Abstract: 656,211. Speed governors. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Oct. 11, 1948, No. 26407. Convention date, Oct. 11, 1947. [Class 57] [Also in Groups. XIX and XXIX] A speed responsive device for indicating, recording or controlling speed comprises a centrifugal flyweight mechanism having a member movable along the axis of rotation by the centrifugal force in opposition to the internal pressure of a pneumatic bellows which is supplied with pneumatic fluid through a duct provided with a discharge orifice the discharge of fluid from which is controlled by the position of the member. The centrifugal mechanism comprises a pair of flyweights 7 adjustably mounted on threaded rods pivoted on a carrier 4 driven directly or through gearing from the machine unless speed is to be indicated or controlled. A vertical member or tube 11 movable by the flyweights is connected at 18 to a lever 17 pivoted through a leaf spring 19 to a stationary frame F. Air is supplied to the bellows 20 through a supply conduit 27, relay valve 35, and conduits 36, 24. The latter communicate through a conduit 37 with the device for indicating or controlling the speed, e.g. a pressure gauge 38 calibrated in terms of speed. Supply conduit 27 has a branch 28, provided with a constriction 29, leading to a nozzle 25 whose discharge is more or less baffled by the lever 17 so as to vary the air pressure in the branch 28 which communicates with a bellows 30 controlling the relay valve 35. The latter has a pair of valve members 34, 33 controlling respectively the supply and exhaust of air in the conduit 36. In another embodiment the relay valve is omitted and the supply conduit 27 is connected through an adjustable throttle valve with the bellows and with the nozzle 25. In another embodiment the nozzle is omitted and the end of lever 17 actuates a combined supply and exhaust valve in the supply conduit leading to the bellows. The static weight of the centrifugal mechanism may be balanced by a spring, 15 so that the pressure in conduit 24 varies substantially as the square of the speed.

The graduation marks on glass measuring instruments, e.g. cylinders, pipettes, burettes, are applied by a screen-printing process utilizing a stencil which is adjustable in length. The fixed points, e.g. " 0 " and " 100 " millilitres or degrees, on such instruments may thus be evenly divided irrespective of whether the internal dimensions of any one instrument differs from the others as the stencil may be expanded or contracted to effect the alignment of the fixed points on both stencil and instrument prior to stencilling. The stencil may be of a thermoplastic material or rubber and, as shown in Fig. 1, a measuring cylinder is printed with even divisions between 0 and 500 by using a stencil 3 in which the fixed points are aligned by expansion or contraction. Fig. 2 shows a resiliently expansible stencil 12 fixed at one end to a frame 13 and at the other to a manually - rotatable pawl-and-ratchet controlled roller 11 by which the stencil is stretched such that the reference points 16 of the stencil is varied in accordance with the distance of the points 17 of the markings to be applied to the glass instrument 15. By fixing the stencil to the frame 13 at an intermediate point 21 the stretching or contracting of the stencil can be confined to the portion on the left of said point.

Title: Process and apparatus for producing emulsions from fatty materials
IPC: A23D7/02
Filed: 1927-10-12
Abstract: 304,256. Potts, H. E., (Faurskov, V. A. T.). Oct. 12, 1927. Emulsions, making. -Fatty materials are formed into emulsions, e.g. margarine. chocolate pulp, or tallow, by whirling in a groove between two cylindrical surfaces revolving in opposite directions with a peripheral velocity of not less than 30 metres per minute, and a very thin layer of material is subjected to high pressure on passing through the very small gap between the cylinders, and constantly removed. The peripheral velocity of the revolving surfaces is usually 70-200 metres per minute, and at 160 metres per minutes and a gap of 0.1 m.m., the material is subjected to 500 kgms. pressure per sq. cm. The thin material is removed by scrapers or by cooler surfaces preferably revolving under high pressure against the cylinders. Several cylinders may be arranged in series, e.g. materials fed at 12 to cylinders 1, 2 are transferred to cylinders 3, 4 of equal or differing peripheral velocities, scrapers 5, 5' removing the product. Cooling or heating agents are introduced into the cylinders, which have hollow shafts and interiors and end flanges 13 or stationary walls. Margarine is thus obtained from its constituents without further treatment, e.g. by feeding the materials at 100 gms. per second at 25‹ C. to cylinders 6, 7, 8 as shown and with respective temperatures 11‹, 9‹, 7‹ C., and a peripheral velocity of about 165 metres per minute. Hydrogenized hard fats so treated become plastic.

Title: Process for the manufacture of cyclic ketones
IPC: C07C45/58
Filed: 1931-09-28
Abstract: Cyclic ketones are manufactured by heating the oxides of cyclic olefines, if desired in the presence of catalysts of the group comprising surface catalysts, such as pumice or silica gel, acid or neutral metal salts, such as magnesium sulphate or cupric pyrophosphate, which may be deposited on surface catalysts, and heavy metals, such as nickel.  The starting materials are obtainable from cyclic olefines, for example by the action of per-acids.  In examples: (1) 3-menthene oxide is heated with silica gel to 250 DEG C. yielding 3-menthone; (2) cyclohexene oxide is distilled over magnesium sulphate on pumice, heated to 230-250 DEG  C., to produce cyclohexanone; (3) 1-menthene oxide is heated to 250-280 DEG  C. with cupric pyrophosphate, producing carvomenthone; (4) 3-menthene oxide is heated alone to 250-280 DEG  C. yielding menthone.  Other starting materials specified are the oxides of methylcyclohexenes, e.g. 1-methylcyclohexene-3, and of camphene.

Abstract: 1,058,270. Cathode-ray tube circuits. MOTOROLA Inc. June 30, 1964 [Aug. 1, 1963], No. 27023/64. Heading H4T. Relates to a vertical dynamic convergence arrangement for a colour picture cathode-ray tube, a convergence coil being energized from a source of vertical beam deflection sawtooth signals so as to develop signals of parabolic waveform in the coil by integration. According to the present invention the sawtooth signals are clipped and thereafter introduced into the convergence coil. It is stated that inherent resistance in a convergence coil inhibits complete integration, and hence correct dynamic convergence, with known arrangements. The embodiment is for a " shadow mask " three-gun colour television receiver picture tube, the corresponding vertical convergence coil sets (12a, 14a, 16a, Fig. 1) influencing respective ones of the three beams at the field rate, the horizontal convergence coils (12b, 14b, 16b) receiving approximately parabolic signals from a low-impedance resonant circuit in known manner. The vertical convergence coils are fed from auxiliary windings (24, 26) on the vertical deflection output transformer (22) and a series resistance path provided by two potentiometers (40, 42) in conjunction with the inductance of the coils affords integration of the sawtooth wave across a resistor (21) in the cathode circuit of the vertical deflection output valve (20) into a parabolic wave. To neutralize the effect of resistance in the convergence coils a diode-resistor path (50, 52) in parallel with the two potentiometers clips adjustable negative portions off that sawtooth wave (Fig. 3, not shown). Another embodiment utilizes two diode-resistor clipping circuits one of which is in parallel with theseries combination of the " red " and " green " vertical convergence coils and the other of which is in parallel with the " blue " convergence coils (Fig. 2, not shown).
