Title: Device for measuring a throating
Inventor: SCHROIFF EDGAR
IPC: G01B5/213
Filed: 1981-08-12
Abstract: Bowling (skittle) alleys, in particular scissor-shaped bowling alleys, have throatings which are difficult to check. The difficulty arises from the continuously changing width of the throating in conjunction with a constant depth of throating. As a result the radius of curvature depends on the length of the alley. It is now possible to overcome the difficulties in measuring throatings by using a device in accordance with the present invention. The device consists of a rigid support rail which overspans the throating and has a leaf-shaped spring which is fastened at a distance below and parallel to the support rail by means of displaceable retaining elements. Arranged on the underside of the support rail and in the middle between the retaining elements is a rigidly attached spacing element whose thickness is larger by the depth of the throating than the distance of the top side of the spring from the underside of the support rail at the retaining elements.

Title: Process and plant for treating dirty water
Inventor: BAUR PETER
IPC: B01D1/28
Filed: 1982-04-21
Abstract: A process and a plant are described for treating dirty water, dirty water being taken to mean both seawater and brackish water and also waste water (effluent), in particular industrial waste water. According to the invention, the dirty water is evaporated, the heat contained in the steam and in the condensate being recovered by an at least two-stage heat exchange with the dirty water for evaporation thereof. In addition, compression of the vapour obtained from the dirty water takes place, in order by this means to feed the thermal energy recovered to the process using electrical energy, that is the driving energy for the compressor. According to the invention in this case, apart from the start-up time in normal operation, virtually the only energy employed is that supplied for vapour compression, which is made possible by continuously circulating a considerable quantity of liquid in an evaporator circuit in the water treatment plant according to the invention, to completely recover at least the heat of condensation from the second heat exchanger.

The baffle surfaces are formed as vertical cones, so that deposited dust can be extracted by an extraction device.
Patent DE-3220553-A1 (DE)
Title: Sawtooth generator
Inventor: BRAJDER ANTONIO DIPL ING
IPC: H03K4/56
Filed: 1982-06-01
Abstract: The invention relates to a sawtooth generator having an integrator (1), the output of which is connected to a first input of an adding element (3e, 3f, 4a). The output of the adding element is connected to the input of a controller (3) having integrator characteristics, the output of which is connected to the input of the integrator (1). The output of the integrator (1) is also connected to one input of a comparator (4), at the comparison input of which a reference voltage (Uref3) is present, the amount of which is above a nominal crest value of the sawtooth voltage. The output of the comparator (4) is also connected via a diode (4b) to one input of the adding element (3e, 3f, 4a). In addition, a reference voltage (Uref1) is present at a further input of this adding element. In this circuit, the input voltage of the integrator (1) is reduced with a small time constant when the amount of its output voltage exceeds the third reference voltage (Uref3). As a result, the output voltage of the sawtooth generator is very rapidly brought close to its nominal value where the controller (3) then takes over fine control. <IMAGE>

Title: Process and apparatus for volume reduction of organic waste of low radioactivity
IPC: C10B53/00
Filed: 1982-06-28
Abstract: According to the invention, the low-level radioactive wastes such as fabrics, shoes, wood shavings, waste paper and plastic wastes produced in nuclear power stations, large clinics and the like are subjected to low-temperature carbonisation at 450-600 DEG C with exclusion of air and constant circulation. The radioactive substances remain in the solid low-temperature carbonisation residues and a reduction in volume to less than a tenth of the original solid volume occurs. The dust-free low-temperature carbonisation gases are cracked at approximately 1000-1200 DEG C. The mixed gas flows through a 1000-1200 DEG C reaction zone of a coke-containing fixed bed. The low residual fractions of active substances and heavy metal compounds are bound to the surfaces of the hot coke particles. The cracked gas produced is then cooled to below the condensation point and is scrubbed with the resulting condensate containing active carbon particles. The clean gas is burnt as a fuel for the low-temperature carbonisation of the wastes. <IMAGE>

Abstract: A device for forming and delivering counted packages consisting of a number of flat individual products made of paper, cellulose wadding or the like. The individual products (3) are fed by means of a conveyor-belt system (1) to a stacking device (4) which has an ejection device (8) arranged above the conveyor-belt system and a collecting track (20) arranged below the conveyor-belt system. On the collecting track (20), the individual products are discharged as a continuous stack (7). To ensure that predetermined individual products (13) in the stack (7) are displaced, use is made of a device (19) which makes it possible for the conveyor belt speed to be changed to a higher or lower value for a limited period of time and for this speed to be returned to its starting value. Said device (19) has a driving belt (11) which is guided round a drive shaft (21) of the conveyor-belt system (1) and, in succession, round a first deflection roller (16a), a driven roller (15) connected to the driving device (22), and a second deflection roller (16b). The two deflection rollers (16a, 16b) and the driven roller (15) are arranged on a swivel plate (14) which can be swivelled about the axis of rotation of the driven roller (15). The swivel plate (14) is caused to swivel by means of an actuating cylinder (17). During the swivelling operation, the deflection rollers (16a, 16b) produce an additional movement of the driving belt which is added to or subtracted from the rotational movement. <IMAGE>

Title: Method for fixing a hollow dowel
Inventor: JOLY GUENTER
IPC: F16B13/14
Filed: 1983-06-21
Abstract: The invention relates to a method for fixing a dowel in a structure, the hollow shank of which is inserted with a first portion into a drill-hole and is secured there by a curable filling compound, and to the second portion, projecting out of the drill-hole, of which are fixed parts, in particular wall-covering parts, which are to be held. An annular part for the outer closure of the drill-hole is attached externally to the shank. Before insertion of the dowel, filling compound is introduced into the drill-hole. When driving the dowel into the drill-hole as far as the specified seat, pressure is exerted on the filling compound by the annular part, the collar and/or the dowel-shank volume, causing the excess filling compound to pass outwards through the shank interior.
