Title: New or improved method of and apparatus for admitting secondary combustion air into the combustion chambers of furnaces
IPC: F23L9/00
Filed: 1932-12-01
Abstract: 402,934. Supplying air to furnaces. PETERSEN, K., Buddinge, Denmark. Dec. 1, 1932, No. 34071. [Class 51 (i).] The regulation of the amount of secondary air admitted to the combustion chamber a, Fig. 1, of a furnace fired with solid fuel on a grate is effected by a complete shutting off or a complete opening of a greater or smaller number of secondary air inlet openings d<1>, d<2>, d', d<4> which are fed with air from a common blower or the like so proportioned or driven that the velocity of admission of the air is approximately independent of the number of openings in operation or increases slightly for a smaller number of openings. A modified form of inlet member comprises a nozzle formed by two pivoted curved tongues k, Fig. 3, which are either swung together to close the inlet or are separated by a fixed distance. They may be adjusted in non-symmetrical position to admit the air in an oblique direction. In another form, Fig. 2 an air inlet is divided by partitions into compartments f<1>, f<2>, f<3> and provided with a regulating flap h serving not only for completely closing the inlet but also for stepwise opening. Such an inlet may be supplemented by a rotatable nozzle, Fig. 5, having coaxial outlet channels n<1>, n2, n<3> provided with blinders such as q2 which give a pulsating outflow of air. The nozzle may be rotated by a small turbine wheel s or may be independently driven. The air supply may also be shifted to different points of introduction. Means may be provided for closing some or all of the secondary air inlet openings in sequence at predetermined intervals of time during the distilling of the fuel. A shaft 7, Fig. 7, is rotated from a motor 1 through a friction drive 3, 4, a worm 5, worm wheel 6 loosely mounted on the shaft and a second friction drive 9, 10 and carries a number of cams 11, a disc 12 with a cam finger 13 and a pinion 14. By adjustment of the wheel 3 the shaft may be made to rotate once during successive firings. Each of the cams 11 has three concentric circular portions of different radii and serves to operate, as shown in Fig. 8, the controlling flap of an inlet member of the kind shown in Fig. 2. At the end of a firing period the cam finger 13 by engaging a roller 15 serves to move the tooth 20 of a pawl 19 to a position above a slide 32 having a notch 33 and also to ring a bell 40. On the opening of the fire door 28, the pawl is moved through lever mechanism to engage in the notch 33. On closing the door the pawl moves the slide to the right, as seen in Fig. 9, causing a wedge 31 to lift a rack 29 and through the pinion 14 turn the shaft 7 back to its starting position. The pawl is subsequently released by a roller 38 and the slide returned by a spring 36.

Title: Improvements in or relating to straight bar knitting machines
Inventor: BROWN LEONARD
IPC: D04B11/00
Filed: 1958-10-28
Abstract: 930,068. Knitting. WILLIAM COTTON Ltd. Oct. 22, 1959 [Oct. 28, 1958], No. 34415/58. Class 74 (2). Cable stitch effects are produced on a straight-bar machine by providing two adjacent groups of loop transfer points 1b, 1c mounted in a common block 3 carried by the narrowing head of the machine. The two groups are capable of being independently operated so that after the narrowing head has been operated to cause all of the points to transfer in the same direction the associated needle loops to adjacent needles, as shown in Fig. 3, the points of one group 1b are raised to disengage their loops whilst the other group 1c remain in engagement with the needles and retain their loops, Fig. 4. The narrowing head is now given a second movement whereby the points 1c move in the opposite direction and transfer their loops to the needles originally holding the loops transferred by the points 1b such that the transferred loops of each group now cross each other as shown in Fig. 5. As shown in Fig. 7, each group of points is operated through linkage from a cam 28, 37 and the shogging of the block 3 to effect the cross transfer of loops is effected by a cam 12 operated through pawl- and-ratchet mechanism driven from main camshaft 20.

