Title: Ceiling mounted fluorescent lamp fitting - has one-piece tubular housing with demovable side faces with sliding insert for electric accessories
IPC: F21V17/10
Filed: 1975-05-06
Abstract: The light fitting for fluorescent lamps is held on the ceiling by leaf springs (14), with curled ends. The housing (3), is a tubular body of trapezoidal shape with side covers screwed on. The electric fitments, e.g. switches, starter, terminals, etc. are mounted on an insert (8) with dove-tail fitting in a guide (9), where it can slide. The housing is held at one end (15), curling more than 90 deg. round the leaf spring end, and the other end (15a) less than 90 deg. round the leaf spring, just clipping in. For access to fitments, one side cover can be dismounted, the side (15a) unhinged and insert pulled out of the dovetail guide as far as required. The complete light fitting is properly sealed and easily accessible for any maintenance without damaging the fluorescent tube (s).

The solvent is pref. 15-30% wt. on pigment, and ratio medium: pigment is >=300 (pref. 350-600) : 100. Process avoids the use of large amts. of conc. H2SO4 or org. solvents.
Patent CH-611097-A5 (CH)
Title: Window with printed heating grid
Inventor: ROSELLI SERGIO
IPC: B60S1/58
Filed: 1976-06-01
Abstract: The window includes a humidity detector comprising at least one sensor situated entirely, its supply terminals included, inside the minimum expanse of effectiveness (B, B') left free by the heating grid. The heating grid is controlled automatically by the sensor. This arrangement avoids the risk of heating remaining switched on in certain extreme circumstances when a sensor of high impedance is employed. It therefore enables the stability and reliability of operation to be improved. It applies mainly to vehicle windows such as automobile heated rear windows. <IMAGE>

Patent CH-639268-A5 (CH)
Title: Body massaging device
Inventor: MICHEL PETER
IPC: A61H23/02
Filed: 1979-08-31
Abstract: On a hard, shock-absorbing support (1) whose shape is adapted to the shape of the head of a driver, at least one electric motor (2) having an eccentric (3) connected to its shaft is fastened. The rotary movement of the electric motor (2) with the eccentric (3) which form a vibration mechanism located on the headrest of a vehicle seat results in the generation of vibrations which are transmitted to the support (1). Massaging of the back parts of the head and neck of the driver leads to improved blood flow in these parts and in disappearance of fatigue or pain which occur, in particular, when driving for several hours. <IMAGE>

Title: Food container covers - made of partially slit plastic film stretched laterally to open the cuts
IPC: B65D30/06
Filed: 1970-06-11
Granted: 1972-01-28
Abstract: Covers for open sided packages or baskets used for perishable foodstuffs etc are made from a homogeneous (plastic) film cut in patterns, to provide slotted zones to form windows or tear-open zones between zones of unbroken material when stretched laterally. The slits may be created in staggered or parallel rows using multi-knife rollers to cut tubular film or by use of suitable reciprocating die face cutters during extrusion of film. Unitary construction is simpler and stronger than composites made of alternate panels of netting and film or paper. The size of the openings in one pattern of slit film can be adapted for holding articles of various sizes.

Title: Plastic egg package - of semirigid transparent material
IPC: B65D85/32
Filed: 1970-11-09
Granted: 1972-06-23
Abstract: Two identical parts of a package joined by a hinge, consist of cavities in the shape of half an egg which mate together, the ends of the cavities being offset from the ends of the eggs so that the latter do not come directly into contact with the part of the cavity most exposed to shocks. The design minimises direct contact between the eggs and the cavities to eliminate shocks. The end protection of the cavities may be a cylinder projecting from the end. The two ends may differ so that the receptacles and the covers may be distinguished. Additionally the lateral walls of the cavities may be fluted. Holes in the structure provide ventilation. The package may be thermoformed from transparent semi-rigid plastics.
