Title: Improvements relating to Liquid Applicators
IPC: G03B17/50
Filed: 1968-06-05
Abstract: 1,182,305. Liquid applicators. INTERNATIONAL POLAROID CORP. June 5, 1968 [June 7, 1967], No.26731/68. Heading G2A. An applicator 54 for applying a predetermined uniformly distributed quantity of processing liquid to exposed photo-sensitive material 22 is formed by members A, B including a variable volume chamber 56, the members being relatively movable between a first position as shown in which they define a capillary channel 64 and a second position Fig. 3 (not shown) in which the channel 64 is sealed. The chamber 56 is filled with fibrous material 68 which is supplied with processing liquid from a reservoir. The material 68 is compressed when the member B is moved to the first position, thereby causing processing liquid to enter the capillary 64, along which it advances to coat the material 22 which is guided between a roller 70 and a support surface 62 of the member A. Members A, B are connected through elastically deformable means 76 which is deformed by rotation of a cam 78 which moves the member B to the first position. A second elastically deformable means 82 is also provided, a surface 84 of the member B resting on the means 82 in the second position to close the channel 64. The applicator forms part of a photographic copying apparatus Fig. 1 (not shown) in which a document is imaged on to a web (22) by a lens and mirror, the web is then advanced past the applicator (54) and into a development section where the leading end trips a switch (98) to cause a knife (32) to sever the web, thus ensuring that all the exposed section of the web is coated with processing liquid. The developed section is ejected from the apparatus.

Title: Improvements in hydraulic motors
Inventor: SEDGWICK ROBERT KING
IPC: B30B15/18
Filed: 1950-11-02
Abstract: 678,999. Hydraulic presses. AMERICAN STEEL FOUNDRIES. Nov. 2, 1950, No. 26756150. Class 69 (ii) A hydraulic press having a ram 4, Fig. 1, reciprocable within advance and return chambers 8, 10 to and from which oil is alternately delivered and exhausted, e.g. by a reversible pump 24 has an actuating circuit including a valve 67 having opposed pressure areas acted upon by pressure oil in the chambers 8, 10 respectively when the pressure difference therein exceeds a predetermined value to open and so permit oil to flow between the chamber 10 and a reservoir 20 and at other times to close and so prevent said flow, and also a prefill valve 48 between the advance chamber 8 and the reservoir 20 housing relatively great and small closing and opening pressure areas both acted upon by pressure in the chamber 8 in the closed position of the valve 48 ; the valve 48 also housing an additional opening pressure area open to the return chamber 10. As shown the valve 67 slides in a bore 62, 64 of the valve 48 which in turn is located in a bore 40, 42 of a body 38 and is urged to its closed position by a spring 70. To effect downward displacement of the ram 4 oil is delivered by the pump 24 along ducts 26, 30, Fig. 2, to the chamber 8 and the reservoir 20 through the open valve 48. Simultaneously the pump draws oil from the chamber 10, ports 14 and ducts 12, 32, 28 at a rapid rate until the ram meets the workpiece whereupon oil return falls suddenly. The resulting pressure drop acts through a duct 60 and a port 58 on the underside of the head of the valve 48 to close it, and on a plate valve 72 to open it thus allowing pressure to rise in chamber 8 and free flow of oil from the reservoir 20 through a port 44, the valve 72, the port 58 and ducts 60, 32 to the pump inlet. To return the ram 4 the pump 24 is reversed and rise in pressure in the port 58 acts on the underside of the head of the valve 48 to open it and relieve the oil trapped in chamber 8 to the reservoir 20. Simultaneously the valve 67 closes and cuts off the reservoir 20 from the ducts 60, 32 to allow pressure build up in the return space 10. In a modification the first mentioned valve is located in a bore adjacent to bores 40, 42. In both constructions relief valves 76, 80 are located between the valve body 38 and the reservoir 20.

Abstract: 1,107,826. Electric selective signalling. NAUTSHNO - TECHNITSHESKA LABORATORIA ZA MEDIZINSKA APARATURA PRI M.N.Z.S.G. 25 June, 1965 [29 June, 1964], No. 27164/65. Heading G4H. Row lines in a matrix are connected with column lines at at least some cross-points by means of a diode in series with a weighted resistor. To diagnose diseases, rows of the matrix, corresponding to diseases, are scanned in turn, to deliver currents to matrix columns corresponding to symptoms, via diode-weightedresistor combinations at some matrix crosspoints. The resistor weight is inversely proportional to the specificity of the corresponding symptom to the corresponding disease. Keyboard switches, closed according to the symptoms present, pass some of the column currents to an adder consisting of an ammeter or operational amplifier. When the adder output exceeds a preset value, scanning is stopped to allow the disease identity to be read on an indicator associated with the scanner. As scanning takes place, the sensitivity of the adder is adjusted by the connection of appropriate shunting resistors. The symptoms not entered on the keyboard but relevant to a particular disease are indicated optically as that disease is scanned, so by not operating any keys all symptoms relevant to each disease in turn are indicated. The invention may also be used for fault or organism identification.
