Title: Firing regulator for a solid-fuel heating boiler
Inventor: GOEBEL WERNER
IPC: F23N3/04
Filed: 1981-02-12
Abstract: The invention relates to a firing regulator of a heating boiler, in particular a heating boiler for solid fuels, which can be operated in combination with an oil-fired or gas-fired boiler. The air dampers in front of the "poke holes" for the supply of combustion air are moved, by means of known firing regulators, in dependence on the boiler water temperature. An air damper located in the open position when the solid-fuel boiler is cold leads to undesired heat losses in a heating system in which a solid-fuel boiler is operated in combination with an oil-fired or gas-fired boiler which takes over the heating operation when the solid-fuel boiler is cold. According to the invention, a heating member, preferably an electric heating coil, is assigned to the firing regulator, moving the air damper, which heating coil can be switched on and off in dependence on the operation of the oil firing or gas firing. The heating member simulates, for the firing regulator when the solid-fuel boiler is cold and the oil or gas firing is switched on, a boiler water temperature of the solid-fuel boiler which causes said regulator to close the air damper. As a result, the undesired heat losses are avoided.
Patent DE-3105710-A1 (DE)
Title: Adhesive bolt
Inventor: QUANTE HEINRICH
IPC: E21D11/15
Filed: 1981-02-17
Abstract: In mining and in the building industry the need arises again and again of providing temporary or definitive fastening points. Underground, this problem arises particularly where mesh wire or the like is to be fastened by rock bolts on the rock or on similar surfaces. For this purpose, use is made of an adhesive bolt which comprises a convexly curved bolt plate, an adhesive-supply tube, set down in the trough of a syncline, and a wedge which can be driven into the supply tube. The quantity of adhesive to be supplied is pressed via the wedge, into the convexly curved bolt plate, with the result that bolt plate and rock are adhesively bonded to one another. In order to improve the adhesive action and to fix the quantity of adhesive within the convexly curved bolt plate, a sponge-like ring is placed on the outer border and the interior of the bolt plate is filled with glass-fibre fabric or rock wool. The hollow plug is pressed, for example via a pressure-medium cartridge, air, water, hydraulic fluid or CO2, against the glass ampoule containing the plastic adhesive, with the result that said ampoule bursts and the adhesive penetrates into the bolt plate. <IMAGE>

Title: Guillotine knife, especially of a circular or curved design, for foodstuffs, such as meat, bread or the like
Inventor: REMMERT JOHANNES
IPC: B26D1/00
Filed: 1981-05-07
Abstract: Guillotine knife, especially of a circular or curved design, for foodstuffs such as meat, bread or the like. In the case of a guillotine knife which is circular or curved, precutting teeth (11) and after-cutting teeth (111) are arranged. The precutting teeth (11) are larger than and/or project somewhat further than the after-cutting teeth (111). The precutting teeth cut an initial slit into the material and the material, which may spring or swell back, is then recut by the after-cutting teeth (111). In this process, it is possible to place one after-cutting tooth (111) behind each precutting tooth (11) in each case. It is, however, also possible to assign a plurality of after-cutting teeth to one precutting tooth. Precutting teeth and after-cutting teeth may be differently shaped, but they may also be of the same shape. It is advantageous to make the after-cutting teeth continuously decrease in size moving in the opposite direction to the cutting direction. <IMAGE>

