Title: Hydraulic mine striding support prop. regulation - has fluid flowing to return valve controlling supply to pressure chamber
Inventor: BUELL HANS ING GRAD
IPC: E21D23/16
Filed: 1980-04-22
Abstract: Three-to-two-way valves alternately acting on the two piston sides, with fluid from a high-pressure load, and connecting the activated side to a return lead, are incorporated in controls for a hydraulic prop in a striding support system in a mine. Supply of pressure fluid from the high-pressure lead (P) to the pressure chamber in the prop (1) is regulated by the fluid running out from the pressure-limiting valve (10) to the return lead (R) . The latter valve is pref. set for a lower pressure than the intended pressure in the high-pressure lead. Each prop can be precisely set with the set pressure of the allotted pressure-limiting valve, regardless of the duration of activation of the setting valve.

Title: Doppler radar monitor for instantaneous vehicular speed measurement - uses known length of track as reference distance for comparison of set speed with actual speed
Inventor: MUELLER HANS-JOACHIM ING GRAD
IPC: G01S13/60
Filed: 1980-07-04
Abstract: A controller (2) assisted by a Doppler unit (1) ascertains the instantaneous speed at a rail brake (3) and compares it with the set rated speed and determines control order for the brake (3) - on the basis of the values obtained. The brake can then be applied with the correct strength to the wagon (4) or group of wagons. Sensors (E,A) are necessary either side of the brake (3) to detect the presence of a wagon in the vicinity. The doppler impulses are summed in a monitoring unit (5) when an axle passes from the first sensor (E) to the next (A). The sum of the counted impulses then represents the distance (Lref) between the two sensors (E,A), which are firmly screwed to the rail, with the very accurately determined distance between them fixed to the nearest millimetre. This distance (Lref) is the length which is fed to the monitor (5) and used as a comparison with the Doppler count. This measuring method is very exact and allows a fault condition to be indicated should the Doppler count be upset by component faults.

Title: Roll-type capacitors made from rolled alternate layers - of metallised and non-metallised plastics foil cut into capacitor lengths
Inventor: PETRICK PAUL DR
IPC: H01G4/32
Filed: 1980-10-13
Abstract: Multiple roll-type capacitors are made by cutting lengths from a rod-shaped winding or coil, and fitting contact plates to the cut ends. This initial winding or coil is composed of a plastics foil, with metallised strips on its opposite faces, all running parallel to the direction of rolling and separated from one another by insulating gaps; the centres of the strips on one side are opposite the gaps between strips on the opposite side. Secondly, a plastics foil with no metallised surfaces, cut into parallel strips also and laid with gaps between them is rolled up together with the foil having the metallized strips so that the gaps between the unmetallized foil correspond with the centres of the adjacent metallized strips and the resultant roll-type capacitor assembly is composed of alternate layers of the metallized and unmetallized foils. This is then cut to length as above. Preferably, the non-metallized strips are narrower by 0.1-2 mm than the metallized strips. Preferred material for the plastics foils include polyester, polycarbonate, polypropylene or polysulphone.

Title: Method for transmitting digitised sound signals in the horizontal blanking interval of a video signal
Inventor: HESSENMUELLER HORST DIPL ING
IPC: H04N7/085
Filed: 1981-02-02
Abstract: The invention relates to an improvement of known methods for transmitting digitised sound signals in the horizontal blanking interval of a video signal, in which the bit flow must have a fixed phase relationship to the line frequency fZ. According to the invention, sampling initially occurs at the internationally provided sampling frequency f1 = 32 kHz, which is independent of the line frequency, for reasons of a studio, transmission and receiver technique which is uniform for digital sound broadcasting and television sound transmission. The bit flow produced is then enlarged, by addition, known per se, of a differential flow  DELTA phi  <<  phi 1, containing the synchronisation and clock matching information and the clock matching bit for a positive clock matching method, to a bit flow  phi 2, the bit repetition rate f2 of which finally has the required fixed phase relationship to the line frequency f2 DIVIDED fZ = n (n = number of bits to be transmitted in the horizontal blanking interval) (Figures 1 and 2). In an illustrative embodiment for transmitting two sound signals in the horizontal blanking interval with a bit flow  phi 1 of 2 x 338 kbit/s = 676 kbit/s, the bit flow  phi 2, increased from 1006 bits/frame to 1024 bits/frame by 12 clock matching synchronisation bits k, 5 bits for signalling the clock matching s and by one bit st, of 687.5 kbit/s with  n = f2 DIVIDED fZ = 687.5 DIVIDED 15.625 = 44 bits  in the horizontal blanking interval. <IMAGE>

