Title: Improvements in centrifugal pump installations
IPC: B64D37/16
Filed: 1955-05-17
Abstract: 775,161. Centrifugal pumps. LEDUC, R. May 17, 1955 [May 17, 1954], No. 14171/55. Class 110 (1). In a centrifugal fuel pump for an aircraft, the suction conduit includes an injector fed by liquid bled from the delivery, and a vessel of relatively large capacity is provided between the injector and the pump inlet and above the level of the pump and injector, the upper part of the vessel constituting a collector space for vapour and gases, the space being vented, preferably through a non-return valve. A centrifugal pump 2 draws liquid from a tank 6 by way of a pipe 5 and an air separator 7 and discharges it to a delivery pipe 1a. Separated air is returned to the tank 6 by way of a non- return valve 11 and pipe 9. To avoid evolution of gas and vapour at the pump inlet 12, the inlet is pressurized by means of an injector in the pipe 5, comprising a venturi 4b and a nozzle 4a fed with liquid bled from the pump discharge through a pipe 10. Any gas or vapour present at the inlet 12 is sucked through a pipe 19 and non-return valve 24 back to the tank 6 by means of an injector 20, 21 fed with liquid bled from the pump discharge through a pipe 22. Priming is effected by a positive-displacement pump, such as a gear pump 23, connected between the bottom of tank 6 and the pump inlet 12. In some installations, such as fuel systems for ram-jet propelled aircraft, it may be desirable to cut off the supply to the pump 2 when the liquid in tank 6 reaches a low level, and this is ensured by arranging that, as shown, the pipe 5 does not extend to the bottom of the tank. The pump 23 delivers enough liquid to the pump 2 to prevent the latter from seizing under these circumstances. The pump 2 may be of the double-inlet type, with separate members 19, 20, 21, 22, 24 for each inlet.

Title: Method of producing an antitoxic medicament
IPC: A61K39/00
Filed: 1924-06-11
Abstract: 239,302. Deutschmann, R. H. June 11, 1924. Antitoxins ; medicines for internal use; yeast. -Antitoxic medicaments are obtained by growing non-pathogenous yeast cells in a liquid containing bacterial toxins prepared in vitro, or blood containing a toxin, or juices expressed from malignant tumours, pustules, &c., there being no living bacteria &c. present in the liquid. The yeast cells so obtained may be separated and dried together with the liquid, and formed into tablets ; or preparations may be obtained by mechanical destruction of the yeast cells, or by digesting them with pepsin and hydrochloric acid. In examples, the yeast is grown on a liquid obtained by rinsing an agar culture of bacteria with sterilized broth, cultivating the bacteria in the broth, sterilizing the broth culture by repeated heating to 50‹ C., filtering through a bacteriological filter, and adding malt beer or sugar solution. The remedies may be administered by inoculation or through the digestive. system.

Title: Decrystallizing means for absorption refrigeration systems
Inventor: REID JOHN GRAHAM
IPC: F25B15/06
Filed: 1965-04-03
Abstract: 1,036,169. Refrigerating. AMERICAN RADIATOR & STANDARD SANITARY CORPORATION. April 3, 1965, No. 14215/65. Heading F4H. In an absorption refrigeration sytem means are provided for sensing the formation of crystals in the hot solution side of the liquid heat exchanger and directing hot generator solution through the other side of the heat exchanger to melt the crystals. As shown, relatively weak solutions from a pool 74 in the shell 10 containing the generator 16 and condenser 18 passes to the absorber 44 through tubes 58 and 64 via one pass of a liquid heatexchanger 60. If crystallization occurs in the latter the level of pool 74 rises sufficiently to complete an electrical path between electrodes 78, 80 thus closing a relay contact 90 which opens a valve 94 in a line 98. The latter supplies hot solution from pool 74 to the lower portion of the shell 12 containing the absorber and evaporator, the hot solution being then forwarded by pump 70 through the other pass of heat exchanger 60 to melt the crystals. At the same time pump 48 which circulates cooling water through the absorber and condenser is de-energized by contact 90 thus effectively rendering the condenser, absorber and evaporator inoperative and causing a pressure rise in shell 10. This rise in pressure results in less refrigerant being evolved in the generator so that the solution supplied through line 98 is of substantially the same concentration as that normally present in the bottom of shell 12.

