Title: Improvements in and relating to supercharging arrangements for aircraft motors
IPC: F02D9/00
Filed: 1935-06-05
Abstract: 436,785. Pumps. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. June 5, 1935, No. 16364. Convention date, June 8, 1934. [Classes 7 (ii) and 7 (vi)] In a charging arrangement for an aircraft engine, in which the action of a blower 5 is occasionally supplemented by an auxiliary blower 7, a flap valve 10, operated according to the difference in pressure in the suction and delivery pipes 4, 9 of the two blowers, causes the blower 5 to draw air through the carburetter 6 direct from atmosphere when the blower 7 is not effectively working. A piston 13 actuating the valve 10 is moved by fluid pressure-e.g. that of the engine lubricant-which is admitted through a port 15 and exhausted through ports 16, 17 under the action of a piston valve 14, the position of which is controlled by the pressures, referred to above, acting through pipes 28, 29 on plungers 18, 19. When the engine is running at high speed, the high pressure developed by the blower 2 operates, through a pipe 30 and a chamber 27, a capsule 24 to move a sleeve valve 20 to the right, thus preventing fluid from actuating the piston 13 ; in a modification this pressure acts directly on a spring-loaded piston, mounted on the sleeve valve 20.

Title: Process for the production of weakly acidic cation exchange resins
Inventor: WOLF FRIEDRICH
IPC: C08F8/44
Filed: 1961-05-05
Abstract: Weakly acidic cation exchange resins are made by treating a cross-linked carboxyl group-containing condensation resin or salt thereof with a solution of an olefinically unsaturated polymerizable carboxyl group-containing compound and/or a salt and/or a readily saponifiable derivative thereof, which is then polymerized within the condensation resin and, where a readily saponifiable derivative of the above-mentioned type has been used, the product is subjected to post-polymerization saponification. Unsaturated carboxylic acids specified are acrylic, methacrylic, crotonic, vinyl acetic, 3-pentene-1-carboxylic, styrene carboxylic and 3-butene-1,2-dicarboxylic acids.  The polymerization of the unsaturated acid may be initiated by hydrogen peroxide, potassium persulphate, sodium sulphite or a redox catalyst.  The examples describe the polymerization of: (1) aqueous methacrylic acid in the sodium salt of a condensation product of resorcylic acid and formaldehyde; (2) aqueous sodium acrylate in the sodium salt of a condensation product of resorcinol, phenol and formaldehyde which has been treated with monochloroacetic acid; and (3) aqueous methanolic acrylonitrile in the sodium salt of a condensation product of phenoxy-acetic acid and formaldehyde, followed by acid or alkaline hydrolysis of the polyacrylonitrile.

Magazine gramophones.-In a device for transferring or conveying a disc record, means are provided to grip the record by engagement with the edge of the central aperture and with a point on the outer edge of the record. As shown, a construction capable of dealing with records of various sizes comprises an arm 11, Fig. 1, fixed to a post 2 capable of sliding and rotating in a sleeve 3, and having at its free end a pin 4 and at its other end a plate 6. The latter is slidable in a slot 8 in the arm 1, and has a bevelled and curved edge 12 and a pin 9 connected by a tension spring 10 to the free end 11 of the arm 1. A rotatable spindle 13 within the post 2 has a crank 14 to which is attached a link 17, and the latter has a slot in which the pin 9 can slide. To pick up a record, the spindle 13 is revolved so that the link 17 moves the plate 6 to the left, Fig. 1. The arm 1 is now moved so that the pin 4 passes into the central aperture of a record, and further movement of the link 17 releases the pin 9 so that the plate 6 under the action of the spring 10 moves, and the edge 12 thereof engages the perimeter of the record. The latter thus moves slightly so that the edge of its central aperture engages the shoulder 5, and the record can then be lifted. In a modification capable of lifting records of two different sizes, such as 10-inch and 12-inch records, the arm 18, Fig. 5, has a flange 19 and at its free end a shouldered pin 21. A stop 25 projecting just below the flanges 19 is fixed mid-way along the arm 18. Two plates 26, 31, Fig. 8, are connected by pillars 27, 28, which are slidable in slots 29 in the arm 18.

The rate of flow of gas through a coiled tube 1 is regulated by varying the temperature of the tube electrically. The flow-rate is measured by an ionization aninometer or other transducer 3 which feeds a signal to an amplifier 2 where it is compared with a reference signal to effect changes in the current supplied to the coil in accordance with changes in the flow-rate from a predetermined value. In Fig. 2 (not shown) a pair of coils are connected in parallel, one coil feeding the load and the other being open to exhaust, selective variation of the coil temperatures being used to vary the rate of flow of gas to the load. Fig. 3 (not shown) illustrates a similar series-parallel arrangement, and in Fig. 4 (not shown) a parallel arrangement is used to proportion gas flow through four separate paths. In Fig. 5 (not shown) series connected coils (R1, R2) have a centre fluid tapping fed to the load, and each is fed with current through an oppositely conducting diode and an amplifier capable of producing a positive or negative output to selectively heat the coils. The Specification sets out temperatures, currents and dimensions, and states that the coils may be of platinum, nichrome or stainless steel. The tubes may be packed with particles.
