Title: An electro-mechanical device for pre-selecting and controlling the speed of one or more electric motors driving movable machine parts
IPC: B60K23/00
Filed: 1947-09-29
Abstract: 644,070. Controllers; control of motors. BERTHIEZ, C. W. Sept. 29, 1947, No. 26281. Convention date, Oct. 25, 1946. [Class 38(iii)] An electromechanical device for controlling the speed of one or more electric motors comprises a single lever movable in a grid about two axes at right angles to each other to control a preselector and a double system of contacts which contact and make effective the selection or alternatively stop the motor, the lever being automatically biassed in the path of the preselecting movement. A lever 1 is pivotally secured to a shaft 2 so that horizontal movement of the lever in the grid 9 rotates the shaft 2. to actuate a switch 7 while vertical movement of the lever operates contacts 16 or 17 by means of a cam 15 slidable along the shaft 2, the lever being returned to the horizontal position by meeans of a spring 4. Rotation of the switch 7 selects the desired speed or movement, upward movement of the lever then operating contacts 17 to start the movement while downward movement operates contacts 16 to stop the motor. Any known method of interlocking may be used to cancel one movement when the lever is moved to select a further movement and means may be incorporated to ensure that the lever is always positioned opposite a vertical slot in the grid. If the movement is to be reversible a contact must be incorporated in the switch 7 so that when moving the lever to select the reverse movement the contact is operated to stop the motor before the reverse movement is started by vertical movement of the lever. Alternatively, a portion of the horizontal slot 10 may be lowered to assume the position of the slot 18 thus ensuring that the lever is moved to the motor stopping position when a reverse movement is selected thus the additional contact in the switch 7 may be dispensed with. The Specification as open to inspection under Sect. 91 comprises also an embodiment in which the vertical movement of the lever controls a second switch instead of contacts 16, 17 in order that a greater number of operations may be executed. This subject-matter does not appear in the Specification as accepted.

Abstract: 616,719. Automatic control systems for alternators. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Sept. 6, 1946, No. 26851. Convention date, Nov. 19, 1942. [Class 38 (iv)] [Also in Group XL (c)] In a thermionic voltage regulator for an alternator, the regulator amplifier which supplies the alternator field has a negative voltage feedback stage, tuned to double the generator frequency including at least the amplifier output stage. As shown, the output voltage at 3, 4 of the alternator 1 is applied through transformer 8 to the rectifying diodes 9, 10 the output from which is supplied to the grid 11 of pentode 5, operating as a quadratic detector. The output of valve 5 as developed across cathode resistor 13 is applied to the grid of pentode 6, the output of which, at resistor 14 is applied to grid 15 of the pentode 7, which supplies the energizing current to the alternator field 2. Negative voltage feedback from the output of valve 7 to the grid of valve 6 is effected through the condenser 16 to the voltage divider comprising the series connected resistor 17 and oscillatory circuit 18 tuned to twice the generator frequency, and the effect of armature reaction on the regulating system is thereby minimised. To increase the speed of action and the stability of the system and to eliminate harmonics of the ripple component of the input voltage, non-selective negative current feedback is effected from the valve 7 to valve 6 from the resistor 19 through condenser 20 to cathode resistor 21.

