Abstract: 643,384. Floor scrubbing machines. DANI ELSSON, N. J., and SUNDIN, H. Dec. 20, 1947, No. 33706. Convention date, Nov. 2, 1944. [Class 138(i)] A floor scrubbing machine, Fig. 1, of the tvpe comprising a circular brush 5 driven about a vertical axis by motor 6 and gearing 7, a liquid container 2 with means for supplying the liquid to the floor, e.g. a manually operated valve 44 and conduit 8, and a nozzle 10 with suction means, e.g. conoduit 11 and pump 4, for returning the dirty liquid to the container 2, is characterized by the nozzle 10 completely surrounding the brush 5. It is preferably made of rubber and has a lower lip which contacts the floor. The dirty liquid delivered from the pipe 3 drains through a filter 1 into the container 2.. The brush assembly is preferably mounted on springs 9. The Specification as open to inspection under Sect. 91 describes modifications, Figs. 3 and 7 (both Cancelled). As shown in Fig. 3 (Cancelled) the casing 15 is supported on wheels 14 and comprises a liquid container 2 having a draincock 12 and a valve 44 operated by knob 13 which admits liquid to the floor at the centre of the brush 5. The brush 5 is rotatably mounted in plate 26 and is driven through gears 28, 7 from the motor 6, the motor also driving a pump 4. Surrounding the brush 5 is a rubber mouthpiece 10, connected by pipes 11 to the suction side of the pump 4 whereby excels water is collected and delivered by pipe 3 into the top of container 2, whence it passes through a filter 1 back into the lower part of the container. The container may be electrically heated. The pump 4 may be primed at the beginning by opening valve 45 with knob 27. The plate 26 carrying the brush and rubber mouthpiece 10 is pressed into contact with the floor by springs 9. A ring of absorbent material 23 may be provided, let into an annular groove 24, and the latter may be connected by pipe 25 with the suction side of the pump. A vacuum cleaner nozzle, also connected to the suction side of the pump, may be provided near the periphery of the mouthpiece 10. In a modification, Fig. 7 (Cancelled), a cylindrical brush 38 may be employed, rotating on a horizontal axis. In this case the brush is surrounded by a casing 40, and the mouthpiece 10 is straight and located on one side of the brush. This subjectmatter does not appear in the Specification as accepted.

Title: High speed computer

Filed: 1964-08-21
Abstract: 1,082,978. Digital computers. TOKYO SHIBAURA ELECTRIC CO. Ltd. Aug. 21, 1964 [Aug. 22, 1963], No. 34389/64. Heading G4A. A digital computer arranged for parallel computations includes a periodic function generator 50, Fig. 15, for a function g(x) and having an incremental output 1, 0, -1 at predetermined values controlling a gated input 56 for a second function F(x), whereby the product of the functions is cumulatively added. Counters 57 and 59 add previously stored values from a memory 73 which is addressed by a successive address difference calculator 75. The arrangement is applied to spectroscopic analysis of far infra-red rays using an interferometer in which the intensity is determined over an incrementally stepped range of mirror positions and a series of separate calculations made for individual wavelengths at each position. The intensity is analysed by Fourier's equation to determine the energy distribution for different wave numbers (inverse of wavelength). Inputs to the computer comprise increments #V of wave number and #X of mirror movements, the output for given wave numbers being cumulatively added to give the total energies. An addressing system is described whereby values of the periodic function (cos 2#VX) over a single period are so addressed by encoder 72 as to be in correct sequence for use over a whole series of periods. As shown in Fig. 11 points 1-5 required sequentially in a series of periods (c) can be re-addressed over a single period (d) in a sequence determined by adding the address difference to a cumulative adder 7 of predetermined capacity, the overflow being encoded at encoder 72.

