Title: Improvements in or relating to television receivers
IPC: H01J29/14
Filed: 1938-03-18
Abstract: 514,155. Television receivers. SCOPHONY, Ltd., and ROSENTHAL, A. H. March 18, 1938, No. 8396. [Classes 39 (i) and 40 (iii)] A screen of the kind disclosed in Specification 513,776, e.g. an alkali halide, is scanned by a modulated beam of radiant energy, e.g. a cathode ray or light beam, to change the refractive index of each elemental area of the screen in turn in accordance with received signals, and this change is utilized to modulate light from a constant source to reproduce the picture. The light source 13 is imaged on a bar 14 by lens 12, and changes in the refractive index of the screen 9 cause light to pass the bar ; a lens 15 images the screen 9 on the viewing screen 16. Since the amount of light passing the bar is proportional to the first differential of the length of the optical path of the light, the screen 9 may be formed with a notched or similar surface 17, Fig. 2, so that the change in the optical path produced by the variation of the refractive index will produce a light modulation proportional to the scanning beam modulation ; the bar may then be replaced by a plurality of bars. This proportionality may also be obtained by varying the scanning beam at high frequency or by placing a fine grating near or on the crystal, Fig. 3 (not shown). The change in the refractive index may vary the amount of light reflected, Fig. 4 (not shown) or transmitted.
Patent GB-357167-A (GB)
Title: Manufacture of new cellulose compounds
IPC: C08B13/02
Filed: 1930-03-15
Abstract: Cellulose compounds are produced by acting upon an alkali-soluble alkyl cellulose, or an alkalisoluble or insoluble aralkyl cellulose, or an alkalisoluble or insoluble cellulose ether of an oxyalkyl monocarboxylic acid, with carbon bisulphide in the presence of alkali.  In the preparation of the ethers, catalysts such as salts of copper, nickel, silver, zinc, or iron may be present.  In an example, wood pulp or cotton linters are steeped in caustic soda solution and after some time the alkali cellulose is pressed, and comminuted in a shredder.  Dimethyl sulphate is added and when the reaction is complete the mass is washed and pressed.  It is then mixed with caustic soda solution, pressed, and comminuted.  Carbon bisulphide is added and the xanthated mass is dissolved in caustic soda solution. The product is precipitated with methyl or ethyl alcohol, washed with alcohol and ether.  Solutions of the product in caustic soda may be precipitated with dilute mineral acids, or salts, or alcohol.  The process may be varied by omitting the washing of the cellulose ether before the xanthating step.  In another example the cellulose ether is treated with such a quantity of caustic soda solution that a residue remains undissolved.  The clear filtrate is acidified and the resulting precipitate is washed, dissolved in caustic soda, and treated with carbon bisulphide.  Instead of dimethyl sulphate, diethyl sulphate, monochloracetic acid in the form of its sodium salt, a -bromopropionic acid or a -bromo-isobutyric acid or alkali salts or esters thereof may be used.  Iodine derivatives may be used instead of chlorine or bromine derivatives.  Instead of caustic soda, caustic potash may be used.  Instead of caustic alkali, a sulphonium hydroxide such as trimethylsulphonium hydroxide may be used. Specifications 177,810, 203,346, 203,347, 231,809, and 231,810, [all in Class 2 (ii), Cellulose &c.], are referred to.  The Provisional Specification refers also to Specification 356,776.

Title: Marking of carriageways
IPC: E01F9/594
Filed: 1972-02-25
Abstract: 1388121 Road traffic signals ENVIRONMENT SECRETARY OF STATE FOR 22 Feb 1973 [25 Feb 1972] 8720/72 Heading G4Q [Also in Division E1] A variable carriageway marker, which may form a variable marking line for a bus lane or for tidal traffic flow on a three- or five-lane road comprises an elongated flexible sleeve 10 of lowfriction material extending along an elongated platform 4 located below the carriageway surface (e.g. in a trough 33), the parts of the sleeve on either side of an intermediate part 11 hanging in loops 12, 13 whose relative sizes can be varied by means such as inflatable inner tubes 16, 17 to move the exposed layer 14 of the intermediate part 11 relatively to the carriageway. The layer 14 may have marking lines painted thereon. As shown, inflating tube 16 while deflating tube 17 (e.g. by means of a time switch-controlled roadside air pump, not shown), will cause the upper layer 14 to move laterally over the lower fixed layer 15 of the intermediate sleeve part 11, thereby exposing either an area matching the carriageway surface to indicate an absence of marking or exposing a different lane marking, e.g. to change a single or dotted white line to a double line at different times of the day. Rigid rubber or plastics tubes 18, 19 within the inflatable tubes 16, 17 serve to retain the sleeve loops in the trough 33. A low-friction nylon liner 5 bonded in the steel trough 33 has serrated edge portions retaining rubber wedges 24, 25. The platform 4 comprises a bolted-in I-girder covered with resilient material 9 to which the layer 15 is adhered. Heater elements 34 may be provided. The sleeve 10 may be formed either (as shown), by a one-piece envelope or by a single web having its longitudinal edges fixed to the platform 4. In an alternative embodiment, Fig. 2, a further inflatable tube 32 is provided between the layers 14, 15 to cause the intermediate part 11 to be raised when required to provide a resilient kerb which may be coloured white, the sleeve itself having wedge portions 26, 27 and thickened gap-sealing portions 28, 29 provided with kerb drainage recesses 30. In a modification, Fig. 3 (not shown), the lined built-up steel trough 33 of Fig. 1, is replaced by a lined or unlined rolled steel channel (35)-possibly with anchoring projections- and the steel girder 4 is replaced by a platform (38) of rubber or plastics which may be stiffened by pressure liquid in a longitudinal bore (39); the lower sleeve layer (15) may have a thickened portion (42) keying in a slot of the platform; additional inflatable tubes may be provided in upper spaces (43, 44) to pinch the intermediate sleeve part (61) in its adjusted position, and the spaces (43, 44) may be filled with lubricant. The Fig. 3 embodiment may be adapted to provide a raised carriageway marking by pumping fluid into the intermediate part (11)-with or without an additional inner tube-while allowing both loops (12, 13) to deflate so that the part 11 rises above the carriageway surface.

Abstract: 886,015. Presses for separating liquids from solids. ROSE, DOWNS & THOMPSON Ltd. March 17, 1958 [March 19, 1957], No. 8922/57. Class 46. A feed worm 1 is aligned with, and independently mounted from, a compression worm 2, both being located in a common reticulated chamber 5. Preferably the worms are cantilevered into the chamber from opposite ends, as shown. Oil is discharged from a variable gear pump 55 at 56 and passes first to a hydraulic motor 58 and thence to a hydraulic motor 62, returning to the pump at 57, valves 60 and 64 being closed and valve 66 being open. Preferably, however, the oil is pumped to the motors in parallel, valves 60 and 64 being open and valve 66 closed. In the latter case the motor 62 taking the lesser load will take more oil and speed up, while the motor 58 taking the greater load will take less oil. In Fig. 1 (not shown), worm 2 is driven by a motor through spur gearing, which also drives an interrupted-helical cake conveyer and a worm oil conveyer mounted on connected shafts. The feed worm 1 is driven by a separate motor through worm gearing. Each of the shafts 3 and 4 is hollow and encloses a pipe through which water is pumped from the driven end to the free end, the water returning along the space between pipe and shaft. The compressed cake is discharged between an axially slidable sleeve 25, mounted on a collar 21, and a conical boss 19 keyed to the shaft 4.
