Title: Improved ultrasonic liquid depth indicator
IPC: G01S15/88
Filed: 1954-05-03
Abstract: 751,156. Ultrasonic liquid depth indicator. SPERRY PRODUCTS, Inc. May 3, 1954 [June 29, 1953], No. 12836/54. Class 118(2) An ultrasonic device for indicating the depth of liquid in a tank, which has no moving parts and is independent of the acoustic velocity in the liquid, comprises a strip 11 of acoustic conducting material mounted in the top of a tank 10 by means of electrically insulating material 40 and extending downwards to a point below the minimum level to be indicated. An electroacoustic transducer 12 is attached on one side 15 of the strip near the top and consists of a piezo-electric crystal 32 mounted on a wedge 33 such that only surface waves are generated in the strip 11. A series of holes P1, P2 ... &c., are formed in the strip 11 transversely to the direction of propagation of the waves and at regular intervals along the length of the strip. Pulses of ultrasonic energy are fed to the crystal 32 (for example, sixty times a second) and echoes from the holes P1, P2 ... &c., are received and fed to the vertical deflector plates or intensifier grid of a cathode ray oscilloscope (C.R.O.) whose horizontal sweep is synchronized with the pulse transmission. This produces a series of "graduation marks" on the screen. If the tank contains liquid the surface waves are substantially damped below the point at which the strip 11 enters the liquid and reflections from the holes below this point will disappear and the depth of the liquid may be ascertained from the number of reflections on the C.R.O. The holes P1, P2 ... &c., are arranged in a step-like manner, the near holes being further below the surface 15 and the more distant holes progressively nearer the surface, so that the echo signals will be of substantially constant magnitude. The holes are preferably sealed to exclude the liquid.

Title: Storage device for terminal
IPC: G06F13/00
Filed: 1973-03-20
Abstract: 1369184 Data transmission INTERNATIONAL BUSINESS MACHINES CORP 20 March 1973 [28 April 1972] 13368/73 Heading G4A A storage device 10 (Fig. 1) arranged to receive and transmit binary information between, e.g. a control unit 14 and terminal 20 includes an n stage shift register, a one bit in stage 1 of the register indicating that a unit of information is stored therein resulting in an examination of the contents of a predetermined stage to determine whether the information is a command or data word. As described the shift register has twelve stages, the words being of 13 bits, with the register being cleared on receipt of the 13th bit. Control unit 14 supplies control and data words to the storage device 10 which in turn supplies data and status words to the control unit, control words having a one bit in position 2. Bit 12 is a parity bit. A command word representing a poll request to a terminal has one bits in positions 2 and 4 which are decoded by the circuitry of Fig. 6B (not shown). If the parity is correct, parity latch is set to enable a gate (44) to respond to its other inputs to set a poll latch and poll output latch to generate an "output latch" signal. This results in a status word being provided by the selected terminal. A one bit in positions 3, 4 and 5 represents respectively that the device is busy, that the device is out of order, and the poll request parity was incorrect. The data is gated from the registers to the control unit by the circuitry of Fig. 8A (not shown). If the control unit then calls for a read operation indicated by a one bit in position 5 the word is decoded by the circuitry of Fig. 9A (not shown) so that a word is read from buffer store 21 into the shift register. If a write operation is called for by a command word having a one in bit position 6 the circuit of Fig. 10B (not shown) controls the entry of messages serially into the register, these being transferred in parallel into the buffer 21.

Title: Improved apparatus for the classification and concentration of ore bearing material
IPC: B03B5/60
Filed: 1923-05-23
Abstract: 220,714. Newsom, J. F. May 23, 1923. Stationary-vessel washing-apparatus upwardcurrent classifiers.-A box of rectangular section is provided with longitudinal and transverse rows of hoppers, each hopper being fitted with a spigot opening for settling out material. A horizontal fresh water current passes through the box under the horizontal ore-bearing current and carries off the fines, while the valuable materials pass through the current and settle out according to weight, the lightest material being carried farthest. The ore-carrying stream is fed at 1 into a pocket 2 having a vane 2a for breaking up the current. Thence the stream traverses a distributor 3 in the form of cells for ensuring a steady flow. To overcome eddies due to the feed current, a water current is led in from a pressure box 6 through a perforated plate 7 to the box 8, where it coalesces with the feed current. The solids settle out according to weight into hoppers 9 and pass through spigot openings 10, the heaviest materials settling at the head of the box 8 and the lightest at the overflow end. To prevent clogging of the cells, the distributor 3 is reversible by means of a hand-wheel 12 and is held by a spring-actuated dog 12a. For further washing, an apparatus as shown in Figs. 8-10 combines with the above arrangement an upward current in the spigot openings. Settling columns 22 are arranged in longitudinal troughs 19 and supplied with water through pipes 24 and mains 23. The water currents diminish in intensity away from the head of the box. The supply entering the columns 22 is distributed by a perforated screen 27 on an adjustable tube 26, the downward flow of material being through the spigot opening 25. With this arrangement a fine classification can be effected by varying the water supply at the settling columns.

In a device for pressing units of wire hooks 11, held in a comb 10, into the end of a conveyer or driving belt, the edges of the pressing jaws 7 are flush with the outer face of the casing 5 of the device, at least on one side, so that an operator behind the device may check visually that each time the belt is moved laterally (after pressing in one unit of hooks) the last hook of the pressed - in unit is correctly spaced from the first hook of the new unit in the comb 10. As shown, the end 10d of the comb 10 is flush with both the jaw edges and the casing, and when the last hook of a pressed-in unit is butted against the end 10d it is correctly spaced from the first hook of the new unit in the comb. A plain face 10c on the comb 10 facilitates a square positioning of the belt. Specifications 745,167 and 755,759 are referred to.

Abstract: 639,212. Retractive switches. ROCK, G. May 22, 1947, No. 13831. [Class 38.(v)[Also in Group XXXVIII] A switch adapted to operate the stopping signal of a bus or like vehicle comprises a strip of rubber or similar insulating material running the length of the vehicle and of the cross-section shown in Fig. 1. A strip-metal contact d is placed between the lugs b which are folded inwards as in Fig. 2. A second similar contact strip is placed on top of the folded lugs b and the side pieces c are folded inwards as shown at Fig. 3.
