Patent DE-3220107-A1 (DE)
Title: Process and apparatus for the production of substantially anhydrous industrial ethanol
Inventor: BRANDT HANS-WALTER DR DIPL CHE
IPC: B01D1/26
Filed: 1982-05-28
Abstract: Substantially anhydrous industrial ethanol can be obtained from dilute, aqueous ethanol by preconcentration by distillation and substantial elimination of remaining water by extractive distillation. The preconcentration is carried out in a multistage manner up to a concentration of 70 to 92% by weight of ethanol and, possibly, organic congeners in the preconcentrate. Each of the preconcentration stages is performed at a lower pressure and at a lower temperature than the preceding stage. The energy required for this is supplied solely to the first preconcentration stage. The dilute aqueous ethanol used is, for example, fermentation alcohol (mash), the organic congeners occurring being the accompanying fusel oils. When mash is used, the spent wash occurring as the bottom product from the preconcentration can be fed to a spent wash evaporation. The steam occurring here can be utilised for the direct steam heating of the first stage of the preconcentration.

Title: Suction arm for sucking out smoke and gases
Inventor: HOFFMANN ERNST DIPL ING
IPC: B08B15/00
Filed: 1982-07-10
Abstract: The known suction arms are all difficult to handle. A comparatively large effort is required to adjust them in a spatially stable manner. This is due to the helical torsion springs between the rod sections. Their elastic force does not remain constant over the range of the springs. This deficiency is particularly evident in cases where the position of the suction hood has to be continuously adjusted. According to the invention, the rod longitudinal sections (20, 21) are interconnected by means of a pneumatic spring (32) and connected to a bracket (19) by means of a pneumatic spring (28). The flexible suction hose (4) is arranged above the articulated rod (5). The elastic force of the pneumatic springs (28, 32) remains constant over the entire range of the springs. They can be coordinated such that only small forces need to be applied to adjust the suction arm (1), taking into account the remaining adjusting mechanism. Moreover, perfect positional stability is provided. If necessary, friction linings can be incorporated into the connecting joints (22, 23) between the rod longitudinal sections (20, 21) and between the bracket (19). <IMAGE>

Title: Bandsaw with rotatable supporting table
Inventor: KEMPF WERNER
IPC: B23D55/08
Filed: 1982-08-14
Abstract: The invention relates to a bandsaw with continuously variable saw deflection. A hitherto unused clearance space is thereby developed without adversely shortening the material pass, as is the case with a rigid deflection. The invention is mainly suitable for the handyman. For the first time it enables the handyman to cut off boards, tubes and profiled strips, of any sectional length, at right angles. According to the invention the supporting table combines the rotary movement of the table with the deflection function. In addition, the table plate is vertically pivotable. At the same time, the table plate, as a workpiece rest and carrier of additional tools, is also a lever via which deflection is brought about manually or automatically.

Title: Method for application of a mudpack
Inventor: MICHELS KURT DR MED
IPC: A61H33/04
Filed: 1982-09-21
Abstract: The invention relates to a method for application of a mudpack which consists of a wide-meshed woven sleeve and, contained therein, finely ground mud whose particle size is smaller than the mesh width of the woven sleeve, in which method the mudpack is soaked with hot water, heated in a water bath and applied to the part of the body to be treated. In a known method, the mudpack was placed in hot water and in this way soaked and heated. The mudpack was then squeezed out. Due to the washing out of mud during immersion in hot water or subsequent squeezing out, there was a considerable loss in terms of mud. The aim of the invention is to prevent this loss. According to the invention, this is achieved in a method of the above type by using, for soaking purposes, a quantity of water which can be absorbed completely by the mudpack, by using the quantity of water which can be absorbed completely by the mudpack, by placing the mudpack in a waterproof bag before or after soaking, by closing the bag in a leakproof manner and immersing it into the heated waterbath, and by removing the mudpack from the bag after heating.

IPC: B65H7/06
Filed: 1982-09-24
Abstract: The invention relates to a sheet blockage detector for detecting specific blockage states at a station (10) via which envelopes (12) are being transported away. The blockage detector uses a forward/backwards counter (30) which is coupled to a microprocessor (60) and can be incremented in response to an envelope (12) entering the station (10) and decremented in response to an envelope (12) leaving the station (10). A program routine which is provided in the microprocessor (60) forms an initial preset value for the counter (30) and generates an alarm signal when the counting value in the counter (30) is lost from a specific range. The routine determines if the counter (30) remains at a specific counting value within the range for longer than a predetermined time period and if a blockage of an envelope occurs underneath a sheet detector (18, 24) for a specific period. <IMAGE>

Title: Monitoring arrangement for a return electrode
Inventor: NEWTON DAVID W
IPC: A61B18/12
Filed: 1982-10-26
Abstract: The monitoring arrangement for a return electrode which can be attached to a patient, with two conductors disposed at a distance from one another for connecting the electrode to a generator which emits an electrosurgical current flowing via the electrode, contains a circuit arrangement which applies a monitoring current via the conductors to the electrode. A signal, which is dependent on the impedance between the two conductors, is extracted by the monitoring current. A circuit device is provided which eliminates virtually every effect which the electrosurgical current could exert on the extraction of the signal when the generator is in operation and the patient is simultaneously in contact with the electrode. A circuit arrangement is furthermore provided which specifies a desired impedance range with at least an upper limit. A device, which ascertains whether the impedance lies within the desired range, responds to the impedance-dependent signal. The upper limit of the impedance range is re-adjusted so that the system is adapted to the respective impedance of the patient, to be specific depending on the respective measured impedance which lies within the desired range.

Filed: 1983-05-20
Abstract: An apparatus for measuring the speed of a projectile fired from a handgun or small arm has a measuring path, over which the projectile passes, with light gates disposed spaced apart from one another. Each light gate has a light responsive element, which is shielded from the projectile path by a screen containing a light admitting aperture. An electronic signal evaluation circuit processes the signals emitted by the two light responsive elements in accordance with the darkening of the apertures caused by the projectile in flight above them and supplies these signals to a display device. In order to reduce to a minimum the danger of damage to the apparatus or of harm to persons, caused either by the projectile itself or by parts broken off the apparatus by the projectile without providing a connection between the barrel of the gun and the measuring apparatus, the arrangement is selected such that the two light responsive elements are disposed behind a separating wall common to both. The separating wall includes the light admitting apertures and acts as a screen. It is aligned substantially parallel to the projectile path and extends from near the muzzle of the weapon to beyond the second light responsive element, that is, the one disposed most remotely from the muzzle, and this separating wall protects the light responsive elements from the projectile.
