Title: Improvements in and relating to the wrapping of cakes or other articles
IPC: B65B11/02
Filed: 1938-03-26
Abstract: 515,089. Wrapping-machines. WEBBER, W. W., and FULLERS, Ltd. March 26, 1938, No. 9374. [Class 94 (i)]. A machine for wrapping-up fragile articles of irregular shape comprises a feed table 5 along which a web of cellulosic or other wrapping material is drawn by jaws, suction grippers or intermittently operating feed rolls. The articles are placed on the wrapper web, marks on the table indicating the spacing, and are drawn towards the folding apparatus by the web. When the leading article has arrived over the folding table 6, the web is severed, and arms 7 engage and raise the edges of the wrapper to bring them together over the top of the article. The arms terminate in perforated rubber &c, pads 9 connected to suction devices through flexible hoses 10 to control the wrapper during the folding movement. The movement is obtained by a lazy-tong device 11 connected to a sliding block 12. The upstanding edges are now gripped and rolled up by pairs of jaws or spring blades 14 advanced into position by reciprocating rods 15 and opened against a spring 18 by the rounded end 17 of a rod 16. The blades may be rotated by rack and pinion or chain means, and may be mounted to move downwards during the rotation. The rolling may be stopped so as to leave a space between the article and the wrapper, if a loose . wrapping is desired. In another method of operation, the edges of the wrapper are brought into and rolled into the ultimate horizontal position which the fold is to occupy. Slack being left at the sides of the article. A fold retaining device comprising a suction head 19 is lowered to prevent the fold from unfolding, while end folders 23 descend and turn down the open-ended parts of the wrapper, and blades 28 mounted for rotary movement, turn in the side wings of the resulting fold. Folders 29 next turn down the folds beneath the article, in which position they may be secured by adhesive, heat-sealing or the like. A pusher 31 moves the completed packet on to a delivery belt 32, an inclined surface 33 controlling the folded ends. The pusher is normally below the surface of the table, and is raised into engaging position by a cam surface 34. The delivery belt, which may be of rubber, may be bodily raised to cause it to engage the folds. In order to prevent unnecessary contact between the article and the wrapper, air may be blown into the packet during folding, through perforations in the wrapper that coincide with nozzles in the table. Each nozzle may be surrounded by an annular suction nozzle to keep the wrapper in place.

Title: Process for the extraction of zinc
IPC: C22B19/04
Filed: 1927-04-06
Abstract: 294,127. Roitzheim, A., and Remy, W. April 6, 1927. Distilling zinc.-In a process for extracting zinc in an externally and internally heated vertical muffle, any zinc oxide formed is separated from the zinc vapours before the latter are condensed. The muffle b is charged at a and air is introduced at the bottom. The zinc and zinc oxide vapours are passed through a condenser c comprising plates e through apertures in which a mass of coke progresses. The zinc oxide condenses on the coke and is removed by the conveyer g and the zinc vapour is condensed in the condenser d. The approximate temperatures at various points are as shown in the drawing. Alternatively, the temperatures may be so controlled that the zinc oxide condenses in the upper part of the muffle and is returned as the charge progresses to the hotter, lower part of the muffle, the condenser c being dispensed with.

Abstract: 598,915. Radiation detectors ; discharge apparatus. BENDIX AVIATION CORPORATION. April 16, 1945, No. 9516. Convention date, March 13, 1944. [Classes 39 (i) and 40 (iii)] Apparatus responsive to heat and light radiation comprises a vacuum tube 10 having at one end a sealed window of rock salt 11 and containing adjacent the window 11 a conical holder 13 for a substance 14 such as carbonized vegetable fibres in the form of a fine fluff so that in response to radiant energy waves transmitted through window 11 the substance 14 is activated to release stored gases which flow through vents in the holder 13 to the opposite end of the tube 10 and there become ionized by collision with electrons flowing between a filament 15 and a surrounding grid 18 to thus produce a current flow at an adjacent plate 21. connected in series with a current limiting resistance 23 to a battery 28 so that it is at negative potential with respect to the grid 18. The current impulses from plate 21 are fed to an amplifier 26 and thence to an instrument 27 which is therefore actuated to a degree dependent on the intensity of heat or light radiation impinging on substance 14. A condenser 25 prevents response to slow variations resulting from changes in ambient temperature. In a modification, Fig. 2 (not shown), a glass window formed integrally with the tube 10 is substituted for the rock salt window 11 and the apparatus thus rendered of greater sensitivity to radiant energy within the range 0.5 to 2 microns.

