Title: Electrically Actuated Valve
Inventor: FAUSTINI ALBERT JOHN
IPC: F16K31/08
Filed: 1967-02-02
Abstract: 1,171,653. Valves. AMERICAN OPTICAL CORP. 2 Feb., 1967, No. 5197/67. Heading F2V. A three-way valve has formed in its body 10 a fluid pressure inlet duct 12 and two service outlet ducts 11 and 13, flow from the inlet to either one of the outlets being controlled by a cup-shaped member 18 movable across the inlet and outlet ducts and adapted to connect only two ducts in either one of its two operative positions. Member 18 is disposed within an aperture 20 formed in a linearly reciprocable permanent magnet 19, which magnet has disposed above it a solenoid 27 and together with the solenoid is surrounded by a casing 30. Into the core of the solenoid is fitted an internally screw threaded nut 25 which carries a screw 32 and has a flange bearing on the magnet, there being disposed between the nut and member 18 a spring 23 for biasing member 18 against the valve body. Direct current applied to the solenoid polarizes the casing which in turn causes the magnet, and hence member 18, to move in a direction dependent on the polarity, thereby bringing port 12 into communication with either one of ports 11 and 13, the redundant port then being vented to atmosphere through an outlet 33. If the pressure at the inlet 12 becomes excessive, it is then capable of raising member 18 so that the pressure in excess of that desired may be vented to atmosphere through port 33.

Title: Improvements in or relating to centrifugal extraction
IPC: D06F37/30
Filed: 1951-03-05
Abstract: A drum 24, serving as a tumbling, hydroextracting and drying drum, is enclosed in a casing 18 having a solvent supply pipe 40, a steam supply pipe 44, a solvent drain pipe 56 and vapour withdrawal pipes 50.  The drum is oscillated or rotated by belts <PICT:0687698/III/1> 36 driven by positive-displacement hydraulic motors 12, 14 supplied with oil from a tank 16 by rotary positive-displacement sliding-vane pumps 62, 64 driven by an electric motor 66.  The pump 62 is connected by a pipe 72 having a check valve 74 and bypass 118 to the hydraulic motors.  The pump 64 is connected by a pipe 82 to a reversing valve 84 which may direct oil into a pipe 88 connected with the hydraulic motors, into a pipe 94 connected to the pipe 72, or into a return pipe 86.  The pipes 72, 82 are connected to the return pipe by pipes 110, 112 and by pipes 102, 108 having pressure relief valves 100, 106 set at low and high pressures respectively.  Goods are placed in the drum and solvent is supplied by the pipe 40 for the cleaning step, during which the pump 64 drives the hydraulic motors to oscillate the drum, the valves 80, 96, 114 being open, the valves 116, 120 being closed, and the reversing valve periodically reversing the flow.  After the oscillation of the drum has been stopped by opening the valve 116, the solvent is drained by the pipe 56.  The drum is then rotated preparatory to hydro-extraction by closing valves 116, 80, and setting the reversing valve to supply pipes 94, 72 so that the pump 64 drives the motor 12, the motor torque being sufficient to rotate the drum but the capacity of the pump limiting the drum's speed to a critical speed at which the goods are distributed over the cross-section of the drum.  With the drum rotating at this speed the valve 114 is closed and valve 120 opened so that both pumps supply the motor 12, the motor torque being just sufficient to maintain the rotation of the drum at the critical speed.  When a balanced condition of the goods in the drum occurs the drum is accelerated for hydro-extraction until the volumetric capacity of the pumps is reached, the drum rotating at high speed without vibration.  After hydro-extraction is completed valves 114, 116 are opened and valve 96 gradually closed to stop rotation of the drum.  Valve 116 is then closed to cause pump 64 to supply oil to the motor 12 and rotate the drum at the critical speed for the drying step, which is carried out in the manner disclosed in Specification 649,785.
Patent GB-575555-A (GB)
Title: Improvements in or relating to methods of and apparatus for feeding statistical record cards
IPC: G06K13/077
Filed: 1944-03-21
Abstract: 575,555. Statistical machines. THOMAS, A., and RHODES, F. S. March 21, 1944, No. 5280. [Class 106 (i)] A method of feeding statistical record cards continuously through a device operating on each column in turn of a series of successively fed cards consists in reciprocating two card grippers in opposite directions to and from the device, the cards being gripped at the longer edge and passed from one gripper to the other when the grippers reach the inner ends of their travel, whereby interruption of the operations of the device between the last column of one card and the first column of the next is eliminated. A card from the magazine 2 is fed under a spring-pressed gripper 34 which is released to grip the card when a cam-controlled bellcrank 40 rotates clockwise thus forcing a short arm 47 against a pawl. 36 and unlatching the gripper. The carriage 23 is then pulled along a slide 22 by a coiled spring 30, connected by a flexible strip 31, under the control of a stepped cylindrical cam 24 co-operating with a follower 29 on the carriage. Thus the card is fed column-by-column through known reading means 19 comprising a vertically reciprocating pin box 3. A second carriage, controlled in a similar manner, grips the card at the other side of the reading means and conveys it towards an ejecting device. A smooth, helical portion 26 of cam 24 returns the carriage to its initial position. The gripper 34 is opened when cam-controlled belt-crank 40 is rocked anticlockwise thus bringing an arm 55 down on the tail 35 of the gripper 34.

Title: Photographic focusing screen camera
IPC: G03B5/06
Filed: 1973-02-02
Abstract: 1413743 Focusing screen cameras SINAR AG SCHAFFHAUSEN 2 Feb 1973 [4 Feb 1972]  5360/73 Heading G2A A focusing screen camera has an image carrier 13 and a lens carrier 11, either of which can be tilted with respect to the other, with means for indicating the angle of tilt, and with a pair of marks on the screen for use as a measuring base. The camera shown has a front carrier 11 for the lens 12, and a rear carrier 13 for a film cassette. A removable frame 14 carries a focusing screen 15. Both carriers are mounted on pivots 21 so that either may be tilted, as shown, and the pivots themselves are carried by slides 22 which slide in grooved member 23 which can in turn slide along a base 24 in the manner of an optical bench. Screen 15 carries two horizontal base lines 31, 32, equidistant from the centre point 33 of the screen, and whose distance apart is designated M. Two similar vertical lines 34, 35 serve the same purpose when the screen 15 has been turned through 90 degrees for a different format. It is assumed that two different points of an object at different distances from the lens are both required to be in sharp focus on the photograph, e.g. the front and rear corners of a book lying on a table which is being photographed obliquely from above. The camera in its basic position, with both carriers vertical Fig. 1, is pointed at the book so that the two corners appear on lines 31 and 32 respectively. The rear corner is sharply focused on line 31 by adjusting member 23 of image carrier 13 along base 24. The image plane is now considered to be at a distance S from the centre of the lens. Carrier 13 is now moved by slide 22 until the front corner of the book is sharply focused on line 32, and this distance is designated S. In order to ensure that both corners are in focus simultaneously, carrier 13 must be tilted rearwardly by an angle α, as shown in Fig. 2, the dimensions being related by the formula sin α =#S/M. However, when carrier 13 is tilted, the M distance of lines 31 and 32 from the lens will change, and so further adjustment of slide 22 is effected, thus bringing both corners into focus simultaneously. Graduated scales for the accurate control of the pivoting and sliding movements of carrier 13 are provided, and described in detail with reference to Figs. 5, 6 and 7 (not shown).
