Abstract: 1527308 Measuring concentration of a solution DIAMOND SHAMROCK CORP 19 Nov 1976 [20 Nov 1975] 48391/76 Heading G1N An apparatus and process for measuring the percent concentration of an electrolyte in solution is disclosed. The apparatus includes a crystal oscillator 30 generating a squarewave and a wave shaper 38, 40 to transform the wave into a monochromatic sine wave which passes through a twostage temperature compensated first buffer amplifier 45. Alternatively a sine wave may be generated directly. The sine wave passes between electrodes which project into the solution under investigation and generates an output. A second buffer amplifier 86 operates on the A.C. component of the output from the solution and is operatively connected to a half wave rectifier 104, 105. The output of the half wave rectifier is proportional to the percent concentration. A termperature control device 80 is utilized to hold the solution at a constant temperature. An alternative embodiment utilizes two identical circuits with two different solutions. One circuit is used with a solution having a known concentration and one with an unknown concentration. The outputs are compared in a differential amplifier Fig. 4 (not shown).

Title: Dictation system
IPC: H04M11/10
Filed: 1964-11-30
Abstract: 1,030,099. Transistor switching circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 30, 1964 [Dec. 30, 1963], No. 48519/64. Heading H3T. [Also in Division G5] A dictating machine includes a switch which is moved by the recording head as it advances, but is not responsive to back spacing of the head, the switch being arranged to prevent recording of signal indicative of the end of a recording, when the head has been back-spaced, until the head has re-advanced to the end of the recording. The machine is employed in a dictation system having a central recording machine and one or more remote dictating stations. In one form of control circuit, Fig. 3, a negative potential derived from contact 100 is applied to a record switch 43 and a review switch 44 which control the forward drive and back spacing of the machine. In order to record, the hand set is raised at a remote station energizing relays 28, 29, and the record switch 43 is operated energizing record relay 52, clutch 59 and forward run relay 71. The material dictated may be played back by operating switch 44 which energizes the " kickback " relay 124, clutch 59 and forward run relay 71. Replacement of the hand-set releases relay 28, relay 29 remaining energized over a self-hold circuit including contacts 36, 37 with relay 28 released, the negative potential on contact 100 is applied to the oscillator 84 and clutch 59 to record a control signal. As the transducer moves contacts 39, 41 open and relay 29 releases, terminating the recording. If at the replacement of the hand-set the transducer was at the end of the recorded material contacts 64, 65 are closed and the recording of the tone commences as soon as the hand-set is replaced. If this is not the case, the transducer moves until it closes contacts 64, 65 at the end of the recorded material before recording commences. Play-back by a subsequent user of material recorded prior to the signal is prevented by an inhibit circuit which effectively isolates switch 44 from the kick-back relay 124. Inhibit circuit.-If switch 44 is actuated in the absence of a recorded control signal, a pulse is fed via capacitor 108 which momentarily switches on transistor 105 and energizes relay 107. Contacts 100, 101 then close to pulse the kick-back relay. If switch 44 is actuated in the presence of a recorded control signal, this is fed to the inhibit circuit via capacitor 116 and is rectified to provide a bias which hold transistor 105 conducting and maintain relay 101 energized. Switch 44 is thus disconnected from contact 100, and cannot produce further pulses for kick-back relay 124. Similarly, switch 43 is rendered inoperative. In an alternate arrangement, Fig. 4 (not shown), the transistor is held biased off by the control signal, and the negative potential is permanently connected to line 33.

Onions are peeled by first slitting the skin and then removing it by means of a blast of fluid. A suitable machine includes a conveyer 6 having apertures of a frustroconical form capable of maintaining an onion 14 in a stable position, the onions being fed on to the conveyer from a hopper (2) and orientating device (4), which conveyer transports said onions to a position in which the skin can be split by engagement of the onion 14 with an electric resistance heating wire 17 extending vertically across the concave face 16 of a block 15. The block 15 is moved in order to contact the wire 17 with the onion 14 by means of a solenoid 34, the onion being held in position by means of a solenoid operated holder 39 comprising a shaft 40 to which is attached the holding body 43 having a radially outwardly extending flanged 43<SP>1</SP>, to the lower circular face of which is attached a rubber or flexible plastic annular plate 44 having a bevelled radially inner wall 45 which contacts the crown of the onion. The conveyer 6, which is driven in a stepwise manner, is coordinated with the solenoid 34 such that the slitting blocks 15 are only activated when an onion is stationary in a position adjacent to the block 15, or in an alternative embodiment, between two of said blocks 15. The wire 17 may be replaced by an abrasive blade or wheel, a saw-edge blade or wheel, or a burner providing a flame having a fine circular section tip or an elongate cross-section. After the splitting block 15 has been separated from the onion 14, the latter is carried on the conveyer to a peeling chamber 46 (Fig. 4) which consists of upper and lower chamber parts 47 and 48, mounted on vertically movable shafts 52 and 53 respectively, enclosing a space 49, sealed with respect to its surroundings, into which peeling fluid is introduced by the inlet conduit 50 and from which peeling fluid is removed by the outlet conduit 51. Air or alternative peeling fluid is passed into the chamber at a pressure of preferably about 20 p.s.i.g. but at least 5 p.s.i.g. and removes the skin of the onion 14, the skinned onion then being passed to a screening belt (20) for separation of the skins from the opions by means of an air blast.
