Title: Improvements in solid fuel fired boilers for use with any kind of solid fuel
IPC: F23J1/00
Filed: 1955-05-19
Abstract: 788,187. Solid fuel-fired furnaces. BAILLON, M. L. C. E. May 19, 1953 [May 21, 1954], No. 14448/55. Class 51 (1). In a solid fuel-fired boiler comprising a stationary hearth 1 and a hopper 2, the lower portion of the latter defines, with the hearth floor, a combustion air inlet slit 4 and a combustion gas outlet slit 5. A water-cooled baffle 14 is disposed behind slit 5 and defines, with the hearth floor, a clinker removal slit 6, the height of which is smaller than that of the slit 5. The boiler has lateral water spaces, a secondary combustion chamber 9 and an ash-box 10 into which clinker is pushed by a ram 11. A suction fan creates a negative pressure in the boiler and additional air admission means are two rows of openings 7, 8, through the hearth and rows 12, 13 of tubes in the front wall of the lower portion of the hopper. The baffle 14 comprises a box, the two ends of which are in communication with the lateral water spaces whilst the top is connected to an upper water space of the boiler body. The hopper 2 has small openings 84 such that the negative pressure draws a current of air down through the hopper entraining on its way any volatile substances therein. The stroke of the hydraulically-operated ram 11 and the intervals of operation thereof are such that the clinker height at the entrance to ash-box 10 is less than the height of slit 6. This prevents clinker jam under baffle 14. The upper part of chamber 9 has gas outlet orifices 15. Air openings 7, 8 have air flow adjusting means whilst a removable cover 77 is disposed in front of tubes 12, 13 and forms a wall of a chamber which is open at its bottom to allow the entry of air feeding the tubes. The hopper holes 84 are in communication with this chamber through piping 184.

Title: Improvements in two-stroke cycle internal combustion engines
IPC: F02B25/14
Filed: 1922-05-23
Abstract: 180,679. Klee, J. May 24, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Two - stroke - cycle engines. - Air admitted through the port m is compressed on the instroke in the pump chamber i, and combustible mixture is compressed in the crank case. At the end of the in-stroke the air, which has been heated by contact with the piston, is transferred through the port p to the chamber b and some mixes with any combustible mixture trapped in the chamber. Towards the end of the out-stroke, the compressed mixture from the crank case drives before it the air and mixture from the chamber into the power cylinder, the exhaust passing out through the port n. At the commencement of the in-stroke, as the pump displacement is greater than that of the power piston, part of the charge is drawn back into the chamber b, the pressure in the chamber b being equalized with that in the crank case. The pump may serve a number of power cylinders and in this case may be constructed independently of the power cylinder.

Title: Improvements in or relating to a power assisted control device for an operation in a typewriter
IPC: B41J23/06
Filed: 1966-04-01
Abstract: 1,137,152. Typewriters. PAILLARD S.A., 1 April, 1966 [9 April, 1965], No. 14554/66. Heading B6F. The power action to operate e.g. the tabulator mechanism of a typewriter, comprises a locking mechanism which holds a control lever 14, operating the tabulator mechanism, in operative position until the operating key is released. When the tabulation key 1 is depressed, a lever 3 pivots about 7 to move a link 28 in direction A, and through the agency of a spring 29 move a locking lever 26 with nose piece 30 into locking position with the control lever 14. Lever 14 is operated at the same time from the key 1, by means of an element 2, pin 10, lever 11, pawl 18, a pawl 19 and pawl 17 which, when released by the pawl 19 engages a continuously rotating snatch roll 33. Pawl 17 is pivotally mounted on the control lever 14 which is thus moved by the angle #. Pawl 17 is restored by a more powerful spring 23 between the arm 14 and pawl 18 and the engagement of surfaces 37, 36. The control lever 14 is held by its nose 31 in the nose piece 30 until the key 1 is released whereupon the spring 8, which is stronger than a spring 29, releases the locking lever 26. The control lever 14 is connected via rod 16, lever 15 to the tabulator mechanism operating lever 32 to control disengagement of the typewriter carriage, escapement, and tabulator stop.

