Filed: 1942-11-04
Abstract: 553,494. Making circular saws. RICKENMANN, A. Nov. 4, 1942, No. 15526. [Class 60] Circular saws are cut from blanks by a cutter having helical teeth the pitch of which is twice that of the teeth to be cut, the number of teeth being odd. The blanks are mounted in a batch on an arbor 5 which can be traversed axially and the cutter 13 on a shaft 12 in a plane at right-angles thereto. The cutter makes one revolution while the blanks advance a distance equal to twice the pitch of the teeth the number of which is odd so that on the second rotation of the blanks teeth are cut between those already cut.

Abstract: 1508177 Analogue-to-digital conversion NIPPON ELECTRIC CO Ltd 16 April 1975 [16 April 1974] 15637/75 Heading H3H In non-linear analogue-to-digital conversion by the successive approximation method, the comparison signal is generated by injecting currents into a resistive ladder network (not shown) at points selected by logic, Fig. 4, controlling switches SW1-SW8, the most significant bit being derived by turning on SW1 and SW2 and the next bit by turning on SW3 or turning off SW2 according as the comparison signal exceeded or did not exceed the input analogue signal to be coded, the remaining (four) bits being determined using a group of four consecutive switches selected according to the values of the first two bits. Thus, if the first two bits were 11, switch SW 1 is turned off and switches SW2-SW5 are used; if 10, switch SW1 is left on and switches SW3-SW6 used; if 01, SW1 and SW2 are left on and SW4-SW7 used; if 00, SW1-SW3 are left on and SW5-SW8 used. The logic receives the comparison output on line 61, reset pulses on line 62 and clock pulses at the bit rate on line 63, and comprises bistable memories M1-M8 and a shift register SR1-SR6. A polarity bit and one other amplitude bit may be derived by a preliminary folding stage and variable gain amplifier (not shown).

Title: Thermal imaging devic3
IPC: G01J5/42
Filed: 1973-04-04
Abstract: 1415078 Modulating light PLESSEY CO Ltd 27 March 1974 [4 April 1973] 16014/73 Heading H4F In a thermal imaging device a major surface of a body of a low thermal conductivity material, e.g. glass, has a linear or two-dimensional array of depressions therein and a flexible membrane with a reflective coating is secured thereto to cover and enclose each depression to form an array of individual cells each filled with gas. In use the device is disposed to reflect visible light between a pair of multi-channel coolinators each transmitting a pattern of beams corresponding to the pattern of cells, and thence to a display screen. When a thermal image is incident on the device, e.g. on the sides of the cells opposite the membrane, the gas is heated and expands to distort the membrane, whereby the light intensity at the associated position on the display screen is reduced. As particularly described, the membrane is of rubber with an evaporated metal reflective coating. If each cell has a capillary gas leakage path, an image is produced only when the thermal pattern is disturbed, e.g. providing a malfunction warning in monitoring processes. To provide a constant image, the thermal image in this case is chopped, e.g. by rotation of a plane mirror in a Cassegrain system.

[Class 6 (i)] A wheeled implement for working the land and carrying tools behind the wheel axle is provided with handle-bars A<1> which are inclined downwardly and are provided with depending portions A<3> which carry the wheel axle. Obstacles encountered by the tool tend to lift the tool and rotate the handle-bars about the wheel axle. The tool may consist of a blade D carried by the lower members A<2> of the frame and additional tools 12 may be supported on a stud 13 and a bracket 15. Fig. 13 shows a modification in which the tools are supported by arms A<5> depending from the frame or handle-bars A<1>. The arms A<5> carry a plate 20 which has depending lugs 21 and a member 20a carrying a stud 23 which supports the tool arm 22. The latter is held in contact with the under surface of the plate 20 by a spring 24. Fig. 16 shows a device whereby the tools can be secured in various positions along the plate 20. A removable rod 26 passes through holes in lugs 25 depending from the plate 20 and the tools are suspended from the rod 26 between any pair of the lugs. The tools are provided with springs 24 which are secured to hooks 28 on the plate 20. The axle C of the wheels is secured in position as shown in Fig. 17 by a pin 29 passing through a hole in the axle and through a hole in a lug 30 projecting from the frame A1.

