Title: Improvements in Relays Operated by Fluid Pressure, especially intended for use in the Control of Gun Mountings.
Inventor: HENDERSON JAMES BLACKLOCK
IPC: F41G5/04
Filed: 1916-02-15
Abstract: 124,503. Henderson, J. B. Feb. 15, 1916. Mountings.-Relates to relays of the fluidpressure type employed in the control of gun mountings by gyroscopes or other controlling- mechanism, and consists in providing two oppositely-rotating motors of the Pelton-wheel type and in controlling, by the gyroscope or other mechanism, a movable jet of water, steam, compressed air, or other fluid, so that it impinges on one or other of the wheels, or passes between the two wheels, the jet being linked to the valve-gear or other part operated by the relay so that it is brought to the inoperative position after a certain movement of the part is effected. In the form illustrated, the wheels 1, 2, Figs. 1 and 3, are mounted on parallel shafts 3, 4 so that a fluid jet .from a nozzle 6 may impinge on either wheel or may pass freely between them. The nozzle is pivoted about an axis 7 and is supplied through a flexible pipe 8. The rotation of either wheel is transmitted by pinions 12 on each wheel shaft to a spur-wheel 14, which, through a screw 15 and nut 16, operates the valve 19 of a motor, or operates any other required part of the device under control. The nozzle 6 is operated, through the levers and links 8<a>, 9, 10, 11 by the gyroscope &c. As the lever 10 is pivoted to the nut 16, the nozzle is returned to the inoperative position after a certain movement of the valve, or corresponding part, has been effected. The spur gear. ing may be replaced by belt, chain, or worm gearing, and in the latter case, the arrangement shown in Fig. 5 is employed, in which the worms 12a, 13<a> on the shafts 3, 4 operate worm-wheels 21, 22, and a differential gear 23, 24, 25, 26 is employed to transmit the motion to the screw 15. The'wheels 1, 2 may rotate in the same direction, a reversing-motion being interposed between one wheel and the part controlled.

Abstract: 555,497. Cutting and polishing diamonds &c. ASQUITH, Ltd., W., BURNESS, T. P. N., and JOHNSON, A. Feb. 21, 1942, No. 2318. [Class 60] A dop appliance for use in cutting and polishing diamonds &c. is provided with an indexing device the operation of which can be seen, felt and heard, and for this purpose the dop 1, Fig. 1, is formed with a spigot-secured in a holder 3 by means of a conical nut 7, the holder being rotatable in a sleeve 14, after slackening a nut 9. The holder is furnished with a transverse slit 11 in its head fitted with a spring-influenced plunger 12 engaging one of a number of radial slots 16 in the sleeve. One side of the end of the plunger is inclined to co-operate with the inclined sides of the slots whereby the holder 3 may be rotated to engage the plunger with another slot. The compression of the spring 13 enables this action to be felt by the operator while the ensuing click and protrusion of the end can be both heard and seen. The sleeve 14 is secured by a nut 20 in a support 17 which is journalled in a castor 18 having means for locking it in an angularly adjusted position. The support is mounted on journal pins 23, 24 by screws 22, and a wing nut 36 and friction washers on one end of the pin 24, the other end 24a of which is shouldered, enables the support to be fixed in its adjusted position which can be read by means of a pointer 28a and scale 28 on the castor and support respectively. A V-shaped member 31, constituting a tool holder, can be similarly clamped in an adjusted position by a wing nut 35. The castor 18 is carried by a swivel pin 40 to which it is secured by a nut 40c and which can be adjustably secured to a supporting arm 42, Fig. 4, by a nut 40f, the arm 42 being provided, between its ends, with adjustable legs 42c.

Title: Esters of n-(1-methyl-3-keto-1-butenyl)-n-(2:3-dicarboxy-3-keto-1-propenyl) amine
Filed: 1952-03-07
Abstract: The invention comprises esters of the formula <FORM:0721349/IV (b)/1> where R is a hydrocarbon radical and preferably a lower alkyl group of 1-6 carbon atoms, and the preparation of the compounds by reacting an ester of hydroxymethyleneoxalacetic acid with iminoacetylacetone or by reacting the ammonium salt of an ester of hydroxymethyleneoxalacetic acid with acetylacetone.  The esterifying groups may suitably be methyl, ethyl, hexyl or benzyl groups.  In examples: (1) and (3) ethyl hydroxymethyleneoxalacetate is treated with iminoacetyl acetone to give N-(1 - methyl - 3 - keto - 1 - butenyl) - N - (21 : 31 - dicarbethoxy - 31 - keto - 11 - propenyl) amine; and (2) the same product is obtained by treating ethyl hydroxymethyleneoxalacetate ammonium salt with acetyl acetone.  In examples (1) and (3) above, the ammonium salt of ethyl hydroxymethylene oxalacetate is obtained as a by-product. Hydroxymethyleneoxalacetic acid esters are made by treating an ester of an etherified hydroxymethyleneoxalacetic acid with alkali and acid in sequence.  For example, ethyl hydroxymethyleneoxalacetate is prepared by treating ethyl ethoxymethyleneoxalacetate with sodium bicarbonate and subsequently acidifying with hydrochloric acid. Alternatively crude ethyl ethoxymethyleneoxalacetate, obtained by the reaction of ethyl oxalacetate and ethyl orthoformate in the presence of acetic anhydride is treated with sodium bicarbonate followed by acid to give a product containing 71 per cent of ethyl hydroxymethylene oxalacetate as estimated by precipitation of the copper complex salt.  Specification 721,348 is referred to.

