Title: Improvements in or relating to photo-electric colorimeter flow cuvettes
IPC: G01N21/05
Filed: 1959-09-03
Abstract: 899,298. Photo-electric measurement of colour. TECHNICON INSTRUMENTS CORPORATION. Sept. 3, 1959 [Sept. 12, 1958], No. 30088/59. Class 40(3). A photo-electric colorimeter for the examination of a liquid comprises a cuvette or horizontal member positioned to allow light to be passed through the liquid during its flow through the horizontal part which is connected at its opposite ends to vertical inlet and outlet tubes providing corresponding inlet and outlet spacings which are at a higher level than the horizontal member, and the vertical parts are vented at points above their points of connection to the horizontal member. The horizontal tube 180 forming the cuvette 118 through which the liquid is circulated is mounted in members 114, 132 which are adjustable horizontally. Light from a source 34 passes to a housing 62 comprising oppositely disposed apertured concave mirrors 68 to 70 and is focused on the end of the tube 180 after traversing a filter assembly 94 comprising appropriate filters 102, 110, 112 and 122 separated by apertured members 96 and a distance piece and a second distance piece 100, the filter assembly being supported on an L-shaped bracket 78. The emergent beam passes through apertured members 132, 166 to a photo-electric cell 136 supported on an adjustable L-shaped support 150. The space 124 between the housing 62 and filter assembly 94 is closed by a spring-biased sleeve 128, whilst a similar space 160 adjoining the photo-electric cell 136 is made light-tight by a cylindrical member 162 which can be moved to the right against the action of a spring 164. Liquid is fed to the tube 180 by an inlet tube 176 leading to a vertical tube 172 tapering at 190 to a curved portion 192 with a portion 220 defining an inlet above the tube 180. The inward flow is disturbed by a projection 188 to break up air bubbles and the tube 172 is vented by the tube 182. The tube 180 has also a projection near the inlet orifice, and further air released is vented by a vertical tube 194 connected at 214 to the tube 182. At the outlet end of the tube 180 liquid flows through a bent tube 200 and over a curved portion 222, defining the outlet level, to a pipe 174 connected via a rubber cap 234 to an adjustable output nipple 232. Air formed in the tube 180 is vented by a vertical tube 204 connected at 208 to the tube 174. The photo-electric cell and its housing together with the supporting member 132 for the right hand end of the tube 180, and the L-shaped member 78 for the filter assembly 94 may be secured to the plate 12 at fixing points corresponding to specified lengths of the tube 180. Specification 774,711 is referred to.

Abstract: 482,462. Measuring efficiency of lubricants. MOORE, S. BRAMLEY-. Nov. 5, 1936, No. 30089. [Class 106 (ii)] Comprises a slidable member having its opposed faces parallel to one another, two parallel flat surfaces between which the slidable member is located, means to cause the said two surfaces to be pressed towards one another and means for measuring the effort required to move the slidable member between said surfaces when lubricated with the oil to be tested. In the bottom of the dished base a to contain oil is provided a raised surface a<1> on which rests a disc or plate c guided by a tongue c<1> engaging a groove a<2> in the base plate. In an opening in the cover b is disposed a motor d the spindle of which carries a disc d<2> and means (not shown) are provided to lower the motor so that it and the disc d<2> rest on the disc c. A projection c<2> from the plate c is constituted as a hollow plunger provided with a non-return valve c<5> which fits into a cylinder e having a closed end with a transverse bore through which passes a rotatable plug f carried by the cover b. A recess in the plunger receives the end of an arm g carried by the shaft h a second arm g<2> extending horizontally and being acted upon by an adjustable spring i or by a weight. The cylinder is provided in the top with a restricted orifice e<2> and with a large orifice e<3> in the end wall. The plug may be turned so that a passage f registers with or closes the orifice e<2>. A thermometer j is provided as shown. The surface a<1> instead of being fixed may be made rotatable and suitable means for driving provided. To measure viscosity, a predetermined quantity of oil is placed in the casing and the plunger withdrawn from the cylinder so that the latter is filled, the outlet e<3> being closed. The loading on arm g<2> to expel the oil through orifice e<2> is a measure of the viscosity. If the orifice e<3> is wide open, the effort required to move the slidable member will indicate the " static friction value " of the oil. If the disc d<2> be permitted to rest on the member c and is rotated, the effort required to move the member c will indicate the " dynamic friction value " of the oil. The plunger and cylinder may be dispensed with and the effect measured when disc d<2> has been raised clear of c.