Abstract: 1,214,910. 910. Programme control of machine tools. G.E. OFFENSTADT. March 27, 1968 [April 6, 1967], No.14787/68. Heading G3N. [Also in Division B3] A machine tool has an operating unit cyclically movable, relative to a support for a workpiece, between an inoperative and an operative position, which carries a means for detecting the position of a tool member supported on the workpiece connected to a programme control means for controlling a means for moving the operating unit. As shown, Fig.1, a stationary punching table 1 supports a die 4 on which rests a workpiece 3 and a punch 5 which is driven vertically by a pressing plate 2, sequenced to move forwardly until above the punch and then downwardly to effect a punching operation. The plate 2 bears a light source 6 and a photo-cell, between which passes a light beam which is interrupted by the front edge 5a of the punch 5 and remains interrupted until the beam passes the rear edge. In a control system, Fig.4, signals, indicative of the position of the punch with respect to the light beam between the source 6 and the photo-cell 8, are fed to a programme device and remote control panel 9 and to a memory device 10. The device 9 controls the supply to a motor 11 driving a pump 12 for the hydraulic system of the press and the supply to the light source 6; relays 13a, 13b provide for remote control of the machine by an operator. When the plate is moved horizontally the time during which the beam between source 6 and photo-cell 8 is cut off is recorded by a memory 10 and the plate 2 is stopped, with or without a time delay, when, by continued movement of plate 2, the light beam is again received by the photocell 8. The information stored in the memory 10 is utilized to control, through the panel 9, the return motion of the plate 2. It is stated that the light source and cell are vertically movable relative to the plate 2, to avoid damage during the vertical movement of the plate.

Title: Resinous products and processes for their production
IPC: C09F1/00
Filed: 1940-10-09
Abstract: 546,384. Cellulose and other carbohydrate derivatives ; resinous condensation products. POLYXOR CHEMICAL CO., Inc. Oct. 9, 1940, No. 15058. Convention date, Oct. 24, 1939. [Classes 2 (ii) and 2 (iii)] Resinous material is obtained by mixing a polymerized carbohydrate and one or more of those resin acids, such as abietic and pimaric acid and their isomers, that are contained in tall oil or wood resin, or a mixture of such acids and fatty acids found in tall oil or wood resin and heating the mixture to induce reaction between the constituents. The polymerized carbohydrate may be a cellulosic substance or a cellulose conversion product, pentosan, lignin, starch, or dextrin. The acidic constituent may be in the form of a free acid or a lactone or a polymerized product. The acid mav be mixed with other substances provided that they do not have any deleterious effect on the product, particularly as regards its dielectrical strength and electrical resistance. Tall oil or wood resin may be used as the acid constituent. The proportions of the carbohydrate and acid may be varied. The mixture may be heated to 300‹ C. or higher at atmospheric pressure. As the reaction proceeds, the mass becomes molten. To ensure even distribution of the heat, vessels of high thermal conductivity may be used and pieces of metal may be placed inside the vessels. Metal ribs or projections on the inner surfaces of the vessels may be provided. The products obtained are soluble in chlorinated hydrocarbons, benzol, pinene, or related solvents. They may be used for making varnishes or coatings. They are resistant to water and chemicals such as nitric acid and caustic soda and insoluble in mineral oils. They may be applied as coatings to metal or ceramic materials. Further polymerization of the initial product may be effected by further heating. The product may be moulded and then further polymerized. In an example, sulphite wood-pulp is heated with tall oil at 300‹ C. After cooling, the mass is a sticky liquid. The non-resinous products are removed by mixing the mass with methanol containing a small amount of water and then allowing the non-resinous solution to separate. The residue is a dark resinous material, soluble in carbon tetrachloride or pinene. Ground wood or waste paper may be used as cellulosic material. The tall oil may be heated before it is mixed with the paper or other material. If desired, the components may be heated while being mixed, e.g. the vapours of the acid may be passed through the carbohydrate material. The Specification as open to inspection under Sect. 91 comprises also the use, as acidic component, of any high boiling aliphatic or aromatic acid which may be obtained by extraction from wood by solvents or alkaline solutions. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in variable ratio gearing
IPC: G01F15/02
Filed: 1938-05-20
Abstract: 498,800. Variable - speed ratchet gearing. HEJDUK, F., and NEUMANN, J. May 20, 1938, No. 15119. Convention date, May 20, 1937. Addition to 464,214. [Classes 80 (ii) and 80 (iii)] Accurately controllable variable-ratio gearing, more particularly for use in the drive of counting mechanism 18 of a liquid flow meter, comprises a main roller free-wheel clutch 6, which always forms a direct connection between a disc 3 keyed to the driving shaft 2, and a driven element 4, which latter is also common with the driven element of a secondary roller free-wheel clutch 9, the driving disc 8 of which is adapted to be periodically advanced in relation to the driving shaft 2 so as to increase the speed of the driven shaft during such advance. In the form shown in Figs. 1 and 3, such advance is effected by a cam 11 on the disc 3 and having an arm 10, adapted to strike an adjustable fixed stop 13 so as to turn the cam 11, which acts on a flat face 121 on the disc 8, thereby advancing the latter through an arc 19 in advance of the disc 3. After the arm 10 passes the stop 13, a spring 15 returns the disc 8 to its initial position relative to the disc 3, with the flat face of the cam 11 lying on the flat face 12<1> on the disc 8. The free-wheels 6, 9 permit this return without affecting the advance in motion gained by the driven element 4. The adjustable stop 13 may be replaced by a circular track of adjustable eccentricity, engaged by a roller on the arm 10. In the form shown in Figs. 5 and 6, the periodic advance of the driving disc 8<1> of the secondary free-wheel 9<1> is obtained by a bevel toothed sector 25 pivoted on a pin 26 on the driving disc 31 of the main free-wheel 61 and engaging a similar toothed sector 24 on the disc 8<1>. The sector 25 has an arm carrying a roller 27 which tracks a stationary inclined ring 28, pivoted about an axis 29. A torsion spring 15<1> biasses the discs 4<1>, 8<1> to an initial position. The inclination of the ring 28 determines the degree of advance periodically given to the driven element 4<1>, and is automatically varied by a thermally responsive bellows 30, so as to provide an automatic correction for temperature variation of the liquid being measured.

