Title: Microfocus X=ray generator with optical spot size sensor - has mirror for reflecting visible and near IR light but not X=rays, adjusting electron beam for max. brightness
Inventor: CUEMAN MICHAEL KENT
IPC: H05G1/36
Filed: 1990-10-18
Abstract: A microfocus X-ray tube has an anode that emits X-rays and, a biproduct of its waste heat, visible and near infrared light. The biproduct light is used to adjust and maintain the focus of the electron beam and enhance the performance of the X-ray tube as a point source of X-rays. Only the light is reflected by a mirror along a path in which a view port is placed in the tube envelope. A sensor, e.g. a photodiode, or television camera, is placed in the path. A display e.g. a television display, meter, etc. can be connected to the sensor to display the emitting spot of the anode or the amplitude of the emission. - The focus of the X-ray tube is assured by observing the biproduct light and adjusting the electron beam to either minimise the size of the glowing spot or maximise its apparent brightness. A method for use with an emitter of first and second types of radiation comprises reflecting only the second type of radiation, and sensing the reflected radiation. A microfocus X-ray tube features a mirror for reflecting light but not X-rays. A view port such as quartz can be disposed in the path of the reflected light in the tube envelope.

Title: Controlling energy characteristics of power press - with energy transfer between air-hydraulic intensifier and displacement pump-motor coupled to crankshaft
Inventor: PETTER WIELAND DR ING
IPC: B30B15/00
Filed: 1990-12-29
Abstract: In a conventional power press drive energy is normally lost in the form of heat emitted by the clutch and brake during the press working cycle. In the modified press a hydraulic variable displacement unit (12) is coupled to the drive by shaft (13). The unit can function as pump or motor and is hydraulically connected to an air-hydraulic intensifier (15). By suitable control of the actuating cylinder (5) and the flow of oil between the displacement unit (12) and intensifier (15), the displacement unit draws energy from the intensifier to apply an accelerating torque to the crankshaft at the start of the press cycle and returns energy to  decelerate the crankshaft towards the end of the  cycle. USE/ADVANTAGE - Power press drive with reduced wear of clutch and brake. More efficient energy usage. Reduced noise.

Title: Sewing machine layout - has multidirectional stitching facilities with automatic cloth control
IPC: D05B21/00
Filed: 1991-01-30
Abstract: Sewing machine layout consists of a large table with a central turntable on which the sewing head is positioned vertically and a cloth advance mechanism beneath.

Title: Injection moulding combination material - by plastifying e.g. two different polymers individually in separate extruders and injecting so that their two flow fronts meet appropriately
Inventor: OPELKA GERHARD
IPC: B29C45/00
Filed: 1991-03-07
Abstract: Injection mouldings are produced from at least two different plastic materials fed from at least two extruders and injected into the one mould, whereby they are bonded together at at least one seam. In the process the materials are caused to meet by flowing in different volumes and in opposite directions whilst still making their joint externally visible. Pref. the (e.g.) two plastic materials are plasticated quite separately and therefore under conditions appropriate for their two particular properties. In the same way they are injected into the mould at separately adjusted rates, pressures and dwell pressures. The two melt streams must meet and bond well together at a predetermined place; for this purpose they can be injected through different gates which are suitably positioned (alternatively through one common gate). The method produces the two flow fronts moving as nearly as possible in opposite directions (A and B). The example shown forms one point front penetrating the other angular front (1) for their overlap. ADVANTAGE - The two-part (for example) mouldings are produced in one operation. The joints made have high mechanical strength

Title: Non-destructive testing of plated workpieces by pulse-echo process - using at least three ultrasonic oscillators to produce transverse waves of 2 mHz and incident angle of 40 deg. on non-coated side
Inventor: BOERNER STEPHAN
IPC: B06B1/06
Filed: 1991-06-06
Abstract: A max. structural noise is generated, the reflected noise level then being used as a parameter for locating fault spots. At least three ultrasonic oscillators (3) are arranged on a plexi-glass base piece (2). This allows transverse waves at a frequency of 2 MHz and an incident angle of 40 deg. to be propagated from all spatial directions on the non-plated side of the workpiece. The noise signal level from each direction is digitally stored, registered, normalised and compared with each other. A signal level comparison is also made for each registered workpiece vol. element. Size, position and form of any fault point are calculated from the various noise signal levels. USE/ADVANTAGE - Welded seam, pressure container, stern of ship. Textural or join noises no longer interfere with evaluation of echo signals since the level of the intercepted noise itself serves as the parameter for detection of faults.
