Abstract: 1,062,209. Grinding apparatus. W. SIMON. Oct. 13, 1965, No. 43452/65. Heading B2A. Grinding apparatus comprises a rotor 1, Fig. 1, provided with annular shelves 4 to the upper and lower sides of which are detachably secured interchangeable U-shaped metal tools 5 with partition discs 2 provided between two adjacent shelves. The rotor is arranged for rotation in a ridged casing (9, Fig. 3), the discs 2 dividing the casing into partitions. Orifices (8, Fig. 2) are provided in the U-shaped tools adjacent their working edges (7). The air gap between the tools and casing is adjusted by rotation of a counter ring (11) which contacts a threaded flange (10) on the casing (9) so that the casing may be raised or lowered axially relative to the rotor. Grinding takes place in the gap as a result of a head of pressure between the external edges (7) and the ridges of the casing and also due to air flow through the orifices.

Abstract: 1480277 Measuring liquid metal levels MINE SAFETY APPLIANCES CO 9 Oct 1974 [10 Jan 1974] 43793/74 Heading GIN [Also in Division G4] Temperature effects in a coupled coil liquid metal level detector are compensated for using a non-linear function generator. Primary winding 18 of high resistance and high temperature coefficient of resistivity wire and inherent resistance 28 is fed with constant alternating current over transformer 34 from operational amplifier 38. The potential drop across coil 18 mainly due to the resistive component of the coil is obtained from terminals P and converted by detector 43 to a D.C. signal T s  which thus varies as a function of coil temperature. Secondary coil 20 and its inherent resistance 30 is connected to the inputs of operational amplifier 44 to furnish an output which is a function of liquid level, uncompensated, and which is converted by detector 45 to a D.C. signal L s . A non-linear transfer function f(T s , L s ) is then synthesized electronically either digitally by converting the signals T s , L s  to digital signals or by analog signals processing. Details of such an analogue process are described Figs. 3, 4 (not shown), see Division G4, using a series of potentiometers and multipliers, the values of the potentiometers determining the coefficents in the transfer function and being determined by measuring and tabulating T s , L s  and processed on a digital computer using well known curve fitting techniques. A third variable representing time could also be used to correct for time dependent effects.

A mounting for an engine 10 which is required to impart via a chain and sprocket assembly a drive to a drum or other member displaced laterally with respect thereto, comprises a subframe or platform 14 on which the engine is actually mounted, a plurality of resilient buffer or shock absorbing devices 16 interposed between the sub-frame or platform and a base frame 15 or other rigid support and resilient buffer means 19 at least that side of the engine at which the drum or other member to be driven is or will be located, the resilient buffer means being located above the plane of the sub-frame or platform between a rigid upstanding member carried by the sub-frame or platform and a stationary abutment 17 carried by the base frame or other rigid support, the arrangement being such that the resilient buffer means will resist lateral tilting or displacement of the engine on its resilient mounting while allowing vibration thereof in the vertical sense. The resilient buffer or shock absorbing devices and the resilient buffer means may each comprise a block of rubber to each of two opposed faces of which a metal plate or the like is bonded. It may be feasible to employ coiled sponge or other appropriate shock absorbing devices. If desired an arrangement of posts or abutments and interposed buffer element may be disposed at the other corner of the sub-frame or platform 14 at the same side of the engine or alternatively at the diagonally opposite corner. The invention is particularly for engines such as may for example be employed for driving hoists or winches.

Alternatively a digital liquid crystal or 1. e. d. display may be used. If the watch is slow, exposure of photo-sensitive device 33 by-passes some of the divider stages; if the watch is fast, device 34 can be exposed to arrest the display. A further device 35 can reverse the direction of display drive, and a device 36 with gate circuitry 37 can zero the display to permit use as a stop-watch.

Abstract: 1,083,543. Measuring the power output cylinder of a piston engine, electrically. BROWN, BOVERI & CO. Ltd. Nov.11, 1964 [Nov.16, 1963], No.46018/64. Heading G1N. Relates to an apparatus for monitoring the pressure piston speed and power output in respect of each cylinder of an I. C. engine. Measuring piston speed Two 3 phase tachogenerators 3, 4, having output frequencies f and 2f respectively are driven by the engine crank-shaft. The generators are connected to transformers 13, 14 having a number of secondary windings each of which is selectively switched by a switch 17 whereby the phase of the voltage output is made to correspond to the crank angle associated with the particular cylinder under test. The output of transformer 14 is fed to a voltage divider 6 which is adjusted to set the relative magnitudes of the transformer output voltages to correspond to the ratio of piston rod length "L" to crank radius "r". The voltages are summed in an amplifier 5 the output of which represents the instantaneous piston speed in accordance with the expression piston speed and may be indicated on an oscillograph, (not shown). Measuring pressure A pressure transducer (e. g. inductive or Piezoelectric) is associated with each cylinder and each is connected to the cylinder selector switch 17. The output therefrom is amplified and fed to an indicator 9. A capacitor 8 charges up to the maximum output voltage and thus supplies to the indicator 9 a permanent standing voltage corresponding to the maximum cylinder pressure, i. e. ignition pressure. Measuring power The pressure representative output of amplifier 2 together with the piston speed representative output of amplifier 5 is fed to a multiplier 10, the output of which is fed via a smoothing filter 11 to a moving coil instrument 12 to provide a measurement of cylinder mean power output. Engine speed A moving coil meter 16 is connected to one of the tachogenerators to provide an indication of engine speed.

Abstract: 1,174,398. Laminated films. VISKASE Ltd. 13 Oct., 1967 [14 Oct., 1966], No. 46079/66. Heading B5N. [Also in Division B6] A printed film laminate is produced by printing on one surface of a synthetic plastics film using an ink which can become superficially dry yet retain solvent that can migrate throughit,- drying the printed surface until the ink is dry to the touch and then reeling the film up with a second synthetic plastics film so that the printed surface is an inner surface. Upon storage of reeled-up films, the solvent migrates from the ink and keys the two films together. Standard resin-based inks may be used with various solvents. The films may be of P.V.C. or polyvinylidene chloride or rubber hydrochloride and at least one of the films is transparent so that the printed matter can be seen. In one arrangement, the films 1, 2 are initially double wound on a roller 3, and cylinders 5, 6 print on the outer surface of the film 1 which is subsequently dried in an infra-red oven 7. The films are then tensioned at 8 and wound on to a roller 9 whereupon the printed surface of the film 1 adheres to the surface of the film 2 which had been outermost. In an alternative arrangement, only the film 1 is wound on the roller 3 and the film 2 is wound on to the roller 9 from a separate roller for lamination with the film 1.
