Title: Foot hold for roofs which are covered by tiles, slates or panels
Inventor: GIELISSEN HANS
IPC: E04D13/12
Filed: 1981-04-06
Abstract: The invention relates to a foot hold for roofs which are covered by tiles, slates or panels. The foot-hold element can be fastened in different positions on an arcuate carrier, which is upright in the installed position, such that the foot-hold surface is horizontal despite the inclination of the roof. Via a flat through-passage piece, guided between two overlapping tiles or panels, and a transversely running connecting piece, the carrier is connected to a plate which can be fastened directly on a rafter or a purlin such that the carrier has sufficient side stability. For adaptation to various distances between rafter or purlin and underside of the upper plate, the connecting piece can be adjusted in terms of length. In particular, it comprises two overlapping parts which can be adjustably connected to each other by screw-bolts. <IMAGE>

Title: Low-noise flow control valve
Inventor: PAWELZIK MANFRED ING GRAD
IPC: F16K3/08
Filed: 1981-07-14
Abstract: The invention relates to a flow control valve with a valve seat disc held in a fixed manner in the housing and a valve regulating disc which can be rotated by means of a holding member. To reduce the noise associated with flow, pins are integrally formed on the face facing the valve regulating disc and these pins partially fill a free space existing between the holding member and the valve regulating disc. In this free space, the medium, which is fed in radially, undergoes a radial change of direction and discharge from the valve. For optimum guidance of the water, the pins at the outer edge region of the passage opening extend as far as the valve regulating disc or reach into the passage opening, and are designed so as to shorten continuously towards the opposite side of the holding member, giving a grid surface which is oblique or curved in relation to the centre line.

Title: Clamping device for hollow, unstable workpieces for machining them by turning, cylindrical grinding, milling or the like
Inventor: SCHRAMM HEINRICH
IPC: B23B31/40
Filed: 1981-09-03
Abstract: Clamping device for thin-walled or, on account of their material, unstable, at least partly hollow workpieces. In order to be able to firmly clamp such workpieces in position without the risk of deformation in such a way that they can be satisfactorily machined by turning, cylindrical grinding, milling or the like, the clamping device is designed in such a way that it has an inner and an outer clamping element as well as an actuating element for each of the clamping elements. At its periphery, the inner clamping element has an inner clamping area which is concentric to the axis of the clamping device and can be expanded in the radial direction. The outer clamping element overlaps the inner clamping area and has opposite the latter an outer clamping area which is likewise concentric to the axis of the clamping device and can be reduced in the radial direction. The actuating elements are displaceable in the axial direction relative to the clamping elements allocated to them and in each case have a taper against which a taper connected to the respective clamping element bears. Finally, the actuating elements can be adjusted relative to one another in the axial direction.

Title: Threshold circuit without hysteresis
Inventor: FRICKE HANS PROF DR ING
IPC: B61L1/18
Filed: 1981-09-05
Abstract: This threshold circuit has two active operating states and one passive failure state. It can be used for determining the position of an alternating voltage to be evaluated, for example a track voltage in a track circuit, with respect to a reference voltage, any disturbances (for example due to component failure) being indicated by the passive state which can be distinguished from the two operating states. The invention makes use of the finding that the instantaneous frequency of an aggregate voltage produced from the addition of two voltages of different frequencies is a function of the amplitude ratio of the added voltages. Accordingly, the threshold circuit according to the invention consists of an adding circuit (AD) in which a reference voltage (U2) with a frequency (f2) which is different from the frequency (f1) of the voltage (U1) to be evaluated is added to the voltage to be evaluated and of an evaluating circuit (AWS) for detecting the instantaneous frequency (f1) of the aggregate voltage (U1) and for comparing this instantaneous frequency with a nominal value. Various variants of the evaluating circuit are the subject-matter of the subclaims. <IMAGE>

Patent DE-3203927-A1 (DE)
Title: Heating and air-conditioning device for the passenger compartment of a motor vehicle
Inventor: KOSSIRA KLAUS
IPC: B60H1/00
Filed: 1982-02-05
Abstract: The radiator of the internal combustion engine of a motor vehicle is divided into two sections which can be connected via a thermostat valve, of which sections one continuously has cooling fluid flowing through it and serves both as a heat exchanger and as a radiator and the other section serves only as a radiator. The radiator is arranged between the internal combustion engine and the passenger compartment so that a feed line and a return line is necessary for the connection to the internal combustion engine. The section of the radiator which serves as a heat exchanger is connected here via an air guidance channel to the passenger compartment. The incoming air is directed via an air feed channel both via the heat exchanger and, in accordance with the position of baffles, optionally either into the passenger compartment or into the open air, and into the passenger compartment by passing the heat exchanger. The air flowing through the other section is, if appropriate, directed into the open air with the air flowing through the heat exchanger via a further air guidance channel containing a cooling air ventilator.

