Title: Apparatus for indicating or recording fluid pressure
IPC: G01L9/00
Filed: 1945-07-23
Abstract: 596,152. Lamps. RONNEBECK, H. R., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 23, 1945, No. 18802. [Class 75 (iv)] [Also in Groups XXXV, XXXVIII and XL] Fluid pressure is applied, e.g. through diaphragm 15 and stem 14, to vary the area of contact between two resilient transparent members 10, 11, e.g. of glass or quartz, so as to control the amount of light from a source 7 falling on a photo-electric cell 2. The light is internally reflected in member 11 except where members 10, 11 are in contact. To avoid variation of intensity of the light source 7 with ambient temperature, it may be enclosed by a jacket in which liquid at constant temperature is circulated; alternatively, it may be surrounded by a temperature variable resistance in the supply circuit, so that as temperature increases, the resistance increases and current through the lamp decreases.

Title: Improvements in or relating to the automatic control of turbo-alternators
IPC: H02P9/06
Filed: 1928-06-29
Abstract: 320,038. Imperial Chemical Industries, Ltd., and Warren, T. R. June 29, 1928. Running generators in parallel.-The load distribution amongst groups of alternators driven by turbines operating at different working pressures is automatically controlled to maintain the pressure in an intermediate receiver, supplying .steam also for auxiliary purposes, at a desired value. Fig. 1 shows a group of turbines A supplied from a high pressure main B, and exhausting into an intermediate pressure main 0 from which a constant supply is required ior auxiliary purposes, a condensing group A' supplied from the intermediate pressure main and a group A<2> similarly supplied and providing exhaust steam for feed water heating. The steam supply to the group A<2> may be automatically controlled in accordance with feed water conditions. The turbines are controlled by standard frequency generator K<1> and by a group of synchronizing relays L, M, N according to Specification 303,779, responsive to the relation between the standard and system frequencies, which, in combination with load sharing relays Q - - Q<2> govern the supply of current to raise speed contactors H or lower-speed contactors J operating upon reversible pilot motors controlling the turbine throttle valves to maintain a desired load distribution as well as a constant frequency. To maintain constant steam pressure in the intermediate main C, which may also be supplied from low pressure boilers, a pressure regulator R governs the supply of control current to the turbines of groups A and A<1>. To control the supply of exhaust steam from the turbines A<2> the control current thereto may be governed by means S responsive to the feed water condition. Diminution of pressure in the main 0 may be prevented by a pressure regulator U, set lower than the regulator R, controlling a pilot motor on a bye-pass valve T to supply high pressure to the main. The arrangement shown is adapted to permit the automatic synchronization of additional machines but a simplified arrangement in which the relay M, suitably adjusted, is connected directlyto transformer winding 0<2> may be used where this provision is not needed. The system operates upon a variation in the system load and frequency to supply control current intermittently to the pilot motors and thus produces a gradual approach to synchronism and the desired load distribution, a timedelayed interrupter N increasing the amount of interruption as the synchronism is reached. Means other than those described may be employed for frequency control or load distribution control.

[Also in Division F4] A valve for use in a vehicle heating system comprises an inlet 2 and two outlets 3, 4 controlled by flap valves 5, 6. The flap 6 is rigidly mounted on a spindle 7<SP>1</SP> while the flap 5 is rigidly mounted on a concentric inner spindle 7<SP>11</SP>. A lever arm 8 is fixed to the spindle 7<SP>1</SP> and the spindle 711 carries a toothed wheel 9 which meshes with a wheel 14 formed on a lever 11 and rotatable on the lever 8. The flap 6 is loaded in the closed position by a magnet 17 such that when the lever 11 is actuated by a push rod 12, the lever 8 is prevented from rotating and the wheels 9, 14 rotate to open the flap 5. When the flap 5 is fully opened, further movement of the rod 12 opens the flap 6 through the lever 8 moving both flaps to a position closing the duct 3. The flap 5 also carries a magnet 16. The duct 3 leads to a de-mister or de-icer nozzle while the duct 4 leads to the vehicle interior. The rod 12 may be actuated manually or by a temperature responsive device. The valve may also be used as a mixing valve in which case, the ducts 3, 4 are the inlets and duet 2 is the outlet.

