Title: Heat exchanger for hot air generation
Inventor: JENSEN MADS
IPC: F24H3/08
Filed: 1986-07-09
Abstract: In a heat exchanger for hot air generation with a housing (7) closed off by two end plates (3, 9) and forming a channel, which housing is penetrated by heat exchanger pipes (8) for the air to be heated to pass through, there are sheet metal deflectors (4, 5, 6) arranged in such a way that the heating gases are forced to sweep over the heat exchanger pipes (8) at least partially in the transverse direction. For this purpose the heat exchanger pipes (8) can pass through the sheet metal deflectors (4, 5, 6) with a small clearance. The heat exchanger involved can be a component of a heater installation, in which the heating gases originate from a combustion chamber (11), which is also able to heat the air to be heated directly. <IMAGE>

Patent DE-3641862-A1 (DE)
Inventor: HEGE GUENTER DIPL ING DR
IPC: G01M13/00
Filed: 1986-12-08
Abstract: The device is intended in particular for inspecting circular-cross-section sealing rings known as O-rings. Two radiation sources (10, 11) are provided emitting radiation (12, 15) of a given frequency. The common light beam (16) is directed on to the surface to be checked (29) of the O-ring (24) by means of a beam forming system (20) and a first rotary mirror (21) as well as by a concentrating lens (22). The radiation (30) reflected from the surface (29) arrives at an arrangement of sensors (33) after passing through another convex lens (31) and deflection by a second rotary mirror (32). The sensor arrangement (33) comprises a first radiation sensor (34) which sends to an evaluation unit (35) an output signal which depends on the point of impingement of the radiation on the active surface (36) of the first sensor (34). Two further radiation sensors (35, 44, 49) are provided which supply the evaluation unit (35) with an output signal that varies according to the radiation intensity of said sensors (44, 49). Upstream of the latter are arranged colour-permeable filters (42, 47), the pass-band of one filter (42) being modulated to the radiation frequency (15) of the first radiation source (10), and that of the other filter (47) being modulated to the other radiation frequency (12) of the second radiation source (11). The apparatus described automatically identifies faults characterized by different geometrical and colour markings on the O-ring surface (29).
Patent DE-3642624-A1 (DE)
Inventor: BRAHMS MARTIN DIPL-ING
IPC: H02H3/06
Filed: 1986-12-13
Abstract: A circuit for protecting electronic devices which are fed from a source of dc voltage and to which a subscriber's line (ASL) is connected. In order to limit the current in the event of an overload on the subscriber's line (ASL), a MOSFET (T1) is provided as current-limiting component. The MOSFET (T1) is disconnected and re-connected periodically by means of a relaxation generator (K) when the MOSFET is in its current-limiting condition. Upon the normal operation of the circuit, the relaxation generator (K) does not operate. By proper dimensioning thereof, the time for which the MOSFET (T1) is blocked can be roughly adjusted as compared with the time in which it acts as current limiter. In this way, too great a heating of the MOSFET (T1) is avoided.

Title: Method and apparatus for making a knot
Inventor: LESCH HANS
IPC: B65H69/04
Filed: 1987-12-05
Abstract: A method and an apparatus for making a knot comprise the formation of a double loop in the form of a figure eight by guiding the thread through between at least two thread-deflecting mandrels, whereupon these are rotated in the thread plane relative to one another through approximately 270@, the thread-deflecting mandrels are rotated through essentially a further 180@ without thread engagement, and one of the free ends is guided through the assigned loop. The apparatus comprises a thread holder, the thread-deflecting mandrels rotatable relative to one another in the thread plane and displaceable in the axial direction and a needle which carries a hook at the end and which can be guided in the axial direction between the ends of the deflecting mandrels. A brake block engagement around the needle serves for retaining the released thread end when the knot is being pulled tight. Both elastically stretchable and inelastic threads can be knotted together, in the latter case the pivoting mandrels preferably being guidable towards one another when the knot is being pulled tight.

Title: Axial-piston unit
Inventor: EICKMANN KARL
IPC: F04B1/24
Filed: 1988-11-11
Abstract: In an axial-piston unit having a cam body forced against the rotor under fluid pressure, an additional holding-down means is arranged to reduce the load on the cam bedding area between the rotor and the cam body. All the other forces exerted on the rotor are kept under control by the novel holding-down means, without affecting the cam bedding area, so that the rotor remains forced against the axial bearing under all operating conditions. A piston/piston shoe/link pin arrangement makes pressures of up to several thousands of bar possible. The unit can be provided with a simple cam body which is slightly mobile in its seat and which contains exclusively cylindrical faces in addition to its planar faces.

Title: Method for changing programme-flow times, especially in domestic washing machines
Inventor: HENNINGER ALFRED DIPL ING
IPC: D06F33/44
Filed: 1989-01-25
Abstract: The flow times of a programme-switching unit or their steps are to be influenced in a functionally dependent manner. In a known programme-control device, a programme step is interrupted as a result of a physical state and is worked through in the subsequent step. The method according to the invention influences the time flow in a function-dependent manner, that is to say depending on whether a preceding programme step has taken place at all or not. The overall programmes become shorter thereby. During the "boiling and coloured laundry" programme, when "prewash" is selected a short running time is worked through. When the "prewash" is overrun, the running time is extended and thereby allows a longer activation of the inflow solenoid valve, that is to say substantially more water reaches the dry laundry which is thereby moistened more quickly. The method can be employed in domestic washing machines. It can also be transferred accordingly to dishwashers and laundry driers.
