Patent DE-3716987-C1 (DE)
Inventor: IMHOF AUGUSTIN
IPC: G07C1/24
Filed: 1987-05-21
Granted: 1988-04-28
Abstract: When a competitor or a group of competitors passes the finishing line, a video camera (6), two time generators (8), a video recorder (9) and a display in the form of a monitor (11) and/or of a video picture printer (12), and a light barrier are able to produce, in a very inexpensive way, finishing-line pictures with at least two times faded in, namely the true finishing time of a first competitor triggered by the light barrier and the precise time which has elapsed from the start at the time said picture was taken. From the time difference, distance sections each corresponding to one hundredth of a second can be determined from which the finishing times of the runners arriving immediately after the winner can be exactly established. In practice one finishing-line picture is sufficient to be able to measure precisely to one hundredth of a second the finishing times of runners arriving almost simultaneously with the winner. Competitors arriving after a fairly large interval can in turn obtain their exact finishing time by means of the light barrier in a further still picture.

Title: Locking device for a ball-headed coupling
IPC: B60D1/06
Filed: 1988-07-15
Granted: 1990-02-15
Abstract: A description is given for a locking device of a ball-headed coupling for the releasable connection of a towing recovery tank to a tank to be towed away, a spherical cup being held on a drawbar of one tank and the locking device including a ball head being held on the other tank. In the connected condition of the coupling, a latching element engages over the spherical cup and holds it firmly on the ball head. The latching element is articulated about a transverse axis above the ball head to allow it to pivot into an uncoupled position and into a coupled position and is pivotably connected to a release lever pointing towards the ball head. This lever interacts with a locking lever pivotable about a longitudinal axis of rotation. <IMAGE>

Title: Rotary spray coater - has atomiser ring with solvent channels, and includes annular air inlets
IPC: B05B15/55
Filed: 1989-04-18
Granted: 1990-10-11
Abstract: Rotary spray comprises rotor, atomiser ring with  shaft connection boss and a coaxial annulus into which  issue paint and solvent lines for onward feeding to the front of the ring, with a solvent channel leading from the annulus to an axial recess in the front of the boss. This channel (40) between annulus (18) and boss recess (15,42,43) should run through the boss (15) at an angle to the rotation axis (16) so the channel inlet (48) is at the front end of the annulus in the transition (50) between boss rim and rear surfaces (20,22).  The inlet radiates far enough on the rear surface (22) to register with the outlet of the solvent line (31 (51) and so direct solvent from the line to the boss recess (42). A first annular air inlet (75) at the annulus rear sets up an air flow ring towards the front of the annulus (23) along the boss (15) so that the air flow ring is impinged by the solvent from the line outlet (51) towards the boss surface (20), the air ring thus enveloping the solvent and forcing it to the channel inlet (40). USE/ADVANTAGE - Industrial coating, e.g. paint sprays.  Directed solvent flushes paint deposits clear between paint changes.

Title: Skip or container handling system - incorporates crane with grab mounted on lorry
IPC: B66C1/66
Filed: 1990-03-17
Granted: 1991-10-17
Abstract: Container disposal system uses a swivel grab fitted to a mobile crane so the two grab jaws can converge their claws hydraulically onto the endfaces of the container for lifting, tipping and lowering. A truck with mounted crane should be used to lift, tip and lower the containers (3) brought empty on the truck to the disposal point, for offloading, filling with disposal spoil etc. by the crane and then replaced on the truck for removal. At the bottom ends of the two grab jaws (15, 16) are claw supports (49, 50) which swivel round an horizontal axis under power and are each fitted with the claws (15 and 16). Several identical containers all have claw entries (67, 69) facing one another and opening outwards, each container formed from a downwards tapering body (3) terminating at the top in a collar (71) with vertical walls parallel to one another (71). USE/ADVANTAGE - Container handling, e.g. building skips. Truck has own crane for skip handling, loading and replacing.

Title: Fastener for releasable coupling of exchangeable machine parts - has nut thread for coupling stub threaded section on axially fixed, rotary coupling ring
IPC: B23Q3/12
Filed: 1992-02-01
Granted: 1993-02-18
Abstract: The releasable connector between machine parts consists of a rotary journal with thread and nut and end fitted bolt to engage a socket in the part connected to the machine. The bolt head consists of a shoulder which is wider one way and narrower in a second direction at right angles to this so as to lock into an undercut part in the bolt socket in the appropriate journal position. An adjuster bolt on the machine is cross-toothed to form a rack engaged by a gear on the journal. The nut thread (11) for the threaded part of the journal (10, 4) should be on an axially locked clamping ring (19) which can rotate relative to the journal and is toothed (20) outside to form a gear thus meshing with the rack formed by the cross toothing on the clamping bolt (22) fitted to the machine. USE/ADVANTAGE - Machine tools, e.g. coupling milling/boring heads to machine spindles etc. Clamping ring and gear teeth increase connection surface to machine racked clamping bolt on machine with bolt action for clamping and release.

Title: Charge pump
Inventor: GLEIS DIETER DR ING
IPC: G11C5/14
Filed: 1993-07-23
Granted: 1994-09-22
Abstract: A charge pump has two push-pull pump halves (1, 2). Each half includes a sliding capacitance (11, 19) and a PMOS transistor (10, 17), connected between the sliding capacitance and a storage capacitance (5). The sliding capacitance is charged to the full supply voltage (VDD) via an NMOS transistor (12, 18). In this arrangement, the gate control voltage is above the supply voltage (VDD) and the PMOS transistor is reliably blocked by the output level (A) fed back to its gate terminal. Since the PMOS transistor is made conductive with the full output voltage (A, VSS) during the sliding action, reliable pumping operation is possible even when there are variations in the supply voltage (VDD). <IMAGE>

Title: Method for introducing structures in smooth surfaces of hard materials
Inventor: WUENSCH JENS
IPC: B44C1/00

Granted: 1996-03-07
Abstract: The method is for the introduction of structures in smooth surfaces of hard materials by the conversion of the compsn. and the structure of the areas close to the surface. An electric motor (1) is involved which drives a pliable shaft (2). The shaft on the side away from the motor has a grip piece (3) with a rapid clamping device in which a 20mm long steel wire is so clamped that approximately 10mm remain free. A round pointed steel pin 0.5mm to 2mm thick is used, made of an alloyed, stainless steel. It is rotated at a speed of 3,000 to 20,000 rev/min and has a wt. force of 50g to 1,000g. It is positioned at an angle between 70 and 90 deg. to the workpiece surface and is moved with a speed of 0.5 to 10 cm/s over the workpiece surface, producing a line. By producing a series of adjacent lines, the required structure is obtained. The wire pin is made of a steel comprising X 12 CrNiMn 19.9.

Granted: 2008-06-23
Abstract: The invention relates to a method for securing a space against danger of gas explosion, comprising of detecting the composition of the atmosphere in the space and generating a warning signal when the detected composition becomes explosive, wherein an explosion-inhibiting agent is introduced into the space when the warning signal is generated.  The explosion-inhibiting agent, which can bind potentially explosive elements in the atmosphere in the space, can be introduced into the space in the form of an aerosol which can be formed by chemical decomposition of a solid present in or close to the space.  Additionally or instead, it is possible to envisage the atmosphere in the space being detonated when the warning signal is generated.  The invention further relates to a security device for performing this method.
