Patent CH-657513-A5 (CH)
Inventor: LUESCHER PAUL
IPC: A47J39/02
Filed: 1982-07-21
Abstract: The present invention relates to an apparatus for heating stackable dishes. The apparatus includes a shaft-like heatable housing with an open top which can be closed off with a cover. A support for a stack of dishes is disposed within the interior of the housing. The support moves translationally in the vertical direction on guide rails and is linked to endless chains which are driven by an electric motor. By operating the electric motor, the support with the stack of dishes is moved to a vertical position which is convenient for removing or inserting dishes. This movement may be executed following an automatic opening of the cover. The operator does not need to bend over or to stretch to reach the dishes. An automatic control further serves to lower the stack of dishes into the housing and to close the cover after the passage of a predetermined time interval at the desired vertical position.
Patent CH-641244-A5 (CH)
Title: Exhaust and refill valve for internal combustion engines
Inventor: KOTZUR HUBERT
IPC: F01L3/20
Filed: 1978-05-10
Abstract: The exhaust and refill valve has a valve disc (5) which is connected by webs (11, 13) to the valve stem (7). These webs (11, 13) define a domed chamber (14), which is located between the valve stem (7) and the valve disc (5). A conical elevation (20), which is directed towards the valve stem (7) and projects into the domed chamber (14), is also formed on the valve disc (5). The exhaust and refill valve is characterised by a simple design construction and a flow-enhancing shape. The resulting low flow resistances make it possible to achieve a high volumetric efficiency of the working cylinder and good evacuation of the latter. Furthermore, due to the fact that the hot gases led to and from the working cylinder flow freely through the domed chamber (14), the surface areas of the exhaust and refill valve acted upon by these gases are kept small, thereby preventing thermal overloading of the valve. <IMAGE>

Patent CH-653872-A5 (CH)
Title: Sofa bed
Inventor: DEGEN HUGO
IPC: A47C17/86
Filed: 1981-11-24
Abstract: Two pairs of guiding pins (17, 18) are fastened to the longitudinal edges (9) of an insertion frame (2) and two connecting link supports (15) are fastened to the longitudinal edges (4) of a mount (1). The profile of the guiding surfaces of the connecting link support (15) matches the pairs of guiding pins (17, 18) in such a way that the insertion frame (2) is locked in a stable fashion in its two final positions (ankle-high support and upper end position to permit access to the linen box) and is correspondingly retarded during its upward movement. Advantages, apart from the avoidance of noise and the protection of bed linen, include a high degree of operating safety (prevention of accidents). The insertion frame (2) and the mount (1) can be delivered separately and can be assembled in situ simply by placing one on top of the other. <IMAGE>

Title: Incinerator for domestic refuse - with preheated secondary air provided under pressure
IPC: F23G5/14
Filed: 1973-06-01
Abstract: The incinerator includes a combustion chamber (1) under a dome (2), and is fitted with a loading door (4) which closes the loading hatchway (5). The burner (7) is supplied with primary combustion air by the blower (8) and ashes are allowed to fall into the ash can (10). Exhaust gases escape through the side grille (15) in the sidewall of the combustion chamber to the flue (17). The secondary air supply is fed under pressure to the combustion chamber through the feed holes (19). The secondary air is fed by a blower and the supply pipes cross the hot flue gas escape passage. As the secondary air flows against the flue gases any unburnt particles in suspension will be dispersed in the combustion chamber.

Title: Accelerator for sepg. particles by different weights from fluid
Inventor: JENSEN DONALD CAMERON
IPC: B01D45/16
Filed: 1974-12-24
Abstract: An accelerator for a fluid contg. particles of different weights which have to be sepd. from one another, comprises a helicoidal duct of progressively diminising dia.  The duct consists of adjacent coaxial rings with concave inner surfaces.  The distance of the surface from the axis diminishes in the direction of the periphery.The first ring has an inlet for a fluid under pressure. Each ring has an inner sloping surface part, in the zone where the inner surface is nearest the axis, so as to direct the fluid into the following ring.  The last ring opens into a cylindrical coaxial chamber of a larger dia., fitted with pipes for withdrawing particles entering the chamber.  The pipes can be moved along a longitudinal axis.The accelerator can be used for economically and rapidly separating particles from a fluid, and for efficient combustion of a fuel.  Applications include sepn. of fresh water from contaminated wateR, sepn. of petroleum components and treatment of waste gases. Problems of large size, complexity and high cost, associated with e.g. distillation and centrifugation, are avoided.

Patent FR-2076551-A5 (FR)
Title: Leather forming - eg for shoe uppers
IPC: C14B1/00
Filed: 1970-01-19
Granted: 1971-10-15
Abstract: Leather is formed by a process in which a sheet of leather or skin is applied over a punch by means of a deformable membrane, the faces of which are subjected to a differential pressure. As applied to the shaping of a shoe upper, the leather is held by adjustable grips in a fixed frame, this is placed over a punch, which has a profile corresponding to the shape it is intended to make, and is placed on a hollow platform mounted on the rod of a jack. The platform is raised so as to preform the leather and a deformable membrane is placed over the fixed frame and is secured to a movable frame. A vacuum is then applied to the platform and the atmospheric pressure presses the skin tightly against the punch via the deformable membrane. Heat is applied to release the stresses and the skin retains its new shape. The method avoids any risk of the leather sliding over the punch and prevents the formation of pleats which wound render the shapes useless.
