Title: Glass-metal seal method and apparatus
IPC: H01J5/26
Filed: 1957-06-06
Abstract: 830,433. Glass-to-metal seals. CORNING GLASS WORKS. June 6, 1957 [June 13, 1956], No. 18081/57. Class 36. Skirted metal hollow inserts 63 are sealed into the wall 62 of a glass article such as a television tube panel by locally heating the insert and the region of the glass into which it is to be inserted until the glass is workable, mechanically engaging the insert and pressing the skirt into the glass wall whilst continuing to apply heat, and releasing mechanical engagement and pressure from the insert whilst the glass is still workable so that the pressure of the entrapped air within the hollow insert repositions it slightly to improve the sealing contour. An apparatus for sealing such inserts into a walled panel has a base plate 18 carrying posts 14 containing electric heating elements with carbon buttons 19 on which the under surface of the panel rests and which heat the glass. A central post 20 carries a four-armed spider 22 with laterally sliding members 23 terminating in branched arms 25 and 26, each of which is provided with electric heating elements and carbon buttons 31 which abut the inner wall surface of the panel. The sliding members are moved radially in unison, to locate the panel, by means of a roller cam arrangement 39 and 40 driven through gearing 45 to 50. Heater units 60 each comprise a pocket to revive the metal insert 63, the pocket being surrounded by flame outlets disposed to direct the flame on to the insert skirt and on to the wall of the panel when the assembly approaches it, the gas supply arrangements being described in the Specification. The heater units are slidable in radial channels on the base-plate by operation of a lever 65 secured to flange 56 of the hub 55, the resultant rotation of the latter being translated by the links 57 to radial movement of the burner slide 57. A cover 100 is provided to enclose the panel during preheating and subsequent annealing and cooling operations.

Title: Method of making grape sugar
IPC: C13K1/10
Filed: 1923-07-12
Abstract: 227,140. Marks, E. C. R., (Corn Products Refining Co.). July 12, 1923. Crystallizing.-Relates to processes of producing crystalline glucose consisting almost entirely of hydrated or anhydrous crystals as may be required. For this purpose the concentrated liquor is cooled down to a temperature suitable to the production of crystals of the type required and seeded with crystals of that type; the liquor is then agitated while crystallization takes place and separated from the crystals in a centrifugal. For producing hydrated crystals the liquor is concentrated to about 40‹ BaumÚ and crystallization takes place at between 95 and 105‹ F. ; for producing anhydrous crystals the liquor is concentrated to from 38-45‹ BaumÚ, and for average operations to about 41‹ BaumÚ, and crystallized at a temperature of 110-135‹ C. according to the density. When a considerable quantity of anhydrous crystals has been produced the temperature may be allowed to fall lower. A system of operations for producing sugar in two or more stages is described. The liquor, after concentration in a vacuum pan C and crystallization in a jacketed chamber D provided with an agitator, is removed from the sugar in a hydro-extractor E, in which the sugar is then washed in the ordinary way. The mother liquor is passed to a filter F, again concentrated in a vacuum pan H, and passed to a crystallizer J and a hydro-extractor K. The mother liquor from the hydro-extractor K is passed through a filter M to a vacuum pan O, a crystallizer P, and a hydro-extractor Q.

Title: Improvements in hydraulic transmission of power
IPC: F16H39/32
Filed: 1945-07-16
Abstract: 596,038. Hydraulic transmission of power ; fluid-pressure servomotor-control systems. SEGSWOBTH, R S. July 16, 1945, No. 18149. [Classes 69 (ii) and 135] A hydraulic power transmission comprises a fluid-tight casing in which a driven shaft 8 and a driving shaft 9 have vane type rotors 10 and 13 respectively mounted thereon, these rotors being enclosed by cylinders 14 and 15 respectively. The cylinders have inlet ports 18, 20 and outlet ports 19, 21, and are attached to lateral extensions 16 slidably mounted on guides 17. Each cylinder is attached to the piston rod 26 of a piston 27 working in a cylinder 24. The cylinder 24 has ports 25, 35, and the piston has ports 28, 30, 31, 32. A piston valve 38 slidably mounted in the bore of the cylinder head has ports 39, 40 spaced as shown. The outward end of the piston valve 38 of the driven rotor carries a roller 44 which engages a U- shaped slot 46 in a slidably-mounted plate 45 operated by a control rod 48, movement of which causes the cylinder 14 to move relative to the axis of the rotor 10 thereby altering the eccentricity of the rotor with respect to the cylinder thus changing the output of the rotor. The piston valve 38 of the driving rotor has a sliding plate 49 with a U-shaped slot 51 in a reverse position to slot 46, and plates 45 and 49 are connected by a rod 50. Due to the arrangement of the slots, initial movement of the control rod 48 produces increased output by the driven rotor 10 to a maximum value whilst the stroke of the driving rotor 13 remains at a maximum followed by a reduction of the stroke of the driving rotor 13 and hence increased speed. Means are provided for separately reversing the direction of rotation of the driven and driving rotors.

Title: Improvements relating to screw propellers
IPC: B63H1/12
Filed: 1929-06-14
Abstract: 340,000. Kristofersen, E. L. June 14, 1929. Drawings to Specification. Screw propellers. - In screw propellers with combined variable radial and axial pitch the pitch of the pressure surface at the leading edge varies from tip to root in accordance with the varying average axial velocity of the inflow water in the annular zones about the centre of the propeller. Single screw propellers have a decreasing pitch and outboard twin propellers have an increasing pitch and in combination the pitch is altered axially across the blade until the pitch at the following edge is approximately constant but where there is a decrease or increase in pitch this is dependent upon the thickness or thinness of the axial sections. The angle of deflection of the water between the leading and following edges increases from the tip to the root in accordance with a hyperbolic law. For laying out such a screw surface the template rotates about the centre outside the propeller axis and the following edge coincides with a line through the moulding centre and with a line connecting this centre and the propeller centre.

