Title: Machine for die casting or for casting metal under pressure in metal moulds
IPC: B22D17/04
Filed: 1921-09-26
Abstract: 169,461. Prõzisionsguss-Fabrik Geb. Eckert. Sept. 25, 1920, [Convention date]. Casting-machines; metal-pouring; castings, extracting; moulds; clamping moulds. - A diecasting machine is provided with improved means for heating the melting-pot and for adjusting and replacing certain parts. The melting-pot 8, Fig. 3, is carried in a furnace 5 having its sides lined with asbestos, fire-brick or like plates 6<a>, and provided with an aperture 5e for its nozzle 8<a> and a removable plate 9 opposite thereto for withdrawal of the pot. The plunger 13 has a head 13b to engage a slot 12a in a slide 12 which is forced down, against the action of a spring 20, Fig. 1, by link-work 18, 24 and a hand-lever 28. The upward movement of the slide is limited by a set-screw 29 unless it is desired to withdraw the plunger 13 for replacement &c. One half 58<a> of the mould is carried by an angle member 55 secured to a dovetail slide 50 movable on a table 30 which is capable of transverse, longitudinal, and vertical adjustment by screws 36, Fig. 4, and 34, and 32, Fig. 3, respectively, and also of a swinging movement about the axis of the vertical screw for convenience of adjustment &c. of the mould and parts associated therewith. The other mould half 58b is mounted on a hollow segmental cylinder 53 moved axially in a block 51, secured on the dovetail slide 50 by a hand-oscillated eccentric 46 adjustably connected thereto and pivoted on the table 30. An ejector 60d. Fig. 3, is adjustably secured to a secondary cylinder 59 free to slide in the cylinder 58, and is moved relative thereto by a cross-pin 63 secured in the block 51 and adapted to engage screw stops 60<a>, 61. When the eccentric withdraws the cylinder 53, after a cast has been made, the dovetail slide 50 is also withdrawn by a spring 71 so that the mould is moved bodily from the nozzle 8<a> until the slide is arrested by an adjustable stop 73a. Continued movement of the eccentric then separates the mould halves, and finally, when the stop 60<a> of the cylinder 59 strikes the pin 63, the ejector is arrested and forces out the casting. The cylinder 53 has a flange 54, Fig. 2, with holes in which slide guide-rods 56, 57 carried by the block 51 and member 55. The eccentric is carried by bearings 41 adjustable by screw 14<a>, 14<b> on the table 30 and connected by nuts and stays 66, 67 to the furnace casing 5. In its lateral movement the table 30 slides on a plate 37 connected to the vertical screw 32, and the nut 33 engaged by the screw slides, when moved by the longitudinal screw 34, on rods 3, 4, carried by legs 1, 2 on which are also mounted the furnace, an auxiliary heater at 78 for the nozzle, and adjustable screw supports 31<a> for the end of the table 30.

Title: Improvements in cupborad door catch
IPC: E05C19/02
Filed: 1947-09-18
Abstract: 644,435. Catches. COMEY, C. S., and SAXTON, M. F. Sept. 18, 1947, No. 25487. Convention date, Sept. 19, 1946. [Class 44] A friction catch for cupboard and like doors has a dual pivot with associated springs of differing'strengths so that rotation about one pivot during closing requires less force than that required for rotation about the other pivot on opening the door. A swinging catch 36, Fig. 1, of box shape and bent from a single piece of metal, is pivoted on a pin 34 which is fixed near the upper end of a U-shaped yoke 28. The ends of a helical spring 40 mounted on the pin 34 react against the yoke and catch to urge the latter outwardly, the catch having a stop tongue 38, Fig. 7, formed at its lower end which cooperates with a pin 30 on the yoke. A one-piece sheet metal frame 10 housing the catch and secured to the door by screws passing through flanges 12 formed thereon has its top and bottom face plates 18 perforated at 20 to receive the pin 30, and its end face 14 provided with a latch aperture 16. The yoke 28 is normally maintained in its position, as in Fig 1. by a relatively strong compression spring 42 of arc form which abuts against lugs 32 and 26 formed on the yoke 28 and back plate 24 of the frame 10 respectively, or in a modification, Fig. 9, the lug 26 may be integral with the back plate 24<1>. On closing the door the strike surface 52, of a keeper member 44 secured to the jamb by corner prongs 50 and a single screw, contacts the cam face 46 of the catch 36, pivoting the latter about the pin 34 against the light resistance of spring 40, until the catch finally springs behind the keeper to retain the door closed. On pulling the door to open it, the yoke is forced to pivot about pin 30 against the action of the strong spring 42, as in Fig. 7, since the cam surface 48 is substantially radial to pin 34.

