Title: Timing apparatus for use in centrifugal separators and the like
IPC: B04B11/04
Filed: 1942-08-28
Abstract: 557,407. Centrifugal machines. BRITISH SUGAR CORPORATION, Ltd., and MACKENZIE, A. D. Aug. 28, 1942, No. 12179. [Class 23] The treatment of sugar in a centrifugal machine is controlled by a timing device which determines the interval between the starting of the machine and the turning on of the water, the duration of the water flow and the time when the discharge of syrup is changed from one trough to another. A shaft 13 is rotated stepby-step by means of a power driven lever 22 and a pawl 21. The shaft carries a cam formed of part of a cylinder bounded by an axial edge 10a and a helical edge 10. The cam contacts a bowl 37 on bar 36 forming part of a frame 32, 33, 36 which is coupled to a lever 43 controlling the water supply. The bar 36 can be moved to left or right by turning a screw 34 to bring it into line with a narrower or wider part of the cam and so to alter the duration of the water flow. The cam 10 is carried by discs 11, 12 and the disc 11 is coupled to the shaft 13 by a vernier clutch 17, 18. By this clutch the position of the leading edge of the cam, in relation to the starting position of the shaft 13, can be varied and, consequently, the interval before the turning on of the water. A pin 25 on the cam disc 12 raises a lever 50 which turns a latch lever 47 and releases a trip 45 to permit a weighted chute to transfer the delivery of syrup. The lever 50 is pivoted at 51 to a lever 52 and, by adjusting the latter, the moment when the trip 45 is released is varied. In the initial position, the ratchet wheel is held by notched lever 26 which engages a pin 24 on the clutch disc 18 and the pawl 21 reciprocates idly at a pace where one tooth of the ratchet wheel is missing. To start an operation a hand lever 29 is depressed, this moves a lever 30 to engage a pin 31 and lift the lever 26 clear of the pin 24 and at the same time to move the ratchetwheel through one tooth space.

Title: Improvements in the production of dyeings of animal fibres
IPC: D06P1/00
Filed: 1940-07-31
Abstract: 542,936. Dyeing textiles. SOC. OF CHEMICAL INDUSTRY IN BASLE. July 31, 1940, No. 12398. Convention date, July 4, 1939. [Class 15 (ii)] Fast dyeings are produced on animal fibres, e.g. wool or silk, by applying thereto a watersoluble acyl derivative of a sparingly soluble dyestuff wherein the group determining solubility in water is contained in the acyl residue (cf. Specifications 480,358, 482,184 and 505,504) and thereafter steaming to eliminate the acyl residue. The steaming may advantageously be effected in presence of a hygroscopic substance, such as urea, glycerol, acetin, glycol, thiodiglycol, monoethylurea or benzylsulphanilic acid, and, if desired, of an acid-binding buffer substance, such as trisodium phosphate. In examples, (1) woollen muslin is printed with an aqueous paste containing the acylation product from benzoyl chloride-3-sulphonic acid and the ternary condensation product from cyanuric chloride (1 mol.), 2-aminoanthraquinone (2 mols.) and aniline (1 mol.), urea, glycerol, starch tragacanth thickening and trisodium phosphate and the printed material is dried, steamed for 70 minutes, rinsed, soaped, rinsed and dried to obtain fast intense yellow print ; (2) woollen muslin is padded in an aqueous bath containing the acylation product from benzoic acid-3-sulphochloride and the azo dyestuff, 2 : 5-dichloraniline# the 2<SP>1</SP>-anisidide of 2 3-hydroxynaphthoic acid, urea and glycerol and the material is squeezed, dried, steamed and further treated as in (1) to obtain a fast scarlet dyeing which can be discharged. Prints or dyeings are similarly obtainable with the condensation products from (a) benzoyl chloride-3-sulphonic acid and 4-chloro-2-methosyaniline# the anilide of 2 : 3-hydroxynaphthoic acid (red), (b) benzoic acid-3-sulphochloride and 5-nitro-2-toluidine# the 2<SP>1</SP>-anisidide of 2 : 3-hydroxynaphthoic acid (bordeaux), (c) benzoic acid-3 : 5-disulphochloride and 2 : 5- dichloroaniline# the 2<SP>1</SP> : 5<SP>1</SP>-dimethoxyanilide of 2 3-hydroxynaphthoic acid (brown).

Title: Control systems
IPC: G05D1/00
Filed: 1955-04-29
Abstract: 784,344. Automatic steering control systems. SPERRY CORPORATION. April 29, 1955 [June 10, 1954], No. 12501/55. Class 38 (4). In a closed sequence automatic control system an electrical signal representative of the output of a servomotor is applied to means which respond to incorrect operation when the electrical signal contains a component having a frequency in excess of a predetermined value. As shown, the invention is applied to the elevator channel of an aircraft automatic pilot in which (a) an A.C. signal derived from a pitch pick-off 11 of a gyro vertical 10 is applied to an amplifier 12 controlling the excitation of a generator 29 supplying a servomotor 14 to operate the elevators; (b) a follow-up signal from an elevator pick-off 26 is fed back to the input of amplifier 12 which develops and adds a differential component of control; (c) a selector swicth 47 may be operated to apply to amplifier 12 an additional signal from either (i) an instrument landing radio receiver 39 to maintain a predetermined path; (ii) a pick-off associated with a bellows 40 to maintain a predetermined altitude; or (iii) a manually-operated device 45. For monitoring purposes the output voltage of generator 29 is applied through leads 48 to a relay winding 51 in series with a condenser 52 to eliminate components having a frequency below a predetermined value. Components having a frequency above this value which result from incorrect operation of the automatic pilot, are effective to operate relay 51 and disengage the automatic pilot by switching off a motor 31 driving generator 29. To prevent such disengagement due to a manoeuvre initiated by the radio receiver, altimeter or manual control, the signal from switch 47 is rectified at 57 and applied through leads 58 to relay 51 to oppose and cancel the voltage from generator 29. A network 59 is provided to simulate the performance of the servo system. Signals from switch 47 which have a rate of change exceeding a predetermined value develop in a differentiating circuit 66 a voltage sufficient to operate a relay 70 which opens the circuit of relay 51 and thereby prevents the monitoring circuit from disengaging the automatic pilot under these conditions. Specifications 629,104 and 663,913, [Group XXXVIII], are referred to.

The trigger T and sear S are pivoted respectively on pins 2, 3 carried by a member L shown in plan in Fig. 3. Between them, and seated in a recess 7 in the trigger, is a spring-urged member D adapted to trip the sear when the trigger is pulled. Pivoted on the trigger-pin 2 is a yoke Y having a forwardlyextending finger 11 adapted to be raised by a projection on the cartridge follower when the magazine, which is situated immediately in front of the frame F, is empty, whereby the yoke Y is caused to rotate the member D into a position in which it cannot trip the sear, which therefore remains in bent and holds the breechholt retracted until the magazine is removed.
