Title: Method and device for making memory plane for magnetic decoder
IPC: G11C5/12
Filed: 1975-11-25
Abstract: 1504389 Magnetic storage apparatus VYCHISLITEL TSENTR SIBIR OTDEL AKAD NAUK SSSR 25 Nov 1975 48400/75 Heading H3B A magnetic storage matrix is formed by threading apertured ferrite core elements 1 on a common bias wire 3, Fig. 2, separating out the core elements to form storage core pairs 4, 5 with each core consisting of one or more core elements, bending the bias wire intermediate the storage core pair to position the respective core elements in parallel stacks as shown, threading a selection wire 13, Fig. 5, through the pair of storage cores, and repeating the process until a complete row group of core pairs 10, is formed. The process is then repeated to form further row groups of storage core pairs 14, 15, 16 each group being threaded by a respective row wire 5. The row groups are then folded in the convoluted manner shown in Fig. 6 to produce a matrix of storage cores with a separate selection wire 13 threading each column, further selection wires 19 being subsequently added, Fig. 8, by core threading. The matrix is completed by forming an individual winding 22 on each storage core. Assembly may be facilitated by using the Figure shown in Fig. 9 in which a rotatable sprocket has successive stacks of prethreaded core elements 1, each forming a storage core 28, inserted in alternate directions between successive sprocket teeth. The sprocket is rotated to bring the wires into a working position where core threading takes place, the cores being held in position by an arcuate plate 30.

Abstract: 1,047,880. Balancing vehicle wheels. F. O. SKIDMORE. Dec. 1, 1964 [Dec. 6, 1963], No. 48833/64. Heading B7C. A wheel and tyre assembly is balanced by adhesively attaching to a radially inward surface of the wheel rim a malleable metal strip having a weight between 0À2 and 1À32 ounce per lineal inch. Preferably the strip is an extruded lead or lead composition strip 50 (Fig. 6, not shown) having a pressure-sensitive adhesive layer 52 covered, before application to the wheel, by a paper or like layer 54 and divided by grooves 58 into inch-long subdivisions each weighing ¢ ounce. In use, magnetic test weights of the same cross-section and weight per unit length as the strip are applied to the wheel to determine the weight and position required, a corresponding length of strip then being cut off and applied to the rim. In a modification the strip is in the form of a lead band 26a (Figs. 3-5, not shown) tapering from its midpoint to its ends. The adhesive may be applied to the rim before the strip is positioned thereon, or the strip may be suitably shaped and the adhesive then applied to the strip.

Title: Milking machinery
IPC: A01J5/10
Filed: 1962-12-31
Abstract: 986,862. Milking machines; pulsators. U.S. INDUSTRIES Inc. Dec, 31, 1962 [Sept. 26, 1962], No. 49007/62. Heading A1M.  A pulsator for a milking machine comprises two pistons 44-46 and 49-51 which reciprocate alternately in cylinders 9, 10 respectively, the ends 33 and 36 of the cylinders being open to atmosphere. The cylinders are connected by a passage 19, the cylinder 9 being connected through a passage 20 to a source of vacuum and the cylinder 10 being connected through passages 22 and 23 with the teat cup connections 28-31. A milk discharge outlet 64 is constantly under vacuum. A passage 41 is controlled by a slide 56 which is actuated by piston 44-46 and formed with a recess 60 and a deeper recess 59, the slide being mounted on the pulsator casing so that recess 59 is constantly open to atmosphere. With the pistons arranged as in Fig. 6 passage 22, 23 is open to vacuum and chamber 15 is open to atmosphere, the vacuum in cylinder 10 being effective through passage 43, 39 on the front end of cylinder 9. Piston 44-46 therefore moves forwardly thereby moving slide 56 to close passage 41 to atmosphere and open it to vacuum, the resultant vacuum in chamber 15 being communicated to the intermediate part of cylinder 9. Because of the vacuum in chamber 15, piston 49-51 moves rearwardly thereby opening passages 43 and 23 to atmosphere (Fig. 9). In this position atmospheric pressure acts on both ends of piston 44-46 and vacuum on its intermediate part, so that the piston moves rearwardly causing slide 56 to move to open passage 41 to atmosphere. Chamber 15 is therefore open to atmosphere while the intermediate part of piston 49-51 is subjected to vacuum. Therefore piston 49-51 returns to its Fig. 6 position.

