Title: An improved method of and means for altering the physical structure of metals by mechanical treatment
IPC: C21D7/04
Filed: 1938-04-29
Abstract: 492,089. Altering physical structure. JULIEN, J. D. April 29, 1938, No. 12822. [Class 83 (iv)] The surface of metal in the form particularly of cast sleeves and like hollow or tubular parts for aircraft &c. engines made of austenitic or similar material is mechanically treated by first forming ribs or protuberances thereon and subsequently depressing them. This produces a sort of kneading action on the metal. As shown, a pair of dies 3, 4 has corrugations, which are out of phase with one another. After making one set of corrugations on the work and turning the dies around the corrugations may be displaced and formed in another position. The dies may be replaced by rollers.

Title: Improvements in brake operating apparatus
IPC: B60T11/10
Filed: 1949-05-16
Abstract: 665,491. Fluid-pressure-operated brakes. NEALE, F. May 15, 1950 [May 16, 1949], No. 12934/49. Class 103 (i). In a brake apparatus a manually operated mechanical means for applying some or all of the brakes is adapted on initial application movement to effect operation of fluid pressure power means to apply some or all of the brakes, and is also adapted on further application movement to effect release of said fluid pressure power means so that some or all of the brakes may be solely further operated by said manually operated mechanical means. A hand lever, illustrated diagrammatically at 1, Fig. 1, moves horizontally a cam 20 on a member 16 by means of a bracket 5, a spring-loaded detent 8, rod 6, arm 10, shaft 13, spur-wheel 14 and rack 15, the direction being shown by arrows. A cam 19 on a vertically slidable member 18 operates, through a spring 30 and a lever 22, a fluidpressure regulator such as that shown in Specification 606,410, [Group XXIX]. Operation of the hand lever 1 causes the cam 19 to ride up the cam 20, the fluid pressure in the braking system increasing until the face 25 of cam 19 drops suddenly over the vertical face 26 of cam 20 and releases the fluid pressure brake. Further movement of the hand lever operates the mechanical brake only, the movement being permitted, after engagement of the stop 27 and body 17 of member 18, by disengagement of the detent 8. To prevent operation of the fluidpressure regulator on return of the hand lever to the " off " position, the cam faces 25, 26 are inclined laterally of the member 16 to force the member 18 sideways against a spring (Fig. 3, not shown) thereby allowing passage of the cam 20. The brakes are preferably in accordance with Specification 588,036. It is stated that the mechanical operating means may include hydraulic transmission.

Filed: 1972-03-20
Abstract: 1391724 Projection printing electrophotographic apparatus VARIAN ASSOCIATES 20 March 1972 [22 March 1971] 12945/72 Headings G2A and G2H In an electro-photographic recording apparatus wherein the image of an original 16 to be copied is projected through a glass plate 12 on to a photo-conductive plate 10, a web of recording paper 20 is periodically brought into pressure engagement with the plate 10 by a pivotally mounted pressure pad 58. The pivotal axis 56 of the pad is such that the web is first pressed at a point close to the axis and so that the area of engagement increases in a direction away from this axis thus ensuring a smoothing action. The pad is pivoted by a motor 50 operating through a toggle linkage 54. Limit switches 64, 74 control operation of the motor 50 and the web transport motor 38. When the pad is in pressure engagement with the web a pawl 70 engages a ratchet 72, to lock rollers 66 and 68 and hold the web taut. During exposure the web is subjected to an electric field between an electrode 28 and the pivoting assembly 24. In an alternative embodiment Fig. 3 (not shown), the pad 58 is housed transversely of the direction of web transport to permit lateral expulsion of air as the pad engages the web. In a further embodiment the pivotal axis is made non- parallel with respect to the plane of plate 10 so that engagement with the web starts at one corner of the pad thus assisting expulsion of air.

Abstract: 628,465. Making foam. ROCKWOOD SPRINKLER CO. OF MASSACHUSETTS. April 30, 1946, No. 12999. Convention date, May 8, 1945. [Class 47 (ii)] A foam generating nozzle comprises an inlet section 12 for foaming liquid, a hood 20, and a curved jet plate 10 formed with diverging orifices 14 each comprising two inclined passages 16. Liquid under pressure forced through the orifices is converted into a mist of fine droplets which entrains air through apertures 22 in the hood to form foam, the latter being refined by passage through a grid or screen 36 with a mesh of three to ten per inch. Preferably, a plate 24, with holes 32 aligned with the orifices 14, is spaced from the plate 10 so that some of the air entering at 22 is diverted into close association with the orifices 14. Liquid pressures greater than thirty pounds per square inch and air-toliquid ratios between five and eight to one are used. The nozzle is intended to produce a broadly divergent discharge of foam capable of blanketing a large area of fire and of shielding the operator of the nozzle from the heat. A concentrating extension hood may be provided, which first converges from the hood 20 and then is cylindrical. The nozzle may be used for producing an extinguishing mist or fog of water alone. Specifications 403,291 and 564,199, [Group XXIX], are referred to.