Patent DE-3128434-A1 (DE)
Title: Swivel joint with adjustable latching
IPC: F16C11/10
Filed: 1981-07-18
Abstract: Each of the two housing halves (1.1, 1.2) coupled together rotatably by an axial connecting device (5-7) is designed with a connection end for holding a supporting arm (bracket) or the like and means (14, 18) to hold braking and latching elements (15, 21, 22, 25). For this purpose, one (1.1) of the housing halves contains a braking and latching plate (15) supported perpendicular to the axis (A) of rotation by a supporting zone (14), while the other (1.2) housing half contains braking and latching elements (21, 22, 25) supported in holes (19) in a block zone (18) lying opposite the latching plate (15). These elements include friction pins (21), one end face of which is designed as a flat braking surface (23) and is pressed by spring pressure against the braking and latching plate (15) in the first housing half (1.1), and the other end face of which is designed with a location recess (24) for a ball (25) which engages in associated latching recesses (26) in the latching plate (15). The housing halves (1.1, 1.2) do not themselves have any parts for latching and braking engagement with one another but serve only as holding elements for easily replaced friction and latching elements, by means of the relative association of which both the disengagement and the actuating torque can be easily preselected. <IMAGE>
Patent DE-3129319-A1 (DE)
Title: Production of cooking utensils with a prestressed base of constant flatness
Inventor: PFAB LOTHAR DIPL ING
IPC: B21D51/22
Filed: 1981-07-24
Abstract: The invention relates to a method and a device for the production of pots and pans with a radially prestressed base in which no compressive stresses occur when they are heated during use, such compressive stresses leading to the bulging of the base. The invention is intended to make a decisive improvement in the service properties of pots and pans by ensuring that their base maintains a constant flatness and does not bulge when heated. According to the invention, this is achieved if tensile stresses directed primarily towards the centre of the base are introduced into it. Upon heating, thermal expansion leads to a reduction in these tensile stresses dependent on the temperature, without the occurrence of compressive stresses. For this purpose, one or more zones of the base are heated briefly to temperatures above the high-temperature limit of elasticity of the respective material, expansion being prevented by the unheated areas and the corresponding constraint. As a result, the heated areas are compressed plastically and their shrinkage upon cooling gives rise to the expected tensile stresses.

Title: Device for dispensing cotton-wool balls
Inventor: LOOS FRED
IPC: A45D44/00
Filed: 1981-09-08
Abstract: The invention relates to a device for dispensing cotton-wool balls, having a two-part receiving container for the cotton-wool balls, one part of which is provided with a passage opening which is partially closed by webs of essentially circular cross-section and through which the cotton-wool balls are pressed by means of a relative movement of the two parts of the receiving container for the purpose of removal. The invention is intended to provide a device for dispensing cotton-wool balls, which facilitates refilling, requires less constructional expenditure, and exerts an even pressure on the cotton-wool balls. Additionally, during use of the device, the pressure on the cotton-wool balls is to be able to be increased to any desired extent, passage of the cotton-wool balls through the passage opening is to be facilitated, tearing of the cotton-wool balls and felting thereof are to be prevented and the operability is generally to be facilitated. This is achieved in that the relative movement of the two parts of the receiving container is achieved by gravity, and the diameter of the webs corresponds essentially to the radius of the cotton-wool balls. <IMAGE>

Title: Control device for electrically triggering a water feed
Inventor: HANSLIN RUDOLF DIPL ING
IPC: H03K17/96
Filed: 1981-10-10
Abstract: For optionally emitting different quantities of flushing water by means of an electromagnetically operable flushing tank valve, a capacitive sensor key (11), fed with pulses, having two key panels (12, 12') is provided. An evaluating circuit (9) checks whether a pulse deformation has occurred due to partial capacitive bypassing of the pulses due to a short touching of one of the key panels (12, 12') and then triggers an adjustable timing element (18, 18'), associated with the relevant key panel (12, 12') in a control circuit (10). Triggering of the timing element (18, 18') excites the coil (19) of a relay, the relay contact (20) of which switches on the magnetic coil (21) of the flushing tank valve. The relay coil (19) remains excited until the delay determined by the timing element (18, 18') has elapsed so that flushing water flows during this time. As a result, different, continuously presettable flushing times can be achieved by simple and harmless touching of corresponding key panels. <IMAGE>

Inventor: OSTERHAGEN GERHARD
IPC: B29D23/00
Filed: 1981-10-10
Abstract: A process for the continuous manufacture of a closable pipe slotted in the longitudinal direction which is made from a sheet of a thermoplastic foam material involves shaping the sheet in the heated thermoelastic and/or thermoplastic state at right angles to its longitudinal direction into a pipe cross section, and applying the strips of a closure, especially a slide fastener of a thermoplastic synthetic resin, to the mutually facing longitudinal edges of the pipe slot by means of welding, heat-sealing, cementing, or the like. The closure strips, prior to being joined to the shaped, still heated foam pipe, are elongated by the effect of tensile force to the same extent as the foam pipe shrinks during cooling after application of the closure to provide a straight pipe or sheath like structure with a closure means.

