A punch press for corrugating metallic ribbon, e.g. of stainless steel, comprises opposing die means respectively comprising yieldably extended die portions for bending and forming a first uniformed portion of the ribbon therebetween to form a first portion of a corrugation in the ribbon as one of the die portions moves yieldably to bottom on its die means and for forming a second uniformed portion of the ribbon thereby to form the remaining portion of said corrugation as the other die portion moves yieldably to bottom on its die means. A die set comprises a pair of similar die assemblies 19, 20 each comprising a forming die member 23 having one tooth 24 within which is slidably mounted a toothed flanged die member 25 loaded by a spring 38. The spring loading of the lower member 25 is greater than that of the upper member 25. In operation ribbon 27 is located, by two corrugations previously formed therein, on the lower die 25 and yieldably clamped thereto by the upper member 25. Continued lowering causes the upper member to be depressed into contact with a die support 11 and one wall of a new corrugation to be formed against the tooth 24. Further lowering depresses the lower member into contact with a support 10 to completely close the dies and form a second wall of the corrugation. The ribbon is intermittently advanced one corrugation between each pressing cycle. Air pressure means may be used in place of the springs 38. Corrugations having fluted side walls may be produced by using fluted toothed dies.

IPC: A43B23/08
Filed: 1941-05-10
Abstract: 549,297. Shoe stiffeners. BRITISH UNITED SHOE MACHINERY CO., Ltd., HILL, M. G., and COOPER, C. A. May 10, 1941, No. 6071. Class 140] In the manufacture of shoe stiffeners such as toe puffs comprising blanks of fibrous material such as swansdown cloth charged with a solution of a stiffening substance such as nitrocellulose and intended to be stored before use in a limp condition and after insertion in the shoe to undergo hardening after evaporation of the solvent the stiffening substance in solution is caused to undergo gelling at the time of manufacture of the stiffener at least at part of the stiffener to prevent seepage of the stiffening substance during storing rom one part of the stiffener to another, for example from a more heavily to'a less heavily stiffened part, by treatment effective to produce such gelling without diminution in the ratio of solvent to stiffening substance. For effecting such gelling of nitrocellulose dope the most satisfactory treatment consists in subjecting it to the action of, borax which may be dusted in powdered form on to the swansdown layer before or after the dope is applied thereto or the borax may be included in the adhesive used for uniting the swansdown layer and a crinkled paper layer on one side of 'it or the grease-proof paper layer for the other side of swansdown layer may be treated with borax solution and dried before use. Other borates or substances such as ammonia or derivatives thereof such as hexamethylene tetramine may be used as the gelling agent. Specification 487,159, [Group VII], is referred to.

Title: Method of and apparatus for varying illumination
IPC: F21V11/14
Filed: 1929-02-26
Abstract: 329,712. Hilger, Ltd., A., and Twyman, F. Feb. 26, 1929. Photometric apparatus.-Illumination of a surface is varied in a progressive manner by means of a screening device having distributed apertures and adapted to be interposed in the path of the beam of light and to be actuated so as to vary progressively the total crosssectional area of the plurality of apertures through which the light passes. In the example described the screening device comprises a disc 1 having a series of apertures 3, the diameter or the pitch of the apertures varying progressively so that a beam of light is divided into a number of beams, the total cross-sectional area of which is dependent on the part of the screen interposed in the beam. The screen may be used in conjunction with a light diffuser, e.g. in the case of a comparison source for a cube photometer, for visual spectro-photometry, for comparison of surface brightness of textiles and for photographic printing. The invention is described in connection with the latter application, and is used in a manner to ensure, a standard time of exposure for all originals or negatives. The negative to be copied or enlarged is placed in a holder 5 beneath a light diffuser 9 into which light from the source 6 enters by way of the aperture 7 in front of which is rotatable the apertured screen 1 as shown. A portion of the light passing through the negative is reflected by a transparent mirror on to a photo-electric cell A, Fig. 4. The current through the cell A due to the illumination under the voltage applied from the terminals flows through the resistance B associated with the grid of a thermionic valve C, and through the moving coil of a relay E, adapted to close either of the secondary contacts on a variation of the illumination from the predetermined standard. Upon closing either of these contacts the corresponding electromagnet of a power relay C is energized to close contacts in the circuit of the motor H, which is connected with the screen 1 and rotates it until the illumination is such that the relay E is restored to its neutral position. In place of the photo-electric cell the light may be directly viewed in comparison with a standard negative and the screens rotated until the two negatives appear of equal brightness.

