Patent GB-971898-A (GB)
Title: Process of preparing unsaturated aliphatic aldehydes
Filed: 1961-02-20
Abstract: a -b -Unsaturated aldehydes are obtained by contacting saturated aliphatic aldehydes with at least one oxide of arsenic, antimony or bismuth at an elevated temperature.  Preferably the a -b -unsaturated aldehyde is separated from the reduced oxide formed, the reduced oxide is oxidised to form a higher oxide and this is then used for the production of further amounts of the unsaturated aldehyde.  The catalyst may be granular or used as a support such as silica or alumina.  The reaction is carried out at 100-600 DEG C. If desired, an inert diluent such as nitrogen may be used to facilitate removal of products from the reaction zone. The process can be made continuous by introducing carefully controlled amounts of air or other oxidising gas into the reaction zone so as to retard the rate at which the solid oxidant becomes reduced. The preferred aldehydes for use as starting materials are those containing 2-4 carbon atoms. In the examples isobutyraldehyde, n-butyraldehyde, and propionaldehyde are converted to methacrolein, crotonaldehyde and acrolein respectively.

Title: Improvements relating to point contact negative resistance devices
IPC: H03F3/12
Filed: 1947-03-05
Abstract: 628,287. Contacting - solid resistances. WESTERN ELECTRIC CO., Inc. March 5, 1947, No. 6241. Convention date, March 2, 1945. [Class 37] [Also in Groups XXXIX and XL (c)] A negative resistance device comprises a body of highly purified silicon in contact with a pointed member, the silicon body being polarized negatively. Highly purified silicon ingots may be produced as described in Specification 590,458, [Group III], and the method of making the negative resistance device comprises the following stages : (a) fuse under non- oxidizing conditions silicon of approximately 99.85 per cent purity with one-third per cent aluminium added (or alternatively, boron may be used) and cut slab or 1 to 2 millimetres thickness ; (b) polish one surface optically flat; (c) heat slab at approximately 1000‹ C. for eight hours; (d) grind unpolished face of slab clear of vitreous material and nickel or rhodium plate this surface; (e) cut slab into small sections and etch in weak hydrofluoric acid to remove about 20 per cent of the vitreous layer; (f) mount in evacuated container with pointed contact element; (g) apply breakdown potential of 250 to 500 volts through series resistance, positive pole being connected to the silicon element; (h) apply stabilizing potential of about 26 volts through a resistance to cause current of 20 m.a. to flow through element in one direction and then in the reverse direction. Fig. 4 shows the silicon element 10 assembled in a ceramic or plastic material cartridge 17 with a tungsten wire contact member 21 bearing against the polished surface of element 10. The contact arrangement between rib 11 and element 10 reduces heat transfer so that element 10 operates at a higher temperature. The addition of the aluminium reduces the losses at high frequencies and ensures the production of a large proportion of P-type material so that the element may function as a negative resistance device. Fig. 8 shows an amplifying circuit comprising an input voltage 43, a negative resistance element 46 of the type shown in Fig. 4 to which a polarizing voltage is supplied by battery 47, and an output load resistor 44. Several other types of amplifying and oscillating circuits are described, and means may also be provided to increase the temperature of the negative resistance element. Fig. 13 shows an arrangement for producing and modulating carrier-wave oscillations, in which carrier oscillations are produced in circuit 102 by means of the negative resistance device 91. Sound waves at mouthpiece 97 effectively vary the pressure and therefore the contact resistance between the tip of contactor 106 and the element, thus modulating the amplitude of the oscillations in circuit 102.
