Filed: 1973-11-05
Abstract: 1445452 Variable resistors ITW-ATECO GmbH 5 Nov 1973 [4 Nov 1972] 51250/73 Heading HIS A variable resistor comprises a plurality of resistance elements 8, Fig. 1, 60-62, Fig. 2, which within a region 26 are contacted by a pivoted slider, the resistance elements, and preferably also their contact portions, being produced by etching grooves 13 out of a chromenickel steel sheet which is mounted on a metal plate 11 electrically, but not thermally, insulated by a layer 10; the resistance elements are covered, except for region 26, by a further layer 8, both layers 8 and 10 being of a composite mica material, e.g. mica and polyamide fibres. The chrome-nickel steel, which may additionally contain molybdenum, is preferably laminated to layer 10 with adhesive. The resistive tracks may be connected in series or in parallel. To avoid sparking contact portions 65, 66 and/or slider contacts 3a, 3b are staggered, e.g. the contact portions may be disposed radially and offset circumferentially (Fig. 5 not shown) or they may be S-shaped and the slider contacts are staggered (Fig. 6 not shown). The metal plate 11 may be mounted in a supporting unit by means of through holes (24, Fig. 3 not shown). Arcuate slots (23) in the plate may be provided adjacent holes 24 to protect them from excessive heating. In addition the part of the plate beneath the region 26 may be punched-out to prevent short-circuiting to the plate. In another arrangement (Fig. 7 not shown) the edges of the plate are bent upwardly and two edges have inwardly bent sections (73, 74) beneath which the slider is mounted. The slider is actuated by a lever (14) pivoted on a holder (15) which is screwed to the plate. Various modifications of the slider and slider contacts are described with reference to Figs. 10-18 and 22-25, not shown. The resistors may be used as series resistors for the fan motors of car heaters. In Fig. 29 (not shown) the actuating lever can occupy three alternative positions defined by projections from the side of an aperture through which it passes. A further lever, e.g. for actuating an air valve, may be mounted adjacent the first lever. In the embodiment of Fig. 30 (not shown), resistive tracks which are relatively highly loaded are mounted vertically to improve the convective cooling thereof.

The shaft bearings and gears are supplied with lubricant through conduits such as 36 from a pump formed by a pick-up tube 35a extending into a rotating trough 35 which dips into lubricant contained in the bottom of housing 10. Tube 35a also communicates via restriction 37 with tank 38 so that excess lubricant is pumped into the latter from housing 10 so as to lower the lubricant level in the housing and thus reduce churning. Tank 38 is connected to the tank within centrebody 32 by a pipe 40 and the latter tank is connected to housing 10 by a pipe 41. The lubricant in the tanks is cooled by the passage of air through the turbine and a steady flow of cooled lubricant is returned to housing 10 through a hole 42 near the bottom of tank 38.

Abstract: A writing tube (3) is inserted into a cylindrical body (1). The equalising chamber is arranged on the surface of the cylindrical body and is covered by a sleeve (2) which can be slid from the front onto the cylindrical body (1). So that this sleeve can be easily pulled off the cylindrical body, its rear edge is equipped with so-called pressing surfaces (5) which ensure that when the sleeve (2) is gently twisted about the axis of the implement, the pressing surfaces permit displacement of the sleeve in an axial direction. These pressing surfaces (5) may have different shapes. <IMAGE>

Abstract: 1283554 Ultrasonic measurement of physical properties PANAMETRICS Inc 24 Oct 1969 [14 Feb 1969] 52318/69 Heading H4D A physical property (e.g. temperature or Young's modulus) of a sensor 11 whose resonant frequency varies from a nominal value as a function of the property is measured by applying to the sensor a unipolar acoustic interrogating pulse 19 having a duration of the order of T/2, where T is the period of the nominal resonance frequency, and measuring the frequency of the induced ringing 35 of the sensor. Sensor 11 is coupled to piezoelectric or magnetostrictive transmit/receive transducer 13 by a lead-in element 15 and the frequency is measured by digitally timing on counter 31 the duration of a selected number of cycles of the ringing. Delay circuit 21 and gate 23 ensure that transient oscillations at the start of the ringing are not timed. Counter 25 determines said selected number (e.g. 5). The timing may alternatively be done by analogue means. The acoustic pulse may be in the longitudinal and/or torsional mode (reply signals of the two modes being separately detected). Sensor 11 may be a solid cylinder (e.g. of ceramic, metal, plastics or composite material) or a fibre. Multiple sensors, as in Specification 1,202,182, may be used.
