Title: Improvements in or relating to apparatus for converting electrical analog input current or voltage into digital form
IPC: H03M1/00
Filed: 1958-05-06
Abstract: 869,262. Electric selective-signalling Systems. DAYSTROM Inc. May 6, 1958 [May 8, 1957], No. 14504/58. Class 40 (1). In an analogue to digital converter an unknown current I, Fig. 1, is applied to the input of an integrator tending to cause its output potential e, Fig. 2, to rise, and a reference current of opposite polarity is repeatedly applied to to the integrator input every T 0  seconds (see Fig. 2), and is maintained applied until the output potential e drops to zero. The period of time T 1  for which the reference current has to be applied is proportional to the magnitude of the unknown current I or if it varies to its average value and is measured by counting the number of clock pulses that are produced by an oscillator and a 1 : 4 frequency divider. The counter is reset at the end of each period T 0 . The same oscillator together with a 1 : 200,000 frequency divider determines the periods T 0  at the beginning of each of which a flip-flop is turned on (to apply the reference current I 0  to the integrator and to admit clock pulses to the counter) the flip-flop being turned off when the integrator output reaches zero. Specifications 749,251 and 848,140 are referred to.

Title: Improvements in machines for testing materials under repeated stresses
IPC: G01N3/32
Filed: 1924-06-20
Abstract: 232,905. Amsler, A. April 23, 1924, [Convention date]. Testing physical qualities of materials.-Comprises a device for carrying out fatigue tests by subjecting a test piece to repeated blows of the same impact until the test piece is fractured, such blows being independent of the weight of the hammer producing them. A hammer 1, Figs. 2 and 3, moving in guides 1<1> is provided with a traverse 3 with the lower face of which co-operate rollers 4, 5 on a disc 6 which in effect forms a double crank. The disc 6 is located between a collar 7 and a disc 8 on the shaft 10 acted upon by a spring 9 the tension of which is adjusted by a unit 9<1>. To the driving shaft 10 on which the fly-wheel 11 is mounted, a uniform rotation is imparted. Springs 12, 13 fixed at one end and attached at the other end to the part 3 pull the latter down into contact with one or other of the rollers 4, 5 so that the hammer follows the roller that moves away from the hammer. By a suitable dimensioning of the parts, the test piece, which in one form is placed under a bending test, is struck by the hammer following up one of the crank pins immediately after the hammer has attained its maximum speed. When a rupture of the test piece occurs or when the latter is deflected beyond a predetermined amount, the hammer abuts against a stop 15 which limits its downward stroke whereupon a device is actuated which secures the hammer in the upper position and puts it out of action. A counter 16 registers the number of impacts. -To submit a specimen to repeated tensile stresses, the part 23 engages a sleeve 19 screwed to the lower end of the test piece whilst a similar sleeve 20 screwed to the upper end rests in the top portion of the frame as shown in Fig. 4.

Patent GB-475723-A (GB)
Title: Improvements relating to the refining of hydrocarbon oils
IPC: C07D295/023
Filed: 1936-05-21
Abstract: Hydrocarbon oils are freed from asphalt, unsaturated or aromatic constituents by treatment with a liquefied normally gaseous fluorine compound.  Dichlordifluormethane is excluded. The selective solvent property of aliphatic fluorinated compounds increases with the number of fluorine atoms present.  The introduction of fluorine into hydrocarbons containing other halogens increase the selectivity property when the number of fluorine atoms equals or exceeds the atoms of other halogens. Selective solvents are, mono-, di-, or tri-fluormethane, carbon tetrafluoride, monoto hexafluorethane, monofluorethylene, monochlormonofluormethane, monobromtrifluorethane, or dichlortetrafluorethane.  Non - selective solvents are dichlormonofluormethane and corresponding gaseous compounds of ethane propane, propylene, or ethylene.  Asphalt is first removed at an elevated temperature in the presence of a non-selective solvent, and after chilling to remove wax if present, is then treated with a selective solvent to form raffinate and extract layers which are separated.  The selective solvents may be admixed with other selective solvents such as phenol, furfurl or sulphur dioxide or with diluents such as non-selective fluorinated compounds, alcohol or, in some cases, water.  The non-selective selective solvents may be used as diluents for a sulphuric acid treatment applied after separating asphalt and before de-waxing. Specifications 373,538 and 474,464, are referred to.
