Abstract: 399,502. Nonconducting coverings for heat. MUNTERS, C. G., 75, Linnegatan, Stockholm. Feb. 29, 1932, No. 13851/33. Convention date, March 3, 1931. Divided on 402,726. [Class 64 (ii).] Heat-insulating material comprises a hermetically sealed element divided into layers or cells, and containing gas having a lower heat conductivity than air, and composed of molecules, at least one of the atoms of which is heavier than oxygen ; gaseous compounds of halogens or sulphur such as sulphur dioxide or hexafluoride and carbon bisulphide may be used. The element may be in the form of a plate with outer walls f of metal enclosing a cellular or powdered material g, such as silicious earth, glass wool, or powdered hard rubber, and gas at atmospheric pressure or less. The edges h of the plates may be corrugated to interengage, and are formed of a nonconductor such as celluloid or ebonite. In a modification, the element consists of parallel plates of aluminium foil and outer walls of thicker sheets ; the spaces between the foils inter-communicate by holes. Gas is blown through openings in the edges which are then sealed. In another form, the element comprises a large number of gastight cells formed in a nonconducting material such as celluloid. Specification 399,503 is referred to.

Title: Production of triggering pulses during variable-duration periodic movement sequences
IPC: F02P3/045
Filed: 1975-04-07
Abstract: 1465234 Ignition systems; timing ignition SIEMENS AG 7 April 1975 [24 April 1974] 14116/75 Heading F1B [Also in Division G4] Apparatus for producing a triggering pulse at a predetermined time before a predetermined event in the cycle of a variable duration periodic movement, e.g. before top dead centre in an I.C. engine, comprises means for determining the period of the cycle, means for detecting the event and a counter started at the event to count clockpulses for a period equal to the difference between the period of the cycle and the predetermined time. The period may be measured by an A/D converter 2, the result being stored as a binary word P at 3. A store 4 holds the predetermined time W and 5 an initial count N. A calculator 6 calculates a value A = N Œ (P-W) depending on whether 7 is a downcounter or a up-counter. A comparator 8 determines when the counter reaches the initial count N, after starting counting at the value A at the event, and issues the triggering pulse. The counter may alternatively count from the initial value to the calculated value, Fig. 2 (not shown). The predetermined time may be made to vary in dependence on the period; when the triggering pulse is used as an ignition pulse in the I.C. engine this may be arranged to ensure that the engine is always fired at the most efficient, least polluting time before t.d.c. The calculating device 6 may be replaced by a read only memory Fig. 3, 4 (not shown) whose output values are already adjusted to vary the predetermined time. The circuit may be modified to provide constant energy supply to the ignition coil. In Fig. 6, an extra comparator 60 detects a count N 1  somewhat before N to set a bi-stable 61 which controls current to the coil. The comparator 8 then resets the bi-stable cutting off the current to generate the ignition spark.

IPC: F22B29/06
Filed: 1958-05-02
Abstract: 847,022. Critical pressure boilers; reheaters. COMBUSTION ENGINEERING Inc. May 2, 1958, No. 14127/58. Classes 123(2) and 123(3) A forced-flow, once-through boiler, operating at supercritical pressure comprises a furnace 10 tangentially fired through burners 12 and lined with generating tubes 16 whence steam flows serially through radiant and convection superheaters 18, 20 to an outlet 22 to a turbine. Steam from the turbine to be reheated enters a header 32 and passes through a reheater convection section 26 to a header 38 from which it flows through pipes 50 to a series of headers 44 each supplying a platen 40 or 42 of nested radiantly heated reheater tubes, the platens being. spaced across the width of the upper part of the furnace 10. The outlets of all the platens are connected to a header 45 whence a pipe 47 returns the reheated steam to the turbine. To avoid the possibility of some of the reheater platens becoming overheated due to the non-uniformity of temperatures and gas flow distribution throughout the cross-sectional area of the furnace the steam flow to those platens located in the lower temperature regions is restricted, with correspondingly increased flow in the hotter platens, so that the temperature of the steam leaving each of the platens is generally uniform. The flow restricting means consists of orifices 54 which are provided at the inlets of the pipes 50 supplying steam to the platens in the cooler furnace regions.

Abstract: 791,660. Ear protectors. NATIONAL RESEARCH COUNCIL. May 18, 1955 [May 20, 1954], No. 14350/55. Class 81 (2). An ear protector comprises a rigid non- porous cup to fit over the ear, a cushion supported by the rim of the cup and means for pressing the cushion into engagement with the head around the ear, the cushion having a high spring constant so that it does not vibrate when subjected to sound and being in the form of a non-expansible, non-porous, flexible, endless tube which is partially filled with non-gaseous fluid material having a viscosity below about 1m poises but is substantially free of gas and has no unfilled space. A continuous flexible inexpansible tube 20 is secured to a rigid cup 18 and has a filling tube 21 for a liquid having a viscosity below 1m poises, e.g. cane sugar syrup. The cup 18 is secured to a threaded stub 14 by a ball joint 17, the threaded stub 14 having a wing nut 15 to secure the cup 18 to a resilient head frame 11 having a central sponge rubber head pad 12. The frame 11 presses the cup 18 and the filled tube 20 against the head so that the exposed edges of the tube 20 assume a semicircular shape in cross-section. Seams, wires or other metal structures may be placed so that they extend completely round the inner and outer exposed portions of the tube 20 and so that, when the cup 18 is pressed against the tube 20 and the head, they resist deformation more than the tube wall and form a line of discontinuity in the curvature of the tube wall. The tube 20 is filled so that it is dilated to more than a quarter of its full cross-section but less than its full cross-section. The tube 20 is made of a material, e.g. plasticised polyvinyl chloride resin, having a high dynamic Young's modulus of about 5 Î 10<3> p.s.i., a high internal resistance and a thickness of 0.005 to 0.01 inch. The width of the rim 19 of the cup 18 is substantially the same as the radial width of the filled tube when the latter is pressed against the head.