Title: Vaporising oil burner
Inventor: SCHILLING JUERGEN DIPL ING
IPC: F23D11/00
Filed: 1981-01-31
Abstract: The present invention relates to a vaporising oil burner with an oil-supply conduit, with an air-supply conduit provided with a blower, and with a vaporisation pot which can be rotated by an engine and to which a combustion space is connected. In such vaporising burners, there is the disadvantage that the outer casing surface of the vaporisation pot often cannot be fully utilised for vaporisation. Furthermore, there is the disadvantage that there is often the possibility of the condensation of vaporised oil on cold parts of the housing. The object on which the present invention is based is, therefore, to improve the position of the vaporisation pot decisively, in order to obtain more favourable vaporisation conditions and, at the same time, to prevent condensation of already vaporised oil. Furthermore, to prevent pre-oxidation, only combustion products are to be used for vaporisation. This object is achieved, according to the invention, in that the vaporisation pot is of cylindrical shape and its orifice faces the combustion space, and in that the outer casing of the vaporisation pot is thermally insulated relative to the air supply by means of an annular space.
Patent DE-3123915-A1 (DE)
Title: Appliance for sucking off and pumping off liquid manure and ground and percolating water out of a stable-manure distribution apparatus embedded in an open concrete pit
Inventor: ZEISLER JOHANN
IPC: A01C3/02
Filed: 1981-06-16
Abstract: An appliance for sucking off and pumping off liquid manure and ground and percolating water out of an upwardly open concrete pit embedded in the ground is proposed. The sucking off and pumping off take place by means of a suction pump which is effective in a container which receives an inflow and return-flow line leading to the stable. It is thereby to be possible, at any time, to suck off, by means of the suction pump provided for manure distribution, water which has accumulated in the upwardly open concrete pit above a stable-manure distribution apparatus embedded in the latter. It is to be possible, at the same time, to pump off ground water rising during the erection of the concrete pit and during the sinking of the stable-manure distribution apparatus. For this purpose, according to the invention, there is arranged in the surface covering the container (10) at the top a drainage valve (14) which opens into the container interior and which is normally held in the closed position by a compression spring (19) and, in the open position, opens an orifice (16) provided in the container wall. The drainage valve is preferably designed as a ball valve, the spherical valve body (15) closing the orifice (16) from inside the container (10). It has been shown that a pumping off of water is possible when, with the return-flow line shut off, the inflow line has previously been pumped empty. The water which flows or has penetrated into the container after the opening of the drainage valve is then conveyed upwards, when the suction pump is started up, via the delivery line of the latter. <IMAGE>

Title: Pass photo cutter
Inventor: BODENTIEN KLAUS
IPC: G03D15/04
Filed: 1981-06-23
Abstract: The invention relates to a pass photo cutter which is to be manually operated and makes it possible to cut photos in strips or blocks of paper or individual photos to the correct dimensions on all sides simultaneously, and is especially intended for use by all offices which have to produce large numbers of passes with photographs of all kinds. The aim of the invention is to make it possible for photos on paper for passes of all kinds to be cut out on all sides in a single operation instead of being cut with scissors or other cutting tools on each side individually. The current state of the art offers various ways of achieving this. Scissors and other cutting tools (Patent 11b11, 1761522) are most frequently used in the offices and specialist photographic shops in question. These methods of cutting pass photos to the prescribed dimensions are to some extent defective from every point of view. Cutting each side of the photos individually is very time-consuming and a certain degree of inaccuracy can hardly be avoided. The object of the invention is to reduce to a minimum the time required to cut out the photos.

Title: Hydraulic control device for the load-independent control of a double-acting servo motor
Inventor: OLBRICH GOTTFRIED
IPC: F15B11/044
Filed: 1981-10-08
Abstract: The invention proposes a hydraulic control device (10) for the load-independent control of a double-acting servo motor (30), on which retarding or driving loads can act in both directions of movement. The control device (10) has a flow control valve (12) which is inserted between directional control valve (11) and servo motor (30) and the regulating slide (36) of which valve which is centred by springs (71, 72), is loaded by the pressure difference of a throttling location (33) which is formed by the control slide (29) of the directional control valve (11) and is situated in the flow of pressure medium flowing from the servo motor (30) to the tank (17). In the case of retarding loads, the regulating slide (36) acts with its two control edges (67) for each servo motor connection (59, 61) as a three-way flow regulator with inflow regulation and, in the case of driving loads, acts with its first control edges (65) as an outflow regulator. In addition to the possibility of different settings of the pressure medium flows for both connections (59, 61), different pressure settings are possible by virtue of pressure-limiting valves (68, 69) arranged in the regulating slide (36) and exercising pilot control. <IMAGE>
