Abstract: 1,037,342. Photographic cameras. INTERNATIONAL POLAROID CORPORATION. March 8, 1963, No.9364/63. Heading G2A. A photographic camera of the type wherein the exposed image-recording sheet is superposed with a receiving sheet and processing liquid distributed therebetween, is provided with a supplementary exposure means for uniformly exposing a portion bordering each image area so as to produce a white border around each transfer image. The supplementary exposure may be limited to a transverse strip between the image frames, in which case the width of the imagerecording sheet is limited to the image width and the receiving sheet is made wider to include the top and bottom borders as described in Specification 1,037,343. Alternatively, the entire border area surrounding the image area may be given a supplementary exposure. In Fig. 1, the imagerecording sheet 32 is unwound from spool 36 and, after exposure, is pressed into contact with receiving sheet 40 by rollers 42, 44 while processing liquid is distributed between the sheets as described in Specification 1,037,343. The transverse areas between the images are exposed at 38 by means of a lamp or other source of radiation such as a radioactive source, or means may be provided for admitting environmental light. The intensity of the source should be insufficient to cause fogging during movement of the light-sensitive material. As shown in Fig. 3, the supplementary exposure is given by a luminescent material coated on the inside surface of a curved window 80 and excited by beta-radiation from a radio-active material such as tritium provided in chamber 84. The source is provided with a cover 86 which is mounted on arms 88 and drawn over the window 80 during movement of the photosensitive sheet 32 by frictional contact therewith. Fig. 5 shows a frame for exposing the entire border area. The photosensitive material 32 passes between the rear surface 124 of the frame and the back of the camera.

Title: Process for the polymerization of ethylenically unsaturated monomers
IPC: C07C309/13
Filed: 1960-03-17
Abstract: Polymers containing sulphonic acid groups are prepared by polymerizing ethylenically unsaturated monomeric compounds having a double bond activated by an electrophilic group, the polymerization being initiated by free radicals derived from the thermal decomposition of a sulphonated azo-nitrile of the general formula <FORM:0916782/IV(a)/1> wherein R is a trivalent saturated acyclic hydrocarbon radical containing not more than 4 carbon atoms, A represents a hydrogen atom or an alkoxy carbonyl radical, R1 is a C1-4 alkyl group and X is an atom of hydrogen or an alkali metal. The resulting polymers contain terminal groups of the general formula <FORM:0916782/IV(a)/2> wherein X, A, R and R1 are as above defined. The preferred monomers have the general formula <FORM:0916782/IV(a)/3> wherein Y is a cyano, carboxy amido, acyloxy or alkoxy carbonyl group and Z is H or a C1-4 alkyl group.  In examples: (1) acrylonitrile is heated with water, either saturated with CO2 or containing sulphuric acid, and azo-bis-(sodium a -methyl butyronitrile in a CO2 atmosphere yielding a sulpho-polymer; films made from the polymer are dyed; the azo compound may be replaced by azo-bis-(sodium isobutyro-nitrile sulphonate) or azo-bis-(sodium a -methyl-b -ethoxy carbonyl butyronitrile sulphonate); (2) acrylamide is polymerized in water containing the first mentioned azo compound at 50 DEG C.; (3) vinyl acetate is similarly polymerized in aqueous polyvinyl alcohol solution.  The polymers have improved dyeing properties and in Example (1) a film of the polyacrylonitrile is dyed with a green basic dye in aqueous sodium acetate-acetic acid solution.  The preparation of the azo-nitriles is described (see Group IV(b)).ALSO:Azo-nitriles of the general formula <FORM:0916782/IV (b)/1> in which R is a trivalent saturated acyclic hydrocarbon radical, containing not more than 4 carbon atoms, A is hydrogen or an alkoxy carbonyl radical, R1 is a C1-4 alkyl radical and X is hydrogen or an alkali metal, are prepared by reacting a ketone X-SO3-R(A)-CO-R1 with hydrazine and hydrogen cyanide and oxidising the resulting hydrazo compound, for example, with chlorine. The first step is preferably effected in an inert solvent e.g. water, and the hydrazine is used in the form of an acid addition salt and the HCN in the form of a metal salt. Examples describe the preparation of azo-bis(sodium a -methyl-butyronitrile-sulphonate), azo-bis(sodium-isobutyronitrile-sulphonate) and azo-bis(sodium a -methyl-b -ethoxycarbonyl butyronitrile sulphonate).  The compounds may be used as polymerization initiators (see Group IV(a)).

Abstract: 1,263,503. Gas filters. GREEN BAY RESEARCH CORP. 21 Feb., 1969, No. 9582/69. Heading BIT. [Also in Division F1] The passage of gases from the crankcase of an i.c. engine through a filter 13 (via inlet 2 and outlet 5) to the air inlet manifold of the engine is controlled by valves 31, 33 arranged in series. The valves comprise balls adjustably loaded by springs 34, 35, and when the engine develops power, the pressure differential lifts ball 31 from its seating 30 and lifts ball 33 to allow the gases to pass through apertures 41 into chamber 20, from where they pass through passages 19 and 17 to the outlet 5. The springs 34, 35 yield further to allow the ball 33 to uncover further sets of apertures 41 when they are heated by the gases. Gas flow from the crankcase is restricted under highvacuum conditions by the seating of the ball 31 against an interrupted shoulder 32. As shown, an additional spring-loaded ball valve 25 is provided to allow the passage of gases even under idling conditions when the pressure differential is low. Drain valves 45, 46 open automatically when the engine is stopped, and a drain plug 44 is provided for the passages 17, 19.

