Filed: 1991-11-17
Abstract: This method can be used to produce dental prosthesis parts, such as inlays, onlays or crowns with high fitting accuracy and at low cost during only one visit of a patient to the dentist. For this purpose, a curable material is used for the preparation of the impression (proinlay) of the dental cavity. After curing, the material is removed. During a first processing stage, coarse scanning of the proinlay (4) by a first sensor (7a) and coarse processing of a substrate body (6) by means of a first processing tool (30a) are carried out. During a second processing stage, fine scanning and fine processing by means of a second sensor (7b) and a second processing tool (30b) are carried out. During this, the sensors (7a, 7b) and the processing tools (30a, 30b) are located on a common linear table (13). The proinlay (4) and the substrate body (6) are fixed to receiving parts (3, 5) of a rotation synchronisation device (10) arranged on a displacement device and a lifting device (11, 12). <IMAGE>

Patent CH-647067-A5 (CH)
Title: Heat exchange system
Inventor: WADKINSON GEORGE WILLIAM JUN
IPC: F28D7/10
Filed: 1980-07-04
Abstract: The heat exchange system has a heat exchanger with three tubes (20, 22, 24) placed one inside another and a distributor on each longitudinal end of the heat exchanger for the circulation of a fluid through the outer tube (20) in a counter current to the fluid which flows through the inner tube (24), with the result that heat exchange occurs between the two. In the tube (22) arranged between the outer and inner tubes, a fluid is present so that a leak in the outer or inner tube can be detected. Each tube has fins (100, 106, 112) directed radially inwards, the fins of the outer tube being in good thermal contact with the intermediate tube (22), the fins (106) of which are in good thermal contact with the inner tube, with the result that there is an effective heat flow path therebetween. Such systems can co-operate, for example, with solar collectors. <IMAGE>

IPC: D05B69/18
Filed: 1979-06-13
Abstract: A rocker (2) is supported, such that it can pivot, on a housing (1) by means of bearing pins (3). Arranged inside the housing (1), which consists of an insulating material, is a resistance winding which is tapped by a sprung contact lever (12), which is in driven connection with the rocker (2), by means of a contact element (11). Arranged in the region where the contact element (11) moves into the switched-off position is a guide surface (33) which projects from the resistance winding into the path of the contact lever (12). The guide surface (33), which consists of insulating material, is expediently arranged in the path of the contact element (11), which is constructed as a roller. Such an arrangement achieves sudden current disconnection in order to prevent damage to the resistance winding, by arc formation, without any additional switching elements. <IMAGE>

Title: Method for producing a cigarette filter unit and the cigarette filter unit produced according to the method
Inventor: BOEGLI SERGE
IPC: A24D3/02
Filed: 1976-11-26
Abstract: To permit production of a cigarette filter which is provided with a chamber containing a pourable filter material and permits a view into the said chamber, an enclosing strip is used which is made of a transparent material and the width of which amounts to at least 75 % but no more than 93 % of the circumference of the filter elements to be enclosed. The filter elements are fastened to this transparent enclosing strip so as to be evenly spaced and are enclosed by the said strip, with the formation of a suction slot which extends along the filter rod and is of constant width, and with the formation of filling apertures of constant width. Once the chambers have been filled with pourable filter material by means of a suction and filling part which lies on the top of the filter rod and on the edges of the enclosing strip in a sliding and sealing manner, the suction slot is sealed by means of a sealing strip, It is possible in this way to obtain chambers which are tightly filled with pourable filter material and absolutely clean outside surfaces of the filter element.

Title: Gate valve
Inventor: TROESCH PAUL
IPC: F16K3/28
Filed: 1977-12-16
Abstract: The gate valve is manufactured from plastic components and comprises a housing (1) with a two-part housing neck (2), a gate (6), a non-climbing actuating spindle (4), an adjusting nut (5) and at least one spring (24) arranged to act between the nut (5) and the gate (6).

Title: Fluid medium drive arrangement - has expandable cells carried on shaft eccentrically mounted within cylindrical housing
IPC: F01C9/00
Filed: 1973-12-11
Abstract: The drive is for producing a rotary motion by means of a fluid or gaseous pressure medium in which a working shaft and an eccentric part within a housing are acted upon by at least one freely deformable expansion cell mounted between the housing and the eccentric part, such that expansion of the collapsible cell exerts a rotational moment on the eccentric part, a force that is directed along the central axis and therefore along the working shaft. The expansion cells are connected with the working medium by suitable control means. The arrangement does not allow sudden peak stresses within the chambers.

Filed: 1970-11-13
Granted: 1971-09-03
Abstract: Water-extendible thermosetting polyester resins used for the production of lightweight casting or mouldings. The polyester is mixed with water, a catalyst system (suitably Co octoate, dimethylaniline and methylethyl ketone peroxide pref. about 2% catalyst referred to resin) and 3-7% of a surfactant with a hydrophilic/lipophilic equilibrium value of 1-9 (preferably a sorbitan fatty acid ester, especially sorbitansesquioleate) to form a water-in-oil emulsion, to which a mineral aggregate is added to aid the release of water after casting. The surfactant used is particularly able to allow the removal of water after activation, extending, emulsifying and curing of the resin. Up to 90% of the water can be removed from the cured casting. The finished article can be sanded, sawn, polished, worked or glued, mixed with fillers and used as a substitute for wood, gypsum, ceramics or other plastic. It can be painted.

Title: Finger roll coating line
IPC: A23G3/20
Filed: 1971-01-04
Granted: 1971-11-12
Abstract: All round coating by passing the fingers or rolls along two parallel level toothed rails, using a lifter bar between which also has teeth in phase with those on the rails. The lifter raises each finger clear of the rails, moves on and then lowers it onto the receiver ramp in the next tooth recess of the sawtooth pattern forming the rail serration. These ramps allow the finger to slide down and thus present the next sector of its surface for coating by one of several coating curtains provided along the process line. The Transporter or lifter bar is carried at two eccentric points to provide the lifting and transporting movements at various parts of its circular trajectory. Even coating, all round, without drips or foot formation, as well as gentle handling it obtained.
