Title: Improvements in the purification of oxo synthesis products
IPC: C07C27/22
Filed: 1955-09-14
Abstract: Oxygen-containing organic compounds, obtained by the reaction of olefines with carbon monoxide and hydrogen in the presence of aqueous cobalt salt solutions at raised temperature and pressure, are purified by subjecting the crude primary product coming from the oxo stage, without cooling, to a partial pressure release and keeping it under pressure without separating the water and, if the temperature of the oxo stage is below 150 DEG  C., with additional spraying in of hot compressed water or superheated steam. Preferably the process is carried out at a temperature between 150 DEG  and 180 DEG  C. and may be carried out continuously or otherwise.  The preferred decobalting pressure is between 3 and 40 atm.  The preferred conditions for the oxo process are a temperature of 130-200 DEG  C., a pressure above 100 atm., and 0.01 to 0.2 per cent by weight of cobalt, as a cobalt salt solution, based on the weight of olefine.  In the examples (a) a C8-polymeric olefine is treated with carbon monoxide and hydrogen at 180 DEG  C. and 300 atm. in the presence of cobalt acetate; the product is passed into a decobalting vessel where its pressure is reduced to 15 atm. at 165 DEG  C.; the suspended cobalt and cobalt oxide is separated, if necessary, and an organic phase consisting of crude aldehyde, free from cobalt, is obtained; (b) a crude product obtained by carrying out the oxo process on camphene in the presence of aqueous cobalt acetate solution is treated as in (a); (c) the process of (a) is carried out except that steam at 18 atm. is introduced into the decobalting vessel in such an amount that the temperature is kept at 175 DEG  C.; and (d) the pressure on crude butyraldehyde mixture obtained by carrying out the oxo process on propylene is reduced to 15 atmospheres, the heat entrained with the product keeping the decobalting vessel at 180 DEG  C.; a product entirely free from cobalt is obtained.

Abstract: 455,731. Shock absorbers. FEINMASCHINENBAUGES., 6, Charlottenstrasse, Berlin. Sept. 26, 1935, No. 26675. Convention date, Oct. 16, 1934. [Class 108 (iii)] In shock-absorbers for aircraft and motor vehicles comprising two pistons movable relatively to one another against the action of liquid damping means, one of the pistons is formed as a floating piston which separates the damping liquid from a resilient part of the device and which acts to vary the effective piston surface in accordance with the degree of shock. As shown in the Figure, the floating piston 7 is slidable on the working piston 2 and separates compressed air in the upper part of the enclosing cylinder 1 from the damping liquid in the annular space between the piston 1 and a disc 5 fixed at the lower end of the piston 2. The disc contains one or more tapered ports 9 or valves. In operation, on compression of the device, the compressed air passing through holes in a second disc 4 at the upper end of the piston 2 forces the piston 7 to eject liquid through the damping ports 9. In a modification the compressed air is replaced by helical springs, rubber buffers, &c., and in a second modification, the floating piston slides inside the working piston which contains the damping liquid.

Title: Improvements in or relating to the tuning of radio circuits
IPC: H03J7/04
Filed: 1934-09-20
Abstract: 443,505. Valve circuits for wireless reception. COLE, Ltd., E. K., Priory Crescent, Southend-on-Sea, MARTIN, A. W., 1, Thames Close, Leigh-on-Sea, and INSKIP, F. A., Trelawney, Carlingford Drive, Westcliff-on- Sea. Sept. 20, 1934, No. 26993. [Class 40 (v)] A radio receiver is automatically brought into exact tune with a desired signal by means including a valve, the impedance of which varies with departure from exact tune, and which acts to vary the frequency of the local oscillator in a compensatory sense. Fig. 1 shows part of a superheterodyne receiver including a frequency changing octode VI, intermediate frequency amplifier V2, and signal diode D1, from which a lead 8 passes to the subsequent low frequency stages. Automatic volume control potentials derived from diode D2 are applied firstly to V2 and secondly to the control grid of V1 from the common point of resistances 4, 5 in the cathode lead of V2 ; The intermediate frequency output of V2 is applied over transformer 6 and condenser 10 to tuned circuit 14, 15, which is connected to a pair of oppositely arranged diodes D3, D4, alternatively included in the circuit by a switch S1, S2. The moving contact S of the switch is frictionally mounted on the shaft of the tuning control of the receiver so that in one direction of rotation S1 is closed and in the other S2. The load resistance of the diodes is included in the grid biassing circuit of a valve V3 the arrangement being such that with D4 operative the grid potential of V3 becomes increasingly positive, and its impedance falls correspondingly, as the tuning approaches resonance with the desired signal. Valve V3 in series with condenser 20, is shunted across the tuning condenser 22 of the local oscillator, the frequency of which is thus automatically varied by varying the impedance of V3. With the switch on contact S1 the grid potential becomes increasingly negative to control the oscillator frequency in the reverse sense. Thus the receiver is brought into exact tune from a position either above or below the desired frequency, since the maximum voltage across D3 or D4 is fixed by A.V.C. on V2.

Class 61 A clamp comprises a slide 1 having at one of its ends an arm 2 which acts as an abutment or anvil for a plunger 4, 5, which is moxable axially in an arm 3 slidable along the slide 1, there being a lever 7 between the stem 4 of the plunger and a damping lever 10, means for locking the lever and thereby the stem against movement, and a device which renders the locking means ineffective. The lever 10 shown is pivoted at 11 between two plates 12a integral with arm 3, and extends at an acute angle, 30 degrees for example, to the plane through the parts 1, 2, 3. The lever 10 carries a pin 8 for the lever 7 and a pin 18 for a hand lever 17. The latter is normally urged by a spring 19 to bring a pawl 20 thereon into engagement with teeth 22a on the plate 12a, the arrangement being such that when lever 10 is moved clockwise for damping purposes the pawl and teeth lock the parts against movement in the reverse direction. Unlocking is effected by applying pressure to the lever 17. The plate 5 of the plunger is mounted to move with respect to the stem 4 against the action of a spring 27 through a distance greater than that moved by the stem when the pawl moves. In a modification, Fig. 2 (not shown) a pin extending from the sides of a slot in lever 17 engages in tapering holes in the side plates of the lever 10. A spring acting on lever 17 urges the pin into locking engagement with the curved surface of the plates 12a.
