Title: Centrifugal pump with canned magnetic coupling drive
Inventor: KRAEMER HERMANN
IPC: F04D29/12
Filed: 1983-10-12
Abstract: A centrifugal pump (1) has a canned magnetic coupling drive (2) and at least its can (4) is of plastic. At the same time this is outwardly enclosed by a metal casing (14). In the case of the plastic can (4) a greater stability of form and position is thereby achieved so that undesirable deformations are avoided, particularly at somewhat higher temperatures at which a deformation of the plastic used for the can (4) might occur. In addition, in the case of the pump, an internally completely sealed inner chamber formed of plastic and in contact with the pumped medium is at the same time obtained and this is also completely encapsulated by metal parts so that even if the plastic is destroyed in the event of sea-damage, an immediate escape of pumped medium is prevented. <IMAGE>

Patent DE-3405646-A1 (DE)
Title: Electronically controlled ignition system
Inventor: MINNER WILLY
IPC: F02P9/00
Filed: 1984-02-17
Abstract: The invention relates to an electronically controlled ignition system with an inductive ignition pulse generator for producing a control signal. The invention consists here in the fact that switching means are provided by means of which the ignition is inhibited as soon as the control signal reaches an adjustable reference voltage. This is preferably achieved in that the speed of revolution-dependent control signal is compared in a comparator with an adjustable reference voltage in order to detect the predetermined switch-off speed of revolution. An electronic system connected downstream of the comparator prevents either charge current from being able to flow through the ignition coil on the primary side or the primary-side flow of current from being switched off at the ignition time, as a result of which ignition is inhibited in both cases.
Patent DE-3409561-A1 (DE)
Title: Hydrostatic travel drive
Inventor: BRUGGER KLAUS
IPC: F16H39/40
Filed: 1984-03-15
Abstract: The invention relates to a hydrostatic travel drive for an off-the-road vehicle, with at least two hydraulic motors for driving at least one axle or its wheels, with at least one pump acting on the hydraulic motors arranged in a main circuit, with a flow divider arranged between the hydraulic motors and the pumps for locking the differential in travel operation, and with an equaliser connection between the main circuit branches to the hydraulic motors. In known travel drives of this type, the flow divider must be switched off under certain conditions, since otherwise the efficiency of the drive would be impaired when cornering. Expensive safeguards are necessary in order to ensure the functional reliability of the drive. According to the invention, a functionally reliable hydrostatic travel drive, functioning efficiently even when cornering with the flow divider switched on, is created in that a control valve is arranged between the main circuit branches, by means of which the passage through an additional flow cross-connection between the main circuit branches can be automatically controlled as a function of differences between the pressure differentials existing in the two hydraulic motors. Despite the differential lock being deliberately selected, the control valve provides for a differential equalisation when cornering.
Patent DE-3410122-A1 (DE)
Title: Oxygen sensor
Inventor: BREGLER JUERGEN
IPC: G01N27/406
Filed: 1984-03-20
Abstract: An oxygen sensor is proposed which serves to determine the oxygen content in internal combustion engines and furnaces. The oxygen sensor has a chip-like sensor element support which is arranged in the longitudinal bore of a metal housing and preferably projects out on the measurement gas-side. At least one layer-form oxygen sensor element is applied to this sensor element support, which does not need any air reference; in addition, electrical heating elements, temperature sensors and the like can also be arranged on the sensor element support. The measurement gas-side and measurement gas-remote sections of the sensor element support are not separated from each other in a gas-tight manner - as conventional hitherto - but are connected to one another via a gap having a thickness of up to 0.6 mm, which enables a significant simplification of the oxygen sensor construction. In addition, descriptions are given of advantageous combinations resulting therefrom having protective apparatuses for the sensor element and also advantageous methods for fixing the sensor element support. <IMAGE>

Patent DE-3443485-A1 (DE)
Inventor: WEISS RUDOLF ING GRAD
IPC: F16D3/79
Filed: 1984-11-29
Abstract: A flexible all-steel shaft coupling has two coupling halves each comprising a connecting flange and which are axially and angularly movable but antitorsionally connected to each other through a yieldable stapled lamella crown connected to the connecting flanges. Each connection of the stapled lamella crown with one of flanges consists of a bolt on which rests, in clamped position between spacer rings, the stapled lamella crown on a spring collet provided with a conical press seat. Due to its conical support on the bolt, the conical spring collet is radially expanded and transmits radial pretension into bores of the stapled lamella crown. Due to the tolerance-free support of the stapled lamella crown on the bolt, and due to radial pretension in the bores of the stapled lamella crown, the shaft coupling may be easily mounted without precision machning and without tolerance on the support seats, while expansions and ovalizations of the bores, which lead to ruptures due to notch corrosion are prevented.