Title: Improvements in or relating to apparatus for taking samples of liquids
Inventor: PEARCEY ARTHUR FREDERICK
IPC: G01N1/14
Filed: 1958-08-25
Abstract: 926,132. Sampling liquids. WRIGHT HARGREAVES ENGINEERING CO. Ltd., and H. A. JOB Ltd. Aug. 25, 1959 [Aug. 25, 1958; Nov. 12, 1958], Nos. 27148/58 and 36310/58. Class 106 (5). Apparatus for taking samples from batches of liquids, in which means 10, 11 for withdrawing a liquid sample from a batch of the liquid, and for supplying the sample to a container 17 are responsive to two control valves 22, 23, the valve 22 being responsive to the presence of a container in the receiving position and the second valve, which is manually operable, being effective only if a container has actuated the valve 22. As applied to sampling milk from weigh-bowls in which individual batches of milk are weighed before being discharged therefrom for processing, the sample container 17 is placed on a platform 16 and thereby, against the action of a spring 20, depresses a shaft 18 connected to the table so as to operate the valve 22 connected in a compressed air circuit. In order to dispense a sample of milk from the weigh-bowl into the container, the manually-operable valve 23 is actuated which causes compressed air to be fed through a reversing valve 28 to one end of a double-acting ram 11, the ram-rod being connected to a piston within a cylinder 10. Movement of the latter piston draws milk from the weigh-bowl through a pipe 9 into the cylinder and, at the end of the stroke, a valve 30 is operated which reverses the valve 28 and thereby directs the air to the other end of the ram causing the piston to force the milk out of the cylinder 11, most of the milk returning to the weigh-bowl and the remainder being forced via a pipe 12 through the nozzle 15 into the container 17. The operation of the reversing valve 28 also directs the air supply through a pipe 32 and a further reversing valve 33 so as to actuate a ram 34 connected to a valve 35 and thereby discharge the contents of the weigh-bowl; a valve 50 is located in the pipe 32 in order, if desired, to prevent the weighbowl being discharged so as to permit a second sample to be taken therefrom. At the end of the dispensing stroke of the cylinder 10, a valve 40 is actuated so as to cause low-pressure air to be fed via a filter 41 through the pipes 9, 12 in order to completely drain the system. Further valves 26, 27, 51, 53 are provided for bypassing certain parts of the air circuit in order to permit cleaning liquid to be fed through the various components normally in contact with the milk. The apparatus, as shown, may be duplicated so as to take samples from two weigh-bowls, one apparatus being effective while the other is inoperative.

Title: Improvements in and relating to electrical communication systems
IPC: H04B3/10
Filed: 1937-10-07
Abstract: 509,140. Automatic volume control. TELEPHONE MANUFACTURING CO., Ltd., PADDLE, L. H., and FLINT, J. G. Oct. 7, 1937, Nos. 27230/37 and 19131/38. [Class 40 (iv)] [Also in Group XXXV] In an electric communication system in which volume is controlled in accordance with the amplitude of a pilot signal frequency transmitted over the system, transmission of the pilot signal beyond a control point is suppressed when control is being effected at that point. Absence of the pilot signal prevents control at subsequent points. Long lines may be subdivided into sections in which control is effected as above, but when control is being effected at any point in one section, the subsequent sections are still supplied with a pilot signal. As a control point may be in a condition to exercise control when a suppressed pilot signal is re-impressed on the line, arrangements are provided for avoiding unnecessary control. In the arrangement shown in Fig. 1, which effects control in a manner similar to that described in Specification 508,941, the pilot signal is separated from the input 10 of the main transmission channel by a filter FP and is normally impressed on the main output 10a over contacts of relay CO. Control of potentiometer P3 is effected by apparatus C subject to time delay at D as described in the above-mentioned Specification, and when C is functioning relay CO pulls up to open the through path of the pilot signal and to terminate the outgoing filter FP with a resistance R of the proper value. When the line is sectioned, a through path for the pilot signal is not provided, the outgoing section being supplied with pilot frequency by a separate generator. In the arrangement shown in Fig. 3 in which the output of filter FP passes to two parallel circuits, one of which comprises a valvecontrolled master relay K and the other the control circuits C proper, which can only function when K is operated by the presence of a pilot signal, as described in the abovementioned Specification, the relay K is provided. with additional contacts, one when operated disabling the delay circuit 21, 22 of relay K and the other when normal disabling the delay circuit 14, 15 of the control C. If the pilot signal has been suppressed, delay circuit 21, 22 which has a relatively short time constant is operative and K energizes when the pilot signal is re-imposed, but not until the pilot signal has quickly charged the condenser 15 of the control delay circuit, thus avoiding unnecessary operation of the control circuit due to absence of charge on condenser 15.
