Title: Improvements in or to umbrellas
IPC: A45B25/06
Filed: 1969-09-16
Abstract: A shortenable umbrella frame comprises a stick, ribs pivotally connected to a crown, main struts pivotally connected to the ribs and to a first slider, and auxiliary struts pivotally connected to the main struts and to a second slider which has projections which are spaced angularly and extend radially outwards with respect to the stick axis and to which the inner ends of the auxiliary struts are pivoted, so that when the frame is closed either the ribs or main struts nestle relatively to the projections from the second slider or relatively to recesses between the projections. In a first embodiment, Figs. 2-10 (not shown) and Fig. 1, a main slider 7 and an auxiliary slider 8 slide on a two-part telescopic stick 1 of hexagonal section and having a crown 9 to which are pivoted ribs 11 having inner parts a with a U-shaped section within which outer parts b slide, parts b being secured to sleeves 17 sliding over parts a. The flattened inner end of each auxiliary strut 13 is pivoted on a pin 22 between projecting wings (20), Fig. 3, of slider 8, pins 22, wings (20), and the body of slider 8 being integrally moulded in a plastics material. When the umbrella is collapsed inner and outer parts of the struts 13 and the wings (20) are received within recesses in struts 12 which have a U-shaped section, struts 13 being bowed with their central parts abutting the stick 1, and outer parts of struts 12 being received in recesses in the members 17 to which they are pivoted, members 17 having a U-shaped section over at least part of their length. On releasing the umbrella from the collapsed state the energy stored by the bowing of struts 13 automatically partially opens the umbrella, Fig. 10. In a second embodiment, Figs. 11-13 (not shown) recesses 51, 52 are formed in flanges 48, 50 respectively in auxiliary and main sliders 41, 46 respectively to receive parts of telescopic ribs 36, 37 when the umbrella is collapsed, the recesses 51 being aligned axially, with respect to the stick axis, with recesses 52.

Title: Improvements in ultrasonic delay lines and methods of and apparatus for manufacturing the same
IPC: H03H9/36
Filed: 1969-11-10
Abstract: A method of manufacturing a plurality of strip delay lines comprises the steps of: forming a stack of strips of a material through which ultrasonic waves may be propagated grinding surfaces of the stack to form input and surfaces on the strips securing plated pieces of piezoelectric material to the ground surfaces of the stack and separating the delay lines from each other by forming slots in the said pieces at positions situated between the strips. One embodiment of an individual delay line, Figs. 1a 1b, comprises a steel-nickel alloy strip 1 having a thickness less than one half of the wavelength of the signal to be propagated, the ends of the strip having piezo-electric bars 2 soldered thereto, the length h of the bars being less than the width I of the strip. The bars 2, polarized to operate in the shear mode, are plated with an electrode along the long edge in contact with the end of the strip and also along the opposite outward facing edge, leads 12, 13 making connection with the electrodes. The long edges of the strip 1 have absorptive tapes 3 applied thereto. In another embodiment, Fig. 2, the strip 8 has a dihedral edge supporting transducers 9 and the opposite edge 11 acts as a reflector, the other edges of the strip having absorptive tapes 10. In the manufacturing method, Fig. 4, a plurality of steel strips 21 separated by spacers 22 are temporarily clamped together to form a stack and those faces of the stack to which the piezo-electric plates 26 are to be soldered, are trimmed by grinding. Fig. 4 shows a single plate 26 having metallized opposite faces 25, 27, the face 27 being secured by a solder joint 28 to a ground face of the stack. The face 25 has an electrical connection in the form of a foil 24 and another foil 23 is soldered to the strips 21. The individual delay lines are produced by a frame saw having cutter wires 29 which saw into the spaces formed by the spacers 22. In a modification (Fig. 5, not shown), the cutter wires 29 are replaced by diamond cutter disc. The steel strips are dimensioned to have a delay time slightly less than the desired value, the final value being achieved by mechanically deforming the strips over a localized area by a hammering operation (Fig. 6, not shown), by a rolling operation (Fig. 7, not shown) or by a stretching operation (Fig. 8, not shown). The delay line strip 59 may be subsequently bent into the shapes shown in Figs. 9, 10.

IPC: C08F2/00
Filed: 1971-03-06
Abstract: A process for the high pressure polymerization of ethylene in an autoclave reactor is disclosed, wherein the autoclave contents are maintained in a thoroughly mixed condition by converting the pressure energy of the ethylene feed into kinetic energy by throttling the flow of ethylene feed into the autoclave, to create a turbulent flow wherein the Reynolds number exceeds 2100, to produce macroscopic circulations in the autoclave. Such a process has numerous advantages, primarily in the reduction of the number of explosive decompositions of ethylene. Apparatus for conducting such a process are also disclosed, wherein such apparatus includes an autoclave having at least one ethylene feed inlet which imparts a rotary motion to the autoclave contents.
