Patent DE-3234329-A1 (DE)
Title: Control and filter circuit
Inventor: DANNEELS JOHAN MAURITS RAPHAEL
IPC: H04M19/00
Filed: 1982-09-16
Abstract: A control and filter circuit, particularly for power-feeding telecommunication lines. The circuit contains a power-feeding circuit, an integrator, a buffer stage and a low-pass filter. The circuit is used for smoothing the voltage variation in the case of a feed-voltage change. By duplicating the filter circuit, the potentials at both ends of an output impedance, for example at both wires of a telecommunication line, can be changed essentially at the same time. The circuit can be integrated. <IMAGE>

Title: Timer for medical instruments, particularly for dental instruments
Inventor: KLEEMANN PETER DR
IPC: G07C3/04
Filed: 1982-11-30
Abstract: The invention relates to a timer for medical instruments which, in particular, can be mounted on a dental instrument which can be removed from the mouth and has counters for detecting the total time the instrument has been carried in the mouth, a miniature battery and an electrical circuit with pulse memories. This timer is intended to manage with the least possible number of counters and memories whilst having high performance and reliability. For this purpose, the electrical circuit exhibits a miniature hybrid chip which only exhibits a first counter for the daily carrying time of the instrument and a second counter for the number of daily applications of the instrument in the mouth and a measurement value pickup by which the counters, which are in each case connected to a pulse memory, can be placed into operation via a window discriminator and a control unit connected thereto.

Title: Vibration damper arranged between the transmission block and the shift linkage of a motor vehicle
Inventor: RENK ROLF DIPL ING
IPC: F16H59/02
Filed: 1983-09-09
Abstract: The aim in a hydraulic vibration damper arranged between the transmission block and the shift linkage of a motor vehicle is to ensure in conjunction with virtually no increase in the shifting forces that jumping out of the engaged gear is prevented. For this purpose a valve comprising at least one valve seat and at least one closing element preloaded into an open position away from the valve seat is arranged in the duct of the piston provided with a larger cross section, which valve presents in the open state only a slight, preferably negligible resistance to the hydraulic fluid flowing through in the event of transmission vibrations and around the closing element of which hydraulic fluid flows against the preloading force in such a way that above a predetermined rate of flow, directed counter to the preloading force and determined by the excessive transmission vibrations, of the hydraulic fluid flowing through the valve the dynamic force acting on the closing element due to the correspondingly increasing dynamic pressure becomes supercritical and overcomes the preloading force.
Patent DE-3339817-A1 (DE)
Title: Injection syringe
IPC: A61M5/315
Filed: 1983-11-03
Abstract: The cylindrical syringe body (1) of an injection syringe has at its rear end a circumferential locking groove (7) formed by two thickenings on the jacket side into which a finger support (6) having a holding web (9) on the inside engages. The thickenings which angularly delimit the locking groove (7) in its groove bottom lying against the jacket of the syringe body are formed by a socket bead (10) of semi-circular cross-section facing the front end of the syringe body and an abutment bead (11) of ratchet type cross-section lying against the rear end. The outer diameter of the socket bead (10) is made to be smaller than the largest outer diameter of the abutment bead (11). The circumferential abutment bead (11) is arranged so that its ratchet-type tip which is preferably rounded points outwards and toward the front end of the syringe body; this tip is adjoined by a support surface for the holding web (9) of the finger support (6) at right angles to the longitudinal direction of the syringe body. These beads (10, 11) permit simple fabrication of the entire syringe body (1) and sliding-on of the finger support (6) from the front end of the syringe body, as well as reliable locking connection between syringe body (1) and finger support (6) coupled with easy handling in the locked position. <IMAGE>

Title: Method and device for the power supply of digital clocks
Inventor: LUEHR HANS-JOACHIM
IPC: G04C10/00
Filed: 1983-12-22
Abstract: The two battery terminals of a digital clock are connected to an externally accessible connecting socket on the housing of the digital clock (1). The battery (10) of an external power supply apparatus (8) can be connected to the connecting socket in order to maintain the power supply to the digital clock (1) while its internal battery (17) is being replaced. In consequence, the data which are stored in the digital clock, especially the time indication, are maintained while the battery is being replaced, so that it is not necessary to reset the digital clock after battery replacement. A volt meter (19) is also arranged in the apparatus (8), which volt meter is used, after an interruption in the connection to the external battery (10), to measure the battery voltage of the internal battery (17) of the digital clock (1), via the connecting socket. <IMAGE>

Title: Apparatus for the drying of thermolabile products which are liable to cake
Inventor: MOERL LOTHAR PROF DR SC TECHN
IPC: B01J8/18
Filed: 1984-01-07
Abstract: The invention has the aim of developing an apparatus with which caking of, and thermal damage to, the products during their drying can be prevented and the product yield can be increased. The object is derived from this of keeping all apparatus parts which can come into contact with the material to be dried below the temperature at which a danger of caking and of thermal damage are present. This is solved according to the invention in that in a known fluidised bed apparatus all the walls in and around the drying space are surrounded by spaces through which, respectively separated, a cooling medium can be conducted, and throughflow regulating members are arranged in the inlet and outlet pipes.

Patent DE-3404934-A1 (DE)
Title: Cylindrical silo
IPC: B65G65/06
Filed: 1984-02-11
Abstract: The cylindrical silo has a discharging device which is mounted on a central column and has a conveying device which circulates round a vertical silo axis, is inclined in relation to the silo floor and the discharging tools of which describe a free-cutting curve in the material contained by the silo, which curve is inclined and is situated in a vertical plane. The topmost and bottommost points of the free-cutting curve in the material contained by the silo, seen in the radial direction of the cylindrical silo and perpendicular to the vertical plane containing the free-cutting curve, are approximately the same distance from the vertical silo axis. The vertical plane in which the free-cutting curve is situated is tangential to a circle around the vertical silo axis. The conveying device can travel in a translational manner in the radial direction of the cylindrical silo. By means of this discharging device, the material contained by the silo in the region of the central column can be almost completely discharged. Only a small dead space which is inaccessible to the discharging device remains in the region of the casing of the silo. The cylindrical silo displays a high degree of space utilisation and the free surface of the stored mass is very small.

Title: Bottle feeding and distributing table
Inventor: MUELLER FRIEDHELM
IPC: B65G47/68
Filed: 1984-05-19
Abstract: Bottle distributing tables are generally used for temporary accumulation of the superfluous bottles advanced from a bottle treatment machine arranged upstream when the machine downstream is running with a decreased output and/or has a malfunction, and then for feeding the said bottles to the machine downstream again once normal throughput has been restored. With this design, in contrast, bottles are to be passed into individual conveying channels at a high speed without backpressure, the aim being to provide sufficient follow-on capacity with a low backpressure. To this end, the invention provides, in a bottle feeding and distributing table, for the discharging path to be essentially opposite the inflow path and to be formed from individual channels which are gradated according to length at an angle to the main direction of movement, for an onward conveyor with at least one track to extend towards the return region next to the last filling channel in the conveying direction, and for a deflection device which is known per se to be provided at the end of the return region to deflect the receptacles waiting there towards the main stream.