Title: Improvements in and relating to electric switch devices for movement detection
IPC: E05F15/00
Filed: 1947-07-16
Abstract: 624,949. Door-operating apparatus. PETERS & CO., Ltd., G. D., SWAIN, L. W., and PIERCEY, R. J. July 16, 1947, No. 18919. [Class 65 (i)] [Also in Group XXXVII] An electrically-controlled, pneumatically-operated door system of a vehicle has a switch device to prevent the opening of the doors when the vehicle is running, and to close the doors if open when the vehicle starts. This switch device comprises an electromagnetically operated friction clutch having a driving plate 14 splined onto a shaft 10 driven from the transmission system of the vehicle, the driving plate being biased into engagement with the driven plate 20 of the clutch by a spring 15. An arm 39 fixed to the plate 20 is biased to a mid position by springs 41, 42 supported on a fixed part 37 of the switch housing 2. The movement of the plate 20 is limited by stops 35, 36 carried by it, which co-operate with fixed adjustable abutments 33, 34. These stops also serve to close contacts 28, 29 carried by a fixed insulating plate 27. Assuming that the doors are open and that the vehicle starts to move, the shaft 10 rotates and the plate 20 is turned against the action of the springs 41, 42. One of the stops 35, 36 closes the contacts 28, 29 and the other in abutting one of the abutments 33, 34 prevents further movement of the plate 20, the clutch then slipping. The closing of the contacts 28, 29 results in the energisation of electromagnetic valves (not shown) to effect the closing of the doors. The coil 18 of an electromagnet is energised when the doors close, to withdraw clutch plate 14 to prevent wear of the friction surfaces. The plate'20 is then returned to its mid position by the springs 41, 42 and the contacts 28, 29 are reopened.

Title: Improvements in or relating to textile treatment
IPC: D06M13/52
Filed: 1950-07-28
Abstract: In the fulling or milling of textile materials consisting of or containing wool, the material is treated during the operation with an aqueous medium containing a nitrogen-free surface-active primary or secondary ester of orthophosphoric acid having at least one hydrocarbon radical of at least 6 carbon atoms.  The esters may be obtained from mono- or polyhydroxy compounds containing at least one hydrocarbon radical of at least 6 carbon atoms.  These compounds may contain saturated or unsaturated aliphatic, aliphatic-aromatic, alicyclic or heterocyclic radicals.  These radicals may be joined to the phosphorus atom directly or via intermediate polyhydroxy compounds such as sorbitol, erythritol, glycerol and glycol; polyethers and mixed ethers of these compounds, e.g. their condensation products with ethylene oxide may also be used.  The orthophosphoric esters thus include those of the type R-O-X-O-PO(OH)2, where R is a lipophilic radical containing the hydrocarbon radical of at least 6 carbon atoms and X is a hydrophilic radical, e.g. the radical of a polyhydric alcohol or an etherified alcohol still containing at least two free hydroxy groups. Advantageously, the partial esters of orthophosphoric acid are used in conjunction with ortho phosphate tertiary esters, in particular those of the type RO-P.O(OX)(OY), where R is as defined above and X and Y are lipophilic or hydrophilic radicals.  The radicals R, X and Y may contain free hydroxy groups which may be esterified, e.g. with phosphoric acids.  The tertiary esters preferably contain hydrotropic groups rendering the esters emulsifiable, dispersible or soluble in water.  Examples employ aqueous fulling baths containing (1) mono-cyclohexyl orthophosphate ester; (2) secondary orthophosphate ester of the condensation product of octadecyl alcohol with 8 mols. of ethylene oxide and the tertiary ester of the same alcohol; or (3) the primary ortho-phosphate ester of dibutyl cresol, the pH being adjusted where necessary by means of formic acid.  The cloth treated in (3) is spun from rags torn in a bath containing a neutral ester of ortho-phosphoric acid with 2 mols. of ocenol etherified with 4 mols. of ethylene oxide, and 1 mol. of triglycol; the wetting action of this bath may be increased by addition of various specified wetting-agents. Specification 354,300 is referred to.

Abstract: 691,069. Detecting broken threads photoelectrically. GENERAL ELECTRIC CO., Ltd., and WARD, L. G. July 31, 1951 [Aug. 1, 1950], No. 19232/50. Class 40 (iii). Broken threads are detected by a photoelectric cell which receives a narrow light beam scanning a region which the broken thread will enter. As shown warp threads in a loom pass from bobbins 20 to a roller 21. Beneath the threads are situated two housings each containing a photo-cell 10, and a light source 11. The light sources each form a narrow beam of light which is reflected from one of mirrors 13, to the photo-cells. The lamp and cell assemblies are oscillated through the angle 12 by a motor 15 and rod 14. So that a broken thread shall interrupt the light beam a gentle stream of air from a nozzle 23 blows on the threads so as to deflect broken threads downwardly. Both cell assemblies feed a common amplifier to stop the machine or operate a warning device. In a modification, Figs. 3 and 4 (not shown), the lamp and cell are mounted at one end of a carriage which is traversed to and fro beneath the threads and at the other end of which is a plane mirror. The stream of air may be ionized.
