Title: Toothbrush - has extra tuft(s) on carrier in brush head which can be adjusted to protrude from remaining tufts
Inventor: OETZEL JUERGEN-GUENTHER
IPC: A46B9/04
Filed: 1992-03-13
Abstract: A toothbrush has several bristle tufts in the head of the brush, giving a flat brushing surface, but at least one extra tuft is mounted in a carrier so that it (or they) can protrude above the brushing surface. This allows interstitial brushing simultaneously with the normal tooth/gum brushing. The carrier slides in a tube in the brush head and can be fixed in at least two different positions. This may be done by an eccentric shaft running down the brush handle engaging a slot on the carrier; a 180 degree turn can elevate the carrier and extra tuft(s) into the protruding position from the plane position. ADVANTAGE Allows simultaneous brushing of teeth/gums and spaces between teeth
Patent DE-4209734-A1 (DE)
Inventor: ACKERMANN KARL
IPC: F24H9/14
Filed: 1992-03-25
Abstract: 2.1 In known burners with so-called hot flame tubes or corresponding ceramic combustion chambers, operating temperatures of up to 1080 DEG C are reached, the burning out of the particles and also the CO being reduced but not the NOx values. A NOx reduction is only possible with considerable construction outlay. 2.2 It is proposed, to provide a water-cooled flame tube (2) of a burner (1), its water cooling (4) being connected to the water-cooled burner housing. In the connection of a burner (1) to a heat exchanger or heating boiler (3), its water system can be utilised for the water cooling (4) of the flame tube (2). <IMAGE>

Title: Centrifuge, removing fluid efficiently from substances with small solid content, minimising stress etc. - has three rotors with 1st rotor, turning at same speed as closing unit and 2nd rotor turning at same speed as 3rd rotor having apertures leading to cells on 2nd rotor
Inventor: NAGY ADALBERT DR ING
IPC: B04B1/08
Filed: 1992-03-31
Abstract: The centrifuge has a centrally symmetric rotor (100) consisting of two coaxial sections (10,20) turning in the same direction at different speeds. The first rotor (10) consists of a cylindrical case with an outlet (12) surrounded by a closing unit (40) incorporating a drainage window (42) and rotating at the same speed. Between the first rotor section (10) and the closing unit (40) formed as a cylindrical case by the second rotor (20), is a wheel incorporating cells (22) which ejects fluid of specific weight from the centrifuge chamber (50) outlets (12) through the drainage window (42). The novelty is that the rotor (10) turns at the same speed as the closing unit (40) and is arranged between the rotor chamber and the drainage window (42) and thus prevents the immediate egress of the centrifuged product from the chamber; further that a third rotor (30) turns at the same speed as the second (20) and that the third rotor (30) has apertures leading to the cells (22) on the second rotor (20). USE/ADVANTAGE - The assembly separates substances of different specific weights. The assembly removes fluid efficiently from substances with minimum solid content and minimises physical stress and damage to the product in continual operation.

Patent DE-4220624-A1 (DE)
Inventor: BAREIS HELMUT
IPC: B62D5/083
Filed: 1992-06-24
Abstract: The invention relates to a rotary slide valve (5, 6) with a spring loaded (31) centring system (25). The centring system is to be fitted inside the valve housing (1) without the need for additional structural space in the radial direction. In addition, the return pressure is to be reduced. According to the invention, the spring (31) presses on a reaction piston (32), a centring component (24) of which acts on rolling  bodies (30) in the centring system (25). Between a cover (35) and the reacting piston (32) there is a reaction chamber (37) to which a variable pressure can be applied. At high travelling speeds, a pressure assisting the spring (31) in the reaction chamber (37) acts on a front face (41) of the reaction piston (32). Because the force of reaction pressure supplements that of the spring (31), a smaller spring can be used and space is saved.

Title: Micro-filament slashing - has superficial coating of size to assist weaving and which is removed easily at finishing
Inventor: VOSWINCKEL GERHARD
IPC: D06B3/18
Filed: 1992-10-10
Abstract: In a process to size fine capillary yarn similar to microfilament the yarn is sized, mangled and then dried. Prior to sizing the yarn is cleaned in weaker fluid, followed by a first stage extraction of fluid by a mangle, and then fully sized, followed by a single extraction similar to the first by another mangle. The appts. has driven rollers (2) to take in the yarn assembly (1) with an initial weight assessment (41). It then passes to the first immersion vat (4) under the roller (3). This vat is fed with water (28, 29, 30) and residual liq. from the end vat (24) pumped (26) through the feed pipe (25) back into the tank (27). ADVANTAGE - The yarn is only sized intensively on the other fibres so that the yarn will weave without fibres, and the size can be removed easily afterwards. There is economical use of size.

Title: Illumination device for vehicle door-lock - has small lock lamp powered from car's battery, with earth contact via door handle and time relay
Inventor: DENGLER ULRICH
IPC: B60Q9/00
Filed: 1992-10-22
Abstract: To illuminate the door lock of a car at night and thereby to enable the driver to more readily insert his key to open the door, a small lock lamp (A) has an earth contact (B) with the outer door handle. The live contact is via a fuse to the car wiring loom. Thus the driver can lift the handle to light up the lock before inserting the key. There may be a time relay in the earth connection so that the handle need be lifted just momentarily, rather than held "up". The light is a ring around the lock cylinder, or it might be mounted on the door lip. ADVANTAGE- An excellent driver-friendly device, preventing key scratches around door lock, for instance.

Patent DE-4314479-A1 (DE)
Title: Dry shaver
Inventor: BECKER KLAUS DIPL ING
IPC: B26B19/16
Filed: 1993-05-03
Abstract: In the case of the dry shaver, a shearing foil, as top cutter, is clamped over a rotating shearing roller, as bottom cutter. The clamping, shearing and frictional forces arising are directed such that they assist the mechanical stabilisation of the shearing foil. The shearing performance is thus improved, and vibration, wear and noise development are minimised by a rotational drive which is free of play during operation. Provision may also be made for a plurality of, preferably two, parallel shearing rollers, rotating in opposite directions, in a double shear head. If the shear head is mounted rotatably with respect to the housing and if the axis of rotation of the shear head coincides with at least one axis of rotation of the rotating drive system, non-symmetrical shear-head-side loading results in the shear head being rotated or inclined automatically with respect to the housing.
Patent DE-4314743-A1 (DE)
Title: Position body with inner chamber filled with contrasting medium - images and displays diagnostic sectional view which alters at least one characteristic of surface section through inner chamber depending on place or alignment of view

Patent DE-4316945-A1 (DE)
Title: Inverter-type voltage supply - uses forward voltage stabilising current circuit for lowering offset voltage by discharging forward voltage capacitor through FET
Inventor: TAMURA HIDEKI
IPC: H02M3/338
Filed: 1993-05-21
Abstract: The voltage supply includes a forward voltage stabilising current circuit which lowers the offset-voltage through discharge of the forward voltage capacitor (12) over the switched on FET (31). The FET is switched on only during a constant ON-time period, independent of the DC voltage slope inside a limited region. A forward voltage compensation device generates a negative voltage which is superimposed on the offset voltage. The offset voltage is reduced to a negative value so that the forward voltage is lowered when the DC voltage rises above the limited region. ADVANTAGE - Can use FETs with relatively low breakdown voltage.
