Title: Improved flying machine
IPC: B64C27/10
Filed: 1927-12-28
Abstract: 295,177. Honacker, Y. van. Dec. 28, 1927. Helicopters; propelling; steering and balancing; emergency fittings.-A machine is supported by two oppositely rotating rings of blades, the inclinations of which can be varied cyclically by the pilot to give a forward propulsion or to steer the machine, the two rings being mounted on a central shaft which can be detached with the pilot's seat from the body when necessary to enable the supporting system to act as a parachute. In normal straight flight the blades of the two rings reach their maximum inclinations on opposite sides of the machine. The blades are mounted on radiating lattice arms 11 connected to tubular hubs 7, 8 and braced at their ends bv tension members. The blades can move radially on their supports which are provided with helically twisted members engaging rings on the blades so that the inclination of the blades is varied as they move radially. The hubs 7, 8 rotate about a column 5 which is connected by a releasable clutch 4 to the main bodv of the machine. In the form shown in Fig. 1, the hub 7 is driven by an engine 2 and the hub 8 is driven by bevel gearing from the hub 7, but 'n the form shown in Fig. 2 both hubs are driven by gearing at their lower ends. A fan 26 may be provided for cooling the engine. The blades are normally pulled outwards radially by springs but are drawn in by cables 18 connected to rings 19 running around rollers 27, Fig. 5, on frames 28 capable of being displaced by a screwed shaft 34 turned by chain gearing 31 from a hand wheel 32. Where no steering rudder is provided, the shaft 34 is divided and moved by two hand wheels to enable a differential eccentering of the rings 19 to be produced for steering purposes, but the two hand-wheels can be clutched together so as to move as one. A rudder and elevator of cross-formation universally pivoted at 25 is shown in Fig. 1.

Title: Switching systems for electrically-driven washing machines
IPC: D06F39/00
Filed: 1956-11-16
Abstract: 814,488. Switching systems. PFENNINGSBERG, P. Nov. 16, 1956 [Jan. 5, 1956], No. 35155/56. Class 38 (4). [Also in Group XXXVII] An automatic washing machine is driven by an electric motor having two separate windings one of which is effective for reversibly rotating the cylinder of the machine during the actual washing operation, and the other providing for more rapid rotation of the cylinder in one direction for centrifuging. A cycle of operations is started by manual actuation of a control drum which is afterwards driven by a pilot motor LM. Controller contacts W1 are closed initially to energize coil ZV so that a valve is opened to admit water into the cylinder whereby a switch LS is actuated by the rising water level. A relay RS is then energized to close contacts R1-R3 in the circuit of the reversing winding. Heaters for a boiler and for the washing container are energized at the same time. Opening of contact R5 closes the admission valve, but, if the water-level should drop, the switch LS is actuated temporarily to re-open the valve. Closure of contact R6 energizes the pilot motor LM and, after the first washing period, the controller opens contacts W2 so that no further water can enter through the admission valve. Controller contacts W3 are then actuated to energize coil AV and open a drainage valve, this being followed by the response of relay SS. This relay closes holding contacts S5 as well as contacts S1-S3 for energizing the centrifuging winding of the motor, the opening of contacts S4 de-energizing the relay RS. The centrifuging operation is interrupted by the opening of the contacts W3 and, during the period in which the contacts W3 hesitate in opening, the energization of coil AV and the pilot motor are maintained through contact R7. Shortly before the interruption of current at contacts W3, the admission valve is opened and, when the switch LS is actuated, the reversing relay responds to start another washing operation, a signal lamp ZL being energized. At the end of this washing period, the drainage valve is opened, the centrifuging relay is energized, and the reversing relay is disconnected. Following this operation, the drainage valve is closed and the admission valve is opened independently of the switch LS, the cylinder being reversed while fresh water is continuously admitted. Towards the end of this rinsing period, the drainage valve is opened at the same time as the admission valve. A number of centrifuging periods followed by rinsing periods may then take place, the cycle coming to an end at the termination of a centrifuging period due to the opening of contacts W1, W3. The controller driven by the pilot motor may have different sets of contacts which are brought into operation selectively according to the desired washing programme. In other arrangements, two controllers are driven selectively by a single motor, or two controllers with individual driving motors are provided, Figs. 2, 3 and 4 (not shown).

