Title: Improvements in or relating to pumps
Inventor: MORTON PAUL GREVILLE
IPC: A61M60/268
Filed: 1968-03-22
Abstract: 1,223,591. 591. Reciprocating pump. ENGLISH ELECTRIC CO. Ltd. March 21, 1969 [March 22, 1968], No.14005/68. Heading F1A. [Also in Division A5] An artificial heart pump comprises a diaphragm pump 10 operated by fluid from a control system including first and second pumps 19, 20 for pumping hydraulic fluid respectively into and out of chamber 13 of the diaphragm pump and a control valve 17 submerged in the hydraulic fluid for connecting the first and second pumps 19, 20 alternately to chamber 13 to move the diaphragm to cause blood to be pumped pulsatingly from the diaphragm pump 10. As described the control valve 17 is a spool valve 48 with a two land spool 42 which reciprocates in the body 43 so that pipe 18 leading to the pump is alternately connected to one of pipes 22, 25 (from pumps 19, 20 respectively) the other of the pipes being meanwhile blocked. The spool is reciprocated by eccentric 45 through connection rod 46 and spring coupling 72. Spool valve 48 is mounted on screwed rod 68 so that it can move axially but not be rotated. When the rod 68 is rotated by means of knob 30 valve 48 moves axially and the spool may thus be adjusted to remain longer in either the pressure applying or suction applying positions (i.e. opening pipe 22 or pipe 25 respectively to pipe 18). Preferably the two pumps run continuously. The diaphragm pump Fig.4, (not shown) may be a flexible tube (14) inside a rigid tubular body (65), the non return valves (15, 16) being mounted at each end.

Abstract: 406,890. Colorimeters; colour screens. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. May 17, 1933, No. 14293. Convention date, May 26, 1932. [Class 97 (i).] In colorimeters of the type in which a colour equal to that to be measured is obtained by mingling three primary colours, monochromatic prime colours are obtained by filtration of light emitted by spectrum lamps and the intensity of each is regulated in two independent ways, first to produce white light, and secondly, to modify such white light to the colour under test. Filtration is effected by semi - transparent mirrors formed by applying a thin coating of a dye such as indigo carmine, methyl violet or toluidine blue, to plate glass. Two mercury lamps A, C, and a neon lamp B, each disposed in front of an opal glass screen S, lens l and diaphragm d are arranged as shown with semitransparent mirrors 1, 2 coated respectively with indigo carmine and methyl violet. A filter f of didymglass (glass coloured with didymium oxide) coated with a yellow filter comprising picric acid in gelatine is disposed in front of the lamp C. Three colours of wavelengths of 637, 546 and 435 mÁ are thereby obtained which are thrown by a lens L on to a screen i covered by a diaphragm D. The body to be tested is mounted in front of the diaphragm and illuminated by a lamp W. In use, a standard white is placed in front of the diaphragm D and, with the diaphragms d fully open, the lamps A, B, C are adjusted relatively to the screens S until equality is obtained ; the body to be treated is then substituted and the diaphragms d are adjusted until equality is again obtained. A single mercury lamp may be employed instead of the two lamps A, C.

Filed: 1935-05-17
Abstract: 458,354. Tobacco-stemming machines. AMERICAN MACHINE & FOUNDRY CO., 511, 5th Avenue, New York, U.S.A. May 17, 1935, No. 14463. Convention date, Nov. 16, 1934. [Class 130] In a tobacco-leaf stemming-machine in which a leaf forwarding means and a stripping mechanism travel along divergent paths and the forwarding means grip the leaf stems and pull them through the stripping mechanism to strip the leaves therefrom, an auxiliary stem pulling device engages stems which have been missed by the forwarding means and pulls them through the stripping mechanism. Subsequently, a separating mechanism arranged at the side of the stripping mechanism remote from the forwarding means, engages and separates unstemmed leaves from those stemmed by the stripping mechanism. Leaves L placed manually on conveyer belts 41, 42 are gripped between a vertical pair of endless cables 46 while spirally carded rolls 78, 80 strip the butts from below and above, the leaves being pressed thereagainst by resiliently mounted tubes 82, 83 through which air is blown to assist the pressure, and then the stripped butts are gripped between a similar pair of cables 64. The upper runs 65, Fig. 4, of the lower cable are supported by a channel member 52<1> fixed to the main frame 25 of the machine and pressure is applied to the lower runs of the upper cable 64 by a similar channel member 541, on a pivoted arm 72, by a spring 75 on a bolt 74 mounted on the support 71 of the lower channel member 52<1>. The cables 64, 65 are offset from and parallel to the cables 46 to locate them opposite the stripped butts S of the leaves and any leaf which is not securely gripped by the cables 64, 65 is thrown aside by a spring-pressed pivoted arm 91. Set at an angle to the cables 64, 65 are upper and lower endless carded stripping belts each comprising a belt secured to a block 99, Fig. 16, riveted to a channel member 101 rigid with pins 103 on which are pivoted chain members 102 and guide blocks 105 running on guide surfaces on a supporting bar 106, the bar for the upper belt being adjustable to and from the lower one. The belts are set at the pitch line of the chain 102 and their sprockets.. Any stem not pulled through the stripping mechanism by the cables 64, 65 is caught between a belt 127 and a pulley 129, Fig. 18, and drawn therethrough, the belt being disposed close to the stripping mechanism and being constrained to pass around the pulley 129 by pulleys 130, 131. A pin 128 catches stripped stems and diverts them from the belt 127. Plates 124, 125, Fig. 4, on the supporting bars 106 for the carded belts strip the leaf fragments therefrom and unstemmed leaves are caught between delivery belts 141 on the side of the stripping mechanism remote from the cables 64, 65. Clearance of the stemmed leaves from the carded belts is ensured by leather &c. arms 156 on the upper pulley of the belts. Leaf fragments which cling to these leaves are blown therefrom on to the middle of a broad delivery belt 150.
