Title: Sauna cabin for domestic installation - has door and rectangular shell, each with top panel with cutout for neck
IPC: A61H35/00
Filed: 1975-03-19
Abstract: The sauna cabin small enough to be installed in a house, e.g. in a bathroom, consists of a main shell with a seat (35) and feet support (39) closed by a door (17) at the front. The main shell has a panel (9) across the top, and the door carries a similar panel (23) each with a curved cut-out (25) at their abutting edges, to fit round the neck of the user. When the door is shut, these meet to enclose the top. Each cut-out carries a padded edging to fit the neck. The sides (3) are trapezium shaped, with one sloping edge, and one edge (15) carries the door hinges, so that when the door is shut, it is at an angle, sloping backwards.

Patent BE-1006590-A5 (BE)
Title: Surveillance system for works of art on public display - includes low power generator applying signal such that capacitive coupling provided by person disrupts circuit balance to trigger alarm
IPC: G08B13/24
Filed: 1992-02-05
Granted: 1994-10-25
Abstract: The protective system for works of art includes a very low power generator (G) with an output (X) connected via the primaries of a transducer (T) to cables (A1, A2) which lead to the brackets (C1, C2) on which the works are supported. The brackets hold upright supports (S1, S2) with suitable suspension frames for the works (P1, P2). The second output (Y) of the generator is coupled to earth, such that the works form a capacitively coupled circuit which is influenced if a person approaches and touches one of the works. This disturbs the balance of the transducer (T), such that a detector (M) senses the variation.
Patent CH-631398-A5 (CH)
Title: Aircraft using hot air for lift
Inventor: VIREDAZ RENE
IPC: B64B1/00
Filed: 1978-11-22
Abstract: The aircraft includes solar collectors (12, 13, 14) converting ambient radiation into heat, and an envelope (10) containing a mass of air heated by the collectors. The cold air enters by the orifice (22) and is removed through the rear orifice (20) providing its propulsion. This aircraft could be a small-scale remotely-guided model, using solar radiation as energy, with or without additional energy, or could also be used for observation flights, photography flights etc., as well as for transport of people or of goods. <IMAGE>
Patent CH-619609-A5 (CH)
Title: Brewing device for a coffee-making machine
Inventor: MEYER MANFRED
IPC: A47J31/22
Filed: 1977-10-06
Abstract: In a coffee brewing device constructed as a centrifuge, the layer (10) of ground coffee settles owing to the centrifugal effect on the inside wall of the hollow body (2). A bar (11) which can be immersed in the ground coffee with the aid of a stepping motor (14) brings about an even layer thickness of the ground coffee. A deterioration of the quality of the coffee due to an unevenly structured layer of ground coffee is thus reliably avoided. Since the bar (11) can be pivoted back from an operating position (B) into a rest position (A), the remaining functions of the centrifuge, for example filling, cleaning, etc., are not impaired. <IMAGE>

Abstract: The cigarette comprises a twist of tobacco, a filter, a strip surrounding the filter and an envelope at least partly enclosing the strip, both the latter having uniform porosity. A part of strip or envelope has a covering inpermeable to air, apart from the covering gluing strip and envelope, running along a selected zone. This gives the filter an index of ventilation of between 0, 5 and 20 cm per second, typically between 2 and 6cm per second. The total surface area of the remainder can be between 0.5 and 5 sq. cm, and it can be in the form of a strip placed round the filter in the peripheral direction.

Title: Measuring volume of radioactive sample
IPC: G01F17/00
Filed: 1969-02-26
Granted: 1970-12-04
Abstract: Two transparent precision-calibrated capillary tubes communicate at their ends with two reservoirs, common to both tubes. The first reservoir connects via a sealed tap to a filling funnel for measuring liquid and an orifice connected to a vacuum pump; the second has an open part, which can cooperate with a sample-carrier resting against it. A vertical frame supports the capillaries and reservoirs, and can pivot to tilt the tubes 180 degrees. The liquid level in the tubes can be read on a scale.

Title: Semi-automatic cutting or welding of synth- - etic fabrics for bags
IPC: B31B47/02
Filed: 1970-06-12
Granted: 1971-04-02
Abstract: A framework with a vertically reciprocating beam carrying a spring-tensioned hot wire for cutting or welding across layers of thermoplastic fabric which may be fed or pulled through the frame. The hot wire beam descends in response to an operator signal (e.g. foots witch controlling a motor and lever mechanism). The cut-off table span is adjustable to suit various lengths of bag. The hot wire is guarded, and the rise of the beam is automatically halted by a contact switch. Simple construction provides semi-automatic operation for sheet cutting, heat sealing or hot adhesive bonding operations, esp. for making plastics bags or sacks.

Title: Pneumatically operated volumetric membrane pump - peripheral fixings allow lower shell to be interchanged
IPC: F04B43/06
Filed: 1973-06-22
Granted: 1975-01-17
Abstract: A volumetric membrane pump which is pneumatically actuated, has two funnel shaped shells (1, 2) between which the membrane (3) is clamped, the upper shell (1) having an entry at the top (6) for the medium to be pumped, the lower shell (2) having an entry (7) for pressure air entry and extraction, which can be regulated by an eccentric valve member (20) to control the discharge of the medium. The periphery of the membrane is clamped between the peripheries of the shells by knurled nuts (15, 15a) on shouldered studs (9) which also located an intermediate clamping ring (11) with an annular groove (13) to fit over a rib (14) around the membrane to give a good seal. This design enables the lower shell to be replaced by another shell with a convex face, i.e. it bulges inwards and supports the diaphragm, stretching it inwards. This alternative shell has radial and circular ribs ensuring that the diaphragm does not stick to it when air is admitted under pressure, and the valve face, which touches the underside of the diaphragm, is curved for the same reason. This design is suitable for dispensing small quantities.

Abstract: The engine housing (31) is of square cross section with rounded corners. The outer surface is semi-circular in longitudinal section. The pistons (10) are semi-circular section in the longitudinal direction and curved in the plane of rotation. Each piston has a lug (15) attached by a pivot (13) to the rotor (9) on the shaft (7). As each piston passes the inlet (1) it draws in fuel and air until it reaches position (B). From (B) to (C) the charge is compressed and then ignited by the sparking plug (2). Expansion occurs between (C) and (D) until the exhaust valve (3) is uncovered. The exhaust strike occurs between (D) and (E) and the cycle is repeated from (F) to (A).
