Title: Improvements in or relating to temperature responsive control devices
IPC: G05D23/12
Filed: 1947-10-13
Abstract: 658,744. Cooling discharge apparatus. IGRANIC ELECTRIC CO., Ltd. Oct. 13, 1947, No. 27411. Convention date, Oct. 12, 1946. [Class 39 (i)] [Also in Group XXIX] A cooling system for an electron tube 1 comprises an inlet 5 and an outlet 6 for coolant, the outlet connecting with a Venturi tube 3, the depression at the throat of which actuates a diaphragm 19 to close a protective switch 2 for the electron tube when the coolant flow is above a minimum value, and a temperature responsive bellows 26 around which the outflowing coolant passes. Excessive temperature of the outflowing coolant causes the bellows to expand and throttle an orifice 28 sufficiently to reduce the rate of flow of coolant below the minimum value, thereby causing the switch to be opened.

Title: Process for dyeing and printing fibrous materials of cellulose esters
IPC: C09B19/00
Filed: 1930-09-15
Abstract: Cellulose esters, dyeing; printing; vat dyes, dyeing with.-Cellulose ester fibrous materials are dyed or printed by causing them to absorb a leuco compound of a gallocyanine dyestuff and thereafter developing the colour by oxidation.  The following examples are specified: (1) Acetate silk is printed with an aqueous preparation containing leuco Prune pure, gum thickening, turpentine oil, and sodium chlorate, dried, steamed for 1 hour and washed to obtain a vivid deep violet fast to washing and rubbing. (2) Acetate silk is printed with a similar aqueous preparation containing leuco Corein RR as the dyestuff ingredient and further treated as in (1) to obtain a deep vivid blue of similar fastness. (3) Acetate silk is printed with an aqueous preparation containing the leuco anilino-compound of Corein RR, ethylene glycol, gum thickening, turpentine oil, and sodium chlorate, dried, steamed for 1 hour and washed to obtain a brilliant greenish-blue fast to washing and rubbing.  (4) Acetate silk yarn is dyed a vivid greenish blue very fast to washing and rubbing by treatment for 1 hour in a dyebath containing the leuco anilino-compound of Corein RR, ethylene glycol, and hydrosulphite NF conc. with gradual raising of the temperature to 80-85 DEG  C., air being preferably excluded, washing, and oxidizing at 40-45 DEG  C. with sodium perborate solution.

Title: Motor control servo system
IPC: H02P23/00
Filed: 1965-06-29
Abstract: 1, 084, 840. Automatic speed control. CONTINENTAL OIL CO. June 29, 1965 [Aug. 24, 1964], No. 27547/65. Heading G3R. A D. C. motor 20 driving magnetic tape drum 22 has its speed selected by switch 28, a photoelectric chopper 24 delivering a feedback signal whose frequency indicates the actual speed of the motor. A reference oscillator 150 is associated with multi-vibrator 154 providing outputs A, B, of opposite phase which are further divided to provide reference frequency outputs C, D, phasedisplaced by ninety degrees. The motor feedback frequency on line 90 has a fixed value when the motor is correctly following the set speed, no matter where the switch 28 is positioned. Changes of frequency of the signal on line 90 are indicated by variations in the spacing of square wave pulses derived from multi-vibrator 96, these pulses being filtered to afford a D. C. signal on line 92 representing the actual motor speed. A phase detector 102 compares the signals on lines 90, 107, to derive a D. C. signal on line 94 having an amplitude indicating the phase difference and a polarity indicating the direction of the phase-shift. The reference frequency signal on line 142 is fed to converter 36 providing a D. C. signal on line 148 proportional to the desired motor speed. The signals on lines 92, 94, 148, are applied to summation networks 166, 168, connected to differential amplifier 170, a further feedback signal being taken from the output of this amplifier and applied through capacitor 228 and one of the attenuation resistors 230-233 to the network 168. This further feedback signal consists of sampling A. C. variations in the output of amplifier 170 and is fed back to the input degeneratively. The velocity-reference and phase-feedback signals are summed in network 166 and the summed voltage is applied to one input of the differential amplifier; likewise, the velocity-feedback and amplifierfeedback signals are summed in network 168 and the resultant voltage is applied to a second input of the amplifier. The output of the amplifier 170 is a direct voltage which is amplified by power amplifier 40 to drive the motor 20. In the event of a sufficient overspeed condition, the control voltage on lead 238 becomes positive and the power amplifier is switched to provide a reverse braking voltage for the motor. A protective circuit 41 is responsive to the motor feedback frequency signal on lead 290 to open contacts 294 when the speed is double its normal value. The motor remains de-energized until a reset switch is opened.

Title: Improvements in and relating to gas producers
IPC: C10J3/34
Filed: 1921-06-15
Abstract: 185,980. Climie, W. June 15, 1921. Charges, agitating.-In a gas-producer, a rake structure, comprising two members having curved portions 24 and flat portions carrying racing-teeth 22 and cutting-knives 23, is carried by two sliding rods 16 mounted in a rotating cylindrical casing 10 centrally arranged at the upper part of the producer. The rods 16 are guided by rollers 19 and pass through openings in a dividing wall 11 in the casing 10, sleeves 18 being arranged around the openings to provide water seals. A variable counterbalance 26, preferably a water tank, regulates the pressure of the rake on the fuel bed. The rake is water-cooled and consists of two boxes 33, 34 arranged on opposite sides of a cross-rod 17. The cooling-water is supplied through one of the sliding rods 16 and passes to one end of the rod 17 and, say. the box 33; thence through a connection 35 to the box 34, and out through the other half of the rod 17 and the other rod 16. The direction of rotation of the rake is such that the curved surfaces 24 always tend to keep the rake on the top of the fuel bed. The teeth 22 and knives 23 are arranged with their edges tangential to their circles of motion. The body of the producer is formed by a double watercontaining casing 1, 2, and in the upper part of the producer is a coil 29 through which the feedwater for the water space 3 may be passed. One or more brushes 30 may be secured to the cylinder 10 for sweeping the inner surface of the upper part of the producer.

Abstract: 756,870. Incubators. HAMNETT, J. Aug. 12, 1954 [Oct. 8, 1953], No. 27662/53. Class 5 (2). In an incubator having an angularly displaceable, preferably cylindrical, egg container 1, the eggs are held in clips 28 so that they can be tilted in such a way as to keep the large ends above the small ends. Air is drawn into the container by a fan, passes over a heating unit 15, along the axis of the container and through screens to the egg trays 24, foul air escaping through an axial opening. The trays are perpendicular to the axis of the container and the clips are so attached to the trays that the long axes of the eggs lie in the direction of the axis of the cortainer and, as the container rotates, the large ends of the eggs are kept above the small erds. In a modification, the clip is attached to a spring which sags downwards under the weight of the egg and provision may also be made to give a rocking movement to the egg.