Title: Device for changing, in particular heavy, broaching tools on vertical broaching machines
Inventor: GRAVEMEIER LOTHAR
IPC: B23Q3/155
Filed: 1984-12-22
Abstract: A device is to be created for changing, in particular heavy, broaching tools (8, 9) on vertical broaching machines (1) which have at least one slide (3) which accommodates a broaching tool (8, 9) and is vertically movable above a work-holding fixture over at least the length of the broaching tool (8, 9). 
<??>In order to achieve a rapid tool change with negligible risk of accident and with simple means, a feed device, receiving at least the broaching tool (8, 9) in a roughly horizontal position and conveying it relative to the broaching machine (1), is provided for transporting the broaching tool (8, 9) to and from the broaching machine (1). Furthermore, the top area of the broaching tool (8, 9) in the vertical operating position can be pivotably connected to the slide (3). A possibility of movement which is present at the broaching machine anyway in connection with the actual broaching is utilised here in order to take the broaching tool from a horizontal transport position into its vertical working position at the broaching machine.

Patent DE-3509630-A1 (DE)
Title: Apparatus for transporting workpieces into and out of machine tools
Inventor: MIESKES DIETMAR
IPC: B65G47/91
Filed: 1985-03-16
Abstract: The invention is concerned with a transporting apparatus for transporting workpieces into and out of a machine tool, in particular a press. In order in this case to be able to convert the transporting apparatus quickly and simply to the sheets to be transported, a gripper frame which can be laid into two holders and at the front end of which the suction cups for receiving the sheets are arranged in a way known per se is proposed. At the same time as the pushing-in movement of the gripper frame into the holders, the electrical and pneumatic connection is established by plugs and sockets arranged at the rear end, in the pushing-in direction, of a holder and of the gripper frame. This dispenses with the separate provision of the pneumatic and electrical energy supply and the consequent special handling of the corresponding supply lines (Fig. 2). <IMAGE>
Patent DE-3512676-A1 (DE)
Title: Sealing of vanes for a vane air pump
Inventor: STREICHER MAX
IPC: F01C21/08
Filed: 1985-04-09
Abstract: To avoid losses in the case of a vane air pump, each of whose slots is aligned with an opposite slot, whose vanes have extensions or are linked to one another by linkages or the like, grooves are recessed into the oblique longitudinal slots and are provided with sealing bars, the preferably round sealing bars coming to bear as a result of centrifugal force and frictional movement and thus considerably improving the efficiency, and the sealing bars being disposed especially at the lowermost side of the longitudinal slots, so that the forces with which the vanes come to bear do not interfere functionally with the sealing bars. By virtue of the preferably triangular cross-section of the grooves, there results non-forced sealing, both when the vanes are being extended and when they are being retracted. The play between vane and slot in which the vane is sliding can thus be increased substantially without adversely affecting the output, and thus operational reliability can be increased.

Patent DE-3514034-A1 (DE)
Inventor: BAAS DIETER
IPC: G11B7/00
Filed: 1985-04-18
Abstract: An automatic correction system for the servo-circuit of a device with optical scanning of a rotating information support, with a known servo-circuit (3) which announces anomalies in the scanning system (1) to whose outputs is connected a gate circuit, providing as necessary a mute control signal (MUTE) at the decoder (2) connected to the scanning system and thus ensuring the mute control of its outputs. According to the invention, anomalies in scanning can largely be reduced in terms of the disturbance caused by this phenomenon, by the fact that servo-specific indicator signals serve as a triggering criterion in the event of anomalies. This is achieved by the fact that on the basis of the current address data a recognition signal is formed in the comparison and correction system (6) by data monitoring (4) and by continuous storage (7); in this way, after the signalling of the termination of an anomaly a comparison is made between the old and new sub-code in order to form therefrom the appropriate correction signal, which is fed to the servo system (3) and which the scanning system (1) returns to the original scanning point.

Title: Method and device for a relaxation and stretching hanging bed
Inventor: KITZBERGER JOSEF
IPC: A61H1/02
Filed: 1985-06-25
Abstract: The invention relates to a relaxation and stretching hanging bed for universal application in the fields of health and fitness. This is especially intended for the prevention of pain in the back, ligaments and joints. By being suspended by the feet - using commercially available special foot cuffs - the body is unburdened and blood flow is improved. According to the invention, it is provided that a ladder be designed such that a cushioned lying surface is located in the middle. On the corners of the ladder combined with the lying surface there are rollers which serve to facilitate movement of the element and as a spacer relative to the wall when the hanging bed is suspended. The relaxation and stretching hanging bed is suspended in a rail fixed to the wall by means of a mounting. The hanging bed can be used universally in that the individual using the device sits in front of the device on the lower cushioning element using the special foot cuffs. By stretching the legs upwards it is possible to hook on to a rung which is easy to reach by means of the hooks present on the foot cuffs, and to pull oneself up to the desired height in a simple manner by hooking each foot alternately into the next higher rung, until the body has reached an optimum relaxation and stretching hanging position. In the same way, it is also possible to descend by hooking in each foot alternately.
