Title: Blade fuse socket with protective caps - uses caps with bevelled edges orthogonal to blade plane and with ventilating slots on fuse side and at lateral regions
Inventor: SCHULZ RICHARD ING GRAD
IPC: H01H85/00
Filed: 1977-09-14
Abstract: The socket is intended for low voltage, high power fuses, whose blades are to be retained in the socket clamps. The latter are protected against dangerous touch by caps (4). The latter are bevelled in relation to the ideal base plane of the socket (1). The bevel edge (6) extends at right angles to a plane containing the blade contact (3). The protective caps (4) have ventilation slots on the side facing the fuse cartridge and on both adjacent side. Preferably the caps have latches engaging beyond the springs of retaining contact (2), the latter being fitted with guide ribs. The ventilation slots may be formed laterally to an aperture for the contact blades.
Patent DE-2742229-A1 (DE)
Inventor: SIEWERT WOLFGANG DIPL ING DR
IPC: B01F7/00
Filed: 1977-09-20
Abstract: Such properties include, e.g., stiffness, thickness, flexibility, elasticity etc. The measuring appliance (1) contains a rotor (3) and a stator (2) having parallel surfaces, between which there is a gap (S) having a width of less than 1 mm. A measurement signal is formed from the friction torque between rotor (3) and stator (2), the rotational speed of the rotor (3) and the width (S) of the gap, which signal can be used to control an industrial refiner or a mixing appliance for pulps of different quality. The method and the associated measuring appliance (1) permit a novel measurement of the properties of pulp fibres based on their apparent viscosity, from which inferences can be drawn regarding the fibre properties mentioned, even during production. <IMAGE>
Patent DE-2750335-A1 (DE)
IPC: B60R21/01
Filed: 1977-11-10
Abstract: In order to release a connection between two parts, in particular a safety belt or a tether for an animal, the invention provides sensors (22) which respond to effects of fire, gas, water or mechanical influences and, under hazardous conditions, act on a lock (1, 2), via a control circuit (20), in order to release the connection (3; 6, 7). It is thus achieved that the connection is released under all envisaged hazardous conditions. <IMAGE>

Title: Communications system with several substations - initiating changeover of active state from one main station to second listening main station
Inventor: KIENZLE WERNER ING GRAD
IPC: G08C25/00
Filed: 1978-03-02
Abstract: The communications system has numerous substations and two or more main stations of which only one is active: the other listens in. The active function can be switched from one station to the other. One substation contains a device to receive and retransmit the signal sent from the active main station in order to transfer the active function to the other main station. The switching device connects the output of the receiver to the input of the transmitter in that substation in order to transfer the active function. Before retransmission the signals are stored temporarily and checked.

Title: Sepg. dust with high electric resistance from hot waste gas - by adding catalyst to convert sulphur di:oxide into sulphur tri:oxide, then using electrostatic filters
Inventor: VOESTE THEODOR DIPL CHEM
IPC: B03C3/01
Filed: 1978-03-03
Abstract: The gas is between the m.pt. of its ash and ca. 400 degrees C, and contains SO2; and a finely divided, conventional catalyst is added in dosed amts. to the hot gas to convert part of the SO2 to SO3, thereby improving the efficiency of electrostatic filtration of the dust. The powdered catalyst is pref. metal oxides, and esp. one or more of the metals Mn, Fe, Cu, V or their oxides. Alternatively salts of Mn, Fe Cu and/or V may be added, which are converted by the heat in the gas to oxide catalysts. Another pref. Alternative is to add Mn, Fe, Cu and/or V, or their oxides to oil which is burnt in the stream of waste gas. Provides an inexpensive method of conditioning the gas so the electric resistance of the dust is decreased, thus facilitating its electrostatic removal.