Title: Improvements in or relating to electromagnetic wave transmission systems
IPC: H01P1/163
Filed: 1958-08-08
Abstract: 883,179. Multiplex radio signalling. WESTERN ELECTRIC CO. Inc. Aug. 8, 1958 [Aug. 20, 1957], No. 25501/58. Class 40(5). [Also in Group XL(b)] A system for the transmission over long distances of TE 01  circular mode electric wave energy over a broad band of operating frequencies comprises, Fig. 1, a terminal station 11, which may be a transmitter or a repeater, connected to a receiver or repeater station 12. Transducers 13 and 14 for conversion into and from TE 01  wave energy are interposed between the stations 11 and 12 and the long distance transmission line 15 which is connected to the transducers by sections of waveguide 20 and 22 and tapered conical sections 19 and 21. Connecting station 11 and transducer 13 are three channels 11a, 11b and 11c carrying three different frequency channels f 1 , f 2  and f 3  which are multiplexed in transducer 13, and connecting transducer 14 and station 12 are three transmission paths 12a, 12b and 12c carrying the again separated frequency channels f 1 , f 2  and f 3  in dominant mode guides. Fig. 2 shows a mode multiplex system in which a plurality of dominant mode TE 10  modulated signals of different frequencies are transformed into TE 01  circular electric waves at corresponding frequencies. Thus, a first modulated TE 10  wave signal f 1  entering guide 10 is transformed into a first modulated TE 01  circular electric wave at the same frequency in circular cylindrical guide 4. The signal passes to long guide 1 through circular cylindrical guides 3 and 2 and tapered conical sections 7, 6 and 5, and similarly for signals f 2  and f 3  entering guides 9 and 8. The tapered conical sections each have a cone angle which is a minimum adjacent the larger diameter waveguide, increases to a maximum at a location between the waveguides and decreases towards the waveguide of smaller diameter, such that the TE 01  circular mode electric wave energy propagates through each conical section with little mode conversion. Each tapered section can comprise a plurality of portions each having a different constant cone angle for the controlled generation of a single higher order circular electric mode, or a section of gradually changing cone angle for the controlled generation of a plurality of higher order circular electric modes, the cone angle being zero at both ends of the section, or a section of gradually changing cone angle, which is finite at both ends of the section. Formulae for the form of the tapered sections are stated. In one example the cone angle follows a "raised cosine" law along the taper, i.e. follows a function of the type (1- cos #) or its trigonometric equivalent. Specification 719,258 is referred to.

A hook-device, e.g. for suspending a ceiling- panel 1, Fig. 1, from a joist 2 or other support, comprises a base 3 fixed to the panel and formed with a bifurcated-end 5 in which hook-member 7 is pivoted and urged by gravity to the releaseposition shown in broken-lines. Member 7 is cocked in the position shown in full-lines on the left of Fig. 1, by one or more springs 14 anchored to a pin 15 and carrying a pin 13 located in a notch 12. The panel and hook-device are moved past the joist, which causes the hook-member to pivot clockwise and extend springs 14. Once past the joist, the springs restore the hookmember, which engages the joist as the panel is lowered to the position shown on the right of Fig. 1, the pin 13 being ejected from the notch. The panel may be removed by raising it until the hook-member hangs vertically and can pass the joist as the panel is lowered. A check-spring 16 acts against springs 14. In a modification, hookmember 25, Fig. 4, is pivoted at 24 to base 20 and is cocked by spring 29 engaging a baseprojection 27. When the member engages the support, it pivots anticlockwise to eject the spring from projection 27 and engages a shoulder 26.

Abstract: 814,732. Ironing. FOSTER & CO. Ltd., R. S. Sept. 7, 1955 [Sept. 20, 1954; July 13, 1955], No. 25679/55. Class 138 (2). A device for use in pressing pleats in skirts comprises a horizontally disposed supporting arm 7 (Figs. 1, 2), means for securing the arm 7 to the table 2, bench or pedestal of a steam pressing machine, and an elongated and horizontally disposed member 9 with which a skirt 19 can be engaged so that the member 9 defines a line along which a pleat is to be pressed, the member 9 being hinged about a horizontal axis to the arm 7 so that when the arm 7 is secured to the table 2 the member 9 can be swung downwardly into and upwardly out of the space existing between the pads 1, 3 of the machine when the top pad 3 is raised. In one example, Figs. 1, 2, the elongated member 9 comprises a blade e.g. of thin strip metal which may be perforated and is secured within a slot formed in the upper edge of an elongated board 10 of plywood pivotally secured within a clip 11 on a pivot pin 12. A wing nut 15 and bolt 13 passing through an arcuate slot 14 in the board 10 hold the board 10 and blade 9 in adjusted position. The clip 11 is fixed to a tube 16 which acts as a hinge pin for the clip 11 by being rotatably mounted within the arm 7 which has a downwardly bent portion 7a slidably and rotatably mounted in a socket tube 6. The arm 7 is held in adjusted position by means of a thumb screw 8 in the tube 6 which is secured to a clamp 4. Fig. 2 shows the blade 9, in full lines, in position to receive a skirt for pressing and, in dotted lines, in the horizontal pressing position. In a second example, Fig. 7, the elongated member comprises a length of wire 26 extending between the arms 27a, 27b of a U-shaped tubular metal frame having a base portion 27 and a reinforcing member 28. The frame is rockably mounted on a U-shaped clip 36 by means of a pivot pin 37 passing through the member 28, the frame being held in its adjusted position by means of a bolt and wing nut 39. The clip 36 is secured to a tube 40 mounted for limited rotation in a tubular arm 24 having a downwardly bent portion 24a engaged over a spigot 23 secured to a clamp 21. One end of the wire 26 is removably engaged over a hook bolt 29 having a wing nut 30 for adjusting the tension in the wire 26. A length of closely wound coiled wire spring (Fig. 8, not shown) extends parallel with and close to one side of the tubular member 28 and is used to hold the skirt in place. One end of this spring is anchored to a pin projecting from the arm 27a, while the other end is fitted with a hook detachably engaged over a pin projecting from the arm 27b. In a modification (Fig. 13, not shown) the spigot 23 is slidably mounted on the clamp 21 instead of being fixedly secured thereto.
