Abstract: 519,734. Treating textiles with resins. SCHUBERT, H., SCHUBERT, H. A., SCHUBERT, B., and SCHUBERT, E. Sept. 28, 1938, No. 28255. Convention date, Oct. 4, 1937. [Class 15(ii)] , Textile materials are treated with an artificial resin condensation product and an artificial resin polymerization product, both formed in situ by heat treatment. The materials are rendered crease-resisting, less liable to shrink or swell and of improved handle; they may be stiffened or loaded. The treating solution may also contain catalysts or anti-catalysts, protective colloids or dispersing agents. As condensation resins there may be used phenolformaldehyde or urea-formaldehyde resins, as polymerized resins there may be used polymerized styrol, acrolein or vinyl compounds. In examples (1) cellulose hydrate fibres are treated with a solution containing phenol, formaldehyde, formic acid, polyvinyl alcohol, ammonium acetate and fatty alcohol sulphonate as protective colloid ; the material is dried and heated for 10 mins. at 120‹C. ; (2) cellulose hydrate fibres are saturated in a solution containing urea, thiourea, hexamethylene' tetramine, common salt, ammonium acetate, tartaric acid and glyoxal; the material is dried and heated for 20 mins. at 120‹C.

Title: Improvements relating to gas turbine plants
IPC: F02C1/08
Filed: 1948-11-03
Abstract: 657,330. Air and gas turbine plant. BOLSEZIAN, G. Nov. 3, 1948, No. 28552. Convention date, Nov. 3, 1947. [Class 110(iii)] [Also in Groups XII and XIII] In a plant comprising a turbine-compressor set actuated by heated-air in a closed circuit and an open circuit gas turbine actuated by gases from a combustion chamber supplied with air from the closed circuit, a part of the heated air is added to the combustion products and passes to the gas turbine. The air is heated as it passes in an annular stream surrounding and in contact with a central stream of combustion products. Air from a compressor 2, Fig. 1, passes, in part, to a combustion chamber 11 and, in part, to the annular space surrounding the chamber. The central stream of combustion products and the enveloping stream of air are divided by the lip of the conduit 13. The combustion products and a part of the heated air pass to a conduit 16 leading to the extraction turbine 4. The larger part of the heated air passes to a conduit 15 leading to the air turbine 3. In the space surrounding the central stream of combustion products there is a deeply corrugated metal annulus 12. as shown in development in Fig. 2, which takes up radiant heat from the hot gases and gives up heat to the air stream in which it is submerged. Some of the air passes finally through a heat-exchanger 14, the other part of which is traversed by the hot gases going to conduit 16. The make-up compressor 1, the compressor 2, the turbines 3, 4 and a generator 5 are on one shaft and run at a constant speed. Or, the make-up compressor and its turbine may be on a separate shaft and run at a variable speed. Or, as shown in dotted lines, an additional compressor turbine set 19, 18 may be on a separate shaft. In the Specification as open to inspection under Sect. 91, a plant is described in which the air is heated in a heat-exchanger through one pass of which the combustion products flow. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in electric motors
IPC: H02K17/14
Filed: 1929-09-20
Abstract: 337,906. General Electric Co., Ltd., and Saunders, N. F. T. Sept. 20, 1929. A.C. induction machines; armatures, cooling and ventilating.-In a squirrel-cage induction motor, the primary of which is adapted to give more than one pole number, the rotor bars are divided into sets, each of which has separate end rings, and the rings of different sets are connected by resistances through which current flows only when operating on the higher pole numbers. For the low pole numbers, the currents in the various sets are independent. The number of sets is equal to the ratio of a larger to a smaller number of poles, and the number of resistances between adjacent rings is equal to the lower pole number. In the form shown, the thirty-two bars of the rotor of a 4 or 8-pole motor are divided into two sets, and each set is divided into groups. One set comprises groups 1, 3, 5 and 7 connected between the end rings 9 and 10, and the other set is composed of groups 2, 4, 6 and 8 between rings 11 and 12. During four-pole operation, current flows in the direction of the single arrows, and as the resistances 13-20 are connected across substantially equipotential points, they do not increase the rotor resistance, whereas they do increase it during eight-pole operation since the currents then flow in the direction indicated by double arrows. The invention is applicable to machines arranged for more than two pole numbers, additional end rings and sets of resistances then being required. Preferably the resistances are in the form of arms' extending radially from a ring or hub concentric with the rotor shaft, and' may be so shaped and inclined as to act as a fan.

