Title: Compressed air brake system frost protection pump - has storage chambers for liq. frost preventative round and below stepped piston
Inventor: DEIKE KARL-HEINZ
IPC: B60T17/00
Filed: 1980-10-22
Abstract: The frost-protection pump housing (1) has inlet (13) and outlet (14) unions connected to the compressor and the system supplied, also a storage chamber (3,9) for the preventative liq. which is delivered by a stepped piston (2) actuated by compressed air. The piston actuates an inlet valve (16,17), through which the preventative is delivered into a chamber (15) in the housing through which the compressed air flows. The storage chamber comprises an annular section (3) round and a further one (9) below the smaller-diameter portion (2a) of this piston. A recess (7) in the periperhy of this portion accommodates a floating O-ring (8), bearing on the outside against the wall of the housing bore in which this portion works. In the rest position, the annular chamber section (3) is connected via a passage (11) between the smaller-diameter portion and the bore, past the O-ring and via ports (10) to the other chamber section. The O-ring acts as a non-return valve, shutting off this passage on piston movement.

Title: Device for preventing scalding
Inventor: KAPPE ANGELIKA
IPC: F16K17/38
Filed: 1981-03-06
Abstract: In the case of said device, the invention provides a member which reacts to the temperature of the medium flowing through the device and is designed such that, given a predetermined temperature, a closure member braced in the closing direction is disengaged from its catch and guided into the closing position. The closure member is configured as a slide which, in its closing position, permits the line which is located downstream to empty media which are too hot into a separate emptying channel (4) via emptying openings (27). Moreover, in the closing position, the medium which is too hot and is located upstream of the closure piece is fed to the emptying openings (27) through throttle openings (25), with the result that it is ensured that a medium having a temperature above the operating point cannot be unintentionally discharged at consumer points. <IMAGE>

Title: Circuit arrangement for clock conversion
Inventor: BOEDEKER FRIEDRICH ING GRAD
IPC: H03K5/00
Filed: 1981-04-07
Abstract: The invention relates to a circuit arrangement for converting a clock with the frequency f1 into a clock with the frequency <IMAGE> At clock frequencies in the MHz range, it is no longer possible to start from a master clock which is higher by a multiple than the required clock in the clock conversion. It is therefore proposed to divide the original clock with the frequency f1 by the factor m and logically to combine the resultant pulse sequence with the original pulse sequence. The required frequency f2 is then filtered out by means of a narrow-band filter from the frequency mixture of the logically combined pulse sequence. <IMAGE>

Title: Device for monitoring tears in binders or designation windings on twisted strands
Inventor: FROESCHER PETER ING GRAD
IPC: D07B7/08
Filed: 1981-09-16
Abstract: In the case of twisted strands (7) which have to be fixed or marked in the course of production by means of a binder (16), the complete failure of the fixing due to tears in the winding is largely avoided by applying two mutually offset windings (16, 17) to the strand (7). In the novel device for monitoring tears in the two windings, two electric signal transmitters (25a, 25b and 26a, 26b) are arranged in the flight circle of the windings (16, 17) and in the path of rotation of the spinner (11). The signals thus generated are fed to an evaluation circuit (30) which essentially consists of pulse counters (35, 36) and a comparator (37). The outputs (38, 39, 40) of the comparator permit signals for the possible states when one or both windings are torn or when both run undamaged. <IMAGE>

Title: Loading station for railway wagons
Inventor: STOG WILHELM DIPL ING
IPC: B65G67/22
Filed: 1982-05-18
Abstract: For loading railway wagons, in particular one-side self-discharging wagons, with coke at loading stations of coke-oven plants, continuous loading without breaks in between is achieved by a breeches chute, having two chutes extending at an angle with respect to each another, being assigned to the belt tripper, one chute being designed such that it extends approximately vertically and the other chute being designed such that it extends obliquely at an angle thereto. The approximately vertically extending chute comprises individual segments which can be pushed one into the other, with the result that said chute can be lowered, in the form of a trunk, onto the floor of the one-side self-discharging wagon. A continuous operation, which preserves the lump form of the materials handled, of such a loading station is thus ensured. <IMAGE>

