Title: Associative memory system
IPC: G11C15/02
Filed: 1969-02-19
Abstract: 1,207,105. Data storage. NATIONAL CASH REGISTER CO. 19 Feb., 1969 [21 Feb., 1968], No. 9088/69. Heading G4C. [Also in Division H3] An associative store includes a plurality of electrically-conductive rod-like structures, each having a plurality of bi-stable thin magnetic film non-destructive read-out storage elements spaced therealong to store respective bits of a word, the relative magnitude or equality of a descriptor word as compared with each of he stored words being determined by applying the bits of the descriptor word in turn for comparison with respective bits of each stored word, each bit comparison producing a pulse of one polarity, a pulse of the other polarity, or no pulse, in a respective word sense line according as the stored bit is greater than, less than or equal to the descriptor bit. Each rod is a conductor coated with a magnetic storage film (isotropic) coated with a non-magnetic (conducting) film coated with a magnetic read film (axiallyoriented anisotropic). A word winding is wrapped around the read film, and at each bit position a bit winding is wrapped around the word winding. A word is cleared by pulsing the word winding. After clearing, a word can be written by pulsing the word winding in conjunction with a pulse on those bit windings at positions where a 1 is to be written. Non- destructive read-out is on the bit windings by pulsing the word winding. Associative matching is by applying the descriptor word to the bit windings, using a negative pulse, a positive pulse and no pulse to represent 1, 0 and a masked-out bit respectively. All the pulses start together but end progressively later for successively lower binary orders, the trailing edge of a pulse producing in the conductor (at the centre of the rod) a positive pulse, negative pulse or no pulse according as the descriptor bit is less than, more than or equal to the stored bit respectively. The first pulse, if any, on a given rod conductor, sets one of two respective flipflops (which were initially reset) according to the pulse polarity. After the full comparison, those stored words equal to, less than or more than the descriptor word, as selected by an associated computer, are read out in turn.

Title: Bottle washing machines
Inventor: MOORES EDMUND ROY
IPC: B08B9/44
Filed: 1956-03-23
Abstract: 803,351. Washing bottles. GIMSON & CO. (LEICESTER), Ltd. Jan. 31. 1957 [March 23, 1956], No. 9168/56. Addition to 654,905. Class 138(1). [Also in Group XXX] The bottle washing machine of the parent Specification includes in the bottle-feed means an actuating linkage which has a connection consisting of two spring-biased parts 98, 100, the spring 108 being so adjusted that the two parts move relatively to each other only when the feed means encounters abnormal resistance, this relative movement serving to operate an electric switch 112 to stop the machine. As shown, the rod 31 has a reduced extension 96 sliding in the socket 98 threaded to take the sleeve 100 having adjusting head 102 and lock-nut 104. Rod 96 has an enlarged head 106 between which and the sleeve 100 is a spring 108 adjustable by means of the head 102 to give a pressure greater than the normal operating load in tension rod 31 so as to prevent relative movement between parts 98 and 100 in normal operation. Abnormal resistance to feeder bar 33 however, results in extension of spring 108 and relative motion between parts 98 and 100, as well as separation of the mushroom-shaped head 120 from the micro-switch 112 which stops the main motor drive and therefore the movement of bar 33.

Filed: 1927-04-04
Abstract: 269,522. I. G. Farbenindustrie Akt.- Ges. April 15, 1926, [Convention date]. Azo dyes, soluble chromium compounds of.- Chromium compounds of azo dyestuffs are made by treating dyestuffs containing chromable groups with salts of trivalent chromium, the chromium salts being employed in such proportions as to provide less than one atom of chromium for each chromable group in the dyestuff molecule. The products differ in their tinctorial properties from those made from the same parent dyestuffs with larger amounts of chromium salt. The reaction may be effected by the known methods, with or without pressure; soluble salts may also be added as described in Specification 262,418. In examples, dyestuffs containing two atoms of chromium to three molecules of dyestuff are made (1) by heating the dyestuff from diazotized 4-chlor-2-aminophenol-5-sulphonic acid and 1- phenyl-3-methyl-5-pyrazolone with chromium hydroxide and formic acid under pressure; the sodium salt of the resulting chromium compound dyes wool in an acid bath a pure red, whereas the corresponding dyestuff prepared with larger amounts of chromium, and containing one atom of chromium to each molecule of dyestuff, gives yellowish-red shades, and (2) the dyestuff from diazotized 4-nitro-2-aminophenol-6-suphonic acid and /3-naphthol is boiled under reflux with chromium formate solution; the product dyes wool black, whereas the corresponding dyestuff with one atom of chromium in each molecule of dyestuff gives a violet-brown shade.

Title: Improved process relating to the manufacture of guanidine and derivatives thereof
Inventor: ROBERTS ELWYN
Filed: 1952-04-10
Abstract: Guanidinium alkyl sulphates are made by causing urea to react with a dialkyl sulphate, removing residual excess of the dialkyl sulphate and then aminating the O-alkyl isourea compound with ammonia.  The excess dialkyl sulphate may be removed by heating with water to form an alkyl hydrogen sulphate and an alcohol.  In an example urea is caused to react with diethyl sulphate, the product is heated to about 80 DEG  C. for an hour and then ammonia is added for the amination. The guanidinium alkyl sulphate may be hydrolysed with dilute sulphuric acid to yield guanidinium hydrogen sulphate from which guanidine or a guanidine derivative may be obtained.  Specification 817,748 is referred to.

Title: Method and means for determining optimum current strength in the electro deposition of rubber and other substances
IPC: C25D13/22
Filed: 1927-04-06
Abstract: 293,343. Dunlop Rubber Co., Ltd., and Lane, F. H. April 6, 1927. Drawings to Specification. Latex, treating.-A means for determining the current density necessary for the electrophoretic deposition of rubber or the like havmg given characteristics consists in the use of a test anode mounted so as to bear a varying current density along its length and therefore a deposit of varying character; the anode may be provided with a scale indicating the current density at each point. The anode may consist of a vertical zinc plate forming one side of an ebonite box, and the cathode of a vertical bar mounted near one end of the plate. The scale may be calibrated on the assumption that the thickness of the deposit at each point is proportional to the current density. Calibration may be facilitated by connecting the test cell in series with an ammeter and another cell having cylindrical electrodes mounted so as to exhibit uniform current density and comparing the thickness of deposit in the two cells. The invention may be applied to deposition from natural or artificial vulcanized or unvulcanized dispersions of rubber containing any of the usual compounding ingredients.
