Patent DE-2849780-A1 (DE)
Title: Pipe section and coupling permitting jointing by hand - has spigot with seal compressed by screwing into socket
Inventor: SIMMONS BILLY PAT
IPC: F16L47/16
Filed: 1978-11-16
Abstract: A pipe section has elements at its ends for connecting a number of sections together to form a pipeline for the transportation of fluids, esp. oil. The section consists of a tube consisting of resin-bonded inert filaments, which has, close to its ends, male and female screw threads for joining the sections together, whilst close to one end there is a compressible seal. At the opposite end of the section to the compressible seal, the inner surface of the socket is dimensioned to make a joint with the compressible seal which is secured in such a way that an effectively tight joint is brought about by one full turn of the two sections joined together, and ther correspg. axial motion. The pitch of the male and female screw threads relatively to the top angle of the inner sealing surface of the socket, and the size of the permissible play in the diameters, is such that an effective seal is ensured in a zone in which the screw threads engage over >=360 degrees. Arrangement overcomes the difficulties of jointing lightweight pipe sections either by adhesives or by screw threads. No tools are required by the pipe fitter, and the male and female threads can be screwed together by hand. One full turn and the correspg. axial motion ensure an effective joint. Index marks on the outside of the pipe show the operator that the screw thread are fully engaged.

Patent DE-2854742-A1 (DE)
Title: Electrostatic dust filter - with ionisation stage preceding separation stage with activated carbon lining
Inventor: FISCHER WOLFGANG ING GRAD
IPC: B03C3/60
Filed: 1978-12-19
Abstract: An electrostatic filter separates contaminant particles from dust laden media by passing them between two parallel electrode separator plates. In a first (ionisation) stage, the particles are charged by ionisation opposite to the charge on the separator electrodes. In the second (separation) stage, the electrodes are lined with an activated carbon layer over an insulating film. This removes even odoriferous matter from the filtered gas stream and firmly retains all separated particles. It offers a negligibly small resistance to the gas flow. The modular design offers advantages in mfr., assembly and service.

Title: Interrupter for main battery lead in motor vehicle - operated by inertia element on sudden collision to prevent ignition of petrol
Inventor: DEGEN KURT KARL
IPC: B60K28/14
Filed: 1979-03-07
Abstract: The main positive lead (34) from the battery (14) is passed through an interruptor, e.g. a relay contact (33b). The interruptor is initiated by the movement of a mass (20) in response to a sudden change in velocity of the motor vehicle. The action of the mass is tuned such that sudden but safe changes are without effect. The mass (20), in the form of a pendulum, can be connected by a cardan coupling (22) to an electrical auxiliary contact (26, 28). Movement of the pendulum closes the contact to energise the coil (33a) of a relay (33) and open a contact (33b) in the main battery lead (34). Alternatively, the mass is made to open the main lead mechanically.

Title: Radial bearing test device - has load shaft imbalance uniformly loading four test bearings on common test shaft
Inventor: NIEDEN ACHIM ZUR DIPL ING
IPC: G01M13/04
Filed: 1979-07-18
Abstract: The radial bearing test device with a variable uniformly rotating imbalance mass has a straight test shaft (1) rotating synchronously with it in four identical test bearings (4) in a straight line. It enables the bearings to be loaded with a load not necessarily reaching a null during a rotation and maintaining an equal amplitude each time w.r.t. the individual bearings. The frictional moment on each individual bearing can thus be derived from the moment measured as acting on all the bearings. The loads in the main and perpendicular auxiliary directions are independently variable. This facilitates nulling of the auxiliary direction load. The loading unit (3) has a loading shaft (6) parallel to the test shaft (2) and carrying the imbalance mass (7) loading the bearings (4) uniformly by its centrifugal force.

Title: Energy consumption meter with reusable data cartridge - has ultraviolet eprom logic circuits for recording peak and total power and interval power usage
Inventor: KENNEDY STANLEY PAUL
IPC: G01R21/00
Filed: 1980-11-20
Abstract: The appts. contains circuitry which enables energy consumed at a given location to cause pulses to be generated as a function of the instant rate of energy use. The pulses are counted at succeeding discrete time intervals. The succeeding interval summation count values are recorded in digital form at respective discrete locations on an ultraviolet UV light-erasable PROM (EPROM) contained in a removable cartridge. The interval summation count values are summed to provide a grand total consumption figure which is fed into and stored at a discrete location in the EPROM memory at the end of the recording period. The succeeding interval counts are successively compared and the peak count value for that interval having the greatest energy usage within a particular total time period composed of a multiple of such succeeding discrete time intervals is recorded on the EPROM at the conclusion of the particular total time period and the cartridge is removed.

Filed: 1981-05-22
Abstract: The invention relates to a device for setting an optimum folding process with respect to folding quality and folding performance taking into account the paper-dependent and format-dependent parameters and other parameters influencing the folding quality on folding machines with intermittently operating folding knives. The aim of the invention is, in order to realise the technology with the most favourable folding performance, to eliminate subjective influences in the setting of the folding machine by the operator. This object is achieved according to the invention in that a device capable of varying the speed for varying the belt speed of the feed belt and a device which can vary the cycle rate of the folding machine, for setting the folding knife cycle rate, are provided and are coupled to one or more electronic computers. Values characterising the folding process, for example format length, format width, paper characteristics, are input, via suitable input technology, as starting values for the computation. The computational unit calculates, according to an optimisation algorithm, the output data, preferably belt speed and cycle rate, which are converted into analog control variables. <IMAGE>
