IPC: D06J1/00
Filed: 1916-11-25
Abstract: 110,052. BerthÚlemy, C. Nov. 25, 1916. Ironing-machines with handoperated fiat-irons; combimed with pleating-machines.-A heated boxiron 1 can be moved over a sheet of material while this is pleated under the iron by a serrated plate 6 operated by links 7 from a, disk 15. The degree of eccentricity of the pivot pin 10 for the links can be adjusted by means of a groove in the disk which is geared to the wheels 23 carrying the iron. A counter-plate 26, hinged by rods 27 to the sides of the iron at 28, is used to hold the fabric so as not to be affected bv the return movement of the plate 6. The plate 6 having been held down to the work by a spring 11 engaging under a series of lugs at different heights on the sides of the iron, a forward movement of the apparatus causes a series of pleats to be fed under the iron and fixed by the hot pressure. The weight of the iron is borne centrally by the shaft 22 of the carrying-wheels by means of a screw 25 threaded into the iron and engaging the middle of the shaft. As an alternative method of use the ends of the shaft may be held by sliding rods 33 in bearings in a frame 31 so that the carrying wheels are idle. In this case the work is placed on an endless apron 36 which is driven by a handle geared to the disk 15.

Title: Improvements in or relating to spring suspension systems and shock absorbers
IPC: B64C25/64
Filed: 1929-06-04
Abstract: 333,969. Austing, L. r. June 4, 1929. Springs, arrangement of.-In spring-suspension systems applicable to the landing gear of aircraft and to other vehicles in which springs are substantially enclosed in the wheel, movements of the wheel relatively to the frame brings about relative movement of levers pivoted to the wheel axis, such movements of the levers being adapted to actuate rubber or pneumatic springs and fluidfriction vibration-dampers. In the construction shown in Figs. 4 and 5, the apparatus is substantially enclosed between a dished disc 5 and a dished wheel 2, carried at the end of an arm 25 pivoted to the landing carriage of an aeroplane, while the two levers 19, 20 pivoted to the axle 1 of the wheel are also connected by links 21, 22 to the landing gear. Vertical movement of the wheel with its axle 1 thus causes relative angular movement of the levers 19, 20, which are connected respectively to a lever 3 fast on the rotatable bush 4 and the disc 5 carrying an abutment 6. When the angle between the levers 19, 20 increases, the angle between the lever 3 and abutment 6 decreases and the rubber blocks 7 are thereby compressed. These blocks are separated by radial plates 8 the inner ends of which are guided by transverse pins 9 engaging channel stem having inwardly projecting flanges 11. The plates are provided with projections 12 which engage holes in the rubber blocks. Movement of the lever 3 also operates through the linkwork shown a. radial vane 16 movable in a casing secured to the disc 5 and containing liquid, the damping effect depending upon the flow of liquid from one side of the vane to the other. In the modification shown in Figs. 6 and 8, the rubber spring is replaced by a pneumatic compression element. The casing 33 is secured to the arms 25, 26 and is formed internally with two liquid compression chambers 49, 50 in which move vanes 37, 44 each provided with packing 38, 45. The vanes rotate about the axle 1 and are integral with an arm carrying an operating-pin 19 which passes through a slot 52 in the cover and is connected by a link 21 to the landing carriage. When the vanes moves in an anti-clockwise direction, liquid from the chamber 49 is forced through the passage 46 into the chamber 50 and also passes through the passage 41 into the chamber 47 bounded at its upper end by the radial partition 39. Air is thus compressed in the chamber 47 and resists rotation of the vanes and vertical movement of the wheel relatively to the landing carriage. When the vanes move in a clockwise direction, liquid passes from the air chamber 47 into the chamber 49 through the one-way valve 42. The rate of movement is, however, limited by the restricted flow of liquid from the chamber 50 through the passage 46.

Title: Improvements in and relating to bandages, dressings and the like
Inventor: HEMSTED EDWARD CHARLES EDMUND
IPC: A61F13/00
Filed: 1954-06-17
Abstract: A dressing is formed with the part which is to contact the body made of a coherent mass of soluble fibres and the remainder made of woven, insoluble fibres.  In the preferred form, a strip of woven alginic acid fibres has short, spaced lengths immersed in a solution of medicament and, after drying, these lengths are treated with ammonia to convert the alginic acid to soluble ammonium alginate.  The strip is then cut into individual dressings, each comprising a soluble section at one end while the remainder is insoluble.  Instead of preparing the dressing by a continuous process a strip may be wound on a rectangular frame or folded backward and forward on itself between clamping plates and then an end portion, forming a short length of each bandage, is dipped in medicament solution and treated with ammonia.  It is also proposed to prepare soluble fibres, which in this case may be cellulose ether, and to attach these to an insoluble backing by adhesive.  In each case the soluble fibres dissolve in body fluids and carry the medicament with them. Specification 765,457 is referred to.

Abstract: 259,656. Berry, J. C. July 13, 1925. Endless-chain machines; cleaning - apparatus; feeding and measuring; strain, preventing. - A brick-making machine of the type described in Specification 5625/02, [Class 87, Moulding &c.], is modified in detail. In the parent construction the main cylinder of the pug-mill 10 delivers to a coaxial chamber 17 of larger diameter the outlet 21 from which is opened and closed alternately by rotating delivery cams 20 on an extension of the pugmill shaft. Two inclined compressor blades 27, 28 are furnished in addition to the usual pug-mill blades to keep the chamber 17 tightly packed. Mechanism actuated from a pin 30 on the wheel 29 of the driving-gear rocks the shaft 38 and so transmits an intermittent reciprocating movement to the mould-pushing member 43. The latter is guided bv the framework and runs on three wheels on a platform 50. In emergency, an eccentric strap 103 included in this mechanism can slip instead of transmitting the drive. The incoming moulds push the filled moulds under a scraper 54 which removes surplus clay before delivering them to rollers on which they can be reciprocated by hand to strike against stops 102 to loosen the clay. The scraper can be pushed up in emergency against the action of a weight 61 to clear the moulds. A sliding bar 68, which reciprocates in front of the scraper to clean it, is actuated by linkage 86, 89 from a rock shaft 83 which is operated intermittently by a piston-and-tube mechanism 71 connected to the previously-mentioned point 30 on the wheel 29.
