Title: Improvements in or relating to methods for preparing sausages or the like
IPC: A22C11/00
Filed: 1958-09-11
Abstract: 895,101. Skinless sausages. HILGELAND, P. H. Sept. 2, 1959 [Sept. 11, 1958], No. 29182/58. Class 49. Skinless sausages and other skinless agglomerations of meat or fish are manufactured by ejecting the meat from a stationary nozzle out of contact with a hot emulsifier bath comprising a substantially neutral ortho- or anhydrophosphate or a citrate in aqueous solution and, if desired, seasoning, and immediately thereafter plunging the ejected sausage meat into the bath, whereby the outer meat layer is cooked and hardened. The meat, which may itself incorporate emulsifier, e.g. similar to that in the bath, is immersed for preferably five to three minutes at a bath temperature of from 130‹ to 180‹ F., followed by a five-minute cooling of the hot meat in a bath at just above freezing-point. The meat may, however, be completely cooked, if desired, e.g. to produce sausages for canning, by maintaining the hot emulsifier bath at 160 ‹ to 212‹ F. and immersing the meat for five to thirty minutes, in which case no after-cooling is required. Meat is ejected from a stationary nozzle 2 into a compartment 3 in a wheel 4 rotating intermittently in a hot bath 6, a portion cutting device (not shown) dividing the meat into suitable lengths. After immersion the meat in the compartment 3 is pushed out by a rod into a chamber 8 of a conveyer belt 9 which takes the sausage through a cooling bath and a drying chamber in which hot air at 160‹ F. is circulated.

Title: Improvements in the manufacture of the thiosulphates and seleno-sulphates of the alkali metals, calcium and ammonium
Inventor: LEVENSON GERALD ISAAC PASTERNA
IPC: C01B17/64
Filed: 1951-12-14
Abstract: <PICT:0713559/III/1> A method of preparing the thiosulphates or selenosulphates of the alkali metals, ammonium and calcium, comprises digesting the corresponding sulphite with sulphur or selenium in the presence of a cationic surface-active agent.  Preferred surface-active agents are alkyl pyridinium halides in which the alkyl group comprises an aliphatic chain of at least six carbon atoms, e.g. dodecyl pyridinium bromide, cetyl pyridinium bromide, decyl pyridinium bromide and octyl pyridinium bromide.  The process permits operation below the melting point of sulphur and may be continuous. In an example, 50 parts by weight of crystalline sodium sulphate (Na2 SO37H2O), 7 parts by weight of finely divided sulphur and 10 parts by weight of water containing 1/100 parts of commercial cetyl pyridinium bromide "Fixanol C" (Fixanol is a Registered Trade Mark), are mixed and digested at 85 DEG -95 DEG  C. for about 15 minutes, the solution is then filtered to remove the unused sulphur and crystallised to separate the sodium thiosulphate.  Fig. 6 shows a flow diagram for a continuous process embodying the invention, sulphur, sulphite, and the cationic surface-active agent are fed from the vessels A, B and C, respectively, into the mixer D whence the mixture passes into a steam jacketed reactor E.  The unused sulphur, filtered off at F is fed back to A while the filtered liquid is fed to a dehydrator or crystallising plant G.  In the case of the preparation of sodium or ammonium thiosulphates, the filtered product is suitable for use as a photographic fixer (see Group XX).

