Title: Improvements in and relating to the treatment of vulcanised rubber
IPC: C08J11/20
Filed: 1934-05-28
Abstract: Vulcanized rubber is plasticized for re-use by incorporating with comminuted rubber, e.g. tyre scrap, a solvent comprising heveene and like higher boiling point oils obtained by distilling crude or vulcanized rubber and rectifying the distillate for the removal of its isoprene fraction, the process being carried out at a temperature and for a period of time sufficient to ensure devulcanization.  The amount of solvent may be as low as two and a half per cent of the rubber, or sufficiently high to dissolve the rubber completely.  In an example, finely comminuted tyre tread is heated to from 120-150 DEG  C. with 2 1/2 per cent of the solvent over a period of 12-15 hours.  In another example, finely comminuted vulcanized waste is placed in a vessel with 4-5 times its weight of solvent and heated at a temperature not exceeding 150 DEG  C. until all the rubber is dissolved.  In other examples, the solvent is incorporated with the comminuted rubber in a roller mill.

Title: A method for the rastered reproduction of half-tone pictures
IPC: H04N1/405
Filed: 1969-04-28
Abstract: 1,269,093. Facsimile apparatus. DR. ING RUDOLPH HELL. 28 April, 1969 [4 May, 1968], No. 21640/69. Heading H4F. To improve the density gradations in a rastered reproduction of a half-tone picture while using only a given number of raster dot sizes, density values which lie between any two adjacent density gradations which correspond to specified raster dot sizes are reproduced by mixing with statistical distribution raster dots of different sizes (preferably the two dot sizes for the two adjacent density gradations) particularly in a proportion which corresponds to the ratio of the differences between the density value to be reproduced and the two adjacent density gradations. To effect this statistical distribution the video, derived by photo-electrically scanning an original, before it has been quantized, i.e. assigned at regular moments in time determined by a timer to one of a number of discrete voltage values corresponding to the raster dot sizes, and expressed in binary code, has superimposed thereon an alternating voltage, e.g. a triangular or saw-tooth alternating voltage, the amplitude of which is preferably equal to half the difference between the two successive discrete voltage values of the video signal, while its frequency is anharmonio in relation to the frequency of the timer and is preferably at least a quarter of the timer frequency (Figs. 1b and 2, not shown). Since the human eye sees fewer contrasts in the light portions of a picture than in the dark portions the voltage ranges associated with the discrete voltage values are preferably arranged to increase with increasing density in accordance with the well-known Mussell physiological sensitivity curve, and the amplitude of the alternating voltage for superimposition is also arranged to increase with density, that is it is rendered dependent upon a voltage obtained by a non-linear distortion of a voltage proportional to the density of the picture (Figs. 3 and 4, not shown). The peak-to-peak rise of the alternating voltage is preferably always approximately equal to the voltage range through which the picture signal voltages passes. Instead of grey shades the present invention may be applied to the saturation values of colours. The quantized and binary coded voltage values are either used immediately to control the reproduction of a picture or are stored on a record carrier such as a punched tape. Preferably data of the various raster dot sizes are stored in a ring core store from which they are recalled in response to data read out from the record carrier.

Title: Improvements in apparatus for obtaining a measure of a variable
Inventor: MCCOLL WILLIAM
IPC: G01K1/14
Filed: 1958-07-07
Abstract: 861,481. Measuring electrically. BABCOCK & WILCOX Ltd. July 7, 1959 [July 7, 1958], No. 21771/58. Class 40 (1). [Also in Groups XX and XXXVI] In a device for obtaining a measure of a variable at different points in a space, a transducer, e.g. thermocouple 33, Fig. 1, is mounted at the end of a telescopic arrangement of tubes 1, 2, 3 and 4 so that the thermocouple may be traversed across the space A, the position of the thermocouple being governed by cable 20 winding on the motor-driven drum 45. The cable is kept tensioned by compressed air supplied through connector 14 and exhausted through pipe 39. Passage of air through tubes 1, 2, 3 and 4 cools them, and the exhaust, being downwardly directed at 39, assists to support the tube when fully extended. The thermocouple may be continuously traversed across the space A by arranging limit switches to operate and reverse the drum drive motor 44 whenever the tubes reach their fully extended or fully retracted position. Alternatively, it may be arranged that, on operation of a start button, the thermocouple makes complete traverse across the space and then returns to its retracted position and automatically stops. Cable 20 besides controlling the traverse may also carry the thermocouple output signal to indicating or recording apparatus, alternatively separate cables may be employed. Also described is an alternative form of cable clamp and air exhaust arrangement, Fig. 3, where the exhaust is emitted from an annular space 57 and is directed back along the outside of the tube where it tends to deflect any air leaking at the telescopic joints from entering the region of the thermocouple. Fig. 1 shows the invention mounted in an access tube 25 in the wall of a boiler to measure the gas temperature at various points in the gas flow path at the entry to the convection section. Bellows 27 seal the access tube 25 to tube 1.

Abstract: 797,219. Orientating cans. PETFOODS, Ltd., [formerly CHAPPIE, Ltd.]. July 20, 1956 [July 28, 1955], No. 21874/55. Class 78 (1). A can-orientating machine comprises a shoot 10 which has a hole 16 and guides 19, the cans being advanced thereto by conveyer 13. Each can which arrives at shoot 10 positioned on its flat cylindrical face passes unchanged to position 142, where it then slides on to conveyer 23 so as to be carried away thereby correctly orientated, as shown, with the plain cylindrical face parallel to the length of the conveyer. Each can which arrives positioned to roll down shoot 10, its flat cylindrical faces being parallel to the sides 11 of the shoot, falls down hole 16, and, by means of twist shoot 26, is twisted so as to be discharged by conveyer 27 (not shown) correctly orientated as above and fed to conveyer 23. Each can which arrives positioned to slide down on its curved surface but with its plain cylindrical faces perpendicular to the side of the shoot (i.e. position 14c shown) is tipped by hole 16 to take up position 142 and, as before, is discharged by conveyer 23 properly orientated. All cans are thus uniformly aligned.

Title: Improvements in or relating to thermionic valve amplifiers
IPC: H03F1/36
Filed: 1939-07-28
Abstract: 536,089. Valve amplifying circuits. BLUMLEIN, A. D. July 28, 1939, No. 21912. [Class 40 (v)] The invention relates to a thermionic amplifier for providing an output representing a fractional power of the input so that the gamma value of a film in a television transmission may be reduced below unity. Fig. 1 shows an arrangement in which the signal is applied to the grid of a high impedance valve 2 which may include a resistance in its cathode lead to ensure, by negative feedback, that the current is proportional to the input. The valve 3 is maintained at a fixed bias and arranged to operate over a part of its characteristic curve exhibiting the necessary curvature in terms of grid voltage and anode current. A push-pull pair of valves may be fed from the grid and cathode of a valve working on the curved part of its characteristic and the push-pull valves may be provided with a common cathode resistance, Fig. 2 (not shown) so that differences of potential applied to the grids are amplified but not the absolute potential of the grid and cathode. Fig. 3 shows a valve 2 provided with a feedback resistance 17 to ensure linear current changes with direct coupling, as described in Specification 456,450, to valve 11 provided with negative feedback. With this arrangement non-linearity of the valve 11 produces the required fractional power output by feedback at its grid. The anode resistance 13 may be made infinite and the coupling 14 may be made zero, while the provision of resistance in the cathode lead of the valve 11 will control contrast.
