Inventor: SCHMID GUENTER
IPC: E06B9/11
Filed: 1992-02-12
Abstract: A roller shutter for furniture, in particular office furniture, consists of plastic roller-shutter strips (3, 4). In this case, a number of strips (3, 4) are in each case assembled to form a roller-shutter part element (5) which is joined together in one piece and the strips (3, 4) of which are interconnected in an articulated manner via film hinges (6) formed-on in one piece and arranged on the rear side (8). The ends of the part element (5) can be connected to the respectively adjacent part element (5) via an insertion connection. The side surfaces (18, 19, 20, 21) of the strips (3, 4) have, seen in cross-section, an arched region of curvature (22, 23, 24, 25) which extends at least over the central side surface region, one side surface (19 or 18) of the mutually facing side surfaces (19, 20 or 18, 21) of adjacent strips having an inwardly curved region of curvature (23 or 22) and the other side surface (20 or 21) having an outwardly curved region of curvature (24 or 25), which regions of curvature are identically curved so that, when the roller shutter extends in a plane manner, they bear against one another with their surfaces. <IMAGE>

Title: Appts. for laminating plastics prods. e.g. PVC films esp. in PCB mfr. - has vacuum chamber comprising 2 opposing movable platens, each having pressure mat backed by heating mats for receiving prod connected by thin polyester band
Inventor: NOWAK ALFRED DIPL ING
IPC: H05K3/28
Filed: 1992-07-07
Abstract: In the laminating arrangement a vacuum chamber comprises two opposing platens (10,15) movable towards each other, with edge frames. Each platen contains a pressure mat backed by a heater mat. The packet to be laminated is conveyed into the open chamber without touching the heated platens on a thin band, pref. of 12-36 micrometres thick polyester film, which is sealed with soft rubber seals. USE/ADVANTAGE - Useful for laminating films onto printed circuit boards, and laminating PVC, PE and PC films and similar materials. Device permits complete degassing of laminate before heating whilst flexible pressure mats permit uniform pressure on laminate. Also cyclic operation can be performed without manual handling. Costly and complicated drive for lower platen, acting as conveyor is avoided and the low heat capacity of thin polyester film reduces heat losses outside vacuum chamber, energy consumption and cycle times and improves handleability

Patent DE-4226107-A1 (DE)
Inventor: BULCSU ISTVAN
IPC: F26B13/10
Filed: 1992-08-07
Abstract: In known drying plant for printed and/or coated paper webs, the waste gas of the dryer, after addition of air which is drawn in via a cooling tunnel, is introduced into a combustion chamber in order to make the volatile solvents carried along with it harmless. The whole of the hot clean gas emerging from the combustion chamber is cooled by heat exchange with the inflowing waste gas mixture and subsequently by heat exchange with fresh air and is then discharged into the atmosphere. The preheated fresh air is supplied to nozzle boxes which are arranged on both sides of the inlet and outlet slot. The heat exchangers necessary are very large and a considerable part of the heat generated during thermal combustion is lost. The new drying plant makes possible with smaller heat exchangers an improved heat recovery. The outlet of the combustion chamber (3) is connected to the dryer (4) so that a part of the hot clean gas is guided back directly into the dryer (4). The suction pipe (15) starting from the cooling tunnel (5) is guided to its own suction blower (16) which on the pressure side is connected to the secondary side of the second heat exchanger (2). In this manner, the mass flows in both heat exchangers (1, 2) are reduced. Only a part of the clean gas is discharged into the atmosphere, and in particular at a temperature which is lower than the temperature of the dryer atmosphere. <IMAGE>

Patent DE-4230873-A1 (DE)
Inventor: FELGENHAUER KLAUS
IPC: H02H7/085
Filed: 1992-09-16
Abstract: The proposal is for a process and a circuit arrangement for electronically monitoring overloads on electric motor drives in which speed monitoring is used as well as the prior art method of true output monitoring.

