Abstract: 981,316. Making wire articles. SHIAULIAISKY VELOSIPEDNY ZAVOD. Sept. 5, 1963, No. 35161/63. Heading B3E. A machine for bending wire comprises an abutment, means for laying wire against the abutment, a rotary die with spiral working faces for engaging the wire to each side of the abutment so that the wire is bent partly around the abutment, a rotary part with a longitudinal slot for receiving two free ends of the wire as it is so bent around the abutment, and means for rotating the rotary part so that end portions of the wire are bent in planes at angles to the plane in which the wire is bent around the abutment. Wire 14 is fed by a gripper 8 reciprocated by a cam 10 on a main drive shaft 1 to a position against an abutment 15 where it is held by guides 19. The wire 14 is cut from its supply by a knife 11 operated by a cam 4 on the shaft 1. The severed length of wire is then bent around the abutment 15 to the form shown in Fig. 5 by spiral working faces 13 of a die 12 on the shaft 1, the ends of the wire moving through and out of grooves in the guides 19 into a longitudinal slot 17 in a rotary member 16.

Abstract: 428,632. Air-compressors. SZEKELY, G., 3, Tummelplatz, Graz, Austria. Dec. 14, 1933, No. 35238. Convention date, Sept. 22. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 25, 1934.) [Class 8 (i)] [See also Group XXXV] An electricallydriven air-compressor operated by the oscillating armature 42 of an alternating current electromagnet. The spring - mounting of the oscillating system being tuned to resonance with the periodicity of the alternating current has the magnet body 41 and the armature 42 which together approximate to the closed iron body of a column by the transformer disposed with horizontal and inclined air gaps 45, 45<1> to form an approximately closed iron circuit whose iron path has a low reluctance which is further diminished when the back pressure of the compressed medium displaces rearwardly the central position of oscillation of the armature. The downward movement of the armature supplies air to the working chamber 67 and on the upward stroke this air is compressed with the accumulator chamber 66. The working chamber is limited at top and bottom by apertured diaphragms and plates which act as suction and outlet valves.

Title: Actuators
IPC: F15B15/18
Filed: 1975-08-27
Abstract: 1523453 Reciprocating pumps SPERRY RAND CORP 27 Aug 1975 [28 Aug 1974] 35303/75 Heading F1A [Also in Division G3]  A self-contained hydraulic actuator assembly, e.g. for aircraft control surfaces, comprises a housing 10 enclosing an actuator 12, an electric motor 28 driving a reversible variable displacement main pump 32 and an auxiliary pump 34, and an expansible reservoir 36 connected to the inlets of both pumps, an electro-hydraulic servovalve 66 controlling the displacement of main pump 32, and thus of actuator 12, in response to electric command and feedback signals fed to summer 92. The command signal may be derived manually or by an autopilot. Servovalve 66 varies the pressures in lines 68, 70 to control pistons 76, 78 which adjust the angle of main pump swash-plate 80 in response to the electric error signal from summer 92. A mechanical connection 82 from swashplate 80 to valve 66 feeds back a signal representative of the velocity of actuator piston 14, the main pump being connected to opposite sides of the latter via lines 46, 48 and valve 50. Should the auxiliary pump output pressure in lines 44, 52 fall, valve 50 is spring urged rightwards to connect opposite sides of piston 14 to each other and to reservoir line 56 so that the latter can supply topup fluid to restore pressure. Reservoir 36 is formed by a spring-loaded slidable differential piston 37 defining two reservoir chambers 38, 40 and a pressurizing chamber 42 connected to auxiliary pump outlet line 44. The reservoir feeds auxiliary pump 34 through line 60, the latter also providing replenishment via shuttle valve 62 to whichever of the main pump lines 46, 48 is at lower pressure. Should the pressure in either line 46, 48 become excessive, then valves 86 or 88 bypass the control pressure in line 68 or 70 to tank to reduce main pump displacement. Cooling of the system is effected by a heat exchanger 100 which receives liquid from the sump of pump 32 through the stator/rotor gap of motor 28 and directs it back via lines 102, 104 and filter 106 to reservoir 36. Cooling air is blown through heat exchanger 100 by ram action or by fan 108 driven by further electric motor 107.

Title: Improved manufacture of viscose threads having hollow filaments, and threads produced thereby
IPC: D01D5/24
Filed: 1938-12-05
Abstract: 508,285. Viscose artificial threads. ALSA SOC. ANON. Dec. 5, 1938, No. 35429. Convention date, Dec. 14, 1937. [Class 2 (ii)] Artificial threads having hollow filaments are produced from a viscose containing sodium carbonate, 'any tendency for, the formation of an insoluble double carbonate of soda and lime being removed by incorporating in the viscose, prior to filtration, substances for precipitating the traces of lime introduced for example by the wood pulp. The precipitation of the lime may be effected by means of salts such as oxalates, secondary orthophosphates, metaphosphates, borates, hyposulphites, aluminates and their mixtures with silicates, or by means of soaps such as Marseilles soap or tallow soap. Instead of soap there may be used glycerides, or other esters of higher fatty acids, or these acids themselves, since these substances are converted into soap under the action of the alkali present in the viscose. The precipitant may be added at any point in the preparation of the viscose. Thus, it may be added to the alkali cellulose before xanthation, to the sodium carbonate solution which is incorporated in the viscose, or to the soda lye used in the dissolution of the xanthate. In an example,. stearic acid is incorporated in a viscose containing sodium carbonate, any calcium stearate formed being removed during the subsequent filtration. Specification 255,527, [Class 2 (ii)], is referred to.

[Also in Division G3] An automatic control system for a cutting or like apparatus having a tool 11 driven by an A.C. electric motor 12 and a carriage 17 driven by an electric motor 25 for causing relative movement between a workpiece 16 and the tool 11 comprises a sensor 21 for sensing the load current fed to the motor 12, a comparator for comparing the current with a predetermined value, and power control means for controlling the power supplied to the feed motor which power control means is responsive to an output from the comparator and to the magnitude and phase of the voltage supplied to the motor 12 so as to automatically control the relative movement between the tool 11 and the workpiece 16 whereby the power absorbed by the motor 12 tends towards a desired valve. As shown in Fig. 2, the system includes a transistor 43 to the base of which is applied (a) a signal representative of load current exceeding a predetermined value, this signal being derived from the sensor 21 by way of a setting resistor 38 and a reference Zener diode 44, and (b) a signal derived from a transformer 26 having its primary winding connected to the supply for the motor 12, this signal rendering transistor 43 conductive in the absence of an output from the Zener diode 44. The output from the collector of transistor 43, which output is interrupted when the load current exceeds its predetermined value, is applied over a capacitor 45 to control a thyristor 40 in circuit with the armature 35 of the feed motor 25, this circuit being connected across the output from the transformer 26 and receiving a voltage representative of the magnitude and phase of the voltage supplied to the motor 12, and the motor 25 is thus controlled in such a manner that the carriage 17 is moved relative to the tool 11 at a rate sufficient to maintain the power absorbed by the motor 12 constant. A braking diode 46 may be connected across the armature 35, and the system may include limit switches to reverse the direction of the motor 25 when the carriage reaches the end of its travel towards the tool 11. A modified arrangement, including a sensitivity control circuit is described with reference to Fig. 4 (not shown).