Abstract: 900,891. Determining relative quantities of fluid mixture constituents. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. May 5, 1961 [May 6, 1960], No. 16114/60. Class 37. In a flame detector for measuring the conductivity of a flame to determine the concentration of organic material in a gas which may be a hydrogen carrier from a chromatography tube, a third electrode 9 is positioned between a pair of electrodes 6, 2 which are connected in series with a power source 7, whereby a varying voltage from a source 10 applied to the third electrode can temporarily and repeatedly interrupt the current from source 7 so that a variable signal which may be amplified in an A.C. amplifier 11 is developed across a load resistor 8. In a modification described with reference to Fig. 2 (not shown) in which a plurality of load resistors 8 provide for the selection of different ranges, the current across the detector flame is opposed by the current through a reference flame detector burning pure hydrogen, and a further electrode is provided as an electrostatic screen to prevent induction in the measuring circuit from the varying potential source 10. A detector cell having concentric mesh electrodes around the burner is described with reference to Figs. 3 and 4 (not shown). Inaccuracy in the detector due to the current peaks after interruption by a positive voltage peak from source 10 being different from those following a negative peak, which are presumed to be inaccurate due to space charges is overcome in a further embodiment by removing the latter. A switch which is synchronized with the variations in source 10 which may be a vibrator or a transistor switching network is used to eliminate the unwanted half cycles and may only sample the electrode current in the vicinity of its peak, a filter then being provided to eliminate the source frequency and smooth the pulses.

The support is raised, when the lid 16 is opened, by links 54 pivoted to the carriages and the lid, and is locked in raised position by a pawl 64 engaging a recess 66 in the guide rail. The pawl is released, when the lid is lowered, by a bevel 70 on the link 54. Descent of the support is braked by a vane 92 moving in a liquid chamber 90 and provided with a restricted orifice and a one-way valve. The lid is locked in closed position by a spring 74, and is raised slightly, when the spring 74 is released by a push rod 82, by means of a spring 84. The chamber 22 is supported in a recess 20 in a sink or worktable 10. It is provided with a swinging washing spray 26 and a fixed rinsing spray 28 supplied by separate pumps 30 driven by a common electromotor. Washing and rinsing liquids are contained in tanks 32.

The housing cover of a centrifuge is locked, released and/or opened by means of electrical apparatus comprising a permanent magnet 3 which is rotatable with the centrifuge drum 2 and may be situated on the edge thereof, an induction coil 6 which pass the pulses generated by the movement of magnet 3 to an amplifier 7 and on to a thyratron 8 which is adapted to be quenched upon receiving a pulse from the induction coil and to remain quenched as long as pulses follow one another in a sufficiently dense series to prevent a relay 9 which controls the locking, releasing and/or opening of the housing cover from becoming actuated until the centrifuge slows down, e.g. on braking. Thus relay 9 operates the switch 10 which when drum 2 is rotating switches on the circuit 11 for the locking magnet of the cover and a pilot lamp circuit 12, and when the drum is at rest, breaks the circuits 11 and 12 and closes circuit 13 which allows compressed air to enter a pressure cylinder for opening the cover. The Specification refers to German Specification 922,580 which discloses a device wherein the cover of the centrifuge is released by a magnet which is controlled by a time responsive relay. The relay may be delayed in its action by current pulses from a pulse generator. The pulse generator may take two forms. It may be a contact roller or disc mounted on the shaft of the centrifuge drum and in contact with brushes which are connected to the relay. Alternatively, the pulse generator may be a transformer in which the magnetic flux is interrupted by an armature arranged on the end of the shaft of the centrifuge.
