Abstract: 909,531. Grinding. CIMAT COSTRUZIONI ITALIANE MACCHINE ATTREZZI TORINO S.p.A. July 27, 1960 [Aug. 6, 1959], No. 26178/60. Class 60. [Also in Group XXII] In a grinding machine having a grinding wheel 4 driven by an electric motor 2, a circuit providing a higher rate of feed of the workpiece before engagement thereof with the grinding wheel comprises a capacitor 24 which is changed to a voltage dependent on the no-load current of the driving motor and which blocks a valve 27 and a. series resistor 26 which is fed with another voltage in opposition, also dependent on the motor current, which overcomes the capacitor voltage and fires the valve, reducing the feed rate when the motor current increases due to engagement of the grinding wheel and workpiece. In a 3-phase system, the motor current is measured/rectified and smoothed by current transformers 12-14, diodes 18-20 and a capacitor 21, and applied to a storage capacitor 24. Before contact of the grinding wheel and the workpiece, a switch 23a, 23b disconnects the capacitor 24 and connects a resistor 26, the voltage across which increases with the motor current, overcon es the voltage across the capacitor 26 and fires a thyratron 27, which reduces through an electromagnetic valve 11 the oil flow to an hydraulic ram 9, 10 feeding the slide 5 on which the worktable 7 reciprocates. In a D.C. system, the motor current is measured by a resistor in series with the supply.

Title: Improvements in or relating to rust preventive fuel compositions
IPC: C10L1/30
Filed: 1949-10-13
Abstract: A motor fuel, e.g. gasoline, containing a partial ester formed from a polyhydroxy alcohol and at least one monocarboxylic acid, and which may or may not contain tetraethyl lead and an organic halide scavenging agent, is burnt in an internal combustion engine, in which a motor fuel containing tetraethyl lead and an organic halide scavenging agent has been burnt, prior to a period of idleness of the engine.  Rusting of the internal surfaces of the engine is thus inhibited.  Polyhydroxy alcohols mentioned are pentaerythritol, dipentaerythritol, erythritol, polyglycerol, sorbitol, polysorbitol, sorbitan and mannitol.  Monocarboxylic acids specified are those having 8-24 carbon atoms, such as oleic, lauric, caprylic, palmitic, myristic, stearic and capric acids. From 0.01 per cent to 1 per cent of the ester may be added to the fuel.  In an example, an aviation fuel containing tetraethyl lead and ethylene dibromide, with an addition of 0.5 per cent pentaerythritol monooleate, is compared with a similar fuel containing pentaerythritol tetraoleate.

Abstract: A plaster of Paris bandage is made by enclosing plaster in a tube of gauze fabric, the cross-section of which may be circular, rectangular or in the form of a number of tubes adjacent to each other.  The gauze is of such size, preferably 18 threads per centimetre in each direction, that it retains the plaster but does not interfere with its being thoroughly wetted.  When the bandage is applied with the surfaces of the adjacent turns closely and firmly pressed together, the plaster adheres to itself through the meshes of the gauze and forms a strong, rigid mass.

Abstract: 1275045 Measuring small objects SIRA INSTITUTE 5 Sept 1969 [5 June 1968] 26875/68 Heading G1A [Also in Divisions G2-3] To measure a dimension of an object, such as the width of an aperture 2, radiation from a source 1 e.g. a laser is directed at the object and the resulting diffraction or interference pattern formed at a slit 4 is focused on to a rotating radial transmission grating 6, the resulting light signal received at a detector 8 through a diffusing screen 7 being at least part of a Fourier transform response of the intensity distribution in the scanned diffraction pattern image. The axis of the slit 4 is perpendicular to that of the aperture 2 and the grating axis 16 is movable relative to optic axis 17 to provide different scanning spatial frequencies. By measuring the output of the photo-detector, using an instrument 13, at two or more scanning frequencies and extrapolating to zero detector output, the width of the aperture may be determined, since this width is proportional to the spatial frequency at zero detector output Fig. 3 (not shown). Alternatively, readings taken at various spatial frequencies may be compared with readings obtained from a standard object in a gauging process. The apparatus may be designed to operate automatically and reject articles outside a given tolerance. Units 8, 11, 12 and 13 of the detector circuit may be interchanged with an incoherent source of light 1 so as to scan the radiation beam before the diffraction pattern is formed.

Abstract: 672,614. Glass. VAPOR HEATING CORPORATION. Nov. 3, 1950 [Feb. 25, 1950], No. 26924/50. Class 56. The liquid in a thermometer tube is pressurized by supporting the tube intermediate its ends, sealed end up, within a resilient clamping ring 34. The sealed end projects into a chamber 40 containing a gas, e.g. hydrogen, under pressure, and the other end projects into a chamber 74 containing an inert gas, e.g. nitrogen, under a pressure greater than that in the chamber 40. The sealed tip of the tube is now broken off by releasing a rod 52 acted on by a spring 60 and the hydrogen is thus admitted to the bore under pressure. A portion of the tube subjected to the higher nitrogen pressure is now locally heated by a heater 72 until it becomes plastic; the higher gaseous pressure in conjunction with the weight of the tube and the liquid therein causes the softened glass to collapse and reseal the tube at the locally heated point.

Recording-apparatus comprises a stylus moved relative to a chart in a generally spiral path in response to current variations in a moving coil element 1 and, connected to control mechanism, a switching circuit which imposes, on the normal current supply to the element 1 a further momentary current supply when the control mechanism is operated. In a hoist tachograph the coil 1 is made responsive to the output of a tachogenerator 7 and actuation of a brake lever to ON and OFF positions moves a switch arm 10 on to a contact 12 or 11, causing a condenser 26 to charge positively or negatively and -upon discharge to energize a relay 29 or 30, thus selecting condenser 8 or 9 to be charged. The selected condenser discharges through the coil 1 in a direction determined by the setting of a switch 16 to produce a shorter line 13 or longer line 14 according to the capacity of the condenser 8 or 9 selected and deviating from the normal graph 15 on one side or the other according to the setting of the switch 16 The switch 16 is set by a relay 17 in accordance with the state of a switch 18 which in turn is operated by a hoist control lever through cam and follower mechanism described with reference to Figs. 2 to 6 and Figs. 8 to 12 (not shown). An A.C. supply may be superimposed on the normal supply to the moving coil 1 causing vibration of the stylus resulting in a thickening of the line traced thereby thus another indication can be given by connecting or disconnecting the A.C. supply.
