Title: Hydrodynamic retarder
IPC: F16D57/04
Filed: 1975-05-19
Abstract: 1516211 Hydrodynamic brakes LABAVIA SGE 19 May 1975 [4 June 1974] 21353/75 Addition to 1466723 Heading F2S The mounting of the hydrodynamic brake for a shaft 43 described in Application No. 21223/74 is modified to allow replacement of the endless belt 50 on pulley 23 without removal or axial displacement of the brake. As shown, three mounting lugs 30 are provided on casing 25 and teeth 46 with intervening recesses 47 are formed on the stator 6 of the brake. Co-operating surfaces 48, 49 on the lugs and teeth ensure that the brake remains centred with respect to shaft 43 in any angular position of the stator; the circumferential extent of each lug is greater than that of any recess so that the lugs are never out of contact with the teeth. Belt replacement is effected by disconnecting the fluid supply connection to the brake; removing bolts 32; placing the belt around the stator; threading the belt between the teeth in such a way that belt sections pass radially inwardly through the recesses 47 immediately adjacent and on the same side (in a rotational sense) of each lug; rotating the stator until those lengths are on the opposite sides of the lugs; disengaging the belt from the teeth by moving it into the space around the pulley; and returning the stator to its original position. The stator may be rotated before the belt is threaded, the belt being moved around the pulley after restoration of the original stator position. The number and circumferential extent of the teeth and recesses are specified with particular reference to Fig. 2 (not shown). The terminal faces of the lugs may be in different radial planes and at different radial distances from the axis of shaft 43.

Title: Improvements in airships
IPC: B64B1/62
Filed: 1929-07-17
Abstract: 336,950. Watkins, A. H., (Slate Aircraft Corporation). July 17, 1929. Aerostats.-An airship of the type described in Specification 302,413 having a compensation bag 5 positioned at the centre of buoyancy has two sources of fuel supply controlled by valves situated in an engine compartment 3. The compensation bag comprises an inverted dome-shaped cover 5 within which is a flexible gas bag 39 formed by upper and lower diaphragms 8, 10, Fig. 3, which contains a power gas lighter than air, such as natural gas, coal gas, or water gas. The space 40 between the cover 5 and diaphragm 10 communicates with the atmosphere through a valved pipe 11, and the compartment 39 supplies fuel gas to engines 57 through a pipe 19, a valve 44, a pulsating bag 43 and a manifold 46. Liquefied gas is stored in a tank 50 which may be sealed to allow an internal pressure to build up by evaporation of the liquid. The evaporated gas may be fed to the main supply line to the engine, via a starting motor 49, any excess of gas over that required for the engines serving to refill the compartment 39 driving out air from the space 40. The tank 50 is surrounded by a suitable insulating-jacket 51 which is provided with vents 52, 53 and a. fan 54 for circulating the hydrogen in the envelope round the tank to increase the rate of evaporation. Control of the buoyancy of the ship is effected by exhausting the gas supply in the compensation bag and admitting air or by replenishing the bag from the liquid gas supply and driving the air out, or by closing valve 44 and allowing the compensation bag to function automatically.

Filed: 1970-05-07
Abstract: 1312704 Analysis OSTERREICHISCHE STUDIENGESELLSCHAFT FUR ATOMENERGIE GmbH 7 May 1970 [12 May 1969] 22102/70 Heading G1A In a method of analysing a material or constituent of a process by bombarding the material or constituent 3 with a beam 5 of photons and monitoring the scattered radiation 7, the bombarding photon beam is produced by interacting a beam of relativistically accelerated elementary particles with the photons of a laser beam so that the particles transfer energy to the photons to produce the bombarding photon beam. In determining the composition of a melt 3 in a steel converter 1 the energy of the initial elementary particle beam is chosen so that the bombarding beam 5 comprises mono-energetic y-rays. The energy of this beam 5 is preferably kept below the nuclear threshold so that the scattered radiation 7 comprises only y-radiation and not neutrons and/or protons. A pulse height analyser is used in the circuit of the detector 8 to make a quantitative analysis of element(s) in the melt 3. The detector circuit also contains an analogue (14) and a digital (12) computer which control a process control unit (13) which in turn controls the O 2  supply rate and pressure to the furnace and the position of the burner lance 2 Fig. 2 (not shown). The detector 8 may be a scintillation or semiconductor detector, e.g. Ge (Li), Si (Li), in Sb, CdTe, Na I or plastic. The bombarding beam 5 may be applied intermittently. The method may be applied to biological processes e.g. determination of iron in the blood, sodium in fingernails, iodine in the thyroid glands, and fluorine in teeth.

