Title: A temporary storage for an electronic computer
IPC: G06Q30/00
Filed: 1965-07-23
Abstract: 1,087,406. Electric digital calculators. FRIDEN Inc. July 23, 1965 [July 24, 1964], No. 31593/65. Heading G4A. A device for aiding computer calculations comprises two temporary storage registers R1, R2 and a number of additional registers RS1- RSn, two of which registers, comprising at least one of said temporary storage registers, are selectively co-operative with one another as active and passive registers respectively in order to carry out wanted calculations, and a circuit FF1, FF2 selecting the two registers in accordance with orders from the computer, determining which of the two registers is active or passive and interchanging the active and passive registers prior to the entry of a number into one of the co-operating registers. As shown, the registers are selected by two flipflops FF1, FF2. FF1 has one output coupled to AND gate 27 and the other to AND gate 28 while FF2 has one output 25 coupled to AND gates 27, 28 and the other, 26, to AND gates 29-34, each of the gates being coupled to a separate register. If the output of FF2 is on line 25 then FF1 determines which of the gates 27, 28 is enabled and thus which register is active, the other register being passive. If the output of FF2 is on line 26, then selector 11 determines which of the gates 29-34 is enabled and hence which one of registers RS1-n is active, the passive register in this case being determined by the output of FF1. If this is on line 23 then R1 is the passive register, if on 24 then R2 is the passive register. During the operations numbers to be stored are always entered into the active register and numbers required for arithmetic operation are always taken from the active and the passive registers. Before an operation a pulse on line 22 switches the output of FF2 to line 26. Assuming that R1 is the active register at this stage and a number is to be stored, a pulse on line P1 renders R2 active and the number (a) is entered therein. A further pulse on P1 renders R1 active and a second number (b) is entered. An instruction, such as multiply, then causes both numbers to enter the arithmetic section, to be operated on and to be returned to the active register R1. A further instruction multiply causes number (abc) to be entered in R2. A further instruction subtract can then enable calculation gross amount minus discount ab - abc to be performed.

Title: Percussion fuzes for projectiles
IPC: F42C15/26
Filed: 1935-11-19
Abstract: 454,339. Projectile fuzes. BIRKIGT, M., Rue du Capitaine Guynemer, Bois-Colombes, Seine, France. Nov. 19, 1935, No. 32071. Convention date, Oct. 14. [Class 9 (i)] Relates to percussion fuzes of the kind in which the striker is locked by centrifugal members normally kept in place by means of two rings which set back by inertia when the projectile is discharged, one remaining rearwards and the other returning forwards after acceleration is over to release the centrifugal members. According to the invention the second ring begins its return forward movement by virtue of its momentum while the projectile is decelerating and this forward movement is completed by the same cause which may, however, be helped by the centrifugal force of the centrifugal members. In the form shown, the striker 7, which has a head 13 behind a lid 15, bears with a flange 10 on balls 11 resting on a seat 8 surrounded by two rings 9, 12. The ring 9 is split and makes a friction grip with the wall of the fuze body 14. The ring 12 is loose. When the projectile is discharged both rings set back. When acceleration is over and projectile begins to lose speed, ring 9 remains behind, but ring 12 creeps forward by virtue of its momentum. After this creep has started, a conical flare 17 on the ring comes opposite the balls 11, which move out by centrifugal force to release the striker, this centrifugal force helping to complete the forward movement of the ring 12. An accidental check to the projectile before the arming operation is completed causes the rear ring 9 to move forward with the ring 12 and lock the balls in the safe position.

Title: Improvements in or relating to the manufacture of ammunition cartridges
IPC: F42B33/04
Filed: 1945-11-30
Abstract: 604,718. Cartridge capping machines. VINCENT, M. Nov. 30, 1945, No. 32487. [Class 9 (i)] A machine for inserting percussion caps in ammunition cartridge cases has a slidable feed member 22, Fig. 3, which conveys one case at a time into axial alignment with a reciprocating ram 7, Fig. 1, which removes the case from the member 22 and carries it into engagement with capping means, the feed member having a spring-loaded flap 27 which holds each case in place but which is opened to release each case when the latter is caught by the ram and the feed member then retracted. As shown, the cases are fed down a shoot 15 and pass one at a time into the space between arms 23 of the feed member and the flap 27. The feed member is reciprocated by an arm 32 which is moved in one direction by a spring 41 and in the other direction by a cam 42 on a driven shaft 43. When the spring moves the feed member to align a case with the ram 7 the latter is moved by a crosshead 6 into the case to hold it, and the feed member is then withdrawn leaving the case on the ram. The ram is urged by a spring 13 against a nut 12 which screws into a sleeve 9 adjustably mounted in the crosshead. The percussion caps are fed from an agitated overhead hopper formed by two plates spaced apart by a distance slightly greater than the lengths of the caps, and pass into a vertical channel 52 in a single column and thence to a radial groove in a cylindrical block 60. This block is screwed on to a sleeve 61 containing a capping punch 62 which is reciprocated by a pivoted lever 67 driven by a cam 68 on shaft 43. Under the action of the cam 68 the punch 62 pushes each cap along an axial bore 66 as the ram 7 carries a cartridge case towards this head and the cap is thus forced into position. When ram 7 is retracted the case is removed from it by a plate 77 and the cap drops down a shoot 80 on to a grill 81, the function of which is to allow any caps which have been jolted from their cases to pass down a shoot 85 to a receptacle.

