Title: Arrangement in a two-for-one spindle for varying the position of one or more control members in a relatively-fixed delivery bobbin carrier
IPC: D01H7/86
Filed: 1966-10-24
Abstract: 1,128,999. Two for one twisting apparatus. PALITEX PROJECT-CO. G.m.b.H. 24 Oct., 1966 [26 Oct. 1965]. No. 47566/66. Heading D1D. 2:1 twisting apparatus has means for controlling the yarn in the stationary bobbin carrier operated by one or more electromagnetic field generators outside the carrier which is or are associated with at least one pulseoperated device in the carrier arranged to respond to pulses from the or each generator so as to change the position of the control means. An "electromagnetic field generator" is defined as an electrical device arranged to vary or produce a magnetic field in response to a signal supplied to it. In Figs. 1, 2, a generator 17 carried by a balloon-restrictor or separator 16 is magnetized at each pulse to repulse a magnet 22 and rock a pivoted lever 21 in the lower wall 5 of the carrier. A spring- urged pawl is thus caused to rotate a toothed wheel 26 carrying an eccentric pin 31 in a slot in a rod 33 guided for straight-line movement. A second pawl 28 prevents retrograde movement of the wheel. The rod is connected by a curved arm 36 to a head 37 disposed in a gap in the wall of the stationary part of the spindle to brake the yarn against a surface 38. The braking-effect obtained is governed by the number of impulses transmitted, and a spring is fitted to the wheel which zeroises it when the retaining pawl is released. In Figs. 5 and 6 the wheel is replaced by a toothed rack which bears by a head 43 against one, 47 of two interconnected fluid-filled flexible members, the other 48 of which bears against a pivoted brake-member 38. The application of the brake is also adapted to brake a let-off flyer 55; to this end, member 48 is connected to a resilient sleeve, adapted, when it is pressurized, to force a member 53 carrying the flyer, against a braking-surface 54 on the upper part of the spindle. In Fig. 4, the generator is a primary coil 17 transmitting across the gap between the separator 16 and the carrier to a secondary supplying a stepwise driven motor 39 carrying a pin 31 operating a rod 33. The field generator may be actuated, so that the brake may be applied to the yarn, by a thread break detector of a device which measures the amount of yarn unwound. It may also be activated by a brake associated with the rotating spindle, to release the yarn brake when the spindle brake is applied, or to apply the yarn brake when the spindle brake is released to start spinning. The generators of each of several spindles of a machine or of several machines can be made to respond jointly.

Title: Microwave ovens
IPC: H03B9/10
Filed: 1976-11-26
Abstract: 1520167 Supply circuits for microwave ovens; RAYTHEON CO 26 Nov 1976 [18 Dec 1975] 49504/76 Heading H2H A microwave oven 10 comprises a magnetron 16 having a power supply circuit including a transformer 40 provided with an output winding 60 coupled to the magnetron, the transformer being fed with pulse energy so that the energy of current pulses supplied to the magnetron varies in dependence on the average flux density in the transformer. When the oven door 12 has been closed and a timer set to the cooking time required for food 14, a start button is pressed to supply power to the cathode heater 68 of the magnetron via a transformer 70. After a delay of a few seconds, a pulse width modulator 82 and a variable pulse width generator 56 are energized. Atransistor 48 is switched on and off by high frequency pulses supplied by the generator 56. During the conductive periods of the transistor, current flows through a winding 38 to increase the flux density in the ceramic core 42 of the transformer 40, and a capacitor 62 is charged via a diode 64. During the non-conductive periods of the transistor, the polarity of the voltage across the winding 60 reverses and is added in series with the voltage across the capacitor 62 to supply a high voltage negative pulse via a diode 66 to the cathode 68. A current pulse flows through the magnetron and the amplitude of the pulse may be varied by adjusting the duty ratio of the transistor 48 by means of a variable timing circuit in the modulator 82. An overcurrent sensor 84 compares the voltage across a resistor 52 with a reference voltage to switch off the pulse generator if a short circuit occurs. In the event of an excessive voltage across the transistor 48, a winding 74 returns current to a power supply 28 via diode 76.