Title: Improvements in rotary regenerative air preheaters
IPC: F28D19/04
Filed: 1950-02-02
Abstract: 671.717. Thermal regenerators. LJUNGSTROM, F. Feb. 2, 1950 [Feb. 3, 1949; Feb. 15, 1949], No. 2720/50'. Class 64(i) The heat expansion of the rotor of a rotary regenerator is controlled by a fluid traversing channels provided in the rotor and separated from the passages for the flue gases and air in the regenerative mass carried by the rotor.. The purpose is to reduce and stabilize distortion of the rotor, and so reduce leakage. In addition, the parts of the rotor adjacent to the channels can be kept at a temperature above the dew-point of the flue gases, to prevent corrosion. In the form shown, water or other liquid or vapour flows from a pipe 64 through a hollow shaft 36 into a hub chamber 68, then through alternate radial passages 69 in partitions 40 to the annular passage 71 in the outer cylindrical wall 42 of the rotor, back through the intermediate radial passages 69, into a second hub chamber 70, and then to the outlet end of the hollow shaft. Fluid also passes through passages 75, 77, 79 in the rotor casing. The fluid may flow through a circuit containing cooling and heating devices. Alternatively the passages in the rotors may form a closed chamber in which the enclosed liquid is vaporized in one part and condensed in another. The channels within the rotor may be heat insulated. They may be tubes assembled to form radial arms connecting the hub to peripheral tubes at the top and bottom of the outer cylindrical wall of the rotor. The rotor and casing passages may be connected in separate circuits so that the rotor and casing may be maintained at different temperatures. At starting the casing, and later the rotor; may be at the higher temperature.

Abstract: 1,123,752. Electric waffle iron. SUNBEAM CORP. 18 Jan., 1967 [4 April, 1966], No. 2748/67. Heading A4D. A combined waffle baker and grill comprises upper and lower housings 12 and 13, which are hinged together, the lower housing 13 having a horizontally extending slot 58 in the front wall thereof. Riveted to the bottom of the housing at a raised portion 64 is a vertical post 60 having a large lower diameter 61 and a smaller upper diameter 62. A thermostat assembly 67 has an inverted U-shaped bracket 68 to transmit heat from the grid 26 to the theromstat 69. The thermostat 69 includes a bimetalic element 75 and a temperature adjusting shaft 76. A horizontally extending thermostat setting control lever 77 is welded to adjustment shaft 76. The thermostat assembly 67 is mounted on post 60 with the small diameter portion 62 entering into the cavity defined by hollow rivet 74 so that the thermostat assembly may readily slide in the vertical direction and so that it is positioned within opening 51 in tray 40 and is surrounded by flanges 52 and 53 which prevent the assembly rotating and also shield it from heating element 43. A temperature control member 80 is pivotally connected to portion 61 of post 60 and the end 86 of the member extends through slot 58 to the outside of the housing where knob 24 is attached. The member 80 has an opening 82 which is such that the member fits loosely over portion 61 of post 60. Member 80 also has a relatively large opening 83 immediately below adjustment shaft 76. Thus as knob 24 is moved in a horizontal direction control member 80 is rotated about post 60. The horizontally extending thermostat lever 77 projects through slot 85 in member 80 so that lever 77 and member 80 move simultaneously. Also, as the centre of post 60 is more distant from knob 24 than the centre of adjustment shaft 76, rotating the member 80 causes lever 77 to swing through a greater arc than member 80. A coil spring 88 is positioned on the post 60 between the thermostat 69 and the member 80 so as to bias the thermostat assembly 67 upwardly towards grid 26 and so cause the member 80 to move smoothly. A radiant heating element 43 is supported on the plurality of ceramic members 42 attached to tray 40. The tray 40 is supported by feet 44 which are attached to the bottom of the housing. The tray 40 also has two feet 48 which are fastened to the housing by screws 49. The upper tray 105 is secured to the housing by two feet 108 which are locked to the housing by screws 107. The waffle baker may be converted to a grill, or vice versa, by reversing the grids 26.
