Title: Method of bonding epoxy resin
IPC: B29C65/06
Filed: 1978-11-10
Abstract: Objects made of cured epoxide resin are bonded together by   a. placing the two objects in contact with each other at substantially planar mating surfaces, b. applying a static force to the objects to urge them into intimate contact with one another at the mating surfaces c. subjecting these surfaces to motion, relative to one another, by rotation or vibration, for a sufficient period for the frictional energy between these surfaces to heat them above the glass transition temperature(s) of the objects, and d. stopping the relative motion whilst maintaining the static force until the mating surfaces have cooled to below the glass transition temperature(s) of the objects.   The method may be used with objects having a glass transition temperature of from about 40 DEG C to 200 DEG C, and provides a satisfactory bond within seconds, i.e., more rapidly than does the conventional method of applying a liquid curable adhesive composition and allowing this to cure.

Title: Electronic noise suppressor circuits
IPC: H04B15/00
Filed: 1978-12-14
Abstract: In an audio system the switching of an A.C. waveform generates high frequencies which result in unwanted noise, the invention eliminates this noise by detecting in a detector (4) the zero voltage points of the A.C. waveform and controlling an electronic switch or other device (2). The control signal from a source (5) to the switch (2) is released from a store (6) only at a zero voltage point so that an abrupt, high- frequency noise pulse is avoided. <IMAGE>

Title: Method for feeding livestock with concentrated fodder and apparatus for carrying out the method
IPC: A01K5/02
Filed: 1979-03-07
Abstract: Cattle, pigs, etc., are fed with fodder concentrate according to a feeding estimate adjusted to each animal or group of animals. On every feeding occasion, every animal is given a portion of concentrate composed of a predetermined number of concentrate packages, all of them containing the same quantity of concentrate which is from 0.5 to 2 kg, preferably 1 kg. The animals are fed on several occasions around the clock so that the total weight of the concentrate allotted to each animal will correspond to its estimated need of concentrate. The feeding programme may extend over a period of several days. The fodder is preferably packed in bags made of pure paper. An apparatus for carrying out the method is also described in which the concentrate packages are automatically fed under programmed control to each animal from a hopper to a feeding table. A cutting device can rip the package open immediately it arrives on the feeding table. <IMAGE>

Patent GB-2019773-A (GB)
Title: A Baling Press
IPC: B30B9/30
Filed: 1979-04-27
Abstract: A baling press has a press plate (20) movable up and down in a container in relation to a base plate for compacting paper waste for baling. A device for discharging a bale through a door (14) of the container has an angled pull rod (34, 35, 36) with one leg (36) connected pivotally (33, 37) to a rockable bottom part (30) pivotally mounted (31, 32) to the frame of the press. The other leg (35) of the pull rod has a hook (38) engageable with the press plate (20). When the press plate (20) is raised after compaction of a bale it lifts the pull rod (34) which in turn causes the bottom part (30) to rise as shown, in dashed lines. The initial movement of the bottom part (30) is caused by abutment of the pull rod against a projection (41) on the bottom part, providing increased force for the initial breaking away of the highly compacted waste from the internal walls of the container of the press. When the door (14) is closed, a rod (43) acts on the pull rod (34) to hold the hook (38) out of engagement with the press plate. The press plate and the hydraulic cylinders which move it are mounted on a carriage movable to a position clear of the container. <IMAGE>

Patent GB-2027887-A (GB)
Title: Improvements in or relating to methods of non-destructive testing
IPC: G01N29/06
Filed: 1979-06-14
Abstract: In a method for ultrasonically testing a generally opaque solid (18') a transducer (19) sets up ultrasonic vibrations within the solid. A surface of a visualising medium (14) is placed in acoustic contact with a surface of the solid to thereby establish an ultrasonic stress wave pattern in the visualising medium. This pattern may be visualised by providing stroboscopic illumination and visualising optics (Fig. 1, not shown). Fringes may be interpreted to indicate the presence and nature of structural defects within the solid. A defect (31) produces circular families of fringes (30a, b). <IMAGE>

Patent GB-2030433-A (GB)
Title: Spreader
IPC: A01C15/10
Filed: 1979-07-27
Abstract: A spreader for distributing granular or finely-divided material has a hopper 10 mounted on ground wheels 12, 12'. The wheels reciprocally drive an apertured belt 14 which conveys material horizontally from hopper outlets to apertures 13a in a material support plate 13, through which the material can fall to the ground. Since the plate 13 is screened from the direct gravitational flow of material from the hopper, the spreader distributes material only when the ground wheels are rotating. By adjustment of the belt drive mechanism, the stroke of the reciprocatory movement of the belt can be varied to vary the rate of distribution of material relative to the rotational speed of the ground wheels. A material stirrer 25 within the hopper 10 is also driven by the ground-wheels 12, 12'. <IMAGE>

Title: Magnetic catch eg for clothes washing machines
IPC: E05C19/16
Filed: 1981-02-17
Abstract: A magnetic catch for a domestic appliance having a door and a double-walled external panel hinged to the casing of the appliance to cover said door, comprises co-operable first and second magnetic members (32, 9) respectively disposed in the panel (5) and on the casing (8). Pivoted within said panel (5), a lever (16) carries a suction member (19) at its free end and is engaged by sliders (27), bearing spring-loaded stud (26), and also magnetic member (32) via a pin and slot. Spring (36) urges lever (16) clockwise, and its force combined with that of the magnetic attraction overcomes spring (28). To open from the closed (Fig. 2) position, panel (10) is depressed, forcing lever (16) to turn anti- clockwise and attaching sucker member (19) to the panel. The total force of suction and spring (28) overcomes the spring (36) and the magnets, turning lever (16) and opening the magnetic catch so that panel (5) pops open. The controlled leakage of air eventually releases the sucker and permits re-closing. <IMAGE>