Title: Semiconductor device comprising pressure-contactable semiconductor bodies
Inventor: KIEFER JAKOB
IPC: H01L25/07
Filed: 1981-10-27
Abstract: If a pressure-contactable semiconductor device containing semiconductor bodies (2,3) is to be mounted on a heat sink (17), a defined pressure and a flat base are necessary to achieve an optimum heat transfer. This is attained if the pressure-absorbing parts (9, 10; 11, 12) of the semiconductor bodies project out of the housing at the top and terminate at least flushly with the bottom section (14) of the housing at the bottom. Between the semiconductor bodies (2, 3) there is a central fixing hole (15). The device is held by means of a central screw (20) which presses a spring (19) against the parts projecting at the top. This establishes the internal contact pressure and achieves a good thermal contact with the heat sink. <IMAGE>

Title: Continuously working winning machine for fluent solid material and natural raw materials
Inventor: WETZEL ARNO DIPL ING
IPC: E21C47/02
Filed: 1981-10-31
Abstract: The invention relates to a winning machine for fluent solid material and natural raw materials which can be used as an excavator, stockpiling and reclaiming machine, loading and unloading machine for large transport units (e.g. ships) and the like. The aim of the invention is to increase the delivery capacity and the excavation thickness of winning machines and to reduce the machine cost and the energy cost. On machines with preferably plough-like digging and loading members arranged on revolving traction means and continuous conveyors arranged in the same way, the object is to design the digging member in such a way that reliable transfer to the continuous conveyor, its automatic emptying as well as support on independent travelling gear or suspension on a supporting structure arranged above it are possible. According to the invention, this is achieved by the arrangement of a helically curved baffle plate on the digging member, the guidance of the traction means on a guide frame vertically adjustable relative to the supporting framework, the arrangement of a continuous conveyor, preferably a carrying-chain conveyor of symmetrical design, in the vertical longitudinal centre plane of the supporting framework, its revolving length projecting beyond the engagement length of the digging members at both ends, and the digging and loading members having a sufficiently large speed difference from the continuous conveyor. The supporting framework can therefore be supported on independent travelling gear above, below or on the slope or can be hung on an excavator construction and can also be of multi-section construction.

Patent DE-3203286-A1 (DE)
Title: Process for the preparation of cyclohexanone
Inventor: TAKEHIRA KATSUOMI
IPC: C07C45/34
Filed: 1982-02-01
Abstract: The invention provides an effective process for the preparation of cyclohexanone by liquid-phase oxidation of cyclohexene in the presence of a catalyst system. The degree of conversion of cyclohexene and the yield of cyclohexanone are unexpectedly increased if the reaction mixture brought into contact with oxygen or air contains a limited amount of an aliphatic alcohol having 2 to 10 carbon atoms in the molecule, such as, for example, ethyl alcohol, and the catalyst system is composed of a palladium compound, for example PdCl2, and at least one co-catalyst component in the form of a copper compound or an iron compound such as CuCl2 or FeCl3. The benzene or cyclohexane added to the reaction mixture was found to have no adverse effects or even gave improved results in the reaction and provide further advantages for the process, in which the starting cyclohexane need not be purified and can be used as prepared by partial hydrogenation of benzene or partial dehydrogenation of cyclohexane.

Title: Power unit as a working member, e.g. for presses for shaping and compacting, for rams, etc.
Inventor: KNAEBEL HORST ING GRAD
IPC: E02D7/10
Filed: 1982-03-27
Abstract: In a power unit as a working member, e.g. for presses for shaping and compacting, for rams, etc., with a working piston (8) movable in a cylinder (7) and having a transmission member (9), the primary cylinder space (7a) delivering the working power is continuously under the pressure of an energy accumulator (18), while the secondary cylinder space (7b) is filled with pressure medium bringing about the equilibrium of forces before the start of work. A first auxiliary piston (33) of large area, to which a second auxiliary piston (24) defining a working space (23a) and projecting with a piston rod (27) into the first auxiliary piston (33) is allocated, subdivides a further cylinder space (23) into a secondary space (23b), receiving the expansion volume of the secondary cylinder space (7b) in a restrictor-free manner, and into a restoring space (23a) and separates a control space (38), which can be pressure-relieved, at the end face, from the secondary space (23b). Via a valve arrangement (3, 4), the control space (38) and the working space (23a) can be relieved and can be loaded with pressure, and the two auxiliary pistons (24, 33) assume their basic position. To obtain a short overall length of the auxiliary-piston unit, to avoid energy losses from the first auxiliary piston (33) and to ensure reliable sealing of the same at the end face, the second auxiliary piston (24) is guided in the cylinder space (23) of the first auxiliary piston (33) and its piston rod (27) projects in a sealing manner through the first auxiliary piston (33) and the control space (38) into a hollow space (29) which can be loaded and relieved via the valve arrangement (3, 4). <IMAGE>
