Title: Continuous cropping of strip - cropping tool moves with velocity of strip during cut-off with error minimised by P-I control
IPC: B23D36/00
Filed: 1974-04-04
Abstract: The continuous cropping of strip matl. travelling at a constant velocity is facilitated by the use of proportional-integral controller coupled with velocity feedback. The strip is fed through a cropping station mounted on a roller mounted base that is actuated by a double acting hydraulic cylinder under servo valve control. A position transducer supplies information to the P-I controller which is coupled to a summing junction. The summing junction also receives a velocity signal from a tachogenerator driven by a friction wheel in contact with the strip. When the strip contacts the plunger and moves to the nall position the integral control action operates to reduce the error to zero. The hydraulic actuator moves the base until the velocity is equal to that of the strip, at which point cropping occurs.

Title: Sulphuric acid prodn. by contact method - by roasting sulphide ore, scrubbing and electrostatically purifying gases, and contact oxidation
Inventor: FENNEMANN WOLFGANG
IPC: C01B17/56
Filed: 1974-04-08
Abstract: Sulphuric acid is produced by the contact method by heating a sulphide ore in a reactor, scrubbing the gases with spent sulphuric acid soln. contg. metal sulphates, and oxidising the purified SO2 on a contact catalyst. The scrubbing is carried out in a venturi washer, then the gases are indirectly cooled to the dew point, the sulphuric acid mist and dust, (if present) are removed in a wet electrostatic gas purifier, the gases are passed again through another cooler and purifier to the contact catalyst station, whilst condensates from both stages are recycled. The spent sulphuric acid contg. metal sulphates is thus economically utilised. SO2 is purified to the degree required for the content process.

Title: Laminated film for packaging - weldable at low temps is hot melt-applied to a plastics etc. carrier
Inventor: BUEHRER HEINRICH GEORG DR
IPC: B65D65/40
Filed: 1974-07-16
Abstract: A laminated film consists of a plastics carrier (I) coated with a compsn. contg. a copolymer (II), paraffin and/or wax and/or a resin which compsn. is economically weldable at temps. of above 100 degrees C. Used in the prodn. of flat packages (e.g., for cheese, sausage etc.) or, opt. in combination with a metal or plastic film or paper, as lids for containers (e.g., cream, yohurt, etc.). Previous matl./coatings were oly weldable in relatively narrow temp. ranges which had to be closely controlled so that the containers were tightly sealed yet not so tightly that they became difficult to open by hand. Temp. of 200-250 degrees C had to be used in high throughput machinery which gave rise to thermal losses at the welding head and exposure of the printing dyes to a great deal of heat. This is overcome by using lower temps. and broader welding temp. ranges. As the coating is pref. hot melt applied, there is no solvent odour problem. Packages formed have a more convenient and constant tear-open strength.
Patent DE-2437339-A1 (DE)
Title: Switch circuit for electrical lamp appliance - uses acoustic signal and has transmitter and receiver connected to thyristor
Inventor: PAPP GEORG
IPC: H03K17/94
Filed: 1974-08-02
Abstract: The receiver (12) may be coupled with the control input of the thyristor (8) which on one side receives voltage from an impulse relay (7), and a storage capacitor (13) is arranged in parallel to the receiver and is charged via a device consisting of a diode (11) and a capacitor (10) in series. This series connection has a high resistance that the charging up time of the storage capacitor (13) is large in comparison to the vibration time of the receiver. A dim-light control (5) is provided which turns off the switch arrangement when loaded with light (7) of a predetermined intensity. The design of switch avoids the danger whereby it is continuously switched on and off due to feed-back coupling between an impulse relay and the acoustic receiver.
Patent DE-2439988-A1 (DE)
Title: Automatic fault detection on smooth curved surfaces - using laser scanning technique and suited to coachwork testing
Inventor: HOVE HERWIG VAN
IPC: G01B11/25
Filed: 1974-08-21
Abstract: A device for testing smooth, curved surfaces, such as the coachwork of vehicles, and which depends on a laser beam scanning of the surface to detect faults in it, is presented. The apparatus consists basically of a laser source and scanning arrangement which directs a beam in a number of parallel lines over the surface to be tested. The reflections of this from the surface are monitored by a television camera and analysing unit. The criterion by which the analysing unit tests the surface concerns the separation of the canned lines from the surface, and any deformation results in a reduction of this separation at some point.