Title: New or improved materials and moulded bodies of high electrical and thermal conductivity and high chemical resistance and a process for the manufacture thereof
IPC: C04B35/532
Filed: 1959-06-30
Abstract: A conducting material, heat and pressure moulded under conditions preventing or inhibiting lateral spreading of the moulded substance and having a specific resistance below 0,1 Ohm. cm. comprises an aggregate of graphite particles, the majority of which have a smaller overall anisotropy than a single crystal of graphite, which aggregate has been compressed under substantially solvent-free conditions, and as binder for the aggregate 5 to 30% wt. of a heat and chemical resistant thermoplastic resin which softens over a range of at least 2 DEG C., the anisotropy of the macro-structure of the total material corresponding to a preferential crystallographic orientation of the crystallites of not more than 30%, the degree of orientation in the material being defined as the distribution of 002 planes in all possible angular positions.  Suitable graphite particles are derived from waste graphite powder.  Resins specified are polymers of halo-hydrocarbons, e.g. polyvinyl chloride, polytrifluoromonochloroethylene and polytetrafluoroethylene.  The material may be used in the construction of chemical apparatus or as an electrode.  Composite moulded bodies are claimed wherein the material of the invention is used to form an electrode which is integrally moulded with a holder constituted by a material comprising the same components but differing in resin content, size and size distribution of graphite particles and shape of graphite particles and degree of compression, e.g. that described and claimed in Specification 928,352.  Graphs (not shown) are provided showing how the graphite particle size distribution, moulding temperature and pressure, and resin content affect the resistivity, porosity and strength of the product.  Nearly all the points plotted correspond with products not satisfying the resistivity requirement of Claim 1 but it is stated that by correlating the graphs combinations of factors providing the products claimed can be predicted. Specifications 653,367 and 729,321 also are referred to.

Title: Differential optical polarisation detectors
IPC: G01N21/21
Filed: 1973-05-11
Abstract: 1472854 Television NATIONAL RESEARCH DEVELOPMENT CORP 7 May 1974 [11 May 1973 20 March 1974] 22586/73 and 12361/74 Heading H4F A differential optical polarization detector for inspecting crops, soil surfaces, finger prints, stains and dust disturbances on lunar or planetary surfaces, comprises a television camera 1, Fig. 1, which generates two video signals representing two views of the same scene which differ only in respect of their polarization characteristics, and means 12-16 which compare these two video signals over the whole scene on a point-by-point basis producing a composite video signal which is displayed in monochrome or colour and/or fed to a suitable data processor. In Fig. 1 the camera includes two camera tubes 2 and 3 associated crossed polarizers 10 and 11, the output signals being gamma corrected 12, 13, summed 15, subtracted 14 and divided 16 to produce the composite signal which represents the spatial variations of the degree of polarization of light from the secene viewed by the camera 1. This composite signal (or the difference signal from differential amplifier 14) may be displayed on a monochrome CRT 17, or the composite signal and the brightness signal from summing amplifier 15 may be fed via a colour matrix unit (Fig. 2, not shown) to a three-gun shadow-mask colour CRT display. The colour matrix unit codes the composite (i.e. polarization) signal so that when it has a value corresponding to a substantial negative value of the degree of polarization it is displayed as blue, when it has a value corresponding to a positive value lying in the lowest of eight ranges it is displayed as green, highest of the eight ranges as red, and for the six intermediate ranges as a graded sequence from green to red, and when it has a value corresponding to a small value (either positive or negative) the brightness signal is displayed in monochrome. In Fig. 3 the camera includes one camera tube 110 and a linear polarizer 113 which is rotated through 90 degrees by drive 114 between picture scans, the resulting sequential video signal being gamma corrected 116 and fed to the summing and differential amplifiers 15 and 14 directly and via a picture period storage device 119, e.g. a storage CRT. A monitor 117 may be connected as shown. A wavelength limiting filter may be disposed in the path of the incident light, which light may be in the infra-red or ultra-violet range. Reference is made to using a single camera tube having two separate photo-sensitive screens, and to using circular or elliptical polarizers instead of linear polarizers.
Patent GB-579108-A (GB)
Title: Brake shoe adjusting means
IPC: F16D65/58
Filed: 1944-11-15
Abstract: 579,108. Brakes. SCHNELL, S. Nov. 15, 1944, No. 22592. [Class 103 (i)] In an automatic brake-shoe adjusting mechanism'having a plunger member 26 in the brake shoe in constant contact with the drum for effecting the adjustment necessitated by lining wear, the clearance of the shoe is determined by a pin 24 on the shoe web 6 contacting with the arm 17 of a L-shaped lever 16 pivoted to the stationary back plate 2 at 19 and having another arm 18 with a projection 20 engaging a cam surface 21 on the lever 10. The lever 10 is pivoted on an eccentric part of a revolubly adjustable pin 11 which is clamped to the backplate, and is spaced from the arm 17 by a spring 25. The swing of the lever 10 is limited by stops 22, 23 which contact the projection 20. The shoe lining, flange and web are cut away to receive the plunger 26 which carries a plug 28 of friction material preferably slightly harder than the lining, and the plug is flush with the lining 8 when the shoe web 6 contacts with the bottom of the slot 27 in the plunger 26. When the shoe is retracted, the plug remains in contact with the drum, and the web 6 separates from the bottom of the slot to an extent corresponding to the desired clearance of the shoe. During brake applications, the plug 28 is pressed against the drum 1 with the same intensity as the lining, so that the wear of the lining corresponds with the wear on the plug. The additional outward movement of the shoe, consequent on wear, coincides therefore with a corresponding outward movement of the plunger 26 which will allow the spring 25 to push the lever 10 outwardly. This brings a new part of the cam 21 into contact with the extension 20 and causes the arm 17 to swing correspondingly towards the shoe. If the drum expands due to heating, the plunger 26 will be pushed inwardly when the drum cools, thus effecting an adjustment of the arm 17 in a reverse direction. The stop 23 contacts with the extension 20 when the lining is worn out, the absence of subsequent adjustment giving warning of this.