Title: Process and apparatus for the preservation of meat products
IPC: A23L3/005
Filed: 1958-09-05
Abstract: In the preservation of non-homogeneous meat, e.g. ham, by placing the meat in contact with at least two pairs of electrodes and charging the electrodes with low frequency alternating current until the meat has reached the temperature necessary for preservation, the power supply on each pair of electrodes is made a function of the difference in temperature between that pair of electrodes and the average temperature between all the pairs of electrodes present, such that the power supply is highest on the pair of electrodes between which the lowest temperature is measured.  The power supply on a pair of electrodes may be temporarily reduced if the temperature of the meat between that pair of electrodes is higher than that between an adjacent pair of electrodes.  Voltages of 50 to 150 volts are preferably employed. According to an example, 4420 grams of fresh, salted ham were pressed by a plunger under a pressure of 3 kg./cm.2 in a rectangular press made of non-conducting material and fitted with three pairs of water-cooled, stainless steel electrodes.  A terminal voltage of 55 volts at 15 amps per pair of electrodes was applied.  The voltage on each of the pairs of electrodes was regulated with a variable ratio-transformer adjusted by means of a servomotor, which in turn was regulated through three resistance thermometers mounted respectively between a pair of electrodes, such that the voltage of a pair of electrodes increased when the matching temperature was lower than the average temperature and vice versa. After eight minutes, during which the temperature of the ham had risen from 20 DEG  to 80 DEG  C., a side wall of the press was removed, the treated ham being pressed by the plunger into a tin; the filled tin was sealed, placed in boiling water for 5 minutes and subsequently kept in a water bath at 70 DEG  C. for 1 hour.

Title: Radio diversity receiving system
IPC: H04B7/12
Filed: 1959-08-21
Abstract: 911,611. Radio receiving systems; automatic phase control. STANDARD TELEPHONES & CABLES Ltd. Aug. 21, 1959 [Aug. 26, 1958], No. 28646/59. Class 40 (5). In a diversity receiving system the intelligence bandwidth of the signal derived from one channel is divided into a plurality of contiguous bandwidth segments, and the phase of that portion of the signal occurring in each segment is adjusted to phase coincidence with the corresponding bandwidth portion of the intelligence signal of another receiving channel prior to combining the intelligence signals of the respective channels. The invention is applicable to space and frequency and also to tune diversity systems if appropriate delays are used. Signals received in antenna 1 are amplified and the intelligence band fm derived in known manner. Signals in antenna 2 are similarly amplified and the intelligence band fm is derived by mixers 14, 14a . . ., and divided by band-pass filters 16, 16a ... into frequency segments (o - #), (# - 2#), . . . and ((n - 1)# - n#). The outputs of these filters are applied to phase detectors 17 which each produce a control signal proportional to the phase difference between the respective filter output and the corresponding bandwidth segment of the output of mixer 11. These control signals are applied via low-pass integrating networks 18 to adjust the frequency/ phase of local oscillators 15 to bring the respective pairs of compared signals into the phase relationship which gives zero output. The outputs of the filters 16 are applied to respective resistors 19 and that from mixer 11 is applied to a resistor 20 whereby the outputs are combined. A ninety-degree phase-shifter 21 may be required in the output from mixer 11 depending on the type of phase detector used at 17.