Title: Improvements in or relating to metal hose clips
IPC: F16L33/08
Filed: 1945-05-28
Abstract: 593,258. Clamping-rings. MILLERET, P. E., and HUNT & TURNER, Ltd. May 28, 1945, No. 13285. (Class 44] A metal hose clip has a cylindrical-shaped housing 3 to which one end 2 of a band 1 is secured, the other end 4 having serrations 5 for engagement by a worm or screw 9 which is so mounted in the housing that when turned to expand the band, it moves axially until disengaged from the serrations. Preferably the worm has a plain extension 12 passing freely for sliding and rotary movement through the bore in a washer 8 which is secured, e.g. by clinching, to one end of the housing 3. A collar 14 is secured to the free end of the extension and contacts the washer 8 when the worm is disengaged from the serrations. The housing 3 surrounds the worm over more than five-eighths of its circumference to prevent rocking, and has on its underside a casing 6 of rectangular crosssection for the ends 2, 4 of the band 1. The head 10 of the worm 9 bears against the end of the housing 3 when being turned, whereby the thrust is taken directly by the housing. To slacken the band 1 considerably, the worm is turned counter-clockwise while pressure is applied to the end 15 of the extension 12 until the worm is disengaged from the serrations 5, retaining the pressure on the extension. The end 4 of the band 1 can then be drawn through the casing 6. To tighten the band again, pressure is removed from the extension and applied to the worm head 10, the worm being turned clockwise to re-engage the serrations. It is thus unnecessary to provide serrations to the end of the band, and insertion of the end 4 into the casing is facilitated, the worm being moved axially into engagement with the serrations. Reference has been directed by the Comptroller to Specification 586,235.

Title: Improvements in gyroscopic apparatuses for automatic steering of torpedoes, aircraft, ships and the like
IPC: F42B19/01
Filed: 1935-05-07
Abstract: 448,959. Automatic control systems. ELIA, G. E., 9, Via S. Valentino, Rome. May 7, 1935, No. 13414. Convention date, May 7, 1934. [Class 38 (iv)] Path of a moving body.-Relates to an automatic steering device for torpedoes, aircraft, ships, and the like of the type in which a gyroscope carries a movable member adapted to cooperate with contacts carried by the vessel, thus controlling an electric motor so as to operate the rudder to keep the vessel on the course it is pursuing at any instant. According to the invention, a film having perforations is adapted to pass electrical contacts which thus momentarily make circuits through electromagnets to cause a displacement of the member carrying the gyroscope-operated contacts, so that the electric motor is energized to produce predetermined changes in the general outline of the whole course of the vessel. In the form shown, a shaft 16, Fig. 1, is biassed in one direction by a spring 18 which is constantly kept wound up from the main drive. The shaft 16 carries planets 25 engaging a loose double bevel wheel 26 and a bevel wheel 23 on an intermediate shaft 23a, which carries planet wheels 25<1> meshing with the double bevel wheel 26 and with a bevel wheel 29 connected to a gear 30 which rotates the member carrying the gyroscopeoperated contacts. The shaft 23a carries an escapement wheel 27 and the double bevel wheel 26 an escapement wheel 26<1>. The escapement anchors are operated by electromagnets, not shown, energized by the film actuated controlling-device shown in Fig. 4. When one escapement is acting, the other acts as a .stop, and according to which escapement is operative the driven gear 30 rotates in one direction or the other. The film 35, Fig. 4 is wound from a reel 39 to a reel 40 by a sprocket 34, and passes over a guide pulley 45 and a fixed metallic guide 46. A series of spaced holes in the film permit one of a pair of contacts 37 to pass through and touch the member 46 thus energizing one or other of the electromagnets which operate the escapements.

Abstract: 1436914 Television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 March 1974 [30 March 1973] 13432/74 Heading H4F A video signal Sa produces by scanning a sequence of images is recorded on a tape-shaped record carrier 1 in the form of cinematographictype images by means of P record heads each having x electrodes arranged in a line at right angles to the direction of record carrier movement, the electrodes in each head being staggered with respect to the electrodes in the other heads (e.g. as shown in Fig. 2 for four heads). The video signal samples produced by gates 7 from a line scan video signal being sequentially fed to the first electrodes of each head and then sequentially fed to the second electrodes of each head &c., and finally sequentially to the xth electrodes of each head. This is repeated for each of the n lines of the first images video signal so that this first image signal is recorded as P partial images 2(1)-2(P) on the record carrier. The next image signal is then recorded as P partial images on the record carrier but one image frame distance d displaced from the first image signal P partial images so that (P-1) recorded image frames have interlaced dot information from both image signals recorded thereon. Thus after the Pth image signal has been recorded, one recorded image frame contains interlaced information for all P image signals and subsequent recorded image frames will also contain interlaced information from P image signals. With four record heads, each a recorded image frame distance d apart, the electrodes may be arranged in the staggered sequence 1324 as shown in Fig. 2 or in the sequence 1234. The record carrier specifically comprises an electrosensitive carrier tape comprising opaque or transparent paper having a metal layer which is burnt off by contact with an electrode to which electric current is supplied. The frequency at which image frames are successively formed on the record carrier remains equal to the frequency of the image signals to be recorded thus if a television signal having a frequency of 50 fields/sec. (25 images/sec.) is recorded using four heads each recorded frame contains information from four successive fields (i.e. 2 images) and the recorded carrier may be projected at 50 images (frames) per second.
