Filed: 1948-05-25
Abstract: 655,893. Paper and like bags. ROBINSON, Ltd., E. S. & A., DAVIES, K. W., and WILLS, S. C. F. May 25, 1948, No. 14154. [Class 94(ii)] [Also in Group VIII] A method of making papei bags comprises the application of a stream of hot air or other gas to the outside of a seam in a bag tube which is to be sealed. thereby heating the contacting surfaces of the seam by conduction through the plys of material being sealed. As shown, a web 11 drawn from a reel 12 is formed into a tube having an overlapping longitudinal seam which passes beneath a nozzle 33 discharging a stream of hot air adapted to soften the heat-sealing material comprised in the seam area of the tube The seal is completed by passing the seam between pressure rolls 19 and then under a nozzle 35 which emits a stream of cold air. The sealing of transverse seams is effected by means of a pair of elements 36, 37 which grip the tube and travel with it while applying hot air to it through orifices formed in the elements. The latter are slidably mounted on a frame 48 adapted to be swung about an axle 41 by cranks carried by an axle 43. The element 36 is mounted resiliently, while the element 37 is adapted to be reciprocated by means of an eccentric 54 mounted on the axle 43. After sealing is completed, the tube is severed into bag lengths by cutter rolls 23. Air is passed over heated electrical resistances and issues continuously from the nozzle 33, but is supplied to the elements 36, 37 only when these are in contact with the bag tube. It is stated in fhe Provisional Specification that the sealing may be effected in two stages, the temperature in the first stage being comparatively low and in the second stage higher to complete the sealing.
Patent GB-998918-A (GB)
Title: Improvements in or relating to nitrodiphenylamine dyestuffs
IPC: C09B51/00
Filed: 1963-04-09
Abstract: The invention comprises 4-(arylamino)-3-nitrobenzenesulphonamides in which one or both of the hydrogen atoms of the sulphonamide radical is replaced by a lower cyano-alkyl radical.  The preferred dyes are of the formula <FORM:0998918/C4-C5/1> where X is hydrogen, halogen, lower alkyl or lower alkoxy, Y is hydrogen, lower alkyl, lower hydroxyalkyl, lower alkoxy-lower alkyl or lower cyano-alkyl and RCN is lower cyano-alkyl. The various lower groups contain a maximum of six carbon atoms excluding, in the case of the cyano-alkyl group the carbon atom of the cyano radical.  The dyes are produced by reacting a primary arylamine with a 4-nitro-3-nitro-benzenesulphonamide in which one or both hydrogen atoms of the sulphonamide radical are replaced by a lower cyano-alkyl radical.  The dyes can be converted to readily dispersable powders by mixing with the usual dispersing agents, e.g. sulphite cellulose waste liquor products and are particularly suitable for dyeing or printing polyalkylene terephthalate polyesters especially in fibrous form.  Examples are furnished and suitable starting materials listed. Specifications 609,943 and 609,944 are referred to.

Title: Photographic material for making half-tone records
IPC: G03F5/00
Filed: 1951-06-15
Abstract: 699,659. Photographic material for making half-tone records. KODAK, Ltd. June 15, 1951 [June 17, 1950], No. 14178/51. Drawings to Specification. Class 98 (ii). The material comprises a transparent support with a uniformly thick photosensitive silver halide emulsion layer thereon having a maximum gamma greater than four in which the emulsion is desensitized in a half-tone pattern, the maximum gamma in the desensitized areas, if it is reduced at all, being still greater than two. The material may be made by subjecting a high contrast emulsion as used for half-tone records or reproduction of line drawings to a flash exposure as from a vapour discharge speed lamp through a half-tone ruled screen out of contact with the emulsion, or, in the preferred form, through a half-tone contact screen, to produce Clayden desensitization. The flash exposure is adjusted so that it does not exceed the point at which a latent image starts to form. Exposure of the material to a continuous tone image and normal processing, particularly in surface developer, gives a halftone negative directly. Preferably the points of minimum desensitization have substantially no desensitization and the most sensitive areas, between the desensitized areas, include a latent image dot, produced, when a ruled screen is used by use of a different aperture from that used for the desensitizing exposure or by a shift of the screen, with a lower intensity longer duration flash. The latent image dots may be very small and have the purpose of constituting a centre at which development will start; or they may fully complement the desensitized areas to act as a partial pre-exposure of certain areas to give increased sensitivity in the shadows when making a half-tone negative and hence to lengthen the effective range of the present desensitized screen when the available desensitization range covers only the high lights to middle tones. One feature of the invention provides a photographic material for making half-tone posters in which it is convenient to reproduce only 3, 4 or 5 tones, that is highlights as white, shadows as black and 1, 2 or 3 intermediate values of grey (or up to 8 tones for colour work), and for this the desensitizing exposure is made through a contact half-tone screen having a stepwise density distribution as used for poster work and a latent image longer duration exposure is made with the screen shifted half the width of one element or with the screen out of contact with the emulsion. Specifications 474,911, 544,033, 628,871 and 628,872 are referred to.

In Fig. 12, the output of transducer 1 is bandpass-filtered, 42, sampled, 3, and compared, 4, with a ramp wave generated by a D-to-A convertor 91 and counter 90 which counts clock pulses which also step the addresses in a memory 5, when comparator 4 detects coincidence 1 is added to the number in the currently addressed store site so that the statistical distribution function of the amplitude of the samples of the transducer output is built up in store 5. This read out to a computer 18 and via a D-to-A converter 16 to an analogue display. For deriving the statistical distribution function of the frequency components in the transducer output, the filtered signal is fed to a zero-cross detector 43 for controlling the resetting times of an integrator 44, whose output is periodically sampled, 301 and compared, 302, with the ramp wave, the moment of coincidence determining which of the store sites in memory 303 is incremented. The resulting frequency distribution fuction is read out to the computer 18 and via a D-to-A converter 94 to an analogue display. A sample counter (51) Fig. 14 (not shown) may be provided for stopping the sampling when a pre-set number of samples has been taken. The memory 303 may comprise an adder (84) and shift register (86) connected to form a recirculation loop.