Title: Arrangement and process to produce hot bottom blast for a blast furnace
Inventor: BRICMONT FRANCIS H
IPC: C21B9/00
Filed: 1982-02-15
Abstract: The invention relates to an arrangement and a process to heat the bottom blast in a blast furnace. In contrast to the blast heaters hitherto used here in the form of vertical towers in which the heating up of the storage unit and the heating of the blast gases took place, regenerators (10,11,12) are used which are acted on horizontally and surrounded on all sides with a metallic cladding; the horizontal flow through their storage bodies (32) is in one direction in the gas (on gas) stage, and in the opposite direction in the blowing stage (on blast). A plurality of regenerators (10,11,12), which can be switched in parallel, are present; recuperators (46,47,48), which can likewise be switched in parallel, provide for heat exchange between the regenerator exhaust gases and the bottom blast to be preheated. Lower exhaust gas temperatures, and higher temperatures for the bottom blast, are achieved. <IMAGE>

Title: Front power lift with power take-off shaft for tractors
Inventor: ALBERSINGER GEORG
IPC: B62D49/02
Filed: 1982-03-18
Abstract: The front power lift serves for the attachment of implements to the front side of a tractor, the power take-off shaft being intended for driving the implements. The particular feature of the front power lift consists in the arrangement of the lifting cylinders (7), characterised in that they are accommodated in a virtually vertical position within the engine cowling and are connected by a crossmember (8). This crossmember (8) is connected via tensile members (9) to the bottom links (2) of the three-point hitch. The special feature of the power take-off shaft is characterised in that a planetary gear unit (26) is used which is likewise accommodated within the engine cowling and is driven directly by the engine crankshaft (16). The planetary gear unit (26) on the one hand ensures the correct conversion of the engine speed and on the other hand effects the necessary reversal in the direction of rotation. The planetary gear unit (26) is in addition connected to a starting clutch (20). <IMAGE>

Title: Emptying device for sacks and bags
Inventor: SCHMITZ JOACHIM ING GRAD
IPC: B65B69/00
Filed: 1982-03-30
Abstract: The emptying device is used for mechanically opening sacks and bags filled with a bulk material, in particular when the number of sacks or bags to be opened is very large or when it is unreasonable to empty the bulk material by hand, due to excessive dust formation for instance, or is inadmissible due to the properties of the bulk material. The emptying device (10) has a funnel (20) as the supplying device, through which the sacks or bags can be fed in a largely disordered manner. Situated at the lower end of the funnel (20) are either a cutter grate or preferably two cutter grates (27, 28) which are each equipped with a group of cutters (35, 36). The cutter grates (27 and 28) are movably guided, by means of oscillating connecting rods (29', 30') for instance, and are set in oscillating movement by means of a drive having a crank mechanism or eccentric mechanism (45, 45'). In the case of two cutter grates (27, 28), the cutters (35, 36) of both grates are each closely adjacent to one another in pairs. Furthermore, the two grates (27, 28) are then driven in opposite directions. The cutting edge of the cutters (35, 36) can be elongated and of the same shape or alternatively toothed, or it can run in the shape of a wave or a triangle. In the last-mentioned cases, the cutters (35, 36) can be composed of shorter individual blades (39, 40) which are fixed to supporting strips (38). <IMAGE>

Title: Recording-tape cassette safety system
Inventor: BEINDORFF CHRISTOPH
IPC: G06K5/00
Filed: 1982-04-14
Abstract: The object on which the present invention is based is to provide a new cassette safety system which is intended to protect cassette manufacturers from imitations by third parties. The first solution according to the invention for this object is achieved by affixing the legally protected signature sign of the cassette manufacturer on the cassette itself. The advantage of this invention in comparison with conventional cassettes is that the cassette and the protected signature sign affixed to it are optically and electronically sensed identically by the respective machine mechanically and electronically, in order to clear the respective functions of the machine by means of a sealed monitoring and switching system. Cassettes which do not have affixed to them the signature sign in the prescribed patent claim are not accepted by the respective machines and are therefore useless.