Filed: 1949-03-08
Abstract: 661,909. Heat-exchange elements ; air-heating furnaces ; feedwater heaters; steam boilers and superheaters. AKTIEBOLAGET SVENSKA MASKINVERKEN. March 8, 1949 [April 28, 1948 ; Oct. 6, 1948], Nos. 6347/49 and 6348/49. Classes 64(i), 64(iii), 123(ii) and 123(iii) . Secondary heat transfer elements, intimately joined to a wall separating two passages for two fluids exchanging heat, or to one side of an air-heating wall the other side of which is heated by radiant heat, are made of high conductivity material and extend from the wall for a length not less than ten times the square root of its crosssectional area and such that the efficiency of its conductivity is at least 60 per cent, and for temperatures of over 600‹C is preferably at least 75 per cent, of theoretically complete heat transfer. The efficiency of the conductivity is defined by a formula which is a function of the dimensions and conductivity of the material of a heat transfer element and of its surface conductance, i.e. ability to transfer heat between itself and a fluid in contact with it. Surface conductance is defined for particular arrangements of elements s by formulµ which are functions of distances between and diameters of the elements, and the velocity and absolute temperature of the fluid. In a steam generator, Fig 1, of the type known under the Registered Trade Mark " La Mont," steam generating, superheating, and economizer sections S<SP>1</SP>, S<SP>2</SP>, S<SP>3</SP> in the flue 9 each comprise serpentine tubing arranged in banks. Each pair of straight lengths of tubing 12 is wound with a continuous length of wire 13 in a flattened coil. The wire is welded or brazed to the tubing. Alternate loops of the wire are deformed inwardly as shown in Fig. 5. The cross-sectional area of the wire is from 3 to 50 mm<SP>2</SP>. Other relative dimensions are given. It is stated that only one-tenth of the tubing usually required is necessary for the same amount of heat transfer. In a feedwater heater or steam superheater 17, Fig. 7, provided between a boiler 16 and chimney 18, two flat water or steam chambers 22 on opposite sides of a flue 21 are provided with secondary heat transfer elements comprising flattened coils of wire 28 supported by pairs of vertical rods 30. Dampers 32 and clean-out doors 31 are provided. In an air heater, Fig. 12, in which air flows between two walls 33, 35, the inner one of which is heated by radiant heat from a combustion zone 34. serpentine wires 40 are welded, brazed or otherwise attached to the wall 33. In a coaxial tube oil-heater in which oil flowing between tubes 43, 45 is heated by steam supplied to the tube 43 by a central tube 41, the loops 50 of serpentine wires extending along the outer surface of the tube 43 are curved as shown in Fig. 14.

