Abstract: 1,052,910. Woodworking. F. MEYER & SCHWABEDISSEN. Nov. 19, 1965 [Sept. 29, 1965], No. 49323/65. Heading B5L. An end profiler comprises a milling tool 2 which is associated with a longitudinal conveyer 1 for a plurality of workpieces 7 to be machined in succession and cooperates with a counter profile 4, and a drive 5, 6 which constantly applies the profile against the particular workpiece approaching the milling tool and restores it to an initial position after the machining thereof. The counter profile 4 is mounted in a holder 3 which is movable by a lifting device 5 and a pushing device 6 of the drive to position the counter profile at the back of a workpiece 7 as it is carried on the conveyer past the milling tool to avoid tearing the wood fibre, the devices 5, 6 then being operated to lower and return the profile so that it may be engaged with the next workpiece and the tool rotating in a direction opposite to the direction of movement of the conveyer to press the workpieces against the counter profile. In another embodiment, the counter profile is positioned in front of the workpieces and the cutter rotates in the same direction as the movement of the conveyer. In a further embodiment, the counter profile is mounted on a swivel arm.

Title: Improvements in or relating to the production of weather charts
IPC: G01D9/28
Filed: 1963-12-23
Abstract: 1,062,640. Recording-apparatus. R. HELL. Dec.23, 1963 [Dec. 24, 1962], No.50684/63. Heading G1J. A system for recording a weather chart representing the spatial distribution of a meteorological quantity, for example atmospheric pressure, comprises an electronic computer store at a central weather station, in which pressure values supplied by observation stations are stored in conjunction with geographical co-ordinates of the stations and are interpolated for other co-ordinates, and means whereby the pressure values at selected points may be transmitted to a receiving station to be rapidly recorded and then transformed into a visual record on a chart. To keep the transmission time to a minimum the interim record at the receiving station is made magnetically on a drum or tape or electrostatically on an insulating support. The values may be transmitted electrically with amplitude, frequency or pulse-code modulation. The points whose pressure values are to be transmitted may be selected:- (a) to produce isobars for which the computer will give the co-ordinates of all points at which the pressure is the same as a selected value fed to it and will repeat the process for say 5mb. intervals. (b) to lie along the course of a ship or aircraft. (c) along successive, parallel and equidistant co-ordinate lines of a network. The final visual record can take various forms:- (a) Where an amplitude-modulated signal has been made on a record support in sheet form so that the magnetic or charge density is proportional to pressure, the density distribution may be made visible and fixed by the methods of ferrography or zerography. (b) The interim store may be scanned to feed signals to a picture telegraphy receiver to record the pressure distribution point by point and line by line in the form of variable shades so that high pressure areas are reproduced as bright spots and low pressure areas as dark spots and the pressure represented by each shade of grey may be read from a pressure scale printed on the chart against the steps of a grey scale. (c) A similar record may be made by feeding the scanned signals to a photographic receiver to control a shutter determining the size of a light spot to be recorded. (d) Isobars may be recorded by feeding the appropriate signals to a facsimile receiver, the signals being selected before transmission or from the interim store at the receiver by using a comparator circuit to compare scanned voltages with the 22 discrete voltages proportional to multiples of 5mb. in the range 960 to 1066mb. (e) In prints in variable density of isobar form, signals derived from the interim store can be made to control the depth of penetration of an engraving tool'into the surface of a printing block. (f) A transient record can be shown on a form of cathode ray tube. (g) The pressure variation along a predetermined course can be plotted by feeding signals derived from the Interim store to an electromagnetic graph recorder to plot pressure against distance along the course.

Abstract: 1,160,350. Moulding pneumatic tyres. UNIROYAL, Inc. 9 Nov., 1967 [22 Nov., 1966(2)], No. 50972/67. Heading B5A. In a method and apparatus for cooling a pneumatic tyre during a post-inflation treatment after removal from a moulding press, jets of cooling air are directed on to the tyre, the temperature and flow rate thereof being such as to achieve a rate of heat transfer from the tyre to the air of between 15 and 70 B.T.U./hour/ square foot of tyre surface area/degree fahrenheit of temperature difference between the tyre surface and the air. The air may be taken directly from the curing room atmosphere or it may be cooled. In one embodiment, after removal from the press, the tyre T is received on a chuck 22 at the end of an arm 23 pivoted at 23a, it is then inflated and swung by a pressure cylinder 29 into the stationary half 31 of a cooling structure; the other half 32 is then lowered to surround the tyre whereupon jets of air flow from parallel rows of orifices 45 located around the cylindrical inner wall 36 of the structure. The latter is supplied by a blower 43 which feeds the halves via ducts 42 and 50; the ducts supply a chamber 37 of each half via a perforated wall 38 and an outermost wedge-shaped chamber 41. In a modification, Fig. 5, not shown, the cylindrical perforated inner wall of the structure has frusto-conical surfaces (53, 54) extending radially-inwardly therefrom and provided with rows of outlets (57, 58). In the embodiment of Fig. 6, a quadruple postinflation equipment 21a is provided, and includes two pairs of post-inflation chucks 63, 64 pivoted about an axis 66 so that one or other pair, with inflated tyres attached, is raised into, or lowered from, a pair of cooling chambers C2 located side-by-side and supplied with cooling air by a blower 92 and a common supply duct, The cooling structure is carried by arms 71 pivoted at 73 to a framework 100, so that it can be raised and lowered by pressure cylinders 77. When tyres on the uppermost chucks are being cooled, those on the lower ones, which have been cooled, are removed and carried away by conveyers 62, 99. Tyres from the press are carried by conveyer 62 to the lower chucks and inflated whereupon when the cooling on the upper chucks is concluded the cooling structure is raised, the lower chucks swung upwardly and the structure lowered to begin a further cooling operation. The air jet outlets may be comprised by rectangular openings of flat nozzles arranged transversely to and directed obliquely toward the tyre tread. The cooling structure may be comprised of axially separable halves combined with a tyre chuck arrangement in which each chuck half is attached to a chamber half.

Abstract: 1,152,098. Stud welding. OMARK INDUSTRIES Inc. 13 Nov., 1967, No. 51466/67. Heading B3R. A stud welding machine comprises an actuator 60 serving to actuate a stud holder 12 to grip the stud 14 while the holder is moved toward the workpiece 16 by a resilient drive 22 and operable by inertia after the stud has engaged the workpiece to cause the holder to release the stud before rebound of the holder occurs. The actuator 60, which is slidably keyed to an adapter sleeve 30 and which has a weighted head 70, is provided with spring fingers 91, the tips 90 of which engage-in the studgripping position shown-portions 92 of a split collet 42 having four spring fingers 84 to urge the gripping surfaces 86 of the fingers 84 into tight engagement with the stud. As the holder 12 is moved rapidly towards the workpiece by the resilient drive 22, e.g. a pneumatic cylinder device, an arc is drawn between the tip 108 of the stud and the workpiece, welding current being derived from a capacitor 110. Upon impact of the stud on the workpiece the inertia of the actuator 60 causes it to slide downwardly, i.e. towards the workpiece, whereby the tips 90 of spring fingers 91 move to a position adjacent cylindrical portions 94 of the collet spring fingers 84, the diameter at portions 94 being less than at portions 92, whereby the fingers 84 spring open and release the stud before the holder 12 rebounds from the workpiece. An additional weight may be attached below the actuator head 70. The collet 42 is of phosphor bronze.