Title: Process for the simultaneous removal of oxides and reducing compounds of sulphur other than oxides from gases
IPC: B01D53/48
Filed: 1963-07-26
Abstract: In a process for the simultaneous adsorption of oxides of sulphur and one or more reducing compounds of sulphur other than oxides from gases containing them in total concentrations up to 10% by volume, at temperatures above 50 DEG  C., by means of carbonaceous adsorbents, the spent adsorbents being regenerated by heating to 300 DEG  C. to 500 DEG  C., a molar ratio of between 1.1 and 3.5 to 1 is maintained between the sulphur in the oxides and the sulphur in the reducing compounds other than oxides, and the adsorbents are regenerated to convert the free sulphur formed from the reducing sulphur compounds during the adsorption completely into sulphur dioxide by chemical reaction with <PICT:1016269/C1/1> the sulphuric acid formed in the adsorbent. The required molar ratio in a gas mixture initially containing an excess of reducing sulphur compounds is attained by (a) precombusting a proportion of the gas to be purified, or (b) returning a proportion of the sulphur dioxide formed during the regeneration back to the gas prior to the adsorption.  In the drawing, a is a source of waste gas, b is a precombustion furnace, c and e are adsorption sections, d is a gas cooler, f is the desorption (regeneration) unit and g the heater for the unit, and l is a return duct to recirculate to a point prior to the adsorption sections part of the sulphur dioxide formed in f.  Regenerated adsorbent is discharged from f, screened at i and returned to the adsorption sections by means of elevator k.

Abstract: 1418907 Bearings ROLLS-ROYCE (1971) Ltd 20 June 1973 [23 June 1972] 29695/72 Heading F2A [Also in Division F1] A bearing assembly comprises a rolling bearing 29, a housing 30, and a frangible member 42 connected either to the bearing or to the housing and disposed therebetween, wherein the member defines together with the bearing a first space 32 and together with the housing a second space 33, each space being adapted to contain a hydrodynamic squeeze film wherein one film is operable under normal conditions to damp vibrations between the bearing and the housing, and the other film is operable only after excessive forces on the bearing have caused fracture of the frangible member. The bearing is particularly for mounting a rotor shaft of a gas turbine engine, and the increased radial movement afforded by fracture of the frangible member is such as to allow inversion of the shaft. The member is frangible by virtue of two portions 43, 44 of reduced thickness formed by machining annular grooves 45, 46 in the member. Relative rotation of the outer race and the housing is prevented by the inter-engagement of dogs 34, 35. A plurality of frangible portions may be used to produce a radial stack of squeeze films.

Abstract: 533,485. Valve amplifying and modulating circuits. PHILIPS LAMPS, Ltd. Nov. 10, 1939, No. 29848. Convention date, Nov. 10, 1938. [Class 40 (v)] Relates to high-efficiency modulated carrierwave transmitting systems in which, as in Specification 493,667, four amplifiers successively supply energy, at different values of the highfrequency amplitude, to a common load impedance, and comprises an arrangement in which all the amplifiers can be earthed without resorting to inductive coupling between the amplifiers and the load. Of the four amplifiers 1, 2, 3, 4, Fig. 3, amplifier 1 operates as a Class B amplifier, amplifier 2 is a Class C amplifier with a threshold voltage smaller than the unmodulated carrier voltage, and amplifiers 3, 4 are Class C amplifiers with threshold voltages equal to each other and larger than the unmodulated carrier voltage. The amplifiers are arranged in the order shown, and between them are connected phase-inverting networks 14, 24, 19 of which the two outer networks have surge impedance of value ¢R, and the middle network a value R; whilst the load of impedance #R is connected across the amplifier 4. The networks may comprise pi-sections having series inductance and shunt combinations of parallel inductance and capacity. Adjoining shunt elements may be combined with corresponding elements of neightbouring networks. The modulated wave is supplied to the various amplifiers at such phase angles that all the energy reaches the load in like phase. In a modification, Fig. 4 (not shown), the load impedance is equal to ¢R and is connected between the amplifier 3 and the network 24. When the system is used for modulation, the carrier wave and the modulating voltage are jointly fed to the valve grids.

Small amounts of organic solvents such as chlor or nitrobenzene, acetone or trichlorethylene may be added, and the tar oil may be chlorinated, nitrated or sulphonated.  In the treatment with compositions containing wool oil, the tar oil may be removed by steam distillation, leaving the wool oil on the fibre as lubricant in subsequent spinning &c.
