Title: Improvements in and relating to pump controlling mechanism
IPC: F04D15/02
Filed: 1935-10-19
Abstract: 452,181. Centrifugal pumps. JENNINGS, I. C., 138, Flax Hill Road, South Norwalk, Connecticut, U.S.A. Oct. 19, 1935, No. 28922. [Class 110 (i)] [See also Group XXIX] An air pump C and a water pump D are mounted on a common shaft driven by an electric motor E. A float H actuates a switch I, I<1> to energize a solenoid to close the valve N in the pump delivery pipe O when the water in the tank A falls below a certain level. This ensures that the suction of the pump is always covered. The switch I, I<1> is also connected to the closing coil K of a three pole switch L controlling the motor E. A vacuum gauge F actuates a switch G also connected to the coil K. This ensures that the motor is stopped when the vacuum and water level in the tank A are at the desired value and that the motor is started when one or both of these values vary. The valve N may be actuated by a diaphragm exposed to pressure or vacuum which is varied by a control valve actuated through snap action by a float. The valve N may be spring loaded in the direction to close it and actuated by a piston Q<1> which is raised by pressure developed by a pump Q which draws liquid from above the piston Q<1> and delivers it to the underside. The pump Q is driven by an electric motor R controlled by the float H.

Abstract: 444,298. Typewriters &c. NAAMLOOZE VENNOOTSCHAP KAMATEC, 29, Rokin, Amsterdam. Oct. 19, 1935, No. 28923. Convention date, Oct. 20, 1934. [Class 100 (iv)] [See also Group XIX] Relay type bar actions; hammer-impression arrangements- -In a perforatedcard - controlled device for setting members, particularly type-bars or wheels, the member or another coupled therewith is situated between the arms of a pair of scissors, one of which, synchronously with the feeling operation on a card, moves towards the other, which is held up, until, the feeling of the perforation causes the first arm to be arrested and the second to be released to move towards the first, synchronously with the remainder of the operation. In the mechanism shown in the Figure, a cam-shaft rotating once for every machine cycle carries a box-cam n controlling one arm h of the scissors, and a cam o which draws back and releases hammers p. The arm h is at first restrained by a pawl k, so that rotation of the cam n from the position shown (corresponding to the beginning of the feeling operation) depresses the other arm e of the scissors about the fixed pivot g. When a perforation passes between roller and feeler a magnet t is energized, thereby withdrawing the pawl k and placing its other end k<2> in position to engage that tooth of a segment f on the arm e which is, at the moment, opposite it. Continued rotation of the cam n now moves the arm h about the pivot j and raises the typebar a through the agency of a pin d. After the hammers are operated under the action of a spring o<2>, and before they are restored, the arms h, e are restored by a spring h<1>, the arm h first moving back to contact a stop h<2>, against which it is held by the latch k, and the arm e then returning to rest A subsequent operation picks up the type-bar from its previous position and either the arm h or the arm e, according as the new sign is lower or higher than the previous one, moves it to its new position. A rack for setting a type-wheel or counting-disc may be substituted for the bar a.

Title: Improvements in and relating to voltage regulating systems
IPC: B65H23/198
Filed: 1946-01-30
Abstract: 613,096. Automatic regulation WINTHER, M. P. Jan. 30, 1946, No. 28997. Convention date, May 4, 1944. Divided out of 613,052. [Class 38 (iv)] A voltage regulating system is arranged to produce in the secondary winding of a transformer an output voltage which has a substantially straight line characteristic and is proportional to the current in a polyphase circuit supplying an A.C. motor under variable load. As shown, a 3-phase motor W.M. is connected to lines L1-L3, which have the primary winding of a current transformer T11 connected across lines L1-L2. A resistance R13 connected across the secondary winding of transformer T11 has a variable tapping 33 connected to one end of the secondary of transformer T10, the other end being connected to one end of the primary winding of an output transformer T9, which is shunted across a resistance R12 with a tapping 32. Resistances R12, R13, have a common junction joined to one end 34 of the secondary of transformer F11. The tapping 33 on the resistance R13 is adjusted until the voltage derived from transformer T11 cancels that derived from T10 when'the motor is idling, i.e. it bucks down the component of the current produced in T10 by the magnetisation current of the motor. The subsequent load-ampere characteristic of the motor is substantially a straight line, and a straight line relationship is obtained between the secondary Voltage of transformer T9 and the torque of motor W.M. The slope of the line can be changed by adjustment of tapping 32 on potentiometer R12.

Filed: 1931-10-23
Abstract: 390,551. Combustionproduct plant. WILLENBORG, W. J., 1201, Hudson Street, Hoboken, New Jersey, U.S.A. Oct. 23, 1931, No. 29448. [Class 7 (i).] In a method of regulating the performance of an inert gas generating plant comprising an internal-combustion engine and a compressor, the exhaust gases of the engine are intercepted until they reach a predetermined pressure and are then admitted to the intake of the compressor, and gases from the compressor outlet are bye-passed to the compressor intake when the pressure of the gas at said intake falls below a predetermined miniumm. In the plant shown, the exhaust from the engine 1 passes through a scrubber 4 and pipes 5, 17 to the compressor 12, and thence by a pipe 18, a cooler 26 and a separator 27 to a highpressure tank 34. A valve 20 in the pipe 5 is controlled by the pressure of the exhaust gas acting on a diaphragm 39 in a chamber 21, so that the valve opens when the pressure is more than 2 lbs. above atmospheric. The outlet pipe 18 of the compressor is connected to the pipe 17 by a byepass 35 provided with a valve 36, controlled by the pressure in the pipe 17 and arranged to open when this pressure is below atmospheric. The pressure on the intake side of the compressor is thus maintained within convenient limits, preventing excessive load on the compressor. The outlet pipe is also provided with a loaded valve 30 which opens towards the tank 34 only when the pressure exceeds a predetermined pressure such as 6 atmospheres. Any leakage around the valve piston is returned by a pipe 42 to the pipe 5. Two solenoid-controlled valves 32, 33 are arranged to open to the tank 34 and to the atmosphere respectively; one or other valve is operated, according to the quality of inertness of the gas, by a device such as that described in Specification 352,006, connected through a pipe 41 to the pipe 5.

Abstract: 877,069. Sensing record cards. CREED & CO. Ltd. March 21, 1960 [Sept. 1, 1959], No. 29741/59. Class 106 (1). In a photo-electric perforated record senser the light is caused to pass through the hole more than once by a mirror set at an angle. The signal derived from a beam passing once through a perforation in a record tape and that from a beam striking an unperforated part of the record may be in a proportion as small as 2 to 1 because of the translucency of the record. Passing the beam twice through the record ensures that the beam at an unperforated position is heavily attenuated and that a more positive signal difference is obtained to represent mark and space. In the form of Fig. 2 the beam from lamp 3 is reflected by mirror 5 back through the same hole in record 2 and impinges on photocell 1. Where the tape is unperforated the beam is scattered 7, that part passing through the record being additionally reduced by the return passage. The mirror 5 is set at an angle so that the scattered light 7 does not fall on the photocell 1. In Fig. 3 the light beam is passed three times through the record perforation by mirrors 12, 14, 15 and 17 and lenses 13 and 16. Specification 877,070 is referred to.
