Title: An improvement in or relating to the welding of tubes to tube plates
IPC: B23K9/028
Filed: 1980-05-09
Abstract: A method of bringing a welding head (10) into exact alignment with the bore of a tube when welding tubes to tube plates. In order that the welding head (10) can be positioned independently of the work, the method includes the step of bringing a datum or probe member (22), offset by a fixed distance from the axis of the welding head (10) into alignment with the axis of the tube and the further step of moving the datum or probe member (22) and said welding head (10) through said fixed distance to bring the welding head (10) into the position previously occupied by the datum or probe member (22) and into alignment with the axis of said tube. <IMAGE>

Title: Improvements in or relating to blowers for through-flowing abrasive materials
IPC: F04D29/22
Filed: 1980-06-17
Abstract: This invention relates to blowers for through-flowing abrasive materials e.g. milled cereals, of the kind having a plurality of vanes or blades 5 which are mounted on a driving shaft 1 and are impinged by flow substantially radially from the inside towards the outside and arranged to feed the material to a tangential outlet 6 leading to a conveying duct. According to the invention, the surface of each blower vane 5 facing in the direction of rotation has secured to it at least one bar 11 which is at least approximately parallel to the driving shaft 1. This bar, or that bar placed in the radially outermost position, is situated close to the axially parallel external edge of the blower vane. Preferably the or each such bar 11 forms the external edge of its blower vane and may be formed by bending over the peripheral edge of its blower vane in the direction of rotation. <IMAGE>

Title: Thrust producing device for overload release clutch
IPC: F16D43/206
Filed: 1980-12-02
Abstract: A thrust producing device has at least one pair of balls or rollers 16 in contact with each other contained in a bolt 15 surrounded by a resilient ring 17 applying opposite forces at two contact points about a line offset from the line joining the ball or roller centres. A third force (acting on a ball 18) is generated at right angles to the said two opposing forces substantially friction free due to the contra-rotating rolling action of the balls or rollers in contact with the resilient member. The profile of the inner surface of the resilient ring is shaped so as to control the magnitude and direction of the resultant force when relative movement occurs between the bolt and the resilient ring. In certain embodiments this movement is used to disengage the halves 13, 14 of a rotary torque transmission device when overload occurs. <IMAGE>
Patent GB-2070648-A (GB)
Title: Washing machine
IPC: D06F34/18
Filed: 1981-01-22
Abstract: The programme of an automatic washing machine is controlled according to the type of articles to be washed. The machine incorporates a pressure-operated control device 3 for measuring the water level in the machine and a magnetic valve 6 for controlling the water supply, which device 3 and valve 6 are connected to a central processor unit 4 which can thus determine the quantity of water supplied and determine the further program operations to be performed. In operation, for the pre- wash, water is supplied until the level reaches N1 and the valve 6 closes. Reversing washing movement of the drum 1 commences so that the washing absorbs water dependent upon the absorbability of the fabric thereof. The water level drops and, when it reaches level NR, the valve 6 opens to restore it to the level Ni. This re-filling may be repeated several times. The quantity of water supplied during the pre-wash constitutes a gauge for subsequent operations. <IMAGE>
Patent GB-2071818-A (GB)
Title: Improved compressor valve having annular valve elements
IPC: F04B39/10
Filed: 1981-03-06
Abstract: An improved compressor valve structure is disclosed, of the type in which one or more annular valve elements (52, 54, 56, 58) seal against annular seating surfaces (28, 30). The valve elements are biased into contact with their seating surfaces by resilient means (60, 64) which also cooperate with the neighboring valve guard structure (62, 63, 72) to fluidically dampen movement of the valve elements once they have left their seating surfaces. A curved contact element (64) between the valve elements and their retaining springs (60) allows the valve elements to flex or roll as necessary to accommodate differential thermal expansion of the valve seat, valve guard and valve elements so that effective sealing still can be achieved. The valve elements include a flow balancing ridge (82) on their high pressure sides, to direct fluid flow more evenly to both sides of the annular valve elements. <IMAGE>

Patent GB-2076122-A (GB)
Title: Fluid pressure control valves
IPC: B60T15/02
Filed: 1981-04-15
Abstract: The pressure of fluid passing from a throttled inlet 2 to an outlet 4 is controlled by a vent valve 12 which is biassed closed by a pivoted beam 25 subject to a variable electromagnetic force. The beam is statically counter-balanced by weights 26 and is supported by a resilient metal strip which allows limited angular movement of the beam about its support at 24. The combination of static balance and resilient support renders the valve substantially insensitive to shock forces acting through the support point. <IMAGE>

Title: Worm conveyor for objects, such as shaped bottles
Inventor: BOMS HERMAN
IPC: B65C9/02
Filed: 1982-08-03
Abstract: Bottles, square (or triangular), are held positively in the worm thread by a guide extending along the section and are conveyed along the worm as the worm rotates. As shown, located at the outlet of the worm is an inlet drum with compartments (6) arranged on the outer periphery and adapted to the shape of the bottles to which the worm transfers the bottle. In the transfer region, the worm conveyor (10) in conjunction with guide (8) gives the bottles such a lead, or such a lag with respect to the locations (6) of the inlet drum, that the corners of the objects can be transferred in synchronism into the locations (6) without colliding with the inlet drum. Alternatively, in the transfer region, the radial support face of the worm thread of the worm conveyor may have a radial height increasing in the direction of the inlet drum so that the bottles can be transferred in synchronism without any collision of their corners with the inlet drum into the locations of the latter. <IMAGE>

Title: Data storage unit
Inventor: DELAHUNT STEPHEN JAMES
IPC: G11C11/4076
Filed: 1983-10-07
Abstract: In a data storage unit, internal timing signals RAS, CAS, etc. are produced by scanning a writable control memory 21. Thus, the timing of the storage unit can easily be varied, simply by re-writing the contents of the control memory. This allows the use of a faster clock rate without the necessity for complete redesign of the storage unit. The basic clock period at 31 is sub-divided by shift register 30 into a number of sub- periods, allowing the timing signals to be adjusted with an accuracy better than one clock period. The sub-period clock signals, C0-C3, are selected by gates 32-34, which receive also the contents of registers 35-37, and are combined in gates 24-29 with the scanned memory 21 contents to generate the timing signals. <IMAGE>