Title: Improvements in bed and cylinder printing machines
IPC: B41F3/02
Filed: 1921-06-01
Abstract: 183,651. McInroy, T. June 1, 1921. Cylinder machines.-A cylinder machine of the kind in which the reciprocating bed gears with a freely-mounted wheel on the impression cylinder fitted with pawls which transmit motion to the cylinder under the control of engaging and disengaging mechanism, as described in Specification 136,284, is arranged so that the cylinder rotates continuously by providing a second wheel, which is geared to the bed by a separate transmission gear, and is so constructed that the second wheel takes up the drive as the first wheel is disengaged. The two driving-wheels are arranged at the opposite sides of the cylinder, and in addition to the cam-operated disengaging levers 10, 11, similar to the one described in the Specification referred to above, a second pair 22, 23, are also employed. The application of the invention to the tworevolution press shown in Fig. 3 is such that the impression cylinder A makes a revolution and a quarter while the forme moves from the position F to the position F'. The cylinder is then driven by its second drive at a reduced speed, and rotates for three-quarters of a revolution while the bed returns, and the printed sheet is delivered. The cylinder is raised as the bed returns. If desired, the cylinder may rotate at equal speeds during successive movements of the bed. In a onerevolution machine, part of the impression cylinder is cut away, and in this case the printing movement of the bed may take place while the cylinder rotates through either a half or any fractional part of a revolution, the return being effected during the remaining period. In a twocolour machine in which two printing-surfaces are used, the three revolutions of the cylinder for one multi-colour impression may be so arranged that the outward motion of the bed occupies a period of one revolution and three-quarters, and the return motion the remainder. In this machine the levers 22, 23 are formed as one cam-shaped member pivoted at its centre. In a perfecting machine, the two impression cylinders are geared together, and each rotate continuously in the same direction.
