Title: Improvements in or relating to resilient members having parallel terminal surfaces
IPC: F16F1/02
Filed: 1946-04-30
Abstract: 611,449. Helical springs. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. April 30,1946, No. 12992. Convention date, May 2, 1945. [Class 108 (iii)] In a resilient member of the kind comprising a number of helicallywound elements arranged coaxially in mutually inclined positions between two terminal planes, at least three elements are wound clockwise and an equal number are wound anti-clockwise, each clockwise-wound element being joined to an anti-clockwise-wound element and vice versa in each terminal plane, the joints in each terminal plane being evenly distributed around the axis of the member. In the form shown in Fig. 2, which is suitable for eliminating the axial play of a shaft, three anti-clockwisewound elements 20, 21, 22, of spring plate are secured respectively at their lower extremities to the extremities of similar but clockwisewound elements 25, 23, 24 and to a common base plate 26. In a second construction, Fig. 1, (not shown), a spring having greater length than its diameter is formed from three anti-clockwise-wound wire elements arranged coaxially but mutually angularly spaced by 120 degrees. Three similarly-disposed springs of smaller diameter and clockwise-wound, are arranged coaxially with the first set of elements. Each of the second set of elements has its extremities looped round to join the respective extremities of a corresponding element of the first set. The three loops so formed at each end lie in a plane normal to the axis of the spring, which may be constituted by a single continuous wire. The invention may be applied to establishing electrical contact between parts located on each side of the resilient member.

Title: Application of liquid to a surface
IPC: C08J7/00
Filed: 1975-04-01
Abstract: 1530462 Photographic processes NATIONAL RESEARCH DEVELOPMENT CORP 30 March 1976 [1 April 1975] 13253/75 Heading G2X Method and apparatus for photographically processing sheet material 18 as it is fed past opposite walls of a vessel 10a, wherein liquid is directed to the surface of material 18 facing the vessel 10a and suction is applied within vessel 10a to cause air-flow between material 18 and at least one of the walls and the air-flow strips the liquid from the surface of material 18 and conveys it to vessel 10a, so that material 18 leaves vessel 10a substantially dry. A second vessel 10b is placed symmetrically with respect to vessel 10a so that material 18 is fed between the vessels by two sets of feedrollers 2, 3 and 5, 6. Material 18 may pass progressively between further pairs of vessels 11a, 11b, 12a, 12b, 13a, 13b. Vessel 10a has two walls 19a, 19b joined at the top and mounted between end-plates (20, 21), Fig.2, (not shown), to form an outer chamber 19. The base of vessel 10a comprises strips 25-28 extending between plates (20, 21). An inner housing 24 is fixed to strips 26, 27. Liquid, e.g. developer is pumped by pump 33 from a reservoir 35 to pipe 32 to inner housing 24 and its counterpart in vessel 10b. Developer is thus applied to both sides of material 18. Suction is produced in chamber 19 and its counterpart by a pipe 36 leading to a space above the liquid in reservoir 35, which space is connected to a vacuum chamber 38. The liquid spreads in both directions along material 18, and is stripped off by the suction between strips 25, 26 and 27, 28. After development the material may pass to vessels 11a, 11b, 12a, 12b, 13a, 13b, of slightly different construction, which are connected to the vacuum chamber 38 and to reservoirs 53, 61, 65 containing respectively fixer, washing and fixer eliminating liquid, and washing liquid (water). The material emerges substantially dry and may be placed on a table 4, or may go to a further drier. The photographic material is fed in by a table 1, which is then closed by a lid 70 so that the machine may subsequently operate in full light.

