Title: Fish filleting appts. with simpler operation and better output - has two=part spreader on inner side of ring cutter and cut away section on outer side of ring cutter
Inventor: KOVAL LEONID PAVLOVIC
IPC: A22C25/16
Filed: 1990-05-30
Abstract: Appts. for filleting fish consists of transporting and cutting knife systems mounted on a frame. A two-part spreader is located symmetrically on both sides of the knives such that it covers the cutting edges on the inner side of the ring cutter. - A pair of extended elements are attached to the spreader to centralise the fish backbone.

Patent DE-4023157-A1 (DE)
Inventor: STIEGER OTHMAR
IPC: B21D51/26
Filed: 1990-07-20
Abstract: A sheet blank (10) can be moved through between a first and a second bending roll (24, 25). Arranged behind the bending rolls (24, 25) in the direction (12) of motion of the blank is a deflector (28), at which the sheet blank (10) can be deflected away from the first bending roll (24) out of its original direction (12) of motion and around the second bending roll (25). To intercept the forward edge of the sheet blank (10) in the original direction (12) of motion, an intersecting strip (29) is arranged at that side of the second bending roll (25) which faces away from the first bending roll (24), at least approximately in the common plane of the axes of the two bending rolls (24, 25). The intersecting strip (29) is part of a guide rail (30), along which the rounded sheet blank (10) is guided with the longitudinal edges close together during an axial onward movement. The guide rail (30) extends at least approximately over the entire length of the two bending rolls (24, 25) and is arranged in such a way that the sheet blank (10) surrounds it during the bending of the latter.

Title: Hydro-cyclone for separating solid matter from water -  has deflector vanes formed on wall of inner chamber
Inventor: AUST WERNER
IPC: B04C5/02
Filed: 1990-08-24
Abstract: The hydro-cyclone for separating solid matter from the liq. in which it is suspended, has a cylindrical outer chamber (1) which encloses a smaller dia. inner chamber (4).

Patent DE-4117787-A1 (DE)
Title: Radio broadcast transmission using variable dynamics - transmitting time reference signal in programme signal and radio data system signal, for exact correlation of time-varying control signal
Inventor: EINSEL ROBERT DIPL ING
IPC: H04L7/00
Filed: 1991-05-31
Abstract: A time-varying control signal contg. information about variations in the original radio programme signal is transmitted so that a receiver can restore the broadcast studio adjustments w.r.t. variable dynamics. The control signal is transmitted in a stream of RDS data as a time-correlated auxiliary carrier in the stereo multiplex signal. In order to perform exact time-correlated assignment of the time-varying control signal to the stereophonic radio programme signal, a time reference signal is applied to both the radio programme signal and to the data stream of the radio data signal. The terrestrial transmitter pref. uses a synchronising appts. with a comparator circuit to provide exact time-correlated broadcast of the programme signal with the control signal. The radio receiver may comprise several receivers, the outputs being combined after synchronisation. ADVANTAGE - Improves quality of received signal, e.g. same signal received from different transmitters.

Title: Brake system for hinging lid - has cured tongue integral with arrester arm and of wedge-section
Inventor: POWELEIT UDO
IPC: E05C17/20
Filed: 1991-07-08
Abstract: The brake slows down the opening movement of a hinging compartment lid, partic. the glove box in a car dashboard.  A curved arrester arm on the inside of the cover passes through an aperture in the edge of the compartment opening which is shut by the lid.  Friction between a braking component in a recess in the arm and the edge of the aperture opposes the opening movement.  A stop on the arm limits the amt. of this movement. The braking component consists of a tongue (10) with curved lengthwise edges (12,13), joined to the arm (6), with which it is integral, at the lid end of the recess (11), and also at the inner lengthwise edge (12).  Seen in cross-section, it widens from the inside to the outside edge (13), so as to form a wedge. USE ADVANTAGE - Simple, rapid and low-cost production.
Patent DE-4123226-A1 (DE)
Inventor: BOEHME HERBERT
IPC: F16N29/02
Filed: 1991-07-11
Abstract: A circuit arrangement for controlling the lubrication of trailers of utility vehicles is proposed, in which a capacitor is used which is charged as a function of the actuation of the brake of the utility vehicle for the purpose of supplying the circuit arrangement with voltage. A microcomputer counts the number of brake actuations, stores them and compares them with a predetermined number, a valve for triggering the lubrication being actuated in the case of identity. A monitoring circuit monitors the capacitor voltage. If the latter drops below a predetermined value, the number of brake actuations buffered in the microcomputer is transferred into a non-volatile memory. After renewed charging of the capacitor after a brake actuation, the contents of the non-volatile memory are loaded into the microcomputer again. <IMAGE>

Inventor: ZAWADKE THOMAS
IPC: B60K15/077
Filed: 1991-07-19
Abstract: 2.1 A known liquid vessel has separate tanks of modular construction with plane peripheral walls, the separate tanks being connected to one another by connecting pipes. The overall construction is comparatively bulky and makes assembly difficult due to the leak-prone connecting pipes. 2.2 According to the invention a tank construction (1) is proposed with tank modules of essentially identical design, each tank module having at least one convex bulge (5 and 6) and at least one concave indentation (7 and 8). The convex bulge of one tank module can be brought into a positively interlocking, tightly fitting engagement with the concave indentation of an adjacent tank module resulting in a compact overall construction of a rigid vessel, in which the connecting pipes can be omitted. A tank construction (1) of this type can be designed and if necessary expanded as required for a mobile tank on a vehicle or as a fixed tank system. <IMAGE>

Title: Purifying waste water in dentists surgery - by passing water through holding tank in which impurities are sedimented and drained at intervals into removable container for disposal
Inventor: ROPERS TILL DR
IPC: C02F9/00
Filed: 1991-09-25
Abstract: In a procedure for sepg. impurities from waste water in dentist's surgeries, the water is held in a holding vessel until the impurities are sepd. by sedimentation, and the impurities which are deposited in a sedimentation zone at the floor of the vessel are transferred at regular intervals to a sediment collecting container. Water overflowing from this container is pumped back into the holding vessel and the container is from time to time cleaned externally, sealed and disposed of. Specifically, waste water enters the holding vessel via an upper inlet and leaves it via an outlet just above the sedimentation zone. A vacuum pump may be used to reduce the pressure in the holding vessel and may be in the form of a water-ring pump or a vacuum cleaner pump. The vacuum cleaner pump may be used as an emergency back-up pump. The pref. configuration has PVC tubes, whose lower ends are open to the sedimentation zone, the inlet being in the upper part of the first tube, the upper ends of neighbouring tubes being connected by pipes and the upper end of the last tube being connected to the vacuum pump. The tops of the tubes are at the same level and their lengths reduce from the first to the last. The floor of the sedimentation zone is inclined towards one end. A valve connects this zone to the sediment container. A filter, U-tube and sample-point are provided in the water outlet. USE/ADVANTAGE - Used in removing impurities, and especially amalgam, from waste water in dentist's surgeries. The proposed system is economical and simple in operation. Maintenance requirements are much less, and the efficiency of separation is improved in relation to existing systems.
