Title: Improvements in and relating to the automatic control of the delivery of conveyors
Inventor: RAYDEN RAYMOND GEORGES
IPC: G01G11/04
Filed: 1956-09-17
Abstract: 822,743. Automatic control systems for conveyer belts. BRITISH THOMSON-HOUSTON CO. Ltd. Sept. 17, 1957 [Sept. 17, 1956], No. 28358/56. Class 38 (4). A mechanical feeder comprises a conveyer and weighing means for the material thereon, a feeder supplying the material and an adjusting device, for varying the delivery of the conveyer, which is controlled to produce a constant feed by an electric motor controlled by a magnetic amplifier having a control coil, the signal for which is derived from a movable member of a variable inductor responsive to the weight of material on the conveyer. The feeder is driven by shunt motor 1, in accordance with the movements of weighbeam 13, to vary correctively the supply of material. The movement of the weighbeam is transmitted to the core 12 of a variable inductor 11 which controls the direct current in the control winding 9 of magnetic amplifier 6. The amplifier D.C. output is applied to load potentiometer 15 from which a voltage is tapped and fed, in series opposition with mains 4, to the field winding 2 of motor 1. The switch 16 enables the control action to be overridden when necessary.

Title: Improvements in or relating to tuning devices and indicators for radio receivers
IPC: C07D295/084
Filed: 1939-10-24
Abstract: 535,904. Wireless receiving sets. STANDARD TELEPHONES & CABLES, Ltd., and SMYTH, C. N. Oct. 24, 1939, No. 28596. [Class 40 (v)] The manual tuning shaft of a receiver is associated with an electro magnet fed with A.C. under the control of the A.V.C. circuit of the receiver so that the shaft is vibrated in dependence on signal strength, the vibration being at a maximum when the receiver is mistuned and diminishing as the receiver is brought into tune, absence of vibration thus indicating correct tuning. A spindle A rotated by a knob G drives the tuning elements through a pulley P and cord H. The spindle is mounted in bearings D permitting a small degree of vibration limited by a spring F and is provided with a thickened conical portion C serving as an armature within a coil B. Vibration is imparted to the shaft by feeding low frequency alternating current or direct current superposed with a low frequency current to the coil B which is in series with a valve the grid of which is controlled by the A.V.C. voltage.
Patent GB-1101968-A (GB)
Title: Motor vehicles with power take-off
IPC: B60K17/28
Filed: 1966-06-27
Abstract: 1,101,968. Variable speed control. GENERAL MOTORS CORPORATION. 27 June, 1966 [16 July, 1965], No. 28605/66. Headings F2C and F2D. In a motor vehicle wherein an engine (2) drives the vehicle wheels (5) through a hydrodynamic torque converter 4 and change gear (4a) and also drives an accessory (6 through a hydrostatic transmission (8, 9), the torque converter has variable-angle reactor blades 18 movable by a servo-piston 30 under the control of a valve 44 between a first position providing maximum torque-converter capacity and a second position providing reduced torque-converter capacity which allows both the vehicle and accessory to be driven simultaneously without reduction of engine speed. Axial movement of the piston 30 acts through cranks 32 to vary the angle of the reactor blades 18. As shown a passage 35 permits converter pressure to urge the piston 30 right against the pressure supplied to the chamber 36 from the valve 44. Pressure from a line 50 supplied through a restriction 72 to a chamber 62 moves the spool of valve 44 down against the bias of a spring 46 to exhaust the chamber 36 whereupon converter pressure moves the piston, 30 right and reduces the angle of the blades 18 for high capacity converter operation. For low capacity converter operation a valve 80 is opened to supply pressure air from a source 81 to a piston 84 which moves up together with a plunger 86. A projection 86a of the plunger 86 opens a ball valve 74 to vent the chamber 62 at 68 and permit a spring 46 to move the valve spool 44 upward and thus supply regulated pressure to the chamber 36 which pressure moves the piston 30 left to increase the reactor blades angle. The pressure is regulated by the pressure acting in a chamber 56 opposing the action of the spring 46. The regulated pressure and thus the high angle blade position may be adjusted by changing the number of washers 58 below the spring 46. In Fig. 2a (not shown) the ball valve (74<SP>1</SP>) is normally held closed by the plunger (86<SP>1</SP>) and is opened by cutting off the air supply. In Fig. 3 (not shown) the reactor blade angle of a twin-turbine torque converter is urged toward a high-angle position by converter pressure and towards a low-angle position by pressure liquid supplied from the valve (140). The piston (154) controlling the ball valve (144) is operated by pressure liquid from the hydrostatic transmission (8, 9) driving the accessory. With the ball valve (144) closed a low regulated pressure is supplied to a chamber (112) which opposes the converter pressure on the piston (106) to determine the high angle low capacity position of the reactor blades. When the ball valve (144) is open a high pressure is supplied to the chamber (112) to move the blades to their low angle high capacity position.

Proofing against vermin; proofing-compositions -Wool, fur, hair, feathers, and the like are protected against attack by moth by treatment with an arylsulphonic acid amide or a derivative or substitution product thereof in which compounds the hydrogen atoms of the amino groups may be wholly or partly replaced by alkyl, aryl or aralkyl groups. All the nuclei may contain further substituents, including aryl and aralkyl residues, containing one or more sulphonic acid amino groups, e.g. a compound of the general formula R-SO2-NH-R-SO2NR1R2 in which R = an aromatic nucleus and R1 and R2 = hydrogen, alkyl, aryl or aralkyl. The protective compounds or their alkali salts are absorbed by the material from an acid bath (with or without addition of salts, acids or wetting agents) or the free compounds may be applied in solution in organic solvents. The materials may be impregnated and dyed simultaneously. A list of compounds is given. The use of dyestuffs containing arylsulphonamide groups is excluded. In examples (1) material is impregnated with 3 per cent of the sodium salt of 4-chloro-11-phenol-2 : 6-disulphobis-4<1>-chloroanilide in aqueous solution with addition of acetic or sulphuric acid, (2) bis-1 :2 5-trichlorobenzene-4-sulpho-1<1>:3<1>-phenylenediamide is used as in the first example, (3) material is impregnated with a 3 per cent benzine solution of 1:2:5-trichlorobenzene - 4 - sulpho-3<1>-valerylamino-4<1>-chloroanilide.
