Title: Pressure-sensitive, elastic tooth-brush - which has very thin handle, on both sides of which are square smooth knobs near thumb support, which press on fingers when excess pressure is applied
Inventor: VUKOSAVLJEVIC JOVICA
IPC: A46B5/00
Filed: 1992-07-18

Title: Textile machinery - has arrangement of filtrate in air circulation extraction chamber to prevent choking with dust, lint and fly
Inventor: GRANDEK MANFRED
IPC: D01H11/00
Filed: 1992-09-04
Abstract: On a textile machine which is working with yarn, dust, tint and fly is created, which is drawn away by suction into a container. A filter arrangement is in the container. By means of a double filter screen arranged in a specified manner, the turbulence created prevents the debris settling, and air passes continuously through the extraction chamber without choking the filters. Pref. typically the suction around the working parts of the machine is drawn into the filter chamber (20) through the ducting (19). The suction is created by a motor driven rotary extractor fan at the front of the chamber housing (37). Behind it is the first filter screen (30), which is not taken completely across the chamber. It is angled back by the second screen (35), which crosses to the back wall. In this wall there is a trap which may be unfastened and removed to take out the debris which has accumulated. ADVANTAGE - The air circulation continues until the container is full, efficiency improves, and debris does not impair the working of the machine, which may cause faults in the yarn.

Title: Pressure regulating valve with proportional solenoid - has spool with displacement provided by proportional solenoid operating a small valve to vary pressure applied to end of valve spool
Inventor: BREHM WERNER DIPL ING
IPC: F16H61/02
Filed: 1992-09-24
Abstract: A pressure regulating valve has a control slide (70) that is displaced to vary the amount of flow passing from a supply port (P) to an output (A); flow is returned to tank (T). The control of the spool position is provided by a proportional solenoid actuator (12,26,29). This causes displacement of a valve element (53) that varies the pressure applied to the end of the spool. The fluid in the end chamber (72) is provided by a centre connection through the spool body to the supply port. Movement of the solenoid either opens or closes an orifice to vary the pressure applied to the end. A diaphragm (38) separates the solenoid from the spool. USE/ADVANTAGE - Compact, high accuracy valve with small proportional solenoid.

Title: TV ghost picture eliminating device - uses ternary sequential signals to distinguish between before ghost, after ghost and approaching ghost pictures
Inventor: PARK HYUNG MO
IPC: H04N5/21
Filed: 1993-04-16
Abstract: The device has a ternary sequence generator (1) in the TV transmitter to generate a training signal. This is inserted in a vertical period of a video signal for high frequency modulation. A demodulator (12) in the TV receiver receives a transmitted signal and demodulates it to the original video signal. A line selector (16) selects a line into which a training signal is inserted which is demodulated in the demodulator (12). A ternary sequential reference signal corresponding to the training signal is generated in the generator (1) and is stored in a memory (18). A cross-correlator (17) correlates the reference signal and training signal and from this produces a ghost channel. A ghost filter (19) eliminates ghost pictures from the video signal according to a filter coefficient value of the ghost channel. ADVANTAGE - Simple efficient system which provides good quality pictures with neither distortion nor delays.
Patent DE-4312567-A1 (DE)
Inventor: JOCHUM PETER
IPC: B25D9/11
Filed: 1993-04-17
Abstract: The powder-actuated driving tool has a piston return mechanism operating through the use of compressed propellant gases. For this purpose, propellant gases pass from an opening (6) via a passage (5) through an opening (7) into the guide bore (2a) of a piston guide (2). The piston (1) is driven by the compressed propellant gases from its front end position into its rear initial position until it comes to bear on the base (4c) of a cartridge carrier (4). While the piston (1) comes to a stop, the cartridge carrier (4) is displaced to a limited extent against the driving direction. For this purpose, the cartridge carrier (4) is connected to a housing part (3) via a buttress thread (3a, 4a) exhibiting backlash. <IMAGE>

IPC: F16C11/04
Filed: 1993-06-29
Abstract: A sliding coupling system has an inner member with a sliding part, and an outer cylindrical member which is open at at least one end, holds the inner sliding part, and has an annular groove in at least one end; a synthetic resin sliding member meets the inner face of the outer member and has an inner face sliding over the outer face of the other sliding member; a safety ring engages the annular groove and meets one of the ends of the second (resin) sliding member so as to prevent axial movement of the latter; the latter has also a component in the annular groove to fill the gap between the inner face of the annular groove and the safety ring. The example, shown is a vertical view; it has spherical type bush, in which the inner member (10) is a metal tube made integrally with the sliding sphere (12) which projects radially outwards and has a convex outer face (14). An outer metal part (16) is also cylindrical and has a relatively thin wall. The concentric assembly leaves a space between the outer (16) and inner (10) parts; the two ends are both open. The sliding member (26) has a liner (30) of e.g. Teflon (R.T.N.), the member (26) is e.g. low friction acetal polymer. It has a safety split ring (22) in an annular groove (20). ADVANTAGE - The system is simple in its construction. Its component parts do not chatter or become displaced in service; they do not change their action on the slide faces, so that the system has good stability and low friction movement.

Title: Process for the direct processing of waste products of thermoplastics to form semifinished or finished products
Inventor: KAEUFER HELMUT PROF DR
IPC: B29B17/00
Filed: 1993-08-09
Abstract: The process serves for the more cost-effective and environmentally acceptable reprocessing of waste thermoplastics. By dispensing to a great extent with comminution, in particular grinding of the waste products, and direct processing of the reprocessed polymer melt to form products with defined requirements, energy consumption, reprocessing costs and environmental pollution can be reduced. The process is of a modular design and can be varied according to the field of application. Taking into consideration the requirements for the final product, the other process modules which are needed for the required quality of the secondary plastic are selected. Cleaning of this shredded material is not absolutely necessary, since impurities can be incorporated into the material.