Title: Rigid Rotor Helicopter and Method of Flying Same
IPC: B64C27/14
Filed: 1967-04-21
Abstract: 1,188,345. Rigid rotor helicopters. UNITED AIRCRAFT CORP. 21 April, 1967 [29 June, 1966], No. 18409/67. Headings B7G and B7W. A helicopter 10 has two counter-rotating coaxial rigid rotors 24, 26 each having at least three blades, arranged so that when each blade of one rotor passes over the tail portion of the fuselage 12, a blade of the other rotor passes in the opposite direction; the pitch of the blades being varied cyclically during forward flight by speed responsive means so that the centre of lift for each rotor moves away from the rotor axis 28, remaining within the rotor disc area, the resulting roll moments for the two rotors cancelling the movements of the centres of lift being controlled to give an optimum lift-to-drag ratio for the blades. The optimum ratio is stated to be corresponding to the following formulµ P = 47 Á; where 0 # Á # 0À8 P = 37.5 e <SP>{0.7</SP> <SP>(0.8-Á)}</SP> where Á > 0À8 P = resultant rotor lift vector offset as a percentage of rotor radius Á = advance ratio e = base of the natural logarithms. The helicopter rotors 24, 26 may be driven by two power plants 30, and there may be a further power plant 33 to assist forward flight. A linkage to vary the rotor blade pitch is also described, Figs. 2 and 3 (not shown). It is stated that the controlled cyclical variation of rotor-blade pitch of this invention gives a greater lift during forward flight, and a greater speed range than that obtained with blades capable of flapping and lagging. Control mechanism.-The blade pitch of the rotors 24, 26 are varied by swash plate mechanisms controlled by rods 310, 312, 314 (upper rotor) 316, 318, 320 (lower rotor). The collective pitch is varied either: of both rotors together by pivoting handle 254 about fixed pivot 258 thereby moving bell-crank 262 (which is bias to a centre position by springs 286, 287) lever 266 about pivot 270, levers 282, 298 and 284, 300 about pivots 306, 308 thereby moving rods 310, 316 and with them rods 312, 314, 318, 320; or of both rotors differentially (to produce yaw movement) by moving pedals 322, 324 about axis 326, thereby rotating wheel 274 about pivot 276 moving levers 282 and 284 and rods 310, 316 differentially. The swash plates of the blade pitch control mechanism are tilted together in a pitching movement by pivoting control column 200 about pivot 204 thereby pivoting bell cranks 250, 252 about pivots 294, 296 to move rods 312, 318. The swash plates can be tilted in a rolling movement, either: together by turning wheel 208 about pivot 206, thereby rocking lever 222 about pivot 226 to move rods 314 and 320; or differentially by causing servomotor 346 to move cable 334 thereby rotating wheel 230 and moving rods 314 and 320, the servomotor 346 being operated either by pilot-operated switch 341, or by computer 342 in response to an airspeed signal from pilot tube 338, the computer causing the servomotor to have an output corresponding to the value of P in the formulµ above.

Title: Improvements in or relating to Inking Mechanism for Printing Presses.
IPC: B41F31/12
Filed: 1916-12-22
Abstract: 107,725. Goss Printing Press Co., (Goss Printing Press Co.). Dec. 22, 1916. Inking -apparatus. - Relates to apparatus of the kind in which the inkfeeding devices are operated to feed more ink relatively to the speed of the press when the press is running at low speed, and consists in controlling the increase and decrease of the speed or drive of the ink-feed mechanism by the speed of the press itself. As shown in Fig. 1, the ink is supplied from a fountain roller 13 by a messenger roller 12 to the ink cylinder 11, and the fountain roller is driven intermittently by ratchet gear 15, 16, 17 from a shaft 20 driven in timed relation with the press, a rod 18 connecting the crank-disk 19 to the pawl lever 16. In order to reduce the effective engagement of the pawl 15 with the ratchet wheel 17, and consequently the amount of each movement of the fountain roller 13, as the speed of the press increases, a governor 27 is provided on a shaft 25 driven by the press. The sliding part 26 of this governor is connected to an arm 22 of a pivoted shield 21 over which the pawl runs during part of its movement when the press is running at the higher speeds, the governor acting to move the shield, so as to reduce the number of teeth the pawl effectively engages as the speed of the press increases. In the arrangement shown in Fig. 4, the fountain roller 13 is geared by worm gear 29 to a ratchet wheel 32 driven by pawls 35, 36 on arms 33, 34 operated by rods 37, 38 from a crankdisk 39 rotating in timed relation to the press. The rods 37, 38 are connected to a crank-pin p on a lever 41 pivoted at q to the disk 39 and carrying a weight 42 which acts by centrifugal force against the pull of the spring 43 to move the pin p nearer to the shaft 40 as the speed increases, thereby reducing the radius of the crank-pin and the movement of the pawl levers 33, 34.

Title: Electromagnetically-operated valve
IPC: F16K31/06
Filed: 1977-05-03
Abstract: The solenoid valve, which is designed as a three-way valve, contains a solenoid plunger (10) which interacts with a coil (5) and has continuous longitudinal grooves (19, 21) on the circumference, of which two, diametrically opposite longitudinal grooves (19), serve to accommodate return springs (20) which are supported at the bottom by a supporting ring (14). Two further, diametrically opposite longitudinal grooves (21) serve as flow channels. Since it is possible to form these longitudinal grooves (19, 21) integrally during the production of the solenoid plunger, there is no need for subsequent machining and, as a result, manufacture is simpler and cheaper. <IMAGE>
