Title: Meat slicer depositing mechanism - has sliding plate consisting of several extendable late elements and has supporting mounting for packing paper roll
Inventor: KUCHLER FRITZ DIPL KFM
IPC: B26D7/32
Filed: 1978-02-18
Abstract: The meat slicing machine is fitted with a depositing table with an area which can be extended. the slicing cutter (3) driven by a control assembly inside the housing (2) deposits the slices of meat in direction of an arrow (5) onto a plate (4). The plate (4) is travelling on rollers (14) between stop lugs (15) and (16). The distance between the two represents the width of the plate unit in travelling direction. The depositing point for each row of slices remains the same in relation to the slicer assembly while the plate (4) travels step-by-step away from the slicer to create tows of slices. When the plate (4) reaches the terminal position ie. when the roller (14) stops at the lug (16) a carrier mechanism causes the uppermost plate unit (6) to slide on top of the next unit (7) underneath thereby extending the depositing area for a further supply of slices.

IPC: B61G5/00
Filed: 1978-03-14
Abstract: The dual-system rail track for passenger and goods transport has a main line in the form of an elongated track, with a drive rail comprising a hollow profile. Internal rails support motor running-gear frames from which cars for passengers and alpha or goods are suspended. Some cars are self-propelled motor wagons (12, 17b) each coupled to a motor chassis so that it can be uncoupled at any desired height at a stopping place or junction. Release is effected direct to an operating platform at elevated track level, or to a local route for further local transport. This is carried out by means of a raising and lowering appliance (7) on the chassis or ground.

Title: Proximity switch with logic and RC circuit - suppressing interference caused by alternating electromagnetic fields by introducing delay
Inventor: KREILE WERNER
IPC: H03K17/95
Filed: 1978-04-12
Abstract: The proximity switch has an oscillator coupled at its output to a flip-flop or trigger that operates an electronic switch, e.g. a thyristor or triac. The oscillator's output, or the output of the trigger is connected to its output, is passed to a logic circuit whose own output is coupled back to a first input and to a second input via an RC timing circuit at the oscillator's or trigger's output. The delay introduced by the RC circuit is at least half the period of any interference field and thereby allows alternating electromagnetic interference to be suppressed.

Title: Electrophoresis system using glass cell - which is in contact with electrode vessels containing electrolyte and closed by diaphragms
Inventor: PIFFL ERNST
IPC: G01N27/447
Filed: 1978-04-19
Abstract: The system measures mobility of electric particles in an electric field. It consists of a transparent glass cell and a corresponding optical system by which the movement of the particles can be observed. Two electrodes supply the voltage. The cell has electrodes collecting a voltage proportional to the field-strength in the cell. They can be quickly exchanged owing to the closure of electrode vessels filled with an electrolyte by two diaphragms. The cell is at first closed at its open ends by a foil which is removed for measurement, so that it is in direct contact through the diaphragm with the solutions in the electrode vessels, and thus with the supply voltage.
Patent DE-2822379-A1 (DE)
Inventor: DIEDERICHS HERBERT ING GRAD
IPC: F16D69/04
Filed: 1978-05-23
Abstract: A disc for a disc brake has a support (15) to which friction rings (16 and 17) are fixed by means of rivets (18). The support (15) and the friction rings (16, 17) are made by precision stamping. Fixing pins (23, 24) which fit into fixing holes (32, 33) are provided for centering the rings (16, 17) on the support. The pins (23, 24) are formed from the material of the support (15) by stamping. It is possible to arrange fixing pins and holes on the support as well as on the friction discs. Upon the precision stamping of the support, aeration channels (19, 20) may be provided by deformation of the material. Owing to the precision stamping, the friction rings are centered in a sufficiently precise manner so that, after assembly, it is not necessary to recenter them.

A first threshold switch is between the power switch and the resistor and has a delay element. A second threshold switch is between the power switch and the loads, and outputs of both threshold switches are connected to the setting input of a flip-flop whose blocking output is connected to the blocking input of the signal controller. Its resetting input is connected through the main switch to a voltage source.

Title: Reference voltage setting circuit for excitation controller - has only solid state components and includes storage integrator, subtractor, changeover switch, up=down counter and D=A converter
Inventor: HRZA EMIL DIPL ING
IPC: G05B9/02
Filed: 1978-06-27
Abstract: The reference voltage setting circuit is for the automatic excitation control of large synchronous generators. A signal proportional to the change in reference output (0) is applied to one input (VI) of an integrating store (1). The output voltage (0) is compared with the output of a digital to analog converter (7) in a differential network (2), whose output is fed to a change over control (3). If this error is greater than the insensitivity of the change over controller then the change-over switch (4) routes the error signal to the input of a polarity detector (5). An up or down counter (6) controls the output of the digital to analog converter (7) until the error is again within limits when the switch (4) returns to its normal position (X). A similar process follows the application of a + 10 volt signal to the second input (VII).

Title: Tubular hot gas filter - made of porous ceramic tubes joined by sealed bushes
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D46/00
Filed: 1978-12-28
Abstract: A fireproof tubular filter for hot gases is made of a porous rigid ceramic material. To produce the required length, each short tube section is joined to the next by a bush which is packed with an elastic refractory cement. For a radially inward gas flow, the composite tube can rest in a sealed bush on the bottom of the dust laden gas inlet chamber and is secured in the partition to the clean gas chamber by another sealed bush. This overcomes the difficulty of mfg. porous ceramic tubes in greater lengths.
