Title: Improvements in or relating to compressors
IPC: F01D5/14
Filed: 1962-07-03
Abstract: 951,713. Axial-flow compressors. GENERAL DYNAMICS CORPORATION. July 3, 1962 [July 5, 1961], No. 25533/62. Heading F1C. A blade structure suitable for use as one stage in an axial-flow compressor comprises at least a row of impulse rotor blades, and a stator blade section including a row of reaction blades and a row of impulse blades. Impulse rotor blades 11b<SP>1</SP> are followed by reaction stator blades 12a<SP>1</SP> and impulse reaction blades 12b<SP>1</SP>. The blades 11b<SP>1</SP> may be preceeded by reaction rotor blades 11a<SP>1</SP>. The reaction blades 11a<SP>1</SP> and 12a<SP>1</SP> effect a static pressure rise by diffusion but deflect the gas through a small angle only. The impulse blades 11b<SP>1</SP>   and 12b<SP>1 </SP>turn the gas through a large angle to reverse the circumferential component of gas velocity; since this is done without appreciable pressure increase, expansion and other losses are small. The stator blades are mirror images of the respective rotor blades, and the pressure rise in the stator is substantially equal to that in the rotor, i.e., the reaction blading is of 50 % reaction type. Alternate impulse blades (those not in alignment with the preceding reaction blades) may be omitted. There may be a small pressure drop in the impulse blading, with a corresponding small increase in gas velocity. An additional row of reaction rotor blades may be provided in the final stage of the compressor to reduce the exit whirl. Specification 931,930 is referred to.

Title: Improvements in operating mechanisms for electric switches
IPC: H01H71/50
Filed: 1921-09-29
Abstract: 187,811. Coates, W. A., and Metropolitan-Vickers Electrical Co., Ltd. Sept. 29, 1921. Automatic circuit-breakers; actuating.- In a switch the contacts depend from a member 15 which is of cradle-shape and reciprocates vertically. A trip member is provided between this member 15 and the operating linkwork 36 whereby the member 15 descends to open the switch independently of any movement of the linkwork 36, which itself is collapsed to reset the trip member after the switch is open. The linkwork carries rod 34 from which depend stirrups 31 engaging flat parts 30 of cut-away parts 29 of shafts 18 rotatably mounted in the member 15. From Fig. 5, it is seen that the weight of the member 15 and contacts &c. tends to rotate these shafts in the directions of the arrows but, as seen in Fig. 4, triggers 22 engaging the pins 24 in the lever 26, pivoted at 27 to the member 15, prevent this rotation until the solenoid 42 trips them when the member 15 &c. falls and the switch opens. The linkwork 36 is retained by catches 41 which are tripped by the falling of member 15 when opening the switch, the linkwork then collapsing, rod 34 falling, and the triggers 22 re-engaging the pins 24 by means of a spring 28 connected between the triggers. To close the switch, upward force is applied to the point 39 when the entire mechanism is reset. In Figs. 7, 8, the catch 41 is replaced by a set toggle mechanism 48, 49, which is similarly tripped. Springs 57 may be provided to assist opening.

Abstract: 412,536. Supports for electric incandescent lamp filaments. PETROWITZ, F., 6, Hogelmiillergasse, Vienna. Sept. 19, 1932, No. 26064. Void [Abridged as open to inspection under Sect. 91 of the Acts, Sept. 20, 1932]. [Class 39 (ii).] Tubular electric incandescent lamps are provided with a main and an auxiliary filament, the latter being of such resistance that it only glows dimly when the main filament is intact, but gives a substantially normal illumination upon the destruction of the main filament. In one form the tubular lamp 1, Fig. 1, has bipolar terminals 2, 3 at each end connected to leading in wires 4, 5 and 6, 7 respectively, these leading- in wires being connected to branch members 8 .. 11 and 12, 13 which support short lengths of filament 14 ... 18 and 19, 20 respectively. Upon the failure of one or more of the filaments 14 ... 18 a greater proportion of current passes through the filaments 19, 20. In a modification the main filament through the lamp is carried on pig-tails 22, Fig. 2, mounted on a glass rod 23, while two glass tubes 24, 25 contain conductors 26, 27 respectively to convey current to supports 28 ... 33 for auxiliary filament lengths 35 connected in parallel. Arcuate wire springs 34 fused into the glass rod 23 bear upon the inner wall of the tube to provide a resilient support. In another form adapted for tubes of various shapes a flexible suspension wire 44, Fig. 5, carries radial supports 48 for glass beads 49 into each of which two pig-tails 50 are fused. The pig-tails respectively support a filament 51 clamped at both ends directly to the lamp terminals, and two auxiliary filaments 52, 53 which are connected to the suspension wire 44 by return leads or conductors 46, 47 adjacent to a glass bead 45 dividing the wire 44 into two parts providing return paths for the current. The leading-in wires may terminate in hooks or loops at the ends of the tubes to enable a number of lamps to be connected readily in series or parallel.

Title: Improvements in or relating to the preparation from wood fibre, or other like material, of cellulose, for use in the manufacture of viscose and other useful material
IPC: D01F2/06
Filed: 1930-09-03
Abstract: In a process for the conversion of wood, fibres' or the like into viscose, the wet cellulose pulp obtained from the wood &c. by the usual methods is dried slowly by the gradual application of heat but without the application of pressure so as to leave the fibres loose and receptive to the alkali lye used in the preparation of viscose. The complete conversion from wood &c. to viscose and artificial silk, films, and the like, is conveniently carried out as one uninterrupted process, although wet cellulose pulp containing not less than 20 per cent of water may be used as the initial material, the drying being then carried out as indicated above.  An example is given in which the drying is carried out by means of steam pipes laid beneath a lattice floor.

Abstract: 916,007. Transistor circuits. YAMAMOTO, M., and ABE, A. July 20, 1961, No. 26300/61. Class 40 (6). [Also in Group XXXVI] In apparatus for detecting the presence of conductive or magnetic bodies of the type described in Specification 910,630, extra stages are provided to control a motor-controlling relay 6. The sensing coil 8 forms part of a 1000 kc/s. oscillator 1 the output of which is normally taken across a resonant circuit 2 tuned to the same frequency, negative halfcycles being passed by a diode 22 to maintain transistor 26 conductive. Transistor 27, forming part of a Schmitt trigger circuit, is therefore non-conductive, transistor 28 conductive and transistor 40 non-conductive so that the relay 6 is not energized. When an iron or non- ferrous body is brought within the vicinity of the sensing coil 8, the frequency of oscillator 7 is changed so that the voltage passed by diode 22 is insufficient to maintain transistor 26 conductive. The Schmitt trigger circuit comprising transistor 27, 28 changes state, rendering transistor 40 conductive and energizing relay 6. The supply voltage is stabilized by a Zener diode 47.