Abstract: 144,543. Haddan, A. J. H., (National Cash Register Co.). March 7, 1919. Hammer-impression arrangements.-The impression-device or hammer of a cash register or like machine is associated with a member which is moved in advance of the impression-device into engagement with the record-material and operates means for preventing the impression-device from making an effective stroke when the recordmaterial is absent. The invention is shown in Fig. 1 as applied to the machine described in Specification 144,373, and comprising type-wheels 288 and an impression-hammer for printing data in a bank book and upon a duplicate card; the hammer strikes twice at each operation of the machine, and the book and card are placed on a carriage 467 which is associated with feed-mechanism for removing the card when it has been printed upon. The hammer 543 is carried by a lever 544 which is loose on a shaft 354 and is provided with a pin 578 engaging a slot 579 in a loose lever 580, a spring 581 being arranged between a pin 582 on the lever 580 and the pin 578. The tail 597 of the lever 580 is forked to engage a lever 584 which is provided with rollers 591, 592 for engaging cams 593, 594. Twice during each operation of the machine, the cams allow a tensioned spring 586, arranged between the levers 580, 584, to rock the levers, the movement being limited by a stop 596. The hammer then completes its stroke by momentum and independently of the levers. An arm or feeler 599, loose on shaft 354 and having a part 608 for engaging the book or card, is connected to an arm 602 on a rock-shaft 603 provided with arms 604 having pins 605, adapted to engage lugs 611 on the hammer 543. At each operation. a yoke 494, Fig. 4, is rocked to remove a pin from the feeler 599, and a spring 606 rocks the feeler and the associated devices. if the book or card is present, the feeler 599 is arrested thereby and the arms 604 do not carry the pins 605 into the path of the lugs 611. If the book or card is not present, the stroke of the feeler increases and the pins 605 enter the path of the lugs 611 and prevent the hammer from completing its stroke.

Abstract: 585,473. Valve receiving circuits. STANDARD TELEPHONES & CABLES, Ltd., and WILLOUGHBY, E. O. Aug. 1, 1944, No. 14700. [Class 40 (v)] In a radio distance determining arrangement depending on the frequency sweep principle, a leaky grid detector for determining the frequency difference between the outgoing and incoming signal, has its grid effectively earthed at high frequencies and the two signals rare fed onto the cathode circuit ; thereby ensuring a low input impedance at high frequencies, :at which the anode circuit comprises a low impedance byepass circuit, while presenting a high impedance at the detector signal frequency. The detector valve 1, Fig. 1, which is of the grid disc type as disclosed in Specifications 585,448, 585,449, 585,450, 585,452 and 585,454 is mounted in a screening case ; whose parts 8, 9 of different diameters are connected by the apertured disc 10 'whose capacity 11 with the grid disc 5 effectively earths the grid at signal frequencies. The two frequencies whose difference is required are fed to the cathode from the coaxial conductor 17 to the lead 15 and the casing 8 which forms with conductor 14 a resonant cavity. Grid leak resistance 18 is connected to earth or to a suitable source of AVC. Condensers 21, 23 and capacitative transmission line 25 together with chokes 22, 24, 26 form a low-pass filter permitting transmission of the detected frequency only. In cases where the detected frequency is of the same order as the signal frequency and consequently capacity 11 must be made smaller the.grid may be connected to earth by means of a series circuit resonant at the signal frequency. In an alternative arrangement, Fig. 2, both transmitted and reflected waves are received on a half-wave dipole 30, coupled by condenser plates 32, 33 separated by mica sheet 31, to a short transmission line stub to give it a band pass characteristic and to the quarter wave transmission line leading to the cathode of the valve. The filament lead within tube 14 is decoupled by the capacity 16, 12.

Divided out of Complete Specification of 585,911. Drawings to Specification. [Classes 40 (vi) and 40 (vii)] A radio distance-measuring apparatus which is adapted to produce indications or a control effect at specific distances comprises at least two aerial systems radiating signals from separate oscillators on wavelengths which are different submultiples of a predetermined value. Reflected signals cause the effective impedances of the aerials to change as the distance from the aerials to a reflecting body changes, the impedance becoming a maximum when the aerial-reflector distance is a halfwavelength or multiple thereof. The radiofrequency aerial voltages are rectified by diode detectors and the resultant fluctuating D.C. potentials are amplified by separate D.C. amplifying stages which feed a common indicating device such as a relay. The desired indication or operation is thus obtained when the maximum impedance effects in the several aerials coincide, this coincidence occurring when the distance is a multiple of the wavelengths of the separate oscillators.

A welder's eye shield has a clear window 9 and a sheet of tinted glass 20 movable in front of it by means of a manipulating member adjacent the handle 33, said member being movable in two directions to position the sheet 20 in front of window 9 and to latch it in said position respectively. The member preferably comprises a bent lever having parts 27, 28, 29, 30, 32 which is rotatably and axially movably mounted in a part cylinder 26 fixed to the handle 33. The lever is rotated clockwise by finger grip 32 and part 30 lifts sheet 20 up to window 9. When sheet 20 is in position the lever is moved axially so that part 30 is latched in a notch 31 in the shield frame. The lever is then so positioned that if it was accidentally unlatched the weight of sheet 20 would try to rotate it clockwise but since the lever is off-set and is prevented from further clockwise rotation by the handle, the window is maintained in position. Specification 574,264 is referred to.
