Title: Demountable convertible partition wall - has frame edge battens engaging grooves on panels locked by sideways movement
IPC: E04B2/74
Filed: 1975-10-02
Abstract: The demountable partition wall is designed so that it can be erected or dismantled, or converted, on site, with an min. of skille labour. A frame (1-3) attached to the ceiling, floor and vertical elements at the sides, has an edge batten (9) or more than one, parallel to the partition wall plane, engaged by a groove (5), also peripherally parallel to this plane, in the wall panels (7). Lateral connection between the panels themselves is effected by sideways displacement relative to the frame, so as to bring them into engagement with each other. There may be two parallel edge battens on the frame bearing two groups of panels which form the two sides of the partition wall. The groove on the underside of the panels may be fitted with rollers, enabling the panels to run on the edge batten of the lower part of the frame.

Title: Maximum security control system - for industrial installation uses printed circuit card system with faults in system actuating sound alarm
IPC: G08B25/14
Filed: 1975-11-12
Abstract: The control system uses several rows of printed circuit cards for signalling faults in the installation. Each row of cards is terminated by an "Alarm" card which controls an alarm relay and a winking light console. The system also has sequences of interdependent cards each actuating at the end of a sequence, under a given conditional state, a control relay of the interdependent function. A signalling card, corresponding to a determined fault, controls one or several interlocked cards. The printed circuits of all the cards being arranged so that the appearance of a fault in any control element of the installation actuates a round alarm and illuminates a lamp. The round signal is interrupted after a time and the lamp starts winking. The lamp is extinguished when the fault disappears.

Title: Road surfacing plant controls - are attached to special purpose vehicles enabling exact position to be determined distance recorded and sprays activated
IPC: E01C19/17
Filed: 1975-12-23
Abstract: The control equipment is attached to a specially-constructed vehicle. It has a gauge which is placed in front of the vehicle in such a position that the driver is able to determine the exact position of the strip of road which is to be covered. A mechanism records the distance covered by the vehicle and controls operate the valves on the sprays attached to the surfacing ramp. Readings from both the gauge and the distance mechanism enable the material to be placed in the correct position. The distance measuring mechanism functions by recording the number of times the vehicle wheels turn round and it can activate a light or sound alarm in the cab. It is also linked to the valve controls. The gauge, which is mounted in front of the vehicle, pivots on a support so that it follows any change in direction of the front wheels.

Patent FR-2341816-A1 (FR)
IPC: F21V7/00
Filed: 1977-01-27
Abstract: The indicator luminaire, in particular for rail-borne vehicles, comprises a baseplate (10) as the carrier of mounts with inserted incandescent lamps (25, 26), and a transparent hood covering these lamps. Two oppositely directed reflectors (18, 19) arranged offset relative to one another are mounted on the baseplate (10), each being assigned to an incandescent lamp (25, 26). It is possible by suitably arranging and constructing the reflectors inside the indicator luminaire to permit the light emitted from the incandescent lamps to be collected and projected with an intense luminosity into the region, e.g. of a platform, often frequented by train staff. Thus, the invention provides a substantial improvement in the lighting and signalling effect of the indicator luminaires simply by improving the optical system.

Title: Yarn guide device for textile winding machines - provides well-defined change from reserve tail wind to undulating spiral of main winding sequence
Inventor: POULIN BERNARD
IPC: B65H54/28
Filed: 1977-02-15
Abstract: Yarn guide device for winding yarn on to a rotating bobbin comprises a known vibration generator yarn guide (FR 2,199,743) driven by a compressed air source, and having a yarn-guiding groove of narrow width to form an undulating spiral yarn pattern, where the layers of yarn are offset from each other. The vibration generator yarn guide has an eccentric cam with a spiral ramp on its lateral periphery. The ramp is joined to the undulating yarn guiding groove on its circumference. Improvement comprises using the ramp as a transfer means from winding a stready undistributed yarn reserve tail, to moving directly into the undulating spiral of the main winding sequence. The change from steady wind to undulating spiral winding is well-defined, so the last wound part of the reserve does not become prematurely vibrated or undulated. The last part of the reserve is normally the most useful with regard to effecting the yarn joining between the bobbins. The vibrator guide is of simple construction and air driven, providing a stable speed and easy control.