Abstract: 1329166 Packaging APPARATENBOUW MOBANV 1 July 1971 [1 July 1970] 30786/71 Heading B8C [Also in Division F2] A device for successively discharging objects from holders moving one after another along a predetermined path comprises rails 1, 2 for guiding rows of holders, not shown, each having a catch for discharging one, or more, objects carried thereby; a number of gravity-controlled latches 4 1 -4 6  which are swingably mounted on a stationary shaft 3 and each has a control wheel 7 and an arm 5 which tends to swing anti-clockwise and which is adapted to cooperate with a stopping surface 11 in a corresponding notch 10, a series of which are formed in a control cylinder 8. The stopping surfaces 11 are equi-angularly spaced. The cylinder 8 which carries a corresponding number of equi-angularly spaced discharge abutments 12 1 -12 6 , is used to rotate clockwise under the influence of a weight 14 and cord 13 and, since the abutment surfaces 11 are successively offset radially in the opposite direction to that of the cylinder 8, only the latch 4 1  is operatively engaged with its abutment 11 when the cylinder 8 is fully wound. As holders pass down the rails 1, 2 the latches 4 1 -4 6  are successively tripped, but only the one which is in positive engagement with its stopping surface 11, initially the latch 4 1 , is operative to release the drum 8 for clockwise rotation until the next latch, in this case 4 2 , is brought into abutment with its stopping surface 11. The abutment 12 1  makes contact with the discharge catch of the first holder adjacent latch 4 1  to release the object, or objects, carried thereby immediately after the latch 4 2  engages its stopping surface 11. The latches 4 2 -4 6 , which become operative one after another as the drum 8 correspondingly unwinds step-by-step, are released in turn from their abutments 11, the associated abutments 12 2 -12 6  correspondingly successively releasing the objects carried by the holders. The drum 8 is then rewound by a drive shaft 36 which is driven by a one-revolution clutch (32), Figs. 7, 8, not shown, and which is connected by a cam 55 and link mechanism 61-64 to a rotary shaft 9 which fixedly carries the drum 8.

Abstract: 717,477. Pumping apparatus for delivering measured quantities. MULLER, J. Dec. 4, 1952 [Feb. 29, 1952], No. 30824/52. Class 102 (1). A measuring pump 7 is manually driven through a handle 8 and fitted with a counter 9 to indicate the quantity delivered to the outlet 13. The liquid is supplied to the pump through a de-aerating tank having a baffle 5 between the inlet 2 and outlet 6 and a float 14 which is connected to a valve 12 by linkage 15, 16, 17 so that the valve 12 is closed when the float reaches a predetermined minimum level. In a modification, the pump is driven by an electric motor and the float actuates a switch to energize an electromagnet to close the valve 12 and in addition to' stop the motor. Fig. 3 illustrates a further modification in which the pump 7 is driven by a prime mover 28 through a clutch 29. When the valve 12 is closed, the increase in pressure opens valve 32 and actuates a spring- loaded piston 33 to disengage the clutch. The float 14 also operates a valve 37 to open and close it simultaneously with valve 12 so that-, pressure is released from cylinder 31, and the clutch engaged, when the valve 12 is opened. The clutch may be operated manually by a lever 39 if it has not been disengaged by piston 33. The supply tank or de-aerating tank may be supplied by a pump 40 under the control of the valve 41.