Patent GB-733789-A (GB)
Title: Improvements in or relating to photographic type-composing machines
IPC: B41B21/04
Filed: 1952-06-09
Abstract: 733,789. Photographic type -composing. HIGONNET, R. A. E., and MOYROUD; L. M. June 9, 1953 [June 9, 1952], No. 14519/52. Class 98 (1). [Also in Group XL (b)] In a photographic type-composing machine of the kind in which a character to be reproduced on a light-sensitive surface is projected on to the surface by illuminating the particular character in a font carried on a matrix, e.g. a drum or disc, a number of shutters each having light transmitting code elements are provided the shutters being displaced in accordance with a code representing the character and means are provided for scanning the shutters while the matrix positions each character in turn in the projection position so that when the light beam intercepts a set of code elements in register the character in the projection position is illuminated. As shown, light from source 1 is brought to a narrow beam and passes through the edge of the character-bearing matrix which is a rotating disc 3. The beam then passes into the centre of a hollow rotating shaft 27 and is reflected by mirrors, 7, 8,. 9 and 10, and finally 'focused by a lens 11 on to a photo -electric cell 12. The horizontal beam of light passing between mirrors 8, 9 is thus traversed around a cylindrical surface and is arranged to be intercepted by the periphery of code discs 19-26. A development of the edge of these coded discs is shown in Fig. 3. In the position shown, no clear light path can be found through the edge of the discs. Displacement of disc 26, however, gives a clear path along the line 82, and displacements of combinations of discs by means of solenoids 33 (Fig. 2) give other light paths corresponding to a particular character on the matrix. The matrix 3 and shaft 27 are rotated synchronously by gears 14, transparent marks 31 being provided on the matrix so that the light beam can only pass through the matrix and the code disc when the character is aligned with a projection lamp 43. When the photo-cell 12 receives light which has passed through an aligned set of discs a condenser 44 discharges through lamp 43 to project the character in the projection position on to sensitive surface 41. A rotating half-plate 17 cuts off the light beam during alternate revolutions of the matrix so as to allow time for advancement of strip 41. In a modification (Fig. 4, not shown) the discs are replaced by apertured cylinders arranged concentrically within each other around the axis of the rotating shaft, selection of a particular character being effected by axial movement of selected cylinders. The light beam passing the coding cylinders may be used to print the character directly. Specifications 669,556, [Group XL (b)], 685,310, 691,761, 691,762, 691,763, 691, 910 and 733,788 are referred to.

Title: Improvements in swash plate or slant type reciproco-rotary mechanisms
IPC: F16H23/10
Filed: 1924-06-16
Abstract: 218,637. Crankless Engines, Ltd., (formerly Crankless Engines (Aus.) Proprietary, Ltd.) July 4, 1923, [Convention date]. Swash-plate linkages for driving air-compressors or for other apparatus in which rotary motion is to be converted into reciprocating motion, or vice versa, and of the type described in Specifications 118,098, 172,972, and 179,156, [Class 102 (i), Pumps &c.]. The swash-plate and parts moving therewith are arranged to move axially in opposition to the movements of the pistons. In the form shown in Figs. 1 and 2, the swash-plate 1 is secured to the driving-shaft 2, which may be coupled by a sliding coupling 27 to a power shaft and is connected by a loose coupling 17 to a rotary valve 10 which controls the inlet and exhaust ports of air-compression cylinders 5 spaced at about 90‹. Each piston carries slipper-plates 8, 8<a> such as described in the prior Specifications engaging opposite sides of the plate 1, or any form of engagement between the pistons and plate 1 may be used. Additional steeper parallel surfaces 19, 20 are provided on the plate 1 and are engaged by slipper-plates 21, 24 on adjustable abutments 23, 25 on the casing, or the abutment 25 may be spring-supported. As the plate 1 rotates, it moves axially in opposition to the movement of the pistons. The positions of the cylinders and the inclination of the surfaces 19, 20 are determined by formulae based upon the weights of the plate 1, shaft 2, and parts moving therewith and of the pistons &c., respectively, the object being so to balance the moving parts as to reduce vibration &c. A valve, sliding but not rotating with the shaft 2, may replace the rotary valve 10, and the shaft 2 may be so arranged as not to reciprocate with the plate 1. By axial adjustment of the abutments 23, 25 the clearance of the pistons in their cylinders may be varied. In the form shown in Fig. 7, the abutment 23 is carried in a part 30 formed with a rack for adjustment by a pinion 31. The part 30 slides in guides 23<a>; if the guides are parallel to the face 19, the piston clearance alone can be varied, but if the guides and face are not parallel, movement of the part 30 adjusts both the clearance and the strokes of the pistons. Springs may be arranged in the cylinders to bear on the pistons so as to ensure contact of the plate 1 with the slipper-plates 21, or a retaining-plate of the kind described in Specification 172,972 may be used. As shown in Fig. 9, the plate 1 is made adjustable in inclination to vary the piston stroke by fitting it with opposing pins 41, 42 bearing through slipper-plates in guide channels 47, 48, which are adjustable by screwed rods 49, 50 controlled by toothed gearing 53, 54, 55. The face 18 of the plate engages an abutment 23 as before, and the plate, shaft, and channels reciprocate against the action of a spring 36. As shown in Fig. 14, cylinders 5 spaced 180‹ may be used, the pistons 6 being rigidly connected by a yoke 60 and slipper-plates 8, 8a being provided on one only of the pistons for engaging the plate 1.