Title: Means for producing a Saw-tooth Voltage Waveform
IPC: H03K4/50
Filed: 1967-11-10
Abstract: 1,190,789. Transistor sawtooth circuits. BOLKOW G.m.b.H. 10 Nov., 1967 [19 Nov., 1966], No. 51328/67. Heading H3T. A circuit for producing a sawtooth waveform of constant peak amplitude from trigger pulses of varying frequency comprises a capacitor C11 arranged to charge via a current controlling device (such as transistor T14) the current in which is dependent on the voltage across a further capacitor C10 which is coupled via a gate 3, opened by each trigger pulse, to a source of voltage dependent on the duration of the period between the immediately preceding two trigger pulses. The period (frequency)-dependent voltage is preferably generated by a monostable circuit T4, T5 operated by each trigger pulse. As described, trigger pulses of varying frequency, supplied to terminal H, trigger a monostable blocking oscillator comprising transistor T9 having regenerative feedback via windings n1, n2 of a transformer U. Each pulse from winding n1 triggers a monostable multivibrator T4, T5 which allows a capacitor C6, previously charged via diodes D5, D6, to discharge for a fixed time via a diode D7. The voltage across C6 is thus dependent on the frequency of the trigger pulses at H and is passed via an impedance converter T6 . . . T8 and a link (not shown) between terminals A and B to a gate 3. The gate 3 is opened by the next pulse from winding m3 of transformer U so as to charge capacitor C10 to a voltage dependent on the frequency. This voltage is passed by a further impedance converter 4 and a diode D17 to a transistor T14 which corrects the rate of charge of the sawtooth generating capacitor C11. The next trigger pulse turns on transistor T15 which discharges C11 and completes a single sweep. The sawtooth output is coupled via impedance converting transistors T16 ... T18 to an output terminal C. Modifications.-The link (not shown) between terminals A and B may be omitted so as to introduce a further circuit 6 which provides a further correction for the rate of change of frequency variation of the trigger pulses H. The invention is applicable to determination of the instantaneous positions of rotating bodies (see Division G1).

The products may also be alkylated at the nitrogen atom, to introduce alkyl, oxyalkyl, halogenalkyl, or aminoalkyl groups, and then converted to quaternary ammonium compounds by treating with alkyl halides, dialkyl sulphates or ethylene or other alkylene oxides. The products are intermediates for the production of medicaments and dyestuffs ; they are also useful as textile assistants, for example in vat dyeing. In examples : (1) phenylbiguanide is re-acted with lauryl chloride in toluene in the presence of sodium carbonate to yield 2:4-diimino-5-phenyl- 6-undecyltetrahydro-1:3:5-triazine; the phenylbiguanide may be replaced by methyl-, butyl-, chlorophenyl-, o- or p-toluyl-, anisidyl-, cyclohexyl- and pyridyl-biguanides, or by nitroaryl- or aminoamyl-biguanides, or by amino- and alkylamino-alkyl-biguamides, e.g. diethylaminoethylbiguanide, and the lauryl chloride may be replaced by the chlorides of palm nut fatty acids, or of the fatty acids of blubber or of other fatty acids of naturally occurring fats, oil's and waxes ; (2) phenylbiguanide is similarly re-acted with stearic acid chloride to yield the 5-phenyl- 6-heptadecyl derivative, or with oleic or naphthenic acid chlorides to yield the heptadecenyl or naphthenyl derivatives ; (3) the first-named product of example 2 is sulphonated with oleum ; (4) the first-named product of example 2 is alkylated with dimethyl sulphate and then converted into a quaternary ammonium derivative by further treatment with dimethyl sulphate, or with ethylene oxide or epichlorhydrin ; (5) the product of example 1 is methylated by treatment with dimethyl sulphate ; and (6) phenylbiguanide is re-acted with fencholic acid chloride in toluene in the presence of sodium carbonate and methylated with dimethyl sulphate without isolating the intermediate product; instead of fencholic acid chloride, the bromide or a halide of another acid, e.g. acetic, butyric, valeric, caproic, caprylic or palmitic acid may be used.