Title: Improvements in carburetters for internal combustion engines
IPC: F02M3/02
Filed: 1952-05-26
Abstract: 722,739. Carburetters. SOLEX. May 26, 1952 [June 21, 1951], No. 13328/52. Class 7 (3). A carburetter including an idling device capable of feeding the engine with an air and fuel mixture when the throttle valve is in its idling position, i.e. in its position of maximum closing or very close to this position and including a device adapted by modifying the section of at least one air or fuel or mixture passage of the idling device to reduce or cut off the fuel delivery of the idling device when the degree of opening of the throttle valve is greater than that which corresponds to idling, embodies means adapted to delay the re-establishment of the normal fuel delivery of the idling device after the throttle valve has been brought back from an open position to its idling position. In Fig. 1, a well 8 supplied with fuel from the fuel passage 5 leading to a main nozzle 4 supplies idling fuel to a passage 10 to which air is admitted through an orifice 11 and which leads to at least one orifice for instance to orifices 12, 13 (adjustable by screw 14 Fig. 2) adjacent the edge of the throttle valve. A valve 22 operated by a diaphragm 18 exposed to the suction on the engine side of the throttle valve is employed to close or partly close the mixture passage 10 when the suction is below a predetermined value and to open it with some lag when the throttle valve is brought back to its idling position. The desired lag is produced by use of a restricted passage or orifice 20 through which the suction is transmitted to the diaphragm. A delay in feeding fuel through the idling jet is obtained. In Fig. 2 a valve 25 is employed to control the air supply to the passage 10. The valve 25 is operated by a diaphragm 26 subjected to the suction on the engine side of the throttle valve. A by-pass passage 27 around the valve 25 is employed. A restricted orifice 20 is inserted in the conduit 19. The temporary cutting off of the idling jet facilitates starting when the engine is warm.

Title: Improvements in or relating to the manufacture of hydrocyanic acid
IPC: C01C3/14
Filed: 1932-05-12
Abstract: In the manufacture of hydrocyanic acid, stabilizing concentrations of sulphur dioxide are maintained in the reacting system and retained in the hydrocyanic acid formed.  The process may be carried out by acting with an acid on a mixture comprising a metal cyanide and a metal sulphite.  The sulphur dioxide may also be introduced as gas evaporated from liquid stored in cylinders.  Any process for the manufacture of hydrocyanic acid may be modified in this way, for example the dehydration of foramide to form hydrocyanic acid and water.  According to an example an aqueous solution containing sodium cyanide and sulphite was continuously reacted with sulphuric acid solution by mixing p  streams of the reactants.  The hydrocyanic acid vapour contained sulphur dioxide which was not removed in the subsequent purifying, dehydrating and condensing stages, stable liquid hydrocyanic acid being produced.  Specification 10442/95, [Class 1, Acids, alkalies, &c.], is referred to.

Title: Wave-guides
IPC: H01P3/02
Filed: 1975-04-03
Abstract: 1537271 Waveguides NATIONAL RESEARCH DEVELOPMENT CORP 29 March 1976 [3 April 1975] 13691/75 Heading H1W Structures for support of the dipole wavepropagation mode comprise a hollow conductor and one or more internal conductors or arrays of conductors. The dipole mode is fully described in Specification 1,392,452 and is designated EH or HE where H and E signify that there are electric and magnetic components in the direction of propagation. Such waves are able to propagate in the constructions of the invention at frequencies below the cut-off frequency for the dominant mode in the hollow member. In the simplest construction (Fig. 1a) a longitudinal conductor 11 lies adjacent one wall 12 of a hollow rectangular conductor 10. The conductor and wall support the semi-dipole mode (vectors E) which is one half of a full dipole mode symmetrically bisected by the wall 12 which behaves as an electromagnetic mirror. The opposite wall 13 is positioned a sufficient distance from the conductor 11 to avoid interference with the evanescent wave existing between the conductor and the wall 13. The single conductor may be replaced by an array 19 of parallel conductors (Fig. 2b) which may take the form of ribbons supported by a dielectric sheet. A further array 18 may be symmetrically arranged with respect to the first array 19; such a structure will propagate two semi dipole modes. Alternatively, the full dipole mode may be propagated in the space between the arrays 18, 19. The semi dipole mode may be launched by means of a probe extending through the wall 12 in the direction of the vector E. Alternatively the conductor 11 may constitute an extension of the central conductor of an input (or output) co-axial line having an outer conductor attached to an end wall of the waveguide (Figs. 3,4, not shown). In the launching arrangement of Fig. 6, conductor 27 forms a common (transverse) end wall of input waveguide 30 and the semi dipole mode propagating structure 11, 12 (see also Fig. 1a). A slit 28 is arranged in the wall 27 parallel and adjacent to the wall 12.
