Title: Method of pleating and apparatus for the practice of such method
IPC: D06J1/06
Filed: 1958-06-19
Abstract: <PICT:0857405/IV (c)/1> <PICT:0857405/IV (c)/2> <PICT:0857405/IV (c)/3> Cloth is pleated by a process comprising saturating the cloth with water heated to a temperature below its boiling point so that the cloth becomes limp with moisture and is brought to the temperature of the water, applying moistureabsorbent sheet material, e.g. paper, to the surfaces of the cloth, immediately thereafter forming pleats in the cloth and in the moisture -absorbent sheet material while the cloth is hot and moist, and setting the pleats in the cloth at a temperature of at least 350 DEG F. whereby, on completion of the setting operation, the pleated cloth is substantially dry.  Fig. 1 shows a plan view of a suitable pleating machine for carrying out the process and Fig. 2 is a sectional side view on the line 2-2 in Fig. 1.  The cloth to be pleated is passed from the roll 20 between rollers 25, 12 freely rotatably mounted in the tank 23 containing water 24, preferably heated to 200 DEG -205 DEG F., and then between rollers 26, 27 where excess water is removed, the beater roller 18 rotated by a motor 17 and having a plurality of blades 19, which contact the cloth in rapid succession, also serving to remove a certain amount of excess water by shaking. Rollers 28, 29 carry rolls of moisture-absorbent sheet material 40, 41 which are fed over rollers 30, 31 to the point 39, at which they contact the wet cloth, and the reciprocating knives or blades 32, 33 pleat the assembled sheets.  The pleated assembly is then passed directly between heated rollers 34, 35, preferably heated by circulating steam or hot air through pipes 42, 47, 471 or electrically, to dry and fix the pleats in the cloth, and then rolled into a roll 37 on a roller 43 driven by a motor 36 to move the cloth progressively through the machine.  In a modified machine shown in Fig. 3, heaters 48 are provided in association with the tank 23 and a further sheet of paper having the functional characteristics of a pebble crepe material is fed from a roll 50 into contact with the cloth between the cloth and the sheet fed from the roll 41.  This modified machine is preferably used in pleating velvet type material, paper such as Kraft tissue being supplied by the rolls 40, 41 while a pebble crepe paper is supplied by the roll 50 so that the material dries more slowly and no marks are left on the surface of the material.  Specified fibres are nylon, "Dacron" (Registered Trade Mark) and cellulose acetates, which may be in combination with other yarns and in the form of taffetas, jerseys, crepes, velvets, velveteens and prints. In pleating cellulose acetate cloth the water may contain ammonia.

Title: Improvements in engines with pistons which both reciprocate and rotate
IPC: F01B3/00
Filed: 1930-06-28
Abstract: 358,046. Engines. MAARSEVEEN, A. C. VAN, 25, Anna van Buerenstraat, The Hague. June 28, 1930, No. 19725. [Class 122 (iii).] In a multicylinder steam or internal-combustion engine, the pistons are connected to a cam consisting of a pair of helical grooves of different radii at the points of reversal. A piston 4 working in a cylinder 2 consists of a central portion 4 on which is mounted an external part 5 provided with a ball bearing 6. Each piston-rod carries a cam 9 on the surface of which are two intersecting grooves 10 into which rotatable pins project. The motion is transmitted to a driving-shaft 21 through drums 22 mounted on the piston-rods, the drums having pins 23 which co-operate with axial grooves in a cylinder 25 fixed to the engine shaft. The drums 22 can be uncoupled by a clutch during the working of the engine to facilitate repairs or starting. The rotational speed of the piston-rod 8 may be varied by rotating the pins which engage the cam grooves ; the pins are mounted on a ring 15 carrying a toothed wheel 17 which is driven from a shaft 19 through gearing 20, 18. The shaft 19 is driven from the engine shaft 21 through a change-speed and reversing gear.

Title: Improvements in or relating to direct reading radio goniometers and measuring apparatus for alternating electrical waves
IPC: G01S1/02
Filed: 1939-07-06
Abstract: 530,935. Directive wireless systems. SOC. FRANCAISE RADIOELECTRIQUE. July 6, 1939, No. 19734. Convention date, July 6, 1938. [Class 40 (v)] [Also in Group XXXVI] Changes in the amplitude of an alternating current are-first transformed by co-operation with a local oscillator into corresponding phase-variations, the transformed currents then being fed, together with the local oscillations, to a control circuit which provides a zero output voltage when the two are in phase-quadrature and indicates any subsequent change in phase as a change in frequency. As applied to a direction-finding system of the kind described in Specification 470,060, signals from a pair of crossed frames (or Adcock aerials) are applied to a receiver I at the terminals 1, 1<SP>1</SP> and 2, 21, together with signals from a " sense aerial at the terminal A. A local oscillator II applies a switching or reversing frequency to the terminals 3, 3<SP>1</SP> so that the phase-difference between the output taken from the terminals 4, 41 and the local switching current depends, in known manner, upon the orientation of the distant transmitting station. The output current is applied by a transformer 6 to a frequency-discriminating circuit III of the kind used for automatic tuning control, the switching frequency being fed to the same circuit at the points 10, 101 through a delay network IV so as to give a phase-displacement which varies with frequency. The amplitude of the output from the terminals 11, 111, which depends upon any departure from phase-quadrature between the two applied currents, is fed back to adjust the frequency of the oscillator II until the normal " quadrature " balance is restored. The resulting change in the frequency of the oscillator then indicates the bearing of the received signal. In a modified arrangement, the frequency of the oscillator II is kept fixed, and the frequency of a second oscillator is similarly controlled by the received signals, and serves as an indicator.

Filed: 1958-06-26
Abstract: 869,516. Gas-blast switches. I-T-E CIRCUIT BREAKER CO. June 26, 1958 [Dec. 16, 1957], No. 20565/58. Class 38 (5). [Also in Group XXXVI] A recirculating gas-blast switch has insulating bushings 12, 13 passing through opposite ends of an elongated tank 11, a stud 14 extending through the bushing 12 and carrying a fixed contact 16, and a conducting tube 15 extending through the bushing 13 and housing an axially movable contact assembly 20 which is electrically connected to the tube 15 by a stationary bridging contact assembly 25. The assembly 20 includes main and arcing contacts formed by concentric tubes 42, 43 which are slit at their ends to provide segments which are biased by springs. The contact tubes are secured to a tube 29 which extends from a differential piston assembly 30. The tank 11 is connected to a high-pressure source of gas so that the contacts are always surrounded by high-pressure gas. When the contacts are closed the gas acts through the tube 29 and through a bore in the piston assembly 30, so that pressure gas from the tank 11 acts on the left face of the larger piston 34 as well as on the right face of the smaller piston 33, the space between the pistons being connected to a low-pressure reservoir. To open the contacts, the cylinder 72 housing the larger piston 34 is vented through a spring biased valve 83, a pipe 78 and a blast valve (not shown) to the low-pressure reservoir so that the pressure gas in the tank 11 acting on the smaller piston 33 opens the contacts, a blast of gas flowing through the movable contacts, the tube 29 and the piston assembly 30 to the low-pressure reservoir until the piston 34 closes the valve 83. The contacts are closed by closing the blast valve and opening a further valve which connects the pipe 78 to the high-pressure source so that high-pressure gas acts on the larger piston 34 and closes the contacts. Fig. 8 (not shown) illustrates the external valve gear and equipment for a multi-pole or multi-break assembly.
