Title: Liquid-pressure-controlled gas valves for liquid heaters
IPC: F24H9/20
Filed: 1934-01-30
Abstract: 432,779. Valves. DEHN, F. B., 103, Kingsway, London.-(Butzke-Bernard Joseph Akt.-Ges., F.; 12, Ritterstrasse, Berlin) Jan. 30, 1934, No. 35088. Divided out of 432,045, [Group XI]. [Class 135] In a gas-heated liquid heater in which the main gas valve 4 is opened by the pressure of the liquid when a liquid valve 11 additional to the main liquid tap 9 closes or throttles a liquid conduit such as 12, the valve 11 is operatively associated with the pilot gas valve 10 so that it cannot be closed until the valve 10 is opened, or alternatively is closed when the pilot jet 23 is alight. The valve 4, Fig. 1, controlling the supply to the main burner 3 is operated by a diaphragm 8 in a control chamber 7 against the action of a spring 14. The conduit 12 byepasses a throttling device 13 in the main liquid supply pipe 1. Alternatively it may byepass the device 13 without being in direct connection with the control chamber 7, or it may connect the chamber 7 with the chamber 7<1> above the diaphragm 8, Fig. 14, or it may connect the chamber 71 with a point before the throttling device, Fig. 12. The valve 11 may throttle the conduit 1 itself in which case an adjustable plug is arranged on the end of the valve spindle to prevent complete closure of the pipe 1. The valves 10, 11, Fig. 1, have a known type of interlocking means. In the embodiment shown in Fig. 7, the valve 11 controlling the byepass conduit 12 is closed by the expansion of the resilient thermal member 20 by the pilot flame 23. The supply passage 27 to the control chamber 7 is restricted by an adjustable screw 28. Rapid exhaust of the chamber 7 is possible because of the check valve 30. The conduit 12 may be comparable in diameter with the passage 27 and a small valve such as the needle valve 11 may be used. The main water tap 9 may be located at the point of consumption as in Fig. 14, or several places of consumption with associated water taps may be provided. In this case the chamber 7<1> is connected by a pressure equalizing conduit 26 with a point behind the throttle 13. An arrangement is shown in Fig. 12 in which the control chamber 7 is in open communication with the pipe 1 and a passage 35 and a check valve 34 corresponding to the passage 27 and check valve 30 in Fig. 7 are associated with the equalizing passage 26. In a practical embodiment of this form, the passage 26 comprises a pipe socket in an enlargement of which a leaky ball valve is mounted. The socket forms part of the throttling device and a tubular or pot-like membrane corresponding to the diaphragm 8 is stretched over the socket, a piston secured thereto and the piston chamber. The parts associated with the control chamber 7 may easily be adapted to existing liquid heaters. The various alternative arrangements are described in detail in the Specification.

Abstract: 471,459. Automatic control systems. C.A.V.-BOSCH, Ltd., GLASER, W. H., and WOOD, N. R. March, 3, 1936, No. 35516. Divided out of 471,422. [Class 38 (iv)] Electromotive force.- Dynamo regulators employing a carbon pile resistance, the pressure on which is regulated by an electromagnet responsive to variations in the output of the dynamo, are provided with means for producing fluctuations of pressure in the pile in addition to the normal variations of pressure to prevent lag in the action of the resistance. The carbon pile resistance c, arranged in the exciting circuit of the dynamo, is subjected to the pressure of the spring d, this pressure being varied by an opposed electromagnetic force due to the armature g acting through a lever f and push rod c. The electromagnet is provided, in addition to the usual winding h, with a winding i supplied with alternating or intermittent current producing rapid variations of pressure on the pile to avoid lag when the speed of the dynamo is either increasing or decreasing. The varying current may be obtained from special slip rings on the dynamo or from interrupter mechanism.

