-06-27
Abstract: Steroid sapogenins and industrially useful by-products are recovered from vegetable material containing saponins by a simultaneous extraction and hydrolysis, using a mixture of H2SO4 and a lower alkanol. Vapour from the alcohol extracts the saponin and the extract is hydrolysed by the acid, the acid not being permitted to come into contact with the vegetable material. The spogenins are recovered from the extract together with an insoluble residue. Sapogenins are starting materials for steroids, e.g. cortisones, sex hormones and contraceptives. The by-products from this process are proteins, suitable for animal feeds, and unsaturated oils, suitable for the manufacture of soaps, perfumes, paints, varnishes and foodstuffs. Better recovery of sapogenins is obtd. with less formation of spirosta-3,5-dienes. The extraction is usually carried out in a Soxhlet extractor, using a mixture of 0.5-3.0 N. H2SO4 and 30-95% lower a alcohol. In an example seeds of Papilionaceae were crushed and extracted in a Soxhlet with 150 ml 1.4N H2SO4 in 95% ethanol. The recovery of sapogenins was 0.8% on weight of seed, compared to 0.4% for conventional extn.

Patent FR-2287605-A1 (FR)
IPC: F15B15/00
Filed: 1975-10-09
Abstract: 1502980 Hydro-pneumatic intensifiers REUTI ANSTALT 25 Sept 1975 [10 Oct 1974 4 Aug 1975] 39234/75 Heading F1D In the device shown in Figs. 1 and 2, when compressed air is admitted through a port 11, a piston 8 and rod 9 are moved to the right by the combined action of air acting directly on the piston and by hydraulic liquid acting on the lefthand end 19 of the piston-rod. A free piston 13 transfers the air-pressure to hydraulic liquid and this is forced through ducts 14 to act on the pistonrod 19. When the rod 9 has been moved the desired distance at a relatively high speed with a low-pressure, e.g. up to a workpiece, compressed air is admitted through a port 22. This moves a piston 20 with a rod 21 to the right. After a small displacement, the rod 21 closes ducts 14 and the piston 20 and rod 21 act as an intensifier and move the piston 8 and rod 9 to the right with greater force. Fig. 5, (not shown), illustrates the final position. Fig. 7 shows a simplified embodiment in which the piston 8 is omitted. Air-pressure applied to the port 11' acts on the piston 19 through a free piston 13' and hydraulic liquid which passes through ducts 14'. The intensifier section 20', 21', operates as previously described.

Title: Underground long distance heating pipe - has insulating and protective layers of bitumen, glass wool, metal and rolled crepe
Inventor: PFEIFER JOACHIM
IPC: F16L58/12
Filed: 1976-03-01
Abstract: The underground heating pipe consists of an inner steel conduit, coated with a thin layer of bitumen. This is overlaid with a thick insulating jacket of glass wool. A sheet metal tubular shell encloses the glass wool, and there is a film of bitumen around this, with an outer finishing covering of rolled crepe paper or jute. The uninsulated ends of the steel tube are covered with detachable synthetic resin caps. The finished pipe is embedded in sand during laying, and may be welded to the foundation. This is feasible due to the flexibility and light weight of the heating pipe, which enables the pipe to compensate for temperature fluctuations.

Title: Shelving frame of demountable tubular components - has two post horizontal ladder frame and vertical H-frame modules
IPC: A47B87/02
Filed: 1976-03-12
Abstract: The tubular demountable shelving frame-work is built up from combinations of three modular components. The ladder frame (1) is rectangular in plan with the rungs (4) parallel to the bar (3) of the 'H'. The terminal rung (6), may be of inverted rectangular channel section. The channel section houses the bar (13) of the socket type 'H' frame (11). A shelving system is thus erected by coupling a ladder frame (1) to a socket type 'H' frame (11). Spigot type 'H' frames (3) are then used to extend the posts vertically when a subsequent ladder frame (1) and socket type 'H' (11) are installed.

Title: Pistol for putting cursors on two kinds of spinning-frame ring - has modified two part moving blade
IPC: D01H17/02
Filed: 1976-04-09
Abstract: The action of the pistol consists in taking a cursor from the upright position in which the magazine delivers it, turning it over, and clipping it into position on the ring. This is done with a two-part moving blade whose upper half performs most of the action of turning the cursor, while the lower half is mainly engaged in steadying it. To adapt the tool to suit conical rings as well as cylindrical rings, the upper blade has been made longer and bent downwards at the front, and a profiled stop has been added to deflect this blade's final motion, also downwards.