Title: Improvements in or relating to push button mechanisms for tuning radio receivers
IPC: H03J5/12
Filed: 1938-11-26
Abstract: 521,817. Push-button mechanism. METCALFE, C., and PARRISH, H. J. Nov. 26, 1938, No. 34448. [Class 37] In a mechanically-operated push-button receiver the manual tuning means is automatically declutched while a push-button is depressed. Depression of a push-button 1 causes its associated arm 2 to contact with a pivoted vane 3 running longitudinally across the chassis and thus rotate a disc 5 fixed on the trunnions carrying the vane 3. An arm 5a on the disc 5 is connected to lever and link mechanism 6, 7 the end of the lever 7 being adjustably pivoted on a support 9. The rotor axis 16 of the tuning condensers is rotated manually by a knob 15 through friction gearing comprising a disc 12 the edge of which is gripped between the shaft 13 carrying the knob 15 and a collar 10 mounted on the reduced end 13a of the shaft 13 and pressed against the disc 12 by a spring 11. The collar 10 is connected to the lever 7 so that on rotation of the vane 3 the lever mechanism 7, 8 moves away the collar 10 from the disc 12 thus breaking the friction drive. Press-button mechanism. Depression of a push-button 1 causes a cam 17 adjustably mounted thereon to contact with a pivoted plate 18 which extends longitudinally along the chassis and is provided with slots through which the arms 2 pass. An end plate 20 is formed rigidly with the plate 18 and is pivoted to levers 22, 23, 25 connected to the rotor axis 16. Depression of a push-button thus rotates the rotor element of the condenser through by an amount depending on the inclination of the pivoted plate 18 to the corresponding faces of the cam 17 which is adjusted according to the tuning position required. Rotation of the axis 16 is transferred by means of an endless chain on the pulley 27 to another pulley carrying a pointer moving across an indicator scale. In a modified form of the apparatus (Figs. 3 and 4, not shown) the push-buttons are arranged vertically and the friction drive for manual tuning takes the form of a driving wheel making frictional contact on the inner surface of a flanged disc attached on the rotor shaft, disconnection of the drive being obtained by levers which move the driving wheel upwardly against the tension of a spring.

Title: Apparatus for cutting cheese wheels into segments
Inventor: BROOKS JOHN LUKE
IPC: B26D3/24
Filed: 1959-10-13
Abstract: 957,169. Cheese cutting apparatus. J. W. FLOWER & CO. (ENGINEERS) Ltd. Oct. 13, 1960 [Oct. 13, 1959], No. 34659/59. Heading A4C. In apparatus for cutting cheeses and the like into smaller pieces, taut cutter wires and a thrust plate are provided with means for displacing them towards each other relatively, the wires crossing one another along an axis parallel with the direction of relative displacement of the wires and plate so that a cheese placed between the wires and the thrust plate can be cut into pieces of wedge form, and one end of each wire is nearer to the thrust plate than its other end, the nearer ends being at different distances from the thrust plate, whereby successive wires progressively enter the cheese during a cutting operation. The apparatus comprises a table 1 and a circular thrust plate 2 which is vertically reciprocable by a hydraulic ram and cylinder 3. Coaxially above the thrust plate is a ring 5, having a number of spring loaded wires 6 extending diametrically across it. The ring is supported above the thrust plate by four posts 9a, 9b, 9c, 9d. The six wires shown are arranged in groups of three so that the lower group commences to cut the cheese into 60 degrees wedges, and fully enter the cheese before the upper group cuts the 60 degrees wedges into 30 degrees wedges. The thrust plate consists of 30 degrees segments 12 on a plate 13 fixed to the ram, the segments being arranged to leave slots 14 to register with the wires 6, and the depth of the segments being such as to allow the wires to pass completely below the surface of the plate. A cheese to be cut is slid on to the thrust plate and centred in relation to the ring 5 by means of pivoted jaws 19, which are connected by a series of levers (20 to 25) so that movement of any one of the jaws towards the centre of the plate by means of a hand lever 26 causes an equal and similar movement in the other two. After centring, the jaws are retracted and the ram is caused to rise until the top of the thrust plate has passed through the top of the ring 5, then the ram is lowered and the cut cheese removed. Fig. 6 shows an attachment for cutting the core out of a cheese during the cutting operation. A vertical tube 30 is carried by arms 32 mounted on upward extensions 34 of posts 9b and 9d. The tube is slotted as at 37 to enable it to clear the wires 6. Within the tube is an ejector block 38 which is reciprocable by means of levers 40, 42 and 45, and is slotted to receive the wires 6.