March 16, 1951 [March 21, 1950; March 21, 1950; March 21, 1950; March 21, 1950]. No. 6378/51. Class 108(2) A suspension device for a road vehicle comprises fluid suspension means, regulating means for regulating fluid pressure in the suspension means, a suspended weight, and resilient means associated with the weight and actuated by vertical movement of the vehicle wheels, the regulating means being adapted to be actuated by the inertia of the weight as modified by the action of the resilient means. In the arrangement shown, a piston 12 connected to a road wheel is slidable in a compressed air cylinder 13 which is supplied through a valve 20 and pipe 14. Air is also supplied from the valve 20 to the wheel tyre 10, through a reducing valve 17. The valve 20, which is actuated by a pendulum 22 comprises a circular valve member 30 integral with the pendulum 22, and a valve seat 34 secured to a chassis member 27. A recess 44 in the member 30 is adapted to cooperate with any two of the adjacent openings 36, 37, and 38 in the seat 34, the arrangement being such that opening 36 exhausts to atmosphere, opening 37 is connected to pipe 14 and opening 38 is connected to pressure air supply line 48. A resilient strip 23 is secured to member 30 and, through a rubber bushing 24, and link 25 to the road wheel. The high pressure side of the reducing valve 17 is provided with a restriction to prevent instantaneous operation of the valve. In the arrangement described, the pendulum-operated valves on each side of the vehicle are fed from a common source and are arranged at an angle to each wheel axis whereby the vales are operative to prevent "nose-diving " and " settling," due to braking and acceleration respectively.
Patent GB-105973-A (GB)
Title: Improvements in and relating to Reversing Mechanism for Grinding and other Machines.
IPC: B24B47/04
Filed: 1916-05-04
Abstract: 105,973. Marks, E. C. R.., (Norton Grinding Co.). May 4, 1916. Driving-devices.-Relates to reversing-mechanism for grinding and other machines of the kind in which the driven member is moved through the medium of a worm and worm-wheel, the former of which is connected to a reversible-shaft, the driving-action of the shaft on the driven member being momentarily suspended at the instant of reversal. According to the invention, a driving connexion is provided between the worm and its shaft, adapted to cause the worm-wheel to move in a direction to reverse the movement of the driven member and at a speed gradually increasing from zero to substantially normal, with the worm shaft rotating at a uniform speed, and thereafter to drive the worm and worm-wheel at normal speed. In the form shown in Figs. 1 and 3, the worm 15 is loose on the shaft 16 and is provided with cams 30, 31 engaged bv arms 33, 36, or by rollers 32, 35 thereon, secured to the shaft 16. With the parts moving in the direction of the arrows, the worm 15 is driven by the engagement of the roller 32 with the projection 30<b> of the cam 30, the cams 30, 31 and the worm 15 being thereby forced to the right until the roller 35 engages the cam 31 at its narrowest portion. When the shaft 20 is reversed, the lost motion between this shaft and the shaft 16 allows the worm 15, worm-wheel 14, and the driven member 10 to come to rest, spring arms 37, 38 on the cams preventing relative displacement of the arms 33, 36 and the cams. Upon the shaft 16 moving in the reverse direction, the roller 35 moves along the wedge-shaped face of the cam 31 and forces the cams and worm axially to the left at a gradually increasing speed, during which movement the driven member 10 is started from rest and moved at a gradually increasing speed. The cams are so proportioned that when the cam 35 engages the driving side of the projection 31b, the worm-wheel 14 will be rotating at its normal speed. In a modification, lost motion is not provided between the shafts 20 and 16, but the cams are of the form shown developed in Fig. 5, the inclination decreasing from one end to an intermediate point and then constantly increasing to the other end, so that the driven member may continue its movement in the direction of previous travel for a short distance after the shaft 16 and arms 33, 36 have commenced their reverse rotation. In a further modification, the arms 33, 36 are carried by a sleeve which is mounted on the shaft 16 to rotate therewith but is capable of a limited axial movement along the shaft in opposite directions, the worm being loosely mounted on the sleeve between the arms.

A base a carries a frame b, in the lower part of which is pivoted a lever h carrying a seat l for the bomb. A spring k connected to a fixed bar d draws the lever h forward when released so as to project the bomb. The length of throw is regulated by a trigger o sliding on a graduated bar n and adapted to engage the top of the lever h when it is drawn back. The base a turns on a pivot p which fits in a hole in a base-board. The base-board is divided into squares lettered and numbered as shown in Fig. 3, over which a graduated arm s fixed to the base a moves as the projector is turned. The target is divided into squares corresponding to those on the base-board, but reversely numbered so that the position of the arm determines the correct direction of throw. The graduations on the arm s correspond with those on the bar n, and indicate the length of throw. The target may be provided with pictorial representations of a battle-field, and may be fitted with toy trees, soldiers, &c. The bombs preferably consist of bags loosely filled with sand or small shot. The apparatus may be combined with a scout's wagon, in which case the shaft or pole takes the place of the bar d.

A vertically disposed machine set for a pumpedstorage power plant comprises a motor-generator, a pump-turbine and an auxiliary turbine for starting the machine set for pump operation. The auxiliary turbine is of the radial outward flow reaction type, receiving its driving water through a conduit 5 from the main pressure pipe of the machine set. The auxiliary turbine is adjusted to the synchronous speed of the motor-generator by governing means controlling an inlet valve 6 or adjustable inlet guide vanes (not shown) in place of the stationary guide vanes 7. In addition the auxiliary turbine may be used for braking the machine set during turbine operation of the pump-turbine. During normal running of the machine set the auxiliary turbine is isolated by valves 6, 9, and drained and ventilated by valves 10, 11 to reduce losses, a passage 12 and non-return valve 13 providing the necessary communication between the upper and lower chambers of the turbine. The auxiliary turbine may be arranged beneath or between the pump-turbine and motor-generator. The hydraulic lift on the runner of the auxiliary turbine relieves the load on the thrust bearing of the machine set and thereby helps in overcoming the initial break-away torque at starting.
