Title: Improvements in apparatus for drying webs of fabric
IPC: F26B13/04
Filed: 1932-09-09
Abstract: 398,344. Feeding webs. WENZEL, E., 17, Wettinerstrasse, Aue, Erzgebirge, Germany. Sept. 9, 1932, No. 25195. [Class 100 (i).] In apparatus for drying webs of fabric looped over the transverse bars of a travelling chain, an automatic detector arranged in the vicinity of a loop or loops is responsive to changes in the length of the loop or loops and controls mechanism for regulating the relation between the rates of intake and delivery, so that the change in the length of the loop, due for example to a change in the amount of shrinkage during drying, causes a corresponding change in the speed of delivery. The feeler itself is preferably adjustable to suit a selected normal length of loop. In the form shown, an endless chain 7 in the drying chamber 4 is driven by sprocket wheels 6. A delivery roller 22 is driven from an electromotor 29 through means including gears 30, while the feed roller 19 is driven through shaft 17 from another electromotor. The bars 26 of the chain 7 are rotated by a chain 23 engaging with sprocket wheels 27, this chain 23 being driven through gearing from the shaft of the roller 19, so that the bars 26 are rotated at a rate depending on the rate of revolution of the roller 19. Near the last loop of fabric is a vertically adjustable bracket 31 having a bearing for a shaft 32 carrying a series of fingers 33. On the shaft 32 is also a contact arm 34 carrying an electric contact 35. The shaft is loaded and tends to rock the arm towards a stationary contact 37, but the weight of loops of normal length holds the arm in a central position. If the loops become longer, the shaft is thereby rotated to bring contact 35 towards another stationary contact 36, to close a circuit whereby the motor 29 is accelerated ; if the amount of shrinkage increases, the parts 35 and 37 contact, and the speed of the motor is reduced. Instead of the electric feeler a mechanical, hydraulic, or pneumatic feeler may be used.

Title: Improvements in or relating to counting tubes
IPC: H01J31/04
Filed: 1957-08-09
Abstract: 857,339. Electron beam apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 9, 1957 [Aug. 14, 1956], No. 25205/57. Class 39(1). A counting tube has a collecting electrode consisting of a slightly conducting layer 9, Fig. 1, preferably coated on the inside of bulb 1, on which conducting strips 6, 7 are applied and joined by straps 8. The purpose of layer 9 is to remove electrons which do not strike straps 8 which are of a material whose electrical conductivity increases sharply on electron bombardment and which may advantageously be luminescent in order to indicate the beam position. The ribbon-shaped beam 5 is generated by cathode 2 and deflecting plates 3, 4, and strikes the collecting electrode assembly. One or more grids (not shown) may be placed between plates 3, 4 and the collecting electrode to obtain sharp definition of the beam and to withold secondary electrons from the collecting electrode. Strip 7 is connected to cathode 2 whilst strip 6 and plate 3 are connected to a positive voltage supply via resistor 10. The beam is held in position (partially) on (one) of straps 8, since if it moves to the right, the resistance of this strap decreases sharply, thus increasing the current flowing between 6 and 7 and causing a voltage drop across 10 which in turn lowers the potential of plate 3 and the beam is deflected to the left, whereas the reverse is the case if the beam moves to the left. A positive pulse applied to plate 4 moves the beam to the next strap. The beam may be moved from the last strap lock to the first by known means. Strips 6, 7 may be of silver, applied by vaporisation or a paste, and straps 8 which may be of zinc sulphide or cadmium sulphide may be applied likewise. The slightly conductive layer 9 may be a very thin metal layer or a layer of tin oxide. In a further embodiment in which the conducting strips are placed one behind the other and are separated by a layer of a material whose conductivity increases sharply on electron impact, aluminium straps 14, Fig. 2, cover straps 13, for example of cadmium sulphide, arranged on a conducting layer 12 of tin oxide coated on the tube wall 11. Straps 14 are connected to strip 15 which is in turn connected to a positive-voltage supply via a resistor, whilst 12 is at a higher potential. Electrons striking 14 are able to penetrate and produce a rapid increase in the current flowing between 12 and 14, the action of the tube being substantially as described above. This embodiment combines a simple electrode arrangement with high amplification, the latter permitting the use of a rod-shaped beam.

