In the second mode suction is maintained until a blockage occurs as signified by the actuation of switch 13 when the motor is switched off and the timing device 17 is triggered. If the blockage clears itself within a preset time suction is recommenced. If the blockage is sustained for such a time the pump is reversed for a preset period to clear the blockage.

Abstract: 1,242,731. Bulk negative reistance device. JAPAN, AGENCY OF INDUSTRIAL SCIENCE & TECHNOLOGY MINISTRY OF INTERNATIONAL TRADE & INDUSTRY. 22 Aug., 1968 [22 Aug., 1967; 27 Nov., 1967 (4); 29 Nov., 1967; 26 Dec., 1967; 8 March, 1968 (5); 21 March, 1968; 23 April, 1968; 5 July, 1968], No. 40199/68. Heading H1K. A bulk negative-resistance device consists of a two valley semi-conductor with ohmic electrodes adjacent its ends and a layer of high dielectric constant insulation disposed on the body between the ohmic electrodes. This serves to prevent the formation of high field domains in the body. Typically the body is of gallium arsenide and the insulation barium titanate. The body may be flat with insulation formed on or inset in one or both faces, a rod surrounded by a sleeve of insulation or a Y- or H-shaped member of circular or laminar cross-section with an ohmic contact at the end of each arm. Preferably the insulation extends into contact with the ohmic contacts and in this case to prevent the output being shunted through it the insulation may be divided by one or more lateral slots. Instead of extending the insulation in the above manner the cross-section of the ends of the body adjacent the cathode or both ohmic contacts may be increased by a gradual or stepwise increase in thickness or width of the body there. In all cases a fixed D.C. bias is applied between the terminal ohmic contacts and the input signal fed to one contact and output taken from the other. Alternatively capacitive or waveguide input and output arrangements are provided adjacent these contacts. For higher power a parallel-connected stack of devices with common electrodes is used. One or more control electrodes may be disposed on each discrete area of insulation in any of the above configurations. A device adapted for insertion between the conductors of a strip transmission line is also described. In this case, with the device acting as an amplifier the amplification is determined by the length of the body and electron density. To achieve higher amplification factors for a given applied voltage a plurality of devices may be mounted in series along the strip line, mutually spaced by layers of insulation. The ends of the body are preferably tapered to reduce reflections at the semiconductor air interfaces.

Abstract: 1,106,823. Air cushion vehicles. BRITISH HOVERCRAFT CORPORATION Ltd. 9 Sept., 1966 [22 Sept., 1965], No. 40467/65. Heading B7K. An air cushion vehicle has a skirt formed by a corrugated skin of flexible material having ridges projecting on one side thereof and a flexible web extending from the peak of each ridge to an attachment point on the vehicle body to restrain the skin from spreading when the pressure of air on said one side is higher than on the other. The skin I may be corrugated vertically (Figs. 4 and 5, not shown) or horizontally. In Fig. 2, a cushion-containing peripheral skirt comprises adjoining corrugations which form ridges 2 to each of which is secured a web 8 formed with parabolic-profile cut-outs reinforced at 8B and secured at 8A along a line 5 on body structure 3, the cut-outs being arranged so that the tips of one web pass through the out-outs of an adjoining web. A similar construction is utilized in an inflatable cushion-dividing skirt (Fig. 6, not shown), comprising opposed corrugated walls each stabilized by webs such as shown in Fig. 2, the tips of the webs from one wall crossing and passing through cut-outs in the web from the opposite wall. The webs may be continuous sheets apertured for the passage of cushion air. The webs may extend only part-way from the skirt ridges, being attached to the body by flexible ties. Reference has been directed by the Comptroller to Specification 1,047,620.

Title: Winding machine
IPC: B65H54/38
Filed: 1973-08-29
Abstract: 1436736 Preventing ribbon winding W REINERS VERWALTUNGS-GmbH 29 Aug 1973 [1 Sept 1972] 40589/73 Heading D1J To prevent ribbon winding the friction contact between a package 1 and a thread guide drum 2 is intermittently varied, there being an additional drum 31 serving to press the package 1 against the thread guide drum 2. The drive to the thread guide drum 2 is also varied. In the drawing a rocker shaft 5 operates linkwork 'to cause a friction pulley 4 to move to and from a setting in which it couples a driving pulley 3 with a drum 2. The rocker shaft 5 also oscillates a rod 14 in a manner causing spring means 18, 19 to bias a pivoted lever anti-clockwise about its pivot 17a. Such displacement of the lever 17 is prevented by an arm 20 thereof engaging a pawl 21. As the package 1 increases in diameter it rocks its supporting frame 22, and a toothed segment 23 that is rigid with the frame 22, anti-clockwise in a manner causing a tooth on the segment 23 to rock the pawl 21 out of engagement with the arm 20. The oscillation of the rod 14 by the rocker shaft 5 is now free to cause the lever 17 to repeatedly cause a detent 25 on the lever 17 to press against a toothed segment 26 that is rigid with the frame 22. Each thrust of the detent 25 against the toothed segment 26 serves to temporarily reduce the pressure of the package 1 against the thread guide drum 2. The drum 31 ensures that the contact pressure between the package 1 and the thread guide drum 2 does not fall below a predetermined minimum value. As the package 1 increases in diameter the spring 32 is elongated to increase the thrust of the drum 31 on the package 1. Alternatively the spring 32 may be absent so that the drum 31 exerts a constant thrust on the package.

Title: Process for obtaining thermoplastic polycarbonate from a solution thereof

Filed: 1963-10-16
Abstract: Polycarbonates are recovered from their solutions either in halogenated aromatic hydrocarbons with a b.p. of 130-200 DEG  C. or in anisole by feeding the solution into a heated extruder operating under normal or reduced pressures and in which the solvent is continuously evaporated at gradually increasing temperatures, withdrawing solvent vapours through one or more outlets located at intermediate points in the extruder and extruding molten polycarbonate from the far end of the extruder. The polycarbonate may be initially dissolved in a mixture of one of the above solvents and a lower boiling point solvent and the latter may first be removed in a film evaporator.  The extruder may be of the single-screw or twin-screw type each having two outlets through the first of which the bulk of the solvent distils off under atmospheric pressure and through the second of which residual solvent is removed under vacuum. The worm of the single-screw extruder may have two short sections of increased diameter (respectively between the two solvent outlets and the second outlet and the extrusion nozzle) which form obstructions. The worms of the twin-screw may each have a single such obstruction between the two solvent outlets. Examples describe the recovering of the polycarbonate of bisphenol A from its solution in a mixture of methylene chloride and chlorobenzene or o-chlorotoluene.
