[Also in Group XIII] In a gas-turbine plant, air is preheated by turbine exhaust gases in a regenerator which surrounds a combustion chamber 1 the gases from which are passed to the turbine. The regenerator (see Group XIII) comprises a number of units, e.g. 10, 20, the flow through which, in cyclic sequence, of heating gas and air to be heated is controlled by cam or hydraulically operated poppet valves. Guide vanes 24 direct heated air towards the combustion chamber 1, some air entering the primary combustion zone of the flame tube 2 whilst the remainder forms an annular, cooling flow about the flame tube and enters the latter towards its downstream end. Hot gases from the flame tube pass to the pipe 3 and thence to the turbine.

Title: Improvements in or relating to a method for improving the strength of artificial insolubilised protein filaments
IPC: D01F4/00
Filed: 1948-04-26
Abstract: The strength of coagulated protein filaments that have been insolubilized with formaldehyde in the presence of an acidified highly-concentrated salt solution, is improved by treating them with an aqueous solution of at least one uranyl salt.  The process may be applied to filaments which have been obtained from alkaline solutions of casein or vegetable globulins, e.g. solutions of peanut or soya bean globulins in dilute caustic soda solution. The hardening may be effected by treatment of the filaments with a concentrated halide salt solution containing formaldehyde, a salt of a reducing sulphur acid, and an acid which does not oxidize the salt of the sulphur acid.  Treatment with the uranyl salt is preferably effected while the filaments are under tension. Aqueous solutions of uranyl acetate, zinc uranyl acetate, or of uranyl salts of hydrochloric, nitric, or sulphuric acid may be used.  Treatment may be effected at raised temperature, e.g. 70 DEG  C.  In an example, a solution of ground nut protein in caustic soda is extruded into a sulphuric acid/sodium sulphate solution and the filaments formed are hardened by soaking them for several hours in a solution comprising brine, formalin, and sulphuric acid.  The filaments are washed and dried, and then treated for 16 hours at 40 DEG  C. with a solution of 3 per cent uranyl acetate in 0.1 N acetic acid.  The filaments are washed and dried. The wet tensile strength is increased by 30 per cent.  In another example, the hardened filaments are stretched to a maximum in a solution of uranyl acetate in dilute acetic acid at 70 DEG  C.  The stretch is maintained for 30 minutes and the filaments are then washed and dried.  The wet tensile strength is increased by 80 per cent. Specifications 513,910, 533,952 and 597,497 are referred to.

Title: Process of demetalling hydroformylation reaction product
Inventor: CARTER CHARLES ELLSWORTH
IPC: C07C45/50
Filed: 1961-03-29
Abstract: A liquid hydroformylation reaction product containing a metal carbonyl is demetalled by passing through a demetalling zone an aqueous medium consisting essentially of water, at a temperature sufficient to decompose the carbonyl, passing through the zone in counter-current 1/10 to 3 volumes of hydroformylation product per volume of aqueous medium in the form of droplets having a diameter of from 0.397 to 12.7 mm. so that the contact time of the droplets with the aqueous medium is at least 1/4 min., and removing the aqueous medium and the liquid product from the zone.  If necessary more than one demetalling zone may be used.  It is preferred to use as starting materials for the hydroformylation process olefines having 4-16 carbon atoms, and an oil-soluble salt of cobalt or iron as catalyst. The hydroformylation process is preferably carried out at 38-316 DEG C. under a pressure of 105-350 Kg./sq.cm. in an elongated coil in indirect heat exchange relationship with an aqueous medium.  When cobalt carbonyl is present the demetalling is carried out at a temperature of at least 121 DEG C.,  The pressure used should be sufficient to maintain the water in the liquid phase.

Title: Improvements in or relating to vibration-absorbing mountings

Filed: 1946-04-15
Abstract: 610,959. Resilient mountings; dashpots. THIRY, L. F. April 15, 1946, No. 11584. [class 108 (iii)] A resilient mounting comprises a tubular housing or outer member 1 coaxially spaced from an inner member 3 by two longitudinallyspaced resilient bushings 6a, 6b to form a substantially closed chamber containing liquid, means for dividing the chamber longitudinally into two compartments 10a, 10b connected by a restricted passage for liquid flow upon relative longitudinal movement between the inner and outer members, control means for varying the effective cross-section area of the passage and a temperature-responsive device for actuating the control means in accordance with temperature variations. In the construction shown in Fig. 3, the chamber dividing means comprises piston ring 9 which can slide axially on the member 3, and radially under non-axial relative movement of the mounting, in a slot formed between spacing members 8. The compartments 10a, 10b are connected by a common bore 13 in the member 3 and respective ports 12, flow through the upper of which is controlled by a valve 15 carried by a bimetallic element 25 secured at its outer end to a knurled adjusting-head 28. The outer end of the valve 15 is centred in the end of a liquid filler plug 21. For large deflections, the characteristic is varied by a cam surface 40, on the member 3, while a limiting buffer 35 of resilient material is provided. A small quantity of gas such as air or nitrogen may be contained in the liquid chamber in order to cushion shocks. The setting of the head 28 is indicated by a pointer relative to a scale on a flange 36 of the member 3. In a modification (Fig. 1, not shown), the valve 15 is not ported but its annular end surface is axially inclined so that when rotated by the element 25 it varies the effective area of one of the ports 12. The bushings 6a, 6b may be secured by radial compression between the members 1, 3 or may be bonded or otherwise connected to them, and a list of suitable rubber compounds for the material of the bushings is included in the Specification. Specification 586,888 is referred to.

Title: Improvements in systems for synchronizing a magnetic tape apparatus with another apparatus
IPC: H04N5/91
Filed: 1961-04-04
Abstract: 915,254. Automatic speed control. AMPEX CORPORATION. April 4, 1961 [April 21, 1960], No. 12061/61. Class 38 (4). In a synchronizing system for a magnetic tape upon which television signals are recorded a reference signal 10 is derived from a local generator during the recording operation and is passed through a sync. separator 12 from which a vertical sync. component is recovered. This component is applied to a phase comparator 14 and to a frequency multiplier 16 developing a sine wave signal. The sine wave signal is applied to a phase shifter 18 which varies the phase of such signal when an error signal is developed at comparator 14. A speed-responsive signal is developed by a photo-cell associated with a scanning-head drum assembly and is applied from terminal 22 to comparator 14. The error signal actuates motor 24 for driving the phase shifter 18, the output of which is coupled to a driving-motor for the scanning drum. The signal from the photo-cell is also applied to frequency discriminator 26 developing a frequency error control signal to control phase modulator 20. During the playback operation, a reference signal from source 28 is channelled to a sync. separator 30 for separation into vertical and horizontal components, the latter having the higher frequency. The vertical component is fed to a frequency multiplier 32 and to a vertical phase comparator 34. The output of the multiplier is applied through phase shifter 36 and phase modulator 38 to control the speed of the motor coupled to the scanning drum. At the same time, a signal is derived from the tape and applied to a sync. separator 40 for separation into vertical and horizontal components, the vertical component being fed to the comparator 34 developing an error signal to actuate relay 42. The relay passes the error signal to the phase shifter 36. The horizontal component derived from the tape is then compared with the horizontal component from the reference source in phase comparator 44, the error signal being applied to modulator 38. This affords small instantaneous corrections for maintaining the angular velocity of the driving- motor and the scanning drum within narrow limits. When the comparator 34 is producing an error signal, the relay 42 connects the comparator 44 to earth, so maintaining the input to the modulator 38 in a steady state condition. A frequency discriminator 46 develops a frequency error signal for controlling the modulator 38.
