Title: Improvements in washing machine
IPC: D06F37/12
Filed: 1969-04-29
Abstract: 1,262,773. Washing machines. GENERAL ELECTRIC CO. 29 April, 1969 [8 May, 1968], No. 21792/69. Heading D1A. A washing machine comprises, mounted in a chamber 6, an outer tub 2 within which is a substantially imperforate tub 47, both having their axes vertical during washing, means for causing washing motion of liquid and articles in both tubs and liquid inlet means 46 from which liquid is diverted to tub 47 until it is filled after which liquid enters tub 2 only. Perforated tub 2 has a heavy balance ring 8 and is rotatable for spin drying. Mounted within drum 2 is an oscillatory agitator 14 mounted on a shaft which rotates with tub 2 during spin-drying. A reversible motor 21 which rotating in one direction drives the agitator and in the other direction drives drum 2 for spin-drying also drives pump 27 which comprises two units 28, 29 operating respectively during spin-drying and washing. These units have inlets respectively in the lowest part of tub 6 and another part of tub 6 and outlets respectively to a drain and to a nozzle 35. Spinning may be delayed until unit 28 has lowered the liquid level sufficiently. The tub, motor &c are mounted on a bracket 36 carrying a counterweight 37 suspended by rigid members 38 each connected to a cable supported from the top of the machine. Tub 47 fits on to agitator 14 and has an outer wall with external vanes 53 and upwardly extending pipes 56 connected to bent tubes 57 with outlets 60 through which liquid passes during spinning. The discharge from horn 46, which is supplied with liquid at a predetermined temperature, is controlled by a cover forming a labyrinth passage through which liquid flows until tub 47 is full after which it overflows into tub 6. The discharge from nozzle 35 always passes over tub 47. A lint filter 72, 73 is provided. Reference has been directed by the Comptroller to Specification 939,526.

Filed: 1971-04-19
Abstract: 1331841 Acoustic reflectors; piezoel-ectric transducers MITSUBISHI DENKI KK 19 April 1971 [25 Feb 1970] 22270/71 Headings H4J and H4X A cylindrical electro-acoustic transducer element 1 (Fig. 5B) has an inner acoustic reflector 5 and an outer acoustic reflector 7. Both reflectors are preferably of substantially conical shape but the outer reflector 7 may be circumferentially incomplete (Figs. 5A, 5C). Phase matching of acoustic energy from the inner and outer reflectors is achieved by appropriate selection of the angles of the cones and the operating frequency so that waves transmitted in the direction P reinforce each other. The transducer element 1 is of barium titanate or lead zirconate lead titanate. The reflectors 5, 7 may be produced by using curved generator lines instead of straight generator lines as shown. An acoustic shield 8 provides selected directivity. The devices are for transmission or reception of audible or ultrasonic signals.

Patent GB-223301-A (GB)
Abstract: 223,301. Haddan, R., (National Cash Register Co.). July 17, 1923. Machines with several item-value totalizers, the engagement of which with the differential actuating mechanism is controlled mechanically by means superposed upon and over-riding the keyboard control, as in Specifications 191,350 and 203,995. The mechanical means in this invention comprise a number of notched plates 82 set differentially by the special keybanks and controlling a number of multi-pronged pawls 86 interposed in the totalizer-engaging mechanism. When the plates occupy positions such that the presence of a notch or notches permits the pawl under the influence of a spring to move towards the plates, the corresponding totalizer line cannot be engaged. The pawls may be replaced by others having their prongs differently arranged in order to vary the control. In the form shown, the pawls 86, three in number corresponding with the three lines of totalizers, have two prongs engaging the first and third notched plates or discs 82 and an oppositely-extending prong to engage the second plate. These plates are differentially positioned under the control respectively of a clerk's bank, the transaction bank and a second clerk's bank, and the three pawls control the engagement of the three lines of totalizers assigned respectively to the three banks of control keys. The totalizer lines are moved in to engage with the actuators by means of links 110, Fig. 5, provided with pins 109 adapted to be embraced by the hooked arms 108 of a spider plate 107. This plate is rocked clockwise by cams 88, 90 on the main shaft 30, and if a pin 109 occupies the position shown in Fig. 5 the link 110 will be drawn along and the selected totalizer engaged. The pins 109 are, however, also controlled by a slotted arm 119, Fig. 6, embracing a pin 118 on the link 110 and pivoted to a plate 121 rocked clockwise and then counterclockwise from a cam 123 through link 128 and three-armed lever 130. The pawl 86 is mounted at 131 upon this arm 119, and the arrangement is such that, provided obstacles to the movement of the pawl 86 towards the centre 84 are offered by the peripheries of the plates 82, the counterclockwise rocking of plate 121 causes arm 119 to swing about pivot 131 and thus move pin 109 into the embrace of arm 108, so that the corresponding totalizer line will be shifted into engagement. If, however, the first and third plates 82 both present notches to the two prongs of a pawl 86, or the second plate presents a notch to the single prong, then the pawl is free to move inwardly and the arm 119 merely rocks about pin 118, so that pin 109 is not shifted into effective position and the totalizer line remains disengaged. Specification 8119/15 also is referred to.

Title: Improvements in or relating to track car counting and indicating arrangements

Filed: 1959-07-01
Abstract: 901,496. Electric selective signalling systems. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. June 14, 1960 [July 1, 1959], No. 22577/59. Class 40 (1). [Also in Group XIX] A track car counter comprises a first uniselector with one bank of contacts having impedances of a lower value connected between successive contacts thereof and a second uniselector operated sequentially to the first and having two banks of contacts with impedances of a higher value connected between successive contacts of both banks, the impedances of lower and higher value being so interconnected that on connection of terminals of the second uniselector between a voltage source and earth, an output terminal of the first uniselector has a voltage of an amplitude dependent on the amount of rotation imparted to the two uniselectors. As described, for counting the number of cars entering a siding of prescribed capacity, a counter comprises two twelvecontact uniselectors having banks U1, U2, U3 and T1, T2, T3, respectively. Resistors U1R of 100 ohms are connected between the contacts of the bank U1 and resistors T1R of 1200 ohms between the contacts of the bank T1. Between the contacts of the bank T2 are connected a number of 1200 ohm resistors T2R, the connections depending on the siding capacity. The siding capacity determines the values of resistors R1, R2 and the arrangement of connections a, b and c. A positive potential is connected to the wiper of bank T1 and earth is connected to the wiper of bank T2, the wiper of bank U 1 being connected to a line marked TAP, the potential of which decreases step-by-step for each car which passes into the siding, earth potential being reached when the siding is full. Pulses from a track car detector, one pulse for each car, are applied to a terminal P to operate the magnet U12/3 of the " U " uniselector once for each pulse, the magnet T12/3 of the " T " uniselector being operated once each 12 steps of the " U " uniselector over a contact 11 of the bank U2. A " nearly full " alarm can be preset to operate at any desired number of cars before the siding is full. For this purpose, strappings TAL, UAL are made to appropriate contacts in the third relay banks T3, U3, a relay AL/2 being energized to actuate the alarm, which continues until the counter is reset. Resetting is effected by energizing for at least half a second a relay RS/7, thereby opening the input circuit and closing self-drive circuits for both the " T " and " U " uniselectors which are thus returned to their " N " or initial positions. In second and third embodiments (Figs. 2 and 3, not shown), the connection of the resistors between the contacts of the selector switches is modified, the uniselectors being set initially to predetermined positions and stepping on to reach a zero state when the siding is full.