Title: Variable cam-operated valve gear for internal combustion engine - shortens admission time at low speeds by allowing relative rotation of cam on camshaft through axial movement of locking piston
Inventor: SCHWARZENTHAL DIETMAR
IPC: F01L13/00
Filed: 1992-09-19
Abstract: A cylindrical piston (17) slides between two ends (15, 16) of a stepped recess (9) in the camshaft (2), which incorporates an axial bore (1) connected to an oil pump (25) by a valve (24) under electronic control (27). At high rotational speeds oil is pumped through a radial bore (13) into a chamber (20), driving the piston against a spring (19) into one end position (16) where the cam (3) is locked to its shaft. At lower speeds the valve is closed and the piston reverts to its other end position (15), rolling down the step and rotating the cam for earlier closure of the inlet valve (4). ADVANTAGE - Movement of cam into position for rotation wrt camshaft is achieved reliably by simple structure.
Patent DE-4233382-A1 (DE)
Title: Rotationally rigid torque-transferring coupling - has adjuster screws to tension slide guides and slide faces of coupling halves and centre piece relative to each other.
Inventor: POHL ANDREAS ING GRAD
IPC: F16D3/16
Filed: 1992-10-05
Abstract: The slide elements (4,4') have parallel slide faces (5,5') and interact with slide guides (3,3') when the coupling is assembled. The slide guides and slide faces can be tensioned against each other by adjustment elements such as adjustor screws mounted on the coupling halves (1,1'). Counter screws can be used to allow the adjustment of the coupling independently of the inherent elasticity of the coupling halves. The adjustment and counter adjustment screws can be mounted in through holes in the slide elements for even surface pressure between slide faces and guide faces. The holes can be larger than the screws to allow all round mobility of the coupling. USE/ADVANTAGE - The torque-transferring coupling is rotationally rigid and works free of play in the rotary direction. It is useful for shafts with torque reversals at high speeds.

Inventor: GROSMANN HOLGER
IPC: B01F5/10
Filed: 1992-11-19
Abstract: The invention relates to a process for dissolving a quantity of gas in a flowing liquid quantity, especially for dissolving carbon dioxide in beer, in which streams of liquid and gas are brought together and the gas is dispersed in the liquid, mixed therewith and part of it is dissolved therein. The invention is intended to increase the actual quantity of gas soluble in a liquid in given conditions as against prior art processes. In addition, the device for implementing the process is to be of simple construction, cleanable in place (CIP) and its adaptation to certain practical requirements and its regulation is to be facilitated to the utmost. Technically this is achieved in that there is a separation into a bubble-free stream of liquid (L1<*>) and a gas/liquid stream (G<*>/L2) taking the form of a two-phase flow, the gas/liquid stream (G<*>/L2) is fed back and together with the supplied unaerated or aerated flow of liquid (L1 or L1/G) and the gas bubbles are redispersed therein. The device for implementing the process is characterised in that a return line (7) is connected to the head of the separator (6), the return line opens on the other side at a second introduction point (9) into a section (1a) of a pipe (1), there is a second conveying device (8) in the return line (7) and the introduction point (4) in the return line (7) is arranged behind the second conveying device (8) or in the pipe section (1a), i.e. in front of or behind or at the second introduction point (9).

Title: Contactless safety sensor with PTC switch - has conductive tracks within housing which if broken due to mechanical damage of housing cause fault function to be signalled
Inventor: HISS ECKART DR
IPC: H03K17/95
Filed: 1992-12-15
Abstract: The safety sensor includes a front end sensor arrangement in a sensor housing. The sensor arrangement is connected to an amplifier. The electrical state of the sensor arrangement for external proximity acts upon operating elements, and the current representing the operating state of the amplifier is output at electrical contacts. One or more conductive tracks run within the housing so that an interruption of a track due to mechanical damage of the housing causes a signal on one of the amplifier contacts, which signals a fault function of the sensor. ADVANTAGE - Outputs signal when mechanical damage occurs to sensor housing for deduction of sensor endangering function.
