Patent GB-378720-A (GB)
IPC: G03C7/14
Abstract: 378,720. Projecting lenticular films. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort - on - Main, Germany. Nov. 12, 1931, No. 31375. Convention date, Nov. 13, 1930. Drawings to Specification. [Class 97 (i).] Lenticular films are projected in their true colours by disposing between the film and the objective a multi-colour filter which is geometrically identical with the colour filter which, in taking the pictures, is arranged either in front of, or in, or behind the objective, or with the virtual image thereof, and the distance of which from the film plane is adjusted as closely as possible to that of the filter used when taking the picture. Where the films have been taken by adjusting the objective so as to obtain the requisite focusing for near or distant scenes and placing the filter either in front of or in the objective, the distance of this filter from the film plane during the projection is equal to the mean distance of the filter employed during the exposure. Specification 10611/09, [Class 98 (ii), Photographic processes &c.], is referred to.

[Also in Division B3] In brazing a sintered hard metal tip to a steel shank to form a tool suitable for cutting coal, stone and rock, mating surfaces are formed on the tip and shank, one of which has two or more ridges to form a narrow gap between the surfaces when they are brought together with line contact between the ridges on the one surface and the other surface, the surfaces are brought together, the shank and tip are heated by furnace, induction of torch heating and brazing metal is supplied to the gap to be held therein by capillary attraction. The ridges may be formed on the tip or the shank but preferably on the tip. A tip 1, Fig. 1 (not shown), having two semi-circular section ridges traversing it is placed in contact with a shank, the tip and shank are heated and brazing metal is applied to the gap to be sucked in by capillary action. In another embodiment a tip 1, Fig. 4, having a convex surface 6 carries two ridges 3 and mates with a concave surface 6<SP>1</SP> of the shank 5. Brazing is effected as before. Ridges may radiate outwards from the centre of a flat tip and brazing metal may be placed at the centre of the tip, between the tip and shank surfaces. The tip may have ridges radiating from a point on one edge of a flat tip. In examples a flat tip having three rounded parallel ridges is brazed to a steel shank using high frequency induction, brazing metal and flux being applied to the gap. The cross section of the ridges may be triangular and brazing metal the wires, strip or rod form may be used.

Title: Memory system for digital computers
IPC: G06F12/06
Filed: 1974-09-04
Abstract: 1486430 Memory systems COMPUTER AUTOMATION Inc 4 Sept 1974 [10 Sept 1973] 38727/74 Heading G4A Upper and lower address limits for each of a plurality of memory modules are automatically generated to maintain continuous address boundaries between the modules, even when modules are replaced by modules of different storage capacities. Memory modules Fig. 3 Each module has a register LMCR which may be hard-wired to represent the capacity of that module. A serial input MBIN representing the start address for that module is input to a serial to parallel shift register SPSR where the start address is stored. An adder ADR generates the upper address limit for the module and supplies it to an output parallel to serial shift register PSSR which supplies the start address for the next module in a predetermined series. The start address for the first module of the series is generated by a unit SAG Fig. 2 in the processor module, and is either zero or a value representing the capacity of a memory sub unit MSU if such is provided in the processor module. The total memory capacity is generated by the last module in the series and is entered over bus TMCC into a register TMCR in the processor module for subsequent comparison at TRD with the address part of an instruction, an interrupt signal being generated if the instruction address exceeds the maximum memory capacity. The calculation of the module address limits is automatically initiated following switching on of the power supply, details of which are given in Fig. 7 (not shown). During operation each address ADR supplied by the processor over the address bus is compared in each module with the coresponding upper and lower limit addresses to produce an output MGO when the address lies between the limits for that module, so as to enable the corresponding memory matrix MUN. The arrangement enables the memory modules to be connected anywhere within the predetermined series without the necessity for manually altering the address limits for the module in accordance with its new position. The modules may be plug-in circuit boards, Fig. 9 (not shown). The upper address limit comparator in each module may be dispensed with if provision is made for the last responding module to inhibit all preceding modules.

Title: Improvements relating to the sulphation of aliphatic alcohols, and related compounds
Inventor: ROELE PIETER
IPC: C07C305/04
Filed: 1962-10-12
Abstract: Monohydric aliphatic alcohols having at least 8 carbon atoms or their ethylene oxide condensates are sulphated with a sulphur trioxide/inert gas mixture in two stages, in which, in the first stage, with a relatively long residence time of from one-half to two hours, the alcohols are reacted with an amount of sulphur trioxide smaller than that stoichiometrically required for complete conversion of the alcohol to ester so that a decomposition of the acid reaction mixture takes place of less than 5%, preferably less than 1%, of the acid reaction mixture, and in which, in the second stage, sulphation is completed with a relatively short residence time of from about one to 15 minutes, followed by immediate neutralization of the reaction mixture. The first stage of the process may be carried out batchwise or continuously and the second stage is preferably carried out continuously. The process is suitable for alcohols having a melting-point above 50 DEG  C., e.g. tallow, lauryl, myristyl and coconut alcohols.  Examples are given for the sulphation of tallow alcohol (first stage batchwise and continuous), coconut fatty alcohol (first stage batchwise and continuous), a secondary branched tridecyl alcohol (first stage continuous), lauryl alcohol which has been condensed with two moles of ethylene oxide (first stage continuous), and oleyl alcohol (first stage continuous).

Abstract: The invention comprises the hydroxymethyl and aminomethyl derivatives of maleic hydrazide (pyridazine) and their alkali metal, polyvalent metal, tertiary amine and quaternary ammonium salts.  Hydroxymethyl pyridazine is prepared by reacting maleic hydrazide with aqueous formaldehyde; it reacts with an alkali metal hydroxide or carbonate, a tertiary amine or a quaternary ammonium hydroxide in aqueous medium at room temperature to form the corresponding salts.  These salts react with solutions of polyvalent metal inorganic salts to form the insoluble polyvalent metal salts of the pyridine derivative.  The preparation of the sodium, potassium, trimethylamine, diethanolamine, triethanolamine and trimethylb -hydroxyethyl ammonium salts is described.  Such salts may also be prepared by reacting the corresponding maleic hydrazide salts with formaldehyde.  Aminomethyl derivatives of pyridazine or salts thereof may be prepared by reacting the hydroxymethyl derivatives or salts with ammonia, a primary or secondary aliphatic or aromatic amine, which may be substituted, or a heterocyclic nitrogen base.  The salts of the aminomethyl derivatives may also be prepared by reacting the aminomethyl derivatives with the appropriate base.  A number of aminomethyl derivatives are listed.ALSO:Growth inhibiting compositions comprise a wetting agent with a hydroxymethyl or animomethyl derivative of maleic hydrazide, or an alkali metal, polyvalent metal, tertiary amine or quaternary ammonium salt thereof. Such compositions are stated to inhibit the sprouting of potatoes, and sucker development of tobacco, and to slow down grass growth.  In examples, compositions containing sodium lauryl sulphate and the dodecylaminomethyl and diethanolaminomethyl derivatives of moleic hydrazide are used to inhibit the growth of tomatoes.
