Title: Improvements in or relating to the dehydration of heat insulating walls of cold storage rooms
IPC: F26B21/04
Filed: 1947-09-05
Abstract: 641,487. Refrigerating; heat insulation. ISOLERINGSAKTIEBOLAGET WMB. Sept. 5, 1947, No. 24483. Convention date, Sept. 6, 1946. [Class 29 and 64(ii)] The insulation 22 of cold storage rooms 16 is dehydrated by relatively dry air introduced into the walls by a fan 40 which forces air through pipes 42, 46 to a channel 56 from which air flows in passages 52 down the sides and under the floor of the room to a channel 58 from which the air flows by other passages 52 to a channel 60 and by pipes 48, 50 to a chamber 35 containing a refrigerated coil 33 on which moisture is deposited, the dried air returning to the fan 40. An electric heater 62 defrosts the coil 33 under the control of a time switch 70 during which time the fan circulates air through the pipes 42, 66 and 50 and the chamber 35. The insulation 22 may be of cork slabs and may be covered with layers 24, 26 of plaster or wall-board, the warmer surface being also coated with a layer 28 of asphalt. The same fan system may circulate dehydrating air through a plurality of storage rooms. Reference has been directed by the Comptroller to Specification 634,664.

Title: Improvements in analogue to digital converters
IPC: H03M1/00
Filed: 1964-06-12
Abstract: 1,074,544. Counting apparatus; selective signalling. GENERAL PRECISION Inc. June 12, 1964 [June 12, 1963], No. 24532/64. Headings G4A and G4H. In a voltage digitizer of the type in which a known voltage is sequentially modified until it balances (to within a quantizing step), the unknown voltage, the known voltage is produced by a series-connected chain of appropriately weighted resistors 130 &c., and a constant current source, Fig. 3. The resistors can be selectively shunted individually by parallel connected contacts 84A &c. controlled by the stages of a memory, and in groups by contacts 92A &c. controlled by the stages of a control counter. In operation the memory is initially set to its maximum capacity, all contacts 84A &c. open, and the control counter is initially set with all of its stages off, all contacts 92A &c. closed. The stages of the control counter are then sequentially turned on, thereby sequentially opening contacts 92A &c. and sequentially putting more resistors in series with the constant current source. At each stage of the sequence the voltage produced is compared with the unknown input voltage and if at any stage it becomes larger than the unknown voltage the corresponding memory stage is turned off to thereby shunt the last resistor added to the chain by the control counter. The turning off of a memory stage occurs simultaneously with the turning on of the next counter stage. The Specification outlines a chopper comparator amplifier and a constant current source (Figs. 4 and 5, not shown). It also discusses the possibility of using pluggable modules for the resistance chain, thereby facilitating code changes, and various gating circuits for detecting spurious bit combinations. Counter.-The stages of the counter 76, 78, 80, 82 &c. are shown, Fig. 2, adjacent to the corresponding memory stages. Each counter stage is initially reset 12 off and each, except the first 76, can receive a clock pulse via its input " AND " gate providing it is off and providing the preceding stage is on.

Title: Collapsible optical projection screen unit
IPC: G03B21/58
Filed: 1960-07-14
Abstract: 947,218. Projection screens. AGFA A. G. July 14, 1960 [July 18, 1959], No. 24607/60. Heading G2J. A collapsible projection screen unit comprises a centrally-disposed supporting pillar to which are linked, on opposite sides, two parallel attachment members for a flexible screen and movable towards and away from the pillar while maintaining parallel relation therewith. As shown in Figs. 2 and 3, the screen 3 is stretched, when in use, between two rollers 4, one of which is spring-loaded, secured in respective halves 1 of a longitudinally-divided cylindrical shell. On extension of the screen by means of handles 2, the shell halves 1, as they move away from the previously enclosed supporting pillar 5, are maintained in parallel relationship therewith by means of the pivotal linkages of ribs 6 and struts 7. As shown in Fig. 6 the opening of the screen is assisted against the roller spring tension and frictional and inertial resistance, by a compression spring 13 which bears against a fixed disc 17 within the pillar 5 and serves both to push down the piston-like member 18 to cause outward splaying of the support legs and thereby, via cord 11 and a pulley, to exert upward pull on the piston-like member 10 thereby assisting the outward movement of struts 7 pivoted to the member 10 by pins 9. When the screen is fully opened, spring 12 is in slight tension. To close the screen, the handles 2 are pressed together. This causes extension of spring 12, as the element 10 is depressed until a catch 15 of the latter (see Fig. 8) is caught by a pin 16 fixed by spring 20 to the pillar 5. The tension in spring 12 is now sufficient to compress spring 13 via the cord 11 and member 18 and the legs are retracted against their spring loading at 14. When the screen is fully folded, the movements of the forces in struts 7 are such as to maintain closure until the shell-halves 1 are manually separated.

Title: Separating phenol from aqueous liquors by solvent extraction
IPC: C07C37/72
Filed: 1957-08-06
Abstract: Phenol is separated from the aqueous liquor by extraction with cumene, and the phenol is then separated from the solvent using an aqueous solution which contains more than 50% alkali phenate and a small percentage, e.g. 0.2% to 5%, of free alkali.  The cumene and the aqueous phenate solution can be mixed in a tower filled with Raschig rings; but it is preferable to effect the mixing in a gear pump or in a centrifugal pump.  In an example, a liquor from a technical process having a phenol content of 3.4% and a pH of 3.6 is extracted with cumene.  An aqueous solution containing 53.4% of sodium phenate and 1.6% of sodium hydroxide is then used to separate the phenol from the solvent, and gives an extraction yield of 99.8%.

Abstract: 1,211,424. Photographic developing apparatus. KALLE A.G. May 24, 1968 [May 26, 1967], No. 24960/68. Heading G2A. A continuous process for the development of photo-printing material by a gaseous developer, e.g. development of diazotype copies by humid gaseous ammonia, has the material conducted through a closed developing chamber which is subdivided into zones of different gas pressure, the material being subjected to a pressure which first increases to a value above atmospheric pressure and then decreases to a value below atmospheric pressure. Photo-printing material 8 is guided round a perforated cylinder 7, being pressed on to the cylinder by a gas-impermeable belt 9, which is guided by rollers 10. A rotary slide body 1 provided with slides 2 rotates in the same direction as, but at a faster rate than, the cyclinder and subdivided the latter into sectors 3, 4, 5, 6 all at different pressures. Developer gas is admitted to sector 3 through a valve 13 and a pipe 14 from a storage tank 16, and gas is drawn from sector 5 through a valve 13 and pipe 15 back to the tank. Sectors 3 and 6 are at pressure below atmospheric, whilst sector 5 is above atmospheric pressure. The cylinder is formed from a rigid metal structure provided with numerous bores and lined on its inner and outer surfaces with a thin layer of perforated stainless steel. The edges of the cylinder are unperforated but covered by the gasimpermeable belt to provide a gas seal. A further endless belt may cover the belt 9 in the area corresponding to high pressure sector 9. In another embodiment, Fig.8, (not shown), a triangularly shaped rotor (34) rotates eccentrically within a chamber (36) of suitable shape,the chamber being thick walled and having 7 inset rollers (39) for guiding the photo-printing material around its outer surface, borings (37) in the chamber wall connecting the pressure sectors to the material. Heating elements may be provided to accelerate development, and exhaust devices provided to remove small amounts of ammonia which may escape from the development zones.