Patent DE-3228387-A1 (DE)
Title: Method of screening halftone image motifs
Inventor: MUELLER HANS
IPC: H04N1/405
Filed: 1982-07-29
Abstract: A method of screening halftone image motifs, in which method the picture halftones of the halftone image motif are reproduced by changing the intensity of the structure of a basic screen structure of any form. The allocation of the picture halftone area of the halftone image motif to the intensity of the screen structure reflecting this picture halftone area can be specified in a targeted manner. In a phototechnical version of the inventive method (Figure 1), any desired basic screen structure (1) is made and expanded screen structures are made from it as negative films (9, 11). From the image motif (13) to be screened, the same number of tone value extracts (20, 22) is produced as negative films, each of which reproduces a particular picture halftone area of the halftone image motif which can be adjusted by the exposure time. The tone value extracts (22, 20) are exposed with the expanded screen structures (9, 11), assigned to them in each case, of the row onto a strip material (24) which then reproduces the screened image motif in such a way that the picture halftone proportions defined by the tone value extract are reproduced locally by the intensity of the screen structure assigned thereto. Of this method there are several phototechnical and EDP-scanner-laser variants which are suitable for screening halftone image motifs, for producing screened printing copies and for printing on recording media with image motifs screened in this manner. <IMAGE>

Title: Ignition device for internal combustion engines
Inventor: LATSCH REINHARD DIPL ING DR
IPC: F02B19/10
Filed: 1982-08-19
Abstract: The ignition chamber plug (2) has transfer ports (17) for connecting its ignition chambers (34, 35) to a main combustion chamber (13) of an internal combustion engine, two expansion pipes (10, 11) with free ends (19, 22) directed towards one another and an earth electrode (9) and an insulated electrode (8) inside the expansion pipe connecting to the transfer ports and a gas receiving space (25, 26, 27, 28) outside the expansion pipes. As long as the expansion pipes are essentially cold, a transfer cross-section (23) exists between them. This connects the ignition chambers (34, 35) to the space (25, 26, 27, 28). When the internal combustion engine is idling or at partial load this space receives used gas from a preceding combustion and fresh mixture, so that fuel-air mixture reliably passes between the electrodes on the compression stroke of the internal combustion engine. At higher loads of the internal combustion engine the expansion pipes heat up and close the transfer cross-section. As a result the effective chamber volume is reduced, which reduces the heat losses of the engine, that is the achievable power and the torque are increased. <IMAGE>

Title: Filter and demodulation circuit
Inventor: HANSEN JENS DIPL ING
IPC: H03D3/00
Filed: 1982-08-26
Abstract: A filter and demodulation circuit for the intermediate frequency of a frequency-modulated carrier is proposed which has a correctable filter, a demodulator following this filter and a network (18) connected between the demodulator output and the control input of the filter. The network forms from the output voltage of the demodulator (14) a correction voltage which takes into consideration the filter delay and which is added to the filter-correcting voltage. In detail, the output voltage (UA) is clocked and supplied via a storage capacitor (27) to a first input and also unchanged to a second input of a subtraction circuit (24) and the difference (UD) is supplied via an envelope curve detector (34) to one input (37) of an addition circuit (32), at the other input (31) of which the output voltage (UA) is present. The aggregate voltage at the output of the addition circuit is then a corrected filter-correcting voltage (Z). <IMAGE>

Title: Powered hand tool for percussive or rotary-percussive mode of operation
Inventor: MUETSCHELE ULRICH DIPL ING
IPC: B23B45/16
Filed: 1982-08-27
Abstract: The powered hand tool (2) has a screwed-together housing, a percussion piston (27), a tool receptacle (49) for a tool, and a dolly (34) between the tool receptacle and the percussion piston, having a striking surface (41) directed in the percussion transmission direction. A further striking surface (48) arranged on a screwed-on housing part (5) is directed towards this striking surface (41). Between the striking surfaces (41, 48), two striking rings (52, 53) are arranged one behind the other in such a way as to be movable individually. If the tool meets with no resistance, the kinetic energy of the dolly (34) is repeatedly redistributed between the dolly (34), the first striking ring and the second striking ring. As a result of the many blows occurring in the process, a great deal of kinetic energy is lost in the form of heat, so that the dolly (34), after an idle stroke, no longer comes within the range of the percussion piston (27). In addition, only a portion of the kinetic energy of the dolly (34) acts on the fixed striking surface (48), so that screws (44) which hold the housing part (5) on the powered hand tool (2) are not slackened. <IMAGE>