Title: Improvements in or relating to photographic developers
IPC: G03C5/305
Filed: 1943-06-16
Abstract: 566,314. Photographic developers. ELLIOTT & SONS, Ltd., HOWE, D. J. T.; and GLASSETT, J. W. June 16, 1943, No. 9630. [Class 98 (ii)] A photographic developer, other than one in which the developing agent is predominantly a paraphenylenediamine, comprises in addition to the developing agent and other constituents, a cationic surface-active agent, e.g. N-dodecyltriethylammonium bromide, N - dodecylpyridinium bromide, and N-dodecyl-alpha-picolinium bromide. The surface-active agents are not effective with developers containing a substituted or unsubstituted p-phenylenediamine. The surface-active agent may be incorporated in a stock developing powder. Developers containing hydroquinone and alkali, e.g. NaOH or KOH, and containing metol and a weak alkali, e.g. borax or trisodium phosphate, are referred to. The addition of the surface-active agent to the developer results in an effective increase in speed of the emulsion developed. The surface-active agent may be a tetra-alkyl ammonium or phosphonium salt in which one of the substituents is an organic lipophylic group containing a chain of at least 8 members selected from the group consisting of C, S and O atoms and aromatic ring systems, or may be a quarternary salt of a heterocyclic nitrogen base containing as an N- or other substituent a liphophylic group. For negative materials, up to 25 milligrams of the agent may be incorporated in 100 c.c. of metol-hydroquinone developer. For positive materials, e.g. papers, up to 2.5 c.c. of a 1 per cent solution may be added. The final image may be an ordinary or reversed silver, silver salt, other metal or metal salt, or dye image, including images obtained by toning, dye-destruction, and colour development. Examples are given of results obtained by developing test strips exposed behind step wedges.

Abstract: 456,709. Television. PERCIVAL, W. S., 2, Ealing Village, Hangar Lane, Ealing, London, and MANIFOLD, M. BOWMAN-, Heathcot, Worplesdon Station, Surrey. April 9, 1935, Nos. 9710/36 (divided out of 456,651) and 13733/35. [Class 40 (iii)] The beginnings of field-traversal signals for interlaced scanning are in phase with the beginnings of line-synchronizing signals in intervals between trains of picture signals, and successive field-traversal signals are of different wave form, Figs. 1 and 2 (not shown). The signals are applied negatively to valves 21, 22 to interrupt the anode current and cause triangular positive pulses across condensers 36, 37 which are greater in the case of the field-traversal signals. The cathode of a diode 33 is connected to a positive potential on a potentiometer 31 such that current flows only when a field-traversal signal is operative, and the cathode of a diode 32 is connected to a more positive potential such that only alternate longer field-traversal signals cause current to flow. Windings 34, 35 control blocking oscillators as described in Specification 455,375. According to a modification the field-traversal signals are integrated across a condenser and trigger a blocking oscillator after attaining a critical voltage in a time which differs for alternate field traversals, Fig. 3 (not shown). Specifications 425,220, 438,905, [Group XX], and 456,564 also are referred to.

Abstract: 708,482. Refrigerating. BUCHER, E. April 18, 1952 [April 18, 1951], No. 9809/52. Class 29 Absorption apparatus in which the generator 17 is replenished intermittently during continuous evaporation has a loaded transfer valve 19 interposed in the flow of refrigerant from the generator to the condenser 3, and a syphon 26, 27 associated with the generator for periodically supplying poor solution to operate a differential piston pump 28 through a snap-over valve 31, the pump forcing rich solution from the absorber 2 to the generator 17. The absorber 2 and condenser 3 are contained in a hot water boiler 1 with inlet and outlet 4, 5 and a thermostatic safety valve 6 to prevent excessive pressures in the condenser. The condensed refrigerant passes by a pipe 7 with a diaphragm 9 to keep back vapour to a heat exchanger 8 and evaporator 11, the vapour from which passes through the heat exchanger 8 to cool the incoming refrigerant. The evaporator is in two parts connected by a pipe 13 and any solvent carried along by the refrigerant collects in the lower portion of the evaporator and overflows at 15 into the conduit 16 by which the vapour passes from the heat exchanger 8 to the absorber 2. A boiler 17 heated by a heater or burner 24 supplies vapour to the condenser 3 by a pressure-controlled valve 19 and pipe 18 and comprises an outer container 20 connected by a float valve 25 and the syphon 26, 27 with an inner container 21. When the inner container 21 fills with liquid the valve 25 closes suddenly and starts the syphon to transfer the poor solution to the bottom of the outer container 20 whence it flows through a pipe 29 and liquid heat exchanger 30 to the snap-action slide valve 31, which in one position directs the liquid into a cylinder 32 to force down a differential piston 34 against the action of a spring 39. The bottom surface of the piston 34 forces rich liquor through a valve 37, pipe 38, and the liquid heat exchanger 30 to the inner container 21 of the boiler. The valve 31 is then reversed and the piston 34 is raised by the spring 39 forcing the poor solution through a pipe 33 into the absorber 2 and drawing in strong solution through a pipe 35 and valve 36 to the space beneath the piston. A device 40 controls the heat supply to the heater 24 in accordance with the pressure in the absorber.