Title: Improvements in or relating to vulcanised closed cell cellular expanded rubbery articles
Filed: 1952-10-15
Abstract: 744,165. Making sheets of cellular expanded rubber. RUBATEX PRODUCTS, Inc. Oct. 15, 1952 [Aug. 30, 1952], No. 25836/52. Classes 70 and 87 (2). A mix of vulcanizable rubbery material, vulcanizing agents and a finely-dispersed substance which on heating generates a gas is put into a mould expandable in one dimension only; the mix is heated to a temperature sufficient to generate said gas and to partly or fully cure the material; the internally-generated gas is permitted to expand the mould and the material to a limited extent in said one dimension; and the expanded material is cooled or allowed to cool whilst it is confined against further expansion. The drawings show a rectangular mould coinprising two recessed aluminium plates 10, 11 into which the rubbery mix is filled. Figs. 3 and 4 show the mould before the mix has been expanded and Fig. 3a after it has been expanded. The longer sides of the mould plates have projecting ledges 26, 27 which lie between U-shaped clamping bars 30 forming two sides of the frame shown in Fig. 6. The other two sides of the frame are constituted by bars 40, 41. To hold the filled mould closed temporarily before it is placed between heated ram-operated platens P, locks 43 are mounted on bars 40, 41 and engage recesses 45 in the mould ends. When the mould has been positioned between the platens the locks are released, the mould is heated, the ram pressure on the platens is released and the mould halves are allowed to expand from the Fig. 3 position to the Fig. 3a position to a limit determined by the bars 30. At least partial curing is effected before the ram pressure is released; if the cure is incomplete before this release it is completed after expansion but before cooling. The mould is removed from the press, cooled in air or water and opened. Shoe soles may thus be made. Side plates 20 prevent escape.of material from the expanded mould. Specification 737,485 is referred to.
Patent GB-258700-A (GB)
IPC: H01G5/06
Abstract: 258,700. Bell, L. H. Bainbridge-, and Radio Communication Co., Ltd. July 11, 1925. Condensers are made with a scale reading directly proportional to the square root of the sum of capacity of the condenser and a fixed specified capacity, the object being to make the scale read the actual wavelength of the circuit, which wavelength is not zero at zero scale reading but depends on the condensers minimum capacity, and any external capacity which may be in the circuit. To this end, a suitable specified value of external capacity is chosen and the vanes are so shaped that variation of the angular relation between the fixed and moving vanes is proportional to the thereby-produced variation in the square root of the total capacity and therefore to the wavelength of the circuit containing the condenser and external capacity. Then a curve is drawn representing as abscissµ the angular variations and as ordinates the corresponding wavelengths, which curve puts the axis of ordinates at a point corresponding to the minimum, plus the external, capacity and is produced to cut the axis of abscissµ at a point representing zero wavelength and capacity. This point is taken as the zero of the scale and the point of maximum adjustment as the maximum, and the scale is evenly divided, but only marked over the actual range of adjustment. Figures are given of the shape of six moving plates forming part of a 0.0003 microfarad condenser, the radius of the plate being given for each 10 degrees of adjustment.

[Class 110 (iii).] In a power plant comprising a triple expansion engine exhausting to a turbine the working fluid from the engine is reheated before entering the turbine. The Figure shows a steam plant in which a boiler C supplies steam to two reciprocating engines A1, A2 and in each unit the exhaust steam passes from the L.P. cylinder h to the reheater k, around which circulate the boiler waste gases, before passing to a changeover valve o, which may operate automatically, and being directed either to a forward r or reverse section s of a turbine. A pipe t then leads the exhaust to a condenser. The turbine drives a power shaft B through triple reduction gearing, and the reciprocating engine drives shaft B through single reduction gearing. In an alternative arrangement the steam may be reheated electrically, and current may be generated for this purpose by a dynamo driven by the turbine. The turbine may be unidirectional, the change-over valve leading steam either to the turbine or to the condenser. The dynamo driven by the turbine may supply power to auxiliary machinery. Mechanical gearing may be replaced by electrical or hydraulic gearing. The steam from the boiler may be initially superheated and re-heated from stages of expansion in the cylinders.