Addition to 371,213. [Class 41.] The process according to the parent Specification is modified by the use of a saturated solution of chromic acid as the electrolyte in the preliminary coating of the counterelectrode and also if desired in the coating of the articles. Using alternating current of 40-60 volts at a bath temperature 40-60 C., treatment for 20-30 minutes is necessary. In the preparation of a counterelectrode two plates of an alloy containing 3-4 per cent copper, 0À5-1 per cent manganese, 0À5 per cent magnesium and the remainder aluminium may be treated as electrodes. One plate is found after treatment to have a hard, nearly uncoloured glass-like coating, and the other a pearl grey coating. Either may be used as the counterelectrode in the subsequent treatment of articles, the coating on the articles being glass-like. The coating on the counterelectrode after the second treatment is pearl grey in both cases. Treatment of an aluminium alloy containing 4 per cent copper, up to 2 per cent silicon, 0À3 per cent iron, and of pure aluminium is also described. The electrolyte may be saturated at room temperature or at the working temperature. The coatings may be washed and painted or dyed.

Classes 40(5) and 40(6) In a junction transistor circuit a reactive impedance is arranged in the emittercollector circuit which together with the phase shift occurring between the base and emitter currents makes the total exceed ninety degrees so that a negative resistance component appears in the base input impedance. An oscillator may be produced by employing an inductor L in the base lead', Fig. 1 (first Provisional Specification) the resistor RE and capacitor C forming the reactive impedance. Frequency modulation may be affected by varying the collector potential. The oscillator may be stabilized by a crystal X or series tuned circuit, Fig. 1 (second Provisional Specification) the reactive load being the circuit CE LE which is adjusted to be capacitive at the operating frequency. Amplification of signals from a source G, Fig. 6, feeding a load RL may be obtained by interposing a negative impedance circuit comprising a transistor with base impedance L and emitter reactive load REC, Rb serving as a base bias resistor, and Cb as a blocking capacitor. The resistor RL may be replaced by a transmission line, so that amplification takes place equally in both directions. The emitter circuit may be formed by a parallel circuit tuned to be capacitive at the operating frequency. According to the first Provisional Specification a point contact transistor may be employed and pulses generated by including an inductor in the collector lead shunted by a diode.

Title: Permanent setting of wool and wool-containing articles
IPC: D06C29/00
Filed: 1970-07-23
Abstract: 1321266 Permanent setting of wool garments COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANISATION 23 July 1970 [28 July 1969] 35822/70 Heading D1P A method for permanently setting wool articles, which have been partially set, comprises treating them with unsaturated steam under conditions of pressure, temperature and relative humidity at which the rate of permanent setting is greater than the rate of release of cohesive set. The wool article may be steam pressed for 5 to 10 seconds, then exposed to unsaturated steam at a suitable temp. and r.h. The temp. and regain of the wool are the most important parameters in determining the correct conditions for the method and generally the regain of the wool is approximately within the limits corresponding to those obtained when wool is exposed to 80 to 95% r.h. in steam at atmospheric pressure at a temp. of 100 to 106.5C respectively. Preferably the wool is heated to above the required temp. e.g. in an oven, steam is introduced and the temp. allowed to fall to that corresponding with the required r.h. and held for the required time. After the wool has been in the correct part of the critical region for an adequate time to acquire sufficient set without losing any crease sharpness, the wool is either removed or the steam allowed to become saturated. The wool article may have been subjected to shrink resist treatment and the partial setting treatment may have involved the use of a setting agent e.g. sodium bisulphite.

Abstract: 1,015,692. Control systems for arc-welding apparatus. PULSE ARC WELDER CO. Sept. 20, 1962 [Sept. 27, 1961], No. 35897/62. Heading H2H. Arc welding apparatus comprises circuitry which is in a number of parts, as shown three, one part of which is utilized for striking the arc, the second part of which is for centring the arc and cleaning the end surfaces of the arc electrodes and the third portion of which is used for performing the welding operation. A capacitor 46 is charged to a high voltage by the winding 34 of a transformer 26 over a rectifying diode 44. When a trigger mechanism is operated a capacitor 160 energizes the operating coil 158 of a relay 54 to close contacts 52, 56 whereupon the capacitor 46 discharges by way of a transformer 62 into the gap between electrodes 14, 16 to ignite the arc. A second capacitor 86 is charged by the transformer 26 over a doide 78 to a voltage determined by a Zener diode 88. Thus when the arc voltage produced by the pulse from the capacitor 46 falls to the voltage to which the capacitor 86 is charged this capacitor 86 will discharge into the arc to maintain it and will also provide sufficient energy to cause the arc to assume the shortest path between the electrodes 14, 16 and to burn off any scale or oxides which exist on the electrode surfaces. A third capacitor assembly 148 is charged by the transformer 26 over a full wave rectifier 100, 102 and transistors 114, 118 to a voltage determined by a Zener diode 134 and a potential divider 126, 128, 130. When the arc voltage has fallen to this value the capacitors 148 will discharge into the arc to complete the welding operation.
