Title: Improvements in or relating to instrument dials for depth sounding indicators
IPC: G01S1/72
Filed: 1945-03-06
Abstract: 627,827. Instrument dials. STEVENS, A. H. (Submarine Signal Co.). March 6, 1945, No. 5616. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 23, 1946.] [Class 106 (iv)] [Also in Group XXXVIII] A multi-range indicator particularly for echo depth-sounding apparatus comprises two transparent dials, the outer bearing scale calibrations and means for masking all but one of a plurality of sets of indicia carried by the inner dial, means for the indirect illumination of the dials and, if desired, means for changing the range of the instrument and the range of the scale simultaneously. As applied to echo depth-sounding apparatus, a transparent dial 1, having on its rear face scale calibrations 3 and an opaque annulus 4 with apertures 5, is mounted on a hub 24, which also carries a second transparent dial 2, having on its front face two sets of indicia 6, 7. The opaque annulus, the calibrations and the indicia are preferably printed by the screen process, the last with a translucent pigment. A plurality of light sources 10 is mounted in an annular channel 9 in a frame 8, in which the dial assembly is mounted by means of a bezel 28, which also serves to conceal direct light from the observer. Light is reflected and dispersed by the white-painted - interior surface of the channel 9 and a series of angle-shaped reflectors 11, which also prevent direct light from penetrating the edges of the dials. The range of the scale can be changed by turning a knob 20 fixed to a shaft 19 working in a bushing 18 in the front dial 1 and controlling an eccentric cylindrical cam 21, which co-operates with a slot in the dial 2, rotation being limited by a pin 23 in the cam 21 cooperating with stops formed by the shaping of the bushing 18. A disc 14, rotated at constant speed by a motor 15, carries a neon tube indicator 16 behind a slot 17. The motor's torque is transmitted to the disc 14 through a shaft 29, a pinion gear 30 fixed thereto, a pair of gearwheels 31, 34 freely mounted on shafts 32, 35 carried by a cover plate 33 freely mounted on the shaft 29 and a ring gear 36 fixed to the disc 14. The range of the instrument depends on the speed of rotation of the indicator which can be changed by freeing or fixing the cover plate 33 for or against rotation by means of a brake shoe 38 mounted on an eccentric shaft 39 on the cam 21 and so controlled by the knob 20 simultaneously with the scale-changing means. While the cover plate is free to rotate, relative rotation between the gears is prevented by a leaf-spring 40, fixed to the cover plate, bearing frictionally on a shoulder 41 of the gear 34. In a modification the second dial is provided with a single set of indicia and the front dial with a series of opaque areas, which, upon the relative rotation of the dials, masks the final digits of the indicia, thus in effect providing a second set of indicia. In a further modification, light polarizing means are employed to mask the final digits.

Title: Improvements in or relating to variable electric condensers
IPC: H01G5/16
Filed: 1925-12-11
Abstract: 266,760. Goldberg & S÷hne, Ges., M. J. Dec. 11, 1924, [Convention date]. Condensers have the variation in capacity effected by the action of heat, the arrangement being particularly adapted to fire alarms, especially those which operate wirelessly. In one form, Fig. 1, the fixed plate 270 is mounted on an insulating frame and the movable one 272 is carried on a bimetallic strip 274. In another form, Fig. 2, the condenser is formed by mercury or an electrolyte in a glass type 279, and bv mercury or an electrolyte in another tube 280. insulating material 283 fills the lower part of the tube 280 which carries a coating 281 serving as a protection against heat radiation and extraneous electrical influences. The leads are connected to the mercury in tube 280 and to a coating 282 around the receptacle 278. In the modification shown in Fig. 3, a glass globe 286 contains a quantity of electrolyte 287 below which dips a tube 289 carrying a coating 290. The capacity is varied by expansion of the air or gas in the globe above the electrolyte driving the latter up the tube, the sensitiveness being increased by more or less tilting the apparatus. The Specification as open to inspection under Sect. 91 (3) (a) states also that instead of the condenser being responsive to the temperature of the surrounding air, the heat-sensitive elements may be influenced by a heating coil surrounding the members 274, 278, and 286, the current through the coil being measured by the capacity. Further, the invention is applicable to electrically measuring continuously varying temperature. This subject-matter does not appear in the Specification as accepted.

