Patent DE-4001868-A1 (DE)
IPC: A63F9/04
Filed: 1990-01-23
Abstract: A word forming action game comprises two sided disks 50 with a consonant on one side and a vowel on the other. The disks are stacked in a cylindrical magazine 34 so that the letters of all but the upwardly facing side of the topmost disk are obscured from view. Adjacent to the bottom of the magazine is a biased arm 42 for propelling the bottommost disk of the stack out of the magazine into a central playing area 14 having a depressed centre 18 surrounded by a raised ledge 20. As the propelled disks 50 hit the vertical edge 22 between the depressed central area 18 and the raised ledge 20 surrounding it or another disk, the disks 50 tend to spin and tumble about precluding certainty of what letter will finally appear on the upwardly facing side of the disk when the disk comes to rest. Players attempt to form words using letters on the upwardly facing sides of all of the disks in the central playing area and the first player to form such a word removes the disks used in forming the word. <IMAGE>

Title: Bonding thermoplastic bristles and brush - by heating ends of bristles on holder, heating bores in brush body, inserting bristle ends into fused bores and allowing assembly to cool
Inventor: BICKEL WOLFGANG
IPC: A46D3/04
Filed: 1990-05-10
Abstract: Thermoplastic bristles are bonded to a thermoplastic brush body by fusing the ends of the bristles without thickening them and fusing also points on the side of the body, inserting the bristles into the body, and holding them there while the fused areas cool down. The bristles used are extruded and stretched polymer; their ends are heated until they fuse together without thickening; these softened ends of the bristles are inserted into undercuts on the body made by fusing also and are bonded or whilst forming thickened parts. The bristles (2) are mounted in their holder (3) with the ends of the bristles in their bores (3.1) flush with the underside of the holder (= 3.2). A heater (4) is now brought between the holder (3) and the brush body (1) and is moved so that the top face (4.2) of the heater is close to the underside (3.2). ADVANTAGE - The method enables bristles and bodies of different thermoplastic polymers to be bonded together perfectly. It stops the brush body from warping on account of the contraction in volume arising when the bristles cool down; this avoids the formation of poor finishes.

Title: IC engine fuel-injection pump - has plunger top edge with higher sections advancing timing for starting and idling
Inventor: SCHENK BERNHARD
IPC: F02M59/26
Filed: 1990-07-28
Abstract: The fuel-injection pump is for a compression-ignition engine, having a plunger turned to vary the quantity injected per stroke.

A top edge has sections at different heights, timing the start of injection. The top edge (5) has a first section (III) advancing injection when starting, a second (IV) offset from the scroll edge (6) retarding injection at full or nearly full load, and a third (V) roughly at the height of the first, advancing injection for low load and idling. The mount of the controlling suction and spill port (8) is of a cross-section formed by two overlapping circles (13,14) whose centres are on a line in the stroke direction.  During the injection stroke, the control face (7) passes first over the larger circle and then over the smaller one. ADVANTAGE - Rapid and accurate adjustment of injection timing largely irrespective of speed.

Title: Rotating actuating cylinder for machine tool spindle chuck - has piston rod axial motion transferred to switching bar which can be changed to re-program chuck
Inventor: ROEHM GUENTER HORST
IPC: B23B31/30
Filed: 1990-10-06
Abstract: The actuating cylinder (1) is fastened to the end of the machine spindle and rotates with it. Moving axially within the cylinder is the piston and rod (2), one end of which (2') is attached to the drawbar of the chuck. The other end passes through the rear wall of the cylinder and carries on bearings (8,9) a fluid (air or oil) distributor (4) which enables fluid to be supplied through passages (12,13,18,19) to either side of the piston. The distributor is fixed rotationally but moves axially as one with the rotating piston rod (2). A bar (26) carrying switch trips (21) is supported in the bore (27) of a radial extension (33) of the distributor and locks into a bracket (17) which rides on the outer race of bearing (24) at the rear of the cylinder.  When the piston rod moves axially, the switching bar (25) is held stationary and the micro-swtiches (20) are switched to control the chucking cycle as they move past the trips (21).  A different chucking cycle is obtained by unlocking the switching bar and replacing it with a new one. USE/ADVANTAGE - Quick and accurate reprogramming of chucking cycle.
Patent DE-4041106-A1 (DE)
Title: Rotating component monitor - in which yarn defect signals are used to identify component fault or wear automatically through an electronic circuit
Inventor: GOEBBELS HEINZ-DIETER
IPC: D01H13/26
Filed: 1990-12-21
Abstract: To determine if the rotating components which prepare and feed fibre or roving materials at a spinner are faulty or functioning incorrectly, yarn fault signals are processed by an electronic circuit. If the fault signals exceed a tolerance limit, the electronic circuit automatically checks subsequent yarn passages periodically to determine if the same or similar breach of the tolerance recurs. This gives the cause of the fault from the technical data and/or appts. setting data and/or the rotating components in terms of faulty setting, defect or wear. With a multiple defect signal pattern, at each anticipated yarn point, an automatic indication shows the faulty setting and/or the component with faulty operation or defect or wear and/or the spinning operation is stopped. To check on repeated and periodic fault signals, they are taken on a preset length tolerance plus and minus of each yarn point passing round the component once or more times, multiplied by the draft of the drawing unit between the component under scrutiny and the yarn measurement point, and also multiplied by at least the correction value for the staple length. ADVANTAGE - The technique gives a rapid, effective and economic process to identify faulty components, for immediate correction which prevents faults spreading.