IPC: B60K17/10
Filed: 1960-03-18
Abstract: 913,740. Throttle control; hydraulic transmissions. LUCAS (INDUSTRIES) Ltd., JOSEPH. March 20, 1961 [March 18, 1960], No. 9610/60. Classes 79(2) and 79(5). A motor vehicle hydraulic transmission wherein an engine-driven pump supplying a fluid-activated motor for driving a wheel or wheels of the vehicle comprises means to prevent wastage of engine power, especially at low speeds, due to undue throttle openings, in which a throttle actuating member is spring-loaded in a direction to follow the movements of a driver operable member whilst the latter is moved in a direction to open the engine throttle, stop means being provided to limit the opening of the engine throttle to accord with the speed of the vehicle. As shown, the vehicle engine 1 drives a pump 2 supplying, in closedcircuit, a motor 3 which drives the vehicle wheels 4 through a differential 5. A throttle control member 6 is connected to a link - 7 through which slides a rod 10 connected to the driveroperable pedal 11. A spring 9 biases the member 6 towards an open position and a stronger spring 12 operates in the converse direction on pedal 11. A stop member 13, which limits the movement of link 7 in a throttle opening direction, is connected to a rod 14 of a piston 15 in a cylinder 16. The piston 15 is biased in a throttle closing direction by a spring 17 which is located in the cylinder 16 on the side of the piston 15 which is connected on the downstream side of an orifice 18 to a pipe line supplied by a pump 19 driven at a speed proportional to the speed of the vehicle, the other end of the cylinder being connected to the upstream side of the orifice. When the vehicle is at rest, the stop 13 will permit only a small throttle opening, but as the speed of the vehicle increases, the pressure drop across the orifice 18 increases and the piston 15 moves in a direction to permit greater throttle openings until a position is reached whereby the stop 13 is moved away from the lever 7 and the throttle setting is dependent only on the position of pedal 11. A reservoir 19a is connected to the pipeline on the downstream side of the restricted orifice.

Filed: 1951-04-25
Abstract: 681,073. Coke-oven doors. KOPPERS CO., Inc. April 25, 1951, No. 9665/51. Class 55 (i) [Also in Group XXVI] The resilience of the steel sealing member 54 of a coke oven door is enhanced by making it of channel shape which permits the sealing-edge 58 to move through a relatively large distance without permanent distortion of the member. The member 54 is secured by nuts 65, in position on the door margins and around the retainers 40 for the plug 41 and the leveller door opening, packing 66 sealing the member 54 to the face of the door. The edge 58 is held against the face of the door frame 14 by spring- pressed plungers 72 which are spaced around the door, the inward movement of the door being positively limited by adjustable stops 80. The four sides of the member 54 are each made from a rolled channel section, the web being thinner than the flanges which latter each form the upstanding part 57 carrying the sealing-edge 58. The web is cut along the longitudinal middle line and each half is bent down to form the vertical flexing part 61 of the finished side, and then inwardly to form the horizontal fixing part 62. The four sides so made are welded together to conform with the shape of the door, the corners of the member 54 being rounded off. The door is secured by pivoted latch bars 42 and latches 16, and is provided with a pivoted, latched, screwpressed door for the leveller opening.

Title: A device for limiting the aerodynamic efforts on aircraft
IPC: B64C1/00
Filed: 1937-04-05
Abstract: 477,506. Fluid-pressure servomotorcontrol systems. MERCIER, P. E. April 5, 1937, Nos. 9677, 9678, and 9679. Convention dates, April 10, 1936, June 13, 1936, and Feb. 18, 1937. [Class 135] [Also in Group XXXIII] The aerodynamic forces on the wings of an aircraft are limited by automatically varying the lift of the wings in accordance with the deformation of the wing under the load. As shown diagrammatically in Figs. 1 and 2, a comparatively inextensible element 1 is secured at one end 2 to the wing structure and operates at its other end 3 a control member of a servomotor 18 according to the wing deflection resulting from, for example, a gust of wind or a flattening-out movement of the aeroplane. The servomotor 18 actuates a wing flap 6 to modify the aerodynamic force on the wing. When the gust has passed, or the flattening- out movement completed, the point 3 and therefore the flap 6 is returned to the normal position. The comparatively inextensible element may comprise a single bar or wire, the movement of which is amplified by a lever-system, or a series of bars or wires connected together to give a summation of the movements of each member, and acts on a floating lever connected between the actuating member of the servomotor and its pilot valve or control member. By arranging an elastic connection with damping means between the element 1 and the control member of the servomotor the control of the flap 6 and the limitation of the aerodynamic forces can be made to depend upon the rate of deformation of the wing. The device described may be applied to each wing individually or to both wings simultaneously and may be utilized, apart from the limitation of the aerodynamic forces, for the servo-operation of the normal camber-flaps for landing and taking off, or even banking, by the provision of an additional manual control as in Figs. 10 and 14 in which the inextensible elements, in this case two wires, are connected at 115 and 119 to a lever 120 pivoted at 121, on which lever is pivoted another lever 153, one end of which is connected to a rocker 156 for operating valves 160, 161 controlling the pressure fluid to the servomotor 19 for operating the wing flaps through a lever 109, and the other end of which is connected through a link 152 to a follow-up lever 145 which is actuated by a rocker connection 133 from the piston rod 132 of the servomotor (shown in Fig. 10 only), to a rod 135, Fig. 14, of a movement-reducing device 136, a rod 137 of which is connected at 181 to the lever 145. The end 180 of the lever 145 is normally fixed but can be moved by manual operation of a screw-and-nut device 148, 149 to operate the valves 160, 161 for controlling the servomotor 19 as required. Locking devices 140 and 171 are provided for the levers 109 and 120 respectively, which are normally kept out of operation by the pressure of the operating fluid for the servomotor but are adapted on failure of the pressure to lock these levers to prevent the flaps from fluttering.