Abstract: 1464445 Facsimile systems MITSUBISHI DENKI KK DAINIPPON INK & CHEMICALS Inc and M MURATA 8 Feb 1974 [19 Feb 1973 20 Feb 1973 21 Feb 1973] 05977/74 Heading H4F Colour-separations for printing an original 2 are recorded on a photosensitive film 4, each colour component signal from the photoelectric analysing head 100 being fed to the recording head 101 via an amplifier 9, shaping circuit 10, gate circuit 16 and a bleed allowance/overlap allowance adjusting circuit 102 which includes a memory circuit 17 for the circumferential direction of scanning around cylinder 1, an expanding/contracting circuit 19, a memory circuit 18 for the transverse (axial) scanning direction and a second expanding/contracting circuit 20. The memories 17 and 18 and the gate circuit 16 are controlled by output pulses from a pulse shaping amplifier 15 supplied by a rotary encoder 14. Bleed allowance which compensates for the estimated dye blurring is effected by contracting the width of each colour component pulse at its leading and trailing edges by a set amount (e.g. one or two times the period for which the analysing or recording light spot scans an elemental area i.e. diameter of the light spot). Overlap allowance which ensures that the boundary between different colour patterns printed on a cloth are not left undyed is effected by expanding the width of each colour component pulse by a set amount. The bleed or overlap allowance is generally 0À1 to 0À5 mm. depending on the kind of cloth. The memory circuits 17 and 18 each comprise a plurality of clocked shift registers (Figs. 3 and 5, not shown), with a plurality of output terminals selectively connectable to an AND gate for bleed allowance or to an OR gate for overlap allowance (Fig. 4, not shown). To enable accurate repeat printing the apparatus may include an enlarging/compressing circuit in addition to the expanding/contracting circuit (Fig. 7, not shown), which includes a multistage register operable at different write and read frequencies for enlarging/compressing the overall circumferential size of the recording with respect to the circumferential size of the original. Enlargement/compression in the longitudinal direction may be effected by adjusting the relative feed speeds of the detecting and reproducing systems. Magnetic drums, tapes or discs may be used instead of shift registers in the memories.

Abstract: 1,025,094. Endless conveyers. ELECTROLUX A.B. Feb. 15, 1963 [Feb. 16, 1962], No. 6180/63. Heading B8A. A storage and/or sorting system for boxes L, M, N comprises a continuously driven endless conveyer 20 along which the boxes are fed to their relevant storage paths 24, a control device 28 comprising an endless belt or drum synchronously driven with the conveyer 20 and having pins 50 which actuate microswitches 51, 55 to control a box stop device 29 in the conveyer path and switch devices 25 for depositing the boxes into their respective storage paths 24 once the box has operated a valve 65 at the head of each path 24. A box N is fed automatically to the correct path 24 once an operating member 27 on an operating board 26 is depressed to connect the micro-switch 51 with a current feed line 57. The relevant pin 50 closes the micro-switch 51 which through a system of valves 58, 59 causes a pneumatic cylinder 60 to operate to lower the stop device 29 and to raise it after the box N has passed by. The said pin 50 on the control device 28 now moves in synchronism with the box N and operates the micro-switch 55 at the same instant that the box arrives on its relevant switch device 25 and operates the valve 65. Through a system of valves 61, 62 a pneumatic cylinder 63 is operated which causes the switch device 25 formed from rollers, to pivot about the storage path 24 whereupon the box gravitationally passes along the rollerway path 24 to a stop 37 at the discharge end. During this movement the box N operates a valve 70 which causes the switch device 25 to be lowered. At the discharge end of the storage path 24, the box actuates a valve which causes a rollerwaytype switch device 31 to be pivotally elevated pneumatically, as with the switch device 25 once the circuit for that storage path has been manually selected. The box then rolls on to an endless discharge conveyer 32 where it operates a further valve to cause lowering of the switch device 31. A stop device 38 is preferably provided in the discharge conveyer line of travel. A stop device 38 is preferably provided in the discharge conveyer line of travel. The control device is driven through a reduction gear 30 from one of the end drum shafts 43 of the conveyer 20. The sets of micro-switches 51, 55 corresponding in number to the number of lines of pins 50 and to the number of storage paths 24 which may be mounted on common holders 52, 56. The storage paths may extend from both sides of the conveyer 20 and may be arranged in more than one horizontal plane. Photo-electric devices may be provided to give warning of a full storage path.