Filed: 1973-07-19
Abstract: 1440807 Retractive reversing switch; trigger switch SKIL (NEDERLAND) NV 19 July 1973 [27 July 1972] 34506/73 Heading H1N A reversing switch for incorporation into the housing of a portable tool driven by an electric motor has a pivotal reversing arm 14 mounted on an operating trigger 12 for acting on a shuttle 37 which is slidable within an opening in an elongate extension of the trigger and which has a depending portion 45 for engagement with one or other of pockets 43, 44 in corresponding contact carriers 31, 32 in order to preselec the electrical connections to be switched into circuit when the trigger is depressed to energize the motor. Each contact carrier 31, 32 supports a movable contact such as 52 which is spring loaded by a spring 53 for abutting and sliding engagement with an arrangement of fixed contacts 60-66 mounted on an insulating base as a subassembly 22. In the OFF position an upstanding contact ear 52a is held engaged by means of the carrier restoring spring 47 with a formation 61a of a fixed contact 61 which terminates in a terminal 61c within the base. On movement of a selected carrier, say 31, by depression of the trigger 12 the contact 52 first pivots under the action of spring 53 for its contact faces 52b and 52c to bridge fixed contacts 62, 65 with a snap action and then continues to slide until ultimately the bridging is between fixed contacts 62, 66. A slot 71 in the subassembly 22 accommodates a circuit board 70 for speed control including resistances 73, 74 and a slider 74 (Fig. 6, not shown) which function in conjunction with the trigger movement and in the full speed position when the contact 66 is engaged the speed control circuit is by-passed completely. The subassembly 22 mounts the terminal ends for the various fixed contacts to which external connections to the motor are made and these are explained with reference to circuit diagrams Figs. 6-8 (not shown).

Abstract: 1,148,527. Determining hardness of rock. COAL INDUSTRY (PATENTS) Ltd. Aug.12, 1966 [Aug.13, 1965], No.34743/65. Heading G1S. Apparatus for use in determining the hardness of a sample of rock S comprises a flexible beam 12 anchored at each end, a hardened metal conical tip 21, means 1 to 5 for moving the tip in the direction of its major axis to introduce the tip into a sample of rock interpored between a flat face of the beam and the tip, the beam having a stiffness such that as the tip penetrates the sample, the beam 12 deflects under the load imposed upon the sample by the tip, means 22 for indicating the degree of deflection of the beam, and means 14, 16 for indicating the distance the tip is moved in the said axial direction. To determine the hardness of a sample of rocks, the sample is introduced between the flat metal strip 12 and the point of the conical tip 21 which is moved by rotation of the micrometer gauge thimble 16 and shank 17 into contact with the surface of the sample. The micrometer reading then being taken before the thimble 16 is further rotated so that the pointed end of the conical tip will penetrate the sample and additionally the load imposed upon the tip will cause the metal strip 12 to deflect, the degree of deflection being registered through plunger 25 on the deflection gauge 24. The distance the tip has penetrated is determined by subtracting the deflection gauge reading from the difference between the micrometer readings.

Abstract: 1381990 Metallized azo dyes CIBA-GEIGY AG 27 July 1972 [27 July 1971] 35243/72 Heading C4P New heavy metal complexes of azo dyes of formula D-N-N-K wherein D represents the radical of a heterocyclic diazo component containing an ionizable metal complex-forming group or a metal complex-forming position (as hereinafter defined), separated from the azo bridge by one or two atoms, and K represents the radical of 2-amino-3-hydroxypyridine or a 5-halogeno-2-amino-3-hydroxypyridine are described. By "heavy metal" is meant a metal having an atomic number in the range 23 to 30 inclusive. The term "metal complex-forming position" as used herein means a position at which free electron pairs are available to form a co-ordinate bond with the metal atom. Suitable such complex-forming positions are, for example heteroatoms, especially nitrogen atoms, in a heterocyclic ring of the radical D or the oxygen atom of a keto group. The dyes are prepared by azo coupling followed by metallization, e.g. with Cr, Co, Cu or Ni compounds. The dyes may also contain fibre-reactive radicals and are used to colour silk, wool, leather, polyurethanes, polyacrylonitrile and, in particular, synthetic polyamide fibres in blue shades.
