Filed: 1958-10-22
Abstract: 896,155. Digital data-storage apparatus, electrical. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Oct. 21, 1959 [Oct. 22, 1958], No. 33825/58. Class 106 (1). A magnetic drum storage device including arrangement for supervising the cyclic operation of a group of triggers comprises a checking track the output from which is compared with an output derived from a group of triggers which operate in synchronism with the drum, and a device to effect a switching operation (e.g. to give an alarm) in the event of a discrepancy between the two outputs. To check that different clock pulse circuits are functioning correctly the output from a checking track on a magnetic storage drum is compared with an output X obtained, under the control of two programmed triggers MA, MB according to which clock generating circuit is being checked, from suitable combinations of the clock pulses and clock triggers. If a discrepancy occurs between the two outputs a further trigger MAL is operated to give an alarm. Programme equations for the triggers MA, MB and for the output X are given in the Specification. No. circuitry details are given. The invention is mentioned for use in connection with subscriber's meter registering in a telephone system. Specification 810,921 is referred to.

Abstract: 1,227,829. Digital to frequency converters. ROSEMOUNT ENG. CO. Ltd. 10 July, 1969 [17 July, 1968], No. 34028/68. Heading G4H. An apparatus for providing a pulse train having a mean frequency in accordance with a digital input comprises a pulse generator 11, 13, a recycling store 16, and a gate 17 controlling the feeding of pulses from the generator to an output, the gate being controlled by the digit at the output of the store, shifting of the digits in the store being controlled by the circuit 46 which presents each digit at the store output for a number of periods in a given time interval which correspond to its significance. The shift controlling circuit 46 comprises a binary divider 19 producing non-coincident outputs at submultiples of the input frequency on lines 20 to 24 and a counter 25 having outputs 26-30 gated with the divider outputs. The pulses from the generator 31 cause the counter 25 to step round until an output occurs at the " AND " gate corresponding to the divider output whereupon the shift pulses from the high frequency generator 31 are inhibited by the " AND " gate 42. When the next output from the divider occurs the " AND " gates 35-39 are blocked and the gate 42 passes pulses from the generator 31 which shift the data in the store and operate the counter as above. The data in the store is shifted so that the most significant digit is presented at the output for each alternate 100Hz pulse, the next most significant digit each alternate one of the remaining pulses &c. In an embodiment, Fig. 5 (not shown), a delay line replaces the shift register. The data may be stored in pure binary or binary coded decimal and the store output may be monitored, modified and rewritten as desired.

Title: Improvements in coin-freed apparatus for body measurements
IPC: G07F17/04
Filed: 1929-11-12
Abstract: 338,721. Paul, M. Nov. 12, 1929. Measuring-tapes.-A coin-freed apparatus for measuring parts of the body, such as the chest, by a tape, is provided with means for preventing a card which records a series of measurements, leaving the apparatus until the tape has been locked in position. On inserting a coin in the slot 12, the hook 23 is withdrawn from an opening in the metal tape 25. The handle 11 on the shaft 9 is now rotated whereby the slide 5 ejects a card from the pile 3 to a position 3a. To measure the chest, the adjustable casing 2 is raised to a suitable height and the tape 25 on the drum 25a pulled out to the desired length and held in position by the forked hook 32 of the ring 26 attached to the tape, engaging the edge 33 on the casing 2. On depressing the plate 39, a rubber plate 36 presses the raised figure edges of the tape against the card so as to imprint the measurement on the latter. By means of a lever 40 fixed on the shaft 38, the lever 34 is depressed by the pawl 43 whereby the card falls on to the step 34b to bring a second space on the card opposite the tape enabling a second measurement to be recorded. The drum 25a, held in any position by a brake lever 56, is returned to its initial position by a spring mechanism. After three measurements have been recorded the card falls on to a bolt 50 from which it is released by turning a lever on the shaft 51. Simultaneously the hook 23 re-engages the tape to lock it in position. When the next coin is inserted, the lever 34 returns to its original position. A tongue is provided on the edge 33 to engage between the spaced members of the hook 32 to prevent the latter slipping off the edge.

Title: Non-crystallizing syrup of high fermentables content and the process of making same
Inventor: EHRENTHAL IRVING
IPC: C12P19/22
Filed: 1962-09-10
Abstract: The invention comprises a non-crystallizing starch conversion syrup having from 80 to 90% D.S.B. of the carbohydrate materials yeast fermentable and having a dextrose concentration of less than 45% D.S.R.  This syrup may be prepared by microbial enzymic conversion of the product of the malt enzymic conversion of a partially converted starch liquor having a dextrose equivalent below 30. The partially converted starch liquor may be obtained by the acidic conversion of an aqueous starch suspension to a D.E. below 30, preferably 17 to 25, or by conversion of the starch suspension by microbial enzyme(s) to a liquor of 17 to 25 D.E. Alternatively, the starch slurry may be treated directly with the malt enzyme.  The malt enzyme conversion is desirably carried to substantial completion, i.e. to a D.E. of 50 to 55, but the microbial enzyme conversion is halted before the dextrose concentration reaches 45% D.S.B.  Any known commercial malt amylose, either extracted from the malt and added in aqueous solution or added as ground malt, may be used and examples of microbial enzymes are Rhozyme S and 33, Mylase C and SA (Registered Trade Mark) and Hydrolase.  In both enzymatic reactions it is preferred to employ a temperature of 120 DEG  to 130 DEG  C. and a pH of 3 to 7.  The syrups of the invention may be used in the baking, wine, beer and other fermentation industries and in any application where sweeteners are used.

In  a simple embodiment NbTi rods are inserted in a Cu sheath and drawn to form a wire, many of which are stranded together and rolled to form a cable of NbTi filaments in a Cu matrix. The cable is then heated to a temperature which causes a highly resistive layer of CuTi to form round each filament. In the embodiment shown in Fig. 2, NbTi filaments 2 are surrounded by Cu4, Zn 5 and a Cu matrix, and on heating a relatively resistive Cu-Zn layer forms round each filament. In a third embodiment the filaments are surrounded with Al which, on heating, combines with oxygen released from the highly conductive matrix to form insulating aluminium oxide.

Abstract: Drying oils, semi-drying oils, the corresponding fatty acids, and derivatives thereof such as the esters of the fatty acids with mono- or polyhydric alcohols, are catalytically polymerized by passing said materials in a continuous manner through an apparatus comprising a polymerizing zone containing the catalyst and maintained at the polymerizing temperature.  Linseed oil, whale oil, pilchard oil, sardine oil, and linseed oil fatty acid are specified as starting materials, and metallic nickel, platinum, palladium, cobalt, copper and iron, aluminium chloride, stannic tetrachloride, antimony chloride, oxides, inorganic and organic acids, acid salts, and per-compounds are specified as catalysts. The catalyst may be in finely divided or in aggregated form, and may be supported upon a coarsely granular carrier.  The starting material may be treated prior to, or during polymerization, as by oxidation, partial hydrogenation, chlorination or sulphuration, and may be mixed with other materials used in the manufacture of lacquers, varnishes and synthetic resins.  Heat may be recovered from the treated material and used for pre-heating the starting material, and the reaction may be effected in vacuo, at ordinary or increased pressure, or in such gases as carbon-dioxide or nitrogen.  According to examples, a continuous stream of linseed oil, of heated oxidized sardine oil, or of heated linseed oil fatty acid, is passed through a heated tube filled with activated nickel.  The polymerizing process may be followed by distillation in vacuo, steam distillation, molecular distillation, or by a combination of such treatments.
