Patent DE-4212151-A1 (DE)
Inventor: GOLLWITZER RAINER
IPC: B02C18/00
Filed: 1992-04-10
Abstract: The invention relates to a method, which is simple to execute, for monitoring the operation of mechanical paper shredders. The current coasting behaviour of the blade rollers is determined and compared with the coasting behaviour of correctly operating blade rollers. Deviations in the coasting behaviour indicate impairment of the operation of the blade rollers currently in use. Depending on the degree of deviation, measures are initiated which eliminate the operational impairment. <IMAGE>

Title: Multiple redundancy safety circuits for hazardous process control - uses stored program controller with interlocked serial protection switches
Inventor: WAHL EGON
IPC: G05B19/05
Filed: 1992-04-22
Abstract: The safety protection circuit consists of a stored program control(SPS) device which outputs control signals to hydraulic actuator valve(Y1). Input signals(2-Hand...) are monitored by dual supervisory circuits(ueberwachung 1,2) which control serial interlock switches(V25.1,V25.2;V30.1,V30.2). A low voltage detector circuit cuts power to the hydraulic system when control logic power fails. USE - Safety circuit use in hazardous processes, e.g. hydraulic press,automatic assembly tools etc. where high numbers of machine cycles are concerned.

Patent DE-4316513-A1 (DE)
Inventor: HOFFMANN ERWIN
IPC: G01N21/31
Filed: 1993-05-17
Abstract: In an atomic absorption spectrometer for measuring mercury concentrations the dynamic measurement range is considerably increased by providing a radiation source (2) which produces the emission lines 253.7 nm and 184.9 nm at the same time, that said radiation simultaneously impinges through the test sample (3) on two electro-optical transducers (9, 10) of which the one transducer is substantially sensitive to the emission line 253.7 nm and the other one to the emission line 184.9 nm. Atotal measurement range covering about four orders of magnitude can he implemented thereby. The transducer detecting the 184.9 nm line has a Csl photocathode and is used over a lower range of extinction values/mercury concentrations; the other transducer has a CsTe photocathode and is used over a higher range. <IMAGE>
Patent DE-4320193-A1 (DE)
Title: Apparatus for the feed and individual separation of rotationally symmetrical workpieces
Inventor: BLOCK MARIO DIPL ING
IPC: B65G47/14
Filed: 1993-06-18
Abstract: In the individual separation and feed of rotationally symmetrical workpieces, the disadvantage of known apparatuses is that parts not having any exact length tolerance are fed for further processing and therefore produce a reject or block the sequence of the apparatus. The new apparatus is to make it possible for parts outside the length tolerance not to be fed and for the individual separation and feed to take place at a high working speed. This object is achieved in that there are on the pivot axis (3), according to the number of individual separations, receiving bores (22) with sensors which are in line with entry mouthpieces (7 to 11) or blow-out mouthpieces (12 to 16) and with the incoming-air throttles (17) and these sensors record and pass on the presence or absence of parts having the correct tolerance. <IMAGE>
Patent DE-4320459-A1 (DE)
Title: Sound pipe, provided with additional masses for harmonising the overtones
Inventor: BYSTRICKY WERNER
IPC: G10D13/10
Filed: 1993-06-21
Abstract: The sound of a sound pipe is determined by the interplay of the fundamental tone with the overtones. In this connection, the overtones have a non-harmonic relationship with the fundamental tone so that, in particular in the case of interplay with other instruments or other sound pipes, harmonically unsatisfactory overall sounds can arise. By arranging one or more additional masses, the individual part tones of the sound pipe can be influenced in different ways. The main problem is determining the positions and masses of the additional weights. In this case, the mathematical modelling of the vibrating overall system can decisively reduce the extent of empirical investigations. Using this tuning method, it is possible to produce sound pipes with completely determined sound ranges. Thus, for example, it can be achieved that the fundamental tone, together with the first two overtones, generates a major or minor triad, or that overtones have an octave relationship with the fundamental tone.

Title: Device for opening and resealing bottles with crown caps
Inventor: LISCHAK BAERBEL
IPC: B67B7/16
Filed: 1994-01-17
Abstract: In known, commercially conventional crown cap openers, the crown caps are deformed and can therefore not be used for resealing. The new device makes repeated opening without damage and resealing with a crown cap possible. In order to be able to remove the crown caps without damaging them, the opener is made of a planar base plate (1) which forms an extension of the handle (2) and of a lifting plate (3) which is situated below the latter, the internal distance between it and the base plate (1) exactly corresponding to the height of the crown cap. The lifting claw (3) is adapted to the curvature of the crown cap and is provided with an acute angle opposite the operating side. The slightly curved pressure plate (4) for the closing element forms the extension of the handle (2) on the opposite side of the opener. Furthermore, the closing element is composed of a shell (5) which is situated beneath the pressure plate (4). The shell (5) acts as a stop during the closing process and is used to fasten and stabilise the pressure guide (6). The pressure guide (6) which engages beneath the reinforcing edge of the bottle neck during the closing process is advantageously coated in plastic. This combination of opener and closing device without moving parts makes repeated opening and resealing with the same crown cap possible. <IMAGE>

Title: Horizontal conveyor for moving pallets
Inventor: HEILIG KURT
IPC: B65G17/00
Filed: 1994-02-10
Abstract: The contact face (41) of the pallet (26) facing the underneath of the chain is formed on a counter holder (34) which is part of the pallet and which is restricted by two stop faces (40',40'') which point in the transport or counter direction. The distance between the stops in the transport direction of the roller chain (22) is measured depending on the distance between the roller axles and the diameter of the upwardly conveying guide pulley wheel. In the circumferential area of the pulley wheel, when a roller adjoins the contact face in the longitudinal centre of the counter holder (34) the two adjoining rollers (44',44'') each touch one of the two stop faces of the counter holder. The conveyor has two parallel roller chains and the counter holder of each pallet engages through the inter-space between the two chains.