Title: Process of purifying glycerine distillates obtained from fermentation liquors
IPC: C12P7/20
Filed: 1932-11-17
Abstract: Dynamite glycerine is obtained from fermentation glycerol liquors, e.g. the glycerol liquor distilled from the alkaline fermentation of sugar, by making the liquor alkaline with an alkaline earth base, blowing with air to destroy phenolic impurities, boiling to remove volatile nitrogen compounds, precipitating the earth base, and distilling off the glycerol. The product may be decolorized with carbon with or without a siliceous filtering agent.  In an example, molasses is fermented in known manner in presence of alkalies or salts; glycerol liquor is distilled from the concentrated and dealcoholized slop, preferably by superheated steam in vacuo in countercurrent to the atomized slop as described in U.S.A. Specification 1,627,040; 40 gm. of slaked lime per 4 litres of distillate is added, air is blown through the mixture for 4 hours, and the mixture is boiled for 3 hours, allowed to cool, and is filtered; the filtrate is made faintly acid by passing in carbon dioxide, boiled for 15 min., and filtered to remove calcium carbonate; the liquor is concentrated in vacuo to 80 per cent glycerol, distilled at 20 m.m. and 180 DEG  C. with superheated steam, and fractionally condensed, the receivers being at 125 DEG  C. and 65 DEG  C. respectively. The glycerol in the first receiver is decolorized at 100 DEG  C. by 2 per cent of carbon.

Title: Improvements in or relating to synthetic dicarboxylic acid esters, lubricants and process for their preparation
IPC: C07C51/27
Filed: 1952-12-30
Abstract: A mixture of di-esters or complex esters of dibasic acids having 8 to 14 carbon atoms in each acid molecule is prepared by sulphating oleic acid, hydrolysing the resultant sulphate to a mixture of hydroxy stearic acids, cleaving the mixed acids by nitric acid oxidation to form a mixture of dibasic acids and recovering and fully esterifying the mixed acids with an aliphatic alcohol containing 6 or more but preferably less than 21 carbon atoms or partially esterifying the mixed acids with such an alcohol to form a half-ester with which a glycol is fully esterified.  In an example, oleic acid in hexane solution is sulphated with sulphuric acid at 0 DEG  to -10 DEG  C., the resulting sulphate is hydrolysed by boiling with water yielding a mixture of hydroxy stearic acids containing some esters which is saponified and distilled to remove liberated alcohol; the residue is acidified and the hydroxy stearic acids recovered therefrom; the mixed acids are then added to boiling nitric acid containing ammonium metavanadate as catalyst and the dibasic acids formed are recovered by boiling off the excess nitric acid and then fully esterified with iso-octyl alcohol.  In forming complex esters there may be used as the glycol, ethylene glycol, polyethylene glycol or thiodiglycol. The esters and complex esters may be used as lubricants.ALSO:A lubricating composition comprises a mixture of di-esters or complex esters of dibasic acids, having 8 to 14 carbon atoms in each acid molecule, prepared by sulphating oleic acid, hydrolysing the resultant sulphate to a mixture of hydroxy stearic acids, cleaving the mixed acids by nitric acid oxidation to form a mixture of dibasic acids and recovering and fully esterifying the mixed acids with an aliphatic alcohol containing 6 or more but preferably less than 21 carbon atoms or partially esterifying the mixed acids with such an alcohol to form a half-ester with which a glycol is fully esterified.

Title: Brake mechanism
IPC: F16D65/14
Filed: 1946-11-07
Abstract: 651,195. Fluid pressure disc brakes; automatic adjustment to compensate for wear. WINGFOOT CORPORATION. Nov. 7, 1946, No. 33096. Convention date, April 16. [Class 103 (i)] In a brake of the type in which blocks 19, 23 (Fig. 2), of friction material are clamped for braking against opposite faces of a rotating disc 21 by a hydraulic piston and cylinder device 29, 24 and in which the release position of the piston 29 is automatically adjusted to compensate for wear of the friction blocks, the piston and cylinder device is supported resiliently from a fixed bracket by means which are also automatically adjusted to compensate for wear of the friction blocks. The cylinder 24 comprises members 13 and 14 fitted together at 14a and secured by cap screws 13a. The piston 29 is normally withdrawn by a conical spring 36a secured at its periphery to the piston and abutting against a disc 32 engaging the head of a pin 33 which serves as an abutment for the piston in its release position. The pin 33 is held by a deformable ring 37 compressed by a nut 35 ; if owing to wear of the blocks 19, 23 the force in the spring 36a rises abnormally during braking the pin 33 is pulled through the ring 37 to effect the necessary adjustment. The members 13, 14 carry at each side lugs 13b, 14b (Fig. 3), connected by a bolt 15. On each bolt 15 is mounted a sleeve 38 sliding within a boss 16 formed on a flange 11 supporting the braking means. A collar 43 is mounted on a reduced portion 39 of the sleeve 38 and between the collar 43 and the sleeve 38 are mounted rings 41 comprising split washer-like members whose radial thickness decreases towards the split and which, while remaining circular, tend to expand into frictional engagement with the boss 16. Conical spring 42 abutting the rings 41 and the collars 43 normally permit movement of the lugs 13b, 14b, and thus of the members 13 and 14, relatively to the bosses 16 ; if however, owing to wear of the friction blocks 19, 23, the force in the springs 42 rises abnormally during braking the frictional grip of the rings 41 on the bosses 16 is overcome and the members 13, 14 are permanently adjusted relatively to the bosses. Sealing means 44a, 44b (Fig. 3), and 45, 46 (Fig. 2), exclude entry of dirt or leakage of pressure fluid. Specification 583,596 is referred to.
