Abstract: 1,068,352. Drying apparatus. WHIRLPOOL CORPORATION. Feb. 10, 1965 [Feb. 28, 1964], No. 5846/65. Heading F4G. The invention relates to a tumbler drying machine of the kind in which ring electrodes in the drum discharge a capacitor 113 through wet clothes, until the required dryness is reached whereupon the capacitor discharges through a discharge tube 115 to switch off the heater 103, and motor 16. According to this invention a recycling relay 130 is provided to extend the operation and ensure the clothes are fully dried. In operation when the capacitor first discharges through the tube 115 and the base-emitter circuit of transistor 116 to cut off S.C.R. 97 for about half a second, and de-energize relays 82, 130. However, as relay 130 releases slowly a circuit is maintained for about a second over contact 132 so that relay 82 picks up when S.C.R. 97 conducts again, and drying is continued while the capacitor 113 recharges through resistors 109, 109, and 112, and eventually discharges through tube 115 to terminate the operation.

Title: Improvements in or relating to navigational control devices comprising a directive radio antenna
IPC: G01S19/27
Filed: 1942-05-07
Abstract: 557,385. Automatic control systems for directional wireless aerials and dirigible craft. BENDIX AVIATION CORPORATION. May 7, 1942, No. 6169. Convention date, May 7, 1941. [Class 38 (iv)] Altitude; steering.-To enable a craft to be steered manually or automatically along a straight course to a radio transmitter a directional aerial on the craft is automatically controlled so that it tends to maintain a defined angular relationship with the earth's magnetic field. An aerial loop 52 is first set manually by depressing a knob 77 and turning it to operate an autosyn transmission 65, 60 until a right left indicator 95 gives a nulf indication. A scale 72 then indicates the angular relation between the loop and the earth's field and the pilot or automatic pilot operates the controls to maintain the indicator 96 in the null position during flight. The loop 52 is however electrically associated with means responsive to changes in the relation between the earth's field and the craft. A circular core 14 of magnetic material having radial limbs 11 ... 13 traversed by the earth's field is saturated twice in each cycle of A.C. supplied to a coil 18 so that the resulting changes in flux in the radial limb generates in coils 15 ... 17 voltages which excite coils 25 ... 27 on a core 29 to produce an alternating field therein, the axis of which corresponds with the direction of the earth's field. A core 30 is coupled to the rotor 63 of the autosyn receiver 60 and to an indicator 49 constituting a repeater compass. When the knob 77 is released a switch 80 is closed and contacts engaged by the indicator 96 energize a reversable motor 81 causing the autosyn transmission 65. 60 to operate the rotor 63 in accordance with any displacement of the aerial from its null relation to the radio beam due, for example, to drift. The rotor 63 turns the core 30 in its field and a coil thereon generates a voltage which is amplified and fed to a winding of a two phase motor 39 whereby the aerial loop and stator of the autosyn are actuated to correct the relationship. The turning of the craft, due to the action of the pilot or auto-pilot, at the same time causes a shift on the axis of the field in which the core 30 lies so that the aerial is additionally influenced and displaced from its null position being thereby maintained at an angle to the earth's field corresponding to that on the scale 72 when initially adjusted. The craft is thereby returned to the predetermined course line since the system is quiescent only in that condition. Specifications 549,528 and 550,399, [both in Group XXXVIII], are referred to.

[Class 92 (ii)] Relates to breech mechanism in which to open the breech the breech block A is first moved parallel to the gun's axis and then swung upwardly about an axis E parallel to or coincident with the gun trunnions. According to the invention, eccentrics D are provided on the swing axis E and are connected on each side of the gun barrel Y to the breech block A by straps X and rods F, the eccentrics being moved by an operating-lever C. This lever is first lifted to rotate the eccentrics and move the breech block backwards until it is clear of the gun barrel, further movement of the lever then tilting the breech block upwardly about the axis E to expose the gun chamber for loading. The eccentrics are in dead-centre position when the breech is closed. The lever C is provided with a grip-operated catch G to engage a stop b on the barrel to retain the lever and breech block in the open position for loading, the inserted cartridge being retained by a spring detent k. On closing the breech, a spring plunger N engages a fixed cam Q to cock the firing pin M into engagement with a sear m. The sear is released through Bowden wires by trigger-grips on gun-aiming handles K, L and both handles must be gripped before the gun can be fired. The firing mechanism is protected by a shield U.

Abstract: 1,088,144. Tube mills. POLYSIUS G.m.b.H. Feb. 16, 1965, No. 6562/65. Heading B2A. [Also in Division G3] To maintain the total quantity of material constant in a grinding mill having coarse and fine grinding chambers and return of coarse material from the fine to the coarse chamber, the quantity of fresh material fed to the mill is automatically controlled in dependence on the noise from both chambers of the mill and the rate of coarse return. As shown, ground material from a mill 1 is transported by a conveyor 6 through a sieve 8 to a main outlet 10. Grit separated by the sieve is returned to the mill by a weighing conveyor 12. The rate of supply of fresh material to the mill by a conveyor 19 is determined by the speed of a motor 18 which is controlled at 17 by a signal from a microphone 14, mainly responsive to noise in the coarse section of the mill, to maintain noise level constant. The noise level datum is automatically adjusted by a signal from weighing conveyor 12, responsive to the rate of flow of grit, to compensate for changes in the proportion of grit which are not adequately accounted for by mill noise. The fineness of the grit separated by sieve 8 is automatically adjusted by means 22 in dependence on the load on a motor 5 driving conveyor 6.