Title: Extrusion press for clay etc. - has feed rolls and extruder rotor with surface pockets filled with clay to reduce abrasion
IPC: B29C48/03
Filed: 1978-03-23
Abstract: The extruder contians a conveyor drum, and a feeder using two conveyor rolls. The drum and the two conveyor rolls possess recesses on their peripheries to form pockets in which part of the clay remains and sets, thereby reducing frictional wear of the drum and rolls by the clay. The conveyor rotor drum is pref. fitted with a row of disks with a zig-zag section closed by an outer ring to form the pockets, whereas the two feeder rolls possess surface grids forming square recesses. The deposits of clay on the peripheries of the drum and rolls preclude direct abrasion of these extruder components by the clay. The working life of the extruder, and its output, are both increased.

Title: Circuit comparing or forming ratio of two inductances - employs voltage which is applied to inductances and with time intervals to measure voltages which are necessary to reach same current
Inventor: SCHELLING BERND DIPL ING
IPC: G01R27/26
Filed: 1978-07-28
Abstract: A first and a second switch applies a specified voltage to the first and the second inductance during certain time intervals. A resistor derives two test voltages from the currents through the two inductances. A store stores the first test voltage at the end of the first time interval, and applies it to a comparator (8), to which the second test voltage is also applied. The comparator responds when the two voltages are equal, so that the ratio of the time interval from the second inductance connection to the voltage and the comparator responds, to the first time interval is equal to the ratio.

Title: Radiator with vertical flow medium sections - uses medium carrying steel pipes in ribbed cast aluminium with specified surface ratio between air and medium sides
Inventor: PFEFFER THEOPHIL DIPL ING
IPC: F28F1/16
Filed: 1978-12-11
Abstract: The radiator has individual vertical sections, through which flows the heating medium, and a surface, which radiates heat forwards. The radiator front has passages for the room air to be heated, while rear, base and side are sealed against penetration of unwanted air. This forms an upwards lift channel (7). When steel pipes (3) with strongly ribbed cast aluminium coating are used for the heating medium, the surface ratio between the air and heating medium side is at least 15 and at most 30. The ribbing is preferably horizontal, or rises slightly in the direction of the air flow. The ribs (4, 5) may be larger in the lower part, while the lift channel top cross section may be greater.

Title: Motor vehicle engine speed limiter - suppresses ignition impulses at preset engine speed, but has effect which can be overridden in emergency
Inventor: FIALA ERNST PROF DR
IPC: F02D31/00
Filed: 1978-12-14
Abstract: The internal combustion engine speed limiting controller is applicable to vehicles with a manual gear change. Its purpose is to limit noise emission from the vehicle, partic. in built up areas. The speed limiting effect is achieved by suppressing individual ignition impulses when a preset engine speed has been reached thus preventing any further acceleration. In order that increased engine revolutions are available in an emergency a switch is provided in the control circuit to cut out the limiter action. A signal lamp on the exterior of the vehicle indicates that the vehicle is operating in the unlimited, emergency power, mode when the switch is closed. The detector and limiter are typically electronic circuits and may, for example be switched into service only in the lower gears.

Patent DE-2927729-A1 (DE)
Inventor: GUBSER HANS
IPC: E01B29/00
Filed: 1979-07-10
Abstract: The object of this device is the installation of a load-bearing chassis on the track, which installation can be controlled from the cabin of the machine, without requiring any human presence on the railway track. With this device, a load-bearing chassis (4) suspended from the chassis (7) of the machine is guided during its installation by a guiding ramp (12, 15, 150) which is itself articulated to the chassis of the machine, in order to steer its two rollers (5, 6) on the two stretches of rail. For this purpose, the guiding ramp comprises two retractable feeler stops (16, 160) actuated by a jack (22) and the load-bearing chassis (4) comprises two fingers (11 and 110). During the lowering of the load-bearing chassis (4), these two fingers touch and then slide on the edges (15, 150) of the guiding ramp. The latter is then displaced laterally under the action of the jack (22) until the two stretches of rail are met by the feeler stops (16, 160) which have the effect of centring the ramp/load-bearing chassis assembly on the track. <IMAGE>