Title: Improvements in or relating to dehydrated mashed potatoes
IPC: A23L19/15
Filed: 1961-10-02
Abstract: Dehydrated mashed potato which does not turn sticky on reconstitution contains a small amount, e.g. 0.05-1%, on the dry weight, of a natural gum such as carragheen, algin, pectin, low-methoxyl pectin, guar gum, karaya gum, gum arabic, gum tragacanth, gum agar, locust bean gum or gum acacia.  The dehydrated mashed potato may contain also a starch-complexing agent, which forms a hydrophobic substance with the amylose of starch, and renders starch incapable of forming cohesive gel structures.  0.05-1%, on the dry weight, of the starch-complexing agent may be used.  The starch-complexing agent is exemplified by higher fatty acids, i.e. fatty acids of 8 or more carbon atoms, e.g. lauric, myristic, palmitic, stearic, oleic and linoleic acids and the mixed fatty acids obtained by hydrolysis or natural fats and oils or such fats and oils hydrogenated, sodium, calcium, aluminium and magnesium salts of such fatty acids, mono- and di-glycerides of such fatty acids, mono- and di-esters of sucrose and such fatty acids, such fatty acid esters of an inner ether of a hexitol, condensation products of ethylene oxide with mono- or di-esters of such fatty acids with sorbitan and mannitan, lactic acid esters and acetyl tartaric acid esters of mono- and di-glycerides of such fatty acids, a lecithin, a cephalin or a lipositol.  The natural gum may be incorporated in the form of a complex with such a fatty acid and a polyvalent metal, e.g. the substance obtained by adding a water-soluble calcium, magnesium or aluminium salt to an aqueous preparation of the fatty acid or its sodium or potassium salt and the gum or its sodium or potassium salt, 0.1-2%, on the dry weight, of the complex being used.  If the gum is added to the mashed potato before dehydration, a small amount, e.g. 0.1-2%, on the dry weight, of a higher fatty acid triglyceride, e.g. cottonseed, coconut, peanut or maize oil or such an oil hydrogenated may be added.  Specification 925,887 is referred to.

A machine for folding laundry flatwork articles comprises a conveyer having two runs 2 and 12 moving in the same direction, the upper run 2 terminating above the rest position of a travelling carriage 5 which carries means 7 for gripping the leading edge of an article 1 whereby the article is drawn between the conveyer runs until it is released at such a moment that the portion of the article on the upper run feeds on top of the portion on the lower run to form a folded article. A strip light 3 is disposed parallel and above the upper run 2 and photocells 4 and 6 are carried on the carriage 5. When the article blocks the light to both the cells, as in the Figure, the grippers 7 are operated and the catch 8, 14 is released, so that the carriage moves under the action of the weight 9 to draw the article between the conveyer runs until the cell 4 passes the end of the article and is operated by the light. This releases the grippers and operates fingers 13 to engage the tapes of the lower run 12 and so draw the carriage back towards its position of rest until the catch 8 engages whereby the fingers 13 are disengaged.

Abstract: 1,058,691. Steam turbine plant. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 6, 1964 [Sept.12, 1963], No.36027/63. Heading FIT. A turbine power plant includes a higher pressure main turbine supplying a lower pressure main turbine through a reheater, an auxiliary turbine receiving working fluid from the higher pressure main turbine and driving a liquid feed pump, and an automatically controlled flow regulating valve in the conduit between the main turbines arranged to throttle the working fluid flow at low power outputs from the main turbines so as to ensure a sufficient supply pressure of working fluid to the auxiliary turbine. A superheated steam generator 5 supplies high and low pressure main turbines 1H, 1L respectively through an admission control valve 11 interstage reheater 7 and regulating valve 13. An auxiliary turbine 31 driving a feedwater pump 33 receives steam from H. P. turbine 1H through a regulating valve 37 and exhausts to feedwater heater 23. Feedwater heaters 19, 23, 27, 35 also receive bleed steam from the turbines. Over the upper range of main turbine load 3, valve 37 controls auxiliary turbine 31 output in response to feed pump delivery pressure, feed flow, or boiler drum water level. When the main load drops such that turbine 31 tends to receive insufficient steam, unit 39 resets interstage valve 13 so as to throttle the main steam flow and cause a corresponding increase in the inlet pressure at turbine 31. Unit 39 may be responsive to a feed pressure sensor 41, feed flow, boiler conditions, H. P. turbine exhaust pressure, or main turbine output. A small electrically driven stand-by feed pump may supplement or supplant pump 33 at the lowest main loads.
